Description

  The present invention relates to an outer wall structure of a building.

  As a building such as a house, there is a unit type building configured by combining a plurality of rectangular parallelepiped building units. The building unit is manufactured at a factory, then transported to a building site, and installed at the building site to constitute a building.

  In the unit type building, the outer wall may protrude upward from the building unit due to having an inclined roof such as a single-flow roof. For example, the protrusion part of an outer wall may be formed by the outer wall panel being provided above the side part of a building unit (refer patent document 1). In this configuration, the building units and the outer wall panels are arranged one-on-one vertically, and the same number of outer wall panels as the building units are arranged side by side in the width direction of the outer wall.

JP 2002-371630 A

  However, in the configuration in which the building unit and the outer wall panel are arranged one by one vertically, the outer wall panel has the same width dimension as the building unit, so if the width dimension is different for each building unit, It is necessary to use a dedicated outer wall panel that matches the width of the building unit for each building unit. In this case, there is a concern that the work burden and cost burden at the time of constructing the outer wall portion may increase, for example, there is a possibility that all the outer wall panels have to be dedicated.

  This invention is made | formed in view of the said situation, and makes it the main objective to construct | assemble the outer wall part of a unit type building suitably.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, for easy understanding, the corresponding configuration in the embodiment of the invention is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

  The outer wall structure of the building of the first invention is applied to a unit type building configured by combining a plurality of building units (building units 20), and the outer wall part (girder side wall part 16a) of the unit type building is the building. A building outer wall structure including a unit side surface portion (outer wall forming portion 43) of the unit, wherein the outer wall portion includes a plurality of outer wall panels (upper side wall panels) provided side by side above the unit side surface portion. 42), and the plurality of outer wall panels include a module wall panel (intermediate wall panel 42c) having a width dimension that is an integral multiple of a predetermined module dimension, and an integral multiple of the module dimension. Special-size wall panels (protruding corner wall panels 42a and straddling wall panels 42b) having different width dimensions are included.

  According to the first aspect of the present invention, in the configuration in which the module wall panel as the outer wall panel is provided on the upper side of the unit side surface, the width dimension of the module wall panel is set to an integral multiple of the module dimension. The panel need not be a dedicated product having the same width as the building unit. In addition to the module wall panel, a special wall panel is also included in the outer wall part. Therefore, by using the special wall panel as a special product having a width dimension different from an integral multiple of the module dimension, the outer wall part can be used. It can be avoided that the width dimension is limited to an integral multiple of the module dimension.

  Moreover, in a unit type building, when the width dimension of an outer wall part is changed by changing the width dimension of a building unit, it will be necessary to change the width dimension and installation number of an outer wall panel. In this case, it is possible to respond to changes in the width dimension of the outer wall by changing the width dimension and the number of installation of the module wall panel without changing the width dimension and the number of installation of the special-size wall panel as a special product. Is possible. Here, the special size wall panel is a special product with low versatility because its width dimension is not an integral multiple of the module dimension, so when changing the width dimension or number of installation of this special size wall panel There is a concern that work burden and cost burden are large. On the other hand, since the module wall panel has high versatility because its width dimension is an integral multiple of the module dimension, the work burden and cost burden when manufacturing the module wall panel can be reduced.

  By the above, the outer wall part of a unit type building can be constructed suitably.

  In 2nd invention, in 1st invention, the spanning wall panel (stranding wall panel 42b) which straddles the unit boundary part between the said building unit which adjoins horizontally is provided as the said special size wall panel.

  According to the 2nd invention, even when the width dimension of an outer wall part is changed, it is not necessary to change the relative position of the straddle wall panel with respect to the boundary part of an adjacent building unit. In this case, the installation position of the module wall panel can be easily set by using the position of the straddling wall panel as the special-size wall panel as a reference. In this case, since it is not necessary to change the positional relationship between the area where the straddle wall panel is installed and the area where the module wall panel is installed, the module wall panel and the straddle wall panel are adjusted in accordance with the change in the width of the outer wall. It is possible to save the trouble of newly setting the arrangement order.

