Abstract

(57) [Summary] [Purpose] A separator for concrete panels is used to form concrete formwork using corrugated metal sheets. [Structure] A plate body having a spring property having a width corresponding to a difference from the thickness of a concrete panel is folded back from an approximate center to form a folded-back portion 2 so that both ends are brought close to each other, and the approached opposites are made. The attachment 1 is formed by bending an arc-shaped grip portion 3 that sandwiches the outer periphery of the separator on the surface and a separator introduction portion 4 that is continuous with the grip portion 3 and has both tip portions expanded to both sides.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an attachment for a thin plate of a separator, which can divert a separator for a concrete panel to a metal corrugated thin plate when forming a concrete formwork with the metal corrugated thin plate.

[0002]

[Prior art]

Generally, as a material for forming concrete formwork, a thick plywood board called a concrete panel is used, but since it is heavy and bulky and has poor durability, an attempt to use a metal corrugated thin board has been made. . However, commercially available separators are designed to fit concrete panels, and therefore cannot be used as they are for metal corrugated thin plates having different thicknesses. Not only is it expensive to create a dedicated type, but also two types of separators with different standards coexist, causing confusion among consumers. Therefore, conventionally, a piece of wood or a plastic piece provided with a separator insertion hole is inserted into the separator insertion hole, or is hammered between the flange portion of the home tie (registered trademark) and the surface of the thin plate. As a result, it was designed to intervene between the flange and the surface of the thin plate to compensate for the length corresponding to the difference in thickness.

[0003]

[Problems to be solved by the device]

 In the past, since it was just a make-up, the separator must be inserted through the separator insertion hole, making it difficult to attach and detach, and when wedge-shaped it is easy to fall off or damage. In order to popularize metal corrugated thin plates for forming concrete formwork, it has been desired to develop an attachment that can be securely mounted and is easily removable.

[0004]

[Means for Solving the Problems]

 The present invention provides a highly lightweight attachment that can be attached to and detached from the separator with one touch, and has excellent operability. The configuration of the attachment has a width corresponding to the difference in thickness between the concrete panel and the corrugated metal thin plate. The flexible plate is folded back from the approximate center into an arbitrary shape so that both ends are close to each other, and the arc-shaped gripping part that sandwiches the outer periphery of the separator between the facing facing surfaces is continuous with the gripping part. A separator introduction part is formed by expanding both tip parts to both sides, and a notch is made in a block made of synthetic resin in a direction perpendicular to the thickness direction, and the attachment for the thin plate is provided on the inner surface of the notch. The holding part and the introduction part of the above are formed.

[0005]

[Action]

 It can be attached to the separator simply by pressing the introduction part to the side surface of the separator, and the attachment holding the separator is securely attached by the spring force. When pulling it off, simply pull it to remove it easily. It can also be used repeatedly and is economical.

【Example】

 An attachment according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the attachment 1. The attachment 1 has a spring property of a metal having a width corresponding to the difference between the thickness of a concrete panel (not shown) and a metal corrugated thin plate 5 described later. The center of the plate is folded back into an inverted triangle to form the folded-back portion 2, both ends are brought close to each other, and the arc-shaped gripping portion 3.3 that sandwiches the outer circumference of the separator between the facing opposing surfaces and the gripping portion 3 are provided. A separator introducing portion 4 in which both tip portions are continuously expanded on both sides is formed by bending.

FIG. 3 shows a buried type concrete formwork using the corrugated metal thin plate 5, so that it is possible to remove the foundation (which is abandoned concrete at the site) from the depression dug in the ground or the bottom of the cut slope. 6), and a frame receiving runner 7 is laid on the base 6. The metal corrugated thin plates 5 are continuously arranged so that their lower edges are sandwiched by the frame receiving runners 7 and the adjacent metal corrugated thin plates 5.5 are partially overlapped with each other. The corners are connected by corner fittings 8, and the height adjustment cap 9 is attached to the upper edge. The metal corrugated thin plate 5 has a separator insertion hole 10.10 ... And a small hole 11.11 .. The separators 12 are installed between the metal corrugated thin plates 5.5 that face each other, and both ends of the separators 12 project from the separator insertion holes 10.

The attachment 1 is laterally pressed and fitted to the root of a commercially available separator 12 protruding from the separator insertion hole 10 of the assembled frame, and the home tie 13 is connected to the home tie. It is interposed between the flange portion 14 of 13 and the plate surface of the metallic corrugated thin plate 5 (FIG. 2). Since the attachment 1 is attached from the side of the separator 12, the home tie 13 can be connected first when the attachment 1 is attached.

With the interposition of the attachment 1, the commercially available separator 7 can be securely attached to the metal corrugated thin plate 5 without rattling, and the separator for concrete panel is used as if it is a separator exclusively for thin plates. it can. The attachment made of a metal plate has a high compressive strength against lateral pressure, though it is lightweight because the load acts in a direction perpendicular to the plate surface.

In the attachment of the present embodiment, it is considered that the folded-back portion has an inverted triangle shape so as to increase the contact surface with the flange portion. However, the attachment has a more complicated shape to increase the contact portion with the flange portion. However, the pressure resistance can be increased. Further, the material may be a synthetic resin other than the metal thin plate. In this case, for example, as shown in FIG. 4, a disc-shaped block is provided with a cut 15 in a direction perpendicular to the thickness direction, and the cut 15 A synthetic resin can be formed by forming on the inner surface a grip portion 3 consisting of a partially cutout hole corresponding to an arc-shaped grip portion formed on the metal thin plate attachment 1 and a separator introducing portion 4.4. The unique spring property is utilized to exert a gripping function comparable to that of the metal thin plate attachment. Even in the case of synthetic resin, the outer circumference can be formed in any shape, and a knob portion may be provided or the outer circumference may be asymmetrical. Further, the concrete formwork of the practical example is a buried type, but it can also be used for a type that is demolished after the concrete is solidified.

[0011]

[Effect of device]

 According to the present invention, a separator for a concrete panel can be used for forming a concrete formwork using a corrugated metal thin plate. In particular, it is lightweight, highly reliable, and can be used over and over again.
