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 a hipped roof installed in a Japanese-style architectural house, the constituent members and ends of the ridge timber, east timber, and corner timber 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.

Also, only structural members with a predetermined thickness can be connected, and if the thickness of any one structural member is out of standard,
I can not use it.

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

Furthermore, although the above-mentioned hipped roof is convenient, it is not suitable for, for example, a square roof.

For this reason, a need has arisen for a connecting fitting that has a much simpler structure than connecting all the structural members, facilitates the connection between at least the timber bundles and the corner pieces, and can maintain sufficient connection strength.

The present invention was developed based on the above circumstances, and its purpose is to have a very simple structure, but to
The object of the present invention is to provide a connecting metal fitting that facilitates the connection of bundled timbers and corner timbers, improves work efficiency, and maintains sufficient strength.

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

1 in Fig. 1 is a sloped roof. . For example, it is a house having a hipped roof 2.

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 water collection 5 by appropriate means.

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

The connecting fitting 6 is as shown in FIG. 2.

That is, this is composed of a metal fitting main body 7 and a corner block receiving metal fitting 8.

The metal fitting main body 7 includes a water collection mounting part 9 formed to have approximately the same width as the water collection 5, and a support part 10 which is a support piece that is integrally bent along the upper edge of the water collection mounting part 9. Become.

The bending angle of this support portion 10 is matched to the slope of the corner bar 4, and the angle can be maintained by reinforcing ribs 11.

A pair of mounting holes 12° 12 are formed in the water collection mounting portion 9, and an insertion hole 13 is formed in the support portion 10.

The corner block bracket 8 is bent to have a substantially U-shaped cross section, and mounting holes 14 and 14 are formed facing each other in the vertical pieces 8a and 8a, and an insertion hole 15 is formed in the bottom part 8b. is drilled.

Then, this corner block receiving metal fitting 8 is placed on the support part 10, and after the through holes 13 and 15 are opposed to each other, the bolt 16 is inserted and the nut 17 is screwed and tightened.

Then, as shown in FIG. 3, the water collection mounting portion 9 of the metal fitting main body 7 is joined to the side surface of the water collection 5 and fixed by tightening with bolts and nuts inserted through the mounting holes 12 and 12.

Next, the end of the corner block 4 is fitted and supported in the substantially U-shaped corner block bracket 8, and the bolt 16 is inserted through the mounting hole 14.14.
Tighten and secure with nut 17.

At this time, if the mounting angle of the corner block bracket 8 and the expansion angle of the corner block 4 are different, once the bolts 16 and nuts 17 inserted through the insertion holes 13 and 15 are edged, and the corner block bracket 8 is attached to the corner block. Just tighten it after adjusting it to the expansion angle shown in step 4.

Therefore, it is convenient when it is necessary to store the corner block 4 with relief from the module core.

In this way, if the corner block 4.4 and the water collection 5 are connected using the connecting fitting 6, there is no need to perform complicated processing on each end for joining and connecting.

Moreover, the above-mentioned connections can be made by simply tightening bolts and nuts, and the mechanical strength of these connections is great.

In addition, the bending angle of the support part 10 and the mounting direction of the corner block bracket 8 can be set according to the slope and expansion angle of the corner blocks 4, 4, and since the reinforcing ribs 11 are provided, mechanical strength is sufficient. It is.

In addition, in FIG. 3, the case where the corner block 4 is connected to the water collection 5 from two directions has been explained, but the invention is not limited to this, and for example, as shown in FIG.
In the case where the corner block 4 is attached from one direction, the connection is possible even if the corner block 4 is inclined so as to intersect the upper end of the water collection 5.

Furthermore, it is possible to connect even when corner beams 4 are attached from four directions as in the case of a square roof.

As explained above, according to the present invention, the support piece is bent along the upper edge of the water collection attachment part attached to the side surface of the water collection part, and the reinforcing rib is formed over the water collection attachment part and the support piece. A connecting metal fitting is composed of a metal fitting main body formed by joining the edges, and a corner metal receiving metal fitting having a substantially U-shaped cross section that is placed on the upper surface of the support piece and supporting and fixing the corner metal piece, and the corner metal fitting is attached to one side of the support piece. Because it is rotatable, it is possible to reliably connect and fix the respective ends of the water collection and the corner timbers that make up the top of the pitched roof, even though the structure is extremely simple.

In addition, it is possible to temporarily hold and adjust the position of the corner corner, and it can be easily installed to match the expansion angle, improving work efficiency and eliminating the need for complicated machining on the ends of each of the above components. It is possible to provide an inexpensive connecting fitting that eliminates the risk of cross-sectional damage and has sufficient connection strength.
