Description

Pile joint structure

The present invention provides a foundation pile butt joint structure, in particular a butt joint structure used in building structure construction methods and used to coaxially connect two foundation piles.

One of the construction foundation methods is to implant foundation piles under the ground where the building is to be built to bear the weight of the building and improve the stability of the building. The length of the foundation piles implanted in the ground will have different construction requirements depending on the geology and building design. For example, when the site strength is weak, longer foundation piles will be required to ensure safety.

Among them, for the convenience of transportation, the pre-cast foundation piles in the factory usually have fixed sizes and lengths. Therefore, in order to make the length of the foundation pile meet the construction requirements, two foundation piles are now coaxially connected to increase the length of the overall foundation pile setting. When the foundation pile connection operation is carried out, one foundation pile will be vertically planted in the ground first, and then the other foundation pile will be hung on it, so that the ends of the two foundation piles touch each other. The staff will spot weld around the ends of the foundation piles to fix the relative positions of the two foundation piles, and then completely weld around the ends of the foundation piles to make the two foundation piles coaxially connected.

However, since welding work is time-consuming, and the foundation piles located above are only suspended in the air, the foundation piles may sway with the wind or due to the movement of machinery, which requires workers to be particularly cautious when spot welding to avoid endangering their own safety, resulting in more time spent on work and lower work safety. When the weather is bad, wind and rain will make it difficult to carry out foundation pile docking work, which will delay the overall project. There is still room for improvement.

The main purpose of the present invention is to provide a foundation pile joint structure, in order to improve the current foundation pile joint operation, which is time-consuming and has low work safety by fixing the relative position of the foundation pile through spot welding.

To achieve the above-mentioned purpose, the foundation pile joint structure of the present invention is used to connect two foundation piles, and the foundation pile joint structure includes: two end plates, each of which is correspondingly arranged on one foundation pile, and each of which includes: a body, the body is in a plate shape, and the two opposite sides of the body are respectively defined as an assembly surface and a joint surface, and the body has an outer ring surrounding surface, and the assembly surface of the body is arranged at the end of the foundation pile; a plurality of assembly parts, the plurality of assembly parts are formed at intervals on the body body, and penetrates the assembly surface and the joint surface of the body; a plurality of joint grooves, the plurality of joint grooves are formed at intervals on the body, each of the joint grooves forms a circular opening on the outer circumferential surface of the body, and is recessed from the circular opening toward the inside of the body, and a rectangular communication opening is formed on the joint surface of the body, and the communication opening is connected to the circular opening; and at least one positioning hole, the at least one positioning hole is formed on the body, and is connected to the joint surface of the body and is recessed toward the inside of the body. The assembly surface of the body is concave; wherein the joint surfaces of the two end plates are in contact with each other, and the positions of the plurality of joint grooves of the two end plates correspond to each other, and the communication ports of the two joint grooves located at the corresponding positions are connected, so that the two joint grooves located at the corresponding positions form a joint portion, and the positions of the at least one positioning hole of the two end plates correspond to each other; a plurality of joint tenons, each of the joint tenons is arranged at the joint portion, and each of the joint tenons has two connected fixing columns, and the two fixing columns The two fixing posts are respectively extended into the two said joint grooves forming the said joint part, and the two fixing posts are respectively cylindrical, wherein the diameters of the two fixing posts of each said joint tenon are not equal, wherein the diameter of one said fixing post is equal to the diameter of the circular opening of the plurality of joint grooves, and the diameter of the other said fixing post is smaller than the diameter of the circular opening of the plurality of joint grooves; and at least one positioning member, the at least one positioning member is arranged in the at least one positioning hole corresponding to the position of the two end plates.

The foundation pile joint structure of the present invention is used to join the two foundation piles. The two end plates are respectively pre-set at the ends of the two foundation piles. When the foundation pile joint operation is performed, the positioning piece is placed in the positioning hole of the end plate of the foundation pile located below, and then the joint surfaces of the two end plates on the two foundation piles are brought into contact. The positioning piece is inserted into the positioning hole of the end plate of the foundation pile located above to preliminarily position the two foundation piles. The multiple joint grooves of the two end plates will be connected one-to-one to form multiple joint parts. The staff will then respectively set the multiple joint tenons on the multiple joint parts to fix the positions of the two foundation piles.

