Description

[Technical Field]

[0001] The present invention relates to a panel material, and more particularly to a panel material that can be easily installed and that can suitably exhibit performance as a bearing wall while maintaining heat insulating performance. [Background technology]

[0002] In wooden buildings such as houses, insulation is filled inside the framework of a frame structure consisting of columns and beams to improve thermal insulation. Furthermore, to improve earthquake resistance, shear panels are attached to seal the framework from the outside, creating internally insulated walls. Traditionally, construction work for wooden buildings involves cutting relatively large insulation materials (e.g., 910mm x 3030mm, 910mm x 1820mm, etc.) and shear panels (e.g., 910mm x 3030mm) to the appropriate size and shape at the construction site to match the dimensions and shape of the installation location. This construction work generates chips (waste) and dust during the processing of the insulation and shear panels, requiring on-site cleaning each time. There is also the risk of the dust scattering and other environmental pollution in the neighborhood. Furthermore, depending on the skill of the craftsman, it may be difficult to cut the insulation and shear panels to the appropriate size and shape, potentially resulting in insufficient insulation and earthquake resistance performance. Therefore, in recent years, in wooden buildings, it has been proposed to use insulating wall panel materials that integrate load-bearing surface materials and insulating materials and are pre-formed (hereinafter also referred to as "pre-cut") in a factory or the like to a size and shape that corresponds to a certain extent to the dimensions and shape of the installation location of the house or the like, thereby simplifying the construction work (see, for example, Patent Documents 1 and 2).

[0004] Even if the panels, which integrate the load-bearing surface material and the insulation material, are pre-cut, they still require work to adjust the size and cut or shave the insulation material at the construction site.In particular, to fully demonstrate earthquake resistance, it is necessary to leave gaps between adjacent load-bearing surface materials, but the work of cutting or shave the insulation material at the construction site to accurately create such gaps and to produce the panel material to the correct size is complicated and extremely difficult.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a panel material that can be easily installed and can optimally perform as a load-bearing wall while maintaining its insulating performance. [Means for solving the problem]

[0006] As a means for solving the above problems, the invention of a panel material described in claim 1 is a panel material that is attached to a framework structure consisting of columns and beams that constitutes a wooden building to form an internal insulated wall, and is characterized by comprising a load-bearing face panel and an insulating material provided on one side of the load-bearing face panel, the insulating material determining the installation position of the load-bearing face panel relative to the framework structure of the house, and a position adjustment section on the widthwise side of the insulating material for adjusting the installation position of the insulating material relative to the framework structure of the house. Here, the framework structure is a structure formed into a frame shape by combining columns and beams that constitute, for example, a house, etc. The invention of the panel material described in claim 2 is characterized in that, in the invention of the panel material described in claim 1, the side edge of the bearing surface material has a notch portion into which the beam is inserted. The invention of the panel material described in claim 3 is based on the invention of the panel material described in claim 1, and is characterized in that the peripheral portion of one side of the load-bearing surface material has a filler portion that fills the gap between the column and / or beam and the load-bearing surface material. The panel material invention described in claim 4 is characterized in that, in the panel material invention described in claim 1, the lower end of the insulating material has a spacer portion that engages with the end of the floorboard of the wooden building. [Effects of the Invention]

