DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building beam erection device for a building construction, which does not require attaching and detaching a reinforcing brace every time the beam structure is raised and lowered.

[0002]

2. Description of the Related Art A temporary beam assembly device has been proposed as a temporary scaffold for building a high-rise building. As shown in FIG. 2, the temporary beam assembling apparatus includes at least four temporary columns 2 arranged around a building 1 to be constructed, and a lifting / lowering device 3 located above the temporary columns 2 between the temporary columns 2. And a possible beam structure 4. The beam assembly structure 4 includes a bundle 5 arranged above and below the elevating device 3 so as to be able to move up and down, a pair of crane traveling beams 6 erected on the top of the bundle 5, and both ends of the crane traveling beam 6 at the top. An overhead crane 7 that can be guided and travel and a temporary roof 8 that can open and close the upper part of the crane travel beam 6 are provided.

This beam assembly apparatus raises a beam assembly structure 4 via an elevating device 3 in accordance with the degree of progress of construction of a building 1, and a column member constituting a part of a temporary column 2 unitized at a raised position. By repeating the work of adding the pieces into a worm-like shape, the building is sequentially raised, and after the construction is completed, by removing the support members while lowering the beam-structured structure 4, it is possible to finally remove the temporary support 2 together with the temporary support 2. The construction of objects can be automated and can be diverted to building buildings of similar size as many times as possible, and the roof can be installed on the crane traveling beam 6 so that construction can be performed without being affected by the weather, so that the construction period is stable. There are advantages.

[0004]

However, in order to prevent deflection of the beam structure 4 and secure self-standing stability, it is necessary to provide a reinforcing stay. For this purpose, as shown in the figure, a reinforcing brace 9 having both ends supported by a connecting beam 8 erected between the lifting devices 3 and having a vertex connected to the lower center of the crane traveling beam 6 is provided. I have.

However, in the case of this reinforcing structure, since the bundle column 5 is repeatedly moved up and down relative to the elevating device 3, it is necessary to attach and remove the brace 9 every time the elevating operation is performed. Because this is a work at height,
There is a problem that the worker is exposed to danger each time, and there is a concern that the rigidity is reduced at the time of removal.

An object of the present invention is to solve the above problems, and an object of the present invention is to provide an erection beam assembling apparatus for a building construction in which it is not necessary to attach and remove a reinforcing brace every time the beam erection structure is moved up and down. It is.

[0007]

In order to achieve the above object, the present invention is directed to a plurality of temporary supports arranged around a building to be constructed, and a temporary support provided on the top of each temporary support and sequentially moving the temporary supports upward. In the temporary beam assembly device, which is provided with an elevating device that holds the beam structure in the upper gripping device unit, the beam assembly structure is erected between the upper gripping device unit side of each of the elevating devices, or Both ends are supported by a crane traveling beam erected between the tops of the bundle pillars held by the gripping unit and a connecting beam erected between the lower gripping units of each lifting device, and the tops are connected to each other to form a triangle. An assembled reinforcing brace, an intermediate column having a lower end fixed to the connecting beam and an upper end connected to the vertex, slidably disposed at the upper end of the intermediate column, and a top coupled to the crane traveling beam. Telescopic member It is those with a.

[0008]

When the column is lowered relative to the elevating device, the telescopic member is immersed inside the intermediate column, and the truss structure including the brace and the intermediate column is maintained. Since the telescopic member extends upward together with the crane traveling beam when ascending, and the lower part of the telescopic member is still fitted inside the intermediate column, the truss structure is maintained in that state, the rigidity of the beam structure and the self-standing of the column Maintain sex.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail.
It is to be noted that the same reference numerals as those in the related art are given the same reference numerals as those in the related art, and only changed or newly added parts will be described using different reference numerals. 1A to 1C show a roof structure 4 having a reinforcing structure according to the present invention.

In the figure, the tops of a pair of reinforcing braces 10 whose both ends are supported by a connecting beam 8 erected between a lower gripping unit 3b of a lifting device 3 are connected to both sides of a connecting fitting 12 in a triangular shape. ing. The lower end of the intermediate column 14 is fixed to the center of the connecting beam 8.
The upper end of 4 is connected to the center of the connection fitting 12 and halves the triangular shape formed by the reinforcing braces 10.

As shown in an enlarged view of a part of FIG. 1A, a telescopic member 16 is slidably fitted on the outer periphery of the upper part of the intermediate pillar 14, and the upper part of the telescopic member 16 is connected to the connecting fitting. 12 is fixed to the center of the lower end of the crane traveling beam 5 by bolts or the like while penetrating both sides of the crane traveling beam 12.

In the above configuration, the bundle pillar 5 of the roof structure 4
As shown in FIG. 1 (a), in a state where the telescopic member 16 is held at a relatively low position with respect to the elevating device 3, the telescopic member 16 is lowered and connected to the upper outer periphery of the intermediate column 14, and The top of the metal fitting 12 is in contact with the lower surface of the crane traveling beam 6 and holds the reinforcing structure by the truss assembly.

From this state, as shown in FIG.
Is pushed up to the upper position of the elevating device 3, only the elastic member 16 rises, and the reinforcing brace 10 and the intermediate column 14 are raised.
The truss braided structure is maintained in that state. In this state, the work of connecting the support member to the top of the temporary support 2 and extending the temporary support 2 upward is performed.

After completion of the connecting operation, as shown in FIG. 1 (c), when the lifting / lowering device 3 itself is raised, the truss assembly structure itself is also raised. The apex of twelve will be abutted against the lower end of the crane traveling beam 6 as before.

In this embodiment, the crane traveling beam 6
Column 5 held by the upper gripping device 3a of the lifting device 3
Although it is installed between the tops, it may be installed between the upper gripping device 3a side.

[0016]

As described in detail in the above embodiments, in the temporary beam assembly apparatus for building construction according to the present invention, at the lowering position of the column relative to the elevating device, the telescopic member is located inside the intermediate column. The truss structure is retained by the truss structure with the brace and the intermediate column, and the telescopic member extends upward together with the crane traveling beam when ascending, and the lower part of the telescopic member remains fitted inside the intermediate column. In this state, the rigidity of the beam structure and the independence of the columns are maintained, so there is no need to manually attach and remove the brace every time the roof structure moves up and down as in the past, eliminating the danger of working at heights. , Labor can be saved. Also,
There is no concern that the rigidity of the entire structure will decrease with each removal.