Therefore, by combining the two base piles through the base pile joint structure of the present invention, it is not necessary to fix the positions of the two base piles by spot welding, which can effectively improve the convenience of operation and shorten the operation time, and can also reduce the energy cost of machine operation and the energy cost consumed by spot welding. Furthermore, by matching the cylindrical fixing column of the multiple joint tenons with the circular opening of the joint part, the joint tenons can easily extend into the joint groove of the corresponding joint part, thereby making the base pile joint operation more convenient, and the joint groove is easier to process and shape, and the processing and manufacturing of the joint tenons is more convenient, so it can also reduce the processing cost and the energy consumed, which is in line with the environmental protection trend of energy saving and carbon reduction.

As shown in Figures 1 to 3, the body 11 of each end plate 10 is plate-shaped, and the two opposite surfaces of the body 11 are respectively defined as an assembly surface 111 and a joint surface 112, and the body 11 has an outer annular surrounding surface 113. The assembly surface 111 of the body 11 is set at the end of the foundation pile 40, and the plurality of assembly parts 12 are formed on the body 11 at intervals and penetrate the assembly surface 111 and the joint surface 112 of the body 11.

As shown in Figures 1 to 3, the plurality of joint grooves 13 are formed at intervals on the body 11. Each of the joint grooves 13 forms a circular opening 131 on the outer circumferential surface 113 of the body 11, and is recessed from the circular opening 131 toward the inside of the body 11. The outer contour of the circular opening 131 is intersecting with the joint surface 112 of the body 11. Each of the joint grooves 13 forms a rectangular connecting opening 132 on the joint surface 112 of the body 11, and the connecting opening 132 is connected to the circular opening 131. The at least one positioning hole 14 is formed on the body 11, and is connected to the joint surface 112 of the body 11 and recessed toward the assembly surface 111 of the body 11.

As shown in FIG. 3 and FIG. 4 , the joint surfaces 112 of the two end plates 10 are in contact with each other, and the positions of the plurality of joint grooves 13 of the two end plates 10 correspond to each other, and the connecting openings 132 of the two joint grooves 13 at the corresponding positions are connected, so that the two joint grooves 13 at the corresponding positions form a joint portion 15, and the positions of the at least one positioning hole 14 of the two end plates 10 correspond to each other.

As shown in Figures 4 and 5, each of the engaging tenons 20 is disposed on the engaging portion 15, and each of the engaging tenons 20 has two connected fixing columns 21, the two fixing columns 21 respectively extend into the two engaging grooves 13 forming the engaging portion 15, and the two fixing columns 21 are respectively cylindrical.

As shown in FIG. 3 , the at least one positioning member 30 is disposed at the at least one positioning hole 14 corresponding to the position of the two end plates 10 .

As shown in FIG. 3 , the foundation pile joint structure of the present invention is used to join the two foundation piles 40. Each of the end plates 10 is pre-installed at the end of one of the foundation piles 40 by the plurality of assembly parts 12 and the plurality of tie rods 41. As shown in FIG. 6 , when the foundation pile joint operation is performed, the positioning member 30 is placed in the positioning hole 14 of the end plate 10 of the foundation pile 40 located below, and then the joint surfaces 112 of the two end plates 10 on the two foundation piles 40 are aligned. The two foundation piles 40 are initially positioned by inserting the positioning member 30 into the positioning hole 14 of the end plate 10 of the foundation pile 40 located above. As shown in Figures 7 to 9, the multiple joint grooves 13 of the two end plates 10 are connected one-to-one to form multiple joint portions 15. The staff then respectively sets the multiple joint tenons 20 on the multiple joint portions 15 to fix the positions of the two foundation piles 40.

