Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically to an anti-slip structure between layers of a pitched roof and its construction method. Background Technology

[0002] The construction of pitched roofs involves multiple stages, including the roof concrete structure, waterproofing layer, insulation layer, isolation layer, and protective layer. Due to the large slope of the roof, the construction process is prone to quality problems such as insufficient control of the coordinated deformation of multiple materials, delamination between material layers, roof cracking and leakage, and low wind pressure resistance. This makes the later maintenance of pitched roofs quite difficult.

[0003] Patent application CN109707114A discloses a construction method for anti-slip treatment of tiled roofs, including the following steps: S1, construction of anti-slip water-stop reinforcement: including the fabrication and pre-embedding of anti-slip water-stop reinforcement; S2, construction of anti-slip treatment of the roof base layer: including the construction of the roof bonding layer and the roof insulation layer; S3, construction of the waterproof layer; S4, construction of anti-slip treatment of roof tiles: including the binding of steel mesh, the binding of Z-shaped steel bars, and the construction of the roof tiles. This solution mainly focuses on the anti-slip treatment of roof tiles. However, the overall anti-slip deformation performance between the multiple layers involved in the roof still needs to be emphasized and improved. Summary of the Invention

[0004] Due to the aforementioned deficiencies in existing technologies, this invention provides an anti-slip structure for interlayer pitched roofs and its construction method, which can effectively solve the problems of difficult construction control of anti-slip force in concrete pitched roof structural layers, waterproof layers, insulation layers and protective layers, and easy cracking of roof protective layers, thus ensuring the construction quality of pitched roofs.

[0005] To achieve the above objectives, in a first aspect, the present invention provides an anti-slip structure for interlayer roofing of a building, comprising, from top to bottom, a fine stone concrete protective layer, an isolation layer, an insulation board layer, a waterproof membrane layer, a waterproof coating layer, and a roof reinforced concrete structure layer.

[0006] The roof reinforced concrete structure layer is pre-embedded with pre-embedded steel bars perpendicular to the pitched roof, and the pre-embedded steel bars extend out of the insulation board layer;

[0007] The insulation board layer has grooves cut into it, with the grooves parallel to the ridge direction. Each groove has an injection hole spaced apart. Structural adhesive is injected through the injection holes to bond and fix the insulation board layer to the waterproof membrane layer underneath.

[0008] The fine aggregate concrete protective layer is equipped with a steel mesh; the steel mesh is fixedly connected to the pre-embedded steel bars.

[0009] The above technical solution involves pre-embedding steel bars in the concrete roof structure layer. Through the coordination of the pre-embedded steel bars with the arrangement of each layer of the roof, the protective layer, isolation layer, insulation board layer, waterproof membrane layer, and the reinforced concrete roof structure layer are subjected to overall stress. Grooves are made on the insulation board and glue is injected to form an insulation layer that is firmly bonded to the base layer. This effectively improves the overall anti-slip deformation capacity of the concrete pitched roof structure layer, waterproof layer, insulation layer, and protective layer.

[0010] Furthermore, the embedded reinforcing bars are hot-dip galvanized steel bars with a longitudinal and transverse spacing of 800~1200mm. Extending beyond the insulation board layer in the longitudinal direction, their ends are fixedly connected to the reinforcing mesh of the fine aggregate concrete protective layer. The corrosion resistance and reasonable spacing of the embedded reinforcing bars enhance the overall effect of the integrated roof layers.

[0011] Furthermore, the waterproof coating layer is a 1.5mm thick polymer cement waterproof coating; the waterproof membrane layer is two 1.5mm thick self-adhesive polymer modified bitumen waterproof membranes.

[0012] Furthermore, the spacing of the grooves on the insulation board layer is 800~1200mm to ensure that the insulation board layer effectively adheres to the waterproof layer.

[0013] Furthermore, the isolation layer is a PE (polyethylene) isolation film.

[0014] Furthermore, the fine aggregate concrete protective layer is a C20 fine aggregate concrete protective layer reinforced with Φ6@200 bidirectional steel bars.

[0015] Secondly, the present invention provides a construction method for an anti-slip structure between floors of a pitched roof, comprising the following steps:

[0016] S1. Construction of the reinforced concrete structural layer of the roof: pre-embedded steel bars perpendicular to the pitched roof in the reinforced concrete structural layer of the roof, with the length of the steel bars extending out of the insulation board.

