  TECHNICAL FIELD The present invention relates to a formwork width stopper and a locking structure in the formwork width determining tool, and more particularly to a width stopper and a formwork for holding a formwork used at the time of placing concrete at a predetermined interval. The present invention relates to a structure for locking.

  As described in Patent Document 1, as a conventional formwork width determining tool, as described in the conventional formwork width stopper, an outer locking piece in which both ends of a belt-like plate body are bent, and a plate body It was comprised with the inner side locking piece which cut and raised a part of. However, in the case of the configuration as described above, since the end of the mold is merely fitted in the middle of the both locking pieces, there is a gap between the both locking pieces and the mold. In the case where this occurs, there is a problem that the formwork width stopper is easily detached.

  On the other hand, as a structure for solving the above-mentioned problems, after forming one end of the width stopper main body at a right angle to form an outer locking piece, and further bending toward the other end, it becomes a U shape. A configuration in which a narrow bendable portion is provided at the other end has been proposed (see Patent Document 2).

JP 2002-242430 A (FIG. 4) Japanese Patent Laid-Open No. 5-1472

  However, the technique disclosed in Patent Document 2 is to weld a foldable portion inside the outer locking piece, and the foldable portion is formed narrow (elongated), Although it is possible to easily and freely bend the foldable portion, the folding position is not stable, and the operator has caused variations in the folded state. In addition, since the foldable part is narrow (elongated), the bending direction is also free and may be bent in a twisted state and supported by a point with respect to the edge of the formwork There was sometimes. Furthermore, since the overall width of the mold is determined by a large number of mold width determining tools, since each of the mold width determining tools is bent and locked, When the bending work is complicated and there is a portion that is not bent, there is a risk that the forming of the mold at the portion may be insufficient.

  The present invention has been made in view of the above-described points, and an object of the present invention is to provide a locking structure that eliminates the need for bending work of the foldable portion and to use this locking structure. It is providing the width determination tool which can lock a formwork simply by this.

  Therefore, the present invention related to the locking structure in the formwork width stopper is a formwork width stopper provided with an outer locking piece that is provided at the tip of the long width determining body and regulates the position outside the formwork. A locking structure for locking an end portion of the formwork with the outer locking piece, wherein the outer locking piece is continuous with the width determining body and the other end of the width determining body. A width-determining region that is erected so that a mold contact surface portion is formed toward the side, a cut-out region that is provided by cutting out a part of the width-determining region, and the mold through the cut-out region And a locking member provided so as to be capable of appearing and retracting with respect to the surface of the frame contact surface portion.

  According to the above configuration, the width determining region (particularly the mold contact surface portion) of the outer locking piece formed at the front end of the width determining main body abuts the end of the mold, so that the outside of the mold is outside. In this state, the locking member protrudes to the mold contact surface portion through the notch region, so that the mold can be locked. Since the locking member can be projected and retracted with respect to the mold frame contact surface portion, when the end portion of the mold frame is brought into contact with the mold frame contact surface portion or when the state is released, the lock member is locked. The member can be in a state of sunk from the mold contact surface portion.

  Further, the present invention related to the locking structure for the width stopper for the formwork is provided with an outer locking piece that is provided at the tip of the long width stopper main body and regulates the position outside the mold, and the outer locking piece. An end portion of the mold frame provided with an inner locking piece that is provided at a position having a predetermined distance from the width stop body toward the longitudinal center of the width stopper body and regulates the position inside the mold frame A locking structure for locking the outer locking piece by the outer locking piece, the outer locking piece being continuous with the width determining body and having a mold contact surface portion formed toward the inner locking piece. A width-determining area standing upright, a notch area provided by cutting out a part of the width-determining area, and being provided so as to be able to protrude and retract with respect to the surface of the mold contact surface portion through the notch area And a locking member.

  According to the said structure, the edge part of a formwork will be determined by being inserted between an inner side locking piece and an outer side locking piece, and in the positioned state, a locking member is By projecting with respect to the mold contact surface portion of the outer locking piece, the mold can be locked. And since the locking member can be projected and retracted with respect to the formwork contact surface part, it can be made to protrude from the formwork contact surface part only when it should be locked.

  In both of the above inventions, the locking member can be configured to include a locking member main body in which a base is supported by the width determining main body, and a locking protrusion provided at the tip thereof. When the locking member main body is elastically deformed, the locking projection can be configured so as to be able to protrude and retract with respect to the surface of the formwork contact surface portion via the cutout region.

