Description

Technical Field

[0001] The utility model relates to the technical field of line-setting and positioning piles, in particular to a line-setting and positioning pile for building construction. Background Art

[0002] The construction process involves a wide range of areas. In the foundation treatment process, it is usually necessary to level the site, and then conduct subsequent construction after water and electricity are turned on. The leveled construction site needs to be measured and laid out to define the scope of the foundation for construction. Among them, the positioning of the pile foundation is involved. The current method of locating the pile foundation is to drive the wooden pile into the leveled site, nail the nails on the upper end, and then draw a wire to determine the working range. The existing positioning pile foundation has the problem that the wooden piles cannot be reused, and the multiple wooden piles after being driven into the soil are not convenient for adjusting the axis. In addition, the method of driving the wooden piles first and then positioning the nails and laying out the lines has a large positioning error. For this reason, Application No.: 20 1821272600.3 discloses a positioning pile for construction, which includes a positioning pile and a positioning rod. The positioning rod is placed in the cavity of the positioning pile of a rod-shaped structure, and the positioning rod is pressed into the soil along with the positioning pile. The pile foundation axis is checked by using the verification hole of the positioning pile as a reference point. After the verification, the positioning pile is pulled out and the positioning rod is left in the soil as the pile foundation center positioning point. The device overcomes the problems of the original pile foundation positioning and setting out using wooden piles and nails for positioning, which are not reusable, inconvenient to adjust, and have large errors. The device has the characteristics of simple structure, reusable positioning piles and positioning rods, convenient axis verification and adjustment, and high positioning and setting out accuracy.

[0003] The above patent discloses a layout positioning pile for construction. After positioning, the positioning pile is pulled out and the positioning rod is left in the soil as the center positioning point of the pile foundation. This method has some shortcomings when used: 1. The positioning rod is located inside the positioning pile. When the positioning pile is pulled out, there is a certain distance gap between the soil and the positioning rod. Therefore, after the positioning pile is pulled out, it is easy to cause soil collapse due to the distance gap, and the soil will squeeze the positioning rod and tilt it, thereby affecting the positioning effect; 2. When the positioning pile is pulled out upward and separated from the positioning rod, since the positioning rod has only the friction force of vertically inserting into the soil, there is a situation where the positioning rod moves upward with the positioning pile due to the friction between the positioning pile and the positioning rod, and personnel are required to re-position the operation; based on the above situation, a new design is made, and thus we propose a layout positioning pile for construction.

The mounting block 101, the pressing block 2 and the positioning pile body 1 are all movably sleeved on the driving rod 5, wherein the top of the positioning pile body 1 is provided with a first movable hole, the top of the pressing block 2 is provided with a second movable hole, the bottom inner wall of the T-shaped inspection hole 102 is provided with a third movable hole, and the top inner wall of the rectangular groove 3 is provided with a fourth movable hole.

[0026] The mounting block 101 is magnetically fixed to the top of the pressing block 2, wherein the top of the pressing block 2 is provided with two grooves, the bottom inner wall of the groove is fixedly connected with a first magnet 16, and the bottom of the mounting block 101 is fixedly connected with two second magnets, the second magnets are movably sleeved in the corresponding grooves and adsorbed with the top of the first magnet 16, and the mounting block 101 can be quickly fixed by the first magnet 16 and the second magnet, so that the mounting block 101 can be removed later to remove the shielding of the driving rod 5;

[0027] A buffer cotton 15 is fixedly connected to the top of the mounting block 101, and a first through hole connected to the T-shaped inspection hole 102 is opened on the top of the buffer cotton 15. The setting of the buffer cotton 15 can alleviate the buffering force during knocking, thereby achieving the effect of seismic isolation of the mounting block 101; the utility model can limit the vertical position of the positioning rod 100 through the setting of a series of structures, and can effectively avoid the situation in which the positioning rod 100 moves up along with the positioning pile body 1 during the upward movement, and the positioning pile body 1 is set inside the positioning rod 100. In the process of pulling out the positioning pile body 1, the positioning rod 100 and the soil are still in close contact and are not affected, thereby improving the stability of the positioning rod 100 and not affecting the subsequent continued precise positioning operation.

[0028] Working principle: When in use, when the positioning rod 100 is inserted into the positioning position, the installation block 101, the pressing block 2, the positioning rod 100 and the positioning pile body 1 can be driven to move downward by knocking the buffer cotton 15, and the positioning rod 100 is gradually inserted into the soil. The setting of the buffer cotton 15 can effectively buffer and isolate the impact force of the knocking, and reduce the situation where the installation block 101 is damaged by knocking. When the positioning rod 100 is inserted downward to the required depth, after multiple positioning rods 100 are inserted, the laser instrument can be used to align the T-shaped inspection hole 102 and emit a laser beam for detection, so that all the inserted positioning rods 100 are at the same height, thereby improving the laying-out accuracy;

[0029] After the measurement, the mounting block 101 can be pulled upward, and the mounting block 101 drives the two second magnets to separate upward from the two first magnets 16, thereby releasing the shielding of the driving rod 5. Then, the driving rod 5 can be pressed downward. While the driving rod 5 moves downward, it squeezes the rectangular block 4 to move downward. The rectangular block 4 squeezes the two squeezing rods 8 to move downward and rotate. Under the rotating squeezing force, the squeezing rod 8 squeezes the corresponding horizontal insertion rod 7 out of the mounting hole 6 and inserts it horizontally into the soil. When the driving rod 5 moves downward to be flush with the top of the pressing block 2, the pressing of the driving rod 5 is stopped. At this time, the two horizontal insertion rods 7 can limit the vertical position of the positioning rod 100.

[0030] Then, the pressing block 2 can be pulled upwards through the two first pull rings 12, and the pressing block 2 drives the positioning pile body 1 to separate upward from the positioning rod 100. At this time, the horizontal insertion rod 7 limits the vertical position of the positioning rod 100, and the positioning rod 100 cannot be brought out when the positioning pile body 1 moves upward, thereby improving the stability of the positioning rod 100. In addition, since the positioning pile body 1 is located inside the positioning rod 100, when the positioning pile body 1 is pulled out upward, the outer side of the positioning rod 100 is still in close contact with the soil and is not affected, and the soil will not squeeze the positioning rod 100 to deviate, thereby further improving the stability of the positioning rod 100 and not affecting the subsequent continued accurate positioning operation;

[0031] When the positioning rod 100 needs to be pulled out for pile foundation drilling, the driving rod 5 can be pulled upward, and the driving rod 5 drives the rectangular block 4 to move upward. While the rectangular block 4 moves upward, the two extrusion rods 8 drive the two cross-insertion rods 7 to move in a direction close to each other and retract into the installation hole 6, thereby releasing the vertical restriction on the positioning rod 100. At this time, the positioning rod 100 can be directly pulled out of the soil through the two second pull rings 13. When the positioning rod 100 is pulled out, a hole will be left in the soil, and drilling operations can be performed later.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
