Detailed ways

Please refer to Figures 1 to 5, the utility model discloses a jacking structure, including a first adjusting screw 30 and a first bracket 10; the first bracket 10 is arranged on the first adjusting screw 30; the The first adjusting screw 30 has two sections of threaded sections 31 that are arranged on the upper and lower sides of the first bracket 10, and each of the threaded sections 31 can be movably inserted into the external hollow column 60; The first adjusting parts 50 are screwed respectively, and each of the first adjusting parts 50 can be abutted against the end surface of the external column 60 .

On the basis of the above structure, when in use, the lower threaded section 31 is inserted into the outer column 60 and the lower first adjustment member 50 is abutted against the end face of the outer column 60, thus preventing the first adjustment screw 30 from moving relative to the outer column 60. The upright column 60 slides down to complete the installation of the jacking structure, and the first bracket 10 can be adjusted to a suitable elevation by rotating the first stopper to support the external main beam 110, and when it is necessary to add supports of different elevations , an additional external column 60 can be set outside the upper threaded section 31 and its end face can be offset against the upper first adjustment member 50 to prevent the additional external column 60 from sliding down. In this way, the existing adjustable jacking bracket can be used to insert Installed on the additional external column 60, at this time, the height of the existing external adjustable jacking bracket can be adjusted in conjunction with the rotation of the first adjusting member 50 below, so as to realize the support of different elevations; from above, there is no need to set the existing The cross buckle can prevent the cross buckle from colliding with the existing flower plate, which is beneficial to construction.

It is worth mentioning that the second adjusting member 82 plays the role of limit and height adjustment, and there is no need to separately arrange components to realize the limit and height adjustment, which simplifies the structure.

This embodiment also includes a connecting pipe 20 and a second bracket 40 arranged on the connecting pipe 20; the connecting pipe 20 can be sleeved outside the threaded segment 31, and the end surface of the connecting pipe 20 can be When the connecting pipe 20 is sleeved outside the upper threaded section 31 and abutted against the upper first adjusting member 50, the installation of the connecting pipe 20 and the second bracket 40 is completed. When the connecting pipe 20 is separated from the upper threaded section 31, the second bracket 40 and the connecting pipe 20 can be removed, which is convenient for disassembly and assembly; moreover, when the connecting pipe 20 is removed, the overall height of the jacking structure can be reduced, Conducive to storage and transportation; as mentioned above, the connecting pipe 20 and the second bracket 40 are arranged together, which is convenient to use.
