Description

  The present invention relates to a building having an outer frame as a structural frame and a construction method thereof.

  As a structural form of a building such as an office building, a ramen structure as shown in a perspective view of FIG. 1A is generally used. Further, from the viewpoint of convenience, it is desirable that each floor is a non-column space (a space having no columns with four side surfaces exposed in the room) over one floor as shown in FIG. 1A. This column-free space is generally achieved by standing the columns 111, 111... Only on the outer periphery of each floor and making the beams 121, 121. However, in that case, since the beam 121 and the column 111 are enlarged for the reason of strength, as shown in the plan sectional view of FIG. 1B, a part 111p of the column 111 from the inner wall surface 191 of each floor ( A so-called columnar shape) and a part 121p of the beam 121 protrude, and efficient use of the indoor space SPr on the floor is hindered. For example, it becomes easy to make a dead space such that it is difficult to place an object around the wall surface 191 from which a part 111p of the column 111 protrudes. Further, as the beam 121 becomes larger in cross section, the beam becomes larger, so that the ceiling height may be lowered for the floor height.

  In this regard, Patent Document 1 describes that an outer frame of a building is formed by arranging a plurality of RC (steel reinforced concrete) PC panels along the outer periphery of the building. For example, a column-free space can be formed inside the outer frame.

JP 2006-291477 A

  However, in the method of Patent Document 1, there is a restriction on the exterior design such that the window arrangement pattern is limited to the vertical window format. That is, the outer frame is formed by arranging a plurality of PC panel groups in which a plurality of PC panels are stacked upward along the outer periphery of the building. At this time, the PC panel groups adjacent to each other in the outer peripheral direction of the building are connected and integrated by a boundary beam while being spaced apart in the outer peripheral direction. However, the window arrangement pattern is limited to the vertical continuous window, and the windows cannot be freely arranged.

  In addition, this Patent Document 1 specifically describes the formation of the outer frame by an RC PC panel, but does not specifically describe the formation of the outer frame by a steel frame. Here, if the outer frame is made of steel, the strength can be improved compared to the RC structure with the same cross-sectional size. Therefore, the cross-sectional size can be reduced by this strength improvement, and as a result, the space inside the outer frame is reduced. It can be further expanded. Furthermore, the steel frame is lighter than the RC structure, so the weight of the outer frame can be reduced to improve seismic resistance, and the liftability during construction of the outer frame will be better, making it easier to install. It is thought that it becomes.

  The present invention has been made in view of the conventional problems as described above, and an object thereof is related to a building having an outer frame, expanding a space partitioned inward of the outer frame, and arranging windows or the like.

As a result, it is possible to reduce the amount of protrusion of the frame member into the internal space that is the inner space of the outer frame (for example, the amount of protrusion of the column member or beam member included in the frame member), and to widen the internal space. it can. In addition, since the beam of the beam member related to the frame member can be reduced, a high ceiling height can be secured for the floor height, which also contributes to the expansion of the internal space.
Moreover, since the frame member is made of steel, the weight of the outer frame can be reduced. Therefore, it is possible to improve the seismic resistance, and the frame member at the time of construction also has good liftability, so that construction is easy.

  Furthermore, since the frame member is assembled in the Feelendale format, it has a plurality of rectangular openings.

=== First Embodiment ===
FIG. 2 is a schematic perspective view of the building 5 of the first embodiment. 3A to 4B are explanatory diagrams of the construction procedure of the building 5. FIG. In FIG. 2 and FIG. 4B, a part of the structure of the building 5 such as an outer wall material and a roof material is omitted.

  This building 5 is a two-story office building as an example of a plurality of floors, and is constructed on a concrete foundation 3 embedded in the ground G. The building 5 has a steel frame outer frame 10 continuously arranged in an annular shape along a portion corresponding to the outer periphery of the building 5 to be constructed on the upper surface of the foundation 3 as a structural frame, and an outer periphery. And a plurality of steel beam members 50, 50... (See FIG. 4A) provided across a space partitioned inward by the frame 10 (hereinafter also referred to as an internal space SP10). The beam members 50, 50... Are provided with a floor 60 for the second floor, a roof material (not shown) is provided on the upper part of the outer frame 10, and further, not shown on the side of the outer frame 10. Outside wall materials and window frames are provided.

