Description

  The present invention relates to a construction method for a seismic wall using a precast concrete block (PCa block) for a seismic wall and the precast concrete block for the seismic wall.

  In particular, the present invention has a through-hole capable of passing vertical and horizontal bars inside a precast concrete main body, and is composed of columns and beams while passing the vertical and horizontal bars through the through-hole. The present invention relates to a precast concrete block for a seismic wall, a seismic wall, and a seismic wall construction method that can be incorporated inside a frame (column beam structure).

  For the purpose of seismic reinforcement of buildings made of reinforced concrete or steel-framed reinforced concrete, the building may be reinforced by newly installing reinforced concrete seismic walls in the frame structure composed of columns and beams.

  In order to increase the above-mentioned seismic walls, it has been widely practiced to place reinforcements at the site, install formwork, and place concrete. However, this method of placing reinforcement, formwork and concrete on site (concrete placement method on site) is time consuming and it is difficult to complete the construction in a short period of time while using the building. .

  This on-site concrete placement method is also used for so-called roughening or fraying, in which the seismic wall is integrated with the structure of the existing building, so-called roughening or fraying that creates unevenness on the columns and beams of the existing building. Had to work such as hammering, and had a problem of generating a great deal of noise and vibration.

  On the other hand, the technique which adhere | attaches the steel frame material which provided the anchor reinforcement | protrusion to the structure of the existing building with an epoxy resin was proposed (patent 39392401).

  The technology proposed by this Japanese Patent No. 3992401 solved the problems of the above-mentioned roughening and anchoring noise and vibration by a method of adhering a steel frame material to a structure of an existing building.

  However, the technology proposed by this patent 3992401 also has a process of placing bars on the site, installing a formwork and placing concrete, so it is difficult to complete the construction in a short period of time while using the building. there were.

  On the other hand, in order to reduce the on-site formwork creation and concrete placement work, a method of building a seismic wall by stacking concrete blocks on-site instead of the concrete placement method on-site has also been proposed. (For example, Japanese Patent Laid-Open No. 2000-257189, Japanese Patent No. 3975938).

  JP-A-2000-257189 uses a directional formwork concrete block divided into the length of a seismic wall for a formwork concrete block arranged in a partial section above the height direction of the seismic wall. Therefore, the technology which can pile up a formwork concrete block is disclosed, passing a vertical line to the frame of an upper floor.

  On the other hand, in Japanese Patent No. 3975938, a steel frame member with anchor bars protruding inside the opening of the column beam frame is bonded with an adhesive, and the vertical bars are joined to the anchor bars on the lower inner surface of the steel frame member. A seismic reinforcement method is disclosed in which concrete blocks are arranged and transverse bars joined to the inner surface of the steel frame member are arranged at the upper and lower joints of each concrete block.

Patent No. 3992401 JP 2000-257189 A Japanese Patent No. 3975938

  The present invention employs a method of stacking concrete blocks in order to reduce work on site and shorten the construction period.

  In this regard, Japanese Patent Application Laid-Open No. 2000-257189 and Japanese Patent No. 3975938 also disclose a method of stacking concrete blocks.

  However, neither the technique of Japanese Patent Laid-Open No. 2000-257189 nor the technique of Japanese Patent No. 3975938 has been able to pass the reinforcing reinforcing bar horizontal bars through the concrete body of the concrete block.

  Specifically, in the technique disclosed in Japanese Patent Laid-Open No. 2000-257189, horizontal stripes are arranged every time a concrete block is stacked (paragraph 0025).

  On the other hand, in the technology of Japanese Patent No. 3975938, when a block of concrete is piled up, a concrete block groove is used, and a horizontal anchor bar is screwed into a long nut so as to fit in the groove. Overlap and fix with a wire etc. and grout the horizontal streak with concrete in the groove of the block.

  By the way, when the horizontal streak is arranged at the joint between the upper and lower concrete blocks, there is a limit to the force for connecting the left and right concrete blocks.

