In the above-mentioned basic structure, the rising piece to which the end of the rising member is joined receives the rising member on the side surface extending in the vertical direction. In this way, since the rising piece receives the rising member on its side surface, it is difficult to vertically align the rising member with the rising member. Furthermore, even if the upright piece is arranged vertically with high precision, the vertical position of the upright member may shift due to rattling of the bolt or the like. Therefore, it is necessary to adjust the height using a level adjuster that supports the rising member from below. However, when a level adjuster is used, the height adjustment points are dispersed at multiple points on the rising piece and the level adjuster, so the reference becomes ambiguous and it may be difficult to ensure accuracy.

Note that the locations corresponding to the corners of each section are locations where the ends of the pair of rising members 1 are close to each other. Such a location will be referred to as a node 15 in the following description.

Each division E1, E2, E3, E4 is divided by 12 standing members 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H, 1K, 1L, 1N, 1M. In the following description, if the rising members 1A to 1M are to be explained without distinguishing them, they will simply be referred to as "rising members 1."

Note that the rising members 1K and 1L also constitute the negative sides of the sections E3 and E4 in the Y-axis direction. The negative end of the rising member 1K in the X-axis direction forms a node 15 between the rising members 1E and 1F. The end of the rising member 1L on the positive side in the X-axis direction forms a node 15 between the rising members 1G and 1H. The rising members 1N and 1M forming the positive sides of the sections E1 and E3 in the X-axis direction extend in the Y-axis direction, and form a node 15 by lining up so that their ends face each other. ing. Note that the rising members 1N and 1M also constitute the negative side sides of the sections E2 and E4 in the X-axis direction.

The positive end of the rising member 1M in the Y-axis direction forms a node 15 between the rising members 1C and 1D. Further, the positive end of the rising member 1N in the Y-axis direction and the negative end of the rising member 1M in the Y-axis direction form a node 15 between the rising members 1K and 1L.

Among the above-mentioned nodes 15, the node 15 where the rising members 1 join from two directions is referred to as a "node 15A." Specifically, the node 15 between the rising members 1A and 1E, the node 15 between the rising members 1B and 1G, the node 15 between the rising members 1C and 1F, and the node 15 between the rising members 1D and 1H are "node 15A". Applies to. Among the above-mentioned nodes 15, the node 15 where the rising members 1 join from three directions is referred to as a "node 15B." Specifically, node 15 between rising members 1A, 1B, and 1N, node 15 between rising members 1C, 1D, and 1M, node 15 between rising members 1E, 1F, and 1K, and node 15 between rising members 1G, 1H, and 1L. Node 15 corresponds to "node 15B". Among the above-mentioned nodes 15, the node 15 where the rising members 1 join from four directions is referred to as a "node 15C." Specifically, the node 15 between the rising members 1K, 1L, 1N, and 1M corresponds to the "node 15C."

At a node 15A where the rising members 1 join from two directions, the two rising members 1 are connected by one connecting member 2 and one connecting member 4. At a node 15B where the rising members 1 join from three directions, the three rising members 1 are connected by one connecting member 3 and two connecting members 4. At a node 15C where the rising members 1 join from four directions, the four rising members 1 are connected by the four connecting members 4. Note that the specific configuration of the connecting members 2, 3, and 4 will be described later together with the connecting structures 50A, 50B, and 50C at the respective nodes 15A, 15B, and 15C.

A node steel pipe 6 is arranged at each node 15A, 15B, 15C. The nodal steel pipe 6 is a rectangular annular steel pipe. The nodal steel pipe 6 constitutes a closing member surrounded by walls on all sides. The closed spaces inside the nodal steel pipes 6 arranged at each of the nodes 15A, 15B, and 15C are filled with concrete, thereby forming a concrete-filled portion 9. When a wooden structure is constructed above the foundation structure 100, pillars are placed at locations corresponding to the nodes 15A, 15B, and 15C. Therefore, the nodal steel pipe 6 and the concrete filling section 9 can support the load from the column section. Further, the steel frame foundation 10 is supported from below by the height adjusting member 7 at each node 15A, 15B, 15C.

Next, the rising member 1 will be described in detail with reference to FIGS. 5 and 6. FIG. 5 is a perspective view showing how the rising member 1 is installed. FIG. 6 is an enlarged view showing a location corresponding to node 15B shown in FIG.

As shown in FIGS. 5 and 6, the rising member 1 is a member that rises upward in the basic structure 100 and extends in the horizontal direction (either the X-axis direction or the Y-axis direction). The rising member 1 includes a square steel pipe 20, a fixing portion 21, and an anchor bolt 22. Note that when describing the structure of the upright member 1, the terms "longitudinal direction" and "width direction" may be used. The longitudinal direction is the direction in which the upright member 1 extends. The width direction is a direction perpendicular to the longitudinal direction and the up-down direction. For example, in the rising member 1K, the X-axis direction corresponds to the longitudinal direction, and the Y-axis direction corresponds to the width direction. In the rising member 1F, the Y-axis direction corresponds to the longitudinal direction, and the X-axis direction corresponds to the width direction.

