Summary of the Invention

Problems to be Solved by the Invention

[0004] However, an L-shaped plate is provided with two columns and two gradient beams whose one ends are joined to the upper ends of the columns in a vertically oblique long posture and whose other ends face each other to form a gable shape, and only the columns support the gradient beams and the roof provided on the gradient beams. When used for joining the column and the gradient beam of the gable ramen structure, the L-shaped plate is in a posture of bending at a right angle in the vertical and horizontal directions. In that state, when a vertically downward force is applied to the horizontally extending portion of the L-shaped plate, the L-shaped plate may be deformed or damaged, and reinforcement such as a brace or a cane is required.

[0005] The present invention has been made in view of the above circumstances, and includes two columns, two gradient beams that are long in an oblique direction and one end of which is joined to the upper end of the column and the other ends face each other to form a mountain shape, and an insertion steel plate that joins the column and the gradient beam, and aims to provide a mountain-shaped ramen frame that does not require reinforcement such as braces or crutches, and a building with high design quality of the internal space and high degree of freedom in floor plan.

Means for Solving the Problems

[0006] In order to solve the above problems, the mountain-shaped ramen frame according to the present invention includes two columns, two gradient beams that are long in an oblique direction and one end of which is joined to the upper end of the column and the other ends face each other to form a mountain shape, and an insertion steel plate that joins the column and the gradient beam, and is a mountain-shaped ramen frame comprising: The two columns and the two sloping beams are joined in a column-dominant manner, The insertion steel plate has a column insertion portion inserted into the column and a beam insertion portion inserted into the gradient beam, and the column insertion portion and the beam insertion portion The form the same angle as the angle formed by the column and the gradient beam, and are a single plate-shaped member formed, and the insertion steel plate is inserted into the column and the gradient beam parallel to the frame surface which is the surface formed by the mountain-shaped ramen frame. , in the inserted steel plate, at a position corresponding to the side surface in the column span direction among the corners formed by the column and the sloping beam, a second plate hole penetrating in the thickness direction of the inserted steel plate is provided, and on the side surface in the column span direction of the column, a first corner hole penetrating in the span direction corresponding to the second plate hole is provided, and a first cross-member support bracket to which the end of the first cross-member that is long in the span direction and joined to the corner is fixed is fixed to the side surface in the column span direction of the column using the second plate hole, the first corner hole, and a fixture. It is characterized by the above.

[0007] Furthermore, a plurality of first plate holes penetrating in the thickness direction of the insertion steel plate are provided in the beam insertion portion of the insertion steel plate so as to draw an ellipse whose major axis is in the same direction as the long direction of the gradient beam and parallel to the frame surface, and a plurality of first beam holes penetrating in the girder direction corresponding to the first plate holes are provided in the gradient beam. In a state where the beam insertion portion is inserted into the gradient beam, a fixture is inserted into the overlapping first plate holes and the first beam holes. It is characterized by this.

[0009] Furthermore, the gable-shaped ramen frame further includes a connecting member whose vertical length is the same as the vertical length of the small end surface of the other end of the inclined beam, and whose bottom surface is flush with the lower surfaces of the two inclined beams and recessed upward. On the side surface perpendicular to the frame surface of the connecting member, a beam support fitting to which the other end of the inclined beam is fixed is fixed. On the side surface parallel to the frame surface of the connecting member, a third cross-member support fitting to which the end of the third cross-member that is long in the bay direction and joined to the connecting member is fixed is fixed. The connecting member is joined to the other ends of the two inclined beams, respectively, between the other ends of the two inclined beams.

[0010] Furthermore, the beam insertion portion is formed to have a length that does not interfere with the joining position of the lowermost first cross-member among the first cross-members that are long in the bay direction, which is perpendicular to the frame surface, and joined to the middle of the inclined beam in a state of being inserted into the inclined beam.

[0011] The building according to the present invention has a plurality of gable-shaped ramen frames described in claims 1 to 4 The building is such that the gable-shaped ramen frames are arranged in a row at intervals with their frame surfaces parallel, and a cross-member that is long in the bay direction is installed between each of the gable-shaped ramen frames to form a framework. The building is characterized by including a shear wall that extends perpendicular to the frame surface, and the internal space of the building is opened in the bay direction.

Advantages of the Invention

[0012] According to the gable-shaped ramen frame according to the present invention, when the insertion steel plate is in a state of being inserted into the column and the inclined beam, the column insertion portion extends vertically, and the beam insertion portion extends obliquely at the same gradient as the gradient of the inclined beam. In this state, even when a vertically downward force is applied to the beam insertion portion of the insertion steel plate, a repulsive force in the longitudinal direction of the beam insertion portion is generated in the beam insertion portion, so that reinforcement such as braces and crutches is not required.

