A construction support device

Abstract

The present invention proposes a support device for building construction, which includes a support rod, the surface of the support rod is provided with a rectangular external thread, and the side of the rectangular external thread facing away from the lower end of the support rod is provided with first positioning points spaced along its helical direction. part; it also includes a quick-adjusting barrel sleeved on the support rod, the inner wall of the quick-adjusting barrel is provided with a rectangular internal thread adapted to the rectangular external thread, and the side of the rectangular internal thread facing the lower end of the support rod is provided with a The second positioning parts are arranged at intervals, the pitch of the rectangular external thread and the rectangular internal thread is greater than the tooth width, so that when the quick-adjusting cylinder is stressed toward the lower end of the support rod, the first positioning part and the second positioning part are engaged with each other to make the The quick adjustment cylinder realizes circumferential positioning, and when the quick adjustment cylinder is stressed towards the upper end of the support rod, the first positioning part and the second positioning part are separated from each other, so that the quick adjustment cylinder rotates to adjust the axial position of the quick adjustment cylinder on the support rod. The invention has the advantages of fast adjustment speed, long service life and good supporting performance.

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to a building construction support device. Background technique [0002] In building construction, supports are often used to support the formwork, so that cement can be poured on the formwork, such as the ceiling of the house, stairs, etc., most of the current supports are wood supports, and they are often used in different positions or in actual use. The height of the support is different in different occasions, so in many cases, when the height of the wood support is not enough, you can only superimpose bricks on the ground. Wooden boards and other materials are used to increase the height, which leads to messy construction ground and poor support strength, which is prone to tilting and overturning. At the same time, it is extremely inconvenient to disassemble and assemble, which brings great trouble to the construction. Contents of the invention [0003] Based o...
