Description

  The present invention relates to a column beam framework frame formed by columns and beams.

  Conventionally, for example, in a building formed by building in a garage on the lower floor of a two-story or three-story building in a narrow area in the city center, the opening in the garage forming part on the lower floor is considerably widened. However, there was a problem that the cost was high.

  Therefore, prepare two wooden pillars each with a metal connection plate attached to the upper end, and one beam composed of a wooden beam plate fixed to at least the upper surface of the metal beam body. On the bottom surface of the lower flange part of both ends of the beam body, provide a portion where the wooden beam plate is not fixed, and overlap the both ends of the lower flange part of this beam body on the connection plate attached to the left and right pillars with bolts and nuts Patent Document 1 discloses a gate-type frame in which two pillars and one beam are framed in a gate shape by being fixed.

  This portal frame is made of metal for the main part of the wooden exterior beam, which improves the strength of the wooden exterior while maintaining the wooden appearance, and the connection between the wooden exterior beam and the wooden column is made of metal and metal. It is necessary to increase the span by improving the joint strength by joining with a wide opening width such as building a garage on the lower floor of a two-story or three-story building, for example. It can be used effectively in some cases.

However, when the portal frame 13 is erected in the garage forming portion 30 on the lower floor as shown in FIG. 10, it is necessary to erect a number of the portal frames 13 in the front-rear direction, which increases costs. There was a problem. Further, when a garage is built in and formed in the lower floor of a two-story or three-story building in a narrow area in the city center, a portion 31 in which a room such as an entrance is formed next to the garage forming portion 30 is provided. In such a case, as shown in FIG. 10, among the gate-type frames 13 that are built at a distance in the front-rear direction, the gate-type frame 13 having a longer span is used as the gate-type frame 13 positioned at the forefront. In this respect, it was necessary to increase the number of portal frames 13 to be built in the front-rear direction in order to bear a predetermined strength. In FIG. 10, P indicates a basic module. When a garage is built in and formed on the lower floor of a two-story or three-story building in a narrow area in the center of the city, the width of the garage forming portion 30 is usually set. Is 3P (three times longer than the basic module, for example, 3m if the basic module is 1m), and the width of the part 31 where the room like the entrance is formed is 2P (twice as long as the basic module, for example, the basic module Is 2 m).

  The present invention has been invented in view of the above-mentioned conventional problems, and even when a room such as an entrance is formed next to a garage forming portion, a long span length corresponding to the garage portion is formed. It is an object of the present invention to form a column beam framework frame having a shape in which a strong E-shape is turned sideways while securing a portion and a portion where a room such as an entrance is formed.

  In order to solve the above problems, a column beam frame according to the present invention is a column beam frame 3 framed by columns 1 and 2, and is made of a wooden beam plate 6 on the upper and lower surfaces of a metal beam body 5. Are attached to the upper end portions of the left and right wooden pillars 1 and the intermediate wooden pillar 1 respectively, and the upper ends of the intermediate pillars 1 are fixed to the upper ends of the intermediate pillars 1. Beams 2 are disposed between both side surface portions of the column head hardware 4 fixed to the top and the side surfaces of the column head hardware 4 fixed to the upper ends of the left and right columns 1, and both end portions of each beam 2 in the longitudinal direction. Is fixed to the side surface portion of the opposite pillar head hardware 4 by a fixing tool and is framed in an E shape.

  By adopting such a configuration, the beam main body 5 which is the main part of the wooden appearance beam 2 is made of metal, so that the strength is improved while being a wooden appearance, and the wooden appearance beam 2 and the wooden column 1 are also provided. By improving the joint strength by joining the metal to the metal, it is possible to configure the column beam frame 3 framed in a strong E shape. Therefore, for example, a garage forming portion 30 that needs to have a wide opening width that is configured by building in a garage on the lower floor of a two-story or three-story building, and a room such as an entrance is formed adjacent to this. If there is a portion 31 to be formed, the column beam frame 3 of the present invention which is framed in an E shape so that the intermediate column 1 is positioned between them is built in the garage forming portion. It is possible to reduce the number of built-in conventional gate-type frames 13 standing in front and rear.

