AI Technical Summary
In construction, the quality of the axillary angles of reinforced concrete structure beams and slabs is difficult to guarantee. It is often caused by inadequate vibration, such as honeycombs and lump surfaces, and the concrete pouring height is inconsistent, resulting in poor appearance quality.
A steel formwork including an axillary angle steel formwork, a connecting plate and a square tube was designed. The axillary angle steel formwork consists of a bent section and a slope section. The lower part of the bent section is slope-shaped, and a vibration opening is provided on the slope section. The square tube is detachably arranged on the bend section to ensure that the axillary angle is consistent with the concrete pouring height of the low wall.
Through this formwork, the concrete pouring quality at the axillary angle is significantly improved, avoiding problems such as honeycombs and linden noodles, and the appearance quality is also improved. At the same time, the vibration opening on the slope section ensures the compactness of the concrete.

At the same time, the concrete pouring heights of the corner low walls and beams are often not on the same horizontal plane, resulting in uneven horizontal construction joints and poor appearance of concrete pouring quality. Therefore, it is necessary to provide a steel formwork that can prevent corner defects, which can solve the problems of unstable corners that are prone to pouring quality problems and poor appearance of pouring quality in the prior art.
