Description

[Detailed Description of the Invention] The present invention relates to a concrete formwork panel suitable for use mainly in wall construction.

Conventional pre-formed frame panels come in a variety of materials and shapes, such as plywood, aluminum, metal, and resin. Each of these had drawbacks that needed to be resolved, such as difficulty in processing, aluminum being expensive, metal being heavy, and resin having low rigidity.

Therefore, the present invention is an improvement to eliminate the drawbacks of the above-mentioned existing panels, and its purpose is to provide a formwork panel that is highly rigid, lightweight, and can be placed low.

The drawings showing the embodiments of the present invention will be explained below.
In FIGS. 1 to 3, panel A is formed by fixing a face plate 1 made of a galvanized iron plate, side frames 2, and end frames 3 to desired vertical and horizontal dimensions by welding or the like. On the back side, that is, on the back side of the face plate 1, hole-shaped rib members 4 and type 1 rib members 5 and 5', which are made of galvanized iron plates and have a box-shaped cross section and a type 1 cross-sectional shape, respectively, are welded in parallel in the longitudinal direction. A plurality of steel rods 6゜6' are fixed to each other, and further penetrate through each of the rib members 4, 5.5' in the short axis direction and through the plurality of steel rods 6゜6'.
6n are horizontally fixed in the short direction at appropriate intervals.

As shown in the figure, the hole-shaped rib material 4 is formed in a long length from a top wall 7 and both side walls 8, 8' which are flatly bent from both ends of the top wall 7, and is provided on the back surface of the face plate 1 on its lateral sides. The top wall 7 is fixed vertically by welding or the like at an intermediate position where the width is bisected, and the two type 1 rib members 5° 5' are connected to the hole type rib member 4.
The rib members 4, 5, .
The side ends in the longitudinal direction of panel A are fixedly integrated with the inner wall surface of the end frame 3 by welding or the like, and the hole-shaped rib members 4 and type 1 rib members 5.5' This is to reinforce the face plate 1 and side frame 2 against buckling in different directions.

Further, the steel rods 6, 6', . It is constructed in the width direction of A, and is fixed and integrated with each rib member 4, 5.5' by welding or the like, and both ends are fixed to the side ends 2 by welding or the like. 6゜6′・・・・・・
6n is the face plate 1 and end frame 3 for buckling in the width direction of panel A.
It is intended to reinforce the

As clearly shown in the enlarged cross-sectional view in FIG. It is fixedly provided near the lower horizontal bent part of the panel 5' and the lower side of the side frame 2, so that it can be grasped from the back side of the panel A, so that it can be conveniently used for carrying the panel A. It has become.

In this case, as mentioned above, the upper and lower horizontal bent portions of each rib member 4, 5.5' are integrally fixed to the face plate 1 and the steel rod 6. These reinforcing effects are particularly rational and excellent.

As shown in the example of use in FIG. 4, when constructing a wall 9 horizontally, the hole 11 of the separator 10 supported at an appropriate interval on both sides to form a concrete placement gap is inserted into the hole 11 of the above-mentioned box-shaped rib. It is formed to penetrate from the top wall 7 of the material 4 to the face plate 1,
This is to prevent the occurrence of a bulging phenomenon due to over-tightening of the formwork fastener 12 on the separator 10 portion.

However, in the illustrated wall form erection, the end of the separator 10 provided with the form support connector 13 is inserted into the hole 11,
The thick end material 14 is attached to the rib portion 151 of the hole-shaped rib material 4.
, 5' rib part, side frame 2, and end frame end face, and tighten the formwork tightening tool 12 to the separator 10, so it can be tightened evenly, so the tightening is sufficiently strong. Even though this is obtained, the phenomenon of bulging of the face plate 1 due to over-tightening of the formwork fasteners 12 does not occur.

Since the concrete form panel according to the present invention is constructed as explained above, the hole-shaped rib members 4 and the L71J rib members 5, 5' made of iron plates are arranged in parallel in the longitudinal direction of the panel.
and a steel rod 6゜6' placed perpendicularly to these...
. . 6n resists buckling in the vertical and lateral directions, the other face plate 1 and side frame 2 . Since the end frame 3 is also made of a rigid iron plate, high rigidity can be obtained. Therefore, by making the panel longer and larger, it is possible to shorten the interval between the ends, and the floor When used for this purpose, the shoring can be omitted and there is no risk of buckling, so the number of separators can be reduced, and the box-shaped rib material 4 is arranged along the hole drilling position of the separator. Since the separator hole 11 is provided through the rib material 4 and the face plate 1, it is possible to completely eliminate the bulge phenomenon of the face plate 1 that occurs in the existing panel due to over-tightening of the formwork fasteners. Therefore, when making a formwork panel for a wall, the inner butterfly can be omitted, and the steel rods 6...6n not only increase the rigidity of the panel, but also serve as gripping parts when carrying the panel. It has many excellent practical effects, such as being able to be used conveniently.