  According to a third aspect, in the second aspect, at the unit boundary portion, a vertical joint (unit vertical joint 61) between adjacent unit side portions is directed downward from an intermediate position of the special size wall panel. It extends.

  At the unit boundary, a vertical joint formed between adjacent unit side surfaces (hereinafter referred to as a unit vertical joint) and a vertical joint formed between adjacent outer wall panels (hereinafter referred to as a panel vertical joint). When arranged vertically, the unit vertical joint and the panel vertical joint intersect with the horizontal joint formed between the unit side surface portion and the outer wall panel in a cross shape. In this case, both the waterproof process for the upper end of the unit vertical joint and the waterproof process for the lower end of the panel vertical joint are performed at the cross-shaped intersection, and the configuration of these waterproof processes may be complicated. Concerned.

  On the other hand, according to the third invention, since the panel vertical joint formed by the special-size wall panel is arranged at a position shifted to the left and right with respect to the unit vertical joint, these vertical joints are the horizontal joints. The crossing portion of the vertical joint of the panel does not have a cross shape, and the waterproof treatment for the lower end of the panel vertical joint and the waterproof treatment for the upper end of the unit vertical joint can be performed at different locations. Thereby, the waterproof process with respect to a vertical joint can be easily performed in an outer wall part.

  In 4th invention, in 2nd or 3rd invention, the width dimension of the said straddle wall panel is a value smaller by 1/2 of this module dimension than the integral multiple of the said module dimension.

  According to the fourth invention, the width dimension of the straddling wall panel has regularity that the module dimension x 1/2 is smaller than the integral multiple of the module dimension. The design and members for manufacturing the module wall panel are easily diverted. For this reason, the work burden and cost burden at the time of manufacturing a straddle wall panel can be reduced.

  In a fifth invention, in any one of the first to fourth inventions, an end wall panel (protruding corner wall panel 42a) that forms an end of the outer wall portion is provided as the special-size wall panel. .

  According to the fifth invention, even when the width dimension of the outer wall portion is changed, it is not necessary to change the relative position of the end wall panel with respect to the protruding corner portion or the entering corner portion (end portion of the outer wall portion) of the outer wall. . In this case, the installation position of the module wall panel can be easily set by using the position of the end wall panel as the special-size wall panel as a reference. In addition, since there is no need to change the positional relationship between the area where the end wall panel is installed and the area where the module wall panel is installed, the module wall panel and the end wall panel It is possible to save the trouble of newly setting the arrangement order.

  According to a sixth aspect, in the fifth aspect, the width dimension of the end wall panel is a value smaller by a quarter of the module dimension than an integral multiple of the module dimension.

  According to the sixth aspect of the invention, the end wall panel is manufactured because the width dimension of the end wall panel has regularity that is smaller than the integral multiple of the module dimension by the module dimension x 1/4. In some cases, the design and members for manufacturing the module wall panel can be easily used. For this reason, the work burden and cost burden at the time of manufacturing an end part wall panel can be reduced.

  In 7th invention, in 6th invention, the width dimension of the said edge part wall panel is smaller than the said module dimension. In other words, the width dimension of the end wall panel is a value smaller by a quarter of the module dimension than the module dimension.

  According to the seventh aspect, since the end wall panel is downsized, it is possible to further reduce the work burden and the cost burden when manufacturing the end wall panel. Further, for example, even if the end wall panel has a pair of wall panel portions extending in a direction intersecting each other to form a corner portion of the building, the end wall panel is An increase in size can be suppressed. In addition, about the edge part wall panel which has a pair of wall panel part, the width dimension of one wall panel part will be considered as the width dimension of this edge part wall panel.

  In an eighth invention according to any one of the first to seventh inventions, the special-size wall panels are arranged on both side end portions of the side surface portion of the unit so that the distance between them is an integral multiple of the module size. The module wall panels having a width dimension corresponding to the separation distance are provided between the special size wall panels, which are arranged on the respective upper sides.