  In other words, when building a seismic wall by stacking concrete blocks, if the horizontal bars can be passed not only through the vertical bars but also inside the concrete body of the concrete blocks, the integrity of the seismic wall is improved and the strength is increased. It is clear that it will increase.

  However, when a concrete block is built inside a rigid frame composed of columns and beams, the left and right ends of the earthquake-resistant wall are in contact with the columns, so it is difficult to penetrate the concrete block main body with horizontal bars.

  Of course, it is conceivable to arrange the concrete block so as to leave a gap for joining the horizontal streak between the column and the concrete block, but there is a problem in that the integrity of the column and the earthquake-resistant wall is lowered.

  For this reason, as in the technique disclosed in Japanese Patent Laid-Open No. 2000-257189 and Japanese Patent No. 3975938, a horizontal streak is disposed on the upper end surface of the concrete block every time the concrete block is assembled one stage. However, as described above, the connection of the concrete blocks in the lateral direction of the seismic wall is weakened and the integrity is lowered by doing so.

  Therefore, the problem to be solved by the present invention is that a precast concrete main body has a through hole through which the vertical and horizontal bars can pass, and a column while passing the vertical and horizontal bars through the through hole. To provide a precast concrete block for seismic walls, a seismic wall, and a seismic wall construction method that can be built inside a ramen frame composed of steel and beams, and can easily construct a seismic wall with low noise is there.

  FIG. 1 shows a precast concrete block for earthquake resistant walls according to an embodiment of the present invention.

  The precast concrete block 1 for a earthquake resistant wall according to the present embodiment has a rectangular concrete body 2 as a whole. The shape of the concrete main body 2 is not limited to a rectangular body, and may have a hexagonal shape as viewed from the front, for example. The concrete body 2 is precast at the factory and is made of solid concrete.

  The code | symbol 2a has shown the front or back in the state in which the concrete main body 2 was used for the earthquake-resistant wall. Reference numeral 2b indicates an upper surface in a state where the concrete main body 2 is used as a seismic wall. Moreover, the code | symbol 2c has shown the side surface (the both ends of the horizontal direction of a seismic wall) in the state in which the concrete main body 2 was used for the seismic wall.

  The longitudinal muscle through holes 3 and 4 according to the present embodiment have an expanded portion that receives the dripping of the adhesive at the upper portion, but the expanded portion is not essential for the longitudinal muscle through hole. Moreover, the shape of the hole of the vertical muscle through-holes 3 and 4 is arbitrary.

  The vertical muscle through holes 3 and 4 have an inner diameter through which two vertical muscles can pass. The inner diameter of the vertical muscle through-holes 3 and 4 is not so large that it is not difficult to insert two vertical muscles, and is not so large that the two vertical muscles swing around in the hole.

  Although the horizontal reinforcement through-hole 5 according to the present embodiment has an expanded portion that makes it easier to pass a reinforcing bar at the end, the expanded portion is not essential. The shape of the hole of the transverse muscle through hole 5 is arbitrary. You may provide the expansion part which makes it easy to let a reinforcing bar pass to an edge part.

  The transverse muscle through hole 5 has an inner diameter through which two transverse muscles can pass. The inner diameter of the transverse muscle through-hole 5 is appropriately determined so as not to be difficult to penetrate two transverse muscles and not so large that the two transverse muscles swing around in the hole.

  In the present embodiment, the longitudinal muscle through-hole and the transverse muscle through-hole pass through the pair of sliding transverse muscles and immovable transverse muscles, or the pair of sliding longitudinal muscles and immovable longitudinal muscles. The inner diameter of the two vertical bar penetration holes is larger than it is not difficult to penetrate the two vertical bars, and is not so large that the two bars swing around in the hole. As appropriate. In the following description of the embodiment, a precast concrete block for a seismic wall in which a longitudinal reinforcement through-hole and a transverse reinforcement through-hole pass two rebars respectively and a construction method thereof will be described.

The number of cotters is also arbitrary. Furthermore, in the present invention, the cotter can be omitted because the integrity is enhanced through the vertical and horizontal bars inside the concrete body.

