Description

Technical Field

[0001] The present application relates to the technical field of building pile structures, and more specifically, to prestressed concrete floor piles. Background Art

[0002] Floor piles are foundation piles below the natural floor. Floor piles are also called column piles. They are single or multiple piles perpendicular to the ground, usually made of concrete or steel. Floor piles are mainly used to support the floor, platform or base of a building or structure and transfer the load to the underground soil. They can provide stable foundation support and bear the heavy load of the building.

[0003] In the prior art, the connection process between the floor pile and the structural floor is as follows: first, holes for steel bars or threaded steel pipes are reserved in the structural floor. The positions of the holes should be determined according to the layout of the floor piles. The floor piles are inserted into the holes so that they fit tightly with the structural floor. Then, holes are drilled at the tops of the floor piles, and the threaded steel pipes are inserted therein. The floor piles and the structural floor are fastened by tightening the nuts. However, the floor piles inserted into the ground are prone to shear damage during subsequent drilling, and the connection surface between the floor cap and the cap is prone to tilt. In view of this, we propose prestressed concrete floor piles. Utility Model Content

[0004] Technical issues to be solved

[0005] The purpose of this application is to provide a prestressed concrete floor pile to solve the problems raised in the above background technology.

[0010] As an optional solution of the technical solution of the present application document, the engaging and limiting structure includes a positioning groove opened in the middle of the top end of the bolt pile.

[0011] As an optional solution of the technical solution of the present application document, the limiting structure also includes a slot, a slot is opened in the middle of the drill rod, a through hole is opened at the bottom of the slot, and the through hole and the positioning groove are in the same straight line.

[0012] As an optional solution of the technical solution of the present application document, the limiting structure also includes a limiting groove, and a plurality of limiting grooves are evenly opened on the drill rod, and the limiting grooves are symmetrically arranged around the periphery of the slot.

[0013] As an optional solution to the technical solution of the present application document, a positioning top block is fixedly connected to the middle of the bottom end of the base structure, and the positioning top block is configured as a convex shape.

[0015] Beneficial Effects

[0016] Compared with the prior art, the advantages of this application are:

[0017] The present application sets up multiple locking and limiting structures. After the floor pile is inserted into the soil, the cap structure is placed above the drill rod and the cap structure is rotated at a certain angle to achieve multi-level locking and limiting between the drill rod and the cap structure. This can ensure a stable connection between the floor pile and the cap structure without performing subsequent drilling on the bolted ground pile, thereby improving the shear resistance of the floor. The locking and fixing between the drill rod and the cap structure also makes the cap structure horizontal and will not tilt, thereby effectively preventing the floor from settling, displacement and deformation.

[0022] See also Figure 1-3 ,This application provides a technical solution:

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a drill rod 2 is fixedly connected to the top of the bolt pile 1, and the drill rod 2 is engaged with a screw machine, and the screw machine drives the drill rod 2 and the bolt pile 1 to rotate, thereby inserting the bolt pile 1 into the ground soil.

[0024] refer to Figure 2 A positioning groove 11 is provided in the middle of the bolt pile 1, a slot 22 is provided in the middle of the drill rod 2, and a through hole is provided at the bottom of the slot 22. The through hole and the positioning groove 11 are in the same straight line, and the two are equal in size. Figure 1 As shown, the top end of the drill rod 2 is connected with a support structure 3, as shown in FIG. Figure 3 As shown, a positioning top block 32 is fixedly connected to the middle part of the bottom end of the base structure 3, and the positioning top block 32 is fixedly set as a convex block. The size of the bottom end of the positioning top block 32 is equal to the size of the through hole and the positioning groove 11, and the positioning top block 32 can be inserted into the through hole and the positioning groove 11, so that the base structure 3 and the middle part of the drill rod 2 and the bolt pile 1 can be engaged and limited. The size of the upper end of the positioning top block 32 is equal to the inner size of the slot 22, and the positioning top block 32 can be inserted into the slot 22, further increasing the degree of engagement and limitation between the base structure 3 and the middle part of the drill rod 2 and the bolt pile 1.

[0025] refer to Figure 3 A plurality of limit grooves 23 are evenly arranged around the slot 22, and the plurality of limit grooves 23 are symmetrically arranged around the slot 22. A limit block 33 is arranged inside the limit groove 23, and the other ends of the plurality of limit blocks 33 are fixedly connected to the base structure 3. The plurality of limit blocks 33 are symmetrically fixed to the periphery of the positioning top block 32, so that the base structure 3 can be engaged with and limited by the periphery of the drill rod 2 and the bolt pile 1. When the staff rotates the base structure 3, the rotation of the base structure 3 will drive the plurality of fixedly connected limit blocks 33 to rotate synchronously. When the limit block 33 moves to the top of the limit groove 23, the limit block 33 can slide into the inside of the limit groove 23.

[0026] refer to Figure 1 and Figure 3 A supporting platform 31 is fixedly connected to the periphery of the supporting platform structure 3. The inner size of the supporting platform 31 is equal to the outer size of the drill rod 2. The inner side of the supporting platform 31 is engaged with the outer side of the drill rod 2. The inner side of the supporting platform 31 is provided with a wavy texture, which increases the friction between the supporting platform 31 and the drill rod 2.

[0027] When carrying out the floor hardening project, the staff first rotates the drill rod 2, and the rotation of the drill rod 2 drives the bolt pile 1 to rotate. The bolt pile 1 rotates and is inserted into the soil and is directly used as a pile body. Then the cap structure 3 is placed above the drill rod 2, and the positioning top block 32 in the middle of the bottom end of the cap structure 3 is inserted into the positioning groove 11 inside the bolt pile 1 and the slot 22 in the middle of the drill rod 2. The bottom end of the positioning top block 32 passes through the through hole and is inserted into the positioning groove 11, so that the bolt pile 1 and the drill rod 2 are limited and fixed by the positioning top block 32. At the same time, the upper part of the positioning top block 32 is engaged with the slot 22. Then the cap structure 3 is rotated to limit the multiple limit positions at the bottom end of the cap structure 3. The block 33 is adjusted in position until the limit block 33 is engaged with the limit groove 23 on the outside of the slot 22, and the multiple limit blocks 33 at the bottom end of the base structure 3 are inserted into the inner side of the limit groove 23 to improve the tightness of the connection between the base structure 3 and the drill rod 2. At this time, the supporting base 31 at the bottom end of the base structure 3 is engaged with the outside of the drill rod 2. The base structure 3 is stably placed on the top of the drill rod 2 under the action of three groups of engaging limit structures, and there is no need to carry out subsequent construction of the bolt piles 1 inserted into the soil. The concrete paving operation can be carried out, and the remaining building structures that need to be installed can also be directly inserted into the base structure 3 to carry out concrete pouring, thereby improving the stability of the building on the floor.
