Description

  The present invention relates to a building having wall columns that function as walls and columns.

For office buildings, etc., from the viewpoint of convenience, each floor is a non-column space (a space with no pillars exposed on the four sides) as shown in the perspective view of FIG. 1A. Is preferred. However, in order to obtain a column-free space, it is necessary to increase the cross section of the column 111 and the beam 121 from the viewpoint of securing the strength due to the long span of the beam.
In that case, first, due to the large cross section of the column 111, as shown in the cross sectional view of FIG. 1B, a part 111p (so-called column type) of the column 111 protrudes from the inner wall surface 191 of each floor to create a dead space. This may cause the efficient use of the indoor space SPr.
In this regard, as a reference technique, Patent Document 1 discloses a flat wall pillar functioning as a wall and a pillar.

JP 2006-70671 A

  And as shown in the cross-sectional view of FIG. 2A, if the wall pillar 11 is arranged along the outer periphery of the building instead of the pillar 111 described above, it is considered that the generation of the pillar mold 111p can be prevented. .

  On the other hand, one proposal for a method of increasing the cross section of the beam 121 is to increase the beam length of the beam 121. In this case, as shown in the longitudinal sectional view of FIG. The vertical cross-sectional shape of the vertically long beam 121 is further elongated. In such a case, if the ceiling height is to be secured, the floor height must be increased, and as a result, the overall height of the building increases and the construction cost increases. It was.

  Also, depending on the region, there are restrictions on the height of the building due to laws and regulations, etc.When building a building in such a region, the number of floors of the building must be reduced by the increase in the floor height, and the total floor There was a problem that the area would decrease.

It is a schematic longitudinal cross-sectional view of the X-axis beam 21x and Y-axis beam 21y which concern on this embodiment. FIG. 5A is a schematic cross-sectional view showing a preferred form of the wooden wall pillars 11x and 11y, and FIG. 5B is a schematic vertical cross-sectional view showing a preferred form of the wooden beams 21x and 21y. It is a schematic longitudinal cross-sectional view which shows the connection method of the wooden wall pillars 11x and 11y and the foundation 3. FIG. It is a schematic cross-sectional view of other embodiment of the building 1b.

=== This Embodiment ===
3A to 3C are schematic views of the building 1 of the present embodiment. 3A is a schematic cross-sectional view of the building 1, FIG. 3B is a side view thereof, and FIG. 3C is a CC cross-sectional view in FIG. 3A. 3A is also a cross-sectional view taken along line AA in FIGS. 3B and 3C.

  As shown in FIG. 3B, this building 1 is a four-story office building as an example of a plurality of floors, and has a foundation 3 made of reinforced concrete (hereinafter referred to as RC) embedded in the ground G. Although the upper surface 3a of the foundation 3 is generally formed in a horizontal plane, a part of the upper surface 3a may not be a horizontal plane. Hereinafter, the two directions orthogonal to each other in the horizontal plane are referred to as “X-axis direction” and “Y-axis direction” (see FIG. 3A).

  As shown in FIG. 3A, on the upper surface 3a of the foundation 3, a plurality of RC wall columns 11, 11,... Are erected along the outer periphery of the building 1 to be constructed. Are connected to a plurality of beams 21, 21,... Provided inside thereof, and function as a structural frame of the building 1 in cooperation with the beams 21, 21. In the example of FIG. 3A, the space defined on the foundation 3 by surrounding the plurality of wall pillars 11, 11... From the periphery is a no-column space with no pillars. A pillar may be provided. However, it goes without saying that a column-free space is preferred. Moreover, each wall pillar 11,11 ... is rigidly joined to the foundation 3. As shown in FIG. Here, the rigid joining is a joining method in which the joining state does not change even when an external force is applied. As a result, the bending moment is also quickly transmitted, and the tilting of each wall column 11 is effectively suppressed. Such a rigid joint is formed at the same position in the state in which, for example, the reinforcing bars of the foundation 3 and the wall column 11 are extended to the position of the joint and overlapped with each other when the joint portion of the foundation 3 and the wall column 11 is formed. This is realized by placing concrete on the surface and forming the joint. In this example, both the foundation 3 and the wall pillar 11 are made of cast-in-place concrete. However, the wall pillar 11 is not limited to cast-in-place concrete, and a precast concrete panel may be used. This will be described later.