The square steel pipe 20 is a cylindrical member made of steel and has a rectangular cross section. The square steel pipe 20 functions as a steel beam extending horizontally between the pair of height adjustment members 7. The square steel pipe 20 has a bottom wall portion 23 and a top wall portion 24 that face each other in parallel in the vertical direction. Moreover, the square steel pipe 20 has a pair of side walls 26 that connect both ends of the bottom wall 23 and the top wall 24 in the width direction. The pair of side wall portions 26 face each other in parallel in the width direction. In this embodiment, the square steel pipe 20 has a rectangular cross-section that extends in the vertical direction. Therefore, the vertical dimension of the side wall section 26 is larger than the width dimension of the bottom wall section 23 and the upper wall section 24. However, the cross-sectional shape of the square steel pipe 20 is not limited, and may be square in cross-section.

As shown in FIG. 6, the rising member 1 is integrated with the concrete portion 8 (indicated by a phantom line in FIG. 6) at the bottom surface 20a of the square steel pipe 20. The bottom surface 20a of the square steel pipe 20 is the lower surface of the bottom wall portion 23. The upper surface of the concrete portion 8 is formed at least at a position where it contacts the bottom surface 20a. That is, when the formwork is filled with concrete, the concrete contacts the square steel pipe 20 at least at the bottom surface 20a. By solidifying the concrete in this state, the square steel pipe 20 is fixed to the concrete portion 8 at the bottom surface 20a. Thereby, the square steel pipe 20 is integrated with the concrete portion 8 at the bottom surface 20a.

The fixing portion 21 is a member that protrudes downward from the bottom wall portion 23 of the square steel pipe 20. The fixing section 21 protrudes downward from the lower surface of the bottom wall section 23, that is, the bottom surface 20a. A plurality of fixing sections 21 are provided on the bottom wall section 23 so as to be lined up at a predetermined pitch along the longitudinal direction. The fixing section 21 is fixed to the concrete section 8 and thereby becomes integrated with the concrete section 8 . The fixing part 21 has a shaft part 21a extending downward from the bottom wall part 23, and a head part 21b having a diameter larger than that of the shaft part 21a at the lower end of the shaft part 21a. When the concrete part 8 is formed by solidifying the concrete, the fixing part 21 is buried in the concrete part 8 and becomes fixed. Since the head portion 21b is surrounded by concrete in all directions, the supporting force of the concrete against the upward pulling force is greater than that of the shaft portion 21a. Note that the lower end of the fixing section 21 is arranged at a higher position than the sacrificial concrete 16 (see FIG. 11).

Anchor bolt 22 is a member that projects upward from upper wall portion 24 of square steel pipe 20 . Anchor bolt 22 projects upward from the upper surface of upper wall portion 24 . A plurality of anchor bolts 22 are provided on the upper wall portion 24 so as to be lined up at a predetermined pitch along the longitudinal direction. The pitch of the anchor bolts 22 is larger than the pitch of the fixing portions 21. The anchor bolt 22 is connected to a wooden foundation of a wooden building placed above the foundation structure 100.

Next, the height adjustment member 7 will be described in detail with reference to FIGS. 3, 4, and 6. FIG. 3 is an enlarged view of the height adjustment member 7. FIG. 4 is a perspective view of the height adjustment member 7 viewed from below. As shown in FIG. 6, the height adjusting member 7 is a member that adjusts the height of the rising member 1. As shown in FIG. The height adjustment member 7 includes a base member 30 and foot members 31.

The base member 30 is a separate member from the rising member 1, and is a member having a mounting surface 32 on which the rising member 1 is placed. The base member 30 is a rectangular plate-like member. The base member 30 has tapped holes 33 on each of the four edges. The leg member 31 is inserted through the tap hole 33 and is screwed into the leg member 31 . Note that the shape of the base member 30 is not particularly limited. The upper surface of the base member 30 functions as a mounting surface 32. The mounting surface 32 constitutes a plane. Therefore, the mounting surface 32 can come into surface contact with the bottom surface 20a of the square steel pipe 20 of the standing member 1 placed thereon. The base member 30 is formed with a penetrating portion 34 in which the concrete portion 8 is disposed. The penetrating portion 34 is arranged approximately at the center of the base member 30. Although the penetrating portion 34 is constituted by a circular through hole, the shape, size, and number of the penetrating portion 34 are not particularly limited.

