Abstract

The skeletal structure consists of prefabricated structures concrete building elements. Wireframe in one direction of the building body are rigid frames consisting of of vertical supports (2) and beams (3) that they serve as a support for ceiling slabs (4). In the second direction the skeleton structure is placed one above the other approximately square support elements (5) having a height floors and are either framed or full-area the walls. These support elements (5) provide support for horizontal beams (3). Buildings can be used with this skeletal structures build up very quickly. inside construction can be completed in many variants in use non-bearing elements.

Description

The invention relates to a skeleton building body for multi-storey buildings using prefabricated building elements.

BACKGROUND OF THE INVENTION

Conventional multi-storey skeleton structures using welded steel fittings or on-site concrete frames are associated with relatively high costs. On the other hand, wood frame structures could not be enforced due to resistance to light constructions, for static reasons and also to the risk of fire, especially in multi-storey buildings.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a skeleton building structure which will have the advantages of heavy structures and yet allow the cladding to be provided with non-load-bearing panels that are common in lightweight structures.

SUMMARY OF THE INVENTION

The problem is solved and the drawbacks of the known solutions are largely eliminated by a prefabricated multi-storey building body using prefabricated building elements according to the invention, which consists in that each floor consists of a series of side by side frames of prefabricated building elements on mounted prefabricated ceiling slabs, the frames consisting of vertical supports and horizontal beams which are interconnected by steel inserts and concrete grout into a solid body and in the remaining direction of the skeletal building body there are frame or solid support elements whose vertical dimension corresponds to the height of the floor and are fitted with lateral support elements for receiving beams.

It is preferred that the horizontal beams are provided with concrete grouting at the vertical support points.

Furthermore, it is advantageous if the support elements are provided on both sides with recesses for receiving horizontal beams which are formed below the level of the upper side of the support element.

Said support elements are preferably provided on both sides on the inside of the building body with protruding support strips, which are provided with shoulders and are integrally formed with the support elements.

Finally, it is advantageous if the vertical supports are equipped with steel inserts projecting at the point of connection with the horizontal beams.

Such a skeleton body can be produced very quickly and rationally and allows for a variety of alternative ones during construction. adjustments.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS The invention is illustrated by the following non-limiting examples, which are described in the accompanying drawings, in which:

FIG. 1 is a perspective view of a skeleton building body; FIG. 2 side view of the frame support body,

FIG. 3 shows a vertical section through the connection of the supports and the ceiling slabs.

DETAILED DESCRIPTION OF THE INVENTION

The multi-storey skeleton building body according to FIG. 1, for example for residential buildings, comprises on the floor in one direction side-by-side frames 1 which consist of prefabricated vertical supports 2 and beams 3. The vertical supports 2 and beams 3 are mutually supported by steel inserts 13 and concrete grouts 15 - see FIG. Fig. 3 - connected to a rigid, self-enclosed frame 1. They are mutually self-supporting and a plurality of such frames 1 can be placed one above the other. On these frames 1, prefabricated ceiling slabs 4 are laid. cavities filled with rigid foam and only be provided with longitudinal reinforcements.

In a further direction of the skeleton building body, i.e. in the direction perpendicular to the frame 1, there are prefabricated support elements 5 made of concrete and the like, which are designed as one-piece structural elements having substantially square shape and height corresponding to the height of the floor. central opening 11 - see FIG. Fig. 2. In an alternative embodiment these support elements 5 can also be designed as full-surface walls. The support elements 5 are provided with offset shoulder 6 for receiving the beams 3. ·

FIG. 2 it is clear that the support elements 5 are provided with a pair of laterally positioned vertical support rails 7, the thickness of which is greater than the thickness of the support elements 5. The upper sides of these support rails 7 form recesses 6 for receiving the supports 2. The height of the beams 2 is lower than the upper side 8 of the support element 5. On the outside of the building, the supporting strips 7 extend in the plane of the wall, while on the inside of the building these supporting strips 2 project. The width of the supporting elements 5 is chosen such that the supporting elements at least approximately correspond to the usual width of the corridors in the building. The staircases 2 between the floors are also adapted to the height of the floor and are preferably one-piece.

The length of the vertical supports 2 corresponds to FIG. 3 and the vertical supports 2 are arranged one above the other in the vertical direction. Said vertical supports 2 are preferably made of concrete with a steel insert 13. that protrudes from their upper side. The horizontal beams 3 are either solid or consist of an upper plate 12 below which a lower plate 14 is arranged parallel to it. The horizontal steel inserts 13 extend into the space between the two plates 12, 14 and the vertical steel inserts 13 ¹ provide the connection between the vertical supports 2 and the beams 3. The space in the area of the vertical supports 2 is covered with concrete grout 15.

The construction of such a self-supporting framework body of the kind described can take place in various ways. For example, the outer wall may be in the form of a two-layer insulating structure. For example, gypsum boards may be used for lining the inner walls.

The described skeleton building body is very rigid in both directions.

The skeleton body of the described embodiment can be assembled extremely quickly and at low cost using prefabricated elements. The skeleton building according to the invention is suitable for multi-storey buildings, for example residential buildings with one or more apartments.