  According to the above configuration, the locking member is provided integrally with the width determining main body by the locking member main body. And since the latching protrusion can be projected and retracted in the mold contact surface part by elastically deforming the latch member main body, the latch protrusion can be projected at a predetermined position of the mold contact surface part. Further, if the locking projections are not elastically deformed, the state of mold locking by the locking projections can be stabilized.

  Furthermore, in each of the above inventions, the locking member can be configured such that the locking protrusion is urged so as to protrude from the surface of the mold contact surface portion through the notch region.

  According to the above configuration, if an external force in a specific direction (a direction against urging) does not act on the locking member body or the locking protrusion, the locking protrusion protrudes from the mold contact surface portion by the urging force. When this state is maintained and the mold is locked, the locked state of the mold is continued.

  Moreover, in each said invention, all or one part of the said locking member can be comprised with a spring steel or a synthetic resin. In this case, the entire locking member may be made of spring steel or synthetic resin, but a part thereof (for example, only the locking member main body or the locking protrusion) may be made of spring steel or synthetic resin. .

  According to the above configuration, for example, when the locking member body is made of spring steel or synthetic resin, it can be urged against the locking projections by the elastic force of the material. Further, when the locking projection is made of spring steel or synthetic resin, even if the locking projection comes into contact with the edge of the mold, it does not easily plastically deform. It is possible to suppress the occurrence of defects. Further, when the whole is made of synthetic resin, a member having a desired shape can be easily manufactured by an injection molding method or the like.

  The present invention can be conceived of a formwork width determining tool provided with the above-described locking structure. That is, in the width stopper for the formwork provided at both ends of the long width determining body and provided with outer locking pieces for regulating the position outside the mold, at least one outer locking piece is the width determining body. A width-determining region that is erected so that the formwork contact surface portion is formed toward the other end of the width-determining body, and a notch region that is provided by cutting out a part of the width-determining region. And a locking member provided so as to be able to project and retract with respect to the surface of the mold contact surface portion through the notch region.

  In the case where the formwork width determining tool is used as described above, since the locking structure is used in at least one outer locking piece, the other outer locking piece has a conventional locking structure. be able to. In this case, for example, when the other outer locking piece is formed by bending the width determining main body into an L shape or a U shape, the width of the mold is first determined by the other outer locking piece. One mold can be locked, and then another mold can be locked by one outer locking piece. The width determination tool for the mold frame is stabilized (fixed) by locking the two mold frames by the outer locking pieces on both sides. When one mold is locked by the outer locking piece, the mold width determining tool can be in a free posture, and the mold can be locked. In addition, it is possible to use the said latching structure for the outer side latching piece of both sides.

  Further, the present invention relating to the width determining tool for the formwork is provided with an outer locking piece provided at both ends of the long width-stopping main body for regulating the position of the outer side of the moldwork, and the width stopper from the outer locking piece In the formwork width stopper provided at a position having a predetermined distance toward the longitudinal center of the main body, and including an inner locking piece that regulates the position inside the mold, at least one outer locking piece is A width-determining area that is erected so that a formwork contact surface portion is formed toward the inner locking piece while being continuous with the width-determining body, and a part of the width-determining area is cut out. There is an apparatus including a notch region and a locking member provided so as to be able to protrude and retract with respect to the surface of the mold contact surface portion through the notch region.

  Also in the above configuration, the locking structure is used for at least one outer locking piece of the formwork width determining tool, and the other outer locking piece can be a conventional type, and both outer locking The piece can also be a locking structure according to the present application. In this configuration, an inner locking piece that restricts the position inside the mold is configured, and the end of the mold is inserted between the inner locking piece and the outer locking piece. However, even in such a configuration, the locking structure of the present application can be used.

  In the invention relating to the above-mentioned width determining tool for formwork, the configuration and material of the locking member can be embodied as appropriate as in the invention related to the locking structure described above. That is, for example, the locking member includes a locking member main body whose base is supported by the width determining main body, and a locking projection provided at the tip thereof. A stop protrusion can be comprised so that it can protrude and project with respect to the surface of a form-frame contact surface part via a notch area | region. Further, the locking member main body can be configured to be biased so that the locking projection protrudes from the surface of the mold contact surface portion through the notch region. And you may make it comprise the whole or position of a locking member with a spring steel or a synthetic resin.

