Description

[Technical field]

[0001] The present invention relates to a foundation construction method for a block-laid structure using formwork-like blocks having a formwork function, and to a support member for supporting the formwork-like blocks. [Background technology]

[0002] Patent Document 1 discloses a formwork-shaped foundation slab block for concrete block walls which increases work efficiency by eliminating the need to assemble and dismantle formwork when constructing the foundation slab of a concrete block structure, enables construction of the rising part of the foundation without waiting for the concrete to cure, and simplifies the assembly work of the main reinforcement and distribution reinforcement of the foundation slab and the vertical reinforcement of the wall of the block stacked structure, thereby streamlining construction.

[0003] Patent Document 2 discloses a block foundation consisting of concrete blocks joined longitudinally on the ground, concrete independent foundations buried in the ground beneath each joint of the concrete blocks to support the concrete blocks, piles driven into the ground beneath the independent foundations with their upper ends embedded within the independent foundations, and reinforcing bars erected from within the independent foundations and positioned within the joints of the concrete blocks.

[0004] [Patent Document 1] Utility model registration No. 3122098 [Patent Document 2] Japanese Patent Publication No. 8-270270 Summary of the Invention [Problem to be solved by the invention]

[0005] However, although the construction method of Patent Document 1 eliminates the need for assembling and dismantling formwork, it does not provide formwork blocks that serve as foundation erection parts and realize a structure in which the foundation erection parts can be considered equivalent to reinforced concrete construction. Also, the construction method of Patent Document 2 is a method in which concrete blocks are arranged on a concrete independent foundation in the extension direction of the wall, but the concrete independent foundation is relatively heavy, which creates a problem of a large workload.

[0006] In view of the above circumstances, an object of the present invention is to provide a foundation construction method and support member for a block-stacking structure, which can provide formwork-like blocks that serve as the foundation rise portion, and realize a structure in which the foundation rise portion can be regarded as equivalent to a reinforced concrete structure, while also enabling the weight of the support members that support the formwork-like blocks to be reduced. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a foundation construction method for a block-built structure, comprising the steps of: preparing a pouring area for the foundation concrete in the ground at a location where the foundation of the block-built structure is to be built; A process of arranging base reinforcement extending in the extension direction of the foundation and vertical reinforcement located between formwork-like blocks arranged in the extension direction of the foundation within the casting area to form a foundation rise portion; A step of positioning a plurality of support members each having a lower plate portion, a leg portion erected on the lower plate portion, and an upper plate portion supported by the leg portion at predetermined intervals in the extension direction of the foundation within the casting area; placing an end portion of the formwork-like block on the upper plate portion of the support member; pouring concrete into the pouring area and into the formwork blocks; The present invention is characterized by comprising:

[0008] With the above method, a number of formwork-like blocks are arranged on the upper plate portions of the multiple support members, and concrete is poured into the pouring area and into the formwork-like blocks, so that the formwork-like blocks become the foundation rise portion, and this foundation rise portion has a structure that can be considered equivalent to a reinforced concrete structure.

[0009] In a construction method in which base concrete without a foundation standing part is poured, formwork-like blocks are piled on the hardened base concrete, and filling concrete is poured into the formwork-like blocks, the strength of the filling concrete is specified, so that concrete remains due to the unit of fresh concrete order, and it is necessary to dispose of it or return it to the plant. In contrast, in the foundation construction method for block stacking structures according to the present invention, concrete is poured simultaneously in the pouring area and in the formwork-like blocks, so there is no need to wait for the base concrete to harden as described above, and the construction period can be shortened. In addition, a certain amount of concrete can be secured, so that returned concrete can be reduced and environmentally friendly.

[0010] In addition, the support member that supports the formwork-shaped block comprises a lower plate portion, legs erected on the lower plate portion, and an upper plate portion supported by the legs, so that it is possible to make it lighter than a support member made by solidifying concrete, thereby reducing the workload.

[0011] In the foundation construction method for the block stacking structure, the work of erecting the preparatory bar to support the vertical reinforcement may be performed, and the work of providing the support member in a manner to avoid interference between the preparatory bar and the vertical reinforcement may be performed. For example, two support members may be arranged close to the preparatory bar, with one support member supporting an end side of one formwork-like block and the other support member supporting an end side of the other formwork-like block.

