Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an entrance eave, and particularly to a structure of an entrance eave suitable for use in prefabricated houses.

[Conventional technology]

Traditional flat tile roofed entrance eaves are made up of many parts, and the manufacturing process begins with the assembly of the truss beams, followed by the installation of roofing boards, roofing, tile roofing, draining in various places, laying the base slabs, and building the gable walls. Many processes were required, such as installing roofs and eave ceilings, fixing eaves gutters with eaves gutter metal fittings, concealing them, and caulking, and it also took time and effort to waterproof the many connecting parts.

[Problem that the invention seeks to solve]

In view of the above-mentioned problems, an object of the present invention is to provide an entrance eave that has a small number of parts, is easy to manufacture, and does not require time and effort for waterproofing.

[Means for solving problems]

As shown in FIG. 1, on the outer wall W of the building along the upper edge of the entrance E, a plurality of mounting seats 31 and 32 are provided at predetermined intervals in the direction of the frontage of the entrance E and are exposed on the wall surface.
A right triangular truss beam 2 is attached to the vertical part 2 of the truss beam 2.
1, a roof panel 5 is disposed on the upper surface of the inclined portions 22 of the truss beam 2 so as to cover these, and the panel 5 is fixed to each of the inclined portions 22. An eave ceiling panel 6 is arranged on the lower surface of the horizontal portion 23 of the truss beam 2 so as to cover these, and the panel 6 is attached to each horizontal portion 2 of the truss beam 2.
Fixed at 3.

The above roof panel 5 and eave ceiling panel 6 and outer wall W
As shown in FIG. 5, the openings on both sides formed by the
It is covered with a gable wall panel 8, and its peripheral edges 81 and 82 are fixed to the side edges of both the panels 5 and 6 to form an entrance eave.

〔Effect of the invention〕

The entrance eave is constructed of a truss beam fixed to the outer wall of the building, and a roof panel, eave ceiling panel, and gable wall panel that cover the truss beam and are fixed to it, so there are very few components. Therefore,
It does not require much effort to manage parts and is easy to assemble. Also, since there are few connecting parts, waterproofing can be done in a short time.

In addition, since the vertical part of the truss beam is fixed to the mounting seat exposed on the exterior wall after the fireproof and waterproof exterior wall of the building is completed, the fireproof performance of the building itself will not be compromised when the eaves are installed. .

〔Example〕

FIG. 1 is a cross-sectional view of the eaves 1 projecting from the upper side of the entrance E. Inside the entrance eaves 1, truss beams 2 formed into a right-angled triangular shape are arranged at predetermined intervals in the longitudinal direction of the eaves 1.
At the lower end of 1, mounting bolts 31, 3 protrude from the outer wall W of the building having fireproof and waterproof properties.
It is fixed at 2. The heads of the mounting bolts 31 and 32 are welded and fixed to a support fitting 41 inside the building,
The support fittings 41 are bolted to a first floor ceiling beam 42 and a second floor floor beam 43. The vertical part 21 of the truss beam 2 is also screwed at its upper end to a horizontal timber 44 in the building.

A roof panel 5 is disposed on the upper surface of the inclined portion 22 of each of the truss beams 2 fixed to the outer wall W in this manner so as to cover these. Here, a plan view of the roof panel 5 is shown in FIG. 2, and a cross-sectional view taken along the line 5 is shown in FIG. The above panel 5 is an integrally molded aluminum cast product with acrylic coating applied to it.
The peripheral edge portion 52 is raised in a substantially U-shape for both reinforcement and drainage. General portion 5 surrounded by the peripheral portion 52
3 is formed into a tile pattern, and its cross section is sawtooth as shown in FIG. Further, its lower edge is concave to form a gutter portion 531 along the lower side of the roof panel 5 (FIG. 2), and the gutter portion 531 is provided with a drainage hole 531a as appropriate. Vertical ribs 51 are formed protruding from the lower surface of the general portion 53 at predetermined intervals in the width direction (Fig. 3), and the roof panel 5 is bolted to the inclined portion 22 of each truss beam 2 at the ribs 51. It is fixed (Fig. 1).

The upper end edge of the roof panel 5 fixed with bolts is in contact with the outer wall W of the building, and a waterproof caulking material 9 is applied to the contact portion.

Below the truss beam 2 there is a field edge 61 arranged in a lattice pattern.
The field edge 61 is secured and fixed by two rail-shaped hanging members 62 connected to each horizontal portion 23 of the truss beam 2 and bolted to the lower surface thereof in a structure described in detail later. ing. An eave ceiling panel 6 is attached to the lower surface of the roof edge 61, and the eave ceiling panel 6 is flush with the entrance ceiling board E1.

The end opening of the entrance eaves 1 formed by the roof panel 5 and the eave ceiling panel 6 is covered with an eaves decorative panel 7 which also serves as a rain gutter. The details are shown in FIG. The decorative panel 7 is an integrally molded product made of aluminum casting, and has a horizontal bottom part 71 and an upwardly sloping part that forms the entrance eaves 1.
and a side portion 72 that constitutes the distal end surface. The panel 7 has a notch 511 formed at the top end 721 of the side portion 72 at the tip of the rib 51 of the roof panel 5.
while the rear end 71 of the bottom part 71
1 is fixed between both panels 5 and 6 by screwing it to a field edge 61 located at the front edge of the eaves ceiling panel 6.

A standing wall 712 is provided on the upper surface of the bottom portion 71, and a concave portion 7a formed by the standing wall 712 and the side portion 72 serves as a rain gutter. That is, the recess 7
A drainage hole 713 from which a chain gutter 73 hangs is provided in the bottom part 71 constituting part a, and rainwater that falls from the drainage hole 531a of the roof panel 5 is received by the recess 7a as a rain gutter and drained. Hole 71
It is discharged from 2.

The triangular openings on both sides formed by the roof panel 5, the eave top panel 6, and the outer wall W of the building are covered with gable panels 8 as shown in FIG. Panel 8
has its upper and lower sides bent inward in an L-shape, and as shown in the figure, its upper bent portion 81 is screwed to the lower surface of the side edge of the roof panel 5, and the lower bent portion 82 is attached to the eaves 5.
It is screwed to the field edge 61 at the side edge. The middle portion of the panel 8 is supported by an angle member 85 provided on the upper end of the hanging member 62. Note that the field edge 61 is secured by an angle member 65 fixed to the lower surface of the end of the hanging member 62.

FIG. 6 shows the rear end of the gable wall panel 8 in contact with the outer wall W of the building. The rear end of the end wall panel 8 is bent into a Z-shape as shown in the figure, and a gap 8a is formed between it and the outer wall W, and an L-shaped angle member is pasted on the inside of the Z-shaped bent part. Combined with external wall W
A gap 8b is formed between the two. A waterproof caulking material 9 is filled in either of the gaps 8a, 8b via a foamed plastic material 84.

As described above, the entrance eaves of the present invention has a small number of components, and therefore can be easily assembled and waterproofed in a short time. In addition, since all parts can be assembled from the front side of the eaves and no assembly space is required on the side, assembly is easy even when there is an outer wall of the building in close proximity to the gable wall panel.

Furthermore, since the truss beams are fixed to mounting bolts that protrude from the wall surface after the building's exterior walls are completed, the fire and waterproof properties of the building itself can be maintained regardless of the installation of the eaves, making it possible to protect indoor features from eaves. By doing this in parallel with the installation, the construction period can be significantly shortened.
