Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is suitable exclusively for buildings with a student span of 1.
Concerning a new composite membrane structure.

(Prior Art and Problems to be Solved by the Invention) At present, the forms of membrane structures that are generally popular include air membrane structures, suspension membrane structures, and frame membrane structures.

Among these, the most common type of the above-mentioned framework membrane is one in which a membrane material is attached between arch materials, and these are basically classified into the following two types.

One is a loss arch type (cross arch type) as shown in FIG. 22, and the other is a parallel arch type (Nm row arch type) as shown in FIG.

In the case of the above-mentioned cross arch type, since the arch members 1 are arranged in an intersecting manner, stability is good, but there is a drawback that the shape is standardized and changes in design cannot be expected.

Furthermore, since each membrane material 2 disposed between the arch materials 1 needs to be formed into a triangular shape, there is a problem in that the fit is lost from a manufacturing standpoint.

On the other hand, in the case of the parallel arch type, each arch material l
are arranged independently and parallel to each other, and in order to ensure stability, either a connecting material is inserted between each arch material 1 below the membrane material 2, or the arch material 1 itself is made into a highly self-supporting three-dimensional truss. There are 11 letters.

However, if a connecting material is provided, the connecting material will be exposed on the indoor side of the lower part of the membrane material 2, so the expression of lightness and elasticity, which are the characteristics of a curved membrane surface, will be realized. There is a drawback that it cannot be done.

In addition, a common drawback of both types is that when a tie is placed to prevent the arch material l from buckling, the tie and the membrane material 2 above it may come into contact during snowfall or wind blowing. In order to avoid this, restrictions are placed on the spacing between the arch members 1.

This has led to the problem that it is no longer possible to form a membrane concave surface with a wide width and a deep sag (large mass ratio) that can provide an effective tension resistance system as a suspension membrane.

In addition, FIGS. 24 to 26 show examples of conventional arch-shaped framework membrane structures, and FIGS. 24(a) and 24
Figure (b) shows an example in which the arch material l is a funeral material, and the second
5 [71(a) and FIG. 25(b) show an example in which each arch material is formed as a plane truss, and FIG. 26(a) and FIG. 26(b) show an example in which each arch material I is formed as a plane truss. An example formed as a space truss is shown.

In the figure, 1 is an arch material, 2 is a membrane material, and 3 is a connecting material.

The present invention was developed in view of the above-mentioned conventional problems, and an object of the present invention is to provide a novel arch-shaped suspension membrane structure that combines the advantages of membrane structures.

(Means for Solving the Problems) In order to achieve the above object, in the arch-type suspension membrane structure according to the present invention, each arch member is arranged substantially parallel or radially, and the space between each arch member is A holding cable is provided on the membrane material in the same direction as each arch material at an intermediate position between the arch materials, and a holding cable is provided on the membrane material in the same direction as each arch material at an intermediate position between the arch materials. It is characterized by comprising a connecting member that connects to the.

(Example) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

13 is a sectional view taken along line 13.

The arch-shaped suspension membrane +MTi according to this example is
Arch material 10 and membrane material! 1, a holding cable 12, and a connecting member 13.

In this embodiment, the arch members 10 are installed in parallel to each other in the inter-beam direction, showing an example of a floating arch type.

Further, in this embodiment, each arch member 10 is formed of a single round steel pipe.

Further, the membrane material 11 is disposed between each arch material 10, and the holding cable I2 is connected to the membrane material 11 in parallel with each arch material in the same direction at an intermediate position 11'2 between each arch material 10. The membrane material 11 is provided with a predetermined tension.

Further, the connecting member I3 connects each of the arch members 10 to the Japanese tiles at a position above the first mock member 11.

In this embodiment, the connecting member 13 is made of a steel rod or cable material, and is used as a tensile member.

Further, in FIGS. 4 and 5, 14 is a lower structure that supports the roof portion.

This embodiment having such a configuration has the following effects.

(+) The connecting material 13 can be used as a multifunctional material such as an out-of-plane buckling material for the arch material 10, a fall prevention material, and a supporting material for out-of-arch stress caused by an unbalanced force from the membrane surface.

(2) The exterior has a mechanical design with the arch material 10 and the connecting material 13. On the other hand, since the connecting material is not visible from the indoor side unlike the conventional example, the white version has a membrane surface with sufficient curvature on the ceiling. By arranging the membrane, it is possible to express a soft and light membrane space unique to the membrane, such as a conventional suspension membrane structure or an air membrane traverse.

(3) Unlike the conventional example, since a large sag on the membrane surface can be removed regardless of the tie material 13, it is expected that the membrane material 11 will exhibit an effective tension resistance system when loaded with snow on treetops and when the wind blows down.

(4) A holding cable 12 is placed between each arch material 10 to apply tension to the membrane surface and restrain it, so when the wind blows up, the membrane surface is slightly raised upwards as shown by the imaginary line in Figure 1. The membrane material 11 and the connecting material 13 do not come into contact with each other.

Therefore, the width of the membrane material 11 between each arch material 10 can be increased, and rationality in manufacturing and construction can be obtained.

(5) Since steel rods or cables are used as tension members as the connecting members 13, by introducing an appropriate prestress force in advance, it is possible to increase the spacing between the arch members 10, reducing the weight of the frame. , economic efficiency can be ensured.

In addition, the arch material 10 and the connecting material 13 are determined depending on the scale and load (snow planting).
Various materials and types can be selected depending on the conditions, and as the arch material 10, in addition to round steel pipes, single materials such as square steel pipes and laminated wood, and torsion applied from the membrane material 11 such as in three-dimensional truss etc. A vine used by villages that are resistant to moments.

Further, as the connecting member 13, in addition to steel rods and cables, shaped steel such as a vibrator can be used as a compressed material.

Further, FIG. 9 shows a fourth embodiment of the present invention, and this embodiment is an example in which a pair of arch members 1O110 and a connecting member 13 form a ladder-like frame member.

Furthermore, FIGS. 10 and 1f show a fifth embodiment of the present invention, and FIGS. 12 and 13 show a sixth embodiment of the present invention.

Therefore, in the fifth embodiment, the arch members 10 are arranged in a Q-L shape around the compression ring member 17 formed in the center, and the six holding cables 12 are also arranged between the arch members 10. They are arranged radially from the central compression ring member 17 at an intermediate position toward the fixing portion 18 on the outer periphery. Further, the connecting members 13 are arranged in an annular shape.

In addition, in the sixth embodiment, the arch material I distributed in parallel
This is an example in which the connecting members 13 as well as O are arranged in an arch shape as a whole, and the connecting members 13 are used as compressed members.

Next, FIG. 14 shows a seventh embodiment of the present invention. In this embodiment, the membrane material 12 is suspended downward from a plurality of locations on each arch material 10 by a lifting member 19 such as a strut cable.
