Description

The invention relates to construction and can be used in the installation of composite cladding structures, mainly elements of the "paintings" of the metal seam roof, for their fastening on the supporting base of building structures, as well as in the reconstruction of roofs.

A well-known device for attaching composite cladding structures of "paintings" of metal roofs is a lathing or continuous flooring on which clasps are fixed with nails or a self-tapping screw, fixed at the joints of panels of cladding structures of "paintings" (see Tin and carpentry. Training course series, N .L. Podgorny, Rostov n / A: Phoenix, 2000 .-- 224 p., For 68 p.).

The disadvantage of such a structural implementation of the fastening of the cladding is the complexity and high cost of the structure, the high complexity of the work on the manufacture and installation of the crate or flooring, the high consumption of material for the arrangement of the crate.

A known attachment site of non-metallic facing wall panels containing elements with threaded connections fixed to the dowel (anchor) by means of a fixing element, part of which is located inside the dowel, ensuring the fixing of the fixing element relative to the dowel. (DE 1683207 A. 07/01/1971, class E 04 F 13/08, 5 pp.).

This mount does not allow for water permeability and tightness of the mount of the composite cladding structures in the place of their docking with each other.

The closest in technical essence (prototype) to the proposed invention is the attachment point of composite cladding structures containing a dowel, part of which is fixed inside the tubular element, and the other is located inside the insulation material located between the cladding and the supporting base of the building structure, the tubular element itself it is complete with the possibility of fixing on the supporting base of the building structure (FR 2830556 A1.11.04.2003, class E 04 F 13/08, 10 pp.).

The disadvantage of this mount is the permeability and leakage of the joints at the junction of the cladding structures, which excludes the possibility of using this site in the elements of the roof, especially when mechanical impacts on the roof, for example, from the environment.

The technical result achieved by the implementation of the present invention consists in the possibility of a significant simplification of the design, rejection of the crate (wooden or metal), simplification of the installation process of composite cladding panels "paintings", while ensuring the necessary tightness, water permeability, strength and rigidity of the fastening, corresponding to current SNiPs , as well as in reducing noise during vibration due to mechanical stress.

The specified technical result is ensured by the proposed design of the mounting unit for composite cladding structures containing a clamp and a dowel with a fastener in which the clammer mounted on the dowel is sealed in the joint of the facing cladding structures and is folded to form a seam connection.

The invention is illustrated in the drawings.

Figure 1 shows the attachment point of composite cladding structures, in particular, "paintings" of metal folded roofs, where 1 is a dowel with an extension 5 intended for fastening insulation material, 2 is a tubular element, 3 is a clamp for connecting composite cladding structures (not shown ), 4 - a fixing element connecting the clamp to the dowel, 6 - a gasket of heat-insulating material, 7 - a fastener, 8 - an elastic insert in the form of, for example, a coil spring, 9 - the bearing surface of the building structure - armament of.

Figure 2 presents a variant of the mount with the implementation of the fastening element 7, in the form of a T-shaped bolt placed with its T-shape inside the tubular element 2.

A fastening assembly comprising a dowel 1 with extension 5, designed to fasten insulation material (or mats, etc.) to the building structure 9, is connected to the clamp 3 by the upper part included in the joint of the facing structures of the “paintings” and after manually or mechanically folding providing a tight tight waterproof connection.

In the particular case of using the fixing element 4, one or several gaskets 6 can be placed under the head (cap), including from heat-insulating material

The dowel 1 can be attached to the building structure 9 directly (for example, entering a pre-drilled or punched hole in the building structure 9, expanding with the fixing element 4, or screwing (fixing) the fixing element 4 to the building structure 9, or indirectly, entering and expanding inside the tubular element 2 (if the surface of the building structure is made, for example, of steel 1-10 mm thick).

To increase the reliability of the fastening carried out through the tubular element, the inner surface of the tubular element 2 may be deformed or have an increased roughness. The tubular element 2 can be metallic or non-metallic and can be attached directly to the building structure 9 by welding, soldering, gluing, or otherwise.

In some cases, to increase the elasticity of the structure and its durability, for example, from the effects of various types of static and dynamic loads, the tubular element 2 can be attached to the building structure 9 not directly, but through an elastic insert 8, which can be made, for example, in the form of internal or external springs attached by welding, soldering, gluing or otherwise to the building structure 9 and to the tubular element 2.