  The foundation 3 has a planar shape larger than the planar outline of the building 5. The foundation 3 is embedded with a steel material (not shown) for fixing the outer frame 10 to the foundation 3. Therefore, for example, the outer frame 10 is integrally connected to the foundation 3 by rigidly joining the column members 11 of the outer frame 10 to the steel material. Incidentally, the rigid joint is a joint system in which the joint state does not change even when an external force is applied, whereby the bending moment is also transmitted promptly. This rigid joining is realized by welding joining or bolt joining.

  The outer frame 10 is formed by assembling a plurality of steel pillars 11, 11,... And a plurality of steel beams 21, 21,. Yes. The Feelendale format is a kind of ramen structure format in which the column material 11 and the beam material 21 are rigidly joined, and is a framework structure format based on a quadrangle. Therefore, basically, the column member 11 is provided with its longitudinal direction oriented in the vertical direction, and the beam member 21 is provided with its longitudinal direction oriented in the horizontal direction, and the outer frame 10 in the example of FIG. Has a plurality of rectangular openings OP, OP,... On the outer peripheral surface thereof in a substantially lattice shape as a whole.

These openings OP, OP... Can be provided with window frames to be used as windows, or can be closed with outer wall materials to form outer walls. It can be a continuous window or a checkered pattern.
Further, since the column member 11 and the beam member 21 can be used as a support member for exterior finishing materials such as window frames and outer wall materials, the exterior marion can be reduced.

  Each column member 11 is intermittently arranged along a direction along the outer periphery of the building 5 (hereinafter also referred to as a building outer peripheral direction). Each column member 11 is rigidly joined to the steel material of the foundation 3 at the arrangement position thereof, and is connected and integrated with the foundation 3 thereby. Further, the column members 11 adjacent to each other in the building outer peripheral direction are connected by a beam member 21. A plurality of beam members 21 are arranged intermittently in the vertical direction. For example, in the illustrated example, one beam member 21 is provided at each of the upper and lower ends of the column member 11, and five beam members 21, so as to divide the range between them into six equal parts as an example. 21 ... are arranged. As a result, the space between the adjacent column members 11 is divided into six openings OP, OP.

  More specifically, in the enlarged three-side view (side view, top view (BB view in the side view), longitudinal view (CC view in the side view)) of the outer frame 10 in FIG. As shown, the adjacent column members 11 and 11 are opposed to each other with a surface 11fs, and a beam member 21 is interposed between the surfaces 11fs and 11fs, and the edge ends of both ends of the beam member 21 are disposed. The surface 21ss is rigidly joined in such a manner that the surface 21ss abuts the surface 11fs. For example, as will be described later, here, H-section steel is used as the column member 11 and the beam member 21, but the column members 11, 11 adjacent to each other in the outer peripheral direction of the building face the flange surfaces 11fs, 11fs. The H-shaped small facet 21ss of the beam 21 is abutted against the flange surface 11fs and is rigidly joined by welding or bolting. And thereby, the protrusion of the column material 11 and the beam material 21 to the internal space SP10 of the outer frame 10 is effectively suppressed, and the internal space SP10 is expanded. It should be noted that a diaphragm (not shown) is appropriately provided over the pair of flanges 11f, 11f and the web 11w of the H-shaped steel of the column member 11 so that the connecting portion of the beam member 21 in the column member 11 is reinforced. good.

  Moreover, in the example of FIG. 2, the planar external shape of the building 5 is a rectangle. Therefore, with the four sides of the building 5 as the outer periphery, the column members 11, 11,... Are erected at substantially equal pitches along the sides. However, the planar outer shape of the building 5 is not limited to this, and may be, for example, an L-shaped outer shape in plan view having an entrance corner outdoors, a polygon other than a rectangle such as a triangle, or a circular shape. Alternatively, it may be a composite shape formed by combining a plurality of these polygons and circles.

By the way, in the present invention, from the viewpoint of improving workability at a construction site, the column members 11, 11 and the beam members 21, 21,... As an example of the frame member F10, a ladder-like frame member F10 is assembled into a unit. That is, as shown in the three views (side view, top view (BB view in the side view), vertical sectional view (CC view in the side view)) of FIG. F10 is a pair of pillar materials 11 and 11 having a length corresponding to the height of the second floor as an example of a plurality of floors, and is arranged horizontally and intermittently in the vertical direction so as to connect the pair of pillar materials 11 and 11. A plurality of (in this case, seven) beam members 21, 21,...
Then, these frame members F10, F10... Are carried into the construction site, intermittently arranged along the respective sides as the outer periphery of the building 5 as shown in FIG. 3A and fixed to the foundation 3, and then the building as shown in FIG. The frame members F10 and F10 adjacent to each other in the outer peripheral direction are sequentially connected to each other via a steel connecting member J10, whereby the outer frame 10 is formed.

