Abstract

Drip tray, characterized in that it is an angle rail with perforation, which has two bends.

Description

State of the art:

• • Insect screens or ventilation angle, hinder the penetration of insects under the roof, hinder also the drainage of condensation.
• • In addition a drip tray is required that condenses at least 15 mm away from the timber formwork.
• • If the drip tray is installed, an insect screen can not be attached to the timber formwork.
• • If a ventilation angle is screwed on the drip tray, water can not drain, because the vents above the drainage level lie.
• • Of the Workload is high because two elements are assembled.

Problem:

• • The usual Components are difficult to combine with each other.
• • Either the ventilation element can not be fixed properly (insect screen) or
• • The ventilation element hinders drainage of condensed water (ventilation angle).
• • The newly developed "drip tray with bird protection "signs out, giving it five tasks links:
• • opening to ventilation the roof skin
• • Exit for condensation under the roof skin
• • Optical appealing completion of the ventilation level, without wave formation.
• • Defense of birds and insects
• • Drip tray according to roofer guideline

This is it Sheet folded at certain angles, so formed a drip edge is punched and defined, allowing water through the holes, the are in a bend, can run off. It is only one component too assemble.

"Drip tray with bird protection" is characterized by the execution:
In order to reach the 15 mm projection as a drip edge and still lie flat against the roof batten, the angle ( 4 ) be folded over 90 ° and requires a Gegenkantung ( 3 ) at the level of the roof lath lower edge.

The mounting thigh ( 1 ) rests on the eaves formwork. He stands 15 mm ( 5 ) over the formwork ( 7 ) over (drip edge)

The visible fan thigh ( 2 ) lies flat on the batten ( 10 ) at.

The visible thigh ( 2 ) of the angle is completely perforated to obtain the maximum ventilation cross section.

The inner row of holes is located in the center of the kink ( 4 ). This ensures drainage of the condensate.

In the mounting leg ( 1 ) are located on two axes offset holes for fasteners.

mounting:

The drip tray with bird protection can be screwed onto the formwork with self-tapping screws or roofing pins in screw holes ( 7 ) or from the front of the batten ( 10 ).

Installation sequence:

• 1. Drip tray with bird protection ( 11 ) on the formwork ( 7 ).
• 2. Underlay membrane ( 8th ) in the bird screen ( 11 ) (holes in the kink must remain free)
• 3. counter battens ( 9 nailing)
• 4. batten ( 10 ) with the eaves formwork ( 7 ) flush on the counter battens ( 9 ).
• 5. Drip tray with bird protection ( 11 ) on batten ( 10 ).

Achieved benefits

• - Instead of of the conventional Drip tray becomes the "drip tray with bird protection "15 mm protruding attached to the formwork. It is only one step necessary. The installation of an additional Protective element such as ventilation angle or insect screen is omitted.
• - To Attachment are holes pre-cut in two axes. The staggered attachment is the Drip tray tight on the formwork without tilting. It can not Groove between eaves mold and drip tray with bird protection emerge, the viewed from below would be a black line.
• - The sarking membrane lies in the drip tray with bird protection, so the water that is on the sarking membrane ( 8th ), is passed into the drip tray. The water can escape from the drip plate formed as an angle, because the axis of the lowest row of holes with the edging ( 4 ) is congruent and thus at the lowest point of the cross section. Since the underlay at the gutter formwork is cut flush, the drainage holes in the 15 mm ( 5 ) protruding drip tray are not obscured. The dripping water drops freely without wooden shuttering ( 7 ) or wooden rafters ( 8th ) to wet.
• - The counterbending ( 3 ) gives the fan leg ( 2 ) Stability. The typical for ventilation grills wave formation is avoided. The Gegenkantung is carried out so that the upper part of the fan leg ( 2 ) flat against the roof batten, whereby the screwing or nailing to the batten is possible.
• - The expensive Traufkeilbohle can by cheaper rectangular slats ( 10 ), because the underlay ( 8th ) not from the eaves formwork ( 7 ) must be led to the gutter inlet. The construction described also works even with very flat roof pitches, where the Traufkeilbohle formed by negative slope in the underlay a gutter.
