Abstract

The utility model provides an end plate of a prestressed concrete hollow square pile. The end plate comprises a square steel plate, a circular hole is arranged at the center of the square steel plate, concave holes are stamped around the circular hole, the number of the concave holes is identical to that of main reinforcements of the square pile, the concave holes of the square steel plate are protruded out of the bottom of the square steel plate and include tensioning steel bar fixing counter bored holes and tensioning steel bar bolt anchoring holes. The thickness of the end plate is reduced by about a half of that of a common end plate of a prestressed concrete hollow square pile under the condition that tensioning steel bar anchoring bolts are identically stressed, consumption of steel materials is greatly saved, large-scale production of pile end plates is facilitated by the aid of a stamping forming mode, production efficiency of the end plates is improved, and automatic production is guaranteed.

Description

A kind of pre-stressed concrete hollow square stake end plate
Technical field
The utility model relates to employed preformed pile end plate in a kind of building trade, is specifically related to a kind of pre-stressed concrete hollow square stake end plate.
Background technology
The pre-stressed concrete hollow square pile end plate is mounted in the parts at pre-stressed concrete hollow square stake two ends; Be mainly used in the anchoring of prestressed stretch-draw rod iron in the hollow square pile production and the pile extension in the construction; Its agent structure is a square plate, is furnished with the stretch-draw rod iron location counterbore consistent with hollow square pile master muscle number on the steel plate face.In the process of making the pre-stressed concrete hollow square stake, reinforcing cage master concrete steel rod is passed square pile end plate and is fixed in the counterbore of stretch-draw rod iron location, the turnbuckle through stretch-draw bolt anchoring hole comes the stretch-draw rod iron, applies prestressing force to rod iron.End plate bears pressure when steel bar tensing, the time bear roof pressure power in piling, so in order to guarantee certain intensity requirements, used pre-stressed concrete hollow square stake end plate thickness is generally between 18~22mm, and whole end plate thickness is even, it is more to consume steel.
Traditional end plate moulding process generally adopts cast molding or forging forming; It is unstable relatively that honeycomb, bubble, quality appear in the end plate of simple cast molding easily; The phenomenon of easy drawing crack or slight distortion, bending when stretch-draw; The stake end can't be vertical during the construction butt joint, and end plate is prone to broken during the hammering construction; The machining accuracy of forging forming is lower, and cost of equipment is higher, and operation is loaded down with trivial details relatively, is not easy to realize in enormous quantities, the automated production of end plate.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art; Provide a kind of under the stressed identical situation of stretch-draw rod iron anchor bolt; End plate thickness can reduce about half, can practice thrift the steel consumption widely, and processes simple pre-stressed concrete hollow square stake end plate.
A kind of pre-stressed concrete hollow square stake end plate; Comprise square plate; The centre of said square plate offers circular hole; Said circular punching press has the shrinkage pool that protrudes square plate with the consistent bottom surface of the main muscle number of side stake, and fixedly counterbore and stretch-draw rod iron bolt anchoring hole constitute said shrinkage pool by the stretch-draw rod iron.
Preferably, said stretch-draw rod iron bolt anchoring hole employing fine thread.
Preferably, the material of said square plate is the Q235b steel.
The utility model is under the stressed identical situation of stretch-draw rod iron anchor bolt, and comparable common pre-stressed concrete hollow square stake end plate thickness reduces about half, practices thrift the steel consumption widely; And help realizing the production in enormous quantities of pile end plate through punch forming, improved the production efficiency of end plate, for automated production provides assurance.

Fig. 1 is the structural representation of the utility model.
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is further specified.Should be understood that following examples only are used to the utility model is described but not the scope that is used to limit the utility model.
Referring to Fig. 1 and Fig. 2; A kind of pre-stressed concrete hollow square stake end plate that the utility model provides; Comprise square plate 1, the centre of said square plate 1 offers circular hole 2, and punching press has consistent with side's main muscle number of stake around the said circular hole 2; The shrinkage pool 3 of bottom surface protrusion square plate 1, fixedly counterbore 4 and stretch-draw rod iron bolt anchoring hole 5 constitute said shrinkage pool 3 by the stretch-draw rod iron.
Preferably, fine threads are adopted in said stretch-draw rod iron bolt anchoring hole 5.
Preferably, the material of said square plate is the Q235b steel.
