Description

Technical Field

[0001] The present invention relates to a chevron ramen structure, a column part, and an assembling method of the chevron ramen structure.

Background Art

[0002] Wooden buildings can have advantages such as being able to reduce the period and cost of foundation work because the materials are lighter compared to other construction methods (S / RC method). Also, wood as a building material is attracting attention as a carbon-neutral material because it absorbs and stores carbon dioxide during its growth process.

[0003] For example, Patent Document 1 below discloses a wooden building structure in which a chevron-shaped beam and columns are assembled in a portal frame shape. In a ramen structure that ensures the strength of a building with columns and beams, there are fewer restrictions on the arrangement of walls, and it has the advantage of easily securing a large internal space. However, one of the problems when adopting such a ramen structure is the strength of the column part. To increase the strength of the column part, measures such as thickening the columns that make up the column part are possible, but this will lead to an increase in weight and construction cost.

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a wooden building equipped with a gable ramen structure according to an embodiment of the present invention. The building 1 shown in the figure is a one-story wooden building whose appearance is constituted by a roof 3, an outer wall 4, a door 5, a foundation 6, etc., and a wide space is secured inside. Such a building 1 is particularly suitable for use in, for example, stores, offices, factories, warehouses, etc. In each of the drawings, for the purpose of specifying directions, XYZ axes orthogonal to each other may be shown. In this specification, for convenience, the positive direction of the X axis is referred to as the right direction, the negative direction of the X axis as the left direction, the positive direction of the Y axis as the front direction, the negative direction of the Y axis as the rear direction, the positive direction of the Z axis as the upward direction, and the negative direction of the Z axis as the downward direction.

[0023] FIG. 2 is a view showing the frame portion of the building 1. As shown in the figure, the building 1 of the present embodiment has a gable ramen structure including a rafter portion 7 configured in a gable shape by a pair of web beams 19, 19, and a pair of column portions 8, 8 that support the left and right ends of the rafter portion 7, respectively. In the present embodiment, solid wood materials or assembled materials are used as the materials for the beams and columns constituting the rafter portion 7 and the column portion 8. Further, instead of solid wood materials or assembled materials, a composite material of a wooden material and a resin material can also be used.

[0024] Hereinafter, the gable ramen structure of the present embodiment will be described in detail. FIG. 4 is a perspective view of the web beam 19 used for the rafter portion 7. The web beam 19 includes a shaft member 20. The shaft member 20 is a ladder-shaped member, and includes a first long member 21 and a second long member 22 having a rectangular cross-section extending in the left-right direction (X-axis direction) in the figure, and a plurality of short members 24 having a rectangular cross-section that are installed between these and connect the long members. A plurality of openings 25 separated by the short members 24 are formed along the longitudinal direction between the first long member 21 and the second long member 22. On both side surfaces of the shaft member 20 facing the Y direction (front-rear direction) in FIG. 4, face members 26 are provided so as to cover the openings 25, and the face members 26 are nailed to the first long member 21, the second long member 22, and the short members 24 along the peripheral edges of the openings 25. Using such a web beam 19 is effective for enhancing the rigidity of the rafter portion 7 that supports the roof 3.

[0025] As shown in FIGS. 2 and 3, the pair of web beams 19, 19 used for the purlin portion 7 are symmetrically shaped. One end of each web beam 19 is supported by the column portion 8, and the other end of the web beam 19 abuts against the other end of the other web beam 19 at the center of the building to form the purlin portion 7 in a gable shape. At this time, the two long members extending in the left-right direction in the drawing of each web beam 19 are the first long member 21 on the lower side and the second long member 22 on the upper side.

[0026] FIG. 5 is a view showing the top of the purlin portion 7. As shown in the figure, the other ends of the pair of web beams 19, 19 are joined using screw fasteners 30 and fourth fixtures 35. The screw fastener 30 includes a steel bar 31 having male screw portions 32 formed at both ends, a tightening nut 33 screwed onto the male screw portion 32 of the steel bar 31, and a pressing plate 34 interposed between the tightening nut 33 and the portion to be tightened (here, the second long member 22) to press the portion to be tightened. The upper screw fastener 30 in FIG. 5 is arranged across the pair of second long members 22, 22 in contact, and the second long members 22 facing each other are attracted and fixed by the fastening force of the tightening nuts 33, 33. In the figure, reference numeral 29 is a metal plate-shaped fixture arranged across the second long member 22 and the short member 24. The other (lower-positioned) screw fastener 30 in FIG. 5 is arranged across the pair of short members 24, 24 in contact, and the short members 24 are attracted and fixed by the fastening force of the tightening nuts 33, 33.

[0027] A fourth fixture 35 is disposed below the web beam joint portion shown in FIG. 5. The fourth fixture 35 is a metal plate material and has an inverted V shape in plan view so as to overlap the pair of first long members 21, 21 in contact. A plurality of insertion holes 36 are formed in the fourth fixture 35, and the fourth fixture 35 is fixed across one web beam (first web beam 19A) and the other web beam (second web beam 19B) by screws 37 or the like passing through the insertion holes 36. Although FIG. 5 shows the fourth fixture 35 disposed in the forward direction (positive Y-axis direction) of the purlin portion 7, a similar fourth fixture 35 is also disposed in the rearward direction (negative Y-axis direction) of the purlin portion 7.

