Description

Technical Field

[0001] The utility model belongs to the technical field of building roofs and relates to a roof structure of a light steel structure house. Background Art

[0002] With the overall development requirements of my country's cities, various commercial service industries such as light industrial plants, sports stadiums, entertainment venues, public buildings, warehouses and storage and transportation facilities, exhibition halls and supermarkets and retailers have also increased year by year. Correspondingly, there are more and more buildings with various roofing systems. The roofs of such buildings usually use light steel roofs. However, due to design and construction reasons, leakage at the eaves of light steel roofs is common and the quality of wall waterproofing projects is poor.

[0003] In response to the above problems, people have made various improvements, and some have even applied for patents. For example, Chinese patent literature discloses a light steel roof waterproof structure [patent number: 202021610724.5; application publication number: CN213268620U], which includes longitudinal beams, transverse beams, plywood, supporting mechanisms and waterproof mechanisms; the waterproof mechanism includes corrugated plates, asphalt shingles, insulation layers, gutters and plywood. The bottom surface of the plywood is fixedly connected to the top surface of the longitudinal beam, the bottom side of the plywood is covered on the top surface of the asphalt shingle layer, the bottom surface of the asphalt shingle layer is covered on the top surface of the insulation layer, and the bottom surface of the insulation layer is covered on the top surface of the corrugated plate. The top surface of the corrugated plate is fixed to the top surface of the top rod by bolts, and the side base of the gutter is fixedly connected to the side wall of the transverse beam by bolts.

[0004] This type of waterproof structure uses a laminated panel to prevent rainwater from seeping between the fixed corrugated panels, asphalt shingles, and insulation layer. However, in actual use, some rainwater will inevitably seep between the fixed corrugated panels, asphalt shingles, and insulation layer. This leakage can cause the insulation layer to swell and deform, rendering the roof ineffective in both waterproofing and insulation, leading to damage to the roof. Summary of the Invention

[0005] The purpose of this utility model is to solve the above problems existing in the prior art and propose a roof structure of a light steel structure house. The technical problem to be solved is how to improve the waterproof effect of the roof structure and ensure the thermal insulation effect of the roof structure.

[0006] The purpose of the utility model can be achieved through the following technical solutions: A roof structure of a light steel structure house, comprising asphalt tiles, a supporting top formed by assembling steel pipes and arranged obliquely, and a fixed plate fixedly connected to the supporting top, characterized in that the roof structure also includes a fine stone concrete layer, an EPS concrete slope layer and a concave-convex drainage board, the drainage board is fixedly connected between the fixed plate and the EPS concrete slope layer, a flow space for water to pass through is provided between the drainage board and the fixed plate, the fine stone concrete layer is fixedly connected to the top of the EPS concrete slope layer, and the asphalt tiles are fixedly connected to the top of the fine stone concrete layer.

[0007] The drainage board is concave and convex, with a flow space between the drainage board and the fixed plate for water to flow through. Even if some rainwater leaks into the roof structure, it will be discharged through this flow space. Furthermore, the flow space generates a flowing wind, keeping the roof structure dry and improving its waterproofing. At the same time, since the flow space is filled with air, the air has a low thermal conductivity, forming a thermal bridge that effectively blocks heat conduction, increases thermal insulation, and ensures the thermal insulation of the roof structure. The EPS concrete graded layer is relatively light, which can reduce pressure on the roof of the house. At the same time, the EPS concrete graded layer has good thermal insulation and low water absorption. It can work in conjunction with other waterproof structures to effectively improve the overall performance of the roof system, prevent the impact of water penetration on the roof's thermal insulation performance, improve the waterproofing of the roof structure, and ensure the thermal insulation of the roof structure.

[0008] In the aforementioned roof structure of a light steel structure house, the drainage board includes a board body and a plurality of protruding columns protruding from the bottom of the board body. There is a certain distance between two adjacent protruding columns. The protruding columns have a receiving groove inside. The receiving groove passes through the top of the drainage board. The bottom end of the protruding column is fixedly connected to the fixed plate. The EPS concrete slope layer is partially embedded in the receiving groove to securely connect the drainage board to the EPS concrete slope layer. The protruding columns and the receiving groove form a concave-convex structure in the drainage board. The space between all the protruding columns cooperates with the fixed plate to form a flow space. The provision of the receiving groove allows the drainage board and the EPS concrete slope layer to be tightly combined. This structure of the drainage board ensures the overall strength of the roof structure, improves the waterproof effect of the roof structure, and ensures the thermal insulation effect of the roof structure.

[0009] In the above-mentioned roof structure of a light steel structure house, the bottom end of the boss is fixed to the fixing plate by point bonding with asphalt grease, or the bottom end of the boss is fixed to the fixing plate by hot melt welding, or the bottom end of the boss is embedded and fixed in the fixing plate.

[0010] In the aforementioned light steel structure house roof structure, the distance between two adjacent protrusions is between 50-60 mm, and the height of the drainage plate is between 25-30 mm. This structure ensures that the flow space has sufficient flow area, thereby improving drainage and heat insulation effects.

[0011] In the above-mentioned roof structure of a light steel structure house, the drainage board is made of HDPE material, wood-plastic material, or hard plastic material.

[0012] In the above-mentioned roof structure of a light steel structure house, the asphalt shingles are fiberglass-based asphalt shingles.

[0013] In the above-mentioned roof structure of a light steel structure house, the fixing plate is an OSB plate with a thickness of 13-18 mm.

[0014] In the above-mentioned roof structure of a light steel structure house, the density of the fine stone concrete layer is 2000-2200 kg / m 3 The thickness of the fine stone concrete layer is between 30-50 mm, and the fine stone concrete layer is made of cement, silica fume, micro beads, ultrafine cementitious materials and medium sand.

[0015] In the roof structure of the light steel structure house, the fine stone concrete layer and the EPS concrete slope leveling layer are roughened to improve the connection strength between the fine stone concrete layer and the EPS concrete slope leveling layer.

[0016] In the above-mentioned roof structure of a light steel structure house, the asphalt shingles, the fixing plates, the drainage plates, the fine stone concrete layer and the EPS concrete slope leveling layer are all arranged at an inclination.

[0017] Compared with the prior art, the roof structure of a light steel structure house provided by the utility model has the following advantages:

[0018] 1. The drainage board of this roof structure is concave and convex. There is a flow space between the drainage board and the fixed plate for water to pass through. Even if some rainwater leaks into the roof structure, the leaked rainwater will be discharged through the flow space. In addition, flowing wind will be generated in the flow space, which will keep the roof structure dry and improve the waterproof effect of the roof structure. At the same time, since the flow space is filled with air and the air thermal conductivity is low, a thermal bridge is formed, which effectively prevents heat conduction, increases the thermal insulation effect, and ensures the thermal insulation effect of the roof structure.

[0019] 2. The EPS concrete slope layer of this roof structure is relatively light in weight, which can reduce the pressure on the roof of the house. At the same time, the EPS concrete slope layer has good thermal insulation and low water absorption. The EPS concrete slope layer can work together with other waterproof structures to effectively improve the overall performance of the roof system, avoid the impact of water penetration on the thermal insulation performance of the roof, improve the waterproof effect of the roof structure, and ensure the thermal insulation effect of the roof structure.
