Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and more specifically, to a positioning clamp for the upper layer mesh of the foundation steel reinforcement. Background Technology
[0002] Pier cap construction plays a crucial role in bridge construction. With the comprehensive implementation of refined management and standardized construction, while ensuring construction quality, it is also necessary to further reduce costs, improve work efficiency, and optimize processes. In conventional pier cap construction, a single vertical reinforcing bar is welded together with two auxiliary reinforcing bars to support the upper reinforcing mesh, ensuring that the bottom and upper reinforcing meshes maintain the correct spacing.
[0003] However, this method of using one vertical reinforcing bar and two auxiliary reinforcing bars welded together requires a large number of vertical reinforcing bars or the erection of internal scaffolding, resulting in a large consumption of reinforcement and difficulties in dismantling. On the other hand, since the size of the foundation varies, the required reinforcement needs to be cut on a temporary basis; in order to ensure the stability of the reinforcement, a support system composed of vertical and auxiliary reinforcing bars is required, resulting in material waste.

[0034] Please refer to Figure 1 This embodiment provides a positioning clamp for the upper layer of steel reinforcement mesh in a foundation, including an upper support pipe 100, a lower support pipe 200, a rotating base 300, and fasteners 400.
[0035] The top of the upper support tube 100 has a top positioning groove 101 arranged in the radial direction; the lower support tube 200 can be sleeved on the outside of the upper support tube 100 so that the upper support tube 100 can move closer to or further away from the lower support tube 200; the fastener 400 can connect the upper support tube 100 and the lower support tube 200 respectively so that the upper support tube 100 and the lower support tube 200 are kept tight, or so that the upper support tube 100 and the lower support tube 200 can move relative to each other;
[0036] The bottom of the rotating base 300 has a bottom positioning groove 301 arranged in the radial direction; the rotating base 300 is horizontally rotatably mounted on the bottom of the lower support tube 200.
[0037] In this design, the lower support pipe 200 is supported on the bottom reinforcing mesh via a rotating base 300, while the upper support pipe 100 can rise and fall relative to the lower support pipe 200. The top of the upper support pipe 100 can be connected to the upper reinforcing mesh. The upper support pipe 100 and the lower support pipe 200 are kept relatively fixed by fasteners 400, ensuring that the upper reinforcing mesh is supported relative to the bottom reinforcing mesh to ensure the preset spacing. Furthermore, the top positioning groove 101 can be engaged with the reinforcing bars of the upper reinforcing mesh, and the bottom positioning groove 301 can be engaged with the reinforcing bars of the bottom reinforcing mesh, ensuring the stability of the connection between the positioning clamp and the reinforcing mesh. The rotating base 300 can rotate relative to the lower support pipe 200, ensuring that both the top positioning groove 101 and the bottom positioning groove 301 are engaged with the reinforcing bars, thus ensuring the stability of the positioning clamp connection. In summary, this type of upper reinforcing mesh positioning clamp for the foundation has a stable upper and lower reinforcing mesh support structure with accurate position and spacing. Meanwhile, to accommodate foundations of different heights, the positioning clamps for the upper layer of steel reinforcement mesh on the foundation are designed to be adjustable and modular.
[0038] Please continue reading. Figure 1 , Figure 2 and Figure 3 To understand more structural details of the positioning clamps for the upper layer of reinforcing steel mesh in the foundation, the upper support pipe 100 is made of steel pipe with an outer diameter of 4.8cm, and the lower support pipe 200 is made of steel pipe with an inner diameter of 5cm. The top of the upper support pipe 100 and the bottom of the rotating base 300 both have cross-shaped openings to facilitate reinforcing steel positioning.
[0039] from Figure 1 and Figure 2 As can be seen from the optional embodiment, the fastener 400 is a positioning pin; along the height direction of the upper support tube 100, a plurality of first through holes 110 are formed on the tube wall of the upper support tube 100; a second through hole 210 is formed on the tube wall at the top of the lower support tube 200; the positioning pin is sequentially inserted into the second through hole 210 and the first through hole 110 to ensure a tight fit between the upper support tube 100 and the lower support tube 200. This arrangement has the advantages of simple structure, convenient installation, and good positioning effect.
