BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction in which various types of concrete blocks produced in a factory can be connected to each other via reinforcing bars at a construction site.

0002

2. Description of the Related Art Conventionally, as a method for firmly connecting a plurality of factory-produced blocks to each other at their side ends, for example, a flange portion for binding is formed in advance on a retaining wall block.
A bolt insertion hole was provided there. Alternatively, in the case of a box culvert buried underground, bolt insertion holes are provided in the wall surface of the box culvert in parallel to the wall surface thereof. Then, both adjacent block bodies were tied together via bolts.

0003

[Problem to be solved] In this conventional method of connecting blocks, the blocks are simply tied together by the head of the bolt, and both blocks are not completely fixed together. The disadvantage was that the bond was weak. Additionally, even if plated bolts are used, the bolts are susceptible to corrosion and are unreliable. In particular, there was a risk that reliability would be lacking when large blocks were joined together. In addition, a method of protruding reinforcing bars from the side ends of the blocks in advance and connecting adjacent blocks via the reinforcing bars can also be considered, but in that case, alignment of the adjacent blocks with each other becomes a problem, As a result, there was a risk that construction would become troublesome. Therefore, the present invention aims to solve all of the above problems.

0004

[Means for Solving the Problems] The present invention provides a block body 1
In a concrete block to which the end of another block body 1 is connected, a groove 2 is formed in the longitudinal direction at the end, and a pair of protrusions 3, 4 are formed on both sides of the groove 2. , the height of one protrusion 3 is made higher than that of the other. A plurality of reinforcing bars 5 are embedded in the block body 1 so as to be electrically conductive to each other, and their ends protrude into the grooves 2, respectively. In addition to the above configuration, the invention of claim 2 has the following features:
A metal body 6 is buried at the end of a protrusion 3 having a high protrusion height so that its surface is exposed. At the same time, the metal body 6 and the reinforcing bar 5 are electrically connected to each other. Next, claim 3
In the invention described in 1., a protruding strip 3 is formed on one edge of the side end of the block body 1, and a plurality of reinforcing bars 5 are buried in the block body 1 while being electrically connected to each other, and the end portions of the reinforcing bars 5 are buried. They respectively protrude into the recesses at the side ends of the block body 1. Further, a metal body 6 is buried at the end of the protrusion 3 so that its surface is exposed, and the metal body 6 and the reinforcing bar 5 are connected so as to be electrically conductive.

Next, the invention of a method for constructing a concrete block according to claim 4 uses the block body according to claim 2, and brings the metal bodies 6, 6 exposed at the ends of adjacent concrete blocks into contact with each other. Alternatively, the reinforcing bars 5, 5 may be placed very close to each other, fixed by welding, and the reinforcing bars 5, 5 may be connected to each other, and then mortar or fresh concrete is filled between both ends thereof and hardened. Next, the construction method according to claim 5 is the method according to claim 4, in which the gap on the protruding strip 3 side is closed with a closing body 7, and the closing body 7 and the reinforcing bar 5 are tied together with wire rods, hook bolts, etc. The block body 7 is fixed to the surface of the block body. Furthermore, in the concrete block according to claim 6, in the block according to claim 1, a concave portion 8 for fitting an elastic packing is provided along the longitudinal direction of the concave groove side edge of the convex strip 3 having a higher protrusion height. At the same time, a waterproof layer 9 is provided on the outer periphery of the block body including the concave portion 8. Further, the concrete block according to claim 7 is the concrete block according to claim 6, which has a recess 8 for fitting the elastic packing.
is formed in the second groove where the side wall on the side of the groove 2 is lowered.

[0006]

[Operation] As shown in FIG. 4, the ends of adjacent block bodies 1, 1 are brought into contact with each other, and the metal bodies 6 are brought into contact with each other. Thereby, the ends of the block bodies 1, 1 can be easily aligned. Therefore, the metal bodies 6 that are in contact with each other are welded by electric welding. At the same time, the reinforcing bars 5 protruding into the groove 2 are welded or tied together with a binding wire. Furthermore, the closing body 7 is placed on the open side of the joint between the two blocks, and the closing body 7 and the reinforcing bars 5 are bound together and fixed by a binding wire 13. Therefore, the space formed between the closure body 7 and the block body 1 is filled with fresh concrete 16, and it is allowed to harden. Then, the closing body 7 is removed and the binding wire 13 is cut, thereby completing the joining of the concrete blocks.

