Description
Technical field
The present invention relates to a kind of anchor head, more specifically to a kind of concrete self-locking anchor head belongs to anchorage technology field.
Background technique
In civil structure engineering field, it is often necessary to be mended on existing concrete structure and set built-in fitting, currently, rear-mounted
Anchorage style mainly has intumescent anchor bolt, chemically-planted steel bar, expanding anchor bolt.
Chinese utility model patent " a kind of concrete self-locking inserted link and matched reaming bit " (patent announcement number:
2404619Y, the day for announcing: on November 8th, 2000) reaming bit being made of drilling rod, chisel head and pedestal is proposed, it bores
Bar is an elongated reinforcing bar, and chisel head is two petal chisel heads, the upper end and drilling rod be it is hinged, pedestal is a upper end for the short shape steel of cone cell
Muscle is connect with drilling rod with slide bar.The drill bit and pedestal are put into the bottom in hole, when drilling rod rotates and moves downward, two petals
Inclined-plane of the chisel head on pedestal stretches to hole wall, cuts out a tapered wedge surface, on hole wall in order to install self-locking anchor bar.This is practical
Novel because its structure is simple, self-locking performance is good, and anchor force is larger, obtains in rock or concrete anchoring engineering and largely answers
With；But since the drill bit and the main anchor force of anchor pole are provided by the rock or concrete supporting body of single layer anchor head, work as carrying
When body such as rock or low concrete strength, the stress concentration at the position is difficult to that anchor pole is made to give full play to efficiency.
Summary of the invention
It is an object of the invention to for the existing concentration of the stress existing for the inserted bar of lock be difficult to that anchor pole is made to give full play to effect
The problems such as energy, provide a kind of concrete self-locking anchor head.
To achieve the above object, institute is the present invention using technical solution: a kind of concrete self-locking anchor head, including anchor pole
And supporting platform seat, it is provided with hollow hole in the supporting platform seat, in the hollow hole of the anchor trend insertion supporting platform seat, anchor
Bar bottom is provided with reinforcing bar nut, and the hollow hole top aperture is greater than anchor pole outer diameter and is less than reinforcing bar nut outer diameter, hollow
Hole lower part aperture is greater than reinforcing bar nut outer diameter, is socketed with self-locking device on anchor pole, and the self-locking device is slidably matched with anchor pole,
It is located at the top of self-locking device on anchor pole and is provided with reinforcing bar nut.
The anchor pole is finish rolling deformed bar.
The supporting platform seat is the pedestal that a top is rotary table, lower part is cylinder, and the self-locking device is located at branch
It supports above pedestal.
The self-locking device is that muti-piece self-locking head is concatenated by connecting steel wire.
Compared with prior art, the beneficial effects of the present invention are:
Compared with prior art, this self-locking anchor head is easy installation and reliable, can be more convenient and fully open；Meanwhile even if holding
When carrier such as rock or low concrete strength, this self-locking anchor head can also give full play to efficiency.
Detailed description of the invention
Fig. 1 is the self-locking pre-structure schematic diagram of present invention the first transaction of a day's business.
Fig. 2 is the self-locking preceding perspective view of present invention the first transaction of a day's business.
Fig. 3 is structural schematic diagram after present invention the first transaction of a day's business is self-locking.
Fig. 4 is perspective view after present invention the first transaction of a day's business is self-locking.
In figure, anchor pole 1, supporting platform seat 2, self-locking device 3, reinforcing bar nut 4, hollow hole 5, connection steel wire 6.
Specific embodiment
Below in conjunction with Detailed description of the invention and specific embodiment, the present invention is described in further detail.
Referring to Fig. 1 to Fig. 4, a kind of concrete self-locking anchor head, including anchor pole 1 and supporting platform seat 2, anchor pole 1 are a round metal
Barred body.Hollow hole 5 is provided in the supporting platform seat 2,1 lower part of anchor pole is inserted into the hollow hole 5 of supporting platform seat 2, anchor
1 bottom of bar is provided with reinforcing bar nut 4, which is formed with external screw thread, and reinforcing bar nut 4 is screwed in 1 bottom of anchor pole；Described
5 top aperture of hollow hole is greater than 1 outer diameter of anchor pole and is less than 4 outer diameter of reinforcing bar nut, and 5 lower part aperture of hollow hole is greater than reinforcing bar nut 4
Outer diameter.Self-locking device 3 is socketed on anchor pole 1, the self-locking device 3 is slidably matched with anchor pole 1；It is located at self-locking dress on anchor pole 1
It sets 3 tops and is provided with reinforcing bar nut 4, anchor pole 1 is formed with external screw thread at this, this reinforcing bar nut 4 screws on anchor pole 1.
Referring to Fig. 1 to Fig. 4, specifically, the anchor pole 1 is finish rolling deformed bar.
Referring to Fig. 1 to Fig. 4, specifically, the supporting platform seat 2 is the pedestal that a top is rotary table, lower part is cylinder,
The self-locking device 3 is located at 2 top of supporting platform seat.
Referring to Fig. 1 to Fig. 4, specifically, the self-locking device 3 is that muti-piece self-locking head is concatenated by connecting steel wire 6.
Muti-piece self-locking head herein is 8 pieces or more, usually 8 pieces.
Referring to Fig. 1 to Fig. 4, this self-locking anchor head is used in basement anti-floating or rock foundation anchors, and can be used for common straight hole anchor
It is anchored in hole.In use, anchor pole 1 falls on bottom hole along hollow hole 5, supporting the self-locking head of self-locking device 3 with pressure
It struts in the top round table surface of pedestal 2, and fits with round table surface.Therefore, this self-locking anchor head can not only correspondingly increase anchor pole
Or the withdrawal resistance of built-in fitting, anchor rod anchored reliability can also be improved.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, and above structure all shall be regarded as belonging to
Protection scope of the present invention.