But you can. Further, although the sheath tube 8 in the present embodiment uses a spiral corrugated tube, a concentric corrugated tube may be used. That is, the “corrugated tube” in this specification includes both a spiral corrugated tube and a concentric corrugated tube. Further, instead of a corrugated tube, a bellows tube may be used.

  The sheath tube 8 only needs to hold the reinforcing bars inside and to improve the adhesiveness between the grout material filled in the sheath tube 8 and the concrete of the concrete main body 2. It may be a tubular shape having irregularities and may be arbitrarily used by those skilled in the art.

  The sheath tube 8 can be omitted if the adhesion between the grout material filled in the vertical reinforcement through holes 3 and 4 and the concrete of the concrete main body 2 is not particularly required.

  The inner diameter of the sheath tube 8, that is, the inner diameter of the small-diameter portion, is inserted through two longitudinal muscles (a plurality of accessory muscles including accessory muscles when accessory muscles are used) as described for the longitudinal muscle through holes 3 and 4. The size is not so difficult, and it is determined appropriately so that the two vertical bars (multiple including the additional muscles when using additional muscles) are not so large as to swing around in the hole. .

Also, the sheath tube 9 has arbitrary irregularities on the inside and outside of the concrete body 2 to enhance the adhesion to the concrete. It may be tubular, and includes a spiral corrugated tube, a concentric corrugated tube, and a bellows-shaped tube.

  The sheath tube 9 can be omitted when the adhesion between the grout material filled in the transverse bar penetration hole 5 and the concrete of the concrete main body 2 is not particularly required.

  The inner diameter of the sheath tube 9, that is, the inner diameter of the small-diameter portion, is larger than the extent that it is not difficult to insert two transverse muscles (a plurality (for example, three) when using accessory muscles), It is determined appropriately so that two (or a plurality of accessory muscles including accessory muscles when using accessory muscles) are not so large as to swing around in the hole.

  The joining nut 12 and the joining metal fitting 13 are provided in advance at the portion where the vertical and horizontal stripes abut.

  Next, as shown in FIG. 6, the lowermost precast concrete block for the earthquake resistant wall in the left half of the earthquake resistant wall is disposed.

  Specifically, a predetermined number (four in the example of FIG. 6) of precast concrete blocks 1 for earthquake-resistant walls are arranged from the left side in the lateral direction inside the steel frame member 14, and the arrangement of the precast concrete blocks 1 for earthquake-resistant walls is arranged. A horizontal bar 16 is inserted into the horizontal bar through-hole and is screwed to the joining nut 12 of the steel frame member 14. The horizontal bar 16 screwed to the joining nut 12 is used as an immobile horizontal bar 16a, and a spare horizontal bar 16 is inserted as a sliding horizontal bar 16b into the horizontal bar through hole.

  Here, the immovable transverse bar means the transverse bar placed at the position, and the sliding lateral bar means that when the precast concrete block for the earthquake-resistant wall is additionally arranged, the precast for the earthquake-resistant wall additionally arranged by sliding. The horizontal stripe inserted into the horizontal reinforcement through hole of the concrete block 1 is said. Accordingly, when the sliding horizontal stripe 16b cannot be slid further because the continuity as the horizontal stripe is reduced, the sliding horizontal stripe 16b is placed at that position and a new sliding horizontal stripe 16b is inserted as the immovable horizontal stripe 16a.

  Next, the precast concrete block for the bottommost earthquake-resistant wall in the right half of the earthquake-resistant wall is disposed.

  FIG. 7 shows a single precast concrete block 1 for the earthquake-resistant wall in the lowermost half of the right half of the earthquake-resistant wall.

  After arranging the lowermost precast concrete block 1 for the earthquake-resistant wall in the right half of the earthquake-resistant wall, slide the sliding horizontal reinforcement 16b inserted in the transverse reinforcement through-hole of the precast concrete block for the earthquake-resistant wall in the right half to the right Insert into the horizontal bar through-hole of the precast concrete block for half of the shear wall.