  Furthermore, in each of the above inventions, the width stop main body and the outer locking piece include both side rib pieces formed by bending both sides in the width direction to the back side, and the locking member main body is between the both side rib pieces. It can be set as the structure arrange | positioned.

  According to the above configuration, the width determining main body and the outer locking piece can increase the bending strength in the longitudinal direction by the configuration of the both-side rib pieces. At this time, the thickness of the width-determining main body and the outer locking piece also increases due to the presence of the rib pieces. Since the range near the center in the width direction of the outer side surface portion is in a hollow state, by arranging the locking member in the range (the hollow portion), the overall wall thickness including the locking member is It can be stored within the range of the state in which the piece is constructed.

  And in invention of the said structure, the base part of the said locking member main body can be set as the structure supported between the both-side rib pieces of this width stop main body in the back surface of the said width stop main part.

  According to the above configuration, since the locking member can be supported not by the outer locking piece but by the width determining body, it is not necessary to provide a support region for the locking member in the outer locking piece, and the outer engagement A stop piece can be comprised small. Thereby, the area | region which does not exhibit a direct effect | action in the width determination (or latching) of a formwork is not provided, but it can comprise by minimum required protrusion length from the width determination main body. Further, since the locking member main body can be disposed between the rib pieces on both sides, the locking member main body does not hinder the original action of the width determining main body and the outer locking piece.

  According to the present invention relating to the locking structure in the width determining tool for the formwork, the folding work is not required because the folding part is not used. For locking, the locking member can be projected from the formwork contact surface portion of the locking region. By forcing the locking member to move in the protruding direction, for example, by applying an urging force, the protruding member is in a normal state unless an external force is applied, so that the locked state is maintained. can do. Furthermore, by applying the urging force, an external force that resists the urging force is applied when the protrusion is temporarily released (the locking member is in a state in which the locking member is sunk) at the time of contact with the mold. This is possible. Therefore, it is possible to provide a locking structure that can easily perform the width determination operation and the removal operation of the formwork.

  Further, according to the present invention relating to the width determining tool for formwork, since the above-described locking structure is provided, the operation of locking and releasing by the outer locking piece having the locking structure is simplified. Can be made. That is, when the outer locking piece having the above-described locking structure is configured in one, the mold is locked first by the outer locking piece at the other end, and then the remaining mold is locked. Therefore, the width of the mold can be easily determined by the width determining tool for the mold. Further, if the above-described locking structure is provided on the outer locking pieces on both sides, the two molds can be easily locked.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a first embodiment of a locking structure in a formwork width determining tool. As shown in this figure, the present embodiment relates to a locking structure in the outer locking piece 2 formed at the distal end 11 of the long width determining body 1, and the outer locking piece 2 is A width determining region 3, a cutout region 4 formed by cutting out a part thereof, and a locking member 5 disposed in the vicinity of the cutout region 4 are provided.

  The width determining region 3 formed on the outer locking piece 2 is configured to be bent at an appropriate position near the end of the width determining main body 1 and is erected in a direction perpendicular to the surface 1 a of the width determining main body 1. It has become a state. The width determining region 3 is provided with a plane portion (formwork contact surface portion) 31 having an appropriate area toward the other end 12 of the width determination main body 1, and the formwork contact surface portion 31 should be locked. By contacting the outer surface of the mold, the width of the mold can be determined.

  Further, the cutout region 4 formed in the outer locking piece 2 is formed by cutting out a part of the width determining region 3. In the present embodiment, the width determining region 3 is rectangular, and is formed in an appropriate range that is symmetric in the width direction from the center of one side, and by appropriately cutting out the range in the height direction. Therefore, the mold contact surface portion 31 of the width determining region 3 is configured such that a U-shaped plane is formed in the vicinity of the boundary with the width determining main body 1 and on both sides of the cutout region 4.

