Description

[Technical Field]

[0001] The present invention relates to a method for joining concrete blocks. [Background technology]

[0002] Conventionally, a method for joining a plurality of prepared precast concrete blocks together vertically or horizontally has been known (see, for example, Patent Document 1). As shown in Figures 23 and 24, a conventional method for joining two concrete blocks XA and XB is known. The protruding end x11 of a reinforcing bar x1 embedded in one concrete block XA is inserted into a joint x22 embedded in the other concrete block XB. The end x21 of a reinforcing bar x2 embedded in the other concrete block XB is disposed within the joint x22. After the protruding end x11 of the reinforcing bar x1 of one concrete block XA is inserted into the joint x22, the joint x22 is filled with a hardening filler W such as grout, thereby joining the protruding end x11 of the reinforcing bar x1 embedded in the joint x22 and the end x21 of the other reinforcing bar x2, thereby properly joining the two concrete blocks XA and XB.

[0003] However, the conventional method of joining concrete blocks described above can only be applied when connecting one concrete block and the other concrete block in one direction, either vertically or horizontally.

[0004] Here, Figure 25 is a schematic reference diagram for easily understanding an example in which application is difficult. As shown in Figure 25, when an attempt is made to apply the conventional concrete block joining method, the reinforcing bar protrusion y11 of the horizontal block Y1 that has been placed in advance and the reinforcing bar protrusion y21 of the lower block Y2 get in the way of moving the other block Y3 to be joined. Even if the reinforcing bar protrusions of both or either of the horizontal block Y1 and the lower block Y2 that have been placed in advance are replaced with joints, the reinforcing bars embedded inside the blocks cannot be properly connected to each other.

[0005] In other words, the conventional method of inserting a protruding rebar portion from one concrete block into a joint in the other concrete block makes it difficult to properly connect the buried rebar, and makes it impossible to properly connect two or more concrete blocks in both the vertical and horizontal directions.

[0022] Hereinafter, first, second, third, fourth and fifth embodiments of the method for joining concrete blocks according to the present invention will be described in order.

[0023] The concrete block joining method shown in each embodiment is applied to the construction of a structure in which multiple concrete blocks are connected vertically and horizontally. Specific examples of structures to which the concrete block joining method is applied include walls, L-shaped retaining walls, box culverts, and vertical shafts.

[0024] <<First embodiment>> A method for joining concrete blocks according to a first embodiment will be described with reference to FIGS.

[0025] The method for joining concrete blocks according to the first embodiment is to connect a first block A1 and a second block A2 in the up-down direction, that is, the vertical direction.

[0026] Although not shown, the horizontal joining of multiple blocks in this embodiment can be easily achieved by applying a conventional joining method as shown in Figures 23 and 24 (although these figures show vertical joining, this can also be applied to horizontal joining), or a horizontal joining method of multiple blocks as shown in the second, third, and fourth embodiments described below.

[0027] The method for joining concrete blocks in the vertical direction involves connecting a first block A1 made of precast concrete in which a plurality of first reinforcing bars t1 extending in the vertical direction are buried so as not to be visible from the outside without protruding from the upward abutment surface m1, which is the upward end surface, and a second block A2 made of precast concrete in which a plurality of second reinforcing bars t2 extending in the vertical direction are buried so as not to be visible from the outside without protruding from the downward abutment surface m2, which is the downward end surface, and the upward abutment surface m3, which is the upward end surface, to each other in a manner in which the upward abutment surface m1 of the first block A1 and the downward abutment surface m2 of the second block A2 are abutting.

[0028] The first block A1 and the second block A2 are generally shaped like rectangular plates.

[0029] The first block A1 is provided with a first reinforcing bar arrangement hole h1 which is arranged adjacent to the first reinforcing bar t1, extends in the vertical direction so as to be approximately parallel to the first reinforcing bar t1, and has an upper opening k1 which is an opening on the upward abutment surface m1.

[0030] In this embodiment, the first reinforcing bar arrangement hole h1 is exemplified as having a bottomed structure for determining the vertical position of the movable reinforcing bar D, but it may be one that penetrates in the vertical direction (i.e., one that has an opening on the underside as well) as long as it is provided with a movement restriction means that can restrict the downward movement of the movable reinforcing bar D at a predetermined position. In other words, the first block A1 may be one that has substantially the same structure as the second block A2.

