Description

  The present invention relates to a vertical member joining method, a vertical member joining structure, and a receiving jig, which are suitable for use when, for example, disassembling a pillar member of an existing building and reusing it as a pillar member of a new building.

  Conventionally, it is important to recycle building components from the viewpoints of global environmental conservation and effective use of resources. For example, it has been proposed and implemented to effectively utilize components such as pillar members and beam members generated during building demolition work by recycling, reusing, and diverting them.

  On the other hand, for example, the concrete after dismantling the building's skeleton is used as land for concrete, road paving, etc., and compared to recycling such as melting steel pipes and steel frames and recycling them to new steel materials. However, at present, there is not enough support for re-membering that is used as a component of a building that newly constructs a component of an existing building.

  On the other hand, in Patent Document 1, when using a column member (vertical member) of an existing building as a column member of a newly constructed building, a pair of components that are carried into a construction site of a new building and disposed at a predetermined position. A method (so-called ring socket method) for joining the column members is disclosed. In this ring socket method, as shown in FIG. 9 and FIG. 10, so as to enclose (cover so as to cover) the joint portion 3 that abuts the lower end portion 1 a of the upper column member 1 and the upper end portion 2 a of the lower column member 2. ) Install the ring socket (tubular body) 4 and, for example, use a slant chute (introduction plate) 5 or a funnel, etc. to the clearance H between the ring socket 4 and the pair of pillar members 1 and 2 (no filling) Material) 6 is injected and filled, and the pair of upper and lower column members 1 and 2 are joined via the ring socket 4 and the non-shrink mortar 6.

  In this ring socket method, the inner peripheral edge (one end 7a) is fixed to the outer peripheral surface 2b of the lower column member 2 at a predetermined position on the upper end 2a side of the lower column member 2 by welding or the like. 2, a receiving jig (positioning temporary fitting) 7 provided with a ring-shaped receiving plate (receiving portion) 7b extending outward in the orthogonal direction (laterally outward) from the outer peripheral surface 2b. And this receiving jig 7 positions the ring socket 4 in a predetermined position by placing it on the ring-shaped receiving plate 7b, and supports the ring socket load. In the receiving jig 7, the ring-shaped receiving plate 7 b closes the lower opening H 1 of the gap H on the lower end 4 a side of the ring socket 4, so that there is no gap H between the ring socket 4 and the pair of column members 1 and 2. When the shrink mortar 6 is injected and filled, the non-shrink mortar 6 is prevented from leaking to the outside from the lower end 4 a side of the ring socket 4.

  Further, in the ring socket construction method, the lower end portion 4a of the ring socket 4 and the ring-shaped receiving plate 7b (receiving jig 7) are preliminarily supported so as to absorb the manufacturing and erection errors of the pair of pillar members 1, 2 and the ring socket 4. In some cases, a clearance (gap) of about 5 to 10 mm may be taken. In this case, as shown in FIG. 11, a packing material 8 such as a polyethylene resin foam is disposed on the ring-shaped receiving plate 7b, and the packing is interposed between the ring socket 4 and the ring-shaped receiving plate 7b. The material 8 prevents the non-shrink mortar 6 from leaking out from the lower end 4 a side of the ring socket 4.

JP-A-9-184201

  However, in the above conventional ring socket method, in order to reliably fill the gap H between the ring socket 4 and the pair of column members 1 and 2 without generating a gap, the viscosity before curing is almost very low as a filler. Liquid non-shrink mortar 6 is used. For this reason, it is difficult to prevent leakage of the non-shrink mortar 6 unless the lower end 4a of the ring socket 4 and the ring-shaped receiving plate 7b of the receiving jig 7 are completely sealed. And even if it is a case where the packing material 8 produced in advance is installed, as shown in FIG. 12, the production | generation of the ring socket 4 and a pair of pillar members 1 and 2, and the ring socket 4 produced with the construction method error In many cases, it is difficult to completely seal between the lower end 4a and the ring-shaped receiving plate 7b (gap P). Even if the gap P can be closed with the packing material 8, the non-shrinkable mortar 6 When filling (injecting), a new gap P is generated by the pressure and the non-shrinkable mortar 6 may leak, and a method for preventing leakage of the non-shrinkable mortar 6 easily and reliably has been strongly demanded.

  In view of the above circumstances, the present invention provides a vertical member joining method and a vertical member that can easily and surely prevent leakage of a filler such as non-shrink mortar and can suitably join vertical members such as column members. An object is to provide a joining structure of members and a receiving jig.

  Hereinafter, a vertical member joining method, a vertical member joining structure, and a receiving jig according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8. In this embodiment, for example, when a column member obtained by dismantling an existing building is reused as a column member of a new building, a column member joining method and a column member joining structure for joining a pair of upper and lower column members together And a receiving jig.

