DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arched roof structure.

[0002]

2. Description of the Related Art Conventionally, in various structures, a roof has been arched in order to secure a large indoor space or to have a characteristic in design.

For example, as this kind of roof structure, FIG.
As shown in FIG. 14, the horizontal member 11 and the diagonal member 12 are connected in a lattice shape via the connecting member 13 to form an arch-shaped frame, and a roof member (not shown) is attached to the surface thereof. Such a structure is generally known.

In this roof structure, for example, a horizontal member 11
Are formed in a rectangular shape, while the diagonal member 12 is formed in a trapezoidal shape as shown in FIG. Also, the connecting member 13
Has a configuration in which a horizontal member and an oblique member mounting flange extending in the axial direction are radially protruded from a peripheral surface of a shaft body. The oblique members 12 are connected in the Y-axis direction and the horizontal members 11 are connected in the X-axis direction to each other in the form of a lattice via the connecting member 13, so that the inclined members 12 are inclined at a constant curvature from the center in the Y-axis direction to both sides. Thus, an arched frame having a predetermined dimension in the X-axis direction is configured.

[0005] As shown in FIGS. 15 and 16, if necessary, the squares of the frame 10, that is, a pair of adjacent horizontal members 1.
In the quadrangular space formed by the first and diagonal members 12, the strength of the skeleton 10 is increased by attaching the reinforcing members 14 across the connecting members 13 opposed to each other.

[0006]

In many cases, a steel bar or an anchor is used as the reinforcing member 14, and the size of the reinforcing member 14 in the thickness direction of the frame 10 (the radius of curvature of the roof) is increased. , Etc., were rarely used.

That is, in the frame 10 in which the connecting members 13 are arranged toward the center of curvature O as shown in FIG. 14, that is, in the frame 10 in which the connecting members 13 are arranged in the radius of curvature direction, as shown in FIG. The interval between the lower ends is smaller than the interval between the upper ends of the adjacent connecting members 13. Therefore, for example, when a reinforcing member having dimensions in the axial direction of the connecting member 13 is to be attached across the connecting members 13 opposed to each other in the grid of the skeleton 10, as shown in FIG. The upper side 14a and the lower side 14b intersect and the reinforcing material 1
4 is twisted, which causes an excessive force to act on the reinforcing member 14. For these reasons, a plate or the like having dimensions in the thickness direction of the skeleton 10 has hardly been used as the reinforcing member 14.

However, in a concrete roof structure, it is more advantageous in terms of strength to use a reinforcing material such as a plate having dimensions in the thickness direction of the frame than to use a conventional reinforcing material such as a bar. In addition, the space divided by the reinforcing material can be used as a space for arranging lighting, etc., and it has high utility value, and in terms of design, using such reinforcing material gives a sense of unity as a whole Is often advantageous. Therefore, a structure that can use a plate having dimensions in the thickness direction of the skeleton as a reinforcing material is desired.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and a reinforcing material having a dimension in a thickness direction of a frame (a radius of curvature of a roof) is used as a reinforcing material for an arched roof structure. The purpose is to provide a roof structure that can be used.

In this way, the entire structure is formed in a lattice shape, and the horizontal member and the diagonal member are connected in the width direction via a connecting member extending in the radius of curvature direction, so that the upper surface and the lower surface are peripheral from the center in the width direction to the periphery in the width direction. In the roof structure in which the frame is formed so as to have a downwardly inclined surface on the side, the curvature radius direction extends across diagonally opposed connecting members among the connecting members corresponding to one square of the frame. A reinforcing member having a thickness is provided on the connecting member. The reinforcing member includes a reinforcing member body having a base end attached to each connecting member, and a connecting member for connecting the distal ends of the reinforcing member body to each other. To the top Relative position distal attachment portion corresponding to the inclination of the reinforcing material body caused by the relationship of the opposed coupling member is made provided.

According to this structure, in one square of the frame, that is, in a rectangular space formed by a pair of adjacent horizontal members and diagonal members, the reinforcing member main bodies attached to the opposing connecting members are different. Even if the reinforcing member main bodies are twisted by being inclined in the direction, the respective reinforcing member main bodies are connected to each other while maintaining the twisted relation via the connecting member. Therefore, even though the reinforcing member having a thickness in the radius of curvature direction is employed, no excessive force acts on the entire reinforcing member.

According to a second aspect of the present invention, in the roof structure according to the first aspect, the distal end corresponding to the four reinforcing member main bodies attached to the connecting member at the connecting member corresponding to one square of the skeleton. An attachment portion is provided.

According to this structure, the reinforcing member bodies attached to the four connecting members corresponding to one square of the frame can be integrally connected by one connecting member, whereby the cross-shaped reinforcing member can be connected. It is possible to improve the strength of the skeleton by configuring.

