Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a separator with a marking projection for a formwork, and more particularly, to a separator with a marking projection which can be disposed on the surface of a formwork panel with extremely low labor.

[0002]

[Prior art]

 Conventionally, in formwork assembly, the positioning of separators (including "P-con" and "resin-con") to be disposed between the form panels in order to maintain an interval between the panels uses a measure or the like. It is common to do. However, measuring the placement position of the separator with a measure or the like for each form panel used many times not only does not improve the work efficiency, but also incorrectly measures the placement of the separator. There are many things.

[0005] Accordingly, in actual mold assembly, the following simple positioning method is adopted depending on the situation. That is, another form panel is superposed from the outside on the form panel in which the separator is arranged in the correct position in advance, and then a shock is applied with a hammer or the like to project to a predetermined position on the outer surface of the first form panel. At the end of each separator, scratch the surface of the other formwork panel. In this manner, the separator placement position was marked on the surface of the other formwork panel with an accurate placement of the separator (see FIG. 1).

However, since the conventional separator has a flat shaft end surface, a considerable impact must be applied with a hammer or the like to damage the surface of another form panel at the end of the separator. There was an inconvenience that the formwork panels that were accurately superimposed when hit with a hammer were misaligned, and that the advantage of this simple marking operation could not be fully exploited.

[0005]

[Problems to be solved by the invention]

 The present invention has been made in view of the above-described inconvenience of the conventional mold separator, and a marking that can extremely efficiently save the positioning of the separator on the form panel surface. A technical problem is to provide a separator with projections.

[0006]

[Means for Solving the Problems]

 According to the present invention, in order to solve the above-mentioned technical problem, a technique is provided in which at least one end 11 of the mold separator 1 is provided with a marking projection 12 which easily damages the surface of the mold panel 3 '. Tactics were adopted.

In order to solve the above-mentioned technical problem, the present invention provides a form panel, which is provided at at least one end of a form separator 1 at an end of a shaft leg 21 of a cone member 20. The technical means of forming marking projections 22 which easily damage the surface of 3 'was adopted.

[0008] Furthermore, the present invention, in order to solve the above-mentioned problem, adds to the above-mentioned problem as necessary. In addition, the marking projections (12, 22) which can easily damage the form panel 3 'are provided on the separator 1 or the cone member 20. The technical means that the end face center portion 13 at the end of the shaft leg 21 is formed in a concave circumferential projection shape is employed.

[0009]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings. FIG. 1 is a partially omitted cross-sectional view showing a marking operation by a separator with a marking projection (cup separator) of the present embodiment, and FIG. 2 is a sectional view of a marking projection of a separator with a marking projection (cup separator) of the embodiment. FIG. 3 is an enlarged cross-sectional view, and FIG. 3 is a partially omitted cross-sectional view showing a modified example (P-con) of the separator with a marking protrusion according to the present invention.

In the drawing, the one designated by reference numeral 1 is previously disposed at a predetermined position between the pair of plywood form panels 3, 3 in order to keep the pair of opposed plywood form panels 3, 3 at a predetermined interval. It is a separator. The separator 1 of the present embodiment is provided with a pair of left and right hemispherical synthetic resin cups 10 that are in contact with the inner surfaces of the form panels 3 and 3, and is configured as a so-called cup separator.

As shown in the cross-sectional view of FIG. 2, the end portions 11 of the separator 1 have a central portion 13 at the end surface thereof and a marking protrusion 12 having a circumferential protrusion shape formed around the end surface. ing. The marking projection 12 damages a predetermined position on the surface of another form panel 3 ', so that the arrangement position of another separator can be accurately determined.

That is, as shown in FIGS. 1 and 2, another form panel 3 ′ is superimposed from outside on a form panel 3 on which a separator 1 is previously arranged at an accurate position by measuring. Then, by simply tapping the form panel 3 'from the outside with a hammer H in the superimposed state, the marking protrusions 12 of the separator 1 scratch the predetermined position on the surface of the form panel 3', The exact separator position of the formwork panel 3 is marked so as to be copied on the surface of the other formwork panel 3 ', and the arrangement of other separators to be arranged on this other formwork panel 3'. The installation position can be easily determined.

As described above, in the separator 1 of the present embodiment, since the marking projections 12 are formed at the end portions 11 thereof, the force is significantly smaller than that of a conventional separator having a flat end surface. Can damage the surface of the other formwork panel 3 ', making it possible to perform the work of positioning the separator extremely labor-saving, and to further improve the efficiency, accuracy and safety of the formwork assembly work. You can.

In addition, in the separator 1 of the present embodiment, the marking projections 12 are formed in a circumferential projection shape in which the center 13 of the end face is concave, so that there is no fear that the marking projections 12 may damage an operator. Thus, the formwork can be safely assembled.

An embodiment which is a specific example of the present invention is generally configured as described above. However, the present invention is not limited to this embodiment, and is described in “Claims for Registering Utility Model”. Various modifications are possible. For example, in the above-described embodiment, the present invention is described by taking as an example a cup separator in which cups 10 are provided on both sides of the shaft.However, the present invention is not limited to this, and a separator having hexagonal seats on both sides of the shaft is provided. It is also possible to form a marking projection on the end of the device.

As shown in FIG. 3, the end of the shaft leg 21 of a cone member 20 (commonly called “P-con”; plastic cone) made of synthetic resin having a truncated cone shape to be provided at the end of the separator 1 is provided. It is also possible to form a similar marking protrusion 22.

Further, the shape of the marking projections (12, 22) that damage the form panel 3 'is not limited to the above-described embodiment, and the cross-shaped projections on the end face of the shaft leg 21 of the separator 1 or the cone member 20 may be used. Various design changes are possible according to the type and thickness of the formwork panel to be marked.

[0018]

[Effect of the invention]

 As described above in the embodiment, in the present invention, a marking protrusion is formed on the shaft end of the separator or on the shaft leg end of the cone member to be provided at the shaft end of the separator. As a result, the surface of other formwork panels can be scratched with much less force compared to conventional products with flat end faces, making it possible to perform separator positioning work very labor-saving. The efficiency, accuracy and safety of the frame assembling work can be further improved.

Further, if the marking projections are formed in a circumferential projection shape as required, there is no fear that the marking projections may damage an operator, and the formwork assembling operation can be performed safely.
