It only needs to be provided, and it does not particularly hinder the movement of the joist 10 or the floor panel 20 in the other directions. The relationship between the supporting portion and the engaging portion is the same not only for the floor structure according to the invention described in claim 1 above but also for the floor structure according to the inventions according to claims 2 to 6 shown below.

In each of the floor structures shown in FIGS. 2 to 4, the supporting portions 111, 112, 113 are formed so as to project upward, and the engaging portions 211, 212, 213 are formed.
Are fitted from above, so that the floor panel 20 can be easily installed. In the embodiment shown in FIG. 2 or FIG. 3, the two supporting portions 111 and 112 arranged in parallel are supported by one supporting leg 30,
The support leg 30 may be provided corresponding to each of the two support portions 111 and 112. Moreover, FIG.
In the embodiment shown in FIG. 4, the joist 10 is supported by the support legs 30, but the joist 10 is directly installed on the ground floor without the support legs 30. Good.

Next, FIGS. 5 and 6 show an embodiment (fourth embodiment) of the floor structure according to the present invention. This floor structure is composed of an elongated joist 10 supported by support legs 30 and a floor panel 20 installed between the joists 10, and the joist 10 is projected upward in the upper part thereof. The floor panel 20 has a supporting portion 114 formed of a ridge formed continuously in the longitudinal direction, while the floor panel 20 has an engaging portion 214 formed in a concave shape on the lower surface thereof so that the ridge of the supporting portion 114 can be fitted. have. The opening width of the concave engaging portion 214 is larger than the thickness of the protrusion of the supporting portion 114, and a clearance is provided between the supporting portion 114 and the engaging portion 214 so that the supporting portion 1 is formed.
14 and the engaging portion 214 are engaged in a loosely fitted state. Therefore, in this floor structure, as shown in FIG. 5, the floor panel 20 is rotatable about the engaging portion 214 as a fulcrum when the engaging portion 214 is engaged with the supporting portion 114. Has become.

Joist 1 having such a supporting portion 114
0 and the floor panel 20 having the engaging portion 214 maintain the engagement between the supporting portion 114 and the engaging portion 214 even if the base floor surface F is inclined or uneven as shown in FIG. The floor panel 20 is supported by the joist 10 by adjusting the positions of the joist 10 and the floor panel 20 as it is, and the wiring / piping material storage space 40 is formed under the floor.

FIG. 7 shows another embodiment (fifth embodiment) of the floor structure according to the second aspect of the present invention. This floor structure is composed of a ridge formed on the joist 10. Support part 11
5 has a spherical body 115a at its tip, and the floor panel 20 has a concave engaging portion 2 which is in sliding contact with the spherical body 115a.
15 is formed so that the floor panel 20 is tiltably supported by the joist 10.

FIG. 8 shows still another embodiment (sixth embodiment) of the floor structure according to the second aspect of the present invention. In this floor structure, the support portion 116 formed of a protrusion is elastically deformable, and the support portion 116 is engaged with the engaging portion 21.
A floor panel 20 is tiltably supported by the joist 10 in a state in which 6 is engaged. This floor structure can be used in combination with the floor structure shown in FIG. 6 or the floor structure shown in FIG. 7, and in this case, there are the following advantages. That is, when it is necessary to rotate the floor panel 20 more than allowed by the engagement in the loosely fitted state (FIG. 6) or the engagement by the spherical body (FIG. 7), the floor deformation is caused by elastic deformation of the support portion 116. The panel 20 can be rotated to correspond. Further, since the floor panel 20 can be rotated by the elastic deformation of the support portion 116, the space between the adjacent floor panels 20 can be reduced in the floor structure shown in FIG. 6 or 7.

The support portion is, as shown in FIG.
The supporting portion 11 which is elastically deformed by bending itself
6 and the core material 1 as shown in FIG. 9 (seventh embodiment).
Support part 11 in which elastic material 117b such as rubber is fitted to 17a
7, the elastic member 117b may be elastically deformed when the floor panel 20 rotates while the engaging portion 217 is engaged. The joist 10 is not limited to being supported by the support legs 30, but may be directly installed on the ground floor without the support legs 30.

The floor panel 20 has a large number of ribs 201 in the direction orthogonal to the joist 10 on the lower surface thereof.
The joist material 10 has flexibility in the longitudinal direction and rigidity in the direction orthogonal to this. The joist 10 has a supporting portion 118 formed of a ridge formed on the upper portion thereof so as to project upward and continuously in the longitudinal direction.
Has on its lower surface an engaging portion 218 formed in a concave shape that can be fitted to the protrusion of the supporting portion 118.

In this floor structure, the floor panel 20 is supported while the engaging portions 218 are engaged with the supporting portions 118 of the joists 10 arranged at predetermined intervals.
However, due to the flexible construction of the joist 10 in the longitudinal direction, as shown in FIG. 11, the joists 10 arranged at predetermined intervals on the base floor F are inclined differently in the longitudinal direction. Even when the floor panels 20 are arranged in a state, the floor panel 20 spanned between the joists 10 is bent by its flexibility, and the floor surface can be configured with necessary rigidity.

Next, FIG. 12 shows an embodiment (9th embodiment) of the floor structure according to the invention of claim 5. This floor structure includes a long joist 10 supported by support legs 30 and a floor panel 20 installed between the joists 10.
The joist 10 is provided with a supporting portion 119 formed of a ridge formed upward and protruding continuously in the longitudinal direction, while the floor panel 20 has the supporting portion 119 on the lower surface thereof. It has an engaging portion 219 formed in a concave shape that can be fitted to the ridge. And the floor panel 20
Is formed in a substantially triangular shape in plan view, which is continuously supported in the longitudinal direction with respect to one joist 10 and is pole-supported in the longitudinal direction with respect to the other joist 10.

In this floor structure, the floor panel 20 is
The structure in which one joist 10 is supported by a so-called line, and the other joist 10 is supported by a so-called point, provides a degree of freedom capable of supporting the floor panel 20 inclined around the point. Similarly to the floor structure according to the invention described in claim 4, even when the plurality of joists 10 supporting the floor panel 20 are arranged in different inclined states in their longitudinal directions, the joists are also provided. A floor panel 20 can be installed between 10 to form a floor surface.

Next, FIG. 13 shows an embodiment (tenth embodiment) of the floor structure according to the invention of claim 6.
This floor structure has a plurality of support legs 30 having a height adjusting mechanism.
Long joist 10 supported by and the joist 1
The floor joist 10 has a supporting portion 120, and the floor panel 20 has an engaging portion 220 that engages with the supporting portion 120. The floor panel 20 is supported by the joist 10 with the engagement portion 220 engaged with the support portion 120. The support leg 30 includes a bolt 310, a main body 320 that accommodates a nut 321 that is screwed into the bolt 310 and is fixed to the bottom of the joist 10, and a pedestal 330 that supports the bolt 310. The main body 320 has elastic protrusions 322 on both sides thereof, and the elastic protrusions 322 are fitted between the flanges 101 formed on both sides of the bottom of the joist 10.
The locking projection 323 provided at the tip of the is locked to the engaging recess 102 provided inside the flange 101 and fixed in a retaining state. Further, the pedestal 330 has a set screw 331 for fixing the bolt 310 after the position adjustment.
