Description

  The present invention relates to a column / beam structure, and more particularly to a column / beam structure having a function of supporting a finished surface material.

  Conventionally, in order to install finishing materials such as glass plates in a pillar / beam structure that constitutes a wall of a building structure, first, after assembling the pillar materials and beam materials, which are structural materials, In general, a support member (for example, a sash frame having a four-sided frame) is attached to a column member or a beam member, and a finish surface material is fitted and fixed to the support member. As described above, in a conventional building structure, a structural material such as a pillar material or a beam material and a support member such as a sash frame are manufactured and constructed as completely separate members. In such a structure, the structural material does not have a function of supporting the finished surface material, and the support member does not function as an auxiliary structural material that bears a load such as the weight of the building structure.

Japanese Patent Laid-Open No. 9-328841 JP-A-11-336244 JP 2001-193357 A

  If the structural material and the support member are separate members as described above, the number of parts for constructing the building structure increases, so that not only the manufacturing cost increases, but also each member is installed separately. The construction was complicated and the construction cost and construction period increased.

  As a technique related to such a problem, Patent Document 1 discloses that a structural member for a building including a pair of end members and an intermediate member is used in an opening of a building such as a window or a door, and this end member is a sash. A wall structure is described which also serves as a window frame and a supporting member for the wall panel. However, the building structural material disclosed in Patent Document 1 is divided into three members, ie, a pair of end members and intermediate members, and the intermediate member and each end member are connected by caulking. In many cases, the assembly is complicated, and furthermore, there is a problem that each part needs to be molded with high accuracy. In addition, since the building structural material of Patent Document 1 is made of an aluminum alloy, it cannot bear a heavy load.

  Patent Document 2 describes a structural material for building that also serves as a support material for supporting a wall material such as a ceiling material. However, the building structural material of Patent Document 2 is arranged on the ceiling of a house, etc., and is intended to fix a wall material such as a ceiling material and an exterior material of a roof. It was not applied to the beam structure.

  Patent Document 3 describes a vibration control structure in which a viscous material is accommodated in a sash frame member of an exterior sash. However, the sash frame of Patent Document 3 is manufactured as a separate part from the pillar material and the beam material, and cannot bear a heavy load such as the weight of the building structure.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a structure in which a structural material that bears the load of a structure also has a function of supporting a finishing surface material, and has fewer parts. It is to provide a new and improved column / beam structure that can be realized with a number and can be easily constructed.

In this way, a part of the cross section of the column material and / or beam material can be made to function as a support member for the finished surface material, so that the column / beam structure having the support function for the finished surface material can be reduced in the number of parts. Can be realized. Moreover, since the clamping part is also made of steel, the clamping part can be integrally formed with a steel column or beam material, or the clamping part is welded or bolted to the column material or beam material. As a result, it is easy to assemble the column / beam structure.

  Further, the sandwiching portion has a pair of protrusions that are continuously projected in the same cross-sectional shape from one end to the other end in the axial direction on at least one side surface of the column member or the beam member, and between the pair of protrusions.

  Moreover, you may make it the said clamping part pinch | interpose the outer peripheral edge part of a finishing surface material through a sealing material. As a result, the sealing material can seal the gap between the column member or beam member and the sandwiching portion, so that the water tightness and air tightness of the column / beam structure can be ensured. In addition, by holding the finishing surface material through a flexible sealing material, it prevents the hard clamping part from directly contacting the finishing material such as a glass plate and damaging the finishing surface material. it can.

  In addition, the clamping part may be configured so as to leave a gap between the column or beam material and the end surface of the finishing surface material so that the outer peripheral edge of the finishing surface material is clamped from both sides in the vertical direction of the finishing surface. . As a result, the column or beam material has a certain margin (edge clearance) and can hold the finished surface material, so even if the column / beam structure is deformed during an earthquake, the load accompanying the deformation is immediately Therefore, it is possible to prevent the finishing surface material from being damaged.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

(First embodiment)
First, a column / beam structure constituting a wall of a building structure according to the first embodiment of the present invention will be described. FIG. 1 is a perspective view showing a column / beam structure according to the present embodiment.

  As shown in FIG. 1, the column / beam structure according to the present embodiment includes a plurality of steel column members 10 extending in the vertical direction and a plurality of steel beam members 20 extending in the horizontal direction as structural materials. It is a structure assembled by joining in the form of a lattice, which constitutes the basic structure of the wall of the building structure. The “lattice shape” as used in this specification refers to a shape in which the column member 10 and the beam member 20 are combined with a gap in the vertical and horizontal directions. The gap may be any shape such as a square, a rectangle, or a parallelogram. It may be rectangular.

