Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a building construction method.

[0002]

2. Description of the Related Art A conventional building construction method employs a method of sequentially stacking floors from a lower floor to an upper floor using a crane.

[0003]

In the case of the conventional building construction method described above, it is desirable to keep the production equipment fixed if possible, but there is no choice but to move it upwards and to the ground. It is necessary to have a transfer facility such as a construction elevator and a construction lift from the floor to the production floor (uppermost), and openings for that are left on each floor.

Therefore, the present invention has been made to solve the above problems of the conventional method of constructing a building, which is fixed to the above-ground portion of the production floor to eliminate the influence of weather and improve the construction speed. It is intended to provide a building method.

[0005]

According to the present invention, when constructing a building of a predetermined floor on a foundation on which foundation piles are laid in the ground, first, in the above-ground portion serving as the foundation, the roof and the top floor of the building are first constructed. Beam, floor, wall, outer wall mounting, etc.
The roof and the top floor are pushed up by one floor by a plurality of push-up devices provided between the beams between the pillars of the skeleton and the base, and then the skeleton is assembled one floor below the top floor in the above-ground portion. According to the above embodiment
It is characterized in that a building on a predetermined floor is constructed by pushing up the floors, and then similarly sequentially assembling and pushing up the frame of the lower floor.

Further, according to the present invention, the frame assembly is carried out on the above-ground part, and the equipment work is carried out on the upper floor.
It is characterized by finishing work on the upper floor.

Further, according to the present invention, the equipment and the finishing material are temporarily placed on the assembled body in the above-ground portion before the push-up of the building.

The above push-up device has four temporary columns standing on a base, a top beam provided on the top of the temporary column, four tension rods suspended from the top beam, and It is preferable that the tension rod is composed of upper and lower load bearing beams suspended by upper and lower rotary nuts at intervals, a hydraulic jack provided on the lower load bearing beam, and a temporary bearing girder.

[0009]

[Operation] A push-up device for the beam between the pillars of the building and the foundation is arranged, the temporary receiving girder is pulled out, the jack is extended, and the building is moved through one stroke (for example, 250 m) through the upper load bearing beam.
m) Push up. Next, the upper rotation nut is rotated up to support and fix the upper load bearing beam to the temporary column. Next, the jack is contracted, and the lower rotation nut is rotated up to bring the top surface of the jack into contact with the bottom surface of the upper load bearing beam.
In this way, the upper load receiving beam and the lower load receiving beam are alternately raised to the shakutake method, and when the building is pushed up by one floor, the temporary receiving girder is inserted to temporarily receive the building, the jack is removed, and the next Assemble the building frame.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

An example of a push-up device 20 used in the present invention is shown in FIGS. 1 to 5. This device 20 comprises four temporary columns 21 standing on the base 10.
A top beam 22 provided on the top of the temporary column body 21, four tension rods 23 suspended from the top beam 22 and partially formed with threaded portions, and upper and lower rotary nuts 24 on the tension rod 23. Upper and lower load-bearing beams 26 and 27 suspended at intervals of 25 and 25, a hydraulic jack 28 provided on the lower load-bearing beam 27, and a pair of top beams 22 which are orthogonal to each other and move laterally. It is composed of a pair of free temporary receiving beams 29. The rotating nuts 24 and 25 follow the upward movement of the load receiving beams 26 and 27 while rotating and prevent downward movement.

With this construction, when pushing up, as shown in FIG. 6, the top of the jack 28 is brought into contact with the upper load bearing beam 26 supporting the skeleton K.

Next, as shown in FIG. 7, when the jack 28 is extended, the skeleton K is raised via the upper load bearing beam 26, and at the same time, the upper rotary nut 24 is rotated following the rise of the upper load bearing beam 26. .

When the predetermined amount has been raised, the jack 28 is contracted to raise the lower load receiving beam 27. Then, the lower rotation nut 25 rotates following the rise.

When the jack 29 is contracted, as shown in FIG. 5, the temporary receiving girder 29 is moved to the side, and the temporary column 21 is moved.
This is performed by temporarily receiving the frame K on the bracket 29a protruding from.

[0046]

The present invention has the following effects.

Since the rooftop of the building is first completed and pushed up, there is a roof on each production floor (frame assembly floor, concrete construction floor, equipment construction floor, finishing floor), which is not affected by the weather. You can work on it.

Since the position of the production floor is fixed, it is not necessary to change the equipment for transferring materials from the ground according to the construction of the building.

Since the production floor is above ground, the influence of flying, dropping, noise, etc. from the work place does not reach the neighborhood.

Since the jack pushes up, the same construction speed can be maintained regardless of the height of the building.

Reinforcement for placing the construction machine on the floor of the first floor is only required for the first floor assembling floor (in the conventional method, the floor of each floor is reinforced). In addition, restrictions on the weight of the construction machine are alleviated.
