Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting fitting used at the top of a pitched roof such as a hipped roof.

For example, in the hipped roof of a Japanese-style architectural house,
The ends of constituent members such as ridge timbers, bundle timbers and corner timbers face the top.

When connecting the ends of these components,
In the case of a wooden house, processing such as mortise processing must be performed on each end, which is very time-consuming and troublesome, and also tends to cause cross-sectional defects, resulting in a decrease in strength.

Furthermore, in the case of a structure other than wood, the joints of the above-mentioned constituent members are complicated, resulting in inconveniences such as poor assembly work efficiency.

Therefore, recently, metal fittings for attaching and integrally connecting all the constituent members have been developed and put into practical use.

If this type of metal fitting is used, there is no need to process the ends of the component parts, and there are advantages such as improved connection strength.

However, since a large number of component members are connected, the structure of the metal fitting itself is complicated and it takes time and effort to manufacture.

Further, only constituent members having a predetermined thickness can be connected, and if the thickness of any one constituent member is outside the standard, it cannot be used.

At the same time, even if the combined slope of the constituent members is outside the standard, it cannot be used.

Furthermore, while the above-mentioned hipped roof is convenient, it is unsuitable for square roofs, for example.

For this reason, a need has arisen for a connecting fitting that has a much simpler structure than connecting all the constituent members, facilitates the connection between at least the east wood and the corner wood, and maintains sufficient connection strength.

The present invention was developed in consideration of the above circumstances, and its purpose is to have a very simple structure, but to
It is an object of the present invention to provide a connecting metal fitting that can extremely easily connect bundled timbers and corner timbers, improve work efficiency, and maintain sufficient strength.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 in FIG. 1 indicates a house having a pitched roof, for example, a hipped roof 2. In FIG.

The top A of the hipped roof 2 is made up of a ridgepole 3 forming a column, corner beams 4, 4 forming a corner ridge, and a bundle 5 installed at right angles to the ridgepole 3, with their respective ends facing each other. .

The corner pieces 4, 4 and the bundle pieces 5 are connected to a connecting fitting 6, which will be described later.
are integrally connected.

The purlin 3 is connected to the corner timbers 4, 4 and the bundle timbers 5 by appropriate means.

Note that the ridgepole 3, the corner timbers 4, 4, and the bundle timbers 5 are made of wood.

The connecting fitting 6 is shown in FIGS. 2 and 3.

In other words, this includes a metal fitting main body 7, a pair of corner block brackets 8,
It is constructed from 8.

The metal fitting main body 7 includes a bundle mounting portion 9 formed to have approximately the same width as the width of the bundle 5, and support portions 10 along both side edges of the bundle mounting portion 9.
10 are integrally expanded and provided.

A mounting hole 11.11 is bored in the bundle mounting portion 9.

The expansion angle of the support parts 10, 10 is adjusted to the expansion angle of the corner blocks 4, 4.

Moreover, the upper edge of the support part 10.10 is inclined in accordance with the slope of the corner pieces 4, 4.

The edges of the bundle attachment part 9 and the support part 10.10 are joined together, and a reinforcing rib 12 is provided by means of welding, for example, so that the expansion angle of the support part 10.10 can be maintained. There is.

The corner block bracket 8 is bent to have a substantially U-shaped cross section, and the support bracket 1 is bent to have an inverted cross section along the bottom.
3 is fixed by means such as welding.

Then, the vertical piece of the support metal fitting 13 is tightly attached to the side surface of the support part 10, and the horizontal piece of the support metal fitting 13 is placed on the upper edge of the support part 10 and fixed to each other by means such as welding.

Therefore, the corner block bracket 8 is placed on the support portion 10.

Incidentally, mounting holes 14 and 14 are formed in the corner block bracket 8 so as to face each other.

Then, the bundle mounting portion 9 of the metal fitting main body 7 is joined to the side surface of the bundle 5, and the bolts and nuts inserted through the mounting holes 11 and 11 are tightened and fixed.

Next, the end of the corner block 4 is fitted and supported by the substantially U-shaped corner block receiving bracket 8, and is fixed by tightening bolts and nuts inserted through the mounting holes 14, 14.

The ends of the corner beams 4, 4 are processed so that they have surfaces that connect with each other and also have surfaces that connect with the purlin 3 and the bundling timbers 5.

If the corner pieces 4.4 and the bundle pieces 5 are connected in this way using the connecting fittings 6, there is no need to perform complicated processing on the respective ends for joining and connection.

Furthermore, the above connection can be made by simply tightening bolts and nuts, and the mechanical connection strength of these connections is high.

Moreover, the corner block bracket 8 is connected to the support part 10 via the support bracket 13.
The stability is good because the support part 10,
The expansion angle of 10 and the inclination of the upper end edge can be set in advance according to the expansion angle and slope of the corner blocks 4, 4, and since the reinforcing ribs 12 are provided, the mechanical strength is sufficient.

Furthermore, the connecting fittings 6 are not only used for hipped roofs 2; for example, even in the case of the corner ridge top of a square roof where the corner pieces 4 are attached to the bundle pieces 5 from four directions, Connection is possible by using two connecting fittings 6.

Further, in the above embodiment, the corner block bracket 8 is connected to the support bracket 13.
Although it is arranged on the metal fitting main body 7 via the corner block receiving metal fitting 8, the present invention is not limited to this. For example, as shown in FIG.

(Note that the same parts as in the above embodiment are given the same numbers and the explanation will be omitted.

) As explained above, according to the present invention, the support parts are expanded on both sides of the bundle mounting part attached to the side of the bundle, and the edges of the reinforcing ribs extend across the bundle mounting part and both supporting parts. A connecting fitting is constructed from a fitting main body formed by joining the two pieces together, and a corner piece receiving fitting which is placed on the upper edge of the support part and has a substantially U-shaped cross section for supporting and fixing the corner piece, and the bundle constitutes the top of the pitched roof. This is to fix and connect the ends of a tree and two corner pieces.

Therefore, although it has a very simple structure, it is possible to temporarily hold and adjust the position of the corner pieces, and the bundle pieces and corner pieces can be reliably connected, improving work efficiency, and it is possible to perform complex processing on the ends of each member. It is possible to provide an inexpensive connecting fitting that eliminates the need for cross-sectional defects and has sufficient connection strength.
