Description

The present invention is a module panel used for constructing a floor, a wall, and a ceiling (roof) of a building, and a panel connection including a floor structure, a wall structure, and a ceiling structure constructed by connecting the module panels. Regarding the design and construction method of the ceremony building.

As a housing construction method, a panel construction method using a wooden panel is known. In the general panel construction method, a wooden frame is constructed at the construction site, and wooden panels with braces are attached to the walls and roof surfaces. Non-Patent Document 1 describes a wooden panel bonding method capable of constructing a house with a wall structure that does not require the construction of a wooden frame on site. In this construction method, large wall panels and roof panels are manufactured by factory production, brought to the site, assembled using heavy machinery, and coupled to each other.

On the other hand, in the design of a house, it is difficult for the general public to imagine a three-dimensionally constructed house from a blueprint drawn by a specialist. A house maker, a contractor, or the like may manufacture a miniature model of a completed house based on a blueprint, for example, so that the owner can imagine the completed house. Patent Document 1 proposes a building design support system using a three-dimensional building model used for this purpose.

Japanese Unexamined Patent Publication No. 2002-31419

In conventional housing construction, a customer (owner) who is thinking of building a house asks a design office, a design contractor such as a house maker, and the design builder draws a blueprint based on the customer's wishes and constructs it. I am following the procedure. Customers' requests for floor plans are often not fully reflected due to structural reasons such as proof stress and strength, or due to reasons such as cost overrun.

In general, the customer does not have sufficient knowledge about the structure, building materials, construction costs, etc., and it is not easy for the customer to design a house with the desired floor plan. In addition, it is not easy to get an estimate of the construction cost of a house designed by oneself without relying on an expert.

If it becomes easier for customers to design the floor plan of a house, for example, with the support of an expert, it will be possible to build a house that more accurately reflects the customer's wishes. Further, for this purpose, it is desirable that the customer can design the floor plan of the house in a form in which the completed house can be easily imagined. Furthermore, it is desirable that the customer can easily understand the estimated construction cost in the process of designing and changing the floor plan without checking with an expert.

In view of these points, an object of the present invention is a panel-connected type that makes it easy for a customer who wants to acquire a house to design a floor plan or the like by himself / herself, and it is easy to understand the appearance and cost after completion. The purpose is to propose a building design and construction method. Further, it is an object of the present invention to provide a module panel used for constructing a panel-connected building having a structure suitable for achieving this purpose.

In order to solve the above problems, the panel connection type building of the present invention adopts the panel construction method, and as a rectangular contour panel used for that purpose, three of the four peripheral panel end faces are convex sides having convex portions. A module panel with a concave end face on one side with a recess on the end face, or a module panel with a concave end face on two adjacent sides with a convex end face and the other adjacent two sides with a recess. use.

At the construction stage, the concave end face of the other module panel is abutted against the convex end face of the module panel, and they are connected and fixed to each other with screw nails or the like. Further, a reinforcing material for connection is sandwiched between the concave end faces of the module panel, the concave end faces of the other module panel are abutted, and they are connected and fixed to each other with screw nails or the like. A floor structure, a wall structure, and a ceiling structure are constructed by connecting the module panels vertically and horizontally, vertically and horizontally, vertically and horizontally. Since the floor, walls, and ceiling are constructed using a common module panel, the types of building materials required to construct these parts can be significantly reduced, and these parts can be constructed easily and efficiently.

In addition, at the design stage, miniature building material parts such as module panels and connecting reinforcements, which are reduced by a certain reduction ratio, are prepared in advance. Ask the customer (owner) to design a building with the desired floor plan using miniature building material parts. That is, by connecting the miniature module panels vertically and horizontally using temporary fixing parts, it is possible to design a floor of the desired size, and by connecting the miniature module panels vertically and horizontally at the desired position, the wall can be designed. Can be designed, and the ceiling (roof) can be designed by connecting miniature module panels vertically and horizontally at the upper end of the wall.

