Description

Technical Field

[0001] This invention belongs to the field of decoration technology, specifically a device and method for creating a drainage channel for backfilling foamed concrete in toilets. Background Technology

[0002] A sunken bathroom refers to a bathroom structure where the bathroom structure is partially or entirely lowered from the corresponding floor level during the main construction (usually 40cm) to allow the horizontal drainage pipes to be buried. Then, it is backfilled with lightweight materials (ceramsite or foamed cement grout), and the structural surface only needs to have one opening for the drainage riser to be used.

[0003] During the construction of a sunken bathroom, drainage channels need to be created on the surface of the backfill layer. These channels are distributed across the backfill layer to guide any water that seeps into the backfill layer into the drain pipes. To improve construction quality, the drainage channels should be distributed as evenly as possible, and their depth and width should meet certain requirements. The channels should also be kept as straight as possible to improve water drainage efficiency.

[0004] Currently, drainage channels are created manually by cutting open the backfill layer using ordinary tools. Since the backfill layer has not solidified when the drainage channels are created, it is not convenient for workers to stand on it. In addition, it is necessary to ensure that the drainage channels are evenly distributed. Therefore, it is troublesome, labor-intensive, inefficient, and the quality of the drainage channels cannot be guaranteed. Summary of the Invention

[0005] To address the above problems, this invention provides a device and method for creating drainage channels in the backfill of foamed concrete for toilets. This solves the problem that in the prior art, drainage channels in the backfill layer of toilets need to be manually created, resulting in uneven distribution of drainage channels, low precision, and impaired drainage performance.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A device for creating drainage channels in foamed concrete backfill for toilets includes a support rod with a positioning seat at the lower end for inserting a drainage pipe; the upper edge of the positioning seat has grooved rods that can be flipped up and down in a ring shape; the grooved rods are fixed to the side wall of the support rod by corresponding snap-fit ​​devices.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] Using this device, drainage channels can be quickly and evenly opened radially from the drainage pipe outlet on the backfill layer. The quality and uniformity of the drainage channels can be guaranteed. The grooving rod can be used to quickly form drainage channels with a gradually decreasing depth from the near end to the far end of the drainage pipe outlet, which facilitates the rapid drainage of accumulated water.

[0010] As a further improvement to the above solution, a handle is provided at the upper end of the support rod.

[0011] The improved technology has the following effect: the specially designed handle makes it easier to pick up the device.

[0012] As a further improvement to the above solution, the cross-section of the slotted rod is V-shaped, rectangular, or arc-shaped; and the slotted rod is provided with limiting edges on both sides.

[0013] The above-mentioned improvements have the following effects: the cross-section of the drainage channel is V-shaped, which makes it easier to prevent blockage during later construction, and the limiting edge can ensure that the depth of the drainage channel meets the requirements and is not too deep.

[0014] As a further improvement to the above solution, the slotted rod has a two- or multi-section telescopic structure to achieve length adjustment.

[0015] The improved technology allows for adjustment of the drainage channel's length to meet the needs of different locations.

[0016] As a further improvement to the above solution, a rotating seat is provided at the upper end of the positioning seat; the slotted rods are arranged in a ring and hinged on the rotating seat.

[0017] The improved technical effect is that after the slotted rod is installed on the rotating seat, the angle position of the slotted rod can be rotated more conveniently, thus meeting the needs of different positions.

[0018] As a further improvement to the above solution, a rotating cylinder is fitted onto the support rod; the slotted rod is installed at the lower end of the rotating cylinder; and the snap-fit ​​device is installed on the side wall of the rotating cylinder.

[0019] The improved technology has the following effect: it makes it easier to operate the angle of the rotating slotting rod after adopting a rotating cylinder.

[0020] As a further improvement to the above solution, the sidewall of the support rod is provided with movable grooves in a ring shape, corresponding to the number of slotted rods; the movable grooves are opened along the length direction of the support rod; a slider that can slide along the length direction is provided in the movable groove; a connecting rod is hinged between the slider and the corresponding slotted rod; a driving device is provided inside the support rod to drive each slider to move independently; the driving device drives the slider to move towards the handle, thereby driving the slotted rod to retract.

[0021] The improved technology has the following effect: the drive device can quickly retract each slotted bar that has been opened, while the slotted bars that have been retracted are unaffected.

[0022] As a further improvement to the above solution, the driving device is an adjusting shaft that is installed inside the support rod and can move along the length direction; the adjusting shaft extends from the tail end of the support rod and is connected to the handle; a boss is provided at the end of the adjusting shaft; when the adjusting shaft extends from the tail end of the support rod, the boss drives the slider to move towards the handle, thereby driving the slotted rod to retract.

[0023] The improved technology has the following effect: by pulling the handle, the adjusting shaft can be pulled out from the end of the support rod, which will cause the slotted rod that has been opened to retract.