  According to the eighth invention, since the special size wall panel is arranged above each of the adjacent columns in the building unit, the special size wall with respect to the column of the building unit even when the width dimension of the outer wall portion is changed. There is no need to change the relative position of the panel. In this case, the installation position of the module wall panel can be easily set by using the position of the special wall panel as a reference. In this case, it is not necessary to change the positional relationship between the area where the special wall panel is installed and the area where the module wall panel is installed. This saves you the trouble of setting a new arrangement order with the wall panel.

  According to a ninth invention, in any one of the first to eighth inventions, the outer wall panel extends in an up-down direction with an outer wall surface material (outer wall surface material 32) forming an outer wall surface of the outer wall portion. A plurality of vertical base materials (vertical base materials 34) that are arranged in the width direction of the outer wall portion and support the outer wall surface material, and the outer wall portions are spaced between adjacent vertical base materials. Has a module area (module area S1) having the module dimensions and a special dimension area (special dimension area S2) in which the interval between the adjacent vertical base materials is different from the module dimensions, The special size region is included in the special size wall panel among the module wall panel and the special size wall panel.

  According to the ninth aspect, since the special dimension region is included in the special dimension wall panel, the vertical base material can be arranged at equal intervals for each module dimension in the module wall panel. For this reason, the work burden and cost burden at the time of manufacturing a module wall panel can be reduced more reliably. Also, if the special wall panel has a module area in addition to the special wall area, when the special wall panel is manufactured, the design and members for configuring the module area are shared with the module wall panel. Therefore, it is possible to more reliably reduce the work burden and cost burden when manufacturing a special-size wall panel.

For example, in the protruding corner wall panel 42a arranged at the connection portion between the girder side wall portion 16a and the end side wall portion 16b, one of the pair of wall panel portions is included in the girder side wall portion 16a, and the other is the end side wall portion 16b. Included.

  Among the plurality of upper side wall panels 42, the one included in the girder side wall portion 16 a is formed in a rectangular shape due to the upper end portion of the girder side wall portion 16 a extending in the horizontal direction. What is included in 16b is formed in a trapezoidal shape or a triangular shape due to the inclination of the upper end portion of the wife side wall portion 16b. Incidentally, in the protruding corner wall panel 42a, the wall panel portion of the pair of wall panel portions included in the girder side wall portion 16a is formed in a rectangular shape, but is included in the wife side wall portion 16b. The wall panel portion on the side is formed in a trapezoidal shape.

  In both the girder side wall portion 16a and the end side wall portion 16b, an upper vertical joint 62 extending upward from the second-floor horizontal joint 45 is formed between the adjacent upper side wall panels 42, and each upper side wall panel 42 is arranged so that the upper vertical joint 62 and the unit vertical joint 61 do not line up and down.

  The unit vertical joint 61 and the upper vertical joint 62 are provided with a waterproof member such as a gasket or a sealing material. In particular, in the upper vertical joint 62, a waterproof member is pressed between the outer wall surfaces 32 of the adjacent upper wall panels 42, and a waterproof sheet 64 (see FIG. 3A) covers the waterproof member from the indoor side. ) Is provided in a state of being hung on the indoor side surface of each outer wall surface material 32. The waterproof sheet 64 extends in the wall width direction along the second floor horizontal joint 45, and the upper side wall panel 42 is overlaid on the indoor side surface of the outer wall surface material 32, while the unit wall panel 41 is It is overlaid on the outdoor side surface of the outer wall surface material 32.

  In the waterproof sheet 64, it is in a state of entering the upper vertical joint 62 toward the indoor side, so that a fold or a bend is formed in an extended portion extending downward from the lower end portion of the upper vertical joint 62. There is a concern that water such as rainwater may enter the indoor side of the waterproof sheet 64 through the folds or bends. Here, when the unit vertical joint 61 and the upper vertical joint 62 are arranged vertically, the extending portion of the waterproof sheet 64 is attached to the waterproof member in the unit vertical joint 61 at a position below the upper vertical joint 62. However, due to the fact that the outdoor side surface of the waterproof member is not flush with the outer wall surface of the unit wall panel 41, the extended portion of the waterproof sheet 64 and the waterproof member in the unit vertical joint 61 are A gap is easily formed between them. For this reason, in the part where the waterproof sheet 64 is overlapped with the waterproof member in the unit vertical joint 61, there is a further concern that water may enter the outdoor side of the waterproof sheet 64.

