DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for installing a waterproof sheet in building construction.

[0002]

2. Description of the Related Art Conventionally, when a waterproof sheet is attached around a building at a construction site, at least two persons are provided on a scaffold plate, and one person holds the waterproof sheet in a direction perpendicular to the building. Because the method of stitch stop work was widely adopted by one person, it was troublesome and could not be carried out quickly, and it was in a stuck state where rainwater easily penetrated.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention eliminates such disadvantages and allows a single person to quickly and reliably mount a waterproof sheet in the horizontal direction without trouble, while at the same time allowing rainwater to be removed. It is an object of the present invention to provide a construction method and apparatus capable of completely preventing intrusion.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a suspension member is suspended on a hanger rail erected above a building under construction so as to be movable in a lateral direction, and a waterproof sheet mounting member is attached to the suspension member. This is a construction method in which the waterproof sheet mounting device is stopped at an arbitrary height around the building by a brake provided on the suspension member, and a roll-shaped waterproof sheet prepared for the waterproof sheet mounting device is laterally stretched.

Further, according to the present invention, a hanger rail is erected laterally on an upper portion between columns temporarily provided around a building, and a balancer housing provided with a moving wheel is hung on the hanger rail, and a hanger rail is provided. A rope is wound around a drum provided inside and a brake is also provided, and a waterproof sheet attachment is provided at the lower end of the rope so that a waterproof sheet attachment can be attached and detached. It is a device to be stuck.

Further, according to the present invention, a hanger rail is erected laterally on an upper portion between the columns of a building, and a balancer housing provided with moving wheels is hung on the hanger rail, and the hanger rail is hung inside the housing. A chain is wound around the provided wheel and a brake mechanism is also provided.A waterproof sheet attachment is provided at both ends of the chain so that a waterproof sheet attachment can be attached to and detached from the chain. It is a device to be mounted.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the apparatus according to the second aspect, the following operation is performed. (See FIGS. 1 to 7)

When the wire rope is pulled up, the drum and the clutch rotate at the same time, so that the wire rope is wound up by a coil ammunition built in the balancer housing. However, the weight of the waterproof roll sheet changes between before and after use. The braking action of the brake wire is preliminarily adjusted by an adjusting screw so as to balance the load within a certain load range (for example, 5 to 10 kg).

When the wire rope is pulled down, the clutch and the brake wheel are integrated and idle with the wire, so that the braking action is adjusted in advance by adjusting screws.

When the waterproof roll sheet is attached to and detached from the upper movable shaft and the lower fixed shaft, the adjusting screw is relaxed so that the upper tube is pulled up from the lower adjusting rod. Can be detached from the upper end of the roll sheet and can be directly removed, and can be mounted by performing the reverse operation.

The above-described work of raising and lowering the wire rope is performed on the scaffold when the scaffold is installed around the building, but is performed inside the building when the scaffold cannot be installed.

According to the third aspect of the invention, the following operation is performed. (See FIGS. 9 to 16)

[0013] In the case of new construction work in a densely built area, it is difficult to temporarily set up a scaffold, and an operator must attach a waterproof sheet inside the building. Attach the brackets and install the hanger rail between the brackets.

Thereafter, a roll bracket is hung on the hanger rail via a hanger roll, and the hanging portion of the chain wheel bracket is connected to the roll bracket and fixed.

The chain wheel bracket is provided with a chain wheel case with a built-in chain, and a waterproof sheet attachment is attached to both ends of the chain suspended on the chain wheel.

When attaching a waterproof sheet, a chain attachment is attached to a predetermined place in the building by operating a chain from the inside of the building, and the roll sheet is stretched in the lateral direction and stretched. It is.

The vertical movement of the seat fixture by operating the chain causes the chain wheel to rotate together with the one-way clutch.

When attaching and detaching the waterproof roll sheet between the upper movable shaft and the lower fixed shaft, the adjusting screw is relaxed so that the upper tubular body is pulled up from the lower adjusting rod. Can be detached from the upper end of the roll sheet and can be directly removed, and can be mounted by performing the reverse operation.

When a waterproof sheet is stretched around a building under construction, a single worker can quickly and reliably stretch a plurality of steps in the lateral direction, and a short time is required. The work of mounting the seat can be performed at home. Therefore, the construction cost is also reduced.

The installation of such a waterproof sheet is ensured not only when a scaffold is temporarily provided around the building but also in a densely populated area of a building where there is no space for installing the scaffold, by extending a hand from the room. Will be able to

Since the waterproof sheet is attached in a number of steps in the horizontal direction around the building, a gap due to the overlapping between the sheets cannot be formed on both the left and right sides, and rainwater enters the inside from the horizontal direction. Can be reliably prevented.
