Description

DESCRIPTION OF THE DRAWINGS

[0031] An embodiment of the invention is explained below with reference to FIG. 1. FIG. 1 shows a vertical section through a construction site device, having a climbing formwork device comprising a climbing formwork platform, a construction elevator fixed to the climbing formwork device, and an elevator system which is able to be adjusted to the building height.

DETAILED DESCRIPTION

[0032] FIG. 1 shows a schematic representation of a construction site device 1 within a building 2 which is in its construction phase. A building core 3 of the building, which is to be constructed from concrete and has already reached a certain initial height, is shown. The building core comprises a first elevator shaft 4 and a second elevator shaft 5 adjacent and parallel to it, wherein two living or office areas adjoining the elevator shafts and comprising several floors 7.1-7.X+5 are indicated starting from a floor level 8.1.

[0033] Here and in the following, the letter “X” stands for an indefinite number of floors below the building region shown.

[0034] The building core 3 is created using a known climbing formwork technique. A climbing formwork device 10 which comprises a climbing formwork platform 10.1 is installed in the currently uppermost region of the building 2 which is in its construction phase. The climbing formwork platform 10.1 extends over the entire region of the building core 3 and supports formwork walls 10.2 above its climbing formwork platform 10.1. In order to be able to produce a further section of the concrete walls forming the building core 3, the climbing formwork platform 10.1 with the formwork walls 10.2 is gradually raised, with a corresponding amount of concrete and reinforcement mesh being placed between the formwork walls 10.2 after each raising.

[0035] In order to be able to transport construction personnel, building materials or tools as effortlessly and in the most time-saving manner possible to the emerging floors and the uppermost region of the building 2 or the building core, an elevator system 15 which is able to be adjusted to the building height is installed in the first elevator shaft 4. This elevator system 15 comprises a mechanical platform 15.1 with an elevator drive machine 15.2, wherein the elevator drive machine carries and drives suspension cables 15.4 via a traction sheave 15.3, with which suspension cables an elevator car 15.5 and a counterweight 15.6 are suspended from the mechanical platform 15.1 and are moved up and down. The mechanical platform 15.1 can be raised in steps in a known manner—which is indicated in FIG. 1 by the arrow 14—and can be temporarily fixed at a higher level in the first elevator shaft 4, such that the conveying height of the elevator system 15 and/or the elevator car 15.5 can be gradually adjusted to an increasing height of the building 2 and/or of the building core 3, by also lengthening the supporting cables 15.4 accordingly. A so-called hoisting platform 15.7, which can be temporarily fixed above the mechanical platform in the first elevator shaft 4 and which comprises a first hoist 15.8 with which the mechanical platform 15.1 can be raised via a first traction means 15.9, is used to raise the mechanical platform 15.1. After such a hoisting process, the mechanical platform 15.1 is fixed again in the first elevator shaft 4, such that the elevator system 15 is ready for operation again with an increased usable conveying height after its suspension cables 15.4 have been extended. The hoisting platform 15.7 is raised to a higher level in each case before the mechanical platform 15.1 is raised. For this purpose, a second hoist 15.10 can be attached to the hoisting platform, which generates the required hoisting force via a second traction means 15.11 fastened to a fixed point 16 present in the elevator shaft.

[0036] During the construction phase of the building 2, the elevator system 15 able to be adjusted to an increasing building height serves on the one hand to transport construction personnel and building material to work sites on all floors 7.1-7.X+7 of the building that are already accessible, and on the climbing formwork platform 10.1 of the climbing formwork device 10. On the other hand, during the construction phase, the elevator system 15 transports both users of lower floors 7.1-7.X that are already inhabited or commercially used, as well as furniture and other objects belonging to these users. After completion of the construction phase and after carrying out certain modifications to the elevator system 15—for example, dismantling the hoisting platform 15.7 and finally fixing the mechanical platform 15.1 in the shaft head of the first elevator shaft 4—the elevator system 15 able to be adjusted to the increasing building height can continue to a substantial extent to be used permanently as a normal passenger elevator and/or goods elevator in the same elevator shaft 4.

[0037] The use of the elevator system 15 able to be adjusted to the increasing height of the building to transport people and material to the floors 7.X+3-7.X+7 that have already been built or are in the process of being built in the uppermost region of the building leads to the problem that the elevator car 15.5 of this elevator system 15, which is arranged completely in the region of the currently existing height of the first elevator shaft 4, is not able to travel up to an uppermost shaft region, which can be up to thirty meters high, and therefore in particular cannot transport the construction personnel into the region of the climbing formwork platform 10.1. The cause of this problem is on the one hand that the mechanical platform 15.1 is arranged above the elevator car 15.5, the hoisting platform 15.7 above the mechanical platform, and a device for lifting the hoisting platform and parts of the climbing formwork device 10 are arranged above the hoisting platform, wherein these components are all below the currently uppermost shaft end 4.1 of the first elevator shaft 4. On the other hand, the conveying height of the elevator system 15, able to be adjusted to an increasing height of the building 2 or the building core 3, is not adjusted every time after a new floor has been created, since such an adjustment is associated with a relatively high amount of work. Usually, the conveying height is not adjusted until three to six new floors have been built since the last adjustment. FIG. 1 shows the elevator system 15 in a situation in which two additional floors have been created since the last adjustment of the conveying height, such that both the hoisting platform 15.7 and the mechanical platform 15.1 and the elevator car 15.5 attached to it could be shifted upwards by two floor heights H in the first elevator shaft 4.

