Description

[Technical Field]

[0001] The present invention relates to a method for manufacturing a heat insulating wall panel material, a heat insulating wall panel material, a method for constructing a house, and a house. [Background technology]

[0002] In wooden buildings such as houses, insulation is used to improve heat retention. Traditionally, construction work for wooden buildings involves cutting relatively large insulation materials (e.g., 910mm x 3030mm, 910mm x 1820mm, etc.) and load-bearing surface materials (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 when processing the insulation materials and load-bearing surface materials, requiring on-site cleaning each time. There is also the possibility of environmental pollution due to the scattering of dust. Furthermore, depending on the skill of the craftsman, it may not be possible to cut the insulation materials and load-bearing surface materials to the appropriate size and shape, resulting in insufficient insulation and seismic 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 matches 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, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-307439 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-010399 Summary of the Invention [Problem to be solved by the invention]

[0004] Typically, pre-cut insulating wall panels are used in either an internal insulating structure, in which the insulating material is installed inside the bearing surface (i.e., inside the wall), or an external insulating structure, in which the insulating material is installed outside the bearing surface (i.e., outside the columns and beams). For example, the insulating wall panel material described in Patent Document 2 is used in an external insulating structure. In recent years, the construction industry has been calling for further increases in insulation standards (higher insulation) from the perspective of environmental conservation, etc. However, there are cases where the insulation thickness of either an internally or externally insulated structure does not meet the required level of insulation. In such cases, a double-insulated structure is required, in which insulation is installed on both the inside and outside of the load-bearing surface material. Patent Document 1 describes the use of a CAD / CAM system to manufacture insulating wall panels in which insulating materials are attached to both the inside and outside of a load-bearing surface material, but does not describe the specific processing methods for each insulating material.Furthermore, it does not describe the specific correlation between the load-bearing surface materials of each panel material when the panels are installed adjacent to each other. In essence, the pre-cut manufacturing of double-sided insulated wall panels requires two processes: one for processing only the inner insulation material and one for processing only the outer insulation material, avoiding the load-bearing face panels that serve as structural members of wooden buildings. In other words, the manufacturing of double-sided insulated wall panels requires two or more work passes. For this reason, double-sided insulated wall panels have not been able to be manufactured efficiently.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a method for manufacturing an insulating wall panel material that can efficiently obtain an insulating wall panel material in which insulating material is attached to both sides of a load-bearing face material, the insulating wall panel material obtained by the manufacturing method, a method for constructing a house using the insulating wall panel material, and a house equipped with the insulating wall panel material.

[0009] The matters set forth herein are for illustrative purposes only and are intended to provide an illustrative description of the embodiments of the present invention, with the aim of providing what is believed to be the most effective and easily understandable explanation of the principles and conceptual features of the present invention. In this regard, it is not intended to show structural details of the present invention beyond the extent necessary for a fundamental understanding of the present invention, and the description, taken together with the drawings, will make clear to those skilled in the art how some forms of the present invention may be actually embodied.

[0010] Hereinafter, the present invention will be specifically described by way of embodiments with reference to the drawings.

[0011] <Method of manufacturing insulating wall panel material> The manufacturing method for an insulating wall panel material according to an embodiment of the present invention is a manufacturing method for an insulating wall panel material 1 (hereinafter also simply referred to as "panel material 1") that is attached between a pair of pillars 21, 21 to form a wall (see Figures 2 and 4).

[0012] As shown in Figure 1, the manufacturing method for panel material 1 includes a first step of attaching a first insulating material 3A to one side of load-bearing surface material 2 and a second insulating material 4A to the other side, and a second step of using a CAD / CAM system to cut the first insulating material 3A to form the outer insulating material 3 and to cut the second insulating material 4A to form the inner insulating material 4. That is, the manufacturing method of the panel material for the heat insulation wall can also be said to be a method of obtaining the panel material 1 used for a heat insulation structure (double-sided heat insulation structure) in which the outer heat insulation material 3 is installed on one side (outer side) of the load-bearing surface material 2 and the inner heat insulation material 4 is installed on the other side (inner side) by pre-cutting using a CAD / CAM system.

