Specifically, the foundation gap prevention plate holder 10 is attached at a position where substantially half of the foundation gap prevention plate 7 held by the foundation gap prevention plate holder 10 is buried in the solid foundation 4. Next, an outer mold (not shown) is installed on the discarded concrete 3 so that the lower half of the foundation gap prevention plate 7 and the foundation gap prevention plate holder 10 are embedded in the outer mold. The solid foundation 4 is formed by placing concrete.

  In addition, in FIG. 1, although the foundation clearance prevention board 7 is attached to the indoor side rather than the reinforcing bar 6, you may attach to the outdoor side. When installed on the indoor side, the foundation gap prevention plate 7 is not only received by the foundation gap prevention plate 7 but also the stress acting on the outdoor side when the solid foundation concrete is poured. It is more preferable because it can be received by the reinforcing bars 6 in the direction.

  Thereafter, an inner mold (not shown) is installed on the solid foundation 4, and concrete is placed between the inner mold and the outer mold to form the cloth foundation 5. The portions of the reinforcing bar 6, the foundation gap prevention plate 7, and the foundation gap prevention plate holder 10 that protrude from the upper surface of the solid foundation 4 are embedded in the fabric foundation 5. As described above, the foundation structure 1 is completed.

Next, details of the foundation gap prevention plate 7 will be described.
The base gap prevention plate 7 is formed of a resin material or a metal material, and maintains strength even when it is thinned. It is easy to bend and process, and can be carried in a rolled state. It is preferable to form with an advantageous metal material. Specifically, for example, one made of a hot dip galvanized steel sheet can be exemplified. The width of the foundation gap prevention plate 7 is not particularly limited, and may be 3 to 8 cm as long as the joint between the solid foundation and the fabric foundation can be surely crossed in consideration of construction errors. Is preferable, and it is more preferable to set it as 5-6 cm. The plate | board thickness of the base clearance gap prevention board 7 is not specifically limited, It can determine suitably with the kind of the material, A plate-shaped thru | or sheet-like thing can be used. For example, if it is a metal material, even if it makes it thin, since intensity | strength is maintained and a desired role can be maintained, it is preferable to set it as 0.1-1 mm, and it is set as 0.1-0.5 mm thin plate shape. Is particularly preferred. By using a thin plate, for example, it is possible to make it compact even when it is rolled up to a length of 15 to 25 m, and it is easy to carry, and it can be easily folded and placed along the outer periphery during use. it can. Moreover, it is preferable to provide the mark (line) used as the standard of the height at the time of pouring the concrete for solid foundations in the center of the width direction of the foundation clearance prevention board 7. FIG. Moreover, it is preferable to provide a hole and an unevenness | corrugation in the base clearance gap prevention board 7 in order to improve adhesiveness with concrete. In addition, when providing a hole, it provides in the position which avoided the width direction center part of the base clearance gap prevention board 7. FIG.

Next, the details of the foundation clearance prevention plate holder 10 will be described.
As shown in FIGS. 2 to 4, the foundation clearance prevention plate holder 10 includes a gripping portion 20 for gripping the longitudinal reinforcing bars 6 and a clamping portion 30 for clamping the foundation clearance prevention plate 7. . In the following description, the vertical direction and the horizontal direction in a state in which the foundation gap prevention plate holder 10 is attached to the vertical reinforcing bar 6 are simply referred to as the vertical direction and the horizontal direction.

  The base clearance prevention plate holder 10 is formed of two kinds of materials, and has a hard part and a soft part softer than the hard part. For the hard portion, a resin material such as polypropylene, polyethylene, or vinyl chloride or a metal material is used, but it is preferable to use a resin material that is lightweight and easy to mold. Various kinds of synthetic rubber, natural rubber, silicon, and the like can be widely used for the soft part. For example, those having a durometer A hardness (JIS K6253) of 50 degrees or less can be preferably used. The soft part has a higher frictional resistance against the basic gap prevention plate 7 than the hard part. Moreover, although the color of a hard part and a soft part differs, the same color may be sufficient.

  The grip part 20 is composed of a hard part. The grip part 20 includes two pairs of leg parts 21 that protrude from the clamping part 30 (specifically, a back surface of a fixed piece 31 described later). The reinforcing bar 6 is gripped between the pair of leg portions 21. The two pairs of leg portions 21 are arranged side by side in the vertical direction (longitudinal direction of the reinforcing bars 6). The pair of leg portions 21 are disposed at positions that do not face each other with the reinforcing bar 6 interposed therebetween. The pair of leg portions 21 are formed symmetrically.

  The leg portion 21 includes a contact portion 22 and an open piece 23. The contact part 22 is a part for gripping the reinforcing bar 6 and is connected to the holding part 30. As shown in FIG. 4, the inner surface (rebar 6 side) of the contact portion 22 is formed in an arc shape along the outer peripheral surface of the rebar 6.

  The open piece 23 is connected to the contact portion 22 and is provided at the protruding tip of the leg portion 21. As shown in FIG. 4, the inner surface (reinforcing bar 6 side) of the open piece 23 is formed so as to move away from the open piece 23 that forms a pair as it approaches the protruding tip. That is, the distance between the open pieces 23 of the pair of leg portions 21 increases as the distance from the projecting tip increases.

