Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially a high -strength prestressed static pressure square -tube pile construction positioning auxiliary device. BACKGROUND

[0002] In the construction engineering construction, high -strength prestressed static pressure square -tube pile because it has higher bearing capacity, construction noise is small, the periphery environment is little and so on the advantage, is widely used in the foundation engineering of all kinds of buildings. However, in the construction process of square -tube pile, accurate positioning is the key link of ensuring pile foundation engineering quality.

[0003] At present, the existing square -tube pile construction positioning method is mainly artificial survey positioning, then through hoisting equipment lifts the square -tube pile directly and stands on the positioning point, finally carries out static pressure construction, but, this way has following disadvantages:

[0004] In the process that hoisting equipment lifts the square -tube pile and places it on the positioning point, because the positioning point is small and not obvious, when the driver corresponds the square -tube pile with the positioning point, mainly relies on the voice instruction of survey personnel to operate, first, cannot directly see the positioning point, makes the driver operation more inconvenient, second, survey personnel stand near the positioning point and give voice instructions, are close to the square -tube pile, once the square -tube pile falls, can possibly hit survey personnel, therefore, the security risk is big. UTILITY MODEL CONTENTS

[0005] The utility model aims at at least solving one of the technical defects in the background art.

[0006] Therefore, one purpose of the utility model is to provide a high -strength prestressed static pressure square -tube pile construction positioning auxiliary device, which aims at solving the problem that the driver is inconvenient to operate when corresponding the square -tube pile with the positioning point in the static pressure square -tube pile construction in the prior art.

[0007] In order to realize the above -mentioned purpose, one embodiment of the utility model provides a high -strength prestressed static pressure square -tube pile construction positioning auxiliary device, which comprises a base and a top seat, the base comprises four insertion slots one, one side of the insertion slot one is fixedly connected with the insertion plate one, the side away from the insertion plate one of the insertion slot one is screw connected with the positioning bolt one, and the top of the insertion slot one is fixedly connected with the positioning column one.

[0008] The top seat comprises four insertion slots two, one side of the insertion slot two is fixedly connected with the insertion plate two, the side away from the insertion plate two of the insertion slot two is screw connected with the positioning bolt two, and the bottom of the insertion slot two is fixedly connected with the positioning column two.

[0009] The outer surface of the positioning column one is fixedly installed with a stand column, and the top end of the stand column is fixedly installed on the outer surface of the positioning column two.

[0010] The beneficial effects are as follows: After placing the device at the positioning point of the pile foundation, the driver can intuitively see the specific position of the device when performing static pressure construction on the square pipe pile. This allows the square pipe pile to be inserted from the middle of the top seat and base, and then statically pressed into the soil. Firstly, it makes it easier for the driver to see the positioning point, thus making the operation more convenient. Secondly, the surveyor can be further away from the positioning point, thereby improving safety. Thirdly, the dimensions of the base and top seat are adjustable, making it suitable for positioning assistance of square pipe piles of different sizes.

[0011] Preferably, in any of the above solutions, a threaded post is fixedly connected to the bottom of the slot one, and a support cylinder is threadedly connected to the outer surface of the threaded post.

[0012] The beneficial effects are as follows: Since static pressure construction is carried out on the ground, the ground is usually not very level. Therefore, by rotating the support cylinder, the height of slot one can be adjusted, thereby leveling the base of the device and ensuring that the square pipe pile can be pressed vertically into the soil.

[0013] Preferably, of any of the above solutions, a laser pointer or positioning pin is fixedly installed on the top of the slot one, a positioning cylinder is fixedly connected to the top of the slot one, an adjusting bolt is threadedly connected to the outer surface of the positioning cylinder, and a plug rod is fixedly connected to the outer surface of the laser pointer.

[0014] The beneficial effect is that by rotating the laser pointer, the laser beam it projects falls on the positioning pin, so that the laser beam is the diagonal of the rectangle in the middle of the base. Therefore, the intersection of the two laser beams is the center. When placing the device, the intersection is aligned with the positioning point of the pile foundation, so that the device is located directly above the positioning point of the pile foundation. This makes it convenient to align the device with the positioning point of the pile foundation.

[0015] Preferably, as described in any of the above schemes, the top of both the first insert plate and the second insert plate are provided with scale lines.

[0016] The beneficial effect is that when adjusting the size of the base and the top, the size of the rectangle in the middle of the base and the top can be intuitively judged by the scale lines on the first and second plates, thus facilitating the adjustment of the size of the base and the top.

[0017] Preferably, any of the above solutions also includes a laser line projector, and the outer surface of the column is provided with vertical and horizontal grooves.

[0018] The beneficial effects are as follows: After the positioning auxiliary device is set up on the pile foundation positioning point, the laser line projector is placed on one side of the base and leveled. Then, it projects vertical and horizontal lines. By adjusting the laser line projector, the vertical and horizontal lines are aligned with the vertical and horizontal grooves, respectively. During the static pressure of the square tube pile, if either the vertical or horizontal line does not coincide with the vertical or horizontal groove, it indicates that the square tube pile is tilted. Therefore, the construction personnel can make timely adjustments according to the situation to ensure the quality of construction.

[0031] This utility model provides a positioning auxiliary device for high-strength prestressed static pressure square tube pile construction.

[0032] Example 1:

[0033] like Figures 1-3 As shown, it includes a base 1 and a top seat 2. The base 1 includes four slots 11. A plate 12 is fixedly connected to one side of each slot 11. The four plates 12 are inserted into the interior of adjacent slots 11 to form the base 1. The length and width of the rectangle formed by the four plates 12 can be adjusted by sliding the plates 12 in the slots 11. The top of each plate 12 is provided with scale lines for easy viewing of the length and width of the rectangle. A positioning bolt 13 is threadedly connected to the side of the slot 11 away from the plate 12. By tightening the positioning bolt 13, the plate 12 can be fixed inside the slot 11, thereby achieving the purpose of fixing the length and width of the rectangle formed by the four plates 12. A positioning post 14 is fixedly connected to the top of the slot 11.

