Extra-large-tonnage prefabricated box girder end formwork and a mounting method
The invention relates to the technical field of railway prefabricated box girders, in particular to an extra-large-tonnage prefabricated box girder end formwork and a mounting method. The extra-large tonnage prefabricated box girder end formwork comprises a first formwork body and a second formwork body, the first formwork body is located at the top of the second formwork body, multiple sets of mounting holes are formed in a bottom plate of the first formwork body, multiple sets of through holes corresponding to the mounting holes are formed in a top plate of the second formwork body, and fasteners penetrate through the mounting holes and the corresponding through holes; the first template can rotate relative to the second template by loosening the fastening piece, and the first template can be locked at the top of the second template by tightening the fastening piece, that is, after the first template horizontally rotates relative to the second template, the first template is locked at the top of the second template by tightening the fastening piece; and therefore, the top plate of the box girder concrete formed by pouring can be connected with the adjacent top plate of the box girder concrete more tightly, an overlarge gap is prevented from being generated on the outer side part between the top plates of the box girder concrete at a small curve section, and the problem that an expansion joint is difficult to construct is solved.
本公开涉及铁路预制箱梁技术领域，尤其涉及一种特大吨位预制箱梁端模板及安装方法。特大吨位预制箱梁端模板包括第一模板和第二模板，第一模板位于第二模板的顶部，第一模板的底板开设多组安装孔，第二模板的顶板上开设有多组与安装孔对应的通孔，安装孔和对应的通孔中穿设紧固件；调松紧固件，第一模板能够相对第二模板转动，调紧紧固件，第一模板能够锁紧在第二模板顶部，即第一模板相对第二模板水平转动完成后，通过调紧紧固件将第一模板锁紧在第二模板顶部，进而能够使浇筑成型的箱梁混凝土的顶板能够与相邻的箱梁混凝土的顶板衔接的更加紧密，避免小曲线段处箱梁混凝土的顶板之间的外侧部分产生过大的缝隙，避免伸缩缝难以施工的问题。
