Adjustable support and its construction method

Abstract

The invention provides an adjustable support and a construction method thereof. The adjustable support is arranged between a basement ceiling and the ground and is formed by a main force transfer component, the upper part of the main force transfer component is connected with an adjustable head component, the lower end of the main force transfer component is connected with a load dispersing component, the main force transfer component comprises a vacancy filling part, a jack ejector rod on a jack ejector base of the main force transfer component is in contact connection with the adjustable head component which has a linear upward movement trail on the main force transfer component, the vacancy filling part consists of four valve ring vacancy blocks, the inner diameter and the outer diameter of the vacancy filling part are equal to those of the main force transfer component, the vacancy filling part is inlaid between the main force transfer component with the adjusted supporting height and the adjustable head component. All parts are prefabricated in a factory, and are assembled, adjusted, fixed and erected in site. The adjustable support assists large-scale overhang steel structures or large-span steel structure in constructing, so that the tedious condition of overlapping a scaffold is avoided; the height of the head component of the adjusted support is adjustable, so that the problem that supporting stand columns cannot be erected due to the fact that the absolute length of the supporting stand columns is greater than the interlayer spacing of a basement is solved; the adjustable support can be conveniently detached, transferred and reused.

Description

technical field [0001] The invention relates to a structural support component and a construction method thereof, in particular to an adjustable support arranged in a basement for transferring loads of a large-scale cantilevered steel structure or a long-span steel structure and a construction method thereof. Background technique [0002] Large-scale cantilevered steel structures or long-span steel structures generally require a support system to assist in construction (loading or unloading), and the support should be set on the foundation of the building that is compatible with the support point. In reality, in order to pursue more efficient use of land, modern buildings are equipped with basements, so that the support points cannot be directly set on the foundation. In order to solve this kind of situation, it is usually used to set up a full-scale scaffolding support system to assist in the construction of large-scale cantilevered steel structures or long-span steel struc...

In reality, in order to pursue more efficient use of land, modern buildings are equipped with basements, so that the support points cannot be directly set on the foundation

In order to solve this kind of situation, it is usually used to set up a full-scale scaffolding support system to assist in the construction of large-scale cantilevered steel structures or long-span steel structures. Setting up a full-scale scaffolding support system is not only time-consuming, labor-intensive, and resource-consuming, but also the erection accuracy and support The contact surface needs to be strictly controlled, and the control process is difficult
