Description

  The present invention can be provided in an opening defined by the seismic panel independently of the installation of the seismic panel provided in the frame, and is a structure necessary as a seismic structure built in the frame. The present invention relates to a seismic frame structure that can ensure strength and is easy to construct and a construction method thereof.

  For example, Patent Literature 1 is known as a frame that is provided with an earthquake-proof reinforcement and an opening. The “seismic reinforcement structure” of Patent Document 1 is a seismic reinforcement structure in which a seismic wall is provided in a frame surrounded by columns and beams to improve the seismic performance of an existing structure. And a joining member that is disposed along the lower side of the passage opening and that has at least one end projecting laterally of the passage opening and embedded in the wall body.

Just above the passage opening, the concrete wall portion between the upper beam and the upper beam is a hanging wall from the upper beam.

On the other hand, Patent Document 2 is known as a seismic wall having a configuration different from that of Patent Document 1. The “wall unit, earthquake-resistant wall and construction method thereof” of Patent Document 2 are a precast concrete panel, a steel plate brace element formed in an X shape and provided inside the panel, and other panels adjacent to the brace element.

  In Patent Document 1, a joining member is provided on the lower side of the passage opening. This joining member is one in which at least one end is embedded in the wall body and fixed to the wall body with a shear key, and is integrated with the wall body. For this reason, in the construction of Patent Document 1, the wall body is constructed on site or the wall body in which the joining members are integrated is incorporated. The on-site construction of the wall body with the concrete placement is complicated, and particularly in the case of an existing structure, it is unsuitable for construction while the structure remains in use. In addition, when a wall body in which the joining members are integrated is incorporated, there is a problem in that high dimensional accuracy is required for the wall body itself and a frame in which the wall body is incorporated.

  Further, in Patent Document 1, the strength of the hanging wall immediately above the passage opening is ensured by the wall portion of the passage opening and the lower wall below the upper beam, which is different from the lower side of the passage opening provided with the joining member. There was a risk that the required strength could not be ensured. That is, the concrete wall portion directly above the passage opening has a lower strength than other wall portions extending from the upper beam to the lower beam, and therefore, the opening height of the passage opening is lowered to ensure the required strength. In order to secure a high opening height, there is a problem that some reinforcement must be applied to the wall body portion immediately above the passage opening separately from the other wall body portions.

  And for earthquake-resistant walls constructed by a combination of wall units as in Patent Document 2, an earthquake-resistant frame structure that enables formation of a reasonable opening in terms of structural strength, which is different from Patent Document 1, and its construction method. Was devised.

A connection plate for transmitting a horizontal force between the left and right edges of the opening is provided.

  The earthquake-resistant panel includes a brace element.

  The connection plate is joined to the lower beam and the upper beam by a buckling prevention anchor.

  The connecting plate is joined to the left and right end edges of the opening so as to be slidable in the vertical direction.

  The connection plate is in contact with the left and right edges of the opening, and is provided between a pair of support plate members that receive the horizontal force in the frame, and a horizontal plate that transmits the horizontal force. It is composed of a plate material, and a rib material that is interposed between the plate surface of the horizontal plate material and the plate surface of the pressure bearing plate material, and transmits a horizontal force from the pressure bearing plate material to the horizontal plate material. To do.

  The construction method of the seismic frame structure according to the present invention is a construction method for constructing the above-mentioned seismic frame structure, which is disposed at a position where the opening of the frame is formed, and is arranged on the lower beam and the upper beam. Suspending the connection plate from the inner surface of the frame and building the earthquake-resistant panel between the connection plate and the column, and the connection plate, the lower beam, and the upper A step of filling an adhesive between the beam and between the earthquake-resistant panel and the inner surface of the frame.

  In the seismic frame structure and its construction method according to the present invention, the seismic panel can be provided in an opening defined by the seismic panel independently of the installation of the seismic panel provided in the frame. The structural strength required for the seismic structure to be constructed can be secured, and construction can be performed easily and smoothly.