[0031] The second block A2 is arranged adjacent to the second reinforcing bar t2 and extends in the vertical direction approximately parallel to the second reinforcing bar t2, and is provided with a second reinforcing bar arrangement hole h2, which is a through hole with an upper opening k3 and a lower opening k2 on the upward abutment surface m3 and the downward abutment surface m2, respectively.

[0032] That is, the second reinforcing bar placement hole h2 is provided to penetrate in the vertical direction so as to form an upper opening k3 on the upward abutment surface m3 and a lower opening k2 on the downward abutment surface m2.

[0033] A movement restricting means J for restricting downward movement of other movable reinforcing bars Dx is provided in the middle of the second reinforcing bar arrangement hole h2 in the longitudinal direction of the second block A2.

[0034] The movement control means J is intended to position another movable reinforcing bar Dx, which is used when connecting the second block A2 to another block (not shown) to be placed on top of it, at a predetermined vertical position in the second reinforcing bar placement hole h2.

[0035] The movement restriction means J in this embodiment is mainly composed of a horizontally drilled insertion hole j1 and a rod-shaped movement restriction member j2 inserted into the insertion hole j1. The second block A2 is provided with a horizontally extending insertion hole j1 that communicates with the longitudinal middle of the second rebar installation hole h2. A rod-shaped movement restriction member j2 is inserted into the insertion hole j1, with which the lower end of another movable rebar Dx descending through the second rebar installation hole h2 can engage. A movement restriction means J configured in this manner can appropriately position another movable rebar Dx at a predetermined vertical position. It goes without saying that any other configuration can be applied to the movement restriction means J as long as it is capable of positioning the other movable rebar Dx in the vertical direction.

[0036] The concrete block joining method according to the first embodiment includes a block disposing step S1, a movable reinforcing bar disposing step S2, and a filler filling step (not shown).

[0037] In the block placement step S1, the second block A2 is placed on the first block A1 by abutting the downward contact surface m2 of the second block A2 against the upward contact surface m1 of the first block A1. The second block A2 is placed on the first block A1 so that the second reinforcing bar placement hole h2 can communicate with the first reinforcing bar placement hole h1 in the vertical direction.

[0038] In the block disposing step S1, when the upward contact surface m1 and the downward contact surface m2 are butted against each other, a joining auxiliary material such as an adhesive may be interposed therebetween.

[0039] The movable reinforcing bar installation step S2 is carried out after the block installation step S1.

[0040] The movable reinforcing bar installation process S2 involves lowering a movable reinforcing bar D, which extends linearly in the vertical direction, through a second reinforcing bar installation hole h2 that penetrates the second block A in the vertical direction, so that the lower longitudinal half of the movable reinforcing bar D is positioned within the first reinforcing bar installation hole h1 in the first block A1 and the upper longitudinal half is positioned within the second reinforcing bar installation hole h2 in the second block A2.

[0041] More specifically, the movable reinforcing bar installation process S2 involves, after the block installation process S1, inserting the movable reinforcing bar D through the upper opening k3 in the second reinforcing bar installation hole h2 and lowering it through the second reinforcing bar installation hole h2, while passing the lower half of the movable reinforcing bar D through the lower opening k2 and the upper opening k1 in the first block A to insert it into the first reinforcing bar installation hole h1.

[0042] The filler filling step is carried out after the movable reinforcing bar arrangement step S2.

[0043] The filler filling process involves filling the first reinforcing bar arrangement hole h1 and the second reinforcing bar arrangement hole h2, inside which the movable reinforcing bar D is arranged, with a hardening filler material such as mortar (not shown) through filling holes (not shown) provided in the first block A1 and the second block A2.

[0044] <<Second embodiment>> Next, a method for joining concrete blocks according to a second embodiment will be described with reference to FIGS.

[0045] The method of joining concrete blocks according to the second embodiment is to join a first block B1 and a second block B2 in the left-right or horizontal direction.

