Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement of a joint cover that covers a joint between two orthogonal wall surfaces, such as between two orthogonal side walls or between an adjacent ceiling surface and a side wall surface.

<Prior art> Some joint covers of this type have a simple structure in which the bases of the cover plates are fixed to two orthogonal wall surfaces, respectively, but with this structure, the two wall surfaces can be moved vertically or vertically due to an earthquake or the like. When the cover plate swings from side to side and back and forth, cracks may occur in the mounting base of the cover plate, and in some cases, the two wall surfaces may be damaged. Further, the wall surfaces of the two wall surfaces may not necessarily be in a uniform orthogonal relationship.

The present invention is capable of absorbing the relative movement of two orthogonal wall surfaces in the left, right, front, back, and up and down directions without causing distortion in the cover plate, and can cover the joint beautifully even if the orthogonal relationship between the two wall surfaces is distorted. The purpose is to provide a joint cover that can

<Means for solving the problem> This device is a joint between two walls that are perpendicular to each other.
Fixing bodies are fixed along the respective joints, and connecting support pieces are provided on both fixing bodies so as to protrude in a direction perpendicular to one wall surface, and one of the connecting support pieces is slidably fitted into a fitting groove provided along the fixing body,
This joint cover is characterized in that a connecting rod is inserted between both connecting support pieces, a spring is attached to the connecting rod to bias one of the connecting support pieces toward the fitting side, and both connecting support pieces are covered with cover plates that cover the joints and the insides of which are fixed to both ends of the connecting rod.

<Operation> The cover plate is fixed to both ends of the connecting rod, and is held by the connecting support piece via the connecting rod. The connecting rod is slidably supported along one wall surface by a connecting support piece.

Therefore, when both wall surfaces W ₁ and W ₂ move relative to each other in the X direction in FIG. 1, the cover plate moves relative to one _{wall surface W 1 in the} This means that it can follow the movement.

Furthermore _, when both wall surfaces W ₁ and W ₂ move relative to each other in the Y direction in FIG.
This makes it possible to follow the relative movement of W ₂ in the Y direction.

Furthermore, when both wall surfaces W ₁ and W ₂ move relative to each other in the _Z direction (direction perpendicular to the plane of the _paper ) in FIG. The attached connecting support piece slides, and the cover plate moves in the Z direction with respect to the fixed body, and the cover plate touches the wall surface.
This makes it possible to follow the relative movement of W ₁ and W ₂ in the Z direction. At this time, the connecting support piece is kept in its fitted state under pressure by the spring attached to the connecting rod, so that it can slide without wobbling.

<Example> Embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 3 show a first embodiment of the present invention, which is applied to wall surfaces W ₁ and W ₂ of architectural structures x and x that are perpendicular to each other.

1a and 1b are long fixed bodies 1a and 1b fixed to the corners of orthogonal wall surfaces _W1 and _W2 , and the fixed body 1a fixed to the wall surface _W1 is fixed to the abutting base 2a.
A long hole 3a is formed in the X direction (see Fig. 4), and a fixing screw 5a is screwed from the long hole 3a into a solidifying plug 4a buried in the wall surface _W1 .
It is fixed along the corner. The fixed body 1b, which is also fixed to the wall surface _W2 , has a long hole 3b long in the Y direction formed in the abutment base 2b, and is connected to the wall surface from the long hole 3b.
Fixing screw 5b to solidified plug 4b buried in W ₂
It is fixed along the corner by screwing together. Further, a T-shaped piece is connected to the base 2a of the fixed body 1a, an H-shaped piece is connected to the base 2b of the fixed body 1b,
Fitting grooves 7a and 7b are formed in correspondence with each other on the inside thereof, and fitting grooves 8a and 8b are formed on the outside thereof.

Serrated surfaces are formed on the upper and lower inner surfaces of the fitting grooves 7a and 7b, so that the fitting pieces 11 formed at both ends of the flexible waterstop plate 10 can be fitted and held.