  In this embodiment, as shown in FIG. 1, the ends of the divided beam members 20 are joined to the left and right sides of each column member 10 extending in the vertical direction to construct the lattice-like column / beam structure. Has been. Thereby, since each pillar material 10 can be comprised with one steel material, the rigidity of the pillar material 10 to which the big vertical load resulting from the dead weight etc. of a building structure acts can be improved. However, the present invention is not limited to this example, and the ends of the divided column members 10 may be joined to the upper and lower sides of each beam member 20 extending in the horizontal direction to construct a lattice-like column / beam structure. . Note that the column member 10 and the beam member 20 are joined to each other, for example, by welding or bolt joining.

  In the frame surface surrounded by the column member 10 and the plurality of beam members 20, for example, a plurality of glass plates 30 are disposed as finishing surfaces. Specifically, as described above, a plurality of column members 10 and a plurality of beam members 20 are combined in a lattice shape, thereby obtaining a rectangular space partitioned by the column members 10 and the beam members 20, that is, in a horizontal direction. A plurality of rectangular spaces (hereinafter referred to as “lattice spaces”) in which four sides are surrounded by a pair of adjacent column members 10 and a pair of beam members 20 adjacent to each other in the vertical direction are formed. For example, a rectangular glass plate 30 is fitted into each lattice space as a finish surface material. In the example of FIG. 1, two glass plates 30 having the same rectangular shape are disposed in one lattice space. However, the present invention is not limited to this example, and one or three or more finishes are formed in one lattice space. A face material can also be provided.

  The finished surface material such as the glass plate 30 is a flat plate member for covering the opening of the pillar / beam structure forming the wall of the building structure to be constructed and for forming a finished surface exposed to the outside. It is. Therefore, the finished surface material does not bear a load acting on the column / beam structure, unlike a structural surface material such as a wall panel. The finished surface material may be either an exterior material or an interior material of a building structure, but the glass plate 30 in the example of FIG. 1 functions as both the exterior material and the interior material.

  The finish surface material is not limited to the example of the glass plate 30 described above. For example, a plastic plate such as an acrylic plate, a concrete plate such as an ALC (Autoclaved Light-weight Concrete) plate, a decorative plate such as a marble, and a gypsum board Any face material such as wood board can be used. The finished surface material may be a member in which the outer periphery of a surface material such as a glass plate is surrounded by a frame material such as a sash made of aluminum, for example, in a sash frame as described in Patent Document 3 above. A sash containing a viscous material can also be used. Further, the shape of the finished surface material is not limited to the above rectangular shape, and any shape such as a triangle, a polygon, and a belt shape can be adopted as long as it can be fitted into the lattice space.

  In the column / beam structure according to the present embodiment having the overall configuration as described above, a part of the cross section of the column material 10 and the beam material 20 that are structural materials supports a finished surface material such as the glass plate 30. It is distinctive in that it functions as a (sash frame). Below, with reference to FIG.2 and FIG.3, the structure for the column material 10 and the beam material 20 which are structural materials to have the support function of a finishing surface material is demonstrated in detail. 2 is a partially enlarged perspective view showing a column / beam structure according to the present embodiment, and FIG. 3 is a cross-sectional view taken along the line AA in FIG.

  As shown in FIGS. 2 and 3, the column member 10 and the beam member 20, which are structural members, sandwich the outer peripheral end portion of the glass plate 30 via a sealing member 35. Specifically, the column member 10 sandwiches the left side end portion (left end portion) of the glass plate 30 disposed on the right side thereof, and the right side end portion of the glass plate 30 disposed on the left side thereof. Hold (right end). Further, the beam member 20 holds an end portion (lower end portion) on the lower side of the glass plate 30 disposed on the upper side, and an end portion (upper end portion) on the upper side of the glass plate 30 disposed on the lower side. ). Hereinafter, the structures of the column member 10 and the beam member 20 will be described in detail.

  First, the structure of the column member 10 will be described in detail. As shown in FIGS. 2 and 3, the column member 10 is provided, for example, on a flat plate portion 11 erected with respect to the finished surface of the wall body, and on both ends of the flat plate portion 11 in the vertical direction of the finished surface. A thick portion 12 and a sandwiching portion 14 composed of a pair of protrusions 13 projecting from both side surfaces of the flat plate portion 11. By providing thick portions 12 that are thicker than the flat plate portion 11 at both ends of the flat plate portion 11, the cross-sectional performance of the column material 10 is efficiently increased with a small amount of steel, and the rigidity of the column material 10 is improved. it can. The rigidity of the column member 10 can be increased as the distance between the pair of thick portions 12 in the vertical direction of the finished surface is increased.

  The sandwiching portion 14 is a characteristic component according to the present embodiment, and functions as a support member for the glass plate 30 that is a finished surface material. The holding portion 14 is composed of a pair of protrusions 13 that are formed to protrude toward the finished surface, for example, at the center of both side surfaces of the flat plate portion 11. The pair of protrusions 13 extend along the axial direction (vertical direction) of the column member 10, and are continuously protruded with the same cross-sectional shape from the upper end to the lower end of the column member 10 in the axial direction. That is, since this protrusion 13 is not divided on the way from the upper end portion to the lower end portion of the wall of the building structure, the stress in the axial direction of the column member 10 can be transmitted. As a result, the protrusion 13 is included in the structural cross section of the column member 10, and can handle the axial load (vertical load) of the column member 10.