[0046] Although not shown, the vertical joining of multiple blocks in this embodiment can be easily carried out by applying a conventional joining method as shown in Figures 23 and 24, or a method for joining multiple blocks as shown in the first embodiment described above or the fifth embodiment described below.

[0047] The horizontal joining method for concrete blocks involves connecting a first block B1 made of precast concrete in which a plurality of first reinforcing bars u1 extending in the left-right direction are buried so as not to be visible from the outside without protruding from the first horizontal abutment surface n1, which is the end face, and a second block B2 made of precast concrete in which a plurality of second reinforcing bars u2 extending in the left-right direction are buried so as not to be visible from the outside without protruding from the second horizontal abutment surface n2, which is the end face, in such a way that the first horizontal abutment surface n1 of the first block B1 abuts against the second horizontal abutment surface n2 of the second block B2.

[0048] The first block B1 and the second block B2 are generally rectangular plate-shaped.

[0049] The first block B1 is formed with a first space sp1 that is open only upward and on one side and has a first lateral contact surface n1.

[0050] The second block B2 is formed with a second space sp2 that is open only to the top and one side and has a second lateral contact surface n1.

[0051] The concrete block joining method according to the second embodiment includes a block disposing step P1, a unit reinforcing bar body disposing step P2, and a filler filling step P3.

[0052] In the block disposing step P1, the second block B2 is disposed next to the first block B1 so that the second horizontal abutment surface n2 of the second block B2 abuts against the first horizontal abutment surface n1 of the first block B1. In the block disposing step P1, when the first horizontal abutment surface n1 and the second horizontal abutment surface n2 are abutted against each other, a joining auxiliary material such as an adhesive may be used.

[0053] The unit reinforcing bar body installation process P2 involves arranging the unit reinforcing bar body E, which will be described in detail later, in the unit reinforcing bar body installation space SP formed by the first space portion sp1 and the second space portion sp2, and is performed after the block installation process P1.

[0054] The unit reinforcing bar installation process P2 involves lowering the unit reinforcing bar E into the unit reinforcing bar installation space SP formed by the first space portion sp1 and the second space portion sp2, so that one horizontal half portion ea of ​​the unit reinforcing bar E is positioned within the first space portion sp1 and the other horizontal half portion eb is positioned within the second space portion sp2.

[0055] After the unit reinforcing bar body installation process P2, when the unit reinforcing bar body E is installed in the unit reinforcing bar body installation space SP, at least a portion of the horizontal reinforcing bars e1 that make up the unit reinforcing bar body E is installed adjacent to the first reinforcing bar u1 embedded in the first block B1 and the second reinforcing bar u2 embedded in the second block B2 at approximately the same height.

[0056] Here, the unit reinforcing bar body E is a structure configured by connecting a plurality of reinforcing bars, namely horizontal reinforcing bars e1 and connecting reinforcing bars e2, so that the entire structure can be handled as a single unit. The unit reinforcing bar body E is configured including a plurality of horizontal reinforcing bars e1 extending horizontally and arranged at regular intervals in the vertical direction, and a plurality of connecting reinforcing bars e2 extending vertically and connecting the plurality of horizontal reinforcing bars e1.

[0057] The filler filling step P3 is carried out after the unit reinforcing bar body installation step P2.

[0058] The filler filling step P3 is a step of filling a hardening filler W such as mortar into the unit reinforcing bar body arrangement space SP in which the unit reinforcing bar bodies E are arranged.

[0059] <<Third embodiment>> A method for joining concrete blocks according to the third embodiment will be described with reference to FIGS.

[0060] The method of joining concrete blocks according to the third embodiment is to join a first block C1 and a second block C2 in the left-right direction, that is, horizontally.

[0061] Although not shown, the joining of multiple blocks together in the vertical direction in this embodiment can be easily carried out by applying a conventional joining method as shown in Figures 23 and 24, or a joining method of multiple blocks together as shown in the first embodiment described above or the fifth embodiment described below.

[0062] The horizontal joining method for concrete blocks involves connecting a first block C1 made of precast concrete in which a plurality of first reinforcing bars v1 extending in the left-right direction are arranged without protruding outward from their outermost end faces, the first horizontal abutment surface q1, and a second block C2 made of precast concrete in which a plurality of second reinforcing bars v2 extending in the left-right direction are arranged without protruding outward from their outermost end faces, the second horizontal abutment surface q2, so that the first horizontal abutment surface q1 of the first block C1 abuts against the second horizontal abutment surface q2 of the second block C2.

