Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a sizing tool for a straight threaded joint of a main reinforcement of a cast-in-place pile. Background Art

[0002] Nowadays, bored piles are often used in building foundation and foundation pit support projects. Due to the long steel cage, it is often necessary to connect the hole mouth. The commonly used connection method is the main reinforcement lap welding. The main reinforcement diameter of the cast-in-place pile steel cage is generally large and the lap welding is vertical welding. The welding time is long and the technical level of the welder is relatively high. There is a quality risk of poor welding quality and the interval between the bored pile hole and the concrete pouring is too long, resulting in the collapse of the hole.

[0003] In order to avoid the quality risk of welding connection of the steel cage hole, another steel cage connection method is adopted, that is, straight thread sleeve connection. However, the steel cage of the whole pile is very long, and the size tolerance is small when the joint is connected with straight thread. When the two sections of the steel cage are connected, it is impossible to ensure that each joint is exactly matched, and the steel cage is not easy to adjust after forming, resulting in rework and delays in construction. Pre-assembly is often required during processing, which requires a large enough processing site, a long post-processing time, and is not very applicable to the construction site.

[0015] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0016] Reference Figures 1 to 3 The utility model is a sizing tool for straight threaded joints of main reinforcements of bored piles, which aims to solve the quality risks existing in the welding connection of bored pile steel cages, and at the same time solves the problem that the main reinforcements of steel cages are difficult to accurately align when the straight threaded sleeves of steel cages are connected. It has high practical and economic value, and specifically comprises two adjacent steel cages, wherein a reinforcing hoop 4 is arranged inside the steel cages to improve the strength of the steel cages, and an annular hoop 2 matching the diameter of the steel cages is arranged on one end of the two steel cages that are butted, and a plurality of sections of rulers 1 are installed on one side of the annular hoop 2, and the plurality of sections of the rulers are fixed by fasteners, and the position distribution of each section of the rulers along the direction of the main reinforcement 3 of the steel cages makes the end of each ruler flush with the end of the main reinforcement and fastened by the fasteners, and the synchronous butt connection of the ends of adjacent steel cages is achieved by the rulers.

[0017] The working steps of the utility model are as follows: after the first section of the steel cage (steel cage A) is processed, the annular hoop 2 of the sizing tool is adjusted to match the diameter of the steel cage;

[0018] Install the ruler 1 onto the annular hoop 2, the number of the ruler 1 being consistent with the number of the main bars 3 of the steel cage;

[0019] The ruler 1 is fixed to the annular hoop 2 by fasteners, and the position of the ruler 1 corresponds to the main reinforcement 3 of the reinforcement cage one by one;

[0020] Put the sizing tool on the steel cage, adjust the position of each ruler along the main reinforcement direction, make the end of each ruler 1 flush with the end of the main reinforcement 3, and fasten it with fasteners to keep the ruler position unchanged;

[0021] Remove the sizing tool from steel cage A. When processing the next section of steel cage (steel cage B), put the sizing tool on the first main bar of steel cage B, with the other end of the ruler flush with the main bar, and install the other main bars of steel cage B one by one, keeping each main bar flush with the other end of the ruler at the corresponding position;

[0022] After the main reinforcement of steel cage B and the reinforcement hoop of steel cage are all welded, the sizing tool is removed. At this time, one end of the sizing tool of steel cage A and one end of the sizing tool of steel cage B can be synchronously connected;

[0023] After the steel cage B is processed, put the sizing tool on the other end, adjust the ruler so that each end of the ruler is flush with each end of the main reinforcement, and tighten it;

[0024] Remove the sizing tool, put it on the next section of the steel cage, repeat the above steps, and repeat them back and forth to make the joints of each section of the steel cage perfectly connected.
