Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a front view showing the configuration of a building 100 according to an embodiment of the present invention. The building 100 is a steel structure building with a steel frame and multiple floors. In the example of FIG. 1, the building 100 is configured to have two layers as a plurality of layers, but it may be configured to have three or more layers.

The building 100 has a reinforced concrete foundation structure (not shown) fixed to the ground, and a frame structure 10 as a frame structure composed of frame members such as column members 30 and beam members 40. It consists of a fixed superstructure; Note that the frame members constituting the frame frame 10 are standardized, and are manufactured in advance at a factory and then transported to a construction site and assembled. As described above, the building 100 according to the present embodiment is preferably applied to an industrialized building, a prefabricated building, a system building, and the like.

The foundation structure is located below the frame frame 10 and supports the frame frame 10. Specifically, the foundation structure is a reinforced concrete cloth foundation with an I-shaped cross section, and includes a footing portion and a rising portion serving as a foundation beam. Moreover, a column base fixing part for fixing the column base of the column member 30 of the frame frame 10 is provided at the upper end of the rising part of the foundation structure, and an anchor bolt protrudes from the upper surface of the rising part.

The upper structure includes a frame frame 10 composed of a plurality of column members 30 and a plurality of beam members 40 installed between the column members 30, and an outer peripheral wall 80 disposed on the outer periphery of the frame frame 10. , and a partition (not shown) that separates the floors into an indoor space on the upper floor and an indoor space on the lower floor.

The outer peripheral wall 80 includes an exterior member, a heat insulating member, and an interior member. The exterior member can be constructed of, for example, a panel of lightweight aerated concrete (hereinafter referred to as "ALC etc.". "ALC" is an abbreviation of "autoclaved light weight concrete"), and The outer layer of the outer peripheral wall 80 can be formed by connecting a plurality of ALC panels around the periphery. The heat insulating member can be formed of a foamed resin material such as phenol foam, polystyrene foam, urethane foam, etc., and is connected along the inner surface of the outer layer formed by the above-mentioned exterior member to form the outer peripheral wall 80. can form a heat insulating layer. Furthermore, for example, a gypsum board can be used as the interior member, and by being connected to the inside of the heat insulating layer, the inner layer of the outer peripheral wall can be formed.

The partition includes a floor support member. The floor support member can be composed of, for example, an ALC panel. The floor support member is installed between the beam members 40 and is directly or indirectly supported by the beam members 40.

Here, the "partition body" is something that partitions the indoor space on the upper floor and the indoor space on the lower floor, and includes the area from the top surface of the indoor space on the lower floor to the floor surface of the indoor space on the upper floor, excluding the frame frame 10. It means an assembly of members located in between. Therefore, in addition to the above-mentioned floor support members, the partition body may include, for example, ceiling interior members that are directly or indirectly fixed to the floor support members and that constitute the ceiling surface of the indoor space on the lower floor, and floor support members. This concept includes floor interior materials such as flooring, which are laminated on top of the members and constitute the floor surface of the indoor space on the upper floor. The partition body of this embodiment partitions an indoor space on the second floor, which is an indoor space on the upper floor, and an indoor space on the first floor, which is an indoor space on the lower floor.

In the frame frame 10 of this embodiment, a plurality of column members 30 are erected on a foundation structure (not shown), and a plurality of beam members 40 are fixed between the column members 30.

As shown in FIG. 1, the column member 30 includes a column main body 31 and a joint box 32 that connects the column bodies 31 to each other. The column main body 31 and the joint box 32 are both made of steel and are square steel pipes with a square cross section and a hollow shape. The joint box 32 is fixed to the longitudinal end of the column main body 31 by welding.

Note that the frame structure 10 shown in FIG. 1 constitutes a two-story building. The column member 30 connects two column bodies 31 with one joint box 32, and has a further joint box 32 provided at the upper end of the upper column body 31. Similarly, in a frame structure constituting a building with N (an integer of 3 or more) layers, N pillar bodies 31 are connected by (N-1) joint boxes 32, and an additional joint box 32 is attached at the upper end. It can be configured by providing. Further, a structure for joining a column member between the joint box on the lower floor and the joint box on the upper floor may be used.

