Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembled structure in which girders supported on the upper side of columns are arranged in parallel at intervals in the width direction and are connected in the longitudinal direction via joints.

[0002]

2. Description of the Related Art Assembled structures installed in aisles,
The girders supported on the upper side of the pillars are connected in parallel at intervals in the width direction and arranged in series in the longitudinal direction, and the ends of the girders adjacent to each other in the longitudinal direction are opposed to each other via a joint. Conventionally, there is one described in Japanese Utility Model Publication No. 7-4625.

In this assembled structure, the beams adjacent to each other in the longitudinal direction are bent into a bent shape corresponding to the inclination angle of the inclined surface via a joint above the boundary between the horizontal plane and the inclined surface (eg, stairs, slope, etc.). Connected to. This joint is provided with a pair of brackets each having a large number of insertion holes formed on the tip side and attached to the ends of the girder members whose base sides are opposed to each other, and a connecting shaft for connecting the brackets. Two connecting shafts are inserted through two sets of insertion holes that match each other in accordance with the connection angle, so that adjacent beam members can be connected at an appropriate angle. Therefore, this assembled structure does not need to prepare separate joints to cope with the change in the connection angle of the adjacent girders, or to process the members for connection in accordance with the connection angle at the time of construction. There is an advantage that can be reduced.

[0004]

However, this joint is
Since the connecting member is configured to be inserted by inserting the two connecting shafts into the insertion hole formed in each bracket for the predetermined connecting angle, the predetermined connecting angle is selected stepwise. However, there is a problem that the connection angle cannot be finely adjusted according to the inclination angle of the inclined surface.

Further, in such an assembled structure, it is common to provide a roof for avoiding rain and sun on the upper side of the girder member, and above the joint part of the girder member, a connecting roof corresponding to the connecting angle. Is provided. However, in the conventional assembly structure, the substantial center when changing the connection angle of the joint is the vertical center, and the change in the distance between the upper ends of the opposite beam members due to the change in the connection angle. Is large,
It is difficult to use the same connection roof for each connection part where the connection angles of the beam members are different. Therefore, the size of each connecting part,
There is a problem that a connecting roof having a different shape is required, the number of parts increases, and the cost increases.

Further, in such an assembled construction,
It is desirable to increase the selectable range of the connection angle of the joint. That is, if a joint having the same structure can handle a small connecting angle to a large connecting angle, it is not necessary to manufacture a plurality of types of joints according to the size of the connecting angle, and the cost can be reduced.

In view of the above-mentioned conventional problems, the present invention allows stepless selection of the connection angle of the joint for connecting the girder members in the longitudinal direction, and the gap between the upper ends of the girder members facing each other according to the change in the connecting angle. (EN) Provided is an assembled structure capable of reducing a change in distance, increasing a selectable range of connection angles, and using the same part for each connection part having different connection angles of girders, thereby reducing the number of parts. With the goal.

It is designed to be discharged to the surface 2 side.

In constructing this assembled structure, first, the girder member 4 is attached to the upper side of the column 3 standing on the horizontal surface 1 and the inclined surface 2. At this time, since the girder material 4 is attached to the support pillar 3 on the inclined surface 2 side via the hinge 9, the angle formed by the support pillar 3 and the girder material 4 is continuously selected according to the inclination angle of the inclined surface 2. be able to. Therefore, even when the inclination angle of the inclined surface 2 (angle formed by the column 3 and the girder 4) is different,
The same hinge 9 can be used and the same structure makes it easy to mount.

Next, the opposite ends of the girder material 4 on the horizontal surface 1 side and the girder material 4 on the inclined surface 2 side are connected via a joint 5 at a connection angle corresponding to the inclination angle of the inclined surface 2. . The holding bracket 23 of the joint 5 is provided on one of the ends of the beam members 4 facing each other.
, The fitting bracket 25 is previously attached to the other,
The connecting shaft 21 may be inserted with the insertion holes 22 and 24 aligned. Moreover, since the width of the fitting space 32 of the holding bracket 23 is slightly larger than the thickness of the fitting piece 41 of the fitting bracket 25, the insertion holes 22 and 24 can be easily aligned with each other.

