Embodiment 1

[0038] Such as Figure 1-3 As shown, this embodiment provides a steel structure unloading device, including a support structure and an unloading structure. Wherein the support structure includes equal leg steel 2 symmetrically arranged on both sides of the web of the H-shaped steel column 1 and several layers of steel sheets 3 arranged on the equal leg steel 2 . The unloading structure includes a first corbel platform 4 and a second corbel platform 5 respectively vertically welded on the H-shaped steel column 1, and two screw jacks 6 are arranged on the upper surface of the first corbel platform 4, The two screw jacks 6 are symmetrically arranged relative to the H-shaped steel column 1, and a steel pipe 7 is arranged between the screw jack 6 and the second corbel platform 5, so that the load on the upper part of the node passes through the steel pipe 7 Pass to the screw jack 6.

[0039] The steel structure unloading device in this embodiment also includes a lateral stabilizi...

Embodiment 2

[0042] Such as Figure 4-6As shown, the steel structure unloading device in this embodiment includes a support structure and an unloading structure, wherein the support structure includes equal limb steel 2 symmetrically arranged on the web plates on both sides of the H-shaped steel column 1 and is arranged on the equal Several layers of steel sheets 3 on the limb steel 2; the unloading structure includes a first corbel platform 4 and a second corbel platform 5 respectively vertically welded on the H-shaped steel column 1, and the first corbel platform The upper surface of 4 is provided with two screw jacks 6, and the two screw jacks 6 are arranged symmetrically with respect to the said H-shaped steel column 1, and a screw jack 6 is arranged between the said second corbel platform 5 steel pipe 7, so that the load on the upper part of the node is transmitted to the screw jack 6 through the steel pipe 7.

[0043] The steel structure unloading device in this embodiment also incl...

Embodiment 3

[0048] The structural system adopts the pre-tensioned design of steel columns. Before pouring the concrete on the upper part of the pre-tensioned joints, in order to ensure the stability of the structural system, according to the requirements of the site, all butt steel columns are connected at the rear welding point except for the temporary connection of the ear plate with high-strength bolts. Welding is used, and then it is necessary to cut and unload the welding spot of the steel column before the steel column is stretched.

[0049] Such as Figure 7 As shown, the present embodiment provides a kind of unloading method that is used for cantilevered suspension building, there are four steel columns to be unloaded in the said cantilevered suspension building, and several welding points are arranged on each steel column, and described unloading method is specific Including the following steps:

[0050] 1. If Figure 8 As shown, establish the steel column position coordinate d...

Abstract

The invention discloses a demounting device and method for emptied and suspended buildings. The demounting device comprises a support structure and a demounting structure, wherein the support structure comprises equal-support leg steel and steel sheets, wherein the equal-support leg steel is arranged on two web plates of an H-shaped steel column, and the steel sheets are arranged on the equal-support leg steel; the demounting structure comprises a first bracket platform, a second bracket platform, helical jacks and steel pipes, wherein the helical jacks are arranged on the first bracket platform, and the steel pipes are arranged between the helical jacks and the second bracket platform. The demounting method includes numbering the steel columns and determining the demounting sequence of the steel columns; acquiring axial force data and deflection data of the steel columns; determining the model number of the jacks and the thickness of the steel sheets; setting up the demounting device at the welding joint positions of the steel columns; calculating and checking bearing capacity of the support structures and the demounting structures of the steel columns; cutting and demounting the welding joints of the steel columns according to the demounting sequence. The demounting device and method can demount the emptied and suspended buildings and has the advantages of convenience in operation and high safety.

Description

technical field [0001] The invention relates to the field of steel structures for buildings, in particular to an unloading device and method for hollow-suspended buildings. Background technique [0002] my country's annual urban and rural construction housing area is 2 billion square meters, and the energy consumption per unit building area in my country is more than twice that of developed countries. Concrete frame steel structures have been widely used in the construction field. In steel structure engineering, the unloading of steel structure is an indispensable operation link, which is the operation of the steel structure system's reliable transition from the support of the tire frame to the force of the structure body. The unloading in the traditional steel structure construction is to directly support the component through the jack, lower the jack one level, cut off the tire frame, lower it again, and cut it off until the tire frame is completely separated from the comp...
