It is comprised from the guide notch parts 45a and 45a.

  The bundle portion 20 connected to the joist receiving main body 40 is formed based on a C-type steel material having the same width as the joist receiving main body 40. That is, the bundle part 20 is connected to the bottom part 20a, the inner part 20b standing from the inner end of the bottom part 20a, the outer part 20d standing from the outer end of the bottom part 20b, and the upper end of the inner part 20b. An upper surface portion 20c to be provided and an outer portion 20e hanging from the tip of the upper surface portion 20c are provided. A hole 20f into which the bolt 30 is inserted is formed at the center of the upper surface portion 20c, and a fixing nut 33 is fixed by welding below the hole 20f (the back surface of the upper surface portion 20c).

  And the disc part 35 is attached to the volt | bolt 30 inserted by the hole 20f and the fixing nut 33 so that it may be located above the said upper surface part 20c. An elastic member 38 is placed on the upper portion of the disk portion 35. Further, a lock nut 32 having a flange portion 32 a on the lower surface is attached to the upper portion of the bolt 30. Four tongue pieces 35a are provided on the outer periphery of the disk portion 35 at intervals of 90 degrees from the center portion.

Moreover, the elastic material 70 is attached to the back surface of the bottom face part 20a.
The pair of bundle portions 20 and the single joist receiving main body 40 constitute a set of joist receiving portions 43.
In the upper part of the floor panel 80, a floor finishing material 81 having a shape in which the four corners of the rectangular top plate are cut out is provided. The floor panel 80 is placed so as to straddle between adjacent joists 50 and 50, and the entire floor surface is formed by the plurality of floor panels 80 (floor finishing material 81). The floor panel 80 is configured by fixing a lid portion serving as a floor surface material on a core material having a reinforcing portion bent in a concave shape. A gap 55 is formed between the floor panels 80 adjacent in the lateral direction, and the upper opening of the joist main body 53 is located below the gap 55 so that the space above the floor and the inner space of the joist water channel 52 communicate with each other. Will be.

  A rectangular top plate 90 is provided between corners (corners) of the adjacent floor panels 80. Below the rectangular top plate 90, as shown in FIG. 8, a dish portion 92 placed between the corners of the floor panel 80 is provided. The plate portion 92 is fixed in position via an engagement plate 95 fixed to the joist main body 53 by an engagement piece 97 and a bolt 93.

Next, a construction example of the floor structure of this embodiment will be described.
The joist 50, the joist support 43 and the floor panel 80 are each produced at the factory and assembled at the construction site.

  At the construction site, the joist receiving main body 40 is attached to a plurality of places in the longitudinal direction of each joist 50. This attachment is performed by fitting the bent portion 40e of the joist receiving main body 40 and the bent portion 51e of the joist main body 53.

  Next, on the floor slab 100, the plurality of joists 50 to which the joist receiver main body 40 is attached are placed in parallel at a predetermined interval (an interval based on the width of the floor panel 80). At this time, a temporary base such as wood may be placed under the joists 50.

Next, the bundle portion 20 is attached to each joist receiving main body portion 40. The bundle portion 20 is a state in which the bolt 30 is fitted into the hole 20f and the fixing nut 33, and the lock nut 32 is loosely attached to the bolt 30, and the disk portion 35 and the elastic member 38 are the joist receiving main body portion 53. The upper part of the bolt 30 is inserted laterally from the guide notch 45a to the circular notch 45b so as to be positioned on the back side of the upper face 40c. This insertion operation may be performed by horizontally moving the bundle 20 from the side of the joist receiving body 40 (the side of the joist main body 53) while standing vertically.
There is no need to incline 0 or remove the bolt 30 from the bundle 20.

Then, the lock nut 32 is tightened until it comes into contact with the expanded portion 40c. At this time, the flange portion 32a of the lock nut 32 enters the circular cutout portion 45b. The vertical position of the bolt 30 with respect to the fixing bolt 33 is a preset position (0 point position), and the height from the lower end of the bundle portion 20 to the upper end (upper surface portion 51c) of the joist body 53 is constant. It is set to become.
After the attachment of each bundle portion 20 to each joist receiving main body portion 40 is completed, the temporary base is removed from below the joists 50.

  Next, the height adjustment of the joist receiving main body 40 is performed so that each joist 50 is horizontal. That is, the joist support body 40 is moved up and down in order to eliminate height errors caused by steps on the surface of the floor slab 100 and molding errors of members such as the floor panel 80. For this purpose, by rotating the bolt 30, the disk part 35 moves up and down together with the elastic member 38, and the joist support main body part 40 moves up and down in response to the vertical movement of the disk part 35. When the joist support main body 40 is vertically positioned, the tongue piece 35a of the disk portion 35 is bent so as to protrude above the expanded portion 40c from the guide notch 45b, thereby preventing the bolt 30 from rotating. In the bending operation of the tongue piece 35a, the bolt 30 is arranged so that the tongue piece 35a closest to the guide notch 45a is positioned below the guide notch 45a when the joist support body 40 is positioned. It is recommended to fine-tune the rotation.

  In addition, each bundle part 20 can also be adjusted so that the drainage gradient in the longitudinal direction of the joist water channel 52 may be set. Since the drainage gradient may be about 1/100 to 1/200, assuming that the total length of the joist 50 is 10 meters, if one end of the joist main body 53 is lifted 50 millimeters from the other end, it takes 200 minutes. A slope of 1 can be obtained.

  Then, after the positioning work of the joist body 53 is completed, the floor panel 80 is installed between the joists 50. And the rectangular top board 90 is attached to the corner vicinity of each floor panel 80, the whole floor is formed with the floor panel 80 and the rectangular top board 90, and construction is complete | finished.

  Then, when the cleaning water is sprinkled on the floor panel 80, the cleaning water drops from the gap 55 to the joist water channel 52 of the joist 50, flows according to the set gradient, and is drained to the drainage channel communicating with the joist water channel 52.

As described above, according to the floor structure of the present embodiment, the floor construction including the adjustment of the height of the joists can be performed with a simple operation. Therefore, even if there is a level difference in the floor slab at the construction site or a molding error in the floor structure product, the work to install the floor panel horizontally or to install the drainage gradient can be done in a short time with simple work. It can be carried out.
According to the floor structure of the present embodiment, a desired gradient can be easily set in the joist waterway, and high drainage efficiency and simple workability can be realized.