  Hereinafter, a preferred embodiment of an earthquake-resistant frame structure and its construction method according to the present invention will be described in detail with reference to the accompanying drawings. First, the earthquake-resistant frame structure according to the present embodiment will be described with reference to FIG. In various existing structures, a frame is surrounded by a pair of left and right columns 1 and a pair of upper and lower upper and lower beams 2 and 3 provided between the upper and lower ends of the columns 1 in a horizontal direction. A frame 4 such as a frame is formed.

  A seismic wall 5 is constructed in the frame 4. In the present embodiment, the earthquake resistant wall 5 is constructed by disposing a plurality of earthquake resistant panels 6, thereby constituting an earthquake resistant frame structure. In the illustrated example, four seismic panels 6 arranged vertically and horizontally are arranged close to the left and right pillars 1, respectively. An opening 7 is formed between the earthquake resistant walls 5 constituted by these earthquake resistant panels 6.

  Each seismic panel 6 is mainly composed of a rectangular flat PCa panel material 8, a steel plate brace element 9 provided inside the panel material 8, and the brace element 9 joined to the brace element 9 of another seismic panel 6. And a joining end for the purpose. The panel material 8 is formed with a joint portion 10 having its four corners recessed. The brace element 9 is formed in an X shape having a dimension that reaches the joint portion 10 along the diagonal direction of the panel material 8.

  The joining end is formed at the end of the brace element 9 exposed at each joining part 10. Joining of the adjacent earthquake-resistant panel 6 to the brace element 9 at the joining end is performed using, for example, a high-strength bolt. The brace element 9 is embedded in the concrete forming the panel material 8 and integrated with the panel material 8. A pair of reinforcing wire mesh 11 and deformed steel bars are embedded in the panel material 8 with the brace element 9 interposed therebetween.

  Such an earthquake-resistant panel 6 is manufactured in advance at a factory, a site, or the like. For the production of the earthquake-resistant panel 6, for example, when the earthquake-resistant panel 6 is laid sideways and flat-formed, it is floated from the bottom of the mold sequentially in the mold, and one welded wire mesh 11 is disposed. Next, the brace element 9 is arranged to be supported from the bottom of the mold, and then the other welded wire mesh 11 and the like are arranged so as to float from the brace element 9, and the boxed mold is placed at the position where the joint 10 is formed. In this state, concrete may be placed in the formwork. In addition, stud bolts 12 are embedded in the earthquake-resistant panel 6 at appropriate intervals around the four circumferences. Of course, the manufacture of the earthquake-resistant panel 6 may be vertical.

  The earthquake-resistant panels 6 are joined to each other by using a metal fitting 13 that is disposed in the joint 10 and joins the joint ends to each other. The metal joint 13 is formed in a flat plate shape having a size extending over two joints 10 or four joints 10. A pair of joint hardware 13 is disposed so as to sandwich the joint ends of the respective earthquake-resistant panels 6 from the front and back, and the pair of joint hardware 13 are fastened with high-strength bolts via the joint ends, so that the adjacent earthquake resistance Panels 6 are joined together.

  When these seismic panels 6 used in combination are arranged in the frame 4, the upper end of the lower beam 3 a is placed on one edge facing the opening 7, which will be described later, across the upper and lower seismic panels 6. A vertical plate 15 at the opening made of a steel plate having a vertical height dimension extending over the beam lower end 2a is provided. The vertical plate 15 at the time of opening transmits a vertical component of an oblique axial force borne by the brace element 9. The vertical plate 15 at the time of opening is joined to the earthquake-resistant panel 6 by the stud bolts 12 embedded in the panel material 8 through the attachment plate 16.

  On the other hand, three edge edges facing the inner surface of the frame 4 are provided with steel plate adhesive plates 17 surrounding the seismic panels 6. These adhesive plates 17 are also joined to the earthquake resistant panel 6 by the stud bolts 12 of the panel material 8. Moreover, the joint part 10 joined by the joint 18 and the joint metal 13 which are gaps between the adjacent earthquake-resistant panels 6 is filled with non-shrink mortar.

