Description

Technical Field

[0001] This utility model relates to the field of steel cage fixing, specifically a steel cage fixing device for cast-in-place piles. Background Technology

[0002] A cast-in-place pile is a deep foundation formed by drilling holes in the ground, inserting a reinforcing cage, and finally pouring concrete. The reinforcing cage is a cylindrical skeleton structure formed by welding or binding reinforcing bars together according to design requirements. Simply put, the reinforcing cage is the "skeleton" of the cast-in-place pile. It provides the pile with tensile, shear, and bending strength, enabling the concrete (which has good compressive strength) to jointly bear the various loads transmitted from the superstructure.

[0003] The existing technology is as follows: Figure 4 As shown, when the reinforcing cage is placed into the bored pile hole, it is supported by a horizontal steel pipe to prevent the hole from sinking. Although the existing technology can facilitate the support of the reinforcing cage, it cannot control the centering of the reinforcing cage, resulting in uneven thickness of the outer concrete layer after the concrete is poured. Therefore, a new fixing device for the reinforcing cage of the bored pile is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for the reinforcing cage of a cast-in-place pile, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixing device for a cast-in-place pile reinforcement cage includes a support beam. Two sliding seats are slidably connected to the outer side of the support beam. The sliding seats are symmetrically provided with claws on one side outward. The claws are locked onto the outer side of the annular reinforcement of the reinforcement cage supported by the support beam. The claws are fixedly connected to an installation frame. Guide rods are symmetrically fixedly connected to both sides of the installation frame. The guide rods slide through the sliding seats. A first threaded handle is threadedly connected to the middle of the sliding seat. One end of the first threaded handle is rotatably installed with the installation frame. A stop is fixedly connected to the bottom surface of the sliding seat. The stop abuts against the inner wall of the cast-in-place pile hole.

[0007] As a further embodiment of this utility model: a cone is fixedly connected to one side of the abutment in the direction of the end of the beam.

[0008] As a further improvement of this utility model: the two sides of the supporting beam are symmetrically provided with protruding ribs, and the sliding seat is limited by the rotation of the protruding ribs.

[0009] As a further embodiment of this utility model: the two ends of the supporting beam are connected to the supporting seats, the supporting seats are slidably penetrated by the supporting beam, the supporting seats and the supporting beam are fixedly installed by fixing bolts, the supporting seats and the supporting beam are provided with round holes for the fixing bolts to pass through, and the bottom end of the fixing bolt is threaded with a nut.

[0010] As a further improvement of this utility model: the two sides of the support base are symmetrically threaded with second threaded handles, and the bottom end of the second threaded handles is fixedly connected with pads.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model supports the reinforcing cage in the grouting pile hole by means of a supporting beam. By rotating the first threaded handle, the chuck is driven to approach the corresponding annular reinforcing bar of the reinforcing cage under the guidance of the guide rod, so that the chuck is locked on the outside of the annular reinforcing bar. At the same time, the sliding seat is pushed outward in the opposite direction, so that the abutment is pressed against the inner wall of the grouting pile hole. With the help of a measuring tape, the reinforcing cage is centered in the grouting pile hole.

[0013] 2. After the abutment of this utility model is placed against the inner wall of the grouting pile hole, it can be inserted into the ground by inserting a cone to form an upper and lower limit. At the same time, the claws limit the upper and lower ring bars of the steel cage, thereby preventing the steel cage from floating during the grouting construction.

[0014] 3. This utility model allows for adjustment of the support height of the support base by rotating the second threaded handle in conjunction with the pad, thereby controlling the setting height of the beam and facilitating the control of the support elevation of the reinforcing cage.

