Construction method for reinforcing beam formwork at large-area concrete expansion joint
The invention relates to building construction, in particular to a construction method for reinforcing a beam formwork at a large-area concrete expansion joint. Comprising the following steps that A, a beam formwork is erected, and round holes are formed in a beam side formwork according to the reinforcing distance; b, beam steel bars are bound; c, a formwork supporting rod is additionally arranged; d, the formworks at the expansion joints are reinforced, opposite-pull screws are inserted into round holes of the side formworks, square steel pipes are installed on the opposite-pull screws at the expansion joints, U-shaped clamps are installed on the outer sides of the square steel pipes, flat steel is additionally arranged at the joints of the side formworks, and the flat steel is installed on the opposite-pull screws; e, concrete pouring; and F, removing the mold, and transferring to a lower expansion joint for use. The original construction technology is changed, the concrete forming quality is improved, the quality problems of slab staggering, beam section concave curvature and insufficient protection layers caused by unstable batten reinforcement are avoided, and the hidden danger of formwork explosion caused by unstable batten reinforcement in the concrete pouring process is avoided.
本发明涉及建筑施工，特别是一种大面积混凝土伸缩缝处梁模板加固的施工方法。包括如下步骤：A、梁模板支设，根据加固的间距在梁侧模板开圆孔；B、梁钢筋绑扎；C、加设支模棍；D、伸缩缝处模板加固，将对拉螺杆插入侧模板的圆孔，伸缩缝处的对拉螺杆安装方钢管，方钢管的外侧安装U型卡，侧模板接缝处加设扁钢，扁钢安装在对拉螺杆上；E、混凝土浇筑；F、拆模、周转至下处伸缩缝处使用。本发明改变原施工工艺，提高混凝土成型质量，避免由于木条加固不稳造成错台、梁截面凹曲、保护层不足的质量问题，避免在混凝土浇筑过程中出现由于木条加固不稳出现爆模的隐患。
