Description

  The present invention relates to a connection structure for building components that are connected so as to intersect with each other to form corners or intersections.

  As for the connection of corner portions of components used in buildings, a structure in which a web, an upper flange, and a lower flange are sandwiched between plates and fastened with a fixing tool such as a bolt and a nut is known. For example, a structure in which corner portions of constituent materials made of C-type steel materials are connected has been proposed (for example, Patent Document 1).

  In Patent Document 1, the other C-type steel material is connected to one C-type steel material in a state of being orthogonally crossed, and a contact plate is provided on the inner side of the C-type steel material, and a connection plate is provided on the outer side. The edge of the opening of the C-type steel material is sandwiched and connected by the contact plate and the connecting plate, and there is no need to provide a bolt insertion hole in the C-type steel material, and the connection work is somewhat reduced.

JP-A-8-42002 (paragraph numbers 0043 to 0044, FIGS. 14 to 15)

However, in Patent Document 1, since only one side surface, which is the opening of the C-type steel material, is sandwiched between the contact plate and the connecting plate, strong tightening is required, but sufficient connection strength can be easily obtained. In addition, since it is only sandwiched between two plate materials, the positional relationship between the C-type steel material and the two plate materials may gradually shift due to long-term use. Furthermore, the work of arranging a contact plate inside the opening of the C-type steel material, sandwiching the C-type steel material with the connecting plate and fastening with a bolt or the like is very complicated.
Therefore, in view of the above problems, an object of the present invention is to provide a connection structure at a corner or intersection of a building component that can sufficiently secure connection strength and can be easily operated.

  The present invention has been proposed in view of the above, and in a connection structure in which at least an upper flange or a lower flange and a building component having a rising portion are connected to form a corner or an intersection, the building component is provided. Has a rising portion composed of a first rising portion and a second rising portion that are opposed to each other with at least a gap, and extends from the upper end of the first rising portion and / or the second rising portion, or the first flange It consists of either or both of the lower flange extending from the lower end of the rising part and / or the second rising part, and is arranged so as to intersect the building components, and the connecting member in the gap between the arranged building components It is related with the connection structure of the structural material for construction characterized by inserting and connecting.

As described above, the connection structure for building components according to the present invention is basically connected at the time of connection because the connection member is positioned in the gap between the rising parts of the building components arranged so as to intersect. The corners or the intersections can be easily connected without requiring a complicated operation such as bolting the portion between the plates.
Moreover, since it has an upper flange and / or a lower flange, it is possible to easily place and fix functional materials such as a heat insulating material and a sound insulating material, and inner and outer materials.

In addition, when the reinforcing piece is formed on the connecting member, it becomes difficult to be deformed even when a large load is applied, which contributes to reinforcing the connection strength.
Furthermore, when the reinforcing member is attached so as to straddle the structural components arranged so as to intersect, the connection strength can be reinforced.

  The construction material 4 (hereinafter simply referred to as a construction material) 4 in the present invention is composed of the construction materials 4A to 4C shown in FIGS. 1C, 1G, and 1H, the construction material 4D used in FIG. 8 (g) to (i) may be composed of one member obtained by molding and processing a single metal plate, such as constituent materials 4I to 4K, or separately formed and processed as described later. The members (2, 3) may be integrated by various integrated means such as fastening with bolts, nuts, screws, etc., welding, caulking, etc., and as described above, at least the upper flange 42 or the lower flange 43 and the rising It is the structure provided with the part 41. FIG. In addition, although the code | symbol 4 is not attached on drawing, it uses in the description which refers the component material in this invention generically. The same applies to the connecting member 5 described later.

Referring to the constituent material 4A shown in FIG. 1C, the constituent material 4A has a rising portion 41 composed of a first rising portion 111 and a second rising portion 121 that are opposed to each other with at least a gap. The upper flange 42 extending in the left-right direction from the upper end of the rising portion 111 and / or the second rising portion 121, or the lower flange 43 extending in the left-right direction from the lower end of the first rising portion 111 and / or the second rising portion 121. It is the structure which consists of either or both of these.
This component 4A is made of a single member, and the rising portion 41 is formed by superposing the first rising portion 111 and the second rising portion 121 in an opposing manner with a gap (parallel to the left and right). The upper flange 42 extends from the upper end of the first rising portion 111 to one side in the left-right direction, and the second upper flange 122 extends from the upper end of the second rising portion 121 to one side in the left-right direction. Is formed by polymerization (stacked up and down) so as to cover. The lower flange 43 includes a first lower flange 113 extending from the lower end of the first rising portion 111 to one side in the left-right direction, and a second lower flange 123 extending from the lower end of the second rising portion to the other side in the left-right direction.

