Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a floor structure, and more particularly,
The present invention relates to a floor structure that can be easily and easily attached between joists and tile panels and between tile panels via a joiner.

[0002]

2. Description of the Related Art Conventionally, the underfloor structure of a building is
A flooring work is widely performed in which a bundle with adjustable height is set up, a Daihiki is installed on the bundle, and joists are arranged orthogonally on the Daiki, and a finishing material such as a floor board is spread on the joists. However, in order to attach the floor finishing material to the joists according to this conventional method, fixing means such as nailing or bolting is usually adopted. However, if the fixing means is time-consuming and increases the construction man-hour, and once the floor finishing material is fixed,
It is not convenient because the floor finishing material cannot be easily removed during repair or replacement, and the head of the fixture is exposed on the surface side of the floor finishing material, which impairs the finished appearance. is there.

DISCLOSURE OF THE INVENTION The present invention is to solve the above-mentioned problems, and the gist thereof is a square flat box shape in which joists supported by a floor support bundle and tiles are attached. The tile panel is composed of a joist that connects the joists to the tile panels and between the tile panels, and the joists are elongated hollow bodies having a substantially convex cross section, and are outwardly directed to both upper outer walls thereof. In the tile panel, guide grooves are formed so as to extend upward from the lower ends of both side walls of the panel at the corners, and the joiner has an upper part on at least one side of its main body. Locking projections are provided on both sides of the joint, and locking feet are projected on at least both sides of the lower part of one side, and the locking feet of the joiner are fitted in the fitting groove of the joist. Joiner and lock arm of the joiner To, are those wherein the induced-engaging the guide groove of the tile panel, also,
The floor structure is characterized in that an adjusting clearance is provided between a groove side wall surface of the joist fitting groove and an end surface of a locking foot portion of a joiner engaged with the fitting groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. FIG. 1 is an exploded perspective view showing joists, joiners and tile panels that constitute the present invention, FIG. 2 is a side view showing a state where tile panels are connected to joists on the joists, and FIG. An adjustment clearance set between the joiner and the joiner in the fitting groove is shown in a side view, and FIG. 4 is a front view of the joiner used for connection at the terminating end of the installation.

As shown in a perspective view in FIG. 1, a joist 1 used in the present invention is a long hollow body having a substantially convex cross section.
Fitting grooves 11 are formed by hanging lips 12, 12 from the top surface to both sides to open outwardly on both outer side walls of the upper part of the hollow body.
Is symmetrically arranged. Further, the tile panel 3 used in the present invention is one in which tiles 32 are attached on a rectangular flat box-shaped panel base 31 surrounded by panel side walls 33, and a panel at a corner portion of the tile panel 31. Incisions are made in the lower ends of both side walls 33, 33, and elastic twin pieces 35, 35 are formed to hang down there to widen the tip on the opening side and guide with a narrowed portion in the middle. A groove 34 is provided.

Further, the joiner 2 for connecting the joist 1 and the tile panel 3 and connecting the tile panels 3 and 3 with each other has a locking arm portion 2 on at least one upper side of the main body 21 on both sides.
2 and 22 are provided in a projecting manner, and locking foot portions 23, 23 are provided in a projecting manner at least on both sides of the lower part of one side. In the joiner 2 shown in the above embodiment, four locking arms 22 are provided on both sides of the upper side of the main body 21, and four locking feet 23 are provided on both sides of the lower side of the body 21. In this connection, four tile panels 3 are connected at the same time, but a perspective view is shown in FIG. 4 for connecting the joist 1 at the laying end and the tile panels 3 and between the tile panels 3 and 3. As shown in, a joiner 2-1 having two locking arm portions 22 only on both sides of the upper side of one side and two locking foot portions 23 only on both sides of the lower side of one side is used.

To assemble the present invention, as shown in the side views of FIGS. 1 and 2, a joist 1 is arranged orthogonally on a jack-up large pull 4, and a fitting groove 11 of the joist 1,
Insert the locking feet 23, 23 of the joiner 2 into 11
Slide it to the specified position and place it. After a while
A guide groove 34 formed by cutting into the lower end portions of the panel side walls 33, 33 at the corners of the tile panel 3 is guided and engaged with the locking arm portions 22, 22 of the joiner 2.
Since the tip end on the opening side is expanded and is formed by the elastic twin pieces 35, 35 having a narrowed portion in the middle, the tile panel 3 can be detachably attached from the joiner 2.

When connecting the joist 1 and the joiner 2 of the present invention, as shown in the side view of FIG.
Adjustment clearances d-1 and d-2 are provided between the surface of the groove side wall 13 of No. 1 and the end surface of the locking foot portion 23 of the joiner 2 engaged with the fitting groove 11, respectively.
By setting -1 and d-2 to 0.5 to 2.0 mm respectively, it is possible to absorb a construction error between adjacent joists 1 installed in parallel at the time of construction, and at the same time, The locking foot portion 23 of the joiner 2 is easily fitted into the fitting groove 11 and is easily slid. If it is larger than the above-mentioned set interval, the joint interval between the tile panels 3 installed on this is not uniform, which is not preferable.

[0009]

Since the present invention has the above-mentioned structure, it has the following effects. That is, according to the present invention, it is convenient because the tile panel at a desired position can be easily removed and attached for replacement of design changes or repair, and at the time of construction,
It is possible to absorb the construction error between adjacent joists that are installed in parallel.
