Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a method of constructing a high-rise building, and in particular, to constructing core parts at both ends of the building in advance, and constructing internal components sandwiched between the core parts. This invention relates to an improvement in the method of constructing a core by supporting it.

(Prior Art) Japanese Patent Publication No. 54-11965 discloses the following method of constructing a high-rise building.

Two core sections, which will become the structures at both the left and right ends of the building to be constructed, are constructed vertically to a predetermined height at a predetermined interval at a planned construction site. Once both cores have been constructed to a predetermined height, an upper suspension structure that can be regarded as a rigid body is constructed on top of them.

On the other hand, the precast ceiling slab, floor slab, and pitching are carried between the core section, and the ceiling slab is first lifted up by one layer, the precast wall panels are attached to it, and then the lower part of the pitching is lifted up. Assemble the floor slabs and assemble one-story residential unit blocks as ground work.

Then, the assembled housing unit block is lifted by a lift jack set on a lift-up rod suspended from the above-mentioned upper suspension structure, which is a bridge between the topmost parts of the core section. The ceiling slab and floor slab of the housing unit block lifted to a predetermined height are rigidly connected to the core part, and at the same time, the upper housing unit block is also rigidly connected to assemble the lifted housing unit block as a part of the building.

In this way, the building between the core parts is constructed by sequentially moving housing unit blowers between the two core parts from the upper floor to the lower floor.

(Problem to be Solved by the Invention) In the conventional method described above, assembly of the building between the core parts cannot be started until after the two core parts have been constructed to their final height. Therefore, especially when constructing high-rise buildings using this method, there is a drawback that the construction period is prolonged if the building between the core sections is assembled after the core sections are completed.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to sequentially construct two core sections upward, and to assemble a building between the core sections that have been partially constructed. The objective is to provide a method of constructing a high-rise building that allows the construction of high-rise buildings to be carried out in parallel.

(Means for Solving the Problems) Therefore, in the construction method of the present invention, in parallel with the work of sequentially constructing two core parts facing upward over a sufficiently large length in the horizontal direction, both core parts are The frame of the building to be constructed during this period is assembled on the ground side as a large number of frame blocks divided into layers each having a size obtained by dividing the length L into several parts.

Then, the body block is transported in a horizontal direction to a predetermined position in the space facing both the core parts, and the body block is lifted to a predetermined height by a lifting means provided along the facing surfaces of the core parts. The frame block is moved in the horizontal direction by a lateral moving means provided along the opposing surfaces of both core parts, and both ends of the frame block are joined and fixed to both core parts in a predetermined direction.

Moreover, an interval of at least one floor is provided between the ceiling surface of the lower framework block and the floor surface of the upper framework block.

(Function) In a portion of the opposing space between the two core parts excluding the space occupied by the lifting means, there is a space between the two core parts so that the pivot blocks assembled on the ground side are stacked one after another from bottom to top. Can be assembled.

Therefore, even if both core parts are not completed to their final height, the frame blocks can be sequentially assembled between the partially constructed core parts. Moreover, the space between the building blocks becomes a hall without pillars.

(Example) Fig. 1 shows the construction of a high-rise building to which the present invention is applied, and Fig. 2 shows the construction procedure in the embodiment of Fig. 1. In both figures, 1 and 2 are core parts, and the core parts 1 and 2 are constructed so as to face each other in parallel with a distance M maintained over a sufficiently large length L in the horizontal direction.

As shown in FIG. 1, there are four cranes 3, 4, 5, 6 to construct the two core parts 1 and 2, and these cranes lift up the frame member W of the core part ,
The core portion 2 is constructed sequentially upward. In the state shown in FIG. 1, portions 7 to 8 of core portion 1 and core portion 2 are almost completed, and construction of the upper floors is proceeding.

On the ground of this construction site, a pair of rails 7 are laid from the part sandwiched by core part 1 and core part 2 to the sides, and the square on the side of core part 1 and core part 2 is the building block. 8 production line Z.

The frame block 8 is a structure in which the frame of a building to be constructed between the core part 1 and the core part 2 is divided into layers with a size obtained by dividing the length into 173 parts. This frame block 8 is manufactured in a progressive manner on a rail 7 in a plaza serving as a manufacturing line Z.

In other words, there are 8 building blocks around the plaza that will be production line 2.
Material Y was brought in and crane 9, 10.11.1
2, etc., to fabricate the frame block 8 on the rail 7. First, the frame of the frame block 8 is assembled, and then reinforcing bars and formwork are installed and concrete is poured, or precast concrete is assembled to obtain the frame block 8 with an integrated floor and beam structure.

The frame block 8 is sequentially sent to the core portion 1 and the core portion 2 side as its manufacturing progresses. The manufactured frame block 8 is then moved horizontally along the rails 7 and carried to the lifting space S in the center of the space where the core parts 1 and 2 face each other.

In the underground part of the lifting space S between the core part 1 and the core part 2, a lifting frame 13 shown in the third factor is set. On this lifting frame 13, there is a rail 7a which is continuous with the rail 7 when it is at the lowest position, and the frame block 8 transported on the rail 7 is placed on the lifting frame 13. ing.

In addition, in order to move the lifting platform 13 up and down along the opposing surfaces of the core section 1 and the core section 2, a rack device 14 is attached to each opposing surface of the core section 1 and the core section 2. At the bottom of the pedestal 13, there is a binion device 1 that engages with the rack device 14 and drives the pedestal 13 in the vertical direction.
5 is installed.

As described above, the frame block 8 is carried into the lifting space S and placed on the lift frame 13, and the pinion device 15 is operated to raise the frame block 8 along the rack device 14 to a predetermined height. Next, the frame block 8 on the pedestal 13
horizontally to the right or left, position a new frame block 8 above the lower frame block 8 that is already fixed between the core parts 1 and 2, and then move the frame block 8 horizontally to the right or left side.
Both ends of the hook 8 are joined and fixed to opposing surfaces of the core portions 1 and 2.

Although it is not clearly shown in the figure, the means for moving the frame block 8 on the pedestal 13 in the lateral direction along the facing surfaces of the core parts 1 and 2 at a predetermined height position is not clearly shown in the figure, but the core part 1 A guide rail is provided in the horizontal direction on the opposing surface of the core portion 2, and the frame block 8 is moved along this.

As described above, the building blocks 8 are manufactured one after another in the square that is the building block production line Z, and the completed building blocks 8 are carried along the rails 7 to the bottom of the lifting space S, and then the building blocks 8 are The frame block 8 is placed on the frame 13 and raised to a predetermined height, and then the frame block 8 is horizontally moved to the right or left from the frame 13 to position it, and in this state, the frame block 8 is coupled to the core part 1 and the core part 2. and fix it.

In addition, as shown in FIG. 1, when the building blocks 8 are sequentially added from the lower floors to the upper floors, there is at least a gap between the ceiling surface of the lower building blocks 8 and the floor surface of the upper building blocks 8. Leave an interval K of one floor. Then, the space between them becomes a hall without pillars.

(Effects of the Invention) As described above in detail, according to the present invention, while the two core parts are constructed in sequence upward, the building block is placed between the two core parts for the lower floor part that has already been constructed. can be sequentially assembled from bottom to top and fixed to both core parts. Therefore, the construction of the core section upwards and the building frame between the core sections can proceed in parallel upwardly, significantly shortening the construction period compared to conventional methods. .

Additionally, since there is a gap of at least one story between the ceiling of the lower frame block and the floor of the upper frame block, the space in the gap can be used as a hall without pillars. .