The leg member 31 is a member separate from the stand-up member 1, and is a member extending in the vertical direction from the base member 30. The leg member 31 is constituted by a bar member having a spiral bolt groove formed on its outer circumferential surface. One height adjustment member 7 has four leg members 31. Each foot member 31 is screwed into four tap holes 33 of the base member 30, respectively. The lower end of the leg member 31 is installed on the upper surface of the concrete 16. When the foot member 31 is rotated with respect to the base member 30, the amount of protrusion of the foot member 31 extending downward from the base member 30 changes. Therefore, the vertical position of the mounting surface 32 of the base member 30 can be adjusted along the leg member 31. Thereby, the height of the mounting surface 32 of the base member 30 from the upper surface of the sacrificial concrete 16 can be adjusted. The leg member 31 is in a state where it is buried in the concrete part 8. Therefore, the leg member 31 is fixed to the concrete part 8 and integrated with the concrete part 8. As described above, the height adjustment member 7 is integrated with the concrete portion 8.

As shown in FIG. 6, the end portion 20c of the square steel pipe 20 of the rising member 1 is placed on the placement surface 32 of the height adjusting member 7. The end 20c of the square steel pipe 20 is placed near the edge of the base member 30. At this time, the bottom surface 20a of the square steel pipe 20 near the end 20c is in surface contact with the mounting surface 32, and is supported by the mounting surface 32.

A portion of the leg member 31 that protrudes upward from the mounting surface 32 is inserted into a through hole in the bottom wall portion 23 of the square steel pipe 20. The bottom wall portion 23 of the square steel pipe 20 is fixed to the base member 30 by being fastened with a nut 36 screwed onto the leg member 31. Note that the square steel pipe 20 is open at the end 20c. Therefore, the operator can reach the leg member 31 and the nut 36 through the opening of the end portion 20c.

Next, with reference to FIG. 6, the positional relationship of the square steel pipe 20 of the rising member 1 in a state fixed to the height adjusting member 7 will be described. Here, the positional relationship between the rising member 1K and the rising member 1F will be explained, but the same applies to the positional relationship between the other rising members 1.

The square steel pipe 20 of the rising member 1K extends from the positive side to the negative side in the X-axis direction with respect to the base member 30, and is placed on the edge of the base member 30 on the positive side in the X-axis direction. At this time, the end portion 20c of the square steel pipe 20 of the rising member 1K is arranged so as to spread out in parallel to the XZ plane near the positive edge of the base member 30 in the X-axis direction. The end portion 20c of the square steel pipe 20 of the rising member 1K is arranged at a position spaced apart from the center position of the base member 30 in the X-axis direction toward the positive side in the X-axis direction. The square steel pipe 20 of the rising member 1F extends from the positive side to the negative side in the Y-axis direction with respect to the base member 30, and is placed on the edge of the base member 30 on the positive side in the Y-axis direction. At this time, the end portion 20c of the square steel pipe 20 of the rising member 1F is arranged so as to spread out in the vicinity of the positive edge of the base member 30 in the Y-axis direction so as to be parallel to the YZ plane. The end portion 20c of the square steel pipe 20 of the rising member 1F is arranged at a position spaced apart from the center position of the base member 30 in the Y-axis direction toward the positive side in the Y-axis direction.

At this time, the position of the end 20c of the square steel pipe 20 of the rising member 1K in the X-axis direction is the same as the side surface 20b on the inner corner side of the square steel pipe 20 of the neighboring rising member 1F (the side surface 20b closer to the rising member 1K). position, or a position on the positive side of the side surface 20b in the X-axis direction. Furthermore, the position of the end 20c of the square steel pipe 20 of the rising member 1F in the Y-axis direction is the same as the side surface 20b on the inner corner side of the square steel pipe 20 of the neighboring rising member 1K (the side surface 20b closer to the rising member 1F). , or a position on the positive side of the side surface 20b in the Y-axis direction. Due to this arrangement, the edge portion between the end 20c of the rising member 1K and the side surface 20b on the inner corner side and the edge portion between the end portion 20c of the rising member 1F and the side surface 20b on the inner corner side are approximately come into contact with or be in close proximity. Thereby, a space SP is provided between the end 20c of the rising member 1K and the end 20c of the rising member 1F. When viewed from above, the space SP is defined on the positive side in the X-axis direction by the end 20c of the rising member 1K, and on the positive side in the Y-axis direction by the end 20c of the rising member 1F. Note that a rising member 1E is also placed on the height adjustment member 7 shown in FIG. 6 from the negative side in the Y-axis direction (see FIG. 2). Therefore, the space SP is defined on the negative side in the Y-axis direction by the end 20c of the rising member 1E.

