Description

[Technical Field]

[0001] The present invention relates to a wooden surface lattice panel that is assembled within a frame in a state where a plurality of wooden lattice members intersect with each other to form a plurality of lattice spaces, and is configured by fitting a frame that forms the periphery of the panel into the space between adjacent columns and the cross members that are arranged above and below a wooden frame building structure that is made up of a plurality of columns arranged side by side and cross members that are arranged above and below the columns, and is configured so that the frame can be freely connected to the columns and the cross members. [Background technology]

[0002] Traditionally, the wooden lattice panels have been used to reinforce buildings by connecting them to the columns and cross members of wooden frame structures to form walls, thereby improving the design, ventilation, and lighting of the building. However, in order to further reinforce the wooden lattice panels and increase the reinforcing effect of the building, it has been considered to provide lattice reinforcing devices that are incorporated into at least some of the multiple lattice spaces and fixed to the horizontal and vertical members of the lattice members to reinforce the lattice spaces. For example, the lattice reinforcement device is made of metal and consists of a closing portion having the same shape as the opening of the lattice space, and a fixing portion extending perpendicular to the closing portion, and the fixing portion is connected and fixed to the horizontal member and the vertical member (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-13600 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional lattice reinforcement devices described above, the openings of the lattice spaces are blocked by blocking parts of the same shape as the openings, and the more lattice reinforcement devices are installed in multiple lattice spaces to reinforce a building, the more the design, breathability, and lighting properties of the surface lattice panel are hindered.

[0005] Therefore, an object of the present invention is to solve the above problems and to further improve the strength of buildings while taking advantage of the advantages of surface grille panels. [Means for solving the problem]

[0006] A first characteristic feature of the wooden surface lattice panel of the present invention is that, for a wooden frame building structure having a plurality of columns arranged side by side and cross members arranged above and below, a frame forming the periphery of the panel is fitted into the spaces between adjacent columns and the cross members arranged above and below, so that it can be freely connected to each of the columns and cross members, and the wooden surface lattice panel is assembled within the frame in a state where a plurality of wooden lattice members cross each other to form a plurality of lattice spaces. In this state, lattice reinforcing devices are provided that are incorporated into at least some of the plurality of lattice spaces and fixed to the cross members and vertical members of the lattice members to reinforce the lattice spaces, and the lattice reinforcing devices have elastically deformable metal reinforcing parts that connect adjacent cross members and vertical members at each corner of the lattice spaces while maintaining the insertion parts of the lattice spaces that can let in light.

[0007] According to a first characteristic configuration of the present invention, a lattice reinforcement device is provided with elastically deformable metal reinforcement parts that connect adjacent horizontal members and vertical members at each corner of the lattice space while maintaining the insertion parts of the lattice space that allow light to enter.The metal reinforcement parts that connect to the horizontal members and vertical members of the lattice members absorb lateral external forces that act on the building due to vibrations such as earthquake forces and wind pressure through their elastic deformation, contributing to preventing or reducing destruction of the wooden lattice panel and destruction of the building that results from that destruction. Furthermore, the structure that maintains the insertion section allows the lighting and ventilation provided by the wooden lattice space to be maintained.

[0008] The second characteristic configuration of the present invention is that the lattice reinforcement device is made up of a plurality of members each having the metal reinforcement part, and is provided with a first connecting part to the horizontal member and a second connecting part to the vertical member so as to be particularly attachable at each corner of the lattice space so as to surround the inside of the lattice space.

[0009] According to the second characteristic configuration of the present invention, in addition to being able to achieve the above-mentioned advantageous effects of the first characteristic configuration of the present invention, the lattice reinforcement device is made up of a plurality of metal reinforcement parts that can be specially attached to each of the corners of the lattice space so as to surround the inside of the lattice space, so that it can be used with wooden lattice panels with lattice spaces of different sizes, improving versatility. Therefore, it is possible to improve the economy.

[0010] A third characteristic configuration of the present invention is that both end portions of the metal reinforcing portions are fixed to the vertical members and the horizontal members at the first connecting portions and the second connecting portions within the lattice space so as not to tilt at least in a direction along the lattice surface formed by the horizontal members and the vertical members.

[0011] According to the third characteristic configuration of the present invention, the metal reinforcing parts are stably and firmly fixed to the vertical members and the horizontal members at the first connecting parts and the second connecting parts, respectively, at both ends so as not to tilt at least in the direction along the lattice surface formed by the horizontal members and the vertical members (the direction of arrow D shown in Figure 2), so that bending moments are easily transmitted and reaction forces are easily generated against external forces acting on the lattice.

[0012] In a fourth characteristic configuration of the present invention, the lattice reinforcing device is made of a metallic cylindrical member, and is fitted into the lattice space so as to contact the vertical members and the horizontal members.

[0013] According to the fourth characteristic configuration of the present invention, a lattice reinforcement device formed from a metal cylindrical member makes it possible to easily reinforce multiple lattice spaces simply by fitting it into multiple lattice spaces, and yet maintains the insertion portions of the lattice spaces.

