Environmentally friendly and energy-saving connector for composite exterior wall panels and method of using the same

Abstract

The present invention relates to the technical field of building prefabricated components, in particular to an environment-friendly and energy-saving connector for composite exterior wall panels, which includes a straight pipe, and the two ends of the straight pipe are respectively fixed with a first brace and a second brace. The struts are set close to the inner leaf wall, the second struts are set close to the outer leaf wall, the straight pipe passes through the insulation layer, and the straightened carbon fiber rope is passed through the straight pipe, and the first and second struts are equipped with The inner diameter of the circular hole for the carbon fiber rope to pass through matches the diameter of the carbon fiber rope. One end of the carbon fiber rope is pre-embedded in the inner leaf wall, and the other end is embedded in the outer leaf wall. In view of the deficiencies in the prior art, the purpose of the present invention is to provide an environmentally friendly and energy-saving connector for composite exterior wall panels and its use method, which can overcome the damage to the outer leaf concrete caused by repeated freezing and expansion of the connector, and improve the strength of the connector. Advantages of durability. The invention has the advantages of overcoming the damage to the concrete of the outer leaves caused by repeated freezing and swelling of the connecting parts and improving the durability of the connecting parts.

Description

technical field [0001] The invention relates to the technical field of building prefabricated components, in particular to an environment-friendly and energy-saving connector for composite exterior wall panels and a method for using the same. Background technique [0002] The following defects generally exist in the connectors for composite exterior wall panels of existing steel structure buildings and reinforced concrete buildings: [0003] 1. The existing composite exterior wall panels on the market currently use metal connectors between the inner and outer leaf reinforced concrete and sandwich energy-saving materials. Although they meet the requirements for tie strength and durability, due to the "cold bridge" of the connectors As a side effect, condensed water is generated in the winter in the north, followed by freezing and swelling, and repeated freezing and swelling lead to damage to the outer leaf concrete, which seriously affects the service life of the building; ...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing composite exterior wall panels on the market currently use metal connectors between the inner and outer leaf reinforced concrete and sandwich energy-saving materials. Although they meet the requirements for tie strength and durability, due to the "cold bridge" of the connectors As a side effect, condensed water is generated in the winter in the north, followed by freezing and swelling, and repeated freezing and swelling lead to damage to the outer leaf concrete, which seriously affects the service life of the building;

[0004] 2. The FRP connectors used for composite exterior wall panels are made of glass fiber reinforced plastics made of certain resins, which have poor aging resistance and durability, and have a greater impact on the durability of buildings.