[0007]

Embodiments Next, each embodiment of the present invention will be explained based on the drawings. 1 to 4 show a first embodiment of the present invention,
This is an example of application to an L-shaped block for earth retaining. In this block, the vertical outer surface of the block body 1 constitutes a wall surface,
All or part of the L-shaped inner surface is buried in the soil. The block main body 1 is continuous in both side directions. The overall shape of this block body 1 is conventionally known. The feature of the present invention lies in the structure of both ends of the block body. That is, L is provided at both ends of the block body 1.
A concave groove 2 is formed on the center line of the L-shape along the L-shape. The cross-sectional shape of this groove 2 is formed into a trapezoidal shape slightly widening toward the end or a cutout shape of a concrete formwork. By this groove 2, a pair of protrusions 3 are formed on both sides of the groove 2.
4 is formed. Moreover, the protruding height of the protruding stripes 3 located on the outer circumferential side is higher than that of the protruding stripes 4 on the inner side. Further, a metal body 6 made of an angle material is embedded in the edge of the protruding strip 3 on the groove 2 side, and its outer surface is exposed. The exposed outer surface has two orthogonal surfaces, one of which is formed substantially the same as the tip end surface of the protrusion 3, and the other surface exists on an extension of the wall surface of the groove 2. Next, inside the block body 1, a large number of horizontal reinforcing bars 5 and vertical vertical bars 10 are arranged in a grid pattern, and the intersections between the two are electrically connected by binding wires 13 or welding. Ru. And vertical stripes 10
is formed in an L-shape along the longitudinal section of the block body 1. Further, the metal body 6 buried in the edge of the protruding strip 3, the reinforcing bars 5, and the vertical bars 10 are electrically connected to each other so as to be electrically conductive. That is, as shown in FIGS. 2 and 3, the metal body 6 and the reinforcing bar 12 are electrically connected through the spot weld 11, and the reinforcing bar 12 and the horizontal reinforcing bar 5 are electrically connected through the binding wire 13 or electric welding. has been done. This horizontal reinforcing bar 5 is projected into the groove 2 on both sides of the block body 1. This protrusion length is preferably shorter than twice the protrusion height of the protrusion 3. In this way, the reinforcing bars and the metal body 6 are all electrically connected to each other so as to be electrically conductive.

Next, a retaining wall can be formed using such concrete blocks in the following manner. First of all,
The construction site is excavated, the bottom is made flat, and chestnut stones are laid down and tamped down. Then, underlay concrete is poured, and after it hardens, the overhanging portion 18 of the concrete block is placed on the underlay concrete. A large number of such concrete blocks are arranged, and a wedge or the like is interposed between the lower surface of the concrete block and the underlaying concrete to align the levels of each block. Along with that,
The outer wall surfaces are aligned and the respective protrusions 3 are butted against each other as shown in FIG. Then, the respective metal bodies 6 come into contact with each other or come very close to each other. Therefore, the pair of metal bodies 6 are joined by electric welding. The welded parts 14 formed at this time are arranged along the longitudinal direction of the ready-mixed concrete 16 in a spot-welded manner at appropriate intervals. In addition, when electrically welding the metal bodies 6 together, it is sufficient to engage the earth side clamp of the electric welding machine on the protrusion of a suitable reinforcing bar 5. Because reinforcing bar 5
This is because the metal body 6 and the metal body 6 are energized. Further, this welding may be performed from the gap between the reinforcing bars 5 arranged vertically. Next, the ends of the reinforcing bars 5 of adjacent block bodies 1 are bound together by electric welding or binding wire. The reinforcing bars 5 and 12 are made of deformed reinforcing bars as shown in Fig. 3, and are in close contact with the concrete within the block body 1, and the presence of the uneven surface formed on the outer periphery of the protruding portion at the protruding end prevents the binding line from forming. It is easy to tie.

