Description

Technical Field

[0001] This utility model relates to the technical field of construction positioning devices for concrete components, specifically a construction positioning device for prefabricated concrete components. Background Technology

[0002] Concrete components generally refer to the basic components of concrete structures. Precast components include precast beams, columns, and wall panels. Precast columns require positioning devices for use and storage to fix and limit their position. In existing technology, precast columns are usually fixed by bolts and clamps. However, due to the special shape of precast columns, conventional clamps can easily cause excessive force and damage to the exterior of the precast columns when fixing them. At the same time, when multiple clamps are used to position the precast columns, the fixing points of the clamps are different, which can cause the precast columns to become skewed during use, reducing their effectiveness. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated concrete component construction positioning device to solve the technical problems of excessive force applied when fixing prefabricated columns with the aforementioned clamps, which can easily damage the exterior of the prefabricated columns. Furthermore, when multiple clamps are used to position the prefabricated columns, the different fixing points of the clamps can lead to the prefabricated columns becoming skewed during use, thus reducing the effectiveness of the prefabricated columns during use.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated concrete component construction positioning device, comprising: a bracket, wherein a positioning mechanism is assembled in the inner cavity of the bracket, the positioning mechanism includes a threaded rod and a bent arm, a nut is externally threaded onto the threaded rod, a T-shaped frame is externally connected to the threaded rod, trapezoidal blocks are connected to both the left and right sides of the T-shaped frame, and the bent arm is rotatably disposed on both sides of the inner cavity of the bracket.

[0007] The bottom of the threaded rod is equipped with a driving mechanism, which includes a square arm. A second spring is connected between the square arm and the threaded rod. Horizontal arms are connected to both sides of the second spring. Locking rods are evenly distributed on the top of the inner cavity of the bracket.

[0008] Preferably, the top left and right sides of the bracket are provided with transverse grooves, and the front and rear ends of the inner cavity of the transverse grooves are connected to the curved arm through bearings with seats, so that the transverse grooves can facilitate the rotation of the curved arm.

[0009] Preferably, the top of the T-shaped frame is rotatably connected to the outside of the curved arm with rollers, and the outside of the rollers is fitted with rubber sleeves, which improves the positioning effect of the precast column.

[0011] Preferably, vertical grooves are provided on both the left and right sides of the outer side of the threaded rod, and the vertical grooves are slidably connected to the horizontal arm, which facilitates the horizontal arm to slide up and down.

[0012] Preferably, a torsion wheel is connected to the bottom of the square arm, and the torsion wheel has anti-slip texture on its outer surface. The torsion wheel facilitates the movement of the square arm and the rotation of the threaded rod.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a prefabricated concrete component construction positioning device, which has the following beneficial effects:

[0015] This prefabricated concrete component construction positioning device, through the addition of threaded rods, nuts, T-shaped frames, trapezoidal blocks, and bent arms, can quickly fix the position of precast columns and locate the center position of the precast columns. This ensures that the position of the precast columns is fixed when multiple devices are used to fix them, preventing skewness during fixing. At the same time, through the addition of square arms, second springs, cross arms, and locking rods, the positioning mechanism automatically locks itself after the positioning mechanism has fixed the precast columns, preventing the positioning mechanism from being driven by environmental factors and causing positioning failure of the precast columns.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A prefabricated concrete component construction positioning device includes: a support 1, a positioning mechanism 2 installed in the inner cavity of the support 1, the positioning mechanism 2 including a threaded rod 21 and a bent arm 24, a nut 22 externally threaded to the threaded rod 21, and a T-shaped frame 23 externally connected to the threaded rod 21, the T-shaped frame 23 being inserted into the bottom of the support 1 and being able to slide up and down on the bottom of the support 1, trapezoidal blocks 25 being connected to both sides of the T-shaped frame 23, and the bent arm 24 being rotatably set on both sides of the inner cavity of the support 1.

[0023] The bracket 1 can support the positioning mechanism 2. The threaded rod 21 is connected to the bracket 1 through a bearing with a seat. The threaded rod 21 can drive the nut 22 to move up and down by rotating. The T-shaped frame 23 can be driven by the nut 22 and guide the nut 22 to prevent it from rotating during up and down movement. The trapezoidal block 25 can drive the bent arm 24 to move. The bent arm 24 can fix the precast column.

[0024] Please see Figure 3 and Figure 4 The bottom of the threaded rod 21 is equipped with a drive mechanism 3. The drive mechanism 3 includes a square arm 31. A second spring 32 is connected between the square arm 31 and the threaded rod 21. A cross arm 33 is connected to both sides of the second spring 32. The top of the inner cavity of the bracket 1 is evenly distributed with locking rods 34.

[0025] The square arm 31 can drive the threaded rod 21 to move. The second spring 32 can pull the square arm 31 to return to its original position when it moves. The horizontal arm 33 can cooperate with the locking rod 34 to limit the square arm 31. The bottom of the locking rod 34 has a short groove to facilitate the horizontal arm 33 to be inserted.

[0026] The top left and right sides of the bracket 1 are provided with horizontal grooves 11. The front and rear ends of the inner cavity of the horizontal groove 11 are connected to the curved arm 24 through bearings with seats. The horizontal groove 11 facilitates the rotation of the curved arm 24. The top of the T-shaped frame 23 and the outside of the curved arm 24 are uniformly connected to the rollers 26. The outside of the rollers 26 is fitted with rubber sleeves. The rollers 26 improve the positioning effect of the precast column.

[0027] The curved arm 24 is externally connected to a first spring 27, which is connected to the top of the inner cavity of the bracket 1. The first spring 27 facilitates the return of the curved arm 24 after rotation. Vertical grooves are provided on both the left and right sides of the threaded rod 21. The vertical grooves are slidably connected to the horizontal arm 33, which facilitates the horizontal arm 33 to slide up and down. A torsion wheel 35 is connected to the bottom of the square arm 31. The torsion wheel 35 has anti-slip texture on its outside, which facilitates the movement of the square arm 31 and the rotation of the threaded rod 21.

[0028] This solution first fixes the bracket 1, places the precast column on top of the roller 26, pulls the square arm 31 out of the inner cavity of the clamping rod 34, rotates the threaded rod 21, and then drives the nut 22 to rise, which in turn drives the T-shaped frame 23 and the trapezoidal block 25 to rise. The trapezoidal block 25 abuts against the bent arm 24 and rotates, finally driving the three rollers 26 to move relative to each other, fixing the precast column and determining the center of the precast column. At the same time, the square arm 31 returns to its original position through the second spring 32 and is inserted into the inside of the clamping rod 34, fixing the position of the square arm 31 and the threaded rod 21, and preventing the threaded rod 21 from being driven to rotate by the environment.

[0029] By adding threaded rod 21, nut 22, T-shaped bracket 23, trapezoidal block 25 and bent arm 24, the position of the precast column can be quickly fixed and the center position of the precast column can be located. This ensures that the position of the precast column is fixed when it is fixed by multiple devices, avoiding skew during fixing. At the same time, by adding square arm 31, second spring 32, horizontal arm 33 and locking rod 34, the position of the positioning mechanism 2 is automatically locked after the positioning mechanism 2 has positioned and fixed the precast column, preventing the positioning mechanism 2 from being driven by environmental factors and causing the positioning of the precast column to fail.
