Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a building pile for building construction. Background Art

[0002] Building piles are columnar bearing members that penetrate deep into the soil layer and are the main components of building pile foundations. The bearing capacity of building piles in the soil mainly comes from the side resistance and end resistance of the soil. According to the type of bearing capacity that building piles are subjected to in the soil, they can be divided into friction piles, end-bearing piles, end-bearing friction piles, and friction end-bearing piles. In reality, due to different soil conditions, building piles driven into different soils are subject to different side resistance and end resistance of the soil. In some areas with relatively loose soil, after the building piles are driven into the soil layer, the soil on the side and end of the piles may not be able to provide effective support for the pile body, affecting the structural safety of the building piles.

[0003] Publication No. CN105862726A discloses a construction pile with side piles. By setting side piles in the construction pile, when the construction pile is driven into the soil, the column slides downward, driving the left and right columns to squeeze the inclined connecting plate, so that the connecting plate pushes the side piles into the soil, thereby increasing the horizontal fit of the construction pile, enhancing the load-bearing capacity, and making the construction pile more stable. However, the contact surface between the connecting plate and the left and right columns is inclined. Due to factors such as pile foundation settlement, the force generated by the external soil on the side piles will push the connecting plate to retract into the pile body, causing the left and right columns to slide upward and the side piles to retract into the pile body, thereby causing the side piles to lose their stabilizing effect on the construction pile.

[0004] Therefore, it is necessary to propose a building pile for construction to solve the technical problems existing in existing building piles. Utility Model Content

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a building pile for construction in this embodiment includes a pipe pile body 1, a pile tip assembly 2 and a connecting flange ring 3, the pile tip assembly 2 is fixedly arranged at the lower end of the pipe pile body 1, and the connecting flange ring 3 is fixedly arranged at the upper end of the pipe pile body 1.

[0034] The pile tip assembly 2 includes a pile tip connecting plate 21, a pile tip main body 22 and a main rotating shaft 23.

A bottom cross rotating pattern 2121 is opened at the center of the upper end surface of the rotating bottom shaft 212. The upper end of the main rotating shaft 23 is fixedly arranged in the lower wall of the rotating bottom shaft 212. The main rotating shaft 23 is fixed with a main bevel gear 231 on the upper side wall, and a gear rotating shaft 213 is fixed with a ring array at the lower edge of the rotating hole 211. A slave bevel gear 232 is rotatably provided on the gear rotating shaft 213. The slave bevel gears 232 are respectively meshed with the main bevel gear 231. A control screw rod 233 is fixed at the end center of the slave bevel gear 232. The control screw rod 233 is inclined from the center of the pile tip body 22 to the edge of the pile tip body 22, and the ends of the control screw rod 233 are respectively rotatably provided on the inner wall of the pile tip body 22;

[0035] The side walls of the control screw rod 233 are respectively sleeved with sliding blocks 234, and the sliding blocks 234 are respectively threadedly connected to the control screw rod 233. The side walls of the sliding blocks 234 are respectively fixed with side tie rods 235, and the side tie rods 235 are arranged parallel to the control screw rod 233. The side tie rods 235 are made of high-strength steel.

[0036] The side wall of the pile tip body 22 is provided with an annular array of extension holes 221 , and the side tie rods 235 are movably arranged to penetrate the extension holes 221 . When the sliding block 234 is located at the upper end of the control screw rod 233 , the lower end of the side tie rod 235 is flush with the outer wall of the pile tip body 22 .

[0037] A clamping groove 31 is symmetrically provided on the inner edge of the upper wall of the connecting flange ring 3, a connecting plate 32 is clamped in the center of the connecting flange ring 3, and clamping blocks 321 are symmetrically fixed on the side walls of the connecting plate 32, and the clamping blocks 321 are respectively clamped in the clamping groove 31;

[0038] A rotating top shaft 33 is rotatably provided through the center of the connecting disk 32, a top cross rotation pattern 331 is provided at the center of the upper wall of the rotating top shaft 33, a control rod 34 is fixedly provided at the center of the lower wall of the rotating top shaft 33, a cross rotating head 341 is provided at the lower end of the control rod 34, and the cross rotating head 341 is engaged in the bottom cross rotation pattern 2121.

[0039] Working principle and working process: the construction personnel connect the device with a pile driver (existing technology, which will not be described in detail here), and use the pile driver to tamp the pipe pile body 1 and the pile tip assembly 2 into the soil layer until the pile tip assembly 2 is tamped into the specified depth. At this time, the construction personnel remove the pile hammer and the pile frame. A top cross groove 331 is opened at the center of the upper wall of the rotating top shaft 33, and a rod matching the top cross groove 331 can be inserted into the top cross groove 331. The construction personnel rotate the rod manually or by rotating equipment (such as a rotating motor), thereby driving the rotating top shaft 33 to rotate, and the rotating top shaft 33 drives the control rod 34 to rotate. The cross rotating head 341 at the lower end of the control rod 34 is engaged with the bottom cross groove 2121 on the rotating bottom shaft 212, so that the rotating bottom shaft 212 will rotate under the drive of the cross rotating head 341, thereby driving the main rotating shaft 23 to rotate;

[0040] The main rotating shaft 23 can drive the main bevel gear 231 to rotate synchronously, and the main bevel gear 231 drives the surrounding multiple bevel gears 232 to rotate, so that the multiple control screws 233 rotate synchronously, so that the sliding block 234 moves from the upper end of the control screw 233 to the lower end, and the side tie rod 235 extends from the extension hole 221 and wedges into the soil, thereby increasing the tie strength between the pile tip body 22 and the soil at the end of the building pile, thereby increasing the end resistance of the building pile, and effectively improving the stability of the building pile;

[0041] The sliding block 234 is connected to the control screw rod 233 by threads, and the threaded structure can effectively lock the side tie rod 235 and the control screw rod 233 to ensure that when the external soil pushes the side tie rod 235, the side tie rod 235 will not retract into the pile tip body 22 and cause the reinforcement effect to be lost.

[0042] The connecting plate 32 is movably connected to the connecting flange ring 3. After completing the extension operation of the side tie rod 235, the construction personnel can remove the connecting plate 32 from the connecting flange ring 3, so as to take out the control rod 34 from the pipe pile body 1, which is convenient for subsequent construction. If you want to increase the overall length of the building pile, after tamping one pipe pile body 1 into a specified depth, you can connect another pipe pile body 1 (the lower end of the pipe pile body 1 does not have a pile tip assembly 2, but a connecting flange ring 3 is fixed at the bottom) to the pipe pile body 1 tamped into the soil layer through the connecting flange ring 3. The specific method is to use traditional welding. At this time, the upper pipe pile The cross rotating head 341 at the lower end of the control rod 34 inside the body 1 cooperates with the top cross turning pattern 331 at the upper end of the lower pipe pile body 1. The construction personnel continue to tamp the connected pipe pile body 1 into the soil layer through the pile driver. After the pile tip assembly 2 at the lower end reaches the specified depth, the construction personnel use the same method to rotate the uppermost rotating top shaft 33. The upper rotating top shaft 33 drives the lower rotating top shaft 33 and the control rod 34 to rotate through the control rod 34, so that the lowermost rotating bottom shaft 212 rotates and drives the side tie rod 235 to extend, thereby achieving the technical effect of adjusting the overall length of the building pile.

[0043] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0044] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
