Description

[Detailed description of the invention] This invention relates to an attachment structure for an eaves soffit board that is attached to the lower part of an arm that has a frame for attaching a fascia board at its tip, which is extended outward by the upper beam of a house such as a prefabricated house. In particular, the rim part on the inner end side of the eaves soffit board is fixed to a bracket fixed to the building side, and the tip of the eaves soffit board is attached to an upward hook on the inner end of the channel-shaped decorative material provided on the frame. The downward hook formed in the frame is engaged to ensure temporary attachment, and the downward support bracket fixed to the lower part of at least one of the arm and frame is brought into contact with the upper surface of the eave ceiling board. This is a design related to a structure for attaching eave ceiling boards that can withstand mounting stress and wind pressure from below.

<Prior Art> As is well known, many modern houses are designed with fascia boards such as eaves decorative boards, and in this construction, the fascia board is attached to the tip of the arm via an arm that extends outward from the building side. A frame is provided to which the fascia is attached, and a fascia board such as an eaves decorative board is attached to the frame.

Incidentally, from the viewpoint of design and protection against wind and rain, it is becoming increasingly common to attach eave ceiling boards to arms extending from buildings from below.

<Problems to be solved by the invention> However, as shown in FIG. Even if it is possible in principle to install the eave ceiling board 1 by hand,
When attaching the inner end 2 to the building 3 side and attaching the outer end 5 to the frame 4 on which the fascia plate is attached, there is a problem that it is difficult to temporarily fasten it, and there is also a problem that it is easy to fall off. The disadvantage was that it required skill.

In addition, as shown in FIG. 2 after the temporary fixing is done, when attaching the tapping screws 7, 7 to the angle member 6 for joint treatment between the eave top boards 1, the bottom of the eave top boards 1 is Since the soffit board 1 is long, the flexibility of the eave ceiling board 1 prevents the drilling from the side, and there is a risk that the drilling may be difficult, insufficient, or inaccurate.

Furthermore, joint treatment may be insufficient, or even if treatment is possible, the area of each part of the eaves ceiling board 1 is large, and therefore it cannot withstand wind pressure such as so-called blow-up, resulting in vibration, distortion, peeling, and falling. There was also the inconvenience that it became easier to do.

The purpose of this invention is to solve the above-mentioned problem of installing the eave ceiling board as a technical problem, and to attach the rim part of the inner end of the eave ceiling board and the downward hook of the outer end to the building's bracket and the fascia plate. Temporarily attach the upper hooks at the bottom of the frame with one touch, and
A supporting bracket for the eave ceiling board is attached to the lower part of at least one of the arm and the frame at the tip thereof, so that it can resist the pressing force during construction from below, and is applied to the field of housing construction technology application in the construction industry. The purpose of the present invention is to provide an excellent eave ceiling board attachment structure that will benefit the user.

<Means and effects for solving the problem> In accordance with the above-mentioned purpose, the structure of this invention, which is based on the scope of the above-mentioned utility model registration claim, is to solve the above-mentioned problem. With a single touch, the downward hook is engaged with the upward hook provided at the bottom of the frame for attaching the fascia plate provided at the end of the arm extending outward from the building, and the rim portion at the inner end is attached to the receiving part on the building side. It engages with the metal fittings to securely temporarily attach it, prevent it from shifting inward and outward, and prevent it from falling off.In addition, during the actual installation, the support bracket provided at the bottom of at least one of the arm and frame supports the soffit board. By contacting the top surface, upward force is suppressed, making it possible to perform joint processing such as screwing and joining to brackets smoothly, and the corner corners can withstand wind pressure from below. This is a technical measure.

<Example> Next, an example of this invention will be described below based on the drawings from FIG. 3 onwards.

Reference numeral 9 denotes an arm, with both edges up and down and its base facing the upper beam 11 of the building side 10 at its flange 12.
is fixed by bolts 13, 13 through the lower edge 1
4, an L-shaped support bracket 16 having a flange 15 at the lower end is welded and fixed in advance at the factory.

A notch 18 for a rain gutter and a substantially inverted triangular groove 19 are formed in the front part of the upper edge 17, and the front end is inclined in an overhanging shape toward the lower part of the front, and the flange 20 is formed at a right angle. It spreads laterally.

Reference numeral 21 denotes a frame, and a vertical bar 22 is integrally welded to the inner surface of the frame at a right angle at the factory.By bringing the frame 21 into surface contact with the flange 20 of the arm 9 and sliding it down, the lower side surface of the vertical bar 22 is attached. The implanted hook pin 23 is positioned by engaging with the groove 19, and the frame 21 is attached to the arm 9 by inserting and tightening the bolt 24 into a hole previously drilled in the arm 9 and the vertical bar 22. is designed to be assembled.