As shown in FIG. 2, at a node 15A where the rising members 1 join from two directions, the height adjusting member 7 supports the square steel pipe 20 of each rising member 1 at the two edges of the base member 30. Therefore, the space SP provided at the node 15A is defined by the end portion 20c of each rising member 1 from two directions. At the node 15B where the rising members 1 join from three directions, the height adjusting member 7 supports the square steel pipe 20 of each rising member 1 at the three edges of the base member 30. Therefore, the space SP provided at the node 15B is defined by the end portion 20c of each rising member 1 from three directions. At the node 15C where the rising members 1 join from four directions, the height adjusting member 7 supports the square steel pipe 20 of each rising member 1 at the four edges of the base member 30. Therefore, the space SP provided at the node 15C is defined by the end portions 20c of each rising member 1 from four directions.

Next, the structure of the connecting structure 50A will be explained with reference to FIGS. 7 and 8. 7 and 8 are enlarged views showing the state of the node 15A shown in FIG. 2. Note that FIGS. 7 and 8 show the state before the node steel pipe 6 is inserted into the node 15A. Moreover, FIGS. 7 and 8 show a node 15A between the rising members 1A and 1E. However, the gist of the explanation regarding the node 15A also holds true for the other nodes 15A. As shown in FIGS. 7 and 8, the connection structure 50A includes rising members 1A and 1E, a connection member 2, and a connection member 4.

As described above, a space SP is provided between the ends 20c of the rising member 1 at the node 15A. Here, a space SP is provided between the negative end 20c of the rising member 1A in the X-axis direction and the negative end 20c of the rising member 1E in the Y-axis direction.

Therefore, the joint portion 42 partitions the space SP from the negative side in the X-axis direction.

The connecting member 4 is a member that connects the pair of rising members 1A and 1E. The connecting member 4 is joined to the side surfaces 20b, 20b of the pair of rising members 1A, 1E so as to secure the space SP. The connecting member 2 is joined at the corner 51 to the inner corner side surfaces 20b, 20b of the respective upright members 1A, 1E.

The lower end of the joint portion 44 is arranged at approximately the same position as the bottom surface 20a of the rising member 1E. The upper end of the joint portion 44 is arranged at approximately the same position as the upper surface 20d of the rising member 1E. The positive end of the joint portion 44 in the Y-axis direction is located near the positive end of the base member 30 of the height adjustment member 7 in the Y-axis direction. Therefore, the joint portion 44 is joined to a part of the region near the end portion 20c on the side surface 20b on the inner corner side of the rising member 1E. The negative end of the joint 44 in the Y-axis direction, that is, the corner with the joint 41, is arranged at approximately the same position as the outer corner side side surface 20b of the rising member 1A in the Y-axis direction.

A space SP is provided in between.

The connecting member 3 is a member that connects the pair of rising members 1A and 1B. The connecting member 3 is joined to the side surfaces 20b, 20b of the pair of rising members 1A, 1B so as to secure the space SP. The connecting member 3 is joined to the outer side surfaces 20b, 20b of the steel frame base 10 of the pair of rising members 1A, 1B so as to partition the space SP. The outer side surface 20b of the steel frame foundation 10 is the side surface 20b that becomes the outer peripheral surface of the steel frame foundation 10. Here, the negative side surfaces 20b, 20b of the rising members 1A, 1B in the Y-axis direction correspond to the outer side surfaces 20b, 20b.

The connecting member 3 secures a space SP corresponding to the widthwise dimension of the square steel pipe 20 in the Y-axis direction between the connecting member 3 and the end portion 20c of the rising member 1N.

The upper end of the connecting member 3 is arranged at approximately the same position as the upper surface 20d of the rising members 1A, 1B. The positive end of the connecting member 3 in the X-axis direction is located near the positive end of the base member 30 of the height adjustment member 7 in the X-axis direction. Therefore, the connecting member 3 is joined to a part of the area near the end 20c on the outer side surface 20b of the rising member 1B. The negative end of the connecting member 3 in the X-axis direction is located near the negative end of the base member 30 of the height adjustment member 7 in the X-axis direction. Therefore, the connecting member 3 is joined to a part of the area near the end 20c on the outer side surface 20b of the rising member 1A. A portion of the connecting member 3 between the end 20c of the rising member 1A and the end 20c of the rising member 1B is arranged to face the end 20c of the rising member 1N in the Y-axis direction with a space SP in between. be done. Therefore, the connecting member 3 partitions the space SP from the negative side in the X-axis direction.

Between the rising member 1A and the rising member 1N, a connecting member 4 is joined to the side surfaces 20b, 20b on the inner corner side of the rising members 1A, 1N.

