BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expansion joint apparatus for covering a strain absorbing gap provided in a building, and more particularly to a display type expansion joint apparatus having a function of transmitting information on the wall surface of the building. It is a thing.

[0002]

2. Description of the Related Art In a large building, a gap structure is constructed as a means for preventing expansion and contraction due to temperature change, unequal settlement, and damage caused by strain due to earthquakes, etc. An expansion joint device having a structure in which a pair of frame bases are fixed to the ends of a building with a gap therebetween and a cover plate is slidably covered and connected between the frame bases is generally used.

[0003]

Most of the conventional expansion joint devices described above are constructed so as to be integrated with a wall surface, and have a structure in which a flat cover plate is arranged in parallel with the wall surface. Since it is a mere strip-shaped structure extending along the surface of the gap structure, a large vertical line formed by the expansion joint device appears on the wall surface of the building, which divides the design of the entire building. However, due to various regulations in the event of a disaster, the old structure is still used as it is, and the actual situation is that improvement has not progressed.

The present invention has been made in view of the above problems, and a display having a novel structure in which the expansion joint device itself has a visual information transmission function and can be expected to have another function in addition to the original function. It is an object of the present invention to provide a mold expansion joint device.

SUMMARY OF THE INVENTION In a display type expansion joint device according to the present invention, a covering member is slidable between base frame members fixed along the edge of a building with a strain absorbing gap therebetween. In an expansion joint device having a structure in which the covering member is hooked and connected to cover the gap, the covering member is slid in the width direction of the strain absorbing gap so that both end edges of the covering member come close to or slide on the surface of the building. The flat display device is fixedly mounted on the entire surface of the covering member or a part of the surface of the covering member, and the flat display device is driven to display various information via a display control drive circuit. That is the summary, and as the flat display device,
It can be implemented by a liquid crystal display or an LED display in which a large number of LEDs are arranged vertically and horizontally.

[0006]

In the display type expansion joint device described above, the covering member is installed between the base frame members fixed to the edges sandwiching the gap of the building in such a manner that the displacement of the strain absorbing gap is not restricted.
Since a flat type display device such as a liquid crystal display or an LED display in which a large number of LEDs are arranged vertically and horizontally is arranged on the surface of the covering member, the expansion joint mechanism of the building is used as an information transmission function section. can do. Of course, the structure portion that constitutes the expansion joint mechanism does not have a structure such as a window, so that it is useful as a large-sized display space, and a pattern or a figure is used as a visual transmission means for the flat display device. Alternatively, the characters can be displayed by being displayed.

Embodiments of a display type expansion joint device according to the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment in which a liquid crystal display device made of a thin metal plate is arranged. Reference numerals 1 and 1 are a pair of base frame members fixed along the edges of the buildings a and a with a gap G therebetween, and the buildings a are attached to the building a by anchor bolts (not shown) or the like. It is fixed on the surface of.

Reference numeral 2 is a display supporting structure in which a frame member 3 constitutes a vertically long frame assembly having a width sufficient to cover the strain absorbing gap G and a back plate 4 for covering the gap is stretched on the back surface. Yes, the display support structure 2
Is formed by laterally fixing a plurality of guide rails 5, 5 ... Having a C-shaped cross section with respect to the backing plate 4 for gap coating, at appropriate intervals in the vertical direction, and projecting onto the base frames 1, 1. The cylindrical locking ends 7, 7 formed at the tips of the supporting projections 6, 6 provided are pivotally attached to the groove of the guide rail 5 so as to be slidable in the longitudinal direction and displaceable in the engaging angle. , A without supporting the expansion and contraction of the strain absorbing gap G and the tilt thereof.
Is supported on the wall surface in front of the gap G.

In the flat inner cavity 8 of the display support structure 2, a large number of liquid crystal display plates 9, 9 ... Spread in the plane direction and divided into appropriate unit areas are continuously arranged vertically and horizontally. , Liquid crystal display controller 1
The liquid crystal display device 11 comprises a flat display unit for displaying a video signal input from a video display circuit (not shown) by 0 as one symbol or video. Further, reference numeral 12 in the drawing is a surface plate made of a transparent material which covers the front surface of the display support structure 2.

Reference numeral 13 is a center positioning mechanism,
One end of a pair of equal-length arms 14 and 15 is rotatably connected via a pin shaft 16 that constitutes a slider 17, and the other ends of both arms 14 and 15 are connected to the base frames 1 and 1. The slider 17 is rotatably pivotally attached to a corresponding position via a pin shaft 18, and is provided on a guide rail 19 having a C-shaped cross section which is configured to extend in the longitudinal direction at the center of the gap covering back plate 4. It becomes the structure which engaged. A plurality of the center positioning mechanisms 13 are arranged at appropriate intervals in the vertical direction of the display support mechanism 2.
It is provided.

In the display type expansion joint device having the above-mentioned structure, the columnar engaging ends 7, 7 of the supporting projections 6, 6 projectingly provided on the two base frame members 1, 1 and the guide rail 5 form a hinge structure and slide. The flat display part of the liquid crystal display device 11 is incorporated because the display support mechanism 2 is always supported in the center of the gap G by the center positioning mechanism 13 while being freely pivoted so that the engaging angle can be displaced. The display support mechanism 2 is positioned so as to always cover the gap G between the buildings a and a.

By displaying a picture, a character, or a moving image on the surface of the liquid crystal display plates 9, 9, ... Of the liquid crystal display device 11, the action as an information transmission medium can be sufficiently exerted.

Next, FIG. 3 shows another embodiment of the present invention in which an LED is used as a flat display device. The display portion of the flat display device is a substrate 2 stretched in a flat inner cavity 8 of a display support structure 2.
A large number of LEDs 2 arranged in a matrix in the vertical and horizontal directions
An LED display 22 in which 1, 21, ...
Is driven by blinking by a video signal input from a video display circuit (not shown) to form a flat display unit for displaying as one symbol or video.

In the present embodiment, as the flat display unit, an LED display using a liquid crystal display plate and a large number of LEDs arranged in a plane have been described, but a large number of neon tubes are arranged in a plane. It is needless to say that the same can be done even if they are arranged.

[0015]

As described above, the display type expansion joint device according to the present invention can display a design, a character or a moving image on the cover structure of the expansion joint configured to cover the gap of the building. Since the flat display device is configured, it has a feature that a function of a new information transmission medium capable of transmitting information by video can be added in addition to the original purpose of covering a gap. The practical effect after implementation is extremely large.
