Temporary support device and construction method for combined inclined column of frame steel structure

Abstract

The invention discloses a temporary support device for a frame-type steel-structure combined oblique stand column and a construction method. The device comprises rails (1) fixed to oblique stand column single body (2), and a trolley (3) is arranged on the rails (1); the oblique stand column monomers (2) are hinged to oblique support rods (4); the trolley (3) is provided with an electromotor (6) connected with a worm (17), a frame is provided with a worm gear (18) matched with the worm (17), and a support sleeve (19) is fixed to the worm gear (18); the side of the frame is slidably matched with a connecting plate (8) which is in threaded connection with the rails (1). The method is characterized by comprising the steps that the trolley (3) is pushed to get close to the oblique stand column monomers (2) to enable stress clamping rings (5) arranged on the lower portions of the oblique support rods (4) to abut against an opening of the support sleeve (19) of the trolley (3), and then the trolley (3) is in threaded connection with the rails (1). According to the device and method, assembly and disassembly are both convenient to operate, and the labor intensity can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of building frame steel structure construction, in particular to a temporary support device for a combined inclined column of a frame steel structure of a building and a combined inclined column for constructing a frame steel structure using the temporary support device. Column method. Background technique [0002] With the rapid development of my country's steel structure construction industry, various complex and special-shaped space structures are widely used in various buildings, realizing various visual effects of special facade shapes for buildings. However, although the above-mentioned special-shaped space structures have different shapes, they are generally realized based on the conventional column-beam frame structure combined with inclined columns. The conventional column-beam frame structure can be constructed according to the conventional method. Discuss the construction of oblique columns, espe...

Problems solved by technology

[0005] The temporary support device and construction method of the combined oblique column in 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 phases Adjacent units need to be assembled and fixed by bolts, and they need to be dismantled one by one when dismantling, which is labor-intensive, slow construction speed, and low efficiency; moreover, the lantern-type steel truss requires a large number of steel pipe fasteners, which consumes a lot of materials and costs; Moreover, a lantern-type steel truss needs to be erected at the junction of every two oblique columns. In order to construct a combined oblique column, multiple lantern-type steel trusses need to be erected, which is labor intensive, low in construction efficiency, and consumes a large amount of steel pipes and fasteners; of course, some people consider moving the truss integrally constructed from the previous oblique column to the joint of the next oblique column, but the height of the integral truss is the same as that of the next oblique column. The single column does not match, and it is still necessary to add a truss unit on the top to increase the height, which belongs to high-altitude operations, and it is still very troublesome to operate, and the integral truss is too heavy, and it is very laborious to carry and move, which is very inconvenient