Furthermore, short connecting support pieces 12a and 12b are fitted into the fitting grooves 8a and 8b, respectively. L-shaped fitting pieces 13a and 13b that fit into the fitting groove 8 are formed at the outer ends of the bases of the connecting support pieces 12a and 12b, respectively, and the L-shaped fitting piece 13a of one of the connecting support pieces 12a has a wedge shape. By driving it into the fitting groove 8a, it is impossible to escape. Further, the other L-shaped fitting piece 13b is slidable within the fitting groove 8b. As a result, when the architectural structures x, x move in the Z direction (perpendicular to the paper surface of FIG. 1) as described later, this L-shaped fitting piece 13b will slide against the fixed body 1b. This makes it possible to follow it.

As shown in FIGS. 1 and 2, the connecting support pieces 12a and 12b protrude in the Y direction, and a through hole 14 is formed at the protruding end. A bush 15 having an arcuate surface is fitted into the through hole 14, and two parallel connecting rods 16, 16 are inserted through the bushes 15 of both connecting support pieces 12a, 12b, and are held in line contact by the arcuate surface. Ru.

The screw heads 17a, 17b provided at both ends of the connecting rods 16, 16 have connecting tongue pieces 1, respectively.
8a and 18b are provided, and further a screw head 17a is provided.
A spring 19 is attached between the connecting support piece 12a and the connecting support piece 12a. By this spring 19, the connecting rod 16 is biased to the left in FIG. Even if the fitting groove 8b and the like are deformed, the L-shaped fitting piece 13b retreats against the biasing force, so that its sliding movement can be ensured.

With this configuration, the connecting support piece 12
a, 12b and the two front and rear connecting rods 16, 16 are integrated and arranged at predetermined intervals on the above-mentioned fixed bodies 1a, 1b.

Reference numeral 20 denotes an elongated cover plate that covers the joint y, and has one end bent inward at right angles to form a side piece 21, and the other end is provided with U-shaped packing holding housings 22a and 22b. is formed, and the rubber seal 23

The rubber gaskets 23a and 23b are brought into contact with the wall surfaces W ₁ and W ₂ of the building structures x and x.

Thus, inside the cover plate 20, the connecting rod 16 inserted through the connecting support pieces 12a and 12b is fixed in a span-like manner.

Note that the cover plate 20 is first fixed by fixing the fixing body 1a,
1b is fixed to the wall surfaces W ₁ and W ₂ , and the connecting support pieces 12 a and 12 b and the connecting rods 16 and 16 are assembled.

If this spring 19 is not provided, the connecting support piece 12
If the wall surface _W1 is inclined, not only will it cause looseness when sliding in the fitting groove 8b,
Since the plurality of connecting rods 16 installed along the fixed bodies 1a and 1b all protrude and move toward the wall surface _W2 , the above-mentioned gap is not formed, which causes the problem of making the installation work extremely troublesome. arise.

In this attached state, if the building structures x, x move relative to each other in the X direction due to an earthquake or a rainstorm, the connecting support piece 1
The spacing between 2a and 12b varies along the connecting rod 16. At this time, a spring 19 is attached to the left end of the connecting rod 16.
Because it is attached, its biasing action prevents rattling.

Also, when moving relatively in the Y direction, the button 15
The connecting rod 16 tilts while being supported in line contact with the inner surface of the building structure, and can follow the movement of the architectural structures x.

Furthermore, even in the case of relative movement in the Z direction, the L-shaped fitting piece 13b remains in the fitting groove 8b of the fixed body 1b.
It follows by sliding inside. At this time, as mentioned above, according to Article 19,
The connecting rod 16 is biased to the left in FIG. 1, and the connecting support piece 12b is biased in the fitting direction. By retracting the piece 13b, its sliding can be done smoothly.

Therefore, in the above configuration, the cover plate 20
follows the movement of the building structure parts x, x in the X, Y, and Z directions.

Then, the L-shaped fitting piece 34b of one connecting support piece 32b is made into a wedge shape and is driven into the fitting groove 38b so that it cannot escape, and the L-shaped fitting piece 34a of the other connecting support piece 32a is inserted into the fitting groove 38a. It is possible to slide.
Further, the spring 39 urges the L-shaped fitting piece 34a to the left side in the figure to ensure its fitted state and to enable smooth sliding in the Z direction with respect to the fitting groove 38a.