According to a third aspect of the present invention, in the roof structure, a plurality of diagonal members extending in the width direction and a plurality of horizontal members extending in a direction orthogonal to the width direction on a plane are connected to each other, so that the entire structure is in a lattice shape. And the horizontal and diagonal members are connected in the width direction via a connecting member extending in the radius of curvature direction, whereby the upper surface and the lower surface are inclined from the center in the width direction to the peripheral side in the width direction. In the roof structure in which the skeleton is formed such that a reinforcing material having a thickness in the radius of curvature direction is provided across the diagonally opposed connecting members among the connecting members corresponding to one square of the skeleton. The reinforcing member is attached at both ends to a mounting portion of the connecting member, and the mounting portion is connected so as to prevent twisting of the reinforcing member caused by a relative positional relationship between the opposing connecting members. It is made provided obliquely with respect to the axial direction of the member.

According to this structure, while the reinforcing member having a thickness in the radius of curvature direction is employed, the reinforcing member itself does not twist.

According to a fourth aspect of the present invention, in the roof structure according to the third aspect, a reinforcing member body whose base end is attached to the opposing connecting member and a distal end of the reinforcing member body are connected to each other. The reinforcing member is constituted by a connecting member, and the connecting member is provided with tip attachment portions corresponding to four reinforcing member bodies attached to the connecting member corresponding to one square of the skeleton. It is.

According to this structure, the reinforcing member main body can be attached to each of the four connecting members corresponding to one square of the skeleton, and can be integrally connected by one connecting member. It is possible to improve the strength of the skeleton by configuring.

As shown in FIG. 3 and FIG. 3, the reinforcing member 24 is a reinforcing member main body 32 (FIG. 4) attached to each of four connecting members 23 corresponding to one square of the skeleton 20.
And only one connecting member 33 for connecting the reinforcing member bodies 32 to each other.

The reinforcing member main body 32 is composed of a pair of unit reinforcing member main bodies 32a made of a plate material such as a steel plate.
The unit reinforcing member main body 32a is formed in a trapezoid in which the upper side dimension is slightly longer than the lower side dimension, and the side (left side in the figure) serving as a portion to be attached to the connecting member 23 is inclined. In addition, a pair of mounting holes 34 corresponding to the mounting holes 29 of the flange 28 are formed on the inclined side portions on the left and right sides, and the flange 37 of the connection member 33 is formed on the other side. A pair of mounting holes 35 corresponding to the holes 38 are formed in a line in the upper and lower rows, respectively, and the row is formed in parallel with the left and right sides.

The connecting member 33 has a configuration in which four flanges 37 for attaching a reinforcing member main body projecting radially are provided on each side surface of a square cylindrical shaft body 36 made of a steel pipe or the like. As shown in the figure, each flange 37 is inclined by a predetermined angle θ with respect to the axial direction of the shaft 36, and the flanges 37 adjacent in the circumferential direction are inclined in different directions as shown in FIG. Is provided. Such a flange 3
The inclination angle θ and the inclination direction of 7 will be described later in detail, but are determined corresponding to the angle and the direction according to the inclination of each reinforcing member main body 32 attached to the connecting member 23 corresponding to one square of the skeleton 20. ing. Each flange 37 has a pair of upper and lower mounting holes 38 for mounting the reinforcing member main body.

The frame 20 is constructed by connecting the horizontal member 21 and the diagonal member 22 configured as described above sequentially through a connecting member 23, and attaching a reinforcing member 24 over the connecting member 23. Have been.

More specifically, as shown in FIGS. 1 to 4, the horizontal member 21 is arranged in one axial direction (hereinafter referred to as X-axis direction).
However, the diagonal members 22 are sequentially connected in the form of a lattice via connecting members 23 in a direction orthogonal to the X-axis direction on a plane (hereinafter, referred to as a Y-axis direction), and the reinforcing member body 3
The two side members on the side of inclination 2 are attached, and the distal end portions of four reinforcing member main bodies 32 corresponding to one square of the frame constituted by a pair of adjacent horizontal members 21 and diagonal members 22 are connected by connecting members 33. The frame 20 is configured by being connected to each other.

Horizontal member 21, diagonal member 22, and reinforcing member main body 32
The connection between the connecting member 23 and the flanges 26, 27, 28 of the connecting member 23 is performed by using the unit horizontal member 21a and the unit diagonal member 22.
a and the mounting holes 29 of the flanges 26, 27, 28 and the mounting holes 3 of the respective unit materials.
It is performed by tightening and fixing with bolts and nuts through 0, 31, and 34. Similarly, the connection between the reinforcing member main body 32 and the connection member 33 is performed by each flange 37 of the connection member 33.
Is sandwiched between the unit reinforcing material main bodies 32a, and is tightened and fixed with bolts and nuts through the mounting holes 38 of the flange 37 and the mounting holes 35 of the unit reinforcing material main body 32a.