The floor, walls, and ceiling use a common miniature module panel, so you can easily make a miniature building model. Further, by adjusting the number of connected miniature module panels and the connecting direction, it is possible to design the floor plan of the desired building, and it is easy to change the design. Further, since the panel connecting body formed by connecting the miniature module panels is a structure that can withstand a predetermined load, the customer can design the floor plan or the like without being restricted by structural mechanics. Furthermore, from the assembled miniature building model, the customer can easily confirm or imagine the completed building. Therefore, the situation that the completed building does not differ significantly from the intended one does not occur, and the customer can design the building with the floor plan that he / she desires.

A unit price is set in advance for each of the miniature building material parts used to make a miniature building model, and the unit price is multiplied by the same enlargement magnification as the reduction magnification to obtain the actual unit price of the building material. Alternatively, the unit price of the actual building materials is set in advance for each miniature building material part. In the form of a list, for example, it is prepared as data that can be processed by spreadsheet software. While designing, the customer can predict the estimated construction cost after completion based on the type and number of parts used. Therefore, since the customer can design while being aware of the budget, it is convenient because the construction cost greatly exceeds the budget at the estimation stage after the design and the situation where the design is forced to be changed significantly can be avoided.

Hereinafter, embodiments of a panel-connected house design / construction method to which the present invention is applied will be described with reference to the drawings.

(Module panel)
1 (a) is a front view showing a module panel used for construction of a panel-connected house, FIG. 1 (b) is a sectional view thereof, and FIG. 1 (c) is a direction orthogonal to FIG. 1 (b). It is a cross-sectional view of. FIG. 2A is a perspective view of the module panel, and FIG. 2B is an exploded perspective view thereof. The module panel 1 is a panel having a rectangular contour of, for example, 900 mm × 900 mm, which is commonly used for constructing floors, walls, and ceilings of houses. The module panel 1 has a wooden panel frame (core material) 2 having a rectangular contour, a heat insulating material 3 filled in the rectangular opening in the panel frame 2, and 2 attached to both sides of the panel frame 2 to cover the rectangular opening. It is composed of a wooden surface plate 4 having a rectangular contour.

The panel frame 2 is formed by combining four wooden first to fourth frame members 21 to 24 having a rectangular cross section in a rectangular shape. A fifth frame member 25 is bridged between the second and fourth frame members 22 and 24 in a state of extending in parallel with the first and third frame members 21 and 23. These frame members 21 to 25 are connected and fixed to each other by, for example, nails. The first, second, third, and fifth frame materials 21, 22, 23, and 25 are frame materials having the same rectangular cross section. The fourth frame material 24 is a reinforcing frame material having the same width dimension as the first, second, third, and fifth frame materials 21, 22, 23, and 25, but having a larger thickness dimension than these.

The two heat insulating materials 3 have a rectangular parallelepiped shape having substantially the same thickness as the panel frame 2, and are mounted in a state of filling each of the two rectangular openings inside the panel frame 2. For the two surface plates 4, for example, a structural plywood having a thickness of 9 mm is used. Each surface plate 4 is nailed to the first to fourth frame materials 21 to 24 and the fifth frame material 25. Each of the first to fourth panel end faces 11 to 14 on the four circumferences of the module panel 1 is the outer end faces of the first to fourth frame end faces 21a to 24a (the outer end faces of the first to fourth frame materials 21 to 24) on the four circumferences of the panel frame 2. ), And each of the first to fourth plate end faces 41 to 44 on the four circumferences of the two surface plates 4.

The first panel end face 11 is a concave end face in which the first frame end face 21a is retracted inward from the first plate end face 41 by a certain width to form a recess having a certain depth. Similarly, the second panel end face 12 is a concave end face in which the second frame end face 22a recedes inward from the second plate end face 42 to form a recess of a certain depth, and the third panel end face 13 is , The third frame end surface 23a is a concave end surface in which a recess of a certain depth is formed by retracting inward from the third plate end surface 43. On the other hand, the fourth panel end face 14 is a convex end face in which the fourth frame end face 24a protrudes outward from the fourth plate end face 44 by a certain width to form a convex portion having a certain height.

