Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcement structure for enhancing the structural rigidity of an existing wooden building by enhancing its deformation rigidity, and more particularly to an existing wooden timber building. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal strength reinforcing structure for a building in which a reinforcing material can be easily attached from the outside and inside of the building without significantly breaking the outer wall of the building.

[0002] In the description of the present invention, indoors and outdoors are distinguished by using the outer wall of a building as a boundary, the inside as indoors, and the outside as outdoors.

[0003]

2. Description of the Related Art The opinion that "earthquake damage to a timber framed building is greatly affected by the strength of the joint" is a consensus opinion among many wooden building researchers that the joint with the highest reliability is considered. As a means of improving strength, commonly known as "Z mark display hardware"
The Japan Housing and Wood Technology Center, called
Various hardware such as hardware specified by the "Hardware Standard for Framing Method" established in 1978, similar fired hardware, bracing plates, chevron plates, and corner plates are provided.
It is also well known that hole-down hardware is provided that attaches to bases and pillars.

Further, Japanese Patent Application Laid-Open Nos. Hei 8-302834 (hereinafter referred to as Conventional Technique 1), Japanese Patent Laid-Open Publication No. Hei 8-338070 (hereinafter referred to as Conventional Technique 2), Japanese Patent Laid-Open Publication No. Hei 10-131295 (hereinafter referred to as Conventional Technique 3), Further, improved reinforcing metal fittings and structures have been proposed, such as Japanese Patent No. 2804002 (hereinafter referred to as Conventional Technology 4) and Japanese Patent No. 2896866 (hereinafter referred to as Conventional Technology 5). However, in many existing houses using the conventional frame method of wooden buildings, the above-mentioned reinforcing metal fittings are insufficiently mounted, and the brace for increasing the rigidity of the vertical construction surface has a large shape and dimension. Not only are there many buildings with insufficient wall coverage, they are also likely to be inadequately arranged, and in particular, there is a marked difference between before and after the new seismic standards. Even in subsequent buildings, there are many buildings where the amount and balance of load-bearing walls are not satisfied. And since the above-mentioned brace plate, chevron plate, and corner plate are also hardware of tension material, they are joints of horizontal members such as bases and girders and vertical members, and joints of brace members. Reinforcement of the braces has many drawbacks and also has the disadvantage of being costly.

[0005]

As described above,
Existing wooden buildings have insufficient strength, such as insufficient bracing, loosening of joint bolts due to aging, and insufficient installation of conventional reinforcing hardware. Even if it is necessary to reinforce the portion, the cost is high, such as breaking the outer wall or building a scaffold, and there is a problem that the reinforcement work is difficult in terms of cost.

Further, the prior art 1 has a structure in which the number of nails and coach bolts for mounting is large and the number of man-hours required for construction is increased, and a side plate portion in contact with wood is welded after bending. In addition, since the rubber plate is attached, the cost of fittings is high.
Since the triangular plate is a single plate, the edge is weak against compression buckling,
In addition, because of its heavy weight, it is unsuitable for work in narrow places under the floor or under the ceiling, and is difficult to apply as a metal fitting for reinforcing existing houses.

In the prior art 2 and the prior art 3, the weight reduction and the countermeasures against the compression buckling of the triangular plate portion are taken. However, the metal fitting is basically applied to a new house. There is a triangular plate on both sides, and mounting bolts are required in the space between them, so it is very difficult to apply it to existing houses, and in practice it is used as a metal fitting for reinforcing existing houses Was not applicable. In other words, even if various ideas are devised on the hardware itself, when reinforcing an existing house, if the existing pillars (indoor pillars) are weakened, or if the hardware cannot be directly attached to the existing pillars due to space constraints, However, there is a problem that a reinforcing effect cannot be expected.

Further, in the prior arts 4 and 5, a strong support base is provided on the ground, and the collapse (sideways and falling out) of the house is prevented by using the auxiliary pillars supported by the support base. Since a large bending moment is generated at the base of the auxiliary pillar, it is necessary to make the foundation structure considerably strong.
The construction cost is high, and construction in a narrow space is particularly difficult.

