Abstract
Description
Technical Field
[0001] The invention relates to the field of building construction, and in particular to an installation structure and a construction method for a pre-buried pipe for a floor drain. Background Art
[0002] The floor drain is an important interface between the drainage pipe system and the indoor floor. As an important component of the drainage system in a house, its performance directly affects the quality of indoor air and is very important for odor control in the bathroom.
[0003] Before installing the bathroom floor drain, it is necessary to install the embedded pipe in advance. After the embedded sleeve, waterproof layer and waterproof protective layer are constructed, the lightweight material filling layer is backfilled, and finally the floor drain is installed while the floor tile surface layer is constructed, thereby completing the installation of the entire floor drain process. However, this type of embedded pipe has two shortcomings in actual use. First, after the bathroom waterproof and protective layer construction is completed, water needs to be stored in the bathroom for a water storage test to verify the waterproof construction effect. However, after the water storage test is completed, it is inconvenient to drain the water for the water storage test, and the water can only be cleaned manually, which is time-consuming and laborious. On the other hand, after the bathroom floor tile surface layer is completed, during the long-term use of the bathroom, because it is a water-related room, as the use time increases, a certain amount of water will form at the bottom of the bathroom, which cannot be effectively removed, thereby affecting the service life of the waterproof layer at the bottom of the bathroom.
[0004] Therefore, it is necessary to improve the structure of the existing floor drain pre-buried pipe installation structure so that it can effectively solve the problems existing in the prior art. Summary of the invention
[0005] In order to solve the above problems, the floor drain embedded pipe installation structure of the present technical solution can effectively drain the accumulated water generated during the use of the bathroom by opening a drainage hole in the circumferential direction of the embedded pipe, thereby improving the service life of the waterproof layer. At the same time, the waste water generated by the water storage test after the construction of the bathroom waterproof and protective layer is completed can be quickly discharged through the drainage hole, avoiding manual cleaning and speeding up the construction progress.
[0006] A floor drain embedded pipe installation structure comprises an embedded pipe installed in a structural layer and a floor drain connecting pipe installed in cooperation with a connecting sleeve; the upper end of the embedded pipe passes through a waterproof protective layer and extends to a lightweight material filling layer, and drainage holes for internal drainage are opened in the circumferential direction of the embedded pipe.
[0007] Furthermore, a return water guide ring is installed on the outer sleeve in the circumferential direction of the embedded pipe, and the return water guide ring is fittedly installed on the waterproof protective layer.
[0008] Furthermore, there are multiple drainage holes, and the multiple drainage holes are evenly distributed in the same circumferential direction of the embedded pipe.
[0009] Furthermore, the overflow water guide ring is a trumpet-shaped structure that is larger at the top and smaller at the bottom. The upper end of the overflow water guide ring extends to the lightweight material filling layer, and the lower end of the overflow water guide ring extends to the structural layer and is fixedly connected with the embedded pipe.
[0010] Furthermore, the drainage hole is arranged at a height in the vertical direction that is the same as the installation height of the lower end of the overflow water guide ring.
[0011] Furthermore, it also includes a connecting sleeve connected to the upper end of the embedded pipe, and the floor drain connecting pipe is inserted into the connecting sleeve.
[0012] A construction method for installing a pre-buried pipe for a floor drain comprises the following steps:
[0013] S1: Install the embedded pipe in the structural layer and the connecting sleeve on the upper end of the embedded pipe to ensure that the installation height of the embedded pipe and the connecting sleeve meets the construction requirements;
[0014] S2: Multiple drainage holes are evenly opened in the circumferential direction of the embedded pipe at a suitable height, and a return overflow water guide ring is fixedly connected and installed in the circumferential direction of the embedded pipe to ensure that the lower end of the return overflow water guide ring is at the same height as the drainage hole;
[0015] S3: Waterproof materials and waterproof layers are constructed above the structural layer. After the waterproof layer meets the construction requirements, lightweight materials are backfilled. At the same time, the floor drain connecting pipe is connected and installed with the connecting sleeve to ensure the sealing of the connection.
[0016] S4: Carry out floor tile laying construction and install the floor drain on the upper end of the floor drain connecting pipe.
[0017] The beneficial effects of the present invention are as follows: the floor drain embedded pipe installation structure of the present technical solution can effectively drain the accumulated water generated during the use of the bathroom by opening a drainage hole in the circumferential direction of the embedded pipe, thereby improving the service life of the waterproof layer. At the same time, the waste water generated by the water storage test after the construction of the bathroom waterproof and protective layer is completed can be quickly discharged through the drainage hole, avoiding manual cleaning and speeding up the construction progress.

[0019] Figure 1 This is a schematic diagram of the overall installation of the present invention;
[0020] Figure 2 It is a top view schematic diagram of the overflow water guide ring of the present invention. DETAILED DESCRIPTION
[0021] Figure 1 This is a schematic diagram of the overall installation of the present invention; Figure 2This is a top view schematic diagram of the overflow water guide ring of the present invention. As shown in the figure, a floor drain embedded pipe installation structure includes an embedded pipe 1 installed in the structural layer 3 and a floor drain connecting pipe 10 installed in cooperation with a connecting sleeve 9; the upper end of the embedded pipe 1 passes through the waterproof protective layer 4 and extends to the lightweight material filling layer 5, and the embedded pipe 1 is provided with a drainage hole 8 for internal drainage in the circumferential direction; the floor drain embedded pipe installation structure of the present technical solution can effectively drain the accumulated water generated in the use of the bathroom by opening a drainage hole in the circumferential direction of the embedded pipe, thereby improving the service life of the waterproof layer. At the same time, the wastewater generated by the water storage test after the construction of the bathroom waterproof and protective layer is completed can be quickly discharged through the drainage hole, avoiding manual cleaning and speeding up the construction progress.