As described above, a space SP is provided between the ends 20c of the rising member 1 at the node 15C. Here, a space SP is provided between each end of the rising members 1K, 1L, 1N, and 1M. At the node 15C, corner portions are formed at four locations by a pair of mutually adjacent upright members 1, so a connecting member 4 is provided at each of the four corner locations.

Next, the nodal steel pipe 6 inserted into the space SP of the nodal point 15 will be described with reference to FIGS. 10 and 11. FIG. 10 is an enlarged view showing the state of the node 15B shown in FIG. FIG. 11 is a view of the insertion of the node steel pipe 6 at the node 15B in FIG. 10, as viewed from the negative side in the Y-axis direction. Note that the structure of the nodal steel pipe 6 is the same at the other nodes 15B, 15A, and 15C.

As shown in FIGS. 10 and 11, the nodal steel pipe 6 is arranged in the space SP. The nodal steel pipe 6 is a steel pipe with a rectangular cross section, and has side wall portions 6a, 6b, 6c, and 6d on all sides. The side wall portion 6a disposed on the negative side in the X-axis direction is disposed so as to face, contact or be close to the end portion 20c of the rising member 1A. The side wall portion 6b disposed on the positive side in the X-axis direction is disposed so as to face, contact or be close to the end portion 20c of the rising member 1B.

Note that the lower end of the nodal steel pipe 6 is placed on the placement surface 32 of the base member 30 of the height adjustment member 7. The upper end portion of the nodal steel pipe 6 is arranged at the same position as the upper surface 20d of the rising members 1A, 1B, and 1N. Thereby, the openings of the ends 20c of the square steel pipes 20 of the rising members 1A, 1B, 1B are closed by the nodal steel pipes 6. In this manner, with the opening of the end portion 20c closed, the space SP is filled with concrete to form the concrete filled portion 9 (see FIG. 1).

Next, a method for constructing the foundation structure 100 will be described with reference to FIG. 12. FIG. 12 is a process diagram showing a method of constructing the foundation structure 100. As shown in FIG. 12, the construction method of the foundation structure 100 includes a reinforcing bar placement process S10, a height adjustment member placement process S20, a height adjustment process S30, a rising member placement process S40, a connection process S50, and a node It includes a steel pipe placement step S60 and a concrete placement step S70. Among these, the method for adjusting the height of the rising member 1 includes a height adjusting member arrangement step S20 and a height adjusting step S30.

First, before the reinforcing bar placement step S10, root cutting (ground surface excavation), splitting, or crushed stone work is performed at the location where the foundation structure 100 is to be constructed, and concrete 16 is poured. The reinforcing bar arrangement step S10 is a step of constructing the reinforcing steel structure 5 by arranging the reinforcing bars 5a and 5b on the waste concrete 16 (see FIG. 3).

The height adjustment member arrangement step S20 is a step of arranging the height adjustment member 7 on the sacrificial concrete 16. The height adjusting member 7 is installed so that the lower end of the leg member 31 is placed on the sacrificial concrete 16 (see FIG. 3). A plurality of height adjustment members 7 are arranged at positions corresponding to the nodes 15 (see FIG. 2).

The height adjustment step S30 is a step of adjusting the height of the mounting surface 32 of the base member 30. The height of the mounting surface 32 is adjusted by screwing or loosening the foot members 31 into the tapped holes 33. The height adjustment is performed on the mounting surfaces 32 of all the height adjustment members 7 installed on the waste concrete 16. Here, using the placement surface 32 of one height adjustment member 7 as a reference, the height of the placement surface 32 of the other height adjustment member 7 is adjusted in accordance with the level of the reference placement surface 32. .

The rising member arrangement step S40 is a step of arranging the rising member 1 on the mounting surface 32 of each height adjustment member 7. The rising member 1 is installed so as to span between the pair of height adjusting members 7 (see FIG. 5). At this time, a space SP is provided between the ends 20c of the pair of rising members 1. When the alignment of the rising member 1 with respect to the height adjusting member 7 is completed, it is fixed to the height adjusting member 7.

The connection step S50 is a step of connecting the respective rising members 1 with each other using the connection members 2, 3, and 4. Each connecting member 2, 3, 4 connects the side surfaces 20b, 20b of a pair of rising members 1.

The nodal steel pipe placement process S60 is a process of arranging the nodal steel pipes 6 in the spaces SP of each node 15. The nodal steel pipe 6 is inserted into the space SP from above (see FIG. 11). The inserted nodal steel pipe 6 is fixed to the connecting members 2 and 3.

The concrete placing step S70 is a step of forming the concrete portion 8 by placing concrete on the waste concrete 16. By pouring concrete, the rising member 1, height adjusting member 7, and reinforcing steel structure 5 are integrated with the concrete portion 8. At this time, at each node 15, a concrete filled portion 9 is formed by filling the node steel pipe 6 with concrete. Through the above steps, the basic structure 100 is completed.