The present invention has been made in view of the above points, and in a pre-built timber framed building, a skeleton is reinforced by a portal structure using an outdoor column, and a joint between a column and a beam is provided. By strengthening the part with reinforcing materials, the strength and rigidity of the portal structure is improved, making it possible to improve the horizontal strength of the house while eliminating the need for large-scale foundation work, and protect the building from seismic force It is an object of the present invention to provide a reinforcement structure for a wooden building that can be used.

[0010]

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, for ease of explanation,
This will be described with reference to the drawings. FIG. 1 shows a two-story house to which the reinforcing structure of the present invention (claim 1) is applied to the left half,
The right half is a schematic front view showing a skeleton example in a state where the reinforcing structure is not applied. In FIG. 1, the horizontal force due to an earthquake or the like occurs in the left-right direction of the figure. For example, when examining the horizontal strength of the first floor 1F, the dynamic model is as shown in FIG. It may be considered that it is located at the equivalent position G, and a deformation as shown by a dotted line in FIG. 2 occurs. It can be said that the smaller the horizontal displacement at this time, the higher the horizontal proof stress. A good method for increasing the horizontal strength is to insert a member (brace) connecting the points a and d and the points b and c in FIG. 2 and securely fasten the joint with a metal fitting (reinforcing material) or the like. Is to make a bearing wall by sticking structural plywood etc. Performing such remodeling in an existing house is often difficult due to internal passageways (openings) and costs.

As a next method, the moment rigidity at points a and b in FIG. 2 is increased (a metal fastener is attached).
There is a method, but the points a and b in FIG. 2 correspond to the second floor F2 in FIG.
There is often a gap between the first floor T1 and the ceiling T1, which is commonly referred to as the middle heaven 4, and there is often no gap enough to allow a person to enter, and it is not unusual for the mounting work of the metal fittings to be impossible.

Therefore, according to the method of the present invention, the outdoor column 1 (the right half of FIG. 1 is not shown) for reinforcement outdoors is positioned opposite to the position of the indoor column 2 already installed indoors. The outdoor pillar 1 is fastened to the existing indoor pillar 2 with a fastener 3 (such as a coach screw or a screw), and at the same time, the base 20, the rim 21a, and the eaves girder 21b are also fastened with the fastener 3. Fastening to increase the bending stiffness of the indoor column 2 and make it easier for humans to enter
(Points e and f in FIG. 2), by reinforcing the joint (joint portion) between the upper beam 7 and the indoor pillar 2 laid on the indoor pillar 2 with the reinforcing material 6, The generated horizontal force is received by a portal formed by an indoor pillar 2 reinforced by an outdoor pillar 1 and an upper ceiling beam 7. In this case, the left and right outdoor pillars 1, 1
It is most preferable that the upper beam and the upper beam 7 form a portal structure,
It is needless to say that in a place where the outdoor pillar 1 stands on only one side, it is effective to use a semi-portion-type configuration with one outdoor pillar 1 and the upper ceiling beam 7.

As a result of calculation when a horizontal force of 100 kg was applied to the point G in FIG. 1, the horizontal displacement when the reinforcing bracket (not shown) was attached to the middle beam 40 was 4.4 cm. On the other hand, in the reinforcing structure of the present invention, the horizontal displacement is 2.0
cm and a horizontal stiffness more than about twice as high as that of the first embodiment.

As the reinforcing material 6 for reinforcing the upper beam 7, it is preferable to use a long metal truss material. Since the bending strength is concentrated on the upper beam 7, reinforcement for the purpose of increasing the rigidity and strength of the beam is important. For this purpose, as a truss member,
As shown in FIG. 1, it is the most rational reinforcement method to attach a reinforcing member 6 that forms a triangle of a vertical construction surface of the upper beam 7, which is efficient. In addition, it is preferable that the outdoor pillar 1 is fastened to the foundation 8 by a fastener 3a or the like. Alternatively, it is preferable that an additional foundation is struck for the outdoor column 1 and anchored. However, since the structure is supported as a portal, an underground foundation for the outdoor column 1 may not be provided. In other words, since it is a reinforcement structure that suspends from above with a gate structure against horizontal force, it is possible to avoid generating a large bending moment at the base of the outdoor column, and therefore, an underground foundation for building the outdoor column This can be unnecessary or simplified, which is advantageous in terms of the construction cost and construction period associated with the underground foundation work, and enables construction in a narrow space. Moreover, since the fastener 3 penetrates the outer wall 22 when fastening the outdoor pillar 1 and the indoor pillar 2, it is necessary to perform sealing against rain.