  Therefore, the locking member 5 is provided with a locking protrusion 51 having a shape that can pass through the notch region 4, and the tip of the locking protrusion 51 is formed on the mold contact surface portion by utilizing the bending of the locking member 5. It is comprised so that it can protrude on the surface side of 31. That is, the locking member 5 is provided separately from the width determining main body 1, and a part of the locking member 5 is fixed on the back side of the width determining main body 1 to allow bending, and the locking member 5 is externally locked. In the state closest to the piece 2, the tip can be protruded from the cutout region 4. Accordingly, when the locking member 5 is separated from the outer locking piece 2 in accordance with the bending state, the tip of the locking projection 51 is submerged on the back side of the width determining region 3. The locking projection 51 does not protrude from the surface of the contact surface portion 31. That is, the locking member 5 (particularly, the locking protrusion 51) is provided so as to be able to protrude and retract with respect to the surface of the mold contact surface portion 31 through the cutout region 4.

  In addition, the bending of the locking member 5 can be allowed by being made of an elastically deformable material such as spring steel or synthetic resin. It is biased in a predetermined direction. By setting the urging direction to a direction in which the locking projection 51 protrudes from the mold contact surface portion 31, the locking projection 51 is maintained in the locked state. Then, it is possible to temporarily release the locked state by bending (elastically deforming) the locking member 5 against the bias.

  Here, the detail of the locking member 5 in this embodiment is demonstrated. FIG. 2 is an exploded view in which a portion constituting the outer locking piece 2 is enlarged. As shown in this figure, the width determining region 3 is configured by bending a part of the width determining main body 1 vertically, and a notch region 4 is formed by notching the tip. Ribs 1b and 1c bent on the back side are formed on both sides of the width determining body 1 in the width direction W, and similar rib pieces 3b and 3c are also formed in the width determining region 3 continuous thereto. Yes. Further, a rib 6 is also formed near the center of the width determining body 1 in the width direction W to increase the bending strength. The central rib 6 is provided in an appropriate range along the longitudinal direction L of the width determining main body 1, and the range is provided in a state where the range is extruded toward the back side. Further, the rib 6 is also continuous with the width determining region 3, and the rib 6 is provided so as to straddle both. A fixed region 61 for fixing the locking member 5 is formed on a part of the rib 6 formed on the width determining body 1. The to-be-fixed region 61 is provided with through holes 62 and 63 and a protruding piece 65 in which a U-shaped cut area 64 is bent downward, and is configured to allow fixing to the locking member 5. Has been.

  The locking member 5 includes the above-described locking protrusion 51 and a locking member main body 52 continuous thereto, and the locking member main body 52 is formed by bending the width determining body 1 and the width determining region 3. It is provided in an L shape so as to match. A locking projection 51 is integrally formed at one end (the tip in the height direction H). The other end (base end) 52 is formed with a fixing region 54 for fixing to the width determining main body 1. The fixing region 54 is provided with two rod-like protrusions 55, 56, one through hole 57, and one rectangular protrusion 58 adjacent to the through hole 57. The protrusions 55, 56, 58 provided in the fixing region 54 are fitted into the through holes 62, 63 and the U-shaped range 64 of the fixed region 61 provided in the width determining body 1, and are inserted into the through holes 57. The bent protrusion 65 can be inserted. By fitting them together, the fixing position of the locking member 5 with respect to the width determining body 1 is determined, and by further fixing both, the locking member 5 is attached to the width determining body 1 at the base 53. Will be supported.

  Further, the width dimension W5a of the locking projection 51 is slightly smaller than the width dimension W4 of the cutout region 4, and an appropriate range around the most bulging portion of the locking projection 51 is within the cutout region 4. (Through the notch region 4), the mold contact surface portion 31 can be protruded to the surface side. The width dimension W5b of the locking member main body 52 is larger than the width dimension W4 of the notch area 4 and smaller than the width dimension W3 of the width determining area 3, and ribs formed on both sides of the width determining area 3 Inside the pieces 3b and 3c, it can contact | abut to the back surface side of the formwork contact surface part 31. FIG. Therefore, the locking member main body 52 functions as a stopper when the locking projection 51 protrudes. Then, as described above, the locking member 5 having the base 53 supported by the width determining body 1 is elastically deformed with the base 53 as a fulcrum, thereby changing the position of the locking projection 51 (the mold contact surface portion 31). The relative positional relationship between the two and the other can be changed, and it is possible to make it appear and disappear.

