Abstract

<P>PROBLEM TO BE SOLVED: To provide a column-beam frame capable of arranging facility and pipes satisfactorily without affecting a space in a living room adversely. <P>SOLUTION: This column-beam frame 10 dispenses a beam between columns 20 erected between a corridor and the living room and is provided with cantilever beams 40 protruding in three ways on the columns 20 in two ways. A beam 41 is stretched over between the cantilever beams 40 to support a floor slab 50 on an upper story by a beam 30 at the outer periphery of the column-beam frame 10 and the beam 41 stretched over between the cantilever beams 40. Consequently, a branched pipe 81 being branched from the facility pipe 80 is installed around a space in the living room on a corridor side more than a center side of the column 20, and it is unnecessary to provide the space for installing the branched pipe 81 around it in the living room. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT

Japanese Patent Laid-Open No. 2002-97715

  When piping is arranged as shown in FIG. 6, since the piping passes through the side of the beam on the side of the room, there is a problem that the space for passing the pipe protrudes into the room and the space in the room is cut accordingly. .

  Further, in the method of providing a through hole in the beam, it is necessary to increase the size of the beam so that the beam can have a predetermined strength, and the space in the living room is cut accordingly.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a column beam frame in which facility piping can be arranged without affecting the space in the living room.

The column beam frame of the present invention is a concrete column beam frame, wherein a plurality of columns are arranged in a straight line to form a street, and a first chamber is provided on one side across the street, A second chamber is provided on the side of the plurality of columns, and no beam is bridged between a pair of adjacent columns of at least a part of the plurality of columns. A second beam is bridged between a pair of first beams connected so as to extend toward the chamber side.

  In the above-mentioned column beam frame, the second chamber may be a living room or a room that requires air conditioning, and the first beam may be a cantilever beam.

  According to the present invention, since the beam is not bridged between the columns, the equipment piping can be routed in the space outside the room. Thereby, it can prevent that the space for surrounding equipment piping protrudes in a living room.

It is a perspective view which shows the structure of the column beam frame for one layer of this embodiment. It is a vertical sectional view showing arrangement of air conditioning equipment piping between a living room and a hallway. (A) is a vertical sectional view showing a conventional column beam frame, and (B) is a vertical sectional view showing a column beam frame of this embodiment. It is a perspective view which shows the structure of the column beam frame for another layer of another embodiment. It is a perspective view which shows the column beam frame in the conventional building. It is a figure which shows an example of a structure of the equipment piping in the conventional building.

Hereinafter, one embodiment of a column beam frame of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a configuration of a column beam frame according to the present embodiment. The column beam frame of the present embodiment is configured by stacking a plurality of column beam frames 10 having two spans in the Y direction and six spans in the X direction as shown in FIG. FIG. 1 shows only a column beam structure 10 for one layer. As shown in the figure, the column beam frame 10 has an outer circumferential beam 30 spanned between columns 20 over the entire outer circumference, and a beam 31 spanned between one or two columns 20. . Further, the cantilever 40 having a length shorter than the span length between the pillars 20 protrudes from the two pillars 20 in three ways. A beam is not bridged between two adjacent columns 20, and a beam 41 is bridged at the tip of the cantilever beam 40. An upper floor slab (not shown) is supported by these beams 30, 31 and 41. In the present embodiment, it is assumed that the space between the first street and the second street is used as a living room, and the space between the second street and the third street is partially used as a corridor.

  The long-term load acting on the floor slab is borne by the beams 30, 31, 41, and among these, the load borne by the beam 41 is transmitted to the column 20 through the cantilever 40, so that the conventional column beam structure Can support long-term loads as well as

  In addition, it resists the earthquake motion by the outer circumferential beam 30 in the X direction and resists by the outer circumferential beam 30 and the beam 31 spanned between one and two ways in the Y direction. Thus, the column beam frame 10 has sufficient strength as a support structure for the building.

  FIG. 2 is a vertical sectional view showing the arrangement of the air conditioning equipment piping 80 between the living room and the hallway. As shown in the figure, a branch pipe 81 branched from an air conditioning equipment pipe 80 arranged in the corridor extends in each room. The air conditioning equipment pipe 80 on the corridor side is arranged so as to extend in a direction along the corridor (a direction perpendicular to the paper surface in FIG. 2) at a lower height of the beam 41. A partition wall 60 is provided between the two columns 20. The branch pipe 81 extends in the horizontal direction from the air conditioning equipment pipe 80 toward the partition wall 60, bends upward, extends upward along the partition wall 60, bends in the horizontal direction again, and bends the floor slab 50 on the upper floor. It extends in the horizontal direction along and reaches the indoor air conditioner. A ceiling plate 70 is provided below the air conditioning equipment piping 80 on the corridor side, and a ceiling plate 71 is provided below the branch piping 81 on the living room side.

  Thus, in this embodiment, since the cantilever 40 which protrudes to the corridor side is provided in the two types of pillars 20 and the beam 41 is provided between the cantilever beams 40, from the corridor side toward the living room. The extending branch pipe 81 can pass under the beam 41 at a position closer to the hallway than the two columns 20. For this reason, the branch pipe 81 can be arranged along the lower surface of the ceiling slab 50 in the living room. Thereby, the space in the living room is not compressed due to the installation of the equipment piping as in the conventional case, and the space in the living room can be used effectively.

  Further, as shown in FIG. 3A, when a PC member is used for the ceiling slab 50 on the upper floor, the span between the beams 130 needs to be constant. For this reason, when the beam 130 is bridged between the columns 120, the column 120 must be arranged so as to be equal to the span of the beam 130, and it is difficult to widen the span S of the column 120. On the other hand, in this embodiment, since the beam is bridged between the cantilever beams 40, the span S ′ of the column 20 and the cantilever beam 40 in the same direction as shown in FIG. It is not necessary to match the span of the beam 31. Accordingly, by moving the position where the column 20 is provided according to the length of the cantilever 40 while keeping the span of the beam 31 constant, a space where the span S ′ of the column 20 is large can be formed.

  In the present embodiment, the case where the branch pipe 81 branched from the air conditioning equipment pipe 80 is described as an example. However, the present invention is not limited to this, and the present invention is also applied to the case where a smoke exhaust pipe or the like is arranged. it can.

  Moreover, although this embodiment demonstrated the case where the position of a beam was moved from the living room side to the corridor side, it is not restricted to this, For example, from the room which needs an air conditioning or air conditioning, for example, to space directions other than living rooms, such as a balcony The present invention can also be applied when moving the position of the beam.

  Moreover, although this embodiment demonstrated the case where the beam was not spanned between 2 to 3 ways, it is not restricted to this, Even when the beam is spanned between 2 to 3 ways, the present invention Can be applied. In this case, as shown in FIG. 4, a beam 41 may be bridged between the beams 31 spanned between two to three without providing a cantilever beam. In addition, when the beam 41 is bridged between two ways, it is not necessary to bridge the beam between one way and two ways.

  Moreover, although this embodiment demonstrated the case where the beam between all the two types of pillars was moved, it is not restricted to this, You may move only some beams.

  Further, in the present embodiment, the column beam structures of all the levels are assumed to have the same configuration. However, the present invention is not limited to this, and the present invention may be applied only to the column beam structures of some levels of the building. Good.

  Moreover, although this embodiment demonstrated the case where this invention was applied to the column beam frame of a reinforced concrete structure, this invention can be applied not only to this but to a steel-framed concrete structure and a steel-framed reinforced concrete structure building.