[0015] 4. The support seat of this utility model is assembled with the support beam by fixing bolts, and the sliding seat slides on the support beam, so that both the support seat and the sliding seat can be disassembled. When the support beam passes through the steel cage, the support seat and the sliding seat are disassembled to avoid interference and prevent the support beam from being inserted into the steel cage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 In this embodiment of the utility model, a fixing device for a cast-in-place pile reinforcement cage includes a support beam 1. Two sliding seats 2 are slidably connected to the outer side of the support beam 1. The sliding seats 2 are symmetrically provided with claws 3 on one side. The claws 3 are locked on the outer side of the annular reinforcement cage supported by the support beam 1. The claws 3 are fixedly connected to the mounting frame 4. Guide rods 5 are symmetrically fixedly connected to both sides of the mounting frame 4. The guide rods 5 slide through the sliding seats 2. A first threaded handle 6 is threadedly connected to the middle of the sliding seat 2. One end of the first threaded handle 6 is rotatably installed with the mounting frame 4. A stop 7 is fixedly connected to the bottom surface of the sliding seat 2. The stop 7 abuts against the inner wall of the cast-in-place pile hole.

[0023] The reinforcing cage is supported in the grouting pile hole by the supporting beam 1. By rotating the first threaded handle 6, the chuck 3 is driven to approach the corresponding annular reinforcing bar of the reinforcing cage under the guidance of the guide rod 5, so that the chuck 3 is locked on the outside of the annular reinforcing bar. At the same time, the sliding seat 2 is pushed outward in the opposite direction, so that the abutment 7 is pressed against the inner wall of the grouting pile hole. With the help of the measuring tape, the reinforcing cage is centered in the grouting pile hole.

[0024] A cone 8 is fixedly connected to one side of the seat 7 towards the end of the beam 1.

[0025] After the seat 7 is pressed against the inner wall of the cast-in-place pile hole, the cone 8 can be inserted into the ground to form upper and lower limits. At the same time, the claw 3 limits the upper and lower ring bars of the steel cage, thereby preventing the steel cage from floating during the grouting construction.

[0026] The two sides of the supporting beam 1 are symmetrically provided with protruding ribs 9, and the sliding seat 2 is limited by the rotation of the protruding ribs 9.

[0027] Support seats 10 are connected to both ends of the beam 1. The support seats 10 are slidably penetrated by the beam 1. The support seats 10 and the beam 1 are fixedly installed by fixing bolts 11. The support seats 10 and the beam 1 are provided with round holes for the fixing bolts 11 to pass through. The bottom end of the fixing bolts 11 is threaded with a nut. The sliding seat 2 and the support seat 10 are both provided with sliding cavities that are compatible with the beam 1 and the rib 9.

[0028] The support base 10 has symmetrical threaded connections on both sides to a second threaded handle 12, and a pad 13 is fixedly connected to the bottom end of the second threaded handle 12.

[0029] By rotating the second threaded handle 12, the support height of the support base 10 can be adjusted in conjunction with the pad 13, thereby controlling the setting height of the beam 1 and facilitating the control of the support elevation of the reinforcing cage.

[0030] The support seat 10 is assembled with the support beam 1 by fixing bolts 11, and the sliding seat 2 slides on the support beam 1, so that both the support seat 10 and the sliding seat 2 can be disassembled. When the support beam 1 passes through the steel cage, the support seat 10 and the sliding seat 2 are disassembled to avoid interference and prevent the support beam 1 from being inserted into the steel cage.

[0031] The working principle of this utility model is as follows:

[0032] In use, firstly, the supporting beam 1 is inserted through the suspended reinforcing cage. Sliding seats 2 and support seats 10 are installed at both ends of the supporting beam 1. The support seats 10 are locked with fixing bolts 11. By rotating the second threaded handle 12 and cooperating with the pad 13, the support height of the support seats 10 is adjusted, thereby controlling the setting height of the supporting beam 1 and thus controlling the support elevation of the reinforcing cage. By rotating the first threaded handle 6, under the guidance of the guide rod 5, the chuck 3 is driven to approach the corresponding annular reinforcing bar of the reinforcing cage, so that the chuck 3 is locked on the outside of the annular reinforcing bar. At the same time, the sliding seat 2 is pushed outward in the opposite direction, so that the abutment 7 is pressed against the inner wall of the grouting pile hole. With the help of a measuring tape, the reinforcing cage is controlled to be placed in the center of the grouting pile hole. After the abutment 7 is pressed against the inner wall of the grouting pile hole, the insert cone 8 can be inserted into the ground to form upper and lower limits. At the same time, the chuck 3 limits the upper and lower annular reinforcing bars of the reinforcing cage, thereby preventing the reinforcing cage from floating during the grouting construction.
