Description

 The invention relates to the field of construction, in particular to mounting devices for attaching a protective apron and sealing holes in a protective apron for anchor releases when performing rolled roofs of residential, public and industrial buildings.

 There is a knot for attaching a protective apron and passing anchor outlets through a protective apron (Details of roofs of residential buildings. Issue 2. Prefabricated reinforced concrete attic roofs with roll-up and roll-off roofs. M., Central Research Institute of Housing, 1979, 60 sec.), In which roof crutches are fixed to the upper part of the wall by shooting them with dowels, and then a protective apron made of galvanized steel roofing is installed on them. Anchor releases are passed through a protective apron through the cut openings.

 A disadvantage of the known assembly unit for securing the protective apron and skipping the anchor outlets is the insufficiently strong fixing of the roofing crutches to the wall, which under the influence of wind loads quickly lose their fastening strength, as a result, the protective apron is deformed and loses its protective properties. In addition, rainwater penetrates through the passage points of the anchor outlets through the protective apron and enters the wall and under the waterproofing layers of the roof.

 The purpose of the invention is to improve the quality, increase the reliability of the known site of attachment of the protective apron and increase the durability of the rolled roofs at the junction with the protruding walls.

 This goal is achieved by the fact that in the unit for attaching the protective apron and sealing the holes for the anchor outlets, including roof crutches, the roof crutches are mounted on the anchor outlets embedded in the outer walls, and the protective apron is pressed down with nuts, and the holes in it for the anchor outlets are sealed with gaskets , washers and mastic.

 The drawing shows the mounting unit of the protective apron and sealing holes for anchor releases.

 In the outer walls 1 laid anchor releases 2 with a pitch of 600 mm. The main 3 and additional 4 waterproofing layers of the roof, when they are attached, are walled onto the walls to its outer side. Roof crutches 5 are welded to the anchor outlets using electric welding 6. Metal washers 7 and then rubber gaskets are put on the anchor outlets 8. Rubber gaskets and metal washers are put on the anchor outlets 9 on the anchor outlets. Nuts 10 are screwed onto the anchor outlets, which provide for pressing the rubber gaskets and sealing the holes 11 in the protective apron. 12 protruding racks 13 are welded to the protruding part of the anchor releases by electric welding. The places of the passage of the anchor releases through the protective apron are sealed with sealing mastic 14.

In the outer walls 1 below the abutment mark of the reinforced concrete slabs of coatings 15, when masonry is carried out, the anchor outlets 2 of steel ⌀ 18 mm, class A-1, length 650 ... 700 mm with a bend of 90 ^o in the lower part and with cutting the upper part to a length of 80 mm. In the case of external walls made of lightweight concrete panels 1, anchor outlets are installed during the manufacture of the panels. After the installation of the main waterproofing 3 and three additional 4 layers of the roof, which lead to the outer edge of the wall, roof crutches 5 are installed from a metal strip 40 x 40 mm with a pitch of 600 mm. Crutches are pre-galvanized in the factory. On crutches, on one side, a cutout with a radius of 10 mm is machined at the factory. Pressing crutches against the wall and anchor outlets, they are welded using electric welding 6. Metal washers 7 are put on the upper part of the anchors and then rubber washers 8 in accordance with GOST 5.1011-71. In a protective apron 9 made of galvanized steel roofing δ = 0.8 mm GOST 8075-56, holes with a diameter of 20 mm are precisely marked and drilled, after which the protective apron is mounted on the wall. From above, rubber gaskets 8, metal washers 7 are put on the anchor outlets and then the nuts 10 are screwed on, tightly pressing the washers to the protective apron. All metal products (washers, nuts) are pre-galvanized. The remaining free upper part of the anchor outlets is welded by means of electric arc welding of the guard post 13 of metal ⌀ 18 mm of class A-1 with a length of 430 mm. The places of welding of racks with anchor outlets are painted with an anticorrosive composition, and the joints of the metal washer 7 and the rubber gasket 8 are coated with sealing mastic 14 according to GOST 14791-69.

 Welding roof crutches with anchor outlets allows you to firmly and reliably fix them to the wall, which is an important factor that increases the service life of rolled roofs. The implementation of a tight joint in a protective apron eliminates the penetration of water through the protective apron on the wall and in the roofing carpet, which also increases the durability of rolled roofs. Thus, the use of the claimed invention allows not less than 3 times to increase the service life of rolled roofs in places where they adjoin the protruding walls.