The pillar body 31 can be made of, for example, a 250 mm square square steel pipe, although it varies depending on the design and the hierarchy used. Further, the pillar body 31 may be a square steel pipe with a square diameter of 200 mm, and the square size and thickness can be arbitrarily combined.

FIG. 2 is a diagram showing the configuration of the column-beam fixing part 12 in the frame frame 10 shown in FIG. 1, with (a) being a plan view and (b) being a front view. As shown in FIGS. 2(a) and 2(b), the four beam members 40 touch the column fixing surfaces 42C of the end plate 42 on the beam fixing surfaces 32C formed on the four sides of the joint box 32 of the column member 30. They are fixed in contact.

Note that the column member 30 of this embodiment includes a joint box 32 as a fixing part (hereinafter sometimes referred to as a "beam fixing part") that can fix the beam member 40 to the column main body 31. Although the beam fixing part is welded, the structure of the beam fixing part is not limited to this, and for example, the beam fixing part may be formed by forming a hole in the column member.

Furthermore, the beam member 40 of this embodiment includes a rectangular plate-shaped end plate 42 as a fixing part (hereinafter, sometimes referred to as a "column fixing part") that can fix the column member 30. However, the structure of the column fixing part is not limited to this, and can be designed as appropriate depending on the form of the beam fixing part of the column member. In this embodiment, the beam main body 41 refers to a portion of the beam member 40 excluding the end plate 42 (fixed portion).

When fixing the beam member 40 to the column member 30, the column fixing surface 42C of the end plate 42 is aligned with the beam fixing surface 32C, and a plurality of Insert bolt B into mounting hole 42A. The bolt B reaches the screw hole 32A via the mounting hole 42A. By inserting the bolt B into the screw hole 32A while rotating it, the bolt B is fixed to the screw hole 32A, and the end plate 42 is firmly fixed to the joint box 32.

The column fixing surface 42C can be aligned with the beam fixing surface 32C by, for example, providing positioning holes (not shown) for inserting positioning pins in both the beam fixing surface 32C and the column fixing surface 42C. Alternatively, the outer shapes of the end plate 42 and the joint box 32 may be used to enable alignment of the two.

As shown in FIGS. 2A and 2B, in this embodiment, the end plates 42 of the four beam members 40 are all configured to have the same thickness. Further, for any of the beam members 40, the beam members 40 can be fixed to the column members 30 simply by fastening the bolts B from the mounting surface 42D side of the end plate 42. Thereby, the beam member 40 can be fixed to the column member 30 by an easy and standardized operation.

In FIG. 2B, the beam member 40 fixed to the right side of the column-beam fixing part 12 and the beam member 40 fixed to the left side are configured to have different beam lengths. The beam depth is determined in consideration of the load applied to each member constituting the frame frame 10, and the like. For example, in the case of a high-rise building, a larger load, moment, and shear force are applied to the beam members 40 provided on lower floors, so it is preferable to increase the beam height. Further, since a larger load is applied to the beam member 40 bridging between the column members 30 having a large column interval, it is preferable to increase the beam height. In this embodiment, as will be described later, since the joint box 32 is configured to be able to fix multiple types of beam members 40, the building specifications A plurality of types of beam members 40 can be fixed according to the purpose.

