Description

[Detailed Description of the Invention] The present invention relates to an outer wall structure, and the object of the present invention is to open and close the movable circumferential edge in summer by opening and closing the movable circumferential edge by sensing the temperature of a bimetal. The air in the gap between the exterior material and the wall escapes upward, improving the heat dissipation effect.In winter, by closing the movable edges, the air in the gap does not escape, improving the heat retention effect, and improving the appearance. The goal is to provide an unsightly exterior wall structure.

The present invention will be explained in detail below using examples.

Reference numeral 1 denotes a wall surface on the first or second floor finished with mortar or the like, and a fixing frame 2 as shown in FIGS. 4 and 6 is attached to the vertical direction of the wall surface 1 using fixing fittings 3.

As shown in FIG. 4, the outer wall material 4 is formed by mutually engaging and connecting the upper and lower engaging portions γ and the engaged portions 8 of a plurality of materials 6 having a stepped portion 5 in the center. A mounting piece 9 provided at the upper end of the upper material 6 is attached by screwing a screw 19 through a long hole 10 of the mounting piece 9 into a tapping hole 11 of the fixed frame 2.

An opening 14 communicating with the gap 13 is provided between the upper end of the exterior material 4 and the eaves 12, and a movable surrounding edge 15 that can be opened and closed freely is provided in the opening.

This movable surrounding edge 15 has a fixed piece 15a with a fixed hole 16 and a movable piece 15b screwed onto the hinge part 18, and the fixed piece 15a
and a movable piece 15b are connected to a bimetal 1γ, and a fixed piece 15a is fixed to the eave ceiling 12.

The movable circumferential edge 15 may be provided over the entire length of the upper end of the exterior material 4, or may be provided partially and the remaining circumferential edge may be a fixed circumferential edge.

However, in the summer, the radius of curvature of the bimetal 110 increases due to the high temperature, and the movable piece 15b of the movable circumferential edge 15 opens, allowing air to escape from the gap 13 as shown by the arrow in FIG. 2a and radiating heat.

In addition, in winter, due to low flooding, the radius of curvature of the bimetal 110 becomes small, and as shown in FIG.
The air in the gap 13 is closed and the air in the gap 13 is kept warm.

As described above, the present invention involves attaching an exterior material to the outer surface of a wall through a gap, and operating the opening and closing operation using bimetal temperature sensing in an opening that communicates with the gap provided between the upper end of the exterior material and the eaves. Since the movable surrounding edge is installed, the movable surrounding edge is automatically opened and closed by bimetal depending on the outside temperature, and when the movable surrounding edge is opened in the summer, the gap between the exterior material and the wall surface is reduced. The air in the gaps escapes upwards, improving the heat dissipation effect, and in winter, by closing the movable edges, the air in the gaps does not escape, improving the protection effect, allowing for comfortable living in both summer and winter. Moreover, since the movable surrounding edge is installed in the opening between the upper end of the exterior material and the soffit, it is difficult to see from the outside and does not make the appearance unattractive. Even though a movable surrounding edge is attached to the opening, which is located at a high place, the opening and closing operation is performed using a metal bar, so there is no breakdown and there is no need for repairs, making maintenance easy.
