Description

Technical Field

[0001] The utility model specifically relates to a sleeve for concrete square column construction, belonging to the technical field of square column construction. Background Art

[0002] Columns made of reinforced concrete are the most basic load-bearing components in various engineering structures such as houses, bridges, and hydraulic engineering. They are often used as floor pillars, bridge piers, foundation columns, towers, and compression rods of trusses. Due to site limitations, it is difficult to use a static pile driver to construct concrete square columns. It is necessary to use a sleeve in combination with a steel sheet pile driver to replace the static pile driver, improve construction convenience, and reduce use costs. However, the existing sleeve is not convenient for fixing concrete square columns of different specifications, and its applicability is low.

[0003] As shown in the announcement number: CN217105085U, a sleeve for the construction of a concrete square column includes two side panels 1, two side panels 2 and a top plate, the two side panels 1 are parallel to each other, the two side panels 2 are parallel to each other, the side panel 1 connects the two ends of the side panel 2, the top plate connects the tops of the two side panels 1, the area surrounded by the side panels 1 and 2 is the same as the cross-sectional size of the concrete square column, the bottom of the side panel 2 is flush with the bottom of the side panel 1, the height of the side panel 2 is less than the height of the side panel 1, and the width of the top of the side panel 1 is less than the width of the bottom of the side panel 1. The utility model enables the concrete square pile to be directly constructed by a steel sheet pile driver through the sleeve, which greatly overcomes the site limitation factors and reduces the cost of pile foundation construction.

[0004] The above-mentioned sleeve for concrete square column construction is not convenient for fixing concrete square columns of different specifications and sizes when in use, and has low applicability. Utility Model Content

[0005] The purpose of the utility model is to provide a sleeve for concrete square column construction in view of the deficiencies in the prior art, so as to achieve the purpose of being able to fix square columns of different specifications, thereby improving the applicability of the utility model.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a sleeve for concrete square column construction, including a connecting sleeve, the inner wall of which is installed with adjustable fixing components arranged in an array for fixing the concrete square column, and a connecting piece is installed on the connecting sleeve.

[0007] Furthermore, in order to facilitate the installation of the adjustable fixing component, a sliding groove is provided on the inner wall of the connecting sleeve, and limiting holes are provided on the outer side of the connecting sleeve and on both sides of the sliding groove.

[0008] Furthermore, in order to facilitate the rotation of the bidirectional threaded shaft, the adjustable fixing assembly includes a bidirectional threaded shaft, the bidirectional threaded shaft is rotatably installed inside the sliding groove, and one end of the bidirectional threaded shaft extending to the lower end of the connecting sleeve is fixedly installed with an adjusting handwheel, and the bidirectional threaded shaft is rotated by rotating the adjusting handwheel.

[0009] Furthermore, in order to facilitate the movement of the sliding block, two sliding blocks are threadedly connected to the bidirectional threaded shaft, and the sliding block is slidably engaged in the sliding groove. The sliding block is threadedly connected to the bidirectional threaded shaft, and the sliding block moves when the bidirectional threaded shaft rotates.

[0010] Furthermore, in order to adjust the position of the fixed plate, a connecting rod is hinged on the sliding block, and the other end of the connecting rod is hinged with a hinged connecting seat, and a fixed plate is fixedly installed between the hinged connecting seats. By moving the sliding block, one end of the connecting rod moves to adjust the position of the fixed plate.

[0011] Furthermore, in order to facilitate the limiting of the fixing plate, limiting rods are installed on both sides of the fixing plate, the limiting rods are plugged into the limiting holes, and a circular limiting plate is fixedly installed on the other end of the limiting rods.

[0012] Furthermore, in order to increase the friction between the square columns, an anti-skid pad is installed on the fixed plate, and anti-sliding blocks arranged in an array are installed on the anti-skid pad.

[0013] Furthermore, in order for the steel sheet pile driver to clamp the utility model, a clamping groove is provided on one side of the connecting piece.

[0014] The technical effects and advantages of the utility model are as follows: the friction between the fixing plate and the square column is increased by the anti-slip pad and the anti-sliding block, so that the square column is fixed more tightly; the adjustable fixing component facilitates the fixation of square columns of different specifications and sizes, thereby improving the applicability.
