[0003] One is to use a steel horse stool to bear, and then use a rope saw to cut the support beam in sections. The steel horse stool made by this method is heavy, difficult to set up, and needs to be made on site according to the distance between the support beam and the floor, which cannot be recycled between projects, and even needs to be re-made when the support beam of different layers is dismantled, so the material cost is high and recycling is difficult.
[0004] Two is to set up a steel pipe frame to bear, and then dismantle the internal support beam. The frame set up by this method cannot actively bear the load of the support beam, and when the rope saw cuts off the support beam, the frame may suddenly bear a large load due to sudden stress change, which may cause instability and has certain safety hazards.

[0007] Further, the module interface comprises an outer pipe and an inner pipe in nested cooperation.
[0008] Furthermore, the outer side of the inner tube is provided with multiple vertical protrusions; the inner side of the outer tube is provided with multiple vertical grooves; the protrusions and grooves of the nested outer tube and inner tube are interlocked.
[0009] Furthermore, the end of the outer tube is provided with a tongue and groove corresponding to the position of the groove.
[0010] Furthermore, there are at least two main modules, and at least two of the main modules have different heights.
[0011] Furthermore, the load-bearing module also includes a top support and a load-bearing section; the jack is disposed between the top support and the load-bearing section; the top support supports the support beam; the load-bearing section is connected to the main module through the module interface.
[0012] Furthermore, the support module includes a support section and a support base plate disposed at the bottom of the support section; the support section is connected to the main module through the module interface.
[0013] Furthermore, the support module also includes a support armhole; multiple support armholes are provided on the outer side of the support section, and the support armholes are connected to the support base plate.
[0014] The beneficial effects of this utility model include: the support device adjusts its height by connecting several main modules, and then fine-tunes the position of the top support by using the jacks of the bearing module, making it suitable for dismantling internal support beams at various heights; the support beam rests inside the top support, and the bearing module, main module, and support module are connected as a whole through module interfaces; the overall installation process of the support device is simple and convenient, easy to operate, and can be reused after use, with the advantages of convenient installation, reusability, strong stability, flexible adjustment, and the ability to actively bear the load of the support beam.

Support haunch 402 is welded at the connection between support section 401 and support base plate 403. One is set in each of the four directions to increase the lateral resistance of support module 4.
[0029] Supporting crossbeam 1 rests in the top support 201 of the two end support device bearing module 2, the lower part of the top support 201 is welded with the jack 202, the jack 202 is welded with the bearing section 203, the bearing section 203 is sequentially downward main body module 3, the modules are butted through the module interface 6; the main body module 3 is butted with the support module 4 below, the support section 401 bottom of the support module 4 is welded with the support bottom plate 403, and the welding place is provided with support haunch 402 on four sides.
