Description

  The present invention relates to a building structure and a load-bearing panel of a building such as a wooden frame house.

  As a wooden frame building, a structure as disclosed in Patent Document 1 below is known.

  That is, with reference to FIG. 9, a panel is attached to a housing 103 having a floor set 101 and a shaft set 102, and a floor panel 104 (rough floor) is placed on the floor set 101. The outer wall panel 106 and the partition panel 107 are fixed between the column members 105 of the shaft set 102.

  The partition panel 107 is formed at the same height as the room size and is built on the floor panel 104. For this reason, the ceiling board 108 is put on the built-in partition panel 107.

  Because of this structure, the plurality of rooms partitioned by the partition panel 107 share the floor panel 104 and the ceiling plate 108. Further, the space below the floor panel 104 and the space above the ceiling board 108 communicate with those in the adjacent rooms.

  For this reason, even if the partition panel 107 is built between the column members 106 erected as the shaft assembly 102, the upper and lower ends thereof are fixed to the floor panel 104 and the ceiling plate 108. It is not fixed to the floor assembly 101 or the shaft assembly 102. For this reason, the partition panel 107 is weakly connected to the floor assembly 101 and the shaft assembly 102, and even if the strength of the partition panel 107 itself is increased, it cannot be fully utilized.

  Further, since the floor panel 104 and the ceiling board 108 are common to those in a plurality of adjacent rooms, vibrations transmitted to the floor panel 104 and the ceiling board 108 in one room are transmitted to those in other adjacent rooms. Further, as shown by the arrows in the drawing, it is also transmitted through a communicating space. For this reason, there was room for improvement in terms of soundproofing.

JP 2000-220215 A

  Accordingly, the main object of the present invention is to increase the strength of the building, improve the earthquake resistance, and improve the sound insulation.

  For that purpose, there are a frame surrounding the outer periphery, a rod-shaped support material stretched inside the frame, and a plate-shaped stretch inside the frame and in the middle in the thickness direction of the frame. A building structure is provided in which a load-bearing panel having a core material is provided, and the load-bearing panel is fitted between horizontal members spaced apart in a vertical direction in a building.

  In other words, a load-bearing panel having a frame, a support member, and a core member is a panel that has high rigidity and can be used as a load-bearing wall. It is directly fixed between the upper and lower horizontal members such as and supports the horizontal members. In addition, the load-bearing panel makes the space partitioned by this independent of the indoor portion as well as the under floor portion and the ceiling back portion.

  A plate-like base material may be attached to both sides of the load-bearing panel and used as a partition wall and / or an external wall. The presence of the base material further increases the rigidity of the load-bearing panel, and when used as an external peripheral wall, the work of fixing the inner wall member can be omitted.

  Of the horizontal members spaced apart in the vertical direction above, if the lower horizontal member is the foundation provided on the fabric foundation of the building, the space partitioned by the load-bearing panel is more completely independent Can be made.

  Another means includes a frame surrounding the outer periphery, a rod-shaped support material stretched inside the frame, and a plate-shaped stretch inside the frame and in the middle in the thickness direction of the frame. A load-bearing panel having a core member and formed on the upper end surface and the lower end surface of the frame body with an abutment surface that abuts against an opposing surface of a horizontal member spaced apart in the vertical direction in the building. It is characterized by that.

  In other words, the abutment surfaces at the upper and lower ends of the frame can be fixed in a state where they abut against the opposing surfaces of the horizontal member, support the load applied to the horizontal member, and close the space between the horizontal members.

  As described above, according to the present invention, the frame body that surrounds the outer peripheral portion, the rod-shaped support member that is stretched inside the frame body, and the plate-shaped core material that is stretched inside the frame body are provided. The load-bearing panel is fitted and fixed between horizontal members spaced apart in the vertical direction in the building.

  For this reason, the load-bearing panel plays a role of directly supporting the horizontal member while partitioning the space. In addition, the load-bearing panel having the frame body, the support member, and the core member has high strength and can form a load-bearing wall.

  Therefore, the strength of the building can be improved by taking full advantage of the property that the load-bearing panel has high strength, and good earthquake resistance can be obtained.

  In addition, the load-bearing panel is fixed between the horizontal members, and the space partitioned by the load-bearing panel can be made independent at both the under floor portion and the ceiling back portion. That is, since the floor board and the ceiling board are divided for each space, vibrations and the like are hardly transmitted. In addition, in the present invention, the transmission of vibrations between adjacent rooms through the space under the floor or the back of the ceiling is conventionally only double of the floor panel and ceiling plate. In addition to being partitioned by the floor plate and ceiling plate, it is also partitioned by the load-bearing panel, so that it is partitioned in triplicate and vibrations are not easily transmitted.