[0013] As the load-bearing surface material 2, for example, plate materials with high mechanical strength such as plywood, medium-density fiberboard, hard board, volcanic glassy plate, particle board, wood-cement board, and thermoply can be used. Furthermore, as each of the heat insulation materials 3A and 4A, for example, highly heat-insulating materials such as plastic foams such as polystyrene foam, polyethylene foam, polypropylene foam, and polyurethane foam or fiber sheets can be used. Each of the heat insulation materials 3A and 4A may be made of different materials or the same materials.

[0014] In the first step, for the first heat insulation material 3A, one having a width W1 wider than the width W of the load-bearing surface material 2 (W < W1) is used (see Fig. 1(a)). Also, for the second heat insulation material 4A, one having a width W2 equal to the width W of the load-bearing surface material 2 (W = W2) is used. According to the first step, an integrated object U in which each of the heat insulation materials 3A and 4A is attached to the load-bearing surface material 2 is formed (see Fig. 1(b)). In the first step, the order of attaching each of the heat insulation materials 3A and 4A to the load-bearing surface material 2 is not particularly limited. For example, each of the heat insulation materials 3A and 4A may be attached to the load-bearing surface material 2 in a predetermined order, or each of the heat insulation materials 3A and 4A may be attached simultaneously.

[0015] In the second step, the outer heat insulation material 3 is formed by cutting and / or machining (hereinafter also referred to as "processing") both sides of the first heat insulation material 3A so that the side edge portion 3a protrudes outside the side edge 2a of the load-bearing surface material 2 (see Fig. 3). The distance L1 between each side edge (3a, 2a) of the outer insulating material 3 and the load-bearing surface material 2 can be set to a value such that a predetermined gap S (a gap twice L1; for example, 0.5 to 2 mm) is formed between the load-bearing surface materials 2 when the first panel material 1A and the second panel material 1B are installed adjacent to each other, as described below. In the second step, the inner heat insulating material 4 is formed by processing the side of the second heat insulating material 4A so as to form a notch 11, which will be described later. In the second step, the order in which the heat insulating materials 3A and 4A are processed does not matter. For example, the heat insulating materials 3A and 4A may be processed in a predetermined order, or the heat insulating materials 3A and 4A may be processed simultaneously.

[0016] In the second process, the first insulating material 3A and the second insulating material 4A are processed in a single work process (see FIG. 1(c)). One work process is a single-pass process in which the one-piece U is placed on a conveyor and transported. In this work process, the one-piece U is placed on the conveyor 6 with the first insulating material 3A facing downward and the second insulating material 4A facing upward. The processing of each of the heat insulating materials 3A, 4A may be carried out while the conveyor 6 is stopped, but from the viewpoint of productivity, it is preferable to carry out the processing while the integral object U is being transported by the conveyor 6.

[0017] In this embodiment, the heat insulating materials 3A and 4A are processed with the integrated object U placed horizontally, but the present invention is not limited to this. For example, the heat insulating materials 3A and 4A may be processed with the integrated object U placed vertically or at an angle. Furthermore, the heat insulating materials 3A and 4A may be processed with the integrated object U placed on a processing table instead of the conveyor 6.

[0018] In the second step, the first insulating material 3A and the second insulating material 4A are machined using a numerically controlled machine tool (i.e., an NC machine tool) such as an NC router into which CAD data for the house blueprints has been input (see Figure 1(c)). The machine tool has a machining head 7 that is movable above the conveyor 6. The machining head 7 has cutting tools 8 for machining each of the insulating materials 3A and 4A.

[0019] In the second step, the first insulating material 3A and the second insulating material 4A are processed based on the position of the load-bearing face material 2 of the one-piece object U. For example, the position of the load-bearing face material 2 of the one-piece object U on the conveyor 6 can be detected by a sensor (not shown) such as a camera, and each of the insulating materials 3A and 4A can be processed based on the position of the load-bearing face material 2 of the one-piece object U.

[0020] According to this manufacturing method for panel material, the first insulating material 3A and the second insulating material 4A are processed in a single process, which allows for efficient manufacturing of the insulating wall panel 1 in which the insulating materials 3 and 4 are attached to both sides of the load-bearing face material 2. More specifically, in this manufacturing method for panel material, the heat insulating materials 3A and 4A are processed in a single pass of the work process in which the unit U is placed on a conveyor 6 and transported. In contrast, if the processing of each insulating material 3A, 4A is carried out within a two-pass work process in which the one-piece U is placed on a conveyor 6 and transported while being turned over, the production efficiency of the panel material 1 will decrease.

