JPH0578808U - Small cover for formwork single pipe - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a mouthpiece cover for a formwork single pipe that is convenient as a formwork single pipe and has excellent durability and handleability. [Structure] A hard synthetic rubber material with moderate elasticity,
At the tip of the tubular body 8 which is tightly inserted into the single pipe small mouth, the diameter of the pipe 8 which is continuous with the inner diameter of the tubular body 8 through the slope cut 9 for reinforcement corresponds to the outer diameter of the single pipe small mouth. 10 is integrally shaped so that the single-tube mouthpiece has a cover 7 having elasticity matching the outer diameter of the single-tube mouthpiece, and by covering the single-tube mouthpiece, it is easy to use, durable, and easy to handle. It was suitable.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an edge cover for a single mold tube.

[0002]

[Prior Art]

 Assembling / disassembling / transporting a single formwork pipe is frequently repeated, but a drop during these operations is unavoidable. If the small end of this single pipe is left open, concrete will be clogged with the small end of the single pipe and become heavy. If such a small single pipe becomes heavy, it will be difficult to carry and carry. There is a disadvantage that if a small edge of a single pipe hits the surface of the floor directly, it will be scratched, and if the small portion of the floor is directly ground under the concrete, it will be useless to repair the flaw. Therefore, a protective plastic cup made of hard plastic, which has been developed to prevent damage caused by a bare single-ended tube, has been used as a crown for the single-mold form. The protective cap body is introduced in FIGS. That is, the protective cap body 1 hangs a skirt portion 4 which crowns the end of the single pipe 6 from the peripheral edge of a large-diameter hemispherical portion 3 which is integrally shaped at the tip of the pipe body 2 which is tightly fitted inside the mouth of the single pipe 6. It is set up. The shaped projections 5, ... Are provided for tight fitting from the middle of the tube 2 to the hemispherical portion 3 at the tip.

[Problems to be solved by the device]

 Since what has been described in the prior art is mainly intended to prevent injuries in safety at the time of contact, even if it is applied to a formwork single pipe, the inconveniences listed below occur. In other words, since the end face of the single pipe is rounded to prevent injury, it is molded with a larger diameter than the single pipe (skirt part 4), so the single pipe has a flange at the end. There is a problem of being injured or caught when it comes into contact with the ledge, and it is inconvenient because it is impossible to remove the clamps and other equipment, and it is made of hard plastic, so it is easily damaged when dropped, and the set is easily removed. Is difficult. The present invention has been made in view of the above problems of the conventional technique. The purpose of the present invention is to prevent detachment from the end of a single pipe, easy attachment / detachment, and being difficult to be damaged by dropping. It is intended to provide an edge cover for a single formwork tube.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the mouthpiece cover for a mold single pipe in the present invention is made of a hard synthetic rubber material having an appropriate elasticity, and the inner diameter of the pipe body is inserted into the tip of the pipe body which is tightly inserted in the single pipe mouth. And a flat circular lid portion having a diameter continuous with a bevel cut for reinforcement and the outer diameter of the single pipe small diameter is integrally formed. It is advisable to provide a tight fitting projection ring on the peripheral surface of the tubular body.

[0005]

[Action]

 The fore edge cover of the present invention is easy to put on and take off because it is made of a hard synthetic rubber material having appropriate elasticity. Also, since the mounting mode is flush with the single pipe, it is easy to use because it does not get caught and the clamps can be pulled out.

[0006]

【Example】

 Examples will be described with reference to the drawings. 1 and 2, the edge cover 7 of the present invention is made of a hard synthetic rubber material having an appropriate elasticity, and is provided with a reinforcing sloped cut at the tip of the tube body 8 which is tightly inserted in the edge of the single tube 6. A flat circular lid portion 10 that is continuous through 9 is integrally formed. The diameter of the flat circular lid portion 10 matches the outer diameter of the single tube 6. Then, when the fore-edge cover 7 is attached to the fore-edge of the single tube 6, the fore-edge is covered flush with the fore-end as shown in FIG. Therefore, there is no catch, and the attached clamp or the like can be pulled out from the end of the single tube 6. Also, since it has elasticity, it can be easily attached and detached, has excellent impact resistance, and has durability. Incidentally, reference numeral 11 in the drawing denotes a tight fitting projection ring which is preferably formed on the peripheral surface of the tubular body 8 in an appropriate number.

[0007]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. In other words, since it is a dense insertion of elastic plugs, it is easy to attach and detach, it does not displace due to impact, and because it is mounted on the surface of a single pipe, it is possible to remove objects such as catches and clamps that cannot be removed. It is inexpensive and can be color-coded.
