Description

(1) The present invention will be described hereinafter according to a preferred embodiment example thereof, provided by way of example and not for limitative purposes with reference to the enclosed drawings wherein:

(2) FIG. 1 shows an axonometric view of a complex frame resulting from assembling several module frames of the structure according to the present invention, wherein the mentioned dimensions represent purely indicative and not limiting values;

(3) FIG. 2 shows an axonometric view of an assembling knot for the connection of the module frames;

(4) FIG. 2A shows the sectioned previous view;

(5) FIGS. 3, 4, 5 and 6 show axonometric views in partial section illustrating in detail different assembling shapes at a knot of the complex frame in the structure according to the present invention; and

(6) FIGS. 7 and 8 show views of complex buildings which can be obtained with the structure according to the present invention.

(7) By referring to the figures, a complex frame of a modular building structure is designated with 1; it is constituted by a certain number of module frames which have a substantially parallelepiped-like shape and are identified by the longitudinal beams 2, the vertical beams 3 and the transversal beams 4.

(8) Under parallelepiped, generally a straight parallelepiped with rectangular faces is meant.

(9) In the described version, each module frame, designated with 10, has sizes allowing it to fall within the shape of a container which can be transported by ordinary route, in case loaded on the platform of an articulated vehicle, without requiring a special transportation to move it from the assembly site to the production site. A building module 50 then will correspond to each module frame, the building module comprising the related claddings, the floors (ceiling, floor), the inner structure, the electric and water services and so on and it could be useful to assemble a complex building 100 (FIGS. 7 and 8) with different sizes.

(10) Each module frame 10 then has angles wherein the longitudinal, vertical and transversal beams join. At such angles, the complex frame 1 comprises a plurality of connecting knots 5 joining module frames 10 adjacent laterally on the same horizontal or vertical plane, the lower side or upper side on staggered planes, or providing for the connection of the module frames 10 to a suitably arranged flat basement, or to a not represented roof structure.

(11) In case of adjacent module frames 10, they could be faced at a longitudinal, vertical, upper or lower wall; otherwise, in case of frames on staggered planes, they will have in common an edge with two beams of the same type faced one onto the other one.

(12) Therefore, the shapes of each knot 5 change according to the knot position, in particular each knot 5 should be capable of providing for the mutual connection of a number of module frame varying from one to eight and thereof with basement.

(13) However, each knot has features common to all shapes which identify it, and which will be detailed hereinafter.

(14) In particular, the knot 5 has a box-like structure with an inner core 6 shaped like a hollow straight parallelepiped, formed by six walls facing two by two. Each wall has a circular opening 7, delimited by a ring 8.

(15) Preferably the core 6 has cubic shape. The openings 7 on the faces thereof form respective channels opened according to orthogonal axes X, Y and Z. Such channels are opened, and the core inner portion provides a space for passing through a channel or from a channel to the other one.

(16) The core could be made of a suitable material, for example steel, preferably in one single piece and with adequate thicknesses, so as to have the required resistance to any design stress.

(17) At each opening 7, the core 6 comprises a corresponding supporting plate 9, for a total of six supporting plates, parallel or orthogonal therebetween two by two; in particular, the plates 9 of openings 7 one in front of the other one are parallel therebetween, and the plates 9 of openings 7 on adjacent plates are orthogonal therebetween.

(18) Even the supporting plates could be made of suitable material, in case in one single piece with the core 6, or by means of welding of pieces.

(19) Each supporting plate 9, if it extends beyond the plane defined by an adjacent plate 9, defines therewith an angular or side rest for a module frame angle 10.

(20) By referring to FIG. 2, on each angle of the core 6 the plates 9 extend beyond the two adjacent plates and viceversa, and then, at each one of said angles, the knot has an angular rest 11 formed by three supporting plates 9 forming an angular space with the three resting walls.

(21) By referring to FIG. 4, at an edge of the core 6 two supporting plates 9 extend one beyond the other one and viceversa, by forming a side rest 12 formed by two L-like positioned plate ends.

