Description

Technical Field

[0001] This utility model relates to the field of bathroom construction technology, specifically to a positioning device for the construction of a waterproof additional layer for bathroom pipe roots. Background Technology

[0002] In the construction industry, bathroom waterproofing is a crucial step in ensuring the functionality and durability of a building, but it is also an area prone to quality problems. Traditional bathroom waterproofing involves first installing a mortar waterproofing leveling layer to ensure a smooth base for subsequent waterproofing layers. However, this process has significant drawbacks: the leveling layer and structural layer are prone to cracking and delamination due to poor adhesion and material shrinkage, leading to tearing of the waterproofing membrane and causing leaks. Such leaks not only affect normal use but also increase repair costs during the building's warranty period, becoming a core quality pain point for construction companies. Taking areas like pipe roots and corners in the bathroom as examples, these are weak points in waterproofing and require an additional waterproofing layer to enhance the effect. Relevant construction standards clearly require that the additional layer extend at least 250mm outwards.

[0003] However, in existing construction processes, pipe root positioning often relies on manual visual inspection or simple tools, making it difficult to accurately center and fix pipe roots of different diameters. This can easily lead to deviations in the application area of ​​the additional layer due to positioning errors. At the same time, there is a lack of unified and precise indicators for determining the boundary of the additional layer coating. Construction workers often operate based on experience, resulting in insufficient or excessive coating width. This wastes waterproofing materials, fails to guarantee the quality of waterproofing at joints, and further exacerbates the risk of leakage in bathrooms. Therefore, those skilled in the art provide a bathroom pipe root waterproofing additional layer construction positioning device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for the construction of a waterproof additional layer for bathroom pipe roots, thereby solving the problems mentioned in the background art of the prior art.

[0005] This utility model provides the following technical solution: a positioning device for waterproof additional layer construction of bathroom pipe roots, including a base and an annular groove. The upper end of the base is provided with a positioning component for centering and fixing the pipe root. The outer side wall of the base is evenly distributed with four measuring components for indicating the coating range of the additional layer around the pipe root.

[0006] As a preferred embodiment of the above technical solution, the positioning component includes an inner frame post, which is slidably fitted inside the base. An annular protrusion is fixedly connected to the outer side wall of the inner frame post, and the annular protrusion is slidably engaged with the inner side of the annular groove.

[0007] As a preferred embodiment of the above technical solution, three fixed columns are evenly distributed at the upper edge of the inner frame column. The upper ends of the three fixed columns are fixedly connected to a ring plate, and the lower ends of the ring plate are rotatably sleeved with three fixed shafts. The lower ends of the three fixed shafts are all fixedly connected to a sliding sleeve.

[0008] As a preferred embodiment of the above technical solution, the upper end of the base is fixedly connected with three fixed shafts in a ring arrangement, the upper ends of the three fixed shafts are fixedly connected with positioning rods, and the lower ends of the three positioning rods away from the three fixed shafts are fixedly connected with positioning wheels.

[0009] As a preferred embodiment of the above technical solution, a fixing plate is fixedly connected to the upper edge of the base, a motor is fixedly connected to the center of one end of the fixing plate, a stud is fixedly connected to the output end of the motor, a sliding sleeve is threaded on the outer side of the stud, and a driving protrusion is fixedly connected to the lower end of the sliding sleeve.

[0010] As a preferred embodiment of the above technical solution, the measuring component includes a measuring frame, which is fixedly connected to the upper side wall of the base. A limit post is symmetrically fixedly connected to the inner end of the measuring frame away from the base. A rack is fixedly connected to the two inner walls of the measuring frame that are close to each other.

