It has a flat tip with a wide width in the direction perpendicular to the paper surface of . As will be described later, the molten asphalt that has been pressure-fed to the heat-retaining flexible hose 14 has its flow rate reduced by this construction nozzle 10 and spreads and expels in an advantageous manner for spraying on the rooftop 2.

Further, as shown in FIG. 1, the cleaning automatic valve 24 is provided with a hose connection port 22.
The nozzle joint 12 at the tip of the heat insulation flexible hose 14 is fitted into the hose connection port 22 with the construction nozzle 10 removed. By connecting the heat-insulating flexible hose 14 to the automatic cleaning valve 24 as described above, the asphalt transfer passage centering on the plurality of transfer pipes 30 and the cleaning centering on the plurality of cleaning pipes 28 A passage is formed so as to circulate with the passage. By circulating the cleaning liquid (kerosene) 62 through this circulation passage, as will be described later,
The asphalt remaining in the transport pipe 30 is washed and removed.

Now, a procedure of asphalt waterproofing using the asphalt waterproofing apparatus 1 having the above-mentioned structure will be described with reference to FIGS. First, an asphalt melting pot 42, a cleaning liquid tank 60, a pump base 58, and an asphalt pump 50 are installed on the ground surface 6 on the side of the building 4 on which asphalt waterproofing is to be performed. Then, the cleaning liquid recovery pipe 29 and the drain valve 3
8, the pipe 39 for pressure feeding, the drain pipe 40, and the cleaning liquid supply pipe 46 are connected to each other. Next, the pipe laying member 32 is attached to the side wall 4a of each floor of the building 4. Then, the transfer pipes 30 are connected to each other and extended upward by the procedure described above. At this time, the assembled transport pipe joint 36 is fixed to the pipe laying member 32. Further, as shown in FIG. 2, the plugs 82 of the respective transport pipes 30 are respectively connected to the sockets 84 of the transport pipes 30 above them. And
A power supply cord is connected from a power source (not shown) to the socket 84 of the lowermost transfer pipe 30 to heat the band heaters 78 to 78 of all the transfer pipes 30 to 30 and 30A.

Similarly, the cleaning pipes 28 are also connected to each other and laid along the side wall 4a of the building 4 to the rooftop 2. The transfer pipe 30 and the cleaning pipe 28 extended to the roof 2 respectively include a transfer automatic valve 18, a flexible hose 14, a nozzle joint 12, a construction nozzle 10, and a cleaning automatic valve 2.
4 are connected to assemble the asphalt waterproofing apparatus 1 shown in FIG.

When the asphalt waterproofing apparatus 1 is assembled in this manner, first, the two automatic valves 18 and 24 on the rooftop are closed, and the drain valve 38 is also closed. The three-way valve 44 is used for the asphalt melting pot 4
2 and the asphalt pressure feeding pump 50 are communicated with each other, and the cleaning liquid supply pipe 46 side is closed. In this state, the asphalt raw material is put into the asphalt melting pot 42, the oil burner 48 is ignited, and molten asphalt is produced. After the molten asphalt in the asphalt melting pot 42 reaches a predetermined amount and temperature, the pressure pump motor 56 is driven, and the asphalt pressure pump 50 operates. As a result, the molten asphalt is pumped up from the asphalt melting pot 42 and conveyed to the roof 2 through the pressure-feeding pipe 39 and the conveying pipes 30 to 30 and 30A .

On the other hand, near the construction nozzle 10 at the tip of the flexible hose 14 attached to the rooftop 2, an operator having a dedicated transmitter for the automatic valves 18 and 24 stands by. Then, after the asphalt pressure feeding pump 50 is activated, the transfer valve control unit 20 is operated by the dedicated transmitter to open the transfer automatic valve 18. As a result, the molten asphalt that has been pressure-fed passes through the flexible hose 14 and is discharged from the construction nozzle 10. The worker holds the construction nozzle 10 and sequentially moves the roof top surface 2 to uniformly spray the molten asphalt. To adjust the amount of molten asphalt sprayed, the transfer valve control unit 20 is remotely operated to transfer the automatic transfer valve 18.
This is done by changing the opening degree of. Further, the operator can close the automatic transfer valve 18 as necessary to interrupt the spraying of the molten asphalt. In this way, asphalt waterproofing is performed by spraying the molten asphalt on the roof top surface 2.

Next, when the asphalt waterproofing apparatus 1 is withdrawn after the construction is completed, or when the asphalt waterproofing operation is suspended for a long time such as at the end of the work for one day in the case of several days, it is used for transportation. The asphalt remaining in the pipes 30 to 30 and 30A is washed and removed. Regarding the method of cleaning this residual asphalt, FIG. 1 and FIG.
Will be described with reference to. First, after stopping the asphalt pump 50, the drain valve 38 is opened,
The construction nozzle 10 is removed from the nozzle joint 12, and the automatic transfer valve 18 is also opened. As a result, most of the molten asphalt in the upright conveying pipes 30 to 30 and 30A falls free, passes through the drain pipe 40, and returns to the asphalt melting pot 42.

Next, the drain valve 38 is closed and the three-way valve 44 is switched to the cleaning liquid supply pipe 46 side. On the other hand, the tip of the nozzle joint 12 on the roof 2 is fitted and fixed to the hose connection port 22. Then, the automatic cleaning valve 24 is opened together with the automatic transfer valve 18, and the asphalt pump 50 is operated. As a result, the cleaning liquid (kerosene) 62 is pumped up from the cleaning liquid tank 60, passes through the cleaning liquid supply pipe 46, the pressure feeding pipe 39, and the transport pipes 30 to 30 , 30A ,
Furthermore, a flexible hose 14, a cleaning pipe 28A,
After passing through 28 to 28 , it is returned from the cleaning liquid recovery pipe 29 to the cleaning liquid tank 60. By circulating the kerosene 62 in this manner, the transport pipes 30 to 30, 30
The molten asphalt remaining on the inner wall of A is washed and removed. As a result, the asphalt waterproofing construction device 1 can be easily withdrawn after the construction is completed, and even if the work is interrupted for a long time, the asphalt remaining in the transport pipe 30 is solidified and the transport is hindered. Without it, work can be resumed smoothly.

In the above embodiment, the cleaning pipe 2
8. The length / thickness of the transfer pipe 30, the thickness of the pipe heat insulating material cover 68, the shapes of the pipe joints 34, 36, etc. are merely examples, and various sizes and shapes other than these can be used. .
