Description
Technical Field
The utility model relates to a rain-proof apron especially relates to a rain-proof apron of square entrance to a cave.
Background
In the engineering of industry and building, underground pipe gallery engineering, traffic, water conservancy etc. owing to the needs such as technology configuration, production life use, often can set up various portals in positions such as floor, roofing, wall, the portal can be square portal, circular portal, interim portal, permanent portal, open portal or sealed portal etc. as required. Some holes are required to be in a closed state under normal conditions and are opened only when needed, such as an accessible hole on a roof, an accessible hole on the top of a storage bin, an inspection hole and the like; the holes are generally provided with movable cover plates, so that the holes can be opened and closed conveniently; the movable cover plate can be a movable reinforced concrete cover plate under the general condition, and can also be a movable steel cover plate, and the steel cover plate is generally applied to openings under the action of medium and light loads, in particular to openings on floors, wall surfaces and the top of a storage bin due to the advantages of small dead weight, convenience in manufacturing and moving and the like. The movable reinforced concrete cover plate is usually used for a hole or a trench near the ground with a large load on the plate surface.
The openings at different positions on different buildings have different functional requirements on the cover plate, such as: the movable steel cover plate on the common floor opening only needs to plug the opening to prevent people and objects from falling; the movable steel cover plate on the ordinary roof opening needs to plug the opening to avoid people and objects falling, and also needs to have a rainproof function. The existing movable steel cover plate is too simple in structure and smaller than the flashing top surface of the hole, so that when the flashing top of the hole is inclined or uneven, accumulated water on the flashing top of the hole is easy to permeate into the hole; in addition, the bottom of the existing movable cover plate is only provided with a frame for positioning, no filler for sealing is used, the movable cover plate is not fixed with the opening through flashing, the sealing performance and the waterproof performance are poor, and rainwater on the outer side of the opening cannot be effectively prevented from permeating, so that the existing movable steel cover plate is only suitable for common openings with low sealing performance.