  By providing the pair of protrusions 13 on the column member 10, a U-shaped groove portion 15 extending in the axial direction of the column member 10 is formed between the pair of protrusions 13. The sandwiching portion 14 is configured such that the outer peripheral end portion (left end portion or right end portion) of the glass plate 30 inserted into the groove portion 15 between the pair of projections 13 with a predetermined engagement allowance P is sealed with the sealing material 35 by the pair of projections 13. Hold it through.

  At this time, the holding portion 14 is configured so that a predetermined gap (edge clearance Q) is generated between the end surface 30a (left end surface or right end surface) of the glass plate 30 and the flat plate portion 11 of the column member 10. The outer peripheral edge part of the glass plate 30 is clamped from both sides in the vertical direction of the finished surface. Thereby, even when the column / beam structure is deformed to some extent due to an earthquake or the like, the flat plate portion 11 of the column member 10 and the glass plate 30 can be prevented from coming into direct contact with each other. it can.

  Further, the distance between the pair of projections 13 forming the holding portion 14 (that is, the width of the groove portion 15) is larger than the thickness of the glass plate 30, and a predetermined gap (surface clearance R) is formed between the projection 13 and the glass plate 30. ) Is adjusted so that the arrangement of the pair of protrusions 13 is adjusted. Thereby, the protrusion 13 of the column member 10 and the glass plate 30 can be prevented from coming into direct contact, and a space for interposing the sealing material 35 between them can be secured.

  The sealing material 35 is a gap filling member for obtaining watertightness / airtightness of the gap between the column member 10 and the glass plate 30. The sealing material 35 is formed of, for example, a synthetic resin such as silicone, polysulfide, or polyurethane, and has a certain degree of flexibility. The sealing material 35 is disposed on both sides of the end portion of the glass plate 30 and is interposed between the pair of protrusions 13 and the end portion of the glass plate 30. By interposing such a sealing material 35, not only water tightness and airtightness of the gap between the column member 10 and the glass plate 30 can be obtained, but also the protrusion 13 of the hard column member 10 is made of a brittle material. It is possible to prevent the glass plate 30 from being damaged due to direct contact with the glass plate 30.

  As described above, the column member 10 according to the present embodiment has the holding portion 14 composed of the pair of protrusions 13 that are part of the structural cross section, and the sealing material 35 is formed by the holding portion 14. The outer peripheral edge of the glass plate 30 can be held from both sides. Then, by providing the sandwiching portions 14 composed of the pair of protrusions 13 on both side surfaces (left side surface and right side surface) of the column member 10, one column member 10 is arranged on two left and right sides thereof. Each of the outer peripheral ends of the glass plate 30 can be pinched.

  Next, the structure of the beam member 20 will be described in detail. As shown in FIG. 2, for example, the beam member 20 is arranged symmetrically on both sides of the flat plate portion 21 erected with respect to the finished surface of the wall body and the vertical direction of the flat surface of the flat plate portion 21. And a groove-shaped sandwiching portion 24 configured by the flat plate portion 21 and the bottom portion 22a of the pair of flange portions 22.

  The flat plate portion 21 connects the central portions of the bottom portions 22a of the pair of flange portions 22 to each other. The bottom portion 22a of the flange portion 22 on the one side and the bottom portion 22a of the flange portion 22 on the other side are both planes parallel to the finish surface direction, and are opposed to each other at a predetermined interval. With such a structure, groove portions 25 having a U-shaped cross section, for example, are formed on both side surfaces (upper surface and lower surface) of the beam member 20 in the finish surface direction. The groove portion 25 has the flat plate portion 21 as a bottom surface and the bottom portions 22a of the pair of flange portions 22 as side walls.

  The sandwiching portion 24 is a characteristic component according to the present embodiment, and functions as a support member for the glass plate 30 that is a finished surface material. The holding portion 24 includes a flat plate portion 21 that forms the groove portion 25 and a bottom portion 22 a of a pair of flange portions 22. The sandwiching portion 24 can sandwich the outer peripheral end portion (upper end portion or lower end portion) of the glass plate 30 between both side walls of the groove portion 25 (that is, the bottom portions 22a of the pair of flange portions 22). Yes.

  The groove portion 25 that constitutes the sandwiching portion 24 extends along the axial direction of the beam member 20 and is continuous with the same cross-sectional shape (U-shape) from the upper end to the lower end of the beam member 20 in the axial direction. It is formed into a depression. As a result, the holding portion 24 including the groove portion 25, that is, the flat plate portion 21 and the bottom portion 22a of the pair of flange portions 22 forming the groove portion 25 are included in the structural section of the beam member 20. It becomes possible to handle the axial load (horizontal load) of the material 20. As shown in FIG. 1, the column member 10 is interposed between the plurality of beam members 20 joined on the same axis in the horizontal direction. Since the column 10 is in close contact with each other, horizontal loads can be transmitted to each other via the column 10.

