Description

Technical Field

[0001] This invention relates to the field of building decoration and renovation technology, and more specifically, to a method for preventing slippage of insulation boards on pitched roofs. Background Technology

[0002] Currently, the main anti-slip measure for roof insulation boards is to pre-install Φ10 steel rebar ends on the roof, spaced 800×800mm, with a rebar end length generally 100-150mm. The rigid protective layer of the roof is typically reinforced with Φ4@100×100 steel mesh. The pre-installed rebar ends and the steel mesh form a unified structure to achieve the anti-slip effect. However, roof construction involves numerous steps, and the pre-installed rebar ends increase the difficulty of each step, while also posing a risk of water leakage. Furthermore, workers on pitched roofs are prone to tripping or being scratched by the pre-installed rebar ends, posing a significant safety hazard. Summary of the Invention

[0003] To address the problems existing in the prior art, the purpose of this invention is to provide a construction method for preventing slippage of insulation boards on pitched roofs. The insulation boards have a significant anti-slip effect, while reducing leakage and safety hazards.

[0004] The present invention adopts the following technical solution:

[0005] A method for preventing slippage of insulation boards on pitched roofs includes the following steps:

[0006] During the construction of the roof structure, a reinforced concrete flange is added at the eaves, with the flange height higher than the finished surface of the insulation board.

[0007] After the roof structure is completed, the leveling layer and waterproofing layer of the roof are installed.

[0008] When laying the roof insulation boards, the dry laying method is changed to spot bonding, staggered laying, and then bonding. After the insulation boards are laid, a non-woven fabric isolation layer is laid.

[0009] Multiple steel meshes are overlapped on both sides of the roof insulation board, and steel mesh 2 is placed at the top ridge of the roof insulation board. Steel mesh 1 is fully tied with wire between steel mesh 1 and between steel mesh 1 and steel mesh 2. Steel mesh 1 is integrated with the concrete on both sides of the roof to form a whole.

[0010] Furthermore, the waterproof layer is a waterproof membrane, which covers the leveling layer and the flange.

[0011] Furthermore, the height and width of the flange are 100-150mm.

[0012] Furthermore, when laying the roof insulation boards, polymer adhesive mortar should be used for connection, and the bonding area should not be less than 60%.

[0013] Furthermore, the reinforcing mesh 1 overlaps with each other, and the reinforcing mesh 1 overlaps with the reinforcing mesh 2.

[0014] Furthermore, the overlap length between steel mesh 1 and steel mesh 2 is 100mm.

[0015] Furthermore, the second steel mesh is cold-bent from the middle of the first steel mesh to form the ridge angle.

[0016] Beneficial effects

[0017] Compared with the pre-embedded rebar anti-slip construction method, this invention makes the construction of each process on the roof more convenient, and greatly reduces water leakage and safety hazards; the flanged edge at the eaves effectively solves the problem of insulation board slippage without affecting the overall appearance of the roof. The anti-slip effect of the insulation board in this invention is more significant, and the construction difficulty is greatly reduced. Attached Figure Description

[0018] Figure 1 This is a schematic diagram after construction according to an embodiment of the present invention. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] As shown in the figure, this invention discloses a method for preventing slippage of insulation boards on pitched roofs, comprising the following steps:

[0021] During the construction of roof structure 1, a reinforced concrete flange 5 is added at the eaves. The height of flange 5 is higher than the finished surface of insulation board 3. Flange 5 should not be too high to ensure unobstructed drainage and prevent rainwater from accumulating at flange 5. The flange reinforcement is tied together with the reinforcement of roof structure 1 to ensure integrity. The roof structure here can be a roof panel.

[0022] The folded edge prevents the insulation board from sliding down and also makes it easier for operators to work on the sloping roof.

[0023] After the roof structure 1 is completed, the leveling layer 7 and waterproof layer 4 of the roof are constructed.

[0024] When laying the roof insulation board 3, the dry laying method is changed to spot bonding, staggered laying, and then bonding. After the insulation board 3 is laid, a non-woven fabric isolation layer is laid; the insulation board 3 is laid on the waterproof layer 4.

[0025] Multiple steel meshes 1-2 are overlapped on both sides of the roof insulation board 3. Steel mesh 2-1 is placed at the top ridge of the roof insulation board 3. Steel meshes 1-2 and steel mesh 2-1 are fully tied with wire. Steel meshes 1-2 are connected to the concrete on both sides of the roof to form a whole, which also plays a certain role in preventing slippage.

[0026] In one embodiment of the present invention, the waterproof layer 4 is a waterproof membrane, which covers the leveling layer and the flange.

[0027] In one embodiment of the present invention, the height and width of the flange 5 are 100-150mm.

[0028] In one embodiment of the present invention, when the roof insulation board 3 is laid, polymer bonding mortar is used for connection, and the bonding area is not less than 60%.

[0029] In one embodiment of the present invention, the steel mesh 12 overlaps with the steel mesh 2, and the steel mesh 12 overlaps with the steel mesh 21.

[0030] After the steel mesh 1-2 is tied together and the steel mesh 1-2 is tied together with the steel mesh 2-1, the protective layer is poured in time. The pitched roof is generally a tiled roof. After the rigid protective layer is poured, the tile laying is carried out last.

[0031] In one embodiment of the present invention, the overlap length between steel mesh 1-2 is 100mm, and the overlap length between steel mesh 1-2 and steel mesh 2-1 is 100mm. All overlaps are fully secured to prevent displacement during concrete pouring.

[0032] In one embodiment of the present invention, the steel mesh 21 is cold-bent from the middle of the steel mesh 2 to form a ridge angle.

[0033] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
