Abstract

The utility model relates to a fixing device for a concrete sleeve. The sleeve is uniformly distributed in the chamber of a prefabricated part formwork, wherein a rubber ring is arranged in the sleeve, a lead screw penetrates through the rubber ring, a lock nut is screwed on the lead screw on the left side of the rubber ring, a small gasket is sheathed on the lead screw between the lock nut and the rubber ring, a larger gasket is sheathed on the lead screw on the outer side of the prefabricated part formwork, and a fixing nut is arranged on the lead screw outside the large gasket. The fixing device for the concrete sleeve has the advantages that the defect is overcome at first; compared with the prior art, the sleeve of the concrete prefabricated part is not displaced and deviated after the sleeve is fixed, the operation is simple to perform, the accuracy is improved, and the requirement on the size of the sleeve in the prefabricated part is met.

Description

A kind of concrete sleeve fixture
Technical field
A kind of concrete sleeve of the utility model fixture, what relate to is the technical field of concrete prefabricated element, is applied to the fixing of concrete prefabricated element inner sleeve.
Background technology
Sleeve in former concrete prefabricated element is fixed by reinforcing bar binding, easily produces sleeve displacement when casting and compacting of concrete, and after concrete prefabricated element moulding, originally sleeve grouting position is all offset, and grouting material cannot normally pour into.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect, existing technique is improved, change concrete prefabricated element and rely on the fixing old technology of reinforcing bar binding, design is by screw mandrel and rubber choker block fixed muffle, and be connected with concrete prefabricated element template, guarantee the fixing of sleeve, avoid sleeve in a kind of concrete sleeve fixture of concrete prefabricated element superior displacement.
For addressing the above problem the technical scheme of employing, be: comprise locking nut, minipad, rubber ring, large pad, hold-down nut, screw mandrel, it is characterized in that: in precast-concrete form cavity, be evenly equipped with sleeve, sleeve is built-in with rubber ring, in the hole of rubber ring, be installed with screw mandrel, on the screw mandrel in rubber ring left side, be screwed with locking nut, on screw mandrel between locking nut and rubber ring, cover has minipad, and on the screw mandrel in precast-concrete form outside, cover has large pad, and the screw mandrel outside large pad is provided with hold-down nut.
Obvious advantage and the effect implemented after this technology are: be first to overcome above-mentioned defect, compared with prior art, after the sleeve of concrete prefabricated element is fixing, can not produce displacement and skew, simple to operate, improve precision, guaranteed the dimensional requirement to sleeve in prefabricated components.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model,
Wherein, 1-sleeve, 2-locking nut, 3-minipad, 4-rubber ring, 5-precast-concrete form, the large pad of 6-, 7-hold-down nut, 8-screw mandrel
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
See accompanying drawing 1, in precast-concrete form 5 cavitys, be evenly equipped with sleeve 1, sleeve 1 is built-in with rubber ring 4, in the hole of rubber ring 4, be installed with screw mandrel 8, on the screw mandrel 8 in rubber ring 4 left sides, be screwed with locking nut 2, on screw mandrel 8 between locking nut 2 and rubber ring 4, cover has minipad 3, and on the screw mandrel 8 in precast-concrete form 5 outsides, cover has large pad 6, and the screw mandrel 8 outside large pad 6 is provided with hold-down nut 7.
See accompanying drawing 1, during work, in precast-concrete form 5 cavitys, be evenly equipped with sleeve 1, first locking nut 2 and minipad 3 are fixed on screw mandrel 8, pack in sleeve 1 after putting on rubber ring 4, then put into precast-concrete form 5,8 one of screw mandrels pass by the hole to be provided on precast-concrete form 5, with large pad 6 and hold-down nut 7 lockings, rubber ring 4 is pressed, and rubber ring 4 is by expansion spreading, sleeve 1 is firmly fixed and leaned against on precast-concrete form 5, carry out pouring concrete.
