Abstract

PROBLEM TO BE SOLVED: To alleviate shaking due to an earthquake or the like, and ensure safety by providing a damper made of an outer cylinder and an inner cylinder laid so as to come in slidable contact with each other, and a coil spring housed in the outer cylinder at the end of the bracing or the horizontal brace of a wooden framework. SOLUTION: A damper 6 is formed out of an inner cylinder and an outer cylinder laid so as to come in slidable contact with each other, and a coil spring housed in the outer cylinder so as to be compressible with the inner cylinder. Also, box type hardware coupled to a brace 5 or a wooden end for a horizontal brace is integrated with the end of outer cylinder, and the outer cylinder is secured to the end of the brace 5 with a screw or a nail via the box type hardware. Then, the brace 5 is jointed to a beam 4 or the like via the damper 6, and made compatible,, even when the mounting angle of the brace 5 changes, depending on length between columns 3. As a result, the damper 6 is made to have nothing to do with a small vibration, but functions through the compression of the coil spring, upon exposure to a large external force such as an earthquake. Thus, vibration energy is absorbed and shaking can be thereby restrained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden frame building.

[0002]

2. Description of the Related Art In Japan, many wooden single-family homes have been constructed as houses, and most of them use the traditional wooden frame construction method. This wooden frame construction method is a method of assembling a frame with timber columns, beams, bases, braces, fires, and the like.

[0003]

However, a single-family house constructed by the wooden frame construction method may be greatly shaken and collapsed during a large earthquake or large typhoon, which may endanger human life. In order to reduce these damages, a device that absorbs vibration is attached to the wooden frame to reduce the shaking of the building and collapse the building.
You can prevent destruction. Further, not only can furniture be prevented from falling due to shaking of the building and articles can be prevented from falling, but damage can be reduced and a passage can be secured during evacuation. Especially for detached houses,
Since children and infants also live in these areas, these vulnerable people cannot escape from their homes or escape when they are in a disaster such as an earthquake or typhoon.

Further, a wooden building is vulnerable to fire, and a heating device such as a stove may fall down and be burned by an earthquake, a sway of wind or the like.

It is an object of the present invention to provide a vibration-absorbing wooden building which eliminates the disadvantages of the conventional example and can reduce the shaking caused by an earthquake, a typhoon, etc. to improve the safety.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a structure in which a damper made of a coil spring is provided at the end of the braces or the braces and the striking of the wooden frame, and the dampers are mutually connected. It consists of a sliding outer cylinder, an inner cylinder, and a coil spring housed in the outer cylinder.A box metal fitting is fitted at the end of the outer cylinder to fit a wood line for striations and fires. The idea is to wear it.

According to the first and second aspects of the present invention, the damper does not work at the time of a small vibration, but when a large external force is applied due to an earthquake or a typhoon, the coil spring is pressed and the damper acts. However, since it absorbs the vibration energy, it can be made to have no shaking.

Further, since the damper is arranged as a part of the striation or the fire, the damper can be easily incorporated in the frame without taking up any space.

According to the third aspect of the present invention, it is possible to provide a damper having a simple structure capable of effectively exhibiting the action of the coil spring in addition to the above action. Further, the damper is attached to a beam or the like. Since the angle can be changed at the location where the metal object is mounted on the shaft, it is possible to cope with the mounting angle, such as a streak on the beam, which differs depending on the length between the columns.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view of a main part showing one embodiment of a vibration absorbing wooden building of the present invention, FIG. 2 is a vertical sectional front view of a damper, FIG. 3 is a vertical sectional side view of the same, in which 1 is a foundation and 2 is above it. The base, 3 is a pillar, 4 is a beam, and 5 is a bracing, which is the case of a so-called wooden frame.

The braces 5 are arranged diagonally between the beams or the beams 4 and the base 2, but in the present invention, a damper 6 by a coil spring is arranged at the end of the braces 5 of the wooden frame. did.

The damper 6 comprises a metal pipe, an outer cylinder 7 and an inner cylinder 8 which are slidably in contact with each other, and a coil spring 9 is housed in the outer cylinder 7 so as to be pressed by the inner cylinder 8. Even if this coil spring 9 is fixed to the outer cylinder 7 side,
It may be fixed to the inner cylinder 8 side.

Further, a box metal fitting 10 which is fitted to the end of the outer cylinder 7 and which is fitted to the end of the wood for striation and fire is integrally provided.
Allows screws 11 or nails to be attached to the end of the braces 5 etc. via 10.

On the other hand, at the end of the inner cylinder 8, a pin 12 is passed inside, and a rotary plate 13a through which the pin 12 penetrates is vertically installed.
A stopper 13 made of 13b was attached to the shaft. The joining plate 13b is attached to the wood such as the beam 4 and fixed with screws 11 or the like. Inner cylinder 8 is a rotating plate
A slit 15 is provided so that 13a can rotate.

In this way, the braces 5 are connected to the beams 4 and the like via the dampers 6, but since the angle can be changed at the shaft attachment point of the metal stopper 13, the mounting angle α of the braces 5 can be changed as shown in FIG. It is possible to deal with the difference between the pillars 3 depending on the length. The damper 6 is arranged at one end or both ends of the bracing 5.

5 and 6 are elevation views of the wooden frame,
As a general rule, the number of left slanted streaks 5 and the number of right slanted streaks 5 are the same, and in the same building, the damper 6 is attached to either the upper part or the lower part of the strut 5.

There are three types of braces 5 attached to one span: left tilt, right tilt, and left tilt / right tilt cross.

FIG. 7 is a plan view (floor plan, hut plan) of a wooden framework showing another embodiment of the present invention.
The damper 6 may be arranged at the end of 14. In this case, the angle at which the flints 14 are attached is 45 °, and the number of flints 14 at the right 45 ° and the left 45 ° is the same in principle in both the short span and the plural spans.
