Description

  The present invention relates to a structure connecting structure and a building.

  In a building such as a house, it is known that an intermediate floor lower than the upper and lower floors is formed between the upper floor and the lower floor, and the intermediate floor can be used as a storage space. Yes. In some of such buildings, the frame structure includes a main frame that forms the entire structure of the building and a sub frame that forms a storage space. For example, in Patent Document 1, the pillars constituting the main frame are supported on the rising part of the foundation, while the pillars constituting the sub-frame are connected to the support fittings provided on the side surfaces of the rising part and the side of the foundation. A supporting framework structure is disclosed. In this case, since the secondary frame is set independently from the main frame, the structure of the main frame can be calculated without taking the secondary frame into account. As a result, the conventional building and the main frame are designed to be the same. can do.

JP 2007-315166 A

  However, since the frame structure of Patent Document 1 is a structure that supports a column on the side of the rising portion of the foundation, it is more stable than a general building structure that supports the column from below on the rising portion of the foundation. There is concern in terms. Moreover, since the structure of the said patent document 1 is a structure which supports a pillar with a supporting member, the load of the pillar (as a result, a sub frame) which is a heavy article acts on a supporting member, and the load acts on a foundation as a result. For this reason, the connection structure between the support member and the foundation is required to have a structure that stably supports the load, but the document 1 does not disclose the details of the connection structure.

  Such a problem is not only a problem that occurs when the pillar is supported on the side of the rising part of the foundation, but also a problem that occurs similarly when a beam or other structure is supported on the side of the rising part of the foundation. It is.

  The present invention has been made in view of the above circumstances, and provides a structure connection structure and a building that can stably support the structure when the structure of the building is supported on the side of the foundation. The main purpose is to do.

  In order to solve the above-described problem, the structure connection structure according to the first aspect of the present invention is a structure connection structure in which a building structure is connected to the foundation via an anchor fitting partially embedded in a rising portion of the foundation of the building. The anchor bracket includes a connecting portion that is exposed on a side surface of the rising portion of the foundation and connects the structure, and an anchor portion that extends inward from the connecting portion to the foundation, and the anchor portion includes: Of the plurality of foundation reinforcing bars disposed in the foundation, the transverse reinforcing bars intersect with the transverse reinforcing bars extending in the longitudinal direction of the foundation.

  According to the present invention, a building structure (for example, a column or a beam) is connected to the connecting portion of the anchor bracket exposed on the side surface of the rising portion of the foundation, thereby supporting the building structure on the side of the rising portion. can do. In this case, the load of the structure of the building acts on the anchor fitting, but the anchor portion extending inward of the foundation from the connecting portion in the anchor fitting is located above the transverse reinforcement extending in the longitudinal direction of the foundation. Since they intersect, the load acting on the anchor fitting can be supported not only by the foundation concrete but also by the horizontal reinforcing bars. Thereby, when supporting the structure of a building by the side of a foundation, the structure can be supported stably.

  Moreover, the anchor part is good to be formed by the deformed reinforcing bar. Thereby, since the adhesiveness of the anchor part with respect to the concrete in a foundation can be improved by the unevenness | corrugation (node) of a deformed reinforcing bar, the effect which raises prevention of the anchor part from detaching from the foundation can be expected.

  In the structure connecting structure according to a second aspect of the present invention, in the first aspect, the anchor portion extends in the thickness direction of the rising portion of the foundation and intersects the horizontal reinforcing bar above the horizontal reinforcing bar. And a second anchor portion bent with respect to the first anchor portion.

  According to the present invention, in the anchor portion, the first anchor portion intersects the horizontal reinforcing bar above the horizontal reinforcing bar, so that the load of the structure acting on the anchor metal fitting is supported not only by the basic concrete but also by the horizontal reinforcing bar. be able to. Therefore, the effect of the first invention can be obtained. Moreover, in the anchor part, since the 2nd anchor part is bent and provided with respect to the 1st anchor part extended in the thickness direction of the rising part of a foundation, the full length of an anchor part is longer than the thickness dimension of the rising part. can do. Thereby, compared with the case where the 2nd anchor part is not provided in an anchor part, the fixability of the anchor part with respect to the concrete in a foundation can be improved, As a result, the fall prevention effect from the foundation of an anchor part can be improved. it can.

  The structure connection structure of a third invention is characterized in that, in the second invention, the second anchor portion intersects the basic reinforcing bar on the side opposite to the connecting portion with the basic reinforcing bar interposed therebetween. To do.