FIG. 3A shows one of the four beam fixing surfaces 32C forming the joint box 32 of the column member 30. A plurality of screw holes 32A for fixing the beam member 40 with bolts B are provided in the beam fixing surface 32C. The screw holes 32A include a screw hole 32A1 (first hole group) for fixing the upper part of the end plate 42 of the beam member 40, and a screw hole 32A2 (second hole group) for fixing the lower part of the end plate 42. have. In FIG. 3(a), the screw holes 32A1 for fixing the top of the end plate 42 are located at five locations at equal intervals in the horizontal direction at the top, and are spaced downward by a distance 2a (meaning twice the distance a) from the top. Two locations are provided horizontally at the location. Further, five screw holes 32A2 for fixing the lower part of the end plate 42 are provided at equal intervals in the horizontal direction at the lowermost part and at a position separated upwardly by a distance a from the lowermost part. Moreover, two locations are provided in the horizontal direction at locations separated upward by a distance 2a and a distance 3a (meaning three times the distance a) from the bottom. In other words, the screw holes 32A1 for fixing the upper part of the end plate 42 are arranged in two places (the screw holes 32A1 at the same height are counted as one place) separated by a distance of 2a in the vertical direction, and The screw holes 32A2 for fixing the lower part are arranged at four locations at intervals of a distance a in the vertical direction (the screw holes 32A2 at the same height are counted as one location). Also, the vertical distance is a distance that is not an integral multiple of distance a. This ensures that the upper mounting hole 42A1 of the end plate 42 corresponds to the screw hole 32A1, and the lower mounting hole 42A2 of the end plate 42 corresponds to the screw hole 32A2 when fixing the beam member 40, which will be described later. It can be fixed accordingly. That is, it is possible to prevent erroneous attachment such as attaching both of the attachment holes 42A1 and 42A2 to the screw hole 32A2 by mistake.

FIG. 3(b) is a diagram showing the configuration of the beam member 40. The beam member 40 has a beam main body 41 and end plates 42 welded to both ends of the beam main body 41 in the longitudinal direction (left-right direction in FIG. 1). In this embodiment, the beam main body 41 is an H-beam steel, and has a web 41A and flanges 41B provided at both ends of the web 41A in the vertical direction. The end plate 42 is formed into a rectangular plate shape, as shown in FIG. 3(b), and has a plurality of mounting holes 42A. As shown in FIGS. 2(a) and 2(b), the end plate 42 is in contact with the beam fixing surface 32C of the joint box 32 and fixed by the bolt B (end plate 42C in FIG. 3(b)). 42) and a mounting surface 42D (the surface of the end plate 42 in FIG. 3(b)) into which the bolt B is inserted and attached to the column member 30. In this embodiment, the outer dimensions of the column fixing surface 42C and the mounting surface 42D of the end plate 42 are configured to be one size smaller than the outer dimensions of the beam fixing surface 32C of the joint box 32.

The reason why the outer dimensions of the column fixing surface 42C and the mounting surface 42D of the end plate 42 are configured to be smaller than the outer dimensions of the beam fixing surface 32C of the joint box 32 is to facilitate ease of construction. It is. However, the present invention is not limited to this embodiment. For example, by aligning the outer dimensions of the beam fixing surface 32C of the joint box 32 and the column fixing surface 42C and mounting surface 42D of the end plate 42, the alignment of both can be performed using the outer shape. It may also be done by Further, in order to use a wider beam, the outer dimensions of the column fixing surface 42C and the mounting surface 42D of the end plate 42 may be configured to be larger than the outer dimensions of the beam fixing surface 32C of the joint box 32. In this way, the outer dimensions of the joint box 32 and the end plate 42 can be changed as appropriate.

The mounting hole 42A is a hole that overlaps with the screw hole 32A of the joint box 32 when the beam member 40 is fixed to the column member 30, and is a hole through which the bolt B is passed when the beam member 40 is connected and fixed with the bolt B. . In this embodiment, a mounting hole 42A1 is provided in the upper part of the end plate 42 at a position corresponding to the screw hole 32A1 on the column member 30 side. That is, right above the upper flange 41B of the beam main body 41, five mounting holes 42A1 are provided at equal intervals in the horizontal direction. Further, two additional mounting holes 42A1 are provided in parallel in the horizontal direction at positions spaced apart downward by a distance 2a from these five mounting holes 42A1. These mounting holes 42A1 are all provided at positions corresponding to the screw holes 32A1 on the column member 30 side.

