[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arch-shaped building structure constructed by using, for example, a large deck plate, a keystone plate, or a wavy plate having a large section modulus such as a deck plate.

[0002]

2. Description of the Related Art Generally, an arch-shaped building structure used as a snow shelter, a cushion shelter, or the like is constructed by attaching a steel plate such as galvanized iron to a frame made of steel frame or the like.

On the other hand, the applicant of the present patent application is, for example,

Proposed an arch-shaped building structure composed of wavy plates with large section modulus, such as large deck plates.

According to such an arch-shaped building structure,
The manufacturing cost and the number of manufacturing steps can be reduced as compared with the conventional arch-shaped building structure, and sufficient strength can be secured without using a steel frame or the like.

However, when the load condition becomes extremely severe, for example, when the span of the arch-shaped building structure becomes extremely large, the strength needs to be reinforced by some method.

As this reinforcing method, for example, as shown in FIG. 8, a method using an H rope can be considered. Note that FIG.
[Fig. 3] is a cross-sectional view of a part of the arch portion as seen from above, cut.

In the figure, reference numeral 1 is a wall member forming an arch portion. The wall member 1 is composed of, for example, a large deck plate.

Reference numeral 2 is a reinforcing member for reinforcing the arch portion. The reinforcing member 2 is formed of H rope, and the wall member 1
On the other hand, it is attached so as to extend from the ground side to the ceiling side.

According to this structure, since the reinforcing member 2 functions as a pillar, the strength of the arch portion can be increased.

However, in such a configuration, since the wall member 1 and the reinforcing member 2 are completely different in shape, there is a problem in that when they are transported to the construction site of the arch-shaped building structure, the transportation efficiency is lowered. .

Further, since the shapes of the wall member 1 and the reinforcing member 2 are completely different from each other, the reinforcing member 2 is conspicuous, and the internal appearance of the arch portion is impaired.

Further, in order to secure the desired strength, it is usually necessary to use, as the reinforcing member 2, a large H rope having a height H2 which is more than twice the height H1 of the large deck plate.

As a result, the amount of protrusion of the reinforcing member 2 from the wall member 1 increases, and the internal appearance of the arch portion is impaired.

[0014]

As described above, in the case where the arch portion constituted by the wavy plate having a large section modulus is reinforced by the H rope, there is a problem that the transport efficiency of the structural member is lowered. However, there is a problem in that the internal beauty of the arch portion is impaired.

Therefore, an object of the present invention is to provide an arch-shaped building structure capable of ensuring sufficient strength without lowering transportation efficiency and internal aesthetics.

[0016]

To achieve the above object, in the present invention, a corrugated member having a large section modulus and curved in the corrugating direction is used as the reinforcing member.

The reinforcing member is attached to the wall member, which is also formed in a wave shape, so that one crest and the other trough face each other and extend from the ground side to the ceiling side.

[0018]

According to the above structure, the box-shaped reinforcing column is eventually formed by the mutual connection of the wall member and the reinforcing member. As a result, the strength of the arch portion can be sufficiently increased without using H steel that is heavy and difficult to bend.

In this case, since the wall member and the reinforcing member have the same shape, when they are transported to the construction site of the structure, they can be transported in a stack. Thereby, even if the reinforcing member is provided, it is possible to prevent the transport efficiency of the structural member from being lowered.

Since the wall member and the reinforcing member have the same shape, even if the reinforcing member is provided, the reinforcing member can be made inconspicuous. As a result, even if the reinforcing member is provided, the internal appearance of the arch portion will not be impaired.

Further, since the box-shaped column has high strength, even if the reinforcing member is made of a member having the same height as the wall member, it is made of an H rope having a height twice that of the wall member. Can obtain almost the same strength as.

As a result, the amount of protrusion of the reinforcing member from the wall member can be reduced, so that it is possible to prevent deterioration of the internal appearance of the arch portion due to the provision of the reinforcing member.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the following description, the present invention will be described in detail, for example, in the arch-shaped building structure described in Japanese Utility Model Application No. 1-100750 filed by the applicant of the present application for utility model registration on August 29, 1991. The case of application to the above will be described as a representative.