The joint 5 is inserted through the holding bracket 23 fixed to one of the beam members 4, the fitting bracket 25 fixed to the other beam member 4, and the insertion holes 22 and 24 thereof. Since it is configured with the book connecting shaft 21,
Corresponding to the inclination angle of the inclined surface 2, the connection angle of the beam members 4 adjacent in the longitudinal direction can be continuously selected around the connection shaft 21. Therefore, regardless of the inclination angle of the inclined surface 2 (the connection angle of the adjacent beam members 4), they can be easily connected with the same structure.

11 to 14 show examples of selecting various connection angles of the beam members 4 adjacent to each other in the longitudinal direction. In addition, in FIG. 11, the girder material 4 on one side is provided on one side in an inclined shape of 45 degrees downward, and the girder material 4 on the other side is provided substantially horizontally, respectively.
In FIG. 12, one side of the girder member 4 is inclined downward at 30 degrees, and the other side of the girder member 4 is provided substantially horizontally.
FIG. 13 shows that the girder material 4 on one side is provided substantially horizontally and the girder material 4 on the other side is provided on the other in an inclined shape of 45 degrees upward.
Further, in FIG. 14, both are provided substantially horizontally.

As described above, the same joint 5 can be used in each connecting portion 6 having different connecting angles of the adjacent beam members 4, such as the mountain-shaped inclined shape, the valley-shaped inclined shape, and the parallel shape. Of course, connection angles other than the illustrated ones can be continuously selected. Since each of the brackets 23 and 25 of the joint 5 is formed with the inclined edges 35 and 44 which incline from the upper end of the bracket to the lower end side of the base, the beam member 4 on one side or the other side is directed downward to one or the other. When it is provided in the inclined shape of, or when the one side and the other side girder material 4 is provided in the one side and the downward inclined shape, the inclination angle at which the brackets 23 and 25 interfere can be increased, and the connection angle can be selected. The range can be increased.

By increasing the angle formed between the flange portions 26, 36 of the brackets 23, 25 and the inclined edges 35, 44, it is possible to connect the brackets 23, 25 at a larger inclination angle. That is, in this embodiment, as shown in FIG. 11, when the girder material 4 on one side or the other side is inclined downward to one side or the other side by 45 degrees, each bracket 23, 25
Of the mating brackets 25, 23
, But it is impossible to select a connection angle beyond that. For example, the upper edges 34, 43 of the brackets 23, 25 are lengthened to make the flanges 26, 36 and the inclined edges 35, If the angle formed with 44 is increased, the selectable range of the connection angle can be increased.

Further, as shown in FIG. 14, adjacent beam members 4
It is also possible to connect through the joints 5 when connecting in parallel with each other, but in this case, well-known connecting means such as connection through a flat plate-like connecting member may be used. good.

After connecting the girders 4, the main roof 7 is installed across the girders 4 arranged in parallel. The claw portion 51 is integrally provided on the inner surface of the gutter 49, and the claw portion 51 is configured to lock both edges of the roof plate 47 in the width direction.
As compared with a case where a member for pressing the edge portion of the gutter and the gutter 49 are separately provided and attached, the labor of construction can be saved and the number of parts can be reduced.

Next, the connecting roof 8 is attached across the main roofs 7 on both sides of the connecting portion 6. At this time, FIG. 6 and FIG.
As shown in FIGS. 1 to 14, of the adjacent beam members 4, a receiving plate 53 is provided on the lower side and a hanging plate 54 is provided on the upper side. As a result, rainwater or the like can be smoothly guided from the hanging plate 54 side to the receiving plate 53 side. Also, FIG. 11, FIG. 12 and FIG.
As shown in, even when the beam member 4 on the side where the hanging plate 54 is provided is provided in a substantially horizontal shape, the first member 6 of the hanging plate 54 is
Since the planar portion formed by the fourth member 65 and the second member 65 has an inclined shape that descends toward the receiving plate 53 side, rainwater and the like can be reliably guided to the receiving plate 53 side.

