DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure roof, and more particularly to a roof structure using a film-like roofing material.

[0002]

Generally, when performing an event outdoors, a temporary structure for blocking sunlight is installed. Since such a temporary structure is required to be easily installed and removed, a roof using a film-like roof material is usually installed. That is, the roof of the temporary structure is formed by attaching a film-like roof material to a frame obtained by assembling pipes.

[0003] When a roof is made of a film-like roof material, its appearance is very poor if the roof material is in a relaxed state. In addition, it may cause the roofing material to flutter when exposed to wind. For this reason, the roofing material must be completely stretched. In other words, the roofing material must be given a predetermined tension. Therefore, conventionally, the roof was erected as follows. That is, first, the roof is set at a predetermined height in a state where only the center portion of the roof material is fixed. Next, pull the edge of the roofing material from all directions,
Finally, the peripheral edge of the roofing material is fixed to the frame so that the tension is maintained. This completes the construction of the roof.

[0004] However, in the case of such a roof having a conventional structure, it takes a lot of time to construct the roof, particularly to extend the roof material. Above all, the last work to fix the roof material periphery must be done with tension applied to the roof material,
Great effort is required. Therefore, an object to be solved by the present invention is to provide a roof structure capable of easily setting a roof material to a completely expanded state when a roof is erected. In particular, it is an object of the present invention to provide a roof structure capable of simultaneously expanding a roof material and applying tension to the roof material when the roof is erected.

[0005]

The object of the present invention is to provide a vertical member located on the center side of a roof, a base end side of which is rotatably connected to an upper end side of the vertical member, and a radial member centering on the vertical member. A plurality of shaft members, a bundle member provided so as to be displaceable with respect to the vertical member, one end side is rotatably connected to each of the shaft members, and the other end side is the bundle member. A plurality of shaft support members rotatably connected to the shaft member, and a film-like roof material whose edges are fixed to the front end side of the shaft body at predetermined intervals, and the bundle member is By displacing upward and increasing the opening angle between the adjacent shaft bodies, a roof structure configured so that the roof material is stretched, and between the upper end of the vertical member and the roof material. Is
A top crown member that is displaceable with respect to the vertical member is provided, and the top roof member is configured to be displaced upward so that a predetermined tension can be applied to the roof material to be expanded. It is solved by the characteristic roof structure.

[0006] In particular, the above-described problem is caused by a vertical member located on the center side of the roof, a base end side of which is rotatably connected to an upper end side of the vertical member, and which is radially arranged around the vertical member. A plurality of shafts, a bundle member provided so as to be displaceable with respect to the vertical member, one end side is rotatably connected to each of the shaft bodies, and the other end side is relative to the bundle member. A plurality of shaft support members rotatably connected,

A roof structure configured so that the roof material is stretched, wherein a top cap member displaceable with respect to the vertical member is provided between an upper end of the vertical member and the roof material. By displacing the top crown member upward, a predetermined tension can be applied to the roof material to be expanded, and the top crown member is
The roof structure is characterized in that the bundle member is configured to be displaced in accordance with a displacement in a certain range of the bundle member.

[0007] When the top crown member is configured to be displaced with the displacement of the bundle member in a certain range,
The following structure can be adopted. That is, the vertical member is formed in a tubular shape, and the lower portion of the top cap member is housed in the vertical member. Further, the bundle member is formed in an annular shape, and a bolt is inserted through the bundle member so that the head is positioned downward. Further, a nut is fixed to the lower end of the vertical member, and the bolt is screwed to the nut. Then, after the bundle member is displaced upward by rotating the bolt in the forward direction, and the tip of the bolt contacts the lower end of the crown member,
Further, by rotating the bolt in the forward direction, the top crown member can be configured to be displaced upward together with the bundle member.

