Abstract

The utility model discloses a rapid joint of prestressed concrete pipe pile, including two end plates and connecting pins fixed and connected separately with the connecting ends of an upper pile and lower pile, and threaded holes are arranged in the end plate of the upper pile, one end of the connecting pins is provided with thread and can match with the threaded holes of the end plate of the upper pile, and the other end is square and the two sides of the other end have mesh teeth, a joint box is buried beneath the end plate of the lower pile, a pressure spring is arranged between the two ends of the joint box and the two pin plates, one end of the connecting pin with mesh teeth can be through the square hole in the end plate of the lower pile and can be inserted between the two pin plates, and the mesh teeth on the connecting pin can mutually mesh with the teeth on one end of the pin plate. The utility model enables two sections of pipe piles to butt easily and connect solidly, with high bearing capacity and low cost.

Description

Prestressed concrete pipe pile snap joint
Technical field
The utility model relates to a kind of prestressed concrete pipe pile snap joint.
Background technology
In building operations, often will be to the underground concrete tubular pile of burying underground, and common concrete tubular pile be prefabricated after, at the scene by the method for the welding upper and lower two sections pile tubes of plugging into, this structure makes speed of application slow, the high and difficult quality guarantee of plugging into of cost.Some patent applications about the snap joint of concrete soil pipe pile tube are also arranged at present, and as Chinese patent ZL00227092.7, but its structure is complicated, and cost is relatively also than higher, and the intensity after plugging into also has much room for improvement.
Summary of the invention
The purpose of this utility model be for provide a kind of simple in structure, cost is low and the snap joint of the measured prestressed concrete pipe pile of matter of plugging into.
Main technical schemes of the present utility model is: this concrete snap joint comprises respectively with last, following stake is plugged into and is held two affixed end plates, connecting pin, offer screwed hole in the end plate of last stake, connecting pin one end is threaded and can cooperates with the screwed hole of last stake end plate, the other end is square, and both sides have engaging tooth, the end plate below of following stake is embedded with connector box, between two ends of connector box and two pin plates compression spring is housed, the square hole that one end of connecting pin band engaging tooth can pass down on the end plate of stake inserts between two pin plates, and the engaging tooth on it can be meshing with each other with the tooth of pin plate one side.
When plugging into upper and lower two sections pile tubes, earlier the threaded end of connecting pin is screwed in the screwed hole of going up on the stake end plate, sling then and go up stake, square hole on the following end plate of one end correspondence of connecting pin band engaging tooth is inserted, be inserted between two pin plates in the connecting box always, the engaging tooth of connecting pin and the tooth on the pin plate are under the compression spring effect, and tight engagement is plugged into together upper and lower pile tube securely.The utility model structure is simpler, and cost is lower, and plug into firmly, bearing capacity is high, flexural strength is high.
Description of drawings
The utility model is described in further detail below in conjunction with specific embodiments and the drawings:
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the big enlarged drawing of the office of Fig. 1;
Fig. 3 is following a vertical view.
The specific embodiment
As Fig. 1, shown in Figure 2, present embodiment comprises respectively with last, following stake 1,2 plug into holds two affixed end plates 3,3 ', connecting pin 5, offer screwed hole 31 in the end plate 3 of last stake 1, connecting pin 5 one ends are threaded 51 and can cooperate with the screwed hole 31 of last stake end plate, the other end is square, and both sides have engaging tooth 52, end plate 3 ' the below of following stake 2 is embedded with connector box 7, between two ends of connector box 7 and two pin plates 4 compression spring 6 is housed, one end of connecting pin 5 band engaging tooths can pass down between two pin plates 4 of square hole 31 ' insertion on the end plate 3 ' of stake, and the engaging tooth 52 on it can be meshing with each other with the tooth of pin plate one side.As shown in Figure 3, evenly be furnished with 6 square holes 31 ' on the following end plate 3 ' of present embodiment, its below is corresponding to be equipped with 6 connector boxs 7, and upward also has 6 screwed holes 31 corresponding with square hole 31 ' on the stake end plate 3.All there is connecting pin to connect between each connector box and the screwed hole.
