Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary veranda step which can enter and exit between a temporary scaffold and a veranda at a construction site.

[0002]

2. Description of the Related Art Conventionally, a temporary scaffold has been installed around a building when performing construction work outside the building. Then, tools and materials to be used for the construction work are arranged in advance around the temporary scaffold, thereby improving work efficiency. For example, in the construction of the first floor of a building, tools and materials are placed on the ground, but especially for the construction of the second floor or more,
Tools and materials are placed inside each floor. Therefore, in order to invade the inside of each floor from the temporary scaffold through the veranda, in the related art, directly invade the inside of the veranda directly from the temporary scaffold, or as shown in FIG. They had to pass it and set up a passage.

[0003]

However, if the worker walks directly into and out of the veranda from the temporary scaffold, an accident of the worker falling easily occurs, which is extremely dangerous. Also, there is a great risk of dropping tools and materials when going in and out. Moreover, if the user directly enters and exits the veranda, the veranda itself may be damaged.

On the other hand, as shown in FIG. 3, when a stepladder is installed inside a veranda and a scaffold plate is passed between the stepladder and a temporary scaffold, a certain degree of safety is enhanced as compared with a case where the person steps in and out directly. However, since the scaffold is simply placed on the stepladder, there still remains the danger of getting in and out when moving from the temporary scaffold to the scaffold, or when raising or lowering the stepladder. .

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is very safe and easy to enter and exit the veranda, and furthermore, a temporary veranda step capable of preventing damage to the veranda itself. The purpose is to provide.

[0006]

In order to achieve the above object, a first means of the present invention is to provide a cross member P of a temporary scaffold P.
1, a deck 2 extending substantially horizontally into the veranda Q from the connector 1, and a deck 2
And a step body 3 that extends and inclines to the floor surface of the veranda Q.

The second means is to connect the cross member P1 of the temporary scaffold P to which the connecting member 1 is connected to the cross member P1 located beside the cloth plate R below the cross member P1, and A ladder body 4 forming a ladder step 4A is provided between the ladder body 4 and the deck body 2.

The third means is to provide a handrail body 5 from the deck body 2 to the step body 3 as means for solving the problem.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

According to the present invention, a temporary scaffold P installed around a building is attached to a veranda Q when a construction work outside the building is carried out. It has a body 2 and a step body 3.

The connecting body 1 is connected to the horizontal member P1 of the temporary scaffold P. In the illustrated example, a pair of locking hooks 1A having a substantially C-shaped side surface are provided on the side surface of the deck body 2. As the cross member P1 to which the connecting body 1 is locked, the handrail of the temporary scaffold P is used. Instead of the handrail, the cross member P1 is connected to the cross member P1 laid side by side with the cloth plate R. You may stop.

The deck body 2 extends substantially horizontally from the connecting body 1 to the inside of the veranda Q, and is installed above the veranda Q. The deck 2 is provided with a handrail 5 to facilitate walking of the deck 2. The illustrated handrail body 5 is provided from the deck body 2 to a step body 3 to be described later, and a support column 5B is inserted into a support tube 5A provided on the side surface of the deck body 2 and the step body 3 to stand upright. Further, the stopper 5C penetrating the support tube 5A and the column 5B prevents the support tube 5A from being pulled out (see FIG. 1). At this time, a pair of handrails 5 are provided on the left and right sides of the deck body 2, but the handrails 5 may be provided on only one side depending on the situation.

The step body 3 is extended from the deck body 2 to the floor of the veranda Q while being inclined.
It is foldably connected to the side of. The illustrated step body 3 includes a pair of connecting pieces 3 </ b> C provided at the end of the deck body 2.
The slide legs 3B are swingably connected to each other, and a plurality of steps 3A are provided between the slide legs 3B. The slide leg 3B is pivotally mounted on the connection piece 3C with a swing shaft 3D, and a rotation stopper 3E penetrating the slide leg 3B in use is inserted into the connection piece 3C. Further, the length of the slide leg 3B is made adjustable by fixing the length of the slide leg 3B that has been slid by a slide lock 3F penetrating the slide leg 3B.

Reference numeral 4 denotes a ladder body 4, and the ladder body 4
Is connected from the horizontal member P1 of the temporary scaffold P to which the connecting member 1 is connected to the horizontal member P1 located beside the cloth plate R below the horizontal member P1, and between the cloth member R and the deck body 2. Is formed with a plurality of ladder stages 4A. In the embodiment, a ladder step 4A is provided on a pair of right and left columns 4B, and this column 4B is connected to an upper horizontal member P1 serving as a handrail and a lower horizontal member P1 arranged along the side surface of the cloth board R. ing. At this time, the fixed clamp 4C fixed to the upper part of the column 4B is connected to the cross member P1, and the column 4B
The upper and lower clamp positions are adjusted by connecting a slide clamp 4D slidably provided at the lower part of the support 4B to the support 4B to prevent the support 4B from rolling. The ladder body 4 is set in accordance with a preset height of the cloth plate R and a height of the veranda Q when the wedge-type temporary scaffold P is used. In addition, when using a temporary scaffold P of another type and the cloth board R is installed at the height of the veranda Q, the mounting of the ladder body 4 may be omitted (not shown). .

[0015]

According to the present invention, the above-mentioned configuration achieves the original object.

That is, according to the first aspect of the present invention, it is possible to prevent a worker from falling down and to safely enter and exit the veranda. In addition, since the user can enter and exit without touching the veranda Q, it is possible to prevent the veranda itself from being damaged.

Further, according to the second aspect, it is possible to easily move up and down from the cloth plate R of the temporary scaffold P to the upper part of the veranda Q.

Furthermore, the handrail body 5 according to the third aspect of the present invention is extremely easy to move, so that it can be moved without dropping tools and materials. Further, the deck body 2 and the step body 3 during use can be securely fixed.

As described above, according to the present invention, there are various useful effects such as extremely safe and easy access to the inside of the veranda and prevention of damage to the veranda itself.
