Description

Technical Field

[0001] The utility model specifically relates to a temporary fixing device for a steel bar cage after it is lowered. Background Art

[0002] During the construction of cast-in-place piles, in order to increase the strength and stability of the pile body, a steel cage needs to be arranged inside the pile body. By arranging the steel cage, when the pile body is subjected to external loads, the steel cage can share part of the load and work together with the pile body concrete to ensure the strength and stability of the pile body.

[0003] At present, after the steel cage is lowered into the pile hole, a temporary fixing device is required to fix the steel cage to prevent the steel cage from shifting or tilting during the subsequent pouring of concrete. However, most of the existing temporary fixing devices have simple structures, usually require multiple adjustments to fix the steel cage, and are not convenient for aligning the steel cage, reducing the practicality of the device. Therefore, in view of the above technical problems, a temporary fixing device after the steel cage is lowered is proposed. Utility Model Content

[0006] A fixing ring, coaxially arranged at the top of the pile hole;

[0007] A fixing assembly, comprising a guide column, a screw, a guide rod and a fixing seat, wherein the guide column and the screw are evenly arranged in three groups along the circumference of the fixing ring, the three groups of guide columns can be arranged on the fixing ring so as to slide radially along the fixing ring, the three groups of screws are arranged radially along the fixing ring and rotatably arranged on the fixing ring, and are respectively threadedly connected with the divergent ends of the three groups of guide columns, the guide rods are vertically arranged at the opposite ends of the three groups of guide columns, the bottom ends of the three groups of guide rods extend into the pile holes and are provided with the fixing seats, and the three groups of fixing seats are located on the peripheral side of the steel cage; and

[0008] The driving assembly is arranged on the fixing ring and connected with the three groups of the screw rods, and is used for driving the three groups of the screw rods to rotate synchronously.

[0009] The beneficial effects of the temporary fixing device after the steel cage is lowered are:

[0010] When temporarily fixing the steel cage, the three sets of screws are driven to rotate synchronously through the driving assembly. The synchronous rotation of the three sets of screws and the cooperation with the three sets of guide column threads can drive the three sets of guide columns to close and move. The closing and movement of the three sets of guide columns drive the three sets of fixing seats to close and move through the guide rods. When the closing and movement of the three sets of fixing seats collide with the sides of the steel cage, the three sets of fixing seats can clamp and fix the steel cage and make the steel cage coaxial with the pile hole. The steel cage can be fixed without multiple adjustments, and it is convenient to align the steel cage, thereby improving the practicability of the device.

[0011] In one embodiment, the driving assembly includes a bevel gear ring and a bevel gear; the bevel gear ring is coaxially rotatably arranged at the top of the fixed ring, and the coaxial bevel gears are arranged at the opposite ends of the three sets of screws, and the bevel gear ring is meshed with the three sets of bevel gears. By rotating the bevel gear ring, the bevel gear ring rotates and meshes with the three sets of bevel gears to drive the three sets of bevel gears to rotate synchronously, and the three sets of bevel gears rotate synchronously to drive the three sets of screws to rotate synchronously, which is convenient to drive the three sets of screws to rotate synchronously.

[0012] In one embodiment, a lever is vertically arranged at the top of the bevel gear ring, and a plurality of levers are evenly arranged along the circumference of the bevel gear ring. The plurality of levers can be arranged to facilitate the bevel gear ring to rotate by holding the lever, and the bevel gear ring can be driven to rotate conveniently and labor-savingly.

The fixing knobs can be rotated to allow one end of the fixing knobs to be inserted into the fixing holes. The guide rods can be slid by rotating the fixing knobs to withdraw the fixing knobs from the fixing holes. The sliding of the guide rods can adjust the depth of the guide rods inserted into the pile holes, thereby adjusting the position of the fixing seat. When the fixing seat is adjusted to a suitable position, the fixing knobs can be rotated in the opposite direction to allow the fixing knobs to be inserted into the currently matched fixing holes, thereby fixing the guide rods. This facilitates the adjustment of the position of the fixing seat according to the position of the steel cage, thereby increasing the scope of use of the device.

[0014] In one embodiment, a positioning block is provided on the periphery of the guide rod, and a positioning groove is provided on the inner wall of the guide hole, and the positioning block can be slidably arranged in the positioning groove along a vertical direction.

[0029] See also Figures 1 to 4 A temporary fixing device after the steel cage is lowered in one embodiment includes a fixing ring 10, a fixing assembly 20 and a driving assembly.