  In the example of FIG. 7, for the sake of simplicity, the case where there are two transverse bars 16 is shown. When the four precast concrete blocks 1 for the left half are arranged, the four precast concrete for the right half are installed. It can be said that the blocks 1 are arranged from the left side. However, the present invention forms a seismic wall on both sides adjacent to the pillars 10 on both sides, and finally, at a location from the center away from the pillars 10 on both sides. Thus, the horizontal bars 16 are connected to each other without incorporating the precast concrete block 1 for the earthquake resistant wall. For this reason, when precast concrete blocks for seismic walls are arranged “from both sides inside the steel frame material” in this specification, the precast concrete for seismic walls in the left and right parts of the seismic wall Regardless of the arrangement order of the blocks, in short, the left part and the right part are formed first with respect to the central part of the earthquake resistant wall. That is, “a predetermined number of precast concrete blocks for earthquake-resistant walls are arranged from both lateral sides inside the steel frame member” according to the present invention means that a predetermined number of blocks of the precast concrete blocks for earthquake-resistant walls (for example, FIG. The left half and the right half) are arranged from both sides of the inside of the steel frame material, and are individually seismic resistant within a predetermined number of precast concrete blocks for the seismic wall (eg left half and right half in FIG. 7). It includes any case where the precast concrete block 1 for walls is disposed.

  Moreover, in the example of FIGS. 6-13, although the case where a single horizontal bar 16 is sufficient for each of the left half and the right half of the precast concrete block 1 for the earthquake resistant wall is described, The precast concrete block 1 for earthquake resistant walls is additionally provided.

  That is, the precast concrete block 1 for the earthquake resistant wall is additionally arranged in the lateral direction from the precast concrete block for the earthquake resistant wall in the left half of FIGS. When the immovable transverse bar 16a and the sliding transverse bar 16b reach an overlapped portion of a predetermined length through the through hole of the precast concrete block 1 for earthquake resistant wall, the sliding horizontal bar 16b is not pulled out any more and fixed as the immovable horizontal bar 16a. Then, the precast concrete block 1 for the earthquake-resistant wall may be additionally arranged in the lateral direction while newly inserting the spare horizontal bar 16 as the sliding horizontal bar 16b into the horizontal bar through hole.

  In this way, the precast concrete blocks 1 for earthquake-resistant walls are arranged from both lateral sides inside the steel frame member 14, and the leading portion of the row of the precast concrete blocks 1 for earthquake-resistant walls has a predetermined distance (for example, precast concrete for earthquake-resistant walls). When approaching a distance equal to or less than the width of one block), the sliding horizontal stripes 16b of the precast concrete blocks 1 on both sides are overlapped with each other without incorporating the precast concrete block 1 for the earthquake resistant wall any more. An overlapping portion of a predetermined length is formed or connected with a joint fitting.

  FIG. 8 shows the four precast concrete blocks 1 for the seismic wall in the left half, and the four precast concrete blocks 1 for the seismic wall in the right half of the precast concrete block 1 for the seismic wall in the lower three stages of the seismic wall. Are shown, and the horizontal bars 16 are connected to each other without incorporating the precast concrete block 1 for earthquake resistant walls at the center.

  The precast concrete block 1 for earthquake-resistant wall is arrange | positioned also to the vertical direction with the horizontal direction installation process of the precast concrete block 1 for earthquake-resistant walls.

  FIG. 8 shows a state in which three stages of precast concrete blocks 1 for earthquake resistant walls are stacked in the vertical direction.

  Any known joining means including an adhesive or mortar cement may be used for joining between the steps of the precast concrete block 1 for earthquake resistant walls.

  9-11 has shown the vertical direction stacking process of the precast concrete block 1 for earthquake-resistant walls.

  In the vertical stacking process of the precast concrete blocks 1 for earthquake-resistant walls, a predetermined number (three or four in the example of FIGS. 9-11) of the precast concrete blocks 1 for earthquake-resistant walls is stacked in the vertical direction inside the steel frame member 14. In addition, one vertical bar 17 is inserted into the vertical bar through-hole of the precast concrete block 1 for the earthquake-resistant wall and screwed to the joining nut 12 on the lower inner surface of the steel frame member 14 to form an immovable vertical bar 17a. One spare vertical bar 17 is inserted into the vertical bar through hole as a sliding vertical bar 17b.

