Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a large gap expansion joint device for covering gaps in a building frame appearing on the wall surface of a building.

[Prior Art] Buildings are subject to distortion due to constant expansion and contraction due to temperature changes, uneven settlement, earthquakes, etc., so a gap structure is constructed as a means to prevent buildings from being destroyed due to such distortion. Since this gap also appears on the wall surface, an expansion joint is used to cover this gap in a manner that allows it to be expanded and absorb level differences.

As shown in Fig. 4, conventional expansion joints of this type have a frame base 50.
At the same time, the covering plate 51 suspended from the frame base 50.50 is fixed so as to be slidable in the width direction via a hanging member 52 which is extendably installed between the frame bases 50.50. structures have been commonly used.

[Problems to be Solved by the Invention] However, as buildings have become larger in recent years, this strain-absorbing gap has become larger, and in the conventional configuration described above, when one gap structure becomes larger, the width needs to be approximately twice as large. This is because the covering plate 51 is provided on the wall surface.

The front structure of the expansion joint has an undesirable problem in terms of architectural design, in that it disrupts the design of the building.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide an expansion joint device, particularly for large gaps, with a new configuration in which the front structure does not become wider than the gap width.

[Means for Solving the Problems] The expansion joint device for large gaps of the present invention is provided in an expansion joint installed in a strain absorbing gap appearing in a wall of a building, in which the outer walls of both frames are opposed to each other with one gap in between. A pair of frame bases each having a plurality of ribs arranged on the opposing surfaces and having outer edges fixed to both of the frame bases, each having a gap of about a quarter width. a pair of cover plates protruding in a direction that covers G and facing each other, and a sliding cover plate located on the back side of both cover plates and suspended via a hanging means configured between the ribs of both frame bases. Its gist is that it has been constructed from the following points.

Further, the above-mentioned sliding cover plate can be implemented with a laminated structure composed of a plurality of materials including a center plate and side plates that are slidable in the width direction.

Furthermore, the above-mentioned hanging means is composed of a plurality of connecting rods, and both ends of each connecting rod are rotatably pivoted between adjacent members consisting of the frame base, the center plate of the sliding cover plate, and the center plate and side plates. It can be implemented by

[Operation] According to the above configuration, the sliding covering plate located on the back surface of both cover plates is suspended so that the width of the sliding covering plate can be expanded or contracted via the hanging means constituted by the connecting rod. By appropriately selecting the width variation and the sliding range of the cover plate and the sliding cover plate, the gap can be covered by the cover plate and the sliding cover plate.

[Embodiment] An embodiment of the expansion joint device for large gaps according to the present invention will be described below with reference to FIGS. a.

It is a hinge receiving base made of aluminum laminated material fixed to the facing surface of the outer wall edge of a, and each has an L-shaped hinge port 3 rising from the base plate part 2 in the longitudinal direction, and is embedded in the frame a. It is fixed to the opposing surface by an anchor bolt 4. A cylindrical hinge protrusion 6 provided on the outer edge of a frame base 5, 5 made of an aluminum profile is rotatably fitted into the hinge port 3 of the hinge receiving bases 1, 1, respectively. It has a degree of freedom for tilting in the direction of the arrow. The two frame bases 5 have three ribs 7 located on the inner edges.
．． 8.9 and has a substantially E-shaped cross section, and a cover plate fixing rib 10 is integrally formed on the front edge and is installed in the direction in which the one gap structure extends. This is a water stop plate mounting rib formed on the edge. Both frame bases 5 above
, 5, cover plates 12 and 12 made of aluminum profiles are attached to the outer edges of the cover plate fixing ribs 10 with screws 13.
are fixedly installed through the slanted edge 14 side thereof to protrude in a direction covering the gap G by approximately a quarter width, and the two covers have one plate 12,
The sliding cover plate 15 is placed on the back side of the frame base 5.
, 5 are suspended via a hanging means 20 constructed between the ribs 8, 9. The sliding cover plate 15 has a side plate 19 consisting of a front plate 17 and a rear plate 18 on both edges of a center plate 16, and the center plate 16 slides in the width direction shown by arrow B with respect to the side plate 19. It can be freely clamped and integrated. The above-mentioned hanging means 20 is a lip 8
．． 8, one end of which is pivotally connected to the center plate 16 via a bolt 21, and the other ends of the center plate suspension rods 22, 22 are connected to the center plate 16 by screws 23.
One side is attached to the rib 18 via a bolt 24, and the other side is attached to the center plate 16 with a screw 23.
Both side plate suspension rods 25, each having one end pivotally connected via the
25 and the approximate center of the rear plate 18 of the side plate 19 with the screw 26.
It has a structure in which it is pivoted through 1. The center plate suspension rod 22 and the side plate suspension rods 25 are provided obliquely to the direction in which the gap G extends, and are arranged at appropriate intervals.

In addition, in the figure, the surface material is adhered to the surface of the frame a, and the gap between the surface material and the cover plate 12 is filled with a caulking material C made of soft resin to prevent displacement in the direction of the arrow A. It becomes a configuration that does not interfere. Also, reference numeral 27 indicates the mounting ribs 11 and 1 for both water plates.
This is a water stop plate fixed between 1 and 1.

According to the above configuration, the sliding cover plate 15 located on the back surface of both cover plates 12 and 12 is moved to Since it is suspended so that it can expand and contract, the width variation of the sliding covering plate 15 itself due to the center plate 16 and side plates 19 and 19 and the sliding range of the covering plates 12, 12 and the sliding covering plate 15 can be adjusted appropriately. By choosing this, the gap G can be covered by the cover plate 12, 12 and the sliding cover plate 15 by the width of the gap.

[Effects of the Invention] As described above, the expansion joint device for large gaps according to the present invention is constituted by a plurality of plate members laminated with sliding cover plates adjusted on the back side of the cover plate so as to be slidable in the width direction. By suspending the building so that it can expand and contract through a hanging means, an expansion joint can be installed inside the gap, and the facade structure will not be wider than the gap width, thus making it easier to design the building. This invention has the characteristic of being able to reduce the undesirable influence of expansion joints on the air conditioner, and the practical effects after implementation of the present invention are extremely large.
