Description

Technical Field

[0001] This invention relates to the field of building construction technology, and to a device for pre-reserving grooves for water supply pipes in bathrooms and its construction method. Background Technology

[0002] Currently, after the initial pouring of the bathroom curb, the water supply pipe trenching is typically completed using methods such as cutting and chiseling, pre-embedding PVC pipes, or fixing the trench with aluminum formwork, depending on the location of the water supply pipe. Cutting and chiseling involves mechanical cutting and grooving after the concrete has cured and the wall has been constructed. The width, depth, verticality, and flatness of the trench must meet the requirements for pre-embedding the pipe. Before pre-embedding the water supply pipe, the trench and its surrounding area are cleaned. After pre-embedding, cement mortar is used for sealing, leveling, and curing to achieve the purpose of pre-embedding the water supply pipe. Pre-embedding PVC pipes involves selecting appropriate pipe materials based on the width and depth of the trench, cutting them into semi-circular shapes, and fixing them to the formwork with tape or nails according to the location and width requirements of the water supply pipe. The pipes are removed along with the formwork after the concrete has cured. Fixing the pre-embedded parts with aluminum formwork involves directly fixing the finished semi-circular pre-embedded parts to the side plate of the aluminum formwork with screws according to the location of the water supply pipe. These are also removed along with the aluminum formwork after the concrete has cured. The above methods all have some drawbacks: 1) The cutting and chiseling method requires cutting and chiseling the finished concrete upturned sill, which is labor-intensive and wasteful of materials. The chiseling process damages the finished product, disturbs the strength of the upturned sill, and easily causes cracks, reduces the self-waterproofing effect, and reduces the strength; 2) The pre-embedded PVC pipe method uses tape or iron to fix the semi-circular plastic pipe to the template. Because the PVC pipe is not rigid enough, it is easy to deform during construction. The pre-embedded spacing and verticality are inaccurate and the deviation is large, resulting in poor grooving effect; 3) The aluminum film fixing grooving method uses multiple screws to fix the aluminum film to the side. It is easy to leave marks during turnover. Moreover, the grooving device is independent and the installation time and verticality are prone to excessive variation.

[0003] Therefore, developing a toilet backsplash water pipe groove structure that is easy to construct, has a good groove pressing effect, and is low in cost is of great practical significance. Summary of the Invention

[0004] Due to the aforementioned defects in the existing technology, the present invention provides a toilet backsplash water supply pipe grooving structure that is convenient to construct, has a good grooving effect, and is low in cost. It overcomes the defects of the existing toilet backsplash water supply pipe grooving structure, such as poor grooving effect, low construction accuracy, poor durability, cumbersome construction, and high construction cost.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A device for pre-reserving grooves for water supply pipes on a bathroom curb includes a side template, a groove plate, and a fixing pin.

[0007] The side wall of the side template has multiple side template pin holes;

[0008] The grooving plate includes a grooving fixing plate and at least two grooving columns. The grooving fixing plate has at least two grooving fixing plate pin holes, which are located on both sides of the grooving fixing plate. The grooving columns are fixedly connected to the grooving fixing plate, and the axial direction of the grooving columns is perpendicular to the grooving fixing plate. The multiple grooving columns are arranged at intervals.

[0009] The fixing pins pass through the pin holes of the pressing plate and the pin holes of the side template in sequence to fix the pressing plate to the side template.

[0010] The present invention relates to a device for pre-grooving water supply pipes in bathrooms with a reasonable structural design. Multiple grooving columns are installed on a grooving plate, and the grooving spacing can be controlled by adjusting the spacing of the columns. Since the columns are fixed to the grooving fixing plate, large grooving spacing errors are avoided. Installation is completed by fixing the grooving plate to the side template, making construction convenient. Simply attaching the grooving fixing plate to the side template ensures the columns are vertical, resulting in good grooving effect. Compared to existing technologies, its construction cost is low, and its application prospects are promising.

[0011] As a preferred technical solution:

[0012] As described above, a device for pre-reserving grooves for water supply pipes in a bathroom is provided, wherein the side template is an aluminum film plate and the top of the aluminum film plate extends outward along a direction perpendicular to the film plate, and the pin holes of the side template are located on the fixed edge.

[0013] As described above, a device for pre-reserving grooves for water supply pipes in bathrooms has a row of side template pin holes arranged equidistantly along the length of the fixed edge. Those skilled in the art can adjust the installation position of the groove plate according to actual needs.

[0014] As described above, a device for pre-reserving grooves for water supply pipes in bathrooms with inverted curbs is provided, wherein the groove column is a semi-cylindrical structure and its tangential direction is connected to the groove fixing plate.

[0015] As described above, a device for pre-reserving grooves for water supply pipes in bathrooms with anti-recessed curbs is provided in which multiple reinforcing ribs are provided inside the groove column, perpendicular to the axis of symmetry of the groove column, and the multiple reinforcing ribs are arranged at equal intervals. The reinforcing ribs enhance the bending capacity of the groove column, making it less prone to deformation, so as to avoid deformation of the groove column under the action of concrete.