  The meanings of “non-moving” and “sliding” of the non-moving vertical bars 17a and the sliding vertical bars 17b are the same as those of the horizontal bars.

  Next, the precast concrete block 1 for the earthquake-resistant wall is additionally stacked in the vertical direction according to the height of the earthquake-resistant wall, and the vertical reinforcement through-holes of the precast concrete block for the earthquake-resistant wall are additionally stacked by pulling out the sliding vertical bars 17b. (See FIG. 11).

  The raised sliding vertical bars 17b are locked by a locking metal fitting 18 as shown in FIG. 11, and are prevented from falling into the vertical bar through holes.

  In the example of FIGS. 9-11, two vertical bars 17 are sufficient. However, when there are three or more vertical bars 17, when the fixed vertical bars 17a and the sliding vertical bars reach an overlapping portion of a predetermined length, the sliding lines 17 The moving vertical bars 17b are not pulled out any more and are locked by the locking metal fittings to be fixed as the stationary vertical bars 17a, and a spare vertical bar 17 is newly inserted into the vertical bar through hole as the sliding vertical bar 17b. However, additional precast concrete blocks 1 for earthquake resistant walls will be stacked.

  In addition, in FIG. 9-11, the code | symbol 19 has shown the coupling metal fitting for joining the horizontal stripe 16 instead of the overlap part of predetermined length.

  FIG. 12 shows that when the upper end of the piled precast concrete block 1 for earthquake-resistant wall approaches a predetermined distance to the upper inner surface of the steel frame member 14, for example, approaching a distance where no more precast concrete block 1 for earthquake-resistant wall can be incorporated. Shows when.

  When the upper end of the piled precast concrete block 1 for the earthquake-resistant wall approaches a predetermined distance to the upper inner surface of the steel frame member 14, as shown in FIG. 13, without further incorporating the precast concrete block 1 for the earthquake-resistant wall, The sliding vertical bars 17b are welded to the joining metal fitting 13 on the upper inner surface of the steel frame member 14. As a method of joining the sliding longitudinal bars 17b to the upper inner surface of the steel frame member 14, it may be screwed to a joining nut or an overlapping part of a predetermined length with the anchor bars may be formed.

  In the state of FIG. 12, the grout material is filled into the horizontal reinforcement through-holes of the precast concrete blocks 1 for earthquake-resistant walls in each stage and the vertical reinforcement through-holes of the precast concrete blocks 1 for earthquake-resistant walls in each vertical row.

  FIG. 13 shows a state in which the horizontal placement process, the vertical stacking process, and the grout filling process of the through holes are completed, and the final concrete placing or finishing process by filling the grout material is performed. Is shown.

  That is, after the precast concrete block 1 for earthquake-resistant wall is incorporated inside the column beam frame by appropriately combining the horizontal arrangement step and the vertical stacking step of the precast concrete block for the earthquake-resistant wall, the horizontal arrangement step and the vertical direction In the stacking process, the precast concrete block for the earthquake-resistant wall is not incorporated, that is, the bar is placed in the hatched portion in FIG. Alternatively, the grout material may be filled in the mold.

  After placing concrete or filling grout material, remove the formwork and complete the construction.

  The method of joining the horizontal and vertical bars and the steel frame material can be combined as appropriate.

  14 and 15 show combinations of joining methods of the horizontal bars 16 and the steel frame material. The same can be said for the vertical bars.

  In the joining method of FIG. 14, anchor bars 20 project from a steel frame member (not shown), and the horizontal bars 16 and the anchor bars 20 are overlapped with each other by a predetermined length to form an overlapping portion 21. This is an example.

  The overlapping portion 21 having a predetermined length can be used for joining the horizontal stripes 16 or the vertical stripes 17 to each other.

