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 and 4. That is, as shown in FIG. 3, this beam cover mounting structure is constructed by bending a band-shaped metal plate in a substantially C-shape in the width direction to form the main body 11a, and folding one side edge of the main body 11a into a V-shape. An elastic draining plate 11 with a watertight material mounting portion 11b formed thereon is prepared, and the elastic draining plate 11 is compressed in the width direction and inserted into the corner recess 12 of the inverted L-shaped piece 6b from below the beam cover 6. By elastically returning, both sides of the draining board 11 are brought into elastic pressure contact with the vertical sides of the inverted L-shaped piece 6b and the outdoor surface 5a of the first floor exterior wall panel 5, as shown in FIG. A watertight material mounting portion 11b is provided between the outdoor surface 5a of the first floor exterior wall panel 5.
Fill the watertight material 13 from below using the Since the other configurations 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, since the drain plate 11 and the watertight material 13 are arranged between the vertical side of the inverted L-shaped piece 6b of the beam cover 6 and the outdoor surface 5a of the first floor exterior wall panel 5, the inside corner recess 12
Intrusion of rainwater into the interior can be prevented, and therefore rainwater can be prevented from rising between the rising piece 6c of the beam cover 6 and the outdoor surface 5a of the first floor outer wall panel 5, and the rain protection performance can be improved. Furthermore, the draining plate 11 can be attached very easily by inserting it into the corner recess 12 in a state where it is elastically compressed in the width direction and elastically returning it.

Another embodiment of this invention is shown in FIG. That is, as shown in the figure, this beam cover mounting structure is such that a watertight material 13' such as rubber is fixed in advance to the watertight material attachment part 11b' of the draining plate 11', and the watertight material 13' is fixed in advance to the watertight material attachment part 11b' of the draining plate 11'. When installing the watertight material 13' into the recess 12, the watertight material 13' is also attached to the outdoor surface 5a of the first floor exterior wall panel 5.
make it come into contact with the Since the other configurations are the same as those of the above embodiment, the same parts are given the same or corresponding symbols and the explanation thereof will be omitted. According to this beam cover mounting structure, in addition to achieving the same effect as in the above embodiment, since the watertight material 13' is fixed to the draining plate 11' in advance, the watertight material 13' is attached at the same time as the draining plate 11'. The installation can be completed, and the construction can be simplified compared to the above embodiment.

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 1st floor exterior wall panel fitted into the fitting groove, the 2nd floor exterior wall panel attached to the top of the beam, and an inverted L-shaped piece connected to the back side of the lower edge of the strip body, and a rising piece at the tip of the lateral side. The projecting strip body is placed on the outdoor side of the beam, and the rising piece is inserted between the outdoor surface of the first floor exterior wall panel and the outdoor flange, and the upper end edge of the strip body is placed on the second floor exterior wall. The beam cover fixed to the panel is press-fitted between the indoor surface of the first floor external wall panel and the indoor flange, thereby press-fitting the rising piece of the beam cover between the outdoor surface of the first floor external wall panel and the outdoor flange. In the beam cover mounting structure equipped with wedges to be sandwiched, both side edges of the elastic drain plate formed by bending the strip plate in the width direction,
A watertight material is attached to the vertical side of the inverted L-shaped piece and the outdoor surface of the first floor exterior wall panel, respectively, and a watertight material is provided at the joint between the elastic drainage board and the outdoor surface of the first floor exterior wall panel, which improves rain protection performance. It has an excellent effect.
