Description

[0001] This application is a divisional application of the Chinese patent application with application number 202080086911.4, application date December 14, 2020, and invention name "Concave-convex metal plate and floor heating system using the metal plate". Technical Field

[0002] The present invention relates to a concave-convex metal plate and a floor heating system using the same, and more particularly to a concave-convex metal plate which is easy to install on the ground, accommodates heating elements such as heating pipes or electric heating cables, and improves load-bearing resistance by repeatedly forming recessed portions and raised portions, thereby being used as a plate-like structural material, and a floor heating system using the same. Background Art

[0003] Generally speaking, when heating the floor, various materials are attached or laminated to the floor. Depending on the method of fixing the materials to the floor, there are two types of construction methods: wet construction method and dry construction method. Figure 1 and Figure 2 Each shows an example of a dry construction method and a wet construction method.

[0004] like Figure 1 As shown, the dry construction method is to lay thermal insulation material 202 on the decorated floor 201, set heating film 203 and stick protective plate 204, and finally install decorative materials 205 such as decorative tiles. The method only uses the construction method of heating film and kang board to stack the flat films and plates in sequence according to the functions of the materials.

[0005] like Figure 2 As shown, the wet construction method is to solidify the air bubble concrete 302 with a thickness of about 50 mm on the floor slab 301, set the electric heating pipe 303 for heating thereon, and then solidify the mortar 304 with a thickness of about 30-40 mm, and finally decorate with the decorative material 305. After the electric heating pipe 303 for heating, which is a round or long cross-linked polyethylene pipe, metal pipe, cable, etc., is set, it is permanently fixed with cement mortar.

[0006] The heating materials used in the dry construction method are mainly in the form of plates, while the heating materials used in the wet construction method are in the form of heating pipes. Figure 1 As shown, the dry construction method combines and laminates the heating materials in board form on the ground according to their functions to make installation and removal easy. Figure 2 As shown, the wet construction method uses cement mortar for permanent fixation, which makes installation and disassembly more complicated.

[0007] Figure 3 This is a cross-sectional view showing an example of a wet construction method. As shown in the figure, a heating pipe 40 is installed on a heat insulating material 10, and is decorated with a decorative material 60 such as a decorative tile, a floor or a floor glue in a state filled with mortar (70).

[0008] The present invention uses a dry construction method to construct heaters that were originally constructed using a wet construction method, such as round or long cross-linked polyethylene pipes, metal pipes, cables and other heating materials. The heaters are easy to install and disassemble, have a long and safe life, short construction time, are light and low in height, and can improve many problems of wet construction. Summary of the invention

[0009] Problem that the invention aims to solve

[0010] Figure 5 This is a schematic diagram showing an example of a dry construction method that has been tried in some cases recently. When a heating material such as a round or long cross-linked polyethylene pipe, metal pipe, cable, etc. that was originally constructed using a wet construction method is constructed using a dry construction method, Figure 5 As shown, a frame is made of a heat insulating material 10 such as synthetic resin or foamed polystyrene and attached to the ground, and a heating pipe 40 such as a round heater such as a cross-linked polyethylene tube is inserted and installed on the frame.

[0011] The dry construction method has the following problems:

[0012] First, since the frame is made of heat insulating materials 10 such as synthetic resin and foamed polystyrene, it is difficult to bear the weight and shrinks and deforms, causing the ground to sink.

[0013] Second, the life of synthetic resin insulation materials is as short as about five years when simply laminated. It is difficult to achieve semi-permanent life of more than 30 years.

[0014] Third, in Figure 5 In the embodiment, since the bottom surface and two side surfaces of the heating pipe 40 are surrounded by the heat insulating material 10, the heat is diffused only upwards, so that the heat diffusion efficiency is very low compared with the existing cement mortar surrounding the entire heating pipe.

[0015] If the heat diffusion efficiency is low, after the hot water supplied to a residence such as an apartment through a heating pipe 40 such as a cross-linked polyethylene pipe flows into the interior of the residence, it cannot enter the interior of the residence during the flow time and simply passes through, thereby using more hot water and generating more hot water usage fees. Therefore, this method has not been popularized in apartments, etc.

[0016] So far, heaters in the shape of round or long cross-linked polyethylene pipes, metal pipes, cables and other heating materials can only be constructed using cement mortar wet construction methods. There are four reasons for this:

[0017] First, Figure 4As shown, when a heating pipe 40 such as an electric heater is installed on the insulating material 10, a space is generated between the heaters, so all the weight pressed down by the decorative material 60 above presses down the heater, and there is no better material than cement that can withstand this weight.