  As described above, a plurality of earthquake-resistant panels 6 are arranged vertically and horizontally, and the integrated earthquake-resistant wall 5 is constructed. When the seismic panel 6 integrated in this way is arranged in the frame 4, an adhesive material such as an epoxy resin is injected between the adhesive plate 17 and the inner surface of the frame 4 to form an adhesive layer 19. The frame 4 (the left and right columns 1, the upper beam 2, and the lower beam 3) is joined by the adhesive layer 19.

  The seismic panel 6 assembled with such a configuration is arranged in the frame 4 so as to be close to the left and right columns 1, so that the seismic panel 6 is interposed between the seismic panels 6 in the frame 4. An opening 7 is formed by partitioning.

  By arranging the seismic panels 6 in combination so as to have a height dimension extending from the lower beam upper end 3a to the upper beam lower end 2a, the opening 7 formed between the seismic panels 6 is similarly provided in the lower beam upper end 3a. To the upper beam lower end 2a. Further, the opening vertical plate 15 is located at the edge of the earthquake-resistant panel 6 facing the opening 7, that is, at the left and right edges of the opening 7.

  A steel connection plate 20 is provided in the opening 7. The connecting plate 20 is provided at the upper edge of the opening 7 at the lower end 2a of the upper beam and the lower edge of the opening 7 at the upper end 3a of the lower beam. Each connecting plate 20 is joined to the upper beam 2 and the lower beam 3. Further, the connecting plate 20 is provided such that the left and right ends in the length direction are in contact with the vertical plates 15 on the left and right sides that are the left and right edges of the opening 7 from the lateral direction.

  Specifically, as shown in FIGS. 2 to 5, the connecting plate 20 disposed at the lower edge of the opening 7 is formed long along the left and right edges of the opening 7, and extends laterally to the lower beam upper end 3 a. A pair of the horizontal plate member 20a that is placed face down and joined to the left and right ends of the horizontal plate member 20a in the lengthwise direction of the vertical plate 15 at the opening of the opening 4 from the horizontal plate member 20a. A pair of plate-like plates 20b, which are formed in an approximately triangular shape and are joined to corner portions of the pressure-bearing plate member 20b and the horizontal plate member 20a so as to be positioned approximately at the center in the width direction of the plate members 20a and 20b. Rib material 20c. The horizontal plate 20a is preferably made as thin as possible in consideration of the passage through the opening 7.

  The structure of the connecting plate 20 disposed at the upper edge of the opening 7 is the same, but the horizontal plate 20a is disposed below the upper beam 2 and the bearing plate 20b is suspended downward in the height direction of the vertical plate 15 at the time of opening. Arranged.

  Since the connecting plate 20 is disposed between the left and right edges of the opening 7, the plate surfaces of the respective supporting plate members 20 b are in contact with the left and right opening vertical plates 15, respectively, and act from the opening vertical plates 15. The rib member 20c transmits the horizontal force received by the support plate 20b to the horizontal plate 20a, and the horizontal plate 20a receives the horizontal force applied from the support plate 20b and the rib member 20c. Is transmitted in the horizontal direction. These bearing plate members 20b, horizontal plate members 20a, and rib members 20c are welded together.

  The horizontal plate member 20a of the connecting plate 20 is formed with a hole 22 through which the construction anchor bolt 21 is inserted after preventing the buckling of the horizontal plate member 20a at an appropriate interval in the length direction. The post-installed anchor bolt 21 is driven on the upper beam 2 and the lower beam 3. The anchor is preferably an organic adhesive anchor 23 (see FIG. 5).

  Further, the bearing plate 20b of the connecting plate 20 is positioned on both sides of the rib member 20c, and a pair of insertion holes 24 through which ordinary bolts 25 for joining the bearing plate 20b to the vertical plate 15 at the time of opening are inserted. Is formed. These insertion holes 24 are formed as long holes along the vertical direction in order to allow the connection plate 20 to slide in the vertical direction with respect to the vertical plate 15 at the time of opening, whereby the connection plate 20 is formed at the left and right edges of the opening 7. Each of the vertical plates 15 at the time of opening is joined so as to be slidable in the vertical direction. In order to improve the slidability, a sliding material such as grease may be applied between the bearing plate 20b and the vertical plate 15 at the time of opening.