[0063] The first block C1 and the second block C2 are generally shaped like rectangular plates.

[0064] The first block C1 has a first notch g1 formed near the first horizontal abutment surface q1, and a cantilevered first reinforcing bar protrusion v11 formed by one end of the first reinforcing bar v1 is disposed in the first notch g1. The position of the protruding end of the first reinforcing bar protrusion v11 is set so as not to be located outside the first horizontal abutment surface q1.

[0065] The second block C2 has a second cutout g2 formed near the second horizontal abutment surface q2, and a cantilevered second reinforcing bar protrusion v21 formed by one end of the second reinforcing bar v2 is disposed in the second cutout g2. The position of the protruding end of the second reinforcing bar protrusion v21 is set so as not to protrude outward beyond the second horizontal abutment surface q2.

[0066] The concrete block joining method according to the third embodiment includes a block disposing step R1, a joint disposing step R2, and a filler filling step R3.

[0067] In the block disposing step R1, the second block C2 is disposed next to the first block C1 so that the second horizontal abutment surface q2 of the second block C2 abuts against the first horizontal abutment surface q1 of the first block C1. In the block disposing step R1, when the first horizontal abutment surface q1 and the second horizontal abutment surface q2 are abutted against each other, a bonding aid such as an adhesive may be used.

[0068] The joint arrangement step R2 is carried out after the block arrangement step R1.

[0069] The joint installation process R2 is to connect the tip end portion of the first reinforcing bar protrusion v11 and the tip end portion of the second reinforcing bar protrusion v21 with a joint F, which is a movable joint that is not embedded in the block.

[0070] In this embodiment, the joint installation process R2 is carried out by horizontally moving the cylindrical joint F, which has been temporarily attached to the second reinforcing bar protrusion v21 in advance in the block installation process R1, to a position where it can surround both the tip portion of the first reinforcing bar protrusion v11 and the tip portion of the second reinforcing bar protrusion v21.

[0071] The filler filling step R3 is carried out after the joint installation step R2.

[0072] The filler filling step R3 is a step of filling the first notch g1 and the second notch g2 with a hardening filler W such as mortar or concrete.

[0073] <<Fourth embodiment>> A method for joining concrete blocks according to the fourth embodiment will be described with reference to FIGS.

[0074] The method of joining concrete blocks according to the fourth embodiment is to connect a first block L1 and a second block L2 in the horizontal direction (left-right direction) and in the front-rear direction.

[0075] In this embodiment, the second block L2 and the third block L3 are joined together (joined in the front-rear direction) using a conventional joining method as shown in FIGS.

[0076] The method for joining concrete blocks horizontally (left-right) involves connecting a first block L1 made of precast concrete, in which multiple first reinforcing bars tk1 extending left-right are arranged without protruding outward from the first horizontal abutment surface i1, which is the outermost end surface, to a second block L2 made of precast concrete, in such a manner that the first horizontal abutment surface i1 of the first block L1 abuts against the second horizontal abutment surface i2 of the second block L2.

[0077] The first block L1 has a generally rectangular plate shape. The second block L2 has a generally rectangular column shape extending in the vertical direction. Cast-in-place concrete is poured between the pair of first blocks L1, which are rectangular plate-shaped and arranged generally parallel to each other, and between the pair of third blocks L3, which are rectangular plate-shaped and arranged generally parallel to each other.

[0078] The first block L1 has a plurality of horizontally extending, generally cylindrical joints tg embedded in it so that they are open to the first horizontal abutment surface i1. The end tn of the first reinforcing bar tk1 is disposed within the joints tg embedded in the first block L1. The first horizontal abutment surface i1 of the first block L1 is a smooth, upright surface.

[0079] The second block L2 has a reinforcing bar installation hole th penetrating horizontally at a location corresponding to the joint tg of the first block L1. A second reinforcing bar tk2 having at least a portion extending in the front-rear direction is embedded in the second block L2, and its extending end constitutes a reinforcing bar protruding portion tke that protrudes rearward beyond a rearward end face i3, which is perpendicular to the second horizontal abutment face i2.

