Description

Technical Field

[0001] This invention belongs to the field of building engineering, and in particular relates to an auxiliary device for assembling stirrups in beam and column reinforcement. Background Technology

[0002] A beam is a structural member supported by supports and subjected primarily to lateral and shear forces, with bending as its main deformation. Beams bear the entire weight of the building's superstructure and roof, making them the most crucial part of the superstructure. The orientation of most beams aligns with the building's cross-section. When the beam's cross-section has a high reinforcement ratio, installing stirrups becomes more difficult. Conventionally, stirrups are placed in the middle of the beam and then manually hammered to both ends; however, this method is time-consuming and labor-intensive. Therefore, a U-shaped + I-shaped auxiliary assembly structure can be formed using angle steel. Connections are made with bolts, and internal clamping blocks compress some space, facilitating the movement of the stirrups to the edges. Summary of the Invention

[0003] The purpose of this invention is to provide an assembly auxiliary device that facilitates the installation of stirrups on reinforced concrete.

[0008] Furthermore, the first transmission unit includes a second transmission bevel gear, a transmission rod, and a first transmission gear. The second transmission bevel gear and the first transmission gear are fixedly provided at both ends of the transmission rod. The transmission rod is rotatably provided in the second cavity, and the second transmission bevel gear meshes with the first transmission bevel gear.

[0009] Furthermore, the second transmission unit includes a second transmission tooth, a chain, and a toothed disc; two toothed discs are rotatably provided in the third cavity and the first cavity along the length direction, respectively, and the chain is engaged on the two toothed discs of the same second transmission unit. The second transmission tooth is fixedly provided on the toothed disc near the second cavity, and the second transmission tooth engages with the first transmission tooth, and the chain engages with the push frame.

[0010] Furthermore, the push frame includes a scissor frame and a U-shaped frame. One end of one side of the first frame is provided with a through groove that connects to the first cavity. One end of the same side of the third frame is provided with a through groove that connects to the third cavity. A first sliding seat is slidably provided in both through grooves. The bottom of the first sliding seat is provided with teeth that mesh with the chain.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0016] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0017] like Figure 1-6 As shown, the stirrup assembly auxiliary device for beam and column reinforcement includes a frame and a pusher. The frame includes a first frame 1, a second frame 2, a third frame 3, and a fourth frame 4 connected end to end. The inner sides of the first frame 1 and the second frame 2 are provided with compression structures 5 for compressing the reinforcement. The first frame 1 and the third frame 3 are connected to a pusher for pushing. The first frame 1, the second frame 2, and the third frame 3 are provided with transmission components 9, which are connected to the pusher. Manually rotating the first handle 502 pushes the compression structure 5 inward, causing the reinforcement to retract inward, thereby loosening the stirrup and the reinforcement. This facilitates the pusher to push the stirrup to the appropriate position by rotating the second handle 908.