[0024] As a further improvement to the above solution, the driving device is a rotatable threaded shaft installed inside the support rod; the tail end of the threaded shaft extends from the tail end of the support rod and connects to the handle; a threaded sleeve is provided at the end of the threaded shaft; when the adjusting shaft is rotated, the threaded sleeve moves axially along the threaded shaft, driving the slider to move towards the handle, thereby driving the slotted rod to retract.

[0025] The improved technology has the following effect: by rotating the handle, the threaded shaft can drive the opened slotted rod to close up.

[0026] The method for creating a drainage channel using a toilet foamed concrete backfill drainage channel creation device includes the following steps:

[0027] Installation: After the bathroom sunken sump backfill layer is completed, insert the positioning seat into the drain pipe opening, open the side groove rod to separate the groove rod from the support rod, and let the groove rod press on the backfill layer;

[0028] Adjustment: Depending on the location of the drain pipe in the bathroom, open the unobstructed groove rods, and do not open the groove rods that are blocked by the wall; adjust the length of the groove rods according to the required length of the drain groove, until the groove rods are laid radially across the entire backfill layer surface with the drain pipe in the center.

[0029] Grooving: Applying a certain pressure to the grooving rod causes the bottom of the grooving rod to be pressed into the backfill layer, forming a strip groove on the backfill layer; the limiting edges on both sides of the grooving rod limit the grooving depth;

[0030] Demolding: After the backfill layer has solidified, gather the slotted rod and use the clip device to fix the slotted rod to the side of the support rod; then remove the support rod from the drain pipe. Attached Figure Description

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0042] like Figure 1-9 As shown, the specific solution of this embodiment is as follows: a toilet foamed concrete backfill drainage trench opening device, including a support rod 1, a positioning seat 6 for inserting a drainage pipe is provided at the lower end of the support rod 1; the upper edge of the positioning seat 6 is distributed in a ring with slotted rods 3 that can be flipped up and down; the slotted rods 3 are fixed to the side wall of the support rod 1 by corresponding buckle devices.

[0043] A handle 8 is provided at the upper end of the support rod 1.

[0044] Specifically, this device can be made of plastic or lightweight metal; the positioning seat 6 is generally conical or cylindrical, and the support rod 1 will not tip over when the positioning seat 6 is inserted into the drain pipe opening in the bathroom; the conical positioning seat 6 can adapt to the installation of drain pipes with different hole diameters; the slotted rod 3 can be designed according to the size and depth requirements of the drain groove, for example, the slotted rod 3 near the drain pipe opening is higher, and the slotted rod 3 near the drain pipe opening is lower, so that the bottom surface of the drain groove pressed by the slotted rod 3 forms an inclined surface, which facilitates the quick drainage of accumulated water; the buckling device can have various structures, such as a clamping groove 7 opened on the side wall of the support rod 1, and a clamping part 5 set on the slotted rod 3. When the slotted rod 3 is retracted, the clamping part 5 is clamped in the clamping groove 7; the buckling device can also be a structure in which the rod body and the hole cooperate, for example, a hole is opened on the side wall of the support rod 1, and a rod body is set on the slotted rod 3. When the slotted rod 3 is retracted, the rod body is clamped in the hole to form a fixation.

[0045] like Figure 3 As shown, in a preferred embodiment of the above, the cross-section of the slotted rod 3 is V-shaped, rectangular, or arc-shaped; and the slotted rod 3 is provided with limiting edges 31 on both sides.

[0046] The slotted rod 3 has a two- or multi-section telescopic structure, allowing for length adjustment. Specifically, for example... Figure 3 As shown, the slotted rod 3 has an inner slotted rod 4 inside; the slotted rod 3 and the inner slotted rod 4 are interlocked to achieve elongation and shortening; the inner slotted rod 4 has inner limiting edges 41 on both sides; the inner limiting edges 41 are engaged in the grooves formed by the limiting edges 31; the inner limiting edges 41 are used to limit the depth of the inner slotted rod 4 pressed into the backfill layer to ensure that the depth of the drainage groove meets the requirements.

[0047] like Figure 1 As shown, in a preferred embodiment, the upper end of the positioning seat 6 is provided with a rotating seat 2; the slotted rods 3 are arranged in a ring and hinged on the rotating seat 2.

[0048] Specifically, the rotating seat 2 is rotatably mounted on the upper end of the positioning seat 6 and the lower end of the support rod 1; when the rotating seat 2 rotates, it drives all the slotted rods 3 to rotate, thereby adjusting the angular position of the slotted rods 3 in the horizontal plane.

[0049] like Figure 5 As shown, in a preferred embodiment of the above, a rotating cylinder 10 is fitted onto the support rod 1; a slotted rod 3 is installed at the lower end of the rotating cylinder 10; the lower end of the support rod 1 is connected to the positioning seat 6 via a threaded rod 9; and a snap-fit ​​device is installed on the side wall of the rotating cylinder 10.

