Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a device for controlling the verticality of precast pile construction. Background Art

[0002] A precast pile is a concrete pile that is prefabricated and pre-pressed in a specialized factory in advance according to design requirements before construction, and then transported to the construction site for installation through a transportation tool. To improve the bearing capacity and stability of the foundation, reduce the risk of foundation settlement and soil lateral displacement, precast piles are often driven into the soil layer of the building foundation as a part of the building foundation. On the one hand, precast piles have extremely high bearing capacity. They can effectively bear the weight of large buildings and disperse these loads into the foundation, thus ensuring the stability and safety of the building structure. On the other hand, since the precast piles penetrate into the bearing layer required by the design, they can provide a solid foundation for the building and reduce the damage caused to the building by foundation settlement.

[0003] During the construction of precast piles, the verticality of the precast piles inserted into the foundation soil layer should be ensured. On the one hand, precast piles with good verticality with the foundation soil layer can effectively transfer the load of the upper building structure to the deep and stable soil layer, thereby improving the overall bearing capacity of the precast piles. On the other hand, when the precast piles are perpendicular to the foundation soil layer, the precast piles are more evenly stressed, which can enhance the stability of the entire building structure. At the same time, it can avoid uneven settlement of the precast piles during the later use process, threatening the safety of the entire building structure.

[0004] During the construction of precast piles, first, a trench is dug in the foundation soil layer. Secondly, a pile hole is drilled in the trench through a spiral drilling machine, the precast pile is inserted into the pile hole through a crane, and finally, grout is injected into the pile hole. By injecting grout, the soil around the pile is reinforced, the soil bearing capacity is improved, the settlement of the pile foundation is reduced, and at the same time, the influence of groundwater seeping into the pile hole on the stability and durability of the pile is prevented.

[0005] Since the inner diameter of the pile hole is generally larger than the diameter of the precast pile, and the injected grout is relatively soft before solidification and has no supporting force on the precast pile. Therefore, the precast pile often tilts after being inserted into the pile hole. To ensure the verticality of the precast pile in the pile hole, the commonly used method in construction at present is: obliquely arranged support rods are provided on the circumference of the precast pile. One end of the support rod abuts against the precast pile, and the other end is inserted into the soil layer on both sides of the trench to realize the oblique support of the precast pile. At the same time, a plumb bob is tied to the precast pile, and by observing the verticality of the plumb bob, the support rod is adjusted to calibrate the verticality of the precast pile.

[0006] During the construction of the verticality of existing precast piles, after the precast pile is inserted into the pile hole, since the diameter of the pile hole is larger than that of the precast pile, the inclination of the precast pile is often large, and the adjustment range of the verticality of the precast pile is also often large. At the same time, when adjusting the verticality of the precast pile, multiple workers need to manually push and support it with the cooperation of a crane for adjustment. After adjusting to the appropriate position, a support rod for setting an inclined support is fixed. The problem existing in the construction process of the verticality of the existing precast pile is that the inclination of the precast pile is large after it is inserted into the pile hole, and the method of adjusting the verticality by manually cooperating with a crane is rather troublesome. After adjustment, an inclined support needs to be installed for fixation, and the construction is rather troublesome. Summary of the Invention

