Abstract

PURPOSE:To prevent a danger of slipping when panels are stacked on each other and stored by arranging antislipping members which are higher than side wall plates and slightly project from the side wall plates in a horizontal plane on the opposite side of a concrete placing surface of a face plate. CONSTITUTION:Cylindrical antislipping members 15 are embedded in cylindrical holding parts 17 arranged in both end parts of reinforcing ribs 7 positioned outside. In that case, tip parts are slightly projected from side wall plates 3 and 5 in a horizontal plane. The antislipping members 15 are formed of a rubber-like elastic body of natural rubber, synthetic rubber or thermoplastic elastomer. At this time, a through-hole 18 is arranged in a central part, and is used as a release margin when an upper surface of the antislipping members 15 are pressed. Then, when panels are stacked, the antislipping member 15 are brought into contact with the side wall plates 3 and 5 and the ribs 7 and 9 before a face plate 1 is brought into contact with them. Therefore, the panels can be prevented from being dislocated or slidingly dropped at storage and transport time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic concrete formwork panel used for producing a concrete structure such as an outer wall of a building by pouring concrete. The present invention relates to a non-slip panel for plastic concrete formwork that does not slip accidentally.

[0002]

2. Description of the Related Art Conventionally, a formwork panel used for pouring concrete generally has a face plate size of 600 m.
It is formed in a rectangular shape having a size of m × 900 mm, 600 mm × 1500 mm, or 600 mm × 1800 mm, and these panels are appropriately assembled and used as an outer wall frame of a building. And, generally, a wooden panel formed by reinforcing the four circumferences and the inside of a face plate such as plywood with a reinforcing material such as square timber is used,
In addition to the wooden panels, metal panels and, in recent years, lightweight and easy-to-handle plastic panels are also used.

[0003]

Plastic panels, unlike wooden panels, have the advantage that they do not easily rot and do not require repair, and they are lightweight, recyclable, and excellent in durability. However, the conventional plastic panel has a problem that it is slippery due to the nature of its material. The problem of slipping is slipping when carrying it by hand, sliding between panels when horizontally stacking and storing the panels, sliding when placing the panel on another object,
It is possible that slippage occurs when hoisting multiple stacked panels with a crane. In particular, slippage between panels when stacked and slippage with other objects cause a load collapse and become dangerous.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a non-slip panel for plastic concrete formwork which is free from the risk of slipping when the panels are stacked and stored. .

[0005]

The present invention has the following configuration to achieve the above object. That is, the non-slip panel for plastic concrete formwork of the present invention is a plastic concrete formwork panel in which side wall plates are provided on the four circumferences of the face plate, and the side wall plate is provided on the side opposite to the concrete placing surface of the face plate. It is characterized by disposing a non-slip member that slightly projects from the side wall plate in the horizontal plane. The anti-slip member may be formed in a cylindrical shape and may be embedded in a cylindrical holding portion integrally formed with a reinforcing rib provided inside the side wall plate such that the tip end thereof slightly projects from the side wall plate. In addition, the slip prevention member is formed in a sheet shape and fixed to the upper surface of the reinforcing rib provided inside the side wall plate, or a widened portion is formed on the reinforcing rib provided inside the side wall plate and fixed to the widened portion. Good. Further, the sheet-like anti-slip member may be formed in the reinforcing rib provided on the inner side of the side wall plate to form a widened portion having a concave portion on the upper surface and embedded in the concave portion. It is also possible to form the anti-slip member by applying it to the reinforcing ribs or the widened portions of the reinforcing ribs.

[0006]

Since the anti-slip member slightly protrudes from the side wall plate, the anti-slip member comes into contact with the anti-slip member when stacked horizontally, and works to prevent mutual slip.
