Slurry leakage prevention device and method for concrete formwork
The invention provides a grout leakage prevention device and method for a concrete formwork. The grout leakage prevention device comprises a soft grout stop ring, an active force application sleeve and a limiting mechanism. The soft grout stop ring is arranged at the steel bar through hole in the outer side of the template; the soft grout stopping ring is arranged on the reserved reinforcing steel bar penetrating through the reinforcing steel bar through hole in a sleeving manner; the active force application sleeve sleeves the periphery of the reserved steel bar; the grout stop ring fixing end is detachably connected with the soft grout stop ring through a detachable fixing mechanism, and a fixing plate is arranged at a port of the limiting connecting end. The limiting mechanism is arranged at the limiting connecting end of the active force application sleeve; the limiting mechanism comprises at least two limiting clamping jaws; the limiting clamping jaws are arranged on the periphery of the reserved steel bar in a surrounding mode. The problems that in the prior art, a grout stopping mode of a water absorption expansion type rubber grout stopping ring is not timely and insufficient and is influenced by a specific construction environment, and the grout stopping effect is not ideal can be solved.
本发明提供一种混凝土模板防漏浆装置及方法，包括软质止浆环、主动施力套筒和限位机构；软质止浆环设置在模板外侧的钢筋通孔处；软质止浆环套设在穿过钢筋通孔的预留钢筋上；主动施力套筒套设在预留钢筋的外周；止浆环固定端通过可拆卸固定机构与软质止浆环可拆卸连接，在限位连接端的端口设置有固定板；限位机构设置在主动施力套筒的限位连接端；限位机构包括至少两个限位卡爪；限位卡爪围设在预留钢筋的外周。通过本发明能够解决现有技术中的吸水膨胀式橡胶止浆环的止浆方式，存在不及时、不充分、被特定施工环境所影响，使得止浆效果不理想等问题。