  For this reason, high soundproofing can be obtained, and even if a fire occurs in a room, it is possible to prevent the fire and sparks that have risen there from moving to an adjacent room. For this reason, the load-bearing panel plays a role as a fireproof wall, and it is possible to obtain a high-performance building having not only earthquake resistance but also soundproofing and fireproofing.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a load-bearing panel 11, and FIG. 2 is an exploded perspective view thereof. The load-bearing panel 11 is used as a partition wall 12 or an outer peripheral wall 13 of a building as shown in FIGS. Used for.

  The load-bearing panel 11 includes four frame bodies 14 that vertically surround the outer periphery in a rectangular shape, bar-shaped vertical support members 15, 16... That are stretched in the vertical direction inside the frame body 14, and bar shapes that are stretched in the horizontal direction. , And plate-like core members 18, 18 that are stretched in the middle of the frame body 14 in the thickness direction.

  The frame body 14 is formed by assembling four square members 14a.

  Among the vertical support members 15, 16..., The vertical support member 15 at the intermediate position in the width W direction of the load-bearing panel 11 is set to the same thickness as the thickness T of the frame body 14. A concave groove 15a into which the edge of the core member 18 is inserted is formed. Similar concave grooves 14b are also formed on the inner side surfaces of the square members 14a constituting the frame body 14.

  Further, the other vertical support members 16 attached to both sides of the vertical support member 15 at the intermediate position are set to a thickness obtained by subtracting the thickness of the core member 18 from the thickness T of the frame body 14, and then the upper and lower ends. Is fixed to the frame body 14, and the surface facing the core member 18 is fixed to both surfaces of the core member 18.

  The horizontal support members 17 are formed to have the same thickness as the vertical support members 16 at the both sides, and both ends are fixed to the side surfaces of the frame body 14 and the vertical support members 15, 16. The surfaces opposite to each other are fixed to both surfaces of the core member 18.

  A structural plywood is used for the cores 18 and 18.

  In the illustrated example, two core members 18 are used. However, depending on the required size of the load-bearing panel 11, the core member 18 may be configured by one core member 18, and the vertical support members 15, 16. The number of supporting members 17 is not limited to that shown in the drawing.

  Each member is fixed by an appropriate method using an adhesive or a nail.

  In addition, the width W of the load-bearing panel 11 is set to a dimension that can be fitted between column members constituting the building frame, and the height H is a dimension that can be fitted between horizontal members that are spaced apart vertically. Set to. The thickness T is appropriately set depending on the aspect of the wall surface to be obtained, that is, the large wall structure or the true wall structure.

  Next, a building structure configured using the load-bearing panel 11 having such a configuration will be described.

  A plate-like base material 19 made of a structural plywood is attached to both sides of the load-bearing panel 11. Pasting can be done prior to or after installation. A soundproofing / insulating material 20 is housed inside. The soundproofing and heat insulating material 20 is formed in a square plate shape, and is fixed to the core material 18 in a rectangular space surrounded by the frame body 14, the vertical support members 15, 16. Can be stored. The soundproofing and heat insulating material 20 may be fixed to one side surface of the core material 18 depending on the thickness thereof.

  FIG. 3 is a cross-sectional view showing a partition portion of a wooden framed house. The partition portion includes a large pull 22 that forms a floor set 21, and a beam 24 of a shaft set 23 that is disposed above the large pull 22. In between, it is constructed as a partition wall 12 between the load-bearing panels 11.

  At this time, the lower end surface of the frame body 14 is an abutment surface 14 c that abuts against the large pull 22, and the upper end surface of the frame body 14 is an abutment surface 14 d that abuts against the beam 24.

  Before or after the load-bearing panel 11 is fitted, a floor and a ceiling are formed in each space partitioned by the load-bearing panel 11.

  In the figure, 25 is a joist assembled on the top, 26 is a rough floor fixed on the joist 25, 27 is a flooring fixed on the rough floor 26, and 28 is attached to a corner of the flooring. Skirting board. In the figure, 29 is a hanging tree that is suspended from the beam 24 and is attached to the ceiling board 30, and 31 is a field that is fixed to the lower end of the hanging tree 29 and receives a field edge 32 that is fixed to the upper surface of the ceiling board 30. It is a rim.

  The structure shown in the figure is an example in which the rooms on both sides partitioned by the load-bearing panel 11 are both large wall structures. In this case, as shown in the cross-sectional view of FIG. Is set to be the same as the thickness of the column member 33 and the base material 19 to be attached to both sides is set to have the same height as the height H of the load-bearing panel 11, while the length in the width direction is set to that of the load-bearing panel 11. It is set larger than the width W dimension.

