Adjustable prestressed concrete box girder end formwork and reinforcing construction method
The invention discloses an adjustable prestressed concrete box girder end formwork and a reinforcing construction method.The end formwork comprises a wing plate, a top plate and a haunched end sealing formwork and further comprises a web plate, and the web plate comprises at least one telescopic plate; the upper transverse connecting plate is used for connecting the two adjacent wing plates, the top plate and the haunching end sealing template, and the lower transverse connecting plate is used for connecting the two adjacent webs; the telescopic fixing device is arranged on the telescopic plate and used for fixing the length of the telescopic plate; the prestressed duct adjusting device is arranged at the upper end of the web plate and/or between the telescopic plates of the web plate and/or on the wing plate, the top plate and the haunched end sealing template, the prestressed duct adjusting device is provided with a prestressed duct inserting piece, and a through hole is formed in the prestressed duct inserting piece; under the condition that the formwork is not replaced, the problem that formwork pipe hole positions corresponding to different prestressed pipes are inconsistent due to displacement of the positions of the prestressed pipes on the end faces of different box girder formworks can be solved.
本发明公开了一种可调节的预应力混凝土箱梁端头模板及加固施工方法，端头模板包括翼板、顶板及加腋端封模板，还包括：腹板，腹板包括至少一个伸缩板；上横向连接板和下横向连接板，上横向连接板用于连接相邻的两个翼板、顶板及加腋端封模板，下横向连接板用于连接相邻的两个腹板；伸缩固定装置，设置在伸缩板上，用于固定伸缩板的长度；预应力孔道调节装置，设置在腹板的上端和/或腹板的各伸缩板之间和/或翼板、顶板及加腋端封模板上，预应力孔道调节装置具有预应力孔道插片，预应力孔道插片上设置有通孔；发明可在不更换模板的情况下解决由于预应力管道位置在不同箱梁模板端面上变位，导致不同预应力管对应的模板管孔位不一致的问题。
