Natural ventilation adjusting system for planted roof and construction method thereof

Abstract

The invention discloses a natural ventilation adjusting system for a planted roof and a construction method thereof. The natural ventilation adjusting system comprises a first waterproof layer covering the upper surface of a roof structure, a plurality of ventilation well mechanisms are arranged on the first waterproof layer, and ventilation plates are further fixed to the upper surface of the first waterproof layer. Every two adjacent ventilation wells communicate with each other through the corresponding ventilation plate, heat-insulating plates which are in butt joint with the side edges ofthe ventilation plates are further fixed to the first waterproof layer, and the ventilation plates and the heat-insulating plates are located on the same plane. The upper surfaces of the ventilationplates and the heat-insulating plates are both covered with light aggregate slope making layers, and the upper surfaces of the light aggregate slope making layers are covered with a second waterprooflayer. The problems that as for an ultra-large-area planted roof, a large quantity of ventilation pipes extending out of a vegetation layer damages the overall beauty of the planted roof, the roof structure layers are many, the work procedures are complex, the ventilation pipes are extremely prone to being plugged in the construction process, and thus waterproof coiled materials are cracked and damaged due to lower accumulated water freezing expansion, overlarge air pressure and the like are solved.

Description

Technical field [0001] The invention relates to the field of building construction, in particular to a natural ventilation adjustment system for planting roofs and a construction method thereof. Background technique [0002] According to the requirements of "Technical Specifications for Roofing Engineering" GB50345-2012 and "Flat Roof Building Construction" 12J201: "When it is difficult to dry the insulation layer of the concrete structure roof, ventilation measures should be taken. The vertical and horizontal spacing of the ventilation channels should be 6m, and the roof area should be 36 square meters. Set up a vent pipe, the vent pipe should be firmly fixed and waterproof treatment", common roof ventilation method is arranged in a plum blossom pattern The ventilation pipe is installed and fixed after the waterproof construction of the bottom layer of the roof is completed; this will not only easily damage the bottom waterproof, but also bring great inconvenience to the subsequ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a natural ventilation regulating system and construction method for planting roofs, which solves the problem that for super-large-area planting roofs, a large number of ventilation pipes protruding from the vegetation layer not only destroy the overall aesthetic feeling of the planting roof, but also the structural layer of the roof Many, complicated procedures, and the ventilation pipe is easily blocked during the construction process, resulting in the cracking and damage of the waterproof membrane due to the accumulation of water in the lower part, frost heaving, excessive air pressure, etc.
