The invention belongs to the technical field of building prefabricated parts, and particularly relates to a weight-reducing prefabricated scissor ladder. The weight-reducing prefabricated scissor ladder comprises a prefabricated ladder section and an L-shaped ladder beam; the prefabricated ladder section comprises an upper ladder section and a lower ladder section; the upper ladder section is provided with an upper connection step, and the upper connection step is provided with a T-shaped pin key hole; the lower ladder section is provided with a lower connection step, and the lower connection step is provided with a straight pin key hole; the L-shaped ladder beam comprises a vertical section and a transverse section, the vertical section is provided with an upper anchor bolt, and the transverse section is provided with a lower anchor bolt; the upper anchor bolt is inserted into the T-shaped pin key hole; a gasket, which is arranged outside the upper anchor bolt in a sleeving mode and abuts against a step of the T-shaped pin key hole, is arranged in the T-shaped pin key hole; the upper end of the upper anchor bolt is in threaded connection with a nut abutting against the gasket; the portion, located above the gasket, in the T-shaped pin key hole is plugged through mortar; the lower anchor bolt is inserted into the straight pin key hole; a gap between the lower anchor bolt and the straight pin key hole is filled with grouting materials; and the space at the upper end of the straight pin key hole is blocked through mortar. According to the weight-reducing prefabricated scissor ladder, the hoisting problem can be solved, and the cracking risk caused by the slender ladder plate is avoided.
本发明属于建筑预制件技术领域,尤其涉及一种减重预制剪刀梯,包括预制梯段和L型梯梁,预制梯段包括上梯段和下梯段,上梯段具有上接驳台阶,上接驳台阶设有T型销键孔,下梯段具有下接驳台阶,下接驳台阶设有直型销键孔;L型梯梁包括竖向段和横向段,竖向段具有上锚栓,横向段具有下锚栓;上锚栓插入T型销键孔内,T型销键孔内设有套设在上锚栓外且抵接T型销键孔的台阶上的垫片,上锚栓的上端螺纹连接有抵紧垫片的螺母,T型销键孔内位于垫片之上通过砂浆封堵;下锚栓插入直型销键孔内,下锚栓与直型销键孔之间的缝隙通过灌浆料填充,直型销键孔上端空间通过砂浆封堵。本发明可解决吊重难题,又无需担心因梯板细长而造成开裂风险。
