The invention relating to a steel frame building is characterized in that the piping constitutes a beam or a column.

Another invention related to a steel frame building is characterized in that the piping constitutes a beam or a column, and the piping is connected to a piping extending from a specific device.

Note that the pipe constituting the beam or column may be provided with a nozzle, a valve, a flange, and a flow rate measuring means for measuring the flow rate of fluid in the pipe.

Further, the invention relating to a method of utilizing piping is characterized in that the piping is used as a fluid transfer path and also as a beam or column of a steel frame building.

[Function] Since the beams and columns of steel-framed buildings are made of piping, they can be used as fluid transfer paths, and the piping and beams or columns can also be used as piping materials.

Manufacturing man-hours can be reduced.

In addition, since the length of the piping that simply serves as a fluid transfer path can be shortened, the number of piping support members such as piping brackets can be reduced, and the space within the building can be used effectively. .

For pipes that make up beams and columns that are equipped with nozzles or valves, or pipes that are connected to each other via piping flanges, it is necessary to operate the valves or install blind plates between the flanges. The fluid transfer path can be easily changed, and even if there are design changes such as changes in the routing of piping or the arrangement of equipment, it can be easily accommodated.

A first embodiment of the steel frame building will be described based on FIG.

The steel frame building is three stories high, with all beams and columns.

! i! It is made up of tubes.

First, the diameter, wall thickness, and material of these pipes are selected so that they can perform their original function as pipes.Furthermore, in order to function as building structural members, long-term loads,
That is, the diameter and wall thickness are selected so as to withstand stress and moment obtained through stress analysis that takes into account equipment loads, live loads, wind loads, dead loads, etc. As for the diameter and wall thickness, the larger value is finally selected between the required value for piping and the required value for architectural structural member.

The roof surface 50 and side wall surfaces 51 are formed of corrugated plates.

One piece of equipment 40 is installed on the second floor of the building.

An exhaust pipe 42 is connected to an exhaust nozzle 41 of the device 40, and a drain pipe 46 is connected to a drain nozzle 45.

The exhaust pipe 42 connects the exhaust nozzle 41 to the exhaust outlet valve 4.
3, and is connected to the third floor beam pipe 31 that constitutes the beam of the third floor 52. Exhaust pipes 42 and 3
It communicates with the floor beam piping 31.

The third-floor floor beam pipe 31 communicates with the side wall column pipe 10 that constitutes the column on the side wall surface 51 side, and does not communicate with the middle column pipe 20 that opposes the side wall column pipe 10.

The upper end of the side wall side column pipe 10 protrudes from the roof surface 50, and an exhaust port 11 is formed there.

The drain pipe 46 is connected from the drain nozzle 45 via a drain outlet valve 47 to the second floor beam pipe 32 that constitutes the beam of the second floor 53. The drain pipe 46 and the second floor beam pipe 32 are in communication.

The second floor beam piping 32 communicates with the center column piping 20 and does not communicate with the side wall piping 1o.

A buried drain collecting pipe 25 is connected to the base end of the middle column pipe 2o.

Both the exhaust pipe 42 and the drain pipe 46 are connected to the nearby floor beam pipes 31 and 32, have short pipe lengths, and do not require pipe brackets to support these pipes 42 and 46.

Steel-framed buildings use piping as structural members, but they are built with sufficient strength design and have the strength of a building.

, the exhaust gas from the equipment 40 is passed through an exhaust nozzle 41, an exhaust pipe 42, an exhaust outlet valve 43, and a third floor beam pipe 31. It passes through the side wall column piping 10 and is discharged into the atmosphere from an exhaust port 11 formed at the upper end of the side wall column piping 10.

The drain formed within the device 40 is drained through the drain nozzle 41 .
Drain outlet valve 47. The drain pipe 46° passes through the second floor floor beam pipe 32 and the middle column pipe 20, and is led to the buried drain collecting pipe 25.

Side wall side column piping 10. Middle column piping 20. 3rd floor floor beam piping 31.
The second floor beam piping 32 is used as a building structural member and is also used as a fluid transfer path as the original piping, so in order to guide the exhaust gas outdoors, the drain is routed to the drain collecting pipe 25. Therefore, there is no need to install separate piping.

Not only can piping materials be reduced, but also the number of manufacturing steps can be reduced. Furthermore, there is no need to route exhaust piping or drain piping within the building.

Not only can the number of piping brackets supporting the piping be reduced, but also a sufficient maintenance space and passage for the equipment 4o can be secured, and the space within the building can be used effectively.

Next, a second embodiment of the steel frame building will be described based on FIG. 2. In the description of this embodiment, the same parts as in the first embodiment are given the same reference numerals, and the explanation thereof will be omitted.

Nozzles 1 are installed at various locations on the middle column piping 20 and the side wall side column piping 20.
4.22 and each nozzle end is provided with a blind flange 15.23 or valve 24.

The flow rate of the drain of the equipment 40 is measured by an orifice built into the second floor beam piping 32.

The exhaust gas flow path formed by the center column piping 20 and the drain flow path formed by the side wall column piping 10 can be changed by opening and closing the valve 21 or by inserting and removing the blind plate 13.

Nozzles 14 are installed at various locations on the middle column piping 2o and the side wall side column piping 10.
．． 22, piping can be easily connected to the center column piping 20 and the side wall side column piping 10.