[0014] A fifth characteristic feature of the present invention is that the metallic cylindrical member is provided with a first connecting portion that is fixed to the horizontal member and a second connecting portion that is fixed to the vertical member.

[0015] According to the fifth characteristic configuration of the present invention, by simply fitting a metal cylindrical member into the lattice space and fixing it with the first connecting portion and the second connecting portion, it is possible to support the lattice against external forces acting in a direction along the surface of the lattice.

[0016] In a sixth characteristic configuration of the present invention, the first connecting portion and the second connecting portion are fixed to the vertical member and the horizontal member by special screws.

[0017] According to the sixth characteristic configuration of the present invention, the first connecting portion and the second connecting portion, which are fixed to the vertical member and the horizontal member by special screw fastening, not only can easily fix the lattice reinforcement device to the lattice, but can also be easily removed for repair.

[0018] A seventh characteristic configuration of the wooden frame building structure having the wooden surface lattice panel of the present invention is that the frame is connectable between the columns and the cross members by means of first connecting pins, and the first connecting pins are configured to be removable from the lattice space, making the surface lattice panel detachable in the horizontal direction from the space surrounded by the columns and cross members.

[0019] According to the seventh characteristic configuration of the present invention, the wooden surface lattice panel can be easily inserted between the pillars and cross members of a building for reinforcement by using the first connecting pin, and by removing the first connecting pin from the lattice space, the wooden surface lattice panel can be easily removed from the space surrounded by the pillars and cross members, and the fitting position of the wooden surface lattice panel relative to the building can be easily changed.

[0020] The eighth wooden surface lattice panel of the present invention is characterized in that the lattice reinforcing devices are provided in a dispersed manner in each of the plurality of lattice spaces.

[0021] According to the eighth characteristic configuration of the present invention, by distributing lattice reinforcement devices among multiple lattice spaces of a wooden surface lattice panel, the overall design and the reinforcing effect of the lattice panel can be easily changed.

DETAILED DESCRIPTION OF THE INVENTION

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. Figures 1 and 2 show a wooden surface lattice panel 5 assembled within the frame 3 in a state where a frame 3 that forms the periphery of the panel is fitted into the space between adjacent columns 1 and the horizontal members 2 that are arranged above and below the columns 1, allowing for free connection to each of the columns 1 and the horizontal members 2, for a wooden post-and-beam architectural structure having multiple columns 1 arranged side by side and horizontal members 2 (bases, girders, beams, girder sections, etc.), and multiple wooden lattice members 4 are crossed with each other to form multiple lattice spaces S. In architectural structures, this wooden surface lattice panel 5 has excellent breathability and lighting properties, and is excellent in Japanese design like a transom, and can be installed in partition walls and windows that are useful for earthquake reinforcement without compromising the sense of openness.

[0024] As shown in Figures 5 to 7, the connection structure between the multiple lattice members 4 is constructed by assembling them together using general half-notching processing, and the connection structures between the ends of the lattice members 4 and the vertical frames 3A and horizontal frames 3B as the frame 3 are each assembled using mortise and tenon processing. The wooden surface lattice panel 5 may have its lattice members 4 with a large or small crossing interval, which is selected depending on the design and the strength of the surface lattice itself.

[0025] As shown in Figures 1 to 8, the wooden surface lattice panel 5 is incorporated into at least some of the multiple lattice spaces S, and is provided with a lattice reinforcing device 6 that is fixed to the vertical members 10 and horizontal members 11 of the lattice member 4 to reinforce the lattice spaces S, and the lattice reinforcing device 6 is equipped with an elastically deformable metal reinforcing part 6A that connects between the adjacent horizontal members 11 and vertical members 10 at each corner of the lattice space S while maintaining the insertion part 7 of the lattice space S that can let in light.

[0026] As shown in FIGS. 1 to 6, the lattice reinforcement device 6 is composed of a plurality of sheet metal reinforcement members 8 each having a metal reinforcement portion 6A, and is provided with first connecting portions 12 (connecting portions) for the horizontal members 11 and second connecting portions 13 (connecting portions) for the vertical members 10 so as to be attachable separately (at four locations) at each corner of the lattice space S so as to surround the inside of the lattice space S. The sheet metal reinforcing member 8 is made of, for example, a strip of steel sheet metal having the shape shown in Figures 4 and 5, and has connecting sections (first connecting section 12 and second connecting section 13) at both ends, each with a cross member 11 and a vertical member 10 of the lattice member 4 that intersect with each other at 90 degrees, and screw holes for fastening screws 23 to the frame 3, and bent sections 14 at three locations between the two connecting sections. In other words, the sheet metal reinforcing member 8 is configured to allow stress to be concentrated at the bent portion 14, making it prone to elastic deformation, so that it can withstand external forces acting horizontally and vertically on the entire surface grille panel 5 and function to mitigate the action of the external forces.

