Description

Technical Field

[0001] The utility model specifically relates to a roof waterproof structure, belonging to the technical field of roof waterproofing. Background Art

[0002] Roof waterproofing refers to the waterproof treatment of the building roof to prevent rainwater, snowmelt or other liquids from seeping into the building interior, thereby protecting the building structure and preventing leakage and water-related diseases; in the prior art, roof waterproofing usually includes a flat plate, a waterproof layer and a protective layer. The flat plate is arranged on the top of the building for leveling the plane, the protective layer is arranged on the top of the flat plate and used to protect the flat plate, and the waterproof layer is arranged on the top of the protective layer and used to waterproof the flat plate. The existing roof waterproof structure, such as the Chinese patent authorization publication number: 222009398U, discloses a roof waterproof structure, including a waterproof layer, the insulation layer is installed at the bottom of the waterproof layer, the support layer is installed at the bottom of the insulation layer, and the protective layer is installed at the top of the waterproof layer. By setting the waterproof layer and the support layer, when it rains, rainwater accumulates on the product, and the gravity of the rainwater will be supported by the support layer. Since the insulation layer has a certain elasticity, when the waterproof layer is arranged on the top surface of the insulation layer, moisture penetration is likely to occur in the gaps between the insulation layers. Summary of the Utility Model

[0003] To solve the above problems, the utility model proposes a roof waterproof structure, which sets up a two-layer waterproof structure on the roof and establishes a thermal insulation system on the roof through a thermal insulation support unit; and can avoid damage to the waterproof structure.

[0010] During construction, first clean and polish the roof to form a treatment surface. Then, roll on an asphalt waterproof coating on the treatment surface. The application of the asphalt waterproof coating is divided into two times, and the coating thickness is 2 - 4 mm. Next, after waiting for the asphalt waterproof coating to cure, apply an adhesive on the bottom surface of the thermal insulation support unit. Then, press the thermal insulation support unit onto the top surface of the asphalt waterproof coating, and make the thermal insulation rock wool sheets between adjacent thermal insulation support units squeeze each other. At the same time, form V-shaped grooves that communicate with each other on the top surfaces of adjacent thermal insulation support units. Then, fill and inject glue into the V-shaped grooves, and scrape the filled material to cure and obtain a waterproof cross-linking strip. Finally, sequentially bond and cover the top surface of the thermal insulation support unit with an HDPE self-adhesive waterproof coiled material.

[0011] Further, the roof includes a roofing surface, and a sprayed rapid-set rubber asphalt layer with a thickness of 1.5 mm, a concrete slope-forming layer, and a concrete leveling layer are sequentially arranged from bottom to top on the bottom surface of the roofing surface.

[0013] Further, an outer edge is integrally formed on the top surface of the HDPE protection sheet. The slope surfaces of adjacent HDPE protection sheets form V-shaped grooves, and limiting edges are formed on both sides of the top surface of the V-shaped groove through the outer edge. When the waterproof filler is filled into the V-shaped groove, an elastic waterproof system can be formed, and the outer edge can limit the waterproof cross-linking strip.

[0014] Further, the waterproof filler is a one-component asphalt-based polyurethane waterproof coating.

[0015] Further, a pipe penetrates through the roof. A first cylinder base and a second cylinder base are sleeved outside the pipe. The bottom surface of the first cylinder base is bonded to the top surface of the HDPE self-adhesive waterproof coiled material; waterproof filler is filled between the first cylinder base and the pipe. The second cylinder base is fitted outside the first cylinder base, and the bottom surface of the second cylinder base is bonded to the first cylinder base; when a pipe such as a water pipe or a ventilation pipe needs to penetrate through the roof, first sleeve the first cylinder base and the second cylinder base outside the pipe, and fill waterproof filler between the first cylinder base and the pipe, which can prevent moisture from entering the building interior through the gap between the pipe and the roof; the second cylinder base can cover and protect the first cylinder base; the first cylinder base is bonded to the top surface of the HDPE self-adhesive waterproof coiled material, and the second cylinder base is bonded to the first cylinder base, so as to bond and obtain the entire waterproof structure.

[0016] Further, a fiberglass mesh is laid on the top surface of the HDPE self-adhesive waterproof coiled material, and a layer of fine stone concrete with a thickness of 30 - 50 mm is poured outside the fiberglass mesh. Through the layer of 30 - 50 mm of fine stone concrete, the HDPE self-adhesive waterproof coiled material can be protected, and the fiberglass mesh can support and protect the fine stone concrete.

[0017] Compared with the prior art, for the roof waterproof structure of the present utility model, an asphalt waterproof coating is sprayed on the top surface of the roof, enabling the top surface of the roof to always have a waterproof effect. The thermal insulation support unit is composed of an HDPE protection sheet with structural strength and a thermal insulation rock wool sheet in cooperation, endowing the top surface of the roof with a thermal insulation effect. The adjacent thermal insulation rock wool sheets in the thermal insulation support unit are pressed against each other to form an integral body, and the HDPE protection sheet has stress dispersion, capable of reducing the deformation amplitude of the thermal insulation rock wool sheet. A waterproof cross-linking strip is arranged between the HDPE protection sheets, enabling the top surface of the HDPE protection sheets to form a whole; it can prevent rainwater from penetrating into the inner side of the thermal insulation support unit, and a second waterproof layer can be formed on the top surface of the thermal insulation support unit through the HDPE self-adhesive waterproof coiled material, and it can provide structural support for the thermal insulation support unit.
