BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a temporary scaffold cover according to the present invention will be described with reference to FIGS.
[0009]
As shown in FIGS. 1 and 2, the temporary scaffolding cover 1 of the present embodiment is provided on a lower surface of the cover 2 for covering a gap between the floor-mounted cloth frames, and is provided on a lower surface of the cover 2. And one or a plurality of engaging portions 3 detachably engaged with the horizontal member.
[0010]
The cover 2 is formed in a substantially rectangular plate shape using a synthetic resin plate or a steel plate. The length of the short side of the cover portion 2 is formed to be larger than the interval between the adjacent floor-mounted cloth frames that are hooked on the horizontal member of the same building frame and arranged in tandem. The length of the long side of the cover 2 is formed to be substantially the same as the width of the floor-mounted cloth frame. The upper surface 20 of the cover portion 2 is a tread surface, and has many irregularities for preventing slippage.
[0011]
On the other hand, the engaging portion 3 is made of an elastic metal plate bent into a substantially C shape, and is configured by taking out a pair of curved engaging pieces 31 facing each other downward. The pair of engaging pieces 31 are formed so that the front end portions 32 of the pair of engaging pieces 31 are narrower than the middle portion as a retaining means for the horizontal member of the building frame. Thus, the engaging portion 3 can elastically grip the lateral member of the building frame with the pair of curved engaging pieces 31 so that the engaging member 3 does not easily come off from the lateral member. The engaging portion 3 is screwed downward at the base end portion 30 to the lower surface of the cover portion 2 to form the temporary scaffolding cover 1.
[0012]
In the present embodiment, as shown in FIG. 2, the pair of engaging portions 3 is disposed near both ends in the long side direction of the cover portion 2, but the engaging portion 3 is provided only at the center of the cover portion 2. For example, various design changes can be made to the arrangement position, the number of arrangements, and the like of the engaging portions 3.
[0013]
As shown in FIG. 3, the temporary scaffold cover 1 according to the present embodiment is configured such that the hooks H are hooked on the horizontal members G of the building frames F and the two floor-mounted cloth frames P are arranged in a tandem state. When the engaging portion 3 is engaged with the horizontal member G of the building frame F from above, the pair of curved engaging pieces 31 of the engaging portion 3 elastically deform the horizontal member G as shown in FIG. Thus, the lower surface of the long side portion of the cover portion 2 covers the gap S between the floor-attached cloth frames P in a state where the lower surface of each of the long sides of the cover section 2 is in contact with the upper surface of the floor-mounted cloth frame P.
[0014]
As described above, the temporary scaffold cover 1 of the present embodiment is provided on the lower surface of the cover portion 2 formed so as to be larger than the interval between the adjacent floor-mounted cloth frames P, to engage with the horizontal members G of the building frame F. Since the portion 3 is provided, the gap S between the floor-attached cloth frames P can be closed by only a very simple operation of engaging the engaging portion 3 with the horizontal member G of the building frame F. There is no danger of dropping work tools and materials from the gap S, and the gap S prevents the worker from stepping on the floor-mounted cloth frame P or tripping over, thereby further improving work safety. Can be.
[0015]
Further, in the present embodiment, the short side of the cover portion 2 is formed to be larger than the interval between the adjacent cloth frames P with a floor, and the lower surface of the long side portion of the cover portion 2 is attached to the cloth frame P with a floor when the cover is attached. Since it is in contact with the upper surface, it is possible to prevent the cover portion 2 from being depressed by a load, and at the same time, it is possible to reduce the load on the engaging portion 3 and improve the strength of the temporary scaffold cover 1. .
[0016]
Moreover, in the present embodiment, since the engaging portion 3 is provided with a retaining means for the horizontal member G, the temporary scaffold cover 1 can be securely and stably mounted on the horizontal member G of the building frame F. Needless to say, the lower surface of the cover portion 2 comes into contact with the upper surface of the floor-mounted cloth frame P, so that the floor-mounted cloth frame P itself also serves to hold. Therefore, for example, the vibration and fluttering of the floor-mounted cloth frame P due to the walking of the worker can be suppressed, and also in this respect, the work safety can be improved.
[0017]
Furthermore, in the present embodiment, the engaging portion 3 is made of a substantially C-shaped elastic metal plate material, and the distal end portion 32 side is formed narrower than the middle portion. It is possible to realize an engaging portion provided with a stopping means, and it is possible to provide a very inexpensive temporary scaffold cover 1 to the market.