[0027] Next, as shown in Figs. 1 and 2, a mounting structure for a wooden surface lattice panel 5 to a wooden framework building structure will be shown. In a wooden frame building structure, a frame 3 that forms the periphery of the panel is fitted into the space between adjacent columns 1 and the cross members 2 arranged above and below, and the cross members 2 connected to the foundation and the lower cross frame 3B of the lattice panel 5 are detachably attached at two points along their length via a pair of first connecting pins 16 that can be fitted together and connected to each other, and anti-slip drift pins (not shown) that fit into drift pin holes 26 formed in each of the first connecting pins 16, and the cross members 2 and the frame 3 are connected to each other by the fitting connection of this pair of first connecting pins 16. The upper cross member 2 such as a beam and the upper horizontal frame 3B of the surface grille panel 5 are detachably connected at two points in their longitudinal direction by a pair of first connecting pins 16, similar to the lower side. In addition, the parallel columns 1 and the vertical frame 3A of the surface grille panel 5 are connected at four locations in the vertical direction via a pair of first connecting pins 16 that can be fitted together and connected to each other, allowing for free attachment and detachment (Figures 1, 6, and 7). As described above (shown in FIGS. 1, 2, 6 and 7), the first connecting pin 16 is made up of a convex pin 16A and a concave pin 16B that can be fitted together to connect to each other. As shown in Figures 6, 7, 10(a) and 10(b), the rear end of the convex pin 16A has a female thread 16X (25), into which a male thread for removal is screwed and by performing the removal operation from the lattice space S (Figure 10(a)), the surface grille panel 5 can be freely attached and detached in the horizontal direction (the direction perpendicular to the lattice surface of the surface grille panel) (Figure 10(b)). Each pin (16A, 16B) has a through hole 16Y formed in a direction perpendicular to the longitudinal direction of the pin, and by appropriately driving a nail or drift pin into this through hole 16Y (drift pin hole 26 in Figures 6 and 7), the first connecting pin 16 can be prevented from coming loose. The lower cross member 2 is placed on a concrete foundation beam 15, and a second connecting pin 18 connected to the upper end of an anchor bolt 17 attached to the foundation beam 15 at the middle of its longitudinal direction is fitted into a sheath pipe 19 installed in a recess formed on the underside of the cross member 2, causing the pin to bear shear force against external lateral forces (Figures 1 and 8).

[0028] A joint 1A between a column 1 and a cross member 2 of an architectural structure is connected by a beam support metal fitting 20 attached to the beam and a bolt 21 attached to the column 1, as shown in FIGS. In detail, a bolt 21 is passed through the pillar 1 to fix the beam support hardware 20 to the pillar 1. Then, the column 1 and the cross member 2 are connected by aligning the multiple holes formed in the cross member 2 with the multiple holes in the beam support hardware 20 inserted into the slit in the cross member 2 and driving multiple drift pins into them. Although not shown, a similar beam support metal fitting 20 may protrude from the right side of FIG. 2 in some cases, and a similar structure may continue.

[0029] There is a small clearance between the multiple holes in the beam support hardware 20, the multiple holes in the cross member 2, and the drift pins, and when the angular change between the column 1 and the cross member 2 is small, the joint 1A between the column 1 and the cross member 2 has a structure that does not actually transmit bending moments in response to horizontal loads (in terms of structural mechanics, it is a pin joint, not a rigid joint). Therefore, the first connecting pins and second connecting pins 18 allow the wooden surface lattice panel 5 to bear the shear force caused by longitudinal displacement of the columns 1 and cross members 2 of the wooden frame building structure. That is, as shown in Figure 11(a), when a lateral load F is applied, a force as shown by the arrows is generated in the column 1 and the cross member 2, and a shear force acts on the first connecting pin 16 and the second connecting pin 18, and as shown in Figure 11(b), a small displacement and force are generated in each lattice unit 5A that expands the angle α and reduces the angle β. The lattice reinforcement device 6 of the surface grille panel 5 generates a reaction force against this minute displacement and force, and the surface grille panel 5 as a whole protects the entire structure from the lateral load F with the shear force described above.

[0030] [Another embodiment] Other embodiments will be described below.

[0031] <1> The structure of the surface lattice panel 5, in which the multiple lattice members 4 intersect with each other, is not limited to one in which the horizontal members 11 are horizontal and the vertical members 10 are vertical, but may also be one in which the horizontal members 11 and vertical members 10 intersect with each other in an oblique direction, thereby making it possible for the entire building structure to function as a load-bearing wall that can increase the earthquake resistance strength. <2> Although the lattice reinforcing devices 6 are attached to the four corners in the example shown, they may be attached to two or three or fewer locations. <3> As shown in Figures 9(a) and (b), the lattice reinforcement device 6 comprises a metal cylindrical member 22 fitted into the lattice space S, and the metal cylindrical member 22 may be provided with a first connecting and fixing portion 12 for the horizontal member 11 and a second connecting and fixing portion 13 for the vertical member 10.

[0032] As mentioned above, although reference numerals are used for the purpose of easy comparison with the drawings, the present invention is not limited to the configurations shown in the drawings, and it goes without saying that the present invention can be embodied in various forms without departing from the spirit and scope of the present invention.
