The gantry of the present invention supports the pillar member having the upper end portion and the lower end portion formed in a wedge shape by using the above-mentioned first bracket and second bracket that can be attached to and detached from the pillar. Fastening members such as nails and bolts are not necessary for mounting the bracket, and a tool for fixing the gantry is not necessary, and the gantry can be easily fixed to the support column. Further, in the case of supporting the beam member from below, the supporting member to be supported needs to have a certain thickness, for example, a width similar to that of the beam member or the column member. Therefore, when the gantry is provided in two or more stages, the support material of the gantry located in the upper stage hinders the placement of the load and reduces the area where the load is placed. When the beam member is supported by the suspension structure as in the present invention, the connecting member that supports the beam member can be made thinner than the beam member or the column member. Therefore, it is possible to secure a wider area for arranging the luggage, as compared with the case where the beam member is supported from below. Further, by adopting the hanging structure, it becomes possible to position the connecting member on the outside of the beam or column so that the connecting member does not interfere with the luggage, for example.

A preferred configuration of the gantry will be described.

A pedestal-side support portion that supports and has a first end portion and an abutment portion located at an end portion on the opposite side of the first end portion, and the pedestal-side support portion at a distance larger than the depth length of the column. A column-side support portion having an engagement portion located at an end in the same direction as the first end portion of the gantry-side support portion, and one side portion of the gantry-side support portion. A case where the pedestal is fixed to the support column from a connecting portion that connects the side portion and one side portion of the pillar-side support portion located in the same direction, and the abutting portion of the pedestal-side support portion. And an extension portion formed so as to extend along the support column, and when the mount is fixed to the support column, the contact portion of the mount-side support portion contacts the front surface of the support column, The engaging portion of the side support portion engages with the back surface of the column, and the wedge-shaped end portion of the column member is inserted into the insertion portion formed between the gantry side support portion and the front surface of the column. This is solved by the fact that the pedestal is fixed to the column by being inserted.

With the bracket having the above structure, fastening members such as nails and bolts are not required for attaching the bracket to the column, so that the pedestal can be easily fixed to the column.
Further, if the length of the column-side support portion in the height direction is smaller than the length of the gantry-side support portion in the height direction, even after the bracket is attached to the column, the protrusion of the column to the back side becomes small. .. Therefore, the bracket can be attached to the column even if the gap between the back surface of the column and the wall is small. Further, since the bracket is provided with the extension portion, it is possible to contact the member located at the tip of the extension portion, for example, the foundation or another bracket, and transmit the load of the gantry to the foundation or the other bracket. Further, the height at which the gantry is installed can be set by forming the extension part in a desired length in advance.

Hereinafter, one embodiment of the present invention (hereinafter, this embodiment) will be described with reference to FIGS. 1 to 9. In the following embodiments, the same or similar components are designated by common reference numerals, and the scales of these drawings are appropriately changed to facilitate understanding.

The gantry 2 of the present embodiment is a gantry used as a luggage gantry attached by using the pillar 1. As shown in FIG. 1, a pedestal 2a (second pedestal) is arranged continuously in the vertical direction (upward direction) of the pedestal 2 (first pedestal) attached to one column 1. In the specification of the present application, the side surface of the column 1 to which the gantry 2 is attached is referred to as a front surface 1a, and the opposite side is referred to as a back surface 1b of the column 1. Further, the pedestal 2 and the pedestal 2a arranged on the pedestal 2 have substantially the same structure, and therefore, the pedestal 2 will be mainly described below.
The support 1 to which the gantry 2 is attached is a pillar constituting a building, and the gantry 2 is temporarily installed on the support 1 as a luggage gantry. After the floor and walls are installed, the pedestal 2 is removed from the support 1.

The pedestal 2 is a pillar-shaped column member 3 attached along the column 1, a first bracket 10 detachably attached to the column 1, and supporting a lower end 3a of the column member 3, and a column 1 removable from the column 1. A second bracket 20 that is attached and supports the upper end 3b of the pillar 3. Further, the gantry 2 includes a beam member 4 attached to the pillar member 3 and extending in the horizontal direction, a connecting portion 3c located above the beam member 4 and provided at an end of the pillar member 3, and a connecting portion 4b of the beam member 4. And a connecting member 5 that supports the beam 4 by a hanging structure.

