Description

Technical Field

[0001] The utility model belongs to the technical field of roof waterproofing, and in particular relates to a roof waterproofing structure with cement tile strips for new concrete surfaces in old residential areas. Background Art

[0002] There are many cast-in-place concrete surfaces on the roofs of old residential areas. Most of the large flat surfaces are not waterproofed. Waterproofing membranes are usually laid at the eaves and gutters. The waterproofing quality of the large surface mainly depends on the hanging of large tiles. Water flows to the gutters through the tiles, and the roof water is guided through the gutters. However, as time goes by, the tiles gradually age, and the large concrete surfaces are prone to leakage. There is also a risk of the waterproofing membrane sliding off the inclined roof. In order to solve the waterproofing problem of old residential areas, the utility model designs a new waterproofing structure for cement tile strips on new concrete surfaces in old residential areas. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a waterproof structure for a cement tile-hanging roof on a new concrete surface in old residential areas, which effectively solves the problem of roof leakage in old residential areas.

[0004] The utility model achieves the above technical objectives through the following technical means.

[0005] A waterproof structure for a cement tile strip roof used for new concrete surfaces in old communities, comprising a cement mortar repair layer and an anti-cracking mortar leveling layer sequentially constructed on the floor concrete in a damaged roof area, a cement tile strip being arranged on the anti-cracking mortar leveling layer, a waterproof membrane being adhered to the cement tile strip and the surface of the anti-cracking mortar leveling layer by means of a non-curing rubber asphalt waterproof coating and being compacted; an L-shaped aluminum alloy strip being fixed on the roof, a top of the L-shaped aluminum alloy strip being higher than the cement tile strip and a side thereof being closely fitted with a right-angled side of the cement tile strip, and a corrugated tile being hung on the L-shaped aluminum alloy strip.

[0006] Furthermore, installation holes are provided on the L-shaped aluminum alloy strip and the corresponding installation roof, and the holes are coated with non-curing rubber asphalt waterproof coating and covered with waterproof coiled material.

[0007] Furthermore, the coating thickness of the non-curing rubber asphalt waterproof coating is 2 mm.

[0008] Furthermore, the waterproof membrane is a 1.5 mm thick polymer self-adhesive waterproof membrane.

[0009] Furthermore, the L-shaped aluminum alloy strip is fixed to the roof through expansion bolts, and the bottom of the expansion bolts extends into the floor concrete.

[0010] The utility model has the following beneficial effects:

[0011] The utility model is a waterproof structure constructed on the original large concrete roof when renovating old residential areas. It is a new type of waterproof structure, which solves the problems of roof leakage and waterproofing in old residential areas. Moreover, due to the design of a metal pressure edge strip with a top slightly higher than the cement tile hanging strip, tiles can still be hung stably after waterproofing on the cement tile hanging strip, which solves the risk of slipping of the waterproof membrane on the sloping roof and the problem that tiles cannot be hung after the tip of the tile hanging strip becomes rounded after being covered with the membrane. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The utility model is a schematic diagram of the waterproof structure of the cement tile roof.

[0013] In the figure: 1-corrugated tile; 2-non-curing rubber asphalt waterproof coating; 3-waterproof membrane; 4-tile hanging opening; 5-expansion bolt; 6-anti-cracking mortar leveling layer; 7-floor concrete; 8-cement mortar repair layer; 9-L-shaped aluminum alloy strip; 10-cement tile hanging strip. DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0015] like Figure 1 As shown, the utility model is used for the waterproof structure of cement tile strips on new concrete surfaces in old communities, including corrugated tiles 1, non-curing rubber asphalt waterproof coating 2, waterproof membrane 3, expansion bolts 5, L-shaped aluminum alloy strips 9, cement tile strips 10, anti-cracking mortar leveling layer 6, and cement mortar repair layer 8.

[0016] The non-curing rubber asphalt waterproof coating 2 is applied with a thickness of 2 mm, and the waterproof membrane 3 is a 1.5 mm thick polymer self-adhesive waterproof membrane.

[0017] like Figure 1 As shown, for the damaged area of ​​the roof, a cement mortar repair layer 8 and an anti-cracking mortar leveling layer 6 are sequentially constructed on the floor concrete 7, and a cement tile strip 10 is newly constructed on the anti-cracking mortar leveling layer 6; the surface of the cement tile strip 10 and the surface of the anti-cracking mortar leveling layer 6 are coated with a 2 mm thick non-curing rubber asphalt waterproof coating 2, and the waterproof membrane 3 is adhered to the surface of the cement tile strip 10 and the anti-cracking mortar leveling layer 6 through the non-curing rubber asphalt waterproof coating 2 and compacted to ensure that there are no bubbles or hollows.