[0040] In an optional embodiment, the plurality of first through holes 110 are all located in the same straight line along the height direction of the upper support tube 100. This ensures that the upper support tube 100 and the lower support tube 200 can maintain a uniform adjustment of their relative height. Optionally, the plurality of first through holes 110 are arranged at equal intervals along the height direction of the upper support tube 100.
[0041] Please see Figure 1 and Figure 3 As shown in the figure, in the optional embodiment, the positioning clamp for the upper layer of the reinforcing mesh of the foundation also includes at least two limiting pins 500; a continuous annular groove 310 is provided on the peripheral wall of the rotating base 300 along the circumferential direction; symmetrical limiting through holes 220 are provided at the bottom of the lower support pipe 200, and the limiting through holes 220 are arranged along the radial direction of the lower support pipe 200; the number of limiting pins 500 and limiting through holes 220 are the same, and they are arranged in a one-to-one correspondence; one end of the limiting pin 500 passes through the limiting through hole 220, and the other end extends into the annular groove 310. Through the cooperation of the limiting pins 500 and the annular groove 310, the rotating base 300 can rotate relative to the lower support pipe 200, thus ensuring that the top positioning groove 101 and the bottom positioning groove 301 can be engaged in the reinforcing bars of the corresponding mesh, thereby ensuring the stability of the clamp.
[0042] In an optional embodiment, the positioning fixture for the upper layer of the reinforcing steel mesh in the foundation also includes a support bearing 600. One end of the support bearing 600 is connected to the bottom of the lower support tube 200, and the other end of the support bearing 600 can be connected to the rotating base 300 to support the rotation of the rotating base 300 relative to the lower support tube 200. The support bearing 600 ensures the flexibility of the relative rotation of the rotating base 300 and the lower support tube 200. Optionally, the support bearing 600 is a plane bearing.
[0043] In an optional embodiment, a boss 230 is provided on the inner wall of the bottom of the lower support tube 200, the top of the plane bearing abuts against the bottom of the boss 230, and the bottom of the plane bearing abuts against the rotating base 300.
[0044] In use, the lower support tube 200 is used to clamp onto the reinforcing bars of the bottom reinforcing mesh; the upper support tube 100 is used to clamp onto the reinforcing bars of the upper reinforcing mesh. The height of the clamps is adjusted by inserting fasteners 400 through the first through holes 110 at different heights, thus securing the upper reinforcing mesh. After the upper reinforcing mesh is installed, the clamps are removed and the mesh is taken out.
[0045] Furthermore, after the bottom layer of the foundation steel mesh is installed, the bottom of the clamp is fixed to the bottom layer of the foundation steel mesh through the cross opening of the lower support pipe 200. Then, the height of the clamp is adjusted according to the height of the upper steel mesh. Specifically, the second through hole 210 on the lower support pipe 200 is connected and fixed to the first through hole 110 on the upper support pipe 100 using fasteners 400. Multiple positioning clamps are arranged in a staggered pattern in the foundation at 4m intervals in both the horizontal and vertical directions. Horizontal steel bars are installed in the cross opening of the upper support pipe 100 as supporting steel bars. Longitudinal steel bars are installed on top of the upper support pipe according to design requirements, and outer door bars and horizontal steel bars are installed on the horizontal steel bars. Finally, the uprights are installed. After welding some of the uprights to the upper and lower layers of steel mesh to form a whole, the fasteners 400 are removed, the relative height of the upper support pipe 100 and the lower support pipe 200 is shortened, and the positioning clamps are removed and reused for the next foundation construction.
[0046] In summary, this utility model embodiment provides a positioning clamp for the upper layer of steel mesh in a foundation cap, which has at least the following advantages:
[0047] The clamp height is adjusted using a horizontal pin hole, which is convenient and stable to operate.
[0048] The rotating base 300 can rotate relative to the lower support tube 200, so that the top positioning groove 101 and the bottom positioning groove 301 are both inserted into the steel bars to ensure the stability of the positioning clamp connection.
[0049] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