FIG. 1 is a perspective view showing the external structure of this arch-shaped building structure.

In the figure, 10 is an arch portion formed in an arch shape. Reference numerals 22 and 23 are bases for supporting the arch portion 10 on the ground 24.

The arch portion 10 includes two curved bodies 11 and 12.
At the ceiling by connecting members 13 and 14.

Flange 20 and 21 are provided at the ends of the curved bodies 11 and 12 on the ground 24 side.

The arch portion 10 includes the flanges 20 and 21.
Is fixed to the foundation bases 22 and 23 by a fastener 25 composed of, for example, a bolt and a nut, so that it is positioned on the ground 24.

FIG. 2 is a plan view of the arch-shaped building structure of FIG. 1 seen from above.

As shown in the drawing, each of the curved bodies 11 and 12 is formed by connecting a plurality of wavy wall members 15 in the corrugation direction X1.

In this case, each wall member 15 has a corrugated direction X1.
Is arranged so as to overlap with the adjacent wall member 15 at the end portion thereof.

Then, in the overlapping portion 16 caused by this overlapping arrangement, the adjacent wall members 15 are connected to each other by the fastener 1.
7 are linked together.

As a result, the curved bodies 11 and 12 are secured in strength continuity in the corrugation direction X1.

Each wall member 15 is composed of, for example, a large deck plate. In this case, each large deck plate is R-bent in a direction orthogonal to the corrugation direction X1, as shown in FIG.

A plurality of connecting members 13 are arranged on the outer surface of the arch portion 10 in the corrugation direction X1.

In this case, the connecting members 13 are adjacent to each other.
Between the two overlapping portions 16, the two curved bodies 11, 1
It is arranged so as to straddle two.

Similarly, the plate member 14 also has the arch portion 1
On the inner surface of 0, a plurality are arranged in the corrugation direction X1.

In this state, the two connecting members 13 and 14 facing each other are connected by the fastener 18 via the curved bodies 11 and 12.

As a result, the two curved bodies 11 and 12 are
The large deck plates 15 are connected in the length direction X2 while maintaining strength continuity.

FIG. 3 is a side sectional view of the arch-shaped building structure taken along the line L1-L2 in FIG. 2 and viewed in the direction of the arrow.

As shown in the figure, the connecting members 13 and 14 are formed in a trapezoidal wave shape in cross section so as to fit into the wall member 15.

Such connecting members 13 and 14 can be formed, for example, by R-bending, cutting, and pressing a large deck plate.

Here, the pressing process is performed by connecting members 13 and 1
4 is done so that the wall member 15 fits perfectly.

That is, the large deck plate has a trapezoidal corrugated cross-sectional shape and a large wall thickness, as will be described later.

Therefore, if the connecting members 13 and 14 are formed only by the R bending process and the cutting process of the large deck plate, when the connecting members 13 and 14 are overlapped with the wall member 15, only the wall thickness of the wall member 15 is increased. , The ridges of the wall member 15 and the connecting members 13, 14 do not match.

Then, the connecting member 1 is formed by pressing.
The waveforms of 3 and 14 are deformed so that the peaks of both are aligned.

Further, the corrugation direction X of each connecting member 13, 14
The width of 1 is the corrugation direction X1 of the wall member 15 by cutting.
Is set to be smaller than the width of.

This means that if the widths of both are the same, the two wall members 15 and the two connecting members 1 at the overlapping portion 16 are formed.
This is because it is necessary to fasten a total of four members 3, 14 and fastening is difficult.

A plurality of the flanges 20 and 21 are provided for each large wall member 15, as shown in FIG.

In this case, the flanges 20 and 21 are attached to the end of the corresponding wall member 15 on the ground 24 side, for example, by welding or the like.

The above is the schematic structure of the arch-shaped building structure described in Japanese Utility Model Application No. 1-100750.

The structure of the large deck plate will be described before describing the structure which characterizes the present invention.

FIG. 4 is a side view showing the shape of the large deck plate and the dimensions of each part.