Further, the upper flange 42 may be formed only on one side in the left-right direction like the component 4A shown in FIG. 1C or the component 4D used in FIG. It may be formed on both sides in the left-right direction as in the constituent material 4C shown. The same applies to the lower flange 43, which may be formed on both sides in the left-right direction, such as the constituent materials 4A to 4C shown in FIGS. 1C, 1G, and 4H and the constituent material 4D used in FIG. Alternatively, it may be formed only in one of the left and right directions like the constituent materials 4I and 4J shown in FIGS. 8 (g) and 8 (h).
Further, the upper flange 42 may be formed by superposing (stacking up and down) the first upper flange 112 so as to cover the second upper flange 122, or may be formed like the component 4D used in FIG. The first upper flange 112 and the second upper flange 122 may be formed by overlapping each other with a gap therebetween.
Moreover, although what was formed in the upper end of the standing part 41 according to description of drawing was described as the upper flange 42 and what was formed in the lower end of the standing part 41 was demonstrated as the lower flange 43, depending on a construction aspect, the structural material 4 may be used. In this case, the above description does not match the actual positional relationship, but the gap formed in the rising portion 41 is excluded except for a special case described later. The open side is the lower flange 43, and the closed side is the upper flange.

Further, in the connecting member 5 inserted into the gap between the constituent members 4 arranged in the present invention, the plurality of insertion pieces 51, 51 inserted into the gap between the rising portions 41 of the constituent member 4 are three-dimensional (three-dimensional). Alternatively, it is configured to be combined in an L shape, a T shape, a cross shape, or the like in a plane (two-dimensional, one surface), and various shapes are selected according to the arrangement mode of the component 4.
In other words, the arrangement and connection in which a plurality of constituent members 4 intersect each other includes forming a corner as shown in FIGS. 1 to 3 and FIG. 5 and forming an intersection as shown in FIG. 6 and FIG. In both cases, the connection at the corners or intersections may connect the end portions in the longitudinal direction of the constituent members 4 or may connect the end portion and the intermediate portion. In addition, the corners or intersections may intersect at right angles or may intersect at an angle, as long as the corners or intersections are formed with an angle.
The material of the connection member 5 includes various known materials such as various metals and composite materials such as FRP, and is not particularly limited as long as a desired connection strength can be obtained. In addition, fixing of the insertion piece 51 of the connecting member 5 and the rising portion 41 of the component 4 includes fastening with bolts and nuts, screwing, welding, bonding with an adhesive, caulking, etc., but the required strength is Any known method may be used as long as it is obtained.

  In the connecting member 5A used in FIGS. 1A and 1B, insertion pieces 51 and 51, which are rectangular vertical pieces, are three-dimensionally combined into an L shape, and the connecting member 5B shown in FIG. Further, a reinforcing piece 52 which is a triangular horizontal piece extending inward from the lower ends of the insertion pieces 51 and 51 is provided. The connection member 5C shown in FIG. 1 (f) is further provided with a reinforcing piece 53 extending outward from the lower end of the insertion pieces 51, 51. When the reinforcing pieces 52 and 53 are formed on the surfaces substantially perpendicular to the connection members 5B and 5C in this way, deformation of the connection members 5B and 5C can be prevented. In addition, the insertion piece 51 may be previously provided with a through hole for fixing a fixing tool such as a screw or a bolt.

In the connection structure shown in FIGS. 1A and 1B, the constituent members 4A and 4A arranged in the horizontal direction are arranged so as to intersect with each other and connected to the gaps between the arranged constituent members 4A and 4A. The member 5A (inserted pieces 51, 51) is inserted and connected by a fixing tool such as a screw, bolt or nut at a position indicated by + in the drawing to form a planar L-shaped corner. In the illustrated embodiment, the upper flanges 42 and 42 and the lower flanges 43 and 43 of the adjacent component members 4A and 4A are notched obliquely. However, if there is no problem in constructing the structure, a deviation of about the plate thickness is repeated. It is also possible to cut out only one of them.
The operation of inserting the connecting member 5 into the gap between the constituent members 4 and 4 according to the present invention is performed when the connecting member 5 is inserted into the constituent members 4 and 4 placed and when the connecting member 5 is inserted. And the case where the members 4 and 4 are appropriately moved so that the connecting member 5 is positioned in the gap.
That is, also in this connection structure, the connecting member 5A may be inserted by being raised from below with respect to the constituent members 4A and 4A arranged so as to form corners, or the constituent member 4A may be inserted into the connecting member 5A. The connection member 5A may be positioned in the gap by being lowered from above, or may be positioned by sliding from the side (end).