[0012] In the foundation construction method for a block-piled structure, the lower plate and the upper plate of the support member may be formed with insertion parts for passing the prepared bar and the vertical reinforcement. With this, the prepared bar and the vertical reinforcement are positioned at the center of one support member, and one end of the support member can support one end of a formwork-like block, and the other end can support one end of another formwork-like block.

[0013] A run-out stopper that contacts the formwork-shaped block to suppress displacement of the formwork-shaped block may be disposed in the casting area, and after concrete is poured into the casting area and the formwork-shaped block, the run-out stopper may be removed before the concrete hardens. This makes it possible to suppress the formwork-shaped block from shifting due to the pouring pressure of the concrete.

[0014] The support members may be assembled in the casting area. For example, each lower plate of the support member may be placed on the upper ground by passing the insertion portion of the lower plate through a prepared bar previously placed in the casting area, and after arranging vertical reinforcement or the like, the legs and the upper plate may be assembled to each lower plate.

[0015] The support member may be placed in the casting area by passing the prepared bar and the vertical reinforcement through the insertion portion of the assembled support member. For example, a notch is formed as the insertion portion in the lower plate portion and the upper plate portion of the support member, and the support member can be moved laterally through the notch to position the prepared bar and the vertical reinforcement at the center of the lower plate portion and the upper plate portion.

[0016] In addition, the support member of the present invention is a support member that supports the end of a formwork-shaped block within a concrete pouring area formed in the ground at the location where the foundation of a block-stacking structure is to be constructed during the construction of the foundation of the block-stacking structure, thereby separating the formwork-shaped block from the bottom surface of the ground, and is characterized in that it comprises a lower plate portion, legs that are erected at multiple positions on the lower plate portion offset from the center of the lower plate portion, and an upper plate portion supported by the legs, and is characterized in that an insertion portion for passing a reinforcing bar is formed at least on the center side of each of the lower plate portion and the upper plate portion.

[0017] In the support member, the insertion portion of the lower plate portion may be an opening, a notch or a dividing slit, and the insertion portion of the upper plate portion may be an opening or a notch.

[0018] In the support member, the upper plate portion may include a rising portion facing an edge side of the formwork-shaped block. Effect of the Invention

[0019] According to the present invention, by constructing the foundation rise portion using formwork-shaped blocks, it is possible to realize a structure in which the foundation rise portion can be considered equivalent to a reinforced concrete structure, and further, by pouring concrete on the foundation side and the formwork-shaped block side simultaneously, it is possible to shorten the construction period and reduce the amount of returned concrete, as well as to easily reduce the weight of the support members that support the formwork-shaped blocks.

[0021] (Embodiment 1) Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. As shown in Figures 1 and 2, in the foundation construction method of the embodiment, a pouring area 21 for concrete that will become the foundation 11 is prepared on the ground 2 at a location where the foundation 11 of a block-piled structure 1, such as a block wall, is to be constructed by piling up blocks. In this example, crushed stone 211 is laid on the ground 2 in the pouring area 21, and a concrete retaining frame 212 is placed on the side of the pouring area 21. The concrete retaining frame 212 is composed of, for example, piles driven into the crushed stone 211 and a frame plate supported by the piles.

[0022] Then, the prepared bars 3 are inserted into the crushed stone 211 at a predetermined interval (for example, 400 mm pitch) in the extension direction of the foundation 11 and erected. The prepared bars 3 are not particularly shown on the reinforcement drawing of the foundation 11, but are rod-shaped materials made of linear reinforcing bars or other materials that are inserted into the ground 2 side to smoothly lay the reinforcement of the foundation 11. Thereafter, the lower plate part 41 of the support member 4 is arranged while avoiding interference with the prepared bars 3. For example, an insertion part 41a consisting of a circular or square opening is formed in the center of the lower plate part 41, which is substantially rectangular, and the prepared bar 3 is passed through this insertion part 41a, and the lower plate part 41 is placed on the crushed stone 211.

