Abstract
The utility model discloses a cable trench cover plate, comprising a positive cover plate and a reverse cover plate both arranged in parallel side by side. An upward opening tongue and groove is arranged at the left side and the right side of the positive cover plate, a downward opening tongue and groove is arranged at the left side and the right side of the reverse cover plate, and the upward opening tongue and groove is butted and matched with the downward opening tongue and groove. The cable trench cover plate has the advantages of simple and stable structure and easy installation and maintenance, can effectively reduce the accident rate of cable lines, and is applied to various cable trenches.
Description
Technical field
The utility model relates to the civic building facility of cables such as being used for electric power, communication, refers to a kind of cable trench cover plate particularly.
Background technology
The cable trench is used to lay and cable facility such as place electric power, communicate by letter.In order to protect the cable in the trench, cover plate need be set on trench.At present, the cover plate that is used for the cable trench is formed by reinforcing bar and concrete cast mostly, adopts the flat mouth structure of rectangle, and every two cover plates is close to and is laid on the trench top.The cover plate of this spline structure has bigger slit after laying between cover plate and the cover plate, make rubbish foreign material etc. be easy to fall in the trench, causes potential safety hazard.Particularly in autumn, after withered and yellow leaf falls in the trench, run into just burning easily of the Mars of trench that drops into (as cigarette end etc.), thereby burn the cable of operation, the frequent accidents such as power failure, message interrupts that cause, both brought very big economic loss, and brought inconvenience for again resident's life to enterprise.Simultaneously, do not have signs such as numbering, working line title and repair call on the existing cover plate, can't determine particular location, the line name of cable.In case cable breaks down, the operation maintenance personnel can't accurately and timely find the damage source, also can't fix a breakdown timely and accurately.As seen, existing trench cover plate is extremely inconvenient for the maintenance of cable.
Summary of the invention
The purpose of this utility model is exactly to solve the deficiency that the above-mentioned background technology exists, propose a kind of simple in structure, be connected closely, sign significantly, can prevent effectively that foreign material from falling into and being easy to the cable trench cover plate that cable is safeguarded.
At above-mentioned purpose, the cable trench cover plate that the utility model is designed, comprise positive cover plate and anti-cover plate that parallel next-door neighbour arranges, the left and right sides of described positive cover plate is provided with the open type tongue and groove, the left and right sides of described anti-cover plate is provided with and the bottom-open type tongue and groove, and described upward open type tongue and groove and bottom-open type tongue and groove overlap cooperation mutually.
Further, the upper surface of described positive cover plate and anti-cover plate is equipped with Sign Board.
Further, the upper surface of described positive cover plate and anti-cover plate offers hole for hoist, and described hole for hoist internal fixation is equipped with suspension ring.
Advantage of the present utility model is: the lap-joint of positive and negative cover plate be provided with that mutual overlap joint cooperates on open type tongue and groove and bottom-open type tongue and groove, effectively sealed the slit between the cover board body, make foreign material can't fall into trench, not only simple in structure, firmly, do not influence dismounting, and can effectively reduce potential safety hazard.

Fig. 1 is the sectional structure schematic diagram of cable trench cover plate;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is the local structure for amplifying schematic diagram at A place among Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Cable trench cover plate as shown in the drawing comprises positive cover plate 1 and anti-cover plate 2, and described positive cover plate 1 left and right sides is provided with open type tongue and groove 3, is " protruding " word shape; Anti-cover plate 2 left and right sides are provided with bottom-open type tongue and groove 4, are the inverted "convex" shape shape.Positive cover plate 1 and anti-cover plate 2 closely overlap in twos, form cable trench cover plate, seal trench.The described preferred 50mm of width that goes up open type tongue and groove 3 and bottom-open type tongue and groove 4 can play the not effect in saturating slit, can make overlap joint back structure firm again.
In order to make lifting convenient, the upper surface of described positive cover plate 1 and anti-cover plate 2 offers hole for hoist 6, and described hole for hoist 6 internal fixation are equipped with suspension ring 7.During lifting, suspension hook is hooked suspension ring 7, utilize lifting tool just cover plate can be sling.In order to prevent that entering the dust foreign material in the hole for hoist 6 stops up the aperture, is equipped with dismountable port lid 8 on the described hole for hoist 6.After cover plate installs, cover port lid 8, just can effectively protect hole for hoist 6 and suspension ring 7.Need guarantee as far as possible that in installation process overlap joint closely between positive cover plate 1 and the anti-cover plate 2, the crack crack can not guarantee to use specific purpose tool to lift by crane just and can open like this, and manpower can't be opened cover plate, can prevent effectively that cover plate from being opened by the lawless person, avoid cable stolen.The hole for hoist 6 of the upper surface of positive cover plate 1 and anti-cover plate 2 offers four respectively, and four holes for hoist 6 are the symmetric arrangement state.
Attendant's maintenance for convenience, the upper surface of described positive cover plate 1 and anti-cover plate 2 is equipped with Sign Board 5.Said Sign Board 5 has marked concrete numbering, line name and repair call for every cover plate, in case meet with an accidet, when reporting to the police, the warning personnel can clearly quote line name and numbering, make the operation maintenance personnel can understand the particular location of faulty line in time, exactly, rapidly removing faults improves maintenance efficiency.
Described positive cover plate 1 and anti-cover plate 2 all can be by the C30 concrete, and Q235 steel and HPB235, HRB335 reinforcing bar or other material form.The cover plate of moulding needs that people, car etc. is had bearing capacity.
Embodiment 1: the armored concrete cover plate
Reinforcing bar is made steel reinforcement cage by the shape of said positive cover plate 1 and anti-cover plate 2, suspension ring 7 are welded in the steel reinforcement cage, the pouring pea gravel concreten is made the positive cover plate 1 and the anti-cover plate 2 of moulding.Set Sign Board 5 at positive cover plate 1 and anti-cover plate 2 upper surfaces, accomplish fluently sign and can be transported to the trench installation.
Embodiment 2: the composite material cover plate
Shape by said positive cover plate 1 and anti-cover plate 2 is made mould, with composite material direct pouring moulding.Auger shell hole in the hole for hoist 6 of positive cover plate 1 after cast molding and anti-cover plate 2 upper surfaces has the suspension ring 7 of threaded rod to be installed in the hole for hoist 6 bottom, and sets Sign Board 5 at positive cover plate 1 and anti-cover plate 2 upper surfaces, accomplishes fluently sign and can be transported to the trench installation.