  As shown in FIG. 1, the column member joining structure 10 of the present embodiment includes a pair of upper and lower column members 1 and 2 (a pair of upper and lower vertical members that are constituent members of a building), a receiving jig 11, and a ring socket. (Tubular body) 4, a filler 6, and a closing material 12 are provided.

  The pair of pillar members 1 and 2 are made of, for example, steel and have a circular cross section. The pillar members 1 and 2 obtained by dismantling the existing building are transported to a factory or the like and subjected to processing such as cleaning. After that, it was brought into the construction site of a new building. And these pair of pillar members 1 and 2 are installed so that the lower end part 1a of the upper pillar member 1 and the upper end part 2a of the lower pillar member 2 may be faced | matched, and as the pillar members 1 and 2 of a new building Used.

  The receiving jig 11 is made of, for example, steel, and is formed in an annular shape with a receiving portion 13 and a rising portion 14 as shown in FIGS. 1 and 2A. The receiving portion 13 is formed in a disk shape having an inner hole 13 a having the same size as the cross-sectional area of the column member 2 in the center, and the rising portion 14 extends upward from the outer peripheral edge (other end) 13 b of the receiving portion 13. It is formed in an annular shape that extends along the outer peripheral edge 13 b of the receiving portion 13. And this receiving jig 11 fixes the inner periphery (one end) 13c of the receiving part 13 which forms the inner hole 13a to the outer peripheral surface 2b of the lower column member 2 by welding etc., for example, It is integrally attached at a predetermined position on the upper end 2a side. By attaching to the lower column member 2 in this way, the receiving jig 13 extends from the outer peripheral surface 2 b of the lower column member 2 to the outer side in the orthogonal direction (laterally outer side), and rises with the receiving unit 13. An annular space 15 that opens upward is formed by the portion 14 and the outer peripheral surface 2 b of the column member 2 below.

  The receiving jig 11 according to the present invention is formed so as to be separable in the circumferential direction, for example, as shown in FIG. 2 (b), and the divided receiving jig pieces 11a and 11b are respectively provided to predetermined pillar members 2 below. At the same position, the receiving jig pieces 11a and 11b adjacent to each other in the circumferential direction of the lower column member 2 are fixed together with bolts 16 and nuts 17 to be attached to the lower column member 2. You may be comprised so that a cyclic | annular form may be exhibited in a state.

  The ring socket 4 is a steel tubular body, and is the same as the ring socket used in the conventional ring socket method. As shown in FIG. 1, the ring socket 4 is formed in a cylindrical shape having an inner diameter larger than the outer diameter of the column members 1 and 2 and an outer diameter smaller than the outer diameter of the receiving jig 11. Yes. The ring socket 4 is installed so as to cover the pair of column members 1 and 2 so as to include the joint 3 in which the upper end 2a and the lower end 1a of the pair of upper and lower column members 1 and 2 are abutted with each other. At this time, the ring socket 4 is installed in a state in which a predetermined gap H is ensured between the outer peripheral surfaces 1b and 2b of the pair of column members 1 and 2, and the lower end portion 4a thereof is a receiving jig 11. It is installed so that it may be arranged in the space 15 formed by the above.

  In addition, the cylindrical body 4 which concerns on this invention is formed so that it can divide | segment, for example in the circumferential direction similarly to the receiving jig 11, and the divided | segmented cylindrical body piece of the junction part 3 of a pair of pillar members 1 and 2 is each respectively By arranging in parallel in the circumferential direction and adjacent cylindrical body pieces together with bolts and nuts or the like, the cylindrical body pieces may be formed to have a cylindrical shape.

  Like the filler used in the conventional ring socket method, the filler 6 is a substantially liquid non-shrink mortar having a very low viscosity before curing (during filling), and the ring socket 4 and the pair of column members 1. 2 is filled in the gap H between the two. Thus, by filling the gap H with the filler 6, the pair of pillar members 1 and 2 are integrally joined via the cured filler 6 and the ring socket 4.

  The plugging material 12 is a mortar that exhibits the same strength as the filler 6 or higher strength than the filler 6, and cures in a short time of about 30 minutes, for example. The closing material 12 is injected into the space 15 formed by the receiving jig 11. At this time, the closing member 12 is provided so that the upper surface (liquid surface at the time of injection) 12a is positioned above the lower end portion 4a of the ring socket 4 disposed in the space 15.

  Next, a method of joining the pair of upper and lower column members 1 and 2 by the column member joining structure 10 having the above configuration will be described, and the vertical member joining method, the vertical member joining structure 10 and the receiving jig of the present embodiment will be described. 11 will be described.

