する等の問題点があった。[Problem 9 to be solved by the invention: When mortar is poured into a formwork, air bubbles in the mortar collect on the surface of the formwork plate, and after the mold is removed, the surface in contact with the formwork plate, especially on an inclined surface. Many pockmarks occur on the surface, which impairs the beauty of the structure, and the pockmarks become weak points, reducing durability.

、繰返し使用もむずかしく、コストの低減が求められて
いた。Various countermeasures have been proposed for this problem. For example, by providing drainage holes at predetermined intervals on the formwork board, the surface has ventilation holes.
There is a method of attaching a porous material made of a fibrous material having water permeability. It is known that this means prevents the occurrence of surface pockmarks by discharging air bubbles in mortar, and improves surface strength by removing excess water. but,
In this method, the efficiency of exhaust and dewatering is not necessarily high enough, and it is necessary to drill many drainage holes in the formwork plate, making it difficult to use the formwork plate for other purposes and reducing its operating rate. It had the disadvantage of being low. In addition, porous materials can be filtered,
Thick fabrics with both water-permeable functions are expensive (approximately 1,500 to 2,000 Fl/m2 in material cost alone), and are difficult to use repeatedly, so there has been a demand for cost reduction.

せしめることができる型枠を提案するにある。This invention was made in view of the above circumstances. The purpose of this method is to reduce the cost of the formwork because it does not require the use of special formwork plates with numerous drainage holes, and to improve the efficiency of evacuation of bubble air and dewatering of excess water. The purpose of the present invention is to propose a formwork that can significantly reduce the occurrence of surface cracks and improve surface strength and workability.

適宜間隔の凸部5の上面に貼着して取付けられる。The filtering material layer is made of a material through which solid particles in mortar do not substantially pass through, but through which moisture and air permeate. As such a material, for example, a fiber density of 20 to 10 using synthetic fiber multifilament system of 70 to 500 deniers is used.
A plain woven fabric of 0 threads/2.54 cn is preferred. The drainage material layer is shown below. In FIG. 1-1, the drainage material layer 2 is attached to the inner surface of the form board 1 with the projections 5 facing upward, and the filtering material layer 3 is attached by adhering to the upper surface of the projections 5 at appropriate intervals.

A formwork board 1 constituting one vertical side of the formwork has a drainage material layer 2 and an overfilling material layer 6 laminated in this order on its inner surface, and a drainage hole 6 is provided at the lower end of the formwork board 1. be. The concrete slurry 7 poured into the formwork comes into contact with the filtering material layer 6, and the air that collects at the interface passes through the filtering material layer 6 and enters the drainage material layer 2. At the same time, excess water in the concrete slurry 7 is pushed by internal pressure. It passes through the filtering material layer 3 and enters the drainage material layer 2. This air and excess water are discharged through drainage holes 6 at the lower end of the form plate.

なり、作業性からも経済性からも好適である。The formwork plates shown in Figures 2-2 and 3-2 are designed to drain water by extending the drainage material layer 2 all the way to the lower end of the formwork, and these types especially have drainage holes in the formwork. There is no need to open it, which is favorable from both workability and economical points of view.

Therefore, concrete structures cast using this formwork have fewer pockmarks on the surface and have significantly improved strength. In addition, the drainage material layer acts as a heat insulating layer and is effective for curing the initial concrete.