As described above, the connection structure of the constituent members 4 of the present invention is connected by inserting the connection member 5 into the gap of the rising portion 41, so basically, the connection portion is sandwiched between the plates at the time of connection and then bolted. Corners or intersections can be connected without requiring complicated work.
Moreover, since the component 4 thus connected has the upper flange 42 and / or the lower flange 43, functional materials such as a heat insulating material and a sound insulating material, and inner and outer materials can be easily arranged and fixed.

  Further, when the connection members 5B and 5C having the reinforcing pieces 52 and 53 are used instead of the connecting member 5A in the illustrated embodiment, the strength of the connecting members 5B and 5C is improved by the reinforcing pieces 52 and 53, and deformation is prevented. The corners using the same can hardly be deformed when a large load is applied.

In particular, when it is desired to increase the connection strength, the reinforcing member 6 may be disposed so as to straddle the constituent members 4 and 4 as necessary.
2A to 2C are examples in which the constituent members 4A and 4A are connected using the connecting member 5A in the same manner as in FIG. 1, and the presence of the connecting member 5A is omitted (omitted). However, for example, as shown in FIG. 2 (a), the plate-like reinforcing member 6A may be fixed so as to straddle the upper flanges 42, 42 of the components 4A, 4A, or as shown in FIG. 2 (b). An L-shaped reinforcing member 6B may be fixed along the inner surfaces of the rising portions 41, 41 of the constituent members 4A, 4A, or the constituent members 4A, 4A of the constituent members 4A, 4A may be fixed as shown in FIG. The L-shaped piece-shaped reinforcing member 6 </ b> C may be fixed along the outer surface side of the rising portions 41, 41. When both of these reinforcing members 6B and 6C are used, the cross-sectional view shown in FIG.

As shown in FIGS. 3 (a) and 3 (b), the overlapping portion of the adjacent constituent members 4A and 4A may be cut out of one of the overlapping portions of the lower flanges 43 and 43, as shown in FIG. Both of the lower flanges 43 and 43 may be cut obliquely as in the embodiment shown in FIG. Of course, the upper flanges 42 and 42 and the lower flanges 43 and 43 are cut obliquely as in the embodiment shown in FIGS. 1A and 1B and the embodiment shown in FIGS. You may do it.
Further, in the embodiment shown in FIG. 4, the first upper flange 112 and the second upper flange 122 are connected so that the constituent members 4D and 4D formed by overlapping each other through a gap form a corner. As shown in FIGS. 3A to 3C, the upper flanges 42 and 42 are not in contact with each other because there is no overlapping portion.
The connecting member 5D used in this embodiment is a reinforcing piece in which insertion pieces 51 and 51, which are rectangular vertical pieces, are three-dimensionally combined in an L shape, and further extend outward from the upper ends of the insertion pieces 51 and 51. 54 is provided.
As in the above embodiments, the insertion piece 51 of the connection member 5D is inserted into the gap of the rising portion 41 of the component 4D and connected. At that time, the reinforcing piece 54 is inserted into the gap of the upper flange 42. Therefore, the strength of the upper flanges 42 and 42 at the corners is also strengthened, and deformation can be prevented.

