Pre-buried reserved hole device
The invention belongs to the field of building construction devices, and particularly relates to a pre-buried reserved hole device which comprises a prefabricated formwork, a locking bolt is slidably connected into the prefabricated formwork, a pre-buried box is placed at the position, located on the outer side of the locking bolt, of the upper end of the prefabricated formwork, and a sealing cover is movably connected to the upper portion of the outer side of the locking bolt. The bottom of the sealing cover is fixedly connected with a rubber plug, and the rubber plug is connected to the inner side of the embedded box in a sliding mode. The mounting sleeve is arranged on the outer side of the butterfly nut, and the protective shell is arranged on the outer side of the mounting sleeve, so that the exposed butterfly nut can be protected, concrete is prevented from being spilled on the butterfly nut when being poured on a prefabricated template, and the butterfly nut and the locking bolt can be conveniently disassembled in the later period; and after the mounting sleeve is sleeved with the protective shell, the protective shell can rotate and is fixed through the clamping blocks, and looseness is prevented.
本发明属于建筑施工装置领域，具体涉及一种预埋预留孔洞装置，包括预制模板，所述预制模板的内部滑动连接有锁紧螺栓，所述预制模板的上端且位于锁紧螺栓的外侧放置有预埋盒，所述锁紧螺栓的外侧上部活动连接有封盖，所述封盖的底部固定连接有胶塞，所述胶塞滑动连接于预埋盒的内侧。通过在蝶形螺母的外侧设置一个安装套，安装套的外侧配备防护壳，这样可以对裸露在外的蝶形螺母进行防护，防止预制模板上灌注混凝土时洒漏在蝶形螺母上，便于后期蝶形螺母与锁紧螺栓间的拆卸，另外，防护壳的内侧设置卡块，防护壳在套在安装套上后，可以旋转，并且通过卡块进行固定，防止松动。
