Description

[Detailed explanation of the idea] This invention relates to a beam cover attachment device.

In places where there is no distance between neighboring buildings, such as on a narrow site, there is a problem in that the beam cover cannot be attached to the outdoor side of the beam because there is little effective working space on the outdoor side.

Therefore, an object of this invention is to provide a beam cover mounting device that allows the beam cover to be attached only by working from the indoor side.

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

That is, this beam cover attachment device is applied to a prefabricated house using the frame construction method, and first, lattice beams 1 are erected between pillars erected on a cloth foundation (not shown).

This lattice beam 1 is constructed by connecting a grooved upper chord member 2 and a grooved lower chord member 3 with a web 4, and by welding a grooved crown portion 5 to the grooved lower chord member 3.

A second floor wall panel support 6 is fixed to the upper surface of this lattice beam 1.

The second floor wall panel bracket 6 is an L-shaped piece in cross section, with a projecting piece 6b horizontally raised to the outdoor side at approximately the center height of the vertical piece 6a, and the vertical piece 6a is at the center of the upper surface of the upper chord member 2. The horizontal piece 6C is screwed onto the upper chord member 2 so as to be located at the upper chord member 2, and a fitting recess 7 is formed between the protruding piece 6b and the upper surface of the upper chord member 2.

Next, the beam cover support fitting 8 is attached to the lower chord member 3.

This beam cover support fitting 8 is made by folding back the tip of the vertical piece of the L-shaped piece 8a to form a hook 8b.
A locking piece 8C is formed by bending the tip of the horizontal piece a upward, and the hook 8b is attached to the outdoor side flange 3a of the lower chord member 3.
and place it on the outdoor side of the lower chord material 3.

After that, the beam cover 9 is attached to the outdoor side of the lattice beam 1.

This beam cover 9 has upper and lower base materials 9b and 9C fixed to the two lower ends of the surface plate 9a, and a retaining groove 9d is formed on the outdoor side of the lower surface of the lower base material 9C.

The installation procedure is to place the lower base material 9C on the horizontal piece of the beam cover support fitting 8, fit the locking piece 8C into the engagement groove 9d, fit the upper base material 9b into the fitting recess 7, A nail 10 is driven into the vertical piece 6a of the second floor wall panel holder 6 from the indoor side to dry it out.

Next, the first floor outdoor panel 11 is placed on the grooved crown 5 of the lattice beam 1.
Insert it into the upper end of the holder and secure it with the wedge 12.

After that, the drain plate 13 is attached to the upper part of the beam cover 9.

This drain plate 13 has an inverted V-shaped locking piece 13 at its upper end.
a to the upper end of the vertical piece 6a of the second floor wall panel holder 6, while tilting the center piece 13b downward toward the outdoor side, the lower piece 13C is fitted along the upper edge of the outdoor surface of the surface plate 9a of the beam cover 9. let

Finally, attach the second floor exterior wall panel 14 to the second floor exterior wall panel holder 6.
is installed on the vertical piece 6a.

In this case, the second floor exterior wall panel 14 has a groove 14 on its lower end surface.
a, and the inverted V-shaped locking piece 1 of the drain plate 13 is located in the groove 14a.
3a, the upper end of the vertical piece 6a of the second floor outer wall panel holder 6 is fitted.

As a result of this structure, the beam cover support fitting 8 can be hooked onto the flange 3a of the lower chord member 3 from the indoor side,
Also, from the indoor side, the fitting groove 9d of the beam cover 9 is engaged with the locking piece 8C of the beam cover support fitting 8, and the upper base material 9
b can be fitted into the fitting recess 7 and fixed by nailing, which means that the beam cover 9 can be easily installed by working only from the indoor side, even in places where there is no distance between adjacent buildings such as on a narrow site. Construction is now possible.

In addition, a draining board 13 is installed between the second floor exterior wall panel 14 and the beam cover 9.
It also has excellent rain protection performance.

As described above, the beam cover mounting device of this invention has a flange erected at a predetermined position with a flange erected on the outdoor edge of the upper surface of the lower chord, and a beam erected approximately at the center of the upper surface of the upper chord of the beam. an upper floor wall panel holder having a fitting recess formed between a projecting piece horizontally protruding from its outdoor surface and the upper surface of the upper chord member; and a vertically extending approximately L-shaped piece having a horizontal piece projecting forward. One end is bent back to form a hook, and the end of the horizontal end is bent upward to form a locking piece.The hook is hooked onto the bottom chord flange of the beam and placed on the outside side of the bottom chord. The beam cover support fittings are fixed to the upper and lower ends of the back surface of the top plate, and a fitting groove is formed on the bottom surface of the bottom plate parallel to the top plate. Since the beam cover is provided with the upper base material fitted into the fitting recess by engaging the locking piece of the cover support fitting, there is an effect that the beam cover can be attached only by working from the indoor side.
