Abstract

PURPOSE:To perfectly shield the earthquake power without obstructing walking and the traveling of a dolly by erecting a plurality of hard plates and elastic wave-shaped plates at a joint part between an earthquakeproof floor and a fixed floor. CONSTITUTION:A plurality of hard strip-shaped plates 3 are erected, keeping a certain intervals, between an earthquakeproof floor 1 and a common fixed floor 2. Each elastic wave-shaped strip-shaped plate 4 is erected between the hard strip-shaped plates 3, and the hard strip-shaped plates 3 are connected, keeping a certain intervals, by the elastic wave-shaped plates 4. The hard strip- shaped plate 3 can surely support the vertical load such as walking person, dolly, etc., and can be slided freely in the lateral direction. While, the elastic wave-shaped strip-shaped plate 4 can surely support a vertical load as in case of the hard strip-shaped plate 3, and prevents the lateral turning-down of the hard strip shaped plates 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a floor structure at a joint portion between a seismic isolation floor and a fixed floor or wall.

[Conventional technology and problems to be solved] In modern buildings, the floors on which precision equipment such as measuring instruments are placed are often made of seismic isolation floors to avoid even the slightest shaking and enable precise measurements. .

In order to prevent the vibration of the building itself from being transmitted to the seismic isolation floor, and to prevent the seismic isolation floor from resisting during an earthquake, it is necessary to use an expansion joint structure at the joint with the normal fixed floor or wall in such a floor. be.

Furthermore, the seismic isolation floor in contact with the fixed floor needs to be at the same level as a normal floor so as not to impede walking or the movement of a trolley, and it must also have a structure that can withstand walking and trolley movement. Furthermore, it is desirable to have a structure that does not resist the vibration of the building during an earthquake.

This invention was developed in view of these circumstances.
A joint between a seismic isolation floor and a fixed floor or wall that does not pose any hindrance to walking or running a trolley, can sufficiently withstand these loads and vibrations, and can almost completely avoid seismic forces. The purpose is to provide a partial floor structure.

[Means for solving problems]

This invention relates to a floor structure at a joint between a seismic isolation floor and a fixed floor or a fixed wall, in which a plurality of rigid strip plates can be slid laterally freely between the seismic isolation floor and the fixed floor or fixed wall. Alternatively, a plurality of corrugated rigid strip plates can be installed horizontally between the seismic isolation floor and a fixed floor or fixed wall. Either the rigid strip plates are connected to each other by multiple strings, or a movable panel can be slid laterally between the seismic isolation floor and a fixed floor or fixed wall. The above purpose is achieved by having a built-in structure.

〔Example] The present invention will be explained below with reference to an illustrated embodiment.

A plurality of rigid strip-shaped plates 1. ... are erected at regular intervals, and the rigid strip plate 1. ... Elastic corrugated strip plate 3 between
．． ... are respectively erected, and the elastic corrugated strip plate 3. Rigid strip plate 1. ...
They are connected at regular intervals (see Figure 1)
.

Rigid strip plate 1. . . . can reliably support vertical loads such as pedestrians and trolleys, and can also slide freely laterally. On the other hand, the elastic corrugated strip plate 3. . . . can reliably support vertical loads in the same way as the hard belt-like plates 1°, and also have the role of preventing the hard belt-like plates 1° from falling laterally.

Also, an elastic corrugated strip plate 3. ... has a spring action, so that the rigid strip plate 1. ...Since the entire structure can be shrunk laterally or restored to its original state and its position can be freely changed, all seismic force is absorbed by this joint part and is not transmitted to the seismic isolation floor 1. do not have.

In addition, hard strip plate 1. A wave-shaped plate is used as..., and the wave-shaped plates 1°... are tied together with multiple strings 4. They may be connected by ... (see Figure 2).

Rigid strip plate 1. ...and elastic corrugated strip plate 3. . . , other shapes such as those shown in FIGS. 3 and 4 can also be used.

Furthermore, by installing a movable floor panel 5 as shown in FIG. 5 between the seismic isolation floor 1 and the fixed floor or wall 2 so as to be able to slide freely in the horizontal direction, the seismic isolation floor 1 can be prevented from absorbing horizontal forces.
transmission can be avoided.

The movable floor panel 5 can support a vertical load, but when it receives a lateral force such as an earthquake force, it slides in the direction of the lateral force, and when one end lifts up, the other end comes off. , the lateral movement of the seismic isolation floor 1 is not blocked by the movable panel 5.

Furthermore, as shown in FIG. 6 or FIG. 7, one end of the movable floor panel 5 is connected to the edge of the seismic isolation floor 1 or the fixed floor 2 so as to be rotatable in the vertical direction, and the other end is connected to the edge of the seismic isolation floor 1 or the fixed floor 2. Transmission of horizontal force to the seismic isolation floor 1 can also be avoided by using a structure in which it is placed so that it can slide freely.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following effects.

It does not pose any hindrance to walking or running a trolley, can sufficiently withstand these loads, vibrations, etc., and can almost completely avoid seismic force.

Furthermore, since all horizontal forces such as seismic forces are absorbed at the 4° joint between the seismic isolation floor and the fixed floor or wall, the shaking of the building itself will not be transmitted to the seismic isolation floor.

Moreover, since the structure is extremely simple, construction and repair are easy.