In the particular case, the elastic insert 8 can be attached to the fastening element 7, which is fixed on the building structure 9.

The embodiment of the fastening element 7 may be any from a tube to a plate or a combination thereof.

The fastener 7 itself is fixed to the surface of the building structure 9 by soldering, welding, gluing, mechanically using nails, rivets, screws, bolts, screws, anchors, etc.

In order to reduce the cost of the design of the attachment point, the elastic insert can be made in the form of a rod with expansion, for example, a bolt with a head (Fig. 2), its expansion enters the tubular element 2, and the lower part is pressed into the tubular element 2, soldered, glued, and fixed mechanically way, this ensures the mobility of the connection, but excludes the possibility of its undocking at the mount.

The dowel 1 before molding the seam connection and fixing on its expanding part of the insulation material (not shown) is attached to the bearing surface of the building structure-structure 9 using fasteners 7.

In the particular case of the implementation of the attachment point, the element 4 fixing the lower part of the clamp 3 on the extension 5 of the expansion bolt shield 1 is made in the form of a screw, between the head of the clamp and the surface of the clamp 2 adjacent to the surface of the expansion bolt shield 1, a gasket 6 made of heat-insulating material can be located.

In the particular case of the implementation of the attachment point, the expansion of the dowel 5 can be used as a clamping disk for attaching insulation material to the building structure 9

In the particular case of the assembly of the fastening of the composite cladding structures, before folding the joints of the clammer 3 with the cladding panels, the dowel 1 is fixed to the bearing surface of the building structure-structure 9 through the fastener 7 connected to the tubular element 2 into which the dowel 1 is placed.

In the particular case, the clamp 3 can be mounted on the expansion bolt shield 1 with the extension 5 from the bottom (in this case, a hole is made in the clamp 3 through which the expansion bolt shield 1 is inserted and the clamp is between the lower surface of the expansion 5 of the expansion bolt shield 1 and insulation material

With this arrangement of the clamp, the extension 5 of the dowel 1 can be cut to reduce size and ease of installation.

The length of the tubular element 2 should be such that the distance from the contact surface of the expanding part of the dowel 5 with the protruding part of the clammer 3 to the bearing surface of the building structure-structure 9 was less than or equal to the thickness of the insulation material.

In the particular case, the tubular element 2 of the attachment site can be made of metal, and the clamp 3 of the attachment site from the material of the facing structure.

In the particular case of the implementation of the mount, the facing structures are made in the form of a sheet metal roof.

When installing composite cladding structures, the proposed design of the mount is used as follows.

Insulating material in the form of sheets or mats (not shown) that are fixed on this base with a dowel 1 passing through this material is laid on the supporting base of the building structure-structure 9. The dowel 1 itself is attached to the base of the building structure-structure 9 a) directly using fasteners 7, and in the particular case, b) through the tubular element 2 with the possible use of an elastic insert 8 inserted inside it (Fig. 1) or a T-shaped bolt ( figure 2), while the tubular element 2 is fixed on the bearing surface of the building structure-structure 9 through the fastening element 7.

When metal sheets are used as cladding panels, their seam connection with the clamp 3 installed in the junction of the sheets provides reliable fastening of the panels relative to the surface of the building structure-structure 9.

Dowels, which are usually made of materials with low thermal conductivity, provide good thermal insulation between the joined cladding panels and the building structure, and in the particular case between the cladding panels and the tubular element 2, which eliminates the possibility of forming cold bridges, the presence of which leads to condensation moisture on the surfaces of the building structure when cooling the outer surface of the cladding materials.

Using the proposed fastener allows you to increase the life of the composite cladding, including roofing, reduce the cost of installation and at the same time provide the composite cladding with the necessary rigidity, for example, as for industrial roofs. The composite cladding becomes significantly less noisy due to a decrease in the amplitude of vibrations due to mechanical stress and the presence of insulation material between the panel and the bearing surface of the building structure-structure 9.

The proposed mounting unit of composite cladding structures can be used both for the installation of composite cladding structures on the bearing base of building structures, as well as for the reconstruction of composite cladding structures.

Installation of composite cladding structures using the proposed fastener is simple and less time-consuming than previously known, especially in the construction of large complexes, such as, for example, sports facilities.
