Description

Technical Field

[0001] This utility model belongs to the field of construction, and in particular relates to an integrated prefabricated exterior wall panel and its installation structure. Background Technology

[0002] my country's housing construction has shifted from large-scale new construction to urban renewal and renovation. In the past few decades, due to various factors such as design concepts, material performance, and construction techniques, the overall quality of housing has many defects, especially in the exterior walls, which have suffered from numerous problems such as cracking, peeling, deformation, fire hazards, and leaks. Some exterior walls have even completely collapsed, seriously affecting public safety and property. Traditionally, exterior walls have mostly used cast-in-place concrete or reinforced concrete structures as the main load-bearing units. Various functions of the exterior walls are completed on-site step-by-step by different professionals. The drawbacks of this approach are complex procedures, numerous junctions, long construction periods, mutual constraints and waiting times between different processes, numerous potential quality hazards, and unclear responsibilities. Currently, some new materials and processes are being used in the renovation of old buildings, but the vast majority still follow the on-site construction model. Construction efficiency and quality heavily depend on the enthusiasm and skill level of the on-site manual laborers.

[0003] To address this, an integrated prefabricated exterior wall panel has been invented, combining insulation, decoration, waterproofing, and fireproofing functions. Suitable for new buildings, especially for the renovation of old houses, this panel is ideal. The entire panel is manufactured in the factory and then quickly installed on-site. Once installed, the exterior wall possesses excellent decorative, insulation, waterproofing, and fireproofing functions. Some panels can also integrate wall greening and photovoltaic power generation. The application of this technology and product can significantly improve the performance of building exterior walls, enhance construction quality, simplify on-site construction procedures, reduce on-site installation labor, lower construction costs, and reduce construction dust, noise, and waste, thus creating substantial economic and social benefits. Summary of the Invention

[0004] The purpose of this utility model is to provide an integrated prefabricated exterior wall panel and its installation structure, aiming to solve the problems existing in the background art. To achieve this purpose, the technical solution adopted by this utility model is:

[0005] An integrated prefabricated exterior wall panel and its installation structure include: a decorative surface layer, an insulation layer, wall panel embedded parts, special connectors, and structural embedded parts. The decorative surface layer is made of ultra-high performance concrete and is located on the outer side of the exterior wall panel, with basalt or fiberglass mesh as the load-bearing mesh inside. The insulation layer is made of autoclaved aerated concrete and is located on the inner side of the decorative surface layer. The wall panel embedded parts are pre-embedded inside the exterior wall panel and are mainly used to anchor the right hook in the special connectors. The special connectors are used to connect the prefabricated exterior wall panel to the main structure. The structural embedded parts are pre-embedded inside the main structure and are mainly used to anchor the left hook in the special connectors. The prefabricated exterior wall panel is a flat panel with tongue and groove joints at both ends. Its overall length is 600–3000 mm, width is 200–2000 mm, and thickness is 50–300 mm. The dimensions in the three directions vary in 10 mm increments. It can be customized according to the client's and design requirements and can also be made into curved panels or corner panels.

[0006] Preferably, the compressive strength of the decorative surface layer is not less than 100MPa and the flexural strength is not less than 15MPa. Specific performance indicators can be determined by the client and the designer. The thickness is determined according to the panel size and stress calculation, and is considered to be 10 to 50mm. The decorative surface layer can also be made into various shapes, textures, qualities and colors according to the client and the design requirements.

[0007] Preferably, the insulation layer is made of autoclaved aerated concrete with a compressive strength of not less than 6MPa and a density of not more than 800kg / m³. The thickness is determined by thermal and stress calculations. Reinforcing bars can also be added inside the insulation layer. The reinforcing bars are made of galvanized or rust-proof painted steel wire mesh. The reinforcing bars in the insulation layer are connected to the reinforcing mesh in the decorative surface layer by stainless steel hooks. The number and spacing of the reinforcing bars are determined by stress calculations. Truss mesh can also be used to form the connection.

[0008] Preferably, the wall panel embedded parts are made of metal, and are galvanized long nut embedded parts with anchor plates, buried to a depth of 20mm from the outer surface. The size is determined by design calculation. The area around the embedded parts is made of ultra-high performance concrete that is integrally cast with the decorative surface layer within a range of 50-100mm.

[0009] Preferably, the special connector consists of bolts, a left hook, a right hook, a washer, and mortar. The bolts are used to connect the left and right hooks, the washer is used to adjust the flatness of the structure and the outer surface of the hanging plate, and the mortar is used to protect the hook joint and fill and fix the gap between the left and right hooks to prevent the hooks from shifting and being damaged due to wind load factors.

[0010] Preferably, the structural embedded parts are welded parts on the steel structure, including embedded parts in cast-in-place concrete, embedded parts in precast concrete, and post-installed expansion bolts, the size and quantity of which are determined by the design.

[0011] Preferably, the wall panel can also be pre-embedded with windows, balcony doors, openings, pipelines or other pre-embedded parts.

[0012] The beneficial effects of this utility model are:

[0013] With a high degree of integration, the wall integrates insulation, decoration, waterproofing and fireproofing functions, greatly reducing the number of on-site work procedures and time in the later stage.

[0014] The installation is highly efficient. The exterior wall panels are all prefabricated, and the joints are dry-connected, which allows for quick installation and effectively improves installation efficiency.

[0015] The quality is reliable because all production processes of the exterior wall cladding are prefabricated in the factory, reducing on-site operations and ensuring safer and more reliable quality.

[0016] Cost reduction: Because the exterior wall cladding reduces on-site work processes and time, it effectively reduces labor costs, resulting in a significant reduction in overall costs. Attached Figure Description