[0016] The reinforcing rib of the groove column furthest from the groove fixing plate is flush with the bottom of the embedded part.

[0017] As described above, a device for pre-reserving grooves for water supply pipes in bathrooms with a backsplash has two groove-reserving columns fixed on the groove-reserving plate, with the two groove-reserving columns located on both sides of the groove-reserving plate.

[0018] As described above, in a device for pre-reserving grooves for water supply pipes on a bathroom curb, the height of the groove support column is equal to the height of the curb.

[0019] Furthermore, the present invention also provides a construction method for a pre-reserved device for a water supply pipe groove in a bathroom, as described above, comprising the following steps:

[0020] (1) Process the edge template and groove plate. The height of the grooved column on the groove plate is equal to the height of the inverted curb.

[0021] (2) Install the edge template;

[0022] (3) Use fixing pins to fix the groove plate to the side template;

[0023] (4) Pour concrete into the formwork;

[0024] (5) After the concrete has solidified, demold the concrete and remove the groove plate from the side formwork. The above method is simple to operate, has high construction efficiency, and can be effectively recycled for use in the pre-reserved device for the groove of the water supply pipe of the bathroom back slope, reducing construction costs and showing good application prospects.

[0025] The above technical solution is only one feasible technical solution of the present invention. The scope of protection of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

Multiple groove columns are set on a groove plate. The groove spacing can be controlled by controlling the spacing of the groove columns. Since the groove columns are fixed to the groove fixing plate, there will be no problem of large groove spacing error.

[0038] A row of side template pin holes 11 are opened on the fixed edge, arranged at equal intervals along the length of the fixed edge;

[0039] The grooved plate 2 includes a grooved fixing plate 21 and two grooved columns 23 arranged at intervals (the height of the grooved columns 23 is equal to the height of the countersunk). The two grooved columns 23 are located on both sides of the grooved fixing plate 21. The grooved fixing plate 21 has two grooved fixing plate pin holes 22, which are located on both sides of the grooved fixing plate 21. The grooved columns 23 are semi-cylindrical structures and their cross-sections are fixedly connected to the grooved fixing plate 21. The axial direction of the grooved columns 23 is perpendicular to the grooved fixing plate 21. The grooved columns 23 are provided with multiple grooved column reinforcing ribs 24 that are perpendicular to the axis of symmetry of the grooved columns 23 and are arranged at equal intervals. The grooved column reinforcing rib 24 farthest from the grooved fixing plate 21 is flush with the bottom of the embedded part.

[0040] The fixing pin 3 passes through the pin hole 22 of the pressing plate and the pin hole 11 of the side template in sequence to fix the pressing plate to the side template 1.

[0041] Specifically, the specifications of the fixing pin are: a solid truncated cone with a diameter of φ8mm at the bottom and φ15mm at the top, made of Q235 galvanized steel, and a length of 50mm;

[0042] The total length of the groove fixing plate is 250mm and the width is 50mm. It consists of a 50mm diameter semi-circular steel plate on each side and a thickness of 3mm. It is designed as an integral part of the groove fixing column. The pin holes of the groove fixing plate are φ10mm in diameter and φ11mm in diameter frustum pin holes at the top. The distance between the pin holes of the two groove fixing plates is 200mm. The groove fixing column is a φ50mm*2mm semi-circular column with the same length as the concrete upturned curb (customizable). The general length is 200mm or 300mm. The reinforcing ribs of the groove fixing column are φ48mm*2mm. Each groove fixing column is equipped with 3 reinforcing ribs. The bottom reinforcing rib is flush with the bottom of the column, and the two middle reinforcing ribs are evenly distributed according to the length of the embedded parts.

[0043] The aluminum formwork panel is the same height as the concrete ramp (customizable), 3.5mm thick, and has a 50mm fixed edge with a pin hole every 50mm.

[0045] (1) Process the edge template and groove plate. The height of the grooved column on the groove plate is equal to the height of the inverted curb.

[0046] (2) Install the edge template;

[0047] (3) Use fixing pins to fix the groove plate to the side template. Specifically, fasten the groove fixing plate on the fixing edge of the aluminum film plate so that the pin hole of the groove fixing plate coincides with the pin hole of the aluminum film plate. After the pin hole of the groove fixing plate is aligned, insert the fixing pin and use a hammer to fix it firmly.

[0048] (4) Pour concrete into the formwork;

[0049] (5) After the concrete has solidified, demold and remove the groove plate from the side formwork.

[0050] Verification has shown that the pre-grooving device for water supply pipes on bathroom backsplashes of this invention has a reasonable structural design. Multiple grooving columns are set on a grooving plate, and the grooving spacing can be controlled by adjusting the spacing of the columns. Since the columns are fixed to the fixing plate, large grooving spacing errors are avoided. Installation is completed by fixing the grooving plate to the side template, making construction convenient. Fitting the fixing plate to the side template ensures the columns are vertical, resulting in good grooving effect. The construction method is simple, efficient, and recyclable, reducing construction costs and showing promising application prospects.
