Description
Technical field
The present invention relates to a kind of building anchor bolt.
Background technology
Crab-bolt includes: intumescent crab-bolt is the crab-bolt utilizing expansion piece extruding anchor hole hole wall to form anchorage effect.It is utilize moving towards of vertebral body and expansion piece, promotes expansion piece to expand, produce extender pressure with hole wall concrete, and produce, by shearing friction effect, a kind of assembly that withdrawal resistance realizes connected piece is anchored.Moment of torsion controls formula intumescent crab-bolt: hole in advance with specific drilling tool, complete to expand installation displacement controllable intumescent crab-bolt through controlling screw torque size: hole in advance with target drill, realize expanding by the relative displacement of sleeve with conehead and expanding anchor bolt is installed: by the concrete grooving reaming again of foot of hole, what utilize that the concrete pressure-bearing surface formed after reaming and crab-bolt expand between enlarged footing is mechanical interlocked, it is achieved a kind of assembly to connected piece anchoring.Pre-reaming common anchor bolt: by specific drilling tool grooving reaming in advance from reaming Special anchor bolt: first hole with specific drilling tool, crab-bolt carries cutter, grooving reaming voluntarily during installation, reaming, installation once complete Anchor bolt: this is the external a kind of foundation bolt introduced, the foundation bolt of general import equipment is all this Anchor bolt, and especially Europe equipment, has an open type metallic sheath at the rear portion of crab-bolt, after squeezing into ground, being wrenched rib-loop, opening swell is fixed.Crab-bolt at the bottom of rear cutout: be exactly the expansion bolt with set very common on our market, it is impossible to individually fix, it is necessary to fixing after extruding mutually with fixture, mainly the structure restriction of its opening sleeve.
Current existing crab-bolt structure is complicated, installs inconvenience, and structural stability is poor, and structural strength is not high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of compact conformation, easy for installation, the building anchor bolt of good fixing effect.
For solving the problems referred to above, the present invention adopts the following technical scheme that
A kind of building anchor bolt, including head, load cover, afterbody and screw rod, described head, load cover and afterbody are formed in one setting, described screw rod is located in head, described screw rod is connected with head threads, described screw rod side is provided with crossed pan head, described screw rod opposite side is provided with spring, described crossed pan head and the one-body molded setting of screw rod, nut and pad are installed in the middle part of described screw rod, it is provided with catch in described load cover, described catch is fixing with load cover to be connected, described head surface is provided with reinforcement, described reinforcement is fixing with head to be connected.
As preferably, described screw rod is rustless steel screw rod.
As preferably, described spiro rod length is more than 15cm.
As preferably, described nut is flexibly connected with screw rod.
As preferably, described pad is rubber sheet gasket.
The invention have the benefit that the head of setting, load cover and afterbody are formed in one maintenance compact conformation；The screw rod arranged is connected with head threads, load cover can be made to bend after rotating screw rod, keeps good fixing effect；The reinforcement arranged keeps head structural strength high；The compact conformation when catch arranged keeps load cover to bend.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of building anchor bolt of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of building anchor bolt, including head 1, load cover 2, afterbody 3 and screw rod 4, described head 1, load cover 2 and afterbody 3 are formed in one setting, described screw rod 4 is located in head 1, described screw rod 4 is threadeded with head 1, described screw rod 4 side is provided with crossed pan head 5, described screw rod 4 opposite side is provided with spring 6, described crossed pan head 5 and the one-body molded setting of screw rod 4, nut 7 and pad 8 are installed in the middle part of described screw rod 4, it is provided with catch 9 in described load cover 2, described catch 9 is fixing with load cover 2 to be connected, described head 1 surface configuration has reinforcement 10, described reinforcement 10 is fixing with head 1 to be connected.
Described screw rod 4 is rustless steel screw rod, keeps long service life.
Described screw rod 4 length is more than 15cm so that easy to adjust reliably.
Described nut 7 is flexibly connected with screw rod 4, keeps convenient fixing.
Described pad 8 is rubber sheet gasket, has good shockproof effect.
The invention have the benefit that the head of setting, load cover and afterbody are formed in one maintenance compact conformation；The screw rod arranged is connected with head threads, load cover can be made to bend after rotating screw rod, keeps good fixing effect；The reinforcement arranged keeps head structural strength high；The compact conformation when catch arranged keeps load cover to bend.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention be not limited thereto, any change expected without creative work or replacement, all should be encompassed within protection scope of the present invention.