  In the example of this figure, seven beam members 21 of the frame member F10 are provided in order to divide the space between the pair of column members 11 and 11 into six openings OP. This is because the space between the column members 11 adjacent to each other in the outer frame 10 is divided into six openings OP, OP.

  Further, in the example of FIG. 6, the height position of the small edge surface 11 ss of the upper end portion of the column member 11 is aligned with the upper surface 21 us of the uppermost beam member 21 in the vicinity thereof, and the lower end portion of the column member 11 Although the height position of the small edge surface 11ss is aligned with the lower surface 21ds of the lowermost beam member 21 in the vicinity thereof, it is not limited to this at all. Alternatively, the beam member 21 may be slightly protruded in the vertical direction from the upper surface 21us and the lower surface 21ds of the beam member 21.

  As shown in the schematic top views of the outer frame 10 in FIG. 3B and FIG. 7, the connecting member J10 is basically a beam member 21 that is straight in the horizontal direction, like the beam member 21 of the frame member F10. Is done. For example, the connecting member J10a disposed at a portion other than the four corners 5c of the building 5, that is, the connecting member J10a disposed at each of the four sides of the building 5, has straight beams 21 (“second Equivalent to “beam”. Thereby, the inner wall surface which should be formed in each side later can be made into a substantially flat surface without a protrusion part. On the other hand, in the connecting member J10c arranged at the four corners 5c of the building 5, the beam member 21c (with an L-shaped bent portion corresponding to the shape of each corner 5c ( "Corresponding to" second beam material ") or L-shaped beam material 21c (corresponding to" second beam material ") and straight beam material 21 (" second beam material ") Or a member formed by rigid joining to the column member 11 is used.

  Desirably, the connecting members J10a disposed on the respective sides are beams having exactly the same specifications (that is, the same cross-sectional shape and the same length) as the beam member 21 of the frame member F10, as shown in FIG. The material 21 may be used, and the installation height and the number of installations in the vertical direction may be aligned with the beam material 21 of the frame member F10. Then, as shown in the side view in FIG. 5, the portion between the frame members F10 and F10 in the outer frame 10 is also a ladder having the same specifications as the frame member F10. It is possible to prevent the strength and rigidity of the outer frame 10 from changing according to the position. In addition, the beam members 21c and 21 of the connecting member J10c arranged in the corner portion 5c should also have the installation height and the number of installations in the vertical direction aligned with the beam members 21 of the frame member F10. Since the corner portion 5c also has a ladder-like specification substantially similar to that of the frame member F10, the strength and rigidity of the outer frame 10 can be made substantially uniform over substantially the entire circumference in the building outer peripheral direction.

  In addition, when the cross-sectional shape of the column 11 has a strong axis direction and a weak axis direction that is perpendicular to the strong axis direction and has a smaller secondary moment of section than the strong axis direction, Desirably, the strong axis direction of the pillar 11 may be aligned with the outer peripheral direction of the building. In the example of FIG. 5, an H-section steel is used as the column material 11, and the strong axis direction of the H-section steel is a direction parallel to the web surface 11 ws of the H-section steel. This is the normal direction of the flange surface 11fs. Therefore, as shown in FIG. 7, the column member 11 is arranged so that the web surface 11ws is along the building outer peripheral direction. In other words, the column member 11 is such that the normal direction of the flange surface 11fs is along the building outer peripheral direction. Is arranged.

  And if the strong axis direction of the pillar material 11 is made to follow a building outer peripheral direction in this way, the rigidity and intensity | strength of the pillar material 11 can be raised to the direction along the outer periphery of the outer periphery frame 10, and the outer periphery frame 10 as a whole. Can improve horizontal rigidity and horizontal strength. As a result, the cross-sectional size of the column 11 can be reduced by an amount corresponding to the improvement in rigidity and strength. Enlargement and enlargement of the square opening OP according to the Feelendale format can be achieved.

  In the example of FIG. 7, the strong axis direction is aligned with the building outer peripheral direction for all the column members 11, 11... That the outer frame 10 has, but this is not restrictive. .. For some of the column members 11, 11,..., The strong axis direction does not need to be along the building outer peripheral direction. . For example, the strong axis direction of the pillar material 11 may be along the building outer peripheral direction every other one or plural along the outer peripheral direction of the building, or at least one column per each of the four sides of the building 5 You may make it make the strong axis direction of the material 11 follow a building outer peripheral direction.

