DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a temporary roof structure for covering an upper part of a beam structure in an all-weather temporary beam system for building construction.

[0002]

2. Description of the Related Art As a temporary scaffold for building high-rise buildings, an all-weather temporary beam assembly apparatus has been proposed. This temporary beam assembly device has at least four beams arranged around the building to be constructed.
It includes a temporary support of the book and at least one pair of temporary beam assembly structures that are laid parallel to the upper part between the temporary supports and that can be raised and lowered via a lifting device.

[0003] The temporary beam structure is provided with a construction facility for building a building such as a crane and is used for hanging a temporary roof over the building. The beam structure is raised in accordance with the progress of building construction. After the construction is completed, it is lowered and finally removed together with the temporary pillars. It can be converted to a building of similar size as many times as possible, and the roof allows the construction to be performed regardless of the weather. ,
There are advantages such as a stable construction period.

[0004]

However, in this structure, the temporary roof is obstructed before finally lowering the erection beam structure, so that the erection roof must be dismantled and removed first. Did not. This work was dangerous because it was performed at high places, and the dismantled roofing materials had to be removed from high places, which took time to carry out and required reassembly of the roof during diversion.

The present invention has been made to solve the above problems, and an object of the present invention is to fold and unfold it on an upper part of a beam structure, and to disassemble and remove one side or a lower part when a temporary beam structure descends. An object of the present invention is to provide a roof structure of a temporary girder assembly for building construction capable of avoiding interference with a building constructed on both sides.

[0006]

In order to achieve the above-mentioned object, the present invention is directed to a construction in which at least four temporary struts arranged around a building to be constructed are extended in parallel with an upper portion between the respective temporary struts, in the provisional設梁set apparatus for building construction that includes at least a pair of temporary beam sets structure elevatable via the lifting device, a number of which is movably supported at both ends perpendicular the top of each temporary beam pair structure Each of the temporary beam structures , comprising: a power bone; and a flexible sheet stretched over each power bone to form a hood roof that can be deployed and folded at an upper portion between the beam structures.
And the folded hood roof are outside the building in plan view.
It is characterized by the following.

[0007]

The seat is deployed by arranging the power bones at predetermined intervals along the upper part of the beam structure, and covers the upper part of the beam structure in a hood roof shape. By moving each force bone to one or both sides of the upper part of the beam structure, the sheet is folded in a bellows shape, the upper part of the beam structure is opened, and the beam structure can be lowered without interfering with the building .

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. In FIGS. 1 and 2, a temporary beam assembly device 1 includes four temporary columns 3 arranged on the outer periphery of a high-rise building 2 to be constructed.
And a pair of large beams 5 installed in parallel on the upper part of each lifting device 4.

The lifting / lowering device 4 includes a pinion that meshes with a rack included in a guide mechanism provided on each temporary support 3, and a motor for driving the rotation of the pinion. The girder 5 is moved up and down.

The girder 5 has a truss structure and is provided with a roof structure 7 which also serves as a crane girder of an overhead crane 6 whose both ends are supported at an upper portion at right angles to the truss assembly and which covers the entire upper portion.

The overhead crane 6 has a first traversing device 6a movable in the X direction along the beam 5 and a first traversing device 6a.
And a second traversing device 6b that moves in the Y direction along the road, and transports various building materials suspended on crane hooks 6c drawn out from the second traversing device 6b to an arbitrary location.

The roof structure 7 is composed of a large number of arch-shaped power bones 8, both ends of which are erected on the upper portions of both girders 5, and a flexible sheet 9 stretched over each power bone 8.

At both ends of each power bone 8, wheels 8 that can travel along guide rails 5a laid on the upper part of the girders 5 are provided.
a is provided so as to be movable on the girder 5. FIG.
As shown in FIG.
In the state of being placed on the upper side, the sheet 9 has a roof shape and is developed with a predetermined tension, and covers the opening between the girders 5 and the entire upper surface of the building 2 under construction.

The sheet 9 is made of a fibrous material or a vinyl sheet, etc., which is robust and lightweight, and can receive light. When the sheet 9 is entirely covered, it enables construction work without being affected by the weather. Lighting provides a good working environment.

After the completion of the building work, as shown in FIG. 3B, the force bone 8 is drawn to one end of the girder 5 so that the seat 9 is folded in a bellows shape.
Open the top between. Further, by retracting the overhead crane 6 to the other end of the girder 5, the girder 5 can be lowered to the ground via the elevating device 3 without interfering with the finished building 1.

After being pulled down to the ground, the power bone 8 and the sheet 9 are removed from the girder 5, and the dismantling operation of the roof structure 7 is completed. If they are bundled and stored in a folded state, they can be reused by simply placing the oscillating bone 8 on the rail 5a of the girder 5 at the ground portion when diverting.

In order to deploy and pull each of the power bones 8, a folding drive mechanism composed of, for example, a wire and a winch can be used, and no manual operation is required. The roof can be arbitrarily opened and closed as needed. In addition, in the embodiment, the power bone 8 is drawn only to one side. However, when the area of the building to be constructed is large, the group of the sheet 9 and the power bone 8 is divided into two parts, and when deployed, they are overlapped at the center. At the time of folding, it can be drawn to both sides of the girder 5.

[0018]

As described in detail in the above embodiments, in the roof structure of the temporary beam building apparatus for building construction according to the present invention, each force bone is arranged at a predetermined interval along the upper part of the beam structure. Then, the sheet is unfolded, the upper part of the beam structure is covered like a roof, and each force bone is moved to one side or both sides of the beam structure, so that the sheet is folded in a bellows shape and the beam structure is Since the upper part is open and the beam structure can be lowered without interfering with the building, the dismantling and removal work of the roof is not required, especially at the time of descent, so that safety can be improved and work efficiency can be improved. In addition, there is an advantage that dismantling and removal can be performed by separating the beam from the beam structure on the ground, and subsequent conversion can be easily performed.
