Abstract

PURPOSE:To enable working in a rainy weather condition by forming a hood including a building and outer peripheral scaffolds, with the use of high story framework scaffolds and low story framework scaffolds, and to enable the hood to be opened in part or in its entirety in a fine weather condition or upon introduction of construction materials. CONSTITUTION:Columnar parts of L-like shape beams (a, b, c, d) are inserted into bearing parts 3, 4, 5, 6 provided in the topmost parts of vertical pipes of a construction frames 1, 2 of framework scaffolds attached to a longitudinal wall surface of a building, and of temporary scaffolds, and joint parts of beams which are opposed to one another are connected and fixed together by means of plate cams 10, 11, 12, etc., so as to form a framework, and then an awning is attached to the framework so as to form a hood. The L-like shape beams are connected together by parallel links 8, 9, and stepped parts are formed to the beams, and accordingly, the beams (a, c) can be turned aside the beams (b, d) adjacent thereto. The beams (a, c) are turned by an angle of about 90deg., and are stopped at positions where they are in parallel with the longitudinal direction of the building. Then, the beams (b, d) having low stepped parts are turned toward the beams (a, c) having high stepped parts by an angle of about 90deg. so as to open the hood, thereby it is possible to introduce construction materials.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction scaffold for facilitating work in a construction site in case of rain.

[0002]

2. Description of the Related Art Conventionally, in construction sites, frame scaffolds have been used for high-rise buildings and temporary scaffolds have been used for low-rise buildings. In both cases, no measures were taken in case of rain, which hinders work in rain.

[0003]

[Problems to be Solved by the Invention] In rainy weather, it is difficult to carry in construction equipment and perform peripheral works such as caulking painting, resulting in a delay in the construction period and an increase in the construction man-hour, resulting in an extremely large economic loss. there were.

According to the present invention, the skeleton of the canopy is constructed by the beams attached to the upper part of the frame scaffolding / temporary scaffolding at the beginning of the construction work, and by attaching the awning, the whole building is fit under the awning.
The purpose is to easily store the awning together with the skeleton of the canopy as needed.

[0005]

[Means for Solving the Problems] A bearing portion, which serves as a rotation center of a beam serving as a frame of a canopy, is provided above a building frame of a frame scaffold and a vertical pipe of a temporary scaffold.

When a plurality of beams turn, a step is provided so as not to interfere with the adjacent beams.

By providing beam swivel bearings on both sides of the building, the corresponding beams can be connected and fixed at the center of the building to form a canopy frame.

By connecting a plurality of beams with parallel links, a plurality of beams can be turned in the same phase by a link operation at one place.

The total length of the beam can be easily adjusted according to the width of the building.

In order to be able to use a standard awning, a retaining pin is attached to the upper part of the beam in accordance with the eyelet spacing of the awning, and the awning is shaped so as not to generate a pulling force in the turning direction of the beam group.

[0011]

According to the present invention, the pillars of each beam group and the central joint of the beams are fixed to form a frame of a canopy as beams fixed at both ends, and the awning is attached to form the entire roof. The canopy is stowed by connecting the fixed parts of each beam group and releasing the reinforcement of the high-rise beam support, and pivoting each beam group by a link operation.
