Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary tools for building decoration construction, and specifically to an auxiliary installation tool for controlling the slope of floor drains. Background Technology
[0002] In floor drain installation, whether it's pre-installation during the civil engineering phase or post-installation during the decoration phase, controlling the drainage slope still heavily relies on the personal experience of construction workers, who generally rely on visual inspection or simple tools to roughly find the slope. Due to the lack of an integrated, standardized tool to provide a unified installation benchmark, this method is not only inefficient but also struggles to guarantee consistent construction quality, easily leading to serious defects such as insufficient slope or even reverse slope, resulting in problems like poor drainage and water accumulation on the floor. Furthermore, this practice results in messy and unsightly floor drain installations in non-tiled areas; while in tiled areas, the cutting and joining of the floor drain with the tiles is difficult to ensure a perfect fit, affecting the overall decoration effect. Therefore, there is an urgent need for an auxiliary installation tool that can simultaneously achieve precise positioning, rapid leveling, and standardized slope formation. Utility Model Content

The side of the slope plate away from the positioning frame is inclined toward the bottom of the geometric center of the positioning frame.
[0005] As an optimization of the auxiliary installation tool for controlling the slope of floor drains, the slope of the slope plate is 2%-3%.
[0006] As an optimization of the auxiliary installation tool for controlling the slope of floor drains, the slope plate is provided with at least one pouring hole.
[0007] As an optimization of the auxiliary installation tool for controlling the slope of the floor drain, the bottom surface of the slope plate is provided with a pouring groove extending downward from the pouring hole along the slope.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail below.
[0017] This application provides an auxiliary installation tool for controlling the slope of a floor drain, employing the following technical solution: Reference Figure 1 and Figure 2The auxiliary installation tool for controlling the slope of the floor drain includes a positioning frame 1 and slope plates 2. The positioning frame 1 is a square frame with a hollow geometric center, preferably made of engineering plastics such as nylon or polypropylene through injection molding, which has the advantages of being lightweight, corrosion-resistant, and not easily adhered to concrete. Multiple pre-embedded fixing holes 11 are provided on the periphery of the positioning frame 1 for installing bolts. The height of the entire tool can be precisely adjusted and fixed by tightening the bolts, so that its upper surface is flush with the final concrete or tile finish. In this embodiment, a pre-embedded fixing hole 11 is provided at each of the four corners of the positioning frame 1. The hollow area inside the positioning frame 1 is square, and slots 12 are provided on all four sides of the inner sidewall of the positioning frame 1. Four slope plates 2 are provided, each corresponding to one sidewall of the positioning frame 1. The outer periphery of the slope plate 2 protrudes outward to form a protrusion 21 that matches the shape of the slot 12. The protrusion 21 is installed in the slot 12, realizing a detachable connection between the slope plate 2 and the positioning frame 1. Specifically, in this embodiment, each side wall of the positioning frame 1 has two symmetrically formed slots 12, and each slope plate 2 has two corresponding protrusions 21, which are paired with the slots 12. When the slope plate 2 is detachably installed on the positioning frame 1, the side of the slope plate 2 away from the positioning frame 1 is inclined towards the bottom of the geometric center of the positioning frame 1, thereby forming a continuous conical drainage surface when the floor drain is installed. Preferably, the slope of the slope plate 2 is 2%-3%, which meets the standard requirements for building drainage slope and can effectively ensure smooth drainage of the floor drain, avoiding water accumulation or backslope.
[0018] In practical applications, after leveling and fixing the positioning frame 1 through the pre-embedded fixing holes 11, the sloped plate 2 is installed to form a robust, shaped cavity with a standard inclined conical surface. Placing the floor drain in the center of this cavity for subsequent construction ensures that its final installation height is flush with the surrounding finished surface, and that a uniform and accurate drainage slope is formed around it. The installation tool of the above structure replaces the traditional experience-based construction method, providing a reliable physical benchmark for floor drain installation, thereby ensuring the uniformity of installation quality, the reliability of drainage function, and the aesthetics of the finished surface.
[0019] In the preferred embodiment of this application, reference is made to Figure 2 and Figure 3 Each sloping slab 2 has at least one pouring hole 22. The pouring hole 22 is used as an inlet for pouring fine stone concrete or mortar when the hole is opened later for installation, thereby forming a sloping filling layer in the formwork.
[0020] Furthermore, referring to Figure 2 and Figure 3The bottom surface of the slope plate 2 is provided with a pouring groove 23. The pouring groove 23 starts from the pouring hole 22 and extends downward along the slope of the slope plate 2 until its inner edge. Its function is to guide the concrete to flow to the central area during pouring and to help to expel the air in the cavity, so as to ensure that the pouring is dense and without voids.
[0021] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2 The top surface of the positioning frame 1 is slidably equipped with a limiting rod 14. Two fixing rings 13 are fixedly welded in parallel on the positioning frame 1. The two fixing rings 13 are located on both sides of the slot 12. The limiting rod 14 is specifically configured to slide through the fixing rings 13. When the limiting rod 14 is pushed to slide above the slot of the slot 12, the rod body of the limiting rod 14 is horizontal in the movement path of the protrusion 21, forming an effective mechanical block to prevent the protrusion 21 from falling out of the slot 12 due to accidental collision or vibration, which greatly improves the stability and reliability of the tool during construction.
[0022] The application process and implementation principle of this application are as follows: In the scenario of the civil engineering pre-reservation stage, the installation tool is directly embedded as a mold, and after pouring, it forms a pre-reserved hole with an accurate slope; in the scenario of post-opening in the decoration stage, the tool and the hanging formwork base plate form a closed cavity, and concrete is poured through the pouring hole 22 and pouring groove 23 on the slope plate 2 to form a dense slope base; in the scenario of the tiling area, the installation tool serves as a calibration benchmark for height and slope, and ensures that the tiles around the floor drain are flush with the finished surface by pressing down. The installation tool provided by this application realizes the functions of positioning, leveling, and slope forming in the construction process through a concrete and reusable physical tool, eliminating quality fluctuations caused by human factors and significantly improving construction efficiency and quality consistency.
[0023] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