[0023] Next, as shown in Fig. 3 and Fig. 4, in the casting area 21, the base reinforcement 111 extending in the extension direction of the foundation 11 and the vertical reinforcement 112 positioned between the formwork-like blocks 5 arranged in the extension direction of the foundation 11 to form the foundation rising part are arranged. For example, the worker ties the base reinforcement 111, which is temporarily placed on a regular hexahedron made of concrete placed on the crushed stone 211 in the casting area 21 to ensure concrete cover, to the preparation bar 3 with a wire. The vertical reinforcement 112 has a substantially L-shape, and the worker ties the vertical bar portion of the vertical reinforcement 112 to the preparation bar 3 with a wire and ties the other base reinforcement 111 to the tip side of the horizontal bar portion with a wire.

[0024] Then, the legs 42 and the upper plate 43 of the support member 4 are arranged while avoiding interference with the prepared bar 3, the base reinforcement 111, and the vertical reinforcement 112. The horizontal bar parts of the base reinforcement 111 and the vertical reinforcement 112 are passed through the lower side of the upper plate 43. The support member 4 is made of, for example, metal, and supports the end of the formwork-shaped block 5 to separate the formwork-shaped block 5 from the bottom surface of the ground 2. The height of the support member 4 (the position of the upper plate 43) is approximately the same as the height of the foundation 11, and supports the formwork-shaped block 5 at the height of the top end of the foundation 11. In this construction example, the support member 4 is assembled in the casting area 21, so that a plurality of the support members 4 are positioned at predetermined intervals in the extension direction of the foundation 11.

[0025] The assembly procedure for the support member 4 is not limited in any way, and the legs 42 may be attached to the lower plate portion 41 within the pouring area 21, or the lower plate portion 41 with the legs 42 attached may be placed in the pouring area 21 and then the upper plate portion 43 may be attached to the legs 42, or the upper plate portion 43 may be attached to the legs 42 and then attached to the lower plate portion 41 placed in the pouring area 21.

[0026] For example, the legs 42 are, for example, rod-shaped members erected at a plurality of positions on the lower plate 41 that are offset from the center of the lower plate 41, and two legs 42 are provided spaced apart in a direction perpendicular to the extension direction of the foundation 11. The prepared bar 3 is located between the two legs 42, and the two legs 42 and the prepared bar 3 overlap when viewed from a direction perpendicular to the extension direction, and the vertical reinforcement bars 112 do not appear to overlap.

[0027] The upper plate portion 43 is substantially rectangular, and an insertion portion 43a consisting of a circular or rectangular opening is formed at the center. The upper plate portion 43 also has a rising bent portion 43b (rising portion) that faces the edge side of the formwork-shaped block 5 and prevents the formwork-shaped block 5 from slipping. For example, the lower plate portion 41 and the upper plate portion 43 are formed with holes into which the tip convex portions of the legs 42 are fitted, and the support member 4 can be assembled by inserting the tip convex portions into the holes. The upper plate portion 43 is located below the upper end surface of the concrete retaining frame 212 and is disposed in contact with the concrete retaining frame 212 on one side.

[0028] Next, the ends of the plurality of formwork-shaped blocks 5 are placed on the upper plate portions 43 of the plurality of support members 4. The end faces of the formwork-shaped blocks 5 are concave, and the prepared bars 3 and the vertical bars of the vertical reinforcements 112 are located in the concave portions. That is, the prepared bars 3 are inserted between the formwork-shaped blocks 5. Next, empty mortar 213 is placed under the lower plate portion 41 to adjust the level of the upper ends of the formwork-shaped blocks 5 and to adjust the horizontality. Since the upper plate portion 43 has a rising bent portion 43b, the formwork-shaped blocks 5 are less likely to slip off during this adjustment work.

[0029] Next, as shown in Figures 5 and 6, a sway stopper 6 is placed in contact with the formwork-shaped block 5 to prevent the formwork-shaped block 5 from shifting when concrete is poured. For example, the sway stopper 6 is made of a rebar bent into an inverted U-shape with an open bottom to avoid interference with the base reinforcement 111, and is positioned so as to contact the concrete retaining frame 212 on one side with the tip of the bottom side inserted into the crushed stone 211. The sway stopper 6 is also higher than the height of the foundation 11.

[0030] Next, concrete C is poured into the pouring area 21 and the formwork-like block 5, and the vibration stopper 6 is removed before the concrete C hardens. Then, once the concrete C has hardened, the concrete retaining frame 212 and the pile are removed.

