Description

Technical Field

[0001] This utility model belongs to the field of steel support anchor bolt pre-embedding and positioning technology, and in particular relates to an anchor bolt pre-embedding and positioning device. Background Technology

[0002] When mechanical components are installed on a concrete foundation, the J-shaped or L-shaped end of the bolt is embedded in the concrete. The tensile strength of the anchor bolt is the tensile strength of the round steel itself, which is equal to the cross-sectional area multiplied by the allowable stress value, and is the allowable tensile bearing capacity in the design.

[0003] In the process of anchor bolt positioning, concrete blocks or positioning frames are often inserted into the reinforcing cage to position the pre-embedded anchor bolt steel pipe. However, concrete blocks or positioning frames cannot be reused and will shake during the positioning process along with the poured concrete, resulting in insufficient positioning accuracy. Therefore, we propose an anchor bolt pre-embedded positioning device, which uses an adjustable positioning plate locked onto the anchor bolt steel pipe. The outer side of the positioning plate abuts against the inner wall of the outer support cylinder, which can quickly and accurately locate the pre-embedded anchor bolt steel pipe in the foundation structure. Utility Model Content

[0004] The purpose of this utility model is to provide an anchor bolt pre-embedded positioning device, which has the advantage of using an adjustable positioning plate locked onto the anchor bolt steel pipe, with the outer side of the positioning plate abutting against the inner wall of the outer support cylinder, to quickly and accurately locate the pre-embedded anchor bolt steel pipe in the foundation structure. This solves the problem that in the process of anchor bolt positioning, concrete blocks or positioning frames are often inserted into the reinforcing cage to achieve the positioning of the pre-embedded anchor bolt steel pipe. However, concrete blocks or positioning frames cannot be reused and will shake during the positioning process along with the poured concrete, resulting in insufficient positioning accuracy.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A pre-embedded anchor bolt positioning device includes multiple pre-embedded reinforcing bar bolt tubes bound inside the foundation reinforcing bar cage by steel wires. The top of the pre-embedded reinforcing bar bolt tubes extends to the top of the foundation reinforcing bar cage. A positioning and locking assembly is provided on the surface of the pre-embedded reinforcing bar bolt tubes. An outer support cylinder is provided on the outside of the foundation reinforcing bar cage. The positioning and locking assembly includes a steel pipe sleeve fitted onto the end of the surface of the pre-embedded reinforcing bar bolt tubes. A fixing plate is fixedly connected to the surface and top of the steel pipe sleeve. An extension plate is provided on one side of each of the two fixing plates. A connecting plate is fixedly connected between the two extension plates. A vertical plate is fixedly connected between the two fixing plates. A nut is fixedly connected to one side of the vertical plate. A threaded post is threadedly connected to the inner cavity of the nut. One end of the threaded post is rotatably connected to the connecting plate.

[0006] The present invention further comprises, as described above, a positioning device for pre-embedded anchor bolts, wherein a handwheel is fixedly installed at the end of the threaded post away from the connecting plate.

[0007] The present invention further comprises the following: a guide rod is fixedly connected to one side of the connecting plate, and one end of the guide rod extends through to one side of the upright plate and is slidably connected to the upright plate.

[0008] The present invention further comprises the following: a second nut is fixedly connected to one side of the connecting plate, and a second threaded post is threadedly connected to the inner cavity of the second nut. One end of the second threaded post penetrates into the inner cavity of the steel pipe sleeve and abuts against the surface of the pre-embedded steel bolt pipe.

[0009] The present invention further comprises the following: the surface of the steel pipe sleeve is provided with a through hole for the threaded post to pass through.

[0010] The present invention further comprises, as described above, a positioning device for pre-embedded anchor bolts, wherein a handwheel is fixedly installed at the end of the threaded post two away from the steel pipe sleeve.

[0011] The present invention further comprises, as described above, a positioning device for pre-embedded anchor bolts, wherein the protruding end of the extension plate abuts against the inner wall of the outer support cylinder.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model involves pre-measuring the distance between the pre-embedded steel bolt pipe and the inner wall of the outer support cylinder, rotating the threaded column one, and causing the threaded column one to move and rotate due to the nut one, thereby pushing the connecting plate and the extension plate to move, so that the extension plate moves out between the two fixed plates until it is adjusted to a suitable position. Then, the fixed plate is lifted so that the steel pipe is sleeved on the pre-embedded steel bolt pipe, and the extension plate abuts against the inner side of the outer support cylinder to position the pre-embedded steel bolt pipe. Then, the threaded column two is tightened to restrict the rotation and movement of the steel pipe sleeved on the surface of the pre-embedded steel bolt pipe, so that the extension plate is firmly secured. Firmly pressed against the inner wall of the outer support cylinder, precise positioning is achieved. This is achieved by using an adjustable positioning plate locked onto the anchor bolt steel pipe, with the outer side of the positioning plate pressing against the inner wall of the outer support cylinder. This allows for the rapid and accurate positioning of the pre-embedded anchor bolt steel pipe in the foundation structure. It solves the problem that the common method of using concrete blocks or positioning frames inserted into the reinforcing cage to position the pre-embedded anchor bolt steel pipe has drawbacks. These methods are not reusable and the positioning accuracy is insufficient due to the shaking that occurs during the pouring of concrete.

