DETAILED DESCRIPTION

Example 1

[0026] An exemplary construction of component composed steel structure for lifting equipment is described in FIG. 1 to 11.

[0027] As described in FIG. 1, the construction design consists of closed steel profiles; these main construction components are batch manufactured in steel industry. Frontal pillars 1 and back pillars 2 as well as side crossbeams 3 and back crossbeams 4 are made of the same closed profile types, the lengths of individual components are tailored to dimensions of the lifting technology and the shaft area. FIG. 2 to 4 describe the back angular set 7, where the back pillars 2 are connected with side crossbeams 3 and back crossbeams 4 via connecting components composed of a set of identical mirror-inverted angular joints 16 from bent metal sheets and a set of identical mirror-inverted L-joints 17 from bent metal sheets.

[0028] The back pillars 2, side crossbeams 3 and back crossbeams 4 are equipped with threaded joints 18 consisting of the screw 30, anti-release washer 31 and threads 19 tapped into the construction profile that use sets of identical mirror-inverted angular joints 16 from bent metal sheets and sets of identical mirror-inverted L-joints 17 from bent metal sheets to secure a firm and extra resistant connection of side crossbeams 3 and back crossbeams 4 with back pillars 2. At the back part of the construction, there are side crossbeams 3 at 900 angle position from back crossbeams 4 at each level, where these adjacent components are linked together using sets of identical mirror-inverted angular joints 16 from bent metal sheets and sets of identical mirror-inverted L-joints 17 from bent metal sheets to secure the exact right angle between the adjacent horizontal components when threaded joints 18 are tightened properly.

[0029] FIG. 5 to 7 represent the frontal T-set 8, where the side crossbeams 3 are connected to frontal pillars 1 at the front part of the construction with connections consist of bent L-joint 22 and bent space joint 23. The frontal pillars 1 and side crossbeams 3 are equipped with threaded joints 18 consisting of the screw 30, anti-release washer 31 and threads 19 tapped into the construction profile that use sets of bent space joints 23 and bent L-joints 22 from bent metal sheets to secure a firm T-joint between side crossbeams 3 and frontal pillars 1 at the front part of the construction.

[0030] The threaded joint system 18 for all threaded joints of the construction is identical except joints for carrying pillars.

[0031] The frontal pillars 1 and back pillars 2 in the columnar support 6, as described in FIG. 8 to 11 are mutually affected only by pressure, which guarantees a high carrying capacity even of higher constructions. Individual vertical components that constitute the frontal pillars 1 or back pillars 2 are linked together with columnar joints 20 from bent metal sheets to stabilize the mutual position of linked vertical components. In addition, the columnar joints 20 are secured by the set of identical mirror-inverted angular joints 16 from bent metal sheets as well as a set of identical mirror-inverted L-joints 17 from bent metal sheets at the back part of the construction and bent space joints 23 as well as bent L-joints 22 at front part of the construction. The columnar joint 20 presented in FIGS. 9 and 11 is equipped with pressed nuts 21 positioned at the columnar joint 20 at 900 angle. The endings of linked vertical components of frontal pillars 1 and back pillars 2 contain a set of holes 33 presented in FIG. 7 that are used to tighten screws 30 with fixing washers 31 to pressed nuts 21 positioned at columnar joints 20. When tightening screws 30 the positions of linked components are arranged and fixed. The columnar joints 20 are installed inside the angular back set 7 and front T-set 8 of the horizontal part of the construction, which eliminates the visible linking components between crossbeams.

[0032] At front part of the constructions there are frontal pillars 1 connected through small bent L-joints 15 of frontal profiles to frontal crossbeams 5 using threaded joints 18 to anchor shaft doors and specify the shaft geometry. The flat L-joints 26 with threaded joints 18 are used to fasten closed gantry profiles 24 that constitute the construction portal.

[0033] In side crossbeams 3 and frontal crossbeams 5 there are grooves 14 to fasten the shaft door anchors and holes 12 for self-tapping screws 32 that tighten anchors 11 used for the construction jacketing.

[0034] In frontal construction columns 1 there are sliding anchors 10 fastened using a sliding bent joint 27 and sliding plate 28 to attach the whole shaft construction through threaded rod 29 and a chemical anchor to walled or concrete constructions of the object next to the shaft itself.

[0035] The advantage of the proposed solution is an easy and accurate machine production without welding processes that eliminates human factor faults as much as possible.

[0036] The described solution of self-supporting component assembly construction shaft, with respect to practical experiences with designing and implementation of lifting technologies, deals comprehensively with drawbacks of existing commonly used welding processes and allows a batch production of unified main carrying components and a batch production of joints regardless the construction dimensions. It smoothens the assembly process because the two tools are no longer necessary to tighten the threaded joints. The proposal retains the stability and carrying capacity of the construction while no additional stabilizing components are necessary; in general, it simplifies the construction manufacturing and welding process, metal sheets cutting and bending for production of horizontal as well as vertical carrying components of the construction.

[0037] The construction assembly does not require any specialized installation team; after being trained, the construction installation can be performed by installation workers responsible for the assembly of the lifting technology, so it is not necessary to coordinate several teams on the construction site.

[0038] For joints the unified screws are used to prevent any confusion or faults during the installation. The threads are mounted directly into components, so it is not necessary to use two tools when holding and tightening individual joints.

Example 2

[0039] It is based on the example 1 wherein the set of identical mirror-inverted angular joints 16 and the set of identical mirror-inverted L-joints 17 are not bent but welded.

INDUSTRIAL APPLICABILITY

[0040] The component composed steel structure for lifting equipment according to the invention can be manufactured repeatedly and used for installations of any exterior or interior shaft technologies with respect to the requirements of maximum quality, durability and stability.
