Description

[Detailed Description of the Invention] Technical Field This invention relates to a spacing holder for maintaining the spacing between concrete forms when pouring foundation concrete for a building.

Prior Art Conventionally, in a concrete form spacing holder 10 formed by bending both ends of a strip-shaped board upward as shown in FIG. 4, each spacing holder is aligned and It is necessary to accurately count the quantity while packing, and this packing process is extremely troublesome and increases labor costs.It also has the disadvantage that it is easy to cause excess or deficiency in quantity due to human error or mechanical error caused by automatic quantity meters, etc. Ta.

The object of this invention is to provide a spacer having a structure which simplifies the packaging work for the spacer as described above, reduces the cost required for packaging, and prevents excess or deficiency in the quantity when packaged.

Embodiment Hereinafter, an embodiment embodying this invention will be described with reference to FIGS. This is a concrete formwork spacing holder having protruding reinforcing ribs 4, in which a notch provided at the same position is bent upward at a position at a distance corresponding to the thickness of the concrete formwork from the outer regulating piece 2. An inner regulating piece 3 is provided.

As shown in FIG. 1, the spacer 1 constructed as described above is connected to 10 wires in the lateral direction by uncut portions 5 as connecting portions provided at two locations on both side edges or one side edge. By connecting them, the spacer retainer connected body of this invention is constructed. A sufficiently visible gap C (in this embodiment, the dimension is approximately the same as the thickness of the iron plate) is formed between each spacing holder 1 over the entire longitudinal direction excluding the uncut portion 5. .

Next, the manufacturing procedure of a connected body of 10 spacer retainers will be explained with reference to FIG. 2.

First, cuts A are made in a sheet of iron plate at intervals corresponding to the width of the spacer 1 using a press machine, leaving the uncut portions 5, and at the same time, the inner regulating pieces 3 are formed. Provide a cut B for this purpose. Then, after pressing upwardly protruding ribs 4 into each of the strip-shaped pieces, both ends of each piece are bent upward to form the outer regulating piece 2. During this step, when pressing the ribs 4, each piece of the spacing holder 1 slightly shrinks in its width dimension, the cut A becomes the spacing C, and the uncut portion 5 is stretched in the same direction. and its wall thickness decreases.

Now, when the spacing holder connected body formed in this way with 10 consecutive spacing holders 1 is broken off during use, the thickness of the iron plate between each spacing holder 1 is Interval C with approximately the same dimensions as
is formed, when cutting the uncut portion 5, the uncut portion 5 can be cut simply by bending force without the opposing end surfaces of the spacing holder 1 interfering with each other, and each spacing holder 1 can be easily broken off by bending, and the spacer retainer 1 can be easily broken off by bending.
It is possible to reliably recognize each sheet and fold only the required number of sheets.

Furthermore, by stacking and bundling a plurality of spacer retainers, it is possible to omit necessary containers, etc. when packing the spacers, and the total quantity of the spacer retainers 1 can be accurately determined by counting the number of sheets. It is also easy to understand. In this embodiment, the number of steps can be reduced to one-tenth that of the conventional method.

Therefore, this spacer connected body can omit the conventional work of lining up and boxing each spacer 1, and can also omit containers such as boxes and bags, thereby significantly reducing the material costs, time, labor costs, etc. required for packaging work. Furthermore, since the quantity can be managed in units of 10, the exact number of spacer 1 can be easily grasped, and therefore surpluses and shortages can be prevented in advance.

Note that, as shown in FIG. 3, if broken line-shaped press scratches 6 are formed in the uncut portion 5, each spacer holder 1 can be more easily broken off from the spacer holder assembly during use.

Effects As detailed above, this invention ensures that when each spacing holder is broken off from the spacing holder assembly when the spacing holder is used, a sufficient visible gap is formed between each spacing holder. Therefore, when cutting the connecting portion, the connecting portion can be cut simply by bending force without the opposing end surfaces of the spacing retainers interfering with each other, and each spacing retainer can be easily broken off by bending. At the same time, each spacer can be reliably recognized one by one and the required number of sheets can be broken off. In addition, it is possible to reduce costs such as material costs, time, and labor costs required for packaging the spacer, and also has an excellent effect of preventing the occurrence of excess or deficiency in quantity.
