Problems solved by technology

The rigid formwork used includes wood formwork, bamboo formwork, steel formwork, aluminum alloy formwork or reinforced plastic formwork. Although it can be used repeatedly, the process of formwork installation and formwork removal is complicated, time-consuming and labor-intensive, and the labor cost is high.
What makes the project builder and construction party more troublesome is the long construction period, because the strength curing time required for ordinary concrete pouring to form removal generally takes about one week or even longer, which seriously affects the progress of the project; secondly, because the enclosure formwork and formwork It is difficult to determine the position and distance of the steel bars in the frame evenly, or the formwork frame slips and grout leaks during pouring vibration, which makes the standard that the concrete protective layer of the steel bars required by the standard not less than 25-30mm cannot be guaranteed, and even exposed bars appear, affecting The durability of the reinforced concrete structure; moreover, the concrete after the formwork is removed still needs to be watered regularly every day or covered with a film to moisturize and maintain for a period of time, otherwise, the strength may be too poor or cracked and scrapped due to dehydration and burnout
In addition, the concrete after formwork removal is not yet fully hydrated, and its strength is low, and it is easy to be partially damaged due to collisions during construction and has to be repaired.

Abstract

A protective reinforced rib template for construction mainly comprises a rigid fiber mortar reinforced rib template body, the rigid fiber mortar reinforced rib template body comprises a rib plate anda rib strip. The rib strip is fixed to the inner plate face of the rib plate, the rib plate and the rib strip are prepared from cement mortar or fiber cement mortar, or prepared from that rib ropes transversely and / or longitudinally arranged in the cement mortar or the fiber cement mortar at intervals, or prepared from the cement mortar or the fiber cement mortar and fiber cloth and / or fiber meshes, or prepared from the cement mortar or the fiber cement mortar and the fiber cloth and / or the fiber meshes and / or fiber ropes. The protective reinforced rib template for construction has theadvantages of being low in weight, high in anti-cracking and anti-impact strength, simple in structure, convenient to manufacture, convenient to transport, low in cost, economical and practicable andthe like. Form removing is not needed, acceleration of the construction schedule is facilitated, and the construction quality is improved. Evaporating of moisture in cast-in-place concrete slurry canbe prevented, and the protective reinforced rib template can be individually and accurately customized, and is convenient to construct and install.

Description

technical field [0001] The invention relates to a ribbed formwork, in particular to a protective ribbed formwork for construction, which is convenient for cast-in-place reinforced concrete beams, columns, floors and walls in construction projects. Background technique [0002] At present, construction projects generally use cast-in-place reinforced concrete beam-column floors and other structures. The basic procedures include erecting frames, installing steel bars, enclosing rigid formwork, tightening hoops, and then pouring concrete slurry for compaction. After the concrete is completely solidified and hardened After that, demould again. The rigid formwork used includes wood formwork, bamboo formwork, steel formwork, aluminum alloy formwork or reinforced plastic formwork. Although it can be used repeatedly, the process of formwork installation and formwork removal is complicated, time-consuming and labor-intensive, and the labor cost is high. What is even more troublesome ...