As shown in FIG. 3, the lower end portion 3a of the pillar member 3 is formed in a wedge shape. The lower end portion 3a is inserted into an insertion portion 19 formed by a first bracket 10 described later. As a result, the lower end 3a of the pillar 3 is supported by the first bracket 10. A bolt hole 3d is formed in the lower end 3a formed in a wedge shape. After the lower end portion 3a is inserted into the insertion portion 19, the lower end portion 3a and the first bracket 10 are fastened by the bolt 32 inserted into the through hole 16 of the first bracket 10.

Further, as shown in FIG. 4, the upper end portion 3b of the pillar member 3 is also formed in a wedge shape. The upper end 3b of the pillar 3 is supported by the second bracket 20 by inserting the upper end 3b into the insertion portion 29 formed by the second bracket 20 described later. A bolt hole 3e is also formed in the upper end 3b formed in a wedge shape. After being inserted into the insertion portion 29 at the upper end portion 3b, the upper end portion 3b and the second bracket 20 are fastened by the bolts 32 inserted into the through holes 26 of the second bracket 20.

The beam member 4 is attached to the pillar member 3 so as to extend horizontally from substantially the center of the pillar member 3 as shown in FIG. Further, a stopper 30 formed in a flange shape is provided at the tip of the beam member 4. A connecting member 40 is placed on the beam 4. As shown in FIG. 2, the connecting member 40 is placed so as to extend over the beam member 4 and the beam member 4 of the gantry 2 attached to the adjacent column 101. The presence of the stopper 30 at the tip of the beam member 4 prevents the connecting member 40 from moving and coming off the beam member 4. The beam 4 is bolted to the column 3 and can be assembled at the work site.

The connecting member 5 has a turnbuckle 31. Therefore, the worker can change the length L of the connecting member 5 by rotating the turnbuckle 31 even after attaching the beam 4. By changing the length L of the connecting member 5, the horizontalness of the beam member 4 can be adjusted. By adjusting the horizontal level of the beam member 4, it is possible to place a load in a stable state without tilting the connecting member 40. Further, for example, in the case of a truss structure in which the beam member 4 is lifted from below, the supporting member to be supported is formed to have substantially the same thickness as the column member or the beam member. Since it is supported by the member 5, it can be formed relatively thin. In addition, the connecting member 5 is attached to the outside of the column member 3 and the beam member 4 (on the left side or the right side of the column member 3 and the beam member 4 toward FIG. 2) by adopting a suspension structure as shown in FIG. You can As a result, the connecting member 5 does not interfere with the load placed on the beam 4 and a wider space for placing the load can be secured.

As shown in FIG. 2, the gantry 2 of the present embodiment cooperates with the gantry 2 attached to another adjacent column 101 to place a load. In the present embodiment, three connecting members 40 are laid across the beam 4 of the gantry 2, but three or more connecting members 40 may be installed depending on the load to be placed. Alternatively, a plate-shaped member may be laid across the beam 4.

Further, as shown in FIG. 2, the connection member 5 attached to the column 1 is attached to the column member 3 so as to project to the left side in FIG. 2, whereas the connection member 5 of the gantry 2 attached to the column 101 is attached. The column 5 is attached so as to project from the column member 3 to the right in FIG. In this way, by connecting the connecting members 5 to the pillar members 3 and 3 symmetrically with respect to the central axis between the supporting columns 1 and 101, the connecting members 5 are positioned as far apart as possible and wider. The area is secured.

Next, the configurations of the first bracket 10 and the second bracket 20 will be described with reference to FIGS. 3 to 9. As described above, the first bracket 10 is a member for removably attaching the pillar member 3 to the pillar 1. The first bracket 10 has a gantry-side support portion 11 that directly supports the lower end portion 3 a of the column member 3. In addition, the column-side support portion 12 is provided so as to face the gantry-side support portion 11 at a distance L1 longer than the depth length L0 of the column 1. The gantry-side support portion 11 has a first end portion 11a and an abutting portion 11b that is located at an end portion on the opposite side of the first end portion 11a and that abuts on the column 1 when attached to the column 1.

The column-side support portion 12 has an engagement portion 12a located at an end portion in the same direction as the first end portion 11a of the gantry-side support portion 11, and has a second end portion 12b on the opposite side.
In addition, the first bracket 10 includes one side portion 11c of both side portions of the gantry side support portion 11 and one side portion of the column side support portion 12 located in the same direction as the side portion 11c of the gantry side support portion 11. It has a trapezoidal connecting portion 13 for connecting with 12c.

