Description

I

The invention relates to the construction and can be used for butt joints of roof panels.

According to the main auth. St. No. 549557, a butt joint of Chernov’s roofing panels is known, including a seal, a mastic in the joint cavity, edges of the roofing waterproofing coating wound up under mastic, and a protective element, fulfilled in the form of a U-shaped core with openings with their ribs c. mastic flush with the surface of the panels. At the intersections of the longitudinal and transverse seams of the roof, protective caps are fixed, filled with mastic 1.

The reliability of such a joint is insufficient, especially with a considerable width of the joint gap between the panels.

The purpose of the invention is to increase reliability.

This goal is achieved by the fact that in a butt joint of roofing panels a protective element is placed in the joint cavity with its opening on the edges of the panels and additionally provided with peripheral longitudinal ribs, the height of which is equal to the embedment depth for the mastic edges and the waterproofing roof.

The ribs can be made in the form of folds formed from the material of the security element.

FIG. 1 shows a butt joint of panels of full factory readiness, made with heat insulating and waterproofing layers, cross section; on fit. 2 node of the intersection of the longitudinal and transverse joints, axonometric.

The butt joint of panels 1 includes concrete filling the gap 2, edges 3 of the roofing waterproofing coating 4, placed under mastic 5, into which the protective U-profile profile 6 embedded with the openings 7 supported on the edges of the panels is embedded.

The protective profile is additionally provided with peripheral ribs 8. All profiles are made in the form of folds of a metal strip, from which it is made

roar through The joint cavity in the lower part is comforting 9. At the intersections of the joints of the sheet, there are protective caps 10, filled with mastic. The edges of the waterproofing coating are fixed on the bevel of the panels, for example, by gluing. In this case, the bevels can be made gently sloping within the thickness of the layer of insulation 11 and tightening, if present.

In the case of the use of slabs of lightweight concrete or in the absence of a warming layer, bevels for bends and gluing edges

Waterproofing paths are performed directly in the body of the support plate itself, along its edges.

Profile b is installed flush with the roof of the pael, but lies with its wing 7 on the edges of the waterproofing carpet. panels or on the edges of the zastetnogo layer, if any, is provided on the top of the waterproofing coating of the panels.

Protective profiles are embedded in a mastic filling the cavity of the junction in a heated condition.

The invention improves the reliability of the butt joint of roofing panels due to

increase the stiffness of the protective profiles and better seal the joint cavity, prevent the mastic from flowing out during its softening in the summer season.