  Further, the column member 11 is not limited to H-shaped steel, but may be groove-shaped steel or a steel pipe having a rectangular cross section.

  Further, as to which direction the strong axis direction is directed, the beam member 21 of the frame member F10 and the beam members 21 and 21c of the connecting members J10a and J10c also have desirable directions. That is, when the cross-sectional shapes of these beam members 21 and 21c have a strong axis direction and a weak axis direction that is perpendicular to the strong axis direction and has a second moment of section smaller than the strong axis direction. Preferably, the strong axis direction of the beam members 21 and 21c is preferably along the vertical direction. In the example of FIG. 5, since the H-section steel is used for the beam members 21 and 21c, the beam members 21 and 21c are arranged so that the web surface 21ws of the H-section steel extends along the vertical direction.

And if it does in this way, the rigidity and intensity | strength of the beam materials 21 and 21c can be raised to a perpendicular direction, and, thereby, the rigidity and intensity | strength of frame member F10 and connection member J10a, J10c are indirectly constructed. As a result, the horizontal rigidity and the horizontal strength of the outer frame 10 can be improved as a whole. As a result, the cross-sectional size of the beam members 21 and 21c can be reduced by an amount corresponding to the improvement in rigidity and strength. As a result, through the reduction of the protruding amount of the beam members 21 and 21c into the internal space SP10 of the outer frame 10, The internal space SP10 can be expanded and the rectangular opening OP according to the Feelendale format can be expanded.
As in the case of the column member 11, the beam members 21 and 21c are not limited to H-shaped steel, but may be groove-shaped steel or steel pipes having a rectangular cross section.

  As described above with reference to FIG. 2, a plurality of steel beam members 50, 50... Are bridged over the outer frame 10 across the internal space SP10. Above that, a plurality of corrugated deck plates 62, 62... Are provided and supported by the beam members 50, 50. Furthermore, concrete (not shown) is placed from above the deck plates 62, 62..., Thereby forming the floor 60 on the second floor.

  As shown in FIG. 2 and FIG. 4A, each beam member 50, 50... Has a short side direction of the building 5 as a bridging direction, and thus a plurality of beam members 50, 50 are arranged in the long side direction of the building 5. … Are arranged side by side intermittently. In addition, since the bridging direction is set to the short side direction of the building 5, bending deformation below the beam member 50 is suppressed, and the cross-sectional size of the beam member 50 can be reduced accordingly. In addition, since the beam member 50 is made of steel in the first place, it has higher strength than the RC structure, and the cross-sectional size can be reduced by that amount. A relatively high ceiling height can be secured. Furthermore, since the plurality of beam members 50 are provided, the support of the weight of the floor portion 60 can be shared by the plurality of beam members 50, 50. That is, it is possible to reduce the load applied to each beam member 50 and reduce the beam length of each beam member 50. This also contributes to securing the above-described high ceiling height. In addition, since the spanning direction of all the beam members 50 is parallel to the short side direction which is one direction, long indoor equipment such as an air conditioning duct is arranged in a space between the beam members 50 and 50. The installation of the long indoor equipment is excellent.

  The beam members 50, 50... Function as floor beams that support the floor portion 60 on the second floor as described above, so that each beam member 50 is substantially intermediate in the longitudinal direction of the column member 11 at the beam end. It connects with a site | part and is supported by the pillar materials 11 and 11 by this. 8A and 8B are explanatory diagrams of this connection structure. FIG. 8A shows a plan sectional view, and FIG. 8B shows a longitudinal sectional view. 8A is also a cross-sectional view taken along line AA in FIG. 8B, and FIG. 8B is also a cross-sectional view taken along line BB in FIG. 8A.

  As shown in FIGS. 8A and 8B, in this example, the beam member 50 is also H-shaped steel. From the viewpoint of suppressing downward deflection, the strong axis direction of the beam member 50 is oriented in the vertical direction. That is, the flanges 50f and 50f are positioned at the upper and lower portions of the beam member 50, respectively, and the web 50w is positioned between the flanges 50f and 50f.