  The sandwiching portion 24 of the beam member 20 is formed by connecting the outer peripheral end portion of the glass plate 30 inserted into the groove portion 25 with a predetermined engagement margin on both side walls of the groove portion 25 (bottom portions 22a of the pair of flange portions 22). Therefore, it is held via the sealing material 35.

  At this time, like the column member 10, a predetermined gap (the edge clearance Q: see FIG. 3) is generated between the upper end surface or the lower end surface of the glass plate 30 and the flat plate portion 21 of the beam member 20. In addition, the sandwiching portion 24 of the beam member 20 sandwiches the outer peripheral end portion of the glass plate 30 from both sides in the finish surface vertical direction. Accordingly, even when the column / beam structure is deformed to some extent due to an earthquake or the like, the sandwiching portion 24 of the beam member 20 and the glass plate 30 can be prevented from being in direct contact with each other, so that the glass plate 30 is preferably prevented from being damaged. it can.

  Similarly to the column member 10, the width of the groove portion 25 forming the sandwiching portion 24 is larger than the thickness of the glass plate 30, and a predetermined gap (above the above described gap between the bottom portion 22 a of each flange portion 22 and the glass plate 30. The arrangement of the bottom portion 22a of the flange portion 22 is adjusted so that the surface clearance R) occurs. Thereby, the flange part 22 of the beam material 20 and the glass plate 30 can be prevented from contacting directly, and the space for the sealing material 35 to interpose can be ensured. In addition, since the sealing material 35 used for the clamping part 24 of the beam member 20 has substantially the same functional configuration as the sealing material 35 used for the clamping part 14 of the column member 10, detailed description thereof is omitted.

  As described above, the beam member 20 according to the present embodiment has the groove-like holding portion 24 that becomes a part of the structural cross section, and the groove-like holding portion 24 allows the sealing material 35 to be sealed. The outer peripheral edge of the glass plate 30 can be held from both sides. Then, by providing the groove-shaped sandwiching portions 24 on both side surfaces (upper side surface and lower side surface) of the beam member 20, one glass member 20 is disposed on both upper and lower sides thereof. The outer peripheral end of each can be pinched.

  The structure of the column member 10 and the beam member 20 according to the present embodiment has been described above. In the column member 10 and the beam member 20, the holding portions 14 and 24 for holding the glass plate 30 are made of steel and extend in the same cross-sectional shape in the axial direction. In this regard, the conventional sash frame is arranged separately in each lattice space surrounded by the pillar material and the beam material as a separate member from the structural member, and the sash frame is greatly different from the divided structure. .

  In such a column / beam structure having the sandwiching portions 14 and 24, the sandwiching portions 14 and 24 are included in the structural section. Therefore, the column member 10 or the beam member 20 is caused by the weight of the building structure. A large load in the axial direction acting on can be borne by the holding portions 14 and 24 as well. Further, the holding portions 14 and 24 as the structural cross section also have a function as a support member (sash frame) of the glass plate 30. Therefore, it is not necessary to install a member (for example, a conventional aluminum alloy sash frame) supporting the finished surface material such as the glass plate 30 as a separate member in addition to the column member 10 and the beam member 20. 10 and the number of parts constituting the beam member 20 can be reduced, and the assembly work can be facilitated.

  Next, a method for manufacturing the steel column member 10 and the beam member 20 provided with the holding portions 14 and 24 as described above will be described. The column member 10 and the beam member 20 are difficult to manufacture with steel because the cross-sectional shape is more complicated than the general column member and the beam member because the holding portions 14 and 24 are provided. It is. Therefore, in the present embodiment, the column material 10 and the beam material 20 are made of hot stamped steel. This hot stamped steel is a shape steel manufactured by a hot extrusion method, and is formed by, for example, extruding a round billet heated to around 1200 ° C. through a die machined to a desired cross-sectional shape. is there.

  By applying such hot stamped steel to the column member 10 and the beam member 20, the column member 10 and the beam having a complicated sectional shape having both the function of the structural member and the function of the support member of the finished surface member. The material 20 can be manufactured relatively easily. Furthermore, by using hot stamped steel, the column member 10 and the beam member 20 can be integrally formed by one member. That is, the structural cross section of the column member 10 and the beam member 20 and the cross section of the holding portions 14 and 24 as the support member for the finished surface material can be formed integrally.

  Therefore, the number of parts for manufacturing the column material 10 and the beam material 20 can be reduced, and an assembling work of a plurality of parts is not necessary. In addition, as compared with the case where a structural material is manufactured by caulking a plurality of parts as described in Patent Document 1, the forming accuracy of the column material 10 and the beam material 20 can be relaxed. Therefore, manufacture of the said column material 10 and the beam material 20 is facilitated, and manufacturing cost can also be reduced. In addition, the column material 10 and the beam material 20 are not limited to the example of the said hot stamped steel, For example, it can also manufacture by casting etc.