Reference numeral 25 designates a decorative eave board of the fascia board, which is fixed to the outside of the frame 21. A channel-shaped decorative material 26 that slopes inwardly downward is properly fixed to the lower end of the decorative board, and a valley is formed at the inner end of the decorative board. An L-shaped upward hook 27 is formed.

Note that the decorative material 26 may be fixed to the arm 9.

Reference numeral 28 designates another support bracket, which has an inverted U-shaped cross section, and its base is welded and fixed to the inward flange 29 at the lower end of the frame 21, and its inner end flange 30 is connected to the flange 15 of the support bracket 16. The support brackets 28, 28, . . . are arranged at predetermined intervals in the longitudinal direction of the frame 21, as shown in FIGS. 3 and 6.

Reference numeral 31 denotes a channel-shaped receiving fitting with a J-shaped cross section, and spring clips 32 are welded and fixed in advance at predetermined intervals on the inner surface of the fitting as shown in FIG. Fixed.

Reference numeral 34 designates an eaves top board, the outer end of which is bent downward at right angles to form a downward hook 35, and the inner end has a U-shaped rim portion 36 that is inverted upward. is formed.

Incidentally, 37 is a tapping screw for attachment.

In the above configuration, the frame 2 is also connected to the arm 9 fixed to the building 10 side as described above.
When attaching the eaves top board 34 with the eave top board 34 attached, first, as shown in FIG. Bracket 2 like the arrow
8 and the upward hook 27, and when the downward hook 35 is lowered, the tip of the downward hook 35 falls into the valley of the upward hook 27 due to the valley structure shape of the upward hook 27. It is set so that it cannot be moved back and forth.

In this state, the rim part 36 at the inner end is moved between the bracket 31 and the clip 32 while bending the eave top board 34 to reduce its inner and outer widths using the flexibility of the eave top board 34 as shown in B. When inserted into the clip 32, the eaves ceiling board 34 is expanded by the spring elasticity of the clip 32 and engaged securely, and the rim portion 36 is clamped and fixed between the receiving fitting 31 and the clip 32.

Then, the eave top board 34 is extended by springback into the state shown in C, and its upper surface abuts the lower surfaces of the flanges 15, 30 of the support brackets 16, 28.

In this state, the flange 15 of the support bracket 16
A mounting hole is drilled from the underside of the eaves ceiling board 34, but since it is held down from above by the support bracket 16 and the support bracket 28,
The holes are accurately and smoothly drilled without bending the soffit board 34 upward, and as a result, the tapping screw 37 can be screwed in and assembled, and
The intended processing of each unit sheet of the soffit board 34 is similarly carried out without bending due to support from above by the brackets 16, 28.

Incidentally, the flange 30 of the support bracket 28 may also be fixed with a tapping screw, but it is not necessary.

In this case, as shown in FIG. 6, sufficient resistance to wind pressure such as blowing up at the corner portion D can be exerted to prevent flapping.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments, and that various other embodiments can also be adopted.

<Effects of the invention> As described above, according to this invention, in a structure in which a soffit board is attached to the lower part of an arm that extends outward from a building and has a frame for attaching a fascia board at its tip,
The rim part of the inside edge of the soffit board is inserted into the bracket on the building side and fixed, and the downward hook formed on the outside edge of the soffit board is attached to the frame at the bottom of the fascia board. By engaging the upward hook, basically, once the downward hook of the soffit board engages with the upward hook at the bottom of the fascia board, it becomes impossible to move forward or backward. This has the excellent effect that the rim part at the inner end is stably fixed to the bracket, and the temporary attachment can be performed reliably, and there is no risk of it slipping or falling off. be.

Furthermore, since the support bracket is fixed downward to the lower part of the arm and frame so that it comes into contact with the top surface of the soffit board, when drilling the mounting holes from below when processing or installing the soffit board, it is difficult to The soffit board does not bend upward, so that the holes can be reliably and accurately positioned, and there is an excellent effect that the soffit board can be assembled accurately and quickly.

In addition, in that case, the support bracket can also be secured with screws, making it possible to resist bending and wind pressure on the long soffit board, improving durability. If a support bracket is also provided on the frame and brought into contact with the top surface of the eaves top board, the wind pressure against the wind blowing up from below in the large area of the corner corner of the eave top board can be sufficiently resisted. This provides an excellent effect in that the eaves top board does not flap, and the eave top board does not fall off due to peeling off screws or the like.
