Supporting mechanism for unloading building structural member and use method thereof

Abstract

The invention discloses a supporting mechanism for unloading a building structural member and a use method thereof; the supporting mechanism comprises four stressed inclined rods, a pulled cross rod, an upper end plate and a lower end plate, wherein the first stressed inclined rod and the second stressed inclined rod are respectively connected with the upper end plate in a rotating way; the first stressed inclined rod and the third stressed inclined rod are connected with each other in a rotating way; the second stressed inclined rod and the fourth stressed inclined rod are connected with each other in a rotating way; the third stressed inclined rod and the fourth stressed inclined rod are respectively connected with the lower end plate in a rotating way; threads are arranged on the external surfaces of two ends of the pulled cross rod; one end of the pulled cross rod penetrate out of the connecting part of the first stressed inclined rod and the third stressed inclined rod; the other end of the pulled cross rod penetrates out of the connecting part of the second stressed inclined rod and the fourth stressed inclined rod; and two ends of the pulled cross rod are respectively provided with nuts. The use method of the supporting mechanism comprises the following steps of: (1) connecting the supporting mechanism and a supported surface of a structure; and (2) applying a supporting force of the supported surface of the structure by the supporting mechanism. Through the adoption of the supporting mechanism and the use method disclosed by the invention, the safe unloading of the structural member can be ensured.

Description

technical field [0001] The present invention relates to a component used in the field of construction and its use method, in particular to a support mechanism for unloading building structural components and its use method. Background technique [0002] In actual engineering, it is often necessary to strengthen and transform the structure. During the reconstruction process, in order to eliminate the adverse effect on the reinforcement effect caused by the stress lag of the reinforced components, or to avoid the lack of bearing capacity of adjacent components caused by the change of the force transmission path after the components are removed, it is necessary to unload and then strengthen the reconstruction. At present, the commonly used unloading methods include angle steel support method, vertical pole support method, joist replacement method and so on. The joist replacement method does not set supports, but applies prestress to the upper beam of the column to be unloaded ...

AI Technical Summary

Problems solved by technology

The angle steel support method is widely used in construction, and part or all of the force borne by the columns is borne by the angle steel, but it has the disadvantages of difficult construction and affecting the force of other components of the original structure; the vertical pole support comes from bridge engineering and is an angle steel support. A kind of optimization, the bottom is equipped with a jacking bracket, which can adjust the vertical rod up and down, but there are also disadvantages that the supporting force is not easy to apply, and the device cannot be reused