[0031] With the above construction method, multiple formwork-like blocks 5 are lined up on each upper plate portion 43 of the multiple support members 4, and concrete is poured into the pouring area 21 and into the formwork-like blocks 5, so that the formwork-like blocks 5 become the foundation riser portion, and this foundation riser portion has a structure that can be considered equivalent to a reinforced concrete structure.

[0032] Here, in a construction method in which base concrete without a foundation standing part is poured, formwork-like blocks are piled on the hardened base concrete, and filling concrete is poured into the formwork-like blocks, the strength of the filling concrete is specified, so that concrete remains due to the unit of fresh concrete order, and it is necessary to dispose of it or return it to the plant. In contrast, in the foundation construction method for a block stacking structure according to the embodiment, concrete C is poured simultaneously in the pouring area 21 and the formwork-like blocks 5, so there is no need to wait for the base concrete to harden as described above, and the construction period can be shortened. In addition, a certain amount of concrete C can be secured, so that returned concrete can be reduced and environmentally friendly.

[0033] In addition, the support member 4 supporting the formwork-shaped block 5 comprises a lower plate portion 41, legs 42 standing on this lower plate portion 41, and an upper plate portion 43 supported by the legs 42. Therefore, it is possible to make the support member lighter than a support member made by solidifying concrete, and the workload can be reduced.

[0034] In addition, the lower plate portion 41 and the upper plate portion 43 of the support member 4 are formed with insertion portions 41a, 43a for passing the prepared bar 3 and the vertical bar portion of the vertical reinforcement 112 therethrough. Therefore, the prepared bar 3 can be positioned at the center of one support member 4, and one end side of the one support member 4 can support an end side of one formwork-shaped block 5, and the other end side can support an end side of another formwork-shaped block 5.

[0035] In addition, a vibration stopper 6 is arranged in contact with the formwork-shaped block 5 to prevent the formwork-shaped block 5 from shifting out of position, so that the formwork-shaped block 5 can be prevented from shifting due to the pouring pressure of the concrete C.

[0036] (Embodiment 2) Hereinafter, other embodiments of the present invention will be described with reference to the attached drawings. In the first embodiment, the preparation bar 3 is inserted, the lower plate part 41 is placed on the ground 2 in advance through the insertion part 41a of the preparation bar 3, the base reinforcement 111 and the vertical reinforcement 112 are arranged, and then the support member 4 is completed. In the construction method of the second embodiment, as shown in FIG. 7, the preparation bar 3 is inserted, the base reinforcement 111 and the vertical reinforcement 112 are arranged, and then the unfinished or assembled support member 4 is positioned in the casting area 21, and the formwork-like block 5 is placed on the support member 4.

[0037] In this embodiment 2, as shown in Fig. 8(A), a notch 41b is formed as an insertion portion in the lower plate portion 41 of the support member 4, which reaches the center side of the lower plate portion 41. This notch 41b is cut in the extension direction of the foundation 11. Alternatively, as shown in Fig. 8(B), a dividing slit 41c is formed as an insertion portion in the lower plate portion 41, and the lower plate portion 41 is divided into two. This dividing slit 41c passes in the extension direction of the foundation 11. In the upper plate portion 43, an insertion portion 43a consisting of a notch similar to the notch 41b is formed, or an insertion portion 43a consisting of a circular or rectangular opening is formed.

[0038] The assembly procedure for the support member 4 may involve attaching the legs 42 to the lower plate portion 41 within the pouring area 21, or the lower plate portion 41 with the legs 42 attached may be placed in the pouring area 21 and then the upper plate portion 43 may be attached to the legs 42, or the upper plate portion 43 may be attached to the legs 42 and then attached to the lower plate portion 41 placed in the pouring area 21.

[0039] Furthermore, when a support member 4 is used in which the upper plate portion 43 has the insertion portion 43a formed by a notch and the lower plate portion 41 has the notch 41b or the dividing slit 41c, after the preparation bar 3, the base reinforcement 111, and the vertical reinforcement 112 are installed, the assembled support member 4 can be moved laterally via the notch 41b, etc., to position the preparation bar 3, etc., at the center side of the lower plate portion 41 and the upper plate portion 43. That is, the preparation bar 3, etc. can be passed through the upper and lower insertion portions of the assembled support member 4, and the support member 4 can be placed in the casting area 21. The assembled support member 4 can also be firmly fixed to each other by welding the lower plate portion 41, the leg portion 42, and the upper plate portion 43.

