Description

[Detailed Description of the Invention] The present invention relates to improvement of the projecting corner structure of buildings and storerooms. The purpose is to prevent deformation of accessories at the protruding corners,
The objective is to securely fix external wall materials, improve the appearance of protruding corners, and reduce rust caused by fixed parts.

Conventionally, the projecting corner structure of this type of building has been constructed as shown in Figure 1. That is, the outer wall A at the corner was covered with an accessory B having a mountain-shaped cross section, and the accessory B was fixed by driving nails C through the outer surface of both ends thereof. As a result, the nail heads were directly exposed on the surface of accessory B, which had the disadvantage of impairing its appearance and waterproofing properties. Furthermore, in order to drive the nail C, the surface of the accessory B was left with dents and deformed. In addition, the accessory B itself lacked rigidity because it was simply roll-formed from a 0.27 to 0.35 mm metal plate at right angles, and there was also a risk of rainwater, wind, etc. entering from both ends.

In order to eliminate these drawbacks, the present invention has a cross-sectional structure that prevents the deformation of accessories and improves waterproofness, and also has a hard spacer interposed between the exterior wall material and the accessories to prevent protruding corners. We propose a projecting corner structure that enhances the appearance, strength, weather resistance, and waterproofness of the area.

An embodiment of the projecting corner structure according to the present invention will be described in detail below with reference to the drawings. FIG. 2 is a perspective view showing an embodiment of the above-mentioned projecting corner structure, in which 1 is a main pillar, 2 is a rim, and 3 is an outer wall material, for example, a siding material, which is connected to the rim 2 in a vertical joint shape. The outer wall was formed by Note that the outer wall materials 3 are each fixed to the rim 2 with nails 4. 5
is a spacer that can be nailed like a wooden board, slate board, or gypsum board, and is a rigid long body with a width of 50 to 200 mm and a thickness of approximately 5 to 15 mm.
The length is about 909-3636mm. This spacer 5 is arranged on the exterior wall material 3 at the protruding corner and is fixed by driving it into place with a nail 4. Since the spacer 5 itself is rigid, when driving the nail C, It is possible to prevent dents and dents from occurring on the exposed portion of the outer wall material 3. In addition, the spacer 5 fixes the outer wall material 3 at the protruding corner to prevent the end from flapping, and also functions as a backing material and a fixing piece for the corner accessory 6 described below, thereby preventing the corner accessory 6 from wobbling or deforming. At the same time, the corner accessory 6 can be easily fixed in a state where no nail heads are present on the decorative surface 7 of the corner accessory 6. Reference numeral 6 denotes a corner accessory, which is a long body having a decorative surface 7 having an isosceles mountain shape in cross section and a fixing portion 8 having both side edges of the decorative surface 7 bent inward at right angles, as shown in FIG. It covers the front surface 5a and outer surface 5b of the spacer 5. The corner accessory 6 is made of a thin metal plate (surface-treated steel plate, aluminum plate, copper plate), etc., and is formed by pressing or roll forming.

Next, a construction example will be explained.

First, spacers 5 are arranged as shown in the figure at the protruding corner of a building as shown in FIG. . Of course, since the outer wall material 3 is sandwiched by both members, it is securely fixed without flapping. Next, the corner accessory 6 is arranged as shown in the figure, and its fixing part 8 is fixed to the spacer 5 via the nail 4. In this case, it is more preferable that the height h of the fixing part 8 corresponds to the thickness of the spacer 5, or is smaller by Δt as shown in the figure, in order to avoid damaging the outer wall material 3 during construction.

What has been described above is only one embodiment of the projecting corner structure according to the present invention, and the corner accessory 6 can be formed as shown in FIGS. 4a to 4c. That is, FIG. a shows a corner accessory 6 in which the fixing part 8 is further bent outward at a right angle to form a receiving part 9 that provides stability.
The figure shows a corner accessory 6 in which the receiving part 7 is bent into a seam shape, and the figure c shows a corner accessory 6 in which the triangular parts where the decorative surfaces 7 intersect are chamfered. Others, spacer 5
can also be arranged as shown by two-dot chain lines in FIGS. 4a to 4c.

As described above, if the projecting corner structure according to the present invention is configured, nail heads will not appear on the decorative surface of the corner accessory, and corrosion resistance, waterproofness, and aesthetics will be greatly improved. be. Further, since the projecting corner portions are sufficiently reinforced by the spacers, they are not easily deformed by external forces, and there is an advantage that the projecting corner structure has a smooth projecting corner structure. Furthermore, since the construction is carried out after the exterior wall material has been constructed, there is no flapping of the edges of the exterior wall material, and it is easy to work, resulting in high efficiency.