  The planar shape of the outer periphery of the building 1 is a substantially rectangular shape having two short sides and two long sides, each short side is along the X-axis direction, and each long side is along the Y-axis direction. . In each of the short sides along the X-axis direction of the former, two wall pillars 11 and 11 as examples are intermittently provided in the X-axis direction while keeping the wall width direction along the X-axis direction. A plurality of three wall pillars 11, 11, 11 are arranged on the long side along the Y-axis direction, and the wall width direction is set to the Y-axis direction. It is arranged at a predetermined pitch intermittently in the Y-axis direction while being along. Hereinafter, each short side along the X-axis direction is referred to as “X-axis side”, and each long side along the Y-axis direction is referred to as “Y-axis side”. Further, the wall column 11 arranged with the wall width direction along the X-axis direction is referred to as “X-axis wall column 11x”, and the wall column 11 arranged with the wall width direction arranged along the Y-axis direction. This is called “Y-axis wall pillar 11y”.

  Incidentally, in this embodiment, the cross-sectional secondary moment in the wall width direction is larger than the cross-sectional secondary moment in the wall thickness direction in either the X-axis wall column 11x or the Y-axis wall column 11y. Is set. That is, for the X-axis wall column 11x, the cross-sectional secondary moment in the X-axis direction is set to be larger than that in the Y-axis direction, and for the Y-axis wall column 11y, the cross-sectional secondary moment in the Y-axis direction is larger than the X-axis direction. Is set larger.

  Each of these wall pillars 11x, 11y ... is formed with a length (hereinafter also referred to as a wall height) that extends over the entire floor in the height direction as shown in FIG. 3B. Since the building 1 is a four-story building, each of the wall pillars 11x, 11y... Has a wall height corresponding to a substantially four-story building. On the other hand, as shown in FIG. 3A, the wall thickness as a dimension in the wall thickness direction of each wall column 11x, 11y... Is naturally set smaller than the wall width as a dimension in the wall width direction.

  Also, as shown in FIG. 3A, each X-axis wall column 11x, 11x arranged on one X-axis side and each X-axis wall column 11x, 11x arranged on the other X-axis side are: The X-axis wall pillars 11x and 11x corresponding to each other are aligned along the X-axis direction in a state where the positions in the X-axis direction are aligned. Therefore, a pair of X-axis wall pillars 11x and 11x corresponding to each other are arranged to face each other with an interval in the Y-axis direction. Similarly, each Y-axis wall column 11y, 11y, 11y arranged on one Y-axis side and each Y-axis wall column 11y, 11y, 11y arranged on the other Y-axis side correspond to each other. The Y-axis wall pillars 11y, 11y are aligned along the Y-axis direction with the Y-axis direction positions aligned. Therefore, a pair of Y-axis wall pillars 11y and 11y corresponding to each other are arranged to face each other with an interval in the X-axis direction.

  A straight beam 21y along the Y-axis direction is bridged as a Y-axis beam 21y between the pair of X-axis wall columns 11x and 11x facing each other. A straight beam 21x along the X-axis direction is bridged between the Y-axis wall columns 11y and 11y as an X-axis beam 21x. Here, the installation positions in the height direction of the X-axis beam 21x and the Y-axis beam 21y are aligned, whereby the X-axis beam 21x and the Y-axis beam 21y are rigidly joined at the intersecting portion where they cross each other. ing. Therefore, the X-axis beam 21x is supported not only by the Y-axis wall column 11y spanned but also by the X-axis wall column 11x via the Y-axis beam 21y. Similarly, the Y-axis beam 21y is spanned by the X axis Not only the wall pillar 11x but also the Y-axis wall pillar 11y is supported via the X-axis beam 21x. That is, the X-axis beam 21x and the Y-axis beam 21y are respectively supported by both the X-axis wall column 11x and the Y-axis wall column 11y, and as a result, the downward deflection of each beam 21x, 21y is suppressed. As a whole, the strength of the beams 21x and 21y can be secured. Further, the rigidly joined X-axis beams 21x, 21x, 21x and the Y-axis beams 21y, 21y are lattice beams G21 assembled in a lattice shape in plan view as a whole, which also suppresses downward deflection. Contribute.

