Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly to an in-round-column positioning hoop for steel bars. Background Technique

[0002] In previous building projects, the displacement problems of steel bars in circular columns were relatively common. These displacement phenomena mainly included lateral displacement, displacement towards the outside of the frame column, and the inclination of steel bars. Lateral displacement and displacement towards the outside of the frame column may cause changes in the thickness of the main reinforcement protective layer, thereby affecting the durability and safety of the structure. The inclined state of the steel bars may change their force paths and reduce their bearing capacity. For this reason, we propose an in-round-column positioning hoop for steel bars. Summary of the Invention

[0003] Aiming at the deficiencies existing in the prior art, the utility model provides an in-round-column positioning hoop for steel bars that can be reused, is convenient to install, and has accurate positioning.

[0004] The technical solution of the utility model to solve the above problems is:

[0005] An in-round-column positioning hoop for steel bars, characterized in that: it includes a circular frame, positioning steel bars, transverse reinforcement members, and longitudinal reinforcement members. A number of pairs of parallel positioning steel bars are annularly distributed inside the circular frame. Two parallel longitudinal reinforcement members are provided at the upper part of the circular frame, and two parallel transverse reinforcement members are provided at the lower part, or two parallel transverse reinforcement members are provided at the upper part of the circular frame, and two parallel longitudinal reinforcement members are provided at the lower part. The two transverse reinforcement members and the two longitudinal reinforcement members jointly form a "well"-shaped reinforcement structure; strip-shaped holes are respectively provided at both ends of the transverse reinforcement members and the longitudinal reinforcement members, and the transverse reinforcement members and the longitudinal reinforcement members are fixed by bolts passing through the corresponding strip-shaped holes.

[0006] Further, the circular frame is formed into a circle by processing and welding steel bars.

[0007] Further, the net distance between each pair of positioning steel bars is the diameter of the main reinforcement of the circular column plus 2 - 5 mm.

[0008] Further, the length of the positioning steel bars is the diameter of the main reinforcement of the circular column plus 1 - 10 mm.

[0009] Further, the number of pairs of positioning steel bars is determined according to the number of main reinforcements of the circular column.

[0010] Further, both the transverse reinforcement members and the longitudinal reinforcement members are made of steel plates with a thickness of 10 mm and a width of 20 mm, and the strip-shaped holes are opened with a length of 150 mm and a width of 10 mm.

[0011] The circular frame of the utility model is clamped and fixed by transverse reinforcement members and longitudinal reinforcement members, with good overall stability, high rigidity, accurate positioning, which can effectively control the spacing of the main reinforcement bars of circular columns, prevent problems such as deviation of the main reinforcement bars and uneven spacing, ensure the installation quality of the main reinforcement bars of circular columns, reduce the construction cost, and improve the construction efficiency.

[0016] Embodiment, as Figure 1 and Figure 2 shown, the positioning hoop 5 includes a circular frame 1, positioning steel bars 2, transverse reinforcement members 3, longitudinal reinforcement members 4, strip holes 8 and bolts 9. Among them, the circular frame 1 is welded into a circle by steel bars; several pairs of parallel positioning steel bars 2 are annularly distributed inside the circular frame 1, and the positioning steel bars 2 are welded and fixed to the circular frame 1; there are two transverse reinforcement members 3 and two longitudinal reinforcement members 4, and strip holes 8 are opened at both ends. The transverse reinforcement members 3 are installed at the lower part of the circular frame 1, and the longitudinal reinforcement members 4 are installed at the upper part of the circular frame 1, intersecting and perpendicular to each other to form a "well"-shaped reinforcement structure. The transverse reinforcement members 3 and the longitudinal reinforcement members 4 are fixed by bolts 9 passing through the corresponding strip holes 8.

[0017] As Figure 2 shown, the main reinforcement bars 6 of the circular column are arranged between each pair of positioning steel bars 2 inside the circular frame 1, and the main reinforcement bars 6 of the circular column and the positioning hoop 5 are fixed by wire binding; the positioning hoop 5 can be made of the remaining steel bars and the edge materials of steel plates generated during the construction process, with low cost; after the concrete of the circular column 7 solidifies to a certain strength, the positioning hoop 5 can be removed and reused.

[0018] During the installation or disassembly process, the positioning hoop 5 can slide vertically along the main reinforcement bars 6 of the circular column. There is a certain gap between the positioning steel bars 2 and the main reinforcement bars 6 of the circular column, making the installation and disassembly of the positioning hoop 5 more convenient, reducing the jamming between the positioning hoop 5 and the main reinforcement bars 6 of the circular column. Further, the clear distance between each pair of positioning steel bars 2 is the diameter of the main reinforcement bars 6 of the circular column plus 2 - 5 mm.

[0019] In this embodiment, to ensure the positioning effect of the positioning steel bars 2 on the main steel bars 6 of the circular column, the circular frame 1 and the positioning steel bars 2 are made of HRB335 or HRB400 grade steel bars; the diameter of the steel bars of the circular frame 1 is ≥14 mm, and the diameter of the positioning steel bars 2 is ≥10 mm; the length of the positioning steel bars 2 is the diameter of the main steel bars 6 of the circular column plus 1 - 10 mm.

[0020] In this embodiment, the number of pairs of the positioning steel bars 2 is determined according to the number of the main steel bars 6 of the circular column, that is, the number of the positioning steel bars 2 is twice the number of the main steel bars 6 of the circular column.

[0021] In this embodiment, both the transverse reinforcement member 3 and the longitudinal reinforcement member 4 are made of steel plates with a thickness of 10 mm and a width of 20 mm, the bolts 9 are of M8.0 specification, and the size of the elongated holes 8 is 150 mm in length and 10 mm in width.

[0022] The circular frame 1 of the present utility model is clamped and fixed by the transverse reinforcement member 3 and the longitudinal reinforcement member 4, and has good overall stability, large stiffness, accurate positioning, can effectively control the spacing of the main steel bars 6 of the circular column, prevent problems such as deviation of the main steel bars and uneven spacing, improve the construction efficiency, and ensure the installation quality of the main steel bars 6 of the circular column.
