Field of the Invention The present invention relates to an assembly work for constructing a structure such as steel reinforced concrete, reinforced concrete or steel structure, especially a general rectangular housing, a school or an office building having a flat rectangular shape on the middle floor or the lower floors. Concerning the construction method for saving labor.

[0002]

2. Description of the Related Art Conventionally, in the work of constructing the above-mentioned structure, the material is carried in from the material loading opening or the outside of the structure by a crane of a mobile crane or a tower crane.
The building materials are temporarily placed on a work gantry or a slab, and many workers carry or arrange the materials that have been appropriately carried in to arrange or assemble them.

[0003]

However, in the above-mentioned construction method, a lot of manpower is required, and the mechanization and robotization of the work are delayed, which is far from labor saving and a great burden is imposed on the worker. There was a shortage, and there was a problem that it also hindered securing the deadline for the construction period. Further, in the transportation of the materials, various materials placed on the slab or the slab reinforcement are obstructed and the efficiency of the transportation work is poor. Since work is often interrupted when the wind and rain are strong, a protective sheet may be used to cover the entire structure to avoid this, but this also requires that the protective sheet be replaced as the building is assembled. There was a drawback that it was very time-consuming.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for constructing a structure in which the construction work in the planar rectangular structure is automated and the work efficiency is improved. And

[0005]

The gist of the present invention to solve the above problems and achieve the above objects is to construct a foundation on the ground where a structure is to be constructed, and then, in the longitudinal direction of the plane outer peripheral portion of the foundation. A girder unit formed by vertically arranging a steel column for guides to form a girder-shaped girder and mounting a traveling device movable in two directions on a guide rail provided under the girder is described above. The girder is slidably fitted in the steel column in the vertical direction, and a jack is attached to the upper part of the girder column where the girder unit is fitted, and an overhead crane or an assembly robot is attached to the traveling device attached to the girder. The building equipment is carried in and building members are assembled by moving the traveling device to the adjacent girder unit via the guide rails of the above as required, and the building members are attached to the steel columns after the assembly of a predetermined hierarchy is completed. A large beam unit consists in carrying out the loading and assembly of building materials of the lift up to the top hierarchy in the Yakki.

Further, a temporary roof is provided above the girder unit so as to be slidable in the vertical direction with respect to the steel column and movable in the longitudinal direction of the structure so that a part of the temporary roof is opened. That is what I did. Further, it is preferable that the guide steel frame column is also used as a core rebar for a column of a structure to be constructed.

[0007]

According to the method of constructing a structure according to the present invention, in constructing a horizontally long structure having a rectangular plane shape, a traveling device provided in a girder unit can carry in building materials with an overhead crane, and The assembly robot mounted on the traveling device can assemble members and place concrete to automate construction work. Then, if the heights of the guide rails of the adjacent girder units are adjusted, the traveling device can be laterally moved over the plurality of girder units via the guide rails, so that it is possible to carry out the material transportation and the assembly work. Efficiency improves.

Further, according to the second aspect, the temporary roof can easily withstand the rain, and the construction work can be performed regardless of the weather. Further, since a part of the temporary roof can be moved in the lateral direction, a part of the temporary roof can be opened, and the building materials can be carried in from here.

Further, according to the third aspect, there is no need to refill the steel column for guide.
