Outside in prefabricated part body is stretched out at metalwork both ends respectively.
As a preference, ventilation hole is distributed in the prefabricated part body, is provided with pvc pipe in the ventilation hole.
Two layers of reinforcing bar group is equipped with as a preference, in the prefabricated part body to correspond to inside and outside prefabricated part body.
As a preference, through-hole partition is provided on the ventilation hole.
The beneficial effects of the utility model are: eliminating a large amount of works constructed at the scene originally by the technology of prefabricated component
Sequence, prefabricated component can be conducive to keep specification consistent, and structural strength is high by prefabrication, batch production, save material, peace
Dress is convenient, and furthermore prefabricated component may be reused, and meets current environmentally protective trend.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The utility model is further elaborated.For the thorough explanation present invention, some spies can be related in following description

These of place describe and state that the others skilled in the art into fields can more effectively introduce their work essence.
Referring to Fig.1, a kind of switch-box prefabricated component, the prefabricated part body 2 including being located at 1 downside of switch-box, the prefabricated component
Ontology 2 is the concrete well shape structure of upper and lower ends opening, and 2 upper end of prefabricated part body is provided with channel steel 3, described prefabricated
2 lower end side edge of part ontology is provided with threading recess 4 and is connected to the cable shaft 5 on side.Prefabricated part body 2 can by prefabrication,
Batch production is conducive to keep specification consistent, and structural strength is high, saves material, easy for installation.Furthermore prefabricated part body 2 can
To reuse, meet current environmentally protective trend.
Ground connection flat metalwork 6 is provided in the prefabricated part body 2, wherein 6 both ends of ground connection flat metalwork point
It Shen Chu not the interior outside of prefabricated part body 2.
Ventilation hole 7 is distributed in the prefabricated part body 2, is provided with pvc pipe in the ventilation hole 7.The prefabricated component sheet
It is equipped in body 2 inside and outside the corresponding prefabricated part body 2 of two layers of reinforcing bar group 8.
Through-hole partition 9 is provided on the ventilation hole 7.
During actual construction, it should be noted that:
Illustrate:
1. outdoor switch box foundation uses prefabricated component, prefabricated component selects concrete strength C40, using clear-water concrete work
Skill.
2. cable shaft uses cast-in-place basis.Bear down on one and the concrete strength C25 of bottom plate；Outdoor switch box foundation reinforcing bar uses