[0007] The panel material of the present invention is for forming an internal insulating wall of a wooden building, and comprises a bearing face material and an insulating material provided on one side of the bearing face material. This panel material can be constructed by simply installing the panel material on a framework structure consisting of columns and beams that constitutes a wooden building, thereby forming both a bearing wall made of the bearing face material and an insulating layer made of the insulating material. This allows for easy installation, and the panel material can optimally perform as a bearing wall while maintaining its insulating performance. In other words, since the insulation material determines the installation position of the load-bearing surface material relative to the frame structure of a wooden building, by installing the insulation material in the frame structure, the position of the load-bearing surface material relative to the frame structure can be reliably determined. Furthermore, the side of the insulation material is provided with a position adjustment section that adjusts the installation position of the insulation material relative to the frame structure of a wooden building, so that the installation position of the side of the insulation material relative to the frame structure can be suitably adjusted. In other words, since the panel material of the present invention is prepared with high precision in advance, there is no need for complicated processing work at the construction site, such as adjusting dimensions and cutting load-bearing surface materials and / or insulation materials. Furthermore, when the load-bearing surface material has a notch for inserting a beam, there is no need for complicated processing work such as forming a portion for inserting a beam in the panel material at the construction site. Furthermore, if a filler portion is provided on the peripheral edge of one side of the load-bearing surface material to fill the gap between the columns and / or beams and the load-bearing surface material, airtightness and / or vibration-damping properties can be imparted between the frame structure and the load-bearing surface material. Furthermore, if the lower end of the insulation material has a spacer portion that engages with the end of the floorboard, there is no need for the complicated work of processing a separately prepared spacer to fit the installation location at the construction site, resulting in excellent work efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying the present invention will be described below. [Embodiment 1] The panel material 10 of embodiment 1 is a panel material for constructing an internal insulating wall of a wooden building, and as shown in Figures 1(a) and (b), it comprises a load-bearing surface material 11 and an insulating material 12 provided on one side of the load-bearing surface material 11. Here, a wooden building refers to a structure that is made up of wooden columns and beams assembled into a framework to support the weight of the building, etc. Such wooden buildings usually include houses, but can also include wooden buildings other than houses. Furthermore, a pillar refers to a vertical member that extends vertically in a wooden building, and this pillar includes through pillars, partition pillars, etc. In addition, a beam refers to a horizontal member provided to extend in the lateral direction (horizontal direction) in a wooden building, and this beam shall include floor beams, connecting beams, body braces, etc.

[0010] Specifically, the panel material 10 is formed by integrating the load-bearing surface material 11 and the heat insulating material 12 by joining the heat insulating material 12 to the load-bearing surface material 11. The heat insulating material 12 is for imparting heat insulation performance to the panel material 10 by preventing heat transfer from the inside to the outside of the heat insulating material 12 with the side where the heat insulating material 12 of one side of the load-bearing surface material 11 is joined being defined as the inner side. The load-bearing surface material 11 is formed in a rectangular plate shape using a material that can be fixed by nailing, such as plywood, medium-density fiberboard, hardboard, volcanic glass plate, particle board, wood-cement board, thermoply, etc. The heat insulating material 12 is formed in a rectangular plate shape using a porous material to prevent heat transfer from the inside to the outside of the wooden building and to allow moisture to escape from the inside to the outside of the house. Examples of the porous material include plastic foams such as polystyrene foam, phenolic resin foam, polyethylene foam, polypropylene foam, semi-rigid polyurethane foam, and melamine resin foam.

[0011] The heat insulating material 12 determines the installation position of the load-bearing surface material 11 with respect to the frame structure of the wooden building. That is, the panel material 10 has a function of being able to determine the installation position of the load-bearing surface material 11 by installing (inserting) the heat insulating material 12 into the frame structure. Furthermore, a position adjusting part 13 is provided in a stepped shape on the side part of the heat insulating material 12. That is, as shown in Fig. (b) of the same figure, in the width (lateral width) direction of the panel material 10, the length W1 of the heat insulating material 12 is set shorter than the length of the load-bearing surface material 11 (W1 < W2). Therefore, on the side surface of the panel material 10, a stepped position adjusting part 13 with the width adjusted according to the difference between the length W2 of the load-bearing surface material 11 and the length W1 of the heat insulating material 11 is formed. The action and effect thereof will be described later.

[0012] As shown in Figure 2(a), in a wooden building such as a house, a base 28 is fixed onto a foundation (not shown), multiple pillars 21 are erected on the base 28 at predetermined intervals, and beams 25 are supported and fixed on the pillars 21 to form a frame structure. The panel material 10 has load-bearing face materials 11 nailed to the pillars 21 and beams 25 of the frame structure, and the frame (framework) made up of the pillars 21 and beams 25 is fixed to form a load-bearing wall that can withstand lateral forces caused by earthquakes, wind, etc. The insulation material 12 forms an insulating layer on the inside of the load-bearing wall, thereby forming an internally insulated wall of a wooden building using the internal insulation method. However, not all panel materials 10 used in a single wooden building are necessarily configured the same. For example, some panel materials 10 may be formed with a shorter width or length than other panel materials 10, or may have holes for attaching window frames, so the shape and size must be changed appropriately to suit the actual situation.