[0018] like Figure 4-5 As shown, a first cavity 103 is provided inside the first frame 1 along its length direction, and a first limiting groove 104 is provided inside the first frame 1 along its length direction to communicate with the first cavity 103. A compression structure 5 is provided inside the first cavity 103 and the first limiting groove 104. A second cavity 202 is provided inside the second frame 2 along its length direction, and a second limiting groove 203 is provided inside the second frame 2 along its length direction to communicate with the second cavity 202. Another compression structure 5 is provided inside the second cavity 202 and the second limiting groove 203. The compression structure 5 includes a first rotating tooth 501, a first throttle 502, a first transmission tooth 503, a screw 504, a strip slider 505, and a clamping block 506. A first rotating tooth 501 is rotatably provided at the bottom of the first cavity 103 and the second cavity 202, respectively. The first rotating tooth 501 abuts against the upper and lower ends of the first cavity 103 and the second cavity 202. Simultaneously, the first cavity 103 and the second cavity 202 are provided with matching limiting grooves to prevent the first rotating tooth 501 from lateral jumping. A strip slider 505 is slidably provided within the first limiting groove 104 and the second limiting groove 203, respectively. The first limiting groove 104 and the second limiting groove 203 are stepped grooves, and the strip slider 505 is a stepped block (e.g., Figure 4-5(As shown in the diagram) To prevent the strip slider 505 from sliding out of the first and second limiting grooves, a first throttle 502 is respectively provided through the outer walls of the first frame 1 and the second frame 2; a first transmission tooth 503 is fixedly provided at the bottom of the first throttle 502, a screw 504 is fixedly provided at the top of the strip slider 505, and a clamping block 506 is fixedly provided at the bottom of the strip slider 505; a first rotating tooth 501 meshes with the first transmission tooth 503, and a threaded through hole 5011 is provided on the first rotating tooth 501, which is threadedly connected to the screw 504. When the first throttle 502 is rotated, it drives the first transmission tooth 503 to drive, thereby driving the first rotating tooth 501 to rotate. When the first rotating tooth 501 rotates, it drives the screw 504 (strip slider 505 and clamping block 506) to move up and down, thereby compressing the internal space formed by the frame body, and thus achieving inward compression of the reinforcing bars. The inner side of the clamping blocks 506 (third frame 3, fourth frame 4) is made of rubber to increase friction with the reinforcing bars and prevent slippage. The number of teeth of the first transmission gear 503 is less than the number of teeth of the first rotating gear 501 to increase the output torque and achieve the purpose of saving effort. The input and output torque ratio can be adjusted by adjusting the number of teeth. Since only a slight looseness between the stirrups and the reinforcing bars is required, only a small gap is needed between the two vertical clamping blocks 506 (the gap is less than half the diameter of a reinforcing bar). The frame as a whole and the reinforcing bars as a whole can be regarded as a clearance fit. Each clamping block 506 can contact the outermost reinforcing bars at both ends, which can ensure that all the reinforcing bars on the corresponding side are compressed.

[0019] like Figure 3 As shown, the transmission component 9 includes a second throttle 908, a transmission bevel gear 907, a first transmission unit, and a second transmission unit. The second throttle 908 is installed through the outer wall of the second frame 2. The portion of the second throttle 908 located within the second cavity 202 is fixedly connected to the transmission bevel gear 907. The second throttle 908 is positioned near the middle of the second frame 2. Two first transmission units are symmetrically located at both ends of the transmission bevel gear 907 along the length of the second frame 2. The third frame 3 has a third cavity, and a second transmission unit is provided in both the third cavity and the first cavity 103. The transmission bevel gear 907 engages with two first transmission units, the first transmission units engage with the second transmission unit, and the second transmission unit engages with the push frame. When the transmission bevel gear 907 rotates, it drives the first transmission unit to rotate, which in turn drives the second transmission unit to rotate, thereby causing the push frame to extend and retract. To ensure synchronous extension and retraction of the two scissor lifts 6 and prevent the stirrups from jamming, both sets of first and second transmission units are engaged on the same transmission bevel gear 907.

[0020] More specifically, the first transmission unit includes a second transmission bevel gear 906, a transmission rod 905, and a first transmission gear 903. The transmission rod 905 has the second transmission bevel gear 906 and the first transmission gear 903 fixedly mounted at both ends. The transmission rod 905 is rotatably mounted within the second cavity 202, and is arranged along the length of the second frame 2. The second transmission bevel gear 906 meshes with the first transmission bevel gear 907. The second transmission unit includes a second transmission gear 904, a chain 902, and a chain 901. Two chain 901s are rotatably mounted along the length of the third cavity and the first cavity 103, respectively. A chain 902 meshes with the two chain 901s of the same second transmission unit. The chain 904 is fixedly mounted on the chain 901 closest to the second cavity 202, meshing with the first transmission gear 903. The chain 902 meshes with the push frame. The arrangement of each gear is as follows: Figure 3 As shown, in order to ensure that the two scissor lifts 6 can extend and retract synchronously, it is necessary to ensure that the two chains 902 can rotate in the same direction. Therefore, a transmission gear (not shown in the figure) is added between one set of transmission gears 904 and 903. The number of teeth of the transmission gear should be the same as that of transmission gear 903.