Note that if the protruding length of the reinforcing bars 5 is short and it is not possible to directly bind or weld them together with a bind wire, connect both ends of the reinforcing bars to each block body 1 via short reinforcing bars.
It may be welded to the reinforcing bars 5. In addition, block body 1
The reinforcing bars 5 protruding from both ends of the reinforcing bars 5 may be stepped in advance so that adjacent reinforcing bars 5 do not interfere with each other. That is, in FIG. 2, the reinforcing bars 5 protruding from both sides of the block body 1
By slightly shifting the height or width direction of one of the blocks, it is possible to prevent the reinforcing bars 5 from interfering with each other when the ends of adjacent blocks are butted against each other. When the metal bodies 6 and the reinforcing bars 5 of the block bodies 1 are connected in this manner, the opening sides of both block bodies 1 are closed by the temporary frame closing body 7. A board material such as plywood can be used as the closing body 7, and by drilling a through hole for the binding wire 13 at an appropriate position, winding it in a ring between the reinforcing bar 5 and the closing body 7, and binding it. The closure body 7 can be fixed. Further, if a hook bolt is used instead of the binding wire 13, the work will be faster. Next, the elongated space surrounded by the closing body 7, the groove 2, and the protruding strip 4 is filled with fresh concrete 16 as mortar or joint concrete. This fresh concrete 16 is filled in an L-shape on both sides of the block body 1 in FIG. At this time, the adjacent block bodies 1, 1 are reliably positioned and fixed by the welded portions 14 of the metal bodies 6, 6, and an accurate and attractive retaining wall surface can be formed. Next, after waiting for the fresh concrete 16 to harden, the retaining wall is completed by backfilling the overhanging portion 18 in FIG. 1 with soil.

Next, FIG. 5 is a schematic diagram of a construction method when the wall surface of the retaining wall is partially curved in the protruding direction. That is, this is a case where the vertical wall surfaces of adjacent block bodies 1, 1 differ by an angle A at their connecting portions. In this case, the intersecting angle is A,
The edges of the metal bodies 6 of both blocks are brought into contact with each other, and the contact portions are electrically welded. Then, the protruding ends of the reinforcing bars 5 are slightly bent, and adjacent reinforcing bars 5 are electrically welded or bound and fixed to a binding wire. Other construction steps are carried out in the same manner as in FIG. Further, FIG. 5a is a schematic diagram of a construction method when the wall surface of the retaining wall is partially curved in the opposite direction to the case of FIG. 5. That is, this is a case where the vertical wall surfaces of adjacent block bodies 1, 1 differ by an angle A so that the vertical wall surfaces are concave at their connecting portions. In this embodiment, the metal bodies 6 of the pair of gutter block bodies 1 cannot be brought into contact with each other. Therefore, the closing bodies 7 are placed on the front and back sides of each block body, respectively, and are bound and fixed to the reinforcing bars 5 via the hook bolts 20 and the nants 19. Then, the gap between both block bodies is filled with fresh concrete. In this case as well, the reinforcing bars 5, 5 of both block bodies 1 are joined to each other by electric welding or tied together with a binding wire. Note that if the amount of protrusion of the reinforcing bars 5 of the block body 1 is relatively short and adjacent reinforcing bars cannot be connected to each other, they can be integrated via a new connecting reinforcing bar.

Next, FIG. 6 shows a concrete block and its construction method according to another embodiment of the present invention. This concrete block is for constructing waterproof structures such as basements. This block body 1 is different from those shown in FIGS. 1 to 4 in that a stepped recess 8 is formed at the edge of the protrusion 3 on the groove 2 side, and that the outer periphery of the block body 1 including this recess 8 is This is the point where the waterproof layer 9 is covered. A known material can be used as this waterproof layer 9, and the waterproof layer 9 can be formed by coating or spraying a waterproofing agent on the outer surface thereof, or by pasting or the like. Furthermore, the material for the waterproof layer 9 may be synthetic rubber, FRP, or the like. Further, in this embodiment, the reinforcing bar 5 protruding from the end of the block body 1 is threaded with a male thread. In addition, this reinforcing bar 5 to be threaded
Only some reinforcing bars spaced apart from each other may be used, and the rest may be welded. Therefore, Fig. 6 shows the distance between the adjacent block bodies 1 and 1.
An elastic packing 15 is interposed between the two abutting concave portions 8 as shown in FIG. This elastic packing 15 may be made of a synthetic rubber material having a circular cross section. And the adjacent reinforcing bars 5, 5
The space between them is tied together with a nut 19. That is, both ends of the nut 19 are screwed onto the ends of a pair of opposing reinforcing bars 5, respectively, and the nut 1
By screwing the block 9 in one direction, the adjacent block bodies 1, 1 are brought close to each other. Then, the elastic packing 15
is compressed, forming a liquid-tight boundary. Therefore, the open side of the boundary is closed with a closing body 7, the inside is filled with fresh concrete 16, and the waterproof structure is completed by hardening.

