T梁

產品詳情

T梁指截面形狀為T型的梁,兩側挑出的部分為翼緣,中間部分為梁肋,具有節約混凝土、減輕構件自重、提高跨越能力的特點。

T梁的承重結構由配筋混凝土的上翼緣和梁肋結合而成的梁式橋稱為T形梁橋,因主梁的截面形狀如英文字母T而得名。T形梁截面受壓區利用耐壓的混凝土做成翼緣板并兼作橋面;受拉區用鋼筋或預應力鋼筋承受拉力。

T梁的截面隨著翼板的寬度增大,可使受壓區高度減小,內力偶臂增大,使所需的受拉鋼筋面積減小。判斷一個截面是否屬于T形截面,不是看截面本身形狀,而是看其翼板是否參加抗壓作用。

安裝T梁的步驟:

1、運梁之前,我們要把T梁安裝好支座。為了T梁的運輸安全,工作人員正在細心安裝,確保T梁平穩安坐。

2、將T梁裝上運梁車

3、運梁車托運重達148噸重的T梁,行駛在平整的運梁便道上。

4、過孔作業前應安排好各關鍵部位負責人員,按照制定好的過孔工序進行,聽從統一指揮。在過孔過程中機臂水平度和柱體垂直度控制是關鍵點。

5、前后吊梁小車與曲梁穿銷軸聯接,解除曲梁與機臂銷軸聯接,固定好1#柱固定裝置。
