JP2000241286A - Convenient method for water leak inspection - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a convenient method for water leak inspection in which water leak from the structure or around the body sash can be inspected easily. SOLUTION: One end 5A of an adapter pipe 5 is set airtightly on the indoor side wall face of waterproof mortar 4 at point P and the other end 5B of the adapter pipe 5 is coupled with a suction hose 7. A negative suction pressure is supplied from an electric cleaner body 8 through the suction hose 7 in order to spray water onto the outdoor side wall face of waterproof mortar 4 at point P. Water leak is inspected based on discoloration or variation of blur in the adapter 5A before and after water spray.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple water leakage inspection method capable of easily inspecting the presence or absence of water leakage from around a body and a sash.

[0002]

2. Description of the Related Art When a window is installed in an opening of a building, a waterproof mortar is filled between a fitting such as an aluminum sash and a frame to obtain a required waterproof performance. However, when the construction is not perfect, water leakage from around the window frame occurs.

[0003]

In the prior art, this kind of water leakage is often found only when it actually rains or is exposed to strong wind and rain due to a typhoon, and this is easily inspected in advance. There was no way.

[0004] The present invention has been made in view of the above-mentioned problems of the prior art, and provides a simple water leakage inspection method capable of easily inspecting the presence or absence of water leakage from around a frame and a sash. It is in.

[0005]

A feature of the present invention for solving the above-mentioned problem is a method for inspecting the presence or absence of water leakage from around a frame and a sash. Set one end of the pipe in an airtight state,
A predetermined suction negative pressure according to the building height is applied to the other end of the adapter pipe, and water leakage from the body and the sash around the body in the adapter pipe when water is sprayed to the outside of the inspection site. The point is that the presence or absence is visually inspected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an explanatory diagram for explaining an example of an embodiment of a method for inspecting the presence or absence of water leakage from around a sash of a building according to the present invention. In FIG. 1, 1 is a building wall,
Reference numeral 2 denotes an opening for a window provided in the wall 1, and 3 denotes an aluminum sash frame for the window. A waterproof mortar 4 is filled between the aluminum sash frame 3 and the opening 2, thereby ensuring waterproofness between the aluminum sash frame 3 and the opening 2.

Whether the required waterproofness of the waterproof mortar 4 is ensured or not, that is, whether water leaks from the periphery of the aluminum sash frame 3 due to cracks or the like in the waterproof mortar 4 is determined. In order to perform the inspection, one end 5A of the adapter pipe 5 is set inside the waterproof mortar 4 which is the inspection site at a required location P so that the airtight state is maintained between the adapter pipe 5 and the waterproof mortar 4. In the present embodiment, an annular sponge 6 is provided between one end 5A of the adapter pipe 5 and the waterproof mortar 4, thereby maintaining an airtight state between the one end 5A of the adapter pipe 5 and the waterproof mortar 4. .

The other end 5B of the adapter pipe 5 is connected to a suction hose 7 of a household vacuum cleaner.
The inside of the adapter pipe 5 is brought into a predetermined negative pressure state by operating the vacuum cleaner main body 8 connected to. Instead of the vacuum cleaner body 8, the inside of the adapter pipe 5 may be brought into a negative pressure state by other means.

Reference numeral 9 denotes a negative pressure meter, which can display the negative pressure in the adapter pipe 5 with a meter.

In this state, water is sprinkled with a jug 10 outside the required portion P of the waterproof mortar 4 which is the portion to be inspected. It is visually confirmed whether there is no crack or the like at a required portion P of the waterproof mortar 4 and no water leakage occurs.

Therefore, anyone can easily inspect the presence / absence of water leakage and the degree of water leakage from changes in the color of the body surface before and after watering, oozing of water, and the like. If the above-mentioned inspection is performed by appropriately moving a required portion P of the waterproof mortar 4, the waterproof state of the entire waterproof mortar 4 can be inspected.

[0013]

According to the present invention, as described above, when water is sprayed to the outdoor side of the inspected site, a change state such as color or bleeding in the adapter pipe is visually detected, and the state of the body and the sash area are detected. Can be ascertained as to the presence or absence of water leakage and the degree of water leakage, so that anyone can easily perform a water leakage inspection in advance before actually raining or being exposed to strong wind and rain due to a typhoon.