[0034] The top seat 2 includes four slots 21. A plate 22 is fixedly connected to one side of each slot 21. The four plates 22 are inserted into the interior of adjacent slots 21 to form the top seat 2. The length and width of the rectangle formed by the four plates 22 can be adjusted by sliding the plates 22 in the slots 21. The top of the plates 22 is provided with scale lines for easy viewing of the length and width of the rectangle. A positioning bolt 23 is threadedly connected to the side of the slots 21 away from the plates 22. By tightening the positioning bolt 23, the plates 22 can be fixed inside the slots 21, thereby achieving the purpose of fixing the length and width of the rectangle formed by the four plates 22. A positioning post 24 is fixedly connected to the bottom of the slots 21.

[0035] A column 3 is fixedly installed on the outer surface of positioning column 14. The top of the column 3 is fixedly installed on the outer surface of positioning column 24. Both the top and bottom of the column 3 have through holes. The outer surfaces of positioning column 14 and positioning column 24 also have through holes. By using a positioning pin to pass through the through holes on the column 3 and the positioning column, the column 3 and the positioning column can be fixed together, thereby fixing the base 1 and the top seat 2 together.

[0036] like Figures 1-2 As shown, a threaded post 15 is fixedly connected to the bottom of slot 11, and a support cylinder 16 is threadedly connected to the outer surface of the threaded post 15. By rotating the support cylinder 16 on the outer surface of the threaded post 15, the distance between the support cylinder 16 and slot 11 can be adjusted. Thus, when the ground at the construction site is uneven, the base 1 can be leveled by adjusting the support cylinder 16.

[0037] The working principle of this embodiment is as follows: During use, the base 1 and top seat 2 are adjusted according to the size of the square tube pile so that the length and width of the rectangle in the middle correspond to the length and width of the square tube pile. Then, the device is placed above the positioning point of the square tube pile, and the base 1 is leveled by adjusting the positioning cylinder 17. After the operator lifts the square tube pile, the square tube pile can be placed in the middle of the top seat 2 and the base 1 according to the position of the device. Then, static pressure construction is carried out to press the square tube pile into the ground. This device facilitates the observation of the pile foundation point.

[0038] Example 2:

[0039] like Figure 4 As shown, based on Embodiment 1, a laser pointer 4 or a positioning pin 5 is fixedly installed on the top of the slot 11. The laser pointer 4 illuminates the positioning pin 5 to form a laser beam. Two laser pointers 4 and two positioning pins 5 are installed on the four slots 11 respectively. The two laser pointers 4 emit two laser beams. The two laser beams are the diagonals of the rectangle formed by the four insert plates 12, so that the intersection of the two laser beams is the center of the rectangle.

[0040] Specifically, such as Figures 4-6 As shown, a positioning cylinder 17 is fixedly connected to the top of slot 11. An adjusting bolt 18 is threaded onto the outer surface of the positioning cylinder 17. A plug rod 41 is fixedly connected to the outer surface of the laser pointer 4. The laser pointer 4 is inserted into the positioning cylinder 17 through the plug rod 41. Then, by tightening the adjusting bolt 18, the plug rod 41 can be fixed, thereby fixing the laser pointer 4 onto the slot 11. The positioning pin 5 is directly inserted into the positioning cylinder 17. Then, the adjusting bolt 18 is tightened to fix the positioning pin 5.

[0041] The working principle of this embodiment is as follows: When using the device, after adjusting the size, loosen the adjusting bolt 18, rotate the laser pen 4 so that the laser beam emitted by it illuminates the corresponding positioning pin 5, then tighten the adjusting bolt 18 to fix the laser pen 4, and then place the device above the positioning point of the pile foundation. By observing the intersection of the two laser beams, make the intersection point correspond to the positioning point of the pile foundation, then put the device down and level the base 1 to carry out static pressure construction. This facilitates the alignment of the device with the positioning point of the pile foundation when it is placed.

[0042] Example 3:

[0043] like Figure 7 As shown, based on Embodiment 1 or Embodiment 2, a laser line projector 6 is also included, and the outer surface of the column 3 is provided with a vertical groove 31 and a horizontal groove 32. After the laser line projector 6 is leveled, it can project vertical and horizontal lines. Rotate the laser line projector 6 so that the projected vertical line coincides with the vertical groove 31, and adjust the height of the horizontal line so that the horizontal line coincides with the horizontal groove 32. Then, during the static pressure of the square tube pile, if either the vertical line or the horizontal line does not coincide with the vertical groove 31 or the horizontal groove 32, it indicates that the square tube pile has tilted. Therefore, the construction personnel can make timely adjustments according to the situation.

[0044] The working principle of this embodiment is as follows: When in use, the device is placed at the positioning point of the pile foundation and leveled. Then, the laser line projector 6 is placed on one side of the device and leveled. Then, vertical and horizontal lines are projected. By adjusting the laser line projector 6, the vertical and horizontal lines are made to coincide with the vertical groove 31 and the horizontal groove 32, respectively. Then, static pressure construction is carried out on the square pipe pile. During the construction process, if either the vertical line or the horizontal line deviates from the vertical groove 31 or the horizontal groove 32, it indicates that the square pipe pile has tilted. Therefore, it can be visually observed and judged, which is convenient for construction personnel to make timely adjustments and ensure the quality of construction.
