Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a floor joint material between units, and particularly when a plurality of units manufactured in a factory are combined on site to form a building, the units are arranged between adjacent units. Structure for fixing a floor joint material to a beam.

[0002]

2. Description of the Related Art In a unit house, a floor joint material is arranged between units located adjacent to each other and placed on a flange surface of a beam to fix the floor joint material (Japanese Patent Laid-Open No. 3-96564). Although the floor splicing material is adhered in the one described in the above publication, generally, a screw penetrating the floor splicing material is fastened and fixed to the beam flange.

[0003]

When fixing a floor joint material by tightening with a screw, a hole penetrating the floor joint material and the flange must be drilled, and then a tapping screw must be screwed in and tightened. The sex is bad.

An object of the present invention is to provide a fixing structure for a floor joint material between units which can improve workability in fixing the floor joint material.

[0005]

According to the present invention, a building unit has a groove-shaped steel beam having a pair of flanges and a web and an opening on one side, and the units are located adjacent to each other. A structure for fixing a floor joint material arranged between units attached with the beams so that the openings of the beams are opposed to each other in a lateral direction, and a width narrower than a space between the upper flanges opposed to each other, A fixing hardware having a length longer than a distance between the webs facing each other is provided, and a screw penetrating the floor joint is screwed into the fixing hardware.

[0006]

[Operation and effect] A screw is penetrated into the floor joint and screwed into the fixed fixture so that there is a gap larger than the thickness of the flange between the lower surface of the floor joint and the upper surface of the fixed fixture. It is guided below the flange through the space between the opposing flanges. After that, when the screw is tightened, the fixing metal member is rotated together with the screw until both ends of the fixing metal member come into contact with the opposing webs. When the screw is further tightened, the fixed hardware moves toward the flange, and holds the flange between the floor member and the fixed hardware. This completes the fixing of the floor joint material.

[0007] It is not necessary to make holes in the floor joint material and the fixed hardware at the site and to connect them with screws, and both can be preliminarily jointed with screws in advance. According to the present invention, since only one screw needs to be provided in the center of the fixed metal object, the workability in fixing the floor joint material can be improved.

EXAMPLE A floor joint fixing structure 10 between units is shown in FIG.
As shown in FIG. 2, the floor joint material 16 disposed between the units 12 and 14 located adjacent to each other is fixed to the beam 18, and the fixing hardware 20 is provided.

Each of the units 12 and 14 has a grooved steel beam 18 having a pair of flanges 22 and 23 and a web 24 and having an opening on one side. The beam 18 is attached to each unit so that the openings of the beams 18 of the units 12 and 14 located next to each other face each other in the lateral direction. In the illustrated embodiment, the floor material 26 and the partition 28 are attached to one unit 12, and the floor material 26 is attached to the other unit 14, but the partition 2
8 may not be provided. A wooden floor joint material 16 is arranged in a gap between the floor materials 26 facing each other.

In the illustrated embodiment, the fixed metal piece 20 is made of grooved steel, but in addition, chevron steel, flat steel or the like can be used. The fixed hardware 20 has a width W2 narrower than the distance W1 between the upper flanges 22 facing each other and a length L2 longer than the distance L1 between the webs 24 facing each other. On the other hand, the width W of the floor joint material 16 arranged on the flange 22 of the beam
Is less than the spacing L1 between the webs and the spacing W1 between the flanges.
Greater than

One fixed metal piece 20 is provided with one screw 30 which penetrates the floor joint material 16 from the upper side to the lower side and is screwed into the fixed metal piece 20. The screw 30 is arranged substantially in the center of the floor joint 16.

The screw 30 is penetrated through the floor joint material 16 and screwed into the fixed metal fitting 20 so that the gap G between the floor joint material 16 and the fixed metal fitting 20 is larger than the thickness of the upper flange 22 as shown in FIG. The fixed hardware 20 is held so that At this time, as shown in FIG. 2, the fixed hardware 20 is oriented so as to be located between the opposed flanges 22. In this state, when the floor joint material 16 is guided to a predetermined position between the adjacent floor materials 26, the fixed hardware 20 is below the upper flange 22. After that, when the screw 30 is turned, the fixed hardware 20 is rotated, and both ends 21 of the fixed hardware 20 abut the facing web 24. Further, when the screw 30 is turned, the fixed hardware 20 moves upward and contacts the lower side surface of the flange 22. The flange 22 is held by the floor joint material 16 and the fixed metal fitting 20, and the fixing of the floor joint material 16 is completed.

When one of the units 12 has a partition 28, a hole is made in the floor joint portion and flange in the vicinity of the partition 28, and the screw is screwed in to fix the floor joint member. However, according to the present invention, even when the partition 28 is provided, such a complicated work is unnecessary.

As shown in FIGS. 3 and 4, a floor joint material 40 is used.
Fix the two screws 42 that penetrate the side of the
It is also possible to screw the fixing fitting 44 onto the unit 4 and use the fixing member 44 to fix the floor joint material 40 on the unit 12 side where the partition 28 is present. In this case, the floor joint material 40 is slanted and guided to a predetermined position, and the fixing bracket 44 is positioned below the flange 22 of the beam 18 of the unit 12. Then two screws 4
When 2 is screwed in, the fixing bracket 44 moves upward and abuts the flange 22 as indicated by an imaginary line, and holds the flange 22 between the floor joint material 40 and the fixing bracket 44. On the unit 14 side, a screw 46 penetrating the side portion of the floor joint material 40 is screwed into the flange 22 of the beam 18.
