Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a positioning device for pre-buried anchor bolts of steel structure columns. Background Art

[0002] Anchor bolts are used to fix equipment without strong vibration and impact. The accuracy of pre-embedded anchor bolts in steel structure foundation is a very important factor affecting the quality of steel structure installation.

[0003] After the concrete is poured at the bottom of the anchor bolt, the position of the anchor bolt is fixed when the concrete solidifies, and the angle of the anchor bolt cannot be adjusted. Therefore, once the angle of the anchor bolt deviates, the angle of the anchor bolt cannot be adjusted. The only way is to use tools to bend the anchor bolt above the concrete to a specified angle, which is inconvenient and may cause the anchor bolt to break accidentally.

[0004] Therefore, it is necessary to improve the traditional anchor bolt pre-embedded positioning device to avoid the above-mentioned problems. Utility Model Content

[0007] A positioning device for embedded anchor bolts of steel structure columns comprises a base and an anchor bolt body, wherein the base is connected to a pressure plate 1 via an adjusting piece, the pressure plate 1 is provided with an arc groove, the pressure plate 1 is fixedly connected to a vertical rod, and is rotatably connected to a rotating rod, the vertical rod is slidably connected to a sliding hole provided on a pressure plate 2, the rotating rod is threadedly connected to a connecting hole provided on the pressure plate 2, the pressure plate 2 is provided with an opening, and a ball head is fixedly connected to the bottom of the anchor bolt body.

[0008] Preferably, the adjusting member comprises a fixing column fixedly connected to the base, a screw rod is fixedly connected to the fixing column, a bottom of the pressure plate 1 is fixedly connected to a bottom column, and a screw hole is provided on the bottom column which is threadedly connected to the screw rod.

[0009] Preferably, a reinforcement ring 1 is fixedly connected to the outer wall of the fixing column, and a reinforcement ring 2 is fixedly connected to the bottom of the pressure plate 1.

[0010] Preferably, an elastic rubber gasket protrudes from the portion of the arc-shaped groove that contacts the ball head.

[0011] Preferably, an end block is fixedly connected to the end of the rotating rod.

[0012] Preferably, the anchor bolt body passes through the opening, and a rubber gasket protrudes from the bottom of the second pressure plate at the part in contact with the ball head.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. The present application is embedded in the concrete through the base and the bottom of the pressure plate 1. The staff can also rotate the anchor bolt body to change the angle of the anchor bolt body. After adjusting to the appropriate angle, the rotating rod can be rotated to cause the pressure plate 2 to cooperate with the pressure plate 1 to clamp the ball head. At this time, the anchor bolt body can maintain the adjusted angle to complete the positioning operation, which is more convenient to operate.

[0015] 2. The present application can increase the connection strength between the base and the pressure plate 1 and the concrete, and increase the contact area between the base and the pressure plate 1 and the concrete through the cooperation of the reinforcement ring 1 and the reinforcement ring 2, so that the positioning device can be fixed more firmly in the concrete.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3, the utility model provides a technical solution:

[0023] A positioning device for pre-embedded anchor bolts of steel structure columns includes a base 1 and an anchor bolt body 14. The base 1 is connected to a pressing plate 1 8 through an adjusting member. The pressing plate 1 8 is provided with an arc groove 9. The pressing plate 1 8 is fixedly connected to a vertical rod 10 and rotatably connected to a rotating rod 11. The end of the rotating rod 11 is fixedly connected to an end block 12. The vertical rod 10 is slidably connected to a sliding hole 17 provided on a pressing plate 2 15. The rotating rod 11 is threadedly connected to a connecting hole 18 provided on the pressing plate 2 15. The pressing plate 2 15 is provided with an opening 16. The bottom of the anchor bolt body 14 is fixedly connected to a ball head 13. A reinforcing ring 1 3 is fixedly connected to the outer wall of the fixed column 2, and a reinforcing ring 2 6 is fixedly connected to the bottom of the pressing plate 1 8. The reinforcing ring 1 3 cooperates with the reinforcing ring 2 6 to increase the contact area between the base 1 and the pressing plate 1 8 and concrete, so that the connection strength between the base 1 and the pressing plate 2 15 and concrete is increased.

[0024] Specifically, Figure 1 As shown, the adjusting member includes a fixing column 2 fixedly connected to the base 1, a screw rod 4 is fixedly connected to the fixing column 2, a bottom of the pressure plate 8 is fixedly connected to a bottom column 5, and a screw hole 7 is provided on the bottom column 5 to be connected to the screw rod 4 through a thread.

[0025] Specifically, Figure 2 As shown, an elastic rubber gasket protrudes from the portion where the arc groove 9 contacts the ball head 13. The anchor bolt body 14 passes through the opening 16, and a rubber gasket protrudes from the portion where the bottom of the second pressing plate 15 contacts the ball head 13. Therefore, the friction force is relatively large when the arc groove 9 and the second pressing plate 15 contact the ball head 13, so that the ball head 13 can maintain a stable angle after adjustment.

[0026] In summary, the base 1 provided in this embodiment is pre-buried in concrete, and then the screw rod 4 and the screw hole 7 can be connected by threads, and the height of the anchor bolt body 14 can be adjusted. Then the anchor bolt body 14 can be rotated until the anchor bolt body 14 is adjusted to a specified angle. The end block 12 is rotated to rotate the rotating rod 11, and the pressure plate 2 15 moves downward. The pressure plate 2 15 cooperates with the pressure plate 1 8 to clamp the ball head 13, and the anchor bolt 14 at this time maintains the adjusted angle. Finally, concrete can be poured on the positioning device until the pressure plate 2 15 is buried in the concrete, and the top of the anchor bolt body 14 is exposed.

[0027] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