3 (a) to 3 (c) are explanatory views in the case where the module panels 1 are connected in the plane direction. First, in the module panel 1, the direction along the first and third panel end faces 11 and 13 is defined as the first direction H, and the direction orthogonal to the direction is defined as the second direction W. When the module panel 1 is connected in the second direction W, it is a concave end surface of one of the module panels 1 (1) as shown in FIGS. 1 (b), 3 (a), and (b). The third panel end surface 13, which is the concave end surface of the other module panel 1 (2), is abutted against the end surface 11 of one panel with the connecting reinforcing member 5 sandwiched between them. In this state, the edge portion of the surface plate 4 on the first panel end surface 11 is connected and fixed to the connecting reinforcing material 5 by nailing, and the edge portion of the surface plate 4 on the third panel end surface 13 is similarly nailed. It is connected and fixed to the connecting reinforcing material 5.

The connecting reinforcing member 5 is a member having a rectangular cross section, its width dimension is the same as that of the panel frame 2, and its thickness dimension is from twice the depth of the recesses of the first and third panel end faces 11 and 13. Is also slightly larger. Therefore, in a state where the module panels 1 (1) and 1 (2) are connected in the second direction W, as shown in FIG. 3 (c), both module panels 1 (1) and 1 (2) are respectively. The connecting reinforcing material 5 is covered with the surface plate 4 to form a flat surface.

When the module panel 1 is connected in the first direction H, as shown in FIGS. 1 (c) and 3 (a), the fourth panel end surface 14 which is the convex end surface of one of the module panels 1 (1). Is inserted into the concave portion of the second panel end surface 12 which is the concave end surface of the other module panel 1 (3), and the second and fourth panel end surfaces 12 and 14 are butted against each other. In this state, the edge portion of the surface plate 4 on the side of the module panel 1 (3) is connected and fixed to the thick fourth frame member 24 which is the reinforcing frame plate on the side of the module panel 1 (1) by nailing. ..

The fourth frame material 24, which is a reinforcing frame plate, is a plate having a rectangular cross section having the same dimensions as the connecting reinforcing material 5. When the module panels 1 (1) and 1 (3) are connected in the first direction H, as shown in FIG. 3 (c), the surface plates of both module panels 1 (1) and 1 (3) are respectively. The fourth frame member 24 is obscured by 4 to form a flat surface.

FIG. 4 is an explanatory diagram showing a case where the module panels 1 are connected in an orthogonal state. For example, in the case of forming a corner portion of an outer wall of a building, as shown in this figure, a first panel end surface 11 which is a concave end surface of one module panel 1 (4) and the other module panel 1 (5). ), Which is the concave end face of the third panel, is positioned so as to be orthogonal to each other. Two types of L-shaped flat joint corner parts 6a and 6b are attached to the rectangular gap formed in the corner portion. Corner parts 6a and 6b for flat joints are assembled and fixed by nailing to form a hollow prism at the corner, and both module panels 1 (4) and 1 (5) are connected by nailing here. Fix it. Further, the inside of the hollow prism is filled with the heat insulating material 7.

Here, as the module panel 1, a module panel having half the width dimension or the height dimension is also used. 5 (a) and 5 (b) are a front view and a cross-sectional view showing a module panel 1A having a dimension of half in the first direction H. Since the basic configuration is the same as that of the module panel 1, the corresponding parts are designated by the same reference numerals in the drawings, and the description of these parts will be omitted.

(How to design and construct a panel-connected house)
An example of a design and construction method of a panel-connected house using the above-mentioned module panels 1, 1A and a connecting reinforcing material 5 will be described. FIG. 6A is a perspective view showing a position example of a panel-connected house, and shows a state before finishing such as wall finishing. FIG. 6B (a) is a cross-sectional view in the short side direction thereof, and FIG. 6B (b) is a cross-sectional view in the long side direction thereof.