In the skeleton 20 constructed as described above, since the diagonal members 22 are trapezoidal as described above, the diagonal members 22 are sequentially connected to each other, as shown in FIG. In addition, the lower surface becomes an inclined surface which is inclined downward at a constant curvature from the center in the Y-axis direction to both sides thereof, whereby the frame 20 has an arch shape.

By the way, in such a structure of the skeleton 20, as shown in FIG.
Since the distance between the lower ends of the connection members 23 extending toward the center of curvature O of 0 and adjacent in the Y-axis direction is smaller than the distance between the upper ends thereof, when the reinforcing member 24 is attached, one square of the skeleton 20 is used. Diagonally opposed connecting members 23
As shown in FIG. 6 (lower diagram), the reinforcing member main bodies 32 attached to each other are inclined in different directions from each other, and the connecting members 23 are twisted (the dashed line in FIG. 6 (lower diagram) indicates the upper side of the reinforcing member main body 32). And the broken lines indicate the lower sides of the reinforcing member main body 32, respectively). However, in the reinforcing member 24, each flange 37 of the connection member 33 is provided at the inclination angle θ and the inclination direction corresponding to this angle and the inclination direction.
Four reinforcement bodies 32 corresponding to one square of the skeleton 20
Among them, the opposing reinforcing member main bodies 32 are connected via the connecting member 33 while being inclined in different directions.

That is, in one grid of the frame 20 formed in a lattice shape, if a plate material or the like is to be mounted as a reinforcing material over the connecting members 23 opposed to each other, the reinforcing material is twisted as described in the prior art. And practical implementation is difficult. However, in the present embodiment, as described above, the reinforcing member 24 includes the four reinforcing member main bodies 32 attached to the respective connecting members 23 in one square of the skeleton 20, and the connecting member 33 that connects these members to each other. Further, by configuring the flange 37 of the connecting member 33 to be inclined at an angle and a direction corresponding to the inclination of each reinforcing member main body 32, a member having a thickness in a radius of curvature direction such as a steel plate is used as a reinforcing member. The strength of the frame can be increased.

According to the skeleton 20 having such a structure, not only is it advantageous in strength as compared with a conventional arch-type skeleton of this type using a reinforcing member made of a bar, but also the horizontal member 21 is provided over the entire skeleton. Alternatively, a large number of triangular spaces surrounded by the diagonal member 22 and the reinforcing member main body 32 are formed, and this space can be effectively used as an arrangement space for lighting and the like. Advantages such as a unity feeling can be obtained as a whole.

Next, a second embodiment of the present invention will be described.

FIG. 7 shows a main part of a roof frame to which the roof structure according to the second embodiment is applied. The skeleton 20a shown in this figure also has the same basic configuration as the skeleton 20 of the first embodiment, but includes a connecting member 23 and a reinforcing member 24.
The configuration is different in that a connecting member 23a and a reinforcing member 24a as described below are applied instead of the above. In the following description, the skeleton 2 of the first embodiment is used.
Members that are common to 0 are denoted by the same reference numerals and described.

FIGS. 8A and 8B schematically show a connecting member 23a used in the second embodiment. As shown in these figures, the connecting member 23a is also provided with flanges 26, 27, 28 for attaching the horizontal member 21, the diagonal member 22, and the reinforcing member main body 32 around the shaft body 25. However, in the connecting member 23a, the flange 26 for attaching the reinforcing member main body 32 is inclined by a predetermined angle θ ′ with respect to the center axis of the shaft body 25, and the flange 26 or 27
The configuration differs from that of the connecting member 23 in that the flanges 28 that are adjacent to each other in the circumferential direction with respect to the connecting member 23 are provided so as to be inclined in different directions. This inclination angle θ ′ is an angle and an inclination direction such that the reinforcing member main bodies 32 attached to the opposing connection members 23 in one square of the skeleton 20 do not have a twisted relationship, specifically, FIG. (Figure below)
, The reinforcing material main body 32
The angle and the inclination direction are the same as when each reinforcing member main body 32 is rotated using the upper side as a rotation axis such that the lower side (indicated by a broken line) and the upper side (indicated by a dashed line) coincide.

On the other hand, the reinforcing member 24a is also
And a connecting member 33 for connecting the reinforcing member main bodies 32 to each other. Although not shown in detail in the reinforcing member 24a of the second embodiment, the reinforcing member main body 32
Are formed in a rectangular shape and each flange 37 of the connection member 33 extends in the central axis direction of the shaft body 36, and the first
It is different from the reinforcing member 24 of the first embodiment in that it is not inclined with respect to the central axis as in the embodiment.