[0018] Second, it needs to have good thermal conductivity so that the heat from the heating pipe can be transferred to the room as quickly as possible, and there is no material with better thermal conductivity than cement.

[0019] Third, there is no better material than cement to achieve a service life of more than 30 years after installation.

[0020] Fourth, as a method that is widely known, easy to understand, simple, can be constructed by everyone, and has relatively low construction costs, there is no better method than cement mortar construction.

[0021] The object of the present invention is to develop a material and a construction method having functions superior to the characteristics of the cement mortar, thereby providing a floor heating system that can take advantage of the advantages of the wet construction method while retaining the advantages of the dry construction method.

[0022] Solutions to the problem

[0023] In order to solve the above problems, the floor heating system of the present invention processes the metal plate, which has a thermal conductivity and destructive strength about five times higher than that of cement, into a shape suitable for the floor heating structure.

[0024] Specifically, the metal plate is a concave-convex metal plate, which is repeatedly bent to form concave parts and convex parts to transfer the weight from the upper part of the decorative material to the floor panel; the concave part is formed to be large enough to accommodate the linear heating element while being in contact with the linear heating element at the bottom and left and right sides.

[0025] Either the lower portion of the recessed portion or the upper portion of the raised portion has a flat surface; the recessed portion may also be formed in an arc shape so as to contact the lower portions of the left and right side surfaces of the linear heating element.

[0026] The concave and convex parts of the concave-convex metal plate may be formed in one direction or in two directions.

[0027] In addition, the concave-convex metal plate is formed of a material selected from iron plate, color steel plate, synthetic resin coated plate, zinc electroplated plate, aluminum-zinc alloy steel plate, galvanized steel plate, tin electroplated steel plate, aluminum, duralumin, aluminum alloy plate, copper plate, brass, and bronze.

[0028] The concave-convex metal plate is formed by one of gear forming, rolling forming and stamping forming.

[0029] According to the floor heating system of the present invention, it includes: an insulating material, which prevents heat from the heating element from being transferred to the floor slab direction; a lower heat diffusion plate, which is located on the upper part of the insulating material and transfers the heat conducted from the heating element to the horizontal direction; a concave-convex metal plate, which is located on the upper part of the lower heat diffusion plate and accommodates the heating element; the heating element is accommodated in the concave part of the concave-convex metal plate; and an upper heat diffusion plate, which is located on the upper part of the concave-convex metal plate and transfers the heat conducted from the legal body to the horizontal direction and decorative materials.

[0030] Effects of the Invention

[0031] Among the existing methods for constructing floor heating systems, the wet construction method using cement mortar to permanently fix cross-linked polyethylene pipes is the most widely used method for constructing floor heating systems, but it has the following disadvantages:

[0032] First, because it cannot be heated quickly, energy is wasted.

[0033] Second, the cement solidification time is 7 days and the drying time is 30 days, so the construction time is too long. (If it is not dry, the floor as the final decorative material cannot be constructed.)

[0034] Third, the height is more than 50mm and the weight is heavy.

[0035] Fourth, the thick and heavy bottom decorative layer is difficult to install and dismantle, which is the core factor producing the weight sound which is the biggest cause of floor noise, and a large amount of waste is generated when it is dismantled.

[0036] If the floor heating system is constructed using the concave-convex metal plate according to the present invention, the concave-convex metal plate can be used as a floor structural material, thus having a long service life, and the concave-convex metal plate has a high thermal conductivity and can be quickly heated without requiring curing time, thereby having the effect of shortening the construction time. In addition, since the material is light, it is not only light in weight but also has a low stacking height, making maintenance and repairs simple. The concave-convex metal plate and floor heating system according to the present invention can not only improve the problems existing in the dry construction of the floor heating system, but also solve the problems existing in the wet construction.

[0052] Best Mode for Carrying Out the Invention

[0053] Figure 6 The concave-convex metal plate 30 of the floor heating system according to the present invention is shown. The concave-convex metal plate 30 of the floor heating system according to the present invention is repeatedly bent to form a concave portion 31 and a convex portion 32 to transfer the weight from the upper part of the decorative material to the floor slab. Since the concave-convex metal plate is repeatedly bent to form concave portions and convex portions, the resistance to the weight from the upper part is significantly improved, so that while transferring the weight from the upper part of the decorative material to the floor slab, it is sufficient to bear the weight and can be used as a floor structural material.

