DETAILED DESCRIPTION

The present invention will be further described below in conjunction with specific embodiments and drawings.

Referring to Figures 1 and 2, an anti-leakage construction structure for a rainwater pipe node of an exterior wall thermal insulation and decoration integrated panel is mainly used for thermal insulation of building exterior walls.

A mortar leveling layer 2 is provided on the outside of the exterior wall 1, and the thickness of the mortar leveling layer 2 is 15 to 25 mm (preferably 20 mm thick) to overcome the original slope and unevenness of the exterior wall 1 and facilitate the construction of the insulation layer. An adhesive layer 3 is provided on the outside of the mortar leveling layer 2, and an insulation decoration integrated board 4 is provided on the outside of the adhesive layer 3. The adhesive layer 3 is used to achieve bonding and fixing of the insulation decoration integrated board 4.

The thermal insulation decorative integrated board 4 on the outside of the exterior wall 1 is a composite board that integrates thermal insulation and decorative functions. The thermal insulation decorative integrated board 4 includes a high-strength inorganic resin face plate 41, a vertical rock wool thermal insulation core plate 42 and a high-strength inorganic resin bottom plate 43, and the boards of the thermal insulation decorative integrated board 4 are bonded by adhesive. A paint finishing layer is pre-coated on the face plate for decoration. The face plate and the bottom plate serve as internal and external protective surfaces to protect and support the internal thermal insulation core plate, and the thermal insulation core plate performs thermal insulation.

The inner end of the expansion bolt assembly 5 is fixed in the outer wall 1, the middle part of the expansion bolt assembly 5 is inserted into the inter-plate gap of the thermal insulation decorative integrated board 4, and the outer end of the expansion bolt assembly 5 is connected to the clamp 6. The expansion bolt assembly 5 is used to fix the clamp 6 on the outer wall 1, and the clamp 6 is used to support the rainwater pipe 7. In addition, the expansion bolt assembly 5 is located in the gap between the panels instead of opening a hole in the thermal insulation decorative integrated board, which ensures the integrity of the thermal insulation layer and improves the construction quality and thermal insulation effect.

The expansion bolt assembly 5 includes a sleeve 51, an extension screw 52, a nut 53 and a protective sleeve 54. The sleeve 51 is fixed in the outer wall 1, the inner end of the extension screw 52 is fixed in the sleeve 51, the middle part of the extension screw 52 is threadedly connected with a nut 53, the middle part of the extension screw 52 is located in the gap between the plates, and the outer end of the extension screw 52 is connected to the clamp 6. During installation, the sleeve 51 and the extension screw 52 are placed in the hole of the outer wall 1 in advance, and then the nut 53 is rotated and tightened, and the sleeve 51 expands to realize the anchoring of the extension screw 52 in the outer wall 1.

The protective cover 54 is sleeved on the middle part of the extension screw 52 in the gap between the plates. The protective cover 54 is preferably made of PVC material to protect the extension screw 52 and improve the durability of the extension screw 52. The clamp 6 is also made of PVC material. The end of the clamp 6 is provided with a threaded seat, and the extension screw 52 is connected to the thread of the clamp 6.

A rainwater pipe 7 is arranged on the outer side of the heat preservation and decoration integrated board 4, and the rainwater pipe 7 is used for drainage. The rainwater pipe 7 is fixed on the hoop 6 to achieve stable installation of the rainwater pipe 7.

A sealing component 8 is provided between the thermal insulation decorative integrated board 4 and the expansion bolt assembly 5. The sealing component 8 is located at the opening of the gap between the boards. The sealing component 8 waterproofs the gap between the two to prevent rainwater leakage from affecting the internal expansion bolt assembly. The sealing component 8 includes an outer sealant 81 and an inner foam strip 82, forming two waterproof layers to enhance the waterproof effect.

The working process of the utility model is as follows: deepening of the thermal insulation decorative integrated board → fixing of the rainwater pipe expansion bolts → installation of the specially made extended screw rod → installation of the thermal insulation decorative board → installation of the rainwater pipe → sealing and gluing of the bracket.

In order to ensure that the rainwater pipe bracket (hoop) can be installed at the grid of the exterior wall insulation decoration integrated panel, it is necessary to comprehensively consider the position of the rainwater pipe and the standard spacing of the bracket setting, and deepen the layout of the exterior wall insulation decoration integrated panel in advance.

The rainwater pipe bracket is connected to the main structure with an expansion bolt assembly, and the rainwater pipe clamp is connected to the expansion bolt through a special extended screw rod, so as to fix the rainwater pipe bracket. The rainwater pipe bracket, expansion bolt and special extended screw rod need to be confirmed and installed in advance according to the detailed drawing. After the overall construction of the exterior wall insulation decoration integrated board is completed, the exterior wall rainwater pipe can be installed. After the above processes are inspected and qualified, the foam strips and sealants at the nodes can be installed.

To ensure durability, the rainwater pipe’s specially made extended screw rod is protected by a PVC casing on the outside. The rainwater clamp is made of PVC with wire on the end, and its connection with the specially made extended screw rod is threaded.