[0038] The above-described problem, that a comparatively high uppermost shaft region cannot be reached by the elevator car 15.5 of the elevator system 15 able to be adjusted to the increasing building height, is remedied according to the invention by using a construction elevator 20 cooperating with the mentioned elevator system 15. This construction elevator 20 is preferably installed in the currently uppermost shaft region of a second elevator shaft 5 which is as close as possible to the first elevator shaft 4. This second elevator shaft 5 grows upwards during the construction phase of the building together with the climbing formwork device 10 and with further walls of the building core 3, wherein a first shaft wall 5.1 of the second elevator shaft 5 has been provided with shaft door clearances 5.1.1-5.1.6 during the incremental construction of the building core, wherein the sill level thereof matches the corresponding floor level. The construction elevator 20 can extend in the vertical direction over five to ten floors of the building 2. Of course, the construction elevator 20 could also be installed in the first elevator shaft 4, if it is a so-called multiple elevator shaft. The construction elevator 20 is dimensioned in such a way that a construction elevator car 20.2 of the construction elevator can be moved between a floor level 8.X+7, 8X+6 lying above or below the climbing formwork platform 10.1 of the climbing formwork device 10 and at least the floor level 8.X+1 that can be reached as intended by the elevator car of the elevator system 15 able to be adjusted to the building height.

[0039] The construction elevator 20 comprises a self-supporting construction elevator frame 20.1 which extends substantially over the entire conveying height of the construction elevator and which is preferably constructed from steel profiles. Inside this construction elevator frame 20.1, guide rails—not shown in FIG. 1—for guiding a construction elevator car 20.2 are installed. The four vertical inner sides of the construction elevator frame are covered with wall panels—also not shown—that form flat and smooth shaft walls for the construction elevator. In one of the side walls of the construction elevator frame 20.1 and in the wall panels belonging to this, at least two access openings 20.3.1-20.3.7 arranged one above the other are recessed, the position of which in the installed state of the construction elevator corresponds to the position of each of the assigned shaft door clearances 5.1.1-5.1.6 in a first shaft wall 5.1 of the second elevator shaft 5. In the region of the construction elevator, these access openings 20.3.1-20.3.7 can be closed with shaft doors 20.4.1-20.4.7 fastened to the construction elevator frame 20.1. Furthermore, a construction elevator car 20.2 which is guided and movable along guide rails and which is equipped with at least one first car door 20.2.1 is integrated into the construction elevator frame 20.1. For moving the construction elevator car 20.2 within the construction elevator frame 20.1, a drive device 20.5 is attached to the construction elevator frame. In FIG. 1, the drive device 20.5 comprises a drive machine 20.5.1 with a drive pulley 20.5.2, wherein the drive pulley carries and drives a suspension cable 20.7 which carries and drives the construction elevator car 20.2 and a counterweight 20.6. The drive device 20.5 could, however, also be present in the form of a cable winch that winds and unwinds a support cable, or in the form of hydraulic cylinders.

[0040] The construction elevator 20 or the construction elevator frame 20.1 of the construction elevator is preferably fixed to the climbing formwork platform 10.1 in such a way that an upper part of the construction elevator frame 20.1 protrudes beyond the climbing formwork platform 10.1 of the climbing formwork device 10, wherein an uppermost access opening 20.3.7 with an associated shaft door 20.4.7 is attached to this upper part, via which the construction personnel can reach the climbing formwork platform 10.1 with the construction elevator 20.

[0041] In an alternative embodiment, the construction elevator 20 can also be fixed completely below the climbing formwork platform 10.1 to the same, such that it does not protrude beyond the climbing formwork platform 10.1 of the climbing formwork device 10. In this embodiment, construction personnel who want to get to the climbing formwork platform 10.1 of the climbing formwork device 10 must use a staircase which spans a floor height H, in addition to the construction elevator 20.

[0042] In order to be able to comfortably reach work sites at all levels in the region of the construction elevator 20, the construction elevator frame 20.1 can have several additional access openings 20.3.2-20.3.5 with associated shaft doors 20.4.2-20.4.5, in addition to the at least two access openings mentioned. At least the lowermost access opening 20.3.1 with its shaft door 20.4.1 can be designed to be vertically displaceable in order to be able to adjust its sill level to the floor level of currently corresponding floors—for example if, as an exception, a floor with a different floor height is built between floors with a uniform floor height.