[0011] As a preferred embodiment of the above technical solution, a second measuring frame is slidably fitted inside the first measuring frame. A locking block is symmetrically fixedly connected to one end of the second measuring frame near the base. A fixed shaft three is symmetrically rotatably fitted inside the second measuring frame near the base. Gears are fixedly connected to the outer sides of both fixed shafts three. A rack two is meshed and connected between the two gears. A limit post two is fixedly connected to one end of the rack two near the base. A third measuring frame is fixedly connected to one end of the rack two away from the base. A bright marking strip is fixedly connected to the upper end of the third measuring frame away from the rack two.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In use, the positioning device of this utility model first places the base on the outside of the pipe root. The motor is started, and the motor output shaft drives the stud to rotate. Since the stud and the sliding sleeve are threadedly connected, the sliding sleeve moves up and down along the stud. The driving convex plate at the lower end of the sliding sleeve moves accordingly, pushing the inner frame column to slide up and down inside the base. The annular convex post on the outer side of the inner frame column moves along the annular groove of the base, ensuring the stability of the inner frame column's movement. The upper end of the inner frame column is connected to a ring plate via three fixed posts, and the lower end of the ring plate has three fixed shafts connected to a sliding sleeve. When the inner frame column is driven to move up and down, the ring plate moves accordingly, thereby driving the three positioning connecting rods to rotate around the fixed shafts. The positioning wheel at the lower end of the positioning connecting rods always maintains rolling contact with the outer wall of the pipe root, automatically adapting to the pipe diameter during adjustment, achieving centering and clamping fixation of the pipe root within the device.

[0014] Based on the aforementioned beneficial effects, before applying the waterproof additional layer, the coating area needs to be determined. The operator pulls the measuring frame three outwards, which in turn moves the rack two outwards. The rack two meshes with two gears, driving them to rotate. The gears are fixed to a fixed shaft three, which in turn drives the measuring frame two to extend outwards synchronously from inside the measuring frame one. A bright marking strip at the top of the measuring frame three clearly indicates the coating boundary. This transmission mechanism ensures that the marking strip is precisely positioned 250mm from the outer wall of the pipe root, allowing the construction personnel to apply the coating accordingly, thus ensuring the standardization and consistency of the additional layer application.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1 As shown, this utility model provides a technical solution: a positioning device for waterproof additional layer construction of bathroom pipe roots, including a base 1 and an annular groove 11. The upper end of the base 1 is provided with a positioning component 2 for centering and fixing the pipe root. The outer side wall of the base 1 is evenly distributed with four measuring components 3 for indicating the coating range of the additional layer around the pipe root.

[0022] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, the positioning component 2 includes an inner frame post 21, which is slidably sleeved inside the base 1. An annular protrusion post 22 is fixedly connected around the outer wall of the inner frame post 21, and the annular protrusion post 22 is slidably engaged with the inner side of the annular groove 11.

[0023] The positioning component 2 slides inside the base 1 via the inner frame column 21, and achieves stable alignment through the cooperation of the annular protrusion 22 and the annular groove 11, ensuring that the pipe root remains in the center position during construction, which facilitates the accurate application of the subsequent waterproof additional layer.

[0024] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, three fixed posts 23 are evenly distributed at the upper edge of the inner frame post 21. The upper ends of the three fixed posts 23 are fixedly connected to a ring plate 24. The lower ends of the ring plate 24 are rotatably fitted with three fixed shafts 25. The lower ends of the three fixed shafts 25 are all fixedly connected to a sliding sleeve 26.

[0025] The upper end of the inner frame column 21 is connected to the ring plate 24 by three fixed columns 23. The fixed shaft 25 and sliding sleeve 26 structure set below the ring plate 24 can provide the necessary flexible adjustment space during pipe root installation, adapt to different pipe diameters and provide a fixing function, thereby enhancing the applicability and stability of the device.

[0026] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, three fixed shafts 27 are fixedly connected in a ring at the upper end of the base 1. Positioning rods 28 are fixedly connected to the upper ends of the three fixed shafts 27. Positioning wheels 29 are fixedly connected to the lower ends of the three positioning rods 28 away from the three fixed shafts 27.

[0027] The three fixed shafts 27 arranged in a ring on the upper end of the base 1, along with the positioning connecting rod 28 and the positioning wheel 29, can form uniform support and positioning points around the pipe root. The rolling contact of the positioning wheel 29 reduces friction, making it easier to install and adjust the device on the pipe root and improving construction efficiency.

[0028] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, a fixing plate 210 is fixedly connected to the upper edge of the base 1. A motor 211 is fixedly connected to the center of one end of the fixing plate 210. A stud 212 is fixedly connected to the output end of the motor 211. A sliding sleeve 213 is threaded on the outer side of the stud 212. A driving protrusion 214 is fixedly connected to the lower end of the sliding sleeve 213.