  Next, with reference to FIGS. 4-6, the example of a change of the column material 10 and the beam material 20 is demonstrated. In the following description of the modified example, the column material 10 will be described in detail, but the beam material 20 can also be configured in the same manner as the column material 10.

  First, with reference to FIG. 4, the example of a change of arrangement | positioning of the clamping part 14 of the pillar material 10 is demonstrated. As shown in FIG. 4, for example, a pair of protrusions 13 forming the sandwiching portion 14 of the column member 10 can be disposed at one end portion of the flat plate portion 11 in the vertical direction of the finished surface. Accordingly, the cross-sectional area of both end portions of the column member 10 in the vertical direction of the finished surface can be increased by the sandwiching portion 14 disposed at one end portion of the flat plate portion 11 and the thick portion 12 disposed at the other end portion. , The rigidity of the column 10 can be efficiently increased with a small amount of steel.

  Note that the pair of protrusions 13 forming the sandwiching portion 14 of the column member 10 are not only the central portion (see FIG. 3) or one end portion (see FIG. 4) of the column member 10 in the vertical direction of the finished surface, but also the column member 10 It can be placed at any position within the cross section. In addition, instead of installing one clamping portion 14 on each side of the column member 10 as shown in FIGS. 3 and 4, a plurality of clamping portions 14 may be provided on both sides of the column member 10, respectively. it can. As a result, a plurality of sets of finished surface materials can be held by one column member 10.

  Next, with reference to FIG. 5 and FIG. 6, a description will be given of a modification example in which the pillar member 10 is enlarged by forming a single pillar member 10 by joining a plurality of members.

  The column member 10 in the example shown in FIG. 5 is configured by joining one flat plate member 101 arranged in the center and a total of four clamping members 102 arranged two on each side of the flat plate member 101. The The flat plate member 101 and the clamping member 102 are joined to each other by, for example, bolt joining or welding, and both are included in the structural section of the column member 10.

  The thick part 12 for increasing the rigidity of the column member 10 is formed at the outer end of each holding member 102, and the protrusion 13 for holding the glass plate 30 is formed at the inner end. Has been. A pair of clamping members 102 arranged on each side surface of the flat plate member 101 are arranged so that the protrusions 13 face each other with a predetermined interval. The projections 13 of the pair of clamping members 102 function as the clamping unit 14, and the glass plate 30 can be clamped between the pair of opposed projections 13 via the sealing material 35. The sandwiching member 102 having such a complicated cross-sectional shape is preferably composed of, for example, hot stamped steel, but is not limited to such an example.

  In addition, the column member 10 in the example shown in FIG. 6 is divided into five members in total for the three functions of the flat plate portion 11, the thick portion 12, and the sandwiching portion 14. It is a structure. Specifically, the column member 10 in the example shown in FIG. 6 includes one sandwiching member 103 disposed in the center and two flat plates disposed on both sides of the sandwiching member 103 so as to stand in the vertical direction of the finished surface. The member 104 is configured by joining two thick members 105 having a substantially triangular cross section disposed outside the flat plate member 104. The clamping member 103, the flat plate member 104, and the thick member 105 are joined to each other by, for example, bolt joining or welding, and all the members are included in the structural cross section of the column member 10.

  On both sides of the clamping member 103 in the finish surface direction, the pair of protrusions 13 are formed to protrude at a predetermined interval. The pair of protrusions 13 respectively disposed on both sides of the sandwiching member 103 functions as the sandwiching portion 14, and the glass plate 30 can be sandwiched between the pair of protrusions 13 via the sealing material 35. The sandwiching member 103 having such a protrusion 13 and a complicated cross-sectional shape is preferably made of hot stamped steel, for example, but is not limited to such an example.

  As described above, since the pillar member 10 shown in FIGS. 5 and 6 is configured by joining a plurality of members, the structural section of the pillar member 10 can be enlarged, and thereby the vertical direction can be increased. There is an advantage that it can endure a heavy load. All of the plurality of members may be made of hot stamped steel, or only members having a complicated cross-sectional shape may be made of hot stamped steel. Moreover, the shape and the number of installation of the plurality of members constituting the column member 10 and the beam member 20 are not limited to the examples of FIGS. 5 and 6 described above, and various design changes can be made.

(Second Embodiment)
Next, a column / beam structure according to a second embodiment of the present invention will be described. The column / beam structure according to the second embodiment is different from the column / beam structure according to the first embodiment in that a reinforcing surface material is provided instead of a part of the finished surface material. The other functional configurations are substantially the same as those in the first embodiment, and a detailed description thereof will be omitted.

