Description
Technical field
The invention belongs to building anchor bolt technical field, and expansion anchor is built more particularly, to one kind.
Background technology
Building expansion anchor be pipeline branch/hang/bracket or equipment are fixed on the wall of building, on floor, institute on column
A kind of special thread connector.In building structure, crab-bolt is because of its reliability anchored and the flexibility installed, in many
Aspect just progressively substitutes built-in fitting, fix in shelf, equipment installation, glass curtain wall installation, plug-in stone material, external wall outer insulation material
Largely used in the engineering such as anchoring, erection of doors and windows, support of pipelines, building decoration and renovation of building, reinforcing.
Building expansion anchor have the advantages that it is easy for installation, but there is also it is certain the shortcomings that.Such as installation thing dismounting or with
After change place, the former screw rod that crab-bolt on building wall is installed on through punching can not be easily removed, and can only can just be taken by cutting
Go out, taking-up is troublesome in poeration, returns wall reparation and causes certain trouble.Also for example, crab-bolt is when being installed on wall, due to wall
When soft or mounting hole the aperture of wall material matter is slightly larger, when tightening nut and fixing crab-bolt, the expansion tube meeting of crab-bolt sometimes
Rotate and skid, cause crab-bolt installation insecure.Therefore, it is necessary to improved.
The content of the invention
The purpose of the present invention is in view of the deficiency of the prior art, there is provided one kind building expansion anchor, it has
It is non-slip, firmly install and the characteristics of convenient disassembly.
To achieve these goals, the technical solution adopted in the present invention is：One kind building expansion anchor, including nut,
Screw rod and expansion assembly, the upper end of screw rod are provided with the fastening thread coordinated with nut, and the expansion assembly includes expansion tube
And screw head,
Some cracks along expansion tube axial direction are provided with the tube wall of expansion tube lower end, are set on the outer tube wall of expansion tube lower end
There are some positioning convex strips along expansion tube axial direction；
Screw head is cone type, and the upper end of screw head is provided with screw hole, be provided with the ring surface of screw head several with it is swollen
The corresponding location lug in crack on tube expansion；The lower end of screw rod is provided with the bolt coordinated with screw hole, the hand of spiral on bolt with
The direction of fastening thread is identical, and the upper end of screw rod is provided with dismounting end；Screw head is screwed onto the lower end of screw rod；
Screw rod is from bottom to top interspersed in expansion tube, and the upper end of screw rod is spirally connected nut.
Gasket is also arranged with the screw rod.
The lower port in the crack is arranged to wide-mouth port.
The both sides of the screw rod upper end are respectively arranged with plane.
With the above structure, the invention has the advantages that compared with the prior art,：Determine on expansion tube of the present invention
Position raised line can have the function that screens to expansion tube when mounted, prevent expansion tube rotates from skidding, firmly install it；Screw rod
Head is connected with screw rod by the removably being mutually spirally connected, and screw rod easy removal from wall is got off, and screw head
On location lug clamping corresponding with crack, screw head will not rotate skiddings when dismantling screw rod, and then ensure that screw rod can be light
Dismounting.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention（Front view）.
Fig. 2 is the top view of screw rod.
Fig. 3 is the bottom view of expansion tube.
