Bare concrete handrail combination overall-pouring one-step forming construction technology of pseudo-classic architecture

Abstract

The invention discloses a bare concrete handrail combination overall-pouring one-step forming construction technology of a pseudo-classic architecture. Small prefabs are manufactured firstly, then component templates of handrails and the small prefabs are combined and connected, so that necessary gaps are formed in concrete of the components from bottom to top, construction joint pouring is not needed, and the effect of bare concrete is achieved finally. According to the technology, overall combination pouring in place of the handrail of the pseudo-classic architecture and the effect of the bare concrete can be achieved, concrete cracks of the handrails are completely prevented, multiple technological innovations are achieved, and the bare concrete handrail combination overall-pouring one-step forming construction technology of the pseudo-classic architecture is formed in a summarized mode. Work efficiency is improved, appearance quality of the surface of the handrails is improved, so that integrality and durability of the handrails are improved, repairing and maintaining cost is greatly reduced, and the technology is a new practical technique which is economical, applicable and capable of being popularized.

Description

Technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a one-time forming construction process of concrete railings, in particular to a one-time forming construction process of an antique building fair-faced concrete railing combination integral casting. Background technique [0002] Antique railings, such as figure 1 As shown, it is generally composed of Dizhi 1, Wangzhu 2, Upright 3, Lower Crossbeam 4, Upper Crossbeam 5, Shengzi 6, Lotus Stigma 7, Huaban Wanzi Zao 8 (metallic material), it is an ancient building platform, gallery The common fence structures set up on the sides of roads, corridors, stairs and roofs have the important function of blocking and enclosing to prevent tourists from falling down. In ancient times, there were two forms of wooden railings and stone railings. With the application of concrete materials, the antique railings mostly use reinforced concrete structures instead of wooden structures, so t...

AI Technical Summary

Problems solved by technology

[0003] There are many components in the railing, and each component has a small cross-section. The shape of the lotus stigma and the riser is complex, and the construction of the concrete railing is difficult.

Traditional concrete antique railings are mostly constructed by prefabricated assembly, or cast-in-place spliced ​​and installed in sequence according to the construction sequence, that is, basement 1 → watch column 2 → column 3 → lower beam 4 → upper beam 5 → riser 6 → lotus column head 7 → Huaban Wanzizao 8 (metal material) is constructed sequentially, leaving many construction joints, and the joints are mostly treated with post-painting, which cannot achieve the effect of fair-faced concrete, and the joints are easy to crack. Every 5 to 6 months, the cracks will be different to varying degrees. Once again, the cracks need to be repaired every year, and the railings with paint, considering the color difference of the paint, the paint on the repaired part cannot be simply repainted, and the entire railing paint must be completely painted, which causes users to use it in subsequent maintenance. Maintenance costs during the period are always greater