  That is, as shown in FIG. 3, the locking protrusion 51 is fitted into the cutout region 4, and a part of the locking protrusion 51 can protrude from the surface side of the mold contact surface portion 31, and the locking member body 52 bends. By (elastically deforming), the locking projection 51 can be retracted to a state where it does not fit into the cutout region 4. The locking projection 51 bulges a portion that fits into the cutout region 4, and the bulging surface 51a gradually tapers toward the tip. And the surface (locking surface) 51b substantially parallel to the surface 1a of the width determination main body 1 is formed in the terminal of the bulging surface 51a. Therefore, by disposing the edge A1 of the mold A between the surface 1a of the width determining main body 1 and the locking surface 51b, the mold edge A1 can be locked. Further, since the bulging surface 51a is tapered, the width of the mold A is determined in the state where the locking member 5 is to be locked (the locking protrusion 51 protrudes from the mold contact surface portion 31). 1, when the bulging surface 51 a is in sliding contact with the mold edge A <b> 1, the locking projection 51 is guided in a direction away from the mold A and inevitably sunk from the notch region 4. It will be like that.

  For securing the locking member 5, when the material of the locking member 5 is a synthetic resin, the protrusions 55, 56, and 58 are fitted (inserted) into the through holes 62 and 63 and the U-shaped range 64. In this state, each tip can be melted to be welded. In addition to this, it is also possible to use an adhesive or the like. Furthermore, as shown in FIG. 3, the tips of the respective portions 55, 56, and 58 are bulged by plastic deformation so that they can be fixed while being prevented from being pulled out. Further, the locking member main body 52 has a portion 59 that is partially thinned or perforated. This is for relaxing the elastic force during elastic deformation. The elastic force (biasing force) can be adjusted by enlarging / reducing the range of the portion 59. Furthermore, the locking member main body 52 has a thickness equal to or less than the protruding length of the rib pieces 1 b and 1 c of the width determining body 1 and the rib pieces 3 b and 3 c of the width determining region 3, so Can be accommodated on the back side of the width determining body 1 and the width determining region 3 including the base 53.

  Further, as shown in FIGS. 1 and 3, the width determining body 1 is provided with an inner contact piece 7. The inner abutment piece 7 abuts on the inner surface A2 of the mold A and regulates its position. Therefore, as shown in the figure, a part of the width determining body 1 may be bent and configured to stand on the surface 1a. Alternatively, the entire width determining body 1 may be bent. . This modification will be described later.

  Next, a second embodiment according to the locking structure will be described. FIG. 4 is a diagram showing an outline of the present embodiment. As shown in this figure, the basic configuration is the same as that of the first embodiment, and in this embodiment, the detailed configuration of the locking member is different.

  That is, the outer locking piece 102 provided at the front end 111 of the width determining body 101 is also provided with a width determining region 103, and a notch region 104 is formed by notching a part thereof. The locking member 105 of the present embodiment has a locking projection 151, and is provided so that the locking projection 151 can protrude from the cutout region 104 to the formwork contact surface portion 131 of the width determining region 103. . The locking projection 151 is formed at the tip of the locking member main body 152, and the forming member 105 is formed as a whole. Therefore, the locking structure in the present embodiment has the same configuration as in the first embodiment.

  Accordingly, details of the locking member 105 of the present embodiment will be described. FIG. 5 is a diagram illustrating a processing procedure in which the locking member 105 is configured. As shown in this figure, the locking member 105 of the present embodiment is formed by bending a single metal material. The metal material only needs to be moderately elastically deformable, and spring steel can be used.

  As shown in FIG. 5A, the state before bending is formed into a predetermined shape by press working or the like. A one-dot chain line in the figure indicates a position to be bent. As shown in this figure, one plate-like member is roughly composed of a fixed region forming part 153 and a rising region forming part 154. Both are divided into a fixed region and a rising region by bending the folding position S1. Note that small cutout portions 155a and 155b are provided in a part of the rising region forming portion 154 to facilitate subsequent bending.

  The rising region forming portion 154 is further provided with locking surface forming portions 156a and 156b and locking protrusion forming portions 151a and 151b, which are bent along the bending positions S2, S3, S4 and S5 Each part is formed. The end surfaces 157a and 157b of the locking projection forming portions 151a and 151b are curved so that the end surface shape when the locking projection 151 is formed is tapered.