[0054] like Figure 7As shown, the concave portion 31 of the concave-convex metal plate 30 accommodates the linear heating element 40, and while the left and right sides of the bottom are in contact with the linear heating element 40, heat is transferred from the linear heating element. In the present invention, the heating element 40 is a general term for heating materials that are formed in a linear shape with a circular cross-section and a relatively long length, and provide heat to the floor heating system, including cross-linked polyethylene pipes, heating pipes, electric heating cables, etc. Since the concave portion of the concave-convex metal plate is in contact with the heating element at the bottom and on the left and right sides, heat can be effectively transferred from the heating element.

[0055] The lower part of the concave part or the upper part of the convex part of the concave-convex metal plate 30 may have a flat surface. In the floor heating system according to the present invention, the heat diffusion plate 20 is provided at the upper and lower parts of the concave-convex metal plate. If the lower part of the concave part or the upper part of the convex part has a flat surface, the concave-convex metal plate 30 and the heat diffusion plate 20 can be in surface contact, thereby achieving a more stable combination.

[0056] In addition, if Figure 7 and Fig.10 As shown, the concave portion of the concave-convex metal plate is formed in an arc shape 80 to contact the lower part of the left and right sides of the linear heating element. When the concave portion is formed in an arc shape, the contact surface with the heating element becomes larger, so that heat can be transferred from the heating element more effectively.

[0057] Furthermore, the concave-convex metal plate according to the present invention can also form only the concave portion for accommodating the linear heating element into a circular arc shape 80. That is, although the concave-convex metal plate is repeatedly formed with concave-convex, not all concave portions accommodate the heating element. The concave portions of the concave-convex metal plate that need to accommodate the heating element and those that do not can be planned in advance according to the overall heating area and the type and degree of curvature of the heating element, so that only the concave portions that need to accommodate the heating element can be formed into a circular arc shape 80.

[0058] Furthermore, unlike the case where the recessed portions and the raised portions are formed in one direction in the recessed and raised portions of the recessed and raised metal plate described so far, the recessed portions and the raised portions may be formed continuously in two directions. Figure 8 A concave-convex metal plate in which concave portions and convex portions are continuously formed in two directions according to another embodiment of the present invention is shown.

[0059] Since the heating element is received along the concave portion, if the concave portion and the convex portion are formed in one direction, the receiving direction of the heating element can only be limited to one direction. Figure 8 As shown, if the concave and convex parts of the concave-convex metal plate are formed in two directions, the heating element can be accommodated in both directions, thereby making it easier to adjust the installation direction of the heating element.

[0060] The concave-convex metal plate according to the present invention can be formed of a material selected from iron plate, color steel plate, synthetic resin coated plate, zinc electroplated plate, aluminum-zinc alloy steel plate, galvanized steel plate, tin electroplated steel plate, aluminum, duralumin, aluminum alloy plate, copper plate, brass, and bronze.

[0061] The concave and convex metal plate can be formed by one of gear forming, roll forming and stamping forming.

[0062] like Fig.12 As shown, the gear is formed by setting two gears 90 and passing the metal plate between the gears 90. This method has low mechanical production cost and high productivity, and can form the iron plate structure material according to the shape of the gear structure.

[0063] like Fig.13 As shown, roll forming is a method of continuously forming and cutting into appropriate size shapes by using multiple steps of pressure to transfer a continuous long iron plate of appropriate size while using multiple rollers 91 to bend or fold it into a desired shape.

[0064] like Fig.14 As shown, the press forming is a method of manufacturing a mold 92 having a concave-convex metal plate cross-sectional shape and manufacturing it by a press operation.

[0065] Next, the construction method of the floor heating system using the concave-convex metal plate according to the present invention is described. The materials used for the bottom surface according to the present invention are: 1. Heating element 40; heat diffusion plate 20 with a length of 600 mm in horizontal direction and 600 mm in vertical direction; 3. Silicon for bonding; 4. Bolts 50 for iron plate; 5. Concave-convex metal plate 30.

