Description

Technical Field

[0001] This utility model relates to a construction tool for circular structural columns, specifically an integrated tool for circular column formwork and back bracing. Background Technology

[0002] Cylindrical formwork is an essential component and technology in cast-in-place concrete structure engineering, while back ribs are an essential reinforcement component for wall and column formwork. Currently, cylindrical formwork and back ribs are two separate devices, which leads to serious waste, complicated construction, and inconvenient use. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an integrated tool for cylindrical formwork and backing, suitable for the construction of circular structural columns. It serves as both cylindrical formwork and backing during construction, and is achieved through the following technical solution:

[0004] A cylindrical template and back rib integrated tool includes a quarter-circular arc steel plate, arc steel plate reinforcing bars, arc angle steel, long side angle steel, and short limb reinforcing bars. Seven arc steel plate reinforcing bars are welded to the back of the quarter-circular arc steel plate. The arc steel plate reinforcing bars are spaced one-eighth of the arc length apart. Several short limb reinforcing bars are set between the arc steel plates and the arc angle steel. Long side angle steels are connected to the long sides of the quarter-circular arc steel plate.

[0005] A further preferred technical solution is that the quarter-circular arc steel plate is 1.5m long and 3mm thick, and the radius of the circle is the same as the radius of the cylinder.

[0006] A further preferred technical solution is that the arc angle steel is a drilled angle steel of model L30 with a side length equal to the radius of the cylinder.

[0007] A further preferred technical solution is that the long side angle steel is a drilled angle steel of model L30 with a length of 1.5m.

[0008] A further preferred technical solution is that the arc angle steel is welded at intervals of 200-300mm.

[0009] The integrated cylindrical template and backing tool of this utility model can be used as both a cylindrical template and a backing tool, and has the advantages of stable structure, easy to carry, quick assembly and disassembly, and economic practicality. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 2-3 As shown in the preferred embodiment, a cylindrical template and backing rib integrated tool is provided, including a quarter-circular arc steel plate 1, arc steel plate reinforcing bars 2, arc angle steel 3, long-side angle steel 4, and short-limb reinforcing bars 5. First, four quarter-circular arc steel plates 1, each 1.5 meters long and 3 mm thick, with a radius consistent with the radius of the cylinder, are fabricated. Seven φ10 arc steel plate reinforcing bars 2, each 1.5 meters long, are welded to the back of the arc steel plates 1, with a spacing of one-eighth of the arc length. Then, a tool is fabricated to match the cylinder... An L30-radius drilled arc angle steel 3 and a 1.5-meter-long L30-radius drilled long-side angle steel 4 are used, with drill holes spaced 10cm apart. The arc angle steel 3, with its equal radius to the cylinder, is welded to the arc steel plate 2 using several φ10 short-limb steel bars 5, with welds every 200-300mm. The 1.5-meter-long long-side angle steel 4 is welded to the two long sides of a quarter-circle arc steel plate 1, thus obtaining the integrated cylindrical template and back rib tool of this utility model. In use, as... Figure 1 As shown, four cylindrical templates and back rib integrated tools are connected by hexagonal bolts and nuts 6 to form a whole, which is then used as cylindrical templates and back rib tools.

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