As described above, the rising member 1 is a rising member 1 that rises upward in the basic structure 100 and extends in the horizontal direction, and includes the square steel pipe 20.

For example, if a steel material with an open cross section, such as channel steel, H-beam steel, or I-beam steel, is used as the rising member, the stiffness of the rising member will be low, so it may bend between nodes 15 and 15. There is sex. Therefore, the construction work may become complicated, such as requiring a reinforcing structure such as reinforcing metal fittings to reinforce the standing member between nodes 15 and increasing the number of level adjustment points. . As described above, when the number of reinforcement structures and level adjustment points increases, the number of bolt connections and the like increases when looking at the entire foundation structure 100, which takes time and effort to construct. On the other hand, the standing member 1 of this embodiment includes a square steel pipe 20. The square steel pipe 20 has higher rigidity than a steel material with an open cross section. Therefore, when the square steel pipe 20 is used as a rising member of the foundation structure 100, it is possible to reduce the number of reinforcement structures and level adjustment locations. Specifically, even if one square steel pipe 20 is bridged between nodes 15 without reinforcing it with reinforcing metal fittings or the like, the rising member 1 will not be able to bridge between the nodes 15 and 15. It can maintain a straight state without bending. As described above, the workability for constructing the foundation structure 100 can be improved.

The rising member 1 includes a fixing portion 21 that protrudes from the square steel pipe 20 and is fixed to the concrete portion 8 to be integrated with the concrete portion. In this case, the rising member 1 can be firmly fixed to the concrete part 8. In this way, when the rising member 1 is firmly fixed to the concrete part 8, a part of the load acting on the rising member 1 can be dispersed also to the concrete part 8. For example, when the upright member 1 receives a load due to vibrations of the building above due to an earthquake, etc., by dispersing the load to the concrete portion 8, deflection of the upright member 1 can be suppressed.

The foundation structure 100 includes the above-described rising member 1 and a concrete portion 8 that is integrated with the rising member 1. By including the above-mentioned rising member 1, this basic structure 100 can obtain the same actions and effects as the rising member 1.

In the foundation structure 100, the rising member 1 is integrated with the concrete portion 8 at the bottom surface 20a of the square steel pipe 20. In this case, the rising member 1 has a structure that stands up from the upper surface of the concrete portion 8. Thereby, the square steel pipe 20 can be used as a base on which a wooden base or the like is placed.

In the foundation structure 100, the square steel pipe 20 integrated with the concrete part 8 may be in a hollow state. In this case, since the square steel pipe 20 is not filled with concrete, the amount of concrete can be reduced. For example, when constructing a rising part of a foundation structure by assembling reinforcing bars, constructing a formwork, and pouring concrete, concrete is required to cover almost the entire rising part. Furthermore, it takes time and effort to assemble reinforcing bars and large formwork. On the other hand, by using the stand-up member 1 having the square steel pipe 20, compared to the case where reinforcing bars and formwork are assembled, construction time and effort can be reduced, and the amount of concrete can also be reduced.

The construction method of the foundation structure 100 includes a step of installing a rising member 1 including a square steel pipe 20 (rising member arrangement step S40), and a step of forming a concrete portion 8 to be integrated with the rising member 1 (concrete placing step S70). and. According to this construction method of the foundation structure 100, by using the rising member 1 including the square steel pipe 20, the same operation and effect as the above-mentioned rising member 1 can be obtained.

Further, the height adjusting member 7 is a height adjusting member 7 that adjusts the height of the rising member 1 that rises upward and extends in the horizontal direction in the basic structure 100, and is a separate member from the rising member 1. , a base member 30 having a mounting surface 32 on which the rising member 1 is placed, and a foot member 31 that is a separate member from the rising member 1 and extends in the vertical direction from the base member 30. The vertical position of the placing surface 32 can be adjusted along the leg member 31.

For example, as a comparative example, there is a structure in which the end of a rising member is joined to the side surface of a steel tubular rising piece in a butted state (for example, a structure as disclosed in Japanese Patent Application Laid-Open No. 2016-887). The height of such a rising piece is adjusted by a level adjustment bolt extending downward from the rising piece. When attaching the rising member to the rising piece, a level adjustment tool is placed on the reinforcing bars below the steel frame unit, and the bottom surface of the rising member is supported by the level adjustment tool. After installation, the level adjuster is removed. The rising piece to which the end portion of the rising member is joined receives the rising member on the side surface extending in the vertical direction. In this way, since the rising piece receives the rising member on its side surface, it is difficult to vertically align the rising member with the rising member. Furthermore, even if the upright piece is arranged vertically with high precision, the vertical position of the upright member may shift due to rattling of the bolt or the like. Therefore, it is necessary to adjust the height using a level adjuster that supports the rising member from below. However, when a level adjuster is used, the height adjustment points are dispersed at multiple points on the rising piece and the level adjuster, so the reference becomes ambiguous and it may be difficult to ensure accuracy.