Therefore, by combining the two foundation piles 40 through the foundation pile docking structure of the present invention, it is not necessary to fix the positions of the two foundation piles 40 by spot welding, which can effectively improve the convenience of operation and shorten the operation time, and can also reduce the energy cost of machine operation and eliminate the energy cost consumed by spot welding.

In addition, as shown in FIG. 1 and FIG. 2 , on each of the end plates 10 , the plurality of joint grooves 13 are respectively located between the two adjacent assembly portions 12 in the end plate 10 , and only avoid the position where the at least one positioning hole 14 is formed on the end plate 10 . Thus, the two end plates 10 can form more joint portions 15 through a larger number of joint grooves 13 , and the plurality of joint tenons 20 are used to enhance the stability of the joint of the two end plates 10 .

In addition, the body 11 of each end plate 10 is annular, and the ratio between the length of each joint groove 13 and the length of the body 11 from the outer annular surface 113 to the inner annular surface of the body 11 is between 1:2 and 1:3. The length of the joint groove 13 is designed to provide sufficient bonding strength between the two end plates 10 while maintaining the structural strength of the end plates 10.

Furthermore, as shown in FIG. 4 , by cooperating with the circular opening 131 of the coupling groove 13 of the coupling portion 15 through the cylindrical fixing column 21 of the plurality of coupling tenons 20, the coupling tenons 20 can be easily inserted into the corresponding coupling groove 13 of the coupling portion 15, thereby making the foundation pile docking operation more convenient, and the coupling groove 13 is easier to process and shape, and the coupling tenons 20 only need to be formed by extrusion and cut into sections, without the need to time-consumingly turn the outer contour of the coupling tenons 20, so the processing and manufacturing of the coupling tenons 20 is more convenient, thereby reducing the processing cost and energy consumption, which is in line with the environmental protection trend of energy saving and carbon reduction.

As shown in FIG. 9 , the diameters R1 and R2 of the two fixing columns 21 of each of the joint tenons 20 are unequal. By designing the two fixing columns 21 of the joint tenons 20 to have unequal diameters R1 and R2, the worker can more easily pass the joint tenon 20 through the circular openings 131 of the two joint grooves 13 of the corresponding joint portion 15, thereby improving the convenience of combining the joint tenon 20 with the corresponding joint portion 15, thereby improving the convenience of operation.

Preferably, as shown in FIG8 and FIG9, the diameter R1 of one of the fixing columns 21 of the joint tenon 20 is equal to the diameter R3 of the circular opening 131 of the plurality of joint grooves 13, and the diameter R2 of the other fixing column 21 is smaller than the diameter R3 of the circular opening 131 of the plurality of joint grooves 13. Since the diameter R1 of the fixing column 21 of the joint tenon 20 is equal to the diameter R3 of the circular opening 131 of the plurality of joint grooves 13, the connection stability between the joint portions 15 corresponding to the joint tenon 20 can be improved, thereby improving the connection stability between the two end plates 10 and the connection stability between the two foundation piles 40 provided with the two end plates 10.

In addition, each of the joint grooves 13 is recessed from the circular opening 131 parallel to the joint surface 112 of the body 11 toward the inside of the body 11, so that the joint groove 13 is in the shape of a cylindrical groove. The design of the joint groove 13 in the shape of a cylindrical groove makes the processing and forming of the joint groove 13 more convenient, and improves the convenience of combining the joint tenon 20 with the corresponding joint portion 15.

In summary, the foundation pile joint structure of the present invention is used to combine the two foundation piles 40. The two foundation piles 40 can be initially positioned through the at least one positioning hole 14 and the at least one positioning member 30. Then, the plurality of joint tenons 20 are respectively arranged in the joint portion 15 formed by the plurality of joint grooves 13 of the two end plates 10 to fix the positions of the two foundation piles 40. Therefore, it is not necessary to fix the two foundation piles 40 through spot welding, which effectively improves the convenience of operation, shortens the operation time, and reduces the energy cost.
