DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called SRC steel column in which a hollow rectangular steel to be erected and a reinforced concrete are integrated, and is also used as a rainwater storage tank. The present invention relates to a water column construction method in which a rooftop water gradient can be obtained with only a small thickness of concrete, and is used for preventing flood damage, and rainwater is recycled for cooling and heating.

[0002]

2. Description of the Related Art In a steel-frame building, a so-called SRC steel column made by integrating square steel and reinforced concrete is conventionally used to take a rooftop water gradient. The work was troublesome because the joint at the top for receiving the roof beam was welded to the angle of the water gradient according to the design. Furthermore, since there is a large amount of rainfall flowing down from the rooftop, it is mandatory to install a prescribed amount of water storage tanks according to the rooftop area.

The receiving joint 3 at the top, which takes the angle of the water gradient,
In the past, because of the on-site construction after the pillars, it took time and labor to complete the work, and the length of each square steel became longer toward the center, so there were drawbacks such as a higher unit price for materials.
In addition, after the enforcement is completed, rainwater discharged by the rooftop water gradient will be released, and even if a water tank is installed, an extra large amount of rainwater will flow to the concrete pavement surface above the ground and cause flood damage. There are also problems, and there are many problems, such as the fact that the economic burden of installing a water tank is quite large.

SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems, and a square steel serving as a core is a hollow square steel having a hollow inside, and rainwater is introduced into each hollow portion. Put it in and serve as a water tank, eliminating the need for a specially large water tank,
Each hollow square steel has the same height dimension, eliminates the angle gradient of the joint, saves material and simplifies the work of work, and the water gradient that guides rainwater to each hollow part on the roof is
The difference in concrete thickness is to be taken.

[0005]

SUMMARY OF THE INVENTION According to the present invention, in a steel frame high-rise building, each hollow square steel 2 of a so-called SRC steel column 1 for integrating a hollow square steel to be erected and reinforced concrete is made to have the same height, In order to eliminate the angular gradient of the joint 3 that fixedly supports the beam 5 on the roof, and to make the hollow portion of each hollow square steel a water column that also serves as a water storage tank, the water gradient that guides rainwater to each hollow portion is individually set. It features a construction method that takes the difference in concrete thickness 4 of the roof slab floor.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In a high-rise steel building, the height of the steel column as a core is changed to take a water gradient on the roof surface, so that the unit price of the square steel as the steel column increases, There was a problem that the work process was lengthened and rainwater flowing down to the ground caused flood damage. However, the present invention has solved this problem, and is a so-called SRC steel column 1 that integrates a hollow rectangular steel column and reinforced concrete. In order to make each hollow square steel 2 of the same height dimension, to eliminate the angular gradient of the joint 3 for fixedly supporting the beam 5 on the roof, and to make the hollow portion of each hollow square steel a water storage column also serving as a water storage tank It is characterized by the construction method of taking the water gradient that guides rainwater into each hollow part by the difference of the concrete thickness 4 of the roof slab floor, and the height of the steel columns is the same size. The unit price is considerably lower, and beams 5 on the roof The angle gradient of the inheritance hand 3 fixed support is not necessary, since the labor of tool operations is simplified, the working process is shortened.

[0007] The hollow rectangular steels serving as the cores of the steel columns arranged in a lattice pattern at the design intervals also serve as water storage tanks. Therefore, the water gradient on the rooftop surface for guiding rainwater to the respective top openings is as follows:
A slight gradient is created around each hollow square steel by changing the thickness of the slab floor concrete, and a water gradient is taken for each hollow square steel. Therefore, compared to the conventional method of taking a water gradient,
Extremely easy and cost saving.

[0008] The amount of rainwater that can be stored in the hollow square steel is considerable with respect to the rooftop area. For example, when the hollow area of the hollow square steel is 350 mm square, 14 m in height, and 34 steel columns in the vertical direction corresponding to the rooftop area and 10 steel columns in the width direction, there are 340 1.715 m ³ , The amount of rainwater that can be stored is 583m ³ , which plays a part in the water storage tank.

Each hollow square steel is provided with an overflow pipe with a valve, and a valve is opened by a sensor to release the overflow. The rainwater stored in each hollow square steel of the steel column is removed by summer if necessary. Is used for cooling and heating in winter, which is useful for energy-saving recycling. Also, the cross section of the hollow square steel 2 serving as the core of the SRC steel column 1 is not necessarily limited to a square shape, and may be a round shape.

[0010]

According to the present invention, rainwater is stored in each hollow square steel of a steel column of a high-rise building to serve also as a water storage tank. Since each hollow square steel has the same height dimension, steel material is used. It is possible to save money, it is not necessary to use a water gradient angle of the joint, and it is easy to work and the construction period can be shortened. The work is extremely easy, cost is saved, and the stored rainwater has the effect of preventing flood damage, being recyclable and useful for energy saving.
