Description

Technical Field

[0001] The utility model relates to the technical field of steel cage manufacturing, and particularly relates to a device for quickly positioning the spacing of main steel bars of a circular column. Background Technique

[0002] With the rapid development of modern society, the foundation engineering construction of various industries such as municipal, water conservancy, and construction will all involve the construction of circular columns. During the construction of circular columns (cast-in-place pile steel cages), it is necessary to quickly position the spacing of the main steel bars. At present, the traditional method for manufacturing most pile body steel cages is to use a hoop bending machine to process the steel bars into inner ring stiffening hoop rings according to the design drawings, and then weld them with the main steel bars at intervals to form a cage. Finally, the spiral stirrups are welded to the outside of the main steel bars. When manufacturing the inner ring stiffening hoop rings by this process, the forming effect is relatively poor, and there are often phenomena such as the stiffening hoops being non-circular and non-smooth. Moreover, when welding with the main steel bars, it is necessary to manually measure the spacing of the main steel bars one by one with a tape measure, the operation is cumbersome and redundant, the cumulative error is large and it is easy to make mistakes, which affects the forming quality of the steel cage.

[0026] Specific Embodiment 1 of the device for quickly positioning the pitch of the main reinforcement bars of a circular column provided by the present utility model:

[0027] Please refer to Figure 1-4, A device for quickly positioning the spacing of main reinforcement bars of a circular column, including a positioning body 1 with a circular edge, and a number of pairs of positioning grooves 2 for positioning the main reinforcement bars 9 evenly distributed on the circular edge of the positioning body 1; in this embodiment, the shape of the positioning body 1 is an annular plate, and the positioning grooves 2 are grooves formed by cutting from the edge of the positioning body 1, which can clamp the main reinforcement bars 9 and accurately position the main reinforcement bars 9.

[0028] In this embodiment, the positioning body 1 is formed by connecting a number of arc-shaped plates end to end, the edges of adjacent arc-shaped plates overlap and are connected by bolts 5; first connection holes 6 for cooperating with the bolts 5 are provided at the edges of the arc-shaped plates. Two first connection holes 6 are provided at both ends of the edge of the arc-shaped plate, and two adjacent arc-shaped plates are connected by two bolts 5. The positioning body 1 is formed by connecting a number of arc-shaped plates through bolts 5 and can be disassembled. After the main reinforcement bars of the steel cage are shaped, the positioning body 1 can be disassembled and taken out from the steel cage.

[0029] In this embodiment, the number of arc-shaped plates forming the positioning body 1 is three. Since the edges of the arc-shaped plates are stacked and connected end to end, there is an axial gap between the first end of the first arc-shaped plate and the tail section of the last arc-shaped plate. Therefore, in this embodiment, a lining plate 7 is provided. The lining plate 7 is located between the first end of the first arc-shaped plate and the tail end of the last arc-shaped plate. Second connection holes 8 for the bolts 5 to pass through are provided on the lining plate 7, and the number of the second connection holes 8 is two.

[0030] In order to keep the main reinforcement bars 9 at the lower part and both sides of the positioning body 1 in position and not fall off after positioning, and without the need for manual continuous support of the main reinforcement bars 9, a number of hook bodies 3 are provided in this embodiment. The first end of the hook body 3 is hooked to the main reinforcement bar 9, and the second end is hooked to the positioning body 1. Specifically, the hook body 3 includes an intermediate rod portion 31. A hook portion 32 for hooking to the main reinforcement bar 9 is integrally connected to the first end of the intermediate rod portion 31, and a bent portion 33 for hooking to the positioning body 1 is integrally connected to the second end of the intermediate rod portion 31; the plane where the bending of the hook portion 32 is located is perpendicular to the plane where the bending of the bent portion 33 is located. A number of hanging holes 4 for cooperating with the bent portions 33 are provided on the positioning body 1. The hanging holes 4 correspond to the positioning grooves 2 one by one, and the hanging holes 4 are located inside the corresponding positioning grooves 2.

[0031] After placing the main reinforcement bar 9 at the positioning groove 2, hook the hook portion 32 of the hook body 3 outside the main reinforcement bar 9, make the bent portion 33 correspond to the hanging hole 4, and then move the hook portion 32 along the axial direction of the main reinforcement bar 9 to make the bent portion 33 enter the hanging hole 4, so as to realize the hooking connection between the hook body 3 and the positioning body 1. As Figure 2 shown in the state, the outer limit of the main reinforcement bar 9 can be realized. As Figure 1 shown, the main reinforcement bars 9 at the upper part of the positioning body 1 do not need to be hooked by the hook bodies 3. When disassembling after the steel cage is formed, first remove the hook bodies 3, and then disassemble the positioning body 1 to take out the arc-shaped plates.

[0032] In a certain section of a project, the land area is approximately 117,700 m², and the foundation pit area is approximately 79,500 m². The foundation pit support design is a support structure with high-pressure jet grouting piles added between the support piles. There are a total of 1,221 support piles. The diameter of the first row of cast-in-place piles on the roadside is 1.8 meters, and the diameter of the second row of cast-in-place piles on the roadside is 1.5 meters. The pile forming method is all rotary drilled cast-in-place piles. To accelerate the construction progress and ensure the construction quality, this embodiment is tested in this project, which can solve the problem of poor forming effect of the main reinforcement and stirrups of the cast-in-place pile, make the positioning of the main reinforcement accurate and stable, eliminate the redundant work of repeated measurement, avoid the quality defect problem caused by cumulative error, and effectively ensure the one-time forming quality of the steel reinforcement cage.

[0034] Please refer to Figure 5 and Figure 6 , the difference between this embodiment and Embodiment 1 is that: in Embodiment 1, the positioning groove 2 is formed by cutting at the edge of the positioning body 1, while in this embodiment, two limiting strips are connected to the edge of the positioning body 1, and a positioning groove 2 is formed between the two limiting strips.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions recorded in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features.