  Also, the left and right ends of the column head hardware 4 fixed to the upper end of the intermediate column 1 and the column head hardware 4 fixed to the upper ends of the left and right columns 1 facing the left and right ends of the intermediate column head hardware 4. A metal joining plate 9 is integrally provided at each side end of the metal beam, and a metal end plate 8 is integrally provided at both ends in the longitudinal direction of the metal beam 2 main body. It is preferable that the plate 8 is abutted and fixed by a bolt 11 and a nut 12.

  Since the opposing joining plate 9 and the end plate 8 are brought into contact with each other and fixed by the bolts 11 and nuts 12, the connection between the wooden appearance beam 2 and the wooden pillar 1 can be made more easily by joining the metal to the metal. It can be performed firmly and the shear strength is increased.

  As described above, the present invention can constitute a column beam frame that has a wooden appearance and has a strong E-frame, and has a garage forming portion on the lower floor and a doorway adjacent to the garage forming portion. In a site where there is a part that forms a room, a column beam frame frame that is E-shaped so that an intermediate column is positioned between the two can be built up and down in the garage formation part. The number of built-in conventional portal frames can be reduced, and the cost can be reduced.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 1, the column beam frame 3 of the present invention is configured by framing three columns 1 and two beams 2 in an E shape (a shape in which the E shape is in a horizontal direction).

  A column head hardware 4 is fixed to the upper ends of the three columns 1. Each column 1 is made of wood and has a fitting slit 14 that opens on the top and side surfaces.

  The column head hardware 4 is configured to be fitted downward from the lower surface of the head 15 and a hanging piece 16 is integrally suspended. The metal column head hardware 4 has a hanging piece 16 fitted into the fitting slit 14 at the upper end of the wooden column 1 and the lower surface of the head 15 is placed on substantially the entire upper surface of the column 1. The drooping piece 16 is fixed by a plurality of fixing tools 17 made of pins, and the lower horizontal piece portion of the head 15 and the pillar 1 are fixed by the fixing tool 17 such as an embedded bolt. A metal column head hardware 4 is fixed to the upper end portion.

  Here, the left and right ends of the column head hardware 4 fixed to the upper end of the intermediate column 1 and the column head hardware fixed to the upper ends of the left and right columns 1 opposite to the left and right ends of the intermediate column head hardware 4. The metal joining plates 9 are integrally provided at the four side end portions.

  A lower mounting bracket 18 is fixed to the lower end of the column 1.

  The beam 2 is a metal / wood composite beam formed by fixing wooden beam plates 6 to both upper and lower surfaces of a metal beam body 5 made of H steel. Metal vertical end portions 10 are fixed to both longitudinal ends of the beam body 5.

  The column beam frame 3 of the present invention, which is formed by framing the three columns 1 and the two beams 2 having the above-described configuration in an E shape, is, for example, a two-story or three-story building. In a site where there is a garage forming portion 30 that needs to have a wide opening width that is configured by building in a garage on the lower floor of the building, and a portion 31 in which a room such as an entrance is formed adjacent thereto. It is formed.

  That is, as shown in FIG. 7, an outer end portion of the garage forming portion 30, an outer end portion of the portion 31 where a room such as an adjacent entrance is formed, and a room such as an entrance adjacent to the garage forming portion 30 are formed. The base portions 19a, 19b and 19c are respectively formed at the boundary portions with the portion 31 to be formed. In the present invention, the front end portions of the base portions 19a, 19b and 19c (the entrance side of the garage forming portion is the front side). The left and right columns 1 and the intermediate column 1 are mounted on the upper surface, and the anchor bolts 20 are fixed to the lower mounting bracket 18 to stand upright. Further, the beams 2 are respectively disposed between both side surface portions of the column head hardware 4 fixed to the upper end portion of the intermediate column 1 and side surfaces of the column head hardware 4 fixed to the upper end portions of the left and right columns 1. The end plates 8 provided at both ends in the longitudinal direction of each beam 2 are brought into contact with and joined to the joining plates 9 provided on the side portions of the opposing column head hardware 4 and fixed by bolts 11 and nuts 12. In this way, the column beam frame 3 is formed in an E shape by the three wooden columns 1 and the two beams 2 having a wooden appearance made of two metal / wood composite beams. Here, since the span length of the garage forming portion 30 is longer than the span length of the portion 31 where a room such as an adjacent entrance is formed, the beam 2 located on the garage forming portion 30 side is a room such as an entrance. It is longer than the beam 2 located on the side of the portion 31 where is formed.