  The lattice beam G21 is arranged at a position slightly lower than the floor level of the corresponding floor for each floor, and the beam end of the X-axis beam 21x is rigidly joined to the Y-axis wall column 11y at the position. The beam end of the Y-axis beam 21y is rigidly joined to the X-axis wall column 11x. The rigid joint smoothly transmits the bending moment from the X-axis beam 21x to the Y-axis wall column 11y. Similarly, the bending moment is also transmitted smoothly from the Y-axis beam 21y to the X-axis wall column 11x. The downward deflection of the lattice beam G21 can be effectively suppressed.

  The X-axis beam 21x and the Y-axis beam 21y are made of, for example, cast-in-place concrete. In this case, the rigid connection between the wall column 11x (11y) and the beam 21y (21x) is performed when the junction between the wall column 11x (11y) and the beam 21y (21x) is formed. (11y) and the beam 21y (21x) are formed by extending the reinforcing bars of the beams 21y (21x) to the position of the joint and overlapping each other to form the joint at the same position. In addition, the rigid connection between the X-axis beam 21x and the Y-axis beam 21y is also performed when the X-axis beam 21x and the Y-axis beam 21y are formed with each other in the formation of the joint between the X-axis beam 21x and the Y-axis beam 21y. This is realized by extending the rebar to the position of the joint and placing the concrete in the same position in an overlapped manner to form the joint. However, the formation of the X-axis beam 21x and the Y-axis beam 21y is not limited to the cast-in-place concrete, and a precast concrete panel may be used, which will be described later.

  Each of the cross-sectional shapes of the X-axis beam 21x and the Y-axis beam 21y is a flat rectangular shape (horizontally long rectangular shape) whose beam width is larger than that of the beam as shown in the longitudinal sectional view of FIG. As a result, the beam 21x, 21y can have a large cross section by designing the beam width to be large, that is, the strength of the beams 21x, 21y can be secured without increasing the beam size. This makes it possible to secure the strength of the beams 21x and 21y while preventing an increase in floor height.

  In this example, the beam of the X-axis beam 21x and the beam of the Y-axis beam 21y are set to have the same size, and the lower surface of the X-axis beam 21x and the lower surface of the Y-axis beam 21y are flush with each other. It is arranged in. Thereby, the height dimension of the indoor space under the beam can be secured large over substantially the entire surface of the floor, and as a result, increase in the floor height can be prevented. However, it is not always necessary to have the same size, and the beam of one beam 21x (21y) may be slightly larger than the beam of the other beam 21y (21x). For example, when considering the downward deflection suppression of the beam 21, the beam length of the Y-axis beam 21y having a beam length longer than that of the X-axis beam 21x may be made larger than that of the X-axis beam 21x.

  Furthermore, in this example, as shown in FIG. 3A and FIG. 3B, the interval D between the X axis wall columns 11x and 11x adjacent in the X axis direction and the Y axis wall columns 11y and 11y adjacent in the Y axis direction. In the space D between each other, window frames 31, 31... Are installed across each floor or across a plurality of floors. As a result, a building 1 having a feeling of opening in a so-called vertical window style (an arrangement style in which one or more windows are arranged in a line in the vertical direction) is realized. A door may be provided for the interval D located on the first floor. Further, instead of all the window frames 31 or some of the window frames 31 to be arranged at the intervals D, D..., Glass damping walls (not shown) may be interposed at the intervals D. If it does in this way, the damping effect which suppresses the relative displacement between the adjacent wall pillars 11 and 11 other than the function as a window can also be show | played, and it becomes the building 1 excellent in the damping property. As an example of the glass damping wall, for example, a plate glass provided at the above-mentioned distance D and a wall glass 11, 11 that is adjacent to each other with the same distance D are provided on the opposing surfaces, respectively. And a viscoelastic body that supports its own weight.