[0043] The construction elevator 20 is attached to the climbing formwork platform 10.1, such that it always remains positioned in the currently uppermost region of its elevator shaft 5 during the entire construction phase of the building 2, without a hoisting device for lifting the construction elevator being required in the building 2. The construction elevator 20 is fixed in the vertical direction on the climbing formwork platform 10.1, such that the sill levels of its access openings 20.3.1-20.3.6 match the corresponding floor levels 8.X+1-8.X+6 when the climbing formwork device 10 remains in a locking position after a hoisting process. In each of these positions, concrete is introduced between the formwork walls 10.2 in order to raise the walls of the building core 3 by a further section. To ensure that the sill levels of the access openings 20.3.1-20.3.7 and the corresponding floor levels 8.X+1-8.X+7 match during the concreting process, the climbing formwork device 10 with the formwork walls 10.2 attached to it and with the construction elevator 20 must be raised by an entire floor height H between each concreting process. In other words, the walls of the building core 3 must be raised by a section corresponding to an entire floor height H with each concreting process. In addition, the vertical distances between the access openings of the construction elevator must also correspond to the floor height H.

[0044] The building 2 can, however, have intermediate floors, the floor height of which deviates from the floor height H of the majority of all floors, such that the climbing formwork device 10 must exceptionally be raised by a distance that deviates from that of the floor height H of the majority of all floors. In order to be able to guarantee the functionality of the construction elevator and thus the entire transport concept in such a situation, the connection between the climbing formwork platform 10.1 and the construction elevator 20 can be designed to be preferably displaceable or adjustable by about one meter. In addition, one or more of the access openings 20.3.1-20.3.7 can be attached to the construction elevator frame 20.1 so as to be vertically displaceable for the same purpose.

[0045] In order to get from one of the lower floors 7.1-7.X to one of the floors 7.X+2-7.X+7 currently in the uppermost region of building 2, the users first travel with the elevator system 15 able to be adjusted to the building height to a floor (according to FIG. 1: currently 7.X+1) wherein the floor level 8.X+1 thereof corresponds to the current floor level of the lowest access opening 20.3.1 of the construction elevator 20. The users then change elevators by walking over the above-mentioned floor to the construction elevator car 20.2 of the construction elevator 20 in order to reach this construction elevator car to also access the currently highest floors 7.X+2-7.X+7 in building 2, and in particular also the climbing formwork platform 10.1 of the climbing formwork device 10. Corresponding elevator trips are of course also possible in the opposite direction.

[0046] In the borderline situation shown in FIG. 1, the floor level 8.X+1 of the floor 7.X+1 is at the limit of what can be reached both for the elevator car 15.5 of the elevator system 15 able to be adjusted to an increasing height of the building, and for the construction elevator car 20.2 of the construction elevator 20, such that transfers using the elevator system 15 and the construction elevator 20 are possible.

[0047] The construction elevator car 20.2 of the construction elevator 20 can have a first car door 20.2.1 oriented towards the first shaft wall 5.1 with the shaft door clearances 5.1.1-5.1.6 and a second car door 20.2.2 arranged in another wall of the construction elevator car orientated toward a second shaft wall 5.2, wherein at least one access opening 20.3.8 corresponding to the second car door 20.2.2, with a shaft door 20.4.8, is attached to the construction elevator frame 20.1, and wherein, below the access opening 20.3.8 of the construction elevator 20 corresponding to the second car door 20.2.2, a walkable platform 20.8 is attached to the construction elevator frame 20.1, which enables a user of the construction elevator to get from the construction elevator car 20.2 to the interior of the second elevator shaft 5 in order to carry out work there. Such walkable platforms 20.8 are preferably attached at the level of several of the access openings 20.3.1-20.3.6 of the construction elevator frame 20.1.

[0048] In order to make the transfer process from the elevator system 15 able to be adjusted to the building height to the construction elevator 20 as optimal as possible, information about the current vertical position of the construction elevator 20 fixed on the climbing formwork platform 10.1 is transmitted to a controller 15.12 of the elevator system 15 which is able to be adjusted to the building height. This information is used by the mentioned control to determine the target position of the elevator car 15.5 of the elevator system 15 able to be adjusted to the building height, for a transfer stop, which expediently takes place in the region of the lowest access opening 20.3.1 of the construction elevator 20.

[0049] Above the construction elevator 20, the construction elevator frame 20.1 of the construction elevator 20 protruding beyond the climbing formwork platform 10.1 of the climbing formwork device 10 is provided with an impact-resistant protective hood 20.9, which is preferably watertight and sealed against the climbing formwork platform 10.1. This ensures, on the one hand, that the entire construction elevator 20 cannot be damaged by falling objects, and on the other hand the protective hood sealed against the climbing formwork platform 10.1 prevents rainwater from penetrating both into the construction elevator 20 and into the elevator shaft 5 assigned to the construction elevator. If the construction elevator is arranged below the climbing formwork platform 10.1, a protective platform can be attached directly to the climbing formwork platform to protect the components of the construction elevator from falling objects originating from the construction operation.

[0050] In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