[0080] The method for joining concrete blocks according to the fourth embodiment includes a block disposing step Z1, a movable reinforcing bar disposing step Z2, and a filler filling step Z3.

[0081] In the block disposing step Z1, the second block L2 is disposed next to the first block L1 so that the second horizontal abutment surface i2 of the second block L2 abuts against the first horizontal abutment surface i1 of the first block L1. In the block disposing step Z1, when the first horizontal abutment surface tm1 and the second horizontal abutment surface tm2 are abutted against each other, a joining auxiliary material such as an adhesive may be used.

[0082] In this embodiment, the block installation process Z1 includes a process of inserting a reinforcing bar protrusion tke protruding from the second block L2 into a joint tg embedded in a pair of third blocks L3 arranged in a direction approximately perpendicular to the first block L1.

[0083] The movable reinforcing bar installation process Z2 is carried out after the block installation process Z1.

[0084] The movable reinforcing bar installation process Z2 involves inserting a movable reinforcing bar TX extending horizontally (left and right) into the reinforcing bar installation hole th from the outside, positioning the insertion end TXe of the movable reinforcing bar TX within the joint tg embedded in the first block L1, and positioning the portion other than the insertion end TXe over almost the entire longitudinal area of ​​the reinforcing bar installation hole th.

[0085] The filler filling step Z3 is carried out after the movable reinforcing bar arrangement step Z2.

[0086] The filler filling step Z3 is a step of filling the joint tg and the reinforcing bar arrangement hole th with a hardening filler W.

[0087] In this embodiment, cast-in-place concrete is poured between the opposing faces of a pair of first blocks L1 butted against the second blocks L2, or between the opposing faces of a pair of third blocks L3, but this is not limited to this. Instead of the pair of first blocks L1 or the pair of third blocks L3, for example, a single precast concrete block butted against the second blocks L2 and incorporating reinforcing bars and joints therein may be used.

[0088] <<Fifth Embodiment>> A method for joining concrete blocks according to a fifth embodiment will be described with reference to Figures 20 to 22. Since the fifth embodiment has a configuration similar to that of the first embodiment, the same or corresponding components will be denoted by the same reference numerals.

[0089] The method of joining concrete blocks according to the fifth embodiment is to connect a first block A1 and a second block A2 in the up-down direction, that is, the vertical direction.

[0090] Although not shown, the horizontal joining of multiple blocks in this embodiment can be easily carried out by applying a conventional joining method as shown in Figures 23 and 24 (although the figures show vertical joining, this can also be applied to horizontal joining), or a horizontal joining method of multiple blocks as shown in the second, third, and fourth embodiments.

[0091] The method for joining concrete blocks in the vertical direction involves connecting a first block A1 made of precast concrete in which a plurality of first reinforcing bars t1 extending in the vertical direction are buried so as not to be visible from the outside without protruding from the upward abutment surface m1, which is the upward end surface, and a second block A2 made of precast concrete in which a plurality of second reinforcing bars t2 extending in the vertical direction are buried so as not to be visible from the outside without protruding from the downward abutment surface m2, which is the downward end surface, and the upward abutment surface m3, which is the upward end surface, to each other in a manner in which the upward abutment surface m1 of the first block A1 and the downward abutment surface m2 of the second block A2 are abutting.

[0092] The first block A1 and the second block A2 are generally shaped like rectangular plates.

[0093] The first block A1 is provided with a bottomed first reinforcing bar arrangement hole h1x which is arranged adjacent to the first reinforcing bar t1, extends in the vertical direction so as to be approximately parallel to the first reinforcing bar t1, and has an upper opening k1 which is an opening on the upward abutment surface m1.

[0094] The second block A2 is arranged adjacent to the second reinforcing bar t2, extends in the vertical direction so as to be approximately parallel to the second reinforcing bar t2, and has a bottomed second reinforcing bar arrangement hole h2x with a lower opening k2 that is an opening on the downward abutment surface m2.

