A structure that shears that is used for steel lattice column and is connected against making concrete structure roof beam

The utility model belongs to a structure that shears that is used for steel lattice column and is connected against making concrete structure roof beam in excavation supporting field, technical schemeis: in the reverse construction method excavation supporting engineering, the steel lattice column of in advance construction is post -construction's the contrary vertical support structure who makesconcrete structure roof beam the steel lattice column with the steel that shear are welded in the contrary crossing partial outside all around of making concrete structure roof beam. The utility model discloses it is simple reliable, thus come reinforcing and contrary the work through the steel that shear in the side welding of steel lattice column and being connected of concrete structure roof beam improve the bearing capacity that shears. 本实用新型属于基坑支护领域的种用于钢格构柱与逆作砼结构梁连接的抗剪构造，技术方案为：在逆作法基坑支护工程中，先行施工的钢格构柱为后施工的逆作砼结构梁的竖向支承结构，在所述钢格构柱与所述逆作砼结构梁的相交部分的四周外侧焊接抗剪钢材。本实用新型简单可靠，通过在钢格构柱侧面焊接抗剪钢材来增强与逆作砼结构梁的连接从而提高抗剪承载力。
