Description

Technical Field

[0001] This utility model belongs to the field of positioning frame technology, and in particular relates to a rebar cage positioning frame for interlocking piles. Background Technology

[0002] With the development of urban infrastructure, especially the large-scale construction of subways, each subway station requires a foundation pit during construction. Foundation pits usually require retaining piles, which are mostly interlocking piles. This is a new type of retaining technology in the field of foundation pits. Due to its lower cost and shorter construction period compared to diaphragm walls, it is rapidly growing in ultra-deep foundation pits and projects with high environmental protection requirements. In particular, the emergence of double-layer interlocking piles (both the first and second sequence piles contain steel cages) and the design of anchoring the pile top into the capping beam has added stronger competitiveness to interlocking piles. However, the design of anchoring the pile top into the capping beam also puts forward higher requirements for on-site construction, because the retaining piles need to be anchored into the top slab and capping beam as permanent structures. Because it needs to be connected to the capping beam and top slab later, the direction of the steel cage cannot be as unrestricted as before (the direction of the round cage can be arbitrary in the past). The step side of the steel cage needs to be fixed to face the inside of the foundation pit. Especially in the process of lowering the cage for the first-order piles in the interlocking pile project, because it is a square steel cage and the second-order piles need to be constructed on both sides later, the positioning of the first-order pile steel cage must be accurate and the orientation of the cage is also extremely demanding.

[0003] Currently, the positioning of the rebar cage on site relies on markings made on the casing with an angle grinder. During the lowering of the rebar cage, its positioning and orientation are controlled by manual measurement and calibration. This method is not only time-consuming and labor-intensive, but also has limited accuracy. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a rebar cage positioning frame for interlocking piles, so as to better improve the construction quality and efficiency and improve the positioning accuracy of the rebar cage.

[0005] The purpose of this utility model is achieved through the following technical solution: a rebar cage positioning frame for interlocking piles includes a rectangular frame, with clamps fixed at the four corners of the bottom of the rectangular frame. The inner ring formed by the four clamps is fitted onto the upper end of the outer circumferential wall of the steel casing. Limiting units for limiting the square rebar cage are provided on the two opposite inner sidewalls of the rectangular frame, and positioning units aligned with the directional positioning lines on the steel casing are provided on the inner sidewall of the rectangular frame.

[0006] The beneficial effects of this utility model are as follows: Compared with the prior art, by setting a rectangular frame and setting a clamp on the frame, the positioning frame can be positioned with the steel casing. In addition, a limiting unit is set in the frame to limit the square steel cage. The positioning unit facilitates alignment with the directional positioning line on the steel casing. The square steel cage lowered by this positioning frame can effectively ensure the positioning accuracy and directional angle, thereby improving the construction quality and efficiency.

[0007] Preferably, the rectangular frame is a square frame, and the outer diameter of the rectangular frame is smaller than the outer diameter of the steel casing. The four clamping plates are distributed at a 45° angle to the four corners of the rectangular frame. With the above structure, the rectangular frame can be stably placed on the upper end of the steel casing.

[0008] Preferably, the center of the clamping plate is provided with a through hole that intersects with the through hole provided at the top of the steel casing; this can prevent displacement after the positioning frame is placed, and improve the stability after placement.

[0009] Preferably, the limiting unit includes four limiting blocks, and two of the limiting blocks are provided on each of the two opposite inner sidewalls of the rectangular frame. The four corners of the square steel cage are limited between the four limiting blocks. The corner limiting can effectively restrict the displacement and rotation of the square steel cage, thereby ensuring positioning accuracy and direction angle.

[0010] Preferably, the positioning unit includes four grooves, all of which are located at the center of the four sides of the inner wall of the rectangular frame; this makes it easier to align the positioning frame with the steel casing, thereby further improving the positioning accuracy and orientation angle of the square steel cage inside the steel casing.

[0011] Preferably, hooks are provided at the top four corners of the rectangular frame to facilitate the hoisting and relocation of the positioning frame. Attached Figure Description