  Here, the beam end of the beam member 50 is pin-bonded to the web 11 w of the column member 11. Specifically, from the web 11w of the column member 11, a gusset plate 15 rigidly joined to the web 11w extends toward the beam member 50. The gusset plate 15 and the web 50w of the beam member 50 are mutually connected. In a state of being overlapped on the side surfaces, they are connected via a connecting member 17 such as a horizontal pin or a bolt. Here, the pin joint is a joint structure that allows relative rotation at the coupling position and restricts other relative movements to be impossible. Therefore, only the own weight of the beam member 50 and the floor 60 acts on the beam end of the beam member 50, and the input of the bending moment is reduced. Therefore, the beam at the beam end of the beam member 50 is reduced by the reduced amount. The reason can be reduced. Therefore, in the example of FIG. 8B, the lower part of the beam end of the beam member 50 is cut out in a step shape, and the beam h50e at the beam end is made smaller than the beam h50c of the stationary part such as the central part of the beam member 50. . And it becomes easy to hide the beam end of the beam member 50 in the outer periphery frame 10, and as a result, the said beam end can be made hard to see from the outdoors, and the design property of the external appearance of the building 5 is made favorable. .

More specifically, in this example, the beam member 21 located in the middle of the height direction among the beam members 21, 21... Of the outer frame 10 is the beam member 21 closest to the floor surface height on the second floor. The beam member 50 is arranged so that the upper surface 21us of the beam member 21 and the upper surface 50us of the beam member 50 are substantially aligned in the height direction. In this example, the beam h50c of the beam member 50 is larger than the beam h21 of the beam 21 of the outer frame 10. Therefore, the beam member 50 protrudes downward from the beam member 21 at the beam end by the amount of the beam h50c, which makes it easier to see the beam end of the beam member 50 from the outside. As a result, the building 5 The design of the external appearance is impaired. However, regarding this point, if the beam h50e of the beam member 50 is reduced at the beam end as described above, the beam h50e at the beam end can be substantially aligned with the beam h21 of the beam member 21. As a result, the beam end of the beam member 50 can be hidden from the shadows of the beam member 21 and the column member 11 of the outer frame 10 so as to be difficult to see from the outside.
If the beam end of the beam member 50 is cut out in this way, the space formed below the cutout portion 50k can also be used as an installation space for indoor equipment such as a curtain box and a blind box. The notch shape of the notch 50k at the beam end is not limited to the step shape of FIG. 8B, but may be a taper shape in which the beam h50e gradually decreases toward the beam end (FIG. 9B). Other shapes may be used.
Preferably, for the purpose of reinforcing the gusset plate 15 from above and below, a pair of upper and lower horizontal plates (not shown) are provided on the web 11w of the column member 11, and the gusset plate 15 is rigidly joined while being sandwiched from above and below by these horizontal plates. May be.

  In the above example, the beam members 50 are connected to the column member 11 because the beam members 50, 50... Are arranged in accordance with the column divisions of the column members 11, 11,. It is not limited. For example, when the arrangement position of the column member 11 and the arrangement position of the beam member 50 are different due to various circumstances, the beam member 50 may be coupled to the beam member 21 of the outer frame 10. 9A and 9B are explanatory diagrams of the connection structure, FIG. 9A shows a plan sectional view, and FIG. 9B shows a BB sectional view in FIG. 9A. In this example, the gusset plate 15 extends from the web 21 w of the beam member 21 of the outer frame 10 toward the beam member 50. The gusset plate 15 and the web 50w of the beam member 50 are connected to each other via the connecting member 17 such as a horizontal pin or a bolt in a state where they overlap each other. Pin-bonded to the beam member 21 of the frame 10.

  By the way, depending on the case, you may incorporate the damping member 80 and the earthquake-resistant member 85 in the frame member F10. Here, the damping member 80 is a member that absorbs vibration energy of the outer frame 10 such as an oil damper or a friction damper, and the damping member 80 is, for example, as shown in FIG. Each rectangular opening OP of the frame member F10 is provided so as to be bridged in the diagonal direction. The seismic member 85 is a member that suppresses deformation of the outer frame 10 such as a brace or a steel plate seismic wall 85, and the former brace has a diagonal for each rectangular opening OP of the frame member F10. In the latter steel plate seismic wall 85 provided in the direction, as shown in FIG. 10B, for each opening OP that the frame member F10 has, several openings OP, OP. It is provided so as to cover the openings OP, OP.

  And if such a damping member 80 and the earthquake-resistant member 85 are incorporated in the frame member F10, it is not necessary to separately provide the damping member 80 and the earthquake-resistant member 85 in the internal space SP10 of the outer frame 10. As a result, The internal space SP10 can be secured widely. Further, if the vibration damping member 80 and the earthquake-resistant member 85 are previously incorporated and mounted in the frame member F10 in a factory or the like, the work load at the construction site can be reduced.