[0021] Furthermore, according to this manufacturing method for the panel material, the insulating materials 3A and 4A are pre-cut using a CAD / CAM system. This allows the panel material 1 to be manufactured in the factory with high processing precision, allowing the performance of the load-bearing face material 2 and the insulating materials 3 and 4 to be fully demonstrated. In addition, since each insulation material 3A and 4A can be processed based on the CAD data of the house's blueprint, there is no need for complicated processing work at the construction site, such as cutting the insulation material to fit the dimensions. This also contributes to reducing waste at the construction site and shortening the construction period. Furthermore, insulation construction can be performed without relying on skilled workers.

[0022] <Insulated wall panel material> Next, the panel material 1 obtained by the above-mentioned method for manufacturing a panel material will be described. As shown in Figures 2 and 3, this panel material 1 comprises a load-bearing surface material 2, an outer insulating material 3 provided on one side of the load-bearing surface material 2, and an inner insulating material 4 provided on the other side of the load-bearing surface material 2. In other words, this panel material is a panel material used in a double-sided insulation structure in which an inner insulation material 4 is installed on the inside of a load-bearing surface material 2 and an outer insulation material 3 is installed on the outside, and is a panel material 1 in which the inner insulation material 4 and the outer insulation material 3 are pre-cut.

[0023] The side edge 3a of the outer insulation material 3 protrudes outward beyond the side edge 2a of the load-bearing surface material 2. The side end of the inner insulation material 4 is formed with a notch 11 for fitting with a pillar 21. In addition, the upper and lower ends of the inner insulation material 4 are formed with notches 12 for fitting with cross members 23 such as beams (see Figures 5 and 6). In addition, the middle part of the inner insulation material 4 in the width direction is formed with a notch 13 for fitting with a partition wall 22. The installation positions of each of the notches 11 to 13 are set based on the CAD data of the house blueprint.

[0024] The pillars 21, studs 22, cross members 23, foundations 24, etc. make up the wall skeleton structure 20 of the house (see FIG. 4). The studs 22 are set between a pair of pillars 21, 21 as needed. Furthermore, the reference numeral "29" in FIG. 6 indicates a floor material. Furthermore, because the panels 1 are manufactured using a CAD / CAM system to determine their placement in a house, not all panels used in a house will necessarily have the same configuration. For example, some panels may be shorter in width or length than others, or may have holes for attaching window frames.

[0025] According to this panel material 1, the side edge 3a of the outer insulating material 3 extends outward beyond the side edge 2a of the load-bearing surface material 2, and the side edge of the inner insulating material 4 is formed with a notch 11 for fitting with a pillar 21. This allows the panel material 1 to be installed by fitting the inner insulating material 4 between a pair of pillars 21, 21, and the second panel material 1B can be installed relative to the first panel material 1A so that the outer insulating materials 3 abut against each other and a gap S is formed between the load-bearing surface materials 2 (see Figure 4). Therefore, the force acting due to shaking of the house caused by earthquakes and the like can be released through the gaps S between the load-bearing face panels 2, and high thermal insulation can be ensured by the outer insulation material 3 and the inner insulation material 4. As a result, the performance of the load-bearing face panels 2 and the insulation materials 3, 4 can be fully demonstrated.

[0026] It is difficult to specify in detail from the "insulating wall panel" of the present invention what first and second insulating materials are used and how the first and second insulating materials are processed from the insulating wall panel as a product. In other words, there are circumstances (impossible or impractical circumstances) that make it impossible or impractical to directly specify the insulating wall panel of the present invention based on its structure or properties.

[0027] <House construction method> Next, we will explain the construction method for a house using the above-mentioned panel material 1. As shown in Figure 4, this construction method for a house includes a first step of installing the first panel material 1A by fitting the inner insulation material 4 of the first panel material 1A between the first column 21a and the second column 21b, and a second step of installing the second panel material 1B adjacent to the first panel material 1A by fitting the inner insulation material 4 of the second panel material 1B between the second column 21b and the third column 21c.