[0022] In this embodiment, the pre-buried pipe 1 is provided with a return water guide ring 2 on the outer sleeve in the circumferential direction, and the return water guide ring 2 is fitted on the waterproof protective layer 4. The pre-buried pipe 1 is provided with a plurality of drainage holes 8 in the circumferential direction to facilitate the subsequent drainage of accumulated water. The return water guide ring 2 is installed on the pre-buried pipe 1 on the outer sleeve, and is fixedly connected and installed to ensure its sealing performance. The lower surface of the return water guide ring 2 is fitted on the waterproof protective layer to facilitate the formation of an accumulated water guiding effect.
[0023] In this embodiment, the drainage holes 8 are multiple and evenly distributed in the same circumferential direction of the embedded pipe. The drainage holes 8 can be set to be multiple and evenly distributed in the circumferential direction of the embedded pipe, so that the internal accumulated water can be guided and discharged from the drainage holes 8 into the embedded pipe.
[0024] In this embodiment, the overflow water guide ring 2 is a trumpet-shaped structure with a large top and a small bottom. The upper end of the overflow water guide ring 2 extends to the lightweight material filling layer 5, and the lower end of the overflow water guide ring 2 extends to the structural layer 3 and is fixedly connected with the embedded pipe. The overflow water guide ring 2 is a trumpet-shaped structure, which is convenient for collecting and guiding the internal accumulated water. The overflow water guide ring 2 is attached to the waterproof protective layer 4, which also plays a protective role on the waterproof layer.
[0025] In this embodiment, the drainage hole 8 is arranged at the same height in the vertical direction as the installation height of the lower end of the overflow water guide ring 2. Figure 1 As shown, the position height of the drainage hole 8 is at the same height as the lower end of the overflow water guide ring 2, which is convenient for effectively draining the internal accumulated water and reducing the amount of internal accumulated water.
[0026] In this embodiment, a connecting sleeve 9 connected to the upper end of the embedded pipe is also included, and the floor drain connecting pipe 10 is inserted into the connecting sleeve. The connecting sleeve 9 is arranged at the upper end of the embedded pipe 1, and the floor drain connecting pipe 10 is inserted into the connecting sleeve 9. The three are installed in coordination to form a closed structure to ensure the installation stability and sealing of the overall structure.
[0027] In this embodiment, the overflow water guide ring 2 and the waterproof protective layer 4 are attached to the mounting surface to form an inclined angle with the vertical direction, and the inclined angle is 50-60°. Figure 1 As shown, the installation position of the overflow water guide ring 2 and the waterproof protective layer 4 (i.e., the cross section in the figure) forms an angle of 50-60° with the vertical direction, which is convenient for better collecting the accumulated water inside and effectively discharging the accumulated water, thereby increasing the service life of the waterproof layer.
[0028] In this embodiment, the upper surface of the waterproof protective layer 4 forms an inclination angle with the horizontal direction, and the inclination angle is 3-5°. The upper surface of the waterproof protective layer 4 forms a small inclination angle with the horizontal direction, so that the accumulated water on the upper surface of the waterproof protective layer can flow into the overflow water guide ring 2 in time and effectively, and be quickly discharged to reduce the amount of accumulated water.
[0029] A construction method for installing a pre-buried pipe for a floor drain comprises the following steps:
[0030] S1: Install the embedded pipe 1 in the structural layer 3, and install the connecting sleeve 9 on the upper end of the embedded pipe 1 to ensure that the installation height of the embedded pipe and the connecting sleeve meets the construction requirements; the embedded pipe 1 can be installed simultaneously during the structural layer construction to ensure that the embedded pipe 1 is installed stably and the upper end height meets the requirements, and the connecting sleeve 9 is installed at the same time to facilitate the subsequent connection and installation of the floor drain connecting pipe 10;
[0031] S2: A plurality of drainage holes 8 are evenly opened in the circumferential direction of the embedded pipe at a suitable height, and a return overflow water guide ring 2 is fixedly connected and installed in the circumferential direction of the embedded pipe to ensure that the lower end of the return overflow water guide ring 2 is at the same height as the drainage hole 8; after the drainage hole 8 on the embedded pipe is opened, the return overflow water guide ring 2 is installed to ensure the sealing performance of the connection between the two. At this time, a waterproof test can be performed. Before the test, the drainage hole needs to be sealed with a rubber plug. After the test is completed, the rubber plug is removed to drain the water;
[0032] S3: Waterproof materials and waterproof layers are constructed above the structural layer. After the waterproof layer meets the construction requirements, lightweight materials are backfilled. At the same time, the floor drain connecting pipe is connected and installed with the connecting sleeve to ensure the sealing of the connection.
[0033] S4: Carry out floor tile laying construction and install the floor drain on the upper end of the floor drain connecting pipe.
[0034] By setting a drain outlet on the embedded pipe, the wastewater generated by the water storage test after the construction of the bathroom waterproof and protective layer is completed can be quickly discharged through the drain outlet, and the accumulated water generated during the use of the bathroom in the later stage can also be effectively discharged. At the same time, a backflow water guide ring 2 is set to prevent the wastewater discharged downward through the floor drain during the use of the bathroom from overflowing at the drain outlet and flowing into the lightweight filling layer of the bathroom. After the construction of the embedded sleeve, waterproof layer, and waterproof protective layer is completed, the floor drain is finally installed while the floor tile surface layer is constructed, thereby completing the installation of the entire floor drain process.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