The receiving plate 53 and the hanging plate 54 are separately constructed to form the connecting roof 8, and the receiving plate 5 at the tip end side of the hanging plate 54 is formed.
Since they are arranged so as to overlap with the tip side of 3 with a predetermined gap, the connection angles of adjacent girder members 4 such as a mountain-shaped inclined shape, a valley-shaped inclined shape, and a parallel shape are different from each other. The connecting portion 6 can form the connecting roof 8 with the same member, and can reliably guide the rainwater on the hanging plate 54 side to the receiving plate 53 side.

The connecting shaft 21 of the joint 5 is located on the extension line of the upper end edges of the beam members 4 adjacent to each other in the longitudinal direction (on the intersection of the extension lines of the upper end edges when both are provided in a bent shape). Since the upper part of the joint 5 is used as the rotation center of the angle change, the change in the distance between the upper end corners of the beam members 4 facing each other due to the change in the connection angle can be reduced. Therefore, even when the connecting roof 8 and other members are provided above the connecting portion 6 of the girder member 4, it is easy to use the same member regardless of the connecting angle, and the number of parts can be reduced. The cost can be reduced. When the connecting roof 8 is provided as in the embodiment, the distance between the tip end of the receiving plate 53 and the hanging plate 54, that is, the return portion 63 and the bent portion 72, and the connecting shaft 21 can be reduced, so that the change of the connecting angle is changed. The amount of movement of the tip ends of the receiving plate 53 and the hanging plate 54 is small, and it is possible to configure the connecting roof 8 with the same member for a wide range of connecting angles.

As shown in FIGS. 11 and 12, when the girder member 4 on the side where the receiving plate 53 is provided is provided in a downward inclined shape, it is not the contact fixing portion 62 of the first member 55 of the receiving plate 53. If a drainage hole 73 is formed between the contact fixing portion 62 and the fixing portion 61, rainwater and the like can be reliably discharged.

Further, as shown in FIG. 11, when the girder member 4 on which the receiving plate 53 is provided is inclined downward by 45 degrees, and as shown in FIG. 13, the girder member 4 on which the hanging plate 54 is provided faces upward. In this embodiment, the tip side of the receiving plate 53 of the connecting roof 8 and the hanging plate 54 are substantially in contact with each other when inclined at an angle of 45 degrees, so that a larger connecting angle cannot be selected. It is also possible to select a larger connection angle by changing the shape of the tip end side thereof, changing the gap size between the receiving plate 53 and the hanging plate 54, and the like.

15 and 16 illustrate a second embodiment of the present invention. In this embodiment, a girder member 4 is provided on the side of the girder member 4 provided in a substantially horizontal shape, which is substantially orthogonal to the horizontal girder member 4 and is inclined so that the side opposite to the girder member 4 is downward.

As described above, it is possible to provide the horizontal and inclined girder members 4 in a substantially T shape. The short girder member 74 is fixed to the side part of the horizontal girder member 4 substantially orthogonally to the short girder member 7.
4 and the inclined girder member 4 are connected to each other in the longitudinal direction via the joint 5, it is possible to connect them with substantially the same structure as in the first embodiment. Therefore, even if the connection angle between the short girder member 74 and the inclined girder member 4 is different, the same member such as the joint 5 and the connecting roof 8 can be used. In addition, in this embodiment, when the inclined girder member 4 is provided in an inclined shape such that the side opposite to the horizontal girder member 4 is upward, the receiving of the connecting roof 8 is provided above the short girder member 4.
