Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and particularly relates to a rainwater grate angle steel foundation reinforcement structure and an installation component. Background Art
[0002] At present, the entrances and exits of underground garages are equipped with drainage ditches and covered with rainwater grates to prevent rainwater and external water from entering the garage. At present, the foundation of rainwater grates is angle steel. The long-term rolling of vehicles in and out of the garage can easily cause the angle steel foundation to loosen, which in turn causes the grates to tilt and scrape the cars and generate vibration noise. As the number of vehicles increases, this situation becomes increasingly prominent. Utility Model Content
[0003] The utility model aims to provide a rainwater grate angle steel foundation reinforcement structure.
[0004] The utility model is achieved through the following measures:

[0006] Elbows are fixedly provided at the upper ends of the two reinforcing bars, and the elbows are welded to the angle steels, generally by double-sided welding.
[0007] The angle between the two reinforcement bars is less than 45 degrees and greater than 5 degrees.
[0008] The lower ends of the two reinforcement bars are fixedly connected by stirrups. The stirrups are of annular structure and welded to the reinforcement bars. The size of the stirrup ring is determined according to the length of the reinforcement bars and the embedding depth. The stirrup diameter can be adjusted according to actual conditions.
[0009] The length of the elbow is 5-10 times the diameter of the reinforcement bar, which increases the welding area between the elbow and the angle steel and increases the structural strength. The diameter of the reinforcement bar is generally 8-16 mm, preferably 12 mm.
[0010] The connection between the reinforcement bar and the angle steel is located in the middle of the corresponding side.
[0011] The angles between the two reinforcing bars and the corresponding sides of the angle steels to which they are connected are the same and can be 60 degrees.
[0012] The length of the reinforcing bar is generally not less than 500 mm.
[0013] On the other hand, the present embodiment provides a rainwater grate installation assembly for the entrance and exit of an underground garage, comprising angle steels symmetrically arranged on both sides above the drainage ditch, characterized in that a plurality of rainwater grate angle steel foundation reinforcement structures are arranged on the angle steels along the length direction of the drainage ditch, the rainwater grate angle steel foundation reinforcement knots are fixed on the inner wall of the angle steel, and the outer wall of the angle steel is used for placing the rainwater grate.
[0014] The interval between two adjacent rainwater grate angle steel foundation reinforcement structures is 1-2 meters. By setting up the reinforcement structure, on the one hand, the problem that the rainwater grate angle steel foundation of the garage entrance and exit is easy to loosen due to vehicle rolling over after long-term use, requires frequent maintenance, and affects normal travel during maintenance is solved. On the other hand, when pouring concrete, the angle steel is connected to the reinforcement structure, which reduces the displacement of the angle steel during the concrete pouring process and facilitates construction.
[0015] The beneficial effect brought about by the technical solution provided by the embodiment of the utility model is: according to the construction status of the existing rainwater grate angle steel foundation, an X-shaped structure composed of two reinforcing bars is designed, which can, on the one hand, strengthen the fixing effect of the rainwater grate angle steel foundation and the concrete / pavement, and on the other hand, effectively control the positioning of the rainwater grate angle steel foundation, and facilitate construction.
[0016] The rainwater grate angle steel foundation reinforcement structure can be processed and manufactured off-site in advance, and welded and fixed when installing the rainwater grate angle steel foundation, and the construction operation is simple. The overall structure is simple and can be made of steel bars at the construction site, which saves materials and has a good fixing effect, while reducing the later maintenance of the angle steel foundation.