[0021] In addition, the push frame includes a scissor lift 6 and a U-shaped frame 8. One end of one side of the first frame 1 is provided with a through groove 102 that connects to the first cavity 103. One end of the same side of the third frame 3 is provided with a through groove 102 that connects to the third cavity. A first sliding seat 701 is slidably provided in the two through grooves 102. The bottom of the first sliding seat 701 is provided with a tooth 7011 that meshes with a chain 902. The other end of the side of the first frame 1 and the third frame 3 with the through groove 102 is provided with a first fixed seat 702. The two ends of the bottom of the scissor lift 6 are respectively hinged to the first fixed seat 702 and the first sliding seat 701. The two ends of the top of the two scissor lifts 6 are respectively hinged to the second fixed seat 703 and the second sliding seat 704 provided at the bottom of the U-shaped frame 8. To ensure the stability of the connection between the chain 902 and the toothed part 7011 and prevent them from falling off, a limiting baffle along the length of the first frame 1 can be provided on the side wall of the first cavity 103 near the through groove 102. The limiting baffle is parallel to the through groove 102, and the chain 902 is located between the limiting baffle and the through groove 102. A roller 801 is provided on the inner side of the U-shaped frame 8. The roller 801 ensures that there is sliding friction between the U-shaped frame 8 and the reinforcing bars, which facilitates the U-shaped frame 8 to push the stirrups.

[0022] like Figure 3As shown, the scissor lift 6 includes several scissor lift groups connected in sequence. Each scissor lift group includes a first push rod 601 and a second push rod 602 hinged at their centers. Both ends of the first push rod 601 are hinged to one end of an adjacent second push rod 602, and both ends of the second push rod 602 are hinged to one end of an adjacent first push rod 601. At the head end of the scissor lift 6, the first push rod 601 is hinged to a first sliding seat 701, and the second push rod 602 at the head end of the scissor lift 6 is hinged to a first fixed seat 702. At the tail end of the scissor lift 6, the first push rod 601 is hinged to a second fixed seat 703, and the second push rod 602 at the tail end of the scissor lift 6 is hinged to a second sliding seat 704. It should be noted that, to ensure the stability of the scissor lift 6, the first sliding seat 701 and the second sliding seat 704 of each group should be located at the same end (e.g., ...). Figure 3 As shown in the image).

[0023] like Figure 6 As shown, the first frame 1, the second frame 2 and the third frame 3 are vertically connected. One end of the fourth frame 4 is hinged to the third frame 3, and the other end is provided with a connecting screw 401. The end of the first frame 1 near the fourth frame 4 is provided with a limiting groove 105 that is adapted to the connecting screw 401. The bolt is threaded to press the screw 401 onto the first frame 1 so as to fix the first frame 1 and the fourth frame 4 relative to each other.

[0024] It should be noted that, in order to push the stirrups on both sides, the scissor lift 6 and the U-shaped frame 8 can be symmetrically arranged on both sides of the frame body. At the same time, corresponding transmission components 9 need to be set, which can be mirrored in the arrangement of this embodiment.

[0025] Working principle: Rotate the fourth frame 4 away from the first frame 1, place the frame body and pusher on the reinforcement, rotate the fourth frame 4 so that the screw 401 is in the groove 105, tighten the bolts to fix the first frame 1 and the fourth frame 4 relatively. Rotate the first handle 502 on the first frame 1 and the second frame 2 so that the clamping block 506 compresses the reinforcement inward until the reinforcement and the stirrup are slightly loose. Then rotate the second handle 908 to push the scissor frame 6 to extend through the first transmission unit and the second transmission unit, so as to push the U-shaped frame 8 to the stirrup. When it is pushed to the appropriate position, rotate the second handle 908 in the opposite direction to retract it. Then remove the bolts and remove the frame body.

Any modifications, alterations, substitutions, or variations made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention shall fall within the protection scope defined by the claims of the present invention.
