Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention covers joints generated between adjacent floors and can follow relative displacement between floors in the left-right direction, front-back direction, and up-down direction. The present invention relates to a floor joint cover device.

[Prior Art] As a conventional floor joint cover device, in order to absorb relative movement between adjacent floors, one cover plate is fixed to the floor on one side only, and the other end is attached to the floor on the other side. There is a structure to pass. By the way, in such a structure, since the edge of the cover plate is connected and fixed to one of the floors, the relative movement of the floor in the up-and-down direction causes the cover plate to bend or form a gap, resulting in poor tracking performance.

In addition, this structure requires a sufficient overlapping width between the edge of the joint cover plate and the floor surface in order to maintain a predetermined function,
There is a drawback in that it is necessary to make the entire width wider than the space between joints.

As a modification of this structure, which has vertical followability and a small cover width, as shown in FIG. 5, the support casings a and a are arranged on the left and right floors f and f adjacent to each other through the joint s. Then, the joint cover plate d is passed over by inserting an end edge into the support casing a, and supporting it between the support edges b and c, and the joint cover plate d covers the joint s. It had been. In such a configuration, when the adjacent floors f, f move in the left-right and front-rear directions, the joint cover plate d slides in the support casings a, a to absorb the relative movement and to move vertically When moved, the joint cover plate d is tilted to absorb the relative movement.

[Problems to be Solved by the Invention] In the above-described conventional configuration, the joint cover plate d has the support edges b and c.
Thus, the upper and lower surfaces are supported in line contact with each other and can be tilted with relative movement in the vertical direction. By the way, when the joint cover plate d is inclined, the sandwiching thickness between the support edges b and c is changed. Therefore, if the joint cover plate is thick, the amount of change is also large. Is pushed upward to deform the support casing. Therefore, in such a configuration in which both ends of the joint cover plate d are slidably supported by the support casings a and a, the applicable thickness of the joint cover plate d is limited.

When the joint cover plate d is attached to the support casings a and a, the fixed bodies e and e forming a part of the support casings a and a are fixed to the floors f and f, and then the joint cover plate d is mounted. It is necessary to mount and fix the adherend g constituting the other part of the support casing a and a,
It is necessary to disassemble the support casings a and a when replacing the joint cover plate d when the joint cover plate d is damaged and the replacement is difficult.
There were some drawbacks such as troublesome maintenance.

An object of the present invention is to eliminate the above-mentioned drawbacks in a floor joint cover device in which both ends of a joint cover plate are slidably supported by support casings.

[Means for Solving the Problem] The present invention includes a fixed frame fixed on the left and right floors adjacent to each other through joints, and a side cover on the upper part, and an outer end of the fixed frame and a rotating mechanism. And a movable frame that is in an open position in which the side cover is retracted from the fixed frame by the upward rotation and is connected to the movable frame via the upper frame. A support casing, and a joint cover plate supported by the fixed frame, having side covers mounted on both end edges, and locating the both end edges so as to be slidable left and right in the working space to cover the joint. It is characterized by consisting of.

In this configuration, the joint cover plate may be formed by filling the interior of the lid-shaped main body frame with a floor finish material.

[Operation] The movable frame can be opened and closed with respect to the fixed frame by a rotating mechanism. Therefore, when installing the joint cover plate, rotate the movable frame upward to the open position, remove the side covers from the fixed frame, and then place the joint cover plates on the left and right fixed frames. Then, after that, the movable frame is pivoted inward, and the side covers are attached to the upper edges of both ends of the joint cover plate.

When the left and right floor surfaces relatively move forward, backward, leftward and rightward in such an attached state, the joint cover plate slides on the fixed frame and absorbs the relative movement. Further, when the floors are moved up and down, the edge portion of the joint cover plate is tiltably supported on the receiving frame, and therefore tilts in accordance with the difference in relative movement between the left and right sides. At this time, the sandwiching thickness between the supporting edge and the side cover fluctuates, but since the movable frame is rotatable, this movement absorbs the change in thickness without causing any trouble.

[Embodiment] An embodiment of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, floors f and f are adjacent to each other through a joint s. The joint s for the floor according to the present invention is attached to the joint s to block the joint s. The joint cover device 1 will be described in detail.