FIG. 6a is a plan view of a basement constructed with such a waterproof structure. Corner blocks 21 are arranged at the four corners of this basement. This corner block is integrally formed with two wall surfaces and a bottom surface formed at right angles, and each vertical section is formed in an L-shape. The grooves and protrusions shown in FIG. 6 are formed at both ends of the wall surface and at the end of the bottom surface. Also, corner block 2
An intermediate block 22 having an L-shaped cross section is arranged between the intermediate blocks 1 and 21. Furthermore, a flat block 23 is placed in the center of the bottom of the basement.
is placed. Then, the respective connecting portions are joined as shown in FIG. Note that if the ceiling height of the basement is relatively high and the height cannot be secured with only one level of concrete blocks, multiple levels of concrete blocks can be arranged in the vertical direction. In that case, a joint shown in FIG. 6 is also formed at the upper end of the wall surface at the joint between the upper and lower concrete blocks. Next, FIG. 6b shows another embodiment of the waterproof structure, and the difference from that in FIG. 6 is that the recess for fitting the elastic packing 15 is different from that in FIG. The point is that the cross section is formed into a bag shape. Then, as shown in FIG. 6b, the protruding parts of the reinforcing bars 5 of the adjacent block bodies 1, 1 are overlapped, and the overlapped parts are welded and fixed. Next, an elastic packing 15 having a circular cross section is placed below the reinforcing bars 5, and the upper surface of the elastic packing 15 is hammered in with a suitable tool to deform it as shown in FIG. 6b and ensure watertightness. After that, the gap between the adjacent block bodies 1, 1 is filled with fresh concrete.

Next, FIG. 7 is a schematic perspective view of a box culvert employing the structure of the present invention. That is, grooves 2 are formed on both sides of the block body 1, and protrusions 3 and 4 are provided on both sides of the groove 2, with the protrusions 3 located on the outside except for the upper end.
The amount of protrusion is made larger than that of the inner protrusion 4. Therefore, its cross section is the same as that in FIG.
Similarly, a metal body 6 made of an angle material is embedded and fixed in the edge. On the other hand, at the upper end (ceiling), the protrusions located on the outside protrude less than the protrusions on the inside, and a notch is formed into which fresh concrete can be filled from the upper end. A large number of such block bodies 1 are connected in the axial direction. After the metal bodies 6 of the protrusions 3 are welded and fixed to each other from the inner surfaces of adjacent block bodies 1, the respective reinforcing bars 5 are bound or welded. Next, the gap is closed from the inner side with a temporary form, and fresh concrete is filled from the upper end. The construction method is basically the same as that shown in Figure 4.

Next, FIG. 8 shows an embodiment in which the concrete block of the present invention is used as a gutter block. The overall shape of this gutter block is a known one; the lower end is completely open, and the upper end is connected by a pair of upper beams.
A top cover fitting inlet 17 opens in the center. This gutter block is placed on an excavated flat surface with its opening side facing downward, and fresh concrete is poured into the bottom of the block at a slope. The feature of this embodiment of such a gutter block is that grooves 2 are formed on both ends of the side wall, and protrusions 3 are provided on the inner wall side of the gutter, and protrusions 4 are provided on the outer wall side of the gutter. , the inner protrusion 3 protrudes more than the outer protrusion 4. And groove 2
The ends of a large number of reinforcing bars 5 are projected apart from each other, and the reinforcing bars 5 are internally electrically connected.

