Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a protective handrail for temporary scaffolding that can be hung on a temporary scaffolding at a construction site.

[Problems to be solved by conventional techniques and devices] Although there are various structures and materials to hang a scaffold temporarily installed on a construction site, there is a risk of crashing in the outer scaffold and the stairwell part made of steel pipe, etc. In order to prevent such problems, wire mesh and double pipe structure scaffolds have been used conventionally.

However, such protective measures are too expensive and inconvenient for the work. Furthermore, when the outer surface of the building becomes, for example, a stairwell surface or when there is a bay window, the distance between the scaffolding and the outer wall of the building is too far or too close to be able to handle it. It was

SUMMARY OF THE INVENTION In the above situation, the present invention aims to provide a protective handrail which protects the danger of a fall and prevents the danger of an operator on a temporary scaffold, and at the same time does not make the work inconvenient. Therefore, an object of the present invention is to provide a protective handrail for temporary scaffolding, which is easy to handle and low in cost, on a work floor of the temporary scaffolding.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides clips (5) for attaching to a support member (6, 7, 8 etc.) of a temporary scaffold at both ends thereof. An elastic rope member (2) provided at both ends thereof at appropriate suitable supporting members,
At both the temporary footboard (4) and the end rod, at appropriate appropriate positions,
It has a protective net member (1) having rectangular eyes attached by an elastic band (3), the protective net member (1) having such a size that the rectangular eyes can work through the eyes. Furthermore, there is provided a protective handrail for temporary scaffolding, which is made of an elastic material. The elastic material protection net member (1) is preferably made of elastic plastic or hard rubber, and the elastic rope member (3) is preferably made of a plastic elastic member or a rubber body. As the support member for the temporary scaffold, a vertical pipe member, a horizontal pipe member, a scaffold blanket, a corner portion pipe member, and the like.

[Operation] The handrail of the present invention has a structure in which a lightweight and durable protective net member is used, and work can be performed through the net eyes. Furthermore, the handrail is reinforced and held by a rope member made of an elastic body, and the lower end is It is a work floor handrail with an assembly method that is held by a scaffolding work floor bracket. Therefore, by adjusting the place where the rope member is stretched, that is, the place where the rope member is fixed to the pipe of the temporary scaffold, the position is adjusted or corresponded to the distance between the outer wall and the outer surface of the building. You can

The protective net member for temporary scaffolding of the present invention is preferably made of elastic plastic or rubber. As the plastic material, a polymer forming an elastic body such as polybutylene resin or polybutadiene resin can be used.

Further, as the rope member, a usual rubber or plastic rope for construction can be used. And
It is also preferable that a clip is attached to an end portion of the scaffold pipe for temporary installation so that the clip can be fixed, and a spring-loaded return preventing mechanism is provided so that the clip does not come off when the pipe is gripped.

Further, as the rubber band used for fixing the protective net member, the same one as that normally used for fixing the scaffolding plate can be used.

Further, the assembly of the holding rope member and the protective net member arranged side by side can be used by fixing the rope member to a steady rest, for example, a bracket of a scaffolding pipe, in order to prevent a risk of swinging or shaking.

As described above, the protective handrail for temporary scaffolding of the present invention has the net member as the main constituent member and does not interfere with the operator.
It can prevent the risk of a fall, and can be used not only as a temporary scaffold, but also as a sacks for fall prevention in general.

Next, the protective handrail for temporary scaffolding of the present invention will be described with reference to an example applied to a temporary scaffold used in a construction site of a private house, but the present invention is not limited thereto.

[Example] As shown in the perspective view showing the usage mode of Fig. 1, the protective handrail for temporary scaffolding of the present invention has pipe members 7, 8 for constructing a building 10 as shown by a dotted line, for example. Stand up
Further, the pipe member 9 is also assembled in the lateral direction, and the scaffold bracket 6 is installed on each of the pipes 7 and 8, and the temporary scaffold tread (mesh plate) 4 for the operator is installed as illustrated. There is.

Therefore, the rectangular protective net 1 according to the present invention is fixed as shown. That is, the four corners of the rectangular protective net 1 are tied and fixed by the rubber bands 3.

As shown in the figure, the protective net 1 is a net having a size that does not hinder the work. That is, in this case, the size of the net is 90 cm × 180 cm as shown in the drawing, and the nets are about 45 cm square. An operator can easily reach the wall surface, the sash frame, and the like from the net having such a size by extending his hand.

Further, the rope member 2 is fixed between the temporary scaffolding pipes 8 by the clip members 5 at the ends thereof by utilizing its elasticity. To the rope member 2 pulled and fixed, the protective net 1 is attached to the rubber band 3 as shown in the explanatory view of FIG.
Tie it together and fix it. Furthermore, the lower end of the protective net 1
As shown in FIGS. 1 and 2, the end portions of the scaffolding tread 4 are tied together with the rubber band 3 as shown in FIGS.

This rope member 2 usually comes in two types, 3m and 4m, can be adapted to the scale of the construction site, and the clips on both ends mentioned above can be used so that they can be connected to each other.

Further, next, another protective net 1 is arranged along the ends of the rope member 2 and the scaffolding tread 4 as shown in FIG. 1, and its four ends are connected to the ends of the rope member 2 and the scaffolding floor 4. Attach it to the part with the rubber band 3 and fix it.

As such a rubber band, a conventionally used rubber band for fixing a building scaffolding plate can be used.

In this way, and as shown in FIG. 1, the protective net can be laid on the work plate 4 to construct a structure that functions as a handrail. Therefore, the height of the handrail is 90 cm,
As shown in the figure, at the corners of the scaffolding, other horizontal pipe members are attached and fixed in four directions.

Further, in the blow-through portion of the building, the protective net member can be directly fixed to the pipe by using the rubber rope member. Furthermore, in the bay window portion, the steady rests of the rope members can be fixed and stretched on both sides of the vertical pipe member 8 for the bay window portion.

This temporary scaffolding handrail protects the worker from the risk of falling and does not require the worker to have a safety belt.

Further, since it is made of rubber or plastic and has elasticity, but is a strong material, it does not hinder the work and is sufficiently effective in preventing the worker from falling.

Further, each member used in the handrail of the present invention is made of materials such as a protective net, a rope member, and a rubber band that have been conventionally used in a normal construction work site. Has been confirmed not to occur.

Assembled in this manner, the present invention can provide a fall prevention handrail to the work floor of the scaffold.

[Effects of the Invention] The temporary scaffolding protective handrail according to the present invention has the following technical effects by being configured as illustrated.
That is, firstly, it provides a guard handrail that protects the risk of a fall on a temporary scaffold and prevents the risk of the worker, and at the same time does not make the work inconvenient.

Secondly, we provided a protective handrail for temporary scaffolding on the work floor of temporary scaffolding, which is easy to handle and easy to use.