[0013] In a framework structure, studs 22 may be provided between a plurality of columns 21. The heat insulating material 12 may be provided at the middle in the width direction with a positioning portion 12a into which the studs 22 are fitted. If the studs 22 are already installed when the panel material 10 is installed, as shown in Figure 2(b), the positioning portions 12a (see Figure 1(b)) provided in the middle of the width of the insulation material 12 can be fitted into the studs 22 to assist in the installation of the insulation material 12 on the frame structure and ensure the position of the load-bearing face panel 11 relative to the columns 21 of the frame structure. Alternatively, if the studs 22 are installed after the panel material 10 is installed, the installation position of the studs 22 can be determined by fitting the studs 22 into the positioning portions 12a. Furthermore, a stepped position adjustment portion 13 (see Figure 1(b)) is provided on the side of the insulation material 12, making it possible to suitably adjust the installation position of the side of the insulation material 12 relative to the pillar 21 of the frame structure. That is, by installing the panel material 10 in an appropriate position, the side surface 12p of the insulation material 12 can be butted against the side surface 21p of the pillar 21 so that no gaps that would affect the insulation performance are formed, that is, there are virtually no gaps, resulting in excellent insulation effects. Similarly, the side surface 12p of the insulation material 12 can be butted against the side surface 22p of the stud 22 so that there are virtually no gaps, resulting in excellent insulation effects. Meanwhile, in the load-bearing face materials 11 of the panel material 10, position adjustment portions 13, which are steps between adjacent panel materials 10 in the left-right direction, come together to form gaps S1 between the load-bearing face materials 11. The gaps S1 are intended to maintain the performance of the load-bearing wall made of the load-bearing face materials 11. In other words, by providing the gap S1, the shear wall made up of the left and right shear face panels 11 functions to release the load caused by contact between the shear face panels 11 when force is applied from the lateral direction, and can maintain its performance as a shear wall made up of the shear face panels 11.

[0014] With the panel material 10 of embodiment 1, simply by fitting the insulating material 12 between a pair of pillars 21, the position of the load-bearing surface material 11 relative to the pillars 21 can be reliably and accurately determined, and at the same time, a gap S1 is formed to allow the load caused by contact between the load-bearing surface materials 11 to escape, making it easy to install and allowing the material to optimally perform as a load-bearing wall while maintaining its insulating performance. Therefore, in the past, even if panel materials integrating load-bearing surface materials and insulating material were pre-cut and prepared, it was essentially necessary to adjust the size at the construction site and cut or shave the insulating material, whereas panel material 10 is prepared with high precision in advance, so there is no need for complicated processing work at the construction site, such as adjusting the dimensions at the construction site and shave off load-bearing surface material 11 and / or insulating material 12.

[0015] In other words, the panel material 10 can be attached to the frame structure simply by fitting the insulating material 12 between a pair of pillars 21, with the installation positions of the load-bearing panel 11 and the insulating material 12 relative to the frame structure already determined, so there is essentially no need for complicated processing work at the construction site. Such panel material 10 is manufactured by pre-cutting in a factory or the like other than a construction site, in which the positioning portion 12a and the position adjustment portion 13 are formed in advance on the heat insulating material 12 using a CAD / CAM system. The manufacturing of the panel material 10 using a CAD / CAM system involves processing based on CAD data of the blueprints of the wooden building, which allows for high processing precision in the manufacturing of the panel material 10. Therefore, simply by fitting the positioning portion 12a as described above into the stud 22 (or pillar 21), it is possible to accurately determine the installation positions of the load-bearing surface panel 11 and the heat insulating material 12 relative to the framework structure.

[0016] [Embodiment 2] As shown in Fig. 3, the panel material 30 according to the second embodiment comprises a load-bearing face material 31 and a heat insulating material 32 provided on one surface of the load-bearing face material 31. The panel material 30 is formed with a cutout portion 31h formed by cutting out a side edge portion of the load-bearing face material 11 according to the first embodiment in a substantially rectangular shape, and forms part of a hole portion 31H described below. 4(a) and (b), for example, in a veranda, a beam (handrail) 26 is supported and fixed to a pillar 21 inside a wooden building by a tenon 26t, and the beam 26 is inserted into a hole 31H surrounded by a panel material 30 and plate materials 35 and 37. A window frame 28 adjacent to the pillar 21 is provided to the left of the plate materials 35 and 37. At the location where the beam 26 is inserted, a gap S2 is provided around the hole 31H between the panel material 30, the plate materials 35, 37 and the beam 26 so as to release the load caused by contact with each other. A gap S1 is also provided between the plate material 35 and the panel material 30, where the beam 26 is not inserted, to release the load caused by contact between them.

