Description

Contact demountable contact of wall elements

Field of technology

The invention relates to a contact demountable contact of the wall parts of building structures in a modular design of a vertical structure provided with connecting elements with the possibility of disassembling and reassembling them elsewhere. It is therefore a so-called dry screw connection without grouting concrete or without welding, allowing easy assembly, disassembly and relocation and reassembly.

Prior art

There are currently several ways and embodiments of dry detachable vertical joints of wall panels. Mostly these joints or joints are solved on the principle of mechanical joints, self-rectifying or locking joints, special foams, locks or. shaping of elements that usually show insufficient shear strength and load-bearing capacity and are not able to fulfill a static function and mainly ensure, ie fix the mutual position of adjacent wall members, eg CD-20, IFD systems - "El Povori", NEXT 21.

Mostly, solutions are used in practice that do not allow easy disassembly without damaging the connected parts. To profiled or. smooth vertical grooves formed between the faces of the joined, jointed wall sections, a concrete or cement grout is usually placed, possibly supplemented by reinforcement distributed continuously along the height of the groove, or discreetly at both ends of the groove. Such an embodiment is laborious and involves wet processes or welding of reinforcement, and its main disadvantage is the very difficult disassembly of such connected parts.

The essence of the invention

Said disadvantages are largely eliminated by the contact demountable contact of the wall panels with the possibility of its disassembly and reassembly at another place, according to the present invention. Its essence is that one wall panel is provided with at least one plate with a through hole with an internal thread and the other wall panel is provided with at least one corresponding plate with a hole with an internal thread. A hollow expansion screw is located in the internal thread of one plate of one wall panel, through which a pressure screw passes, which engages with the internal thread of the corresponding plate of the other wall panel.

The internal threads are preferably formed by a nut welded to the plates. In a preferred embodiment, the boards are provided with at least two anchoring elements located in the material of the wall panels. And, in a preferred embodiment, the plate of the second wall panel is provided on its side facing the material of the second wall panel with a metal box to create a space in the second wall panel for collision-free insertion of the hollow expansion screw and the pressure screw.

The contact surface between the hollow expansion screw and the built-in plate is preferably provided with a surface treatment to increase the mutual friction of the expansion screw and the plate.

The proposed solution of joining adjacent wall panels allows easy assembly, disassembly and reassembly without the use of wet processes and welded joints without any failure of the joints. The insertion of a contact bidirectional screw connection enables the connection of the components at the point of their mutual contact, while the number of screw connections can be adjusted along the height of the contact of the connected wall components. The proposed solution provides a discrete connection of adjacent wall panels, which ensures the transfer of vertical shear forces acting between the wall panels, shear forces acting perpendicular to the wall panels and normal

- 1 CZ 306568 B6 forces acting in the plane of the wall panels and thus decisively participates in the creation of a wall element formed - composed of individual wall panels. The screw connection solution of the wall panels according to the invention consists of several, but at least one two-stage screw connection with mutually opposite screws formed by a pair of special connecting elements built into the vertical contact surfaces of adjacent wall panels interconnected by a spreading and tightening element. The shear strength of the contact can be adjusted by a prestressing pressure screw and by adjusting the contact surface between the face of the hollow expansion screw and the steel plate.

Explanation of drawings

The invention will be elucidated in more detail on the basis of a specific exemplary embodiment with the aid of the accompanying drawings, in which FIG. 1 shows an exemplary connection of wall panels in a side view. Fig. 2 shows this connection in an exploded axonometric view, and Fig. 3 shows another exemplary connection of the wall panels in a side view.

Examples of embodiments of the invention

Fig. 1 shows the connection of adjacent wall panels 1, 2. One wall panel 1 is provided in the area of the contact surfaces with a steel plate 3 with an opening 4 and with a welded nut with an internal thread 5. The other wall panel 2 is provided with a steel corresponding plate 6 with hole 7 and welded nut with internal thread 8 for screwing in the hollow expansion screw 9. The hollow expansion screw 9 makes contact between the faces, i.e. the steel plates 3 and 6 of the adjacent wall parts 1 and 2 are screwed into the nut with internal thread 8 so to define the required distance gap by resting on the built-in steel plate 3 of the opposite wall panel 1. A connecting prestressing-pressure screw 11 connected to the internal thread 5 of the nut connected to the steel plate 3 built into the opposite plate is threaded through the hole 10 of the hollow expansion screw 9. wall panel £. The connecting pressure screw 11 provides the required pressure preload of the contact of the expansion screw 9 and the steel plate 3. The steel plate 6 is provided with a sheet metal box 12 creating a space in the wall panel 2 for collision-free insertion of the hollow expansion screw 9 and the connecting prestressing pressure screw 11. Steel plates 3 and 6 are provided with anchoring elements 13.

Fig. 2 shows the individual parts of the invention in an exploded state. In Fig. 3, the solution is supplemented by a washer 14 and a circlip 15.

Industrial applicability

The contact demountable contact of the wall elements according to the invention finds use in the construction of temporary and permanent buildings.