[0013] Furthermore, a plurality of fixtures for fixing the sloping beam and the insertion steel plate are inserted so as to draw an ellipse, so that the fixtures spread without waste in the longitudinal direction and the short-side direction of the sloping beam, and the sloping beam and the insertion steel plate are fixed. As a result, the fixing between the sloping beam and the insertion steel plate becomes strong, and the strength of the gable ramen frame in the in-plane direction of the frame surface can be increased.

[0014] Furthermore, even when an insertion steel plate for joining a column and a sloping beam is inserted at the corner of the gable ramen frame to which the first cross member is joined, by attaching the first cross member receiving fitting, the shape of the insertion steel plate and the shape of the slit of the column or the sloping beam can be easily joined to the corner of the gable ramen frame without complicating them.

[0015] Furthermore, by arranging a connecting member between the other ends of the two sloping beams, when joining the second cross member to the gable ramen frame, it is only necessary to fix the end of the second cross member to the second cross member receiving fitting of the connecting member, and the joining means of the second cross member does not become complicated. In addition, since the second cross member becomes shorter, the workability of the joining work of the second cross member is improved. Furthermore, since the vertical length of the connecting member is the same as the vertical length of the small end surface of the other end of the sloping beam, the design is not impaired by the connecting member, and the available internal space does not become narrow. Furthermore, since the bottom surface of the connecting member forms a mountain shape so as to be flush with and continuous with the lower surface of the sloping beam, the design can be improved.

[0016] Furthermore, by forming the length of the beam insertion portion of the insertion steel plate long so as not to interfere with the joining position of the third cross member, the fixture spreads and is inserted into the sloping beam and the insertion steel plate. As a result, the fixing between the sloping beam and the insertion steel plate becomes strong, and the strength of the gable ramen frame in the in-plane direction of the frame surface can be increased.

[0017] According to the building according to the present invention, since the internal space of the building is opened in the girder direction, the degree of freedom in the floor plan is increased, and the design of the internal space can be improved.

Mode for Carrying Out the Invention

[0019] The gable-shaped ramen frame 101 and the building 104 according to the present invention will be described below with reference to the drawings. However, the following is merely an exemplary illustration of one embodiment of the present invention, and the scope of the present invention is not limited to the following embodiment and can be appropriately changed without departing from the spirit of the present invention.

[0020] A gable-shaped ramen frame is a framework of a ramen structure composed of at least two columns and two beams. In this framework, two beams, each with one end fixed to the upper end of each of the two columns, extend obliquely upward from one end to the other end and are connected to each other at their other ends to form a peak. As shown in FIG. 1, in one embodiment of the gable-shaped ramen frame 101, the columns 2 are two pieces of wood erected on each foundation 1, and the gradient beams 3 are two pieces of wood that are long in the diagonal direction and have one end 31 joined to the upper end 21 of each column 2, and their other ends 32 face each other to form a gable shape. The gable-shaped ramen frame 101 is a wooden frame composed of an insertion steel plate 7 that joins the upper end 21 of the column 2 and one end 31 of the gradient beam 3, and a connecting member 4 that is wood disposed between the other ends 32 of the two gradient beams 3. In the following description, the plane formed by the gable-shaped ramen frame 101 is called the frame plane, and the direction perpendicular to the frame plane is called the girder direction.

[0021] First, the column 2 erected on the foundation 1 will be described. As shown in FIG. 2, the lower end 22 of the column 2 is joined to the foundation 1 by a column base fitting 6. As shown in FIG. 2(a), the column base fitting 6 is a steel member, which is plate-shaped, faces the upper surface of the foundation 1 in a horizontally extending posture, and includes a lower portion 61 provided with a plurality of column base second holes which are holes (not shown) penetrating in the vertical direction, an upright portion 62 which rises upward from the upper surface of the lower portion 61, a first bottom portion 63 which is plate-shaped and is supported from below at the upper end of the upright portion 62 in a horizontally extending posture, a column insertion portion 65 which is plate-shaped and rises upward from both ends of the first bottom portion 63 and is provided with a plurality of column base first holes 67 which are holes penetrating in the thickness direction thereof, a second bottom portion 64 which protrudes horizontally from the side surface of the upright portion 62 so that the upper part of the column base second hole opens in the vertical direction, and a plate-shaped stiffener 66 whose edge is welded to the lower surface of the second bottom portion 64, the side surface of the upright portion 62, and the upper surface of the lower portion 61. Then, an anchor bolt 204 is inserted into the column base second hole from above, and the column base fitting 6 is fixed to the foundation 1 by driving the anchor bolt 204 into the foundation 1. At this time, by forming the second bottom portion 64 so that the upper part of the column base second hole opens in the vertical direction, a long anchor bolt 204 can be inserted into the column base second hole from above, and a tool for driving the anchor bolt 204 can be used.