[0028] As shown in FIGS. 2 and 3, the column part 8 includes a first column 41 and a second column 46. The first column 41 is a vertically standing wooden column, and is fastened to an anchor bolt 43 embedded in the foundation 6 via a column base metal fitting 42 attached to the lower end of the first column 41 (see FIG. 3). The first column 41 is located closer to the center in the left - right direction (X - axis direction) than the second column 46, and one end of the shaft member 20 of the belly - filled beam 19 abuts against the first surface 41a thereof. The second column 46 is a wooden column arranged to face the second surface 41b of the first column 41, and is fastened to an anchor bolt 48 embedded in the foundation 6 via a column base metal fitting 47 attached to the lower end. The second column 46 is inclined so as to move away from the second surface 41b of the first column 41 as it goes upward, and a reinforcing member for enhancing the strength of the column part 8 can be arranged between the second surface 41b of the first column 41 and the second column 46.

[0029] FIG. 6 is a view showing the joint part of the column part 8 and the belly - filled beam 19 together with its peripheral part. Between the second surface 41b of the first column 41 of the column part 8 and the second column 46, column - to - column reinforcing members 53, 54, 55 having a truss structure constituting a plurality of triangular frameworks are installed. The column - to - column reinforcing members of the truss structure are effective for improving the structural strength of the column part itself. The ends of the column - to - column reinforcing members 53 and 54 are arranged near the contact part of the first column 41 with the first long member 21 to which a large load is applied. Also, the cross - sectional area of the column - to - column reinforcing member 53 arranged between the first reinforcing member 51 and the second reinforcing member 52 described later is larger than the cross - sectional areas of the other column - to - column reinforcing members 54 and 55.

[0030] In the present embodiment, from the viewpoint of effectively suppressing the deformation due to the load applied to the column part 8 via the shaft member 20 of the belly - filled beam 19, the first reinforcing member 51 is arranged on the virtual extension line of the first long member 21 in the shaft member 20, and the second reinforcing member 52 is arranged on the virtual extension line of the second long member 22. These first reinforcing member 51 and second reinforcing member 52 can effectively receive the load input to the first column 41 via the two long members 21 and 22.

[0031] At the position where the ends of the reinforcing members 51, 53, and 54 of the first column 41 converge, a first fixture 60 is provided. This is to avoid the problem of indentation caused by the direct contact of each of the reinforcing members 51, 53, and 54 with the first column 41 under high pressure. As shown in FIG. 7, the first fixture 60 includes a substrate portion 61 fixed to the second surface 41b of the first column 41, a reinforcing member receiving portion 68 erected from the substrate portion 61, and a reinforcing member fixing portion 64. The substrate portion 61, the reinforcing member fixing portion 64, and the reinforcing member receiving portion 68 are all made of metal plates. The substrate portion 61 extends long along the second surface 41b of the first column 41, and the reinforcing member receiving portion 68 and the reinforcing member fixing portion 64 are erected in the upper region thereof. A plurality of insertion holes 62 for fixing screws are provided below the region where the reinforcing member receiving portion 68 and the reinforcing member fixing portion 64 are erected.

[0032] The reinforcing member receiving portion 68 is a plate-shaped member having the same width as the substrate portion 61. Its proximal end is fixed to the substrate portion 61, and the portion on the center line P (see FIG. 7(B)) from the proximal end to the distal end is fixed to the reinforcing member fixing portion 64. The reinforcing member receiving portion 68 is a member disposed on the upper surface of the first reinforcing member 51. As shown in FIG. 7(A), it stands upright in a slightly inclined state along the first reinforcing member 51, and the lower surface of the inter-column reinforcing member 53 is supported by this reinforcing member receiving portion 68.

[0033] The reinforcing member fixing portion 64 is plate-shaped and is erected along the longitudinal center line G (see FIG. 7(B)) of the substrate portion 61 in the upper region of the substrate portion 61. The reinforcing member fixing portion 64 is for fixing the ends of the three reinforcing members 51, 53, and 54, and insertion holes 65, 66, and 67 corresponding to the ends of the reinforcing members 51, 53, and 54 are formed. In addition, slits (not shown) into which the reinforcing member fixing portion 64 is inserted are formed at the ends of the reinforcing members 51, 53, and 54, and pin holes are formed at positions corresponding to the insertion holes 65, 66, and 67 of the reinforcing member fixing portion 64, respectively. As shown in Fig. 6, fixing pins 70, 71, 72 (see Fig. 6) are driven in from one side of each pin hole in such a manner that they penetrate insertion holes 65, 66, 67 with plate-shaped reinforcing member fixing parts 64 inserted into each end of the reinforcing members 51, 53, 54, thereby preventing the reinforcing members 51, 53, 54 from coming off, and the reinforcing members 51, 53, 54 are firmly fixed to the first column 41 via the first fixture 60.

