Abstract

<P>PROBLEM TO BE SOLVED: To facilitate assembling by securing tenacity as an aseismatic reinforcing wall while securing opening performance of a building. <P>SOLUTION: An outside vertical frame material 2 and vertical-horizontal lattice materials 31 and 3 are formed of an Oregon pine, and surround tempered glass 1. The vertical frame material 2 and the lattice material 31 of the aseismatic reinforcing wall are fixed to a girder 4 and a sill 5 by a structural metal fitting. Beads 10 and 11 are oppositely arranged in an installation part of the tempered glass 1 of the lattice materials 31 and 3, and the glass 1 is sandwiched between these beads. The tempered glass 1 is fixed to the lattice materials 31 and 3 via a resin layer. Strength is increased by fixing structural plywood 60 and 61 to wall upper-lower parts having no influence so much on natural lighting. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a seismic wall mainly made of glass of a wooden building.

  If a seismic wall is provided for seismic reinforcement, the lighting surface is limited, the openness of the building is impaired, and a comfortable living space cannot be formed. It is important to add a horizontal strength element without compromising openness.

  Although it has been proposed to use transparent glass as an earthquake-resistant reinforcing wall to ensure openness, relatively large glass is supported by a frame, and even tempered glass is made of a brittle material. There is a problem that the glass is broken when the force is applied suddenly or when the force is applied intensively.

  In Patent Document 1, in order to provide seismic reinforcement while maintaining the openness of an old Japanese-style house, the seismic reinforcement panel with a glass plate attached to the frame material is screwed to the wooden part of the wooden building. A reinforcing structure is disclosed. Before the frame is deformed by the seismic force and the glass is broken, the screw is sunk into the xylem so that the force is not directly applied to the glass to prevent the glass from being broken. Also, the glass is fixed to the frame material via the structural seal, and the screw is sunk by the seismic force and reaches the yield point. It is like that.

However, the frame is relatively large and it is necessary to drive the screws accurately, but the construction accuracy is not so high, and the seismic reinforcement effect may not be exhibited as set. In addition, the assembly is troublesome because of the structural seal and the silicon sealing.
Japanese Patent Laid-Open No. 10-184030

  Therefore, the seismic reinforcement wall using glass is capable of exhibiting the tenacity while ensuring the openness of the building, and facilitates the assembly.

In order to solve these problems, in a seismic reinforcement wall using glass, the glass is surrounded by a wooden lattice frame as a structural material, and the glass can be embedded into the lattice frame according to the deformation of the lattice frame. is there.
A rice pine is used as the lattice frame, a pair of pressing edges is provided on the lattice frame, and the glass is fixed to the lattice frame by inserting the glass into the space between the pressing edges.

According to the present invention, a seismic reinforcing wall in which glass is fitted in a lattice frame is effective as a seismic reinforcing wall because it is excellent in daylighting, provides openness to a building space, and can improve rigidity.
In addition, the seismic reinforcement wall using a wooden frame and a glass plate secures the openness of the wooden building, and because it uses wooden members, it is excellent in design.

  As shown in FIG. 1, in the seismic reinforcement wall, the outer vertical frame member 2 is 105 × 105 (mm) rice pine, and the vertical and horizontal lattice members 31 and 3 are 90 × 105 (mm) rice pine. The tempered glass 1 is surrounded. The seismic reinforcement wall is fixed to the girder 4 and the base 5 with structural metal fittings or the like. The wood has an appropriate hardness for the rice pine to bite the tempered glass when the lattice frame is deformed.

As shown in FIG. 2, holding edges 10 and 11 are provided facing each other at the attachment portions of the tempered glass 1 of the lattice members 31 and 3, and the glass 1 is sandwiched therebetween. The tempered glass 1 is fixed to the lattice members 31 and 3 via an epoxy resin layer 12 of about 3 to 8 mm and a polycetal resin layer 13 of about 2 to 3 mm. In addition, since glass is weak when force is applied to the corner portion, the corner portion is not filled with resin.
You may make it a tempered glass contact a timber directly at the time of a deformation | transformation, without providing a resin layer.

  The vertical frame member 2 is fixed to the base 5 with fixing brackets 20 and 21 as shown in FIG. Further, as shown in FIG. 3 (2), the upper part is fixed to the girder 4 with fixing brackets 22 and 23. Structural plywoods 60 and 61 are fixed to the upper and lower parts of the wall that do not affect lighting so much that the seismic reinforcement walls are strengthened.

  The lattice members 31 and 3 are fixed to the vertical frame member 2, the girder 4, and the base 5 with a short mortise. As shown in FIG. 4, the intersection of the lattice material 3 and the lattice material 31 is assembled by providing a cutout 51 in each of the lattice materials 31 and 3. The cutouts 51 formed in the vertical lattice material 31 are alternately formed on the front and back sides so that the cutouts 51 are not formed on the same surface.

Test Example Strength was measured using a wall having a wall width of 910 mm and a height of 2700 mm. The force and measurement method applied during the test were carried out in accordance with the “Allowable Stress Design Method for Wooden Shaft Construction Methods”, and the tie rod type was used as the loading method. Table 1 shows the properties of the materials, and Table 2 shows the metal fittings.

The calculation of the characteristic value of the joint is as follows.
The short-term reference shear strength P ₀ of the test specimen was set to the minimum value among a to d shown in Table-3. The short-term allowable shear strength Pa and wall magnification were calculated by the following equations.

Pa = P ₀ × α
P ₀ : Short-term reference shear strength, α: α = 1 in this evaluation.
Wall magnification = Pa × (1 / 1.96) × (1 / L)
Pa: Short-term allowable shear strength 1.96: Numerical value for calculating wall magnification = 1 L = Wall length The short-term reference moment was calculated according to the allowable stress design of the wooden frame construction method house. (In this test, the variation coefficient is set to 1 because it is one body.)

Table maximum shear strength Pmax as shown in -3 short reference shear strength P ₀ and greater than the short-term allowable shear strength Pa, proved to have sufficient earthquake resistance.