  On the other hand, in the present embodiment, the unit vertical joint 61 and the upper vertical joint 62 are arranged at positions shifted to the left and right, so that the extending portion of the waterproof sheet 64 is provided at a position below the upper vertical joint 62. The outer wall surface 32 of the unit wall panel 41 can be overlaid on the outdoor surface. For this reason, in the waterproof sheet 64, even if a crease or a bend occurs in the extended portion extending downward from the lower end portion of the upper vertical joint 62, the extended portion is against the outer wall surface of the unit wall panel 41. By being affixed appropriately, water can be prevented from entering the indoor side of the waterproof sheet 64 through the folds and flexures.

  In the girder side wall portion 16a, a plurality of upper side wall panels 42, a straddling wall panel 42b straddling the unit vertical joint 61 (docking line DL) on the left and right, and an intermediate wall panel disposed at a position not straddling the docking line DL 42c. In the girder side wall portion 16a, a straddling wall panel 42b is disposed between the protruding corner wall panels 42a disposed at both end portions thereof, and the intermediate wall panel 42c includes the protruding corner wall panel 42a and the straddling wall panel 42b. It is arranged between. The docking line DL passes through the center of the straddling wall panel 42b.

With respect to the protruding corner wall panel 42a, the straddling wall panel 42b, and the intermediate wall panel 42c, the respective width dimensions are set based on a predetermined module dimension M (for example, 500 mm). The width dimension Wa of the protruding corner wall panel 42a, the width dimension Wb of the straddling wall panel 42b, and the width dimension Wc of the intermediate wall panel 42c are:
Wa = M × p−M × 1/4 (1)
Wb = M × q−M × 1/2 (2)
Wc = M × r (3)
It is set to the value calculated by the formula. Note that p, q, and r are positive integers. The module dimension M can also be referred to as a reference dimension.

  According to the equation (3), the width dimension Wc of the intermediate wall panel 42c is a positive integer multiple (natural number multiple) of the module dimension M, and the intermediate wall panel 42c corresponds to a module wall panel. Further, according to the equation (1), the protruding corner wall panel 42a has a value smaller by a quarter of the module dimension M than the positive integral multiple of the module dimension M, and the width dimension Wb of the straddling wall panel 42b. Is a value smaller by a half of the module dimension M than a positive integer multiple of the module dimension M. In this case, the protruding corner wall panel 42a and the straddling wall panel 42b correspond to special-size wall panels. Further, the protruding corner wall panel 42a corresponds to an end wall panel disposed at a side end portion of the girder side wall portion 16a.

  At least one intermediate wall panel 42c is disposed between the protruding corner wall panel 42a and the straddling wall panel 42b. Accordingly, the separation distance between the protruding corner wall panel 42a and the straddling wall panel 42b is a value obtained by multiplying the width dimension Wc of the intermediate wall panel 42c by a positive integer, that is, a value obtained by multiplying the module dimension M by a positive integer. It has become.

Further, in the girder side wall portion 16a, the width dimension Wd of the outer wall forming portion 43 of the building unit 20 is also set based on the module dimension M. This width dimension Wd is
Wd = M × s−M × 1/4 (4)
It is set to the value calculated by the formula. Note that s is a positive integer.

  In the spar side wall portion 16a of the present embodiment, the width dimensions Wa and Wb of the protruding corner wall panel 42a and the straddling wall panel 42b are set regardless of the width dimension Wd of the outer wall forming portion 43. For example, the protruding corner wall panel 42a is set to Wa = 375 mm because p in the equation (1) is 1. Further, the straddling wall panel 42b is set to Wb = 1750 mm because q in the expression (2) is 4.

