It should be understood that the dimensions, proportions and numbers of elements in the drawings are not intended to limit the present application.

But this application provides a but quick assembly disassembly's temporary support for solving the inconvenient problem of adjacent tubular column dismouting of temporary support among the prior art.

As shown in fig. 1 and 2, a temporary support 1 according to an embodiment of the present application includes a plurality of pipe columns 10 that are butted end to end, an upper flange 11 is disposed at an upper end of the pipe column 10, a lower flange 12 is disposed at a lower end of the pipe column 10, corresponding slots 50 are formed at peripheries of the upper flange 11 and the lower flange 12, bolts 20 are rotatably disposed at the slots 50 on the upper flange 11, a position limiting plate 40 is penetrated on the bolt 20, a nut 30 is screwed, a clamping edge 121 is formed at a periphery of the lower flange 12, the bolt 20 is turned upwards to enter the slot 50, and the position limiting plate 40 is pressed inside the clamping edge 121 by the nut 30.

It should be noted that, in the prior art, two adjacent upper and lower pipe columns are connected by flanges, and the fixed connection of the flanges is to sequentially pass a plurality of bolts through two butted flanges and then tighten nuts on the bolts, thereby completing the connection between the two pipe columns.

According to the temporary support capable of being quickly disassembled and assembled, the problem of how to improve the disassembling and assembling convenience of the upper and lower two adjacent tubular columns is solved through the cooperative matching of the clamping groove, the bolt, the limiting plate and the nut.

Specifically, the temporary support 1 is formed by splicing a plurality of pipe columns 10 which are butted end to end in the vertical direction, each pipe column 10 has the same configuration, an upper flange 11 is fixedly connected to the upper end of each pipe column 10, a lower flange 12 is fixedly connected to the lower end of each pipe column 10, the upper flange 11 and the lower flange 12 are coaxially arranged with the pipe column 10, corresponding clamping grooves 50 are formed at the peripheries of the upper flange 11 and the lower flange 12, the clamping grooves 50 are arranged along the radial direction of the pipe columns 10, meanwhile, the clamping grooves 50 are uniformly distributed along the circumferential direction of the pipe columns 10, the clamping grooves 50 form spaces for placing the bolts 20, and the width of the clamping grooves 50 is equal to the outer diameter of the bolts 20.

Bolt 20 has been arranged at draw-in groove 50 department on last flange 11, pivot 21 has rotationally been arranged at the lower surface of last flange 11, the tip fixed connection of bolt 20 is on pivot 21, bolt 50 can overturn in draw-in groove 50, under the natural state, bolt 20 is in the state of dangling, namely the free end of bolt 20 is vertical down, after upwards overturning 180 degrees (the biggest upset limit), bolt 20 can the joint in draw-in groove 50, and keep vertical state up, the axis of tubular column 10 is located bolt 20's upset plane.

When the lower flange 12 of the previous pipe column 10 is abutted with the upper flange 11 of the next pipe column 10, and the clamping grooves 50 on the lower flange 12 and the upper flange 11 are aligned, at this time, after the bolt 20 is turned over, the bolt 20 is located in the clamping space formed by the two clamping grooves 50, and simultaneously, the bolt 20 is higher than the lower flange 12.

A limiting plate 40 is arranged on the bolt 20 in a penetrating manner, and the nut 30 is screwed together, wherein the nut 30 is closer to the free end of the bolt 20, i.e. the limiting plate 40 is located between the rotating shaft 21 and the nut 30, the limiting plate 40 is configured to be arc-shaped plate-shaped as a whole, a through hole 41 is configured on the limiting plate 40, the bolt 20 passes through the through hole 41, and the limiting plate 40 can freely slide on the bolt 20.

The periphery of the lower flange 12 protrudes upwards to form a clamping edge 121, the clamping edge 121 is integrally configured to be annular and is coaxially arranged with the lower flange 12, the clamping groove 50 forms a notch on the clamping edge 121, the outer arc surface of the limit plate 40 is matched with the inner circumferential surface of the clamping edge 121, when the bolt 20 keeps a vertically upward state, the limit plate 40 is just clamped on the inner circumferential surface of the clamping edge 121, at the moment, the limit plate 40 can be tightly pressed on the inner circumferential side of the clamping edge 121 of the lower flange 12 by screwing the nut 30, and the bolt 20 is prevented from sliding out of the clamping groove 50.

In order to avoid the interference between the nut 30 and the locking edge 121, the thickness of the position limiting plate 40 is greater than the height of the locking edge 121.

It should be noted that, when the bolt 20 is turned upwards to maintain a vertical state, the bolt 20 abuts against the bottom of the slot 50, and meanwhile, the outer arc surface of the position-limiting plate 40 abuts against the inner circumferential surface of the locking edge 121, so that the vertical degree of the bolt 20 is ensured.

Although embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present application.
