DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a flooring fabric to a temporary scaffold for various types of construction work, and to a flooring fabric.

[0002]

2. Description of the Related Art Conventionally, a structure shown in FIG. 5 has been known as a mounting structure for a floor-attached fabric in a temporary scaffold of this type, which will be described with reference to FIG. 1 is a post made of a metal pipe having a required height constituting a required temporary scaffold, and 2 is a substantially tapered staggered upper outer peripheral surface of the post 1 at a predetermined interval.
These are four substantially U-shaped locking metal fittings that are fixed so as to form a pa-shaped locking hole. Numeral 3 is a bracket which can be laid horizontally on the column 1, and the bracket 3 is formed in a substantially right triangular shape by a horizontal member 4, an oblique member 5 and a vertical member 6. Numeral 7 denotes wedge-shaped locking pieces respectively attached to both ends of the horizontal member 4 so as to be fitted and locked to the locking metal fitting 2, and 8 denotes one end of the oblique member 5 to be brought into contact with the outer peripheral surface of the column 1. It is a mounted piece. 9 is the bracket 3
Fabric with a floor that can be freely mounted between the columns 1 through
Reference numeral 0 denotes a floor material made of expanded metal, surface-treated steel plate, or the like having a required width and length that constitutes the floor-attached fabric 9. Reference numeral 11 denotes a stiffener on both side edges of the floor material 10 along the longitudinal direction thereof. A cross-section substantially U-shaped cloth material with a pair of hooking steps 12 attached on both sides attached via materials (not shown), 13 is the floor material 10
The tension members 13 are formed in the same shape as the cloth material 11, respectively. Reference numerals 14 denote fittings respectively attached to both ends of each tension member 13 so as to be gripped by the horizontal member 4.

In the conventional example constructed as described above, a required number of columns 1 are self-supported side by side at predetermined intervals in parallel, a locking piece 7 is fitted and locked to a locking metal fitting 2 and a contact piece 8 is provided. After the bracket 3 is laid horizontally between the adjacent columns 1 while applying the above, the metal fittings 14 are gripped by the horizontal member 4, and the cloth 9 with a floor is erected between the corresponding brackets 3, and sequentially upward. The temporary scaffold is constructed by connecting and attaching required scaffold members such as stairs and handrails to predetermined locations (see FIG. 6).

[0004]

However, the prior art constructed as described above has the following drawbacks because the floor-attached fabric 9 is erected between the columns 1 via the brackets 3. Things. First of all, since the bracket 3 is always required when the floor-attached fabric 9 is erected, the bracket 3 must be manufactured separately and independently, and as a result, the number of parts of the scaffold member increases, This is not only inconvenient for transportation and storage, but also increases the cost as a whole. Secondly, since the cloth 3 with the floor is erected through the bracket 14 after the bracket 3 is laid horizontally between the columns 1, the operation is very troublesome and time-consuming, and the locking is also required. The locking piece 7 is fitted and locked to the metal fitting 2, and at the same time, the hook metal fitting 14 is gripped by the horizontal member 4, so that the column 1 and the bracket 3 are held.
-Since the floor-attached fabrics 9 are connected to each other, the rigidity against the rotational force in the horizontal plane is low, and the floor-attached fabrics 9 are easily rattled, and it is difficult to construct a strong scaffold. Third, since the floor-attached fabric 9 must be erected through the bracket 3, the width of the floor-attached fabric 9 cannot be increased inevitably, and the working floor becomes narrower. There is a possibility that an unexpected accident such as falling of an article may be caused.

[0005] Further, in the fabric 9 with floor,
As shown in FIG.
3 is formed by processing a sheet metal into a substantially U-shaped cross section having a hooked step portion 12, so that not only is it very troublesome and troublesome to manufacture, but also the cost is high, and Low in rigidity and not always satisfactory in strength.

SUMMARY OF THE INVENTION The present invention solves the problems of the prior art at a glance, and makes it possible to quickly and surely and firmly attach a floor-attached fabric directly to a support without interposing a horizontal member such as a bracket. It is an object of the present invention to provide a structure for attaching a floored fabric to a temporary scaffold.

It is another object of the present invention to provide a floor-attached fabric which is not only inexpensive and can be easily manufactured but also has high rigidity and very large strength.

[0008]

That is, the first invention of the present application is to provide a column 1 which is free standing in parallel at a predetermined interval.
In order to construct a required temporary scaffolding by laying a cloth 51 with a floor therebetween, each of the columns 1 is provided with an engaging metal fitting 2 on its outer peripheral surface in an upward direction. The mounting structure of a floor-attached fabric in a temporary scaffold is characterized in that locking pieces (56) are provided at four corners at both ends of a floor-attached fabric (51) so as to be stopped and installed. It is. In the first invention, the locking piece 56 is fitted and locked to the locking metal fitting 2 without the need for a horizontal member such as the bracket 3 as in the conventional example, thereby providing the floor-mounted fabric 51. Can be directly attached to the column 1 and erected.