The seven attachment holes 42A1 shown in FIG. 3(b) are provided offset downward from vertically symmetrical positions with respect to the upper flange 41B. Under the assumption that the vertical distance between the upper and lower mounting holes 42A1 is maintained at the distance 2a as described later, one mounting hole 42A1 (in this case, the mounting hole 42A1 above the upper flange 41B) is connected to the other mounting hole 42A1. This is because higher fixing strength can be obtained by designing the mounting hole 42A1 (in this case, the mounting hole 42A1 below the upper flange 41B) to be as close to the flange 41B as possible. In the example shown in FIG. 3(b), the seven attachment holes 42A1 are provided offset downward by the thickness t of the flange 41B from vertically symmetrical positions with respect to the upper flange 41B. That is, the vertical distance between the center positions of the five mounting holes 42A1 provided above the flange 41B and the top surface of the upper flange 41B is configured to be smaller than the predetermined distance a by the thickness t of the flange 41B. has been done. On the other hand, the vertical distance between the center positions of the two mounting holes 42A1 provided below the flange 41B and the lower surface of the upper flange 41B is configured to be larger than the predetermined distance a by the thickness t of the flange 41B. has been done. However, the offset amount of the attachment hole 42A1 is not limited to the thickness t.

In this embodiment, the predetermined distance a is equal to the interval a between the beam depth values of the plurality of types of beam members 40. That is, the plurality of types of beam members 40 prepared in advance are the plurality of types of beam members whose beam lengths differ by an integral multiple of the distance a, with the distance a as the minimum unit. Note that since the beam width has a tolerance of, for example, about ±4.0 mm, the predetermined distance a may vary due to the influence of the error in the beam width.

A mounting hole 42A2 is provided in the lower part of the end plate 42 at a position corresponding to the screw hole 32A2 on the column member 30 side. That is, immediately below the flange 41B at the lower part of the beam main body 41, five mounting holes 42A2 are provided at equal intervals in the horizontal direction. Furthermore, two additional mounting holes 42A2 are provided in parallel in the horizontal direction at positions spaced apart upwardly by a distance 2a from these five mounting holes 42A2. These attachment holes 42A2 are provided at positions corresponding to the screw holes 32A2 on the column member 30 side.

As described above, screw holes 32A2 are provided on the column member 30 side at intervals of a distance a in the vertical direction, while mounting holes 42A2 are provided on the beam member 40 side at distances of 2a in the vertical direction. There is. This is because a plurality of types of beam members 40 are prepared so that the beam heights are different at intervals of a distance a. That is, screw holes 32A2 are provided on the column member 30 side at intervals of a distance a in the vertical direction as shown in FIG. Even if the beam height of the beam member 40 changes by a multiple of the distance a, by providing the mounting hole 42A2 at can be fixed to the column member 30. That is, multiple types of beam members 40 with different beam heights can be fixed to the same column member 30. In the example of FIG. 3(a), the screw holes 32A2 on the column member 30 side are provided at four locations at distances a in the vertical direction (the screw holes 32A2 at the same height are counted as one location). There is. Therefore, in addition to the combination of the beam member 40 and column member 30 shown in FIGS. 3(a) and 3(b), the screw hole 32A2 offset upward by the distance a is also used for the beam member 40 whose beam height is smaller by the distance a. It can be similarly fixed by using Further, the screw holes 32A2 on the column member 30 side are not limited to the above-mentioned embodiment, and for example, as long as they are provided in at least three places at intervals of 2a in the vertical direction, the screw holes 32A2 on the column member 30 side can also be used for the beam member 40 whose beam width is smaller by the distance 2a. , by using a screw hole 32A2 offset upwardly by a distance 2a. Further, when the screw holes 32A2 are provided in two places at a distance of 2a in the vertical direction, even for the beam member 40 where the beam width is smaller by the distance 2a, one of the screw holes 32A2 (screw hole 32A1 It can be fixed by using the screw hole 32A2) that is closer to .