[0050] Specifically, the rotating cylinder 10 is longer and covers the support rod 1. Compared with the rotating seat 2 structure, this structure makes it easier to operate the rotating slotted rod 3.

[0051] like Figure 6-7As shown, in a preferred embodiment, the sidewall of the support rod 1 has movable grooves 16 distributed in a ring shape, corresponding to the number of slotted rods 3; the movable grooves 16 are opened along the length direction of the support rod 1; a slider 12 that can slide along the length direction is provided in the movable groove 16; a connecting rod 13 is hinged between the slider 12 and the corresponding slotted rod 3; a driving device is provided inside the support rod 1 that can drive each slider 12 to move independently; the driving device drives the slider 12 to move towards the handle 8, thereby driving the slotted rod 3 to retract.

[0052] Specifically, the connecting rod 13 is hinged at one end to the slider 12 via a hinge shaft, and at the other end to the slotted rod 3; this increases the overall strength of the device; when the slotted rod 3 opens, the connecting rod 13 drives the slider 12 to slide downwards in the movable groove 16; when the slotted rod 3 closes, the slider 12 slides upwards in the movable groove 16; the purpose of the driving device is to drive the slider 12 to move linearly in the movable groove 16.

[0053] like Figure 6 As shown, in a preferred embodiment of the above, the driving device is an adjusting shaft 11 that is installed inside the support rod 1 and can move along the length direction; the adjusting shaft 11 extends from the tail end of the support rod 1 and is connected to the handle 8; a boss 17 is provided at the end of the adjusting shaft 11; when the adjusting shaft 11 extends from the tail end of the support rod 1, the boss 17 drives the slider 12 to move towards the handle 8, thereby driving the slotted rod 3 to retract.

[0054] Specifically, the end of the support rod 1 is hollow, and an adjustment shaft 11 is installed inside. The handle 8 is connected to the end of the adjustment shaft 11. When the handle 8 is held and the adjustment shaft 11 is pulled out from the end of the support rod 1, the boss 17 will drive the slider 12 to move, thereby causing the open slotted rod 3 to be retracted.

[0055] like Figure 1 As shown, in a preferred embodiment of the above, the driving device is a rotatable threaded shaft 14 disposed inside the support rod 1; the tail end of the threaded shaft 14 extends out from the tail end of the support rod 1 and is connected to the handle 8; a threaded sleeve 15 is provided at the end of the threaded shaft 14; when the adjusting shaft 11 is rotated, the threaded sleeve 15 moves axially along the threaded shaft 14, driving the slider 12 to move towards the handle 8, thereby driving the slotted rod 3 to retract.

[0056] Specifically, the tail end of the support rod 1 is a hollow structure, with a rotatable threaded shaft 14 installed inside. The handle 8 is connected to the tail end of the threaded shaft 14. When the handle 8 is rotated, the threaded shaft 14 is rotated, so that the threaded sleeve 15 on the threaded shaft 14 can move axially along the threaded shaft 14. However, the threaded sleeve 15 cannot rotate. A spline structure is formed between the threaded sleeve 15 and the inner wall of the support rod 1. By opening a spline groove on the side wall of the threaded sleeve 15, which cooperates with the spline strip on the inner wall of the support rod 1, the rotation of the threaded sleeve 15 can be restricted, ensuring that the threaded sleeve 15 can only move axially along the threaded shaft 14. When the threaded sleeve 15 moves axially, it drives the slider 12 to move in the movable groove 16, thereby driving the slotted rod 3 to retract.

[0057] The method for creating a drainage channel using a toilet foamed concrete backfill drainage channel creation device includes the following steps:

[0058] Installation: After the bathroom sunken sump backfill layer is completed, insert the positioning seat 6 into the drain pipe opening to make the support rod 1 stand up; open the side slotted rod 3 to separate the slotted rod 3 from the support rod 1 and let the slotted rod 3 press on the backfill layer;

[0059] Adjustment: Depending on the location of the drain pipe in the bathroom, open the grooved rod 3 that is not blocked by the wall, and do not open the grooved rod 3 that is blocked by the wall; adjust the length of the grooved rod 3 according to the required length of the drain groove; if the length of the grooved rod 3 is insufficient, the inner grooved rod 4 can be extended until the grooved rod 3 is laid radially across the entire backfill layer surface with the drain pipe in the center.

[0060] Grooving: Apply a certain pressure to the grooving rod 3 so that the bottom of the grooving rod 3 is pressed into the backfill layer, forming a strip groove on the backfill layer; the limiting edges 31 on both sides of the grooving rod 3 limit the grooving depth;

[0061] Demolding: After the backfill layer has solidified, gather the slotted rod 3 and use the clip device to fix the slotted rod 3 to the side of the support rod 1; then remove the support rod 1 from the drain pipe opening. The drainage channels are distributed as follows: Figure 9 As shown.
