Description

TECHNICAL FIELD

[0001] The utility model belongs to the construction protection field, especially a adjustable clamp connecting structure of wall temporary protective fence. BACKGROUND

[0002] In the field of building construction, it is inevitable to set up temporary protective measures at various construction hole positions to solve the production safety problems existing in the construction site. The protective fence commonly used at present is a finished structure, which needs to destroy the structure on both sides of the protective fence, such as opening bolt holes on both sides of the wall, and then installing the finished protective fence through expansion bolts and fasteners. In order to solve this problem, the prior art such as announcement number CN220889580U discloses an adjustable edge hole protective device, which is a protective fence welded by steel pipes and a plurality of connecting pieces. The sleeve of the connecting piece is sleeved on the horizontal rail to adjust the width of the hole. The hook-shaped member of the connecting piece passes through the bolt sleeve connected perpendicularly to the sleeve, and the tightness of the hook-shaped member clamped on the back side of the wall is adjusted. This technology still has the following problems:

[0003] 1. Since the protective fence is designed as a protective fence frame composed of a group of horizontal rails and two vertical rails, the connecting piece is designed to need to be set on the horizontal rails of the protective fence in multiple pairs to stabilize the protective fence.

[0004] 2. The connecting piece is set at different heights and needs to be operated at multiple points for installation and disassembly, which is still very cumbersome to assemble and disassemble.

[0005] 3. The connecting position of the connecting piece is limited to the horizontal rail of the protective fence. If there is an error in the manufacture of the protective fence and the connecting piece, the installation error of the connecting piece on both sides of the protective fence after installation will inevitably occur, which will cause the installation form of the overall connecting piece on the wall to be very messy, affecting the cleanliness of the construction site.

[0006] 4. The hook-shaped member is clamped on the back side of the wall, although the head of the member is provided with a rubber head, but the point load of the hook-shaped member on the wall will still damage the back surface of the wall.

[0007] 5. The connecting piece only has the hook-shaped member and the nut, and after the sleeve sleeve and the bolt sleeve are installed on the horizontal rail, they become an integral part of the protective fence and cannot be removed. The connecting piece and the protective fence need to be designed and used integrally, and the recyclability is not strong. CONTENT OF THE UTILITY MODEL
