Description

Downpipe structure combination

The invention relates to the technical field of building drainage pipe structures, in particular to a combination of downspout pipe structures.

Generally, water pipes are pre-buried in the cement floors of buildings, and the water pipes are used to provide the water on the ground and discharge it to the outside, so as to avoid the continuous expansion of the accumulation of water.

In addition, as shown in the ninth figure, the recent newer drainage construction method further prepares a groove 61 in the cement floor 60 around the upper end of the water pipe 70, and embeds a water collecting tray 80 in the groove 61, and the collecting The bottom of the water pan 80 is pre-fabricated with a drainage hole 81 with an assembly sleeve 811 before leaving the factory, so that the upper end hole of the water pipe 70 can be connected with the assembly sleeve 811, so that the water on the cement floor 60 can be further concentrated through the water collecting plate 80. It is then discharged to the outside through the water pipe 70 .

However, in the ninth figure, because the drain hole 81 with the assembling sleeve 811 at the bottom of the water pan 80 is processed before leaving the factory, go to the construction site with the cement worker in the groove 61 reserved with the cement floor 60 and the position where the water pipe 70 is buried It is not necessarily opposite; it is often necessary to modify the position of the groove 61 of the cement floor 60 during on-site construction, which causes many troubles in construction and delays the construction period.

For the water pan 80 as described above, even if the position of the water pipe 70 is checked during the on-site construction, and then the drainage hole 81 corresponding to the water pipe 70 is opened on site, but the drainage hole 81 cut on site can only form a simple circular hole, and cannot be further extended. As shown in Figure 10, since there is still a gap that is not connected between the upper end hole of the water pipe 70 and the drainage hole 81, it is impossible to prevent the use of drainage after installation and construction. Drainage can cause leakage from the outside of the water pipe 70 .

The main purpose of the present invention is to install a water collecting tray in a cement groove with a pre-embedded drain pipe, and open a drain hole corresponding to the position of the drain pipe during on-site construction to provide a combined downspout, so that the downspout can be connected with the drain pipe to form a drainage system.