The support casings 2, 2 are fixed on the bases at the ends of the floors f, f, respectively.
The support casing 2 includes a fixed frame 3 having a substantially L-shaped cross section, and the fixed frame 3
And a substantially L-shaped movable frame 4 in which a substantially circular convex portion 5a is fitted and connected to a substantially circular concave portion 3a formed at the upper end of the rising portion connected to the outer end of the The working space v in which the inflow of the mortar m is blocked is created inside. The movable frame 4 is composed of a connecting piece 5 having a substantially circular convex portion 5a at its lower end, and an L-shaped metal side cover 6 fixed to the rising portion thereof. A projecting edge 6a is formed continuously on the inner end of the. It is also possible to integrally form the connecting piece 5 and the side cover 6 into a single structure.

In the support casings 2 and 2 having the above-described configuration, a substantially circular convex portion 5a formed at the lower end of the movable frame 4 and a substantially circular concave portion 3a formed at the upper end of the rising portion of the L-shaped fixed frame 3 are rotated. A dynamic connection mechanism is formed, and the side cover 6 can be opened and closed. The joint cover plate 10 to be described later is in the upper rotation position (open position).
Can be installed.

As another example of the rotating mechanism, in addition to a normal hinge structure, a connecting mechanism using an L-shaped connecting piece disclosed in Japanese Utility Model Laid-Open No. 60-141307, Japanese Utility Model Laid-Open No. 62-126403 is disclosed. Various connecting mechanisms such as a connecting mechanism using a C-shaped piece can be applied.

Inside the fixed frame 3, a support projecting edge 3b that rises slightly upward is formed.

A bite part 3c is provided on the outside of the fixed frame 3, and both ends of the water blocking plate 7 made of a flexible rubber plate are sandwiched by the lower surface of the fixed frame 3 and the edges thereof are used as the bite part 3c. It is fitted and fixed to the floors f and f, and the joint s is blocked by the water stop plate 7.

Furthermore, a ridge 8 is tacked on the rising portion of the fixed frame 3 to support the ridge 8 inward.

Reference numeral 10 denotes a joint cover plate, which is formed by filling a floor finish material 12 inside a main body frame 11 having a shallow bottom cover shape.

In this structure, the mounting and fixing will be described.

First, as shown in FIG. 4 (a), both ends of the water blocking plate 7 are clamped by the lower surface of the fixed frame 3, and then the screws 15 are screwed into the fisher plugs embedded in the upper surfaces of the floors f, f to fix the fixed frame. The support housings 2, 2 are installed by fixing 3 together. Thereafter, as shown in FIG. 4B, the movable frame 4 is rotated outward by the cooperation of the substantially circular concave portion 3a and the substantially circular convex portion 5a, so that the movable frame 4 is supported on the supporting projecting edge 3b of the fixed frame 3. Then, the side cover 6 is removed, the joint cover plate 10 is mounted on the supporting projection 3b, and both side surfaces of the joint cover plate 10 are elastically contacted with the ribs 8 and 8 provided in the middle of the rising portion of the fixed frame 3 to attach the joint cover plate 10. It is positioned at the center of the joint s due to the balance of power (see FIG. 1). Then, the movable frame 4 is returned inward, the projecting edge 6a of the side cover 6 is placed on the upper surface of the end edge portion of the joint cover plate 10, and the end edge portion is covered with the side cover 6. The main body frame 11 of the joint cover plate 10 is previously filled with the same floor finishing material 12 as the floor finishing material n attached to the periphery. Thus, both edge portions of the joint cover plate 10 are supported by the support projecting edges 3b and are located in the working space v of the support casing 2.

Then, after this, as shown in FIG. 1, the floor finish material n is arranged while driving the mortar m onto the upper surfaces of the floors f and f so as to be flush with the upper surface of the joint cover plate 10 and adjusting the level. To do.

When the movable frame 4 is tilted largely outward in this construction state, the corner end on the substantially circular convex portion 5a comes into contact with the floor finish material n on the side, and its upward rotation is prevented. Limited. That is, only an opening angle to the extent that the joint cover plate 10 described later can be rotated due to tilting. Thus, after the construction, the joint frame cover plate 10 is not removed by opening the movable frame 4 by mischief or the like. still,
Depending on the mounting location, the movable frame 4 can be constructed so that the movable frame 4 can always be opened. For this purpose, it suffices to install the adjacent floor finishing material apart from the movable frame 4.

