Description
Technical Field
The utility model relates to a precast concrete slab technical field especially relates to a high strength anticorrosion bolt external member that precast concrete slab junction was used.
Background
In the construction of building engineering, the sleeve pipe of PVC material is generally used as the bolt external member for reinforcing the template, that is, the PVC sleeve pipe with the diameter 2mm larger than that of the bolt is used for template reinforcement on the bolt, and in addition, after the concrete pouring is finished, the bolt is pulled out from the PVC pipe, and only the PVC pipe is left in the concrete for later installation and use.
However, in practical application, the PVC pipe wall is thin and easy to damage, so that part of bolts can not be pulled out to cause waste, part of the bolts can be embedded into an unset concrete slab by using metal spiral pipes, and the bolts are directly installed through bolt reinforcement after solidification.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a high-strength anti-corrosion bolt kit for the joints of precast concrete slabs.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a high strength anticorrosion bolt external member that precast concrete slab junction was used, includes the screwed pipe, the welded mounting in screwed pipe top has hidden groove, screwed pipe bottom welded mounting has the stopper, screwed pipe inner wall bottom is equipped with the rubber gasket, the bolt main part is installed to the screwed pipe internal rotation, bolt main part top welded mounting has the nut, the spacing groove has been seted up to the nut bottom, the spacing groove top is equipped with the metal gasket through bolt main part cover, the protection piece is installed to bolt main part bottom joint.
Preferably, the top end of the threaded pipe extends into the limiting groove.
Preferably, the top end of the nut is provided with a hexagonal opening.
Preferably, the nut is completely embedded into the hidden groove in the closed state.
Preferably, the bolt body has a length longer than the threaded pipe.
Preferably, the surfaces of the threaded pipe, the hidden groove and the limiting block are coated with anti-corrosion coatings.
Compared with the prior art, the beneficial effects of the utility model are that: during the use with the screwed pipe embedding not in the concrete slab mould that the shaping solidifies, keep latent groove top and concrete slab surface in the horizontality, the later stage can be installed the bolt main part through the nut rotation to the screwed pipe in, until the protection piece pushes up the rubber gasket, perhaps the screwed pipe top pushes up the metal gasket of spacing inslot, wherein the stopper has played whole firm effect in concrete slab, whole nut installation and stealthy inslot.
The utility model has the advantages of reasonable overall design, easy operation convenient to use, the steadiness is strong, does not influence holistic planarization of concrete slab and use.
