Wall panels for fire-resistant partition structures with fire-resistance}

The present invention relates to a wall panel for a partition structure. More specifically, the present invention relates to a wall panel for a partition structure. More specifically, the present invention relates to a wall panel for a partition structure. More specifically, the present invention relates to a wall panel for a partition structure. More specifically, the present invention relates to a wall panel for a partition structure. More specifically, the present invention relates to a separately provided fire-resistant gypsum board between the front steel finishing material and the rear steel finishing material through the top finishing member, the inner support member, and the gap maintenance member, and polyurethane is used. By producing and providing wall panels made of foam molding, we are talking about wall panels for fire-resistant partition structures that are very lightweight compared to existing fire-proof wall panels and are capable of producing excellent fire prevention and fire resistance.

In general, lightweight partition panels made by forming a polyurethane foam layer between the front steel finishing material and the back steel finishing material are widely used for ceiling finishing of refrigerated and frozen warehouse facilities, indoor waiting rooms, underground passages, or indoor and outdoor partition walls. there is.

Such polyurethane panels are lightweight, have excellent manufacturing efficiency, and at the same time have certain heat and sound insulation effects, so they are widely used in various fields. In addition, since the general polyurethane panel as described above does not have excellent fire resistance, in order to reinforce and supplement this, a fire-resistant panel is made by embedding or attaching a separate gypsum board to the inside or outside of the polyurethane panel. In the case of such fire-resistant panels, the excellent fire prevention and fire resistance of gypsum board prevents fire or high temperature heat generated inside or outside the partition space from being conducted, radiated, or spread through the partition wall or ceiling. I do it.

In particular, as in the recent Registration Patent No. 10-0555129, a flame-retardant polyester board made of polyester fibers impregnated and dried with a water-soluble inorganic flame retardant, a reinforcing steel plate attached to both outer sides of the polyester board, and this steel plate. In another embodiment, it includes a border material attached to the edge of the reinforcing steel plate, a polyester laminate made of polyester fibers impregnated and dried with a water-soluble inorganic flame retardant on the outside of the reinforcing steel plate, and attached to the surface of the polyester laminate. A partition panel that further includes a surface finishing layer has been developed and registered. This allows the partition to be finished without using additional finishing materials such as painting or wallpaper when installing a partition inside a building, and is more effective than existing partitions. It has excellent impact resistance, has high sound insulation effect as well as sound absorption, and is designed to increase safety by preventing smoke and harmful gases from being generated even in the event of a fire.

However, the above-described partition panel has a problem of extremely poor productivity and economic efficiency because the manufacturing process is very complicated and is produced through many steps. It takes a considerable amount of time to attach or embed a reinforcing steel plate into a flame-retardant polyester board made of fiber. It requires technical skills, a lot of work processes, and production time, and the polyester board, reinforcing steel plate, and metal border materials are heavy, so they have the problem of being difficult to handle during production, transportation, and construction.

Next, as in the case of Patent No. 10-0917864 as another existing prior example, a vermiculite board, an inorganic primer layer applied to both sides of the vermiculite board, an adhesive layer applied on the inorganic primer layer on both sides, and an adhesive layer on both sides. A fireproof board including a reinforcing board bonded on top, wherein the inorganic primer layer is formed of an inorganic primer composition containing 45 to 55% by weight of an ethyl silicate solution and 45 to 55% by weight of an acrylic emulsion resin solution based on the total weight of the composition. In the above, the ethyl silicate solution is 38% by weight of ethyl silicate solids dissolved in 62% by weight of alcohol based on the total weight of the ethyl silicate solution, and the acrylic emulsion resin solution in the above is acrylic emulsion resin based on the total weight of the acrylic emulsion resin solution. A fireproof board and a partition panel using the same, characterized by dissolving 45 to 55% by weight of solid content in 45 to 55% by weight of alcohol or water, have been developed and registered. These fireproof boards and partition panels emit far infrared rays that are beneficial to the human body. It is stated that it maintains the advantages of vermiculite board, which has excellent deodorizing and antibacterial properties and excellent fire resistance, and the strength, durability, and water resistance of the board are strengthened, producing excellent characteristics.

However, the preceding example is not only unsuitable for mass production because it is not excellent in productivity, handling, and quality stability, but also has the problem of being extremely uneconomical. In addition, it has structural vulnerability and is easily damaged, so repeated use is hardly possible. This is actually causing a large increase in the amount of construction waste generated.