[0040] FIG. 9 illustrates various types of support members 4. In the support member 4 shown in FIG. 9(A), a rectangular opening insertion portion 41a is formed at the center of the lower plate portion 41, and a rectangular opening insertion portion 43a is formed at the center of the upper plate portion 43. The legs 42 are not limited to being made of two rod-shaped members, and may be bent into an approximately U-shape and connected to the two legs 42 at a connecting portion on the upper side. In addition, the upper plate portion 43 has the centers of both edges bent vertically downward, and the tip side of the bent portion has a folded portion 43c bent horizontally inward, thereby increasing rigidity, so that the portion that receives the formwork-shaped block 5 is less likely to deform. In addition, if an opposing notch 43d is formed at the tip of the horizontally bent portion of the folded portion 43c, the upper side of the reinforcing bar bent into the approximately U-shape can be fitted into the opposing notch 43d. The connecting portion of the substantially U-shaped leg portion 42 is formed with a bent portion so as not to cross the insertion portion 41a.

[0041] In the support member 4 shown in Fig. 9(B), a circular opening insertion portion 41a is formed at the center of the lower plate portion 41, and a circular opening insertion portion 43a is formed at the center of the upper plate portion 43. In the support member 4 shown in Fig. 9(C), the lower plate portion 41 has a notch 41b as an insertion portion, and the upper plate portion 43 has a notched insertion portion 43a. In the support member 4 shown in Fig. 9(D), the lower plate portion 41 has a division slit 41c as an insertion portion, and the upper plate portion 43 has a notched insertion portion 43a.

[0042] Furthermore, the shape of the foundation 11 is not limited to the above. As shown in Fig. 10, the intervals between the concrete retaining frames 212 that form the casting area 21 may be widened, and the formwork-like block 5 may be positioned at the center of the wide foundation 11. When making a wide foundation 11 in this manner, the run-out stoppers 6 are placed on both edge sides of the formwork-like block 5.

[0043] 11, the casting area 21 may be formed wide by excavating the ground 2, and the formwork-like block 5 may be located at the center of the wide foundation 11. When creating a wide foundation 11 in this manner, the runout stoppers 6 are placed on both edge sides of the formwork-like block 5.

[0044] 12, the casting area 21 may be formed wide by excavating the ground 2 and forming a concrete retaining frame 212 on one side, and the formwork-like block 5 may be located at the center of the wide foundation 11. When creating a wide foundation 11 in this way, the runout stoppers 6 are placed on both edge sides of the formwork-like block 5.

[0045] In addition, the swing fastener 6 is not limited to a structure that contacts the lower side of the formwork-like block 5. For example, as shown in FIG. 13(A), a hook-shaped swing fastener 6A having a vertical bar portion and an upper horizontal bar portion may be used, and the upper part of the formwork-like block 5 may be restrained by the upper side of the vertical bar portion and the upper horizontal bar portion. Alternatively, as shown in FIG. 13(B), a straight bar-shaped swing fastener 6B may be used, and this swing fastener 6B may be inserted obliquely into the ground 2 so as to contact the upper corner of the formwork-like block 5, thereby restraining the upper part of the formwork-like block 5. Alternatively, as shown in FIG. 13(C), a swing fastener 6C having a vertical bar portion and an upper diagonal bar portion may be used, and the upper diagonal bar portion of this swing fastener 6C may be inserted into the ground 2 so as to contact the upper corner of the formwork-like block 5, thereby restraining the upper part of the formwork-like block 5.

[0046] In the above example, the preparation bar 3 is positioned at the center of one support member 4, one end of the support member 4 supports an end of one formwork-shaped block 5, and the other end supports an end of another formwork-shaped block 5, but this is not limited to the above. For example, two support members may be disposed close to the preparation bar 3, one support member supports an end of one formwork-shaped block 5, and the other support member supports an end of the other formwork-shaped block 5.

[0047] Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