  In order to attach the grip 20 to the rebar 6, the rebar 6 is pushed between the pair of legs 21. Thereby, the space | interval of a pair of leg part 21 is expanded, and the reinforcing bar 6 is arrange | positioned between the contact parts 22 of a pair of leg part 21, and is hold | gripped by the elastic restoring force of the leg part 21. FIG. Thus, since the holding part 20 can be attached by pushing into the reinforcing bar 6, the attaching operation to the reinforcing bar 6 can be easily performed.

  Moreover, since the leg part 21 has the open piece 23 in the protrusion front end side rather than the part (contact | abutting part 22) which grasps the reinforcing bar 6, the open piece 23 is pressed and the space | interval of a pair of leg part 21 is expanded. Thereby, the attachment work to the reinforcing bar 6 can be performed more easily than the case where there is no open piece 23. Moreover, since the space | interval of a pair of leg part 21 can be extended by putting a finger | toe on an open piece after attaching to the reinforcing bar 6, an adjustment operation | work of an attachment position or the operation | work removed from a reinforcement bar 6 when an attachment position is wrong is easy. Can be done.

  Moreover, since the space | interval of the open pieces 23 of a pair of leg part 21 becomes so large that it approaches the protrusion front-end | tip, by pushing the reinforcing bar 6 between the open pieces 23 of a pair of leg parts 21, the open piece 23 The distance between each other can be expanded smoothly. Therefore, the reinforcing bar 6 can be easily disposed on the contact portion 22.

  In addition, since the pair of leg portions 21 are disposed at positions that do not face each other with the reinforcing bar 6 interposed therebetween, compared to the case where the pair of leg portions 21 are disposed to face each other, the inner side of the pair of leg portions 21 (the reinforcing bar 6 It is easy to hook your finger on the side. Therefore, it is possible to easily adjust the attachment position after being attached to the reinforcing bar 6 or to remove it from the reinforcing bar 6 when the attachment position is wrong.

  In addition, since two pairs of the leg portions 21 are provided, the foundation gap prevention plate holder 10 can be attached to the rebar 6 in a more stable and stable state as compared with the case where only one set is provided. , Can prevent displacement.

  Next, the clamping part 30 is demonstrated. The clamping unit 30 has a fixed piece 31 and a movable piece 32. A gap in which the foundation gap prevention plate 7 is disposed is formed between the fixed piece 31 and the movable piece 32, and the foundation gap prevention plate 7 is sandwiched between the fixed piece 31 and the movable piece 32. .

  The fixed piece 31 is a rod-like member having a substantially semicircular cross section that extends in the vertical direction. On the back surface of the fixed piece 31 (surface opposite to the movable piece 32), two pairs of leg portions 21 are provided so as to protrude. The reinforcing bars 6 held by the pair of leg portions 21 are in contact with the back surface of the fixed piece 31. A protrusion 33 is provided on the upper end of the fixed piece 31.

The lower half of the fixed piece 31 and the protrusion 33 are formed of a hard part. The upper half of the fixed piece 31 (excluding the protrusion 33) is composed of a hard portion at the center, and the periphery (surface) is indicated by a soft portion 31a (dot hatching in FIGS. 3 and 4). ).
An uneven shape is formed on the surface of the soft portion 31a that is in contact with the basic gap prevention plate 7. Each of the concave and convex portions having the concavo-convex shape extends in the horizontal direction.

  The movable piece 32 is a substantially bar-like member having substantially the same length as the fixed piece 31. The lower end of the movable piece 32 is connected to the lower end of the fixed piece 31. A U-shaped groove 34 is formed by the lower end of the movable piece 32 and the lower end of the fixed piece 31. The gap of the groove 34 is slightly larger than the thickness of the basic gap prevention plate 7 and is substantially constant in the vertical direction.

  The movable piece 32 has a thin hinge portion 35 that is slightly thinner than the other portions at a portion slightly below the central portion in the longitudinal direction. Therefore, the upper part of the movable piece 32 above the thin hinge portion 35 can swing around the thin hinge portion 35. Further, the thin-walled hinge portion 35 is bent so that the upper portion of the thin-walled hinge portion 35 is separated from the fixed piece 31 when no force is received. The lower portion of the thin hinge portion 35 constitutes the U-shaped groove portion 34 described above, and the depth of the groove portion 34 is the length from the lower end of the thin hinge portion 35 to the bottom surface of the groove portion 34.

  At the upper end of the movable piece 32, a hook 36 that is locked to the protrusion 33 of the fixed piece 31 is provided. The hooks 36 and the projections 33 allow the upper ends of the fixed piece 31 and the movable piece 32 to be engaged and disengaged.

As for the movable piece 32, the thin hinge part 35 and the part below the thin hinge part 35 are comprised by the hard part. Further, the hook 36 of the movable piece 32 is also composed of a hard part. The upper part of the movable piece 32 above the thin hinge part 35 (excluding the hook 36) has a central part made of a hard part, and its periphery (surface) is a soft part 32a (in FIGS. 3 and 4). It is covered with dot hatching).
An uneven shape is formed on the surface of the soft portion 32a that comes into contact with the basic gap prevention plate 7. Each of the concave and convex portions having the concavo-convex shape extends in the horizontal direction.