[0095] Furthermore, the second block A2 is provided with a bottomed third reinforcing bar arrangement hole h3x which is arranged adjacent to the second reinforcing bar t2, extends in the vertical direction so as to be approximately parallel to the second reinforcing bar t2, and has an upper opening k3 which is an opening on the upward abutment surface m3.

[0096] That is, the second reinforcing bar arrangement hole h2x and the third reinforcing bar arrangement hole h3x are each provided separately and have a bottom.

[0097] The method for joining concrete blocks according to the fifth embodiment includes a movable reinforcing bar arrangement step ST1, a block arrangement step ST2, and a filler filling step (not shown).

[0098] The movable reinforcing bar installation process ST1 involves inserting a movable reinforcing bar Dz extending in the vertical direction into each of the multiple bottomed first reinforcing bar installation holes h1x drilled in a first block A1 installed at a predetermined location such as a foundation, and positioning the lower longitudinal half of the movable reinforcing bar Dz within the first reinforcing bar installation hole h1x.

[0099] The block installing step ST2 is carried out after the movable reinforcing bar installing step ST1.

[0100] The block placement process ST2 involves inserting the longitudinal upper half of the movable reinforcing bar Dz protruding upward from the upward abutment surface m1 of the first block A1 into the bottomed second reinforcing bar placement hole h2x, while butting the downward abutment surface m2 against the upward abutment surface m1 to place the second block A2 on top of the first block A1.

[0101] In the block disposing step ST2, when the upward contact surface m1 and the downward contact surface m2 are butted against each other, a joining auxiliary material such as an adhesive may be interposed therebetween.

[0102] The filler filling step is carried out after the block disposing step ST2.

[0103] The filler filling process involves filling the first reinforcing bar arrangement hole h1x and the second reinforcing bar arrangement hole h2x, inside which the movable reinforcing bar Dx is arranged, with a hardening filler material such as mortar (not shown) through filling holes (not shown) provided in the first block A1 and the second block A2.

[0104] In this embodiment, the first reinforcing bar arrangement hole h1x and the second reinforcing bar arrangement hole h2x each have a bottom, and their depth dimensions are set to correspond to the movable reinforcing bar Dx, which is set to a length that can ensure a predetermined lap joint length for the first reinforcing bar t1 and the second reinforcing bar t2. Therefore, the amount of hardenable filler filled into the first reinforcing bar arrangement hole h1x and the second reinforcing bar arrangement hole h2x can be appropriate and waste can be reduced.

[0105] As explained above, the concrete block joining methods exemplified as the first, second, third, fourth and fifth embodiments can provide the following effects.

[0106] <Operational Effects of the First Embodiment> The method of joining concrete blocks shown in the first embodiment makes it possible to suitably join at least a first block A1 made of precast concrete and a second block A2 made of precast concrete.

[0107] In other words, the block placement process S1 involves abutting the smooth upward abutment surface m1 of the first block A1 against the smooth downward abutment surface m2 of the second block A2, so that the second block A2 can be suitably placed on the first block A1 while making flexible fine adjustments to its position in the horizontal direction without being hindered by protruding objects such as reinforcing bars as in conventional examples.

[0108] Moreover, by going through the movable reinforcing bar arrangement step S2 and the filler filling step S3, a strong connection between the first block A1 and the second block A2 in the vertical direction can be suitably achieved.

[0109] Furthermore, by combining the method of joining concrete blocks in the vertical direction shown in the first embodiment with the method of joining concrete blocks in the horizontal direction shown in the second, third, and fourth embodiments or known methods of joining concrete blocks in the horizontal direction, it is possible to easily connect two or more concrete blocks in both the vertical and horizontal directions.

[0110] Since the first block A1 and the second block A2 are rectangular plate-shaped overall, joining in the vertical direction, i.e., joining between the upward abutment surface m1 and the downward abutment surface m2, is performed smoothly, and horizontal joining to other blocks (not shown) located adjacent to the first block A1 or the second block A2 is also performed smoothly.

[0111] The second reinforcing bar arrangement hole h2 is provided so as to penetrate in the vertical direction. Then, in the movable reinforcing bar arrangement step S2, after the block arrangement step S1, the movable reinforcing bar D is inserted from the upper opening k3 of the second reinforcing bar arrangement hole h2 and lowered into the second reinforcing bar arrangement hole h2.

