Description

Ground pile structure

The invention relates to the pillar structure of buildings, in particular to a ground pile structure.

Ground piles are used in many construction methods of building or water and soil conservation. The current ground piles can be divided into two types, one is the straight column type and the other is the spiral type. The so-called straight column style is that the body of the ground pile is like a straight column, straight up and down. From the perspective of the straight column type, its biggest advantage is that it is easy to insert into the ground, but because of its poor pull-out resistance, it is necessary to increase its insertion depth to improve stability. The spiral type is to set outwardly protruding threads on the outer periphery of the straight column type, and insert the ground pile into the ground in a spiral manner. Although increasing the setting of the thread can improve the pull-out resistance of the ground pile, the effect is still It is very limited, and it is easy to loosen due to factors such as earthquakes or strong winds, causing the ground piles to fall.

Furthermore, in order to allow the ground pile to be smoothly rotated and inserted into the ground, the outer diameter of the ground pile is slightly tapered, that is, the outer diameter of the tapered head end is the smallest and then gradually expands to a certain size. Although this form can be used for the insertion of ground piles, it has the problem of being top-heavy, so the ground piles must be very long, and the part inserted into the ground must be inserted very deep to increase its stability.

The main purpose of the present invention is to provide a ground pile structure with simple structure, easy installation and strong pull-out resistance.

In order to achieve the above-mentioned main purpose, the ground pile structure of the present invention includes: a cylinder, which is hollow tubular, has an opening at one end, and an insertion portion at the other end, and at least one insertion port is provided on the surface of the cylinder to communicate with the column. The internal and external space of the body, a guide piece is provided at the corresponding insertion opening in the cylinder, and the guide piece has a guide groove, and each guide piece bends and extends from the insertion opening toward the opening direction of the cylinder body. Corresponding to each socket is provided with a contact piece. An inner sleeve is arranged in the cylinder, and the inner sleeve has an elongated body and an end with an outer diameter larger than the elongated body. An inserter is arranged in the cylinder and is correspondingly sandwiched between the elongated body of the inner sleeve and a supporting piece.

Preferably, the insertion port is U-shaped or V-shaped.

Preferably, one end of the guide groove is in the shape of a flat plate and gradually bends towards the other end of the guide member, so that the shape of the guide groove at the end of the guide member connected to the insertion port corresponds to the insertion port.

Preferably, the insert is in the shape of a strip, and is arranged in the cylinder and sandwiched between the elongated body of the inner sleeve and the corresponding abutment.

Please refer to Figures 1 to 6, the ground pile structure of the first embodiment of the present invention includes:

A cylinder 10 is hollow tubular, with an opening 11 at one end and a tapered insertion portion 12 at the other end. The shape of the cylinder 10 is not limited to circular, rectangular or triangular. In this embodiment, a circle is used as an illustration example, but it is not limited thereto. The surface of the cylinder 10 is provided with a plurality of insertion openings 13 , which communicate with the inner and outer spaces of the cylinder 10 . The insertion openings 13 can be U-shaped or V-shaped. In this embodiment, a U-shape is taken as an example for illustration, and the U-shaped insertion openings can face upward or downward. In this embodiment, the cylinder 10 is provided with three insertion ports 13, but it is not limited thereto, and multiple insertion ports may also be provided. The insertion openings 13 can be directly disposed on the column body 10 or firstly disposed on a cover sheet and then disposed on the column body 10 as shown in FIG. 2 . A guide piece 14 is provided on the inner wall of the cylinder 10 corresponding to each insertion opening 13 . The guide piece 14 has a guide groove 142, one end of the guide groove 142 is in the form of a flat plate and gradually bends toward the other end to form a U-shape, so that the guide piece 14 is connected to the insertion port 13 at its end. The shape of the guide groove 142 corresponds to that of the insertion port 13 and the guide member 14 has a notch 141 at the end thereof. Each guide piece 14 bends and extends from the insertion opening 13 toward the opening 11 of the cylinder, and makes the plate-shaped end of the guiding groove 142 away from the insertion opening 13 .

The column body 10 is provided with a plurality of contact pieces 15 , and each contact piece 15 is set corresponding to an insertion port 13 . The supporting pieces 15 can be independently arranged in the column body 10 or as in this embodiment, the supporting pieces 15 can be formed by bending a plate, and each supporting piece 15 corresponds to the insertion port of the column body 10 There is a gap 16 at 13 places.

An inner sleeve 20 is disposed in the column body 10 . The inner sleeve 20 has an elongated body 21 and an end portion 22 with an outer diameter larger than the elongated body 21 . In this embodiment, the inner sleeve 20 is a round tube, but not limited thereto. The notch of the guide can be matched with the elongated body of the inner sleeve correspondingly, so that the fit between the guide and the elongated body is better.

A plurality of inserts 30 are respectively provided corresponding to a supporting piece 15 , and each inserting piece 30 is in the shape of a strip, and is arranged in the cylinder 10 and sandwiched between the elongated body 21 of the inner sleeve and the corresponding supporting piece 15 . One end of each insert 30 abuts against the bottom surface of the inner sleeve end 22 or one end of each insert 30 can be directly welded and fixed to the end 22 .

With the structure of the present invention, when installing and using, the cylinder 10 is first inserted into the ground, and then the inner sleeve 20 is pressed down, as shown in Fig. 1 and Fig. 5 to Fig. 6 . Utilize the end portion 22 of this inner sleeve to push down these inserters 30 and move downward, and push down along with this inner sleeve end 33 and can make these inserters 30 also move downward, the inserter 30 One end will enter the guide groove 142 and be guided and limited by the space of the guide groove 142, so that the inserts 30 are bent and deformed while moving downwards, so that they can be bent into a U shape and The cylinder 10 protrudes outward from the insertion openings 13 .

Since one end of the guide grooves 142 is flat and gradually changes toward the other end, the inserts 30 can also be squeezed and deformed when passing through the guide groove 142 and passing through the insertion port 13, forming The same U-shape as the insertion port 13 is used to increase pull-out resistance and bearing capacity. The function of setting the inner sleeve 20 and the counter pieces 15 is to sandwich the inserter 30 with the elongated body 21 of the inner sleeve and the counter piece 15, so as to prevent the inserters 30 from being squeezed. The inside of the column body 10 is bent and deformed, so that the inserter 30 cannot smoothly protrude from the insertion ports 13 .

In this way, the present invention can utilize the structure of the inserts 30 protruding from the column 10 to form a state extending outward like a tree root, so as to increase the pull-out resistance and bearing capacity of the column 10 and increase the column 10 stability, to improve the shortcomings of the old ground piles, and to achieve the purpose of the invention with low cost, simple structure but clear effect.

As shown in Figure 7, it is the second embodiment of the present invention. In this embodiment, the ground pile structure includes:
