Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an expansion joint cover, particularly a gap cover installed from the bottom to the top, such as between ceiling panels.

In buildings, between ceiling panels, between ceiling panels and walls, etc., there is usually a distance of several millimeters to several tens of millimeters to prevent expansion, contraction, deformation, or mechanical fluctuations that occur on one side from affecting the other. A gap is provided. This gap is covered by attaching a cover plate that spans the gap mainly because of the need to improve the appearance. However, the installation must not be fixed as it is necessary to accommodate fluctuations such as expansion and contraction, and it is a difficult task to operate from the bottom upwards. That is, the work involves lifting and supporting a long cover plate corresponding to the gap length by hand, and then screwing both sides of the cover plate to both structures, which is extremely inefficient.

The present invention has been made to improve the above-mentioned problems, and to summarize, there is a gap between a pair of edge members fixed to both structures and a pair of ridges attached to the edge members on both sides of the cover plate. In the expansion joint cover, the back surface of the cover plate is provided with an engaging wall having a size that fits an upright wall provided at the end of the edge material on the gap side from the gap side. When installed, the engaging wall is engaged with and held by the upstanding wall of the edge member fixed to the structure.

This will now be explained with reference to attached FIGS. 1 and 2. In the edge material 10 according to the present invention, an L-shaped upright wall 12 extending at right angles to the inner end of the front side of the base plate 11 extends toward the ridge 20, and a locking wall 13 is formed on the outer side.
However, in the center thereof, a rib attachment portion 14 having a groove into which a fitting wall 24 of the rib is inserted is provided extending toward the rib. This edge material 10 is a long material made of metal extrusion, and in this example, a pair of edge materials 1
0,10' is a symmetrical shape. Note that the term "inside" above refers to the gap side below the installed state for use, and "outside" refers to the opposite side, and the same applies hereinafter.

In the attached state, the rim 20 has a pressing part 22, a leg wall 23, and a fitting part to which the gasket 6 can be attached, respectively, at positions facing the upright wall 12, the locking wall 13, and the rim attachment part 14 of the rim material 10. Insert wall 2
In this example, the pair of ridges 20, 20' have a symmetrical shape. The tip of the above-mentioned upright wall 12, 12' and the pressing part 2 of the ridge 20, 20' opposing thereto
2, 22', more precisely, the pressing parts 22, 2
A gap is provided between the gaskets 6 and 6' attached to 2', and the size of the gap is large enough to hold the cover plate 30 therebetween. In addition, the edge materials 10, 10' and the ribbed edge 20,
20' is attached, a space is formed deep inside the gap, and the left and right ends 32, 33 of the cover plate 30, which will be described later,
However, it is designed so that people can come and go as they please.

The lid plate 30 has the edge material 1 on the back side of its flat plate part.
It is a long member made of an extruded metal material having an engaging wall 34 large enough to fit the standing wall 12' of 0' from the inside to the outside, and preferably has anti-seizure grooves 36 at both ends.
37 are provided. Note that the reference numeral 35 in the figure represents a reinforcing rib, which is provided as necessary.

In order to cover the gap with each of the above-mentioned members, first, as shown in FIG. 1, edge members 10 and 10' are fixed oppositely to both ceiling panels 1a and 1b using screws 4 and 4', respectively. At that time, the substrate portion 11' of the edge material 10'
is fixed in such a manner that it protrudes into the gap at least by an engagement margin S that allows the engagement wall 34 of the cover plate 30 to fit outward later. After that, both ends 32 of the cover plate 30,
33 is brought into contact with the tips of the upstanding walls 12, 12' of both edge members, and the cover plate 30 is slid in the horizontal direction shown by the arrow in FIG. 2. Then, the engagement wall 34 fits over the upright wall 12' of the right edge member 10' from the gap side and stops. Therefore, press the cover plate 30 upward with your left hand, maintain that state, and place the pressing part 2 in advance with your right hand.
Holding the right edge 20' with the gasket 6' attached to the edge 2', lock the leg wall 23' shown in FIG. wall 24'
into the groove of the edge attachment portion 14' of the edge material 10'. As a result, the rim 20' is fitted onto the rim material 10', and the right end of the cover plate 30 is connected to the tip of the upright wall 12' of the rim material 10' and the pressing part packing 6' of the rim material 10'. The cover plate 30 is held between the
is maintained in that state. Therefore, the left edge 2
0 to the left edge material 10 in the same manner as in the case of the right side above, and thereby the left end of the cover plate 30,
It is held between the tip of the upright wall 12 and the gasket 6 of the pressing part 22, so that the lid plate 30 is completely connected to the left and right edge members 10, 10' at both ends 32, 33. It is sandwiched between the ridges 20 and 20'. In this state, the engagement wall 34 and the upright wall 12' are still in the state of externally fitting engagement as shown in FIG. The state shown in the figure should be used.

The case where the gap between the ceiling panels is covered has been described above, but FIG. 3 illustrates the case where one of the structures is a vertical wall 1c. In this case, the base portion 11 of the ridge 20 is bent at right angles from the portion 11a to the portion 11b, as shown in the figure, in accordance with the shape of the mounting portion, and the base portion 11 of the ridge 20 is bent at a right angle from the portion 11a to the portion 11b, as shown in the figure.
1 is also different from the case of FIG. 1 in that the structure is bent at a right angle from 21a to 21b.
In addition, since the cover plate 30 is used by sliding left and right, in the case of FIGS. 1 and 2, the distance l between the engagement wall 34 and the right side end is It must be smaller than the distance between the upright wall 12' and the edge attachment part 14', that is, the depth L of the space formed in the innermost part of the gap, but in the case of FIG. and the bent portion 11b of the substrate 11. Such changes will be easily understood as mere design changes.

Furthermore, the fitting walls 24 of the ridges 20, 20',
24' is the edge attachment part 14, 1 of the edge material 10, 10'.
If a snap-in clip mechanism is used when fitting into the groove of 4', the fitting between the two will be more secure. The snap clasp is shown as 5 in the figure. Reference marks 2 and 2' in the figure are ceiling base materials, and 3 and 3' are ceiling mounting fittings.

Since the present invention is configured as described above, when the structure forming the gap is deformed, expanded or contracted, the cover plate 30 moves in and out at both ends of the structure to cover the gap at all times. Even if such fluctuations are large, there are grooves 36, 3 on both sides to prevent loss.
7, it will not easily fit into the tips of the upright walls 12, 12' and fall off. Of course, by using the cover according to the present invention, the man-hours required to cover the gap can be significantly reduced.