[0112] Therefore, the movable reinforcing bar D can be inserted through the upper opening k3 formed in the second block A2 and suitably arranged at a predetermined position through the second reinforcing bar arrangement hole h2. Furthermore, since the upper opening k3 is provided in the second block A2, when another block to be connected to the second block A2 is arranged on top of the second block A2, the other movable reinforcing bar Dx can be suitably arranged at a predetermined position.

[0113] A movement restriction means J for restricting downward movement of the other movable reinforcing bars Dx is provided at the longitudinal middle of the second reinforcing bar placement hole h2. Therefore, when another block (having substantially the same shape as the second block A2) to be connected to the second block A2 is placed on top of the second block A2, the other movable reinforcing bars Dx can be suitably positioned.

[0114] <Operational Effects of the Second Embodiment> The method of joining concrete blocks shown in the second embodiment makes it possible to suitably join at least a first block B1 made of precast concrete and a second block B2 made of precast concrete.

[0115] In other words, the block placement process P1 involves abutting the first horizontal abutment surface n1, which is a smooth upright surface on the first block B1, against the second horizontal abutment surface n2, which is a smooth upright surface on the second block B2, so that the second block B2 can be suitably placed next to the first block B1 while making flexible fine adjustments to its position in the vertical and horizontal directions without being hindered by protruding objects such as reinforcing bars.

[0116] Furthermore, by going through the unit reinforcing bar body installation step P2 and the filler filling step P3, a strong connection in the horizontal direction between the first block B1 and the second block B2 can be suitably achieved.

[0117] Furthermore, by combining the method of joining concrete blocks in the left-right direction shown in the second embodiment with the method of joining concrete blocks in the up-down direction shown in the first embodiment or a known method of joining concrete blocks in the up-down direction, it is possible to easily connect two or more concrete blocks in both the up-down direction and the left-right direction.

[0118] Since the first block B1 and the second block B2 are rectangular plate-shaped overall, joining in the left-right direction, i.e., joining between the first horizontal abutment surface n1 and the second horizontal abutment surface n2, is performed smoothly, and joining in the up-down direction to other blocks adjacent to the first block B1 or the second block B2 above or below is also performed smoothly.

[0119] At least a portion of the horizontal reinforcing bar e1 in the unit reinforcing bar body E is disposed adjacent to the first reinforcing bar u1 and the second reinforcing bar u2 at approximately the same height when disposed in the unit reinforcing bar body installation space SP.

[0120] Therefore, the overlap joint length of the horizontal reinforcing bar e1 in the unit reinforcing bar body E relative to the first reinforcing bar u1 in the first block B1, and the overlap joint length of the horizontal reinforcing bar e1 in the unit reinforcing bar body E relative to the second reinforcing bar u2 in the second block B2 are each appropriately secured.

[0121] <Operational Effects of the Third Embodiment> The method of joining concrete blocks shown in the third embodiment makes it possible to suitably join at least a first block C1 made of precast concrete and a second block C2 made of precast concrete.

[0122] In other words, the block placement process R1 involves abutting the first horizontal abutment surface q1, which is a smooth upright surface on the first block C1, against the second horizontal abutment surface q2, which is a smooth upright surface on the second block C2, so that the second block C2 can be suitably placed next to the first block C1 while making flexible fine adjustments to its position in the vertical and horizontal directions without being hindered by protruding objects such as reinforcing bars.

[0123] Furthermore, by going through the joint installation step R2 and the filler filling step R3, a strong connection in the horizontal direction between the first block C1 and the second block C2 can be suitably achieved.

[0124] Furthermore, by combining the method of joining concrete blocks in the left-right direction shown in the third embodiment with the method of joining concrete blocks in the up-down direction shown in the first embodiment or a known method of joining concrete blocks in the up-down direction, it is possible to easily connect two or more concrete blocks in both the up-down direction and the left-right direction.

[0125] Since the first block C1 and the second block C2 are rectangular plate-shaped as a whole, joining in the left-right direction, i.e., joining between the first horizontal abutment surface q1 and the second horizontal abutment surface q2, is performed efficiently, and joining in the up-down direction to other blocks adjacent to the first block C1 or the second block C2 above or below is also performed efficiently.

