Description
The application is " tension nut sunk type prefabricated pile (application number：201510313980.5；The applying date：
2015.06.09) " divisional application.
Technical field
The invention belongs to building trade prefabricated component technical field, is related to a kind of prefabricated pile, more particularly to a kind of tension nut
Sunk type prefabricated pile.
Background technology
Because the quality stability of driven cast-in-place pile is relatively poor, in recent years, precast prestressed concrete stake obtains swift and violent
Development., be according to the different stakes for needing to select different length during piling, this is just needed between stake and stake by mutual
Connect to form the pile body of long length.
Connecting through between existing pile body sets metal end plate at the both ends of pile body, when two pile bodies need to connect
When, it is attached by the end plate for welding two pile bodies, welding job is wasted time and energy, and connection is inconvenient, in addition, weld is easy
By the chlorine salt corrosion in soil, the junction fastness of pile body is caused to be damaged.
People are although constantly explore, it is proposed that various solutions, as Chinese patent literature discloses one kind
Mechanical connection prestressed solid square pile [application number：201420316038.5], including foundation pile, connection stake and be vertically provided at
Reinforcing bar inside foundation pile and connection stake, connection stake are correspondingly arranged above foundation pile, and the cross section of foundation pile and connection stake is rectangle, base
Stake upper end and connection stake lower end are provided with annular clips, upper fastener, lower fastener and keeper, and the lower fastener is uniformly set
Put in foundation pile top, the foundation pile it is end reinforced be provided with the first card article, the first card article is socketed in lower fastener etc..Should
Having the technical effect that for scheme is easy to connect firm.But after carefully studying, it has been found that the position of upper fastener and lower fastener
Design is very unreasonable, and upper fastener and lower fastener are concordant with pile body end face, in pile body transport, carrying and connection procedure
In, if pile body end face collides fastener and lower fastener when meeting with friction, hitting, upper fastener and lower fastener
Port can be deformed or lose, so as to cause connection failure.Because the connection procedure of pile body needs to employ substantial amounts of equipment, because
This, is changed once upper fastener and lower fastener are damaged, it is necessary to employ substantial amounts of manpower and materials, very inconvenient.
The applicant is in entitled " cutting-free fast tearing sleeve couple and the interfacing part " [Granted publication applied before this
Number：CN101519876B] patent in mention a kind of connector, top pull nut and tensioning nut therein are used to tense longitudinal steel
Muscle, the program are equally used for the connection between prefabricated component such as pile body.But in embodiment and accompanying drawing not by top pull nut and
The position of tensioning nut is limited, and causes that top pull nut and tensioning nut are impaired when in use can also be present.
The content of the invention
A kind of regarding the issue above, the present invention provides tension nut sunk type that connection is reliable, not easily damaged
Prefabricated pile.
To reach above-mentioned purpose, present invention employs following technical proposal：A kind of tension nut sunk type prefabricated pile, including
Pile body, is provided with steel reinforcement cage in pile body, and described steel reinforcement cage is including some longitudinal reinforcements and what is be fixedly connected with longitudinal reinforcement is in spiral shell
The spiral reinforcement of shape is revolved, described pile body both ends are respectively fixed with some one-to-one tension nuts so that every longitudinal steel
The both ends of muscle tense a tension nut respectively, and described tension nut is sunk to inside pile body so that the end of tension nut
Horn-like connector is formed between the end of pile body.
In a kind of above-mentioned tension nut sunk type prefabricated pile, the cross section of described connector is from the end of tension nut
The direction of portion toward pile body end becomes larger.
In a kind of above-mentioned tension nut sunk type prefabricated pile, described connector is in round tapered.
In a kind of above-mentioned tension nut sunk type prefabricated pile, the both ends of described longitudinal reinforcement are provided with external diameter more than vertical
To the pier nose of reinforcing bar, the bottom of described tension nut reduces the chuck to be formed and can block pier nose.
In a kind of above-mentioned tension nut sunk type prefabricated pile, the end of described tension nut has the first chamfering,
And the first described chamfering is located on tension nut inner wall.
In a kind of above-mentioned tension nut sunk type prefabricated pile, the bottom of described tension nut and in the both sides of chuck
There is the second chamfering and the 3rd chamfering respectively, the second described chamfering and the 3rd chamfering are located on the inwall of tension nut.
In a kind of above-mentioned tension nut sunk type prefabricated pile, described pile body both ends are enclosed with angle protection cover.
Compared with prior art, the advantage of the invention is that：
1st, tension nut sinks to inside pile body and makes to be formed between the end of tension nut and the end of pile body so as to be formed
Hollow connector, plays cushioning and protection, ensure that tension nut will not be by during transport, mobile and connection etc.
To shock and breakage, it ensure that whole pile body can realize quick connection.
2nd, angle protection cover strengthens the intensity of junction, further increases the service life of bonding strength and pile body.
