Description
Technical Field
[0001] This utility model relates to the field of GRC flooring technology, specifically a combined GRC flooring module. Background Technology
[0002] GRC flooring, or cement flooring, is a type of fiber-reinforced concrete composite flooring made of cement mortar as the matrix material and alkali-resistant glass fiber as the reinforcing material. It is a combination of materials that express creativity through molding, texture, pattern, and color. GRC flooring uses high-quality cement as the main raw material and is reinforced with fiber, which not only ensures the flame retardancy of the raw materials themselves but also enhances the load-bearing capacity of the product.
[0003] Underfloor heating pipes are used in indoor floor heating systems. Low-temperature hot water circulates within the pipes, evenly distributing heat across the entire floor to raise the indoor temperature. Since the pipes are laid beneath the floor, they are highly concealed and do not occupy indoor space. Traditional underfloor heating pipe installation methods require manually creating trenches in the floor and then fixing the pipes inside. However, the depth of manually created trenches is difficult to guarantee, which can affect the flatness of the subsequent flooring installation. This results in time-consuming, labor-intensive, and inefficient installation. Therefore, this method does not meet current needs, and a combined GRC (Glass Reinforced Concrete) overhead module is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a combined GRC overhead module. By setting a first overhead module plate and a second overhead module plate above the indoor ground, and setting metal feet between the first overhead module plate and the ground, the underfloor heating pipes are placed on the first overhead module plate and the second overhead module plate. By adjusting the height of the metal feet, the first overhead module plate and the second overhead module plate can be adjusted to a horizontal state, thereby improving the laying efficiency of the underfloor heating pipes and solving the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined GRC overhead module, including metal feet, a first overhead module plate and a second overhead module plate. Both the first and second overhead module plates have several mounting holes inside. The metal feet are located inside the mounting holes. The first overhead module plate has a first limiting protrusion and a first positioning groove on its top. The second overhead module plate has a second limiting protrusion and a second positioning groove on its top. A floor heating pipe is installed inside the second positioning groove, with one end of the pipe extending into the first positioning groove. Gaskets are provided at the joints of the four first overhead module plates.
[0006] Preferably, both the first and second overhead module panels are rectangular structures, and at least five metal feet are provided below each of the first and second overhead module panels. The gasket has a recessed hole inside, and a positioning screw is provided inside the recessed hole. The lower end of the positioning screw extends into the interior of the mounting hole.
[0007] Preferably, the metal foot includes a rubber sleeve, a sleeve, a tray, a screw, and a base, with the lower end of the screw connected to the base, which is made of rubber.
[0008] Preferably, the rubber sleeve is a hollow cylindrical structure, with a through hole at the upper end and an open lower end, and the rubber sleeve is located inside the mounting hole.
[0009] Preferably, the upper end of the sleeve is located inside the rubber sleeve, and the lower end of the sleeve is connected to the tray.
[0010] Preferably, the upper end of the screw is provided with an internal hexagonal groove, the upper end of the screw is located inside the sleeve, and the screw is threadedly connected to the sleeve.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model involves setting a first and a second overhead module plate above the indoor floor. Metal feet are installed between the first and second overhead module plates and the ground. Underfloor heating pipes are placed on top of the first and second overhead module plates. The first overhead module plate is placed in a large area of the indoor floor, while the second overhead module plate is placed in the area where the underfloor heating pipes are concentrated. By adjusting the height of the metal feet, the first and second overhead module plates can be adjusted to a horizontal state. Compared with the traditional installation method that requires cutting positioning grooves for underfloor heating pipes in the ground, this method avoids the generation of dust and construction waste, thereby improving the laying efficiency of underfloor heating pipes.
[0013] 2. This utility model features several mounting holes inside both the first and second overhead module panels. After inserting the upper end of a sleeve into the rubber sleeve, the rubber sleeve is then inserted into the mounting hole. At this point, the tray is positioned at one end of the mounting hole, while the other end remains open. The operator then rotates a screw into the sleeve. Finally, using a hex wrench, the operator adjusts the screw's position from the other end of the mounting hole until the first and second overhead module panels are level, thus improving the flatness of the subsequent flooring installation. The rubber sleeve and mounting hole are interference-fitted, ensuring the metal feet are firmly fixed inside the mounting hole, thus improving stability. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To address the issues of time-consuming, labor-intensive, and inefficient underfloor heating pipe installation, please refer to [link / reference needed]. Figure 1-10 This utility model provides an embodiment of a combined GRC overhead module, including a metal base 1, a first overhead module plate 2, and a second overhead module plate 3. Both the first overhead module plate 2 and the second overhead module plate 3 have several mounting holes 4 inside. The metal base 1 is located inside the mounting holes 4. The first overhead module plate 2 has a first limiting protrusion 201 and a first positioning groove 202 on its top. The second overhead module plate 3 has a second limiting protrusion 301 and a second positioning groove 302 on its top. A floor heating pipe 5 is installed inside the second positioning groove 302, with one end of the floor heating pipe 5 extending into the first positioning groove 202. Gaskets 6 are installed at the joints of the four first overhead module plates 2.