[0126] The joint installation process R2 is carried out by moving the cylindrical joint F, which has been temporarily attached to either the first reinforcing bar protrusion v11 or the second reinforcing bar protrusion v21 in advance in the block installation process R1, to a position where it can surround both the tip portion of the first reinforcing bar protrusion v11 and the tip portion of the second reinforcing bar protrusion v21.

[0127] Therefore, the cylindrical joint F can be disposed at an appropriate location simply by moving it horizontally.

[0128] <Operational Effects of the Fourth Embodiment> The method of joining concrete blocks shown in the fourth embodiment makes it possible to suitably join at least a first block T1 made of precast concrete and a second block T2 made of precast concrete.

[0129] In other words, the block placement process Z1 involves abutting the first horizontal abutment surface i1, which is a smooth upright surface on the first block L1, against the second horizontal abutment surface i2, which is a smooth upright surface on the second block L2, so that the second block L2 can be suitably placed next to the first block L1 while making flexible fine adjustments to its position in the vertical and horizontal directions without being hindered by protruding objects such as reinforcing bars.

[0130] Moreover, by going through the movable reinforcing bar arrangement step Z2 and the filler filling step Z3, a strong connection in the horizontal direction between the first block L1 and the second block L2 can be suitably achieved.

[0131] <Regarding the effects of the fifth embodiment> The method of joining concrete blocks shown in the fifth embodiment makes it possible to suitably join at least a first block A1 made of precast concrete and a second block A2 made of precast concrete.

[0132] In addition, the first reinforcing bar arrangement hole h1x provided in the first block A1 and the second reinforcing bar arrangement hole h2x provided in the second block A2 each have a bottom, and their depth dimensions are set to correspond to the movable reinforcing bar Dx, which is set to a length that can ensure a specified lap joint length for the first reinforcing bar t1 and the second reinforcing bar t2.

[0133] Therefore, with the configuration of the fifth embodiment, the amount of hardening filler filled into the first reinforcing bar arrangement hole h1x and the second reinforcing bar arrangement hole h2x can be made appropriate with reduced waste.

[0134] The present invention is not limited to the above-described embodiment.

[0135] The first block and the second block are not limited to being generally rectangular plates as a whole, but may be, for example, blocks having curved end faces so that the edges appear arcuate when viewed from a specific direction, or blocks having irregularities.

[0136] The first block and the second block do not have to be configured to be approximately the same size. However, if the first block and the second block are approximately the same size and structure, they can be managed without having to worry about the differences between the first block and the second block, which is convenient for parts management and management during installation.

[0137] Needless to say, the first block and the second block may have various types of reinforcing bars embedded therein.

[0138] The first reinforcing bar placement hole provided in the first block may have an opening at least on the upward contact surface.

[0139] The second reinforcing bar placement hole provided in the second block may have an opening at least on the downward contact surface.

[0140] The unit reinforcing bar body may be any structure that includes multiple horizontal reinforcing bars extending horizontally and arranged at regular intervals in the vertical direction, and one or more connecting reinforcing bars extending vertically and connecting the multiple horizontal reinforcing bars, and a more specific structure can be set as appropriate.

[0141] The joint used in the joint installation process may be, for example, a half-split structure that can be easily attached later.

[0142] The joining of the first block and the second block in the vertical or horizontal direction may be performed by combining a joining method that forms a lap joint with the joining method that uses a so-called mechanical joint.

[0143] That is, the first block has an extending portion that extends outward from the upward or horizontal abutment surface of the embedded first reinforcing bar. The second block has a bottomed reinforcing bar arrangement hole that is disposed adjacent to the embedded second reinforcing bar and extends vertically substantially parallel to the second reinforcing bar, with an opening provided in the downward abutment surface. The extending portion of the first block may be inserted into the reinforcing bar arrangement hole of the second block, while the downward or horizontal abutment surface of the second block is butted against the upward or horizontal abutment surface of the first block, and then the reinforcing bar arrangement hole may be filled with a hardening filler to join the second block to the first block.

[0144] Furthermore, the specific configuration of each part is not limited to the above embodiment, and various modifications are possible within the scope of the present invention. [Explanation of symbols]
