Abstract

(57) [Summary] [Purpose] Form a round separator on one side with a slope on one side or with a slope on both sides without using a sloped plastic cone. [Structure] Bend one or both sides of the round separator according to the slope of the mold.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a circular separator used when assembling a formwork having a slope in formwork assembling work for concrete work.

[0002]

[Prior art]

 When concrete is poured into the formwork, the formwork tries to spread out laterally.Therefore, conventionally, cutting separators were used on both sides and reinforcing bars of the same thickness were used between them, and the method and gradient of welding the reinforcing bars and the separator were different. There is a way to level a round separator using a plastic cone.

[0003]

[Problems to be solved by the device]

 With the conventional method of welding the reinforcing bar and the round separator, the strength of the welded part is weakened, and if a graded plastic cone is used, the load during or after the concrete is driven will be applied to a part of the nut of the home tie. However, there was a problem that the structure of the home tie was not preferable from the viewpoint of safety.

According to the present consideration, the load of concrete is applied to the entire surface of the nut of the home tie, and the original safety of the home tie can be achieved.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a round separator is bent according to the inclination of the formwork, and one side or both sides is bent near the end of the threading according to the inclination of the formwork.

[0006]

[Action]

 By bending the round separator, a normal plastic cone (without a slope) can be used, and when using a plastic cone (c) with a slope, the load is transmitted to the entire nut of the compared tie, and from the viewpoint of safety, the home tie is also used. It is preferable because of its structure.

[0007]

【Example】

 An embodiment will be described with reference to the drawings, in which FIG. 1 is before assembly when using a sloped plastic cone (c).

FIG. 2 is when assembled using a graded plastic cone (c), where the graded form (d) and washer (g) are parallel but the home tie (f) is water. Since it is flat, it does not form a right angle with the washer (g). Therefore, the nut (h) that is perpendicular to the home tie (f) and the washer (g) are in contact with each other in the lower part, but are separated in the upper part, so the nut is separated. A load is applied to a part of (h). This degree of separation becomes worse as the gradient increases.

FIG. 3 shows a round separator (i) for one-sided gradient and a round separator (j) for two-sided gradient according to the present invention.

FIG. 4 shows the case where the round separator (i) according to the present invention is used, because the form (d) and the washer (g) are parallel, and the home tie (f) and the washer (g) are at right angles. In addition, the entire load is applied to the nut (h) of the home tie (f).

[0011]

[Effect of device]

 The present invention has the following effects due to the structure described above.

Since the home tie and the washer are at a right angle, the load is applied to the nut of the home tie over the entire surface.

The nut may be tightened by a conventional tightening method.

The conventional round separator would not be horizontal without the use of the graded plastic cone, as it would be perpendicular to the graded form, but the round separator of the present invention would not have a graded plastic cone. Level.

The round separator of the present invention is just the same as the conventional round separator, and does not require any special tool or skilled worker.