[0015] In order to construct a side gutter using this side gutter block, the following steps may be taken. First, the area where the gutter will be installed is excavated, the bottom surface is made flat, and chestnut stones are laid down and tamped down. Then, underlay concrete is poured on top of the chestnut stone. Then, after the concrete underlay has hardened, a number of gutter blocks are placed in series thereon. A wedge or the like is then interposed between the lower end of the side wall and the lower inner concrete to align the levels of each block. At the same time, the protrusions 3 of adjacent block bodies 1 are butted against each other, and the metal bodies 6 provided at the edges of the protrusions 3 are welded from the outside of the side gutter. Then, adjacent reinforcing bars 5 are bound together by welding or binding wires, gaps in the outer wall are closed with temporary frames, and fresh concrete is filled into the joints as joint concrete. Then, after waiting for the soil to harden, the soil is backfilled on both sides of the outer wall, and a top cover (not shown) is fitted into the top cover fitting opening 17 to complete the side gutter.

Next, FIG. 9 shows an embodiment in which the present invention is applied to another retaining wall block. That is, grooves 2, protrusions 3, and 4 are formed on both sides of the retaining wall surface, and reinforcing bars 5 are protruded from the grooves 2. In this embodiment, the reinforcing bars 5 are provided protruding only on both sides of the wall surface, but they can also be made to protrude in the vertical direction. It should be noted that the joining method of each of the above embodiments is used for joining parts in all directions, and there is no limit to the number of joining parts.

[0017]

Effects of the Invention The concrete block of the present invention has grooves or recesses formed in the longitudinal direction at the side ends of the block body, and ends of a plurality of reinforcing bars buried in the block body while being connected to each other so as to conduct electricity. Since the blocks are configured to protrude into the groove or the recess, the side ends of the block main body can be quickly and integrally connected to the side ends of other block main bodies via reinforcing bars. In other words, the protrusions 3 formed on the respective side ends of adjacent block bodies are brought into contact with each other, so that positioning can be quickly performed. At the same time, the reinforcing bars that protrude from each other within the groove or recess formed between both blocks can be joined. Therefore, by closing the gap formed on one surface side and filling the groove or recess formed inside with mortar or ready-mixed concrete and hardening, both blocks are integrally connected via reinforcing bars. can do. Moreover, this work can be performed extremely easily and quickly.

Furthermore, according to the invention of claim 1, 2, or 6, one of the protrusions 3 formed on both sides of the groove 2
Since the protrusion height is made higher than the other protrusions 4, a plurality of reinforcing bars protruding from the lower protrusion side to the end of the block can be joined to each other. At the same time, the mortar or ready-mixed concrete filled between adjacent blocks is prevented from coming off in the width direction by both protrusions 3 and 4, thereby forming a stronger joint. Furthermore, it is possible to provide blocks that are easy to join. Next, according to the invention of claim 2, the metal body 6 is buried in the end of the protrusion 3 having a higher protrusion height so that its surface is exposed, and the metal body 6 can conduct electricity to the reinforcing bar 5. Since the metal bodies of adjacent blocks are connected to each other, it is possible to electrically weld the metal bodies 6, 6 between the two metal bodies 6, 6, so that the mortar can be applied between both blocks while each block is positioned and fixed. Alternatively, it becomes possible to fill with ready-mixed concrete, and it is possible to form a structure consisting of a set of precise concrete blocks.

[0019] Furthermore, the invention described in claim 4 is based on the invention described in claim 2.
Since this is a method of joining adjacent blocks using the block body of the invention in section 1, construction is easy and each block can be integrally fixed via reinforcing bars. Further, according to the invention of claim 5, the gap on the side of the convex strip having a low protrusion height is closed by the closing body 7, and the closing body 7
and reinforcing bars 5 are tied together with wire rods or hook bolts, so the closure body can be very easily fixed to the surface of the block body, further facilitating construction using concrete blocks. In addition, the invention as claimed in claim 6 has the structure of the invention as claimed in claim 1, in addition to the structure of the invention as claimed in claim 1, an elastic packing is fitted to the edge of the concave groove 2 side of the convex strip 3 having a higher protrusion height along its longitudinal direction. Since the concave portion 8 is formed and the waterproof layer 9 is provided on the outer periphery of the block body including the concave portion 8, it is possible to create a waterproof structure using this concrete block. Furthermore, in the invention described in claim 7, since the concave portion 8 for fitting the elastic packing is formed in the shape of a second groove in the sixth aspect, watertightness can be further improved and construction can be facilitated.