The space between the floor finishing material n and the movable frame is filled with the elastic packing 16.

Next, the joint cover device 1 when relative displacement occurs on the floors f and f
The operation of will be described.

When the floors f, f relatively move in the left-right direction, the joint cover plate 1 is moved by the working space v in the support casings 2, 2 as shown in FIG.
0 is slidable with respect to each of the support casings 2,2, so that the relative movement is absorbed by the relative lateral movement of the joint cover plate 10 and the support casings 2,2. At this time, the position of the joint cover plate 10 is held at the center position of the support casings 2, 2 by the balance of the urging force of the spring 8.

Further, when the floors f, f relatively move in the vertical direction as shown in FIG. 3, the joint cover plate 10 inclines in accordance with the vertical position difference between the support casings 2, 2. At this time, since the movable frame 4 is rotatable, the movable frame 4 tilts upward in response to a change in the sandwiching thickness of the joint cover plate 10 between the support projecting edge 3b and the side cover 6,
It can follow each member without deformation. Further, when the sandwiching thickness between the support projecting edge 3b and the side cover 6 is reduced due to the tilting of the joint cover plate 10, only a small gap is generated between the upper surface of the joint cover plate 10 and the side cover 6. There is no hindrance. If the movable frame 4 can also be slightly rotated inward, this gap can be eliminated. In this way the movable frame 4
The rotation angle can be set almost arbitrarily by merely designing.

Thus, the joint cover plate 10 can follow the relative movements of the floors f and f in various directions and can cover the joint s without any trouble.

Although the joint cover plate 10 has the center position maintained by the ribs 8 and 8 in the above-mentioned configuration, even if the ribs 8 and 8 are abolished, for example, the protrusions formed on both lower edges of the main body frame 11 Edge 13
By engaging with the support protruding edge 3b, it is possible to prevent the end edge of the joint cover plate 10 from coming off the support protruding edge 3b. As described above, it is possible to prevent the joint cover plate 10 from being separated from the support projecting edge 3b by various mechanical engagement means.

In the above structure, since the movable frame 4 is rotated so that the joint cover plate 10 can be attached and detached, the joint cover plate 10
Is easy to maintain. That is, when replacing the joint cover plate 10, the floor finishing material in the vicinity is removed (it is not necessary depending on the construction mode), and then the movable frame 4 is rotated upward to replace the joint cover plate 10. do it. Alternatively, even if the joint cover device 1 is damaged due to an earthquake or the like, the screw 15 for fixing the support casings 2 and 2 appears when the movable frame 4 is opened, and therefore the screw 15 may be removed with a tool. For this reason, it is not necessary to disassemble the support casings 2, 2 and maintenance is facilitated.

[Advantageous effects of the invention] The joint cover device 1 of the present invention has the working space v of the support casings 2,2.
The joint cover plate 10 is slidably held by arranging both end edges inside thereof, and the support casings 2, 2 are composed of a fixed frame 3 and a movable frame 4, and the movable frame 4 is rotated. In order to be movable, the edge of the joint cover plate 10 is covered with the side cover 6 of the movable frame 4, which has the following effect.

B) Since the joint cover plate 10 can be easily mounted by rotating the movable frame 4 upward, the joint cover plate 10 is easy to mount, and it is necessary to disassemble the support casings 2 and 2 when replacing the joint cover plate 10. Maintenance is easy.

B) When the floors f, f move up and down relative to each other, even if the joint cover plate 10 tilts and the sandwiching thickness thereof fluctuates, this can be absorbed by the tilting of the movable frame 4, so that the support casings 2, 2 Therefore, the follow-up performance is improved and
There is no limitation on the thickness of the joint cover plate 10, and the joint cover plate 10 of various configurations can be applied.

C) Since there is no problem even if the joint cover plate 10 is thick, the joint cover plate 10 is placed in the main body frame 11 as a floor finishing material.
A structure that can be filled with 12 can also be adopted, in this case floor finishing material
Selecting 12 makes it possible to be in harmony with the surrounding environment.
