Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field This invention relates to shapes, and particularly to shapes used as frame members in the construction of arch-like or dome-like structures.

BACKGROUND OF THE INVENTION Many arch-shaped or dome-shaped structures have been constructed as gymnasiums, indoor pools, greenhouses, etc., which have no pillars or other roof support members inside, allowing a large space to be obtained, and which are fully illuminated.

There is a desire for these structures to be easier to assemble and to reduce the number of parts.

In addition, since dew condensation occurs in these structures due to temperature differences inside and outside the structure, treatment of condensed water also poses a problem.

Conventionally, in these structures, as shown in FIG. 1, a connecting member 5 having a supporting part for holding a panel 3 and a recess 4 for guiding condensed water is a cylindrical body equipped with a protrusion 1. 2, the panel 3 was placed on the support member 4, and the panel 3 was fastened with bolts via the presser plate 6, which required a lot of effort to assemble.

In addition, since the panel 3 is supported using three members: the cylindrical body 2, the connecting member 5, and the holding plate 6, distortion may occur between each member when assembling the arc-shaped part of the structure. It was extremely difficult to bend the material so that it would not occur.

Purpose This invention was made in order to eliminate the above-mentioned conventional defects, and its purpose was to create a molded material that requires fewer parts and that can be easily assembled when assembling an arch-shaped or dome-shaped structure. Our goal is to provide the following.

EXAMPLE Hereinafter, an example embodying this invention will be described with reference to the drawings.In this mold material 10, an inverted-shaped fastening is provided on the upper surface of the upper wall 12 of the cylindrical body 11 having a rectangular cross section. A protrusion 13 is formed in the longitudinal direction, and a pair of protrusions 14 are provided on both sides of the tightening protrusion 13, which also serves as a gutter for condensed water to flow.

An uneven anti-slip portion 15 is formed on the upper portion of the inner surface of the protrusion 14 that faces each other.

Hook-shaped protrusions 17 are formed along the longitudinal direction of the outer surface of the lower end of both side walls 16 of the cylindrical body 11, and together with the side walls 16, guide grooves 18 are formed.

Next, the operation of the mold material 10 configured as described above will be explained.

Now, this profile 10 is bent into an arc shape as shown in FIG. 3, and is mainly used as a meridian member of an arch-shaped structure.

When assembling a structure using this mold material 10, as shown in FIG. A panel 20 made of
The assembly is completed by firmly tightening and fixing the panel 20 and the presser member 21 to the mold material 10.

In this case, the joint between the holding member 21 and the panel 20 is filled with a caulking material 23 to prevent rainwater from entering.

The continuous groove 24 formed by the packing 19a, the protrusion 14, and the upper surface of the upper wall 12 serves as a gutter for draining condensed water generated on the inner surface of the panel 20 due to the temperature difference between the inside and outside of the structure.

As shown in FIG. 6, the beam material 25 is cut out below half the thickness of its upper wall and fitted from a right angle direction into a notch formed in the outer protrusion 14 of the shape material 10, Fourth
As shown in the figure, the lower part of the beam is brought into contact with the side wall 16 via a watertight packing 27, and a groove 26 formed in the earthen wall of the beam 25 communicates with the continuous groove 24.

Therefore, the condensed water generated on the inner surface of the panel 20 flows along the inner surface of the panel, collects in the groove 26 of the beam 25, and is discharged from the groove 26 through the continuous groove 24.

Also, in this embodiment, since there is a gap between the tightening protrusion 13 and the protrusion 14, the parts of the panel 20 that must be arranged at right angles to each other are assembled as shown in FIGS. 3 and 7. Even in such a case, the panel can be easily held by simply using the holding member 28.

Furthermore, in this embodiment, condensed water that has formed on the side wall 16 of the profile 10 is discharged through the guide groove 18.

Note that this invention is not limited to the above-described embodiment; for example, as shown in FIG.
9-10, one of the pair of protrusions 14 may also serve as a part of the tightening protrusion 13, or as shown in Fig. 11. Paired protrusions 1
The purpose of this invention was achieved by forming a communication hole on the inside of the hole 4, and by forming one of the protrusions diagonally as shown in FIG. It is also possible to arbitrarily change the shape, structure, etc. of each part within a range that does not deviate from the above.

Effects As detailed above, this invention has a tightening protrusion for tightening the holding member in the center of one side of the cylindrical member, and a packing that also serves as a gutter for condensed water to flow on both sides of the tightening protrusion. Since the bridge is provided with at least one pair of protrusions, the number of members required for assembling an arch-shaped or dome-shaped structure is small, and the assembly is very simple.