[0022] As shown in Fig. 2(a), the lower end 22 of the column 2 fixed to the column base fitting 6 is provided with two column second slits 24 which are slits opening downward and horizontally into which the two column lower insertion portions 65 of the column base fitting 6 are inserted, and a plurality of column third holes 27 which are holes penetrating in the same direction as the column base first hole 67 at positions corresponding to the column base first hole 67. Then, as shown in Fig. 2(b), the column lower insertion portion 65 of the column base fitting 6 is inserted into the column second slit 24 of the column 2, and the drift pin 201, which is a fixing tool, is inserted into the overlapping column base first hole 67 and the column third hole 27, thereby fixing the column 2 and the column base fitting 6. Therefore, the lower end 22 of the column 2 is fixed to the upper surface of the foundation 1 via the column base fitting 6 and stands upright. Note that the first bottom surface 28, which is the bottom surface between the two column second slits 24 of the column 2, is formed so as to abut against the upper surface of the first bottom portion 63 of the column base fitting 6 when the column lower insertion portion 65 of the column base fitting 6 is inserted into the column second slit 24 of the column 2, and the second bottom surface 29, which is the bottom surface not between the two column second slits 24 of the column 2, is formed so as to abut against the upper surface of the second bottom portion 64 of the column base fitting 6 when the column lower insertion portion 65 of the column base fitting 6 is inserted into the column second slit 24 of the column 2. Therefore, the column base fitting 6 can receive the load received from the column 2 on a wide surface, and the fixing strength between the column base fitting 6 and the column 2 is increased. In Fig. 2(b), only one drift pin 201 is shown exemplarily, but the drift pin 201 is inserted into all the overlapping column base first holes 67 and the column third holes 27.

[0023] Next, the joining of the column 2 and the inclined beam 3 will be described. As shown in Fig. 1, the column 2 and the inclined beam 3 are joined via a single insertion steel plate 7 which is a plate-shaped steel material. The insertion steel plate 7 is composed of a column insertion portion 71 inserted into the column 2 and a beam insertion portion 72 inserted into the inclined beam 3, as shown in Fig. 3. As shown in Fig. 1, the angle 402 formed by the column insertion portion 71 and the beam insertion portion 72 is formed to be the same as the angle 401 formed by the column 2 and the inclined beam 3. Then, as shown in Fig. 3, a plurality of plate first holes 73, which are holes penetrating in the thickness direction of the insertion steel plate 7, are provided in the column insertion portion 71 and the beam insertion portion 72 of the insertion steel plate 7.

[0024] As shown in Fig. 3, at the upper end 21 of the column 2, a column first slit 23, which is a slit parallel to the frame surface and opening upward and horizontally, is provided. Further, when the column insertion portion 71 of the insertion steel plate 7 is inserted into the column first slit 23, a plurality of column first holes 25, which are holes penetrating in the girder direction, are provided at positions corresponding to the plate first holes 73 provided in the column insertion portion 71 of the insertion steel plate 7. Then, as shown in Fig. 4, the column insertion portion 71 of the insertion steel plate 7 is inserted into the column first slit 23 of the column 2, a bolt 202, which is a fixture, is inserted into the plate first hole 73 located at the center of the column insertion portion 71 and the column first hole 25 overlapping the plate first hole 73, and tightened with a nut 203 from the tip side of the bolt 202. By inserting a drift pin 201, which is a fixture, into the other overlapping plate first holes 73 and column first holes 25, the column 2 and the insertion steel plate 7 are fixed. In Fig. 4, only one drift pin 201 is shown exemplarily, but fixtures are inserted into all the overlapping plate first holes 73 and column first holes 25.

[0025] As shown in Fig. 3, at one end 31 of the sloping beam 3, a beam first slit 34, which is a slit parallel to the frame surface and opening in three directions like the column first slit 23 of the column 2, is provided. Further, when the beam insertion portion 72 of the insertion steel plate 7 is inserted into the beam first slit 34, a plurality of beam first holes 36, which are holes penetrating in the girder direction, are provided at positions corresponding to the plate first holes 73 provided in the beam insertion portion 72 of the insertion steel plate 7. Then, as shown in Fig. 4, the beam insertion portion 72 of the insertion steel plate 7 is inserted into the beam first slit 34 of the sloping beam 3. Among the overlapping plate first holes 73 and beam first holes 36, a bolt 202, which is a fixture, is inserted into one set of the plate first holes 73 and beam first holes 36, and tightened with a nut 203 from the tip side of the bolt 202. By inserting a drift pin 201, which is a fixture, into the other overlapping plate first holes 73 and beam first holes 36, the sloping beam 3 and the insertion steel plate 7 are fixed. In Fig. 4, only one drift pin 201 is shown exemplarily, but fixtures are inserted into all the overlapping plate first holes 73 and beam first holes 36.