The panel-connected house 100 (hereinafter, may be simply referred to as “house 100”) includes a floor structure 110, an outer wall structure 120, and a ceiling configured by using the module panels 1, 1A, and the connecting reinforcing material 5. It is provided with a rectangular housing body composed of a structure 130. The main body of the house is installed on a steel-framed base holder 142 overlaid on the foundation 140. For example, a one-way roof 150 is installed on the ceiling structure 130 of the main body of the house.

In the foundation portion 140, for example, RC independent foundations 141 are installed at predetermined intervals along the outer wall installation position of the house 100, and are installed at predetermined positions inside the RC independent foundation 141, and a steel-framed foundation support 142 such as H-shaped steel is provided. It is arranged along the outer wall installation position and supported by an independent foundation 141. Horizontal members 143 such as steel square pipes are laid in the short side direction at predetermined intervals between the base supports 142 that are laid in the long side direction. Further, if necessary, an elastic member 144 such as seismic isolation rubber is mounted between the foundation portion 140 and the base holder 142. Various structures can be adopted as the basic structure, and the structure is not limited to the configuration of this example.

FIG. 7 is a plan view of the first floor of the panel-connected house 100, and shows an example of allocation of the module panels 1 and 1A of the floor structure 110. In this example, the module panels 1 and 1A are connected so that the connecting reinforcing member 5 extends in the long side direction. Further, the panel rows adjacent to the short side direction are arranged in a staggered arrangement with respect to the one row of panel rows extending in the long side direction. Further, a portion having dimensions that cannot be handled by the module panels 1 and 1A may occur in the long side direction and the short side direction. In this case, the adjustment panels 111 and 112 are connected by on-site construction. Similar to the module panels 1 and 1A, the adjusting panels 111 and 112 have a structure in which connecting reinforcing materials are passed through both sides, surface plates made of long structural plywood are attached to the top and bottom, and a heat insulating material is filled inside. Is.

An example of allocation on the short side of the outer wall structure 120 is shown in FIG. 6B (a), and an example of allocation on the long side is shown in FIG. 6B (b). An adjustment panel 121 by on-site construction is attached to the lower end portion of the outer wall structure 120. Similar to the module panels 1 and 1A, the adjusting panel 121 is composed of upper and lower connecting reinforcing materials, a heat insulating material filled between them, and surface plates attached to both sides. The connecting reinforcing material at the lower end of the adjusting panel 121 is fixed to the base holder 142 by the connecting bolts welded to the base holder 142. Further, a connecting member 113 is attached to a recess on the concave end surface of the module panel 1 of the floor structure 110 at a portion of contact with the floor structure 110, and both are connected and fixed by nailing through the connecting member 113. In the illustrated outer wall structure 120, window frames 125 and 126 are attached to the four circumferences, respectively.

The panel allocation of the ceiling structure 130 is basically the same as that of the floor structure 110. As shown in FIG. 6B (b), the ceiling structure 130 is supported by a plywood beam 131 extending in the short side direction between the upper ends of the outer wall structure 120. The plywood beam 131 is passed along the panel allocation so as to be located directly below the connecting reinforcing member 5. Further, the four peripheral portions of the ceiling structure 130 are connected and fixed to the upper end portion of the outer wall structure 120 via a connecting member 132 by nailing.

Next, in the design stage of the panel-connected house 100 having this structure, a building material including a module panel 1, 1A, a connecting reinforcing material 5, a flat joint corner parts 6a, 6b, a window frame 125, 126, and an adjusting panel. Prepare a miniature building material parts set including miniature building material parts having dimensions reduced by a certain reduction ratio and temporary fixing parts that can temporarily fix these miniature building material parts to each other in the plane direction and the orthogonal direction. For example, magnetic force can be used to temporarily fix parts. For example, if the concave end face and the convex end face of the miniature module panel are set as different magnetic poles, they can be easily connected.

Using the miniature building material parts set, ask the owner to make a miniature building model with floors, walls and ceilings arranged according to the desired layout. Since the floor, wall, and ceiling structure of the actual house 100 is basically composed of module panels 1 and 1A, it is actually constructed using miniature building material parts, unlike the case where columns and beams are arranged. The floor plan and the like are designed through the work of producing a miniature house model with a layout of the structure corresponding to the house 100 to be constructed. By repeating the work of changing the floor, wall, and ceiling layout of the miniature building model produced, the owner can determine (design) the floor, wall, ceiling, or roof layout of the panel-connected building to be actually built.