  Therefore, first, the locking surface forming portions 156a and 156 are bent along the bending positions S2 and S3 (see FIG. 5B). Thereby, the locking surface 156 is formed in the final completed state (FIG. 5D). Next, the locking protrusion forming portions 157a and 157b are bent along the bending positions S4 and S5 (see FIG. 5C). As a result, in the final completed state (FIG. 5D), the locking protrusion 151 having a tapered end surface is formed. Finally, it is bent along the boundary position S6 between the fixed region forming portion 153 and the rising region forming portion 154 (see FIG. 5D). Accordingly, the rising region constituting portion 154 constitutes the locking member main body 152, and the fixing region constituting portion 153 constitutes the base portion thereof. Then, by fixing this fixing region constituting portion (fixed region after bending) 153 to the width determining main body 101, it can be integrated with the width determining main body 101.

  In addition, a through hole 158 and a concave portion 159 are formed in the fixing region constituent portion (fixed region after bending) 153, and the through hole 158 projects a part of the width determining body 101 to the back side. The protruding piece 165 is allowed to be fitted, and the protruding piece 165 is further bent after fitting so that the protruding piece 165 can be fixed. The concave portion 159 is for avoiding the contact of the rib 106 when the rib 106 is provided on the width determining main body 101.

  In the present embodiment configured as described above, the edge of the formwork can be locked as in the first embodiment. That is, as shown in FIG. 6, the locking protrusion 151 can project to the surface side of the formwork contact surface portion 131 of the width determining region 103 through (inserting into) the cutout region 104. The locking protrusion 151 can be retracted by the elastic deformation of the locking member main body 152 exclusively. Further, the end edge 157b of the locking projection 151 has a tapered shape, and a locking surface portion 156b is formed on the end side so that the end A1 of the mold A can be locked. It is.

  Here, a modified example of the locking structure will be described. FIG. 7 is a diagram illustrating a modification. In the modification, instead of the inner locking piece 7 in the first embodiment (see FIG. 1), the width determining body 1 is bent. That is, at the position where the inner locking piece 7 is to be provided, the width determining body 1 is bent toward the surface 1a, and the central portion 10 is configured to have a height different from that of the surface 1a. By providing such a central portion 10, the contact surface 10 a (the contact surface 10 b on the other end side) can be formed on the tip side. By bringing the inner surface of the mold frame into contact with the contact surface 10a (, 10b), the mold frame can be fitted between the outer locking pieces 2 and 102 of the above embodiment.

  Next, a mold width determining tool using the above locking structure will be described. As already shown in FIGS. 1 and 4, the formwork width determining tool has a locking structure having the above-described configuration for at least one of the outer locking pieces provided at both ends 11, 12, 111, 112. The outer locking pieces 2 and 102 are used. FIGS. 1 and 4 show a structure in which both ends 11, 12, 111, 112 have the same locking structure.

  Then, the usage form is shown in FIG. 8 and FIG. 9 about the width determining tool for formwork provided with the first embodiment concerning the said locking structure at both ends. FIG. 8 shows a state where the width is determined at the lower ends of the two molds A, and FIG. 9 shows a state where the width is determined at the upper ends of the two molds A, B. By locking the molds A and B at the upper and lower ends, the width of the entire molds A and B is determined while maintaining a predetermined distance. The width will be decided.

  As shown in FIG. 8 (a), when determining the width of the lower ends of the molds A and B, the positions where the molds A and B should be installed with the main body surface 1a of the mold width determining tool facing upward. Placed on. For example, when configuring a fabric foundation, it is placed on the surface of the footing X. At this time, the longitudinal direction of the width determining body 1 is the direction in which the molds A and B face each other, and both ends 11 and 12 are adjusted to the positions where the molds A and B are to be installed. In this state, by lowering the molds A and B, the lower ends thereof are locked by both ends 11 and 12.

  That is, the lower end is inserted between the outer locking pieces 2A and 2B provided at both ends 11 and 12 of the width determining body 1 and the inner locking pieces 7A and 7B. At this time, since the outer locking pieces 2A and 2B have the above-described locking structure, a part of the lower end surfaces A3 and B3 is obtained by bringing the lower end surfaces A3 and B3 of the molds A and B closer to each other. However, it comes into contact with the locking projections 51A and 51B of the locking members 5A and 5B protruding from the mold contact surface portions 31A and 31B. By this contact, the locking projections 51A and 51B are pushed outward, and the locking members 5A and 5B are deformed, so that the locking projections 51A and 51B are submerged from the formwork contact surface portions 31A and 31B. It becomes.

