Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet stretching apparatus to be attached to a pillar in a building or the like.

[0002]

2. Description of the Related Art Conventionally, a sheet (including a waterproof sheet) having a predetermined width wound, for example, in a roll shape is attached to a roof or a pillar inside a wall. On this sheet, a metal mesh called a metal lath and a wire lath used as a base when applying mortar or plaster is attached, and the mortar or plaster is applied to the metal mesh to form a wall.

[0003] An assistant holds the sheet body on which the sheet is wound, and another person pulls out one end from the sheet body and attaches it to a roof or a pillar inside a wall. In such a case, a scaffold assembled with a plurality of pipes is installed around the building at the building site. This scaffold was installed at a predetermined distance from the pillar so that work on the wall around the building could be easily performed, and the assistant held the seat body on the scaffold.

Further, as another person sticks to the pillar inside the roof or the wall, the assistant moves while holding the wound sheet body, and the wound sheet is thereby moved to the roof or the wall. It is stretched on inner pillars. Such a sheet had a width of about 1000 mm and an outer diameter of about 160 mm, and was heavy at about 10 kg to 20 kg. That is, since the sheet is heavy and cannot be stretched while holding the sheet body alone, the person stretching the sheet and the assistant holding the sheet body stretch the sheet.

[0005]

However, when a sheet is stuck to a roof or a column inside a wall, a person who sticks the sheet to a column inside the roof or a wall and an assistant who holds the sheet body are inevitable. And had to do it. For this reason, at least two people are required to stretch the seat, and there has been a problem that the cost of stretching the seat increases.

Further, the roof is generally provided with a predetermined slope, and there is a risk that an assistant holding a heavy sheet body at the edge of the roof may fall off the roof. .

Further, when the sheet is attached to a pillar inside a wall, particularly when the sheet is attached outside a pillar around a building,
The assistant held the seat body on a scaffold placed at a predetermined distance from the pillar. Therefore, the assistant must hold the heavy seat body away from the body, and there is a problem that holding the seat body greatly increases the fatigue of the waist and shoulders.

[0008] Therefore, even when a sheet is stuck on a roof or a pillar inside a wall, there has been a demand for the development of a sheet stitching apparatus capable of reducing the fatigue of the waist and shoulders and setting the sheet by itself.

The present invention has been made in order to solve the above-mentioned conventional technical problems, and is a sheet capable of performing work safely even on an architectural scaffold, and capable of seating alone. It is intended to provide a tensioning device.

[0010]

That is, a sheet stretching apparatus according to the present invention is provided with a main body having a size that can be inserted into a cylinder wound with a sheet used in construction or the like, and an end of the main body. Handle portion, an opening formed in the handle portion, which can be hooked on an architectural scaffold, a plate-like stopper rotatably inserted into the main body, and a detachably attached to the main body, and the stopper is provided on the main body. Fixing means for preventing movement to the other end side.

Further, in the sheet stretching apparatus according to a second aspect, in addition to the first aspect, the fixing means is constituted by a plurality of nuts screwed to the main body.

Further, in the sheet stretching apparatus according to a third aspect, in addition to the first aspect, the fixing means is constituted by a pin inserted into the main body.

Further, in the sheet stretching apparatus according to the fourth aspect, in addition to the first, second or third aspect, a supporting portion is provided at the other end of the main body.