[0018]
Although the embodiment of the temporary scaffold cover according to the present invention has been described above, the present invention is not limited to the above-described embodiment, and various design changes are possible.
[0019]
For example, in the above-described embodiment, the short side of the cover portion 2 is formed to be longer than the interval between the adjacent floor-mounted cloth frames, and the lower surface of the cover section 2 is brought into contact with the upper surface of the floor-mounted cloth frame when the cover is attached. Although the gap between the attached cloth frames is covered, it is sufficient that the gap can be substantially closed by the cover. For example, as shown in FIG. The temporary scaffold cover may be fitted into the gap between the floor-mounted cloth frames so as to have a length substantially equal to the interval between the frames. At this time, as shown in FIG. 5, it is also possible to form the cover portion 2 so that the cover upper surface 20 is flush with the upper surface of the cloth frame P with floor when the cover is attached. Further, the long side of the cover part 2 is set to be approximately twice as long as the width of the floor-mounted cloth frame P so as to simultaneously close the gap between the two floor-mounted cloth frames arranged in parallel on the horizontal member of the building frame. You may do it.
[0020]
Further, in the above-described embodiment, the pair of curved engagement pieces 31 is taken out to constitute the engagement portion 3 provided with the retaining means. For example, as shown in FIG. Alternatively, the engaging portion 3 provided with the retaining means may be constituted by a pair of linear engaging pieces 33 inclined narrowly. In this case, the cover portion 2 is always urged downward by the pair of inclined linear engagement pieces 33, so that the mounting stability of the cover can be improved.
[0021]
Further, as shown in FIG. 7, the engaging portion 3 may be constituted by an engaging piece 34 having an insertion opening formed on the side by a bent piece 35 on the distal end side. In this case, when attaching the cover, the engaging piece 34 of the engaging portion 3 is inserted between the horizontal member G of the building frame and the cloth frame P with the floor, and then the cover is slid sideways. The joint 3 is engaged with the horizontal member G.
[0022]
Further, as a means for preventing the engagement portion 3 from coming off, it is a matter of course that a well-known screwing mechanism may be employed. For example, as shown in FIG. A well-known screwing mechanism that fixes the moving end with a bolt piece 37 and a nut 38 that are also pivotally supported by a pin may be used.
[0023]
In the temporary scaffold cover according to the present invention, it is not always necessary to provide the engaging portion 3 with a retaining means. For example, as shown in FIG. May be formed in the engaging portion 3 so that the horizontal member G is simply engaged with the concave portion 39.
[0024]
Further, in the above-described embodiment, the example in which the temporary scaffolding cover is attached to the horizontal member G of the building frame F that forms the framework scaffold, which is a kind of scaffold, is of course limited to the present invention. Rather than, for example, a brace that is a cross member in a single pipe scaffold, an overhang material that is a cross material in an overhang scaffold, a bracket cross material of a bracket on one side scaffold, a cross material of a movable scaffold, To improve work safety by closing the gaps between floor-mounted fabric frames hooked on these types of scaffolds, such as girders, which are horizontal materials for hanging frame scaffolds. Can be.
[0025]
【The invention's effect】
The temporary scaffold cover according to the present invention includes a cover portion that closes a gap between the floor-mounted cloth frames hooked on the horizontal member of the scaffold, and the cover portion detachably engages with the horizontal member of the scaffold. Since the engaging portion is provided, the gap between the floor-attached cloth frames can be closed with only a very simple operation of engaging the engaging portion with the horizontal member, and the working tools and materials can be closed from the gap. There is no danger of dropping, and the safety of the work can be further improved without the worker stepping on the floor-mounted cloth frame or falling over in the gap.
[0026]
In addition, when the lower surface of the cover is brought into contact with the upper surface of the cloth frame with the floor when the cover is mounted, the cover can be prevented from being depressed by a load, and the load on the engaging portion can be reduced. In addition, the strength of the temporary scaffold cover can be improved.
[0027]
Furthermore, if the engaging portion is provided with a retaining means for the cross member of the scaffold, the temporary scaffold cover can be surely and stably attached to the cross member, and furthermore, the cover portion can be fixed. If the lower surface is brought into contact with the upper surface of the floor-mounted cloth frame, the temporary scaffold cover also serves to hold and hold the floor-mounted cloth frame. Can also be suppressed.