Here, the construction method of this building 5 is demonstrated with reference to FIG. 3A thru | or FIG. 4B.
First, the frame member F10 is manufactured by assembling the column member 11 and the beam member 21 in a factory or the like equipped with a dedicated processing device or the like (frame member manufacturing step). In addition, the connecting member J10 (J10a, J10c) and the beam member 50 are also manufactured. In addition, in the frame member F10, the damping member 80 and the earthquake-resistant member 85 are also incorporated as needed. And these frame members F10 etc. are conveyed to the construction site which is the construction place of the building 5. FIG.

  Next, a plurality of frame members F10, F10,... Are arranged on the upper surface of a concrete foundation 3 (not shown in FIGS. 3A to 4B) provided on the ground G at the construction site (frame member arrangement step). At this time, each frame member F10 is intermittently disposed along the outer periphery of the building 5 to be constructed, that is, along the outer periphery direction of the building. And the lower end part of the column material 11 of each frame member F10 is rigidly joined to the steel material of the foundation 3 at the same arrangement position at each arrangement position, whereby each frame member F10 is connected and integrated with the foundation 3.

  Then, as shown in FIG. 3B, the frame members F10 and F10 adjacent in the building outer peripheral direction are sequentially connected by the connecting members J10 (J10a and J10c) (frame member connecting step). Thereby, the cyclic | annular outer periphery frame 10 continued over the perimeter of a building outer peripheral direction is completed.

  Next, as shown in FIG. 4A, a plurality of beam members 50, 50... Are bridged to the outer frame 10 with the short side direction of the outer frame 10 being the bridging direction (beam member bridging step). Specifically, one beam member 50 is connected to each column member 11 located on the long side of the outer frame 10 by pin joining to support each beam member 50 at both ends. 4B, after placing a plurality of steel deck plates 62, 62... Above the beam members 50, 50..., Concrete not shown is placed on the deck plates 62, 62. Then, the second floor 60 of the building 5 is formed (floor forming step).

  Then, finally, the upper part of the outer frame 10 is covered with a roof material (not shown), and outer walls and window frames (not shown) are appropriately installed on the sides of the outer frame 10 to complete the building 5 as described above. .

  Incidentally, in the above-described first embodiment, since the building 5 is a two-story building, the single column H of the frame member F10 in FIG. Using shape steel, the frame member F10 was formed in a size corresponding to the second floor of the building 5. However, the size of the frame member F10 is not limited to this, for example, the first floor. Also good. In that case, as shown on the left side of FIG. 11, as the frame members F10a and F10b, for example, two types of a frame member F10a for the first floor and a frame member F10b for the second floor are prepared. Both of the frame members F10a, F10b have a pair of column members 11, 11 having a length corresponding to the height of the first floor, and a plurality of beam members 21, 21 connecting the pair of column members 11, 11 to each other. The first-floor frame member F10a has beam members 21 at the upper and lower ends of the column member 11, whereas the second-floor frame member F10b The beam member 21 at the lower end of the member 11 is omitted. This is due to the following reason. At the time of construction of the outer frame 10, the top surface 11 ss of the upper end of the column member 11 of the first floor frame member F 10 a and the second floor frame member are stacked in order to stack the second floor frame member F 10 b above the first floor frame member F 10 a. The bottom edge 11ss of the pillar material 11 of F10b is abutted and rigidly joined. At this time, the beam material 21 at the upper end of the first floor frame member F10a is connected to the lower end of the second floor frame member F10b. This is because it also serves as the beam material 21 of the part. However, the present invention is not limited to this. For example, the same structure as the first floor frame member F10a may be used not only on the first floor but also on the second floor, and conversely, the second floor frame. The member F10b may be used not only on the second floor but also on the first floor.

  Further, in the example on the left side of FIG. 11, the height position of the small edge surface 11ss at the upper end of the column member 11 is set to the uppermost beam member in the vicinity thereof for both the first and second frame members F10a and F10b. However, the present invention is not limited to this. As shown on the right side of FIG. 11, the upper end portion of the column member 11 of the frame member F10a for the first floor is connected to the beam member 21. It may be slightly protruded upward in the vertical direction from the upper surface 21us, and the upper end portion of the column member 11 of the frame member F10b for the second floor may be similarly protruded upward.