Next, the relative positions of the outer circumferential wall 80 and the beam member 40 adjacent to the outer circumferential wall 80 will be explained. FIG. 4 is a plan sectional view of a portion of the column-beam fixing portion 12 adjacent to the outer peripheral wall 80 at the right end of FIG. In FIG. 4, an outer peripheral wall 80 is arranged on the outdoor side of the joint box 32. The outer peripheral wall 80 is attached by fastening with bolts or the like to a mounting jig fixed to the flange 41B of the beam member 40. Therefore, by designing the horizontal distance d between the outer end of the flange 41B and the outer peripheral wall 80 to be always equal, the outer peripheral wall 80 can be positioned using a single type of mounting jig. suitable.

In this embodiment, by arranging the screw holes 32A of the column member 30 and the mounting holes 42A of the beam member 40 as described below, the external dimensions (cross-sectional size) of the column member 30 and the size of the beam member 40 can be adjusted. The configuration can be such that the horizontal distance between the outer end of the flange 41B and the outer peripheral wall 80 is always equal, regardless of the width of the flange 41B. More specifically, the distance Δd between the wall-facing surface 32D of the joint box 32 of the column member 30 on the outer peripheral wall 80 side and the outer end of the flange 41B in the direction orthogonal to the outer peripheral wall 80 is always constant. ing.

FIG. 5(a) shows a joint box 32 of a column member 30 with a certain specification. Moreover, FIG. 5(b) shows a state in which the beam member 40 is fixed to the column member 30 shown in FIG. 5(a). Note that the left-right direction in FIGS. 5A and 5B is the left-right direction in FIG. 1, and the left end in the figure is the end facing the outer peripheral wall 80.

In FIG. 5A, the width of the column member 30 is L, and the center position of the screw hole 32A is on the left side of the figure by a distance s from the center line of the column member 30 (when the column member 30 is attached, the center position is on the outer peripheral wall 80). side). FIG. 5(b) shows a beam member 40 having a flange width w attached to a column member 30 having such a screw hole 32A. Here, the distance Δd between the left end of the column member 30 in the figure (that is, the end closest to the outer peripheral wall 80) and the left end of the flange 41B can be expressed by the following equation (1).
Δd=L/2-s-w/2 (1)

Next, FIGS. 6(a) and (b) show an example in which the external dimensions (cross-sectional size) of the column member 30 are changed from the pillar member 30 and beam member 40 shown in FIGS. 5(a) and 5(b). Explain using. In this embodiment, any column member 30 belonging to a column member group consisting of a plurality of types of column members 30 having different external dimensions (cross-sectional sizes) can be used. The width of the column member 30 shown in FIG. 6(a) in the left-right direction increases from L to L+2ΔL compared to that in FIG. 5(a). In this embodiment, in accordance with the increase in the width of the column member 30, the center position of the screw hole 32A in the left-right direction is moved to the left by a distance (s+ΔL) from the center position of the column member 30, as shown in FIG. 6(a). It is set offset to . As a result, the change ΔL in the position of the left end of the column member 30 from the center position in the left-right direction can be canceled by the offset ΔL in the position of the screw hole 32A, so that the left end of the column member 30 and the flange The distance Δd from the left end of 41B is unchanged from the case of FIGS. 5(a) and 5(b), and is maintained at the value of equation (1). In this way, even if the external width of the column member 30 is changed, by horizontally offsetting the screw hole 32A by a distance equal to 1/2 of the change in width, the outer end of the flange 41B and the outer peripheral wall 80 can be easily adjusted. can maintain a constant distance. In other words, changes in the width of the column member 30 can be absorbed by changing the position of the screw holes 32A in the same column member 30, so the mounting configuration of the outer peripheral wall 80 can be unified without affecting the specifications of other members. be able to.

