Prestress combined steel pipe support

DAI XIANGSHENG

The invention relates to the field of foundation pit supporting equipment, in particular to a prestress combined steel pipe support. The combined steel pipe support comprises steel pipe pieces 1, annular hoop pieces 2 and supporting cross-shaped connecting pieces 3, wherein the plurality of parallel steel pipe pieces 1 are fixedly connected together through the annular hoop pieces 2 and the supporting cross-shaped connecting pieces 3 to form a supporting set, each of the steel pipe pieces 1 is formed by fixedly connecting a plurality of steel pipes end to end, the plurality of steel pipes forming the same steel pipe piece 1 are fixedly connected together through the supporting cross connecting pieces 3, and the supporting cross connecting pieces 3 on every two adjacent steel pipe pieces 1are fixedly connected together through connecting pieces 4. According to the prestress combined steel pipe support, the plurality of parallel steel pipe pieces are fixed through the annular hoop pieces and the supporting cross-shaped connecting pieces, and the steel pipes are connected and fixed through the supporting cross connecting pieces, so that the plurality of parallel steel pipe pieces form the support in a foundation pit. The prestress combined steel pipe support is simple in structure and capable of being rapidly disassembled and assembled, the cost is saved, and the assembling and disassembling efficiency is improved.

本发明涉及基坑支撑设备领域，尤其是预应力组合钢管撑。该组合钢管撑包括钢管件1、环形抱箍件2和支撑十字连接件3，数根相互平行的钢管件1通过环形抱箍件2和支撑十字连接件3固定连接在一起组成支撑组，钢管件1是由数根钢管首尾衔接固定组成，组成同一钢管件1的数根钢管之间通过支撑十字连接件3固定连接在一起，相邻的两个钢管件1上的支撑十字连接件3通过连接件4固定连接在一起。本申请通过环形抱箍件和支撑十字连接件来固定数根平行的钢管。通过支撑十字连接件来衔接固定钢管。从而使得数个平行的钢管件来组成基坑内的支撑。本申请结构简单，可快速拆装，节约了成本，提高了装卸效率。
