Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a column construction device. Background Art

[0002] At present, in bridge construction projects, the common method of casting columns is to set up scaffolding outside the columns. Workers stand on the scaffolding to cast the columns. This method has two main disadvantages: 1. The construction time is long. Each column needs to be cast separately. The scaffolding needs to be dismantled after the column casting is completed. This will make the dismantling very troublesome, consume a lot of manpower and construction costs, and also extend the construction period. 2. The site requirements are high. The scaffolding needs a relatively flat and solid site and a certain amount of erection space. When the site conditions are limited, the site needs to be handled separately, which greatly increases the construction cost and also extends the construction period. Utility Model Content

[0003] The utility model aims to overcome the deficiencies in the prior art and to provide a column construction device in order to solve the shortcoming that a scaffolding needs to be separately set up for column casting.

[0004] The purpose of the utility model is achieved through the following technical scheme. The column construction device includes a column formwork and a work platform. A support frame is provided on the top peripheral wall side of the column formwork, and at least two support frames are provided on each side wall of the column formwork. The work platform is installed on the support frame by bolt fixing, and the work platform is distributed in a surrounding manner on the top peripheral wall side of the column formwork, and the platform surface of the work platform is lower than the top surface of the column formwork; the upper and lower adjacent column formworks are fixed in an overlapping manner and vertically along the columns to be cast, and the upper and lower ends of the column formwork are provided with surrounding purlins, and the end corners between the circumferentially adjacent column formworks are fixed by the surrounding purlins and using surrounding purlin clamps, and the support frame is fixed on the sides of the upper and lower ends of the surrounding purlins of the column formwork located at the top.

[0005] The beneficial effects of the utility model are as follows: compared with the prior art, by adopting the above-mentioned structural setting, the working platform and the column formwork can be installed and removed at the same time, which saves the time of separately setting up and removing the working scaffolding. At the same time, there is no need to occupy the ground area, and the installation can be completed on the column formwork.

[0006] Preferably, the purlin is composed of two channel steels and fixed to the upper and lower ends of the column formwork by welding. The two channel steels are distributed with their backs facing each other, and wedge-shaped connecting blocks with through holes are provided at the two end corners of the purlin. The purlin clamp includes tension screws, gaskets and nuts. The tension screws pass through the wedge-shaped connecting blocks and are placed in gaskets and are tightened with nuts to fix the circumferentially adjacent column formworks. Through the arrangement of the above structure, the stability of the circumferential column formworks after fixation is better, and the stability of the working platform is also greatly enhanced, and the safety performance is greatly improved.

[0007] Preferably, the support frame is formed by three angle steels which are welded in a triangular distribution; such a structure is not only simple in structure but also makes the installed working platform more stable.

[0008] Preferably, the working platform includes an operating platform bracket, a patterned steel plate and a handrail frame. The operating platform bracket is installed on the support frame by bolt fixing, the handrail frame is installed on the outer edge of the operating platform bracket, and the patterned steel plate is laid on the operating platform bracket. The working platform arranged by the above structure makes disassembly and assembly more convenient.

[0009] Preferably, the operating platform bracket and the handrail frame are each provided with four pieces, and the adjacent operating platform brackets are fixed by bolts and distributed in a surrounding manner on the top outer wall side of the column formwork, and the adjacent handrail frames are fixed by bolts and distributed in a surrounding manner on the outside of the working platform; through the above-mentioned structural arrangement, the operating platform bracket and the handrail frame are more convenient to disassemble and assemble.

[0010] Preferably, one side of the patterned steel plate abuts against the bottom side wall of the handrail frame, and the other side of the patterned steel plate abuts against the outer peripheral wall of the column formwork; the patterned steel plate can play an anti-slip role, thereby improving the safety of construction workers during operation, and at the same time abuts against the bottom side wall of the handrail frame and the outer peripheral wall of the column formwork, further improving the safety of construction workers during operation and preventing the risk of falling.
