Description

[Detailed explanation of the invention] This invention is a building exterior that can be easily assembled by the same construction regardless of whether it is an existing building or a newly constructed building, and has good rain protection using the isobaric principle. It concerns the structure of the division.

With general curtain walls that use the equal pressure principle, it is difficult to completely prevent rainwater etc. from entering from the outside air intake port, so it is difficult to completely prevent rainwater etc. from entering from the outside air inlet. It was necessary to form a gutter to drain out raindrops etc. that entered the structure. However, these water return plates, gutter sections, etc. must be attached separately from the base for mounting the exterior panel, that is, the vertical and horizontal frames, which requires a lot of labor and time, and is extremely difficult to install.

This idea was developed in view of the above circumstances, and includes vertical and horizontal frames on the outside of the building frame, and an exterior panel consisting of multiple panel pieces that can cover the frames. A building exterior structure in which a space is formed between the attached exterior panel and the building frame, wherein the space is supplied through an outside air inlet provided at a connection between the top and bottom of each panel piece. By making the inside pressure equal to the outside air pressure, and by forming a water return piece on the horizontal frame adjacent to the outside air inlet to cover the outside air inlet, construction can be simplified. The present invention aims to provide an exterior structure for a building that is characterized by the following features.

Examples of this invention will be described below based on the drawings.

Figure 1 is a front view showing an example of renovation in which the exterior structure of a building of this invention is attached to the outer surface of the exterior wall board applied to the exterior of the existing building frame. In the figure, 1 is the sash forming the opening. , 2 is an exterior panel forming the waist part. In this case, the plurality of panel pieces 2' constituting the exterior panel 2 are fixed to the outer surface of the ALC or calcium silicate board B and tile material C constituting the building frame A, as shown in FIGS. 2 to 4. A vertical frame 4 is disposed with fasteners 3 having brackets 5', and a vertical frame 4 is disposed with fasteners 5 having brackets 5'. It is attached to the outer surface of the horizontal frame 7 that is connected to the horizontal frame 7. That is, the connecting portions in the left-right direction of each panel piece 2', 2' are connected at appropriate intervals to the outer flange 8a of the reinforcing frame 8, which has a substantially Z-shaped cross section and is attached to the side end of each panel piece 2', 2'. As shown in FIG. 5, the plurality of adjacent notches 8b formed in the vertical frame 4 are attached to the outer surface of the vertical frame 4 by engaging with each other, and a batten 9 having a C-shaped cross section is attached to the outer surface. is applied to cover the vertical frame 4. Further, the vertical connection portion of each panel piece 2', 2' is formed by connecting an outer flange 10a of a mounting piece 10 bent in a substantially L-shape to the upper and lower ends of each panel piece 2', 2', respectively, to a horizontal frame 7. At the same time, a batten 11 having a substantially C-shaped cross section is attached to the outer surface of the joint, and the horizontal frame 7 is similarly covered by the exterior panel 2.
A space 12 is formed between the exterior panel 2 and the building frame A. This space 12 is communicated with the outside air through an outside air inlet 13 formed in the mounting piece 10 of the panel piece 2' located above at the upper and lower connecting portions of the panel pieces 2', 2'. 1
2 The inside pressure is equal to the outside pressure. In this case, even if the outside air inlet 13 is provided in at least one of the reinforcing frames 8 at the left and right connecting portions of the panel piece 2', the pressure inside the space 12 can be made equal to the outside pressure.

In the above structure, there is a risk that rainwater etc. may enter the space 12 through the outside air inlet 13, so in this invention, the outside air side of the horizontal frame 7 adjacent to the outside air inlet 13 is A water return piece 1 that extends from the top so as to cover the outside air inlet 13
At the lower part of the frame side of the horizontal frame 7, there is a vertical frame 1 which catches raindrops that jump over the water return piece 14 and enter the space 12, and which will be described later.
A horizontal frame 15 that feeds the feeder 6 is integrally formed. Then, the vertical frame 4 is connected to the horizontal frame 7 with the support 6.
A vertical gutter 16 communicating with the horizontal gutter 15 is integrally formed on the side surface of the vertical gutter 16 . With this configuration, rainwater or the like that tries to enter the space 12 from the outside air inlet 13 is blocked by the water return piece 14, and in the event that it jumps over the water return piece 14 and enters the space 1.
Even if the inside of the space 2 is invaded, it is caught by the horizontal gutter 15, and combined with the equal pressure action within the space 12, it is discharged to the outside by the horizontal gutter 15 and the vertical gutter 16. Furthermore, there is no risk of rainwater or the like entering the structure.

In the above embodiment, the case where exterior panels are attached for renovation of an existing building was explained, but of course, vertical frames 4 and horizontal frames 7 are similarly arranged on the outside of the structure in newly constructed buildings. It is also possible to attach an exterior panel 2 to the outer surfaces of both frames 4 and 7.

As explained above, the building exterior structure of this invention makes the pressure in the space between the exterior panel and the building frame equal to the outside pressure by the outside air inlet provided in each panel piece that makes up the exterior panel. Therefore, it is possible to form a rain cover that utilizes the principle of equal pressure, and also to prevent rainwater from entering the space through the outside air inlet and by jumping over the water return piece. Furthermore, it has a gutter section that catches raindrops that try to enter the space and discharges them to the outside, making it possible to better control the rain.
Moreover, since the water return piece and gutter part are formed on the base itself for attaching the panel piece, it has excellent effects such as reducing labor and time during construction, and its utility value is remarkable. .