[0028] Metal feet 1 are located between the first and second overhead module panels 2 and the ground. The first overhead module panel 2 is placed in a large area of the indoor floor, while the second overhead module panel 3 is placed in the area where the underfloor heating pipes 5 are concentrated. By adjusting the height of the metal feet 1, the first and second overhead module panels 2 and 3 can be adjusted to a horizontal state. Compared with the traditional installation method that requires cutting positioning grooves for the underfloor heating pipes 5 in the ground, this method avoids the generation of dust and construction waste, thus achieving simple installation and further improving the laying efficiency of the underfloor heating pipes 5.
[0029] Both the first overhead module panel 2 and the second overhead module panel 3 are rectangular structures. At least five metal feet 1 are provided below each of the first overhead module panel 2 and the second overhead module panel 3. A recessed hole 602 is provided inside the gasket 6, and a positioning screw 601 is provided inside the recessed hole 602. The lower end of the positioning screw 601 extends into the mounting hole 4. Each metal foot 1 includes a rubber sleeve 101, a sleeve 102, a tray 103, a screw 104, and a base 105. The lower end of the screw 104 is connected to the base 105. The base 105 is made of rubber. The rubber sleeve 101 is a hollow cylindrical structure. The upper end of the rubber sleeve 101 is provided with a through hole 1011, and the lower end of the rubber sleeve 101 is in an open state. The rubber sleeve 101 is located inside the mounting hole 4. The upper end of the sleeve 102 is located inside the rubber sleeve 101, and the lower end of the sleeve 102 is connected to the tray 103. The upper end of the screw 104 is provided with an internal hexagonal groove 1041, and the upper end of the screw 104 is located inside the sleeve 102. The screw 104 and the sleeve 102 are threadedly connected.
[0030] After inserting the upper end of the sleeve 102 into the rubber sleeve 101, the operator then inserts the rubber sleeve 101 into the mounting hole 4. At this point, the tray 103 is located at one end of the mounting hole 4, while the other end of the mounting hole 4 is open. The operator then rotates the screw 104 into the sleeve 102. Finally, the operator uses a hex wrench to adjust the position of the screw 104 from the other end of the mounting hole 4 until the first and second overhead module panels 2 and 3 are level, thus improving the flatness of the subsequent floor installation. The rubber sleeve 101 and the mounting hole 4 have an interference fit, ensuring the metal... The foot 1 can be firmly fixed inside the mounting hole 4, improving stability. At the same time, a gasket 6 is set at the splicing point of the four first overhead module panels. Each gasket 6 has four positioning screws 601 inside. The positioning screws 601 pass through the recessed hole 602 into the inside of the mounting hole 4 and then extend into the inside of the sleeve 102. The positioning screws 601 are threadedly connected to the sleeve 102. The four positioning screws 601 are respectively fixed inside the four mounting holes 4 below the gasket 6, ensuring the stability of the first overhead module panels after splicing and further improving the stability of the underfloor heating pipes 5 after installation.
[0031] Working principle: After fixing the metal feet 1 inside the mounting holes 4 of the first and second overhead module panels 2 and 3, the operator uses a hex wrench to adjust the position of the screw 104 until the first and second overhead module panels 2 and 3 are horizontal. Then, the metal feet 1 support the first and second overhead module panels 2 and 3 on the ground. Finally, the underfloor heating pipe 5 is placed inside the second positioning groove 302. One end of the underfloor heating pipe 5 is connected to the manifold, and the other end extends into the first positioning groove 202. Compared with the traditional installation method that requires cutting positioning grooves for the underfloor heating pipe 5 in the ground, this method avoids the generation of dust and construction waste, thus achieving simple installation and improving the laying efficiency of the underfloor heating pipe 5.