  First, the column members 1 and 2 obtained by dismantling the building are brought into a factory, etc., and cleaning, length adjustment, etc. are performed so that the column members 1 and 2 can be used as the building column members 1 and 2 Apply processing. Make adjustments. In the present embodiment, at the stage where the processing is performed in this manner, one end 13c of the inner peripheral edge of the receiving portion 13 is previously placed at a predetermined position on the upper end portion 2a side of the lower column member 2 by, for example, welding. The receiving jig 11 is fixedly attached to the outer peripheral surface of the column member 2 (receiving jig attaching step).

  Next, the pillar members 1 and 2 processed as described above are carried into a site where a building is newly constructed, and a pair of upper and lower pillar members 1 and 2 are disposed at predetermined positions by appropriate means. At this time, as shown in FIGS. 3 and 4, the axes O1 and O2 are coaxially arranged so that the lower end 1a of the upper column member 1 and the upper end 2a of the lower column member 2 are abutted. A pair of pillar members 1 and 2 are disposed in the vertical member installation process.

  Moreover, in this embodiment, when arrange | positioning a pair of pillar members 1 and 2 in this way, the ring socket 4 is installed in the step before installing the upper pillar member 1 (cylindrical body installation process). ). The ring socket 4 has a lower end portion in a space 15 surrounded by the receiving portion 13 and the rising portion 14 of the receiving jig 11 which is attached to the lower column member 2 in advance and the outer peripheral surface 2b of the lower column member 2. 4a is arranged, and the lower column member 2 and the mutual axes O2 and O3 are arranged coaxially. In this embodiment, as shown in FIG. 4, a spacer 20 is installed on the receiving portion 13 of the receiving jig 11, and the ring socket 4 is installed so as to be placed on the spacer 20. Thus, the ring socket 4 is supported by the receiving jig 11 via the spacer 20, and is installed at a predetermined position with a gap between the lower end portion 4 a and the receiving portion 13. In installing the ring socket 4, it is not always necessary to provide the spacer 20. For example, the ring socket may be installed in a state where the ring socket is lifted to a predetermined position using a chain block or the like.

  And in the state which installed the ring socket 4 in this way, as shown in FIG.3 and FIG.4, the upper pillar member 1 is inserted in the inside from the upper end part 4b side of the ring socket 4, and this upper pillar member 1 is inserted. The upper column member 1 is arranged so that the lower end portion 1a of the lower column member 1 is abutted with the upper end portion 2a of the lower column member 2 and the lower column member 2 and the axes O1 and O2 are arranged coaxially. Install. Thereby, the ring socket 4 is installed in a state in which a predetermined gap H is secured between the pair of column members 1 and 2 and so as to enclose the joint portion 3 of the pair of column members 1 and 2. It will be.

  Here, in this embodiment, the receiving jig 11 is attached to the lower column member 2 in advance, and the ring socket 4 is installed at a stage before the upper column member 1 is installed. On the other hand, when the receiving jig 11 and the ring socket 4 are formed so as to be split as described above, the lower pillar member 2 is installed at a predetermined position at the construction site of the new building. When the receiving jig 11 is attached to a predetermined position on the upper end 2a side of the column member 2 or when the pair of column members 1 and 2 are respectively installed at predetermined positions, the receiving jig 11 and the ring socket 4 are installed. You may make it do.

  Next, at the stage where the pair of column members 1 and 2 and the ring socket 4 are installed, as shown in FIG. 5, the receiving portion 13 and the rising portion 14 of the receiving jig 11 and the outer peripheral surface 2 b of the lower column member 2. The closing material 12 is injected into the enclosed space 15 using, for example, an oblique chute (introduction plate) 5 or a funnel (blocking step). At this time, as shown in FIG. 6, the liquid level (upper surface 12 a) of the plugging material 12 such as liquid non-shrink mortar is arranged above the lower end portion 4 a of the ring socket 4 by, for example, about several centimeters. Inject. That is, the blocking material 12 is injected to a position higher than the lower end 4 a of the ring socket 4. The plugging material 12 injected in this way is inserted into the gap H from the lower opening H1 of the gap H between the ring socket 4 and the pair of pillar members 1 and 2 so as to bury the lower end 4a side of the ring socket 4 together with the injection. It penetrates into the ring socket 4 and hardens in a short time of about 30 minutes. As a result, the lower opening H <b> 1 of the gap H is closed by the closing material 12.

  At this time, for example, as shown in FIG. 7, even when manufacturing and construction errors of the ring socket 4 and the pair of pillar members 1 and 2 occur, the position is higher than the lower end portion 4 a of the ring socket 4. By injecting the closing material 12 to the end, the closing material 12 is surely filled into the gap P between the lower end portion 4a of the ring socket 4 and the receiving portion 13 of the receiving jig 11, and this closing material 12 is further connected to the ring socket. 4 and the pair of pillar members 1 and 2 enter the gap H from the lower opening H1 of the gap H, so that the lower opening H1 of the gap H is surely blocked by the hardened blocking material 12. In addition, by injecting the closing material 12 to a position higher than the lower end 4a of the ring socket 4 in this way, regardless of the size of the error, the lower opening of the gap H can be easily and reliably cured with the hardening of the closing material 12. H1 is closed (sealed). Further, when the closing material 12 is cured, the ring socket load is reliably supported by the receiving jig 11 through the closing material 12.

