Description

  In the present invention, for example, in the case of constructing a concrete underground wall using a sheet pile for earth retaining, or in the construction of a steel-framed reinforced concrete structure using H-shaped steel, a plate-like portion made of such steel is used. The present invention relates to a member attaching tool for a plate-like portion suitable for attaching a mold frame while maintaining a predetermined interval or attaching another appropriate member. In particular, the present invention relates to an improvement in a member mounting tool for a plate-like portion that is highly adaptable to plate-like portions having different thicknesses and is extremely easy to use.

With regard to a member mounting tool using this type of plate-shaped portion, a U-shaped sandwiching portion that can be fitted to a plate-shaped portion made of a shape steel or the like is provided at one end of a pipe-shaped intermediate member. A member mounting tool having a female thread portion for mounting a member at the other end is known (see cited document 1). However, in the case of this prior art, the adaptability of the sandwiched portion made of a U-shape is small, and when the plate-shaped portion is thin, play occurs between the sandwiched portion and when it is thick, There is a technical drawback that not only the mouth portion is greatly expanded and the sandwiched state becomes unstable, but the intermediate member is easily inclined. Therefore, in order to improve the adaptability to the thickness of the plate-like portion, a plate spring is used as one of the sandwich pieces and a substantially U-shaped sandwich portion is configured (see Reference 2), One in which an inclined cut-and-raised portion is formed on a sandwich piece (see cited document 3) is known. However, even in the case of these prior arts, although the adaptability to the thickness of the plate-like portion can be improved, the manufacturing cost is increased due to the complicated configuration due to the adoption of the leaf spring and the inclined cut-and-raised portion. There were technical shortcomings.

  The present invention has been developed in view of the above-described conventional technical situation, and has a simpler structure, which has good adaptability to the thickness of the plate-like portion, and provides a strong and stable clamping state. Therefore, it is effective to reduce the manufacturing cost, and an object of the present invention is to provide a member mounting tool for a plate-shaped part that is very easy to use.

In order to solve the above-mentioned problem, in the invention of claim 1, the intermediate member is provided with a substantially U-shaped sandwiching portion that can be fitted to a plate-like portion made of a shape steel or the like at one end portion of the intermediate member, and the other end. In a member mounting tool for mounting a member as appropriate to a plate-shaped portion, the member having a female screw portion for mounting the member, clamping one clamping piece constituting the substantially U-shaped clamping portion The surface is formed so that at least a part of the surface can come into contact with the plate-like portion in a planar manner, and the sandwiching surface of the other sandwiching piece is on the sandwiching side from the center portion on both sides of the sandwiching surface. The gap between the opposing sandwiching pieces is formed so that both sides are gradually narrower than the center part, and the sandwiching part is fitted to the plate-like part. When wearing, the contact with the plate-like portion starts from both sides of the other sandwich piece, and the plate according to the thickness of the plate-like portion Abutting portion vicinity of the part is deformed to partially outwardly, and configured to be able to adapt to changes in the thickness of the plate-like portion. Clamping face of the other clipping piece constituting the clamping part, to a part or the entire length of its may be formed in a curved surface (claim 2), symmetrical inclined surfaces bordering the central portion It is also possible to form it. Further, the other sandwiching piece constituting the sandwiching portion is formed in a state in which the tip end side, that is, the free end side, protrudes from the connecting side connecting the sandwiching pieces on both sides toward the sandwiching side in the cross-sectional shape. In addition, it may be configured to abut on the plate-like portion on the distal end side of the sandwiching piece.

According to the present invention, as described above, the sandwiching surface of one sandwiching piece constituting the substantially U-shaped sandwiching portion is set so that both sides on the sandwiching surface are directed toward the sandwiching side from the center portion. formed to gradually protrude, by an extremely simple configuration that the spacing between opposing clamping strips mutually configured to both sides gradually narrower than the central portion, adapted to changes in the thickness of the plate-like portion can do. Therefore, it is possible to reduce the manufacturing cost by simplifying the configuration, and the plate-like portion of the sandwiching piece formed so as to gradually protrude toward the sandwiching side according to the thickness thereof . Since it is clamped in a state of being smoothly and accurately pressed at the abutting portions with the clamping surfaces on both sides , a strong and stable clamping state can be easily obtained without causing play. In addition, when the thickness of the plate-like portion changes, the portion in the vicinity of the contact portion with the plate-like portion of the sandwiching piece is partially deformed outward according to the thickness, thereby the plate-like portion. Since most of the change in thickness of the part is absorbed, the degree of expansion between the sandwiched pieces is reduced compared to the prior art, and the influence on the installation state of the intermediate member fixed to the sandwiched part is also reduced. Reduced.

