JPH0996011A - Earthquake-proof pedestal for support - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make a support of a building earthquake-proof, and to make erection of the support easy. SOLUTION: A holding plate 3 is fixed to a concrete pedestal 1 with anchor bolts 2. A free base board 6, provided with a center column 7, is placed at the center of the holding plate 3. Then, a pressing plate 4 is welded to the holding plate 3 so that fitting spaces 5, each in a C-shape section, can be formed thereunder. Clearances allowing the free base board 6 with the center column 7 to float must be provided at the fitting spaces 5. Lateral shaking arising from an earthquake can be absorbed by floating of the free base board 6, and a support 8 can be prevented from breaking. The support 8 can be erected only by fitting onto the center column 7. With beams 9 and floor beams 10 arranged between the supports 8, a framework of a building can be erected. Erection of the supports 8 an construction of the building can be executed simply and efficiently.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic resistant column base.

[0002]

2. Description of the Related Art Conventionally, since the pillars of a building have been erected directly and rigidly on a foundation, they were easily damaged by being directly subjected to the shaking of an earthquake. In addition, when erected, the work efficiency was poor, such as embedding each piece of concrete.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a seismic support column base which is excellent in seismic resistance and which allows the columns to be erected easily.

[0004]

Means for Solving the Problems An object of the present invention to achieve the above object is to provide a concrete base, a concrete stand, a holding plate having a holding plate for forming a fitting gap, and a fitting gap of the holding plate. It is characterized in that it is composed of a free substrate with a pillar that is movably held in the substrate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. In FIGS. 1 and 2, a holding plate 3 is fixed to a concrete stand 1 by anchor bolts 2. The holding plate 3 is provided with a pressing plate 4 that forms a fitting space 5 having a cross section U. In the present invention, the free substrate 6 with the pillar 7 is movably held in the fitting space 5 having a U-shaped cross section so that the shaking caused by an earthquake can be absorbed.

In the production of this earthquake-resistant pillar base,
After the holding plate 3 is fixed to the concrete stand 1 with the anchor bolts 2, the free substrate 6 with the pillar 7 is placed in the center of the holding plate 3. Next, the pressing plate 4 is fitted with a fitting space 5 having a U-shaped cross section.
Weld to make up. In this case, the free substrate 6 with the core 7 is provided with a clearance that allows it to move within the fitting space 5. Therefore, in the present invention, the shaking of the earthquake,
In particular, it can absorb rolling and prevent damage to buildings. In addition, since it can be assembled simply by fitting the pillar 8 to the core pillar 7,
On-site construction is efficient.

FIGS. 3 and 4 show a state in which the support column 8 of the present invention is assembled with the support column 8 fitted therein. In the present invention, the building can be assembled simply by fitting the hollow pillar 8 to the core pillar 7. 9 is a beam and 10 is a floor beam. An example of the structure thus assembled is shown in FIGS. 5 and 6. Hollow columns 8 are fitted into the core columns 7 of the four seismic resistant column bases of the present invention, and beams 9 and floor bars 10 are passed between the columns 8. Reference numeral 11 is a wall, 12 is a window, and 13 is a door.

[0008]

The seismic resistant column base of the present invention has the following advantages and can be widely applied to the construction of simple structures. (B) Since a free board with a pillar is freely attached to the concrete stand, it is possible to effectively absorb the shaking of the earthquake.
Avoid building damage. (B) At the construction site, it is only necessary to fit the hollow pillars to the core pillars of the seismic resistant pillar base, so the assembly work is simple and efficient.
