[0023]
(First step)
In the first step, the hat truss 8 and the fixed frame 2 are constructed.
After the hat truss 8 similarly laid in advance is erected on the upper part of the fixed frame main body 3 laid in advance to form a unit, the unit is pushed up by using a push-up means (not shown) such as a jack, and as shown in FIG. As shown, a new fixed frame body 3 is inserted from below and laminated.

To the outer peripheral surface of the fixed frame 2.
By repeating such a process, a predetermined number of variable frame bodies 12 are temporarily supported at a predetermined height position of the fixed frame 2 as shown in FIG.
[0026]
(Third step)
In the third step, after the variable frame main body 12 located below is supported by the variable frame main body 12 located immediately above, the temporary hanging members 17 are removed.
As shown in FIG. 5 (b), the other end 13b of the variable beam 13 forming the variable frame main body 12 is connected to the other end of the hanging member 16 hanging directly above, thereby forming the hanging member. The step of supporting the variable frame main body 12 at 16 and then removing the temporary hanging members 17 are repeated in order from each variable frame main body 12 located above and downward. Thus, the variable frame 11 supported by the hat truss 8 is formed, and the variable-height stacked structure 1 is constructed.
[0027]
As shown in FIGS. 6A and 6B, such a variable-height stacked structure 1 has a configuration including the above-described hat truss 8, the fixed frame 2, and the variable frame 11 as one basic unit 19. These may be connected in the horizontal direction.
[0028]
Further, the variable-height stacked structure 1 can be easily changed even when it is desired to change the floor height of a certain level after the variable-height stacked structure 1 is constructed. . Hereinafter, with reference to FIGS. 7 and 8, a method of changing the floor height of a predetermined level in the variable-height stacked structure 1 after the construction will be described in detail.
[0029]
(First step)
Temporarily support the variable frame main body 12a that forms the floor whose floor height is to be changed. As shown in FIG. 7A, the other end 13b of the variable beam 13 and the fixed frame 2 are connected to the variable frame main body 12a and the variable frame main body 12b directly below the variable frame main body 12a forming the story whose floor height is to be changed.

[0030]
(Second step)
The variable frame main body 12a forming the hierarchy whose floor height is to be changed is moved in the height direction.
As shown in FIG. 7B, after removing the fastening means 18 for pin-joining one end 13a of the variable beam 13 constituting the variable frame main body 12a and the fixed frame 2, the lifting means 7 is removed. , The variable frame main body 12a is lifted along the fixed frame 2 and moved to a desired height position.
Thereafter, as shown in FIG. 8 (a), one end 13a of the variable beam 13 constituting the variable frame main body 12a and the outer peripheral surface of the fixed frame 2 are again fastened via the fastening means 18, and From the lower chord material 8b of the hat truss 8 to the variable frame main body 12a of which floor height has been changed and the variable frame main body 12c immediately above, via the lifting means 7 vertically provided along the outer peripheral surface of the variable frame 11. The exterior curtain wall 10 is installed, and the hanging member 16 is installed.
Finally, as shown in FIG. 8B, the temporary suspension members 17 connected to the variable beams 13 of the variable frame main body 12a whose floor height is changed and the variable frame main body 12b immediately below are removed, and the variable frame 11 Lifting means 7 suspended along the outer peripheral surface is also removed.
Thereby, the variable-floor-type laminated structure 1 can easily change the floor height of the hierarchy even after the construction.
[0031]
In the present embodiment, the entire variable frame main body 12 forming the hierarchy to be changed is moved in the height direction, but this is not necessarily the case.
For example, as shown in FIG. 2, a plurality of unit flat plates 15 each including an area surrounded by the variable beam 13 and the orthogonal beam 14, and the adjacent unit flat plates 15 are connected to the variable frame main body 12 via connecting beams 15 a. With a configuration including a configuration in which the variable frame body 12 is removed at a desired position, the height of the variable frame main body 12 can be partially moved as shown in FIG. 9.
[0032]
According to the above-described configuration, the variable-height laminated structure 1 has a configuration in which the variable frame 11 is suspended and supported by the hat truss 8 and the hat truss 8 is supported by the fixed frame 2. Since the load of the entire variable-height laminated structure 1 is supported by the fixed frame 2, the variable frame 11 is connected to the fixed frame on the inner peripheral edge by pin connection via the fastening means 18. And a simple configuration that can be easily constructed and disassembled. Moreover, since the dismantling can be performed without damaging the structural members, the structural members after dismantling can be reused.
[0033]
Since the variable frame 11 is suspended and supported by the hat truss 8 and the weight of the floor material 9 provided on the variable frame 11 is reduced, when the earthquake occurs, the variable frame 11 Response can be reduced and seismic performance can be improved.
[0034]
The variable-height laminated structure 1 has a configuration including the variable frame 11, the hat truss 8, and the fixed frame 2 as one basic unit 19, and these are connected in the horizontal direction. It is possible to construct the variable-height laminated structure 1 having a simple configuration.
[0035]
Since a plurality of communication spaces 6a and 6b are formed inside the fixed frame 2, the communication spaces 6a and 6b are provided with equipment pipes and lifting / lowering equipment, so that they can be easily connected to all floors. And the level of the variable frame 11 can be changed without affecting these equipment piping and the elevating equipment.
[0036]
According to the method of constructing the variable-floor stacked structure 1, the hat truss 8 is provided with the lifting means 7, and the lifting means 7 is used to lift the variable frame body 12 forming a story. Since the movable frame main body 12 is laid on the outer periphery of the fixed frame 2 because the movable frame body 12 can be moved only in the vertical direction by the lifting means 7, the floor material 9 and the exterior curtain wall 10 can be laid at the time of laid. With this configuration, the workability can be greatly improved, and it is possible to greatly contribute to shortening the construction period and reducing the construction cost. Also, when dismantling or changing the floor height, it is not necessary to use a new lifting machine, which can greatly contribute to the reduction of construction costs.