Next, for an example in which the width w of the flange 41B of the beam member 40 is changed with respect to the column member 30 and the beam member 40 in FIGS. 6(a) and (b), FIGS. 7(a) and (b) are used. I will explain. The column member 30 shown in FIG. 7(a) has the same specifications as the column member 30 shown in FIG. 6(a). In the beam member 40 shown in FIG. 7(b), the width of the flange 41B in the left-right direction is increased from w to w+2Δw compared to FIG. 6(b). In this embodiment, in accordance with the increase in the width of the flange 41B, the horizontal position of the beam main body 41 with respect to the horizontal position of the attachment hole 42A is offset by Δw as shown in FIG. 7(b). As a result, the change Δw in the position of the left end of the flange 41B can be canceled by the change Δw in the position of the beam body 41 with respect to the mounting hole 42A, so that the outer end of the column member 30 and the flange 41B The distance Δd from the outer end of the line is unchanged from the case of FIGS. 6(a) and 6(b), and is maintained at the value of equation (1). In this way, even if the width of the flange 41B of the beam member 40 is changed, the outer end of the flange 41B can be maintained by offsetting the beam body 41 with respect to the mounting hole 42A by a distance equal to 1/2 of the width change. The distance between the outer circumferential wall 80 and the outer circumferential wall 80 can be maintained constant. In other words, changes in the width of the flange 41B of the beam member 40 can be absorbed by changing the position of the beam body 41 within the same beam member 40, so the mounting configuration of the outer peripheral wall 80 can be adjusted without affecting the specifications of other members. It can be unified.

In addition, in this embodiment, although the predetermined distance of the screw hole 32A2 and the attachment hole 42A2 in the vertical direction corresponds to the interval a between the beams, the present invention is not limited to this aspect. The predetermined distance between the screw hole 32A2 and the mounting hole 42A2 in the vertical direction may be configured to be an integral multiple (for example, twice) of the distance a.

In this embodiment, the end plates 42 are provided at both longitudinal ends of the beam main body 41, but the present invention is not limited to this embodiment. For example, as shown in FIG. 8, an adapter 43 may be screwed to the longitudinal end of the beam main body 41, and the beam member 40 may be fixed to the column member 30 via this adapter 43. Alternatively, the adapter may be fixed to the column member first. In this case, the adapter 43 constitutes the beam member 40.

In addition, in this embodiment, as shown in FIGS. 3A and 3B, screw holes 32A1 for fixing the upper part of the end plate 42 are provided at two locations at a distance of 2a in the vertical direction (threaded holes at the same height). The hole 32A1 is provided at one location (counted as one hole), while screw holes 32A2 for fixing the lower part of the end plate 42 are provided at four locations at intervals of a in the vertical direction. The upper screw hole 32A1 is used regardless of the beam size of the beam member 40, while two of the four screw holes 32A2 for fixing the lower part of the end plate 42 are selected and used depending on the beam size. It was configured as follows. However, the embodiment is not limited to this embodiment, and for example, screw holes 32A2 for fixing the lower part of the end plate 42 are provided at two locations at a distance of 2a in the vertical direction, while screw holes 32A2 for fixing the upper part of the end plate 42 are provided at two locations at a distance of 2a in the vertical direction. The holes 32A1 may be provided at four locations at intervals of a distance a in the vertical direction. In that case, the lower screw hole 32A2 is used regardless of the beam size of the beam member 40, while two of the four screw holes 32A1 for fixing the upper part of the end plate 42 are selected depending on the beam size. Can be used. Furthermore, the screw holes 32A1 may be provided at three or more locations at intervals of a distance a in the vertical direction, and the threaded holes 32A2 may be provided at three or more locations at intervals of a distance a in the up and down direction.

As described above, in this embodiment, the column member 30 that can fix the end plate 42 of the beam member 40 has a plurality of screw holes 32A1 that can fix the upper part of the end plate 42 of the beam member 40, and a beam A plurality of screw holes 32A2 are provided for fixing the lower part of the end plate 42 of the member 40, and the screw holes 32A2 include four screw holes 32A2 lined up at a predetermined distance a in the longitudinal direction of the column member 30. Configured. This makes it possible to fix beam members 40 of different beam sizes to column members 30 of the same specification. At this time, since the column fixing surface 42C corresponding to the beam deflection on the side of the beam member 40 comes into contact with the column member 30, a bonding strength corresponding to the beam deflection can be ensured. Note that the screw holes 32A2 may be provided at intervals that are an integral multiple (twice or more) of the predetermined distance a. For example, the interval between the screw holes 32A2 adjacent to each other in the longitudinal direction of the column member 30 may be 2a. Further, there may be a mixture of places where the distance between the screw holes 32A2 is a and places where the distance is 2a.