  FIG. 7 is a perspective view showing a column / beam structure according to the second embodiment. As shown in FIG. 7, a reinforcing steel plate 40, which is an example of a reinforcing surface material, is disposed in place of a part of the glass plate 30 in the frame surface surrounded by the column material 10 and the beam material 20. For example, in the example of FIG. 7, the reinforcing steel plate 40 is fitted in the two lattice spaces on the center side among the four lattice spaces at the uppermost stage and the lowermost stage, instead of the glass plate 30. A reinforcing steel plate 40 is fitted into two lattice spaces on both sides of the four lattice spaces in the third stage instead of the glass plate 30.

  The reinforcing steel plate 40 is, for example, a steel reinforcing plate having a rectangular shape, and reinforces the column / beam structure. When the reinforcing steel plate 40 is fitted in each lattice space surrounded by the two right and left column members 10 and the two upper and lower beam members 20, the upper, lower, left and right end surfaces of the reinforcing steel plate 40, the column members 10 and the beam members. 20 is close in size. That is, when the reinforcing steel plate 40 is fitted in the lattice space, the edge clearance Q between the end surface 30a of the glass plate 30 and the column member 10 or the beam member 20 as shown in FIG. Each of the end faces and the flat plate portions 11 and 21 of the column member 10 or the beam member 20 are in surface contact with almost no gap.

  In this way, in the lattice space in which the reinforcing steel plate 40 is disposed instead of the glass plate 30, the space between the upper and lower beam members 20, between the left and right column members 10, and between the column members 10 and the beam members 20. In between, a load can be transmitted via the reinforcing steel plate 40. For this reason, the reinforcing steel plate 40 functions as an auxiliary structural member, and the rigidity in the finished surface of the column / beam structure can be increased. For example, even when a horizontal load is applied to a column / beam structure during an earthquake, the horizontal load can be received by the reinforcing steel plate 40 and distributed to the other column members 10 and beam members 20. -The beam structure can be suitably reinforced to provide an earthquake resistant / damped structure.

  The column / beam structure to which the reinforcing steel plate 40 according to the present embodiment as shown in FIG. 7 is applied is different from the conventional wall structure. In the conventional wall structure, reinforcing face materials (wall panels such as reinforced steel plates) are arranged continuously in the vertical direction from the upper end to the lower end of the wall, or from the left end to the right end of the wall. It was necessary to arrange them continuously in the horizontal direction. On the other hand, in the column / beam structure according to the present embodiment, as shown in FIG. 7, the reinforcing face materials such as the reinforcing steel plates 40 may be arranged in an oblique direction, and are not necessarily continuous in the vertical direction or the horizontal direction. May not be arranged.

(Third embodiment)
Next, a column / beam structure according to a third embodiment of the present invention will be described. The column / beam structure according to the third embodiment is different from the column / beam structure according to the first embodiment in that a bracing material (brace material) is additionally provided. The other functional configurations are substantially the same as those in the first embodiment, and a detailed description thereof will be omitted.

  FIG. 8 is a perspective view showing a column / beam structure according to the third embodiment. As shown in FIG. 8, in the column / beam structure according to the present embodiment, for example, a steel bracing member 50 is additionally installed in a part of each lattice space surrounded by the column material 10 and the beam material 20. The bracing member 50 is bridged on a diagonal line connecting the joint portions of the column member 10 and the beam member 20 obliquely. In the example of FIG. 8, the bracing members 50 are respectively arranged in eight lattice spaces among the sixteen lattice spaces, and the eight bracing members 50 are arranged so as to form a rectangular appearance as a whole. . By additionally installing the bracing material 50 as described above, it is possible to reinforce the column / beam structure and improve the rigidity, thereby providing an earthquake resistant / damping structure.

  FIG. 9 is a partially enlarged perspective view showing a column / beam structure according to a third embodiment. As shown in FIGS. 8 and 9, in the lattice space in which the bracing material 50 is disposed, the rectangular glass plate 30 that is the finishing surface material is obliquely divided at the place where the bracing material 50 is disposed. The upper and lower right triangular glass plates 30A and 30B are divided. The bracing member 50 includes a sandwiching portion 53 that sandwiches the end portions (slanted sides) of the divided right-angled triangular glass plates 30A and 30B.

  Specifically, as shown in FIG. 9, the bracing member 50 is made of, for example, an H-shaped steel including a web 51 and a pair of flanges 53. The pair of flanges 53 of the bracing material 50 constitute a sandwiching portion 54 that sandwiches the oblique sides of the divided glass plates 30A and 30B. The sandwiching portion 54 of the bracing member 50 can sandwich the oblique sides of the glass plates 30 </ b> A and 30 </ b> B from both sides in the vertical direction of the finished surface via the sealing material 35 by a pair of flanges 53. As described above, the glass plates 30A and 30B can be supported more stably by sandwiching the glass plates 30A and 30B not only by the column member 10 and the beam member 20 but also by the bracing material 50.