The member mounting tool according to the present invention can be widely applied to a case where a formwork is mounted with a predetermined interval using a plate-shaped portion made of a shape steel or the like, or when another appropriate member is mounted. . The intermediate member may be a pipe, a solid shaft, or a plate. In short, if it is possible to equip one end with a substantially U-shaped clamping part and the other end to have a female thread part for attaching a member, its length and specific Any desired shape can be selected. Further, the intermediate member and the substantially U-shaped sandwiching portion may be formed integrally, or may be formed by fixing each separately formed member to welding or the like. Regarding the female screw portion, a female screw may be formed directly at the end of the intermediate member itself, or a female screw member formed separately may be welded later. As described above, at least a part of the sandwiching surface of one sandwiching piece constituting the substantially U-shaped sandwiching portion abuts the plate-like portion in a planar manner so that the plate-like portion is stably provided. Configured to support. Further, the other sandwiching piece is formed such that the sandwiching surface gradually protrudes toward the sandwiching side toward the both sides from the center part on the sandwiching surface, so that the opposing sandwiching pieces are between each other. The interval is configured to gradually narrow toward the both sides from the central portion. For example, the substantially U-shaped sandwiching portion is formed by first bending a flat plate material to form a U-shaped sandwiching portion in which the corresponding sandwiching pieces on both sides are parallel, and further sandwiching one of the sandwiched portions. It can be easily manufactured by bending both sides of the clamping surface of the piece inward. In this case, the largest projecting portion with the largest projecting amount projecting toward the sandwiching side may be set at the outermost end portions on both sides on the sandwiching surface of the sandwiching piece, You may set to the position which entered inside from the outermost edge part. Further, as described above, the surface connecting the maximum projecting portion and the central portion may be partly or entirely curved and may be formed on a symmetrical inclined surface with the central portion as a boundary. . Furthermore, the cross-sectional shape of the sandwiching piece is formed in a state in which the tip end side protrudes from the connecting side connecting the sandwiching pieces on both sides toward the sandwiching side, and a plate shape is formed on the tip end side of the sandwiching piece. You may comprise so that it may contact | abut. In short, when the plate-like portion is inserted between the opposing sandwiching pieces constituting the substantially U-shaped sandwiching portion, the contact with the plate-like portion starts from both sides of one sandwiching piece. The thickness of the plate-like portion is determined by partially deforming the vicinity of the contact portion with the plate-like portion outward depending on the thickness of the plate-like portion, and crimping the plate-like portion by the deformation restoring force. Anything that can adapt to the change in height is acceptable. By the way, depending on the thickness of the plate-like part, the contact part vicinity part of the sandwich piece and the plate-like part is partially deformed to the outside, so that the contact part gradually moves toward the central part. Including.

FIG. 3 and FIG. 3 are views as seen from the direction of arrow A as seen from the direction A shown in FIG. As shown in the figure, the member mounting tool 1 for the plate-like portion according to the present embodiment is a pipe-like intermediate member 2 and a substantially U-shaped sandwiching member fixed to one end of the intermediate member 2 by welding. The part 3 and the female screw part 4 for attaching a member formed at the other end part are configured as main elements. In this embodiment, when the intermediate member 2 is fixed to the sandwiching portion 3, it is slightly tilted in the reverse direction in advance in order to absorb the tilt accompanying the fitting of the sandwiching portion 3 to the plate-like portion. It is stuck to the state. Incidentally, regarding the inclination of the intermediate member 2, in the case of the prior art, since the amount of inclination accompanying the fitting to the plate-like portion varies greatly depending on the thickness of the plate-like portion, it is difficult to respond accurately. However, in the case of the present invention, the degree of inclination accompanying the fitting to the plate-like portion is reduced, and a relatively small correction amount is sufficient, so that it can be handled easily and accurately. In the figure, reference numeral 5 denotes a support member for the attachment member fixed to the end of the intermediate member 2, and a male screw insertion hole 7 corresponding to the female screw portion 4 is formed in the abutting plate portion 6. Therefore, when the member mounting tool 1 is used and the plate-shaped portion 8 is used to mount, for example, a mold with a predetermined amount apart, the substantially U-shaped sandwiching portion 3 is fitted to the target plate-shaped portion 8. After being attached, the inner surface of the mold is brought into contact with and supported by the abutting plate portion 6 of the support member 5, and a male screw (not shown) is screwed into the female screw portion 4 through the insertion hole 7 and tightened. Thus, the mold can be easily installed at a predetermined position. Further, conversely, after the inner surface of the mold frame is brought into contact with the abutting plate portion 6 of the support member 5 and the mold frame is fixed to the member mounting tool 1 side, the substantially U-shaped sandwiching portion 3 is formed as a target. A procedure of fitting to the plate-like portion 8 is also possible.

