Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the leak detection device described in Patent Document 1 has the problem that it is time-consuming to assemble the discharge pipe to match the shape of the building being inspected, and that because the discharge pipe is assembled to match each building individually, a discharge pipe that has been used once cannot be used in other buildings. Furthermore, the watering method described in Patent Document 2 has the problem of requiring the effort of attaching the watering hose to the scaffolding and the effort of removing the watering hose when dismantling the scaffolding. This invention has been made in view of the above problems, and aims to provide a wall-mounted leak detection liquid spraying device that does not need to be assembled to match the shape of the building to be inspected, is easy to install for watering, and can be used repeatedly. [Means for solving the problem]

[0007] The invention made to solve the above problems is an inspection liquid spraying device used to spray an inspection liquid for rain leak testing on the wall surface of a building, characterized by comprising a spray pipe that is in the shape of a straight tube with both ends sealed and has a number of spray holes drilled in the pipe wall at predetermined intervals in the longitudinal direction, and an inspection liquid supply pipe that branches off from the middle of the spray pipe in the longitudinal direction.

[0008] In the inspection liquid spraying device of the present invention, the inspection liquid supply pipe branches off from the middle of the spray pipe in the longitudinal direction, so both ends of the spray pipe are freed from the inspection liquid supply pipe, making it easy to use both ends of the spray pipe when it is installed horizontally. In addition, the direction of the spray holes of the spray pipe can be adjusted by operating the inspection liquid supply pipe.

[0009] The test solution spraying device of the present invention preferably comprises a water hose for supplying tap water to the test solution supply pipe, and a test solution mixing device for mixing the test concentrate into the tap water flowing from the water hose to the test solution supply pipe. This allows the test concentrate to be directly mixed into the tap water flowing from the water tap, the test solution to be sprayed using the force of the tap water, and the test concentrate mixed into the tap water to be easily replaced.

[0010] The inspection liquid spraying device of the present invention preferably has a T-shaped joint in the watering pipe connected to the inspection liquid supply pipe, the T-shaped joint having an inlet portion extending perpendicular to the longitudinal direction of the watering pipe and connected to the inspection liquid supply pipe, and a joint body portion extending in the longitudinal direction of the watering pipe and having a pair of outlet portions at both ends, a pair of straight pipe portions detachably connected to the pair of outlet portions respectively, and a sealing member that detachably seals the ends of the pair of straight pipe portions. In this way, the T-shaped joint, the straight pipe portions and the sealing member can be disassembled and the inspection liquid spraying device can be carried without taking up much space.

[0011] Preferably, the main body of the T-shaped joint has sprinkler holes arranged along its longitudinal direction. This allows the inspection liquid to be sprayed continuously along the longitudinal direction of the sprinkler pipe.

[0012] Preferably, the sealing member is capable of detachably sealing the outlet portion of the T-joint. This allows the length of the sprinkler pipe to be shortened by omitting one or both of the straight pipe sections connected to both ends of the joint body of the T-joint and directly connecting the sealing member to the T-joint. [Effects of the Invention]

[0013] As described above, with the inspection liquid spraying device of the present invention, both ends of the spraying pipe can be used when the spraying pipe is placed horizontally, so the inspection liquid can be easily sprayed without having to fix it to scaffolding or the like. [Brief explanation of the drawing]

[0014] [Figure 1] This is a perspective view showing a rain leak inspection being performed using an inspection liquid spraying device according to one embodiment of the present invention. [Figure 2] Figure 1 is a front view of the test liquid spraying device. [Figure 3] Figure 1 is an exploded view of the test liquid spraying device. [Figure 4] This is a perspective view showing another method of using the test liquid spraying device shown in Figure 1. [Modes for carrying out the invention]

[0015] The embodiments of the present invention will be described in detail below with reference to the drawings as appropriate. However, the present invention is not limited to the embodiments described below, and modifications can be made as appropriate without departing from the spirit of the invention.

[0016] (Testing liquid spraying device) Figure 1 shows how a leak test is performed on building A using a leak test liquid spraying device 100 according to one embodiment of the present invention. The leak test liquid spraying device 100 is used to spray a leak test liquid B on the wall surface A1 of building A, and mainly comprises a straight sprinkler pipe 1 for spraying the leak test liquid B, and a leak test liquid supply pipe 2 that branches off in a T-shape from the middle of the sprinkler pipe 1 in the longitudinal direction and supplies the leak test liquid to the sprinkler pipe 1, as well as a leak test liquid mixing device 3 (see Figures 2 and 3) for introducing the leak test liquid into the leak test liquid supply pipe 2.

