Description

  The present invention relates to an exterior material erection structure such as a roof or a wall.

In a conventional exterior material erection structure, the roof surface design is generally formed only by a roof panel.
For example, in the “roof panel mounting structure” described in Patent Document 1, a roof panel is fixed to an upper chord member in a truss structure as a gantry, and this roof surface design has an appearance. It is a general roof surface design such as a gable, a single flow, etc., which is formed only by the roof panel to be formed.
By the way, a gantry made of a truss structure has features such as a long span, a lightweight finish, and a sufficient structural strength, which are highly useful.
JP 7-259237 A

  The problem to be solved is that, first of all, the unique features of the truss structure such as a long span are utilized, the support of the exterior material is strong, and the exterior design is made up of the exterior material and the upper chord material. A design exterior material erection structure, secondly, an exterior material erection structure that excels in rain and drainage functions, and third, an exterior material erection structure that is brighter on the lower or inner side of the exterior material There is.

In order to achieve the above-mentioned problems, the present invention is characterized by the following configuration.
1. In the exterior material erection structure in which the exterior material is supported by a gantry, the gantry is composed of a three-dimensional truss structure composed of an upper chord material, a lower chord material, and a diagonal material. A lower receiving bracket is extended from the joint portion so as to follow the diagonal member, and an exterior material is installed along the diagonal member between the diagonal upper receiving bracket and the lower receiving bracket. To do.
2. In 1 mentioned above, the ridge member straddling the adjacent exterior material upper end part is arrange | positioned in the upper junction part, and the eaves member over the adjacent exterior material lower end part is arrange | positioned in the lower junction part, respectively. And
3. In 1 or 2 described above, the exterior material is a translucent material.

A. According to the first aspect of the present invention, since the gantry is a three-dimensional truss structure, the exterior material is strongly supported together with the features as the truss structure. The strength of the truss structure itself is increased by the exterior material.
Since the gantry is a three-dimensional truss structure and the exterior material can be installed along the diagonal of the truss structure, the exterior material is appropriately flow-graded according to the inclination angle of the diagonal without tilting the gantry itself. Can be installed.
Since the exterior material is installed along the diagonal of the truss structure, the exterior material will not protrude upward on the gantry, that is, the upper chord material, and the exterior design supports the exterior material and this exterior material. It becomes the thing of the novel external appearance design which is comprised with the upper chord material in the truss structure which is.
B. According to the second aspect, the rain performance and the drainage function are further excellent.
C. Further, the lower side or the inner side of the exterior material can be brightened.

The gantry consists of a three-dimensional truss structure consisting of upper chord material, lower chord material, and diagonal material. The upper metal fitting is connected from the upper joint of the upper chord material and diagonal material to the lower chord material and diagonal material. A lower metal fitting is extended from the lower joint portion of the joint portion so as to follow the diagonal material, and an exterior material is installed over the diagonal upper metal fitting and the lower metal fitting.
In principle, such an exterior material is attached to upper and lower metal fittings. However, when the assumed load condition of the exterior material is low and the allowable load of the oblique material is large, the exterior material may be fixed to the oblique material. Similarly, when the allowable load of the upper chord material and the lower chord material is large, they may be fixed to them.
The upper and lower metal fittings straddle each diagonal member in a specific direction such as an aspect made of piece-shaped mounting brackets respectively arranged at upper and lower joints in a three-dimensional truss structure, a direction of crossing, or a direction crossing this. In this way, an aspect composed of a long support member disposed in a vertically parallel manner, a piece-shaped mounting bracket respectively disposed at each of the upper and lower joints in the three-dimensional truss structure, Any one of the aspects comprising the long support members arranged in parallel vertically so as to straddle each diagonal member over the respective mounting brackets in a specific direction such as a crossing direction, etc. good.
Support members that are parallel to the top and bottom are attached to the top and bottom mounting brackets, but they may also be attached to diagonal materials, and can be constructed by making it possible to fix the exterior material at any position in the direction of crossing or in the crossing direction. In addition to improving the performance, the upper chord material or the lower chord material can be supported.
The exterior material may or may not be a member constituting the roof or wall. In the case of a roof, for example, it may be formed of an upper ridge member, a lower ridge member, a cover member, a roof material, and a roof member, and the lower ridge member may also function as an upper chord material. Further, the space formed between the upper ridge member and the lower ridge member may or may not be used as the rain closing space of the upper joint portion.
The exterior material is made of a metal plate (such as a decorative steel plate) such as iron, aluminum, or stainless steel, a glass plate, a resin plate, or other known water-impermeable materials. Of these, glass plates, resin plates (typically made of polycarbonate), and the like have translucency. Further, as an example of a combination of exterior materials, a metal plate that does not transmit light and a resin plate that transmits light may be used in combination. That is, it can be adopted for any of the full daylighting type, the partial daylighting type, and the whole daylighting type.

FIG. 1 illustrates an embodiment of an exterior material erection structure according to the present invention. A gantry 2 that is laid across a column 1 is a three-dimensional truss structure composed of an upper chord member 3, a lower chord member 4, and a diagonal member 5. Formed in the body.
