2. Description of the Related Art FIG. 5 is a diagram showing the installation of a spraying device disclosed in Japanese Patent Laid-Open No. 61-72169, and FIG. The equipment includes a cooling tank 1 for storing cooling water for lowering the temperature, a nozzle pipe 5 for spraying water from the cooling water tank onto a wall, a hose 3 for connecting the nozzle pipe 5, valves 2 and a drum 4 for winding the hose. Reference numeral 7 is concrete to which the exterior equipment 6 is closely attached, 8 is an infrared thermometer, and G is the ground.

Next, the operation will be described. Place the cooling water tank 1 on the roof of the concrete wall 7 that covers the exterior 6,
A hose 3 extends from the tank 1 through a valve 2 and is wound around a drum 4 attached to the tank, and then the other end hangs down.
The nozzle tube 5 is locked at the lower end. Operate the drum 4 to place the nozzle pipe 5 at a predetermined height position, and open the valve 2 to open the nozzle pipe 5.
Coolant water spouts from. In FIG. 6, the infrared thermometer 8 measures the temperature of the exterior.

[0004]

In the conventional device, it is necessary to install the cooling water tank on the roof, unloading of the cooling water tank, installation work, etc., and also for lateral movement of the nozzle pipe. It lacks convenience such as using ropes. There is also a problem that the equipment cost is too high because it needs a curing to prevent water damage to a third party.

The present invention was developed in order to solve the above problems, and an object of the present invention is to obtain a building exterior wall surface disbonding detection apparatus which is lightweight, convenient, and easy to install and use.

[0006]

The device according to the present invention comprises:
For forced cooling, a volatile liquefied gas enclosed in a pressure vessel installed above the ground is used, and a nozzle pipe guided from the pressure vessel is configured to move vertically and horizontally by a drum provided at the top of the building. Is.

Further, a pressure vessel for volatile liquefied gas and an infrared thermometer are mounted on a truck or a vehicle, and the ejection operation and temperature distribution of the volatile liquefied gas are measured while moving.

[0008]

When the volatile liquefied gas cylinder according to the present invention is installed on the ground, the volatile liquefied gas cylinder can be moved by a car or a trolley, which improves convenience. In addition, volatile gas does not require curing for dripping. Furthermore, since the drum is lightweight, the movable drum stand is inexpensive and easy to move and transport.

【Example】

Example 1. An embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, the movable drum base 11 is placed on the roof, and then the drum 12 is set on the base 11. Drum 12 to wire 13
Is wound and one end hangs down, the nozzle tube 14 is locked at the lower end, and a pressure resistant hose 15 is connected to the lower end of the nozzle tube.
When the drum 12 is operated to set the nozzle tube 14 at a desired height position and the valve 17 of the liquefied gas cylinder 16 is opened, a volatile liquefied gas such as carbon dioxide gas is ejected from the nozzle tube 14 to cool the surface equipment 6. Next, using the infrared thermometer 8 shown in FIG. 2, the temperature distribution is investigated in the same manner as in the conventional example shown in FIG. The position and left / right position of the nozzle tube 14 are adjusted by moving the movable drum base 11 on the roof.

Embodiment 2. In the case of the first embodiment, the liquefied gas cylinder 16 and the infrared thermometer 8 are shown installed on the ground, but these are mounted on a vehicle, and the volatile liquefied gas ejection operation and the temperature distribution measurement can be performed while moving. Is also possible.
An example will be described with reference to the drawings. In FIG. 3, a vehicle 10 is equipped with a liquefied gas cylinder 16 and an infrared thermometer 8. The infrared thermometer 8 is fixed toward the surface to be measured, and then a volatile gas is ejected. Next, the nozzle tube 16 is moved to measure the temperature distribution after cooling the surface to be measured using the infrared image analyzer 9. According to the specifications of the infrared thermometer 8, the measurement error of the temperature distribution becomes large at an angle of 45 degrees or more. In that case, the vehicle is moved to the measurable position and the same measurement is repeated.

In the above embodiment, the case where carbon dioxide gas is used as the volatile liquefied gas has been described, but nitrogen gas or argon gas may be used, and the same effect as that of the above embodiment can be obtained.

Embodiment 3. In the case of Example 1, the movable drum mount and the drum were installed on the roof, and the nozzle tube was attached to the wire wound around the drum. However, instead of the movable drum mount and the drum, an existing window cleaning gondola was used. It is also possible to use. An example will be described with reference to the drawings.
In Fig. 4, the nozzle pipe is attached to the upper handrail of the window cleaning gondola 20.
14 is fixed by the nozzle fixing belt 18. Then, while operating the gondola 20, the nozzle tube 14 is moved to the surface to be measured and measurement is performed.

[0013]

As described above, according to the present invention, the volatile liquefied gas enclosed in the pressure vessel installed on the ground is used for the forced cooling, and the nozzle pipe guided from the pressure vessel is built. Since it is configured to move up, down, left and right by the drum provided on the upper part, there is an effect that it is lightweight, convenient, and easily installed and used.

Further, it is more convenient if a pressure vessel for volatile liquefied gas and an infrared thermometer are mounted on a carriage or a vehicle, and the volatile liquefied gas is ejected and the temperature distribution is measured while moving. Will increase.