When the column member 3 of the gantry 2 is fixed to the column 1, the abutting portion 11b of the gantry side supporting portion 11 abuts on the front surface 1a of the column 1, and the engaging portion 12a of the column side supporting portion 12 of the column 1. It engages the back surface 1b. Then, the insertion portion 19 is formed between the gantry-side support portion 11 and the front surface 1a of the pillar 1, and the lower end portion 3a of the column member 3 is inserted. As a result, the pillar material 3 is fixed to the pillar 1. When the first bracket 10 is attached to the column 1, the first bracket 10 is inserted through a gap provided on the opposite side of the connecting portion 13. After the pillar 1 is inserted through the gap, the first bracket 10 is tilted with respect to the pillar 1, as shown in FIG.

In addition, as shown in FIG. 5, the height H2 of the column-side support portion 12 in the height direction is shorter than the length H1 of the gantry-side support portion 11 in the height direction. This is because, for example, when the gantry-side support portion 11 and the column-side support portion 12 are manufactured at the same height, when the first bracket 10 is tilted, the portion protruding to the back side of the column 1 becomes large. By shortening the height H2 of the column-side support portion 12 in the height direction, the portion of the column 1 that projects to the back side is made smaller.

The first bracket 10 is provided with a reinforcing portion 18 across the gantry-side supporting portion 11, the pillar-side supporting portion 12, and the connecting portion 13. Further, below the gantry-side support portion 11, an extension portion 17 formed so as to extend along the stanchion 1 from the contact portion 11b of the gantry-side support portion 11 when attached to the stanchion 1 is provided. .. A convex portion 42 is formed at a position above the foundation 41 near the base of the pillar 1. The position of the first bracket 10 is determined by the extension portion 17 contacting the convex portion 42. Further, the extension portion 17 contacts the convex portion 42, whereby the load of the gantry 2 is received by the extension portion 17 and transmitted to the convex portion 42.

Next, the second bracket 20 will be described. The second bracket 20 is a member in which the upper and lower sides of the first bracket 10 are turned upside down, and the configuration is almost the same, but as shown in FIGS. 6 and 8, the first bracket 10 is provided at the tip of the extension portion 27. It has a fitting portion 25 into which the extension portion 17 is fitted.

As described above, the second bracket 20 is a detachable member for attaching the pillar member 3 to the pillar 1, and has the gantry-side support portion 21 that directly supports the upper end portion 3b of the pillar member 3. Further, it has a column-side support portion 22 that is arranged facing the gantry-side support portion 21 at a distance L1 longer than the depth length L0 of the column 1. The gantry-side support portion 21 has a first end portion 21a and an abutting portion 21b located at an end portion on the opposite side of the first end portion 21a.

The column-side support portion 22 has an engagement portion 22a located at an end portion in the same direction as the first end portion 21a of the gantry-side support portion 21, and has a second end portion 22b on the opposite side.
The second bracket 20 includes one side portion 21c of both side portions of the gantry side support portion 21 and one side portion of the column side support portion 22 located in the same direction as the side portion 21c of the gantry side support portion 21. A trapezoidal connecting portion 23 for connecting with 22c is provided.

When the column member 3 of the pedestal 2 is fixed to the column 1, the abutment portion 21b of the pedestal-side support portion 21 abuts on the front surface 1a of the column 1, and the engaging portion 22a of the column-side support portion 22 makes the rear surface of the column 1. Engage 1b. Then, the insertion portion 29 is formed between the gantry-side support portion 21 and the front surface 1a of the column 1, and the upper end portion 3b of the column member 3 is inserted. As a result, the pillar material 3 is fixed to the pillar 1.
When the second bracket 20 is attached to the column 1, the column 1 is inserted through the gap provided on the opposite side of the connecting portion 23. After inserting the column 1 through the gap, as shown in FIG. 4, the second bracket 20 is tilted with respect to the column 1.

As shown in FIG. 6, similarly to the first bracket 10, the height H2 of the column-side support portion 22 in the height direction is shorter than the length H1 of the mount-side support portion 21 in the height direction. By shortening the height H2 of the pillar-side support portion 22 in the height direction, the portion of the pillar 1 projecting to the back side is made small.

The second bracket 20 is also provided with a reinforcing portion 28 across the gantry-side support portion 21, the pillar-side support portion 22, and the connecting portion 23. Further, above the gantry-side support portion 21, there is provided an extension portion 27 formed so as to extend along the stanchion 1 when attached to the support column 1 from the contact portion 21b of the gantry-side support portion 21. Further, at the tip of the extension portion 27 (upper end of the second bracket 20), a fitting portion 25 into which the extension portion 17 of the first bracket 10 of the pedestal 2a arranged above the support 1 is fitted is provided.
