Technical field
The invention belongs to concrete precast pile technical fields, are specifically related to a kind of reinforcing bar in concrete precast pile
Framework cage.
Background technique
Concrete precast pile refers to using a kind of prefabricated structure of elongate concrete made of first prestressing force and centrifugal casting
Part.For the performance for improving prefabricated pile, steel reinforcement framework cage is provided in such stake, traditional steel reinforcement framework cage is by main reinforcement and stirrup
It constitutes, main reinforcement includes several deformed bar and glass fiber-reinforced polymer along prefabricated pile length direction arrangement, and the stirrup is used for
Deformed bar and glass fiber-reinforced polymer is interval-staggered in the same cylinder side face using prefabricated pile center line as axis,
Middle deformed bar and stirrup weld, and the glass fiber-reinforced polymer and stirrup are fixed by way of binding, the connection type
There are the drawbacks of: in concrete prefabricated forming pile and use process, glass fiber-reinforced polymer and stirrup binding this connection side
Formula is not extremely firm, is easy to loose, glass fiber-reinforced polymer is caused to shift, so that the mechanical performance of entire concrete precast pile is influenced,
Such as tensile property, shock resistance.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of steel reinforcement framework cages in concrete precast pile, should
Framework of steel reinforcement basket structure is more stable securely, ensure that the tensile strength and shock resistance of concrete precast pile.
In order to achieve the object of the present invention, the invention adopts the following technical scheme:
A kind of steel reinforcement framework cage in concrete precast pile, including stirrup, along the prefabricated pile length direction arrange
Deformed bar and glass fiber-reinforced polymer, the deformed bar interval is welded in the circumferential direction of the stirrup and constitutes cage body,
It is characterized by: being arranged with positioning disk in the cage body, the positioning disk is equipped with the positioning passed through for the glass fiber-reinforced polymer
Hole.
Further technical solution, the disk of the positioning disk is vertical with the prefabricated pile length direction, the positioning disk
Edge be equipped with notch, the notch constitutes the bayonet engaged with the deformed bar.
Further technical solution, the quantity of the glass fiber-reinforced polymer are equal to or less than the quantity of deformed bar；Work as glass
When the quantity of glass fiber bar is equal to the quantity of deformed bar, glass fiber-reinforced polymer and deformed bar are circumferentially spaced staggeredly
Arrangement；When the quantity of glass fiber-reinforced polymer is less than the quantity of deformed bar, glass fiber-reinforced polymer is dispersed between deformed bar.
Further technical solution, the positioning disk have multiple along the prefabricated pile length direction arranged for interval.
Further technical solution, the positioning disk are made of plastic material.
Further technical solution, the stirrup are tie hoop.
The beneficial effects of the present invention are:
(1) positioning disk of the present invention is stuck in cage body, and secondly the glass fiber-reinforced polymer is pacified after passing through location hole by positioning
In the cage body, which makes the installation of concrete precast pile glass fiber-reinforced polymer in production or use process
Position keeps stablizing and fix reliably, i.e., framework of steel reinforcement basket structure of the present invention is more firm, greatly ensure that concrete prefabricated
The tensile strength and shock resistance of stake.
(2) positioning disk of the present invention is fixed by bayonet and deformed bar realization, the positioning disk
Fixed form is simple, and effectively prevents positioning disk in the intracorporal rotation of cage, further ensures glass fiber-reinforced polymer installation site
Reliability.
(3) deformed bar in invention and glass fiber-reinforced polymer are worked in coordination the mode of installation, so that concrete precast pile
Vertical bearing capacity, resistance to impact, tensile strength, corrosion resistance, shock resistance and it is light-weight the advantages that all perform to it is ultimate attainment, because
This steel reinforcement framework cage of the present invention can significantly improve concrete precast pile characteristic, it might even be possible to meet compared with high anti-seismic area to pile foundation
Performance requirement.
(4) in order to further ensure the location and installation requirement of the glass fiber-reinforced polymer, the present invention is along the prefabricated pile length
Direction arranged for interval has multiple positioning disks, and multiple positioning disks are used in combination, and the glass fiber-reinforced polymer is more consolidated
Ground is installed in cage body.
(5) positioning disk that is made of plastic material of the present invention is easy to manufacture and low in cost, at the same be easily installed and
Disassembly, practicability are extremely strong.

Specific embodiment
More specific detail is made to technical solution of the present invention below with reference to embodiment:
As shown in Figure 1, the present invention include stirrup 11, along 10 length direction of prefabricated pile arrangement deformed bar 12 with
And glass fiber-reinforced polymer 13, the interval of deformed bar 12, which is welded in the circumferential direction of the stirrup 11, constitutes cage body, the cage body
It is inside arranged with positioning disk 14, the positioning disk 14 is equipped with the location hole 141 passed through for the glass fiber-reinforced polymer 13.Institute of the present invention
It states positioning disk 14 to be stuck in cage body, next described glass fiber-reinforced polymer 13 is after location hole 141 by location and installation in the cage body
Interior, which keep the installation site of the glass fiber-reinforced polymer 13 in production or use process of concrete precast pile 10
Stablize and fixed reliable, i.e., framework of steel reinforcement basket structure of the present invention is more firm, greatly ensure that the anti-of concrete precast pile 10
Tensile strength and shock resistance.
The disk of the positioning disk 14 is vertical with 10 length direction of prefabricated pile, and the edge of the positioning disk 14, which is equipped with, to be lacked
Mouth 142, the notch 142 constitute the bayonet engaged with the deformed bar 12.Positioning disk 14 of the present invention passes through bayonet
It is fixed with the deformed bar 12 realization, the fixed form of the positioning disk 14 is simple, and effectively prevents positioning disk
14, in the intracorporal rotation of cage, further ensure the reliability of 13 installation site of glass fiber-reinforced polymer.
The quantity of the glass fiber-reinforced polymer 13 is equal to or less than the quantity of deformed bar 12；When the number of glass fiber-reinforced polymer 13
When amount is equal to the quantity of deformed bar 12, glass fiber-reinforced polymer 13 and deformed bar 12 is circumferentially spaced is staggered；
When the quantity of glass fiber-reinforced polymer 13 be less than deformed bar 12 quantity when, glass fiber-reinforced polymer 13 be dispersed in deformed bar 12 it
Between.Deformed bar 12 and glass fiber-reinforced polymer 13 in invention are worked in coordination the mode of installation, so that concrete precast pile 10
