Temporary support device and temporary support method for oblique column of building steel structure

Abstract

The invention discloses a temporary support device and temporary support method for an inclined column of a building steel structure. The device comprises a track (1), wherein one end of the track (1) is fixed with the bottom end of the inclined column (2); the track (1) is provided with a trolley (3); the trolley (3) is hinged to an inclined support rod (4); a trolley frame is provided with a tilt angle adjusting air cylinder (5) and a winch (8); a traction rope (10) of the winch (8) bypasses a fixed pulley (9) to be fixed with a basket (11); the trolley frame is matched with a connection plate (13) which is used for being in screw joint with the track (1) in a sliding manner. The key of the method is that the trolley (3) is pushed to approach the inclined column (2), the trolley (3) is in screw joint with the track (1), and a worker goes up by the basket (11), and the tops of the inclined column (2) and the inclined support rod (4) are fixed. Both the device and the method are convenient in mounting and dismounting, and can be used for effectively reducing the labor intensity, improving the construction speed, improving the efficiency, reducing the amount of consumables and lowering the cost.

Description

technical field [0001] The invention relates to the technical field of building steel structure construction, in particular to a temporary support device and a temporary support method for inclined columns of a building steel structure. Background technique [0002] In modern steel structure buildings, in order to create a special facade shape effect, large oblique columns are often designed in the steel structure. The bottom end of the inclined column is fixed on the ground, and the upper end is fixed to the completed cross beam or floor slab in the steel structure. [0003] And the construction method of the oblique column of prior art is, earlier the upper end of oblique column is lifted with crane, then the bottom of oblique column is fixed with the ground, as fixing a steel base plate with screw on ground, then oblique column and The steel base plate is fixed by welding or bolting. At this time, the upper end of the inclined column is suspended by multiple suspension r...

AI Technical Summary

Problems solved by technology

[0004] The temporary support devices and temporary support methods of the prior art have the following defects: First, the assembly and disassembly process of the lantern-type steel truss is too troublesome, and it needs to be erected unit by unit from the ground up, and every two adjacent units They all need to be screwed together and fixed, and they need to be dismantled one by one when dismantling, which is labor-intensive, slow in construction speed, and low in efficiency; moreover, the lantern-type steel truss requires a large number of steel pipe fasteners, which consumes a lot of materials and costs high; of course, some people Considering the installation and disassembly of the integral type, but the height of the integral truss generally does not match the inclined column, it is still necessary to add or subtract truss units at the top to adjust the height, which belongs to high-altitude operations, and it is still very troublesome to operate, and the integral type The truss is too heavy, it is very inconvenient to carry and move
