Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to building a building by a push-up method using a jack device.
It relates to a construction method that always ensures the accuracy of the plane position of the driving floor and the erection accuracy of the columns.

[0002]

2. Description of the Related Art A push-up construction method using a jack device is a construction method in which an uppermost floor including a roof is first constructed as a driving floor in the early stage, and this is sequentially pushed up by a jack device to construct a building. Provide a safe and comfortable workplace environment with a mold. The driving floor is a standard for the construction accuracy at each stage of the push-up construction method.
However, conventionally, the plane position of the driving floor is merely measured by swinging down to ensure accuracy. Also, the erection accuracy of the pillars that support the drive floor is measured by measuring the verticality one by one,
If there is an error, it is corrected by such means as pulling the wire hung on the pillar using a hand or a special jack.

[0003]

However, a high accuracy cannot be obtained by the method of individually correcting the accuracy of the plane position of the driving floor and the erection accuracy of the pillars as required like the conventional construction method. Not only that, it takes time and effort individually, which hinders the advantages of the push-up method and also has a problem in safety.

Therefore, an object of the present invention is to provide a building construction method which always and efficiently corrects the plane position accuracy of the driving floor and the erection accuracy of columns in the push-up construction method.

[Means for Solving the Problems] As a means for solving the above problems, in the construction method of a building by the push-up method according to the first invention, upper and lower pin portions are provided between the drive floor 1 and the pillar 2. A jack device 5 for alternately reacting 10a and 11a to the pillar 2 to raise and lower the driving floor 1 is installed, and the plane position of the driving floor 1 is measured by a plane position measuring device 3, and this measurement is performed. Based on the result, the correction means attached to the jack device 5, for example, the upper pin portion 10a applies a reaction force to each of the columns 2 to correct the plane position of the driving floor 1 to constantly adjust the plane position of the driving floor 1. Maintaining accuracy, with reference to the driving floor 1 whose accuracy of horizontal position is maintained,
Multiple columns other than the specific column to be corrected 2
To the correction means, that is, the upper pin portion 10a.
Alternatively, the erection accuracy of the pillars 2 is individually corrected by driving the upper guide rollers 9, respectively.

Next, the second aspect of the present invention has most of the configuration in common with the first aspect of the present invention, but in addition to that, a plurality of elements for moving the output shaft 13a forward and backward in the XY two-dimensional direction of the plane with respect to the pillar 2 are provided. Correction means, for example, the correction jack 13 is installed in the lifting jack device 5, and the correction jack 13 applies a reaction force to each of the columns 2 to correct the plane position of the driving floor 1 and tries to correct the same. A reaction force is applied to a plurality of pillars 2 other than the pillars, and the correction jack 13 increases the erection accuracy of the pillar 2 to 1
It is characterized in that correction is added individually for each book.

In the above-mentioned plane position measuring device, the laser beam vertical projector 3 is installed on the ground, and the laser beam emitted from the laser beam vertical projector 3 is projected onto the target 4 on the driving floor 1. Then, the plane position of the driving floor 1 is measured.

[0008]

The laser beam emitted from the vertical projector 3 of the laser beam is projected onto the target 4 to measure the plane position of the driving floor 1, and the error (deviation) of the plane position is detected. The reaction force is applied to all the columns 2 supporting the driving floor 1, and the driving floor 1 is moved in the horizontal direction by the upper guide roller 9 and the upper lock pin device 10 which are correction means to correct the plane position and accuracy. Give out. After that, the erection accuracy of the pillar 2 is taken as a reaction force to all the pillars 2 other than the specific one pillar to be corrected, and the upper guide roller 9 and the upper lock pin device, which are also correction means, are used. The erection accuracy of the pillar 2 is corrected by 10 and the accuracy is individually obtained.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an elevation view showing an intermediate stage of building a building by the push-up method. At the beginning of construction, the top floor is constructed on the drive floor 1, and the pillar 2 is constructed in advance by a crane or the like (not shown), and the drive floor 1 is raised by the jack device along the pillar 2, and after that. Construction of the lower floors and exteriors will be carried out. For example, after securing the erection accuracy of the pillar 2, the beam 15 on the lower floor is attached. On the other hand, one or a plurality of laser beam vertical projectors 3 are installed upward on the ground, and a vertical laser beam emitted from the laser beam vertical projectors 3 is projected onto a target 4 set on the lower surface of the driving floor 1. The plane position of the driving floor 1 is constantly measured, and the error (deviation) in the plane position of the driving floor 1 is detected.

Between the driving floor 1 and the pillar 2, a jack device 5 is installed which pushes up the driving floor 1 by applying a reaction force to the pillar 2. As a specific configuration of the jack device 5, as shown in FIGS. 2A and 2B, the racks 6 and 7 in which steel materials are combined in a cross-shaped manner around the column 2 are provided at the top and bottom, and four jacks 8 are used as the columns. It is arranged in parallel to the column 2 and symmetrically around the column 2 around the column 2. On the mounts 6 and 7, a pair of two guide rollers 9 tilted in a direction of 45 ° so as to come into contact with the sides of the column 2 at right angles to two sides are diagonally connected to the column 2 by a driving unit 9 ′ such as a jack. It is installed so that it can move back and forth in any direction. On the same pedestal 6 and 7, lock pin devices 10 for moving the lock pins 10a and 11a, which exert a reaction force to the reaction force receiving portion 2a of the column 2, inward and backward in a diagonal direction different from the arrangement of the guide rollers 9 by 90 °. , 11 are installed. Therefore, in the jack device 5, the lock pin devices 10 and 11 and the guide roller 9 are arranged on the pillar 2 in a flat X direction.
The output shaft can be moved back and forth in the -Y two-dimensional direction. Therefore, when the jack device 5 is arranged on the driving floor 1 as described above, the lock pin devices 10 and 11 and the guide roller 9 can be driven in the X-Y directions of the plane of the building shown in FIG. it can. The original function of the jack device 5 is that the upper and lower lock pin devices 10 and 11 alternately apply a reaction force to the reaction force receiving portion 2a of the column 2 to extend and retract the jack 8 to push up the drive floor 1.

Can be moved in any direction (Fig. 4A, B). Similarly, when one of the upper lock pin device 10 or the guide roller 9 located in the X direction is extended and the other is contracted, the drive floor 1 can move diagonally upper right or diagonally lower left (FIG. 4C,
D). Furthermore, by performing various combinations of the operations shown in FIGS. 4A to 4D, the plane position of the driving floor 1 is 360 °.
It is possible to correct in any direction of all directions.

After the accuracy of the plane position of the drive floor 1 is secured as described above, the erection accuracy of each pillar 2 is obtained with reference to the position of the drive floor 1. To that end, a reaction force is applied to all (or a large number, the same applies hereinafter) of all the columns 2 other than the specific one column for which the erection accuracy is to be corrected, and the upper lock pin device 10 in the XY direction of the columns is used. Also, the upper guide roller 9 is moved back and forth, and the same pillar 2 is moved in the XY directions to make a correction to obtain the erection accuracy. For the other pillars 2, the erection accuracy of the pillars 2 is obtained in conjunction with the accuracy of the plane position of the driving floor 1 by sequentially correcting the erection accuracy described above, and the building construction is accurate and efficient.
