Abstract

<P>PROBLEM TO BE SOLVED: To solve the following inconveniences: a conventional plastic form for concrete cannot be extended upward, and cannot be detached from the concrete. <P>SOLUTION: There is provided a new form board 1 for concrete, or the like, to solve the inconveniences. According to the structure of the new form board, a vertical groove is formed at the center of a single plastic board, and reinforcing plates are arranged along peripheral sides of the same. Further each reinforcing plate has holes bored therein. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention relates to a formwork plate for concrete, and by adding a device that has a plurality of holes in a central portion and a portion around a single plate made of plastic, and a device that has a vertical groove in the central portion. The size of the plastic formwork can be removed after the concrete has been set if it is used not only on the front side but also on the back side by changing the size with only one type of board combination. It is a thing. In some cases, a reinforcing plate having a plurality of holes may be attached to the side.

Conventionally, as a formwork material for concrete, an object that can be expanded horizontally by using a joint and a rectangular object or a nail is used.

However, with the conventional plastic formwork, the size can only be increased laterally and cannot be increased by adding upwards. Also, the plastic formwork itself cannot be removed after the concrete has hardened. An object of the present invention is to solve this inconvenience that it is impossible to remove this concept depending on its free size and use.

In order to solve this problem, the invention of claim 1 is characterized in that a groove is vertically formed in the central portion of a single plastic plate, a reinforcing plate is formed around and a hole is formed in the reinforcing plate portion. It is a functional plastic form plate.
If this hole is fixed with Claim 2, the size can be changed, and if Claim 3 is added, it can be reinforced to prevent swelling when concrete is put in, and the strength can be maintained even if it is increased.

In addition, the second and third aspects of the present invention can determine the alignment position and also serve as a reinforcement by using a dedicated fixing tool.

Further, according to the fourth aspect of the present invention, when the product is turned upside down, the product can be removed after the concrete has hardened, so that no plastic remains in the concrete.

It was difficult to have a structure that can not be removed simply by spreading it sideways according to the present invention, but if you use this formwork material, the size of the formwork material can be expanded both horizontally and upwards. If you use it upside down, you can remove only the formwork later. The previous inconvenience of not being raised up and being able to be removed is eliminated.

FIG. 1 (1 to 4) is a product drawing of the concrete form material whose size can be freely changed, written in a trigonometric method. As shown in the drawing, the center of the plate part is characterized by a groove and a hole, and a central reinforcing plate and a plurality of holes that are open in the reinforcing plate part. The size can be changed freely by inserting and fixing the bolts and nuts.
(Bend the groove and use it as a corner. Use it as a straight joint.)

2 (5 to 7), two holes attached to the reinforcing plate are combined and inserted therein, and can be firmly fixed at the insertion taper portion of FIG. 2 in FIG. 3 (8 to 9).

4 (10 to 11) are used for positioning of an angle when used as a corner, and the holes are aligned, and FIG. 2 is inserted to hold FIG. 3 in the groove portion.
What is stopped at that time can be stopped not only by a dedicated stopper but also by a commercially available bolt and nut.

5 (12 to 13), when used as a joint, it is used as a reinforcement in the part where the central groove is cut, and a special stopper or bolt nut is put in the hole part and firmly fixed. Further, FIG. 2 is inserted into the corner hole and the reinforcing plate of the joint or the joint and the joint, and FIG. 3 is inserted into the groove portion. The thing to stop at that time can be stopped with a commercially available bolt and nut instead of a dedicated stopper.

Fig. 6 (14-15) is a side view of the top and bottom views of 16 assembled (fixed top and bottom 8 plates) with a flat surface on the outside and a reinforcing plate on the inside. It can be seen that it is assembled on the top, and this method leaves the concrete as it is.

FIG. 7 (16 to 17) is a view seen from above and a side view of an object assembled and fixed by combining 16 pieces (upper and lower 8 pieces) with a plane inside and a reinforcing plate facing outside. It can be seen that it is assembled sideways and above, so that it can be taken out once the concrete has hardened, and it can prevent the plastic from being left on the concrete.

The material for the concrete mold material may be a normal material such as plastic.
Moreover, you may make it a type | mold close | similar to R instead of a corner | corner by attaching a some groove | channel vertically to the main-body center part.

The concrete form plate, the dedicated stopper and the dedicated auxiliary plate according to the present invention can be industrially mass-produced, and thus have industrial applicability.

It is a drawing written in trigonometry of a concrete formwork plate with a reinforcing plate with a groove in the center and a hole in the side. This is a drawing in which triangulation is used for a dedicated stopper that is inserted into an overlapping hole when a concrete formwork plate or a reinforcing plate is combined. It is a drawing in which a front view and a side view of a dedicated and fitting presser to be inserted to fix a dedicated stopper inserted in an overlapped hole when a concrete form plate or a reinforcing plate is combined are written. It is the front view and side view of a corner reinforcement board which are used when a concrete formwork board is pushed and bent along a groove. It is a front view and a side view of a reinforcing plate for straight that is used so that the concrete mold plate does not bend due to pressure so that it does not bend from the groove portion, and the place where two sheets are combined does not bend due to pressure. It is the upper side figure which looked at the thing which combined the reinforcement board part with which the hole of the concrete formwork board opened toward the inner side, and 16 sideways, and the side view seen from the side. It is the upper side figure which looked at the thing which combined the reinforcement board part with which the hole of the concrete formwork board opened outward 16 sideways, and the side view seen from the side.