Next, in the case of Publication Patent No. 10-2021-0016468, which was designed to solve the existing problem, a surface material and a back material made of a metal material, a plurality of organic insulation board layers disposed between the surface material and the back material, and the plurality of organic insulation boards A partition panel in which an inorganic board layer is sandwiched between the layers, and the surface material of a plurality of organic insulating board layers adjacent to the surface material and the back material of a plurality of organic insulating board layers adjacent to the back material are bonded to each other with an organic adhesive. As this has been developed, it can be seen as a characteristic that it has both high fire resistance and insulation properties.

However, in the case of the above preceding example, productivity is still not excellent because it is made in the form of a composite lamination of many components such as a surface material, a back material, and a plurality of organic insulating board layers and an inorganic board layer, as well as many production processes and components. Compared to existing partition panels, it is very heavy and has extremely poor handling properties such as transportation and construction, and the multiple organic insulation board layers located inside the metal surface material and back material and the inorganic board layer between them are used during the molding and manufacturing process of the product. It is true that it has extremely disadvantageous disadvantages in terms of quality stability, such as flow, and is therefore very economical.

A detailed perspective view of the built-in gypsum board and support means for the wall panel of FIG. 5 is an enlarged cross-sectional view of the entire flat cross-section and both ends of the wall panel of the present invention.

As shown, the wall panel for a partition structure according to the present invention has a gypsum board (30) embedded between the front steel finishing material (10) and the rear steel finishing material (20), in which the polyurethane foam molding layer (1) is formed. The upper and lower ends of the front steel finishing material (10) and the rear steel finishing material (20) are respectively embedded in the upper and lower bending ends of the front steel finishing material (10) and the rear steel finishing material (20). Corresponding fitting protrusions (2) and fitting grooves (3) are formed by the bent ends on both sides of the steel finishing material (20).

Here, the front steel finishing material 10 and the rear steel finishing material 20 are made by bending a rectangular metal plate in all directions, and the front steel finishing material 10 and the rear steel finishing material 20 are in a bent end state. By joining opposite to each other, it has a predetermined internal space, and by injecting and foaming polyurethane into this internal space, a wall panel with a certain size and thickness can be completed.

In addition, inside the upper and lower bent ends of the front steel finishing material 10 and the rear steel finishing material 20, the upper and lower ends of the wall panel are finished, respectively, and the upper and lower ends of the extrusion molding 40 are provided for structural reinforcement. The finishing port 50 is built-in, and the molten polyurethane resin can be injected into the internal space through the plurality of injection holes 51 and 51' formed in the lower closing port 50. The injection hole 51 (51') is automatically opened when the injection of the polyurethane resin is completed by a separately provided opening and closing plate (not shown in the drawing) located on the inner side of the bottom finishing hole 50. 51) (51') is sealed to prevent the polyurethane being foamed from being exposed to the outside.

In particular, the bent portions at both ends of the front steel finishing material 10 and the rear steel finishing material 20 are configured to form fitting protrusions 2 and fitting grooves 3 of opposing sizes, respectively, in the process of constructing the partition structure. When the wall panels are installed continuously, the fitting protrusions (2) and fitting grooves (3) between adjacent wall panels are locked together, allowing quick and easy construction of a continuous wall.

Here, inside the bent portions of both ends of the front steel finishing material 10 and the rear steel finishing material 20 as described above, a separately provided closed bending table 80 (80') is formed by bending a metal plate in a 'ㄷ' shape. By additionally inserting and forming, it will be possible to prevent the polyurethane resin from leaking through the gap between the front steel finishing material 10 and the rear steel finishing material 20 during the foam molding process of the polyurethane resin.

Next, in the present invention, a separately provided gypsum board (30) is embedded in the space between the front steel finishing material (10) and the rear steel finishing material (20), and the tip of the gypsum board (30) is located at the upper finishing hole. It is coupled to the inner part of (40), and the lower end of the gypsum board (30) is coupled to a separately provided internal support member (60) (60') located at a distance from the upper part of the bottom finishing member (50), and the front steel finishing material (10) ) and the inner surface of the rear steel finishing material (20), the gypsum board (30) is positioned spaced apart.

Therefore, when the polyurethane resin in a molten state is injected into the internal space through the injection holes 51 and 51' of the bottom closing port 50, the entire surface is formed by the polyurethane foam molding layer 1, which has adhesive properties and is foam molded. The steel finishing material 10, the back steel finishing material 20, and the gypsum board 30, as well as the internal support members 60 and 60', can be fixed in a solid mutual bonding state.

Here, the gypsum board 30 is not inserted into the entire internal space between the front steel finishing material 10 and the rear steel finishing material 20, but is inserted into the inner support section 60 (60') from the upper finishing hole 40. By being built to have a length of only up to The polyurethane resin injected into the internal space through the finishing hole (50) avoids direct interference with the embedded gypsum board (30), and at the same time, a sufficient amount of polyurethane resin is quickly injected into the filling and foaming space (4). In addition to providing enough free space during the foam molding process of the polyurethane resin due to the filled foam space (4), the foam molded layer (1) can be created in an even overall state without voids.