[0034] In this way, a substrate part 61 is interposed between each of the reinforcing members 51, 53, 54 fixed via the first fixture 60 and the second surface 41b of the first column 41, and it is possible to avoid the problem of indentation caused by the direct contact of each of the reinforcing members 51, 53, 54 with the first column 41.

[0035] On the other hand, as shown in Fig. 6, a third fixture 80 for supporting the lower surface of the full-depth beam 19 is attached to the first surface 41a side of the column part 8. As shown in Fig. 8, the third fixture 80 includes a substrate part 81 fixed to the first surface 41a of the first column 41 and a receiving plate part 83 erected from the substrate part 81. A receiving plate support part 85 is arranged between the lower surface of the receiving plate part 83 and the substrate part 81. The substrate part 81, the receiving plate part 83, and the receiving plate support part 85 are all made of metal plates.

[0036] A plurality of insertion holes 82, 82 are formed in a position of the substrate part 81 below the receiving plate part 83, and the third fixture 80 is fixed to the first surface 41a of the first column 41 by screws or the like passing through the insertion holes 82. The upper end of the substrate part 81 extends above the receiving plate part 83 and is interposed between the end of the first long member 21 supported by the receiving plate part 83 and the first column 41, preventing the end of the first long member 21 from indenting into the first surface 41a of the first column 41. Insertion holes 84 are formed on both sides of the receiving plate part 83 of the third fixture 80 with the receiving plate support part 85 sandwiched therebetween, and the receiving plate part 83 of the third fixture 80 is fixed to the first long member 21 of the full-depth beam 19 by screws or the like passing through the insertion holes 84.

[0037] As shown in Fig. 6, the end of the full-depth beam 19 supported by the third fixture 80 is fixed to the first column 41 by a short member 24 with a screw-type fastener 87. The screw fastener 87 includes a bolt shaft 88, a tightening nut 89 that is screwed onto the male thread portion of the bolt shaft 88, and a pressing plate 90 that is interposed between the tightening nut 89 and the portion to be tightened and presses the portion to be tightened. The screw fastener 87 is arranged across the abutting first column 41 and the short member 24, and the first column 41 and the short member 24 facing each other are attracted and fixed by the fastening force of the tightening nut 89.

[0038] As shown in FIG. 6, the second long member 22 of the web girder 19 is connected to the second reinforcing member 52 via the first column 41 by the second fixture 92. In addition, in this FIG. 6, the facing material 26 that covers the side surface of the web girder 19 is omitted and shown. As shown in FIG. 9, the second fixture 92 includes a long member side fitting 93 fixed to the side surface of the second long member 22 via the facing material 26, a reinforcing member side fitting 94 fixed to the side surface of the second reinforcing member 52, a connecting bolt 97 that connects these, and tightening nuts 98, 98. The long member side fitting 93 and the reinforcing member side fitting 94 are made of metal and each include a substrate portion 95 and a through portion 96 in which a through hole into which the connecting bolt 97 is inserted is formed. In the second fixture 92, the second long member 22 and the second reinforcing member 52 facing each other are attracted and fixed by tightening a pair of tightening nuts 98, 98 that are screwed onto the male thread portion at the tip of the connecting bolt 97.

[0039] The gabled ramen structure configured as described above can be assembled through the following steps, for example. First, the other end of the first web girder 19A and the other end of the second web girder 19B are joined using the screw fastener 30 and the fourth fixture (see FIG. 5) to form the gabled rafter portion 7. On the other hand, the first column 41 and the second column 46 that constitute the column portion 8 are erected on the foundation 6. Between the first column 41 and the second column 46, the column-intermediate reinforcing members 53, 54, 55 are installed, and the first reinforcing member 51 scheduled on the virtual extension line of the first long member 21 in the axial member 20 and the second reinforcing member 52 scheduled on the virtual extension line of the second long member 22 are installed. As shown in FIG. 2, the column portion 8 is provided on both the left and right sides of the gabled rafter portion 7.

[0040] Then, the purlin portion 7 is joined to the column portions 8 provided on both the left and right sides. When joining, as shown in FIG. 6, the short member 24 of the web girder 19 supported by the third fixture 80 is fixed to the first column 41 by a screw fastener 87, and the second long member 22 of the web girder 19 is connected to the second reinforcing member 52 by the second fixture 92. As a result, the first long member 21 of the web girder 19 of the purlin portion 7 and the first reinforcing member 51 of the column portion 8 are arranged on the same virtual line, and the second long member 22 of the web girder 19 of the purlin portion 7 and the second reinforcing member 52 of the column portion 8 are arranged on the same virtual line.

[0041] In the gable ramen structure of the present embodiment configured as described above, by adopting a configuration in which the first reinforcing member 51 and the second reinforcing member 52 are respectively arranged on the virtual extension lines of the first long member 21 and the second long member 22 in the axial member 20 constituting the purlin portion 7, it is possible to increase the strength of the column portion 8 constituting the gable ramen structure while suppressing an increase in the number and size of other reinforcing members.