[0031] To make the above - mentioned objects, features and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0032] The terms "including" and "having" and any variations thereof in the present application are intended to cover non - exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0033] Referring to "embodiment" herein means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0034] Such as Figure 1As shown in the figure, a verticality control device 100 for precast pile construction of the present utility model includes a pile body connection part 1, an adjustment part 2, and a fixing part 3. The pile body connection part 1 includes a plurality of plate bodies 4 arranged in sequence along the length direction of the precast pile and a connecting body 5 disposed between two adjacent plate bodies 4. Each plate body 4 is perpendicular to the length direction of the precast pile. As Figure 2 shown, each plate body 4 is provided with a first through hole 6 for passing through and limiting the precast pile, and the connecting body 5 is arranged along the circumferential direction of the first through hole 6. In one embodiment, the precast pile is a cylindrical pile and the first through hole 6 is a circular hole. In another embodiment, the precast pile is a cube and the first through hole 6 is a square hole. The size of the first through hole 6 is set to be slightly larger than the outer dimension of the precast pile, so that after the precast pile is inserted into the first through hole 6, it can only shake slightly, and the precast pile is roughly limited in the first through hole 6. The adjustment part 2 includes a plurality of adjusting members 21 arranged on the connecting body 5. One end of the adjusting member 21 is used to abut against the precast pile. The adjusting member 21 is horizontally arranged, and the arrangement directions of the respective adjusting members 21 are different. The adjusting member 21 can move along the length direction parallel to the precast pile, and the abutting end of each adjusting member 21 can move along the length direction of the adjusting member 21. One end of the fixing part 3 is fixedly connected to the pile body connection part 1, and the other end is fixed on the ground.

[0035] During construction organization, first, the verticality control device 100 for precast pile construction of the present utility model is erected at both ends of the trench and fixed on the ground through the fixing part 3, and the whole device is leveled to ensure that the plate body 4 is horizontal. The first through hole 6 on the plate body 4 corresponds to the pile hole, and the precast pile is inserted into the first through hole 6 by a crane. Then, the adjustment part 2 is adjusted to finely adjust the inclination of the precast pile, so as to vertically insert the precast pile into the foundation soil layer. By means of the present utility model, after the precast pile is inserted into the pile hole, the crane can be removed, and only a few workers need to adjust the adjustment part 2 to adjust the verticality of the precast pile. It solves the problem that in the prior art, after the precast pile is inserted into the hole, a large number of workers are required to adjust the verticality of the precast pile in cooperation with the crane. At the same time, under the limiting action of the pile body connection part 1 and the adjustment part 2, there is no need to repeatedly install the support rods of the inclined support, which simplifies the construction process.

[0036] When the precast pile is abutted by the adjustment part 2 and the precast pile is "righted", due to the large friction force between the precast pile and the adjusting member 21, the adjusting member 21 will leave a large scratch on the precast pile, causing damage to the precast pile. Therefore, the adjustment part 2 further includes a rolling member 22 arranged at one end of the adjusting member 21 that abuts against the precast pile. The rolling member 22 is used to roll when moving on the abutting surface where the adjusting member 21 abuts against the precast pile. By providing the rolling member 22, when the adjusting member 21 "rights" the precast pile, the relative movement between the adjusting member 21 and the precast pile is replaced by rolling, avoiding damage to the precast pile by the adjusting member 21 and avoiding adverse effects on the service life of the precast pile.

[0037] In one embodiment, the connecting body 5 includes a plurality of columns, and each column is perpendicular to the plate body 4. By setting the connecting body 5 as columns, while having a supporting effect on the plate body 4, the cost is also relatively low. In another embodiment, the connecting body 5 is a cylindrical barrel provided outside the first through hole 6. The cylindrical barrel can have a good supporting effect on the plate body 4.

[0038] When the connecting body 5 is a column, in order to make the abutting effect of the adjusting part 2 provided on the connecting body 5 on the precast pile better. The number of columns is 4, and the 4 columns are evenly arranged along the circumference of the first through hole 6, and the connecting lines of the column centers of the cross-sections of the columns form a square.

[0039] In the precast pile construction verticality control device of the present utility model, a through groove parallel to the length direction of the precast pile is provided on the connecting body 5. The adjusting member 21 includes a first split body and a second split body. The first split body is defined on the connecting body 5 and can only move along the through groove. The second split body is connected to the first split body and can move away from or close to the precast pile relative to the first split body.