In particular, in the case of a wall panel having a fire resistance function of the present invention, considering that heat in the event of a fire has a greater effect on the upper part of the wall panel than on the lower part, gypsum board 30, which has excellent fire prevention performance and fire resistance, is placed on the upper part of the wall panel. The filling foam space (4) is configured to have a minimum size that allows the polyurethane foam molding layer (1) to be formed quickly and stably, thereby contributing to lightening the wall panel while maintaining excellent fire protection performance. It can be.

In addition, the above-described gypsum board 30 is configured by forming a repeating array of joint through-holes 31 and 31', so that when molten polyurethane resin is injected, the molten resin is formed into the joint through-holes 31. Through (31'), the space between the front steel finishing material (10) and the gypsum board (30) and the space between the rear steel finishing material (20) and the gypsum board (30) are quickly filled to prevent a decrease in the injection speed of polyurethane. Polyurethane is evenly injected throughout the interior space so that it can be foam molded. At the same time, the joint through-holes 31 and 31' allow the embedded gypsum board 30 to be used with the front steel finishing material 10 and the rear steel finishing material. (20) will be stably fixed at a certain distance between them, while further improving the bonding efficiency between them.

Next, as shown in FIG. 6, the above-mentioned top finishing tool 40 forms an insertion groove 41 along the longitudinal direction toward the inside of the panel, thereby inserting the upper end of the gypsum board 30 through the insertion groove 41. This is inserted, and an end guide 42 for guiding the combination of the gypsum board 30 is further protruded on one side of the above-mentioned insertion groove 41, and the end of the gypsum board 30 is formed in the insertion groove 41. ), the end of the gypsum board (30) can be pressed into close contact with the end guide (42) and inserted into the insertion groove (41), making mutual assembly simpler and faster. will be.

In addition, as shown in FIG. 7, the inner support parts 60 and 60' coupled to the bottom of the gypsum board 30 are in close contact with the inner surfaces of the front steel finishing material 10 and the rear steel finishing material 20 on both sides. Flat surface interview portions 61 and 61' are provided, and board fitting grooves 62 and 62' having different spacing widths are provided between the interview portions 61 and 61' in the upper and lower directions. It is constructed by dividing the gypsum board 30 into various thicknesses according to the size and thickness of the wall panel using board fitting grooves 62 and 62' having different spacing widths.

That is, if the inner width of the board fitting grooves 62 (62') on one side is 13 mm, gypsum board 30 with a thickness of 12.5 mm can be embedded, and the board fitting grooves 62 (62') on the other side. ) If the inner width is 10 mm, the bottom of the gypsum board 30 with a thickness of 9.5 mm can be joined. By changing the thickness of the gypsum board 30, it is possible to achieve the purpose of constructing the partition structure. Accordingly, it will be possible to control the fire prevention and fire resistance performance of the wall panel.

Next, on both sides of the gypsum board 30 as described above, gap maintainers 70 and 70' are formed by inserting and forming a gap between the inner surface of the front steel finishing material 10 and the inner surface of the rear steel finishing material 20, respectively. It is configured to prevent the front steel finishing material 10 and the rear steel finishing material 20 from sinking into the gypsum board 30 during the compression molding process for the urethane foam molding layer 1, and the gap maintenance member 70 ( 70') is in close contact with the outer surface of the gypsum board 30, and a plurality of support ribs 71 (71') are formed to protrude in the outward direction so that polyurethane is evenly filled between the support ribs (71) (71'). It is composed.

Therefore, in order to form the polyurethane foam molding layer (1), when a plurality of wall panel assemblies with internal spaces are stacked and polyurethane resin is injected into the interior of each wall panel, the internal filling foam space (4) ), the polyurethane resin can be quickly filled, and the upward and downward expansion forces during the foam molding process are suppressed due to the stacking pressure applied to multiple panels, and the collapse of the panels due to excessive stacking pressure occurs at the top. As it is supported and suppressed by the finishing member 40, the bottom finishing member 50, the internal support member 60, 60', and the gap maintenance member 70, 70', the wall panel of the present invention is even throughout. It will be possible to make it with stable thickness and quality.

In addition, due to the built-in gypsum board 30, the thickness of the polyurethane foam molding layer 1 inside the wall panel will be formed only to a minimum thickness on both sides of the gypsum board 30, and this minimum polyurethane foam will be formed. The thickness of the forming layer functions to suppress the spread of combustion by flame or heat, allowing the wall panel of the present invention to produce excellent fire protection performance.
