AI Technical Summary
During construction, the existing load-bearing connectors are prone to longitudinal anchor rods falling off due to their own weight, resulting in unstable connections and affecting the overall stability and load-bearing capacity of the sandwich insulation wall.
A load-bearing connector for sandwich insulation walls designed to prevent slippage is achieved by setting a rotatable baffle and a retaining ring on the anchor rod and cooperating with the groove to realize the interlocking structure of the longitudinal and transverse anchor rods, ensuring that the anchor rods do not slip under gravity or vibration.
It effectively prevents anchor rods from slipping, improves the anti-detachment capability of connectors, ensures effective transmission of in-plane shear force, and enhances the overall stability and stress coordination of sandwich wall structures.

Abstract
Claims
1. A fall-preventing type of load bearing connecting member for a sandwich thermal insulation wall, characterized in that, include: H-beam (1) is used to provide an installation reference for the outer blades; A pair of first anchor rods (2) are inserted through the flange of the H-beam (1), a first gap is formed between the two first anchor rods (2), a second gap is formed between the two first anchor rods (2) and the web of the H-beam (1), and the side wall of the first anchor rod (2) has a groove (21). Several second anchor rods (3) are rotatably inserted through the web of the H-beam (1), all located between the first gaps of the two first anchor rods (2). The sidewall of the second anchor rod (3) has a baffle (31) located in the second gap and a retaining ring (32) that cooperates with the groove (21). When the second anchor rod (3) is inserted, the rotating drive baffle (31) rotates from the direction along the first anchor rod (2) to form an angle with it, and the retaining ring (32) engages with the groove (21) to constrain the position of the first anchor rod (2) and the second anchor rod (3).
2. The anti-falling type sandwich thermal insulation wall force connecting piece according to claim 1, characterized in that: The length of the baffle (31) on each of the second anchor rods (3) is longer than the gap between adjacent second anchor rods (3).
3. The anti-falling type sandwich thermal insulation wall force connecting piece according to claim 2, characterized in that: Each of the second anchor rods (3) has two baffles (31) on its sidewall, and the two baffles (31) are collinear.
4. The anti-falling type sandwich thermal insulation wall load bearing connecting piece according to claim 3, characterized in that: The minimum distance between the two sides of the retaining ring (32) is the same as the size of the first gap between the paired first anchor rods (2).
5. The anti-falling type sandwich thermal insulation wall load bearing connecting piece according to claim 4, characterized in that: The second anchor rod (3) has a stop (33) on its side wall between the baffle (31) and the retaining ring (32) to restrict the position of the second anchor rod (3). When the retaining ring (32) engages with the groove (21), the stop (33) is attached to the bottom of the first anchor rod (2).
