Description

Technical Field

[0001] This utility model relates to the field of steel cage support technology, and more specifically, to a movable support device inside a steel cage. Background Technology

[0002] The reinforcing cage is the main steel structure used in pouring concrete to increase the strength of the concrete. At the same time, the reinforcing cage has an internal supporting structure to enhance its stability and prevent deformation.

[0003] However, the existing internal support structure of the steel cage needs to be removed during the pouring process to avoid affecting the concrete pouring. Because it is set up inside and outside, it is difficult to operate. In addition, the support structure needs to be hoisted into the foundation pit. Construction workers need to enter the interior of the upright steel cage to carry out the removal. The removal of the steel cage is also very troublesome for construction workers because the removal of the support structure at a high position when the steel cage is upright poses certain safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a movable support device inside a steel cage, which solves the problem that when the internal support structure is removed after the steel cage is lowered, construction personnel need to enter the steel cage, making the removal very troublesome and posing safety hazards.

[0005] This utility model is achieved through the following technical solution: This utility model provides a movable support device inside a steel cage, including a steel ring, a support rod connected to the middle of the steel ring, a stop block provided at one end of the support rod, a rotating screw connected to the end of the support rod away from the stop block, a telescopic rod connected to the end of the rotating screw away from the support rod, a stop block provided at one end of the telescopic rod, and a crank provided at the other end of the telescopic rod.

[0006] Preferably, the abutment block is located on one side of one end of the support rod.

[0007] Preferably, the abutment block further includes an abutment groove, which is disposed on one side of the abutment block.

[0008] Preferably, the abutment groove is a groove provided on the outward side of the abutment block, and the groove of the abutment groove cooperates with the reinforcing bar ring.

[0009] Preferably, the rotating screw is rotatably connected to a groove at one end of the support rod.

[0010] Preferably, one end of the rotating screw is connected to the grooved thread of one end of the telescopic rod.

[0011] Preferably, the crank passes through the telescopic rod and connects to the internally fitted rotating screw, and one end of the rotating screw is provided with a cross groove, and one end of the crank is provided with a protrusion that cooperates with the cross groove at one end of the rotating screw.

[0012] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. The telescopic rod installed in the device extends and retracts, causing the support rod and the abutment block at one end of the telescopic rod to abut against the steel ring, forming a tightly abutting rod body, which applies pressure and support to the steel ring, making the steel cage more stable as a whole.

[0013] 2. The device is also equipped with a crank, which is used to control the retraction of the telescopic rod, allowing construction workers to control the telescopic rod directly from outside the steel cage, so that construction workers do not need to climb into the steel cage to dismantle the support rod.

[0018] The following is combined with Figures 1 to 3 This utility model will be described in detail.

[0019] A movable support device inside a steel cage includes a steel ring 1, a support rod 2 connected to the middle of the steel ring 1, a stop block 201 provided at one end of the support rod 2, a rotating screw 203 connected to the end of the support rod 2 away from the stop block 201, a telescopic rod 202 connected to the end of the rotating screw 203 away from the support rod 2, a stop block 201 provided at one end of the telescopic rod 202, and a crank 204 provided at one end of the telescopic rod 202.

[0020] Furthermore, the abutment block 201 is disposed on one side of one end of the support rod 2. The abutment block 201 also includes an abutment groove 2011, which is disposed on one side of the abutment block 201. The abutment groove 2011 is a groove provided on the outward side of the abutment block 201, and the groove of the abutment groove 2011 cooperates with the steel ring 1. The rotating screw 203 is rotatably connected in the groove at one end of the support rod 2. One end of the rotating screw 203 is threadedly connected to the groove at one end of the telescopic rod 202. The crank 204 passes through the telescopic rod 202 and is connected to the internally fitted rotating screw 203. One end of the rotating screw 203 is provided with a cross groove, and one end of the crank 204 is provided with a protrusion that cooperates with the cross groove at one end of the rotating screw 203.

[0021] First, the support rod 2 is placed into the rebar cage. Then, one end of the crank 204, extending from the outside of the rebar cage, is fitted into one end of the telescopic rod 202. The cross protrusion at one end of the crank 204 connects to the cross groove at one end of the rotating screw 203 in the telescopic rod 202 for a fixed connection. Then, the crank 204 is rotated directly from the outside of the rebar cage, causing the telescopic rod 202 to move due to its matching with the rotating screw 203. This causes the abutment block 201 on one side to approach the rebar ring 1 around the rebar cage. Finally, the abutment groove 2011 on one side of the abutment block 201 fits into the rebar ring 1 to form an abutment connection. One end of the support rod 2 is also supported and abutted against the rebar ring 1 through the abutment block 201. This supports the entire support rod 2 and the telescopic rod 202 against the middle of the rebar ring 1, stabilizing the rebar cage. At the same time, the telescopic support of the telescopic rod 202 can also adapt to rebar cages of different specifications.

[0022] Finally, when it is necessary to lower the steel cage, during the hoisting and lowering process, the construction personnel only need to insert the crank 204 directly into the steel cage to control the telescopic rod 202 to retract, thus completing the removal of the support rod 2, avoiding the need for personnel to climb into the steel cage for removal.

[0023] The following is a detailed implementation process of this utility model: First, the support rod 2 is placed into the reinforcing cage. Then, one end of the crank 204, extending from the outside of the reinforcing cage, is fitted into one end of the telescopic rod 202. The cross protrusion at one end of the crank 204 connects to the cross groove at one end of the rotating screw 203 in the telescopic rod 202 for a fixed connection. Then, the crank 204 is rotated directly from the outside of the reinforcing cage, causing the inner wall of the telescopic rod 202 to move due to its matching with the rotating screw 203. This causes the abutment block 201 on one side to move closer to the periphery of the reinforcing cage. The steel reinforcement ring 1 is surrounded by abutment blocks 201. Finally, the abutment groove 2011 on one side of the abutment block 201 will fit into the steel reinforcement ring 1 to form an abutment connection. One end of the support rod 2 will also be supported and abutted against the steel reinforcement ring 1 through the abutment block 201. This will support the entire support rod 2 and the telescopic rod 202 against the middle of the steel reinforcement ring 1 to stabilize the steel reinforcement cage. Finally, when the steel reinforcement cage needs to be lowered, during the hoisting and lowering process, the construction personnel only need to insert the crank 204 directly into the steel reinforcement cage to control the telescopic rod 202 to retract and complete the removal of the support rod 2, avoiding the need for personnel to climb into the steel reinforcement cage for removal.
