Description

Technical Field

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

[0002] Currently, my country's housing construction has entered a new stage. On the one hand, the requirements for the thermal insulation performance, exterior decoration, and fire resistance of new buildings are becoming increasingly stringent, and many existing technologies are defective and unsuitable. On the other hand, many buildings constructed in the past few decades have poor exterior wall insulation performance, insufficient thermal insulation and fire resistance, insufficient durability of exterior wall cladding, and are prone to peeling. There are also a large number of exterior wall cracks, hollow areas, and leaks, which seriously threaten people's lives and property safety and waste a lot of energy and resources.

[0003] To address these issues, an exterior wall composite panel and corresponding construction process have been invented. By using steel wire mesh and UHPC as the panel substrate, it solves the problems of insufficient strength and fragility (compared to stone and ceramic tiles) of past exterior wall decorative layers. The use of prefabricated standardized slotted back panels solves problems such as weak connections between the decorative layer and the main structure, non-standard construction operations, and insufficient panel rigidity leading to deformation. The use of colored, textured UHPC as the surface decoration solves the problems of insufficient durability, poor decorative effect, and poor environmental adaptability of existing decorative materials. The use of fixed connecting long slots on the structural wall solves the problems of structural safety, eliminates installation hazards, and reduces installation difficulty. The post-filling of insulation material between the main structure and the composite panel solves problems related to exterior wall insulation, waterproofing, insect prevention, connectors, and corrosion protection. The application of this invention will greatly improve the performance and quality of building exterior walls, creating significant economic and social benefits. Summary of the Invention

[0004] The purpose of this utility model is to provide a slotted exterior wall composite 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] A slotted exterior wall composite panel and its installation structure include: a composite panel body, a back-ribbed clip, a pre-installed slot, a post-filled insulation layer, and a joint waterproof strip. The composite panel body is prefabricated using ultra-high performance concrete and has a decorative layer. The back-ribbed clip is embedded in the back of the composite panel body. The pre-installed slot is used to connect the back-ribbed clip. The post-filled insulation layer is between the composite panel body and the main structure. The joint waterproof strip is located around the perimeter of the composite panel body.

[0006] Preferably, the composite panel body is made of precast ultra-high performance concrete with a compressive strength of not less than 150MPa, a tensile strength of not less than 15MPa, and a thickness of 20-30mm. It is internally equipped with galvanized steel wire mesh and has a decorative layer on the outer surface. Its color, texture and pattern are customized according to the designer's intention. The thickness is 0-30mm. It is made of ultra-high performance concrete (UHPC) with a compressive strength of not less than 100MPa and a tensile strength of not less than 10MPa.

[0007] Preferably, the back-ribbed clips are embedded on the back of the composite panel body and are made of stainless steel. After passing the stress calculation and durability test, they can also be made of galvanized steel, aluminum alloy or other composite materials. The specific dimensions are determined by structural calculations. Modular standard parts are used and connected to the wire mesh in the composite panel by anchor bolts. They are then cast into a whole in the factory using UHPC.

[0008] Preferably, the pre-installed slot is used to connect the back-ribbed clip and the main structure of the building. It is a combination of a flat plate and a "C"-shaped slot. The front of the "C"-shaped slot is connected to the back-ribbed clip, and the back of the "C"-shaped slot is welded to the flat plate. Both the "C"-shaped slot and the flat plate are provided with bolt holes. The "C"-shaped slot corresponds to the back-ribbed clip, forming a mortise and tenon structure during later installation. The material is galvanized steel or stainless steel. The pre-installed slot is fixed in the main structure using mechanical anchors or chemical anchors. The specific method is determined by the design. When the main structure is a steel structure, welding bolts or through bolts can also be used.

[0009] Preferably, the post-fill insulation layer is located between the composite panel body and the main structure. The material is polyurethane, expanded perlite cement mortar, or foamed concrete. The specific material is determined based on thermal performance calculations. The filling method is to inject the insulation material into the space between the composite panel and the main structure under pressure through a special pipe. The material fills all the space by its own weight or volume expansion, thus wrapping the back edge type clips, pre-installed slots, and other connectors.

[0010] Preferably, the joint waterproof strip is located around the perimeter of the composite board body and is made of elastic weather-resistant rubber. Its main function is to seal the insulation material to prevent it from overflowing from the joints, as well as to provide waterproofing, insulation and insect prevention for the wall surface in the later stage.

[0011] The beneficial effects of this utility model are:

[0012] (1) Using steel wire mesh and UHPC as the substrate of the panel: This method solves the problem of insufficient strength and easy breakage of the exterior wall decoration layer in the past, and improves the durability and safety of the exterior wall.

[0013] (2) Adopting a slotted back panel design: This design solves the problems of weak connection between the decorative layer and the main structure, non-standard construction operation, and insufficient rigidity of the board that makes it easy to deform, thus improving the standardization and efficiency of construction.

[0014] (3) Use colored, often decorated UHPC as surface decoration: This method solves the problems of insufficient durability, poor decorative effect and poor environmental adaptability of existing decorative materials, and improves the aesthetics and environmental performance of buildings.

[0015] (4) Fixing long grooves on structural walls: This method solves the problems of external wall stress safety, eliminates installation hazards, reduces installation difficulty, and enhances building safety.

[0016] (5) Fill the space between the main structure and the composite panel with insulation material: This method solves the problems of external wall insulation, waterproofing, insect prevention, connectors and structural external wall corrosion prevention, and improves the building's energy efficiency and living comfort.