  In the connection plate 20 configured in this manner, an adhesive material such as an epoxy resin is injected between the upper beam lower end 2a and the lower beam upper end 3a, which are the inner surfaces of the frame 4, in the same manner as the earthquake resistant panel 6. Is formed and joined to the inner surface of the frame 4 by the adhesive layer 19.

  Next, the construction method of the earthquake-resistant frame structure concerning this embodiment is demonstrated using FIG. 6 and FIG. Pre-priming work includes removal of finishing material on frame 4, removal of weak surface parts and protrusions, removal of latencies, dirt, oil, etc., repair of cracked parts, repair of cross-sectional defects, and vertical accuracy of the frame. -Perform shaping to the horizontal accuracy, and finish on the inner surface of the frame 4 which is flat and strong, clean and dry. Thereby, the joining by the adhesive material of the frame 4 inner surface, the connection plate 20, and the earthquake-resistant panel 6 can be made favorable.

  Next, post-construction for preventing the earthquake-resistant panel 6 from falling out of the plane toward the upper beam lower end 2a and the lower beam upper end 3a forming the inner surface of the frame 4 at the installation position of the earthquake-resistant panel 6 and the installation position of the connecting plate 20 The anchor 26 and the post-construction anchor 23 for buckling prevention are driven (see (a) in FIG. 6).

  Next, the connecting plate 20 disposed at the position where the opening 7 is formed is connected to the post-construction anchor 23 for buckling prevention, and is floated and fixed to the upper edge and the lower edge of the opening 7. At this time, if necessary, a sliding material may be applied to the bearing plate 20b.

  Thereafter, or in parallel with this, a temporary member 27 such as a temporary angle is used, the vertical plate 15 at the opening is also incorporated, and the pair of upper and lower earthquake-resistant panels 6 are assembled and integrated.

  Next, a set of a pair of upper and lower earthquake-resistant panels 6 (PCa plates in FIG. 7) that have been grounded is sequentially built between the opening 7 and the pillar 1 from the opening 7 toward the pillar 1. . At this time, the seismic panel 6 is fixed to the post-construction anchor 26 for preventing out-of-plane collapse with bolts, and a camber 28 for floating the seismic panel 6 between the seismic panel 6 and the inner surface of the frame 4 is inserted. A gap for forming the adhesive layer 19 is secured.

  The vertical plate 15 at the time of opening and the bearing plate 20b of the connecting plate 20 are fastened with a normal bolt 25. Adjacent earthquake-resistant panels 6 are temporarily joined with high-strength bolts through the joint hardware 13. As described above, the earthquake-resistant panel 6 is temporarily fixed in the frame 4 (see (b) to (d) in FIG. 6). When all the seismic panels 6 are temporarily fixed, the high-strength bolt (HTB) is finally tightened (see (e) in FIG. 6).

  Next, the temporary material 27 and the camber 28 are removed (see (f) in FIG. 6). At this time, the positioning of the connecting plate 20 and the earthquake-resistant panel 6 in the frame 4 is ensured by the post-construction anchors 23 and 26. Thereafter, the joint portion 18 and the joint portion 10 are filled with non-shrink mortar (see (g) in FIG. 6).

  Finally, an adhesive is injected as an outer peripheral seal between the surface of the pair of left and right columns 1 and the pair of upper and lower upper beam lower ends 2a and lower beam upper end 3a, which are the inner surfaces of the frame 4, and the earthquake-resistant panel 6 and the connecting plate 20. Thus, the adhesive layer 19 is formed (see (h) in FIG. 6). After that, it is cured and cured, and the construction is completed.

  In the earthquake-resistant frame structure according to the present embodiment, the horizontal stress F such as the earthquake force applied to the frame 4 is basically received by the earthquake-resistant panel 6. As shown in FIG. 8, the seismic panel 6 that receives the horizontal stress F generates an oblique axial force C along the brace element 9, and the horizontal force H that is a horizontal component of the oblique axial force C is It acts on the upper and lower connecting plates 20 directly from the adhesive layer 19 between the earthquake-resistant panel 6 and the inner surface of the frame 4 or through the vertical plate 15 at the time of opening.