  Further, by interposing a connecting member (not shown) made of a suitable steel material or the like at a distance D between the X-axis wall columns 11x, 11x, the X-axis wall columns 11x, 11x adjacent in the X-axis direction can be connected to each other. The relative displacement may be restricted by coupling, and similarly, by interposing a coupling member (not shown) made of a suitable steel material or the like in the interval D between the Y-axis wall columns 11y, 11y, The relative displacement may be regulated by connecting the Y-axis wall columns 11y, 11y adjacent in the axial direction. In this way, the strength and horizontal rigidity of the building 1 can be further increased.

  Furthermore, a vibration damping member (not shown) such as an oil damper may be interposed in these intervals D, D. According to this, when the wall columns 11 and 11 are relatively displaced, the vibration damping member absorbs the vibration energy related to the relative displacement, thereby suppressing the displacement of the wall columns 11 and 11. In addition to the oil damper, a friction damper, a viscous damper, a viscoelastic damper, a steel damper, or the like can be applied as the vibration damping member.

  Further, it is desirable that the X-axis wall column 11x and the Y-axis wall column 11y are not arranged in at least one of the four corners on the outer periphery of the building 1. For example, in the example of FIG. 3A, the X-axis wall column 11x and the Y-axis wall column 11y are not arranged at all four corners. And if it does in this way, the visibility in a corner part will become favorable and the building 1 with a feeling of opening is implement | achieved. For example, a window frame 31a having an L-shaped cross-sectional shape is arranged in this corner space, that is, the distance Da between the X-axis wall column 11x and the Y-axis wall column 11y located in the vicinity of the corner portion. The window frame 31a is fixed to the X-axis wall column 11x and the Y-axis wall column 11y near the corners, respectively. In addition, you may provide the above-mentioned glass damping wall, a connection member, a damping member, etc. in this space | interval Da.

  Further, when each X-axis side and each Y-axis side form the outer periphery of the building 1 as described above, preferably, an X-axis beam 21x is provided at a position adjacent to the X-axis side as shown in FIG. 3A. Similarly, it is preferable not to provide the Y-axis beam 21y at a position adjacent to the Y-axis side. If it does in this way, it will become difficult to see X-axis beam 21x and Y-axis beam 21y from the outside of building 1, and the design nature of the appearance of building 1 will become good. Further, the space adjacent to the X-axis side and the Y-axis side may be used as an installation space for indoor equipment such as a curtain box and a blind box.

  Preferably, as shown in FIG. 3A, the wall width as a dimension in the wall width direction of the X-axis wall column 11x and the beam width of the Y-axis beam 21y are designed to be equal to each other, and the Y-axis wall column The wall width as a dimension in the wall width direction of 11y and the beam width of the X-axis beam 21x may be designed to be the same size. In this way, when forming the joint portion between the X-axis wall column 11x and the Y-axis beam 21y and the joint portion between the Y-axis wall column 11y and the X-axis beam 21x by the cast-in-place concrete, the formwork is arranged. It becomes easy. Moreover, construction accuracy improves with the improvement of this workability.

  Incidentally, as shown in FIG. 3C, the floor portions 41, 41... On the second and higher floors are respectively provided on the corresponding lattice beams G21 (X-axis beams 21x, 21x, 21x and Y-axis beams 21y, 21y). And each floor part 41, 41 ... has a horizontal surface on the upper surface. In such a floor portion 41, its lower surface may be brought into contact with the upper surface of the lattice beam G21 so as to be substantially integrated, but in some cases, as shown in FIG. 3C, a free access floor (OA floor) or the like. A double floor structure may be adopted. The double floor structure is, for example, arranged with a space between a plurality of columns (not shown) discretely erected on the upper surface of the lattice beam G21 and the upper surface of the lattice beam G21 while being supported by these columns. And a plurality of panel members that become the double floor portion 41. According to such a double floor structure, the space SP41 partitioned between the lattice beam G21 and the panel member is used as an accommodation space SP41 for various equipment such as electric wiring, gas and water pipes, and air conditioning ducts. be able to.