  Between the outer locking pieces 2A and 2B with the locking protrusions 51A and 51B submerged, and the inner locking pieces 7A and 7B opposite to the outer locking pieces 2A and 2B, there is a gap that allows the molds A and B to be inserted. The lower end surfaces A3 and B3 of the molds A and B can be brought into contact with the surface 1a of the width determining body 1. At this time, the lower end external parts A1 and A2 of the molds A and B are in contact with the mold form contact surface portions 31A and 31B, and the lower end external parts A1 and A2 are lower than the locking projections 51A and 51B. This is because the protrusions 51A and 51B cannot be pushed outward.

  Therefore, as shown in FIG. 8 (b), the locking projections 51A and 51B are restored by the elastic force of the locking members 5A and 5B, and the locking projections 51A and 51B protrude from the mold contact surface portions 31A and 31B. Will be locked. In this state, the molds A and B are restricted from moving upward, and the positions of the inner surfaces A2 and B2 are restricted by the inner locking pieces 7A and 7B. The distance between A and B is determined (the width is determined).

  When the widths are determined at the upper ends of the molds A and B, as shown in FIG. 9A, the width for the mold is determined with respect to the upper ends of the molds A and B whose widths have already been determined. It is locked by both ends 11 and 12 of the tool. At this time, the mold width determining tool has the surface 1a of the width determining main body 1 facing downward, and the mold frames A, B between the outer locking pieces 2A, 2B and the inner locking pieces 7A, 7B at both ends 11,12. The upper end of B is invaded. Since the lower ends of the molds A and B are already fixed, the intrusion at this time is performed exclusively by lowering the mold width determining tool.

  That is, while the longitudinal direction of the width determining main body 1 is directed in the interval direction (width direction) of the molds A and B, the inner locking pieces 7A and 7B are placed on the inner surfaces A2 and B2 of the opposing molds A and B, respectively. Between the inner locking pieces 7A and 7B and the outer locking pieces 2A and 2B, the end portions of the mold frames A and B are mounted so that 7B abuts. At this time, as in the case of determining the width of the lower ends of the molds A and B, the locking projections 51A and 51B provided on the outer locking pieces 2A and 2B are pushed out by the upper end surfaces A5 and B5, It will be in the state sunk from contact surface part 31A, 31B. Further, when the upper end surfaces A5 and B5 come into contact with the surface 1a of the width determining main body 1, the upper end outer portions A4 and B4 of the molds A and B are positioned higher than the locking projections 51A and 51B, and the locking projection 51A , 51B protrudes again to the mold contact surface portions 31A, 31B, and locks the outer top ends A4, B4 (see FIG. 9B). Thus, by simultaneously locking the upper ends of the molds A and B, the width determination at the upper ends of the molds A and B is completed.

  When the upper and lower ends of the molds A and B are locked, as described above, the both ends 11 and 12 of the width determining body 1 are simultaneously approached and locked simultaneously with the two molds A and B. It is also possible to lock one mold (for example, A) first, and then lock the other mold (for example, B). For example, one side of the mold sizing tool is locked at an appropriate interval to the lower end of one mold A, and the mold is placed on the surface of the footing X or the like. The lower end of the formwork B can be locked. Even when the upper ends of the molds A and B are locked, the distance between the upper ends of the molds A and B is ignored, and one of the mold width determining tools is simply attached to one mold A at a predetermined interval. Then, the upper end of the other mold B can be locked using the non-locked side while adjusting the distance between the two molds A and B.

  In any of the above methods, the locking projections 51A and 51B are brought into contact with the end surfaces A3, B3, A5 and B5 in the locking operation with the molds A and B, so When the end faces A3, B3, A5, and B5 reach the surface of the width determining main body 1, the locking projections 51A and 51B are moved to the mold contact surface portions 31A and 31B. Therefore, the width determining operation can be completed very easily.