[0026] As described above, the column 2 and the insertion steel plate 7 are fixed, and the inclined beam 3 and the insertion steel plate 7 are fixed, so that the column 2 and the inclined beam 3 constituting the gable ramen frame 101 are joined via the insertion steel plate 7. When the insertion steel plate 7 is inserted into the column 2 and the inclined beam 3, the column insertion portion 71 extends vertically downward, and the beam insertion portion 72 extends obliquely in the same gradient as the gradient of the inclined beam 3. Even when a vertically downward force is applied to the beam insertion portion 72 of the insertion steel plate 7, a repulsive force in the longitudinal direction of the beam insertion portion 72 is generated in the beam insertion portion 72. Therefore, two columns 2 and two inclined beams 3 that are long in the oblique direction and one end 31 of which is joined to the upper end 21 of the column 2 to form a gable shape and the other ends 32 face each other are provided. In the gable ramen frame 101 that supports the load of the inclined beam 3 and the roof provided on the inclined beam 3 only by the column 2, it is not necessary to reinforce braces, cheek rests, etc. with respect to the frame surface, the number of members can be reduced, the construction performance can be improved, and the internal space can be effectively used. In one embodiment, the column 2 and the inclined beam 3 are joined with the column being stronger, but a joint with the beam being stronger may also be used.

[0027] Furthermore, as shown in FIG. 1, the beam insertion portion 72 of the insertion steel plate 7 is formed long in the longitudinal direction of the sloped beam 3. As shown in FIG. 12, in the gabled ramen frame 101, a plurality of purlins, which are third transverse members 53 that are long in the girder direction, are joined to the side surface in the girder direction of the middle girder of the sloped beam 3 at intervals. Therefore, as shown in FIG. 1, the beam insertion portion 72 of the insertion steel plate 7 inserted into the sloped beam 3 is formed long in the longitudinal direction of the sloped beam 3 within a range that does not interfere with the joining position 404 of the third transverse member 53 of the sloped beam 3 so as not to interfere with the joining of the sloped beam 3 and the third transverse member 53. By increasing the length of the beam insertion portion 72 of the insertion steel plate 7, which is a steel material, in the same direction as the longitudinal direction of the sloped beam 3, the fixture can be inserted into the sloped beam and the insertion steel plate over a wide range. As a result, the fixing between the sloped beam and the insertion steel plate becomes stronger, and the strength of the gabled ramen frame in the in-plane direction of the frame surface can be increased. In addition, the area of the insertion steel plate 7 parallel to the frame surface becomes larger, and the insertion steel plate 7 becomes more rigid in the in-plane direction parallel to the frame surface. Since the insertion steel plate 7 itself acts as a shear wall, the gabled ramen frame 101 in which the column 2 and the sloped beam 3 are joined via the insertion steel plate 7 can withstand the load of the gabled ramen frame 101 itself applied in the in-plane direction of the frame surface, the static load due to snow accumulation, and the dynamic load due to wind, rain, and earthquake.

[0028] Also, as shown in FIG. 3, among the plurality of first plate holes 73 provided in the beam insertion portion 72 of the insertion steel plate 7, there are first plate holes 73 arranged so as to draw an ellipse 303 whose major axis is in the same direction as the longitudinal direction of the inclined beam 3 and parallel to the frame surface, and first plate holes 73 arranged at the center of the ellipse 303. And, as shown in FIG. 4, among the plurality of first plate holes 73 provided in the beam insertion portion 72 of the insertion steel plate 7 and the first beam holes 36 overlapping the first plate holes 73, the bolts 202, which are the above-described fixtures, are inserted into the first plate holes 73 arranged at the center of the ellipse 303 and the first beam holes 36 overlapping the first plate holes 73. Drift pins 201, which are fixtures, are inserted into the plurality of first plate holes 73 arranged so as to draw the ellipse 303 and the first beam holes 36. By inserting the fixtures so as to draw the ellipse 303, the fixtures spread without waste in the longitudinal direction and the short direction of the inclined beam 3, and fix the inclined beam 3 and the insertion steel plate 7. As a result, it is not necessary to provide the first plate holes 73 and the first beam holes 36 more than necessary, the fixing of the inclined beam 3 and the insertion steel plate 7 becomes stronger, and the effect of the insertion steel plate 7 as a load-bearing wall in the mountain-shaped ramen frame 101 becomes higher. If the first plate holes 73 and the first beam holes 36 are provided more than necessary to fix the inclined beam 3 and the insertion steel plate 7, the rigidity of the insertion steel plate 7 becomes low due to the large number of first plate holes 73, and the rigidity of the inclined beam 3 becomes low due to the large number of first beam holes 36, and the mountain-shaped ramen frame 101 may become fragile.