  Incidentally, the width dimension Wa of the protruding corner wall panel 42a is set to a value smaller than the module dimension M. That is, as described above, p in the equation (1) is 1. For this reason, even if the protruding corner wall panel 42a has a pair of wall panel portions orthogonal to each other, it is possible to suppress an increase in size. Thereby, a work burden can be reduced at the time of carrying work or attaching work to a building frame. In the protruding corner wall panel 42a, the width dimension of the portion included in the end wall part 16b is set to a value (for example, 250 mm) smaller than the width dimension Wa.

  The number and width dimensions of the intermediate wall panels 42c are set according to the width dimension Wb of the outer wall forming portion 43. For example, as shown in FIG. 4, when two outer wall forming portions 43A and 43B are arranged side by side and the width dimension Wd1 of the outer wall forming portion 43A is larger than the width dimension Wd2 of the outer wall forming portion 43B, the upper side of the outer wall forming portion 43A. And the number of installed intermediate wall panels 42c differ between the upper side of the outer wall forming portion 43B. The outer wall forming portions 43A and 43B are set to Wd1 = 4750 mm and Wd2 = 3250 mm because s in Equation (4) is 10 and 7, respectively.

  Two intermediate wall panels 42c are disposed above the outer wall forming portion 43A, and one intermediate wall panel 42c is disposed above the outer wall forming portion 43B. The intermediate wall panel 42c on the upper side of the outer wall forming portion 43B has a width dimension Wc1, and one of the two intermediate wall panels 42c on the upper side of the outer wall forming portion 43A has the same width dimension Wc1, and the other is It has a width dimension Wc2. The width dimension Wc1 is set to Wc1 = 2000 mm because r in the expression (3) is 4. Also, the width dimension Wc2 is set to Wc2 = 1500 mm because r in the expression (3) is 3.

  Incidentally, the width dimension Wb of the straddling wall panel 42b and the width dimension Wc of the intermediate wall panel 42c are set to values smaller than the width dimension We (for example, 2500 mm) of the short side portion of the building unit 20. Here, the upper side wall panel 42 is loaded on a truck together with the building unit 20 and is transported. Depending on the height dimension of the girder side wall portion 16a, the height dimension of the upper side wall panel 42 may be road traffic in the width direction of the truck. It is assumed that the legal transport limit will be exceeded. Therefore, the spanning wall panel 42b and the intermediate wall panel 42c can be properly transported by truck by setting their width dimensions Wb and Wc to values that do not exceed the transport limit in the width direction of the truck. .

  As shown in FIG. 5, in the girder side wall portion 16 a, the intermediate wall panel 42 c is arranged at a position where it does not overlap with each pillar 21 of the building unit 20 in the front view. Here, the width dimension of the column 21 is set to a value smaller than the module dimension M × 1/4 (for example, 125 mm), and the column 21 arranged on the back side of the protruding corner wall panel 42a in the plan view has its output. It arrange | positions in the position which does not protrude to the side from the corner wall panel 42a. Further, the pillar 21 disposed on the back side of the straddling wall panel 42b in plan view is disposed near the center of the straddling wall panel 42b, and the width Wb of the striding wall panel 42b is larger than the module dimension M. The wall panel 42b does not protrude laterally.

  Each upper side wall panel 42 has the outer wall surface material 32 and the outer wall base 33, respectively, and the adjacent upper wall panel 42 is mutually fixed by connecting each outer wall base 33. FIG. For example, in the straddling wall panel 42b and the intermediate wall panel 42c, as shown in FIGS. 6 (a) and 6 (b), a pair of upper and lower horizontal base materials 35 and 36 and the ends of the horizontal base materials 35 and 36 are connected to each other. A frame 33a on a rectangular frame is formed by a pair of left and right vertical members 34a connecting the two. In the frame 33a, a pair of left and right vertical members 34a form a vertical frame portion, an upper horizontal base material 35 forms an upper frame portion, and a lower horizontal base material 36 forms a lower frame portion. The width dimension of the body 33a is the same as the width dimensions Wb and Wc of the wall panels 42b and 42c.