  In addition, a column beam framework frame 3 is formed in advance by forming an E-shaped frame with three wooden pillars 1 and two beams 2 having a wooden appearance made of two metal / wood composite beams. The formed column beam frame 3 may be built on the foundation at the site.

  By the way, in the embodiment, the wooden pillar 1 has a rectangular cross section. For example, the rectangular wooden cross section 1 is 105 mm on the short side of the cross section and 250 mm on the long side, and has a larger cross section than a normal wooden column (for example, the cross section is 105 mm × 105 mm) and has high strength. It has become a thing. In this way, in order to increase the strength, the pillar 1 used in the present invention having a rectangular cross section larger than that of a normal wooden pillar is installed on a pillar street L passing through the center of a pillar having a normal small square section. When the side surface of one short side of the wooden pillar 1 having a rectangular cross section is made to coincide with the side face of a normal pillar, the center of the wooden pillar 1 having a rectangular cross section is biased to one short side of the rectangle. The pillar street L will come to the position. Therefore, as shown in FIGS. 8A and 8B, the central column 1 has a rectangular cross section of the central column 1 on the other side of the central column 1 where the garage forming portion 30 side or a room such as a front door is formed 31. It will be projected in either direction. Which direction is applied can be freely selected for each site.

  As described above, a wide opening width is provided at the rear end of the portion where the column beam framework frame 3 framed in an E shape with the three columns 1 and the two beams 2 of the present invention is installed at the front end portion, that is, In the garage forming portion 30 having a long span length, the garage forming portion 30 is further formed at the boundary portion between the base 19a at the outer end of the garage forming portion 30 and a portion 31 where a room such as a doorway adjacent to the garage forming portion 30 is formed. 6 and FIG. 6 show a gate-type frame 13 that is framed in a gate shape with two wooden pillars 1 ′ and a single wooden beam 2 ′ made of one metal / wood composite beam on the foundation 19c. 7 is erected. The portal frame 13 is basically fixed with a column head hardware 4 'similar to the above on the upper end portion in the same manner as the wooden column 1 used in the column beam frame 3 framed in an E shape. In addition, two wooden pillars 1 ′ having a lower mounting bracket 18 ′ fixed to the lower end portion, and wooden beam plates 6 ′ are fixed to both upper and lower surfaces of a metal beam body 5 ′ similar to the beam 2 described above. It is constructed by using a single beam 2 'that is a metal / wood composite beam.

  That is, the pillars 1 ′ are respectively built on the foundation 19 a at the outer end of the garage forming portion 30 and the foundation 19 c formed at the boundary portion between the garage forming portion 30 and a portion 31 where a room such as an entrance adjacent to the garage forming portion 30 is formed. The beam 2 ′ is disposed between the side surfaces of the column head hardware 4 ′ fixed to the upper ends of the left and right columns 1 ′, and provided at both ends in the longitudinal direction of the beam 2 ′. The end plates 8 ′ are in contact with and joined to the joining plates 9 ′ provided on the side surfaces of the opposing column head hardware 4 ′, and are fixed by bolts 11 and nuts 12. In this way, the portal frame 13 is formed by the two wooden pillars 1 ′ and the beam 2 ′ having a wooden appearance made of one metal / wood composite beam.

  In the field where the garage forming part 30 with a wide opening width and the part 31 in which a room such as an entrance is formed adjacent to the garage forming part 30 in the two-story or three-story lower part as described above exist. A column beam frame 3 which is formed in an E-shape with three pillars 1 and two beams 2, and a portal frame 13 which is formed by linking two columns 1 and one beam 2 into a gate shape; In combination, the strength, in particular, the shearing force is increased compared to the case where only a large number of portal frames 13 are provided in the front-rear direction in the garage forming portion 30 with a wide opening width. As a result, the portal frame 13 can be reduced. This is advantageous in terms of cost.

  When higher strength is required, a metal beam main body 5 made of H steel constituting the main portion of the beam 2 having a high web height is used as shown in FIG.
