DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for supporting and fixing a lower end of a support such as a shelf installed on a concrete slab.

[0002]

2. Description of the Related Art Heretofore, as this type of supporting device, there is, for example, one disclosed in Japanese Utility Model Publication No. 54-42498. That is, a plurality of threaded steel materials are juxtaposed in the direction of the wife above the discarded concrete, and these steel materials in the direction of the wife are supported by a plurality of bundles erected on the discarded concrete. And the through steel materials arranged in parallel in the girder direction are attached by welding to the through steel materials in the end direction. Bases are attached by welding to predetermined positions on the upper surface of the through steel material in the direction of each girder, and anchors are detachably attached to these bases. The lower ends of the columns of the building are placed on these bases and connected and fixed by anchors. Also, except for the base, the steel material below the girder direction is buried in the concrete slab.

[0003]

However, in the above-mentioned conventional type, when the supporting device is installed, a plurality of bases and the through-steel material in the girder direction are separately carried into the installation site of the building, and thereafter, Since a plurality of bases were attached to the through steel members in the girder direction by welding at the installation site, it took time to carry these bases and through steel materials into the site and to perform welding work for installation.

An object of the present invention is to solve the above problems and to provide a supporting device for a lower end of a structural support, which can reduce assembling work on site.

[0005]

According to a first aspect of the present invention, there is provided a support device for supporting a lower end of a structural support, comprising: a pair of mounting members disposed in a horizontal direction; Provided with a plurality of unit bodies formed by the formed base plate, provided with support members for supporting these unit bodies at a predetermined level, and attached to the base plate by inserting anchor bolts for connecting and fixing the lower ends of the structural columns. It is.

The supporting device for the lower end of the structural support in the second aspect of the present invention is one in which the mounting member and the base plate are connected by a detachable connecting tool.

[0007]

According to the structure of the first aspect of the present invention, a plurality of unit bodies are previously formed in a manufacturing factory or the like by bridging a base plate between a pair of mounting members. Then, by carrying these unit bodies to the site, the work of assembling the mounting member and the base plate at the site can be omitted, so that the work at the site can be reduced.

According to the configuration of the second aspect, when the unit body is formed by bridging the base plate between the pair of mounting members,
Since the mounting member and the base plate are connected by a detachable connecting tool, welding is not required, and thus the connecting operation is facilitated.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 6, reference numeral 1 denotes a pair of mounting members disposed at a predetermined level above the cast concrete 2. These pair of mounting members 1
Each of them extends in the span direction, and is arranged in plural sets in parallel. Angle materials are used for these mounting members 1.

A gate-shaped base plate 3 is bridged between the pair of mounting members 1 with the open surface facing downward. A plurality of these base plates 3 are provided in the span direction, and bolts and nuts 4 inserted into the lower portions of both side plate portions (an example of a connecting tool)
Are connected to the mounting member 1 respectively. The upper part of the base plate 3 is divided into two parts in the span direction. As shown in FIG. 2, a unit body 5 is formed by the pair of mounting members 1 and the base plate 3.
Is supported at a predetermined level by a support member 6 erected on the waste concrete 2.

That is, each of the mounting members 1 is supported on the discarded concrete 2 by the bundle member 8 via the connecting member 7 extending in the girder direction. Angle materials are used for the connecting members 7 and are arranged side by side at predetermined intervals. The mounting member 1 is placed on a connecting member 7 and connected by bolts and nuts 9.

Each connecting member 7 is connected to the upper end of the bundle 8 by bolts and nuts 10. A channel material is used for these bundles 8, and is arranged opposite to a landing plate 11 that lands on the upper surface of the discarded concrete 2. A level adjusting bolt 12 is provided between the lower end of each bundle 8 and the landing plate 11, so that the level of each bundle 8 can be adjusted. The landing plate 11 is fixed by anchor bolts 13 cast on the discarded concrete 2. The girder direction stick 14 for maintaining the connection strength in the girder direction includes bolts and nuts.
The connection member 15 connects the connecting member 7 and the bundle member 8 to each other. Further, a span direction stick 16 for maintaining the connection strength in the span direction is connected to the mounting member 1 and the bundle member 8 by bolts and nuts 17.