  About the adjacent upper side wall panel 42, the vertical member 34a of each frame 33a is mutually connected by the volt | bolt etc. in the state piled up right and left. In this case, the vertical members 34a of the adjacent upper side wall panels 42 form one vertical base material 34 in a state of being connected to each other. These vertical members 34a are connected by bolt members penetrating the webs in a state where the outer surfaces of the respective webs are overlapped with each other.

  Moreover, each frame 33a of the adjacent upper side wall panel 42 is connected also by connection members 65, such as a metal plate. The connecting member 65 is provided on each of the upper part and the lower part of the frame 33a, and the connecting member 65 provided on the upper part is stretched over the upper horizontal base material 35 of each frame 33a and provided on the lower part. The connecting member 65 is stretched over the lower lateral base material 36 of each frame 33a.

  The wall panels 42b and 42c have the vertical base material 34 arrange | positioned inside the frame 33a. The vertical base material 34 is provided between a pair of left and right vertical materials 34 a and connects a pair of upper and lower horizontal base materials 35 and 36. The installation interval of the vertical base material 34 including the vertical base material 34 formed by the pair of left and right vertical members 34a is set based on the module dimension M.

  For example, in the intermediate wall panel 42c, as shown in FIG. 6A, the vertical base material 34 is disposed at equal intervals so that the installation interval of the vertical base material 34 becomes the module dimension M. In this case, if an area where the installation interval of the vertical base material 34 is the module dimension M is a module area S1, the module area S1 calculates the width dimension Wc of the intermediate wall panel 42c. S1 is arranged side by side. In this case, if the number of module regions S1 is changed, the width dimension Wc of the intermediate wall panel 42c increases or decreases. Therefore, the intermediate wall panel 42c can be used as a general-purpose product with a small work burden and cost burden in manufacturing. ing.

  Further, in the straddling wall panel 42b, as shown in FIG. 6B, in addition to the module region S1, a special size region S2 in which the installation interval of the vertical base material 34 is made smaller than the module size M is arranged. Yes. The width dimension of the special dimension area S2 (the interval between the vertical base materials 34) is ½ of the module dimension M, and the special dimension area S2 is disposed between the adjacent module areas S1. The total number of module regions S1 and special size regions S2 arranged on the straddling wall panel 42b is the same as q in the equation (2) for calculating the width dimension Wb of the straddling wall panel 42b. The width dimension of the special dimension area S2 is smaller than the module area S1 by a predetermined value (1/2 of the module dimension M). In this case, the straddling wall panel 42b has a special size region S2 and can be used as a special product.

  In the upper side wall panel 42, a plurality of fixing brackets 55 are arranged side by side along the lower lateral base material 36. These fixing brackets 55 are basically arranged at positions that do not line up and down on the vertical base material 34 and are arranged at equal intervals so that the installation interval becomes the module dimension M.

  For example, in the intermediate wall panel 42c, as shown in FIG. 6A, the installation interval of all the fixing brackets 55 is the module dimension M. Further, the fixing bracket 55 is disposed at the center position of the adjacent vertical base materials 34, and the separation distance to these vertical base materials 34 is ½ of the module dimension M. Here, when the two intermediate wall panels 42c are arranged adjacent to each other, the distance between the fixing brackets 55 that are adjacent to each other with the boundary portion between the intermediate wall panels 42c is ½ of the module dimension M. .

  On the other hand, in the straddling wall panel 42b, the installation interval of the fixing bracket 55 is not the module dimension M as shown in FIG. Among the plurality of fixing brackets 55, the fixing brackets 55 adjacent to each other with the docking line DL interposed therebetween are arranged at positions where the mutual separation distance becomes the module dimension M × 1.5. The separation distance is set to a value larger than the total width dimension of the adjacent columns 21, and the fixing bracket 55 does not need to be fixed to the upper end portion of the columns 21. Here, the adjacent building units 20 are connected by the docking plates being laid across the pillars 21, and the docking plates are superimposed on the upper end surfaces of the pillars 21 from above. As described above, since the docking plate is fixed to the upper end portion of the column 21, it is difficult to properly fix the fixing bracket 55 to the upper end portion of the column 21.