[0017] As shown in Figure 2, the sprinkler pipe 1 includes a T-shaped joint 11 located in the center of its longitudinal direction (left-right direction in Figure 2), a pair of left and right straight pipe sections 12, 12 extending from both ends of the T-shaped joint 11, and a pair of left and right sealing members 13, 13 that seal the ends 1b, 1b of the straight pipe sections 12, 12 (see Figure 3).

[0018] As shown in Figure 3, the T-joint 11 has an inlet portion 11a extending perpendicularly to the longitudinal direction of the sprinkler pipe 1 and a joint body portion 11c extending in the axial direction of the sprinkler pipe 1. The inlet portion 11a is connected to the inspection fluid supply pipe 2. Both ends of the joint body portion 11c are provided with a pair of outlet portions 11b, 11b, each consisting of a female screw hole. The peripheral wall of the joint body portion 11c is provided with numerous sprinkler holes 1a, 1a, ... that penetrate the peripheral wall in the thickness direction, arranged at predetermined intervals in the axial direction of the joint body portion 11c. In the illustrated example, the sprinkler holes 1a,1a,... are provided on the side of the joint body 11c (the front side in Figure 2), but the sprinkler holes 1a,1a,... may also be provided on the peripheral wall opposite to the inlet 11a of the joint body 11c (the upper side in Figure 2), or they may be provided to penetrate in any direction around the axis of the joint body 11c.

[0019] As shown in FIG. 3, the straight pipe portion 12 includes a straight pipe portion main body 121 composed of a straight pipe having a slightly smaller diameter than the joint main body portion 11c of the T-shaped joint 11, a male screw joint 122 adhered to the side of the straight pipe portion main body 121 on the T-shaped joint 11 side, and a female screw joint 123 adhered to the end portion on the side of the sealing member 13 on the opposite side. The straight pipe portion 12 is detachably connected to the outlet portion 11b formed by the female screw hole of the T-shaped joint 11 and the male screw portion 13a of the sealing member 13 described later. The male screw joint 122 is provided with a hexagonal portion 122a for rotation.

[0020] In the straight pipe portion 12, a large number of water spray holes 1a, 1a,... arranged in the longitudinal direction of the peripheral wall are linearly arranged. The water spray holes 1a, 1a... of the straight pipe portion 12 are provided so as to be substantially in a straight line with the water spray holes 1a, 1a,... of the T-shaped joint 11 in a state where the straight pipe portion 12 is completely screwed into the T-shaped joint 11.

[0021] As shown in FIG. 3, the sealing member 13 is composed of a short tube having substantially the same diameter as the joint main body portion 11c of the T-shaped joint 11, and the tip is sealed in a dome shape. The sealing member 13 is provided with a male screw portion 13a on the base end side, and a hexagonal portion 13b is provided adjacent to the tip end side thereof. The male screw portion 13a can be screwed into the female screw hole of the female screw joint 123, and can also be screwed into the female screw hole of the outlet portion 11b of the T-shaped joint 11. By directly connecting the sealing member 13 to the T-shaped joint 11 without the straight pipe portion 12, the water spray pipe 1 can be shortened.

[0022] Each part of the water spray pipe 1 is formed of a hard resin such as vinyl chloride.

[0023] In this embodiment, as shown in FIG. 3, the inspection liquid supply pipe 2 is composed of a flexible tube formed by providing a spiral groove on the outer periphery of a resin tube such as vinyl chloride so as to be bendable. The base end side is inserted into the inlet portion 11a of the T-shaped joint 11 and is adhesively fixed with an adhesive. A female screw joint 21 made of a hard resin such as vinyl chloride is adhesively fixed to the tip end side of the inspection liquid supply pipe 2, and a hose nipple joint 22 is further screwed into the female screw joint 21.

[0024] As shown in Figure 2, the test fluid mixing device 3 comprises a main pipe section 31 for supplying tap water to the test fluid supply pipe 2, a bottle section 32 branching off from the main pipe section 31 in a T-shape, a valve section 33 for opening and closing the connection between the main pipe section 31 and the bottle section, and an opening / closing knob 34 for opening and closing the valve section 33. The bottle section 32 is cup-shaped and made of a transparent container, and is configured to be detachably attached to the valve section 33 by screws when filled with the test concentrate L. By rotating the opening / closing knob 34, the test concentrate L in the bottle section 32 can be mixed into the tap water flowing through the main pipe section 31, adjusting the amount from zero to an appropriate level.

