Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of building engineering, especially a floor drain for deformation joint. BACKGROUND
[0002] The building deformation joint is a construction joint reserved to prevent additional deformation and stress in the structure under the action of external factors, leading to cracking and even destruction of the building. In order to prevent rainwater from entering the deformation joint, a rain baffle is usually installed at the deformation joint, and then a floor drain is installed in the rain baffle. A drain pipe is connected to the water outlet at the bottom of the floor drain, so that the water entering the rain baffle flows into the drain pipe through the floor drain, and then flows out through the drain pipe. In order to increase the sealing between the floor drain and the rain baffle of the deformation joint, glass glue is usually applied at the floor drain to prevent rainwater from entering between the floor drain and the rain baffle of the deformation joint, i.e. to prevent rainwater from dripping down along the outer wall of the floor drain.
[0003] The floor drain is installed inside the rain baffle of the deformation joint to drain the accumulated rainwater in the rain baffle of the deformation joint. However, in the actual installation process, the top of the floor drain is higher than the lower surface of the inner wall of the rain baffle of the deformation joint. In this case, when the liquid level of the rainwater in the rain baffle of the deformation joint is lower than the top of the floor drain, the rainwater cannot enter the floor drain smoothly, thereby affecting the thoroughness of the rainwater discharge in the rain baffle of the deformation joint. Moreover, when the rainwater stays in the rain baffle of the deformation joint for a long time, it is easy to increase the erosion of the rainwater on the rain baffle of the deformation joint, thereby affecting the service life of the rain baffle of the deformation joint. Therefore, the present application provides a floor drain for deformation joint to meet the needs. SUMMARY
