[0032] In this embodiment, the base box is a box body with a bottom but no cover. The base box 1 is in a rectangular parallelepiped shape and has an upper box opening.

[0033] In some embodiments, the box wall of the base box is hollowed out to facilitate the flow of concrete and improve the bonding strength between the base box and the concrete.

[0034] There are two groups of support assemblies 2. Each group of support assemblies 2 includes a socket sleeve 21 and two support rods 22.

[0035] One end of the two support rods 22 is movably inserted into the two ends of the socket sleeve 21. In this embodiment, the socket sleeve is a rectangular sleeve. The cross section of the support rod is rectangular. The outer diameter of the support rod is smaller than the inner diameter of the socket sleeve.

[0036] The other ends of the two support rods 22 are formed with clamping plates 23. The socket sleeve is arranged in the horizontal direction. The two ends of the support rod extend downward to form clamping plates. The clamping plates 23 of the two support rods 22 are pressed against the opposite sides of the upper box opening respectively. An elastic member 24 is installed in the socket sleeve 21. The elastic member 24 is used to tie the support rod 22.

[0037] The upper and lower sides of the socket sleeve 21 are respectively formed with sliding grooves. The support rod 22 is provided with a plurality of through holes.

[0038] The length of the telescopic assembly 3 is adjustable. The telescopic assembly 3 is connected between the socket sleeves 21 of the two support assemblies 2.

[0039] The embedded rod 4 is used to install the steel structure. The embedded rod 4 is inserted into a through hole on the support rod 22. The middle part of the embedded rod is slidably arranged in the upper and lower slide grooves of the socket sleeve. The upper end of the embedded rod extends above the socket sleeve for installing the steel structure. The bottom of the base box 1 is supported on the lower end of the embedded rod 4. The embedded rod 4 is installed with a locking member 41. The locking member 41 is used to lock the socket sleeve 21.

The pipe openings of the socket sleeve 21 are respectively provided with inserting openings. An inserting plate 25 is detachably inserted in the inserting opening. The inserting plate 25 is formed with two baffles 26 movably arranged between the support rod 22 and the inner wall of the socket sleeve 21. The elastic member 24 is supported between the baffle 26 and the ear plate 221.

[0041] As a preferred implementation, the elastic member 24 is a spring.

[0042] In this embodiment, an anti-skid pad layer is laid on the inner side of the clamping plate 23. The anti-skid pad layer is a rubber layer.

[0043] Continue reading Figure 3 As shown, the upper part of the embedded rod 4 is formed with an external thread. The locking piece 41 is formed with a threaded hole.