[0017] As with the panel material 10 of embodiment 1, the panel material 30 of embodiment 2 can reliably and accurately determine the position of the load-bearing surface material 31 relative to the columns 21 simply by fitting the insulating material 32 between a pair of columns 21, and at the same time, a gap S1 is formed to allow the load caused by contact between the load-bearing surface material 31 and the plate materials 35, 37 to escape, making it easy to install and allowing the panel material to optimally perform as a load-bearing wall while maintaining its insulating performance. Therefore, in the past, even if panel materials that integrated load-bearing surface materials and insulating material were pre-cut and prepared, it was essentially necessary to adjust the size at the construction site and cut or shave the insulating material, whereas panel material 30 is pre-cut based on CAD data of the wooden building blueprint, and is precisely prepared in advance, including the cutout portion 31h into which beam 25 is inserted, so there is no need for complicated processing work at the construction site, such as adjusting the dimensions at the construction site and shave the load-bearing surface material 31 and / or insulating material 32.

[0018] [Embodiment 3] As shown in Figures 5(a) and (b), the panel material 40 of embodiment 3 is the panel material 10 of embodiment 1, with a filler portion 60 provided on the peripheral edge of one side of the load-bearing surface material 11. The filler portion 60 is formed by being attached to the peripheral edge of one side of the bearing surface material 11. The filler portion 60 is intended to fill gaps formed between the columns 21 and / or beams 25 and the bearing surface material 11. By providing the filler portion 60, the panel material 40 can impart airtightness and / or vibration damping properties between the beams 25 and the bearing surface material 11. Although there are no particular limitations on the filler portion 60, a tape material is usually suitably used. In particular, a so-called cushion tape having a thick base material is preferable. Also, the adhesive surface may be provided on both sides instead of just one side, and the load-bearing surface material 11 and the beam 25 may be adhesively fixed. Conventionally, it was necessary to attach airtightness adjusting members and the like to panel materials at the construction site, but with panel material 40, the filler sections 60 are pre-installed with high precision. Therefore, there is no need for the complicated processing work of adjusting dimensions and attaching airtightness adjusting members and the like at the construction site. The above has been described using an example in which the panel material 40 is attached to the beam 25, but the same configuration is also applicable to the case in which the panel material 40 is attached to the pillar 21, and similar effects can be achieved.

[0019] [Embodiment 4] As shown in Figure 6(a), the panel material 50 according to the fourth embodiment comprises a load-bearing surface material 11 and a heat insulating material 42 provided on one surface of the load-bearing surface material 11. A spacer portion 42s that engages with the end of the floorboard 70 is formed at the lower end of the heat insulating material 42 so as to protrude in a stepped shape. Conventionally, as shown in Fig. 1(b), in order to insert and fix floorboards 70 onto beams 25 to which panel materials 10 are fixed, spacers 80 are inserted into the spaces created at the bottom ends of the heat insulating materials 12, and floorboards 70 are installed without gaps. This requires work at the construction site to adjust the size by cutting or grinding the spacers 80, which makes construction time-consuming. Therefore, as shown in Fig. 1(a), in the case of panel material 50, spacer portions 42s that can engage with the ends of floorboards 70 are accurately formed at the bottom ends of the insulation material 42, and therefore installation can be performed by simply engaging the ends of floorboards 70. This means that installation can be performed without the need to adjust the size by cutting or scraping the insulation material 42 at the construction site, resulting in excellent work efficiency.

[0020] The present invention is not limited to the above-described embodiments, and various modifications and variations are possible within the scope of the claims of the present invention. [Industrial Applicability]

[0021] The panel material of the present invention can be easily installed, and can exhibit favorable performance as a load-bearing wall while maintaining heat insulating performance, and therefore is industrially applicable. [Explanation of symbols]