As shown, the large deck plate has a trapezoidal corrugated cross-sectional shape. In this case, each corner of the trapezoidal wave has some R. However, in FIG. 3 described above, this R is not shown in order to simplify the drawing. This also applies to the following drawings.

Height of mountain of large deck plate (H in FIG. 8)
1) is set to 100 mm. Also, the wall thickness is
At present, five types are set in the range of 2.7 mm to 6.0 mm.

Further, the width in the corrugation direction X1 is 570 mm.
Is set to Of this width, for example, 70 mm is assigned to the overlapping portion 16. Therefore,
In this case, the effective width of the large deck plate in the corrugation direction X1 is 500 mm.

The above is the configuration of the large deck plate 15. The above-mentioned dimensions are based on the Japanese Industrial Standards ((JI
S).

Next, the constitution characteristic of the present invention will be described.

FIG. 5 is a front view of the arch-shaped building structure shown in FIG. 1 as viewed from the end surface side.

In the figure, 31 and 32 are arch portions 10.
Is a reinforcing member for reinforcing the strength of the.

The reinforcing member 31 has a curved shape similar to that of the wall member 15. In such a configuration, the reinforcing member 31 is arranged so as to extend from the flange 20 to the vicinity of the connecting member 14.

In this state, the reinforcing member 31
Is attached to the wall member 15 of the bending body 11 by a fastener 33.

Similarly, the reinforcing member 32 is arranged so as to extend from the flange 21 to the vicinity of the connecting member 14,
It is attached to the wall member 15 of the bending body 12.

As shown in FIG. 3, a plurality of reinforcing members 31 are arranged in the corrugated direction X1 so as to be separated from each other by a predetermined distance. In the figure, every other one of the wall members 15 is a reinforcing member 3.
The case where 1 is provided is shown.

Although not shown in the figure, the reinforcing member 32
Also, a plurality of them are arranged at predetermined intervals in the corrugated direction X1.

FIG. 6 shows the arch-shaped building structure of FIG.
Is a cross-sectional view taken along line L3-L4 and seen in the direction of the arrow.

As shown in the figure, the reinforcing member 31 is the wall member 15
Similarly, the cross section has a trapezoidal wavy shape.

Such a reinforcing member 31 is formed, for example, by bending and cutting a large deck plate.

The reinforcing member 31 is attached to the wall member 15 so that one peak and the other valley overlap each other.

That is, now, the wall member 15 and the reinforcing member 31
At, in the center line La, Lb parallel to the corrugation direction X1, the portion protruding toward the outside of the arch portion 10 is a mountain,
The part that projects inward is the valley.

When the peaks and valleys of the waveform are defined in this way,
The wall member 15 of FIG. 6 has a mountain 151 for one cycle at the center.
Has a valley 152 for one cycle on each side,
153, and is further provided with peaks 154 and 155 for approximately half cycles on both sides thereof.

Similarly, the reinforcing member 31 is set to have a valley 311 for one cycle in the central portion and peaks 312, 313 for approximately half cycles on both sides thereof.

Such a reinforcing member 31 has, for example, the wall member 15 in the corrugated direction X1 at the center of the mountain 151.
It can be obtained by cutting in a direction orthogonal to.

In such a set state, the reinforcing member 3
No. 1 is attached to the wall member 15 so that the valley 311 faces the crest 151 of the wall member 15.

In this case, the fastening position by the fastener 33 is
Overlap of mountain 152 and valley 312 and mountain 153 and valley 313
Are set in the overlapping part of.

Due to the above-described combined structure of the wall member 15 and the reinforcing member 31, a box-shaped column having a hexagonal cross section is formed. In general, a box-shaped column has a very high strength, and therefore, by forming such a column, the strength of the bending body 11 can be increased.

Although not described in detail, the reinforcing member 32
Also has the same shape as the reinforcing member 31, and also the reinforcing member 3
It is attached to the wall member 15 in the same manner as 2. As a result, the strength of the bending body 12 is increased by the reinforcing member 32.

According to this embodiment described in detail above, since the reinforcing members 31 and 32 are constituted by the large deck plate like the wall member 15, when the reinforcing members 31 and 32 are transported, the wall member 15 is carried. It can be stacked and transported.