In the embodiment shown in FIG. 5 (a), as in the examples of FIGS. 1 to 4, the components 4A and 4A arranged in the horizontal direction are arranged so as to intersect with each other to form the corners in the horizontal direction. Instead, one component 4A ′ arranged in the vertical direction (vertical direction) and the other component 4A arranged in the horizontal direction are arranged so as to intersect with each other to form vertical corners. is there. The constituent material 4A ′ arranged in the vertical direction is arranged so that the open side of the gap, that is, the lower flange 43 is located inside the corner.
The connecting member 5E used in this embodiment has a substantially rectangular piece shape with one corner cut out. According to the above-described notation method, the insertion pieces 51 and 51 are planarly (in one face) L-shaped. Further, it can be expressed that a reinforcing piece 55A, which is a triangular vertical piece extending inward from the side ends of the insertion pieces 51, 51, is provided.
In the same manner as in the above embodiments, the insertion pieces 51 and 51 of the connecting member 5E are inserted into the gaps between the rising portions 41 and 41 of the constituent members 4A and 4A, and are connected by fixtures such as screws, bolts and nuts. In addition, L-shaped reinforcing members 6D and 6D are fixed to the front and rear of the reinforcing piece 55 of the connecting member 5E so as to follow the lower surfaces of the orthogonal lower flanges 43 and 43 so as to improve the connection strength at the corners. .
A connecting member 5F shown in FIG. 5B has substantially the same configuration as the reinforcing member 5E except that the shape of the reinforcing piece 55B is different, and has a through hole 511 for fixing a fixing tool such as a screw or a bolt in advance. Drilled. In this way, the reinforcing piece is formed in a triangular shape (straight shape) or a round shape on the same plane at the corner portion of the connecting member 5 such as an L shape or a T shape (see FIG. 6B described later). Thus, the deformation of the connecting member 5 may be prevented.

The embodiment shown in FIG. 6 (a) is similar to the example of FIG. 5 (a) in that one component 4A ′ arranged in the vertical direction (vertical direction) and the other component arranged in the horizontal direction. 4A is arranged so as to intersect, but the end portions are not connected to form a corner portion, but the end portion and the intermediate portion are connected to form a vertical intersection portion.
The connecting member 5G used in this embodiment is in the shape of a rectangular piece, and according to the notation method described above, the insertion pieces 51 and 51 are combined so as to be continuous in a plane (in one plane). it can.
As in the above embodiments, the insertion pieces 51 and 51 of the connecting member 5G are inserted into the gaps between the rising portions 41 and 41 of the constituent members 4A and 4A, and are connected by fixing tools such as screws, bolts and nuts. Further, an L-shaped reinforcing member 6E is provided along the lower surfaces of the lower flanges 43, 43 orthogonal to each other, and an L-shaped reinforcing member 6D is provided so as to follow the upper surfaces of the upper flange 42 and the lower surface of the lower flange 43 which are orthogonal to each other. It was fixed to improve the connection strength at the intersection.
The connection member 5H shown in FIG. 6B is a substantially T-shaped piece, and is the above except that the insertion piece 51 ′ inserted into the gap of the rising portion 41 of the constituent member 4A ′ arranged in the vertical direction is wide. The structure is almost the same as that of the reinforcing member 5G, and a through hole 511 for fixing a fixing tool such as a screw or a bolt is formed in advance. In addition, a reinforcing piece 55C formed in a round shape is provided at the corner portion of the connecting member 5G to prevent deformation of the connecting member 5G.

In the embodiment shown in FIG. 7A, the components 4A and 4A arranged in the horizontal direction are arranged so as to intersect each other as in the examples of FIGS. Instead of forming a part, the end part and the intermediate part are connected to form a vertical crossing part.
As shown in FIG. 7 (b), the connecting member 5I used in this embodiment is bent at substantially the center of a rectangular piece at a substantially right angle to form an L shape, and slits (= at least the component 4) along the half of the folding line. Of the second rising portion 121) and a half of the horizontal piece portion can be bent (raised) at a substantially right angle. The shape piece 57 is integrated with its lower end. In this case, the vertical piece 56 and the vertical piece 571 of the L-shaped piece 57 serve as insertion pieces. The connection member 5 including the connection member 5I is not limited to being formed by bending a rectangular piece, and may be formed by a mold, for example.
As in the above embodiments, the insertion pieces 56 and 571 of the connection member 5I are inserted into the gaps between the rising portions 41 and 41 of the constituent members 4A and 4A, and are connected by fixing tools such as screws, bolts and nuts. In this case, the thickness of the insertion piece 571 is preliminarily set in the lower flange 43 (second lower flange 123) of the component 4A on the side where the insertion piece 56 is inserted (the reference numeral is added for convenience to be distinguished from the other). A notch having substantially the same width was formed.
In this case, as shown in FIG. 7C, the plate-like (trapezoidal) reinforcing member 6F is fixed so as to straddle the upper flanges 42, 42 of the intersecting constituent members 4A ″, 4A, and the connection strength is reinforced. In addition, description of the connection member 5I was abbreviate | omitted in FIG.7 (c).
Although not shown, when a connection member in which the insertion piece is combined in a three-dimensional (three-dimensional) T shape is used, the same as the second rising portion 121 in addition to the second lower flange portion 123. You only have to make a cut.

