Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple temporary roof that opens and closes during construction of a steel frame body in construction work.

[0002]

2. Description of the Related Art Temporary roofs of all-weather type, which are erected during the construction of buildings so that they are not affected by the weather, vary depending on the scale and shape of the building in order to improve the recent working environment and prevent construction delays. It came to be implemented by various structures and construction methods. For example, the roof rises and the roof is partially opened and closed according to the progress of the construction of the building structure, and the actual Kaihei 4-1.
There is a roof that covers the entire building as disclosed in Japanese Patent No. 34351, in which the roof body is composed of a bag body in which a gas lighter than air such as helium gas is sealed, and the bag body is moored to the ground portion. In addition, it is proposed that the seat shelter be expanded and contracted to be temporarily installed.

[0003]

As described above, recently, the working environment has been improved to secure a labor force, and the number of working days has been secured by a planned working process regardless of the weather, thereby reducing the construction period. Various methods have been planned and implemented in the sense of strict adherence, but if the construction of the temporary roof is carried out by the large-scale erection method as in the above-mentioned conventional example, the erection cost will be enormous, and it will be less effective if it is not a certain scale There is no.

Further, the construction method and structure as a temporary roof is either temporary or versatile depending on the construction scale, structure and work purpose, or is selected by leasing or the like, but after all, temporary cost Considering the cost balance of the building itself, there is a problem that a uniform work environment cannot be obtained due to constraints such as small-scale construction and the structure of the building.

The present invention has been proposed in view of the above problems of the prior art, and its object is to provide a simple erection method according to a high-rise or middle-low rise building whose plane scale is not relatively large. Accordingly, it is possible to reduce the temporary installation cost and provide a simple temporary roof that can obtain the same working environment as the conventional device.

[0006]

In order to achieve the above-mentioned object, a simple temporary roof according to the present invention has a total of four steel frame columns facing each other in the girder direction and the span direction. As a unit, a hanger rail with a roof slope is installed between steel columns facing each other in the span direction, and an opening / closing membrane with an opening / closing mechanism is installed between the hanger rails facing each other in the girder direction. A fixed roof having a ridge member is disposed on the roof, and the roof portion is covered with the opening / closing membrane.

According to the second aspect of the present invention, the opening / closing mechanism includes a guide ring attached to a hanging bolt of a hanger roller rolling on the hanger rail, and a horizontal bridge installed between the columns supporting the hanger rail. Pulleys are provided on both sides of the frame, and the rope attached to the opening and closing membrane is inserted into the circular ring of the suspension bolt, and the rope is wound through the pulley. It is configured by being wound around a machine.

[0008]

According to the present invention, as described above, the portion erected in a total of four steel columns facing each other in the girder direction and the span direction constitutes one unit, and the roof slope is provided between the steel columns facing in the span direction. Since the hanger rail was installed with the above, and the opening and closing membrane with the opening and closing mechanism was arranged between the respective hanger rails facing each other in the girder direction, the opening and closing membrane was placed on the upper floor of the working floor and A fixed roof having a building material is disposed between the hanger rails that are arranged in the girder direction, and the temporary roof is covered by covering the roof surface between adjacent units with the fixed roof and the opening / closing membrane. Installed, the work on the lower floor of the temporary roof is not affected by the weather, and the opening / closing mechanism makes it possible to open the roof during fine weather and facilitate the loading of construction materials, greatly improving the working environment for workers. It is profitable.

In the opening / closing mechanism of the present invention, a cord having an end attached to the opening / closing membrane is inserted into a circular ring attached to a hanging bolt of a hanger roller rolling on the hanger rail,
By winding with a winder through the pulleys on both sides of the horizontal member that supports the hanger rail, the hanging bolt of the opening / closing membrane in the opening direction is moved along the hanger rail, The circular ring and the cord are fixed and wound in the opening direction via a winder, whereby the opening / closing membrane is contracted to open the temporary roof surface. When the temporary roof surface is closed, the opening / closing membrane is wound up by the winder in the opposite direction and stretched on the roof surface to form the temporary roof.
