Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an inverted waterproof and heat-insulating sloped roof structure. Background Art

[0002] During construction, the roof will be waterproofed. The conventional construction method is to cover the waterproof layer on the insulation layer, while the inverted waterproof insulation is to lay the insulation layer on the waterproof layer to prevent the waterproof layer from being damaged due to thermal expansion and contraction.

[0003] Existing inverted waterproof and thermal insulation slope roof structures are mostly constructed by laying waterproof membrane on the leveling layer, laying a protective layer on the waterproof membrane, and directly laying a whole board of thermal insulation material on the protective layer. The thermal insulation materials are connected by sealing strips, which leads to poor connectivity between the thermal insulation material and the protective layer, and the risk of falling off in windy weather. At the same time, the thermal insulation material is fixed by adhesion and lacks a mechanical fixing foundation. Therefore, a large area of ​​plate-type thermal insulation material is generally selected. When replacing, a large number of floor tiles need to be lifted, which makes it inconvenient to replace the thermal insulation material when it is damaged. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1: This example aims to propose an inverted waterproof and thermal insulation slope roof structure;

[0027] according to Figures 1 to 3 As shown, it includes a slope adjustment layer 1.

[0028] The construction workers first lay the slope leveling layer 1 on the base layer. Before laying, they check whether there are any raised or sunken parts in the base layer. The raised parts are leveled and the sunken parts are filled with cement mortar. After the base layer treatment is completed, the slope leveling layer 1 is laid.

[0029] The slope leveling layer 1 is generally made of: cement hydrophobic expanded perlite or emulsified asphalt hydrophobic expanded perlite, and the slope near the rain gutter is not less than %.

[0030] After the slope layer 1 is laid, the leveling layer 7 is laid on it. The construction workers first clean the upper surface of the maintained slope layer 1, and then lay cement mortar. Then the construction workers use a scraper to level it to ensure that the surface is flat without affecting the slope of the roof, which is convenient for the subsequent laying of waterproof membrane.

[0031] After the maintenance of the leveling layer 7 is completed, the waterproof layer 2 is laid on the leveling layer 7. The waterproof membrane can be made of polymer membrane, coating waterproof material and other materials. The cement is first mixed on site, and the waterproof membrane is cut, and then the waterproof membrane is laid on the leveling layer 7 by wet laying method.

[0032] After the waterproof layer 2 is laid, the protective layer 3 is laid. Fine stone concrete is selected as the material for laying the protective layer 3. The construction workers first lay the welded steel mesh, and then pour the concrete. Before pouring, the embedded blocks 101 are buried inside the protective layer 3. The embedded parts 10 include embedded blocks 101 and screws 102. The upper surface of the embedded block 101 is fixedly connected to the screw 102, and the screw 102 passes through the protective layer 3.

[0033] After the protective layer 3 is completed, wait for the concrete of the protective layer 3 to reach the specified strength before constructing the insulation layer 4. The construction personnel first install the installation grid 8. The installation grid 8 includes several horizontal bars 801 and vertical bars 802 that are overlapped vertically and horizontally. Each horizontal bar 801 includes multiple horizontal bar 801 unit sections that can be spliced ​​with each other. During the installation process, the screws 102 are all located inside the corresponding avoidance openings 11, and the upper ends of the screws 102 simultaneously pass through the avoidance openings 11 on the horizontal bars 801 or the vertical bars 802. The grid of the installation grid 8 is filled with insulation boards 9, and the insulation boards 9 are initially bonded to the protective layer 3 through adhesives.

[0034] Then the construction workers insert the locking piece into the avoidance opening 11. The locking piece includes a connecting tube 103 and a locking plate 104. The upper surface of the connecting tube 103 is fixedly connected to the locking plate 104. The interior of the connecting tube 103 is provided with a threaded hole with a lower opening. The threaded hole is provided with a threaded connection adapted to the screw 102. The construction workers rotate the locking piece so that the connecting tube 103 is threadedly connected to the outer surface of the corresponding screw 102. At the same time, the outer surface of the connecting tube 103 contacts the inner wall of the avoidance opening 11, so that the horizontal bar 801 and the vertical bar 802 are fixed more firmly.

[0035] The upper surface of the locking plate 104 is fixedly connected with a bolt head 105 . Construction workers use tools such as wrenches to rotate the bolt head 105 , thereby driving the locking plate 104 to rotate, which saves manpower.

[0036] At the same time, the locking plate 104 is a cross-shaped structure, and the width of the locking plate 104 is greater than the width of the horizontal bar 801 and the vertical bar 802. The locking plate 104 rotates downward as the connecting tube 103 rotates until the lower surface of the locking plate 104 contacts the outer surface of the insulation plate 9. The locking piece cooperates with the screw 102 and presses the insulation plate 9 onto the insulation layer 4 through the edge of the locking piece, so that the insulation plate 9 is assisted in fixing.

[0037] Then, an adhesive layer 5 is laid on the insulation layer 4. The adhesive layer 5 is made of mortar. The adhesive layer 5 covers the locking part so that the locking part is located inside the adhesive layer 5. Then, roofing tiles are laid on the adhesive layer 5 to form a roofing layer 6.

[0038] Therefore, when the insulation layer 4 is laid, the installation grid 8 can be quickly installed through the embedded parts 10, and then the insulation board 9 can be filled into the grid of the installation grid 8, and then the installation grid 8 can be reinforced by the locking parts. At the same time, the locking parts can press the insulation board 9 on the insulation layer 4, so that the insulation board 9 is not easy to fall off in windy weather. At the same time, after the insulation board 9 is damaged, the construction workers will lift the roof tiles, and then rotate the embedded parts 10 to replace the insulation board 9 at the corresponding position, so as to facilitate the maintenance of the insulation layer 4.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is determined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
