Rebar for reinforced concrete refers to straight bars or coiled steel used for reinforced concrete reinforcement. Its appearance is divided into plain round steel bars and deformed steel bars, and the delivery state is straight bars and coiled steel bars.

[0003] The patent with the patent authorization announcement number CN116498088A discloses a steel bar positioning structure. When assembling the steel bar cage, the staff can adjust the specifications of the positioning main plate and the movable main plate according to the size of the steel bar cage to be built. After the adjustment, the steel bars are evenly placed in a ring between the positioning main plate and the movable main plate, and the magnetic suction mechanism on the positioning main plate and the movable main plate is turned on to fix the steel bars. Then the staff welds and reinforces the overall contour to achieve the purpose of building the steel bar cage. However, the steel bar positioning structure provided by the patent still has shortcomings in actual use. After the steel bars are positioned and installed, the outer periphery of the steel bars needs to be connected with stirrups to form a steel bar cage. The stirrups are connected by manual picking and lifting by the staff during installation, which greatly increases the workload and is time-consuming and laborious.

[0004] Therefore, it is necessary to provide a steel bar positioning and installation device that can realize automatic lifting and lowering of stirrups. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Embodiment 1: A construction steel bar positioning and installation device, see Figure 1-Figure 3As shown, it includes a base plate 1, a first screw rod 3, a nut 4, a clamping block 5, a second screw rod 6 and a clamping plate 7. Two first screw rods 3 are threadedly arranged on both sides of the two base plates 1. The nuts 4 are threadedly connected to the first screw rods 3. Six clamping blocks 5 for clamping and fixing the steel bars 2 are horizontally slidably arranged on the base plate 1. The clamping blocks 5 are horizontally slidably arranged with clamping plates 7 for clamping the steel bars 2. The clamping blocks 5 are threadedly arranged with second screw rods 6. The second screw rods 6 are rotatably connected to the clamping plates 7. The clamping plates 7 and the clamping blocks 5 are clamped together. The invention holds and fixes the steel bars 2, and also includes a first motor 8, a second screw 6, a guide rod 10 and a lifting plate 11. A base plate 1 is installed with the first motor 8 by means of bolt connection. The output shaft of the first motor 8 faces upward and is fixedly connected with the third screw 9 by means of a coupling. A guide rod 10 is installed on the other base plate 1 by means of relief. The lifting plate 11 is threadedly connected to the third screw 9. The lifting plate 11 is slidably arranged on the guide rod 10. The two lifting plates 11 are fixedly connected by means of the first screw 3 and the nut 4.

[0024] When the steel bar cage 2 needs to be assembled, the two bottom plates 1 are connected by the combination of the first screw 3 and the nut 4, and the two lifting plates 11 are connected by the combination of the first screw 3 and the nut 4. After the steel bar 2 is placed in the slot of the bottom plate 1, the clamping block 5 is moved to a suitable position, and the second screw 6 on the clamping block 5 is rotated to make the clamping plate 7 approach the clamping block 5 to clamp the steel bar 2; then the stirrup 201 is placed on the two lifting plates 11, and the third screw 9 is driven by the output shaft of the first motor 8. By rotating, the third screw 9 drives the lifting plate 11 to slide along the guide rod 10 to achieve up and down lifting, so that the stirrup 201 is lifted and lowered to the required installation position, and then the workers can tie and fix the stirrup 201 with the steel bar 2; after the steel bar 2 cage is installed, the steel bar 2 is clamped by rotating the second screw 6, and the clamping block 5 is slid away from the steel bar 2, and then the first screw 3 and the nut 4 on the bottom plate 1 and the lifting plate 11 are rotated and disassembled, and finally the bottom plate 1 and the lifting plate 11 can be taken out from both sides.

[0025] Example 2: Based on Example 1, refer to Figure 4 As shown, it also includes two base plates 1 on which mounting plates 12 are installed by bolt connection, two screws 13 for reinforcing the connection with the ground are threadedly arranged on the mounting plate 12, and a pulley group 1301 for transmitting power is commonly connected to the two screws 13, a mounting frame 14 is installed by bolt connection on the base plate 1, a lifting ring 15 is slidably arranged on the mounting frame 14, a second motor 16 is installed on the lifting ring 15 by bolt connection, the lifting ring 15 drives the second motor 16 to slide up and down along the mounting frame 14, and the output shaft of the second motor 16 is fixedly connected to the screws 13 through a coupling.

[0026] When the base plate 1 is assembled, the screw 13 is driven to rotate by starting the motor, and the screw 13 at the other end is driven to rotate synchronously through the pulley set 1301, so that the two screws 13 are drilled into the ground. At this time, the motor slides downward along the mounting frame 14 through the lifting ring 15, and the base plate 1 is fixed to the ground through the screw 13 to prevent the bottom from moving.

[0027] See also Figure 5 and Figure 6 As shown, it also includes a connecting plate 17 installed on the top of the clamping block 5 by bolt connection, and a telescopic plate 18 is slidably arranged in the connecting plate 17, and the telescopic plate 18 slides up and down in the connecting plate 17, and two symmetrically arranged clamping rods 19 are horizontally slidably arranged on both sides of the lower part of the telescopic plate 18, and a first elastic member 20 is wound around the clamping rod 19. A plurality of clamping grooves 21 corresponding to the clamping rod 19 are arranged in the connecting plate 17, and the first elastic member 20 is used to push the clamping rod 19 to slide and reset and engage with the clamping groove 21, and a movable plate 22 is horizontally slidably arranged on the upper part of the telescopic plate 18, and two symmetrical stoppers 23 for limiting the position of the steel bar 2 are slidably arranged at one end of the movable plate 22, and a second elastic member 24 is wound around the stopper 23, and the second elastic member 24 pushes the two stoppers 23 to slide close to reset and limit the steel bar 2.

[0028] After the steel bar 2 is placed, the telescopic plate 18 is pulled to lift and lower in the connecting plate 17 to adjust the clamping position, and the two clamping rods 19 are pushed to slide to the side away from each other by the first elastic member 20, so that the clamping rods 19 and the connecting plate 17 are clamped and fixed, and then the movable plate 22 is pulled to slide to the side close to the steel bar 2. During the movement, the steel bar 2 pushes the two blocks 23 to both sides. At this time, the second elastic member 24 is compressed and deformed by force. After the steel bar 2 completely passes through the block 23, the second elastic member 24 pushes the block 23 to slide and reset, and the steel bar 2 is limited by the two blocks 23, so that the steel bar 2 cannot move.

[0029] See also Figure 4 and Figure 6 As shown, a wear-proof sleeve 25 is installed on one side of the movable plate 22 close to the stopper 23 by bonding; a protective sleeve 26 is sleeved on the pulley of the movable plate 22; and a protective cover 27 is sleeved on the outside of the pulley assembly 1301.

[0030] The anti-wear sleeve 25 can reduce the friction between the steel bar 2 and the movable plate 22; the protective sleeve 26 can increase the friction between the hand and the movable plate 22, avoiding hand slippage when pulling the movable plate 22, and making people feel more comfortable; the protective cover 27 can protect the normal operation of the pulley group 1301 and prevent it from being damaged.