  In addition to the above-described configuration, the embodiment relating to the mold width determining tool may have the above-described locking structure only on one side. FIG. 10 is a diagram illustrating an example thereof. As shown in this figure, one end 11 is provided with outer locking pieces 2 and 102 (the figure shows the second embodiment 102) having the locking structure as described above, but the other end. The 12 outer locking pieces 202 are not provided with the locking members as described above. That is, the outer locking piece 202 is formed by simply bending the locking piece main body 221 inward and forming a protruding portion 222 that protrudes in a fixed manner. Even in such a configuration, if the two molds are not locked at the same time, that is, one mold is locked at the other end 12 having one outer locking piece 202, and then the one end 11 If the remaining mold is locked, the width of the mold can be determined. In this case, if the one end 11 to be locked later can be easily locked as described above, the entire locking operation can be performed quickly. That is, one lock can be locked without being aware of the interval between the two molds, and the interval between the molds can be adjusted when locking the remaining molds. If locking is easy, the width determining operation can be easily performed. This is remarkable when the width is determined at the upper end of the mold.

  FIG. 11 shows an example in which the above example is further modified. The modification shown in this figure is configured such that the width dimension of the surface 301 a of the width determining body 301 is different in the vicinity of both ends 311, 312 and in the vicinity of the center 313. That is, the width dimension in the vicinity of the center 313 is smaller than that in the vicinity of both ends 311 and 312. Even in such a configuration, the outer locking piece 302 and the inner locking piece 307 as in the vicinity of both ends 311 and 312 are not formed in the vicinity of the center 313, so that there is no problem in strength. It is. In this modified example, flat portions 314 and 315 are provided at both side edges in the width direction W. The flat portions 314 and 315 do not directly affect the locking of the mold, but when the lower end of the mold is locked, the outer locking pieces 302 and the inner locking pieces 307 are installed upward. At this time, it is possible to secure a contact surface with the surface of the lower structure (in the case of a cloth foundation construction formwork, see FIG. 8, such as footing X). By forming such a contact surface, even when a heavy-weight formwork is placed on the width determining body 301, the surface of the structure (such as the footing X) is prevented from being damaged. Will get.

  Further, in this modified example, the outer locking piece 302 at the other end 321 is simply formed by bending the locking piece main body 321 inward and projecting a fixed protrusion 322. In the vicinity of 321, the rib 306 provided in the center in the width direction is provided in a relatively deep state. Therefore, the protruding portion 322 is formed by bending the portion formed as the rib 306 in the opposite direction (to one end 311 of the width determining main body 301). In such a configuration, the protruding portion 322 is formed at the same time as the rib 306 is formed at the molding step, and the outer locking piece 302 is finally bent by bending the area where the outer locking piece 302 is finally formed. It can be installed, and the processing becomes easy.

  The embodiments of the present invention are as described above, but the present invention is not limited to these embodiments. Therefore, various forms can be made within the scope of the gist of the present invention. For example, in the embodiment related to the locking structure, the locking protrusions 51 and 151 provided on the locking members 5 and 105 have been described as being configured to appear and disappear on the surfaces of the mold contact surface portions 31 and 131. If the stop protrusions 51 and 151 are not distinguished from the lock member main bodies 52 and 152 and a part of the lock members 5 and 105 can protrude and appear on the surface of the mold contact surface portions 31 and 131, the object of the present invention is achieved. It can be achieved. In the first embodiment, the locking member 5 is made of synthetic resin, and the locking protrusion 51 and the locking member main body 52 are integrally formed. In the second embodiment, the metal material is bent. However, the engaging member main body 52 may be made of a metal material, the engaging protrusion 51 may be made of a synthetic resin, and both of them may be integrally fixed.

  Further, the cutout regions 4 and 104 are configured to be cut out so as to be rectangular in the center in the width direction at the front ends of the width determining regions 3 and 103, and the regions are opened at the front ends of the width determining regions 3 and 103. Although only the thing was demonstrated, this notch area | region 4,104 should just be a thing which a part (locking protrusion 51,151 etc.) of the locking members 5 and 105 can pass, and can also be comprised by a large hole. Moreover, even if it is the open notch area | region 4104, you may comprise it notching in shapes other than a rectangle.

  Further, the configuration of the width determining main body 1 uses a plate-like member almost as it is, but it is possible to use one that is largely bent as shown in FIG. The presence or absence of the configured rib pieces 1b and 1c or other rib structures can be selected as appropriate. And according to the structure of such a width determination main body 1, the structure of the inner side latching piece 7 can be changed suitably. Furthermore, as shown in FIG. 1 and FIG. 4, the width determining main bodies 1 and 101 may be provided with through holes at appropriate intervals. By providing such a through-hole, for example, when the formwork width determining tool is installed on the surface of a footing or the like, it becomes possible to insert a nail or the like into the through-hole and fix it.