[0066] The following is an explanation of the construction process of the above materials. On the leveled floor slab, extrude the adhesive silicon bonding insulation material 10 with a thickness of wooden chopsticks at a spacing of about 200mm. The insulation material 10 prevents the heat from the heating element from being transferred to the floor slab direction. Any form of insulation material 10 is acceptable, but preferably, a hard compressed foam polystyrene (extruded polystyrene) type is used to prevent compression deformation. Adhesive silicon is squeezed again on the insulation material to bond the lower heat diffusion plate 20. After the lower heat diffusion plate 20 is completely pasted to the ground, the concave-convex metal plate 30 is bonded with an adhesive. The heating element 30 is installed on the concave-convex metal plate 20 according to the installation interval, and the heating element and the concave-convex metal plate are fixed to the iron plate ground with iron plate bolts 50. The portion where the heating element needs to be bent and circuitous is fixed to the space after the concave-convex metal plate is cut according to the space. After the heating element and the concave-convex metal plate are completely installed, the gap between the heating element and the concave-convex metal plate is filled with curing mortar such as silicon, tile adhesive or cement. After the gap filling process is completed, the bonding silicone is extruded at intervals of about 100 mm, and the upper heat diffusion plate 20 with a horizontal length of 600 mm and a vertical length of 600 mm is bonded to the entire construction surface at intervals of 1 to 2 mm. The upper heat diffusion plate is bonded and the decorative material is constructed on the upper part of the upper heat diffusion plate to complete the construction of the dry floor heating system according to the present invention.

[0067] The floor heating system of the present invention completed by the construction method includes: an insulating material 10, which prevents heat from the heating element from being transferred to the floor slab direction; a lower heat diffusion plate 20, which is located on the upper part of the insulating material and transfers the heat conducted from the heating element to the horizontal direction; a concave-convex metal plate 30, which is located on the upper part of the lower heat diffusion plate and accommodates the heating element; the heating element 40 is accommodated in the concave part of the concave-convex metal plate; an upper heat diffusion plate 20, which is located on the upper part of the concave-convex metal plate and transfers the heat conducted from the legal person to the horizontal direction and decorative materials.

[0068] In the present invention, the upper heat diffusion plate and the lower heat diffusion plate can be selected from metal material plates such as aluminum-zinc alloy steel plate, galvanized steel plate, color steel plate, tin-plated steel plate, zinc-plated steel plate, aluminum plate, stainless steel plate, copper plate, or synthetic resin plate, wooden plate, inorganic plate. In addition, the material of the upper heat diffusion plate and the material of the lower heat diffusion plate can be selected from different materials, for example, the upper heat diffusion plate can be selected from a metal material plate, and the lower heat diffusion plate can be selected from a synthetic resin plate, wooden plate, inorganic plate.

[0069] Because the concave-convex metal plate is made into a three-dimensional structure with concave and convex parts on the metal plate to better withstand pressure, when installed as a kang board, it can withstand the weight of more than one ton per square meter of refrigerators.

[0070] In addition, cement mortar has relatively low properties, with a heat storage capacity of about one-third and a thermal conductivity of about five to six times that of metal of the same mass. Therefore, when a plate-like structure made of a metal material with better properties than cement is used in a heating system, heat from the heating element 40 can be obtained from four directions, and the thermal conductivity is more than five times faster than that of cement mortar. The heat from the heating element is conducted to the room faster than cement mortar, increasing the efficiency of heat energy inflow by at least two to three times.

[0071] In addition, when cement is used for floor heating construction, the service life reaches more than 30 years. The zinc-plated plate, one of the materials of the concave and convex metal plate, electroplates zinc that ionizes faster than iron on the iron plate to prevent oxygen corrosion, and the corrosion life reaches more than 30 years semi-permanently, which is no different from construction with cement mortar.

[0072] The new gold-plated iron plate used as the material of the heat diffusion plate and the concave-convex metal plate is the most common type of iron plate around us. It is an easily available material, and it is easy to disassemble and can be recycled, so there is less worry about the generation of waste.

[0073] According to the floor heating system of the present invention, final decorative materials such as plywood floors can be used only one day after construction, thereby shortening the construction time. Compared with the existing cement wet construction, it is not only thinner in thickness and lighter in weight, but also all construction can be completed in one day. The metal plates can be recycled during disassembly, thereby solving the problems existing in the existing cement wet construction, such as reducing the generation of waste.

[0074] Industrial Applicability

[0075] The present invention is applicable to the field of floor heating industry, and the floor heating system is constructed by using the concave-convex metal plate, which is simple and can improve the construction efficiency and heating efficiency.
