JPH04140364A - Installation of upper end holder for waterproof layer protective panel rising from floor - Google Patents

Abstract

PURPOSE:To temporarily secure an upper end holder to the inside of form without temporary fastening by means of nails by nailing an elastic rod to the inside of form under cog and engaging an upper end holder with the elastic rod. CONSTITUTION:A protective panel 4 is disposed from a floor 1 on the surface side of rising waterproof layer 3, and the upper and lower ends of protective panel 4 are supported by holders 8, 5. Next, an elastic rod 11 is nailed to the inside of form 10 under cog, and the upper end holder 8 is engaged with the rod 11. Then, concrete is poured in the form 10 under cog. The upper end holder 8 is secured by inserting a protruding strip 15 into the concrete layer. A draining recess 16 is formed on the floor surface of upper cog 9. This method reduces the risk of crack because the upper end holder 8 is secured temporarily without nailing, and eliminates the need for installing a separate draining member.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a light-shielding and water-resistant panel that protects a waterproof layer formed on the inner surface of a portion rising from the floor, such as a flat roof parabet or a rooftop tower. This is an explanation of how to install the upper end holder.

[Conventional technology]

A waterproof layer is formed on the inner surface of the rising part of the flat roof, and the surface side of this rising waterproof layer is covered with a light-blocking and water-resistant protection panel, and the upper and lower ends of this protection panel are covered with holders. A structure is being considered in which the lower end holder is fixed to the floor while the upper end holder is attached to the underside of the chin at the upper end of the portion rising from the floor.

In addition, the upper end holder is temporarily fixed by nailing to the inner surface of the lower chin formwork part of the mold for forming the rising part from the floor, concrete is poured into the formwork, and the formwork is removed after the poured concrete has hardened. It is also conceivable that the upper end holder is buried and supported under the chin at the upper end of the rising part.

[Problem to be solved by the invention]

By the way, the bottom holder can be drilled with a hole in the bottom plate to pass through the screws for fixing it to the floor, but if the top holder is temporarily nailed to the inner surface of the mold for forming the rising part, the top holder will not open. In the case of P■C, there is a risk of cracking, and in the case of metal, it is necessary to drill holes for nailing in advance.

This invention attempts to solve the above-mentioned problems, and its purpose is to temporarily fix the upper end holder to the inner surface of the form without being able to temporarily fix it by nailing to the upper end holder itself.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides that the upper end holder of the protective panel is arranged in advance on the inner surface of the lower jaw molding frame of the jaw molding mold at the upper end of the rising part. In addition, it fits into an elastic rod-shaped body nailed to the formwork and whose width in the width direction is slightly larger than the inner width of the upper end holder and whose height is lower than the depth of the upper end holder, and is used to fit the upper end of the protection panel. The opening end of the recess is brought into close contact with the inner surface of the formwork, and the outer surface of the upper end holder is provided with a protrusion to prevent it from coming off, which penetrates into the concrete layer to be poured. A floor section with drainage recesses formed between the sections, with only the upper end holder remaining embedded in the lower part of the jaw, which is formed by pouring concrete into the formwork and removing the formwork after hardening. This is a method for installing a holder at the upper end of the protective panel for the waterproof layer at the rising part.

[Effect]

An elastic rod is nailed and fixed to the inner surface of the under-chin formwork at the upper end of the rising part from the floor where the jaw protrudes, and the upper end holder is fitted to this rod-like member, and the front edge of the upper end holder is attached to the formwork. When concrete is injected into a formwork that forms a rising part from the floor, and the formwork is removed after the injected concrete has hardened, the rods on the inside of the formwork can be removed while remaining fixed to the formwork. Only the upper end holder remains embedded in the lower surface of the jaw.