A pair of anchor bolts 19 are inserted through the pair of top plates 18 of each of the base plates 3 in the direction of the girder. These anchor bolts 19 are of a straight type, and a disc portion 19a larger than the bolt diameter is formed at the lower end thereof to improve the pull-out strength. As shown in FIG. 6, the lower part of the upper surface of the base plate 3 is a concrete slab.
20 is buried inside, and the upper surface of the base plate 3 is a concrete slab
It is exposed on the upper surface of 20.

As shown in FIGS. 4 and 5, reference numeral 23 denotes a plurality of shelves installed on the concrete slab 20.
23 has vertical columns 24 provided at predetermined intervals. At the lower ends of the vertical supports 24, a pair of top plate portions 18 of the base plate 3 are provided.
The base plate 25 is mounted on the base plate 3 by the anchor bolt 19 and the fixing nut 26. Note that the pair of top plates 18 of the base plate 3 are formed in a slightly smaller size than the base plate 25.

The operation of the above configuration will be described below.
First, as shown in FIG. 2, a plurality of unit bodies 5 are previously formed in a manufacturing factory or the like by bridging a base plate 3 between a pair of mounting members 1. At this time, since the mounting member 1 and the base plate 3 are connected by the bolts and the nuts 4, welding is not required, and thus the connecting operation is facilitated. After that, these unit bodies 5 are carried into the site, whereby the mounting members 1
The work of assembling the base plate 3 with the base plate 3 can be omitted, so that work on site can be reduced.

Similarly, as shown in FIG. 3, a pair of bundles 8 are erected in advance on a landing plate 11 via a level adjusting bolt 12 at a manufacturing factory or the like to form a unit, thereby enabling a Since the work of assembling the landing plate 11 and the bundle 8 can be omitted, the work on site can be reduced.

After the connecting member 7 is connected to the upper end of the bundle 8 thus installed on the site by bolts and nuts 10, the mounting member 1 carried in the state of the unit body 5 is bolted to the connecting member 7. They are connected by a nut 9. This eliminates the need for welding, which has been conventionally performed, and facilitates installation work.

Thereafter, the anchor bolts 19 are inserted into and attached to the top plate 18 of each base plate 3. At this time, the bundle material 8 is moved up and down by rotating the level adjusting bolt 12,
The base plate 3 can be accurately adjusted to a predetermined level.
Further, a bolt hole (not shown) into which the bolts, nuts 4 and 9 are inserted may be formed in an elongated hole so that the position of the support member 1 can be adjusted by being shifted in the span direction and the girder direction.

When the unit body 5 is formed in advance in a manufacturing factory or the like, the anchor bolt 19 may be attached to the base plate 3. Further, since the lower surface of the base plate 3 is buried in the concrete slab 20 and the upper surface of the base plate 3 is exposed to the upper surface of the concrete slab 20, the possibility that a cavity is formed below the base plate 3 is reduced. Further, since the pair of top plates 18 of the base plate 3 are formed in a slightly smaller size than the base plate 25, the rust prevention treatment on the upper surface of the base plate 3 becomes unnecessary.

In the above embodiment, a shelf is used as an example of a structural support.
Although the 23 vertical columns 24 have been described, this is not limited to the shelf 23 and may be columns such as warehouses and devices.

[0021]

As described above, according to the first aspect of the present invention, a plurality of unit bodies are formed in advance by bridging a base plate between a pair of mounting members in a manufacturing factory or the like, and these unit bodies are carried to the site. By doing so, the on-site assembling work of the mounting member and the base plate can be omitted, so that the on-site operation can be reduced. Therefore, the on-site assembling work can be largely labor-saving, and the construction period can be shortened.

Further, according to the second aspect of the present invention, when the unit body is formed by bridging the base plate between the pair of mounting members, the mounting member and the base plate are connected by the detachable connecting tool. It is no longer necessary, thus facilitating the connection operation.