[0029] Further, as shown in FIG. 12, in the framework 103 of the building 104 where the gable ramen frame 101 is used, a purlin, which is a first horizontal member 52 long in the girder direction, is joined to the angle 102 formed by the column 2 and the sloping beam 3 of the gable ramen frame 101. In one embodiment where the column 2 and the sloping beam 3 are joined with the column being dominant, the first horizontal member 52 is joined to the side surface in the girder direction of the upper end 21 of the column 2. At the joining position 403 of the first horizontal member 52 at the upper end 21 of the column 2 shown in FIG. 1, a first horizontal member support 90, which will be described later for fixing the end of the first horizontal member 52, is fixed as shown in FIG. 11. As shown in FIG. 5, the first horizontal member support 90 is a steel component composed of a plate-shaped back portion 91 that abuts against the column 2, and two plate-shaped first horizontal member insertion portions 93 that bend at right angles from both ends of the back portion 91 and extend in the same direction and are inserted into the first horizontal member slit 521 of the first horizontal member 52, which will be described later. A plurality of fixing holes 92, which are holes penetrating in the thickness direction of the back portion 91, are provided vertically in a row on the back portion 91 of the first horizontal member support 90, and a plurality of first horizontal member fixing holes 94, which are holes penetrating in the thickness direction of the first horizontal member insertion portion 93, are provided vertically in a row on the first horizontal member insertion portion 93. Among the first horizontal member fixing holes 94 provided in a row, the first horizontal member fixing hole 94 located at the top is formed in a shape that is open upward.

[0030] As shown in Fig. 3, a plurality of angular first holes 26, which are holes penetrating in the girder direction corresponding to the fixed holes 92 of the first cross-member receiver 90, are provided at the joint position 403 of the first cross-member 52 of the column 2. In the insertion steel plate 7, plate second holes 74, which are holes penetrating in the thickness direction of the insertion steel plate 7 corresponding to the angular first holes 26 of the column 2, are provided. Then, as shown in Fig. 5, with the back surface portion 91 of the first cross-member receiver 90 abutted against the column 2 so that the fixed holes 92, the angular first holes 26, and the plate second holes 74 overlap, bolts 202, which are fixtures, are inserted into the overlapping fixed holes 92, angular first holes 26, and plate second holes 74, and nuts 203 are tightened from the tips of the bolts 202 to fix the first cross-member receiver 90 to the column 2. In Fig. 5, only a set of bolts 202 and nuts 203 is exemplarily shown, but bolts 202 are inserted into all the overlapping fixed holes 92, angular first holes 26, and plate second holes 74 and fixed by nuts 203.

[0031] In the case of the gable ramen frame 101 where the first cross-members 52 are joined to both side surfaces in the girder direction of the column 2, the column 2 is sandwiched between two first cross-member receivers 90 so that the respective fixed holes 92, the angular first holes 26, and the plate second holes 74 overlap, bolts 202, which are fixtures, are inserted into the overlapping fixed holes 92, angular first holes 26, and plate second holes 74, and nuts 203 are tightened from the tips of the bolts 202 to fix the two first cross-member receivers 90 to the column 2. Further, in another embodiment where the first cross-member 52 is joined to the inclined beam 3, holes for fixing the first cross-member receiver 90 are provided in the inclined beam 3 instead of the column 2. As described above, even in a state where the insertion steel plate 7 is inserted into the column 2 and the inclined beam 3, the first cross-member receiver 90 can be fixed to the angle 102 formed by the column 2 and the inclined beam 3 of the gable ramen frame 101, and a complicated structure or members are not required to fix the first cross-member 52, and the first cross-member 52 can be easily joined.

[0032] Next, the apex portion of the mountain-shaped ramen frame 101 will be described. As shown in FIG. 1, a connecting member 4 is disposed between the opposite other ends 32 of the two gradient beams 3. As shown in FIG. 7(a), the connecting member 4 is a square columnar wood, and the vertical length thereof is the same as the vertical length of the small end surface 33 of the other end 32 of the gradient beam 3. A beam receiving fitting 80 is fixed to the first side surface 41 which is a side surface perpendicular to the frame surface of the connecting member 4, and a second cross member receiving fitting 85 described later is fixed to the second side surface 42 which is a side surface parallel to the frame surface.