  Further, the width dimension of the frame member F10 may be a multiple of the dimensions of the first embodiment described above. FIG. 12 illustrates the case of double and triple as an example of multiple times. However, the formation of the frame members F10c and F10d having multiple widths is formed on the side of the frame member F10. This is done by providing a widening part P10 that includes a single column member 11 and a plurality of beam members 21, 21,... For example, in the case of double, one widening part P10 may be additionally provided on the side of the frame member F10, and in the case of triple, two widening parts P10 are provided on the side of the frame member F10. Just add them together. And according to this structure, since arrangement pitch of pillar material 11 of widened frame members F10c and F10d becomes the same as arrangement pitch of pillar material 11 of frame member F10 of a 1st embodiment, frame members F10c, The rigidity and strength of F10d can be maintained at the same level as that of the frame member F10. Incidentally, as can be seen with reference to FIG. 12, the outer appearance of the frame members F10c and F10d has a lattice shape rather than a ladder shape, but each of the frame members F10c and F10d has a rectangular opening OP. Therefore, it is a kind of feelerdale type frame member.

  Further, when the building 5 to be constructed is a three-story or four-story building, the column member 11 of the frame members F10, F10c, F10d has a length corresponding to the height of the third or fourth floor. By using the actual pillar material 11, the frame members F10, F10c, and F10d may be formed in a size corresponding to the third floor or the fourth floor of the building 5.

=== Second Embodiment ===
FIG. 13 is a schematic perspective view of a building 5 ′ of the second embodiment. In FIG. 13, a part of the structure of the building 5 ′ such as an outer wall material or a roof material is omitted.

  The building 5 of the first embodiment described above is a two-story building, but the building 5 'of the second embodiment is a three-story building, which is mainly different in this respect and is otherwise substantially the same. . Therefore, in the following description, differences are mainly described, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  This building 5 'has an outer frame 10' having a height of three floors. The outer frame 10 'basically includes a frame member F10b having a height of one floor above each frame member F10 of the outer frame 10 having a height of two floors according to the first embodiment. Of the plurality of stacked frame members F10b, F10b..., The frame members F10b and F10b adjacent to each other in the building outer peripheral direction are connected to each other by connecting members J10a and J10c ′.

  Here, the “frame member F10b having the height of one floor” to be stacked includes, for example, the frame member F10b described above with reference to FIG. The omitted frame member F10b is used. For the connecting members J10a and J10c ′ for connecting the frame members F10b and F10b, a connecting member J10c ′ is prepared for arranging the corner 5c ′ of the building 5 ′, and each side of the building 5 ′ is arranged. For this purpose, a connecting member J10a is prepared. As the former connecting member J10c 'for arranging the corner portion 5c', the connecting member J10c of the first embodiment is simply changed to the height of the first floor, and the latter connecting member for arranging each side. As J10a, the beam material 21 is used as in the first embodiment.

  In the inner space SP10 ′ of the outer frame 10 ′, a floor 60 is provided for each floor, that is, a floor 60 (2F) on the second floor and a floor 60 (3F) on the third floor are provided. . Each floor portion 60 is supported by a beam member 50 (not shown in FIG. 13) spanned directly below the floor portion 60. The structures of the floor 60 and the beam member 50 are the same as those described in the first embodiment. Further, a roof material (not shown) is provided on the upper portion of the outer frame 10 ', and an outer wall material, a window frame, etc. (not shown) are provided on the side of the outer frame 10'.

  Such a three-story building 5 'is constructed as follows. FIG. 14A to FIG. 15B are schematic diagrams for explaining this construction procedure, and in each figure, a side view is shown on the left side and a top view is shown on the right side.

  First, in the same procedure as in the first embodiment, the outer frame 10 having a height of two floors is formed on the foundation 3 of the ground G, and the beam members 50, 50... Are installed across the inner space SP10. The second floor part 60 (2F) is formed on the beam members 50, 50. Thereby, the building 5 ′ is constructed to the state shown in FIG. 14A (FIG. 4B). In some cases, the floor 60 on the second floor may not be formed at this point, and may be kept until the beam member 50 is installed. In that case, the forming operation of the floor portion 60 (2F) may be performed at the same timing as the formation of the floor portion 60 (3F) on the third floor, or, at the end, the outer frame 10 having the height of the third floor. It may be done after completion of '. Incidentally, at this time, the reason why at least only the beam members 50, 50... Are installed on the outer frame 10 having the height of the second floor, which is in the middle of formation, is to prevent the outer frame 10 from collapsing.

