An environmentally friendly and energy-saving connector for composite exterior wall panels and its production method

Abstract

The invention relates to the technical field of building prefabricated components, in particular to an environment-friendly and energy-saving connecting piece for a composite outer wallboard and a production method thereof. The connecting piece comprises a connecting rod, wherein an anchoring piece used for anchoring in an inner blade wall is arranged at one end of the connecting rod, and a clamping piece used for clamping steel bars in an outer blade wall is arranged at the other end of the connecting rod; the connecting rod comprises a metal core rod; the metal core rod is wrapped with an anti-aging rubber soft sleeve; the clamping piece is connected with the metal core rod; and the anchoring piece comprises a movable body which is made of metal and at least three claw blocks which are also made of metal, and all the claw blocks surround the movable body and the metal core rod and are uniformly distributed at intervals. The connecting piece and the production method have the advantages of avoiding the damage to outer leaf concrete caused by repeated frost heaving of the connecting piece and improving the durability of the connecting piece; and by increasing the contact area of the connecting piece and heat insulation layers, the heavier heat insulation layers are prevented from being crushed by the connecting piece, the heat insulation effect is indirectly improved, the purposes of energy conservation and emission reduction are achieved, meanwhile, environmental resources are indirectly protected, and the environment-friendly effect is achieved.

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 production method thereof. Background technique [0002] Existing steel structure buildings and reinforced concrete building composite exterior wall panels generally have the following defects: [0003] 1. The existing composite exterior wall panels on the market currently use metal connectors between the inner and outer leaf reinforced concrete and the sandwich energy-saving materials. Although they meet the requirements of tie strength and durability, due to the "cold bridge" of the connectors The side effect is that condensation water is produced in the northern winter, and the subsequent freeze-swell occurs. Repeated freeze-swell causes damage to the outer leaf concrete, which seriously affects the service life of the building; [0004] 2. The FRP connectors...

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.