[0033] As shown in FIG. 6, the beam receiving fitting 80 is a steel member composed of a plate-shaped back portion 81 that abuts against the first side surface 41 of the connecting member 4, and two plate-shaped beam top insertion portions 83 that bend at right angles from both ends of the back portion 81 and extend in the same direction and are inserted into the beam second slit 35 of the gradient beam 3 described later. A plurality of fixed holes 82, which are holes penetrating in the thickness direction of the back portion 81, are provided vertically in a row on the back portion 81, and a plurality of beam top fixing holes 84, which are holes penetrating in the thickness direction of the beam top insertion portion 83, are provided vertically in a row on the beam top insertion portion 83. Among the beam top fixing holes 84 provided in a row, the beam top fixing hole 84 located at the top is formed in a shape open upward.

[0034] As shown in FIG. 6, the second cross member receiving fitting 85 is a steel member composed of a plate-shaped back portion 86 that abuts against the second side surface 42 of the connecting member 4, and two plate-shaped second cross member insertion portions 88 that bend at right angles from both ends of the back portion 86 and extend in the same direction and are inserted into the second cross member slit 511 of the second cross member 51 described later. A plurality of fixed holes 87, which are holes penetrating in the thickness direction of the back portion 86, are provided vertically in a row on the back portion 86, and a plurality of second cross member fixing holes 89, which are holes penetrating in the thickness direction of the second cross member insertion portion 88, are provided vertically in a row on the second cross member insertion portion 88. Among the second cross member fixing holes 89 provided in a row, the second cross member fixing hole 89 located at the top is formed in a shape open upward.

[0035] As shown in FIG. 6, the connecting member 4 is provided with a plurality of connecting first holes 44 that penetrate perpendicularly to the first side surface 41 and correspond to a plurality of fixing holes 82 of the beam receiver 80, and a plurality of connecting second holes 45 that penetrate perpendicularly to the second side surface 42 and correspond to a plurality of fixing holes 87 of the second cross-member receiver 85. Then, the connecting member 4 is sandwiched between two beam receivers 80 so that the fixing holes 82 and the connecting first holes 44 overlap, a bolt (not shown) which is a fixing tool is inserted into the overlapping fixing holes 82 and the connecting first holes 44, and a nut (not shown) is tightened from the tip of the bolt, thereby fixing the two beam receivers 80 to the two opposing first side surfaces 41 of the connecting member 4.

[0036] Furthermore, the back surface portion 86 of the second cross-member receiver 85 is brought into contact with the second side surface 42 of the connecting member 4 so that the fixing holes 87 of the second cross-member receiver 85 and the connecting second holes 45 overlap, a bolt (not shown) which is a fixing tool is inserted into the overlapping fixing holes 87 and the connecting second holes 45, and a nut (not shown) is tightened from the tip of the bolt, thereby fixing the second cross-member receiver 85 to the second side surface 42 of the connecting member 4. When the second cross-members 51 are joined to both side surfaces in the girder direction of the mountain-shaped ramen frame 101, the connecting member 4 is sandwiched between two second cross-member receivers 85 so that the fixing holes 87 and the connecting second holes 45 overlap, a bolt (not shown) which is a fixing tool is inserted into the overlapping fixing holes 87 and the connecting second holes 45, and a nut (not shown) is tightened from the tip of the bolt, thereby fixing the two second cross-member receivers 85 to the two opposing second side surfaces 42 of the connecting member 4.

[0037] As shown in Fig. 7(a), at the other end 32 of the inclined beam 3, a beam second slit 35 which is a slit parallel to the frame surface is provided. Further, when the beam top insertion part 83 of the beam receiving fitting 80 is inserted into the beam second slit 35, a plurality of beam second holes 37 which are holes penetrating in the girder direction are provided at positions corresponding to the beam top fixing holes 84 of the inclined beam 3. Then, as shown in Fig. 7(b), the beam top insertion part 83 of the beam receiving fitting 80 fixed to the connecting member 4 is inserted into the beam second slit 35 of the inclined beam 3, and the inclined beam 3 and the beam receiving fitting 80 are fixed by inserting a drift pin 201, which is a fixing tool, into the overlapping beam second holes 37 and the beam top fixing holes 84. Similarly, by fixing the other inclined beam 3 of the gable ramen frame 101 and the beam receiving fitting 80, the other ends 32 of the two inclined beams 3 are joined to the connecting member 4, and a gable shape is formed by the two inclined beams 3 and the connecting member 4. In Fig. 7(b), only one drift pin 201 is shown exemplarily, but the drift pins 201 are inserted into all the overlapping beam second holes 37 and the beam top fixing holes 84.

