Problems solved by technology

Although the rigid formwork used (mainly wood formwork, or bamboo formwork, or steel formwork, or aluminum alloy formwork or reinforced plastic formwork) can be used repeatedly, the process of formwork installation and formwork removal is complicated and the safety is poor. The accuracy of the size and shape of the concrete is poorly guaranteed, and the labor cost is high. What makes the construction party and the construction party a headache is the long construction period, because the strength maintenance time required for ordinary concrete pouring to formwork removal usually takes about one week or even longer. Seriously affect the progress of the project; secondly, because the distance between the enclosure formwork and the steel bars in the formwork frame is difficult to be determined in a balanced manner or the formwork frame

Abstract

The invention relates to a protective rib template for a cast-in-place reinforced concrete beam column. The protective rib template mainly comprises a rigid fiber mortar rib template and a connectingcomponent, wherein the rigid fiber mortar rib template is prepared from cement mortar or fiber cement mortar, or is prepared by transversely and/or longitudinally distributing fiber ropes into the cement mortar or the fiber cement mortar, or is prepared from the cement mortar, or the fiber cement mortar and fiber cloth and/or a filter net or is prepared from the cement mortar, or the fiber cementmortar and fiber cloth and/or a filter net and/or the fiber ropes. The protective rib template has the characteristics that the cracking resistance and the shock strength are high, the structure is simple, the mass is light, the template can resist construction collision, and the evaporation of the moisture of newly casted concrete slurry can be prevented; form removal is not required, so that theconstruction progress is accelerated, the construction quality is improved, and a main steel bar in the reinforced concrete is provided with a concrete protecting layer with a thickness which is notlower than 25mm; and the protective rib template can be individually and accurately customized.

Description

technical field [0001] The invention relates to a protective rib formwork, in particular to a cast-in-place reinforced concrete beam-column protective rib formwork for beam / column pouring in construction engineering. Background technique [0002] At present, cast-in-place reinforced concrete beam-column structures are popularly used in construction projects. The basic procedures include erecting frames, installing steel bars, setting rigid formwork according to the size and shape of beams or columns, forming formwork frames, adding hoops for fastening, and then pouring The concrete slurry is compacted, and the formwork is removed after the concrete has completely solidified and hardened. Although the rigid formwork used (mainly wood formwork, or bamboo formwork, or steel formwork, or aluminum alloy formwork or reinforced plastic formwork) can be used repeatedly, the process of formwork installation and formwork removal is complicated and the safety is poor. The accuracy of ...
