Description

(54) HYDRAULIC ROOF WATER DETECTOR

 The invention relates to land construction and can be used in the construction of buildings having a non-roll roof with internal drainage. The known drainage unit of a roll-free roof, which includes supporting the panels in the middle of the building on an assembly run consisting of two beams, between which is a drain funnel 1. The disadvantages of this node are the unreliability of the seal at the junction of the panels with the assembly run, the need to install two beams, installation, and the difficulty of replacing or repairing a funnel drain. The most LOW-free solution is the known node of a roll-free roof, including a support part in the form of two beams, catchment chutes with end ribs and a funnel 2 supported on it. The disadvantages of the known drain unit are the need to install an internal drain funnel in each catchment tray, complexity installation And; operation, as well as the need to install (mount) the two support blocks (lining beams), as the edges of the trays and the gap between them, DO NOT allow one support block, which should have a cutout in the upper part for the internal drain funnel. The aim of the invention is to simplify installation and improve performance. This goal is achieved by the fact that in a water-free node of a roll-free roof, including a support part, supported on it. Extension trays with end ribs and a funnel of internal drainage, the support part is made with a cutout to accommodate the funnel, and the end ribs of the catchment trays are made C-shaped in plan and included in the contour of the funnel. FIG. 1 shows the layout of the interface; in fig. 2 -. Section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1. A drainage assembly of a non-roll roof includes drainage trays 1, which rest on supporting part 2. Under the joint of catchment trays 1 there is a funnel of the internal drain 3, and a grate is installed above the joint of the drain 4. Support part 2 has a cutout 5 under the funnel of internal drain 3

and columns 6, on which the ends of the longitudinal edges of the drainage chutes 1 are supported. The catchment chutes 1 have at their ends drainage ribs 7 included in the contour of the funnel 3.

The construction of catchment trays 1 with spillway drainage ribs 7, which are C-shaped in plan, as well as the presence of support part 2 as a block with a cutout for funnel 5 with columns 6 under the joints of longitudinal edges of catchment trays 1, simplifies the design and installation of this drain unit and reduces the number of support blocks 2 and internal drainage funnels 3 is 2 times, since the G-shaped drain edges 7 of the two catchment trays 1 are included in the contour of the common funnel 3 of the internal drainage, and the single support block 2 has a notch 5 for placement Funnels 3 and common columns 6, located under the columns of the longitudinal edges of the catchment trays 1.

The estimated economic effect from the implementation of the invention is the saving of one support block and one funnel.

per node and is about 100 rubles and 10 man-hours.
