Description

Technical Field

[0001] This utility model belongs to the field of precast column installation technology, and in particular relates to a precast concrete column alignment device. Background Technology

[0002] Precast columns are concrete columns made by first preparing templates according to specified dimensions and then pouring concrete into them. Once they reach the required strength, they are used in the project. When using precast columns, they need to be placed in the socket of the factory building and concrete is poured. During this process, a leveling device is needed to ensure the verticality of the precast column.

[0003] Chinese utility model patent application number 201720608489.X discloses a device for quickly aligning precast columns, including a locking clamp and a jack, with the jack connected and positioned below the locking clamp. This utility model involves installing the precast column in a cup-shaped foundation, placing the jack on the foundation, and using the locking clamp to lock and fix the precast column. The jack's extension and retraction aligns the precast column; simply adjusting the jack completes the alignment process.

[0004] However, the aforementioned utility model patents still have some shortcomings:

[0005] In the process of using the above-mentioned utility model patent, the verticality of the precast column is adjusted by contracting the jack and striking the wedge at the cup opening with a sledgehammer. However, when the sledgehammer strikes the wedge at the cup opening, it can easily damage the concrete at the cup opening and affect the alignment accuracy. Utility Model Content

[0006] This utility model provides a precast concrete column alignment device, which aims to solve the problems mentioned in the background art.

[0007] This utility model is implemented as follows: a precast concrete column alignment device includes a locking assembly, which includes a pair of locking plates and a pair of locking plates. The locking plates are fastened to each other on the outside of the side wall of the precast column. A fixing plate is connected to the side wall of each locking plate and each locking plate. A jack is detachably connected to the bottom of the fixing plate. An auxiliary hole is vertically opened through the side wall of each locking plate and each locking plate. An auxiliary component is detachably installed in the auxiliary hole.

[0008] Preferably, the auxiliary component includes auxiliary rods, each of which is movably inserted into an auxiliary hole on the same locking plate. An auxiliary ball is detachably installed at the bottom of each auxiliary rod, and a cap is detachably installed at the top of each auxiliary rod. A cover plate is commonly installed on the caps.

[0009] Preferably, the auxiliary ball has a screw hole on its side wall, and the lower end of the auxiliary rod has a threaded groove on its side wall. The auxiliary ball is screwed onto the threaded groove through the screw hole and installed on the lower end of the auxiliary rod.

[0010] Preferably, the bottom of the cap is provided with a second screw hole, and the upper side wall of the auxiliary rod is provided with an upper thread. The cap is screwed onto the upper thread through the second screw hole and installed on the upper end of the auxiliary rod.

[0011] Preferably, the bottom of the cover plate has a cover groove, and the cover plate is placed on the top of the auxiliary rod through the cover groove and the cap.

[0012] Preferably, connecting plates are fixedly connected to the front and rear side walls of locking plate one, and connecting plates are fixedly connected to the center of the left and right side walls of locking plate two. Connecting plates two can be inserted between two connecting plates one, and threaded holes are opened on both connecting plates two and connecting plates one. Connecting plates one and connecting plates two are fastened together by bolts and nuts installed in the threaded holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Construction workers use jacks to control the fixed plate and move the corresponding locking plate vertically to adjust the angle of the tilted precast column within a larger range. After adjustment, auxiliary components are used to adjust the angle of the slightly tilted precast column within a smaller range, which improves the accuracy of the precast column alignment.

[0015] 2. Install an auxiliary component in the auxiliary hole on the locking plate at the opposite direction of the precast column's tilt. The auxiliary rod drives the auxiliary ball to move downwards and stops when it touches the side wall of the tilted precast column. The construction worker then uses a rubber hammer to strike the cover plate downwards, using the downward pressure on the auxiliary rod and auxiliary ball to tilt and correct the precast column until it is within the detection range of the surveying instrument. This method eliminates the need to use the cup opening to adjust the tilt direction of the precast column, thus avoiding damage to the precast column with the cup opening.

[0027] Please see Figure 1-3This utility model provides a technical solution: a precast concrete column alignment device, including a locking assembly 1. The locking assembly 1 includes a pair of locking plates 11 and a pair of locking plates 12. The locking plates 11 and 12 are fastened to each other on the side wall of the precast column. A fixing plate 18 is connected to the side wall of each locking plate 11 and each locking plate 12. A jack 3 is detachably connected to the bottom of the fixing plate 18. An auxiliary hole 19 is vertically opened through the side wall of each locking plate 11 and each locking plate 12. An auxiliary assembly 2 is detachably installed in the auxiliary hole 19.

[0028] Specifically, the precast column is placed in the cup-shaped foundation, and locking assembly 1 is installed on the outer wall of the precast column to lock it. The tilt angle and direction of the precast column are detected by a surveying instrument. Then, jack 3 is used to control the fixing plate 18 to move the corresponding locking plate in the vertical direction to make a large adjustment to the tilted precast column. After adjustment, auxiliary assembly 2 is used to make fine tilt adjustment to the slightly tilted precast column to improve the accuracy of the precast column alignment.

