A Quick Method for Removing Vertical Support

Abstract

The invention discloses a method for rapidly removing a vertical support. The method includes the following steps that (1) a flat supporting plate is mounted under the vertical support; (2) the flat supporting plate is supported by a rolling supporting foot which comprises a fence, an upper end plate and a lower end plate, wherein the upper end plate and the lower end plate are welded inside the fence, the upper surface of the upper end plate is lower than the top surface of the fence, a plurality of steel balls I are distributed all over the upper surface of the upper end plate, and the top elevation of the steel balls I is higher than the top elevation of the fence; the lower surface of the lower end plate is higher than the bottom surface of the fence, a plurality of steel balls II are distributed all over the lower surface of the lower end plate, the bottom elevation of the steel balls II is lower than the bottom elevation of the fence, and a cavity formed by the upper end plate, the lower end plate and the fence is filled with rigid filler; and the flat supporting plate is supported by the steel balls I, and the steel balls II are supported on the ground; and (3) the vertical support is rapidly removed by dragging the rolling supporting foot. By means of the method, the vertical support can be quickly and safely removed, and the cost is low.

Description

technical field [0001] The invention relates to a method for quickly removing vertical supports, and more particularly, the invention relates to a method for dynamically and instantly removing vertical supports for large structures. Background technique [0002] In order to study the performance of some structures or meet the needs of some design and construction, it is necessary to quickly remove the vertical support of the structure. Current methods for quickly removing vertical supports are very difficult to implement. For example, pre-embedding explosives in vertical support members, although this method can be achieved instantaneously, is very dangerous, and the shock wave of the explosion will produce a short-term upward force on the upper structure, which is not in line with expectations; The method of the hinge mechanism aims to achieve the effect of quick removal of the support by bending a part of the vertical support member, but the instability of the hinge itsel...

The current method of quickly removing vertical supports is very difficult to implement

For example, pre-embedding explosives in vertical support members, although this method can be achieved instantaneously, is very dangerous, and the shock wave of the explosion will produce a short-term upward force on the upper structure, which is not in line with expectations; The method of the hinge mechanism aims to achieve the effect of quick removal of the support by bending a part of the vertical support member, but the instability of the hinge itself increases the risk, and the pin used for fixing in the early stage bears the burden. If the upper load is very large, the sliding friction force is too large, which makes it difficult to pull out and the bending mechanism is difficult to realize; there are also some methods that use electromagnetic principles to control the position of the vertical support member, which can quickly remove the vertical support member. support, but the cost is high, the requirements for the working environment are high, and the installation and design are difficult

Other methods that use cranes or jacks to control have improved safety, but due to the restrictions on the use of machinery, the process of removing vertical supports is slow and cannot be removed quickly.