  According to the present invention, since the second anchor portion of the anchor portion intersects with the foundation rebar on the side opposite to the connecting portion with the foundation rebar interposed therebetween, an external force is applied to the structure and the foundation is attached to the anchor fitting. When a pulling force is applied, the pulling force can be received not only by the foundation concrete but also by the foundation rebar. Thereby, the structure can be connected to the side surface of the foundation in a more stable state.

According to a fourth aspect of the present invention, there is provided the structure connecting structure according to any one of the first to third aspects, wherein the anchor fitting includes two connecting portions, and each connecting portion is provided at a rising portion of the foundation. According to the present invention, the connecting portions are exposed on both side surfaces of the rising portion of the foundation. The anchor portions are provided so as to be exposed on both side surfaces, and the anchor portions are provided so as to connect the connecting portions. The structure of the building can be connected to each of the two connecting portions. That is, it is possible to support two structures on one side of the foundation. Further, since the anchor portion intersects the horizontal reinforcing bar above the horizontal reinforcing bar, the load of the two structures acting on the anchor fitting can be supported not only by the basic concrete but also by the horizontal reinforcing bar.

  Here, the same effect can be obtained even if two anchor fittings having only one connecting portion are used. In this case, however, the anchor portions interfere with each other within the foundation when the anchor fitting is arranged on the foundation. It is necessary to consider not to. In that respect, according to the present invention, there is an advantage that the above-described effect can be obtained without such consideration.

  According to a fifth aspect of the present invention, there is provided the structure connecting structure according to any one of the first to third aspects, wherein the connecting portion is provided with the anchor portions on the left and right with respect to a connection reference position of the structure, Each anchor part is arranged asymmetrically with respect to the connection reference position.

  According to the present invention, in the anchor metal fitting, the anchor portion is disposed asymmetrically with respect to the coupling reference position of the structure in the coupling portion. Thereby, when providing the same two anchor metal fittings in the same position in the longitudinal direction of the foundation on both sides of the rising part of the foundation, the anchor parts can be provided without interfering with each other.

  In the structure connecting structure according to a sixth aspect of the present invention, in any one of the first to fifth aspects of the invention, a plurality of the horizontal reinforcing bars are arranged in the vertical direction at predetermined intervals in the foundation. The anchor metal fitting includes a plurality of the anchor portions at predetermined intervals in the vertical direction, and each of the plurality of anchor portions intersects with the respective horizontal reinforcing bars above the separate horizontal reinforcing bars. To do.

  According to the present invention, since the plurality of anchor portions intersect with the respective horizontal reinforcing bars above the respective horizontal reinforcing bars, the load of the structure acting on the anchor metal fitting is applied to the plurality of horizontal reinforcing bars in addition to the basic concrete. Can be supported by. In this case, since the load of the structure can be distributed to a plurality of horizontal reinforcing bars, the load acting on the horizontal reinforcing bars (per one piece) should be reduced compared to the case where the load is supported by one horizontal reinforcing bar. Can do. Thereby, when supporting the structure of a building by the side of a foundation, it can support in the state stabilized further.

  The building of the seventh invention has, as a framework structure of the building, a main frame that constitutes the entire structure of the building, and a sub frame that forms a predetermined space in the building and is set independently of the main frame In the building, a pillar constituting the main frame is installed on the upper surface of the rising part of the foundation, and a pillar constituting the sub-frame is provided on a side surface of the rising part. It is connected by the structure connection structure as described in any one of the above.

The contact plate portion 46 a of the bracket 46 is fixed to the anchor metal fitting 41 by fastening a bolt (not shown) to the embedded nut 44 of the connection plate 42.

  A lower portion of the skip pillar 47 is disposed inside the bracket 46. The skip column 47 includes a column main body 48 made of H-shaped steel and a beam receiving plate 49 fixed to the upper end portion of the column main body 48. The column main body 48 is disposed inside the bracket 46 with the outer surface of the flange portion 48a opposed to the inner surface of the side plate portion 46b of the bracket 46, and the flange portion 48a is disposed in the bracket 46 in the disposed state. The side plate portion 46b is fixed with bolts or the like. On the other hand, the beam receiving plate 49 is a flat sheet metal member, and is fixed to the upper end portion of the column main body 48 by welding or the like with the plate surface facing upward.

