Background
The inclined roof has the characteristics of attractive appearance and attractive visual perception, can increase the using space of the building, is favored by architects, and is widely used in civil buildings. From the construction perspective, the inclined roof is difficult to construct, the quality control difficulty is high during concrete pouring, the concrete is easy to flow and difficult to form when the slump is high, and the concrete is difficult to vibrate and compact when the slump is low; the concrete forming flatness of the inclined roof surface is poor, and the thickness of a designed leveling layer is difficult to meet the requirement, so that the thickness of the mortar is too large during leveling, and a large amount of mortar is wasted; the sloping roof has more detail nodes, and compared with a flat roof, the sloping roof is more easy to have quality defects such as leakage and the like. Therefore, the industry has proposed various solutions to solve the problem and has contributed much.
Chinese patent CN109296202A discloses a method for pouring concrete on a steep slope roof and a formwork system in 2019, 2.1.2019, wherein the construction of the inner formwork of the steep slope roof is performed to bind the roof reinforcing steel bars of the steep slope roof; welding a plurality of rows of supporting steel bars on the roof steel bars of the large-gradient inclined roof, enabling the supporting steel bars to be perpendicular to the large-gradient inclined roof, arranging a blocking plate, enabling the blocking plate to stretch across the supporting steel bars in the same row, and enabling the bottom of the blocking plate to be parallel to the inner template; and (5) pouring concrete in sections from bottom to top by taking the barrier plate as a boundary. The formwork system comprises an inner formwork, a plurality of rows of supporting steel bars welded on the roof steel bars and blocking plates fixed on the supporting steel bars. According to the technical scheme, a single-side formwork supporting process is adopted, although the supporting of an outer formwork is omitted, the supporting steel bars are perpendicular to the large-gradient inclined roof, and a large number of blocking plates are used for assisting, so that the time and labor are still wasted when the sectional pouring process of the inclined roof is implemented, and the high-quality and rapid construction target is difficult to achieve.
Chinese patent CN106437142A discloses a cast-in-place sloping roof double-layer formwork structure and a sloping roof construction method in 2017, 2.22.2017, wherein the double-layer formwork structure comprises a support rod system, a formwork keel, a bottom formwork, a surface formwork and a split positioning water stop bolt; the bottom of the template keel is supported and fixed by a support rod system; the bottom layer formwork is laid on the upper surface of the formwork keel, the surface layer formwork and the bottom layer formwork are arranged in parallel, and the distance between the surface layer formwork and the bottom layer formwork is equal to the thickness of the slope roof concrete pouring layer; the bottom layer template and the surface layer template are positioned by the split positioning water stop bolt; the surface layer formwork is composed of a plurality of segmented surface layer formworks arranged at intervals, and a groove body formed between the end part of each adjacent segmented surface layer formwork and the bottom layer formwork is used as a vibrating groove in concrete segmented pouring. The technical scheme of the invention adopts a double-layer template structure, and although a plurality of vibrating grooves are arranged, the concrete is difficult to vibrate and is not easy to pour compactly, and the defect of compactness of the concrete structure exists. Then the concrete is poured according to the layer by section, and cold seams are generated in the overlapping area of the concrete to hinder the construction quality. In addition, concrete flows along the sloping roof when vibrated, is difficult to form and has high vibration difficulty. The concrete molding is not compact, which causes quality defects such as honeycomb pitted surface, holes and the like, seriously influences the engineering quality of the sloping roof and has leakage hidden trouble in the later period.
The known method for erecting a concrete pouring formwork for a sloping roof therefore has the inconveniences and problems mentioned above.