Next, FIG. 3 shows a two-story house.
It is a typical perspective view showing a part of example of a frame in the state where a reinforcement structure (claim 2) of the present invention was applied. This reinforcing structure is a frame structure of a wooden building.
The outdoor pillars 1 and 1 are provided along the outer wall at a position not opposed to the indoor pillar 2 so as to form a pair, and the outdoor pillars 1 and 1 and the existing indoor beam (existing upper ceiling beam 7a) are provided. The joint portion (joint portion) is reinforced with a reinforcing material 6a, and as a frame, a portal structure is formed by the outdoor columns 1, 1 and the existing upper beam 7a. The outdoor pole 1 is reinforced by being fastened to the base 20, the rim 21a, and the eaves girder 21b with the fastener 3. Further, as shown in the example of FIG. 3, it is preferable that the joint between the upper beam 7 originally mounted on the indoor column 2 and the indoor column 2 is also reinforced with the reinforcing material 6.

Next, FIG. 4 shows a two-story house.
It is a typical perspective view showing a part of example of a frame in the state where a reinforcement structure (claim 3) of the present invention was applied. This reinforcing structure is a frame structure of a wooden building.
The outdoor pillars 1, 1 are provided along the outer wall at a position not opposed to the indoor pillar 2 so as to form a pair, and a new indoor beam (new The upper pillar 7b) is provided, and the outdoor pillars 1, 1 and the new upper beam 7b are provided.
The joint (connecting part) with the reinforcing member 6b is reinforced with a reinforcing material 6b, and as a frame, a portal structure is formed by the outdoor columns 1, 1 and the new upper beam 7b. The outdoor pole 1 is reinforced by being fastened to the base 20, the rim 21a, and the eaves girder 21b with the fastener 3.

Next, FIG. 5 shows a two-story house.
It is a typical perspective view showing a part of example of a frame in the state where a reinforcement structure (claim 4) of the present invention was applied. In this reinforcing structure, in a frame structure of a wooden building, outdoor pillars 1a, 1a are provided along the outer wall outdoors at both ends of the end wall 80, and an outdoor beam 7c is provided so as to extend over the outdoor pillars 1a, 1a. The outdoor beam 7c and the outdoor columns 1a, 1a are joined together, and the joint (joint portion) thereof is reinforced with a reinforcing material 6c, and the outdoor columns 1a, 1a and the outdoor beam 7c are used as a framework. Is formed. In this case, the outdoor pillars 1a, 1
An intermediate outdoor beam 7d is also provided at the lower part (a part of the height direction) between "a" to further strengthen the horizontal strength.

It is needless to say that the reinforcing structure shown in FIGS. 1, 3, 4 and 5 can be combined. For example, a combination of the reinforcement structure of FIG. 1 and the reinforcement structure of FIG. 3 or FIG. 4 or FIG. 5, a combination of the reinforcement structure of FIG. 3 and the reinforcement structure of FIG. 4 or FIG. The combination, the combination of the reinforcing structures of FIGS. 1, 3 and 4 or 5, the combination of the reinforcing structures of FIGS. 3, 4 and 5, and the combination of the reinforcing structures of FIGS. 1, 3, 4, and 5 it can.

When the outdoor pillar 1 is provided so as to face the indoor pillar 2 as shown in FIG. 1, the outdoor pillar 1, 1 is not fastened to the indoor pillar 2, but the base 20 and the indoor beam (body) are fixed. Only the edge 21 is fastened with the fastener 3 to reinforce it and the indoor pillar 2
The joint (joint portion) between the upper beam 7 and the indoor column 2 mounted on the building is reinforced with a reinforcing material 6 to form a portal type structure with the outdoor columns 1, 1 and the indoor column 2 and the upper beam 7 as a frame. May be.

Next, in the installation of the outdoor pillar 1 (including the outdoor pillar 1a), particularly in an urban area, the outdoor pillar 1 (1a) is used in a narrow space.
In many cases, ease of construction is important.
That is, the gap in the upright direction of the fastener 3 is narrow, and
It is often necessary to rely on humans to transport the members, and it is convenient and safe in construction to reduce the unit weight as a single member and to assemble it on site. For this reason, it is preferable that the outdoor pillar 1 (1a) is not formed as an integral structure, but is formed as a divided structure in both cross section and length. However, since the bending rigidity with respect to the axis in the horizontal direction in FIG. 1 is important in the division, the cross-sectional performance should be made high in this axis direction.