[0017] S2. After the concrete pouring of the sloping roof is completed, the base layer is treated, and waterproof coating is applied in sequence, followed by laying two coats of self-adhesive polymer modified bitumen waterproof membrane.

[0018] S3. Grooves are cut into the insulation board, with the grooving direction parallel to the ridge direction, and injection holes are left at intervals in each groove.

[0019] S4. Lay the insulation board in the direction of the groove, parallel to the ridge; fix the insulation board by penetrating and fixing it with the pre-embedded steel bars, inject structural adhesive into the injection hole, and bond it to the bottom waterproof layer.

[0020] S5. Lay the isolation layer;

[0021] S6. Tie the protective layer steel mesh, fix the steel mesh to the pre-embedded steel bars, and pour the fine stone concrete protective layer.

[0022] Furthermore, in step S2, the pre-embedded steel bars are reinforced with waterproof coating to prevent leakage.

[0023] The above technical solution is only one feasible technical solution of the present invention. The scope of protection of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0024] The above invention has the following advantages or beneficial effects:

[0025] This method solves the problem of interlayer slippage and cracking in the structural layer, waterproof layer, insulation layer and protective layer of pitched roofs, ensuring the construction quality of pitched roofs and making construction convenient. Attached Figure Description

The standard parts and materials used are all commercially available, and can be customized according to the description and drawings.

[0031] See Figure 1This invention provides an anti-slip structure for interlayer roofing of a building, comprising, from top to bottom: a C20 fine stone concrete protective layer 11 (with Φ6@200 bidirectional steel bars), a PE film isolation layer 12, a B1 grade XPS (extruded polystyrene) insulation board layer 13, a 1.5mm thick self-adhesive polymer modified bitumen waterproof membrane layer 14, a 1.5mm thick polymer cement waterproof coating layer, and a reinforced concrete roofing structure layer 15.

[0032] The construction process of the above sliding structure is as follows:

[0033] ① Construction of the roof reinforced concrete structural layer 15: Φ10 hot-dip galvanized steel bars are pre-embedded in the roof reinforced concrete structural layer 15. The steel bar ends are welded to the steel bars of the roof reinforced concrete structural layer 15 and the direction is kept perpendicular to the pitched roof panel. The length of the steel bars is reserved to extend 30mm beyond the XPS insulation board. The longitudinal and transverse spacing of the pre-embedded hot-dip galvanized steel bars is 1000mm.

[0034] ② After the concrete pouring of the pitched roof is completed, the base layer is treated by sequentially applying a 1.5mm thick polymer cement waterproof coating and laying two 1.5mm thick self-adhesive polymer modified bitumen waterproof membranes. The hot-dip galvanized steel bar ends are reinforced with waterproof coating to prevent leakage.

[0035] ③ Cut grooves 22 on the XPS insulation board. The direction of grooves 22 is parallel to the direction of the roof ridge. The groove width is 40mm, the groove depth is 30mm, and the groove spacing is 1000mm. Leave a 20mm injection hole every 1m in each groove.

[0036] ④ Lay the XPS insulation board layer 13 in the same direction as the groove 22, parallel to the roof ridge. The insulation board layer 13 is fixed by penetrating and fixing it with the end of a Φ10 hot-dip galvanized steel bar. High-performance structural adhesive is injected into the injection hole and bonded to the bottom waterproof membrane layer 14.

[0037] ⑤ Lay out the PE release film layer.

[0038] ⑥ Tie the reinforcing mesh 23 of the protective layer, spot weld the reinforcing mesh 23 to the pre-embedded Φ10 hot-dip galvanized steel bars, and pour the C20 fine stone concrete protective layer 11.

[0039] As described above, the anti-slip structure provided by this invention, through the coordination of pre-embedded steel bars with the arrangement of each layer of the roof, enables the protective layer, isolation layer, insulation board layer, waterproof membrane layer and the reinforced concrete structure layer of the roof to be stressed as a whole. Grooves are made on the insulation board and glue is injected to form an insulation layer that is firmly bonded to the base layer, effectively improving the overall anti-slip deformation capacity among the concrete pitched roof structure layer, waterproof layer, insulation layer and protective layer.