  The joining method of FIG. 15 is an example in which a joining nut 12 is provided on a steel frame material (not shown), the transverse bars 16 are screwed to the joining nut 12 and joined, and the transverse bars 16 are joined together by a butted joint fitting 22. is there.

  As a joining method with the steel frame material, a joining method by welding can be appropriately used.

  Next, a different earthquake resistant wall construction method of the present invention will be described with reference to FIGS.

  In the construction method of FIG. 6-13, when the precast concrete block 1 for earthquake-resistant wall is piled up while pulling out the sliding vertical bars 17b, the pulled sliding vertical bars 17b are prevented from falling into the vertical bar through holes. The locking bracket 18 is used.

  On the other hand, in the construction method of FIGS. 16-18, the pulling string is used without using the locking metal fitting.

  16-18 shows the vertical stacking process of the precast concrete blocks for earthquake resistant walls corresponding to the process of FIGS. 9-11 in all the processes. For ease of understanding, the same parts as those in FIGS.

  FIG. 16 shows that when the precast concrete block 1 for a seismic wall is further stacked, the head of the vertical bar 17 reaches the height at which the head of the precast concrete block 1 for the seismic wall 1 is immersed in the vertical bar through-holes 3 and 4. The place where the precast concrete block 1 was piled up is shown.

  As shown in FIG. 16, in this construction method, a pulling string 23 is tied to the sliding longitudinal bar 17b. The lifting string 23 is preferably made of a water-resistant material such as polyvinyl and is strong enough to pull up the sliding vertical bar 17b.

  FIG. 17 shows a state where the precast concrete blocks 1 for earthquake resistant walls are stacked one stage from the state of FIG.

  In this construction method, when the precast concrete block 1 for a earthquake resistant wall is piled up, it is piled up after passing through the pulling cords 23 in the longitudinal through holes 3 and 4 of the precast concrete block 1 for the earthquake resistant wall.

  That is, when the precast concrete block 1 for earthquake-resistant walls is stacked one stage from the state of FIG. 16, as shown in FIG. 17, the pull-up string 23 is a vertical reinforcement through-hole 3 of the precast concrete block 1 for earthquake-resistant walls stacked. 4 is led out to the outside from the longitudinal reinforcement through-holes 3 and 4 of the precast concrete block 1 for the uppermost earthquake-resistant wall.

  Thereafter, the above-mentioned vertical stacking process of the precast concrete block for the shear wall is repeated, and the precast concrete wall precast for the shear wall is so high that the precast concrete block 1 for the seismic wall cannot be incorporated any more in relation to the height of the beam 11 and the steel frame 14. Stack up concrete blocks 1.

  FIG. 18 shows a process after the precast concrete blocks 1 for earthquake-resistant walls have been stacked up to a height at which the precast concrete blocks 1 for earthquake-resistant walls cannot be incorporated any more in relation to the heights of the beams 11 and the steel frame members 14.

  According to the present construction method, as shown in the several sliding vertical bars 17b on the right side of FIG. 18, the sliding vertical bars 17b have the lifting string 23 tied to the head thereof, and the precast for the uppermost earthquake-resistant wall. The concrete block 1 is led out to the outside through the vertical reinforcement through holes 3 and 4.

  Accordingly, the vertical sliding bars 17b can be pulled up by pulling up the pulling cords 23, and the vertical sliding bars 17b are pulled up and welded to the upper inner surface of the steel frame member 14.

  As described above, as a method of joining the sliding longitudinal bars 17b to the upper inner surface of the steel frame member 14, it is possible to form an overlapped part of a predetermined length with the threaded or anchor bars in addition to welding. .

  After all the sliding vertical bars 17b are joined to the upper inner surface of the steel frame member 14, the grout material is filled into the horizontal bar through-holes of the precast concrete block 1 for the earthquake-resistant wall at each stage.

  After the through hole grout filling step, the space in which the precast concrete block 1 for the earthquake resistant wall is not incorporated is finished by concrete placement or grout filling.

  Finally, the work is completed by removing the formwork for placing concrete or filling the grout material.

