Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure suitable for various small structures such as a bicycle parking lot and a bus stop.

[0002]

2. Description of the Related Art Conventionally, in the roof structures of these various small structures, an ordinary rain gutter which is attached to the eaves of ordinary houses is attached.

However, a normal rain gutter attached to the eaves of a general house is expensive as a roof structure for a small structure, which leads to a high construction price, and is placed outside the small structure, and in addition to the small structure. There was a problem that the appearance was impaired because the balance could not be achieved.

Therefore, the present applicant uses H-section steel as the aggregate of the girder and installs a gutter substitute frame made of channel steel in the longitudinal direction of the inner surface of the flange of the girder to form the long groove. , Proposed a roof structure for small structures that solves the above problems.

[0005]

However, even in the above roof structure, since the gutter substitute frame is installed on the inner surface of the girder flange, it is difficult to remove dust and dirt accumulated in the long groove. Was.

Further, in the above roof structure, since the channel steel installed as a gutter substitute frame has a large weight and is easily rusted, there is a problem that the construction is difficult and the durability is poor.

Therefore, the present invention solves the problems of the above-mentioned conventional roof structure, and makes it easy to clean the dust and dirt accumulated in the rain gutter and to reduce the weight and the rust of the rain gutter. In addition, the roof structure of the small structure is inexpensive, and the purpose is to provide a roof structure in which the rain gutter is placed inside the small structure and does not appear in the appearance and does not impair the appearance. Is.

[0008]

Therefore, in the roof structure of the present invention, brackets are installed at at least two positions in the longitudinal direction of the flanges of the girders made of H-shaped steel, and the flanges of the girders between the brackets are installed. The rain gutter is laid over the protruding position, one end of the rafter to which the roofing material is attached is installed at the outer end of the bracket, and the rafter is arranged above the gutter groove of the rain gutter. The bracket may be installed on the upper flange or the lower flange of the girder. Further, the rain gutter can be made of synthetic resin or aluminum.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a roof structure according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 illustrates a compact construction having a flat roof embodying the roof construction of the present invention.

The basic skeleton of this structure is made of H-shaped steel, using front columns 1, 1, front girders 2, rear columns 3, 3, rear girders 4,
It is composed of left and right girders 5 and 5. A plurality of rafters 6 ... Are hung between the front girder 2 and the rear girder 4, and a roof material (not shown) is attached between these rafters 6. In the longitudinal direction inside the upper flange 2a of the front girder 2 made of the H-shaped steel, a plurality of supports 7 are installed at regular intervals by welding, screwing or bolting, and are made of the H-shaped steel. A plurality of brackets are provided at regular intervals in the longitudinal direction inside the upper flange 4a of the rear spar 4 (see FIG. 2) or inside the lower flange 4b (see FIGS. 4 and 6) or outside (see FIG. 8). 8 is installed by welding, screwing, bolting, or the like. The front and rear ends of the rafter 6 are installed on the outer ends of the support 7 and the bracket 8 by welding, screwing or bolting, and the upper flange 4a of the rear girder 4 between the brackets 8 ... Lower flange 4
It is assumed that a rain gutter 9 made of synthetic resin or aluminum is laid over the position protruding from b. Therefore, the upper flange 2a of the front girder 2 is shielded by the roof material attached between the rafters 6 and the rain gutter 9 is provided at a position protruding from the upper flange 4a or the lower flange 4b of the rear girder 4. The trough 10 is formed, and the rafters 6 ... Are arranged above the trough 10. Further, since the rain gutter 9 is made of synthetic resin or aluminum, the rain gutter 9 is lightweight and rustproof.

In the roof structure of the present invention constructed as described above, since the upper flange 2a of the front girder 2 is shielded by the roof material, it is possible to prevent rain from being blown between the front girder 2 and the roof material during rainy weather. Since the gutter groove 10 is formed on the upper flange 4a or the lower flange 4b of the rear girder 4, the rain flowing down from the roof material flows into the gutter groove 10. Further, since the gutter groove 10 is formed at a position protruding from the upper flange 4a or the lower flange 4b of the rear girder 4,
It becomes easy to insert a hand, a broom, etc., and it becomes easy to clean the dust accumulated in the gutter groove 10.

The roof structure of the present invention can be applied not only to the flat roof described above, but also to various roofs. For example, in the gable type and arch type roofs shown in FIG. 9 and FIG.
It may be set at an appropriate angle as shown in FIG. That is,
In a gable type or arch type roof, a plurality of brackets 8 are installed at fixed intervals in the longitudinal direction of the upper flange 2a of the front girder 2 made of the H-shaped steel by welding, screwing or bolting. In the longitudinal direction of the upper flange 4a of the rear girder 4 made of H-shaped steel, a plurality of brackets 8 are installed at regular intervals by welding, screwing or bolting. The front and rear ends of the gable-shaped or arch-shaped rafter 6 are installed on the outer ends of the brackets 8 by welding, screwing or bolting, and the front girder between the brackets 8 ... It is assumed that a rain gutter 9 made of synthetic resin or aluminum is laid over the position protruding from the upper flange 2a of the rear girder 2 or the upper flange 4a of the rear girder 4. Therefore, the upper flange 2 of the front girder 2
a and a position where the rear girder 4 protrudes from the upper flange 4a, a gutter groove 10 is formed by a rain gutter 9, respectively.
Are arranged above these troughs 10.

[0014]

Since the roof structure of the present invention is constructed as described above, it becomes easy to clean the dust accumulated in the rain gutter. Further, the roof structure of the present invention,
The rain gutter can be made lighter and more rust-proof, and the construction is simple and has excellent durability. Further, the roof structure of the present invention is inexpensive as a roof structure for a small structure, and the rain gutter is placed inside the small structure so that it does not appear in the appearance and the appearance is not impaired.
