Description

Technical Field

[0001] The present application relates to the technical field of modular buildings, and in particular to a modular building floor and a method for using a home floor drain in a modular building floor. Background Art

[0002] Modular construction is an emerging building structure system that uses each room as a modular unit. All units are prefabricated in the factory, transported to the site, and assembled into the entire building through reliable connection methods. The modular building floor is a plate-like structure and is installed on the ground through keels.

[0003] Regarding the above-mentioned related technologies, since modular building floors do not have drainage pipes pre-buried in the floor slabs, and there are no drainage pipes preset in the sedimentation tank, ordinary floor drains cannot be fixed for use, and there is a defect that it is inconvenient to connect the floor drain. Summary of the Invention

[0004] In order to solve the defect of being inconvenient to connect a floor drain, the present application provides a modular building floor and a method for using a home floor drain in the modular building floor.

[0005] In the first aspect, the present application provides a modular building floor, which adopts the following technical solution: a cement fiber board is provided with two layers, and the two layers of cement fiber boards are fixedly connected; the cement fiber board is provided with a through hole, and the through hole passes through the cement fiber board; the cement fiber board located above is provided with a makeshift groove; a PVC flange is inserted into the through hole, and the flange plate of the PVC flange is inserted into the makeshift groove; the PVC flange is fixedly connected to the cement fiber board; a PVC short pipe is inserted into the PVC flange and fixedly connected to the PVC flange; a waterproof layer is laid on the upper surface of the cement fiber board and the PVC flange.

[0006] By adopting the above technical solution, when installing a floor drain on a modular building floor, first, through holes and make-shift grooves are opened in sequence on the cement fiber board, and then the PVC short pipe and the PVC flange are fixed and then fixed to the cement fiber board, and then a waterproof layer is laid; after laying the waterproof layer, the installation conditions of a traditional concrete floor are simulated, and the installation of a conventional floor drain is realized, which facilitates the connection of the floor drain; at the same time, the remaining end of the PVC short pipe is convenient for connecting other transfer pipes, which facilitates the subsequent connection of different drainage pipes across modules.

[0007] Preferably, the waterproof layer is also laid inside the PVC flange.

[0008] By adopting the above technical solution, the waterproof layer is laid in the PVC flange to improve the overall waterproofness of the modular building floor. Since the PVC short pipe is inserted into the PVC flange, the sealing performance of the PVC short pipe and the PVC flange is improved.

[0009] Preferably, an adapter tube is connected to one end of the PVC short tube away from the PVC flange.

[0010] By adopting the above technical solution, the provision of the transfer pipe can facilitate workers to connect different drainage pipes across modules.

[0011] Preferably, a check assembly is provided in the PVC short tube, and the check assembly includes: a check ring, which is horizontally arranged and fixedly connected to the PVC section tube; a check tube, which is fixedly connected to the lower surface of the check ring and is connected to the PVC short tube; a check bowl, which is located below the check tube, and the upper end surface of the check bowl is higher than the lower surface of the check tube; an adjusting rod, which is fixedly connected to the upper surface of the check ring, and the adjusting rod intersects with the mid-vertical line of the check ring; a connecting rod, which is vertically arranged, with one end fixedly connected to the check bowl, and the remaining end passes through the check tube and the check ring and passes through the adjusting rod, and the connecting rod is slidably connected to the adjusting rod; a limit rod, which is located above the adjusting rod and fixedly connected to the connecting rod; a limit spring, which is sleeved on the circumferential outer wall of the connecting rod, fixedly connected to the limit rod and pressed against the adjusting rod.

[0012] By adopting the above technical solution, when the floor drain is in normal use, part of the discharged water remains in the check bowl, and the upper end surface of the check bowl is higher than the lower end surface of the check pipe, so the odor from the drain pipe will not be back into the room; when impurities are deposited, press the connecting rod downward, and the gap between the check bowl and the check ring will increase, and the impurities will be discharged.

[0013] Preferably, a clamping groove is provided on the inner wall of the check tube; a clamping part is connected to the upper surface of the check bowl, and the clamping part includes a clamping rod and a clamping block. The length direction of the clamping rod is the same as the length direction of the check tube. The clamping rod is fixedly connected to the check bowl and the clamping block, and the clamping block is clamped in the clamping groove.

[0014] By adopting the above technical solution, when the drain has not been used for a long time, the connecting rod is pulled upwards, and the connecting rod drives the clamping block to move upwards. When the clamping block is inserted into the clamping groove, the lower end surface of the check pipe is pressed against the upper surface of the check bowl, thereby achieving an odor-proof effect.

