[0031] Reference is made to the drawings Figs. 1-3 The utility model provides a kind of steel structure column foot fixing device of quick installation and dismantling, it includes: side support frame 1, top support rod 2, telescopic device 3 and wedge plug 4, top support rod 2 is transversely arranged, and its two ends are connected with side support frame 1 and telescopic device 3 respectively, the end of telescopic device 3 away from top support rod 2 is connected with wedge plug 4, and the distance between wedge plug 4 and top support rod 2 can be adjusted by telescopic device 3.

[0032] When using the device, side support frame 1 is arranged on the base outside cup mouth 5, the other end of top support rod 2 is extended above cup mouth 5, telescopic device 3 and wedge plug 4 are arranged at the part of top support rod 2 above cup mouth 5, then steel structure column 6 is lifted into cup mouth 5 using lifting equipment, the length of telescopic device 3 is adjusted to extend so that wedge plug 4 falls into cup mouth 5 and a pair of opposite side surfaces respectively abut against the side wall of cup mouth 5 and the side wall of steel structure column 6, by arranging the column foot fixing device around steel structure column 6, temporary and circumferential abutment and limiting of steel structure column 6 can be realized to prevent it from being inclined, after steel beam is installed and cup mouth 5 is poured with concrete, the length of telescopic device 3 is adjusted to shorten so that wedge plug 4 is raised to completely separate from cup mouth 5, since wedge plug 4 abuts against steel structure column 6, welding and welding removal processes in traditional technology are not involved, not only the base material of steel structure column 6 can be prevented from being damaged, but also installation and dismantling are convenient, and construction efficiency is high.

[0033] The auxiliary connecting rod 7 is transversely arranged and perpendicular to the top supporting rod 2, and both ends of the auxiliary connecting rod 7 are respectively provided with detachable connecting blocks 8, and the connecting blocks 8 are respectively connected with different stretchers 3. By adding the auxiliary connecting rod 7 and the connecting block 8, the number of stretchers 3 connected with the wedge-shaped plug 4 is increased, and the efficiency and stability of the height adjustment of the wedge-shaped plug 4 are improved through the synchronous action of multiple groups of stretchers 3.

[0034] In order to facilitate the turnover of the device, the connecting block 8 is sleeved on the auxiliary connecting rod 7 in the embodiment, so that it can slide along the axial direction of the auxiliary connecting rod 7 or be fixed by the locking member one 9. When the locking member one 9 is detached, the connecting block 8 can be completely separated from the auxiliary connecting rod 7, so that the problem of occupying too much space and being difficult to turn over under the condition of complete connection of the device is avoided, and the distance between adjacent stretchers 3 can be changed by sliding the connecting block 8, so that multiple groups of stretchers 3 are evenly distributed on the top of the wedge-shaped plug 4, and the counterweight is balanced.

[0035] Referring to the accompanying drawings, Fig. 2 The side support frame 1 of the embodiment includes a bottom plate 1.1 and a vertical plate 1.2, the bottom plate 1.1 is fixed to the bottom of the vertical plate 1.2, and the vertical plate 1.2 is sleeved on the top supporting rod 2 and can slide along the axial direction of the top supporting rod 2 or be fixed by the locking member two 10. The bottom plate 1.1 can be adaptively provided with bolt holes for connecting the foundation outside the cup mouth 5 to stably arrange the device. The vertical plate 1.2 is used to provide a basic height for the stretchers 3 and the wedge-shaped plug 4, so that at least when the stretchers 3 are in the shortest state, the bottom surface of the wedge-shaped plug 4 is higher than the cup mouth 5, so as to facilitate the use and disassembly of the device. The vertical plate 1.2 can slide along the axial direction of the top supporting rod 2, so that the distance between the side support frame 1 and the wedge-shaped plug 4 can be changed to adapt to different working conditions, or the counterweight on both sides of the center of gravity of the top supporting rod 2 is adjusted to reduce the loss rate of the top supporting rod 2. Moreover, when the vertical plate 1.2 is sleeved on the top supporting rod 2, it is limited by the surrounding of the vertical plate 1.2, so that when the other end of the top supporting rod 2 is subjected to the tension generated by the stretching of the stretchers 3, the top supporting rod 2 remains in a horizontal state, so that the height of the top end of the stretchers 3 is always fixed, and the stretching can only make the wedge-shaped plug 4 rise and fall with the change of the height of the bottom end.

[0036] The locking member one 9 and the locking member two 10 can be selected as nuts, and the outer threads are adaptively arranged on the end portions of the auxiliary connecting rod 7 and the top supporting rod 2, and the outer diameters of the locking member one 9 and the locking member two 10 should be greater than the through holes of the auxiliary connecting rod 7 on the connecting block 8 and the through holes of the top supporting rod 2 on the vertical plate 1.2. In addition, the connecting block 8 can also be replaced by a steel plate commonly used in construction sites.

The plate part C4.3 forms an acute angle with the plate surface of the plate part B4.2, so that the device can be suitable for various working conditions. For example, the radial size of the cup mouth 5 and the radial size of the steel structure column 6 can be changed due to construction requirements, so the distance between the side walls of the two is not completely consistent in different working conditions. The plate part C4.3 is inclined, when the distance between the cup mouth 5 and the steel structure column 6 is small, the lower part of the plate part C4.3 can abut against the inner side wall of the cup mouth 5, and when the distance between the cup mouth 5 and the steel structure column 6 is large, the telescopic device 3 can be extended to make the upper part of the plate part C4.3 abut against the inner side wall of the cup mouth 5.