[0025] As shown in Figures 2 and 3, the test fluid mixing device 3 is connected to the water hose 6 via the distributor 5 on the upstream side (right side in Figures 2 and 3), and to the test fluid supply pipe 2 via the test fluid supply hose 4 on the downstream side.

[0026] The distributor 5 is equipped with four nozzles 5a on the downstream side for connecting a one-touch hose joint, and on the upstream side, it is equipped with a nozzle 5b for connecting to a water hose 6 via a union nut type joint, and four on / off knobs 5c for opening and closing the nozzles 5a.

[0027] (Method of dispensing test solution B) When spraying the inspection liquid B for leak detection onto the wall surface A1 of building A using the inspection liquid spraying device 100 having the above configuration, first, the inspection liquid spraying device 100, which has been disassembled as shown in Figure 3, is assembled as shown in Figure 2. As shown in Figure 3, the inspection liquid spraying device 100 can be easily assembled and disassembled without tools because each part can be connected by screws or one-touch joints, making it easy to transport when disassembled and allowing for repeated use.

[0028] The test solution spraying device 100 connects the water hose 6 to a water tap (not shown) with the valve section 33 of the test solution mixing device 3 closed. Before or after this, or in parallel, the bottle section 32 of the test solution mixing device 3 is filled with the test solution L of the desired color. The test solution L contains a fluorescent agent that emits red, blue, or yellow light when irradiated with ultraviolet light.

[0029] In parallel with, or before or after, connecting to the faucet and filling with the test concentrate L, the test liquid spraying device 100 is installed above the wall surface A1 to be inspected, with the spray holes 1a facing the wall surface A1, as shown in Figures 1 and 4. In the example in Figure 1, the wall surface A1 to be inspected is the exterior wall of building A, and in the example in Figure 4, it is the floor surface of the roof.

[0030] In the example shown in Figure 1, the inspection liquid spraying device 100 is installed by suspending both ends of the sprinkler pipe 1 from the fence A2 surrounding the rooftop using ropes R. In the example shown in Figure 4, the inspection liquid spraying device 100 is installed by resting both ends of the sprinkler pipe 1 on the fence A2, sandwiching the corner of the fence A2 on the rooftop.

[0031] Thus, in the inspection liquid spraying device 100, the inspection liquid supply pipe 2 branches off from the water spray pipe 1, allowing the inspection liquid spraying device 100 to be installed using both ends of the water spray pipe 1. Furthermore, since the water spray pipe 1 can be rotated using the inspection liquid supply pipe 2, the direction of the water spray holes 1a can be adjusted.

[0032] Once the connection to the water tap, filling with the test concentrate L, and installation of the sprinkler pipe 1 are complete, the water tap is opened, and the on / off knob 34 of the test liquid mixing device 3 is turned to mix an appropriate amount of test concentrate L into the tap water, while the test liquid B, consisting of a mixture of tap water and test concentrate L, is sprayed from the sprinkler holes 1a of the sprinkler pipe 1. Because the test liquid spraying device 100 is equipped with the test liquid mixing device 3 in this way, it is possible to easily mix the test concentrate L into the tap water and spray the test liquid B using the force of the tap water. In addition, the test concentrate L to be sprayed can be changed simply by replacing the bottle part 32.

[0033] When the width of the wall surface A1 to which the inspection liquid B is to be sprayed is narrow, one or both of the left and right straight pipe sections 12 are omitted and the sealing member 13 is directly connected to the outlet section 11b of the T-joint 11.

[0034] (Other embodiments) As described above, the test solution spraying device of the present invention is not limited to the embodiments described above, and may not include a water hose or a test solution mixing device. Alternatively, the test solution prepared by mixing tap water and the test concentrate beforehand may be stored in a bucket or the like and then drawn up and sprayed using a pump or the like. The spraying pipe may be formed as a single straight pipe, and the test solution supply pipe may be directly connected to this straight spraying pipe. Spraying holes do not need to be provided in the joint body of the T-joint. The sealing member does not need to be connectable to the T-joint. [Explanation of Symbols]
