Description

Technical Field

[0001] The invention relates to an external wall panel connection system, a wall panel node structure and an installation method, and belongs to the technical field of assembled buildings. Background Art

[0002] At present, my country is vigorously developing prefabricated buildings. Prefabricated external wall panels are important enclosure structures of prefabricated buildings. The heavy weight, lack of insulation and design innovation of connection nodes of prefabricated components are the key points and difficulties in the design, production and construction of prefabricated buildings, and are also the links most prone to quality problems after the completion of the construction project.

[0003] At present, large-scale prefabricated exterior wall panels for prefabricated buildings have begun to be used in large quantities. Various composite exterior wall panels integrate the performance of enclosure, fire prevention, heat preservation, heat insulation, sound insulation, anti-corrosion, anti-seepage and other external protective wall to varying degrees. However, there has been no concise and effective solution to the installation, connection, positioning, fixing and adaptation of the main structure to the stress and deformation of the exterior wall panel enclosure system, and no simple and easy connection methods and assembly measures have been found. It is urgent to solve the problems of complex and difficult connection of exterior wall panels, high cost and several quality risks.

[0004] 1. Comprehensive requirements for connection performance: The connection between the external wall panels and the building structure must meet the requirements of durable earthquake resistance, coordinated deformation, precise stability, and internal force resolution to meet structural safety requirements. It must also be fireproof and anti-corrosive to meet physical performance requirements. It must not form too many cold bridges to meet energy-saving performance requirements.

[0005] 2. Error control of installation conditions: There are multiple levels of errors in the installation conditions of exterior wall panels, including structural errors, component errors, embedded parts errors, and connector errors. These errors are all at the centimeter level, but the wall panel installation error must be controlled at the millimeter level. Error adjustment is one of the core issues of exterior wall panel installation.

[0006] 3. Weight control of unitized wall panels: For external wall panels, it is advisable to use unitized whole-room large panels, but the weight of the unitized wall panels should be reasonably designed to make the connecting parts small and simple. For unitized external wall panels weighing more than 4 tons, try not to use them or take weight reduction and thinning measures.

[0007] 4. The installation operation is simple and accurate: The installation and construction of external wall panels involves complex and comprehensive factors such as structure, humidity, deformation, connection, error, energy saving, fire prevention, corrosion prevention, and anti-seepage. How to comprehensively deal with these factors and achieve a strong, durable, safe, and efficient wall panel connection through a new type of connection method and connectors is the key to ensuring excellent external wall panel performance.
