Abstract
The utility model relates to a quick joint for a prestressed concrete pipe pile. The quick joint comprises a connector connected to an upper pipe pile connection end board. Anti-falling teeth are arranged on the circumference of the connector. The quick joint further comprises a joint box connected to a lower pipe pile connection end board in butt joint with the upper pipe pile connection end board. The joint box is embedded and fixed to a lower pipe pile and a through hole communicated with the joint box is formed in the lower pipe pile connection end board. A cylindrical sleeve divided into multiple sections is arranged in the joint box. The upper end and the lower end of the cylindrical sleeve are clamped in the space inside the joint box. The connector can be directly inserted through the through hole and expand the cylindrical sleeve. The inner surface of the cylinder sleeve is provided with teeth meshed with the anti-falling teeth on the connector. The outer face of the cylinder sleeve is further provided with a reset spring enabling the expanded cylindrical sleeve to be drawn to the center when the anti-falling teeth are meshed with the teeth. According to the quick joint for the prestressed concrete pipe pile, the structure is simple, the quick joint only can be inserted in one direction and can not move in the reverse direction, and connection is firm.
Description
[technical field]
The utility model relates to a kind of prestressed concrete pipe pile snap joint.
[background technology]
Existing in building operations, pile tube docking is all generally to weld by pile end board, and construction is complicated like this, and cost is high, and construction is slow, and joint quality is difficult to ensure.
[utility model content]
Problem to be solved in the utility model is to provide simple in structure, can only unidirectionally insert, and can not move a kind of prestressed concrete pipe pile snap joint being connected firmly in the other direction.
In order to solve the problem of above-mentioned existence, the utility model has adopted following technical proposal:
A kind of prestressed concrete pipe pile snap joint, snap joint comprises and is connected to the connector that pile tube is plugged on end plate, connector circumference is provided with anticreep tooth; Snap joint also comprises and is connected to the connector box that the lower pile tube that docks with upper pile tube is plugged on end plate, and connector box is by the lower pile tube box body that end plate inner side welding circle box forms of plugging into.Connector box is fixed on lower pile tube, and the lower pile tube end plate of plugging into is provided with the through hole being communicated with connector box; In connector box, be equipped with and be split into most cylindrical shrouds, cylindrical shroud upper and lower end is by clipping in the space in connector box, connector energy via through holes straight cutting enters and spreading cylindrical shroud, the tooth that cylindrical shroud inner surface has with on connector, anticreep tooth is meshed, cylindrical shroud outside is also equipped with and in the time that anticreep tooth and tooth match, is allowed the cylindrical shroud of spreading to the back-moving spring of center gathering.
Cylindrical shroud is split into 2 half, 4 half or 6 half.Pref. cylindrical cover is split into 4 half.Connector is one end of a cylindrical connecting rod, and the cylindrical connecting rod other end is threaded and is threaded with the upper pile tube end plate of plugging into.Cylindrical shroud length is not less than 3.5 centimetres, and after connector inserts in cylindrical shroud completely, the end in described connector box is pressed close in connector lower end.
Back-moving spring is jump ring, and jump ring has multiple, and multiple jump rings along cylindrical shroud up and down uniformly at intervals.
The beneficial effects of the utility model are:
1, snap joint has and is connected to the connector that pile tube is plugged on end plate, in the time that connector passes the cylindrical shroud of bottom plate, cylindrical shroud spreading, in the time that profile of tooth matches, connector is lived in cylindrical shroud interlock under the effect of jump ring, the present invention make the docking of two sections of pile tubes simple, plug into firmly, bearing capacity is high, with low cost, easy construction.
2, jump ring has multiplely, and multiple jump rings along cylindrical shroud up and down uniformly at intervals, make the cylindrical shroud of spreading draw in to center, draws strength in large, and docking firmly.
[brief description of the drawings]
Fig. 1 is the utility model syndeton schematic diagram between pile tube.
[detailed description of the invention]
As shown in Figure 1, a kind of prestressed concrete pipe pile snap joint, comprises and is connected to the connector 5 that pile tube is plugged on end plate, and is connected to the connector box 7 of plugging on end plate 4 on the lower pile tube 2 docking with upper pile tube.Connector 5 is one end of a cylindrical connecting rod, and the cylindrical connecting rod other end is threaded and is threaded with the end plate 3 of plugging on upper pile tube 1.Connector 5 circumference are provided with anticreep tooth; Connector box 7 is fixed on lower pile tube 2, the box body that connector box 7 is formed by the end plate 4 inner side welding circle boxes of plugging on lower pile tube.The lower pile tube end plate 4 of plugging into is provided with the through hole 41 being communicated with connector box; The cylindrical shroud 6 that is split into 4 half is housed in connector box, and cylindrical shroud 6 upper and lower ends cannot be moved axially in the space in connector box 7 by clipping.Connector 5 can enter and spreading cylindrical shroud 6 by via through holes 41 straight cuttings, cylindrical shroud 6 inner surfaces have the tooth being meshed with anticreep tooth on connector 5, and the jump ring 8 that allows the cylindrical shroud 6 of spreading draw in to center in the time that anticreep tooth and tooth match is also equipped with in cylindrical shroud 6 outsides.Jump ring 8 has multiple, and multiple jump rings 8 along cylindrical shroud 6 up and down uniformly at intervals.
Be connected firmly for ensureing, cylindrical shroud 6 length are not less than 3.5 centimetres.And connector 5 insert completely cylindrical shroud 6 interior after, in the time that anticreep tooth on connector 5 and cylindrical shroud 6 inner teeth gear profiles of tooth match, cylindrical shroud under the effect of jump ring tightly interlock live connector.The present invention make the docking of two sections of pile tubes simple, plug into firmly, bearing capacity is high, with low cost, easy construction.