  Each of the upper and lower connecting plates 20 receives the horizontal force H by the bearing plate 20b and transmits it to the horizontal plate 20a via the rib member 20c. The horizontal plate 20a is disposed between the left and right edges of the opening 7 and transmits the horizontal force H to the seismic panel 6 on the opposite side. Thereby, even if the opening part 7 is formed in the frame 4, the proof strength of the earthquake-resistant panel 6 can be exhibited effectively and high earthquake-proof reinforcement performance can be ensured.

  Further, even if a slip failure Z occurs in the adhesive layer 19 due to the large horizontal stress F, the horizontal movement of the earthquake-resistant panel 6 can be prevented or suppressed by the connecting plate 20, thereby reducing the horizontal strength of the frame 4. This can be prevented, and the structural strength required as an earthquake-resistant structure built in the frame 4 in which the opening 7 is formed can be ensured.

  In addition, the connecting plate 20 is a separate part from the seismic panel 6 and can be installed and installed in the opening 7 separately from the installation of the seismic panel 6. Construction and high dimensional accuracy are not required, and construction can be performed easily and appropriately using the earthquake-resistant panel 6 made of PCa.

  Further, since the connecting plate 20 is provided not only at the lower edge portion of the opening portion 7 but also at the upper edge portion, the structure directly above the opening portion in the background art is a low wall part made of concrete, so It is possible to sufficiently and reliably ensure the transmission action of the horizontal force H in the frame 4, and to secure the structural strength necessary as an earthquake-resistant structure constructed in the frame 4 in which the opening 7 is formed.

  Since the earthquake-resistant panel 6 includes the brace element 9, the horizontal stress F can be appropriately transmitted as the oblique axial force C to be applied to the connection plate 20, and the horizontal force H of the connection plate 20 is transmitted. The effect can be exhibited appropriately.

  Since the horizontal plate member 20a of the connecting plate 20 is joined to the upper beam 2 and the lower beam 3 by the buckling prevention anchor 23, the horizontal plate member 20a can be buckled and stiffened. The ultimate compressive strength of 20 can be ensured high, and even a large horizontal force H can be appropriately transmitted. Thereby, the thickness of the horizontal plate material 20a can be set further thinner, and a large area of the opening 7 can be secured.

  Since the connecting plate 20 is joined to the vertical plate 15 at the time of opening by the long hole-like insertion hole 24 and the normal bolt 25 so as to be slidable in the vertical direction, both of them can be pin-joined. The moment other than the axial force in the horizontal direction can be prevented from acting, and the connecting plate 20 can exhibit a predetermined performance.

  The connecting plate 20 is in contact with the left and right edges of the opening 7 and is provided between a pair of supporting plate members 20b that receive the horizontal force H in the frame 4, and the horizontal force H And a rib member 20c interposed between the plate surface of the horizontal plate member 20a and the plate surface of the bearing plate member 20b and transmitting the horizontal force H from the bearing plate member 20b to the horizontal plate member 20a. Since it is configured, the structure is simple and can be easily manufactured, and the transmission action can be surely exhibited.

  Moreover, the construction method of the seismic frame structure according to the present embodiment is basically arranged at a position where the opening 7 of the frame 4 is formed, and the connecting plate 20 is floated on the lower beam 3 and the upper beam 2 from these. Temporarily fixing and floating the earthquake-resistant panel 6 between the connection plate 20 and the pillar 1 from the inner surface of the frame 4, between the connection plate 20 and the lower beam 3 and the upper beam 2, and the earthquake-resistant panel 6 And the inner surface of the frame 4 can be constructed by a process of filling an adhesive, and in particular, the connecting plate 20 can be installed separately from the seismic panel 6. Unlikely, it is possible to construct an earthquake-resistant frame structure including the opening 7 easily and smoothly.

