Abstract

PURPOSE:To make temporary columns unnecessary and to simplify equipments, by a method wherein permanent columns divided into two groups, which columns are provided in a roof structure for the top floor, are alternately used as the bases of reaction and the roof structure is lifted up. CONSTITUTION:Permanent columns A, B divided into two groups are provided in a roof structure 2 for the top floor. All of columns (a) for a building, corresponding to the permanent columns A in one of the groups, are installed. At this stage, the permanent columns A each are jacked-down and are allowed to be in contact with the columns (a). After that, cross beams 4 each are attached between the columns (a) and columns (b) by a structure-conveying and installing means. After that, while all loads of the roof structure 2 are being shifted from the columns (b) corresponding to the permanent columns B to the columns (a) corresponding to the permanent columns A, the roof structure 2 is jacked up by the height of one floor. After that, the columns (b) is carried in and is added to the column (b) installed by the structure-conveying and installing means. Operation above-mentioned is repeatedly performed and a building with necessary floors is constructed.

2. Description of the Related Art Conventionally, the roof structure on the top floor has been constructed in advance, enabling construction work that is not affected by wind and rain, and when the construction work for one layer is completed, the roof structure on the top floor is lifted up, one after another. As a construction method for carrying out, a frame frame provided with a horizontal conveyance means for horizontally conveying members and a roof of a building is provided, and a vertical conveyance means is provided with this roof as a suspension support point, and columns, beams, floor slabs, etc. To construct a building unit by stacking and constructing a core portion, taking a reaction force from the core portion to raise the frame frame, and transporting the building unit by the vertical transport means and the horizontal transport means There is a building construction method for building. (See, for example, Japanese Patent Laid-Open No. 4-111830)

[0003]

In the above-mentioned conventional technique, the frame frame is lifted by the lift-up mechanism while taking a reaction force from the core portion of the building. However, a temporary column for supporting the frame frame is required. . In addition, at the end of the construction work, that is, at the end of the work up to the top floor, it is necessary to dismantle and lower the temporary columns.

An object of the present invention is to eliminate the need for temporary columns and to simplify the equipment by lifting up the roof structure by alternately using two groups of main columns installed in the roof structure of the maximum limit as a reaction force. To provide a construction method.

[0005]

The structure of the present invention, which solves the problems of the prior art, has a roof structure on the uppermost floor that can be lifted up, and a jack or the like is lifted or lowered at a portion corresponding to a pillar of a predesigned building. A step in which main columns A and B which can be moved up and down by means and which are distributed to two groups in good supporting balance are provided, and all the columns a of the building corresponding to the main columns A of the one group are attached. Then, the main pillar A is jacked down to bring it into contact with the pillar a, and a transverse beam or the like is attached between the pillars a and b by means of the skeleton transport mounting means, and then the total load of the roof structure is applied to the main pillar B. After shifting the corresponding pillar b to the pillar a corresponding to the permanent pillar A, the roof structure is jacked up by a height corresponding to one floor, and then the pillar b is carried in by the skeleton conveying means to replenish it. Repeat for any hierarchy Constructing a Tsukibutsu, and the present 設柱 A, both posts a corresponding to B, and in which the height difference between the b is the height of one floor minute.
