Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a supporting device for construction of building steel structures. Background Art

[0002] During the steel structure construction process, some steel components need to be temporarily supported so that the subsequent construction process can continue. In the existing construction industry, the supporting devices used are mostly temporarily built pipe racks for support.

[0003] The current support device for steel structure building construction, as described in the patent with publication number CN220133589U, comprises: a pillar, fixed blocks are fixedly connected on both sides of the pillar, a support rod is hinged on the fixed block, a pair of No. 1 telescopic rods are arranged at the bottom of the pillar, a clamping plate is arranged at the bottom of the No. 1 telescopic rod, one end of the support rod away from the fixed block is clamped in the clamping plate, a buffer mechanism is arranged at the bottom of the clamping plate, and an adjustment mechanism is arranged. The adjustment mechanism includes a threaded rod rotatably connected to the bottom of the pillar, a rotating rod is arranged at the bottom of the pillar, the rotating rod passes through the bottom of the pillar and is fixedly connected to the threaded rod, and a nut is threadedly connected to the threaded rod.

[0004] With respect to the above-mentioned related technologies, the existing support device for steel structure building construction adjusts the height of the pillar by shaking the screw rod when in use. However, due to the limited length of the screw rod and the triangular shape of the support rod and the connecting rod, the height of the pillar lifted by the support rod is relatively low, so that the overall support range of the device is limited, resulting in low practicality. It cannot be used for supporting some higher structures. At the same time, as a supporting structure, a spring is used at the bottom for buffering, resulting in the formation of elastic support at the bottom, which reduces the supporting capacity. Utility Model Content

[0005] The purpose of the utility model is to provide a supporting device for building steel structure construction to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A support device for building steel structure construction, comprising: a support column and a lifting structure; the lifting structure is arranged inside the support column, and the lifting structure includes a lifting column inserted into the support column, teeth uniformly welded on the outer wall of the lifting column, an adjustment box welded on the outer wall of the lifting column, a gear rotatably connected to the inner wall of the adjustment box, a rotating handle welded on one end of the gear extension part and a limit bolt threadedly connected to the outer wall of the support column, and the gear is meshed with a row of teeth.

[0008] By adopting the above technical solution, by inserting a lifting column of the same length into the inside of the support column, unscrewing the limit bolt and shaking the rotating handle, the gear rotation can be used to drive the teeth to move up and down, so that the height of the lifting column can be adjusted inside the support column, and the limit bolt can be tightened to prevent the rotating handle from rotating. The lifting structure adopted by the device increases the range of support height adjustment, and support can also be provided under a higher structure, thereby improving the practicality of the device support use.

[0009] Preferably, a base is provided at the bottom end of the support column, and a pressurizing structure is provided inside the base. The pressurizing structure includes a second slide groove opened on the inner wall of the base, a second clamping strip welded on the outer wall of the support column, and a foot-operated hydraulic cylinder arranged inside the base, and the top of the foot-operated hydraulic cylinder is connected to the bottom of the support column by bolts.

[0010] By adopting the above technical solution and adding a pressurizing structure to the bottom of the support column, the foot-operated hydraulic cylinder can be extended to support the bottom of the support column, so that the support column can move upward, so that the lifting column can fully act on the bottom of the building for pressurized support, thereby forming mutual pressure among the ground, the device and the building, thereby improving the supporting strength and effect of the device and reducing the probability of loosening and collapse due to insufficient supporting pressure.

[0011] Preferably, the four inner walls of the base are all provided with second slide grooves, the four outer walls of the support column are all welded with second clamping strips, and the second clamping strips are inserted into the second slide grooves.

[0012] By adopting the above technical solution, the bottom of the support column can be stably moved in the base by inserting the second clamping strip into the second sliding groove, thereby improving the stability of the support column when it is lifted or lowered.

[0013] Preferably, a first clamping strip is welded to the inner wall of the support column, a first sliding groove is formed on the outer wall of the lifting column, and the first clamping strip is inserted into the first sliding groove.

[0014] By adopting the above technical solution, by inserting the first clamping strip into the first sliding groove, the lifting column can be limited by the first sliding groove, so that the lifting column can only move in the vertical direction, avoiding the movement during lifting and lowering that affects the support effect.

[0015] Preferably, a support seat is welded to the bottom of the base, an insertion hole is opened on the outer wall of the support seat, and a support plate is inserted into the inside of the insertion hole.

[0016] By adopting the above technical solution, the support plate is assembled by plugging, and the upper support plate can be assembled when support is needed to increase the bottom force area and improve the support stability. At the same time, after disassembly, the space occupied by the device can be greatly reduced, which is convenient for transportation and storage of the device.

[0017] Preferably, the position of the limit bolt is within the circle of the rotating handle, and the adjustment box and the gear are located on the top of the support column.

[0018] By adopting the above technical solution, by screwing the limit bolt within the circle of the rotating handle, the cross structure in the rotating handle can be blocked after roughly adjusting the appropriate height. When the lifting column is driven back by the downward force to rotate the gear, the downward force can be offset by the rotation of the blocking rotating handle, so that the lifting column is firmly positioned at the designated position to support the building.

[0019] Preferably, the lower surface of the support plate is stepped, and the lower surface of the outer end of the support plate is flush with the lower surface of the support seat.

[0020] By adopting the above technical solution and using a stepped support plate for plug-in assembly, the support seat can be flush with the bottom of the support plate, fully exerting force on the ground to disperse the force and improve the stability during support.

[0021] Preferably, an outer wall of the base is provided with a movable hole, and a foot pedal of the foot-operated hydraulic cylinder extends out from the movable hole.

[0022] By adopting the above technical solution, a foot-operated hydraulic cylinder is installed internally, and the telescopic rod is extended by repeatedly stepping on the foot pedal externally using the movable hole. The maximum length ensures the supporting structure of the base without affecting the normal use of the foot pedal.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] (1) By inserting a lifting column of the same length into the support column, unscrewing the limit bolt and shaking the rotating handle, the gear rotation can be used to drive the teeth to move up and down, so that the height of the lifting column can be adjusted inside the support column. When the limit bolt is tightened, the rotation of the rotating handle can be blocked. The lifting structure adopted by the device increases the range of the support height adjustment, and can also provide support under a higher structure, thereby improving the practicality of the device support;

[0025] (2) By installing a pressure structure at the bottom of the support column, the foot-operated hydraulic cylinder can be extended to support the bottom of the support column, so that the support column can move upward, so that the lifting column can fully act on the bottom of the building for pressure support, so as to form mutual pressure between the ground, the device and the building, which can improve the support strength and effect of the device and reduce the probability of loosening and collapse due to insufficient support pressure;

[0026] (3) By assembling the support plate in a plug-in manner, the support plate can be assembled when support is needed to increase the bottom force-bearing area, improve the support stability, and solve the problem of unstable elastic support with springs in the existing structure. At the same time, after disassembly, the space occupied by the device can be greatly reduced, which is convenient for transportation and storage of the device. BRIEF DESCRIPTION OF THE DRAWINGS
