Description

A prefabricated placement rack for pipe pile reinforcing cages Technical Field

[0001] This application relates to the field of pipe pile construction, and in particular to a prefabricated placement frame for pipe pile reinforcement cages. Background Technology

[0002] Pipe piles are foundation engineering components consisting of a steel cage and concrete. When making pipe piles, the steel cage is usually assembled first, and then the steel cage is placed in a mold or pile hole for concrete pouring. After the concrete solidifies, it becomes an integral part of the steel cage, and the pipe pile is then completed.

[0003] At construction sites of large infrastructure projects, assembled steel cages are typically placed in batches next to the construction area. After the pile holes are formed, the steel cages are then hoisted into the pile holes using hoisting equipment. A placement rack is set up next to the construction area, and the steel cages are stacked on the rack. Since the length of each steel cage is horizontal, the placement rack has upward-opening arc grooves. Once the steel cages are placed in these arc grooves, they remain stable.

[0004] A common placement rack is a long frame welded from several steel pipes, forming multiple arc grooves along its length. The arrangement of these arc grooves is perpendicular to the axis of the reinforcing cage. When a large number of reinforcing cages are required, a large number of arc grooves are needed, resulting in a long and flat rack that is not conducive to handling or storage. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a prefabricated placement rack for pipe pile reinforcement cages.

[0006] The technical solution provided in this application for a prefabricated placement frame for pipe pile reinforcement cages is as follows:

[0007] A prefabricated placement frame for pipe pile reinforcement cages includes a frame body with multiple arc grooves along its length. The frame body includes multiple placement unit frames, which are arranged along the length of the frame body. Each arc groove is located on a placement unit frame, and adjacent placement unit frames are movably connected.

[0008] Preferably, the length direction of the arc groove is horizontal, a connecting shaft is provided between two adjacent placement unit frames, the placement unit frames and the connecting shaft are rotatably connected, the length direction of the connecting shaft is vertical, the relative rotation angle between two adjacent placement unit frames is 180°, the frame also includes a support frame, the support frame and the placement unit frame are detachably connected, and the support frame abuts against the ground.

[0009] Preferably, the edge of the placement unit frame is fixedly connected with a connecting sleeve, the connecting sleeves between two adjacent placement unit frames are staggered and coaxial with each other, and the connecting shaft passes through each connecting sleeve and is threadedly connected to one of the connecting sleeves.

[0010] Preferably, when the arc grooves on two adjacent placement unit frames are both placed into the reinforcing cage, there is a support gap between the two adjacent placement unit frames. The support frame is located within the support gap. The support frame includes an upright and a crossbar. The middle part of the crossbar is fixedly connected to one end of the upright. The length direction of the crossbar is parallel to the axis of the arc groove. The side of the crossbar away from the upright is flush with the bottom of the placement unit frame. The two opposite parts of the upright are in contact with the two placement unit frames respectively.

[0011] Preferably, a connecting bolt is simultaneously threaded through two adjacent placement unit frames, and the connecting bolt is threadedly connected to the upright.

[0012] Preferably, the placement unit frame has a positioning groove on the side facing the support gap, the length direction of the positioning groove is parallel to the axis of the arc groove, and a positioning protrusion is fixedly connected to the upright, and the positioning groove allows the positioning protrusion to slide into.

[0013] Preferably, the placement unit frame has a storage hole, a storage protrusion is fixedly connected to the placement unit frame, and a storage groove is provided on the side of the crossbar away from the upright. After the storage protrusion enters the storage groove, the storage hole and the threaded hole on the upright are aligned.

[0014] This application includes at least one of the following beneficial technical effects:

[0015] 1. Through the interconnection of multiple placement unit frames, the frame itself is a relatively flexible deformable structure, which can be unfolded when placing the steel cage and deformed to reduce its length when transporting or storing it, thereby improving the convenience of operation and reducing spatial obstacles;

[0016] 2. By setting up the support frame, the support frame provides lateral support to the frame after it is unfolded, improving the stability of the frame when it is placed on the ground. After the frame is folded down, the support frame is installed on the placement unit frame for storage through the storage protrusion and storage hole, which improves the overall integrity of the components in the stored state.

Detailed Implementation

[0020] The present application will be further described in detail below with reference to Figures 1-2.

