Description

[Detailed Description of the Invention] The present invention relates to a ridgepole fixing device for connecting and fixing a ridgepole made of wood and a metal support member, for example, a truss beam consisting of at least an upper flange and a web.

Recently, even in general wooden houses, it has become common to partially use steel frames to increase strength and improve durability. In particular, the above-mentioned steel frame materials are often used as support members for supporting purlins, so-called truss beams. These truss beams and purlins must be connected and fixed by some means.

For this reason, in the past, as shown in Fig. 1, the purlin c was placed on the top flange of the truss beam a through the packing b.
The ridgepole c and the truss beam a are wrapped around each other with a thick wire d to secure them to each other.

However, this type of means is not only time-consuming, but also difficult to align, and is not strong enough.

The present invention was developed based on the above circumstances, and its purpose is to provide a purlin fixing device that has a very simple structure and can be easily and reliably installed. be.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. That is, this is a metal plate made by, for example, sheet metal processing. At the top thereof, there is provided a gripping and fixing part 1 which is bent into a substantially U-shape so that the upper part is open. The distance between the two vertical pieces 2, 2 constituting the gripping and fixing part 1 is such that the purlin S can be fitted thereinto, and a plurality of nail holes 3 are formed in each of them. In addition, the gripping fixing part 1
The receiving piece 4 between the vertical pieces 2, 2 constituting the frame has connecting pieces 6, 6 integrally folded at approximately the center of both side edges thereof, which connect the gripping fixing part 1 and the engaging parts 5, 5, which will be described later. A song is formed. In other words, the connecting pieces 6, 6 are the receiving pieces 4.
The engaging portion 5 is bent vertically downward from the upper mating piece 7 extending horizontally outside the receiving piece 4.
The upper fitting piece 7 is composed of a horizontal fitting piece 8 which is bent vertically downward along one side edge of the upper fitting piece 7, and a hooking piece 9 which is bent along the other side edge. The upper fitting piece 7 and the side fitting piece 8 have substantially the same dimensions as the upper surface flange 10a and the web 10b of the truss beam 10, which is a supporting member and is made of a steel frame material. The hook piece 9 has a dimension that is only slightly longer than the wall thickness of the upper surface flange 10a of the truss beam 10, and an uneven portion 11 formed by, for example, press working is provided inside the area. Note that fixing holes 12, 12 are bored in the side pieces 8, 8.

Thus, the truss beam 10 is provided at a predetermined position.
Next, this device is attached to the truss beam 10. That is, as shown by the two-dot chain line in FIG. 3, the hook piece 9 is hooked onto the edge of the upper flange 10a of the truss beam 10, and then rotated. The upper fitting piece 7 is in close contact with the truss beam 10, and the side fitting piece 8 is in close contact with the upper surface flange 10a and the web 10b, respectively. Since the hooking piece 9 is provided with the uneven portion 11, the hooking portion 5 is not easily removed from the truss beam 10. A bolt 13a is inserted into the fixing hole 12 of the side piece 8 and a through hole (not shown) made in the web 10b, and a nut 13b is screwed into the bolt 13a and tightened, thereby fixing them to each other using this fixing tool. That is, one end of the engaging portion 5 is engaged with the upper surface flange 10a, and the other end is fixed to the web 10b. Then, the purlin S is fitted into the gripping and fixing part 1. That is, the purlin S is placed oppositely between the vertical pieces 2, 2, and then placed on the receiving piece 4. Nail holes 3 drilled in the vertical pieces 2, 2
Insert the nail 14 from ... and drive it into the ridgepole S.
can be connected and fixed to the truss beam 10.

As explained above, according to the present invention, the hook piece of the hook part is hooked to the top flange of the support member, the top piece of the hook part is brought into close contact with the top flange, and the side piece is attached to the web of the support member. A gripping and fixing part is connected to the upper part of the engaging part via a connecting piece to grip and fix the ridgepole. Therefore, the fixing device can be attached from the side of the support member,
Alternatively, it is possible to attach the ridgepole to the fixing device and then hook it to the support member, making it very easy to connect and fix the ridgepole and the support member, improving workability and improving reliability. It has effects such as obtaining.