Moreover, in this embodiment, the hole closest to the screw hole 32A2 for fixing the lower part among the screw holes 32A1 for fixing the upper part of the end plate 42, and the hole closest to the screw hole 32A1 among the screw holes 32A2 The distance X in the vertical direction from the hole is configured so as not to be an integral multiple of the predetermined distance a. Thereby, it is possible to prevent erroneous attachment such as attaching both of the attachment holes 42A1 and 42A2 on the beam member 40 side to one screw hole 32A2 by mistake.

Further, in this embodiment, the distance between the mounting holes 42A2 on both sides in the thickness direction of the flange 41B of the beam member 40 is set to 100±3 [mm]. As a result, in response to the fact that beam spacing standards are mainly defined at 50 [mm] pitches, a beam member group consisting of multiple types of beam members 40 with beam spacings prepared at 50 [mm] intervals is created. Any beam member 40 belonging thereto can be easily fixed to the column member 30 of the same type. That is, mounting holes 42A2 are provided at 100 [mm] intervals in the vertical direction on both sides of the flange 41B on the beam member 40 side, and screw holes 32A2 are provided at 50 [mm] intervals in the vertical direction on the column member 30 side. Therefore, when fixing a beam member 40 whose beam width is different from the current one by 50 [mm], the screw holes 32A2 used by the mounting holes 42A2 on both sides of the flange 41B should be set one pitch (50 [mm]) apart from each other. What is necessary is just to change to screw hole 32A2. Furthermore, the reason why the spacing between the mounting holes 42A2 on both sides of the flange 41B is set to 100 [mm] instead of 50 [mm] is because if the spacing is 50 [mm], the distance between the flange 41B and the mounting hole 42A2 will be too close. This is because it becomes difficult to connect the mounting hole 42A2 and the screw hole 32A2 with the bolt B.

Note that ±3 [mm] in the distance 100±3 [mm] between the mounting holes 42A is a value resulting from the fitting tolerance between the mounting holes 42A and the bolts B. That is, the mounting hole 42A into which the bolt B, which is a high-strength bolt, is inserted may be configured to have a diameter that is 3 mm larger than the nominal diameter of the bolt B. Even when the distance between the mounting holes 42A is determined to be 100 [mm] based on 50 [mm], which is the interval between the beam width values of the plurality of types of beam members 40, the distance between the mounting holes 42A is 100±3. This is because screw fastening is possible even if the thickness changes within the range of [mm].

Although the above-mentioned tolerance of the distance between the mounting holes 42A of ±3 [mm] is due to the clearance between the screw hole 32A and the mounting hole 42A, it should be noted that errors due to other factors may naturally occur. I want to be Further, the distance between the screw holes 32A may also have an error at least as large as that of the mounting hole 42A.

In addition, in this embodiment, the distance between the mounting holes 42A2 on both sides in the thickness direction of the flange 41B of the beam member 40 is 2a±3 [mm] (here, a [mm] is the distance between the mounting holes 42A2 on both sides in the thickness direction of the flange 41B of the beam member 40). , where "2a" means twice the interval a). Thereby, even if the beam spacings are prepared at intervals different from 50 [mm], multiple types of beam members 40 can be easily fixed to the same type of column member 30. That is, mounting holes 42A2 are provided on both sides of the flange 41B on the beam member 40 side at intervals of 2a [mm] in the vertical direction, and screw holes 32A2 are provided in the column member 30 side at intervals of a [mm] in the vertical direction. Therefore, when fixing a beam member 40 whose beam depth is different from the current one by a [mm], the screw holes 32A2 used by the mounting holes 42A2 on both sides of the flange 41B are set one pitch (a [mm]) apart from each other. What is necessary is just to change it to the screw hole 32A2.

