Problems solved by technology

[0013] However, the known solutions of this type do not seem to be entirely satisfactory, especially with regard to the simplicity of construction and the assembly of accessories, as well as the overall effect of the drainage box
In fact, adding accessories to a drainage tank properly designed to provide some level of performance can change the efficiency of the drainage tank itself
[0014] Furthermore, the known attachments only enable the elevation of the drain tank to a preset height determined by the size of the attachment, and generally do not allow adjustment of the height of the drain tank

Embodiment Construction

[0024] exist figure 1 In , a drainage box is designated by 1, especially a drainage box forming part of a drainage system for the roof of a building. The system is not shown in its entirety and, as is well known, consists of a number of drainage tanks, usually mounted on the roof of a building, and pipes and collectors of various sizes and shapes that drain each The tank is connected to the mains for discharge to the outside of the building.

[0025] The drainage tank 1 extends substantially along an axis A (in use, said axis is substantially vertical) and mainly comprises a base body 2 having an opening 3 serving as a water inlet, said opening being formed with a The pipes 4 communicate within the base body 2 ; and the cover 5 is arranged above the base body 2 and provided with a top grid 6 .

[0026] In the example shown, but not necessarily, the drainage box 1 is a siphon effect drainage box.

[0027] The base body 2 is a substantially tubular body formed as a whole like...

Abstract

An overflow device (25) for water drain assemblies, in particular for drainage systems for roofs of buildings, comprises a removable overflow accessory component (30), which extends substantially along an axis (A) and which can be installed on a water drain assembly (1) for varying the level of water entering the drain assembly (1); the component (30) comprises a lower element (31) and an upper element (32), which are telescopically coupled together along the axis (A), and a height-adjustment device (33) for varying the position of the elements (31,32) with respect to one another along the axis (A), and consequently the axial height of the component (30).

Description

technical field [0001] The present invention relates to an overflow device for a drainage tank, in particular a drainage tank for a drainage system on the roof of a building, and to a drainage tank provided with said overflow device, in particular for use in The drainage tank of the drainage system on the roof of the building. Background technique [0002] Typically, a drainage system for building roofs for the drainage of rainwater consists of a collection drainage tank and a network of pipes. [0003] Typically, drainage systems are sized according to the amount of rainfall expected in the area in which they are installed. However, one contingency is to install an emergency system next to the main system, which has a function of preventing the building roof from being overburdened if the rainfall is larger than expected. [0004] Emergency systems can be obtained in various ways, such as: [0005] - by perforating holes in the parapets delimiting the roof of the buildin...
