Abstract

PROBLEM TO BE SOLVED: To form a ventilating opening having an improved ventilating function, and to facilitate the forming operation for a continuous footing by gripping the section to be fixed of a frame body, on which a screen is mounted detachably, by a reinforcement and burying the section to be fixed and placing concrete. SOLUTION: In a frame body 32 having a rectangular shape in a front view and length approximately corresponding to the width of a continuous footing 6 and being made of stainless steel, the whole circumferences of intermediate sites are constricted in a V-shaped cross section and deepest sections are formed in clamped sections 7 in each surface of both opening sections 32a, 32b. Ribs 35 are formed on the whole circumferences in both opening sections 32a, 32b. A flange 34, to which tapped holes 34a are formed, is installed on the underfloor side of the clamped sections 7, and a screen 33 preventing the entrance and exit of rats, etc., is set up detachably by screws 10. Both sides of the frame body 32, which is disposed into the continuous footing 6 and in which the clamped sections 7 are clamped by assembling reinforcements 8 in parallel crosses, are fastened by form panels, and concrete is placed. Mortar 16 is applied and finishing is conducted as required. Accordingly, operation is conducted extremely easily, drainage is improved, and a ventilating function can be enhanced.

Incidentally, the screen 104 is damaged by corrosion due to aging, and there is a case where cleaning under the floor is required for termite measures or the like. Therefore, the screen 104 is preferably detachable. For this reason,
Underfloor vents such as No. 24 were devised. The underfloor ventilation port is provided with an elastic material made of rubber or the like at the time of placing the concrete at the screen mounting position of the base concrete, so that the end of the screen can be inserted into and removed from the elastic body. I have.

In particular, when the intermediate portion in the length direction is narrowed down to form a V-shaped cross section, the structure can be stabilized simply by assembling with a cross beam without providing a structure for locking a reinforcing bar. And the structure is simple, and the work is extremely easy. In addition, since the inner side surface of the frame body is also inclined so as to have a larger diameter toward the outer side, drainage is good, and the above-mentioned effect can be further enhanced. Further, since the wind blowing from the outside to the inside is given power, the ventilation function is also improved.

The rims 11a and 25 corresponding to the outer surfaces of the fabric base 6 in the frames 3, 22, and 32 have the fabric base 6 attached thereto.
Projections 12, 24, 28, 38 projecting from the outer surface are formed. In the first and second embodiments, the lip 11a
In the third embodiment, the decorative member 24 and the outer frame member 28 are attached. Therefore, the protrusions 12, 24, 28, and 38 can close the space between the cloth foundation 6 and the mortar 16 to be coated on the outer surface of the cloth foundation 6, and the gap between the cloth foundation 6 and the mortar 16 can be reduced. As described above, water can be prevented from entering, and the durability can be improved. Also, the appearance of the mortar can be enhanced by concealing the combination of concrete and mortar of different colors.

Further, since the tightening portion 7 (fixed portion) is formed by forming the peripheral surface of the frame bodies 3, 22, 32 into a V-shaped cross section, there is no need to provide a structure for locking the reinforcing bar 8; It can be fixed stably by crossing the girder, the structure is simple,
The work is very easy. In addition, the frames 3, 22, 32
The inner side surface is also inclined so as to have a larger diameter toward the outer side, so that drainage is good, and the effect of improving the durability can be further enhanced. In addition, since the wind blowing from the outside to the inside is given power, the ventilation function can be improved. In forming the tightening portion 7, the above-described effect can be expected even when the entire circumference is not narrowed, and only the lower surface is narrowed to form a V-shaped section.