FIGS. 6 to 8 show examples of typical outdoor pillars 1 (1a). The outdoor pillar 1 (1a) of FIG. 6 includes two outer pillar members 16, 16 and two inner pillar members 17, 17 divided in a cross-sectional direction, and a connecting bracket 18 is provided between the inner pillar members 17, 17. With the lower end portion of the inner column member 17 fitted inside the upper end portion of the outer column member 16, the connecting fitting 19 is passed between the outer column members 16, 16 and the bolt 19 a is used. The outer column member 16 and the inner column member 17 are fastened together.

The outdoor column 1 (1a) shown in FIG. 7 shows a joint structure of column members divided in a cross-sectional direction, which is a combination of large and small channel members, and the inner column member 11 is replaced with the outer column member 10.
The flanges are fitted to each other and joined together by bolts 12. In this case, the method of fixing the outer pillar member 10 to the indoor pillar 2 with the fastener 3 and then coupling the inner pillar member 11 to the outer pillar member 10 is easy as construction. In the case where the two column members are bolted to each other by the flange portions, the channel members having the same size may be overlapped and shifted by the thickness of the flange portions.

An outdoor pillar 1 (1a) shown in FIG. 8 shows a joint structure of four pillar members 13 divided in a sectional direction and a longitudinal direction. A connecting plate 14 is provided so as to straddle and is joined by bolts 15 via the connecting plate 14.

Regarding the outdoor column 1 (1a), it is important to reduce the weight both in construction and in reducing the inertial force of the seismic load, and it is preferable to manufacture metal parts as thin as possible from a metal plate. In particular, the outdoor pillar 1 (1a) is preferably made of metal in order to be lightweight, have high yield strength and high rigidity. As an important outdoor structure, the material of the pillar 1 (1a) is a plated material or a stainless steel, with due consideration given to rust prevention and weather resistance. It is preferable to use It is also possible to use a paint color that matches the outer wall of the part to be attached in consideration of the appearance. Note that the sectional shape and the longitudinal splitting / joining method of the outdoor pillar 1 (1a) are not limited to this example, and it is not always necessary to form a split structure, and a square pipe material or the like can be used. Of course. For joining the column members, tapping screws may be used in addition to bolt joining, and the number of bolts and the like are set so as to obtain sufficient joining strength.

Next, referring to FIG. 5, a description will be given of a reinforcing structure for horizontal strength in a direction plane which can be directly constructed with an outdoor pillar. In FIG. 5, the outdoor pillars 1 are located at the four corners of the building at both ends of the wall 80.
In this example, the outdoor pillars 1 are arranged along the eaves wall 81 of the building, and the outdoor pillars 1 are arranged in the eaves direction (the direction of the arrow A).
a, 1, 1, 1a are connected by a reinforcing material in a cross shape, and at the same time, the outdoor columns 1a, 1a arranged in the direction of the wife surface (arrow B direction) are connected by a reinforcing material in a cross shape, so that the outdoor columns are aligned. Horizontal rigidity in the plane (the direction of arrow A and the direction of arrow B) is provided. In this case, it is important that the outdoor pillars 1 and 1a are reinforced in a direction in which a plurality of the pillars are arranged side by side, and it is important to fasten them so as to form a triangle with the brace metal fittings 9a and the horizontal metal fittings 9b as reinforcing materials. preferable.
Although the horizontal bracket 9b is not always necessary,
In order to form a triangle, it is preferable to provide the horizontal fitting 9b. By the reinforcement using the metal fittings 9a and 9b, the rigidity of the vertical construction surface, that is, the rigidity as a bearing wall increases, so that the strength against a horizontal force such as an earthquake can be increased. The reinforcing structure using the metal fittings 9a and 9b may be provided in either the eaves direction (arrow A direction) or the end surface direction (arrow B direction), or as shown in FIG. It is preferable to reinforce both in the wife direction. In addition, it is needless to say that this reinforcing structure can be applied to the reinforcing structures of FIGS. 1, 3, 4, and 5.
