[0010]

[Embodiment of the invention]

 1 to 4 show an example of a cloth frame with a floor according to the present invention. In FIG. 1, a cloth frame with a floor 1 has a floor plate 3 on a cloth frame 2 and grips 4 at both ends in the longitudinal direction. And a stopper metal fitting 5 respectively.

The floor-mounted cloth frame 1 configured as described above pulls the gripping metal fittings 4 at both ends on a horizontal land 32 (hereinafter referred to as “horizontal land 6”) of a steel pipe scaffold as shown in FIG. 5, for example. It is stretched between each horizontal land 6,6. The cloth frame 2 bridges a beam 8 between both ends of two cloths 7 extending in parallel with each other, and also has a horizontal middle bar 10 between the middle parts of the cloths 7 and 7, and a beam 8. Between the intermediate portions, the vertical middle bars 9 are respectively bridged as necessary, and are formed in a plane rectangular lattice shape.

Note that the vertical center bar 9 is attached when the width of the cloth frame 2 is large (about 500 mm). Each of the cloth material 7 and the vertical middle bar 9 is formed in a substantially L-shaped cross section by bending the edge in the width direction of the floor plate 3 downward. The horizontal middle residue 10 is formed in a substantially L-shaped cross section, and is bridged between the cloth material 7 on both sides and the vertical middle crosspiece 9 or between the cloth materials 7, 7, respectively.

The beam member 8 is formed in a substantially groove-shaped cross section that opens right beside the inside of the cloth frame 2, and is continuously stretched between the end portions of the cloth material 7 on both sides and the longitudinal middle bar 9 therebetween. ing. In particular, a drop prevention stopper 11 protruding from the edge of the beam member 8 to a position above the horizontal land 6 is provided.

The fall prevention stopper 11 prevents the gripping metal 4 from being caught on the side ground 6 and falling even if the gripping metal 4 is erroneously removed from the end of the cloth material 7 due to long-term use. 6 to protrude to the approximate center of the horizontal land 6.

As the fall prevention stopper 11, for example, as shown in FIG. 2 (a), a horizontal flange 11a projecting horizontally from the upper end of the beam member 8 to the upper side of the cross ground 6 and supporting the horizontal flange 11a from below. And a plurality of vertical ribs 11b, or a bending process such that the edge 8a of the beam 8 projects above the horizontal ground 6 as shown in FIGS. 2 (b) and 2 (c). And others.

As described above, since the fall prevention stopper 11 protrudes from the edge 8 a of the beam member 8, the worker is working on the floor-mounted cloth frame 1 or the floor-mounted cloth frame. Even if the grip 4 is accidentally disengaged from the end of the cloth material 7 while walking on the floor 1 as shown in FIGS. 2 (d), (e) and (f), The fall prevention stopper 11 is hooked on the side ground 6, thereby preventing a fall accident of the worker.

Further, since the gap between the floor-attached cloth frames 1, 1 adjacent in the longitudinal direction is closed by the fall prevention stopper 11, parts such as bolts are accidentally dropped from this gap, or work is performed. It is possible to prevent an accident such as a member tripping over a gap and falling down. The floorboard 3 has the above-described cloth material 7 and the longitudinal middle crosspiece 9 at both edges in the width direction, and a plurality of reinforcing ribs 3a continuous in the longitudinal direction between them. The main purpose is embossing (irregular processing).

The grip 4 has a U-shaped engagement groove 4 a at the tip end thereof, which can be engaged with the horizontal ground 6 from above, and is formed in a plate shape by casting or forging, and the like. Are attached to both ends (each corner). Of the two grips 4 attached to one end of the cloth frame 2, one grip 4 is formed in a completely flat plate shape, and the other grip 4 projects from an end of the cloth material 7. Is slightly bent inward.

In this way, when the plurality of cloth frames 1 with floors are stretched between the horizontal lands 6 and 6 adjacent to each other in the longitudinal direction, for example, as shown in FIG. Therefore, the gap around the clamp 4 can be minimized.