[0028] In the first step, the first panel material 1A is installed by fitting the cutout portion 11 into the pillars 21a and 21b, fitting the cutout portion 13 into the partition 22, and fitting the cutout portion 12 into the cross beam material 23 (see Figure 4(a)). In the second step, the second panel material 1B is installed by fitting the cutout portion 11 into the pillars 21b and 21c, fitting the cutout portion 13 into the partition 22, and fitting the cutout portion 12 into the cross beam material 23 (see Figure 4(b)). The installed panel materials 1A, 1B are fixed to the outside of the pillars 21a, 21b, studs 22 and cross beams 23 with screws or nails 25 (see FIG. 7).

[0029] In the second step, the second panel material 1B is installed on the first panel material 1A so that the outer insulating materials 3 abut against each other and a gap S is formed between the load-bearing surface materials 2 (see Figure 4(b)).

[0030] The construction method for this house further includes a step of attaching interior wall materials 26 to the inside of the pillars 21, studs 22, and cross members 23 (see Figure 7). The interior wall materials 27 may be solid walls with the pillars 21 exposed on the surface, or clad walls with the pillars 21 not exposed on the surface. Furthermore, the construction method for this house further includes a step of attaching exterior wall materials 27 to the outside of the panel material 1 via furring strips 28. In addition, in the construction method for this house, the pillars 21, studs 22, cross members 23, etc. may be constructed using a wooden frame construction method.

[0031] According to this house construction method, the second panel material 1B is installed relative to the first panel material 1A so that the outer insulation materials 3 abut against each other, forming a gap S between the load-bearing face materials 2. This allows the gap S to be formed between the load-bearing face materials 2 to release forces acting during an earthquake or the like, and also ensures high thermal insulation through the outer insulation material 3 and the inner insulation material 4. As a result, a house with excellent earthquake resistance and thermal insulation can be constructed efficiently.

[0032] <House> Next, a house 31 equipped with the above panel material 1 will be described. In the house 31, as shown in Fig. 4, the first panel material 1A is installed by fitting the inner insulation material 4 of the first panel material 1A between the first pillar 21a and the second pillar 21b. The second panel material 1B is installed adjacent to the first panel material 1A by fitting the inner insulation material 4 of the second panel material 1B between the second pillar 21b and the third pillar 21c. Furthermore, the outer insulation materials 3 of the adjacent first panel material 1A and second panel material 1B abut against each other, and a gap S is formed between the load-bearing face materials 2.

[0033] The house 31 is constructed using a wooden framework, with a framework of pillars, beams, etc. supporting the load. The load-bearing face material 2 of the panel material 1 is a structural material that bears the force applied to the framework of the house, and by being fixed to the pillars, beams, etc. with nails, it is possible to maintain the framework and suppress distortion of the framework due to shaking from earthquakes, etc. Furthermore, the panel material 1 is pre-cut, that is, it is formed and manufactured in advance in a factory or the like according to the blueprint of the house 31. In addition to the pre-cut panel material 1, the pillars, beams, etc. of the house 31 can also be pre-cut, having been processed and manufactured in advance in a factory or the like according to the blueprint of the house 31.

[0034] In the house 31, the outer heat insulating materials 3 of the adjacent first panel material 1A and second panel material 1B abut against each other, and a gap S is formed between the load-bearing face materials 2. By abutting the outer insulation materials 3 of two adjacent panel materials 1A, 1B against each other, the house 31 can have an insulated structure in which the outside of the house 31 is covered almost without gaps with the outer insulation material 3. As a result, the house 31 has a double-insulated structure consisting of an insulation structure with the outer insulation material 3 that covers the outside almost without gaps, and an insulation structure with the inner insulation material 4, ensuring high insulation properties. Furthermore, in this house 31, because gaps S are formed between the load-bearing face panels 2, when force is applied due to shaking caused by wind, earthquakes, etc., the force can be released, ensuring high earthquake resistance. However, if the load-bearing face panels 2 are in contact with each other, that is, if gaps S are not formed, when force is applied to the load-bearing wall due to shaking caused by wind, earthquakes, etc., distortion occurs between the contacting load-bearing face panels, and the load caused by this distortion is transmitted to the framework of the columns, beams, etc., and the load-bearing wall cannot fully demonstrate its performance.

[0035] It is difficult to identify the "house" of the present invention in detail from the house as a product, such as what first and second insulating materials are used and how the house is equipped with insulating wall panels made from the first and second insulating materials. In other words, there are circumstances (impossible or impractical circumstances) that make it impossible or impractical to directly identify the house of the present invention by its structure or characteristics.

[0036] 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]
