Description

垂直刚性梁连接装置 技术领域
本实用新型涉及一种垂直刚性梁支座， 属于锅炉钢结构技术领域。 背景技术
一种产生蒸汽的设备，其包括一个炉体，该炉体具有一个管壁和至少一个垂 直刚性梁，该刚性梁靠近所述炉体的螺旋形管壁外表面。锅炉水冷壁螺旋段的刚 性梁往往采用网格式结构。垂直刚性梁位于两层水平刚性梁之间，并与水冷壁吊 带一一对应，起到加强水冷壁和保护吊带的作用。垂直刚性梁支座是垂直刚性梁 与螓旋水冷壁的连接方式。现有的支座型式主要由 U形板和管子构成。 U形板开 口的两边分别位于水冷壁吊带的两侧，并通过锯齿形的小钢板与螺旋水冷壁焊接 固定。 U形板的第三边与垂直刚性梁的翼缘贴近， 再用管子将 U形板的这条边夹 持在垂直刚性梁上。管子的上下两端分别通过小钢板与垂直刚性梁焊接。这样就 将 u形板和垂直刚性梁连接起来从而实现了螺旋水冷壁与垂直刚性梁的连接。同 时， 考虑到水冷壁的膨胀， u形板与垂直刚性梁、 管子及管子上下两端的小钢板 之间都留有一定的间隙。锅炉正压时， 压力经由 u形板传递给垂直刚性梁； 锅炉 负压时， 压力经由锯齿形小钢板、 u形板、 管子、 管子上下侧的小钢板传递给垂 直刚性梁。此种连接方式锯齿形小钢板与水冷壁在现场进行焊接，容易损坏水冷 壁管子， 连接结构复杂。
发明内容
本实用新型的目的是提供一种垂直刚性梁支座， 用于连接所述炉体管壁和 所述垂直刚性梁， 并在所述炉体管壁和所述垂直刚性梁之间传递力。
为了达到上述目的， 本实用新型的技术方案是提供一种垂直刚性梁支座， 其特征在于， 包括 H形钢， H形钢一侧的两个翼缘固定连接端板， 端板与固定在 垂直刚性梁上的 L形钢板相啮合， H形钢另一侧的两个翼缘固定连接设于螺旋水 冷管之间的小塞块， H形钢中部设有筋板。 本实用新型的 H形钢可选取轧制型钢或釆用钢板拼接构成。 另在 H形钢的 中部还装有筋板用于加强 H形钢和端板。端板的外表面与垂直刚性梁贴近。两块 L形钢板布置在 H形钢的上下两侧。 L形钢板的一边固定在垂直刚性梁上， 另一 边卡住端板。 这样就将 H形钢和端板的组合件与垂直刚性梁连接起来。 同时 L 形钢板与 H形钢和端板之间留有一定间隙以满足锅炉膨胀要求。一系列的小塞块 嵌于水冷壁管子之间并与之焊接， 小塞块外表面与管子相切形成两道平面。 H形 钢的两个翼缘分别靠在这两道平面上并与小塞块焊接。这样就将支座固定在水冷 壁上从而将水冷壁与垂直刚性梁连接起来。
本实用新型具有如下优点-
1. H形钢与端板的组合件比 U形板强度高；
2. 避免了支座工地安装时与水冷壁管子的焊接；
3. 增加了支座与水冷壁间的焊缝长度， 提高了连接强度；
4. 取消了锯齿形小钢板， 方便车间制造；
5. L形钢板与垂直刚性梁的连接强度更高；
6. 可通过增加 L形钢板的数量使支座承受更大的压力。