[0040] In one embodiment, as Figure 3 shown, the connecting body 5 is a channel steel. Two baffles parallel to the bottom surface of the channel steel are oppositely provided at the opening of the channel steel. The first split body is a bolt 211, and the nut of the bolt 211 is defined in the groove of the channel steel. Under the blocking effect of the baffle, the bolt 211 can only move along the length direction of the channel steel. The screw rod of the bolt 211 extends out of the groove of the channel steel and extends towards the precast pile. A movable nut 212 that can move along the length direction of the screw rod is provided on the screw rod. The bolt 211 is fixed at a specific position on the channel steel by clamping the baffle with the nut. The second split body is a sleeve 213 sleeved on the screw rod. The sleeve 213 is provided with internal threads, and the sleeve 213 is threadedly connected to the screw rod. By rotating the sleeve 213, the sleeve 213 moves towards the precast pile and abuts against the precast pile. For the convenience of rotating the sleeve 213, a first handle 214 is provided on the sleeve 213. The rolling member 22 is a ball. A groove is provided at one end of the sleeve 213 that abuts against the precast beam, and the ball is defined in the groove. The depth of the groove is greater than the radius of the ball. When the verticality of the precast pile needs to be adjusted, after fixing the bolt 211 at a specific position, the sleeve 213 is rotated to make the adjustment of the verticality of the precast pile more accurate.

[0041] In the precast pile construction verticality control device 100 of the present utility model, the fixing part 3 includes a plurality of inclined plates 31 and a horizontal plate 32 parallel to the plate body 4. Both sides of each inclined plate 31 are respectively connected to a plate body 4 and the horizontal plate 32. The fixing part 3 further includes a mounting member 33 connected to the horizontal plate 32, and the mounting member 33 is used to fix the horizontal plate 32 to the ground. Through the above settings, each plate body 4 can be connected to the ground, enhancing the stability of the entire precast pile construction verticality control device 100 after being fixed to the ground.

[0042] In one embodiment, the horizontal plate 32 is provided with a second through hole, and the mounting member 33 is a reinforcing nail passing through the second through hole. Through the above settings, the fixing part 3 can be more easily fixed to the ground and is easy to operate.

[0043] In one embodiment, the second through hole is provided with internal threads, the outer surface of the reinforcing nail is provided with external threads, and the reinforcing nail is threadedly connected to the second through hole. A second handle 7 for rotating the reinforcing nail is provided at one end of the reinforcing nail away from the ground. When it is necessary to insert or pull out the reinforcing nail from the ground, the reinforcing nail can be rotated by relying on the handle. When inserting the reinforcing nail into the ground, there is no need to hammer it with a hammer, and when pulling out the reinforcing nail from the ground, there is no need to rely on a crane, making the operation more convenient.

[0044] In order to facilitate the insertion and extraction of the reinforcing nail more conveniently, in one embodiment, a horizontal through hole is provided at the bottom end of the reinforcing nail away from the ground. When inserting and extracting the reinforcing nail, another reinforcing bar can be inserted into the horizontal through hole, and by leveraging the lever principle, the insertion and extraction of the reinforcing nail are made more labor-saving.

[0045] The precast pile construction verticality control device 100 of the present utility model further includes a level provided on the plate body 4. By providing the level, there can be a more accurate reference basis when adjusting the overall level of the device and ensuring the horizontality of the plate body 4. In one embodiment, the level is a circular bubble level. When the bubble is located at the center mark of the level, the plate body 4 is in a horizontal state. In another embodiment, the level is four strip bubble levels, and the connection lines of the four levels form a rectangle. When the bubbles in each level are all located at the middle position of the long strip, the plate body 4 is in a horizontal state.

[0046] The verticality control device 100 for precast pile construction of the present utility model further includes a laser instrument for emitting a laser mark at a target position, and the target position is the target center position of the precast pile. During specific construction, a cross-shaped mark can be set at one end of the precast pile that is exposed above the ground in the length direction of the precast pile. When the laser mark is at the center position of the cross-shaped mark, the precast pile is in a state perpendicular to the ground. The above embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