[0030] The fixing ring 10 is coaxially arranged at the top of the pile hole 1. The fixing assembly 20 includes a guide column 201, a screw 202, a guide rod 203 and a fixing seat 204. The guide column 201 and the screw 202 are evenly arranged in three groups along the circumference of the fixing ring 10. The three groups of guide columns 201 can be arranged on the fixing ring 10 to slide radially along the fixing ring 10. The three groups of screws 202 are arranged radially along the fixing ring 10 and rotatably arranged on the fixing ring 10 and are respectively threadedly connected with the divergent ends of the three groups of guide columns 201. The opposite ends of the three groups of guide columns 201 are vertically provided with guide rods 203. The bottom ends of the three groups of guide rods 203 extend into the pile hole 1 and are provided with fixing seats 204. The three groups of fixing seats 204 are located on the peripheral side of the steel cage. The driving assembly is arranged on the fixing ring 10 and connected with the three groups of screws 202 to drive the three groups of screws 202 to rotate synchronously.

[0031] Specifically, the driving assembly includes a bevel gear ring 30 and a bevel gear 301 ; the bevel gear ring 30 is coaxially and rotatably arranged at the top of the fixed ring 10 , and coaxial bevel gears 301 are arranged at opposite ends of the three sets of screws 202 , and the bevel gear ring 30 is meshed with the three sets of bevel gears 301 .

[0032] In the above embodiment, when the steel cage is temporarily fixed, the bevel gear ring 30 is rotated, and the bevel gear ring 30 rotates and engages with the three sets of bevel gears 301 to drive the three sets of bevel gears 301 to rotate synchronously. The three sets of bevel gears 301 rotate synchronously and drive the three sets of screws 202 to rotate synchronously. The three sets of screws 202 rotate synchronously and cooperate with the three sets of guide columns 201 threads to drive the three sets of guide columns 201 to close and move. The closing movement of the three sets of guide columns 201 drives the three sets of fixing seats 204 to close and move through the guide rods 203. When the three sets of fixing seats 204 close and move and contact the sides of the steel cage, the three sets of fixing seats 204 can clamp and fix the steel cage and make the steel cage coaxial with the pile hole 1. The steel cage can be fixed without multiple adjustments, and it is convenient to align the steel cage, thereby improving the practicality of the device.

[0033] Specifically in the above embodiment, a coaxial positioning ring 103 is provided at the top of the fixing ring 10, and a coaxial annular groove is provided at the bottom of the bevel gear ring 30, which is rotatably sleeved on the positioning ring 103. The cooperation between the positioning ring 103 and the annular groove can improve the rotation stability of the bevel gear ring 30.

[0041] The specific implementation of the temporary fixing device after the steel cage is lowered is as follows:

[0042] When the steel cage is temporarily fixed, the bevel gear ring 30 is rotated, and the bevel gear ring 30 rotates and meshes with the three sets of bevel gears 301 to drive the three sets of bevel gears 301 to rotate synchronously. The three sets of bevel gears 301 rotate synchronously and drive the three sets of screw rods 202 to rotate synchronously. The three sets of screw rods 202 rotate synchronously and cooperate with the three sets of guide columns 201 threads to drive the three sets of guide columns 201 to close and move. The three sets of guide columns 201 close and move and drive the three sets of fixing seats 204 to close and move through the guide rods 203. When the three sets of fixing seats 204 close and move and contact the sides of the steel cage, the three sets of fixing seats 204 can clamp and fix the steel cage and make the steel cage coaxial with the pile hole 1. The steel cage can be fixed without multiple adjustments. The reinforcement cage is fixed and it is convenient to align the reinforcement cage, which improves the practicality of the device. When it is necessary to cancel the temporary fixation of the reinforcement cage, the bevel gear ring 30 is rotated in the opposite direction, and the bevel gear ring 30 rotates in the opposite direction to engage with the three sets of bevel gears 301 to drive the three sets of bevel gears 301 to rotate in the opposite direction synchronously, thereby driving the three sets of screws 202 to rotate in the opposite direction synchronously. The three sets of screws 202 rotate in the opposite direction synchronously and cooperate with the three sets of guide columns 201 threads to drive the three sets of guide columns 201 to open and move. The opening and movement of the three sets of guide columns 201 drives the three sets of fixing seats 204 to open and move through the guide rods 203, thereby separating the three sets of fixing seats 204 from the reinforcement cage, and conveniently canceling the temporary fixation of the reinforcement cage.
