Abstract
The utility model discloses a kind of pre-buried channel flow for being easy to repair, including conduit body and pre-buried bar, the conduit body bottom portion is provided with screw, the screw is divided into bolt head bore and bolt rod aperture on the same center of circle, the conduit body is provided with orientation block below screw, and the orientation block also is provided with screw, and the pre-buried bar is adapted with screw, the pre-buried bar surface is provided with external screw thread, and the pre-buried bar bottom is provided with nut.This is easy to the pre-buried channel flow of maintenance, by the screw hole design of conduit body into two layers above and below bolt head bore and bolt rod aperture, the top of pre-buried bar can be made completely into screw, the use of conduit body is not influenceed；The bottom of pre-buried bar is provided with nut, by increasing capacitance it is possible to increase pre-buried bar is by the steadiness in cement of nuzzling, moreover it is possible to taken out pre-buried bar using machinery, and conduit body is repaired；Therefore, the utility model is simple in construction, reasonable in design, with social utility's value.
Description
Technical field
The utility model belongs to technical field of traffic transportation, and in particular to a kind of pre-buried channel flow for being easy to repair.
Background technology
At present in subway construction, when affiliated facility is fixedly mounted, drilled after general use, the side fixed with expansion bolt
Formula, over time, expansion bolt easily loosen under oscillatory load, and the easily generation dust in installation process；Or adopt
The mode installed with pre-embedded steel slab, when mounted, it is necessary to be welded and external power supply, installation effectiveness is low, and welding easily make it is attached
Facility deformation produces stress concentration；There is a method in which be exactly by the way of pre-buried installation, it is in advance that conduit is pre- by anchor pole
It is embedded in concrete, this mode efficiency highest.
Existing subway conduit typically all by the way of fixed welding, is fixed and welded together pre-buried bar and chute,
This is resulted in can not be repaired when conduit is damaged, and all pre-buried channel flows all can not be normally used, influence construction
Progress；Accordingly, it would be desirable to one kind is designed when conduit is damaged, the pre-buried channel flow that can conveniently repair.
Utility model content
The purpose of this utility model is to provide a kind of pre-buried channel flow for being easy to repair, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides following technical scheme：A kind of pre-buried channel flow for being easy to repair, including
Conduit body and pre-buried bar, the conduit body bottom portion be provided with screw, the screw be divided on the same center of circle bolt head bore and
Bolt rod aperture, the conduit body is provided with orientation block below screw, and the orientation block also is provided with screw, the pre-buried bar and spiral shell
Hole is adapted, and the pre-buried bar surface is provided with external screw thread, and the pre-buried bar bottom is provided with nut.
It is preferred that, it is provided with internal thread in the screw of the orientation block.
It is preferred that, the top of the pre-buried bar is circle, and is adapted with bolt head bore.
It is preferred that, the top of the pre-buried bar is provided with inner hexagonal hole.
It is preferred that, it is provided with film layer on the outside of the pre-buried bar and orientation block.
Technique effect of the present utility model and advantage：This is easy to the pre-buried channel flow of maintenance, by the screw hole design of conduit body
Two layers above and below into bolt head bore and bolt rod aperture, the top of pre-buried bar can be made completely into screw, conduit body is not influenceed
Use；The orientation block of conduit body bottom portion, can prevent that the position of pre-buried bar shifts pre-buried when, after influence
Maintenance；It is set to circular at the top of pre-buried bar, and provided with inner hexagonal hole, facilitates and be installed at the top of pre-buried bar in bolt head bore；In advance
The bottom for burying bar is provided with nut, by increasing capacitance it is possible to increase pre-buried bar is by the steadiness in cement of nuzzling, moreover it is possible to taken pre-buried bar using machinery
Go out, conduit body is repaired；Film layer is set on the outside of pre-buried bar and orientation block, can prevent cement from entering screw, shadow
Ring the use of pre-buried bar；Therefore, the utility model is simple in construction, reasonable in design, with social utility's value.
Brief description of the drawings