  Further, each grid-like space SP21, SP21,... Of the lattice beam G21 shown in FIG. 3A is provided as an installation space for the illumination unit 51 and the air conditioning unit 52 in FIG. 3C. As a result, the lower surface heights of these units 51 and 52 can be substantially flush with the lower surface heights of the X-axis beams 21x, 21x and 21x and the Y-axis beams 21y and 21y forming the lattice beam G21. As a result, even under the arrangement of these units 51 and 52, the ceiling height of the indoor space can be maintained high over substantially the entire surface. Incidentally, the air conditioning unit 51 has an air outlet and an inlet, and these outlet and inlet are connected to an air conditioning duct (not shown) for air conditioning. For example, it is accommodated in the accommodation space SP41 of the above-mentioned double floor structure equipment.

  When this building 1 is the main building 1, as shown in FIG. 3A, another building 1a may be provided next to the main building 1. This annex 1a is, for example, a building 1a having a staircase, an elevator, a toilet, and the like inside. For each floor, the floor 41 of the main building 1 and the floor 41a of the separate building 1a are connected by a crossing corridor 61, so that people can come and go. In the example of FIG. 3A, since the separate building 1a is built next to the main building 1 in the Y-axis direction, the crossing corridor 61 extended from the separate building 1a has the X-axis wall pillar 11x, It spans the interval D between 11x. That is, the interval D may be used as an installation space for a communication passage member such as the passageway 61. Moreover, what is called connection vibration suppression may be performed by connecting between the main building 1 and the another building 1a with vibration damping members (not shown), such as an oil damper. That is, if the natural period of horizontal vibration is set differently between the main building 1 and the separate building 1a, when the main building 1 and the separate building 1a are horizontally displaced, relative displacement occurs between each other. If the relative displacement is input to the damping member, the vibration energy of the relative displacement is converted into thermal energy and the like, and the relative displacement is attenuated, thereby suppressing the horizontal displacement of the main building 1 and the separate building 1a.

  By the way, in the above-described embodiment, not only the foundation 3 of the building 1 but also all of the X-axis wall column 11x, the Y-axis wall column 11y, the X-axis beam 21x, and the Y-axis beam 21y are made of cast-in-place concrete. However, it is not limited to this. For example, the wall pillars 11x and 11y and the beams 21x and 21y may be formed using precast concrete panels (hereinafter referred to as PC panels).

  In that case, the X-axis wall column 11x, the Y-axis wall column 11y, the X-axis beam 21x, and the Y-axis beam 21y are each preferably divided into a plurality of PC panels. If the unit of division is the former wall pillars 11x and 11y, for example, for each floor or a plurality of floors, and if the latter is the beams 21x and 21y, for example, in the one grid-like space SP21 of FIG. Every adjacent part.

The connection between the PC panels is performed as follows, for example. First, in the PC panel, on the surface to be abutted at the time of connection (hereinafter referred to as a butting surface), ends of a plurality of reinforcing bars arranged inside the PC panel protrude, and the abutting surface includes: A joint sheath for inserting the ends of a plurality of reinforcing bars protruding from the abutting surface of the counterpart PC panel to be abutted is embedded. The joint sheath is connected to a reinforcing bar in the PC panel in which the sheath is embedded. Then, when the PC panels to be connected are abutted at each abutment surface, the ends of the mating reinforcing bars are inserted into the joint sheaths of their abutment surfaces, and mortar is used as an adhesive. The surfaces are joined to each other, whereby the PC panels are rigidly joined.
In addition, the rigid joint between the X-axis wall column 11x and the Y-axis beam 21y, and the rigid joint between the Y-axis wall column 11y and the X-axis beam 21x are also inserted into the joint sheath of the reinforcing bar and an adhesive as described above. In addition, the rigid connection between the foundation 3 and the X-axis wall column 11x and the rigid connection between the foundation 3 and the Y-axis wall column 11y are also performed using the same method as described above. .

  By the way, in the above-mentioned embodiment, although the building 1 was formed by RC structure, it is not restricted to this at all. For example, the X-axis wall column 11x, the Y-axis wall column 11y, the X-axis beam 21x, and the Y-axis beam 21y may be made of wood. However, the foundation 3 is made of RC.

