Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel laid on a work floor of a food factory, a kitchen, a chemical factory or the like.

[0002]

BACKGROUND OF THE INVENTION The floor surface of a food factory is generally made of cement-based material, but it is always exposed to hot water, steam, disinfectants, food additives, etc. Since it is used under severe conditions such as being frequently subjected to an impact load due to falling of articles, it is the current situation that damage and deterioration progress rapidly and repairs must be made in a short period of time.

In addition, at the time of renovation, the work must be completed in a short time so as not to hinder the operation of the factory. However, since it involves a very laborious process, the work cannot be completed in time in many cases. . Further, even after the repair, there is a problem that cracks occur due to repeated expansion and contraction of the mortar, and the water entering from the cracks causes peeling at the boundary with the base surface.

Although the floor surface may be made of a resin material such as an epoxy resin, an MMA resin, a urethane resin, a vinyl ester resin, or a polyester resin, the softening point of the resin material is as low as about 80 °. , Touching hot water may expand and raise the floor surface, limiting its use. In addition, it produces an odor, which is not preferable for food factories.

The frame 1 is formed by pressing a stainless thin plate having a thickness of about 0.5 to 2 mm into a box shape, and is provided with a large number of non-slip projections 2 on its surface. Further, the lower end of the side surface of the frame body 1 is bent toward the front surface side to form a substantially U-shaped return piece 3. The return piece 3 has an appropriate resilience so that the floor panels can be arranged at appropriate intervals without rattling.

In the floor panel shown in FIG. 1, the base portion of the return piece 3 is rounded, but this portion may be rounded or bent at a right angle. Reference numeral 4 denotes a block body provided in the frame body 1. Although a block body formed by a precast method may be housed in the frame body 1, the block body 4 of this embodiment uses the frame body 1 itself as a mold. It is constructed by filling it with cement mortar and then applying vibration to compact it.

As the material of the block body 4, in addition to cement mortar, lightweight cement mortar using lightweight aggregate, concrete in which gravel is mixed in cement mortar, epoxy resin, polyester resin, MM
Resin A, and resin concrete in which silica sand or the like is mixed with these resins can be used. The frame body 1 has a tapered side surface so that the width in the vicinity of the opening is slightly smaller than the width on the inner side, so that even if the block body 4 is solidified or contracted, the frame body 1 is framed. It does not fall out of body 1.

Next, a method for joining floor panels to each other will be described with reference to FIGS. First, mortar or concrete is cast on the ground to form a substantially horizontal base surface 5. Then, an adhesive layer 6 made of epoxy resin, cement mortar, etc., which also serves as a correction for the unevenness, is provided on the base surface 5, and a floor panel is laid on the base surface 5 with the return pieces 3 abutting each other.

The butted return pieces 3 are in a pressure-bonded state due to the elasticity of each other. As shown in FIG. 3, a silicone rubber sealing material 7 is attached to this, and a stainless cap 8 having a U-shaped cross section is fitted to cover the sealing material 7, as shown in FIG. The sealing material 7 and the cap 8 may be integrated in advance.

As described above, in this embodiment, since the floor surface is formed by combining the panels coated with stainless steel, it is much more durable than the conventional structure, for example, heat resistance, water resistance and chemical resistance. The workability is simple and the work is easy because the floor panels are lined up and the joints are closed.
Repair work can be completed within a limited time.

Even if moisture enters between the sealing material and the floor panel, the return piece 3 surely blocks the moisture, so that the moisture does not reach the base surface, and therefore the boundary is not reached. No peeling occurs on the surface, and the floor panel is not displaced or lifted. Further, deterioration of the base concrete can be effectively prevented. 5 and 6 show the second aspect of the present invention.
FIG. 5 is a sectional view of the floor panel according to the embodiment, and FIG.