  In addition, unlike the above, the bracing material 50 may be disposed so as not to sandwich the finished surface material such as the glass plate 30. For example, the bracing material 50 may be disposed on the near side or the far side in the vertical direction of the finished surface of the glass plate 30 and the bracing material 50 may be disposed at a position where the glass plate 30 may not be divided. In this case, the bracing member 50 has a function of reinforcing the column / beam structure by being bridged obliquely between the joint portions of the column member 10 and the beam member 20 at a position where it does not interfere with the glass plate 30. To have.

(Fourth embodiment)
Next, a column / beam structure according to a fourth embodiment of the present invention will be described. The column / beam structure according to the fourth embodiment is different from the column / beam structure according to the first embodiment only in that a string member is additionally provided. Since other functional configurations are substantially the same as those in the first embodiment, detailed description thereof is omitted.

  FIG. 10 is a perspective view showing a column / beam structure according to the fourth embodiment, FIG. 11 is a partially enlarged perspective view showing a column / beam structure according to the fourth embodiment, and FIG. It is BB arrow sectional drawing of FIG. In FIG. 11, the glass plate 30 and the sealing material 35 are not shown for convenience of explanation.

  As shown in FIG. 10, in the column / beam structure according to the present embodiment, a string member 60 is attached to each column member 10 as an auxiliary structure member. The string member 60 is a substantially arc-shaped reinforcing member that extends along the axial direction of the column member 10 in a vertical plane including the column member 10. ).

  Specifically, as shown in FIG. 11, the string member 60 is provided with a plurality of (six in FIG. 10) linear steel bars 62 and the ends of the steel bars 62 arranged at both ends of the steel bars 62. An end fitting 63 and a gusset plate 64 to which the end fitting 63 is bolted on both upper and lower sides are constituted. The bundle member 61 is a connecting member made of a steel bar, a steel pipe, or the like. The bundle member 61 extends horizontally between the column member 10 and the string member 60, and one end thereof is connected to the gusset plate 64. , The other end is connected to the joint between the column member 10 and the beam member 20.

  As described above, the string member 60 is formed by joining a plurality of steel bars 62 by the end metal fittings 63 and the gusset plates 64 so as to form a substantially arc shape as a whole. The substantially arc-shaped string member 60 is attached to the pillar member 10 by a plurality of bundle members 61 having different lengths so as to be disposed at a position separated from the pillar member 10. Note that the gusset plate 64 is directly joined to the column member 10 without the bundle member 61 at the upper and lower ends of the string member 60.

  By installing such a string member 60, as shown in FIG. 12, it is a cross section of the steel bar 62 of the string member 60 at a position far away from the column member 10 in the vertical direction (horizontal direction) of the finished surface. Since the number of structural sections can be increased, the column member 10 can be effectively reinforced to increase the rigidity of the column / beam structure.

  Furthermore, as a result of providing the string member 60 as described above, the width in the vertical direction of the finished surface in the cross section of the column member 10 can be reduced as shown in FIG. That is, as in the first embodiment (FIG. 3), in the case of a column / beam structure in which the string member 60 is not installed, if the width in the vertical direction of the finished surface of the column member 10 is not increased, The rigidity as a structural material could not be secured. In contrast, when the string member 60 is reinforced by attaching the string member 60 to the column member 10 as in the present embodiment (FIG. 12), the column The rigidity of the entire beam structure can be ensured.

  For this reason, as shown in FIG. 12, the column member 10 according to the present embodiment is provided with a U-shaped groove 18 having a U-shaped cross section as a clamping portion 19 for clamping the glass plate 30 on both sides in the inner direction of the finished surface. It has a compact cross-sectional shape. Specifically, the column member 10 according to the present embodiment includes, for example, a flat plate portion 16 erected with respect to the finish surface direction, and a cross section disposed symmetrically on both sides of the flat plate portion 16 in the vertical direction of the finish surface. A semi-circular flange portion 17 and a holding portion 19 including a groove portion 18 formed by the flat plate portion 16 and the bottom portions 17a of the pair of flange portions 17 are provided. The clamping part 19 composed of the members constituting the groove part 18 (the bottom part 17a of the pair of flange parts 17 and the flat plate part 16) is structurally similar to the clamping part 24 of the beam member 20 of the first embodiment. Included in the cross section. The sandwiching portion 19 is configured such that the outer peripheral end portion of the glass plate 30 inserted into the groove portion 18 with a predetermined engagement allowance is applied to the sealing material 35 by the both side walls of the groove portion 18 (the bottom portions 17a of the pair of flange portions 17). Can be held through.

  As described above, in this embodiment, the string member 60 is provided as the auxiliary structural member to reinforce the column member 10, whereby the width in the vertical direction of the finished surface of the column member 10 can be reduced. The string member 60 may be installed on both sides of the column / beam structure in the vertical direction of the finished surface, or may be installed only on one side.

  The structure of the column / beam structure according to the first to fourth embodiments has been described above. Here, the example of the construction method of the pillar and beam structure concerning the said embodiment is demonstrated.

