Description

[Detailed description of the invention] This invention relates to a beam cover mounting structure.

In a building using the conventional framework panel construction method, as shown in Fig. 1, the second floor exterior wall panel 3 is attached to the upper surface of the lattice beam 1 which is bridged between the columns via the foundation metal fittings 2, and the lattice beam 1 Insert the upper part of the first floor exterior wall panel 5 into the groove 4 formed on the lower surface of the
A beam cover 6 is arranged on the outdoor side of the lattice beam 1 and attached between both outer wall panels 3 and 5. In this case, the lattice beam 1 is made by connecting a channel-shaped upper chord member 1a and a channel-shaped lower chord member 1b with a web 1c, and welding another channel steel 1d back to back to the lower surface of the channel-shaped lower chord member 1b. An outer wall panel fitting groove 4 is formed between the indoor flange 1e and the outdoor flange 1f of the channel steel 1d. Moreover, the beam cover 6 has a belt-like main body 6a.
The lower end edge is bent upward on the back side to form an inverted L-shaped piece 6b as shown in FIG. Furthermore, an L-shaped fixing piece 6d is formed on the upper part of the belt-shaped main body 6a. The beam cover 6 is installed by fitting the upper part of the first floor exterior wall panel 5 into the groove 4 of the lattice beam 1, and then inserting the rising piece 6c of the beam cover 6 between the outdoor flange 1f and the first floor exterior wall panel 5 from below. Insert and fix the L-shaped fixing piece 6d to the second floor exterior wall panel 3 with nails 7, and then insert a wedge 8 from the interior side between the interior surface 5b of the first floor exterior wall panel 5 and the interior side flange 1e of the channel steel 1d. By press-fitting,
A rising piece 6c of the beam cover 6 is formed by the outdoor side flange 1f of the channel steel 1d and the outdoor surface 5a of the first floor external wall panel 5.
Press and hold. Finally, a drainage board 9 is attached to the lower part of the outdoor surface of the exterior wall panel 3 to complete the construction.

However, since the rising piece 6c of the beam cover 6 is simply hooked onto the outdoor flange 1f, when rain and wind blow up from the outdoors 10 toward the lower part of the beam cover 6, the rainwater flows between the rising piece 6c and the outdoors. There was a problem in that it penetrated into the building by passing between the surfaces 5a.

Therefore, the purpose of this invention is to provide a beam cover mounting structure that has excellent rain protection performance.

An embodiment of this invention will be described with reference to FIGS. 3 to 5. That is, as shown in FIG. 3, in this beam cover mounting structure, a double-sided adhesive tape 12 is attached to the upper edge of one side of the sheet-like watertight material 11, and another double-sided adhesive tape 13 is attached to the lower edge of the other side.
As shown in FIG. A sheet-like watertight material 11 is stretched between the lower part of the beam cover 6 and the first floor outer wall panel 5 by pasting it to the front lower part of the main body 6a.

As shown in Fig. 5, the construction procedure is to adhere the sheet watertight material 11 to the first floor exterior wall panel 5 using adhesive tape 12, and then insert the first floor exterior wall panel 5 into the groove 4 of the lattice beam 1 from below. , hook the rising piece 6c of the beam cover 6 onto the outdoor flange 1f of the lattice beam 1, and attach the upper part of the beam cover 6 to the second floor exterior wall panel 3.
(see Fig. 1), and by press-fitting the wedge 8 between the indoor surface 5b of the first-floor external wall panel 5 and the indoor-side flange 1e of the lattice beam 1, the outdoor surface 5a of the first-floor external wall panel 5 and The outdoor side flange 1f of the lattice beam 1 sandwiches the rising piece 6c of the beam cover 6 and the upper edge of the sheet watertight material 11, and as shown in FIG. It is folded back and its lower edge is adhered to the front lower part of the beam cover 6 using an adhesive tape 13. Since the other configurations and construction procedures are the same as those of the conventional example, the same parts are given the same reference numerals and the explanation thereof will be omitted.

In this way, the upper edge of the sheet watertight material 11 was adhered to the first floor exterior wall panel 5 with the adhesive tape 12, and the lower edge of the sheet watertight material 11 was adhered to the lower front of the beam cover 6 with the adhesive tape 13. This sheet-like watertight material 11 can prevent rainwater from entering the building from between the beam cover 6 and the first-floor exterior wall panel 5, and can improve rain-shedding performance. In this case, sheet watertight material 1
Since one side of the sheet watertight material 11 is glued to the first floor exterior wall panel 5 and the other side is glued to the front lower part of the beam cover 6, the work becomes complicated when applying adhesive to both sides of the sheet watertight material 11. In contrast, in this embodiment, since double-sided adhesive tapes 12 and 13 were attached to both sides of the sheet-like watertight material 11, the release paper of the adhesive tape 12 was peeled off and the adhesive tape 12 was attached to the outdoor surface 5a of the first floor exterior wall panel 5. The upper edge of the sheet watertight material 11 can be adhered to the first floor exterior wall panel 5 by simply pressing it from the top end surface 5c to the upper end surface 5c. Also, after attaching the first floor exterior wall panel 5 and the beam cover 6 to the lattice beam 4, the adhesive tape 13 The lower edge of the sheet-like watertight material 11 can be adhered to the beam cover 6 by simply peeling off the release paper and pressing the adhesive tape 13 against the front lower part of the beam cover 6. In this way, the sheet-like watertight material 11 can be attached extremely easily. can be installed.

Of course, the sheet-like watertight material 11 may be attached using an adhesive instead of the double-sided adhesive tapes 12 and 13.

As described above, the beam cover mounting structure of this invention consists of a beam in which an outdoor flange and an indoor flange are protruded from both sides of the lower surface of the beam, and a panel fitting groove is formed between the two flanges, and the upper part is attached to the panel. The first-floor exterior wall panel fitted into the fitting groove, the second-floor exterior wall panel attached to the top of the beam, and the lower edge of the strip-shaped body folded back to the back side to form a rising piece, the strip-shaped body is attached to the beam. a beam cover which is arranged on the outdoor side of the main body, and the rising piece is inserted between the outdoor surface of the first floor external wall panel and the outdoor flange to fix the upper end edge of the strip body to the second floor external wall panel, and one end of the beam cover; a sheet-like watertight material whose edge is adhered to the upper edge of the outdoor surface of the first floor exterior wall panel, folded back at the center and whose other edge is adhered to the lower edge of the front surface of the band-shaped main body of the beam cover; and the first floor exterior wall panel. The rising piece of the beam cover and one end edge of the sheet-like watertight material are press-fitted between the indoor surface of the first floor exterior wall panel and the outdoor flange, thereby clamping the rising piece of the beam cover and one end edge of the sheet watertight material. Because it is equipped with a wedge, it has the effect of having excellent rain protection performance.
