Description

[Detailed Description of the Invention] The present invention relates to a novel mounting structure for a decorative purlin having an attic ventilation function.

Conventionally, when fixing a decorative purlin to the gable side of a building for the purpose of attic ventilation, both sides of the hollow decorative purlin (main body) were opened at the top and closed at the tips with ventilation holes (vents) on both sides. The upper edge of the section is fixed directly to the roof of the eaves (Utility Model 1989-89812).
(Refer to No.), such a mounting structure requires labor to install, the hollow decorative purlin (main body) is not strong enough, and there are problems such as the ventilation openings spoiling the aesthetics.

The present invention aims to solve the above-mentioned problems, and consists of a hollow cosmetic purlin main body and an end cap having a ventilation hole attached to the front end of the main body. At least two mounting angle fixing parts and a hollow cosmetic purlin main body fixing part are bent at right angles in the hollow part of the hollow cosmetic purlin body, respectively, at the upper side and the lower side of both sides, respectively.
Two reinforcing plates are interposed and fixed at predetermined intervals and parallel to the end cap via the hollow decorative purlin main body fixing part, and the hollow decorative purlin main body is fixed at a predetermined position of the eave ceiling by the reinforcing plates. The above object has been achieved by providing a mounting structure for a decorative purlin having an attic ventilation function which is fixed and fixed by the mounting angles via the respective mounting angle fixing parts.

An embodiment of the present invention will be described below with reference to the drawings.

In the drawing, reference numeral 1 denotes a decorative purlin fixed to the gable side of the building, which includes a hollow decorative purlin main body 3 fixed to the eaves 2 of the building in a manner described later, and an end cap 4 attached to the front end of the main body 3. It is composed of.

The end cap 4 has a shape that can be adapted to the hollow decorative purlin main body 3, and has a ventilation opening 40 of a glazed structure at its front end and a water drain part 41 communicating into the hollow part of the main body 3 at its lower side. Each is provided.

The hollow decorative purlin main body 3 is made of a steel plate or plastic coated with vinyl chloride resin and has a U-shaped cross section, and at least two reinforcing plates 30, 30 are interposed and fixed at a predetermined interval in the hollow part. At the same time, the reinforcing plate 30,
30 is mounted and fixed via a pair of mounting angles 31, 31, so that its front end protrudes beyond the gable 5 and its rear end contacts the wall on the gable side of the building, so that it can be attached to the eaves of the building. It is fixed on the bottom side. Further, 32, 32 are parting edges that close the space between the eave ceiling portion 2 and both upper edges of the hollow decorative purlin main body 3, and are fixed along both upper edges of the main body 3, respectively. The eave top plates 21, 21 are clamped and fixed. Furthermore, a waterproof plate 33 is provided on the lower front inner side of the hollow decorative purlin main body 3 so as to provide a water slope in the direction of the water drain portion 41 of the end cap 4. The contact portion between the waterproof plate 33 and the hollow decorative purlin main body 3 is filled with caulking material.

To explain the above configuration in more detail, the pair of mounting angles 31, 31 are attached to the eave soffit base material 20 on both sides of the opening 7, which is normally provided in the eave soffit 2 to communicate with the attic. For example, it is fixed together with the parting edges 32, 32 by nailing. Further, the reinforcing plates 30, 30 have mounting angle fixing parts 30a, 30a and hollow decorative purlin main body fixing parts 30b, 30b bent at right angles, respectively, on the upper and lower sides of the reinforcing plates 30, 30. , 30 is attached to the pair of mounting angles 31, 31 with the mounting angle fixing part 30
It is fixed by screwing a and 30a. Two or more reinforcing plates 30, 30 are provided in order to reinforce the hollow decorative purlin body 3 and to stabilize and horizontally fix the hollow decorative purlin body 3. Note that the reinforcing plates 30, 30 are shaped so that a ventilation passage 8 is formed between them and the main body 3 when the hollow decorative purlin main body 3 is installed on both sides of the upper edge and on the outer side of the lower edge. It is preferable to leave it alone. Further, it is preferable that the reinforcing plate 30 located at the front is attached close to the waterproof end cap 4 as long as it does not impede the ventilation function. The hollow decorative purlin main body 3 is covered with the reinforcing plates 30, 30, with both upper edges of the reinforcing plates 30, 30 in contact with the inner sides of the parting edges 32, 32.
0.30 hollow decorative purlin main body fixing parts 30b, 30
b, 30b, and 30b with screws. In addition, as shown in the drawing, the hollow decorative purlin main body 3
The upper surface of the part protruding from the gable 5 is closed by a top plate 3', and when attaching the end cap 4, at least the upper part of the front end of the hollow decorative purlin main body 3 has a gap between it and the end cap 4. A caulking material 9 is applied to prevent rainwater from entering. Further, reference numeral 42 denotes a caulking material support piece which is protruded from the inside of the end cap 4 in order to support the caulking material 9 from below.

In the embodiment, the hollow decorative purlin 1 is not provided on the eaves 2 below the roof top, so the hollow decorative purlin main body 3 and the reinforcing plates 30, 30 are not shaped symmetrically, but Lower eaves 2
In the case where they are provided in both sides, they can have a laterally symmetrical shape.

In the hollow decorative purlin 1 constructed as described above, the attic can be ventilated through the opening 7, the hollow part of the hollow decorative purlin main body 3, and the ventilation opening 40, as shown by the arrow.

In addition, the caulking material 9 prevents rainwater from entering the hollow part of the hollow decorative purlin main body 3, but even if rainwater should enter the hollow part, the rainwater is blocked by the front reinforcing plate 30. The water is prevented from entering the rear of the hollow part, and the water is drained downward from the water drain part 41 of the end cap 4 along the water gradient of the waterproof plate 33, so that it does not remain in the hollow part, and the lower side of the hollow decorative purlin main body 3. It never leads to.
The lower side part is thus freed from dirt.

In addition, when installing the hollow decorative purlin main body 3, the installation angles 31, 31 and the reinforcing plates 30, 3
0 are combined and fixed in advance, and the mounting angles 31, 31 are attached to the eave ceiling part 2, together with the cutting edges 32, 32.
That is, after attaching and fixing to the eave ceiling base material 20, the hollow decorative purlin body 3 is fixed to the reinforcing plates 30, 30, or the mounting angles 31, 31, the reinforcing plates 30,
30 and the hollow decorative body are combined and fixed, and the above-mentioned mounting angles 31, 31 are attached and fixed to the eave ceiling part 2 together with the parting edges 32, 32.

As described above, according to the mounting structure of the decorative purlin with the attic ventilation function of the present invention, the hollow decorative purlin main body can be easily and securely attached to the eave roof without requiring any effort, and can be reinforced with a reinforcing plate, and since the ventilation opening is provided in the end cap with a glazed structure, for example, the appearance can be made beautiful.
