Description

Technical Field

[0001] This utility model relates to the field of buried pipe pressure testing technology, and in particular to a floor drain device suitable for buried pipe pressure testing. Background Technology

[0002] A floor drain is a drainage device that connects the floor to the drainage pipe system. It is an important interface between the drainage system and the indoor floor, and its main function is to quickly and effectively remove standing water from the floor to keep it dry and prevent water accumulation. During building construction and pipe installation, due to the strength design requirements of the relevant drainage system, buried or concrete-embedded pipes need to undergo pressure testing to ensure the sealing and reliability of the pipe system. Traditional prefabricated floor drain devices, after being welded to the pre-buried pipes, cannot be effectively sealed on the construction site, resulting in the floor drain failing to meet the relevant pressure test requirements after being connected to the pre-buried pipes. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a floor drain device suitable for buried pipe pressure testing, which can solve the problem that traditional finished floor drain devices are difficult to seal after welding with pre-buried pipes, thus making it impossible to conduct pressure testing.

[0004] Therefore, the present invention adopts the following technical solution: A floor drain device suitable for buried pipe pressure testing includes a floor drain base plate, several floor drain box plates, a floor drain groove plate, and a floor drain cover plate. The floor drain base plate has a reserved pipe opening in the middle for the pre-buried pipe to pass through. The floor drain box plates are welded to the periphery of the floor drain base plate to form a box with an internal cavity. The floor drain groove plate is welded onto the floor drain box plate. The floor drain groove plate has a cover plate groove for placing the floor drain cover plate inside. The floor drain cover plate is detachably embedded in the cover plate groove and its bottom overlaps the floor drain box plate. The floor drain cover plate has several drainage openings.

[0005] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions: The diameter of the reserved pipe opening is at least 2mm larger than the diameter of the adjacent embedded pipe.

[0006] The drain box panels are joined together, and the drain box panels are joined to the drain base plate, with the welds located on the inner side.

[0007] A gap of at least 2mm is provided between the drain cover and the cover groove.

[0008] The drain base plate, the drain box plate, and the drain groove plate are welded together to form a closed whole and are embedded in concrete.

[0009] The total opening area of ​​the plurality of drainage openings is not less than one-third of the area of ​​the drain cover.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects: the pre-embedded pipe can extend an appropriate length from the bottom plate of the drain for pressure testing and sealing. After the pressure test, the extended pre-embedded pipe portion is cut off before the drain cover is installed, which meets the requirements for pressure testing on the construction site; the structure is simple, easy to obtain materials on site for fabrication and adjustment, saves construction costs, and improves construction efficiency.

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote elements with the same or similar functions throughout. However, it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting this utility model. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] This utility model provides a floor drain device suitable for buried pipe pressure testing, including a floor drain base plate 1, several floor drain box plates 3, floor drain groove plates 4, and floor drain cover plates 6. The floor drain base plate 1 has a reserved pipe opening 2 in the middle for the pre-buried pipe to pass through. The floor drain box plates 3 are welded to the periphery of the floor drain base plate 1 to form a box with an internal cavity. The floor drain groove plates 4 are welded to the floor drain box plates 3. The floor drain groove plates 4 have a cover plate groove 5 for placing the floor drain cover plate 6 inside. The floor drain cover plate 6 can be detachably embedded in the cover plate groove 5 and its bottom overlaps the floor drain box plates 3. The floor drain cover plate 6 has several drainage openings 7.

[0017] like Figure 1As shown, in this embodiment, the drain box plate 3 and the drain bottom plate 1 together form a square box. In actual construction, the drain box plate 3 and the drain bottom plate 1 can be combined to form a frustum-shaped box as needed.

[0018] The diameter of the reserved pipe opening 2 is at least 2mm larger than the diameter of the adjacent pre-buried pipe, so that the pre-buried pipe can pass smoothly through the drain base plate 1 and be welded to it.

[0019] Fillet welds are used between the floor drain box plates 3 and between the floor drain box plates 3 and the floor drain base plate 1, with the welds located on the inner side, to ensure the sealing of the pre-embedded floor drain device.

[0020] A gap of at least 2mm is provided between the drain cover 6 and the cover groove 5.

[0021] The drain base plate 1, drain box plate 3, and drain groove plate 4 are welded together to form a closed whole and are embedded in concrete.

[0022] The materials of the drain base plate 1, drain box plate 3, drain groove plate 4 and drain cover plate 6 are all the same as those of the pre-buried pipes.

[0023] The total opening area of ​​several drain holes 7 shall not be less than one-third of the area of ​​the drain cover 6, so as to increase the water collection speed and reduce the amount of water accumulation.

[0024] This utility model provides a floor drain device suitable for buried pipe pressure testing, the operation method of which includes the following steps: S1. Before the pressure test of the pre-embedded pipeline connected to the floor drain device, the floor drain cover plate 6 is not installed on the floor drain device. The pre-embedded pipeline passes through the floor drain bottom plate 1 and extends a certain length out of the floor drain. The pre-embedded pipeline is welded to the floor drain bottom plate 1 so as to seal the pipeline under pressure. S2. After the pressure test of the pre-buried pipe connected to the floor drain device is completed, the part of the pre-buried pipe that extends out of the floor drain bottom plate 1 is cut off and polished smooth. Then the floor drain cover plate 6 is installed.

[0025] The removable design of the drain cover 6 not only facilitates the pressure test of the buried pipe, but also allows the drain cover 6 to be opened at any time to clean the dirt inside the drain device, reducing the cost of later inspection and maintenance.

[0026] Based on the description and drawings of this utility model, those skilled in the art can easily manufacture or use the floor drain device of this utility model that is suitable for buried pipe pressure testing, and can produce the positive effects described in this utility model.
