As an improvement of the technical scheme, the oval PVC gas collection flow guide pipe and the exhaust pipe are both
The PVC gas collection and guide pipe is cut into 1/4 pipe diameter, and the rest 3/4 arch is reversely buckled for use.
As an improvement of the technical scheme, the veneer anti-skid floor tile is adhered by adopting a professional adhesive or mortar.
As an improvement of the technical scheme, the slope of the reinforced concrete roof needs to be optimized in advance during pouring construction, and the slope is finely adjusted after the waterproof mortar is leveled to the protective layer, so that leaked water stains or condensed water generated by temperature difference in the heat-insulating layer can be timely removed under the condition of multiple waterproof design failure.
As an improvement of the technical scheme, after the thinnest 30-thick LC5.0 light aggregate concrete is poured, water is applied for maintenance for more than 7d the next day, and people are not allowed to enter the maintenance period or the next construction is carried out.
As the improvement of the technical scheme, after the veneer anti-skid floor tile is laid, water is applied for maintenance for more than 3d on the next day, people are not allowed in 3d, the unqualified floor tile is repaired after 3d, whether the unqualified floor tile has the unqualified phenomena of hollowing, fracture and the like is checked, and pointing is carried out after all the floor tiles are qualified.
As the improvement of the technical scheme, all the pipe ditches and pipe orifices on the roof decoration layer need to be cleaned regularly by a specially-assigned person, so that accumulated water is prevented from being blocked.
After the technical scheme is adopted, the inverted type hidden structure of the hidden exhaust pipeline of the roof with the manned face bricks and the construction method thereof at least have the following advantages:
1. the technical scheme is a sandwich biscuit type method, two layers of durability, high temperature resistance and extensibility on the board surface are combined together, and the heat insulation layer has higher pertinence and guarantee compared with the construction quality of a related atlas, the hierarchical design and the arrangement of each functional structure are more scientific and reasonable, the working procedures are rigorous, the construction is simple, the operation is convenient, and the comprehensive cost is low.
2. The engineering quality is safer and more reliable, the waterproof layer is directly arranged on the concrete structure surface with optimized slope adjustment, the waterproof combination is better, the extension, extension and contraction sealing effects are good, the single exhaust drainage floor drain is added, and the waterproof quality is more guaranteed; meanwhile, gas in the leveling layer and the heat insulation layer can be discharged in time, and the roof is effectively prevented from cracking and damaging due to frost heaving of condensed water and pressure of the gas.
3. The requirements of building energy-saving parameters are ensured, and simultaneously, the waterproof quality of the roof and the durability of materials at each functional level are effectively solved and ensured, so that the materials at each functional level form the optimal organic combination, and the optimal material functions are exerted to the maximum extent.
4. The problem of common quality is effectively solved or reduced, the service life of the roof is prolonged, reworking maintenance is almost avoided, the comprehensive construction cost is low, the arrangement of the pipelines and the pipeline decoration pier seats is accurate, the height is uniform, and the good impression effect is achieved.
5. The multifunctional layer slope adjusting and inverted waterproof construction is adopted, and the diversion air-entraining pipes, the exhaust holes and the invisible floor drain are reasonably arranged so as to timely remove water stains on the decorative layer and water vapor in the leveling layer and the heat insulation layer. The method is widely applied to the subsection construction of the roof, can ensure that water stain on a decorative layer and water vapor in a slope finding layer of the roof are timely discharged, cannot largely leak below a concrete hardened layer, and can ensure that the roof does not leak through multiple measures such as inversion construction and adoption of non-cured rubber asphalt, combination of high polymer coiled materials, fine mortar slope adjustment, flow guide air guide pipes, exhaust holes, invisible floor drains and the like in case of leakage.
PVC gas collection honeycomb duct cut open pipe diameter 1/4 tubular product, with the use of remaining 3/4 arch left-hand thread, the atress is better, and the space is bigger, avoids traditional drilling parcel to cause simultaneously that the alkali solidifies the sclerosis and blocks up the passageway to can not make the moisture content under the rigid concrete sclerosis layer can not go out because of high temperature evaporation, with roofing decorative layer jack-up, destroy the decorative layer.
7. The waterproof layer, the screed-coat, the heat preservation, it is unobstructed not blockked up that the intraformational gas of decoration exhausts for a longer time, simultaneously can be with the water stain and the heat preservation of the construction layer seepage more than the partial heat preservation in time water conservancy diversion fast because of the comdenstion water that the temperature difference produced, through the blast pipe of secretly burying in advance, the floor drain is discharged, prevent because of expend with heat and contract with cold, gaseous pressure leads to the decorative layer fracture, it is low to synthesize construction cost, each item functional quality is secure, roofing life extension, the pipe arrangement is pleasing to the eye not account for the space, the overall arrangement highly.