  In addition, in the horizontal arrangement step, the horizontal reinforcement through-hole 5 of the precast concrete block 1 for earthquake-resistant wall that is additionally arranged by additionally arranging the precast concrete block 1 for earthquake-resistant wall in the horizontal direction and pulling out the sliding horizontal reinforcement 16b. When the fixed transverse muscle 16a and the sliding transverse muscle 16b reach the overlapping portion of a predetermined length, the sliding transverse muscle 16b is placed as the stationary transverse muscle 16a without being pulled out any more, and the spare one transverse muscle is newly slid. It is possible to form a seismic wall having an arbitrary width by inserting the precast concrete block for the seismic wall in the lateral direction by inserting it into the lateral muscle through-hole 5 as the lateral muscle 16b.

  Further, in the vertical stacking process, the seismic wall having an arbitrary height can be formed by using both the locking metal fitting 18 and the lifting string 23.

  According to the present invention, the steel frame material is bonded to the column beam frame of the existing building, and the precast concrete block for the earthquake-resistant wall is incorporated in the steel frame material, so the work of breaking the column beam of the existing building, There is no need to perform anchoring work. Therefore, the problem of noise and vibration does not occur. In addition, most of the seismic walls are constructed with precast concrete blocks for seismic walls, and the finishing process by the last concrete placement or grout filling is very limited and it is easy to place concrete or grout filling. Since it has a shape, it is possible to complete the work in a short period of time with less burden on the construction site. In addition, since the block product process can be stopped at an arbitrary stage, it can be performed in an intermittent process such as only on holidays or only at night while using the building.

  In addition, as described above, according to the present invention, the precast concrete block for the earthquake resistant wall can be incorporated inside the column beam frame in the limited space while passing the vertical and horizontal bars inside the precast concrete main body. it can.

  That is, according to the present invention, the precast concrete blocks for the earthquake-resistant wall arranged in the transverse direction in the state where the earthquake-resistant wall is constructed can arrange the horizontal stripes through the transverse muscle through-holes, and Both ends of the threaded horizontal bars can be joined to the steel frame material.

  Thereby, the integrity of the precast concrete block for the seismic wall in the lateral direction, that is, the horizontal direction of the seismic wall is extremely high, and the seismic wall having extremely high strength can be obtained.

  Moreover, a vertical bar can be arrange | positioned through the vertical bar through-hole of the precast concrete block for earthquake-resistant walls also in the vertical direction, and the upper and lower ends of the vertical bar can be joined to the steel frame material.

  Thereby, the integrity of the precast concrete block for the earthquake resistant wall is extremely high, and the earthquake resistant wall having high strength and extremely high fall resistance strength can be obtained.

  Moreover, according to the precast concrete block for earthquake-resistant walls of this invention, a strong joint can be formed by forming the overlap part of predetermined length in the inside of a through-hole in both a vertical bar and a horizontal bar.

  Both the horizontal and vertical reinforcement through-holes of the precast concrete block for earthquake-resistant walls of the present invention are pre-cast in a state of high quality control at the factory, so there is no defect such as insufficient filling of concrete and extremely high density Since this through hole has an inner diameter that allows two vertical and horizontal bars (multiple including the accessory muscles to be used), the overlapping part In this way, the reinforcing bars do not overlap with each other when they are close to each other.

  Thereby, it is possible to have a joint with extremely high reliability by filling the grout with a predetermined length of reinforcing bars in the through hole.

  Furthermore, if a sheath tube is used, due to changes in the diameter of the sheath tube, the integrity of the main body of the precast concrete block for the earthquake-resistant wall and the grout material filled in the through-hole becomes high, and a highly reliable earthquake-resistant wall can be obtained. Can be obtained.

  When the sheath tube is made of metal, it has an effect of holding the reinforcing bar inside thereof, and can prevent the reinforcing bars from separating from each other.

  According to the precast concrete block for a seismic wall according to the present invention provided with cotters on the upper and lower surfaces of the concrete body, the cotter can prevent the lateral displacement of the precast concrete block adjacent to the top and bottom, and the reliability of the precast concrete block for the seismic wall Can be improved.
