DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inspection port including an inner lid and an outer lid, and particularly to an inspection port for a unit bus.

[0002]

2. Description of the Related Art Conventionally, an inspection port including an inner lid and an outer lid has been known. The inspection opening is used to remove the outer lid and the inner lid when connecting, inspecting, or repairing the piping, and to perform those operations. The inspection opening is provided with a concave portion on a part of the wall surface, and the opening is provided in the concave portion. The outer lid fixed to the inspection opening is not easily removed by a user. The lid or the outer lid is sealed by treating the periphery of the lid with a sealing material so that water, water vapor and the like do not enter inside. However, if the inner lid is tightly sealed, it takes a great burden to remove it, and the inner lid is opaque such as metal or plastic, so that there is a problem that the inner state cannot be confirmed from the outside. .

[0003]

SUMMARY OF THE INVENTION The present invention is to solve such problems of the prior art, and it is an object of the present invention to efficiently perform work for connecting, inspecting, or repairing piping. I do.

[0004]

Means for Solving the Problems In order to achieve this object, an inspection port comprising an opening, an inner lid and an outer lid,
This inspection port has two stepped concave portions, the inner lid is adhered to the second concave portion with an adhesive or an elastic agent, and the outer lid is disposed in the first concave portion. It is.

[0005]

According to the present invention, since the inner lid is treated with the release agent or is a transparent inner lid, the work of connecting, inspecting, or repairing the piping can be efficiently performed.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The inspection port preferably has a recess, but the opening for attaching the inner lid preferably further has a recess. The pressure-sensitive adhesive provided in the opening may be only a pressure-sensitive adhesive, but is preferably a pressure-sensitive adhesive applied to an elastic material impermeable to water from the viewpoint of sealing properties. As the elastic material, a closed cell foam of a synthetic resin such as urethane foam is preferable. Conventionally used pressure-sensitive adhesives are used, but rubber-based pressure-sensitive adhesives, for example, butyl rubber are preferred. The inner lid may be entirely treated with a release agent, but from an economical point of view, it may be at a portion corresponding to the adhesive stuck around the opening.
The release agent may be any as long as it can be peeled off from the adhesive, but a silicone-based release agent is particularly preferred.
The transparent inner lid may be any as long as the state of the pipe can be checked from the outside, but plastic is particularly preferable from the viewpoint of work and the like. As the plastic, a plate material, a film material, or the like is used, and as the material, an acrylic resin is preferable. The inspection port is an inspection port in the unit bath that is provided to enable connection work between the pre-water supply hot water supply pipe connected to the faucet fitting of the unit bus and the water supply hot water supply pipe on the building side after the unit bus is assembled Is particularly preferred.

Embodiments will be described below with reference to the drawings. FIG. 1 is a perspective view showing an inspection port provided in the unit bus, FIG. 2 is a configuration diagram showing a middle lid and an outer lid attached to the inspection port, and FIG. 3 is a part of a circular portion indicated by a dotted line in FIG. It is an enlarged view.

Hereinafter, the present invention will be described with reference to examples. FIG. 1 shows a state in which the lid of the inspection port 2 of the unit bath 1 is removed, and a mounting bracket 6 is provided at the inspection port.

The attachment of the outer cover 4 and the inner cover 5 to the opening 3 will be described. The first opening 7 has a first concave portion 7 (see FIG. 3) and a second concave portion 8 to which the inner lid 5 is attached. A butyl rubber 9 (FIG. 3) is adhered around the second concave portion 8 so that no gap is formed, and an acrylic plate middle lid 5 treated with a silicone resin is attached to the inspection hole 2 (FIG. 3).
Then, the inner lid 5 is joined and sealed (see FIG. 2).

Next, the outer cover 4 is embedded in the first recess 7, and the outer cover 4 is attached to the unit bus 1 by the mounting bracket 6 provided in the first recess 7.

As described above, since the release agent is applied to the inner lid, it can be easily removed as necessary to perform repair and inspection, and the opening can be removed again without treating the opening with an adhesive. A lid can be attached, but an adhesive may be applied to the inspection port in some cases. Further, since the inner lid 5 is made of an acrylic plate and is transparent, the state inside the inspection opening can be inspected with the inner lid attached.

[0012]

According to the present invention, since the inner lid is treated with the release agent, the inner lid can be easily removed when water leakage or the like occurs, and the inner lid can be sealed as it is, so that the efficiency is improved. Work can be done. Furthermore, even if the operator is unfamiliar, the work can be redone differently from the conventional one because the work is easy to attach and detach, so that the construction can be performed more reliably for a beginner. Further, when the inner lid of the present invention is transparent, with the inner lid attached, in particular, a pre-water supply hot water supply pipe connected to the faucet fitting of the unit bath, and a water supply hot water supply pipe on the building side, An inspection port in the unit bus provided to enable connection work after the unit bus is assembled is particularly preferable. In addition, material costs and construction costs can be reduced as compared with conventional ones.