  When one room has a large wall structure and the other room has a true wall structure, as shown in FIG. 7, the base material 19 on the side having the large wall structure is the same as the base material 19 shown in FIG. On the other hand, the base material 19 on the side to be a true wall structure is formed in the same size as the strength panel 11. Then, the thickness T of the frame body 14 is set slightly smaller than the thickness of the column member 33.

  In addition, when the rooms on both sides have a true wall structure, the thickness T of the frame member 14 is set to be smaller than that shown in FIG. 7, and the size of the base material 19 to be affixed on both sides is determined by the load-bearing panel. 11 is set to the same size. The soundproofing / insulating material 20 is thinner than the loadproof panel 11 shown in FIGS. 6 and 7 because the thickness of the frame body 14 is set thin. Therefore, the soundproofing and heat insulating material 20 is thinner than in the case of FIGS. 6 and 7. The heat insulating material 20 is fixed to both surfaces of the core material 18.

  When both sides have a large wall structure, when one side has a true wall structure, both may have a true wall structure. FIG. 4 shows an example in which both sides have a large wall structure. FIG. 5 shows an example of a true wall structure.

  FIG. 4 is another cross-sectional view showing the partition portion of the wooden framed house. The partition portion includes a base 34 that forms the floor set 21, and a beam 24 of the shaft group 23 that is disposed above the base 34. In between, the load-bearing panel 11 is inserted and configured as the partition wall 12.

  Before or after the load-bearing panel 11 is fitted, a floor and a ceiling are formed in each space partitioned by the load-bearing panel 11.

  In the figure, 35 is a fabric foundation, and 22 is a large fork stretched between bases 34. In addition, about the site | part same as the said structure, the code | symbol same as it is attached | subjected and the detailed description is abbreviate | omitted.

  FIG. 5 is another cross-sectional view showing the outer peripheral wall 13 portion of the wooden framed house. The outer peripheral wall 13 portion includes a base 34 forming the floor assembly 21 and a shaft disposed above the base 34. The load-bearing panel 11 is fitted as the outer peripheral wall 13 between the set 23 and the trunk 36.

  Before or after the building panel 11 is fitted, a floor and a ceiling are formed in each space partitioned by the load-bearing panel 11.

  In the figure, 37 is a tatami mat provided at the corner of the floor, 38 is a tatami mat, and 39 is a collar. Again, the same parts as those in the above configuration are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the building structure configured as described above, the load-bearing panel 11 including the frame body 14, the longitudinal support members 15, 16... And the lateral support members 17. By being fitted in a space surrounded by the base 34, the beam 24, the torso 36, and the column member 34, the positional relationship of the structural parts of these cases is firmly maintained. That is, it supports the chassis. In addition, the load-bearing panel 11 having the frame body 14, the vertical support members 15, 16... And the horizontal support members 17 and the core members 18 and 18 has high strength and can form a load-bearing wall.

  Therefore, the strength of the building is improved and good earthquake resistance can be obtained.

  In addition, since the load-bearing panel 11 is fixed in a state where it is fitted between horizontal members such as the draw 22, the base 34, the beam 24, and the torso 36, the load-bearing panel 11 is independent in each space partitioned by the load-bearing panel 11. The structure forms a floor and a ceiling. That is, since the floor and the ceiling are independent, the vibration of one room is not easily transmitted to the other room. Further, the transmission through the space under the floor or the back of the ceiling is also divided by the strength panel 11 because it is divided at the lower end and the upper end of the strength panel 11 protruding below or above the floor or ceiling surface. Space can be made independent under the floor or behind the ceiling. That is, transmission of vibration and the like through the space under the floor or behind the ceiling can be suppressed.

  For this reason, high soundproofing can be obtained, and even if a fire occurs in a room, it is possible to prevent the fire and sparks that have risen there from moving to an adjacent room. For this reason, the load-bearing panel 11 also serves as a fireproof wall, and a highly functional building having not only earthquake resistance but also soundproofing and fireproofing can be obtained.

  As in the building structure shown in FIG. 4, when the partition wall 12 is configured by inserting the load-bearing panel 11 between the base 34 and the beam 24 on the cloth foundation 35, the lower floor portion is not only near the floor, Since the entire lower side can be divided corresponding to the room, the independence of each room can be further enhanced, and the above-mentioned effects such as soundproofing and fireproofing can be further improved.

  Further, when the load-bearing panel 11 is used for the outer peripheral wall 13 as in the building structure shown in FIG. 5, the strength of the outer peripheral wall 13 can be increased due to the high strength of the load-bearing panel 11, and the inner wall member Fixing work can be omitted.

  Furthermore, since the load-bearing panel 11 is a multi-panel that can be used for the partition wall 12 and the outer peripheral wall 13, it is not necessary to prepare separate panels for the partition and the outer wall. For this reason, the kind of components required for a building can be suppressed, and it has the effect that cost reduction etc. can be aimed at.