  Here, desirably, as shown in the cross-sectional view of FIG. 5A, the X-axis wall column 11x and the Y-axis wall column 11y are configured in a layer structure having a plurality of layers from the column center side toward the outside, and The load supporting layer L11a is a wooden load supporting layer L11a for supporting the load, and a dead end layer L11b (about 3 cm with 1 hour fire resistance) provided outside the load supporting layer L11a so as to surround the load supporting layer L11a. It is preferable to have a wood burnt layer L11c (about 5 to 6 cm in 1 hour fire resistance) provided so as to surround the burnout layer L11b outside the burnout layer L11b.

  Similarly, the X-axis beam 21x and the Y-axis beam 21y are also configured with a layer structure having a plurality of layers from the beam center side toward the outside, as shown in the longitudinal sectional view of FIG. 5B, and As a layer, a wooden load support layer L21a for supporting a load, a flame stop layer L21b provided outside the load support layer L21a so as to surround the load support layer L21a, and a flame stop on the outside of the flame stop layer L21b It is preferable to have a wood burnt layer L21c provided so as to surround the layer L21b.

  According to such a layer structure, before any of the X-axis wall column 11x, the Y-axis wall column 11y, the X-axis beam 21x, and the Y-axis beam 21y reaches the load supporting layers L11a and L21a. Combustion is stopped at the non-burning layers L11b and L21b, whereby the spread of fire to the load supporting layers L11a and L21a is prevented, and the soundness of the structural frame of the building is maintained.

Examples of the wood used for the load support layers L11a and L21a and the burn-off layers L11c and L21c include wood such as rice pine, karamatsu, firewood, cedar and asunaro (hereinafter referred to as general wood).
Further, as the flame-stopping layers L11b, L21b, for example, a high heat capacity material having a larger heat capacity (heat absorption amount) than the above general wood, a heat-insulating material made of non-combustible material and having heat insulation properties, flame retardant treated wood or the above general wood Different materials such as tree species with high thermal inertia are used. Here, examples of the high heat capacity material include inorganic materials such as mortar, stone, glass, fiber reinforced cement, and various metal materials, as well as inorganic materials, liquid metals, water, and inorganic materials in hollow rectangular metal pipes. Examples thereof include a material that is integrated with a heat storage material such as hydrated salt or slaked lime. Moreover, as a heat insulating material which is made into a nonflammable material and has heat insulating properties, for example, calcium silicate plate, rock wool, glass wool and the like can be mentioned. Examples of the wood having higher thermal inertia than the above general wood include Selangan Batu, Jara, Bongosi and the like.

  Even in the case of the wooden structure, the X-axis wall column 11x, the Y-axis wall column 11y, the X-axis beam 21x, and the Y-axis beam 21y may be divided in the same units as those of the PC panel described above. . And the connection between such panels, for example, while inserting a difference such as an iron plate or a steel bar across the panels into a recess formed in each abutting surface to be abutted at the time of coupling, as appropriate, such as a bond for woodworking This is done by jointly joining the butted surfaces using a combination of adhesives, whereby the panels are rigidly joined. Note that the rigid joint between the X-axis wall column 11x and the Y-axis beam 21y and the rigid junction between the Y-axis wall column 11y and the X-axis beam 21x are also performed by using the same combination of the difference material and the adhesive as described above. Made.

  However, since the foundation 3 is made of RC as described above, the rigid connection between the foundation 3 and the X-axis wall column 11x and the rigid connection between the foundation 3 and the Y-axis wall column 11y are shown in the longitudinal sectional view of FIG. As shown in FIG. 5, for example, the metal piece 71 is used which is fixed across the foundation 3 and the wall pillars 11x and 11y. The hardware 71 is a steel member 71 having an L-shaped longitudinal section integrally including a horizontal plate portion 71a and a vertical plate portion 71b, and the horizontal plate portion 71a of the steel member 71 is applied to the upper surface 3a of the foundation 3. The vertical plate 71b is brought into contact with the vertical wall surface 11b of the wall pillars 11x and 11y and fixed to the vertical surface 11b with the fastening member 73. And the rigid joining of the foundation 3 and wall pillar 11x, 11y is implement | achieved by providing this steel member 71 with respect to the vertical wall surfaces 11b, 11b of the both sides of wall pillar 11x, 11y, respectively.

  Incidentally, the above-described connection method between panels, that is, a connection method using a difference and an adhesive can also be applied to the above-described connection of PC panels.
