Roof structure for energy-saving building with rainwater collection and utilization

Abstract

The invention discloses a roof structure for an energy-saving building with rainwater collection and utilization. The roof structure for the energy-saving building with the rainwater collection and utilization comprises a first supporting steel bar, shear support frames, a third supporting steel bar and a second waterproof layer, the shear support frame is fixed to the upper part of the first supporting steel bar through screws, and second supporting steel bars are mounted at the top ends of the shear support frames through screws and welded and fixed to the left side and the right side of thethird supporting steel bar; and purlins are fixed to the upper parts of the second supporting steel bars through screws, a first pouring formwork is poured and fixed to the upper parts of the purlins, second pouring formworks are poured and fixed to the left side and the right side of the first pouring formwork, and the bottom ends of the second pouring formwork are connected with the first supporting steel bar through reinforcing bars. The second pouring formwork is installed on the roof structure for the energy-saving building with the rainwater collection and utilization, a concrete layerarranged in an inclined mode and a guide baffle are conveniently matched to dredge rainwater into water storage chambers of the second pouring formworks, and water of the water storage chambers can beused for watering flowers.

Description

technical field [0001] The invention relates to the technical field of energy-saving buildings, in particular to an energy-saving building roof structure that can collect and utilize rainwater. Background technique [0002] Energy-saving buildings refer to the combination of energy-saving concepts in the process of building construction, so that buildings can save resources to the greatest extent and protect the environment, thereby improving human living standards. Our common roof is a kind of building. The type of roof There are many, including flat roofs, sloping roofs, arched roofs and spherical roofs, etc. The most common ones are flat roofs and sloping roofs. Although there are many types of roofs, there are still some shortcomings, such as: [0003] 1. The patent published by the announcement number "CN109235786A" is "a new type of simple building roof with good lighting", which solves the problem that most of the traditional building roofs have no water collection fu...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an energy-saving building roof structure that can collect and utilize rainwater, so as to solve the above-mentioned background technology. The traditional building roofs on the market do not have a filter mechanism when collecting rainwater from hell, and the filter mechanism is fixed installation. , the problem of clogging will occur after long-term use. Most of the traditional building roof structures are insulated by heat insulation materials, and the heat insulation effect is poor.