That is, in the first embodiment, each of the flanges 37 of the connecting member 33 is inclined at an inclination angle θ with respect to the shaft 36.
By tilting only, as shown in FIG. 6 (lower figure), the reinforcing member main bodies 32 in a twisted relationship in one square of the skeleton 20 can be connected to each other, but in the skeleton 20a of the second embodiment, Flange 28 of connecting member 23a
Is tilted with respect to the central axis of the shaft body 25 by the tilt angle θ ′, so that in one square of the skeleton 20, twisting does not occur between the reinforcing member main bodies 32 attached to the opposing connecting members 23. I have to. Therefore, the connecting member 3
3, the configuration is such that each flange 37 is not inclined with respect to the central axis of the shaft 36.

In the frame 20a according to the second embodiment as described above, similarly to the frame 20 according to the first embodiment, a member having a thickness in the radius of curvature direction, such as a steel plate, is used as a reinforcing member to strengthen the frame. Therefore, an arched roof that is advantageous in terms of strength or design can be obtained.

Incidentally, the skeleton 20a of the second embodiment is used.
Then, in one square of the frame 20a, the reinforcing member main body 3 attached to the opposing connecting member 23a as described above.
Since the two members 2 do not have a twisted relationship with each other, for example, the connecting members 2 facing each other using one sheet material as a reinforcing material.
Even if the reinforcing member is attached over 3a, the reinforcing member is not twisted.

Therefore, for example, as a modification of the second embodiment, as shown in FIG. 9, a reinforcing member 24b made of only a plate material such as a steel plate is provided, and
It is also possible to configure the skeleton 20b to be attached over three. In this case, the reinforcing member mounting flange 28 is not required except for the connecting member 23a to which the reinforcing member 24b is attached. Therefore, these connecting members include the connecting member 23a in which the reinforcing member mounting flange 27 is omitted. 23b may be used.

According to such a frame 20b, the reinforcing member 2
Since 4b is made of only a plate material such as a steel plate, the structure is advantageous when the structure of the skeleton 20b is simplified or when it is not necessary to attach a cross-shaped reinforcing member such as the skeleton 20a or the skeleton 20b in terms of strength. Become.

The skeleton 2 of the first and second embodiments is described.
Reference numerals 0, 20a, and 20b are application examples of the roof structure according to the present invention, and the specific configuration can be appropriately changed without departing from the gist of the present invention.

For example, the frames 20, 20 of the above embodiment
In FIGS. 1A and 1B, the horizontal member 21 is made of a plate material such as a steel plate.
A horizontal member 40 assembled in a truss shape as shown in FIG. 0 may be adopted, or a horizontal member 41 composed of a pair of upper and lower rod members 41a may be adopted as shown in FIG. Good. The same configuration may be adopted for the diagonal member 22 or the reinforcing member main body 32 of the reinforcing member. Further, the configuration of the connecting members 23, 23a and 23b and the connecting member 33 of the reinforcing material are not limited to those of the above-described embodiment, and may be appropriately selected so as to obtain a desired skeleton. For example, in the first embodiment, as shown in FIG. 5, the upper end of the flange 37 is located at an intermediate position in the width direction of each surface of the connection member 33 (an intermediate position in the horizontal direction or the vertical direction in FIG. 5). Although the connection member 33 is formed with the flange 37, the flange 37 may be provided such that, for example, the middle portion in the vertical direction of the flange 37 is located at the middle position in the width direction of each surface of the connection member 33. Similarly, in the second embodiment, as shown in FIG. 8, the upper end of the flange 28 is located at an intermediate position between the flange 26 and the flange 27 (in the horizontal direction in FIG. 8B) in the connecting member 23a. Although the flange 28 is formed on the shaft body 25 on the basis of the upper end, for example, the flange 28 may be provided such that the vertical intermediate portion of the flange 28 is located at an intermediate position between the flange 26 and the flange 27.

In the above embodiment, the arched frame 20 is formed by sequentially connecting the trapezoidal diagonal members 22 made of a plate material such as a steel plate in the Y-axis direction via the connecting member 23. For example, a frame may be formed by sequentially connecting arc-shaped diagonal members 22 'as shown in FIG. According to such a framework, a smoother arched roof can be obtained.

Further, in the above embodiment, the frames 20, 2
0a is an arch-shaped roof structure having a constant curvature. Of course, the roof structure of the present invention has a skeleton in which the curvature changes,
For example, the present invention can be applied to a skeleton having a small curvature at a central portion in the Y-axis direction and a large curvature at a peripheral portion.