In the second invention of this application, a pair of cloth materials 53 are provided on both side edges of a square flooring material 52 having a required width and length, respectively. Are provided with a pair of tension members 55, and mounting members 56 are provided at both ends of the floor member 52, respectively.
In 1, the at least the cloth material 53 is formed of a pipe material processed into a required shape, and is characterized by a cloth with a floor. In the second invention, since at least the cloth material 53 is formed by a pipe material processed into a required shape, not only can it be manufactured easily and at low cost, but also it can be manufactured at low cost.
It is possible to obtain a floor-mounted fabric 51 having high rigidity and very large strength.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to an embodiment shown in FIG. Reference numeral 51 denotes a flooring fabric formed to have substantially the same width as the width when the columns 1 are self-supported in parallel, and 52 denotes a floor material made of an expanded metal, a surface-treated steel plate, or the like constituting the flooring fabric 51. , 53 are a pair of hanging material 54 with a pair of hanging steps 54 attached to both side edges of the floor material 52 along the longitudinal direction thereof via stiffeners (not shown), and the fabric material 53 is made of metal. It is formed by pressing a pipe material (see FIG. 4). 55 is a pair of metal pipe tension members attached to both ends of the floor material 52, respectively, and 56 is downwardly formed on both ends of the two-sided cloth material 53 so as to be fitted and locked to the locking fittings 2 of the column 1. Approximately wedge-shaped locking pieces, 57 are tension members 55 at both ends
Are small-width auxiliary flooring materials respectively extended to each other. Other parts are the same as those of the conventional example, and the same reference numerals indicate the same parts.

In the embodiment constructed as described above, the required number of columns 1 are made to stand by themselves at predetermined intervals in parallel, and the locking pieces 56 are fitted and locked to the corresponding locking fittings 2. The floor-attached fabric frame 51 is directly mounted between the adjacent struts 1 and erected, and sequentially connected upward, and a temporary scaffold is constructed by attaching a scaffolding member such as a stair or a handrail at a predetermined location (FIG. 2 / FIG. 2). 3). At this time, the cloth frame 51 with the floor is attached to the bracket 3 as in the conventional example.
Since the locking piece 56 is fitted and locked to the locking metal fitting 2 and can be directly mounted on the support 1 and erected without requiring the mounting work, the mounting work can be performed easily, quickly, and reliably. Not only can this be performed, but also the rigidity of the erected floor-attached fabric frame 51 against the rotational force in the horizontal plane is very high, and there is no possibility of rattling. Further, as described above, since a horizontal member such as the bracket 3 is not required, the width of the floor-attached frame 51 is formed to be wide as shown in FIG. 2 to effectively prevent unexpected accidents such as dropping of articles. I can do it. Further, the floor frame 51 itself, its cloth material 53 and tension material 55
Are each formed of a pipe material, and thus have extremely high rigidity and extremely high strength.

Conversely, when dismantling a temporary scaffold,
By pulling out the locking piece 56 from the locking metal fitting 2, the floor frame 51 is removed, and the disassembly work can be easily performed.

In the above embodiment, the locking fitting 2 is formed in a U-shaped cross section. However, the present invention is not limited to this. The locking fitting 2 may be formed in a substantially tapered cylindrical shape or the like. Furthermore, the cloth material 53 and the tension material 5 that constitute the floor frame 51
5 is made of a metal pipe material, but at least a cloth material 53 is used in view of strength and cost.
The object of the present invention can be effectively achieved even if only the metal pipe material is used, and the invention can be applied to other known fabrics with floors.

[0014]

According to the present invention, when a required temporary scaffold is constructed by erection of a cloth 51 with a floor between the columns 1 which are self-standing in parallel at predetermined intervals, as described above. Locking fittings 2 are provided on the outer peripheral surface of each support column 1 in an upward direction, and locking pieces 5 are provided at the four corners at both ends of a floor-attached fabric 51 so as to be fixed to the locking fittings 2 and erected.
6 is provided in a downward direction, so that the locking piece 56 is fitted and locked to the locking metal fitting 2 without a need for a horizontal member such as the bracket 3 unlike the conventional example. In this way, the floor-attached fabric 51 can be directly attached to the column 1 and erected, so that the installation work can be performed very easily, quickly and reliably, and also the erected floor-attached fabric is installed. 51 has a very high rigidity against a rotational force in a horizontal plane, and thus can always be firmly attached without rattling. Further, since the bracket 3 can be directly attached without the need for the bracket 3 as described above, not only can the cost be reduced as a whole, but also the width of the floor-mounted cloth frame 51 itself can be reduced as compared with the conventional example. This makes it possible to effectively prevent unexpected accidents such as falling articles.

Further, since at least the cloth material 53 constituting the floored fabric frame 51 is formed of a pipe material processed into a required shape, the rigidity is extremely high as compared with the conventional example.
Not only has high strength, but it can be manufactured easily and at low cost.