A skip floor material (not shown) is installed at the upper part of the skip floor beam 51 and a skip ceiling material is installed at the lower part of the skip floor beam 51, so that the boundary between the lower storage (A part) and its upper space is formed on the first floor portion 12. Is built.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  A skip column 47 was connected via a bracket 46 to a connection plate 42 of an anchor fitting 41 exposed on the side surface of the rising portion of the foundation 11. Thereby, the skip pillar 47 can be supported by the side of the foundation 11. Further, the anchor portion 43 of the anchor fitting 41 is made to intersect with the horizontal reinforcing bar above the upper main reinforcing bar 55 or the abdominal muscle 56 (hereinafter referred to as horizontal reinforcing bar) as the horizontal reinforcing bar in the foundation 11. Therefore, the load of the skip column 47 acting on the anchor fitting 41 can be supported not only by the concrete of the foundation 11 but also by the horizontal reinforcing bars. Therefore, when the skip column 47 is supported on the side of the foundation 11, the skip column 47 can be stably supported.

  The anchor portion 43 is configured by including a horizontal portion 43b extending in the thickness direction of the rising portion of the foundation 11 and a hanging portion 43c extending downward from the separated end portion of the horizontal portion 43b. Here, since the drooping portion 43c extends in a direction orthogonal to the thickness direction of the rising portion of the foundation 11, the total length of the anchor portion 43 can be made longer than the thickness dimension of the rising portion. Thereby, compared with the structure in which the hanging part 43c is not provided in the anchor part 43, the fixing property of the anchor part 43 with respect to the concrete in the foundation 11 can be enhanced, and as a result, the anchor part 43 can be prevented from coming off from the foundation 11. Can enhance the effect.

  Further, the hanging portion 43c of the anchor portion 43 is made to intersect the horizontal reinforcing bar on the side opposite to the connecting plate 42 with the horizontal reinforcing bar interposed therebetween. Thereby, when an external force is applied to the building 10 and a pulling force from the foundation 11 acts on the anchor fitting 41, the pulling force can be received not only by the concrete of the foundation 11 but also by the horizontal reinforcing bars. Thereby, the skip pillar 47 can be connected to the side surface of the foundation 11 in a more stable state.

  The anchor metal fitting 41 includes a plurality of anchor portions 43A and 43B at predetermined intervals in the vertical direction, and the upper anchor portion 43A of the plurality of anchor portions 43A and 43B intersects with the upper end main reinforcement 55 above the upper end main reinforcement 55. The lower anchor portion 43B intersects the abdominal muscle 56 above the abdominal muscle 56. As a result, the load of the skip column 47 can be distributed to the upper main muscle 55 and the abdominal muscle 56, and therefore compared to a case where the load is supported by one horizontal reinforcing bar (for example, the upper main muscle 55) (per one). The load acting on the horizontal rebar can be reduced. Thereby, in the case where the skip column 47 is supported on the side of the foundation 11, it can be supported in a more stable state.

  The upper anchor portion 43A and the lower anchor portion 43B are provided in pairs in the horizontal direction at predetermined intervals, and the pair of anchor portions 43A (43B) are provided on the basis of the arrangement position of the embedded nut 44, that is, the connecting plate. 42 is arranged asymmetrically with reference to the center position in the width direction. Thereby, when providing the same two anchor metal fittings 41 so that each connection plate 42 may oppose on both sides of the standup | rising part 11b of the foundation 11, it prevents that the mutual anchor parts 43 interfere in the foundation 11. FIG. be able to.

  Since the anchor portion 43 is formed of the deformed reinforcing bar, the adhesion of the anchor portion 43 to the concrete in the foundation 11 can be enhanced by the irregularities (nodes) of the deformed reinforcing bar. Thereby, the effect which raises the prevention of detachment from the foundation 11 of the anchor part 43 can be expected.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) Instead of the anchor fitting 41 in the above embodiment, an anchor fitting including two connecting plates 42 may be used. A specific example thereof will be described below with reference to FIG. As shown in FIG. 5, the anchor fitting 65 includes two opposing connection plates 42 and an anchor portion 66 that connects the connection plates 42. The anchor portion 66 includes a horizontal portion 66a extending between the connecting plates 42 in a direction perpendicular to the plate 42, and a pair of connecting portions 66b extending downward from both longitudinal ends of the horizontal portion 66a. The connecting portions 66b are fixed to the opposing surfaces of the connecting plates 42 by welding or the like, so that the connecting plates 42 and the anchor portion 66 are integrated. A plurality of anchor portions 66 are provided at predetermined intervals in the vertical direction. In the present embodiment, as shown in FIG. 5, an upper anchor portion 66 </ b> A and a lower anchor portion 66 </ b> B are provided as the anchor portion 66.

  The anchor metal fitting 65 is provided in a state where the two connecting plates 42 are exposed on both side surfaces of the rising portion of the foundation 11. Specifically, each connecting plate 42 is provided such that its plate surface is substantially flush with the side surface of the rising portion of the foundation 11. A skip column 47 is connected to each connection plate 42 via a bracket 46. That is, if this anchor metal fitting 65 is used, the two skip pillars 47 can be supported on the side of the foundation 11 with respect to the one foundation 11.