[0038] As shown in Fig. 12, in the building 104 where the gable ramen frame 101 is used, a purlin which is a second transverse member 51 long in the girder direction is joined to the apex part of the gable ramen frame 101. If the gable ramen frame 101 is a frame in which the other ends 32 of the two inclined beams 3 are joined without the connecting member 4, since the end part of the second transverse member 51 is joined to the position where the other ends 32 of the inclined beams 3 are joined with the beam overhang, the joining means of the second transverse member 51 and the inclined beam 3 becomes complicated. Further, if the gable ramen frame 101 does not have the connecting member 4 and the other ends 32 of the two inclined beams 3 are joined to the side surfaces of one second transverse member 51 respectively, that is, the second transverse member 51 and the inclined beam 3 are joined with the second transverse member overhang, a long second transverse member 51 is required and the joining work thereof becomes a large-scale work.

[0039] However, in the gable ramen frame 101 provided with the connecting member 4 between the other ends 32 of the two gradient beams 3 as in the present invention, it is only necessary to join the end of the second transverse member 51 to the second transverse member receiving member 85 of the connecting member 4. Therefore, the joining means of the second transverse member 51 does not become complicated, and since the second transverse member 51 becomes shorter, the workability of the joining work of the second transverse member 51 is improved. In particular, in the building 104 composed of a plurality of gable ramen frames 101 standing side by side, adjacent gable ramen frames 101 are erected, and the second transverse member 51 is joined to the connecting member 4 of each gable ramen frame 101. Then, adjacent gable ramen frames 101 are erected, and the second transverse member 51 is joined to the connecting member 4 of the gable ramen frame 101. In this way, it is possible to sequentially erect the gable ramen frames 101 that form the building 104 while ensuring the rigidity in the girder direction by the second transverse member 51, and the work safety and workability are significantly improved.

[0040] Next, a building 104 in which the gable ramen frames 101 stand side by side to form a framework 103 will be described. As shown in FIG. 12, the framework 103 of the building 104 is formed by arranging a plurality of gable ramen frames 101 in a straight line so that their frame surfaces are parallel to each other, and by installing transverse members, which are longitudinally long structural bodies in the girder direction, between the respective gable ramen frames 101. The transverse members in one embodiment are the second transverse member 51 which is a ridge beam, the first transverse member 52 which is an eaves girder, and the third transverse member 53 which is a ceiling beam.

[0041] As shown in FIG. 8(a), at the end of the second cross member 51, there are two second cross member slits 511 into which the second cross member insertion portion 88 of the second cross member receiver 85 is inserted, and when the second cross member insertion portion 88 of the second cross member receiver 85 is inserted into the second cross member slit 511, a plurality of second cross member through holes 512, which are holes penetrating in the same direction as the second cross member fixing hole 89, are provided at positions corresponding to the second cross member fixing hole 89 of the second cross member 51. Then, as shown in FIG. 8(b), the second cross member insertion portion 88 of the second cross member receiver 85 fixed to the connecting member 4 is inserted into the second cross member slit 511 of the second cross member 51, and the drift pin 201, which is a fixing tool, is inserted into the overlapping second cross member through holes 512 and the second cross member fixing hole 89, whereby the end of the second cross member 51 is joined to the mountain-shaped ramen frame 101. In FIG. 8(b), only one drift pin 201 is shown exemplarily, but the fixing tool is inserted into all the overlapping second cross member through holes 512 and the second cross member fixing hole 89.

[0042] As shown in FIG. 9(a), at the end of the first cross member 52, there are two first cross member slits 521 into which the first cross member insertion portion 93 of the first cross member receiver 90 is inserted, and when the first cross member insertion portion 93 of the first cross member receiver 90 is inserted into the first cross member slit 521, a plurality of first cross member through holes 522, which are holes penetrating in the same direction as the first cross member fixing hole 94, are provided at positions corresponding to the first cross member fixing hole 94 of the first cross member 52. Then, as shown in FIG. 9(b), the first cross member insertion portion 93 of the first cross member receiver 90 fixed to the connecting member 4 is inserted into the first cross member slit 521 of the first cross member 52, and the drift pin 201, which is a fixing tool, is inserted into the overlapping first cross member through holes 522 and the first cross member fixing hole 94, whereby the end of the first cross member 52 is joined to the mountain-shaped ramen frame 101. In FIG. 9(b), only one drift pin 201 is shown exemplarily, but the fixing tool is inserted into all the overlapping first cross member through holes 522 and the first cross member fixing hole 94.