  As a first construction method, for example, first, the column material 10 and the beam material 20 are manufactured integrally by hot-pressed steel at a steel material manufacturing factory, and then, at the construction site, the column material 10 and the beam material 20 are manufactured. As the assembly is completed, a finished surface material such as a glass plate 30 is fitted at any time (for example, after a plurality of column members 10 are erected, a single beam member 20 is joined between the column members 10. There is a method of sandwiching and fixing the finishing surface material in the frame surface by the column material 10 and the beam material 20.

  As a second construction method, for example, first, a plurality of members (see, for example, FIG. 5) constituting the column member 10 and the beam member 20 are manufactured with hot-pressed steel in a steel manufacturing factory, and then the construction is performed. At the site, the pillar material 10 and the beam material 20 are assembled to construct a basic structure of the pillar / beam structure, and further, one side member (a steel material including the protrusion 13 such as FIG. After attaching the holding member 102 on one side, a finishing surface material such as a glass plate 30 is installed, and thereafter, the other member constituting the holding portions 14 and 24 (for example, holding on the other side in FIG. 5) There is a method of attaching and fixing the finished surface material by attaching the member 102).

  Further, as a third construction method, for example, a pillar material 10 having a sandwiching portion 14 and a beam member 20 not having a sandwiching portion 24 are manufactured in a steel material manufacturing factory, and then the pillar material 10 and The beam member 20 is assembled to construct a column / beam structure, and then a finishing surface material such as a glass plate 30 is attached to each lattice space surrounded by the column member 10 and the beam member 20 so that a finishing surface material such as a glass plate 30 is attached. There is a method of fitting into the holding part 14 and fixing. At this time, since the size of the finishing surface material is designed so that the edge clearance Q is generated in the clamping portion 14 of the column material 10, it is not possible to fit the finishing surface material after the column / beam structure is constructed. Is possible.

  The column / beam structure according to the first to fourth embodiments has been described in detail above. According to the column / beam structure according to the above-described embodiment, the column material 10 and the beam material 20 which are structural materials, and the support members (the sandwiching portions 14, 24, 19) that support the finished surface material such as the glass plate 30 are provided. Since it can be comprised with the same member, the number of parts for building the wall of a building structure and its manufacturing cost can be reduced. Furthermore, compared with the case where the said structural material and a supporting member are made into a separate member, the complexity of the construction accompanying the assembly of each member can be improved, construction can be facilitated, and the construction cost and construction period can be reduced.

  In particular, by manufacturing the column member 10 and the beam member 20 using hot stamped steel, the structural cross section and the support member can be integrally formed, so that the number of parts can be further reduced. Further, even when the structural cross section and the support member are formed by separate members (see FIG. 5 and the like), the sandwiching portions 14, 24, and 19 that function as the support member are made of steel. Compared to the case of using an alloy sash frame (see Patent Document 1 above), the steel column 10 and the beam 20 main body can be easily joined (for example, welding, bolt joining, etc. can be easily joined). is there. Furthermore, unlike the prior art (see Patent Document 1 above), it is not necessary to crimp and join the structural material and the sash frame, so that the assembly is easy and the workability is improved. The limit on accuracy can be relaxed.

  In addition, since the pillar / beam structure is fundamental, the type of finishing surface can be selected freely. Moreover, it can replace with a finishing surface material, and can also be set as a wall structure by installing the reinforced steel plates 40, such as a reinforced steel plate.

  Further, since all members such as the column member 10, the beam member 20, the bracing member 50, and the string member 60 are made of steel, each member can be easily joined by welding, bolt joining, etc., and assembly work is easy. is there.

  In addition, since the holding portions 14, 24, and 19 which are support members for supporting the finished surface material are included in the structural section, not only the load bearing the finished surface material but also the heavy load of the building structure can be borne. .

  In addition, by installing a reinforcing surface material such as the reinforcing steel plate 40 in place of the finished surface material, or by additionally installing the bracing material 50, the column / beam structure can be made an earthquake resistant / damping wall. Moreover, the rigidity of the column / beam structure can be further increased by combining with other structures such as the string member 60 described above.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the above-described embodiment, the example in which the holding portions 14 and 24 are provided in both the column member 10 and the beam member 20 has been described. However, the present invention is not limited to this example, and either the column member 10 or the beam member 20 is provided. Only the holding portion may be provided.

  In addition, the cross-sectional shapes of the column member 10 and the beam member 20 are not limited to the example of the above-described embodiment, and any cross-sectional shape can be used as long as the finish surface material such as the glass plate 30 can be sandwiched. It's okay. For example, the cross-sectional shape of the column member 10 may be a cross-sectional shape (see FIG. 2) having a groove-like clamping portion 24 like the beam member 20 according to the first embodiment. The cross-sectional shape is a cross-sectional shape (see FIG. 3) having a protruding clamping portion 14 like the column material 10 according to the first embodiment, or a groove shape like the column material 10 according to the fourth embodiment. It is good also as a cross-sectional shape (refer FIG. 11) which has the clamping part 19 of this.
