Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural structure capable of efficiently constructing an equipment piping area for installing ducts and various equipment pipes.

[0002]

2. Description of the Related Art As semiconductors become more highly integrated, the manufacturing area of a semiconductor factory for manufacturing semiconductor devices is required to be constructed as a clean room requiring a high degree of cleanliness of indoor air. . Therefore, in order to maintain the cleanliness of a clean room, a method of circulating the air that has been cleaned through a filter throughout the room using an air conditioner or the like is widely adopted. In order to circulate air, it is necessary to arrange a large-diameter duct so as to penetrate from the clean room to the air conditioner room.

On the other hand, semiconductor factories are often constructed using a ramen structure constructed by combining columns and beams, or a brace structure obtained by adding a brace to the ramen structure. It has been common practice to dispose them by avoiding beams, braces, and the like, or to dispose them by providing through holes in the beams and inserting the through holes.

[0004]

However, when the above-mentioned ramen structure is adopted, since a relatively large spare space is provided, a duct can be arranged in the spare space. The cross section became large, and the construction cost was to be increased. In addition, when the brace structure is adopted, the cross section of the column and the beam becomes small and the economy is excellent as compared with the case where the ramen structure is adopted, but the brace is hindered when arranging the duct. In many cases, countermeasures must be taken, which places great restrictions on where to place the ducts. In addition, similar problems have arisen when providing various facility piping for performing production exhaust, drainage, and the like, in addition to the duct.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and efficiently maintains an installation area for installing ducts and various equipment pipes while maintaining a predetermined structural strength. It is intended to provide an architectural structure that can be constructed.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a double horizontal member disposing structure of the present invention is directed to forming a horizontal member and an equipment pipe disposing area below the horizontal member. And another horizontal member provided on the second member.

[0007] Here, the horizontal member is a member arranged in a horizontal direction in a structure, and refers to a structural member such as a beam. In addition, the structure provided with the double horizontal member arrangement structure may be a structure having a plurality of floors, and the position may be one or more. Further, the equipment piping arrangement area is an area provided for arranging ducts and various equipment pipes, and is provided for only ducts, only various equipment pipes, or for collectively arranging both. Therefore, it is preferable to set the interval between the horizontal members to a minimum dimension that allows various pipes and the like to be disposed therebetween in order to reduce the earthquake resistance of the structure and the construction cost.

Therefore, according to the present invention, by providing another horizontal member below the horizontal member, a facility piping area can be formed between the two horizontal members. In addition to being able to collectively arrange various equipment pipes and the like in the equipment pipe arrangement area,
It can be arranged with a degree of freedom.

Further, in the double horizontal member arrangement structure, the double horizontal member is arranged so as not to enter the equipment piping arrangement area.
The horizontal member or another horizontal member may be provided with a stiffening member. Here, so as not to enter the equipment piping arrangement area means that the stiffening member is joined to the upper edge without projecting from the lower edge of the horizontal member,
Or, it means that the stiffening member is provided so as not to protrude into the facility piping arrangement area by being joined to the lower edge without protruding from the upper edge of another horizontal member.

Therefore, according to the present invention, the stiffening member is provided by arranging the stiffening member of the horizontal member or another horizontal member so as not to enter the facility piping arrangement region. A structure excellent in rigidity capable of effectively resisting horizontal force during an earthquake without disturbing the arrangement of equipment piping and the like can be provided.

Further, in the double horizontal member disposing structure, the horizontal member and the other horizontal member may be joined by a predetermined joint structure via a vertical member. Here, the predetermined structure is generally to perform a rigid joint or a pin joint, but it is to appropriately adjust the rigidity of the joint according to the type of the structure, and it is also possible to use both together. it can.

Therefore, according to the present invention, it is possible to apply the present invention to various structures by joining a horizontal member and another horizontal member with a predetermined joining structure via a vertical member. Also, when the horizontal member and another horizontal member are rigidly connected via the vertical member, rigidity against horizontal force in the equipment piping arrangement area can be secured, and the cross-sectional shape of the horizontal member is reduced. Since the size can be reduced, the construction cost can be effectively reduced.

[0013] In addition, when the vertical member is a steel pipe member or an H-shaped steel member, the rigidity against the horizontal force in the equipment piping arrangement area can be further effectively improved even when the stiffener is not present. Can be secured.