[0015] In a second aspect, the present application provides a method for using a household floor drain in a modular building floor, which adopts the following technical solution:

[0016] The method for using a home floor drain in a modular building floor comprises the following steps:

[0017] S1. Preparation of cement fiberboard: Two layers of cement fiberboard are bonded and fixed, and a through hole is provided. A recess is provided on the upper cement fiberboard, and the recess is provided coaxially with the through hole.

[0018] S2. Prepare and install the PVC flange and PVC short pipe; insert the PVC short pipe into the PVC flange and glue it in place; place the PVC flange into the through hole and the groove, glue it in place, and fill the gap between the cement fiberboard and the PVC flange so that the upper surface of the PVC flange is flush with the upper surface of the cement fiberboard.

[0019] S3, waterproof layer laying;

[0020] S4, laying floor tiles;

[0021] S5. Install floor drain.

[0022] By adopting the above technical solution, the conditions for installing floor drains on traditional concrete floors are simulated through the setting of through holes, recesses, PVC flanges, and PVC short pipes, thereby achieving the effect of facilitating the installation of floor drains; at the same time, the setting of the waterproof layer improves the overall waterproof sealing.

[0023] Preferably, in step S3, the waterproof layer is made of waterproof coiled material or painted with waterproof paint; and the waterproof layer is painted or pasted on the inner wall of the PVC short tube inserted in the PVC flange.

[0024] Preferably, in step S2, the connecting rod is pulled, the connecting rod drives the check bowl to press against the check tube, and the clamping block is inserted into the clamping groove; the connecting rod is pushed, and the clamping block is disengaged from the clamping groove.

[0025] By adopting the above technical solution, when the drain has not been used for a long time, the connecting rod is pulled upwards, and the connecting rod drives the clamping block to move upwards. When the clamping block is inserted into the clamping groove, the lower end surface of the check pipe is pressed against the upper surface of the check bowl, thereby achieving an odor-proof effect.

[0026] To sum up, the present application includes at least one of the following beneficial technical effects: when installing a floor drain on a modular building floor, first, through holes and makeshift grooves are opened on the cement fiber board in sequence, and then the PVC short pipe and the PVC flange are fixed and then fixed to the cement fiber board, and then a waterproof layer is laid; after laying the waterproof layer, the installation conditions of the traditional concrete floor are simulated and the installation of the conventional floor drain is realized, which facilitates the connection of the floor drain; at the same time, the remaining end of the PVC short pipe is convenient for connecting other transfer pipes, which facilitates the subsequent connection of different drainage pipes across modules.

[0027] 1. When installing a floor drain on a modular building floor, first, create through holes and make way grooves on the cement fiberboard, then secure the PVC short pipe and PVC flange to the cement fiberboard, and finally lay a waterproof layer. After laying the waterproof layer, the installation conditions of a traditional concrete floor are simulated, allowing for the installation of a conventional floor drain, making it easier to connect the floor drain. At the same time, the remaining end of the PVC short pipe is convenient for connecting to other adapter pipes, making it easier to connect different drainage pipes across modules.

[0028] 2. When the floor drain is in normal use, part of the discharged water remains in the check bowl. The upper end surface of the check bowl is higher than the lower end surface of the check pipe. Therefore, the odor from the drain pipe will not be returned to the room. When impurities are deposited, press the connecting rod downward. At this time, the gap between the check bowl and the check ring increases, and the impurities are discharged.

[0029] 3. When the drain has not been used for a long time, pull the connecting rod upwards. At this time, the connecting rod drives the clamping block to move upwards. When the clamping block is inserted into the clamping groove, the lower end surface of the check pipe presses against the upper surface of the check bowl, thereby achieving the deodorizing effect.

During the connection process, the upper surface of the PVC flange 2 is coplanar with the upper surface of the cement fiber board 1.

[0037] refer to Figure 1 and Figure 3 A waterproof layer 4 is applied to the cement fiber board 1 and the PVC flange 2, and is also applied to the inside of the PVC flange 2. The waterproof layer 4 can be made of a waterproof membrane or a waterproof coating. The waterproof layer 4 is applied by brushing or adhering to the inner wall of a short PVC tube 3 inserted into the PVC flange 2. An adapter tube 5 is connected to the end of the short PVC tube 3 facing away from the PVC flange 2.

[0038] When installing the floor drain 9 on the modular building floor, first, a through hole 11 and a makeshift groove 12 are opened in sequence on the cement fiber board 1, and then the PVC short pipe 3 and the PVC flange 2 are fixed and then fixed to the cement fiber board 1, and then the waterproof layer 4 is laid; after laying the waterproof layer 4, the installation conditions of the traditional concrete floor are simulated and the installation of the conventional floor drain 9 is realized, which achieves the effect of facilitating the connection of the floor drain 9; at the same time, the remaining end of the PVC short pipe 3 is convenient for connecting to other transfer pipes 5, which facilitates the subsequent connection of different drainage pipes across modules.
