Structure for controlling seepage in roof skylight construction and construction method

Abstract

The invention discloses a structure for controlling seepage in roof skylight construction and a construction method. Firstly, within 10-20 cm around a roof skylight, thermal insulation layers, water-proofing layers and surface protecting layers of a roof board are chiselled away till base layers are exposed; the base layers are roughened; the base layers are cleanedand brushed with cement-based permeable crystals; steel bars are implanted in the roof board at the sectionposition where the chiselling is conducted, and distribution steel bars are arranged; then, early-strength impermeable concretewhich is used by manually throwing is adopted to fill the roof board, the filling thickness is 10-12 cm, a slope is adopted to cover the top of the concrete, a post-pouring belt of which the width is no less than 10 cm is reserved at the position where new materials and old materials of the roof board are combined; water-swelling rubber water-proof strips are stuck onthe surfaces corresponding to the upper and lower sides, avoiding the steel bars, of the post-pouring belt; after the final setting of the concrete, bridging particles are used to fill the post-pouring belt; finally, capping material are adopted to conduct capping. The structure and the method have the advantages of being reasonable in design, low in cost, convenient to construct and operate, long in service life and high in construction safety, having structural reinforcement, saving resources and reducing seepage risks, and effectively solve the seepage problem in current roof skylights.

Description

technical field [0001] The invention relates to the technical field of building waterproofing and leak repairing, in particular to a roof skylight structure leakage control structure and a construction method. Background technique [0002] At present, most of the roof skylights use parallel skylights. The joint of the edge of the roof skylight is a major difficulty in waterproof construction. In recent years, the problem of leakage around the roof skylight has been serious. Leak-proof construction. The roof skylight must be very careful during the construction process. If there is a construction error, it will easily cause leakage. The current construction management is difficult to meet the requirements; at the same time, after being put into use, due to the influence of temperature changes, material durability and other factors, All will cause cracking at the joints, resulting in leakage; and the leakage control of roof skylights has always been a problem that is difficul...

The roof skylight must be very careful during the construction process. If there is a construction error, it will easily cause leakage. The current construction management is difficult to meet the requirements; at the same time, after being put into use, due to the influence of temperature changes, material durability and other factors, It will cause cracks at the joints, resulting in leakage; and the leakage control of roof skylights has always been a problem that is difficult to solve completely in the project