As a result, it is possible to prevent the transport efficiency from being lowered by transporting the reinforcing members 31 and 32.

Further, since the reinforcing members 31 and 32 have the same shape as the wall member 15, even if the reinforcing members 31 and 32 are provided, they do not stand out. Thereby, the reinforcing member 3
Even if 1, 32 are provided, the internal aesthetics of the arch portion 10 is not impaired.

Further, since the box-shaped column has a very large strength, even if the reinforcing members 31 and 32 are formed by a large deck plate having the same size as the wall member 15, the reinforcing member is not included in the wall member 1.
It is possible to secure almost the same strength as in the case of using the H rope having the height of 5 times.

As a result, the reinforcing member 3 from the wall member 15
Since the projecting amounts of 1 and 32 can be reduced, it is possible to prevent deterioration of the internal aesthetics of the arch portion 10 due to the provision of the reinforcing members 31 and 32.

FIG. 7 is a sectional view showing the structure of the main part of the second embodiment of the present invention. FIG. 7 is a view showing a sectional structure of the bending body 11 in the same manner as FIG.

In this embodiment, the wall member 15 is arranged in the opposite manner to the previous embodiment.

According to this arrangement, the wall member 15
Is one trough 156 for one cycle, two peaks 157, 158 for one cycle, and two troughs for half cycle 1
Will have 59,160.

Therefore, in this case, two mountains 157,
At 158, it is possible to form pillars as described above.

Therefore, in this embodiment, one wall member 15 is formed by using the reinforcing member 41 having the same width as the wall member 15.
In, the two columns are formed.

That is, as shown in FIG. 7, the reinforcing member 41 has one crest 411 for one cycle, two troughs 412 and 413 for one cycle, and two crests 4 for half a cycle.
It has 14,415.

Then, the reinforcing member 41 has the valleys 412, 41.
3 are attached to the wall member 15 so as to face the peaks 157 and 158 of the wall member 15, respectively.

In this case, the ridges 41 on both ends of the reinforcing member 41
4, 415 are fixed to the wall member 15 by fasteners 17 at the overlapping portions 16 of the adjacent wall members 15.

The central mountain 411 of the reinforcing member 41 is
It is fixed to the valley 156 of the wall member 15 by the fastener 33.

In this structure, the reinforcing member 41 is formed by R-bending the large deck plate in the direction opposite to the wall member 15.

According to this embodiment described in detail above, since two columns can be formed for one wall member 15, if the reinforcing members 41 are arranged at the same intervals as in the previous embodiment, The reinforcing capacity can be made higher than in the previous embodiment.

On the contrary, when the same reinforcing capacity as that of the previous embodiment is required, the arrangement interval of the reinforcing members 41 can be made wider than that of the previous embodiment.

Although two embodiments of the present invention have been described above, the present invention is not limited to such embodiments.

For example, in the above embodiment, the case where the reinforcing members 31, 32 and 41 are attached to the wall member 15 every other one has been described.

However, the arrangement intervals of the reinforcing members 31, 32, 41 are determined by the load conditions, and are not necessarily limited to such arrangement intervals.

Further, in the above embodiment, the reinforcing members 31 and 3 are
A case has been described in which 2, 41 are stopped before the connecting member 14.

However, in the present invention, this may be further extended or, conversely, may be shortened, depending on the load condition.

Further, in the above embodiment, the reinforcing members 31 and 3 are
The case where the wall member 15 to which 2 and 41 are attached and the other wall member 15 are constituted by corrugated plates having the same section modulus has been described.

However, the wall member 15 to which the reinforcing members 31, 32, 41 are attached is reinforced by the reinforcing members 31, 32. Therefore, the wall member 1 may be configured by a corrugated plate having a smaller section modulus than the corrugated plates constituting the other wall members 15.

In the above embodiment, the case where the present invention is applied to the arch-shaped building structure described in Japanese Patent Application No. 1-100750 has been described.

However, the present invention may be applied to the arch-shaped building structure described in other utility model registration applications as described above.

In addition to this, it goes without saying that the present invention can be variously modified and implemented without departing from the scope of the invention.