  Next, features of the present invention will be described. As shown in FIGS. 2 and 3, the sandwiching portion 3 of the member mounting tool 1 according to the present embodiment is formed so that the sandwiching surface can abut against the plate-like portion 8 in a plane. The sandwiching piece 9, the other sandwiching piece 10 facing the sandwiching piece 9, and the connecting side 11 connecting these sandwiching pieces 9, 10 are formed in a substantially U-shape. As shown in FIG. 3, one sandwiching piece 9 in the present embodiment is formed so that the connecting side 11 side is flat so that the plate-like portion 8 can abut on the plane. Further, the other sandwiching piece 10 adopts a curved surface in part so that both sides 12 and 13 of the sandwiching surface gradually protrude from the central portion 14 toward the sandwiching side, and the opposing sandwiching piece 9 , 10 is configured such that the sides 12 and 13 are narrower than the central portion 14. Incidentally, the substantially U-shaped sandwiching portion 3 is formed, for example, as described above by first bending a plate-shaped material to form a U-shaped sandwiching portion in which corresponding sandwiching pieces on both sides are parallel, It can be easily manufactured by bending both sides 12 and 13 of the sandwiching surface of the one sandwiching piece 10 inward. As shown in the enlarged sectional view of FIG. 2, the other sandwich piece 10 in the present embodiment has a tip end side (a free end side below in FIG. 2) sandwiched from the connection side 11 side in the sectional shape. It is formed in a state protruding toward the wearing side. In particular, as shown in the figure, the portion slightly inward from the tip is the largest projecting portion 15 having the largest projecting amount, and forms a region having the narrowest distance from the sandwiching piece 9 on the cross-sectional shape. Yes. Incidentally, in the case of the present embodiment, about half of the connecting side 11 side forms a region where the interval between the sandwiching pieces 9 and 10 is wide. In addition, as shown in FIG. 2, you may form the inclination guide part 16 extended outside on the front-end | tip part side of the clamping piece 9 as needed. It is also possible to change the inclination angle and the installation length of the inclination guide portion 16.

  Therefore, when the clamping part 3 of the member mounting tool 1 is fitted to the target plate-like part 8, the part with the smallest distance between the clamping pieces 9, 10 is shown in FIG. The contact starts from the portions 12 and 13 on both sides of the sandwiching surface of the sandwiching piece 10 and the portion of the maximum protrusion 15 on the cross section shown in FIG. And when the thickness of the said plate-shaped part 8 is thicker than the said minimum space | interval between the clamping pieces 9 and 10, when the clamping part 3 is pushed in with respect to the plate-shaped part 8, the plate-shaped part 8 and The portions 12 and 13 on both sides of the sandwiching piece 10 that is in contact are deformed outward. As a result, the contact portion between the plate-like portion 8 and the sandwiching piece 10 gradually moves toward the central portion 14 side where the spacing between the sandwiching pieces 9 and 10 is wide, By the deformation restoring force of 13 portions, the plate-like portion 8 is sandwiched at an interval corresponding to the thickness. As described above, in the case of the member mounting tool 1 according to the present invention, the portion near the abutting portion on the side of the sandwiching piece 10 is partially deformed outwardly, so Is configured to adapt to the thickness of the plate-like portion 8, so that the sandwiching pieces 9, 10 can be connected to each other when the sandwiching portion 3 is fitted to the plate-like portion 8 with a very simple structure. The degree of expansion can be greatly reduced. Therefore, the planar contact state between the sandwiching piece 9 and the plate-like portion 8 is stably maintained, and a strong and stable sandwiching state can be obtained accurately without causing play. In addition, since the degree of inclination of the sandwiching piece 10 accompanying the fitting of the sandwiching part 3 to the plate-like part 8 is also reduced, the amount of inclination of the intermediate member 2 that is inclined in the reverse direction for its absorption. Therefore, it is possible to provide a member mounting tool for a plate-shaped part that is easy to use. Incidentally, in the case of the present embodiment, the gap between the sandwiching pieces 9 and 10 on the connecting side 11 side shown in FIG. 2 is the widest at the position of the central portion 14 of the sandwiching piece 10 shown in FIG. In the region, the applicable thickness of the plate-like portion 8 is restricted.

It is the whole block diagram which showed the Example of this invention. It is the expanded sectional view which showed the clamping part in the Example. FIG. 3 is a view taken in the direction of arrow A as viewed from the A direction shown in FIG. 2.