[0043] At the third cross-member joint position 404 of the sloping beam 3 shown in Fig. 1, as shown in Fig. 11, a third cross-member receiver 95 is fixed. As shown in Fig. 10(a), the third cross-member receiver 95 is a steel component composed of a plate-shaped back portion 96 that abuts against the sloping beam 3, and two plate-shaped third cross-member insertion portions 98 that bend at right angles from both ends of the back portion 96 and extend in the same direction and are inserted into third cross-member slits 531 of a third cross-member 53 to be described later. A plurality of fixing holes (not shown) that are holes penetrating in the thickness direction of the back portion 96 are provided vertically in a row on the back portion 96, and a plurality of third cross-member fixing holes 99 that are holes penetrating in the thickness direction of the third cross-member insertion portion 98 are provided vertically in a row on the third cross-member insertion portion 98. Among the third cross-member fixing holes 99 provided in a row, the third cross-member fixing hole 99 located at the top is formed in a shape that is open upward. As shown in Fig. 1, a plurality of beam third holes 38 that are holes penetrating in the girder direction corresponding to the fixing holes of the third cross-member receiver 95 are provided at the third cross-member joint position 404 of the sloping beam 3. The third cross-member receiver 95 is abutted against the sloping beam 3 so that the beam third holes 38 and the fixing holes of the third cross-member receiver 95 overlap. Bolts (not shown) as fixing tools are inserted into the overlapping beam third holes 38 and the fixing holes of the third cross-member receiver 95, and nuts (not shown) are tightened from the tips of the bolts to fix the third cross-member receiver 95 to the sloping beam 3.

[0044] As shown in Fig. 10(a), at the end of the third horizontal member 53, there are two third horizontal member slits 531 into which the third horizontal member insertion portion 98 of the third horizontal member receiver 95 is inserted, and when the third horizontal member insertion portion 98 of the third horizontal member receiver 95 is inserted into the third horizontal member slit 531, a plurality of third horizontal member through holes 532, which are holes penetrating in the same direction as the third horizontal member fixing hole 99, are provided at positions corresponding to the third horizontal member insertion portion 98 of the third horizontal member 53. Then, as shown in Fig. 10(b), the third horizontal member insertion portion 98 of the third horizontal member receiver 95 fixed to the connecting member 4 is inserted into the third horizontal member slit 531 of the third horizontal member 53, and the end of the third horizontal member 53 is joined to the gable-shaped ramen frame 101 by inserting a drift pin 201, which is a fixture, into the overlapping third horizontal member through holes 532 and the third horizontal member fixing hole 99. In Fig. 10(b), only one drift pin 201 is shown exemplarily, but the fixture is inserted into all the overlapping third horizontal member through holes 532 and the third horizontal member fixing hole 99.

[0045] Then, as shown in Fig. 13, in the framework 103, a shear wall 105 is provided between the columns 2 of adjacent gable ramen frames 101, a ceiling member 101 and a roof (not shown) are provided on the sloping beams 3, and a large opening window 108 parallel to the frame plane is provided in the gable ramen frame 101 arranged at the outermost end, and a floor 109 is provided, thereby forming a building 104. Since the gable ramen frame 101 itself has strength against static and dynamic loads applied to the frame plane, there is no need to provide a shear wall parallel to the frame plane. By not providing a wall parallel to the frame plane, the internal space of the building 104 can be freely used, and by freely setting the floor plan, the designability can be enhanced. As in one embodiment, the building 104 that does not have any wall parallel to the frame plane in the internal space and whose internal space is open in the bay direction can accommodate a large number of people and can also put large objects into the internal space, so it becomes an optimal building 104 for exhibitions, flea markets, sales events, events, etc. Also, when utilized as a composite facility with a plurality of tenants inside, since there is no restriction on the interval for providing a wall parallel to the frame plane in the internal space, there is no restriction on the floor plan of the tenants, and a plurality of tenants can be provided with various floor plans.

[0046] Also, as shown in Fig. 1, the bottom surface 43 of the connecting member 4 of the gable ramen frame 101 is formed in a mountain shape so as to be flush and continuous with the lower surfaces 39 of the two sloping beams 3 of the gable ramen frame 101. Thereby, as shown in Fig. 13, when the building 104 is formed such that the sloping beams 3 and the connecting member 4 can be seen from the inside of the building 104, the appearance of the connection between the sloping beam 3 and the connecting member 4 is improved and the designability is enhanced. Further, each hole into which the fixtures of the column 2, the sloping beam 3, the second transverse member 51, the first transverse member 52, and the third transverse member 53 are inserted is covered with a wooden plug that fits the hole, thereby hiding each hole and enhancing the designability. Further, each slit of the column 2, the sloping beam 3, the second transverse member 51, the first transverse member 52, and the third transverse member 53 is hidden by fitting a piece of wood having a shape that fits the play of the slit into the play portion of each slit, thereby enhancing the designability.

[0047] In one embodiment, the gable ramen frame 101 is built on a foundation, but it may also be built on the upper floor of a building with a general framework on the lower floor. In this case, the column 2 is erected on the structural frame such as columns and beams constituting the lower floor.