[0029] Furthermore, the auxiliary component 2 includes auxiliary rods 21, and each auxiliary rod 21 is movably inserted into the auxiliary hole 19 on the same locking plate. Each auxiliary rod 21 has an auxiliary ball 23 detachably installed at its bottom end and a cap 25 detachably installed at its top end. A cover plate 26 is commonly installed on the caps 25.

[0030] Specifically, an auxiliary component 2 is installed on the locking plate at the opposite direction of the precast column's tilt. The auxiliary rod 21 drives the auxiliary ball 23 to move downwards, stopping when it touches the side wall of the tilted precast column. The construction workers then use a rubber hammer to strike the cover plate 26 downwards, using the downward pressure on the auxiliary rod 21 and the auxiliary ball 23 to tilt and correct the precast column until it is within the detection range of the surveying instrument. This method eliminates the need to adjust the tilt direction of the precast column using the cup opening, thus avoiding damage to the precast column with the cup opening.

[0031] Furthermore, a screw hole 28 is provided on the side wall of the auxiliary ball 23, and a lower thread 22 is provided on the side wall of the lower end of the auxiliary rod 21. The auxiliary ball 23 is screwed onto the lower thread 22 through the screw hole 28 and installed at the lower end of the auxiliary rod 21.

[0032] Specifically, the auxiliary rod 21 is first inserted into the auxiliary hole 19, and then the auxiliary ball 23 is screwed to the lower end of the auxiliary rod 21; the auxiliary ball 23 has a large volume, which facilitates contact with the precast column.

[0033] Furthermore, the bottom of the cap 25 is provided with a screw hole 29, and the upper side wall of the auxiliary rod 21 is provided with an upper thread 24. The cap 25 is screwed onto the upper thread 24 through the screw hole 29 and installed on the upper end of the auxiliary rod 21.

[0034] Specifically, after the auxiliary rod 21 is inserted into the auxiliary hole 19, a cap 25 is screwed onto the upper end of each auxiliary rod 21 in sequence; the size of the cap 25 is larger than the size of the auxiliary hole 19 to prevent the auxiliary rod 21 from falling out of the auxiliary hole 19 into the cup base.

[0035] Furthermore, a cover groove 27 is provided at the bottom of the cover plate 26, and the cover plate 26 is placed on the top of the auxiliary rod 21 through the cover groove 27 and the cap 25.

[0036] Specifically, the cover plate 26 is placed on all the caps 25. When the cover plate 26 is struck downwards with a rubber hammer, pressure can be applied to all the auxiliary rods 21 at the same time to make a slight adjustment to the tilt angle of the precast column.

[0037] Furthermore, connecting plates 13 are fixedly connected to the front and rear side walls of locking plate 11, and connecting plates 24 are fixedly connected to the center of the left and right side walls of locking plate 22. Connecting plates 24 can be inserted between the two connecting plates 13, and threaded holes 15 are opened on both connecting plates 24 and connecting plates 13. Bolts 16 and nuts 17 are installed in the threaded holes 15 to fasten connecting plates 13 and 24 together.

[0038] Specifically, bolts 16 are sequentially screwed into the upper connecting plate 13, the middle connecting plate 2 14, and the lower connecting plate 13. Nuts 17 are screwed into the lower side wall of bolts 16 to fasten connecting plates 13 and 2 14 together. In this way, locking plates 11 and 2 12 can be used to lock the side wall of the precast column, so as to facilitate a wide range of tilt angle adjustment of the precast column.

[0039] In addition, the appropriate locking plate 11 and locking plate 22 can be selected according to the size of the precast column, which improves the practicality of the device.

[0040] The working principle and usage process of this utility model are as follows: After the utility model is installed, the bolt 16 is sequentially screwed into the upper connecting plate 13, the middle connecting plate 2 14 and the lower connecting plate 13. The nut 17 is screwed into the lower side wall of the bolt 16 to fasten the connecting plate 13 and the connecting plate 2 14 together. In this way, the side wall of the precast column can be locked by using the locking plate 11 and the locking plate 2 12.

[0041] The tilt angle and direction of the precast column are detected by a surveying instrument, and then the jack 3 is used to control the fixing plate 18 to move the locking plate in the corresponding tilt direction in the vertical direction, so as to make a large range of angle adjustment for the tilted precast column.

[0042] Under the inspection of the surveying instrument, after a wide range of angle adjustments, continue to observe whether there is a small angle of tilt in the precast column. Insert auxiliary rods 21 into the auxiliary holes 19 of the locking plate in the opposite direction of the tilt of the precast column. First, screw the cap 25 to the upper end of the auxiliary rod 21, then screw the auxiliary ball 23 to the lower end of the auxiliary rod 21, and finally put the cover plate 26 on the cap 25.

[0043] Move the auxiliary rod 21 downwards until the auxiliary ball 23 touches the side wall of the inclined precast column and stops. The construction workers use a rubber hammer to strike the top of the cover plate 26 to apply downward pressure to the auxiliary rod 21 and the auxiliary ball 23 to tilt and correct the precast column until it is within the detection range of the surveying instrument, thus completing the alignment of the precast column.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