FIG. 8 shows another aspect of the constituent material 4 used in the present invention, and the constituent materials 4E to 4H shown in FIGS. 8 (a) to 8 (f) are separately formed and processed separately. The first component member 2 and the second component member 3) are integrated by various integration means such as fastening with bolts, nuts, screws, etc., welding, caulking, and the like.
The component 4E shown in FIG. 8A has the same cross-sectional shape as the component 4A shown in FIG. 1C, but the first component is formed at the tip of the second upper flange 32 of the second component 3. It is integrated with the part 2 by line joining.
In the component 4F shown in FIG. 8B, the first upper flange 22 and the second upper flange 32 are integrated by surface bonding. The surface bonding includes partial bonding by spot welding or the like.
The components 4G shown in FIGS. 8 (c) to 8 (e) have a front end (folded portion) of the second upper flange 32 engaged with a front end of the first upper flange 22, and a screw, bolt / nut, or welding not shown. Etc. are integrated. In this way, the upper flanges 22 and 32 of the first component member 2 and the second component member 3 may only overlap or be locked. In this case, the combination of the separate members 2 and 3 ( Positioning) can be performed easily.
Further, in the gap of the rising portion 41 (= the gap of the portion excluding the corner and the intersection), the reinforcing member 46 is plate-shaped (FIG. 8D), L-shaped (not shown), T-shaped (FIG. An angle material such as 8 (e)) may be provided. The reinforcing member 46 can prevent deformation of the first rising portion 21 and the second rising portion 31 when bolt tightening is performed. Further, the surface reinforcing member 47 may be attached not only to the gap between the rising portions 41 but also to the upper and lower surfaces of the upper flange 42 and the lower flange 43.
The component 4H shown in FIG. 8F has a groove 49 shape added to the middle of the upper flange 42. Thus, by providing the groove part 49, the positioning in the case of integration of the 1st component material part 2 and the 2nd component material part 3 can be performed easily.

Components (4I) to (4K) shown in FIGS. 8 (g) to (i) are formed by processing and processing a single metal plate, and the component 4I shown in FIG. The component 4J shown in FIG. 8 (h) includes only the flange 123, and the lower flange 43 includes only the first lower flange 113. The component 4K illustrated in FIG. 8 (i) does not include the lower flange 43.
The constituent materials 4L to 4N shown in FIGS. 8 (j) to (l) have the same cross-sectional shape as the constituent materials 4I to 4K of FIGS. 8 (g) to (i), and are the second constituent materials. The tip of the second upper flange 32 of the part 3 is integrated with the first component part 2 by line joining. 8 (j), the lower flange 43 is constituted only by the second lower flange 33, and the constituent material 4M shown in FIG. 8 (k) is constituted by the lower flange 43 only by the first lower flange 23. The lower flange 43 does not exist in the component 4N of FIG.
The upper flange 42 is not only formed by superposing the first upper flange (112 or 22) and the second upper flange (122 or 32), but only the first upper flange 22 or only the second upper flange 32. It may be formed.

Further, in the constituent material 4G shown in FIG. 8D described above, it is described that the strength is reinforced by inserting the plate-like reinforcing member 46 into the gap between the rising portions 41 except for the corners and intersections. However, in a mode in which the constituent material 4 is formed by integrating different members (first constituent material portion 2 and second constituent material portion 3) that are separately molded and processed by various integration means, this reinforcement is performed. The member 46 may be used as a gap forming member.
For example, the constituent materials 4O to 4R shown in FIGS. 9A to 9D include a first constituent material portion 2 formed into an L-shaped section or a U-shaped section, and a substantially Z-shaped section or a substantially L-shaped section. By combining the second component part 3 formed in the above with a gap forming member 46, gaps as shown in the lower stage can be formed. In other words, in order to form a gap in the end portion or the intermediate portion used for the above-described connection, the gap forming member 46 may be appropriately arranged in other portions and combined to be integrated into a constituent material. In this case, particularly, the constituent members 4P and 4Q shown in FIGS. 9B and 9C are open at both the upper and lower ends of the gap, so that the operation of inserting the connecting member 5 can be performed from both the upper and lower sides. it can. In addition, in these constituent materials 4P and 4Q, although it is a special case in which the upper and lower ends of the gap are opened, the upper flange 42 is shown in the upper part and the lower flange 43 is shown in the lower part.

