Abstract
The utility model discloses a hollow floor cable passage, hollow floor include the prefabricated cavity board of polylith, and interval distribution is arranged to the prefabricated cavity board of polylith, and adjacent prefabricated cavity board passes through the dark roof beam of concrete to be connected, and the inner chamber that wherein has a plurality of blocks of prefabricated cavity boards is used as the cable passage, the inner chamber is provided with the apron as the prefabricated cavity board surface of cable passage, also have a plurality of prefabricated cavity board surfaces to be provided with the cable hole, be provided with the steel pipe that is used for communicateing the cable passage in the dark roof beam of concrete. Combine transformer substation and hollow floor's characteristics, under the prerequisite that satisfies the flat slab floor atress, utilized the inside space of floor to do the cable passage to strengthen handling to the dark roof beam of part, the passageway that passes through dark roof beam adopts the steel pipe, guarantees the intensity of structure.
Description
Technical field
This utility model is related to electrical facility technical field, more particularly to a kind of cassette ceiling cable passage.
Background technology
Existing cassette ceiling technology is used widely in civil buildings, but is not yet had using first in power engineering
Example.Transformer substation power distribution unit room and master control room span and floor height greatly, according to beamless hollow floor floor height are lowered, and reduce investment,
Simultaneously inner space can be made more attractive in appearance.
The building difference of existing cassette ceiling structure is material, shape, the difference of arrangement form of core, identical
All not pair plus sandwich space utilizes, sandwich space is the effect that starting point is filled up to point, reduces dead load.If transformer station should
When being built with cassette ceiling technology, the characteristics of for having more cable duct in transformer station room, if can be by the folder of cassette ceiling
Heart space utilization rises and is used as cable passage, is beneficial to further reduce the floor height of transformer station.
Utility model content
The purpose of this utility model is to provide a kind of cable passage of application cassette ceiling inner space.
This utility model is that the technical scheme for solving its technical problem employing is：
A kind of cassette ceiling cable passage, between cassette ceiling includes that polylith prefabricated hollow plate, polylith prefabricated hollow plate are arranged
Every distribution, contiguous prefabricated cavity plate is by the dark beam connection of concrete, wherein having the inner chamber of some blocks of prefabricated hollow plates as cable
Passage, the inner chamber is used as the prefabricated hollow plate surface of cable passage and is provided with cover plate；Also some pieces prefabricated hollow plate surfaces
It is provided with cable aperture；It is provided with for the steel pipe of communication cable passage in the dark beam of the concrete.
Further, inner chamber is non-as cable passage and non-being provided with the prefabricated hollow plate of cable aperture is provided with cystosepiment.
Further, the steel pipe is coating steel pipe.
Further, the cassette ceiling is provided with stiffener；The surrounding of the cover plate and cable aperture adopts angle steel bound edge,
The angle steel is welded with stiffener.
The beneficial effects of the utility model are：The cassette ceiling cable passage that this utility model is provided, combines transformer station
And the characteristics of cassette ceiling, on the premise of girderless floor stress is met, cable passage is done using the space inside floor, and it is right
The dark beam in part carries out reinforcement process, and the passage for passing through dark beam adopts steel pipe, it is ensured that the intensity of structure.
Description of the drawings
Fig. 1 is cassette ceiling cable passage plane graph of the present utility model；
Fig. 2 is the profile of A-A in Fig. 1；
Fig. 3 is that cassette ceiling cable passage structural strengthening of the present utility model processes plane graph.
Specific embodiment
Below in conjunction with accompanying drawing and example, the present invention will be further described.
As depicted in figs. 1 and 2, a kind of cassette ceiling cable passage of the present utility model, cassette ceiling includes that polylith is prefabricated
Cavity plate 1, the distribution of the arrangement pitch of polylith prefabricated hollow plate 1, contiguous prefabricated cavity plate 1 is connected by the dark beam 8 of concrete, wherein having
The inner chamber of some blocks of prefabricated hollow plates 1 is used as cable passage 2, and the inner chamber is used as the surface of prefabricated hollow plate 1 of cable passage 2 and sets
It is equipped with cover plate 5；The also some pieces surfaces of prefabricated hollow plate 1 are provided with cable aperture 4；And inner chamber is non-as cable passage 2 and non-sets
It is equipped with the prefabricated hollow plate 1 of cable aperture 4 and is provided with cystosepiment 7；It is provided with the dark beam 8 of the concrete logical for communication cable
The coating steel pipe 3 in road 2.Due to the application of cable passage 2, there is the impact of weakening to floor construction, therefore this utility model passes through
With FEM calculation, reinforcement process is carried out to the dark beam in part, the passage for passing through dark beam adopts steel pipe, it is ensured that the intensity of structure.
As shown in figure 3, for the structural strength for further strengthening floor construction, the cassette ceiling is provided with stiffener 9；
The surrounding of the cover plate 5 and cable aperture 4 adopts the bound edge of angle steel 6, the angle steel 6 to weld with stiffener 9.
The above, simply preferred embodiment of the present utility model, this utility model is not limited to above-mentioned enforcement
Mode, as long as it reaches technique effect of the present utility model with identical means, should all belong to protection domain of the present utility model.