  Next, after the closing member 12 is cured and the lower opening H1 of the gap H is closed as described above, the upper opening of the gap H on the upper end 4b side of the ring socket 4 as shown in FIG. From H2, the filler 6 is injected and filled into the gap H (filling step). Even when a substantially liquid non-shrink mortar is used as the filler 6 before curing (at the time of filling), the lower opening H1 of the gap H is formed by the cured plug 12. Since it is blocked, the filler 6 is reliably prevented from leaking out from the lower end 4a side of the ring socket 4. Further, unlike the case where the conventional packing material 8 is used, when the filler 6 is filled (injection), a new gap P is not generated by the pressure, and the filler 6 does not leak.

  Thereby, even if the ring socket 4 and the pair of pillar members 1 and 2 are produced and built, an error occurs between the ring socket 4 and the pair of pillar members 1 and 2, as shown in FIG. The gap 6 is preferably filled with the filler 6, the filler 6 is cured, and the pair of column members 1 are reliably secured in a suitable state in which the joint strength is not reduced via the ring socket 4 and the filler 6. 2 are joined.

  Therefore, in the column member joining method, the column member joining structure 10, and the receiving jig 11 according to the present embodiment, the receiving jig 11 includes the receiving portion 13 and the rising portion 14. 4 and the pair of pillar members 1 and 2, the space is such that the liquid surface 12 a of the blocking material 12 is disposed above the lower end portion 4 a of the ring socket 4, even when manufacturing and construction errors occur. By injecting the closing material 12 into the opening 15, the lower opening H <b> 1 of the gap H can be easily and surely closed with the closing material 12 as the closing material 12 is cured regardless of the size of the error. And since the lower opening part H1 of the said clearance gap H is obstruct | occluded with the obstruction | occlusion material 12 in this way, the fillers 6, such as a non-shrink mortar, are made into the clearance gap H between the ring socket 4 and a pair of pillar members 1,2. Even if it is filled, it becomes possible to reliably prevent the filler 6 from leaking out from the lower end 4a side of the ring socket 4.

  Therefore, compared with the conventional ring socket construction method, even when the ring socket 4 and the pair of pillar members 1 and 2 are manufactured and erected, there is an error between the ring socket 4 and the pair of pillar members 1 and 2. The gap 6 is preferably filled with the filler 6, and the pair of column members 1 and 2 can be reliably joined through the ring socket 4 and the filler 6 in a suitable state in which the joint strength is not reduced. It becomes possible.

  As mentioned above, although one embodiment of the joining method of the vertical member, the joining structure of the vertical member, and the receiving jig according to the present invention has been described, the present invention is not limited to the above-described one embodiment, and departs from the gist thereof. It is possible to change appropriately within the range not to be. For example, in the present embodiment, the description has been made on the assumption that the pair of column members 1 and 2 having a circular cross section are joined, and accordingly, the receiving jig 11 is formed in an annular shape. The receiving jig 11 only needs to be formed to include a receiving portion 13 and a rising portion 14. For example, in the case where a pair of vertical members 1 and 2 are formed in a square cross section, the vertical member 1, What is necessary is just to change the shape of the receiving jig 11 suitably according to 2 cross-sectional shape.

  Moreover, although this embodiment demonstrated as what joins a pair of pillar members 1 and 2, this invention is a case where a pillar member (upper vertical member) and a pile (lower vertical member) are joined, for example. It is also possible to apply to. That is, the present invention can be applied to any case where a pair of upper and lower vertical members are joined, and the vertical members are not necessarily limited to column members.

  In the present embodiment, the filler 6 has been described as being non-shrink mortar, but the filler according to the present invention is filled in the gap between the cylindrical body and the pair of upper and lower vertical members, As long as the cylindrical body and the pair of vertical members can be integrated and the pair of upper and lower vertical members can be joined together, for example, a resin or the like may be used.

  Further, in the present embodiment, the description has been made on the assumption that the closing material 12 is a mortar that is the same as or higher in strength than the filling material 6, but the closing material according to the present invention is a receiving jig. It is possible to close the lower opening portion of the gap between the cylindrical body and the pair of upper and lower vertical members by injecting into a space surrounded by the receiving portion and the rising portion of the lower portion and the outer peripheral surface of the lower vertical member. If it exists, for example, it may be a resin or the like, and the strength is not particularly limited, and is not necessarily mortar.