  Further, the configuration of each part of the constituent material 4 is not particularly limited to the illustrated embodiment. For example, in the illustrated embodiment, in consideration of the support characteristics and strength characteristics, the rising portion 41 has a vertical shape, and the upper flange 42 and the lower flange 43 have a horizontal shape. It is not limited to these.

Further, the rising portion 41 may be provided with an opening (not shown) along the longitudinal direction, and as a through hole for fixing a fixing tool such as a screw or a bolt when the opening is fixed to the connection member 5. It may be a through hole for passing electrical wiring as a building, other wiring or piping, a bolt hole for integrating the first component part 2 and the second component part 3, or It may be used as a bolt hole for fixing an L-shaped or T-shaped angle member fixed to a beam or the like. In addition, the shape of such an opening may be appropriately determined according to the purpose, such as a circle, a rectangle, or an ellipse. For example, if an opening as a bolt hole is provided elongated in the longitudinal direction, the positioning can be finely adjusted at the time of bolting.
Moreover, especially when the opening part is arranged in a direction intersecting the flow direction with the rising part 41, this opening part becomes a communication path (air layer) such as air. Furthermore, providing the opening contributes to reducing the weight of the component 4.

And the component 4 connected so that the corner part or the cross | intersection part may be formed by this invention can be utilized suitably for a roof structure etc. as a purlin edge part etc., for example.
For example, a heat insulating material such as glass wool or foamed resin is supported on the lower flange 43, and a decorative material (wall material) made of various materials is supported, and a base material made of the heat insulating material is placed on the upper flange 42. When the roof structure is constructed, an air layer is formed between the upper surface level of the wall material and the upper flange 42 level of the constituent material 4 (lower surface level of the roof structure), so that the heat insulation is high. For example, in the case where an exterior structure is constructed on a conventional main roof, heat insulating materials in a range not exceeding the thickness of rafters can be arranged, but in the present invention, adjustment is made within the height range of the building component 4 Therefore, higher heat insulation can be easily obtained.

Further, the connection member 5 and the reinforcing member 6 are not limited to the above-described ones. For example, as in the embodiments shown in FIGS. 10 to 12, not only the connection portions at the corners and intersections but also the connection portions. You may make it arrange | position the big connection member 5 and the reinforcement member 6 in the position away from.
The second connecting member 7A shown in FIG. 10 (a) is arranged at the corner portion of the connecting portion to be connected so that the crossing portion in the lateral direction is formed, and has a large inclination compared to the reinforcing members 6A to 6F. Insertion pieces 72, 72 rise from both ends of the piece 71, and a reinforcing piece 73 rises inside the oblique piece 71.
In the embodiment of FIG. 10B, a reinforcing member 6G (61: oblique side, 62: reinforcing piece) having the same configuration except that the insertion pieces 72, 72 are not formed is attached to the corner portion of FIG. 7C. However, both ends of the hypotenuse 61 are placed and fixed on the lower flanges 43 and 43 at positions away from the intersection. When the second connecting member 7A is arranged instead of the reinforcing member 6G, the insertion pieces 72 and 72 are inserted into the gaps between the rising portions 41 and 41 at positions away from the intersecting portions. In addition, in the same figure, description of the connection member 5I used for the crossing part was abbreviate | omitted similarly to FIG.7 (c).
Thus, both the connecting member 5 and the reinforcing member 6 may be used in combination of two or more, and the connection strength is greatly reinforced by combining with a member disposed at a position away from the corner or intersection. be able to.

In each embodiment shown in FIGS. 11 and 12, the second connecting members 7B and 7C are arranged at the corner portions of the embodiment of FIG. 11 and 12 are shown on a 4/6 scale with respect to the other figures.
The second connecting member 7B used in FIG. 11 is inserted into the gap between the rising portions 41 and 41 of the constituent members 4A and 4A ′ that connect the both ends of the trapezoidal slant piece 74 whose planar shape is a trapezoid. In this configuration, flange-shaped reinforcing pieces 75 and 75 are formed inside the inclined piece 74.
The second connecting member 7C used in FIG. 12 has the rising portions 41 and 41 of the constituent members 4A and 4A ′ that are connected so that both ends of the arch piece 76 having a planar arc shape of ¼ arc are formed at the corners. In this configuration, flange-shaped reinforcing pieces 77 and 77 are formed inside the arch piece 76.
Such second connecting members 7B and 7C are not arranged at the corners which are the connecting portions like the L-shaped reinforcing members 6D and 6D used in the embodiment of FIG. Since the part slightly separated from the part is connected, the reinforcing effect is also great due to the truss effect.