(22) It is to be noted that, at each rest formed thereby, the supporting plates 9 comprise a plurality of through holes apt to be engaged by respective boltings 14 for fastening with the module frames 10.

(23) In case a supporting plate 9 is not crossed by any of the adjacent plates, it forms a resting plane 15 which can be connected to a basement or a roof (FIG. 6).

(24) The shape of the knots 5 then allows not only to connect adjacent module frames 10, but to space apart them one from the other one. This determines two substantially combined effects: 1. the overall sizes of the complex frame obtained by assembling module frames will be larger than the sum of the sizes of the single module frames; and 2. the distance between each module frame could allow, together with the presence of the above-mentioned channels in each knot 5, to arrange easily through plants of electric, water nature (mains water, which water, waste water, heating, refrigeration), air conditioning plants, service tubes, alarm plants and so on.

(25) The first one of said effects allows to make each pre-assembled module 50 capable of being transported in a simple way, as a usual container, and then to obtain a building the overall sizes thereof would not be otherwise compatible with normal transportation systems.

(26) To this regard, the previously described angular rests will be useful to receive the angles of each module frame 10. Each angle will include a connecting element 16 of box-like type, formed by two or three walls connected therebetween, which will be in contact with the respective rest. The connecting elements 16 will be useful to join therebetween the beams 2, 3, 4 of the frame module 10.

(27) Advantageously, these beams have a L-like section with the inner angle facing towards the inner space of the module frame 10. In this way, they could be useful to receive the edges of panels 17 which will form the floors or partitions inside the assembled building, or connecting elements between adjacent panels.

(28) The L-like beams, as well as the connecting elements 16, could be made of suitable material, for example a folded or forged steel plate, or obtained by welding.

(29) The above-described structure obtained by assembling the knots 5 with the module frames 10 further allows to obtain an adequate resistance to earthquake motions according to the existing rules.

(30) Each module frame 10 could include elements for reinforcing the structure thereof. In particular, the section of the beams 2, 3, 4 could be of box-like type; the beams could be connected by vertical struts arranged on the vertical faces, or angular brace assemblies or additional diagonal beams, or even transversal currents on any face.

(31) It is to be noted that each module 50, although formed by a frame which repeats from module to module, could assume very different shapes. In particular, it could include outer claddings which could be adapted to the climatic area of interest, or inner partitions, or even windows with wide sizes or walls with pre-assembled windows, or at last empty spaces for creating unique environments extending on several modules.

(32) Advantageously, the longitudinal sizes of the frame module could be equal to the sum of a finite number N of cross sizes of N1 knots: typically the longitudinal size could be equal to that of two module frames arranged transversally plus an intermediate knot

(33) This allows to assemble different module frames by changing the orientation thereof within the same complex frame, thus by obtaining an even greater freedom in assembling the different modules.

(34) Furthermore, they could be arranged to obtain terraces, or wide inner spaces surrounded by modules and so on, by using the modules as if they were bricks to create any shape.

(35) At the outer surface of the complex frame 1, the rests prearranged by the knots 5 could receive respective stopper-like elements 18, for closing the opening 7 facing outwards, and framework elements 19 extending from a knot to the other one and which will be useful to support a cladding panel 20.

(36) In this way, on the same outer wall, each so-obtained framework could provide a different cladding, so as to obtain different compositions.

(37) It is to be noted that the above-mentioned stopper-like elements and the framework elements have the task, together with the panels 20, to close the outer surfaces of the building, but even to implement a seal preventing the air from entering the intermediate spaces between the module frames 10, acting as thermal and acoustic insulation and even for fireproofing purposes.

(38) Such seal can be implemented thanks to self-expanding belts and gaskets, arranged on the edges of the stopper-like elements and of the framework elements.

(39) The above-described components will be treated to have fireproofing, anti-intumescent features and to be protected from corrosion.

(40) To the above-described a person skilled in the art, in order to satisfy additional and contingent needs, could introduce several additional modifications and variants, all however comprised within the protection scope of the present invention, as defined by the enclosed claims.
