Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to a tile roof structure for preventing rainwater from flowing back. Background Art
[0002] Tile roof is a traditional roof form, mainly covered with tiles to achieve the purpose of waterproofing and protecting the internal structure of the building. It has a long history in China and is an important part of traditional Chinese architecture.
[0003] However, in rainy cities, especially on windy days or typhoon days, the bad weather will not only bring heavy rain, but the strong wind will also cause rainwater to seep back into the house through the gaps in the tiles, which can easily cause serious leakage and then affect the structure of the house. Summary of the Invention
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a tile roof structure that prevents rainwater from flowing back.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a tile roof structure for preventing rainwater from backflowing, which includes, from the inside to the outside, a first structural plate, a mortar leveling layer, a second structural plate, an insulation layer, a waterproof layer, a drainage layer, a tile surface and a ridge, the drainage layer being evenly provided with a plurality of drainage grooves, and a grid support plate being arranged above the drainage grooves; the drainage grooves are inwardly concave triangular grooves; the drainage grooves are arranged below the arched tile surface.
[0006] Preferably, a polymer waterproof coiled material is laid on the bottom of the drainage layer, the drainage trough is cast with concrete, and a smooth alloy plate is laid in the trough.
[0007] Preferably, the gaps between the grid support plates are adapted to the length of the tiles.
[0008] Preferably, the insulation layer is paved with expanded perlite insulation board.
[0009] Preferably, fine stone concrete is laid between the waterproof layer and the drainage layer.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] The utility model adds a triangular drainage groove under the tile so that when rainwater flows back through the gaps between the tiles, it can quickly slide down the drainage groove, preventing rainwater from accumulating in the tiles and reducing the risk of infiltration; further, the drainage layer is waterproofed and a smooth alloy plate is laid in the groove to reduce the friction of rainwater, causing it to drip faster, preventing rainwater from accumulating and avoiding leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic diagram of the drainage layer structure of the first embodiment of the present utility model.
[0014] Explanation of reference numbers: 100—first structural board; 200—mortar leveling layer; 300—second structural board; 400—insulation layer; 500—waterproof layer; 600—drainage layer; 700—tile surface; 800—ridge; 601—grid support plate; 602—drainage trough. DETAILED DESCRIPTION
[0015] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application, as follows.
[0016] Please refer to Figure 1 as well as Figure 2 The utility model provides a tile roof structure for preventing rainwater from flowing back. From the inside to the outside, it includes a first structural plate 100, a mortar leveling layer 200, a second structural plate 300, an insulation layer 400, a waterproof layer 500, a drainage layer 600, a tile surface 700 and a ridge 800. The drainage layer 600 is evenly provided with a plurality of drainage grooves 602, and a grid support plate 601 is arranged above the drainage grooves 602; the drainage grooves 602 are inwardly concave triangular grooves; the drainage grooves 602 are arranged below the arched tile surface 700.
[0017] Preferably, the bottom of the drainage layer 600 is paved with a polymer waterproof membrane, and the drainage trough 602 is cast using concrete, with a smooth alloy plate laid inside the trough. Further waterproofing of the drainage layer 600 and laying a smooth alloy plate inside the trough reduce friction with rainwater, causing it to drip more quickly, preventing accumulation of rainwater and preventing leakage.
[0018] Preferably, the gaps between the grid support plates 601 are adapted to the length of the tiles.
[0019] Preferably, the insulation layer 400 is paved with expanded perlite insulation board, which has good thermal insulation performance, is easy to transport and construct, and is easy to cut.
[0020] Preferably, fine stone concrete is laid between the waterproof layer 500 and the drainage layer 600 to protect the waterproof layer 500 from external damage.
[0021] When rainwater is blown into the gaps between tiles by the wind, it flows along the tiles, flows onto the roof under the action of gravity, and then slides into the drainage groove 602. Since the drainage groove 602 is triangular and is paved with smooth alloy plates, it speeds up the collection of rainwater while reducing the friction of rainwater, making it drip faster, preventing the accumulation of rainwater and avoiding leakage.
[0022] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