  Further, in a state where the hook 36 and the protrusion 33 are locked, the gap between the thin hinge part 35 in the clamping part 30 (the soft part 31a of the fixed piece 31 and the soft part 32a of the movable piece 32) is the basis. It becomes smaller than the thickness of the gap prevention plate 7. Therefore, in a state where the hook 36 and the protrusion 33 are locked and the basic gap prevention plate 7 is clamped by the clamping part 30, the soft part 31a of the fixed piece 31 and the soft part 32a of the movable piece 32 are elastically deformed. ing.

  When attaching the foundation gap prevention plate 7 to the clamping part 30, first, the foundation gap prevention plate 7 is inserted into the U-shaped groove 34. The foundation clearance preventing plate 7 is held along the fixed piece 31 by the groove 34. With the foundation gap prevention plate 7 temporarily placed in the groove 34 in this way, the upper portion of the movable piece 32 is pressed toward the fixed piece 31 to deform the thin hinge portion 35, and the movable piece 32 and the fixed piece 31. The base gap prevention plate 7 is sandwiched between the two. Then, the hook 36 is hooked on the protrusion 33.

  In this way, by disposing the basic gap prevention plate 7 in the gap between the fixed piece 31 and the movable piece 32 and locking the fixed piece 31 and the movable piece 32, between the fixed piece 31 and the movable piece 32. Thus, the foundation gap prevention plate 7 can be clamped, so that the foundation gap prevention plate 7 can be easily attached.

  Moreover, since the groove part 34 can hold | maintain the foundation clearance prevention board 7, when attaching the foundation clearance prevention board 7, the fixed piece 31 and the movable piece 32 in the state which inserted the foundation clearance prevention board 7 in the groove part 34 and temporarily set | placed. The operation | work which latches can be performed. Therefore, the attachment work of the foundation clearance prevention plate 7 can be performed more easily.

  Moreover, since the U-shaped groove part 34 is not comprised by the soft part with a large frictional resistance, the base clearance gap prevention board 7 can be smoothly inserted in the groove part 34. FIG. Therefore, compared with the case where the groove part 34 is comprised with the soft part, attachment workability | operativity can be improved.

  In addition, the thin-walled hinge portion 35 is bent so that the upper portion of the thin-walled hinge portion 35 is separated from the fixed piece 31 in a state where no force is received. Therefore, when the base gap prevention plate 7 is inserted into the groove portion 34, It is possible to prevent the upper half of the movable piece 32 from interfering.

  Further, since the portion above the thin hinge portion 35 in the movable piece 32 can swing around the thin hinge portion 35, the foundation gap prevention plate 7 is securely sandwiched between this portion and the fixed piece 31. be able to.

  Further, since the foundation gap prevention plate holder 10 holds and holds the foundation gap prevention plate 7, the foundation gap prevention plate 7 can be prevented from being displaced.

  Moreover, since the part of the surface which clamps the foundation clearance prevention board 7 is comprised by the soft part which is easy to elastically deform, the foundation clearance prevention board holder 10 can clamp the foundation clearance prevention board 7 stably. And can prevent displacement. In particular, even when a metal thin plate is used as the base gap prevention plate 7, it can be stably held without slipping or shifting.

  Moreover, in this embodiment, the part above the thin hinge part 35 in the clamping part 30 is comprised by the soft parts 31a and 32a. Since the portion above the thin hinge portion 35 in the sandwiching portion 30 is a portion that can securely sandwich the foundation gap prevention plate 7 as described above, by configuring this portion as a soft portion, the foundation gap prevention plate 7 Can be held more stably.

  Moreover, since the uneven | corrugated shape is formed in the surface contact | abutted to the base clearance gap prevention board 7 of the soft parts 31a and 32a, the foundation clearance gap prevention board 7 can be clamped still more stably.

  Further, since the colors of the hard portion and the soft portions 31a and 32a are different, there is a color boundary line at the substantially central portion in the longitudinal direction of the sandwiching portion 30. This boundary line can be used as a measure of the height when pouring concrete for solid foundation.

In the foundation structure 1 of the present embodiment, the foundation gap prevention plate 7 can be simply arranged so that the joint between the solid foundation 4 and the fabric foundation 5 intersects. As a result, the base gap prevention plate holder 10 holds the gap and the gap between the solid foundation 4 and the fabric foundation 5 is blocked by the foundation gap prevention plate 7 embedded in the solid foundation 4 and the fabric foundation 5. It is possible to prevent white ants and moisture from entering the floor from the outside.
In addition, since the foundation gap prevention plate holder 10 and the foundation gap prevention plate 7 are arranged in the process of forming the solid foundation 4 and the fabric foundation 5, the foundation surface is soiled as in the case of using an antifungal agent or a waterproof sheet. It is not necessary to remove dust and dust, and the installation work can be simplified.
