Description

[Detailed description of the invention] This invention relates to a member joining structure that can be used for joining building members.

In the conventional framework structure, as shown in Fig. 1, a lattice casing 1 is bridged between the central parts of through columns (not shown), and a second-floor wall panel is attached to the upper part of the lattice casing 1 on the outdoor side. By attaching the first floor wall panel to the lower part of the outside, and further arranging a cover (not shown) between the second floor wall panel and the first floor wall panel and connecting this cover to the outdoor side of the lattice 1, this The cover moderates Lattice 1.

In this case, the lattice wire 1 connects the grooved upper chord 1a and the grooved lower chord 1b with the web material 1c, and also connects the grooved lower chord 1a to the grooved lower chord 1b.
Another channel member 1d is welded to the lower surface of b.

To attach the lattice cover 1 to the lattice 1, prepare the wooden beam cover base material 2 whose upper and lower ends 2a and 2b are finished narrowly, and attach the upper and lower ends 2a and 2b to the top chord material 1 of the lattice 1.
After driving into the grooves a and 1b, the roe cover is placed along the central convex portion 2c of the roe cover base material 2 and fixed with a nail.

However, since the lattice casing 1 is made of metal and the casing cover base material 2 is made of wood, when the upper and lower ends 2a and 2b of the lattice cover base material 2 are driven into the grooves of the lattice casing 1,
Due to wear and contraction of the upper and lower ends 2a and 2b, a gap 3 is created between the upper chord material 1a and the lower chord material 1b as shown in FIG. The problem was that it could not be joined.

Note that this problem similarly occurs when a wooden connecting member is generally driven into a groove of a metal connecting member.

Therefore, an object of this invention is to provide a member joining structure that can firmly and reliably connect wooden members to be connected into grooves of metal connecting members.

An embodiment of this invention will be described with reference to FIGS. 3 to 5.

That is, this member joining structure is characterized in that the casing cover base material 2 is attached to the lattice casing 1 using the U-shaped metal fitting 4 shown in FIGS. 3 and 4.

This U-shaped metal fitting 4 has both side pieces 4a partially cut and raised inward to form claws 4b, and both side pieces 4a slightly expanded outward to form an angle with the center piece 4c. Set θ slightly larger than 90 degrees.

In this case, the distance between the tips of the both side pieces 4b is set to be slightly larger than the groove width of the upper chord member 1a.

Then, with the U-shaped metal fitting 4 attached to the upper end 2a of the lattice cover base material 2, the tile cover base material 2 is inclinedly arranged inside the lattice 1, as shown by the imaginary line in FIG. by inserting it into the groove of the lower chord material 1b, raising the cover base material 2, and driving its upper end 2a together with the U-shaped metal fitting 4 into the groove of the upper chord material 1a in a wedge shape from the direction of arrow A. The lattice cover base material 2 is connected to the lattice 1 as shown by the solid line.

In this case, by driving the U-shaped metal fitting 4 into the groove of the upper chord member 1a, both side pieces 4a of the U-shaped metal fitting 4 are pushed inward by both side surfaces of the groove of the upper chord member 1a, and the claws 4b are bent at the upper end 2a. dig into it.

In this way, the claw 4b of the U-shaped metal fitting 4
In addition, since both side pieces 4b of the U-shaped metal fitting 4 are pressed against the inner surface of the groove of the upper chord member 1a, the casing cover base material 2 can be firmly and reliably connected to the lattice casing 1.

This invention can be applied not only to the connection between the lattice cover base material 2 and the lattice lattice 1, but also to the connection of wooden members to be connected into the grooves of metal connecting members.

As described above, the member joining structure of this invention has claws protruding from the inner surfaces of both sides of the members to be connected and the members to be connected in a state where both sides of the members are slightly expanded outward. By press-fitting the U-shaped metal fitting in a wedge shape into the groove of the U-shaped metal fitting attached to the end portion, both sides of the U-shaped metal fitting are bent inward, and the claw is attached to the cover. Since the connecting member is provided with a connecting member cut into the connecting member, the wooden member to be connected can be firmly and reliably connected into the groove of the metal connecting member.
