Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a unloading system and a unloading method for a steel structure herringbone brace. Background Art

[0002] During the construction of high-rise steel structures, herringbone braces are often used to provide support for the upper structure. A support falsework needs to be set at the bottom of the herringbone brace to provide auxiliary support for the herringbone brace and ensure the stability of subsequent structure construction. After the subsequent steel structures are successively constructed and the herringbone brace is stable, the support falsework at the bottom needs to be unloaded and removed. In traditional construction practices, the method of directly removing the support falsework is adopted. This method is prone to structural instability due to sudden changes in load during unloading, and the safety is poor. Summary of the Invention

[0012] A second cushion block for supporting the bottom of the herringbone brace, and the second cushion block is connected to the top of the second spherical hinge support.

[0013] A further improvement of the unloading system of the steel structure herringbone brace of the present invention lies in that an anti-slip pad is connected to the top of the second cushion block.

[0014] A further improvement of the unloading system of the steel structure herringbone brace of the present invention lies in that a scale is marked on the piston rod of the jack.

[0015] A method for unloading a steel structure herringbone brace includes the steps:

[0016] Step 1: Provide the unloading system of the steel structure herringbone brace as described in claim 1;

[0017] Step 2: Synchronously control the elongation of multiple replacement braces until they abut against the bottom of the herringbone brace;

During each section of contraction, the state of the herringbone brace is monitored at all times using a level and an angle gauge. After each section of contraction is completed, it is paused for at least 10 minutes and the stability of the herringbone brace is monitored.

[0023] Compared with the prior art, the advantages of the present invention are as follows:

[0024] By providing replacement braces to replace the support of the herringbone brace, the stable removal of the support members is ensured.

[0039] like Figure 6 As shown: a plurality of the support-changing members 4 and a plurality of the support members 2 are interlaced.

[0040] Specifically, a scaffold 5 for supporting the ground is connected to the bottom of the supporting tire frame 1 .

[0041] By supporting the scaffold 5 on the ground, a connection foundation is provided for the supporting tire frame 1.

[0042] Preferably, the support member 2 comprises:

[0043] A vertically arranged column 201, wherein the column 201 is detachably connected to the top of the tire support frame 1;