The grip 4 is attached to the inside of both ends of the cloth material 7 by riveting, screwing, screwing or welding the base end. In this case, in particular, the gripping metal 4 projects so that the upper end thereof is substantially flush with the upper end surfaces of the cloth material 7, the beam member 8 and the floor plate 3, as shown in FIG.

In this way, there is no step on the floor surface or the passage constituted by the plurality of cloth frames 1 with the floor due to the grip metal 4 and the horizontal ground 6. For example, as shown in FIG. 4, the stopper metal fitting 5 includes a support metal fitting 12 and a drop lock 13 supported by the support metal fitting 12. The support fitting 12 is formed in a substantially groove shape in cross section, and is attached inside the beam member 8.

The falling tablet 13 is formed in a substantially crescent-shaped plate elongated in the circumferential direction of the horizontal ground 6, and is supported between the left and right flanges 12 a of the support bracket 12 by the upper support pin 14 and the lower support pin 15. In particular, the tip portion 13a protrudes from the slit 16 formed on the side of the beam member 8 toward the lower side of the horizontal ground 6.

The upper support pin 14 protrudes from the support fitting 12, the lower support pin 15 protrudes from the drop lock 13, and a guide hole 17 into which the upper support pin 14 and the lower support pin 15 are inserted. And 18 are formed on the drop lock 13 and the support fitting 12, respectively. The guide holes 17 and 18 are both formed as elongated holes in the longitudinal direction of the falling tablet 13. At the upper end of the inner hole 18, a guide hole 19 elongated in the direction perpendicular to the axis of the guide hole 18 is connected to the guide hole 18. Is formed.

With such a configuration, as shown in FIG. 4A, the falling tablet 13 moves over a certain range (the range of the length of the guide holes 17 and 18) in the circumferential direction of the horizontal land 6. In addition, it can protrude greatly from the slit 16 of the beam member 8 to the lower side of the horizontal ground 6.

As a result, while the cloth frame with floor 1 is stretched between the horizontal lands 6 and 6, the catches 4 are detached from the horizontal lands 6 because the falling tablets 13 protrude greatly below the horizontal lands 6. There is no. In addition, when the falling lock 13 is pushed into the beam member 8 and the end portion 13a slightly protrudes from the slit 16, the end of the floor-mounted cloth frame 1 is lightly pushed up, so that the gripping metal 4 can be easily moved from the horizontal ground 6. Come off.

Further, as shown in FIG. 4B, the falling tablet 13 rotates a fixed range (the length of the guide hole 19) to the side of the side ground 6 around the upper support pin 14 as a rotation axis, and the tip portion 13a Can protrude greatly from the slit 16 onto the horizontal ground 6. As a result, the falling lock 13 on the side where the grip 4 is removed from the side ground 6 is pushed into the beam member 8, and the tip 13 a is slightly protruded from the slit 16. Rotate the upper support pin 14 as a rotation axis to the side ground 6 side, pull it out, and lock it on the side ground 6 so that the side of the floor-mounted cloth frame 1 from which the gripping metal fittings 4 are removed is placed on the side ground 6. Since the floor frame 1 can be temporarily placed, the floor frame 1 can be easily removed from the horizontal ground 6 by simply pushing up the grip 4 on the opposite side without particularly supporting the cloth frame 1 with the hand. Therefore, the detachable floor frame 1 can be easily removed.

[0027]

[Effect of the invention]

 This invention is as explained above, especially since the both ends have grips that are locked to the side of the scaffolding frame, so that workers are working on the flooring frame, or Even if the grip is accidentally removed while walking on the road, the fall prevention stopper will be caught on the side ground to prevent the worker from falling down, which is extremely safe.

Further, the gap between the floor-mounted cloth frames adjacent to each other in the longitudinal direction is closed by the fall prevention stopper, so that components such as bolts are accidentally dropped from this gap, or the worker trips into the gap. Accidents such as falling down can be prevented beforehand.