Here, a unit price for estimating the construction cost is assigned to the miniature building material parts in advance so that the construction cost can be calculated using spreadsheet software or the like. The actual number of miniature building material parts that make up the floor, walls, and ceiling of a miniature building model is multiplied by the unit price for integration assigned to each miniature building material part, and the multiplication result is added. Approximate construction costs for floors, walls, and ceilings can be calculated. The owner can design the layout of the house using miniature building material parts while checking the approximate construction cost.

[Another example of module panel]
8 (a) to 8 (d) are a front view showing another configuration example of the module panel 1, a cross-sectional view when cut in two orthogonal directions, and an explanatory view showing how to connect. The module panel 200 of this example is also a panel having a rectangular contour used for constructing a floor, a wall, and a ceiling of a building such as a house. The module panel 200 is an elongated rectangular panel, for example, having a short side of 450 mm and a long side of 2700 mm.

A panel frame 220 formed by combining four first to fourth wooden frame materials 221 to 224 having a rectangular cross section in a rectangular shape, a heat insulating material 230 filled in a rectangular opening of the panel frame 220, and both sides of the panel frame 220. It comprises woody first and second surface plates 240 that are attached to the surface and cover the rectangular opening. In the panel frame 220, the second frame material 222 on the short side side and the third frame material 223 on the long side side are frame materials having the same cross section. The first frame material 221 on the long side and the fourth frame material 224 on the short side have the same width as the second and third frame materials 222 and 223, but the reinforcing frame material has a larger thickness than these. Is.

The first to fourth panel end faces 211 to 214 on the four circumferences of the module panel 200 are the first to fourth frame members 221 to the panel frame 220 located at positions corresponding to the first to fourth panel end faces 211 to 214, respectively. It is composed of each of the first to fourth frame end faces 221a to 224a of the 224 and each of the first to fourth plate end faces 241 to 244 on each of the four circumferences of the two surface plates 240.

In the first panel end surface 211 composed of the first frame end surface 221a and the first plate end surface 241 the first frame end surface 221a protrudes outward by a certain width from the first plate end surface 241 to form a convex portion having a constant height. It is a convex side end face. In the second panel end surface 212 composed of the second frame end surface 222a and the second plate end surface 242, the second frame end surface 222a is retracted inward from the second plate end surface 242 by a certain width, and a recess of a certain depth is formed. It is a formed concave end face. In the third panel end surface 213 composed of the third frame end surface 223a and the third plate end surface 243, the third frame end surface 223a recedes inward from the third plate end surface 243 by a certain width to form a recess of a certain depth. It is a concave end face. The fourth panel end face 214 composed of the fourth frame end face 224a and the fourth plate end face 244 is a convex end face on which the fourth frame end face 224a projects outward from the fourth plate end face 244 to form a convex portion. ..

The direction along the first and third panel end faces 211 and 213 is the first direction H, and the direction orthogonal to this is the second direction W. When the module panel 200 is connected in the second direction W, as shown in FIG. 8D, the convex portion of the first panel end surface 211, which is the convex side end surface of one module panel 200 (1), is connected to the other. The module panel 200 (2) can be inserted into the concave portion of the third panel end surface 213, which is the concave end surface of the module panel 200 (2), and these end faces can be butted and fixed to each other. Similarly, when the module panel 200 is connected in the first direction H, the concave side of the second panel end surface 212, which is the concave end surface of one module panel 200, and the convex side of the other module panel (not shown). The convex portions of the end face 214 of the fourth panel, which is the end face, can be inserted, and these end faces can be butted and fixed to each other.

When the module panel 200 of this example is used, the connecting reinforcing material 5 used when connecting the module panels 1 and 1A in the second direction W becomes unnecessary. Therefore, the work for connecting the panels to construct the floor structure, the wall structure, and the ceiling structure can be efficiently performed.
