Description

Technical Field

[0001] The utility model relates to the technical field of ground patching, in particular to a modular building ground patching structure. Background Technique

[0002] In the clean workshops of traditional buildings, the drainage pipes in the clean areas are generally installed by embedding or drilling holes. After drilling holes, sleeves are installed. After the drainage pipes pass through the sleeves, sealing, edge covering and other treatments are carried out, and there is no need to patch the ground. In the outdoor modular or modular second floor, holes can be easily located and drilled because there is a space below the module where people can enter for installation and maintenance.

[0003] This method cannot be realized in the indoor floor-mounted modular clean workshop project. The drainage pipes in the indoor modular clean workshop need to embed drainage pipes in the workshop where the modular buildings are placed. The indoor modular buildings are positioned according to the embedded drainage pipes and finally placed on the ground in the workshop. There is no operating space below the first-floor module. To connect the embedded pipes to the equipment or sanitary appliances in the modular building, the indoor modular building needs to be pre-drawn with secondary piping in advance. The connection between the secondary piping and the embedded pipes is pre-opened in the form of a 200*200mm square hole in the modular building to ensure that the embedded pipes and the modular building will not be affected by tiny errors and cannot be positioned and placed during on-site in-place docking. Therefore, after the module is accurately positioned, even if there is a little tiny error between the on-site embedded drainage pipe and the secondary piping in the module, it will not affect the connection and installation of the drainage pipe. In this way, there is an installation space for the pipes in the module, but how to patch the square hole has become a problem. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a modular building ground patching structure, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a modular building ground patching structure, including: a sealing plate for connecting with the ground and a support sleeve for connecting with the drainage pipe. A through hole is opened at the center of the surface of the sealing plate. The support sleeve is connected to the surface of the sealing plate. The position of the support sleeve corresponds to the position of the through hole. A foaming agent filling layer is arranged between the support sleeve and the drainage pipe. PVC floor covering layers are arranged on the surfaces of the sealing plate and the support sleeve. A hole covering plate is connected to the surface of the PVC floor covering layer, and the hole covering plate is connected to the surface of the drainage pipe.

[0006] Preferably, the sealing plate is made of square steel plate, the thickness of the sealing plate is 2mm, the side length of the sealing plate is 350mm, and the diameter of the through hole is 89mm.

[0007] Preferably, the height of the support sleeve is 2 mm, the thickness of the support sleeve is 2 mm, and the inner diameter of the support sleeve is equal to the diameter of the through hole.

[0008] Preferably, one end of the support sleeve is welded to the surface of the sealing plate.

[0009] Preferably, the height of the masking plate is 30 mm, and silicone sealing strips are provided between the masking plate and the drain pipe and between the masking plate and the PVC floor covering layer.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the modular building backfill ground structure, by setting a sealing plate, a support sleeve, a foaming agent filling layer, a PVC floor covering layer and a masking plate, the sealing plate and the support sleeve for backfilling the ground are sleeved into the embedded drain pipe in the modular building. The sealing plate is embedded in the area of the levelling layer that has been cleaned. The sealing edge of the backfill ground sealing plate and the steel plate of the modular ground under the modular building levelling layer is fully welded. The gap between the support sleeve and the embedded drain pipe is filled with a foaming agent to form a foaming agent filling layer. After laying the PVC floor covering layer, the masking plate is installed around the drain pipe, so that the support sleeve on the integrated steel plate of the drain pipe and the backfill ground is covered inside the masking plate, which is convenient for backfilling the modular ground and keeps the modular ground clean.
