Description
Technical field
A kind of template support instrument is the utility model is related to, is specifically to be related to a kind of quick detachable split bolt.
Background technology
Existing industrial building uses frame structure mostly.In frame structure, the sectional dimension of frame column it is larger and
Height is higher.During these frame columns are poured into a mould, if supporter during supporting module only on the outside of master plate carrys out branch hold mode
Plate, then swollen mould phenomenon is easily produced in casting process, it is difficult to ensure that the quality of the frame column finally poured into.To solve this
Problem, building trade are generally during support template, and some split bolts are evenly arranged along the short transverse of frame column
Ensure the sectional dimension of frame column finally poured into.Common split bolt is mainly revolved by the driving screw of a root long and a pair
Nut mounted in driving screw both ends forms., can be on driving screw away from every end one when using common split bolt supporting module
It is stupefied in being fixed at fixed distance, then, the lumps of wood is worn at the both ends of driving screw, then driving screw is passed through template, then, in template
Outside is fastened using outer stupefied, fastener and nut, can so ensure that template avoids template from becoming during casting concrete
Shape.After the completion of operation is poured, driving screw is set in concrete this split bolt, must will be exposed at concrete during dismounting
The bolt part of outside is prescinded, then the lumps of wood is picked from concrete, finally to staying in the end of the bolt part in concrete
Preservative treatment is carried out, and the hole to being left after the rejecting lumps of wood block up and smears processing, it not only deals with more troublesome, Er Qiezao
It is higher into larger waste of material, use cost.
Utility model content
The purpose of this utility model is：Quick detachable split bolt that is a kind of simple in construction and can reusing is provided.
The technical solution of the utility model is：A kind of quick detachable split bolt, including driving screw and spinning are in driving screw
The nut at both ends, is also movably installed with a metal sleeve outside the driving screw, and the external diameter of the metal sleeve is from one end to another
One end is gradually reduced, and the endoporus of the metal sleeve is more than the straight hole of driving screw external diameter for internal diameter, is welded in the bigger diameter end of metal sleeve
Connect and be fixed with first annular baffle plate, be provided with corresponding the second ring baffle for holding out against cooperation in the miner diameter end of metal sleeve, this first
Ring baffle is equal with the internal diameter of metal sleeve with the internal diameter of the second ring baffle, and the first annular baffle plate and the second annular are kept off
The external diameter of plate is all higher than the external diameter of metal sleeve bigger diameter end, and activity insertion gold is also integrally convexly equipped with second ring baffle
Belong to the butt tube of annular gap between casing tube internal hole and driving screw.
Backing plate is additionally provided between the first annular baffle plate and the second ring baffle and corresponding nut, positioned at the gold
Belong in annular gap of the sleeve pipe bigger diameter end between driving screw and metal sleeve endoporus and be also fitted with rubber bushing, rubber lining
The outer end of set is equipped with the gear edge coordinated with the first annular baffle plate outer plate surface block.
Quick detachable split bolt of the present utility model uses is set with the tapered metal sleeve of profile outside driving screw,
When removing split bolt, without driving screw is blocked, after it need to extract driving screw out from metal sleeve, from metal sleeve
Miner diameter end, which slowly beats, to be completely drawn out metal sleeve from the concrete poured, and its overall structure is simple, using very
It is convenient, and a full set of split bolt can be reused, and greatly reduce the cost of template support.
Brief description of the drawings
Fig. 1 is the structural representation of the quick detachable split bolt of the utility model.
Embodiment
The specific embodiment of quick detachable split bolt of the present utility model as shown in figure 1, it include a driving screw 1 with
And spinning is also movably installed with a metal sleeve 2, the metal in two nuts 8 at the both ends of driving screw 1 outside driving screw 1
The endoporus of sleeve pipe 2 is the straight hole that internal diameter is more than the external diameter of driving screw 1, and the external diameter of the metal sleeve 2 gradually subtracts from one end to the other end
It is small so that the profile of the metal sleeve 2 is in butt frustum shape, the metal sleeve 2 bigger diameter end by being welded and fixed
There is first annular baffle plate 3, the second ring baffle 4 that cooperation is correspondingly held out against during an installation be provided with the miner diameter end of metal sleeve 2,
The first annular baffle plate 3 is equal with the internal diameter of metal sleeve 2 with the internal diameter of the second ring baffle 4, the first annular baffle plate 3 with
The external diameter of second ring baffle 4 is all higher than the external diameter of metal sleeve bigger diameter end, and two ring baffles 3,4 are mainly used in support template
When clamping mold outside, wherein, be also integrally convexly equipped with the second ring baffle 4 and match somebody with somebody with the endoporus activity grafting of metal sleeve 2
The butt tube 5 of conjunction, can be according to being poured using the cooperation of butt tube 5 with metal sleeve 2 fixed on the second ring baffle 4
Shear wall, column equal in width, coordinate the template spacing of supporting and adjust the first annular ring baffle 4 of baffle plate 3 and second away from
From.
Further, in the present embodiment, it is between the first annular ring baffle 4 of baffle plate 3 and second and corresponding nut 8
Backing plate 7 is additionally provided with, and in the annular gap at the bigger diameter end of metal sleeve 2 between driving screw 1 and the endoporus of metal sleeve 2 also
Rubber bushing 6 is fitted with, the outer end of the rubber bushing 6 is equipped with the gear edge coordinated with the first annular outer plate surface block of baffle plate 3, together
When, rubber mat plate 9 is provided between the second ring baffle 4 and corresponding backing plate 7.In metal sleeve bigger diameter end, rubber bushing is set
The concentricity between the driving screw and metal sleeve during support template in split bolt is may insure, ensures support template
Construction quality, rubber bushing are drawn it out when setting gear along convenient dismantle.