Moreover, in this embodiment, the distance from the flange 41B to one attachment hole 42A2 is configured to be different from the distance from the flange 41B to the other attachment hole 42A2. That is, by making the distance from the flange 41B to one of the mounting holes 42A2 as close as possible within a range where the bolt B can be fastened, the fixing strength between the beam member 40 and the column member 30 can be further increased.

Furthermore, in this embodiment, an H-shaped steel having a pair of flanges 41B at the upper and lower parts is used for the beam main body 41, and mounting holes 42A1 and 42A2 are formed on both sides in the thickness direction of each flange 41B, and the upper flange The distance between the mounting holes 42A1 provided on both sides of the lower flange 41B in the thickness direction is equal to the distance between the mounting holes 42A2 provided on both sides of the lower flange 41B in the thickness direction. As a result, the following effects can be obtained. That is, by setting the interval between the mounting holes 42A1 on both sides of the flange 41B to 100 [mm] or 2a [mm] not only for the lower mounting hole 42A2 of the end plate 42 but also for the upper mounting hole 42A1, the first effect can be achieved. The beam member 40 can be used without distinguishing between the upper and lower sides. Second, by changing not only the screw hole 32A2 used by the lower mounting hole 42A2 but also the screw hole 32A1 used by the upper mounting hole 42A1 to 100 [mm] or 2a [mm] next to each other, It becomes possible to change the beam height over a wider range.

Furthermore, the beam heights of the plurality of types of beam members 40 to be prepared may be different at intervals of 100 [mm]. This is achieved mainly by configuring the beam member group by adopting the web height of H-beam steel, which is specified in the standard at intervals of 50 [mm], at intervals of 100 [mm]. be done. In this case, the screw holes 32A2 on the column member 30 side may be provided at 100 [mm] intervals, or may be provided at 50 [mm] intervals so that the vertical position of the beam member 40 can be finely adjusted. Good too.

Furthermore, in this embodiment, even if the external dimensions of the column member 30 (the size of the cross section of the column member 30) are changed, the distance between the outer end of the flange 41B of the beam member 40 and the outer peripheral wall 80 remains constant. It was configured as follows. More specifically, even if the external width of the column member 30 is changed, the outer end of the flange 41B and the outer peripheral wall 80 can be easily connected by offsetting the screw hole 32A by 1/2 the distance of the change in width. The distance between them was maintained constant. Thereby, when attaching the outer circumferential wall 80, the outer circumferential wall 80 can be attached using a single type of attachment jig. In other words, a change in the width L of the column member 30 can be absorbed by changing the position of the screw hole 32A in the same column member 30, so the mounting configuration of the outer peripheral wall 80 can be unified without affecting the specifications of other members. be able to.

Further, in the present embodiment, even if the width w of the flange 41B of the beam member 40 is changed, the distance between the outer end of the flange 41B of the beam member 40 and the outer peripheral wall 80 remains constant. More specifically, even if the width w of the flange 41B of the beam member 40 is changed, the flange 41B can be changed by offsetting the beam body 41 with respect to the mounting hole 42A by a distance equal to 1/2 of the width change. The distance between the outer end of the outer peripheral wall 80 and the outer peripheral wall 80 can be maintained constant. Thereby, when attaching the outer circumferential wall 80, the outer circumferential wall 80 can be attached using a single type of attachment jig. In other words, changes in the width w of the flange 41B of the beam member 40 can be absorbed by changing the position of the beam body 41 within the same beam member 40, so the mounting configuration of the outer peripheral wall 80 can be adjusted without affecting the specifications of other members. It can be unified.

Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art will be able to easily make various changes and modifications based on the present disclosure. It should therefore be noted that these variations or modifications are included within the scope of the present invention. For example, functions included in each component can be rearranged so as not to be logically contradictory, and a plurality of components can be combined into one or divided.