  The upper anchor portion 66 </ b> A has a horizontal portion 66 a that intersects the upper end main muscle 55 above the upper main muscle 55, and the lower anchor portion 66 </ b> B has a horizontal portion 66 a that intersects the abdominal muscle 56 above the abdominal muscle 56. ing. Therefore, the load of the skip column 47 acting on the anchor fitting 65 can be supported not only by the concrete of the foundation 11 but also by the upper end main reinforcement 55 and the abdominal muscle 56. Thereby, in the case where the two skip columns 47 are supported on both sides of the foundation 11, both the skip columns 47 can be stably supported.

  Here, the same effect can be obtained even if two anchor fittings 41 in the above embodiment are used. In this case, when the anchor fitting 41 is arranged on the foundation 11, the anchor portions 43 are arranged in the foundation 11. Care must be taken not to interfere. In that respect, if the anchor metal fitting 65 is used, the above-described effect can be obtained without taking such consideration into consideration.

  (2) In the above embodiment, the structure in which the skip pillar 47 is connected to the side surface of the foundation 11 via the anchor fitting 41 has been described, but this is changed to the floor beam via the anchor fitting 41 on the side surface of the foundation 11. Such other structures may be connected. For example, if a floor beam is connected to the side surface of the foundation 11, the foundation 11 can be reduced correspondingly, so that the number of construction steps can be reduced.

  (3) The shape of the anchor portion 43 is not necessarily limited to the shape in the above embodiment, and may be other shapes. For example, in the above-described embodiment, the anchor portion 43 is provided with the hanging portion 43c extending downward from the separated side end portion of the horizontal portion 43b. You may provide the site | part extended in a direction. For example, if the anchor part 43 is provided with a part extending along the longitudinal direction of the foundation 11 from the separated end of the horizontal part 43b, the part can be extended longer than the hanging part 43c in the above embodiment. The total length of the anchor portion can be increased accordingly. Therefore, the anchoring property of the anchor part to the concrete in the foundation 11 can be further enhanced. In this case, the part may be disposed along the horizontal reinforcing bar such as the upper end main reinforcing bar 55 and may be bound to the horizontal reinforcing bar using a binding wire or the like. Thereby, since the anchor part 43 can be integrated with respect to a horizontal reinforcing bar, the effect which improves the connection intensity | strength with the anchor metal fitting 41 and the foundation 11 can be anticipated. Furthermore, if the part is made to intersect the ribs 58 on the opposite side of the connecting plate 42 with the ribs 58 interposed therebetween, an external force is applied to the building 10, and the pulling force from the foundation 11 to the anchor bracket 41 is increased. The pulling force can be received not only by the concrete of the foundation 11 but also by the stirrup 58.

  Further, instead of the hanging portion 43c in the above-described embodiment, the anchor portion has a hook portion bent in a semicircular shape from the separated end portion of the horizontal portion 43b, and extends from the hook portion to the connecting plate 42 side and the horizontal portion. You may provide the return part arrange | positioned above 43b. In this case, if the anchor part 43 is arranged so that the horizontal reinforcing bar passes between the return part and the horizontal part 43b, the returning part can intersect the horizontal reinforcing bar above the horizontal reinforcing bar. Similar effects can be obtained. In this case, since the hook portion intersects the horizontal reinforcing bar on the side opposite to the connecting plate 42 with the horizontal reinforcing bar interposed therebetween, the force acting on the anchor fitting 41 is received not only by the concrete of the foundation 11 but also by the horizontal reinforcing bar. Can do. Thereby, the skip pillar 47 can be connected to the side surface of the foundation 11 in a more stable state.

  The anchor portion 43 is not necessarily provided with the hanging portion 43c, and the hanging portion 43c may not be provided.

  (4) In the above embodiment, the plurality of anchor portions 43 are arranged at predetermined intervals in the vertical direction and the horizontal direction, respectively, but the manner of arrangement of these anchor portions 43 is not necessarily limited thereto. Is optional. For example, the plurality of anchor portions 43 may be arranged at predetermined intervals only in the vertical direction or only in the horizontal direction. Further, it is not always necessary to provide a plurality of anchor portions 43, and only one anchor portion 43 may be provided.

  (5) Although the skip column 47 is connected to the anchor fitting 41 via the bracket 46 in the above embodiment, it may be connected without using the bracket 46. For example, when the skip column is made of C-shaped steel, it is considered that the outer surface of the skip column web is brought into contact with the exposed surface of the connection plate 42 and the skip column is directly connected to the connection plate 42 with a bolt or the like. It is done.