  In the above embodiment, the case where the same number of seismic panels 6 are arranged on both sides of the opening 7 and the seismic frame structure is symmetrical is described as an example. However, as shown in FIG. Needless to say, the number of panels 6 may be varied to be asymmetrical.

  9 and 10 show an earthquake-resistant frame structure and its construction method in which the opening 7 partitioned in the frame 4 by the earthquake-resistant panel 6 is moved to one side of the frame 4 and arranged adjacent to the pillar 1. An embodiment is shown.

  Even in this case, the connecting plate 20 is joined to the lower beam 3 and the upper beam 2 at the upper edge and the lower edge of the opening 7, respectively, and the horizontal force H in the frame 4 is applied to the opening 7. Is transmitted between the left and right edges. Further, the bearing plate 20b of the connecting plate 20 is joined to the surface of the column 1 facing the opening 7 by a long hole-like insertion hole 24 and a normal bolt 25 inserted therethrough so as to be slidable in the vertical direction. The

  In this case, the horizontal stress F such as seismic force applied to the frame 4 is basically received by the earthquake resistant panel 6. The horizontal force H of the horizontal stress F received by the earthquake resistant panel 6 is input to the upper and lower connecting plates 20. As in the case of the above embodiment, the upper and lower connecting plates 20 receive the horizontal force H with the bearing plate 20b and transmit it to the horizontal plate 20a via the rib member 20c. The horizontal plate 20 a is disposed between the left and right edges of the opening 7 and transmits the horizontal force H to the column 1.

  Thereby, even if the opening part 7 is formed in the frame 4, the proof strength of the earthquake-resistant panel 6 can be exhibited effectively and high earthquake-proof reinforcement performance can be ensured.

  Further, even if the sliding failure Z occurs in the adhesive layer 19 due to the large horizontal force H and the earthquake-resistant panel 6 tries to move in the horizontal direction, the connecting plate 20 takes a reaction force on the column 1 to prevent the movement or Accordingly, it is possible to prevent the horizontal proof stress of the frame 4 from being lowered, and it is possible to secure the structural strength necessary as an earthquake resistant structure built in the frame 4 in which the opening 7 is formed.

  Therefore, even in such an embodiment, it is a matter of course that the same operational effects as the above-described embodiment can be obtained.

  The construction method is also substantially the same as that of the above-described embodiment except that the connection plate 20 is installed adjacent to the pillar 1 and that the set of the upper and lower pair of earthquake-resistant panels 6 that are assembled is an opening. 7 and the pillar 1 separated from the opening 7 are sequentially built. Even in such an embodiment, it is a matter of course that the same operational effects as the construction method according to the above embodiment can be obtained.

  In the above embodiment, the case where the connection plate 20 is installed first and the earthquake-resistant panel 6 is installed later has been described as an example, but the connection plate 20 may be installed later. Of course.

  Although the said embodiment demonstrated the existing structure object, it is needless to say that you may apply to a new structure. A plurality of openings 7 may be provided in the single frame 4, and the connection plate 20 may be provided in each of the openings 7.

  In the above embodiment, the case where the earthquake-resistant panel 6 and the connecting plate 20 are joined to the inner surface of the frame 4 with the adhesive layer 19 has been described as an example, but other joining methods may be used. In the above-described embodiment, the case where the earthquake-resistant wall 5 is configured by arranging a plurality of earthquake-resistant panels 6 has been described as an example, but a single earthquake-resistant panel is provided on each column 1 side with the opening 7 as a boundary. 6 may be provided.

  Further, the upper end of the lower beam in the claims and the detailed description of the present invention includes both the case where the slab is constructed on the lower beam upper end 3a and the case where the slab is constructed flush with the lower beam upper end 3a. Therefore, the connecting plate 20 may be joined to the lower beam 3 via the slab or directly to the lower beam 3. Accordingly, the inner surface of the frame 4 also includes both the case of the lower beam upper end 3a and the case of the slab upper end.

  Further, the temporary fixing of the connecting plate 20 and the installation of the earthquake-resistant panel 6 in the construction method may be preceded or may be performed simultaneously.
