Description

[Detailed description of the invention] This invention is a structure with a relatively long arcuate roof that is used for, for example, an outdoor breezeway, a pedestrian bridge, a sunroom attached to a building in the style of a shed, a light fixture, a greenhouse, or a carport. (herein referred to as an arch-shaped construct).

Generally, this type of structure consists of an arched vertical frame made of extruded aluminum or steel sections, a horizontal frame made of the same material as the vertical frame connected to both ends of the vertical frame, and a horizontal frame made of the same material as the vertical frame. However, in order to form a relatively long structure, it is necessary to connect the unitized arch-shaped construction units,
It is believed that building a long-dimension structure is convenient in terms of strength and on-site construction. However, in this conventional structure, there were problems such as not only the appearance of the connecting portion was impaired, but also the rain closing mechanism was insufficient.

This invention was made with the intention of solving the above problem, and when connecting arch-shaped structural units that have been assembled in advance, it is necessary to straddle the outside of the connecting flanges of both adjacent structural units. , and by installing a cover material that cooperates with the facing plate mounting flange of the arched vertical frame constituting the structural unit to form a watertight sealing groove in the mounting part of the facing plate, thereby reducing the gap between the vertical frames of both structural units. They can be connected in the same plane without opening the parts, and the connecting parts are closed with a cover material, and the cover material works together with the face plate mounting flange to form a watertight seal groove for the face plate mounting part. Therefore, it is possible to reduce the cost by reducing the number of parts,
Moreover, the present invention aims to provide an arch-shaped structure characterized by a rain-shrinking mechanism that can be operated satisfactorily.

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

Figures 1 and 2 are perspective views showing different ways of using the structure of this invention. This is the case when used for lighting.

In the figure, reference numeral 1 denotes an arch-shaped construction unit, which connects a pair of arch-shaped vertical frames 2, 2 made of, for example, extruded aluminum sections, and both ends of these vertical frames 2, 2. It is composed of horizontal frames 3, 3 formed from a pair of extruded aluminum sections, and a flexible synthetic resin face material 4 interposed in the space between these vertical frames 2 and horizontal frames 3. ing. Construction units 1, 1 configured in this way
The arch-shaped structure of this invention is formed by connecting them to each other. At this time, in this invention, the vertical frame 2 is located on the indoor side as shown in FIGS. 3 and 4. a connecting flange 5,
A face plate mounting flange 6 protruding almost perpendicularly from the outdoor side of the connecting flange 5, a protrusion 7 protruding from the connecting side of the connecting flange 5, that is, the side opposite to the face plate mounting flange 6, The flange 6 is composed of a protrusion 8 whose cross section is approximately L-shaped and which protrudes toward the indoor side from the tip side of the flange 6. Both flanges 5 with a liner 9 interposed therebetween,
5 are fixed with bolts 10 and nuts 11, and then on the outdoor side of the face material 4 which is fixed with screws 13 and washers 14 via synthetic rubber packing 12 to the outdoor surface of each face material mounting flange 6. A cover material 15 formed of an arch-shaped extruded aluminum member is installed astride both vertical frames 2, 2,
At this time, this cover material 15 and the face material mounting flange 6 cooperate to form a watertight seal groove 16 in the mounting portion of the surface material 4, and a back-up material 17 is inserted into the watertight seal groove 16 of this mounting portion. The mounting screw 19 passing through the mounting hole 15 drilled in the cover material 15 from the outside of the cover material 15 is filled with a silicone-based wet sealing material 18.
A cover material 15 can be attached by screwing between the holes 7 and 7. In this case, the exposed portion of the mounting screw 19 on the outdoor side is covered with a sealing material 20 to maintain air-water tightness of the mounting portion.

Note that a connecting portion inner cover material 21 having a substantially square cross section is attached to the indoor side of both the connected vertical frames 2, 2. In this case, the inner cover material 21 of this connecting part has a fixing screw 22 passing through a mounting groove 21a in the center thereof between another protrusion 23, 23 that protrudes from the connecting surface on the indoor side of the connecting flanges 2, 2. It is attached by screwing into the

On the other hand, as shown in FIG. 5, the horizontal frame 3 has a panel mounting surface 26 formed on the outdoor side of a horizontal frame main body 25 having a hollow rectangular cross section that is fixed to a mounting bracket 24 fixed to the base part B. At the same time, a screw receiving recessed line 27 protrudes outward from this panel mounting surface 26.
The outside of the panel 4, which is in contact with the panel mounting surface 26 through the packing 12 and fixed by the screws 13 and washers 14, is attached to the screw receiving concave strip 27. It is covered with a cover material 29 fixed with screws 28, and the seal material 18 is filled through the back-up material 17 into the mounting seal groove 30 formed by the cover material 29 and the face material mounting surface 26. As a result, the attached state of the face material 4 and the horizontal frame 3 is maintained in an air- and water-tight manner.

In FIG. 1, reference numerals 3' and 3' are intermediate crosspieces that can be attached between the vertical frames 2 and 2 as needed, and those having the same shape as the horizontal frame 3 are used.

As explained above, according to the arch-shaped structure of this invention, the arch-shaped vertical frame, in which the connecting flange is formed on the indoor side and the panel mounting flange is formed on the outdoor side, is arranged vertically at intervals. An arch-shaped construction unit consisting of a horizontal frame connecting the ends of these vertical frames and an arch-shaped panel interposed between these vertical frames and horizontal frames can be assembled in advance, and on-site, When connecting construction units, a cover is installed over the outside of the connecting flanges of both adjacent construction units, and cooperates with the facing material mounting flange to form a watertight sealing groove for the mounting portion of the facing material. Since the cover material is attached to the face material mounting flange, it is possible to easily connect the structural units on the same plane as in the past, and also to close the gap between the connecting parts. Since they work together to form a watertight sealing groove at the mounting part, it is possible to reduce the number of parts, reduce costs, and also allows for a good rain shut-off mechanism. Excellent effects such as these can be obtained, and its utility value is remarkable.
