Description

An assembled multifunctional integrated external wall panel

Technical Field

The utility model belongs to the technical field of assembled steel frame structures, and in particular relates to an assembled multifunctional integrated external wall panel.

Background Art

Prefabricated steel frame structures have the characteristics of large use space, high assembly efficiency, recyclability, short construction period, fast investment recovery, and low environmental pollution. They are in line with the national construction industrialization policy and have developed rapidly in recent years, becoming the key development direction of my country's construction industry. The enclosure system selected for steel structure buildings must not only meet the requirements of the safety, beauty and practicality of the external enclosure system structure, the coordinated deformation of the exterior wall panels and the main structure, but also realize the integration of multiple performances such as thermal insulation, sound insulation, waterproofing, and decoration. At present, there are many types of wall panels used in steel structures in the field of prefabricated buildings, but the main ones are still strip panels and integrated wall panels. Compared with integrated wall panels, strip panels have the disadvantages of small panels, many joints, and poor durability. At this stage, the integrated external wall panels generally use concrete external wall panels, which have the disadvantages of heavy weight, complex construction and installation, and high cost. Some other types of new wall panels are usually difficult to realize the integration of multiple functions such as structural earthquake resistance, thermal insulation, and decoration, and need to be installed through on-site construction. The insulation layer and decorative layer are more complicated during construction, and the amount of high-altitude operations is large, making it difficult to achieve the purpose of rapid installation.

Summary of the invention

The technical problem to be solved by the utility model is to provide an integrated external wall panel that is easy to install, light and energy-saving. It is a lightweight wall panel that integrates enclosure, decoration, waterproofing, heat insulation and other properties. The wall panel is composed of a light steel keel frame, rock wool, ceramic decorative panels and calcium silicate boards. The light steel keel frame is composed of a main keel and a secondary keel welded or bolted together, which serves as the main load-bearing component and provides rigidity for the integrated external wall panel. The wall panel is connected to the main structure of the steel frame and between the wall panels by setting a connection node on the keel frame. The wall panel is filled with rock wool insulation and fireproof materials with a fireproof grade of A1. Rock wool has the advantages of stable performance, thermal insulation, strong hydrophobicity, green environmental protection and effective flame spread. The outer side of the wall panel adopts a ceramic decorative panel as a decorative component, which is connected to the keel frame through a corresponding ceramic panel connector. The ceramic decorative panel is used as a facade covering material, which has the advantages of low water absorption, easy renovation, and convenient dry hanging installation. It is suitable for assembly construction and can improve the aesthetic effect of the exterior wall. The sides and back of the wall panels are encapsulated with calcium silicate boards, and finally the joints are waterproofed with waterproof sealant. The above structure can overcome the shortcomings of the existing technology for prefabricated steel structure buildings, and provide a multifunctional integrated prefabricated external wall panel with dual assembly properties of factory assembly and on-site assembly. The construction efficiency and construction speed are significantly improved. The wall panel size can be freely controlled, and the wall panel has good load-bearing, rigidity and crack resistance. At the same time, it has many excellent properties such as light weight and energy saving, low environmental pollution, etc., which can meet the needs of building energy conservation and architectural decoration integration. It is more suitable for prefabricated steel structure buildings. The wall panel structure uses green and environmentally friendly materials, which helps the country's dual carbon strategy and has significant social, economic and environmental benefits.

The calcium silicate board is connected to the inner side and the surrounding sides of the wallboard on the light steel keel frame by self-tapping screws, and serves as the decorative material on the indoor side of the integrated external wallboard;

In order to ensure that the wall panels have good sealing properties and increase the service life of the multifunctional integrated external wall panels, sealants are used for joint treatment inside the wall panel frame, between the calcium silicate board joints and the ceramic decorative panels.

Furthermore, the light steel keel frame is formed by the main keel and the secondary keel intersecting vertically and horizontally, the main keel is used around the frame and in the longitudinal direction, and the secondary keel is used in the transverse direction. The vertical main keel unit is a complete main keel, and the two ends of the secondary keel are welded or bolted to the main keel; the transverse main keel unit is also a complete main keel, and the two ends of the vertical main keel unit are welded to the transverse main keel. The above keels are made of cold-bent square steel pipes; the welding areas are all rust-proofed.

The spacing of the secondary purlins is determined according to the size of the ceramic decorative panels. Due to the different sizes of the primary and secondary purlins, the installation surface of the ceramic decorative panels should be flush when welding the light steel keel frame to facilitate the installation of the ceramic decorative panels.

Rock wool is used as thermal insulation material in the above-mentioned light steel keel frame. The fire resistance grade of rock wool is A1. It has the advantages of stable performance, thermal insulation, good hydrophobicity, green environmental protection and effective flame spread isolation.

The thickness of the calcium silicate board is 10mm. The calcium silicate board is installed in a longitudinal arrangement. The long side of the board falls on the vertical main keel. When docking, it should be naturally close and must not be put into place by strong pressure. When fixing the calcium silicate board, the board and the keel should be drilled. The hole diameter should be 1mm smaller than the diameter of the self-tapping screw to ensure the stability of the connection. When fixing with self-tapping screws, it should be fixed from the middle of the board to the periphery, and all screw heads should be sunk into the board surface. When tightening, the board must be nailed to the keel frame, thereby realizing the decoration and edge sealing of the multifunctional integrated external wall panel.

The sealant used is a neutral silicone sealant, which has strong bonding force and high tensile strength. It is also weather-resistant, vibration-resistant, moisture-proof, odor-resistant, and adaptable to large changes in temperature. It can ensure the durability of the multifunctional integrated external wall panels and prevent the internal light steel keel frame from corroding and affecting the safe service of the overall wall panels.

In the above structure, the assembled multifunctional integrated external wall panels are prefabricated in the factory. The specific preparation process is to weld the main keel and the secondary keel to form a keel frame, drill the keel, fix the calcium silicate board on the side and back of the keel frame with self-tapping screws, and fill the light steel keel frame with rock wool, so that the wall panel and the insulation board are integrated when leaving the factory.

The construction sequence is usually from the outer surface to the inner surface, from the inside of the wall panel to the outside of the wall panel.

Preferably, the width of a single panel of the assembled multifunctional integrated external wall panel should be controlled within 6.6 m, and should be split if it is too wide.

In summary, the light steel keel frame in this application is welded and combined by the main keel and the secondary keel, which serves as the main load-bearing member and provides rigidity for the integrated external wall panel. The connection between the wall panel and the main structure of the steel frame and between the wall panels is realized by setting connection nodes on the keel frame. The interior of the wall panel is filled with rock wool insulation and fireproof materials with a fireproof grade of A1. Rock wool has the advantages of stable performance, thermal insulation, strong hydrophobicity, green environmental protection and effective isolation of flame spread; the outer side of the wall panel adopts ceramic decorative panels as decorative components, which are connected to the keel frame through corresponding ceramic panel connectors. The ceramic decorative panels are used as facade covering materials, which have the advantages of low water absorption, easy renovation, and convenient dry hanging installation.
