[0002] With the continuous development of the construction industry, the structural forms of buildings are becoming more and more diversified, and steel structures are being used more and more widely in various types of buildings. Therefore, safety measures in the process of steel structure installation are of paramount importance. In the hoisting construction of steel structures, the concrete top plate and concrete beams are overloaded and cracked due to the stacking of construction materials or the movement of car cranes on the concrete top plate. It is necessary to adopt the top support measures as the support system of the basement top plate during the construction stage. Top plate concrete beams will also encounter such conditions in general engineering construction.

[0003] At present, the support of beams and slabs is still mostly based on the traditional fastener-type full-span steel pipe frame or disc-type full-span frame for temporary top support. However, this type of full-span support evenly distributes the floor load to the lower slab surface through multi-point support. Not only is the construction cumbersome and time-consuming, but it also occupies a large amount of basement space, which has a great impact on the subsequent construction and personnel passage of the basement.

[0004] Therefore, developing a temporary support device for beams and slabs that occupies a small area, has a stable supporting structure and is easy to disassemble later is a technical problem to be solved. Utility Model Content

[0005] Due to the above-mentioned defects in the prior art, the utility model provides a detachable temporary support device for beams and slabs to solve the problem that the traditional support device occupies a large space and takes a long time to construct.

[0010] The side walls of the outer tube and the inner tube are symmetrically provided with a plurality of pairs of limiting holes; the second screw rod passes through the limiting holes of the inner tube and the outer tube transversely and is fastened by a second nut.

[0011] The size of the steel plate, the inner tube, the outer tube and the specifications of their fasteners are selected to match the required maximum bearing capacity to serve as the load-bearing parts of the temporary support device at the bottom of the beam and slab. When installing the temporary support device, first reserve the sleeve, then install the steel plate, the inner tube, the outer tube in sequence, then install the screw pre-tightening device for pre-tightening, and finally tighten the inner tube and the outer tube through the second screw and its kit to form a stable structure.

[0012] Furthermore, the first nut is used in conjunction with a first gas washer.

[0013] Furthermore, the second nut is used in conjunction with a second gas washer.
