Inclined throwing support dip angle adaptive supporting device

Abstract

The invention discloses an inclined throwing support inclination angle adaptive supporting device which comprises a base plate, an angle adjusting clamping support and a supporting component. The base plate is connected with the bracket support, and the bracket support is arranged on a foundation pit wall waist beam or the bottom of a foundation pit. One end of the angle adjusting clamping support is connected with the base plate rotating shaft and rotates relative to the base plate so as to adjust the opening angle between the base plate and the supporting component. The supporting component is in direct contact with the inclined throwing and supporting steel pipe and used for restraining the position of the inclined throwing and supporting steel pipe and bearing loads transmitted by the steel pipe. The angle adjusting clamping and supporting structure is provided with a plurality of gears, the proper gear can be selected according to the inclination difference condition of the bracket support face, the top face of the inclined throwing and supporting steel pipe makes full contact with the supporting face of the supporting plate component, the purpose of fully playing the top supporting effect of the inclined throwing and supporting is achieved, and the construction quality of the inclined throwing and supporting structure is guaranteed; and meanwhile, the construction period prolonging caused by design change redoing can be avoided, and obvious invention significance is achieved for foundation pit engineering.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to the installation and erection of an oblique throwing support structure in foundation pit construction. Background technique [0002] The foundation pit support system involves the interaction between soil and support. Foundation pit construction, especially in densely built areas, will be constrained by existing structures such as surrounding buildings (structures) and underground pipelines, which has higher requirements on the supporting capacity and overall stiffness of the supporting system. It can provide sufficient and stable support for the foundation pit, ensure the safe and convenient construction of the pit, and effectively control the deformation and displacement of the soil at the bottom of the pit, outside the pit and behind the wall, and ensure that the surrounding buildings (structures) and The normal operation of existing underground facilities.
