Abstract
The utility model discloses a kind of cable channel cover plate that is provided with preformed hole, be provided with preformed hole on cover plate, described preformed hole is a semi-circular through hole; Described semi-circular through hole is arranged at the end of described cover plate; The diameter of described semi-circular hole is greater than the external diameter of cable; On the inwall of described semi-circular hole, be also provided with the bound edge for the protection of circular port edge.The utility model is because preformed hole adopts semicircular structure, can treat that cable laying customizes cover plate later again, can guarantee the perpendicularity of the cable after laying, guarantee that cable laying meets code requirement, avoided because cable laying does not meet the code requirement phenomenon of doing over again, and then when guaranteeing construction schedule, manpower and materials have been saved.
Description
Technical field
The utility model relates to cable trench cover structure, relates in particular to a kind of cable channel cover plate that is provided with preformed hole.
Background technology
In cable transmission line cable duct bank engineering, usually need to arrange cable and step on bar cable trough.The peristome of this cable trough generally all adopts cover plate sealing.For the ease of the cable in cable trough is connected with electric power bar, often need on the cover board to offer preformed hole for wearing cable.
At present, as shown in Figure 1, conventional preformed hole 11 ˊ are generally arranged at the middle part of concrete cover 1 ˊ, steel plate 12 ˊ bound edges for the edge of preformed hole.During construction, first need cable 2 ˊ to pass cover plate 1 ˊ with preformed hole, then this cover plate is arranged to cable below, guarantee that preformed hole is vertical with cable.But; during actual use; because the manufacture of cover plate has certain error, error accumulation when a certain amount of, there will be according to cover plate preformed hole and the cable off plumb phenomenon of the size customization before laying; this cable being obliquely installed not only easily damages cable covering; and may be excessive and can not meet the requirement of power construction standard to cable laying due to angle of inclination, and then need to do over again, again cabling; waste time and energy, waste resource.
Therefore, need a kind of easy for installation, accurate positioning of research badly, be not easy to destroy cable floor cable channel cover plate.
Utility model content
Because the above-mentioned defect of prior art, the utility model proposes a kind of easy for installation, be not easy to destroy cable floor, accurate positioning, the time saving and energy saving cable channel cover plate that is provided with preformed hole.
For achieving the above object, the utility model provides a kind of cable channel cover plate that is provided with preformed hole, is provided with preformed hole on cover plate, and described preformed hole is a semi-circular through hole; The end that is centered close to described cover plate of described semi-circular through hole; The diameter of described semi-circular through hole is greater than the external diameter of cable; On the inwall of described semi-circular through hole, be also provided with the steel plate for the protection of the edge of semi-circular hole.
Further, the side that described cover plate contacts with road terrace is also provided with the binding structure of cover sheet corner.
Further, described binding structure is angle steel.
Further, described angle steel is inequilateral structure, one side the side contacting with road terrace that is arranged at described cover plate of described angle steel, the another side of described angle steel is arranged at described cover plate towards a side of cable trough; The length of described first side is greater than the length of described Second Edge.
The beneficial effects of the utility model:
The cable channel cover plate that is provided with preformed hole of the present utility model, because preformed hole adopts semicircular structure, the customization of can going again after cable laying completes is provided with the cover plate of preformed hole, can guarantee the cable perpendicularity after laying, meet cable laying code requirement, avoided because cable laying does not meet the phenomenon of doing over again that code requirement causes, when guaranteeing construction schedule, saved manpower and materials.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Accompanying drawing explanation
The existing cable trench cover structure schematic diagram that is provided with preformed hole of Fig. 1;
Fig. 2 is the structural representation that the present embodiment is provided with the cable channel cover plate of preformed hole;
Fig. 3 is that the A of Fig. 2 is to structural representation.
Embodiment
As shown in Figures 2 and 3, the present embodiment has proposed a kind of cable channel cover plate that is provided with preformed hole.Preformed hole on cover plate 1 is a semi-circular through hole 11, and semi-circular through hole 11 is arranged at the end of cover plate 1.During use, two cover plates 1 combination can be formed to the through hole that a complete current supply cable passes.Owing to adopting two semi-circular hole structures, during installation, needn't first cable be passed to this hole, can after cable laying, reset the position of preformed hole, guaranteed the requirement of laid processes to cable perpendicularity.
The diameter of semi-circular through hole 11 is greater than the external diameter of cable 2.Impaired in order to prevent the edge of cover plate, on the inwall of semi-circular hole 11, be also provided with the steel plate 12 for the protection of circular port edge.
The side that cover plate 1 contacts with road terrace (not shown) is also provided with the angle steel 3 of cover sheet corner, and the first side 31 of angle steel 3 is arranged at the side that cover plate contacts with road terrace, and the Second Edge 32 of angle steel is arranged at cover plate towards a side of cable trough.Because angle steel face is hidden under road terrace completely, therefore, in cover sheet corner, can also avoid due to angle steel be exposed to outdoor, the generation of phenomenon such as skid of the pedestrian that may cause when air humidity is large wrestling or bicycle.
In order to save construction cost, angle steel 3 is set to inequilateral structure, and the length of angle steel 3 first sides is greater than the length of Second Edge.
In other embodiments, also can adopt the steel of channel-section steel or other structures or other material as bound edge material, the utility model is not limited to this.
Concrete service condition of the present utility model is as follows: during installation, and first cabling; Then the cover plate that preformed hole is not set is installed; According to two cover plates that are provided with preformed hole of real space customization after laying, cable is positioned in the formed through hole of semi-circular hole of two cover plates, to guarantee that cable is perpendicular to preformed hole again.Adopt cover plate of the present utility model, not only can guarantee that the position of preformed hole and the size of cover plate meet the requirement of laying standard, and easy construction, save trouble and labor.If the later stage need to be changed cable, only need open this with the cover plate of semi-circular hole, omitted due to the needed time and efforts of cable punching hole, guaranteed construction schedule.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection range by claims.