  Further, in the straddling wall panel 42b, the separation distance between the fixed bracket 55 arranged next to the vertical frame portion (vertical member 34a) of the frame 33a and the vertical frame portion among the plurality of fixed brackets 55 is determined by the module. It is set to 1/2 of the dimension M. For this reason, when the intermediate wall panel 42c and the straddling wall panel 42b are adjacent to each other, the separation distance between the fixing brackets 55 adjacent to each other across the boundary between the wall panels 42c and 42b is the module dimension M. In this case, except for the fixing brackets 55 that are adjacent to each other with the docking line DL interposed therebetween, the fixing brackets 55 are arranged with the module dimension M as the installation interval in the girder side wall portion 16a.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In addition to the intermediate wall panel 42c that can be used as a general-purpose product, a protruding corner wall panel 42a and a straddling wall panel 42b that can be used as special products are included in the girder side wall portion 16a. It is possible to avoid being limited to an integral multiple of the module dimension M. Moreover, when the width dimension of the girder side wall part 16a is changed by changing the width dimension of the building unit 20, the width dimension and the number of installation of the projecting corner wall panel 42a and the straddling wall panel 42b need not be changed. In addition, by changing the width dimension and the number of installation of the intermediate wall panel 42c, it is possible to cope with the change in the width dimension of the girder side wall portion 16a. Moreover, since the intermediate wall panel 42c can be used as a general-purpose product, it is possible to reduce the work burden and cost burden when manufacturing the intermediate wall panel 42c.

  Since the striking wall panel 42b, not the intermediate wall panel 42c, is arranged at a position straddling the docking line DL, the relative position of the straddling wall panel 42b with respect to the docking line DL is changed even when the width dimension of the girder side wall portion 16a is changed. There is no need to do. For this reason, the installation position of the intermediate wall panel 42c can be easily set by using the position of the straddling wall panel 42b as a reference.

  Further, since the protruding corner wall panel 42a, not the intermediate wall panel 42c, is arranged at the end portion of the girder side wall portion 16a, even when the width dimension of the girder side wall portion 16a is changed, There is no need to change the relative position of the corner walls. For this reason, the installation position of the intermediate wall panel 42c can be easily set by using the position of the protruding corner wall panel 42a as a reference.

  Furthermore, when changing the width dimension of the girder side wall portion 16a, the area between the straddle wall panel 42b and the protruding corner wall panel 42a remains the installation area of the intermediate wall panel 42c. The trouble of newly setting the arrangement order of the panel 42a, the straddling wall panel 42b, and the intermediate wall panel 42c can be saved.

  Since the width Wb of the straddling wall panel 42b has regularity that the module dimension M × 1/2 is smaller than the integral multiple of the module dimension M, when the straddling wall panel 42b is manufactured, the intermediate wall The design and members for manufacturing the panel 42c are easily diverted. For this reason, the work burden and cost burden at the time of manufacturing the straddle wall panel 42b can be reduced.

  Since the width dimension Wc of the protruding corner wall panel 42a has regularity that the module dimension M × 1/4 is smaller than the integral multiple of the module dimension M, when manufacturing the protruding corner wall panel 42a, The design and members for manufacturing the intermediate wall panel 42c are easily diverted. For this reason, the work burden and cost burden at the time of manufacturing the protruding corner wall panel 42a can be reduced.

  Since the width dimension Wc of the protruding corner wall panel 42a is smaller than the module dimension M, the protruding corner wall panel 42a can be reduced in size. In this case, even if the protruding corner wall panel 42a has a pair of wall panel portions, the burden of work when transporting the protruding corner wall panel 42a from the factory to the building site or when attaching the protruding corner wall panel 42a to the building frame at the building site. Can be reduced.