In the present invention, a roof using a film-like roofing material has a special structure as described above. That is, by displacing the bundle member upward and increasing the opening angle between adjacent shafts, the roof member is configured such that the roof member is stretched, and a vertical member is provided between the upper end of the vertical member and the roof member. Is provided so that a predetermined tension can be applied to the roof material to be expanded by displacing the top crown member upward. This eliminates the need for a large amount of labor, such as the conventional technique, in which the peripheral edge of the roofing material is pulled from all directions and the peripheral edge of the roofing material is fixed to the frame so that the tension is maintained. Instead of this, it is sufficient to simply displace the top crown member upward, and by using the technology of the present invention, the roofing material can be easily brought into a completely expanded state when the roof is erected. become. Further, if the top crown member is configured to be displaced in accordance with a displacement (final displacement) in a certain range of the bundle member, it becomes possible to perform the expansion of the roofing material and the application of tension to the roofing material at one time. . As a result, the workability can be further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in more detail with reference to FIGS. 1 is an external view of a temporary structure in which a roof having a structure according to the present embodiment is erected, FIG. 2 is a cross-sectional view of the erected roof, FIG. 3 is a plan view of the erected roof, and FIG. FIG. 5 is a cross-sectional view of a main part of the roof showing a state immediately before the roofing material is completely expanded, and FIG.

The appearance of a temporary structure on which a roof having a structure according to the present embodiment (hereinafter simply referred to as a roof) is erected is as shown in FIG. As can be seen from the figure, the roof A is supported at a predetermined height by a total of four columns B. In the present embodiment, the roof A is configured from a total of six shafts described below so that the planar shape thereof is rectangular, and as described above, the roof A is mounted using the four pillars B in total. I support it. But, needless to say, roof A
Is not limited to that of the present embodiment. Therefore, the support B that supports the roof A
The number, the standing position, and further the method of supporting the roof A are appropriately selected according to the situation of the site where the structure is installed.

As shown in FIGS. 2 and 3, the roof A includes a vertical member 1, a plurality of shafts 2a to 2f, a bundle member 3, and a plurality of shaft support members 4a to 4 as main components.
f, and a film-like roofing material 5. Among them, the vertical member 1 is located at the center of the roof A, and in the present embodiment, a tubular member is used in order to store a lower portion of a later described crown member. The length of the vertical member 1 is
When erected, it does not hinder personnel working below it.

On the other hand, the bases of the shafts 2a to 2f are rotatably connected to the upper end of the vertical member 1. That is, the shafts 2 a to 2 f are radially arranged around the vertical member 1. However, since the planar shape of the roof A is rectangular as described above, the shafts 2a to 2f
Are not all the same length. Specifically, the shaft 2c
And the shaft 2f is shorter than the others.

Further, the bundle member 3 constituting the roof A together with the vertical member 1 and the shafts 2a to 2f is provided so as to be displaceable with respect to the vertical member 1. More specifically, the bundle member 3 is annular, and is connected to the vertical member 1 via a long bolt 6 that passes through itself. Although not described when the vertical member 1 was described earlier, a nut 7 is fixed inside the lower end side of the vertical member 1. The bolts 6 are screwed onto the nuts 7. Therefore, when the bolts 6 are rotated in the forward direction when the roof is erected, the bundle member 3 that is placed on the head 6 a is in a good shape.
Is displaced upward together with the bolt 6.

Next, regarding the shaft support members 4a to 4f, these shaft support members 4a to 4f
It serves to support the shafts 2a to 2f from below.
That is, one end side (upper end side) of the shaft support members 4a to 4f.
Is rotatably connected to each of the shaft bodies 2a to 2f. On the other hand, the other end sides (lower end sides) of the shaft supporting members 4 a to 4 f are rotatably connected to the bundle member 3. When the roof A is viewed from above, the shaft supporting member 4
Since a to 4f are hidden under the shafts 2a to 2f,
It does not appear in FIG. However, in practice, the shaft support members 4a to 4f correspond to the shaft members 2a to 2f, respectively (the shaft support member 4a corresponds to the shaft member 2a, the shaft support member 4b corresponds to the shaft member 2b,
..., The shaft support members 4f are radially arranged corresponding to the shaft 2f).

Further, the membrane-like roofing material 5 has a
The points are fixed to the tip ends of the shafts 2a to 2f.
In the present embodiment, a cloth material subjected to a water-repellent treatment is used as the roof material 5. In the present embodiment, a method of fastening the roofing material 5 is described. In the present embodiment, a plurality of locking pins (not shown) provided at the tip of each of the shafts 2a to 2f are provided. (Not shown). In other words, the peripheral edge of the roofing material 5 is fixed to the tip ends of the shafts 2a to 2f by positioning the locking pins in the locking holes. However, the fastening method of the roofing material 5 is not limited to such a method.

