Novel prefabricated beam connecting joint
The invention discloses a novel prefabricated beam connecting joint. The invention belongs to the technical field of prefabricated beam connection. According to the scheme, just-stirred concrete is guided into the left side of a separation steel plate, so that the concrete enters guide holes, heat is transmitted to a buffer air bag to enable the buffer air bag to expand. When the buffer air bag isin contact with first conical thorns, the buffer air bag is broken, the concrete enters the right side of the separation steel plate through the guide holes; the heat of the concrete is transferred to a folding air bag through a fixed circular plate; therefore, ammonium bicarbonate powder in the folding air bag is heated and decomposed to generate carbon dioxide, ammonia gas and water, so that the folding air bag rapidly expands so as to push a steel guide pipe to pass through an active hole and to be inserted unto a storage groove; when a release rod enters the steel guide pipe and breaks the second sealing film, the steel guide pipe and the storage groove are filled with concrete after a through blocking ball is moved out of the air hole, and therefore the connecting strength of a firstprefabricated beam and the second prefabricated beam is improved.
本发明公开了一种新型的预制梁梁连接节点，属于预制梁连接技术领域，本方案通过将刚搅拌的混凝土导入到分隔钢板左侧，使得混凝土进入到导向孔内，通过将热量传递给缓冲气囊使得其膨胀，当缓冲气囊接触到第一锥刺后使得缓冲气囊破裂，从而使得混凝土通过导向孔进入到分隔钢板右侧，通过固定圆板将混凝土的热量传递给折叠气囊，从而使得折叠气囊内的碳酸氢铵粉末受热分解并产生二氧化碳、氨气和水，使得折叠气囊快速膨胀，从而推动钢导管穿过活动孔插入到收纳槽内，当释放杆进入到钢导管内并顶破第二封闭膜时，在通阻球移出透气孔后，使得钢导管和收纳槽内部充满混凝土，从而提高第一预制梁和第二预制梁的连接强度。