[0014] 2. By setting a guide rod, the connecting plate moves and drives the guide rod to slide on the upright plate, which can guide and limit the movement of the connecting plate, effectively preventing the connecting plate from deviating during the movement, improving the stability of the connecting plate movement, and thus ensuring the stability of the extension plate.

[0015] 3. The present invention, through the setting of the through hole, facilitates the threaded post two to pass through the through hole and enter the inner cavity of the steel pipe sleeve to abut against the steel pipe sleeve, thereby restricting the rotation and up-down movement of the steel pipe sleeve by friction.

[0028] Example 2

[0029] Figure 1-4This invention illustrates an embodiment of an anchor bolt pre-embedded positioning device, comprising multiple pre-embedded reinforcing bar bolt tubes 2 bound together with steel wire inside a foundation reinforcing cage 1. The tops of the pre-embedded reinforcing bar bolt tubes 2 extend to the top of the foundation reinforcing cage 1. A positioning and locking assembly 3 is provided on the surface of the pre-embedded reinforcing bar bolt tubes 2. An outer support cylinder 4 is provided on the outside of the foundation reinforcing cage 1. The positioning and locking assembly 3 includes a steel pipe sleeve 31 fitted onto the end of the surface of the pre-embedded reinforcing bar bolt tubes 2. Fixing plates 32 are fixedly connected to the surface and top of the steel pipe sleeve 31. Extension plates 33 are provided on opposite sides of the two fixing plates 32. A connecting plate 34 is fixedly connected between the two extension plates 33. A vertical plate 35 is fixedly connected between the two fixing plates 32. A nut 36 is fixedly connected to one side of the vertical plate 35. The inner surface of the nut 36... The cavity is threaded with a threaded post 37. One end of the threaded post 37 is rotatably connected to the connecting plate 34. A nut 310 is fixedly connected to one side of the connecting plate 34. A threaded post 311 is threadedly connected to the inner cavity of the nut 310. One end of the threaded post 311 penetrates into the inner cavity of the steel pipe sleeve 31 and abuts against the surface of the pre-embedded steel bolt pipe 2. A through hole 313 is opened on the surface of the steel pipe sleeve 31 for the threaded post 311 to pass through. The through hole 313 facilitates the threaded post 311 to pass through the through hole 313 and enter the inner cavity of the steel pipe sleeve 31 to abut against the steel pipe sleeve 31. The friction restricts the rotation and up and down movement of the steel pipe sleeve 31. A handwheel 312 is fixedly installed at the end of the threaded post 311 away from the steel pipe sleeve 31. The protruding end of the extension plate 33 abuts against the inner wall of the outer support cylinder 4.

[0030] Working principle: When using this utility model, based on the pre-embedded steel bolt pipe 2 and the outer support cylinder 4, the user operates the handwheel 38 to drive the threaded column 37 to rotate. Due to the nut 36, the threaded column 37 moves and rotates, thereby pushing the connecting plate 34 and the extension plate 33 to move, so that the extension plate 33 moves out between the two fixed plates 32 until it is adjusted to a suitable position. Then, the fixed plate 32 is lifted, so that the steel pipe sleeve 31 is put on the pre-embedded steel bolt pipe 2, so that the extension plate 34 moves out of the two fixed plates 32. 3 is placed against the inner side of the outer support cylinder 4 to position the pre-embedded steel bolt pipe 2. Then, the handwheel 312 is turned to rotate the threaded column 311. Due to the nut 310, the threaded column 311 moves and rotates towards the pre-embedded steel bolt pipe 2. The threaded column 311 passes through the through hole 313 and abuts against the pre-embedded steel bolt pipe 2, restricting the steel pipe sleeve 31 from rotating and moving on the surface of the pre-embedded steel bolt pipe 2. This makes the extension plate 33 firmly abut against the inner wall of the outer support cylinder 4, achieving precise positioning.

[0031] In summary: This anchor bolt pre-embedded positioning device, based on the pre-measured distance between the pre-embedded reinforcing bar bolt pipe 2 and the inner wall of the outer support cylinder 4, rotates the threaded column 37. The nut 36 causes the threaded column 37 to move and rotate, thereby pushing the connecting plate 34 and the extension plate 33 to move. This causes the extension plate 33 to move out between the two fixed plates 32 until it is adjusted to a suitable position. Then, the fixed plates 32 are lifted, allowing the steel pipe sleeve 31 to be fitted onto the pre-embedded reinforcing bar bolt pipe 2, so that the extension plate 33 abuts against the inner side of the outer support cylinder 4, thus positioning the pre-embedded reinforcing bar bolt pipe 2. Finally, the threaded column 311 is tightened to restrict the steel pipe sleeve 31 from being positioned within the pre-embedded reinforcing bar. The surface of the bolt pipe 2 rotates and moves, causing the extension plate 33 to firmly abut against the inner wall of the outer support cylinder 4, achieving precise positioning. This allows for the use of an adjustable positioning plate locked onto the anchor bolt steel pipe, with the outer side of the positioning plate abutting against the inner wall of the outer support cylinder. This enables the precise positioning of the pre-embedded anchor bolt steel pipe in the foundation structure, solving the problem that the positioning process often involves using concrete blocks or positioning frames inserted into the reinforcing cage to achieve the positioning of the pre-embedded anchor bolt steel pipe. However, these concrete blocks or positioning frames cannot be reused and may shake during the positioning process due to the pouring concrete, resulting in insufficient positioning accuracy.

[0032] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