Generally speaking, when the roof A is installed, the bolts 6 are screwed onto the nuts 7 and then rotated in the forward direction. The member 3 is displaced upward. Thereby, the opening angle between adjacent ones of the shaft bodies 2a to 2f increases. That is, as shown in FIG. 4, the tip ends of the shafts 2a to 2f rise. As a result,
In the roof A having the above structure, the roof material 5 fixed to the shaft bodies 2a to 2f is extended. After this, roof A
Is installed at a predetermined height by using the above-mentioned support B, and finally reaches the erected state shown in FIG.

In the present embodiment, a top cap member 8 displaceable with respect to the vertical member 1 is provided between the vertical member 1 and the roof member 5.
(The amount of displacement is indicated by H in FIG. 2).
The top crown member 8 includes a cap-shaped portion 8a and a rod-shaped portion 8b. The cap portion 8a is located between the upper end of the vertical member 1 and the lower surface of the roofing material 5, and is in direct contact with the roofing material 5. On the other hand, as described above, the rod-shaped portion 8b is
Is housed inside. Therefore, in the roof A, a predetermined tension can be applied to the roof material 5 that is expanded by displacing the top crown member 8 upward.

Particularly, in the present embodiment, the top crown member 8 is configured to be displaced in accordance with a displacement (final displacement) of the bundle member 3 in a certain range. More specifically, as described above, the elongated bolt 6 is inserted through the bundle member 3 so that the head 6a is positioned below. Before the screw 6 is screwed into the nut 7 to the final position (in this embodiment, about several cm to several tens cm before reaching the final position), the tip of the bolt 6 contacts the lower end of the rod portion 8b of the top crown member 8. It comes into contact. In other words, the length of the vertical member 1, the bolt 6, and the rod-shaped portion 8 b of the top crown member 8 are set so that the bolt 6 and the rod-shaped portion 8 b of the top crown member 8 have the above-described relationship. By the way, initially, the bundle member 3 is displaced upward alone by rotating the bolt 6 in the forward direction. However, in the roof A having the above configuration, the tip of the bolt 6 is formed by the rod-shaped portion of the top cap member 8. When the bolt 6 is further rotated in the forward direction after contacting the lower end of the bundle member 8b, the top crown member 8
And displaces upward. Then, the central portion of the roofing material 5 to be expanded is lifted, and as a result, a predetermined tension is applied to the roofing material 5. Incidentally, the state immediately before completion of the tension application to the roofing material 5 when the top crown member 8 has risen to the vicinity of the final position is as shown in FIG. From this position, the bolt 6 is further rotated in the forward direction, and the top crown member 8 is rotated.
Is displaced upward to obtain the final state shown in FIG.

As described above, in the present embodiment, the roof A using the film-like roof material 5 has a special structure as described above. That is, the bundle member 3 is displaced upward, and the shaft body 2a
The roof A configured to extend the roofing material 5 by increasing the opening angle between the adjacent ones in ~ 2f
, A top cap member 8 that can be displaced with respect to the vertical member 1 is provided between an upper end of the vertical member 1 and the roof material 5, and the roof material is expanded by displacing the top cap member 8 upward. 5
Is configured so that a predetermined tension can be applied evenly. Therefore, it is unnecessary to perform a large amount of labor such as pulling the peripheral edge of the roofing material from all directions and fixing the peripheral edge of the roofing material to the frame so that the tension is maintained as in the related art. And, instead of this, simply the crown member 8
Can be easily displaced upward, so that the roofing material 5 can be easily brought into a completely expanded state when the roof is erected.

In addition, in this embodiment, the top crown member 8 is
Since it is configured to be displaced in accordance with the final displacement of the bundle member 3, the extension of the roofing material 5 and the application of tension to the roofing material 5 can be performed at one time. Therefore, the workability is extremely excellent. For reference, when the roof A is removed, the bolts 6 are completely removed from the nuts 7, that is, the vertical member 1 and the bundle member 3 are completely separated from each other.
It will be folded compactly.