In contrast, in the height adjustment member 7 of this embodiment, the mounting surface 32 of the rising member 1 can be adjusted along the leg member 31. In this way, in the height adjustment member 7, the mounting surface 32 itself, which is the object of height adjustment, supports the rising member 1 from below, and can position the rising member in the vertical direction. Therefore, the height adjusting member 7 can accurately adjust the height of the rising member 1. Further, since the base member 30 and the foot members 31 are separate members from the rising member 1, the height can be adjusted independently from the rising member 1. Therefore, before installing the rising member 1, the height can be adjusted by simply arranging a plurality of height adjusting members 7 and adjusting the heights of each mounting surface 32 to the reference level. Adjustment is complete. As described above, the height of the rising member 1 can be easily and accurately adjusted.

In the height adjusting member 7, the leg member 31 is joined to the rising member 1. In this case, the leg member 31 used to adjust the height of the mounting surface 32 can be used as it is as a joint with the rising member 1. In addition, in the structure according to the above-mentioned comparative example, the end of the rising member is butted against the side surface of the rising piece and fixed with a bolt. In this case, if the rising member is inclined from a desired angle when viewed from above, it is necessary to adjust the attitude of the rising piece itself again. On the other hand, the height adjusting member 7 is joined to the rising member 1 by leg members 31 extending in the vertical direction. In this case, the stand-up member 1 can rotate about the foot member 31 with respect to the base member 30. Therefore, even if the stand-up member 1 is tilted from a desired angle when viewed from above, the position of the stand-up member 1 can be easily adjusted without changing the attitude of the height adjustment member 7. .

The foundation structure 100 includes the above-mentioned height adjustment member 7, a rising member 1, and a concrete portion 8 that is integrated with the rising member 1, and the rising member 1 is connected to the mounting surface 32. There is face-to-face contact. In this case, the rising member 1 is supported in a stable state on the mounting surface 32, so that the vertical positioning can be sufficiently performed.

In the foundation structure 100, the rising member 1 is configured to include a square steel pipe 20. The square steel pipe 20 has higher rigidity than a steel material with an open cross section. Therefore, when the square steel pipe 20 is used as the rising member 1 of the foundation structure 100, the number of reinforcement structures and level adjustment locations can be reduced. Therefore, the number of height adjustment members 7 can be reduced, and the effort required for height adjustment work can be reduced.

In the foundation structure 100, the height adjustment member 7 is integrated with the concrete portion 8. In this case, the height adjusting member 7 can support the rising member 1 with sufficient strength at the adjusted height position.

In the foundation structure 100, the base member 30 of the height adjustment member 7 is formed with a penetrating portion 34 in which the concrete portion 8 is disposed. In this case, the height adjustment member 7 is firmly fixed to the concrete part 8.

In the foundation structure 100, the foot members 31 of the height adjustment member 7 may be fixed to and integrated with the concrete portion 8. In this case, the height adjustment member 7 is firmly fixed to the concrete part 8.

The height adjustment method for the rising member 1 is a height adjusting method for adjusting the height of the rising member 1 that rises upward and extends in the horizontal direction in the basic structure 100, and includes the step of arranging the height adjusting member 7 described above. (height adjustment member arrangement step S20); and a step of adjusting the vertical position of the mounting surface 32 of the base member 30 along the leg member 31 (height adjustment step S30). By adjusting the height of the rising member 1, the same functions and effects as those of the height adjusting member 7 described above can be obtained.

The connecting structures 50A, 50B, and 50C include a pair of rising members 1 that rise upward in the basic structure 100 and extend in the horizontal direction, and connecting members 2, 3, and 4 that connect the pair of rising members 1 to each other. A space SP is provided between the ends 20c of the member 1 in the horizontal direction, and the connecting members 2, 3, and 4 are joined to the side surfaces 20b of the pair of rising members 1 so as to secure the space SP.

In the connection structures 50A, 50B, and 50C, the connection members 2, 3, and 4 are joined to the side surfaces 20b of the pair of rising members 1. In this case, the pair of rising members 1 has a configuration in which the side surfaces 20b of each other are continuous with each other by the connecting members 2, 3, and 4. Therefore, the pair of rising members 1 can be joined with high strength. Further, a space SP is provided between the ends 20c of the rising members 1 in the horizontal direction, and the connecting members 2, 3, and 4 are joined to the side surfaces 20b of the pair of rising members 1 so as to secure the space SP. be done. Therefore, a space SP is secured between the ends 20c of the rising members 1 even when the rising members 1 are connected by the connecting members 2, 3, and 4. Such a space SP can be effectively used depending on the purpose of the substructure 100. As described above, the space SP formed between the pair of rising members 1 can be effectively used while improving the strength of the connection between the pair of rising members 1.

