Description
Technical Field
[0001] The present application relates to the technical field of building piles, and in particular to a preassembled pile structure for construction. Background Art
[0002] As an important form of deep foundation for buildings, precast piles are widely used in the construction industry. With the continuous advancement of engineering technology, new steel piles and reinforced concrete piles are increasingly being used in engineering construction due to their excellent performance.
[0003] During the installation of precast piles, the verticality of the pile position is a key factor in ensuring its supporting performance and use effect. However, in the existing precast pile construction process, especially when the hammer method is used for construction, the hammer method relies on heavy objects to hit the top of the pile body to make it sink into place. However, this method can easily cause the pile body to deviate when hit by heavy objects, causing the pile body to shift and tilt when it is driven into the foundation, seriously affecting the installation quality and stability of subsequent foundation construction.
[0004] At present, although there are some solutions in the engineering field that try to solve this problem, such as improving construction technology and optimizing pile design, these solutions are often limited in effect and cannot fundamentally solve the problem of pile displacement. Therefore, how to effectively prevent the prefabricated piles from deflecting during the hammering construction process and ensure the verticality of the pile has become a technical problem that needs to be solved urgently in the current engineering technology field. Utility Model Content
[0005] In order to effectively reduce the possibility of the pile body being deflected during the driving process, the present application provides a preassembled pile body structure for construction.
[0006] The present application provides a preassembled pile structure for construction using the following technical solution:
[0007] A prefabricated pile structure for construction comprises a prefabricated pile and a base plate for limiting the position of the prefabricated pile, wherein a through hole is vertically opened in the middle of the base plate for the prefabricated pile to pass through, and a plurality of brackets are distributed circumferentially around the through hole on the base plate, each of the brackets is bent toward the prefabricated pile, a vertical groove is opened on the outer side wall of the prefabricated pile body corresponding to the top end of each bracket, the vertical groove extends to the bottom wall of the prefabricated pile body, the top end of the bracket is located in the corresponding vertical groove, and vertically slides with the vertical groove.
[0008] By adopting the above technical solution, during the installation of the prefabricated pile body, the base plate is first placed at a predetermined position, and the positioning pile is inserted into the positioning hole to fix the base plate. Subsequently, the prefabricated pile body is passed through the through hole of the base plate, ensuring that the top of the bracket is aligned and inserted into the vertical groove on the outer wall of the prefabricated pile body. During the hammering construction process, the impact force of the heavy object on the top of the prefabricated pile body will drive the prefabricated pile body to move downward. At this time, the top of the bracket slides in the vertical groove, effectively limiting the deviation of the prefabricated pile body and ensuring its verticality.
[0009] The movable plate is provided with a plurality of grooves on the side walls of the movable plate, and the grooves on the fixed plate and the movable plate correspond to each other vertically. The movable plate comprises a connecting rod hinged in the installing groove, a connecting block arranged on two connecting rod ends relative to each other, and a top column arranged on the side of the connecting block facing the inner wall of the precast pile body. When the movable plate moves toward the fixed plate, the connecting rods arranged relatively on the fixed plate and the movable plate push the connecting block to move in the direction toward the inner wall of the precast pile body until the top column contacts the inner wall of the precast pile body.
[0010] By adopting the above technical solution, when the movable plate moves up and down relative to the fixed plate, the connecting rod will rotate accordingly, pushing the connecting block and the top column to move toward or away from the inner wall of the precast pile body, until the top column tightly contacts the inner wall of the precast pile body, forming a stable supporting structure, thereby enhancing the structural stability of the precast pile body.
[0011] Optionally, a screw is provided on the top wall of the movable plate at the axis position for vertical rotation, the top of the screw passes through the top wall of the precast pile body through threaded rotation, and the screw and the top wall of the precast pile body are matched through threaded rotation.
[0012] By adopting the above technical solution, the setting of the screw rod makes it easy to adjust the position of the movable plate. The movable plate can be driven to move up and down by rotating the screw rod, thereby adjusting the supporting strength of the top support assembly.
[0013] Optionally, an adjusting block for facilitating the rotation of the screw rod is provided at the top of the prefabricated pile body where the screw rod extends out.
[0014] By adopting the above technical solution, the setting of the adjustment block makes it convenient for operators to rotate and adjust the screw rod.
[0015] Optionally, a plurality of positioning holes are arranged around the top of the substrate in the through hole, each of the positioning holes is arranged to vertically penetrate the substrate, and a positioning pile is vertically penetrated in each of the positioning holes.
[0016] By adopting the above technical solution, the positioning piles play a key positioning role for the base plate, preventing the deviation of the overall structure, thereby greatly improving the stability and safety of the building foundation.
[0017] Optionally, a pressure plate is coaxially arranged on the top of the positioning pile, and the diameter of the pressure plate is larger than the diameter of the positioning pile. When the base plate is fixed on the foundation, the pressure plate is arranged to abut against the base plate.
[0018] By adopting the above technical solution, the pressure plate is hammered so that the multiple positioning piles can prevent the base plate from deflecting and fix the base plate on the foundation, thereby improving the stability of the base plate and further enhancing the stability of the entire preassembled pile structure.
[0019] Optionally, a level is provided on the top of the substrate.
[0020] By adopting the above technical solution, the level meter can detect and display the horizontality of the base plate in real time, ensuring that the base plate is always in a horizontal state during the installation of the precast pile body. This not only helps to ensure the verticality of the precast pile body, but also further improves the stability and safety of the entire building foundation.
[0021] Optionally, the spirit level is detachably mounted on a base plate, a seating groove is provided on the base plate corresponding to the spirit level, a limiting ring is coaxially arranged on the side wall of the seating groove near the top, a plug-in hole is provided on the limiting ring vertically connected to the seating groove, a plug-in block matching the plug-in hole is provided on the side wall of the spirit level, the plug-in block on the spirit level is aligned with the plug-in hole and inserted into the seating groove, and the spirit level is rotated, at which time the plug-in block is limited between the seating groove and the limiting ring.
[0022] By adopting the above technical solution, the spirit level is designed as a detachable structure, which helps to remove the pre-installed pile structure after it is fixed, and store and keep it so that it can be used on other pre-installed pile structures, thereby reducing construction costs; when in use, it is only necessary to align the plug-in block of the spirit level with the plug-in hole and insert it into the mounting groove, and rotate the spirit level to make it firmly limited between the mounting groove and the limit ring, so as to measure the instant levelness of the substrate for adaptive adjustment.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. During the installation of the precast pile, first place the base plate at the predetermined position and insert the positioning pile into the positioning hole to fix the base plate. Then, pass the precast pile through the through hole of the base plate, ensuring that the top of the bracket is aligned and inserted into the vertical groove on the outer wall of the precast pile. During the hammering construction process, the impact force of the heavy object on the top of the precast pile will drive the precast pile to move downward. At this time, the top of the bracket slides in the vertical groove, effectively limiting the deviation of the precast pile and ensuring its verticality;
[0025] 2. When the movable plate moves up and down relative to the fixed plate, the connecting rod will rotate accordingly, pushing the connecting block and the top column to move toward or away from the inner wall of the precast pile body. Until the top column tightly contacts the inner wall of the precast pile body, forming a stable supporting structure, thereby enhancing the structural stability of the precast pile body;
