Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting which can firmly bond a base and a foundation.

[0002]

[Problems to be Solved by the Invention] Not only is the construction cost of a wooden house lower than that of a reinforced concrete house,
The warmth of wood gives the residents a peace of mind and is preferred and widely used by many people. However, it is inferior to concrete houses in terms of strength, so measures against earthquakes, etc. are strongly desired.

Here, in order to increase the seismic resistance, it may be possible to use a special reinforcing tool or to adopt a complicated structure, but this causes an increase in construction cost and is not necessarily appropriate as a countermeasure.

The present invention has been made in view of the above problems, and provides a metal fitting which can be manufactured at a low cost and which can increase the seismic resistance without imposing an extra burden on the construction work. The task is to do.

[0005]

In order to solve the above-mentioned problems, the present invention is a joining fitting used in combination with an auxiliary fitting when joining strength is required, and is erected vertically. that a first portion, a second portion provided so as to be connected to one or both sides of the first part, the second part, the in use
An engaging portion for receiving the auxiliary metal fitting is provided, the auxiliary metal fitting is provided with an insertion opening for inserting the bolt member protruding from the foundation, and a part of the joining metal fitting is accommodated in a notch groove formed in the base. The base member and the foundation are integrated by inserting a bolt member into the insertion port, disposing the auxiliary metal fitting in the engaging portion, and tightening the nut member. Therefore, the structure of each metal fitting is simple,
Despite the ease of construction, the earthquake resistance of the house can be significantly increased.

In a preferred embodiment of the present invention, a notch groove formed in the base accommodates only the second portion of the joint fitting,
In this state, the auxiliary metal fitting is arranged at the engaging portion and the nut member is tightened to integrate the base and the foundation. In this case, the pillar provided with the cut groove is dropped from the top of the first portion and brought into contact with the surface of the foundation, and then the joining fitting and the pillar are fixed by a pin member or the like.

[0007] In another preferred embodiment of the present invention, the lower part of the second part and the first part of the joining metal fitting is accommodated in the notch groove formed in the base, and the auxiliary metal fitting is arranged in the engaging portion in this state. Then, the base and the foundation are integrated by tightening the nut member. In this case, the pillar provided with the cut groove is dropped from above the first portion and brought into contact with the upper surface of the base, and then the joining member and the pillar are fixed by a pin member or the like.

In any case, the present invention does not involve any special work, so that the construction work is not complicated. Particularly, in the embodiment in which the slide portion that smoothly opens in a substantially V shape is formed on the upper portion of the first portion, the work of positioning the column is easy. It is to be noted that a plurality of bases can be integrally fixed by using a joining metal fitting that is formed by connecting the main body portion and the L-shaped bent portion in a row and that has an engaging portion that receives the auxiliary metal fitting.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail based on the following examples. In the following description, specific numerical values are specified, but they are merely examples and are not intended to limit the present invention.

FIG. 1 is a front view showing a joining fitting 1A and an auxiliary fitting 2 according to the first embodiment. Joining metal fitting 1A
Is a substantially L-shaped plate member composed of a main body portion 3 standing upright in the vertical direction and a horizontal portion 4 continuous with the main body portion 3, and includes slide portions 5 and 6, an engaging portion 7, 10 mounting holes in total
1 to 8a4, 8b1 to 8b4, 8c1 and 8c2.

The main body 3 has a height of 225 mm and a width of 102 m.
It has a vertically long rectangular shape of about m, and at the center of its upper side, a slide portion 5 that smoothly spreads in a substantially V shape is formed.
The open end of the slide part 5 is formed in an arc shape, and when fixing the joining metal fitting 1A to the pillar, the pin member penetrating the pillar is attached to the bottom of the slide part 5 from the right side or the left side in the figure. It is slid down and positioned.

At the lower part of the slide portion 5, a diameter of 12.5 m
Four mounting holes 8a1 to 8a4 of m are formed. These mounting holes are arranged symmetrically with respect to a vertical line passing through the bottom of the slide portion 5, but the mounting holes 8a1
And mounting hole 8a2, and mounting hole 8a3 and mounting hole 8a4
They are arranged so that they are not located on the same vertical line. Therefore, even if a bolt or a pin is inserted through the bottom portion of the slide portion 5 or each of the mounting holes 8a1 to 8a4, the mounting holes are not aligned in the length direction of the column, and the column is not cracked or cracked in the event of an earthquake. Unlikely to occur.

Four mounting holes 8b1 to 8b4 having a diameter of 12.5 mm are formed in the lower portion of the main body portion 3 so as to be asymmetrical with respect to a vertical line passing through the bottom portion of the slide portion 5. That is, the mounting holes 8b1 and 8b2 are formed at positions 73 mm and 43 mm from the lower side, and the mounting holes 8b3 and 8b4 are formed at positions 58 mm and 28 mm from the lower side. Also, in the horizontal portion 4,
Two mounting holes 8c1 and 8c2 having a diameter of 12.5 mm are formed at positions of 50 mm and 20 mm from the lower side.

As described above, since the mounting holes 8b1-8b4 and the mounting holes 8c1, 8c2 are arranged so as not to be located on the same horizontal line, even if bolts or pins are inserted into the respective mounting holes 8b, 8c, the base Since the mounting holes are not aligned in the length direction of the, the base is not easily cracked or cracked in the event of an earthquake.

A slide portion 6 having a smooth and substantially rectangular shape is formed vertically above the mounting hole 8c2. The slide portion 6 has an open end formed in an arc shape,
For example, when fixing the base and the joining metal fitting 1A, the pin member penetrating the base can be slid down from the right side of the drawing to the bottom of the slide portion 6. Further, the engaging portion 7 is a rectangular groove having a length of 40 mm and a depth of 15 mm,
When used, the auxiliary metal fitting 2 will be received.