In the connecting structures 50A, 50B, and 50C, the pair of rising members 1 extend in directions that intersect with each other in the horizontal direction, and the end portions 20c are close to each other with a space SP provided therebetween. It may be joined to the side surface 20b of the member 1 on the inner corner side. In this case, the strength of the connection between the pair of rising members 1 can be improved. Moreover, the space SP between the ends 20c of the rising member 1 can be used effectively.

In the connecting structure 50A, the pair of rising members 1 extend in directions that intersect with each other in the horizontal direction, and the end portions 20c are close to each other with a space SP provided therebetween. It may be joined to the side surface 20b. In this case, the strength of the connection between the pair of rising members 1 can be improved. Moreover, the space SP between the ends 20c of the rising member 1 can be used effectively.

In the connection structures 50A, 50B, and 50C, a nodal steel pipe 6 as a closing member may be arranged in the space SP. In this case, the space SP can be surrounded by the nodal steel pipe 6.

In the connection structures 50A, 50B, and 50C, the interior of the node steel pipe 6 may be filled with concrete. In this case, the space SP between the ends 20c of the rising member 1 can be used to improve the strength.

In the connection structures 50A, 50B, and 50C, the rising member 1 may be configured to include a square steel pipe 20. The square steel pipe 20 has higher rigidity than a steel material with an open cross section. Therefore, since the span of each rising member 1 can be increased, the number of locations to be connected by the connecting members 2, 3, and 4 can be reduced. Thereby, the workability of the foundation structure 100 can be improved.

The foundation structure 100 includes the above-described connection structures 50A, 50B, and 50C of the rising members 1, the rising members 1, and the concrete portion 8 that is integrated with the rising members 1. This basic structure 100 can provide the same functions and effects as the above-mentioned connecting structures 50A, 50B, and 50C.

The construction method of the foundation structure 100 includes a step of arranging a pair of rising members 1 that rise upward and extend in the horizontal direction in the foundation structure 100 (rising member arrangement step S40), and connecting the pair of rising members 1 with connecting members 2 and 3. , 4 (connection step S50), and in the step of arranging the pair of rising members 1, between the ends 20c of the rising members 1 in the horizontal direction. In the process of providing the space SP and connecting the connecting members 2, 3, and 4, the connecting members 2, 3, and 4 are joined to the side surfaces 20b of the pair of rising members 1 so as to secure the space SP. According to this method of constructing the foundation structure 100, the same actions and effects as those of the above-mentioned connecting structures 50A, 50B, and 50C can be obtained.

The invention is not limited to the embodiments described above.

For example, a basic structure 200 shown in FIG. 13 may be adopted. The foundation structure 200 is used as a foundation for a steel-framed building. The foundation structure 200 differs from the foundation structure 200 in that the top surface of the concrete part 202 reaches the top surface of the rising member 1, and in that a column 201 is provided in place of the node steel pipe 6 in the space SP of the node 15. It's different.

In the foundation structure 200, the rising member 1 is integrated with the concrete portion 8 not only on the bottom surface 20a but also on the side surface 20b of the square steel pipe 20. In this case, the square steel pipe 20 is buried in the concrete portion 8 and can be used as a slab-on-grade foundation structure.

In the connecting structures 50A, 50B, and 50C, a pillar 201 extending upward from the rising member 1 is used as a closing member. In this case, the space between the ends 20c of the rising members 1 can be used as the installation space for the pillars 201.

Further, a basic structure 300 as shown in FIG. 14 may be adopted. The foundation structure 300 differs from the foundation structure 200 in that braces 301 are provided between columns 201. In the basic structure 300, a connecting member 302 for a brace, which has a brace joint at the upper end of the aforementioned connecting members 2, 3, and 4, is employed as a connecting member. The brace 301 has a lower end supported by a connecting member 302 and an upper end supported by a column 201.

Furthermore, although the above-described foundation structure 100 had a total of four sections divided into two sections in the X-axis direction and two sections in the Y-axis direction, the mode of the sections is not particularly limited, and the shape of the building It can be set in any way depending on the

Moreover, the rising member 1 does not need to have the square steel pipe 20, and may be made of open cross-section steel such as channel steel, H-beam steel, or I-beam steel.

Furthermore, the connection structure between the rising members 1 does not necessarily need to be one using the connecting members 2, 3, and 4 as in the above-mentioned connection structures 50A, 50B, and 50C, and the rising members 1 may be welded together on site. , may be connected with high-strength bolts, or may be friction welded.