  Next, as shown in FIG. 14B, a plurality of beam members 50, 50... Are bridged over the upper end portion of the outer frame 10 having the height of the second floor (beam member bridging step). These beam members 50, 50... Serve as floor beams that support the third-floor floor 60 formed later. In the installation of the beam member 50, both ends of the beam member 50 are pin-joined to the corresponding column members 11 and 11 of the outer frame 10 in the same manner as the beam member 50 on the second floor. Each beam member 50 is in a state where both ends are supported by the outer frame 10. Note that the joint structure of this pin joint is the same as that of the beam member 50 of the first embodiment described above.

  14C, after placing a plurality of deck plates 62, 62... Above the beam members 50, 50..., Concrete (not shown) is placed on the deck plates 62, 62. A floor 60 (3F) on the third floor of the building 5 ′ is formed. As described above, if the second-floor floor 60 (2F) is not yet formed at this time, the second-floor floor 60 (2F) and the third-floor floor 60 (3F) are at this timing. Both may be formed, or the formation operation of the third floor portion 60 (2F) is performed last, following the last formation operation of the second floor portion 60 (2F). In some cases, it may not be performed here.

  Then, as shown to FIG. 15A, the frame member F10b of the height of the 1st floor is each piled up on each frame member F10 of the outer periphery frame 10 of the height of 2 floors (frame member stacking process). At this time, the small edge surface of the lower end of the column member 11 of the frame member F10b having the height of one floor to be stacked is rigidly joined to the small edge surface of the upper end of the column member 11 of each frame member F10 of the outer frame 10. . Then, such a stacking operation of the frame members F10b is performed on all the frame members F10 included in the outer frame 10, so that the frame member F10b having a height of one floor is disposed above the outer frame 10. , F10b... Are intermittently arranged in the outer periphery direction of the building.

  Then, as shown in FIG. 15B, the frame members F10b and F10b adjacent to each other in the building outer peripheral direction are sequentially connected by the connecting members J10a and J10c ′ (frame member connecting step). An annular outer frame 10 'is completed.

  Finally, the upper part of the outer frame 10 'is covered with a roof material (not shown), and appropriate outer wall materials, window frames, etc. (not shown) are installed on the sides of the outer frame 10'. Complete. If the second and third floors 60 (2F) and 60 (3F) are not yet formed at this time, the floors 60 (2F) and 60 (3F) are also formed at this time. Do.

  By the way, in the second embodiment described above, the building 5 ′ has three floors, but the number of floors of the building 5 ′ may be larger. And as an example of the construction method in that case, with respect to the upper end portion of the outer frame 10 ′ formed up to the middle floor, the above-mentioned “beam member spanning step”, “frame member stacking step” and “frame member connection” It is mentioned that the “step” is repeated until the outer frame 10 ′ reaches the target floor height. At that time, the frame member F10b to be stacked is not limited to the above-mentioned “frame member F10b having a height of one floor”, but is a frame member F10 having a height of two floors or a height of three floors. A frame member or the like may be used as appropriate, that is, the size of the frame member may be selected at any time according to the construction situation.

=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof. For example, the following modifications are possible.

  In the above-described embodiment, the frame members F10 and F10 are connected to each other by the connecting member J10 such as the beam member 21, but in some cases, the connecting member J10 may not be used. That is, as shown in the side view of the outer frame 10 ″ in FIG. 16, the frame members F10 and F10 are brought into contact with each other without providing a space between the frame members F10 and F10 adjacent to each other in the building outer peripheral direction. The frame members F10 and F10 may be directly rigidly joined. And according to this structure, the connection member J10 can be abbreviate | omitted and the kind of component of outer periphery frame 10 '' can be reduced. However, in the case of this configuration, the column member 11 of the frame member F10 and the column member 11 of the adjacent frame member F10 are arranged adjacent to each other without a gap, so that the above-described implementation is performed. The ratio of the area occupied by the opening OP in the outer peripheral surface of the outer frame 10 '' is lower than that of the form. For this reason, when the building 5 or 5 'is open, the frame members F10 and F10 are connected by the connecting member J10 such as the beam member 21 as in the first and second embodiments described above. Is preferred.

  In the above-described embodiment, the partition wall that divides the floor of each floor into several rooms is not illustrated, but the present invention is not limited to this, and a partition wall may be provided.

  In the above-described embodiment, the case where the buildings 5 and 5 ′ are two or more stories is illustrated, but the present invention is not limited to this, and a one-story one-storied house may be used. In that case, the frame member F10a or the frame member F10b of FIG. 11 is used. That is, the frame members F10a and F10b in which the length of the column member 11 is set to a length corresponding to the height of the first floor are used.
