Detachable foundation cage

Abstract

A detachable foundation cage mainly comprises a lower bracket, a lower pull rod, an upper bracket and an upper pull rod, wherein the lower bracket and the upper bracket are U shapes with upward openings; the two ends of the lower pull rod are fixed to two parallel lower bracket rods of the lower bracket respectively; a downwardly sunk lower pull rod groove is formed in the center of the top wall of the lower pull rod; the lower bracket and the upper bracket are vertically intersected; an upper bracket groove enters a lower bracket groove, so that after combination of the upper bracket and thelower bracket, the bottom is stable; an upper pull rod groove enters a lower pull rod groove; correspondingly, all upper pull rod bevels and all lower pull rod bevels enter an included angle formed after intersection of the upper pull rod and the lower pull rod respectively; the two side walls of each upper pull rod bevel and each lower pull rod bevel are pressed against the upper pull rod and thelower pull rod respectively, so that the upper bracket and the lower bracket are not affected by a lateral force and keep stable; locking screws screwed on the upper pull rod are pressed against lower pull plates on the lower pull rod from bottom to top, so that the upper bracket does not break away from the lower bracket upwardly; during transportation and storage, the detachable foundation cageis small in volume.

Description

technical field [0001] The invention belongs to a street lamp foundation cage, in particular to a detachable foundation cage. Background technique [0002] Upright columns such as street light poles, utility poles or steel structure columns are usually fixed on the ground by foundation cages for use. Existing foundation cages are usually welded together with several steel bars to form an integrated steel structure. When in use, use external force to press into the cement mortar for positioning, or put the foundation cage into a pre-dug hole before watering The cement mortar is positioned, and finally the lampposts, utility poles, etc. are fixed on the top of the foundation cage. The foundation cage of the integrated steel structure has a large volume, and the storage and transportation costs are relatively high. [0003] In the patent document No. 2018202283225, a storeable street lamp ground cage is disclosed, which includes a first embedded bracket and a second embedded ...

Problems solved by technology

The disadvantage is that the sockets of the first reinforcing rod and the second reinforcing rod are easy to disengage up and down. Although there are fasteners for fastening, the materials of the fasteners are different, and the fasteners need to be knocked during assembly, which is troublesome to assemble. There is a machining error between the first reinforcing rod and the second reinforcing rod, resulting in the first embedded bracket and the second embedded bracket still swinging left and right and difficult to fix
