A construction method for removing devices for inner braced beams and replaced braced beams

Abstract

The invention discloses a construction method for an inner support beam and a support beam removal device, which comprises a middle frame body and side frame bodies symmetrically and fixedly connected to both sides of the middle frame body, the height of the middle frame body is higher than that of the side frame bodies, The side frame body is provided with a slideway along the width direction of the inner support beam. The cutting device is installed on the slideway and slidably connected with the side frame body. The bottom of the middle frame body is equipped with a driving wheel, which can drive the removal device to move. The middle frame body The bottom is provided with a telescopic column and a multi-functional bracket, and the bottom of the telescopic column is provided with buckles, and a supporting steel beam is arranged between the buckles. The multi-functional bracket is also scalable, and the bottom of the multi-functional bracket is provided with rollers. The invention does not need to set up a supporting frame body, fully automatic operation, good safety performance, movable and other performances, and the support dismantling device can be used repeatedly, which better solves the safety technical problems existing in the dismantling process of the foundation pit, and the inner support beam is dismantled Integration with hoisting greatly improves construction safety performance and construction efficiency.

Description

technical field [0001] The invention relates to the technical field of brace replacement construction, in particular to a device and construction method for removing an inner brace beam and a brace replacement beam. Background technique [0002] With the expansion and use of the large underground space, the supporting structure system of the underground space is complex and changeable. Correspondingly, during the construction of the main structure of the basement and the demolition of the supporting structure, it is necessary to carry out the construction of dismantling and replacing the supporting structure, and some of the main structure needs to be replaced. As a supporting structure, some need to add a temporary supporting structure according to the specific situation to meet the safety and stability of the foundation pit construction. At present, in the support structure system of deep and large foundation pits, the enclosure structure is generally located outside the m...

AI Technical Summary

Problems solved by technology

At present, in the support structure system of deep and large foundation pits, the enclosure structure is generally located outside the main structure of the basement and permanently buried underground, while the inner support beams are mostly made of reinforced concrete structures, and the inner support structures generally need to be removed after the construction of the support structure is completed. The construction of the next process can be carried out, which is also an important process in the construction of the entire foundation pit. During the removal of the inner support beam, the conventional method is to erect the support frame. The support frame is generally two types of steel support frame and steel pipe support frame. The erection of the support frame often requires a large number of support frame materials and installation operators. After the installation is completed, the frame inspection and acceptance are required. The risk of construction safety is relatively high, and a large number of supporting frame materials need to be spliced ​​and combined, resulting in large material loss and long construction period