[0021] This application discloses an assembly-type placement frame for reinforced concrete pile cages, as shown in Figures 1 and 2. The frame includes a frame body 1, which comprises multiple placement unit frames 2 and multiple support frames 3. Adjacent placement unit frames 2 are detachably connected. Each placement unit frame 2 has a semi-circular arc groove 12. The frame body 1 has two states: unfolded and retracted. When unfolded, the placement unit frames 2 are oriented in a specific direction, and the axes of the arc grooves 12 are parallel to each other, allowing the reinforced concrete cage to be placed horizontally within the arc grooves 12. When retracted, the placement unit frames 2 are stacked, and the axes of the arc grooves 12 coincide. The support frames 3 are used to support the placement unit frames 2 in the unfolded state.

[0022] As shown in Figure 1, the length direction of the arc groove 12 is horizontal. Two connecting sleeves 21 are fixedly connected to the edge of the placement unit frame 2. The axis of the connecting sleeves 21 is vertical. The connecting sleeves 21 between two adjacent placement unit frames 2 are staggered and coaxial with each other. A connecting shaft 22 is provided between two adjacent placement unit frames 2. The connecting shaft 22 passes through each connecting sleeve 21 and is threadedly connected to one of the connecting sleeves 21. That is, multiple placement unit frames 2 are sequentially rotated and connected through the connecting shaft 22 and the connecting sleeves 21. From the unfolded state to the stored state, the relative rotation angle between two adjacent placement unit frames 2 is 180°.

[0023] As shown in Figure 1, in the unfolded state of the frame 1, there is a support gap 11 between two adjacent placement unit frames 2. The support frame 3 includes an upright 31 and a crossbar 32. The middle part of the crossbar 32 is fixedly connected to one end of the upright 31. The length direction of the crossbar 32 and the upright 31 are perpendicular. A triangular rib plate is welded and fixed between the upright 31 and the crossbar 32. The upright 31 of the support frame 3 is located within the support gap 11. The length direction of the upright 31 is vertical. The length direction of the crossbar 32 is parallel to the axis of the arc groove 12. A positioning groove 23 is provided on the side of the placement unit frame 2 facing the support gap 11. The length direction of the positioning groove 23 is parallel to the axis of the arc groove 12. A positioning protrusion 33 is fixedly connected to the upright 31, and the positioning groove 23 allows the positioning protrusion 33 to slide into it. When the upright 31 is located within the support gap 11 and the positioning protrusion 33 is located within the positioning groove 23, the two opposite sides of the upright 31 are in contact with the two placement unit frames 2 respectively. The side of the crossbar 32 away from the upright 31 is flush with the bottom of the placement unit frame 2. The support frame 3 is used to improve the stability of the placement unit frame 2 when it is placed on the ground after being unfolded. A connecting bolt 34 is simultaneously passed through two adjacent placement unit frames 2. The connecting bolt 34 is threaded to the upright 31. The length direction of the connecting bolt 34 is horizontal and perpendicular to the length direction of the crossbar 32, thereby realizing the connection and fixation between the support frame 3 and the two adjacent placement unit frames 2.

[0024] As shown in Figure 1, when the frame 1 is in the storage state, in order to store the support frame 3 which is not located within the support gap 11, the placement unit frame 2 has a storage hole 25, a storage protrusion 24 is fixedly connected to the placement unit frame 2, and a storage groove 35 is provided on the side of the crossbar 32 away from the upright 31. After the support frame 3 is positioned so that the storage protrusion 24 enters the storage groove 35, the storage hole 25 and the threaded hole on the upright 31 are aligned. At this time, the connecting bolt 34 is passed through the storage hole 25 and screwed into the upright 31, and the support frame 3 is stored in the placement unit frame 2.

[0025] The implementation principle of the prefabricated placement frame for pipe pile reinforcement cages in this application embodiment is as follows:

[0026] Based on the on-site requirements for placing the rebar cage, a certain number of continuous placement unit frames 2 are selectively chosen. After the frame body 1 is unfolded, each support frame 3 is placed in each support gap 11 and fixed, and the frame body 1 can be used directly. After use, each support frame 3 is taken out from the support gap 11 and connected to the placement unit frame 2 through the storage protrusion 24 and storage hole 25. Then each placement unit frame 2 can be folded and stored.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
