The utility model relates to a fine-tuning device for assisting the precise positioning of U-shaped ribs. The utility model comprises an inverted U-shaped support, two steel wedges and a hammer; The two lower ends of the inverted U-shaped support are respectively fixed on the top surface of the steel plate used to install the U-shaped rib 4 and are located outside the two lower ends of the U-shaped rib; Two steel wedges are respectively inserted between one lower end of the inverted U-shaped support and one lower end of the adjacent U-shaped rib; The hammer is held by the construction personnel and is used to knock the steel wedge to shrink the U-shaped rib 4. The effect of the utility model: it solves the problem of inaccurate positioning in the assembly process of U-shaped ribs, shortens the assembly time of U-shaped ribs, greatly improves the assembly accuracy of U-shaped ribs, ensures that the lines of U-shaped ribs are straight and beautiful, and ensures the overall stress stability of steel box girders. In addition, the micro adjustment device also has the advantages of low construction cost, simple operation, repeated construction, and operation after simple training. It can be operated after simple training. It can be operated after simple training< br/>
【技术实现步骤摘要】
一种用于辅助U形肋精准就位的微调装置
[0001]本技术属于钢箱梁施工辅助工具
,特别是涉及一种用于辅助U形肋精准就位的微调装置。
技术介绍
[0002]近年来随着环保要求的逐年升级和冶炼技术的不断提高,钢结构桥梁以其强度高、自重轻、施工速度快等优势逐渐取代了传统的混凝土结构桥梁,并且钢结构桥梁上的钢箱梁施工技术也随之日趋完善。桥箱梁的纵肋主要采用U形肋,原因是U形肋能够提供较大的抗扭刚度和抗弯刚度,可以改善整个桥面板的受力状态。但是,如果U形肋拼装时出现扭曲现象,则会对整个钢结构桥梁产生不良影响,在板单元制作过程中如果U形肋拼装定位不精确,则会在相邻梁块拼装过程中发生U形肋的嵌补段或者U形肋连接板错台的现象,导致不能精准安装,从而影响钢箱梁的整体受力。
[0003]现有技术中的U形肋安装定位仍采取锤击、千斤顶挤压等方式,缺点是操作过程繁琐、复杂,目前一般钢箱梁上顶板、底板均布置有U形肋,采取上述办法会导致整体制作工期增加、成本升高等问题。
技术实现思路
[0004]为了解决上述问题,本技术目的在于提供一种用于辅助U形肋精准就位的微调装置。
[0005]为了达到上述目的,本技术提供的用于辅助U形肋精准就位的微调装置包括:倒U形支架、两个钢楔和铁锤;其中,所述倒U形支架的两个下端分别固定在用于安装U形肋4的钢板顶面上位于U形肋两个下端外侧的部位;两个钢楔分别插入在倒U形支架的一个下端与相邻的U形肋一个下端之间;铁锤由施工人员手持,用于敲击钢楔而使U形肋4产生缩口。