[0029] The motor 211 on the fixed plate 210 drives the stud 212 to rotate, which in turn drives the sliding sleeve 213 and the protruding plate 214 to move up and down, thereby adjusting the position of the inner frame column 21, ensuring the accurate positioning of the pipe root in the vertical direction, and driving the movement of the positioning connecting rod 28 and the positioning wheel 29, enhancing the automatic adjustment capability and ease of operation of the overall device.

[0030] As one implementation method in this embodiment, please refer to Figure 4 As shown, the measuring component 3 includes a measuring frame 31, which is fixedly connected to the upper side wall of the base 1. A limit post 32 is symmetrically fixedly connected to the inner end of the measuring frame 31 away from the base 1. A rack 33 is fixedly connected to the two inner walls of the measuring frame 31 that are close to each other.

[0031] The measuring frame ruler 31 in measuring component 3, through the structure of the limiting post 32 and the rack 33, provides guidance and limitation for the extension and retraction of the subsequent measuring frame ruler 34, ensuring stability and accuracy in the measurement process and providing a reliable basis for the coating range of the waterproof additional layer.

[0032] As one implementation method in this embodiment, please refer to Figure 4As shown, a second measuring frame 34 is slidably fitted inside the measuring frame ruler 1 31. A locking block 35 is symmetrically fixedly connected to one end of the measuring frame ruler 2 34 near the base 1. A fixed shaft 36 is symmetrically rotated inside the measuring frame ruler 2 34 near the base 1. Gears 37 are fixedly connected to the outer sides of both fixed shafts 36. A rack 2 38 is meshed and connected between the two gears 37. A limit post 2 39 is fixedly connected to one end of the rack 2 38 near the base 1. A measuring frame ruler 310 is fixedly connected to the end of the rack 2 38 away from the base 1. A bright marking strip 311 is fixedly connected to the upper end of the measuring frame ruler 310 away from the rack 2 38.

[0033] The operator pulls the measuring frame ruler 310 to extend it, which in turn drives the measuring frame ruler 34 to move outward through the transmission of rack 2 38 and gear 37. The high-brightness marking strip 311 on it can clearly indicate the coating boundary. The high-brightness marking strip 311 can indicate the position where the measurement value is 250mm, which is convenient for construction personnel to quickly identify and operate, thus improving construction accuracy and efficiency.

[0034] Working Principle: When using this positioning device, the base 1 is first placed over the outside of the pipe root. The motor 211 is started, and its output shaft drives the stud 212 to rotate. Since the stud 212 and the sliding sleeve 213 are threadedly connected, the sliding sleeve 213 moves up and down along the stud 212. The driving convex plate 214 at the lower end of the sliding sleeve 213 moves accordingly, pushing the inner frame column 21 to slide up and down inside the base 1. The annular convex column 22 on the outer side of the inner frame column 21 moves along the annular groove 11 of the base 1, ensuring the stability of the inner frame column 21's movement. The upper end of the inner frame column 21 is connected to the ring plate 24 via three fixed columns 23, and the lower end of the ring plate 24 has three fixed shafts 25 connected to a sliding sleeve 26. When the inner frame column 21 is driven to move up and down, the ring plate 24 moves accordingly, thereby driving the three positioning connecting rods 28 to rotate around the fixed shaft 27. The positioning wheel 29 at the lower end of the positioning link 28 always maintains rolling contact with the outer wall of the pipe root, automatically adapting to the pipe diameter during the adjustment process, and realizing the centering and clamping fixation of the pipe root in the device.

[0035] Before applying the additional waterproof layer, the coating area must be determined. The operator pulls the measuring frame 310 outwards, causing the rack 38 to move outwards. The rack 38 meshes with two gears 37, driving them to rotate. The gears 37 are fixed to a fixed shaft, which in turn drives the measuring frame 34 to extend outwards synchronously from inside the measuring frame 31. The high-gloss marking strip 311 at the top of the measuring frame 310 clearly indicates the coating boundary. This transmission mechanism ensures the marking strip is precisely positioned 250mm from the outer wall of the pipe root, allowing the operator to apply the coating correctly and ensuring the standardization and consistency of the additional layer application.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
