The water-proof cable crane span structure
Technical field:
The utility model relates to a kind of cable testing bridge, relates in particular to a kind of water-proof cable crane span structure.
Background technique:
At present, " " becomes people can not obtain scarce element, and power station, electric substation send electricity and be transported to huge numbers of families, and each link is all most important during this, and the protection of cable also is the most important thing.
In the existing power distribution unit building, cable testing bridge leads to the place's box out of outdoor body of wall, and conventional way is for being provided with lintel on top, hole, and this way only can satisfy the earthquake resistant code requirement of place, hole, can't realize the protection to the cable of crane span structure outlet direction.And cable testing bridge leads to outdoor most no waterproof measure, the cable that causes after exposing to the weather because of aging leak electricity, the indoor rainwater that pours into of short circuit and power distribution unit causes case such as equipment failure of common occurrence.
The model utility content:
The purpose of this utility model is to provide a kind of waterproof simple in structure, effective, effectively reduces accident rate, prolongs the cable water-proof cable crane span structure in working life.
The purpose of this utility model is implemented by the following technical programs: a kind of water-proof cable crane span structure, comprise cable testing bridge and retaining edge, described cable testing bridge passes construction wall, described retaining is fixed on the described construction wall and places described cable testing bridge top along an end, and described retaining is along turning on the edge of the other end.
Advantage: effectively reduced because of the cable that causes after exposing to the weather because of agingly leak electricity, short circuit and the indoor rainwater that pours into of power distribution unit cause accident potential such as equipment failure, the use that keeps off the edge simultaneously helps the whole stressed of place, big hole, avoid earthquake middle and upper part masonry to drop and make being pounded cable failure, cause unnecessary loss.
Description of drawings:
Fig. 1 is a cross-sectional view of the present utility model.
Cable testing bridge 1 keeps off along 2 construction wall 3.
Embodiment:
Embodiment 1:(is as shown in Figure 1) a kind of water-proof cable crane span structure, comprise cable testing bridge 1 and retaining along 2, cable testing bridge 1 passes construction wall 3, and retaining is fixed on the construction wall 3 and places cable testing bridge 1 top along 2 one ends, and retaining is along turning on the edge of 2 the other ends.
Pass construction wall 3 places at cable testing bridge 1 and make the retaining of waterproof along 2, can prevent effectively that rainwater from directly falling the water proof structure way that passes body of wall place cable testing bridge 1, keep off along 2 when enriching elevation of building by setting up waterproof, the part is avoided running into because of cable is aging conductive materials such as water and is caused hidden danger such as electric leakage, short circuit, and keeps off along 2 simultaneously and help antidetonation.
