Abstract
The utility model relates to a filling type road cover board. A metal casting is made into a bucket-shaped concave body in which concrete is filled to form integration. The utility model overcomes the defects of material wastage and unstability existing in the adoption of full metal casting and facilitates the closure of opening of an underground passage.
Description
The road junction closed product technical field of the utility model subordinate waterpipe, secret tunnel.
Existing pipeline, secret tunnel closed cover have plenty of cylinder iron the monoblock casting and form to have plenty of with the reinforcing bar splice and become framework, become prefabricated section with concrete casting then.More than two kinds of cover plates all have weak point, the whole cylinder iron cover plate of casting, thin, easily by opening, produce and lose and security incident, thick, promptly waste metal, inconvenience work is opened again; Prefabricated cover plate, compressive property is bad, and is cracked easily.
The utility model is for overcoming the filling type cover plate that above-mentioned cover plate weak point provides a kind of reliability and stability to possess simultaneously.
The utility model is realized by following technical proposals:
Cover plate plate body is made bottom surface sealing, open the upper end, intermediate arrangement has the matrix body metal casting of some staggered gussets, concrete casting is filled in the grid between the gusset, making concrete and metal casting is an integral body, and the cross sectional dimensions of gusset is up big and down small or the head of a nominal size greater than its thickness arranged at top.
Below in conjunction with drawings and Examples explanation the utility model content.
Fig. 1 is the utility model structure chart;
Fig. 2 is the A-A sectional view of Fig. 1;
Number in the figure is: 1-foundry goods, 2-gusset, 3-concrete
Foundry goods (1) can monoblock cast be an one with gusset (2), welding again after also can making respectively.Profile is made corresponding geometrical body as required, and the width of gusset and length are decided according to the thickness and the length and width of foundry goods, and the cross sectional dimensions of gusset is up big and down small or the head of a nominal size greater than gusset thickness arranged at top.
The shape of foundry goods (1) is the matrix body of a bucket shape, i.e. open bottom surface sealing, upper end, and the sub-box that the gusset by interlaced arrangement in the matrix body forms is used for containing concrete (3).Because the gusset cross sectional dimensions is up big and down small, even the concrete after solidifying also can be poured out under the situation of turn-over.The layout of the utility model embodiment gusset adopts three horizontal three to erect.Generally decide on profile and size.By foundry goods and the integrally formed cover plate of concrete, both can be used to cover the hole separately, also can fill up upper bed-plate earlier at the hole, with double-screw bolt cover plate and base are linked together again.
The utility model and existing covering plate structure technology relatively have and both save metal material, guarantee again the stability of cover plate, can also make lid surface and road surface harmonious, are with a wide range of applications.
Claims (2)
1, filling type road cover plate is characterized in that: cover plate (2) is bottom surface sealing, and the matrix body that intermediate arrangement has some staggered gussets (4) is opened in the upper end, and metal casting, concrete (5) water in the grid between gusset, and making concrete and cover plate is an integral body.
2, cover plate according to claim 1, the head of a nominal size greater than gusset thickness arranged at the up big and down small or top of the cross sectional dimensions of its feature gusset (4).
