Technical Field
The utility model belongs to the technical field of construction of foundation pits in building engineering and the like, and particularly relates to a steel waist beam fixing and supporting member for a foundation pit.
Background
In recent years, with the development of large domestic construction, deep foundation pits are gradually increased, and a combined support system formed by pile rows, steel waist beams and anchor ropes is gradually applied to foundation pit engineering, in particular to deep foundation pit engineering due to good reliability, safety and adaptability of the combined support system to different rock and soil layers. The steel waist beam is used as a combined member made of section steel, has different design sizes, and is often used for supporting more than 2 steel waist beams in domestic foundation pit engineering. However, before the large-scale composite members such as the steel wales are manufactured, temporary supports are usually required to be arranged, so that the stability of the composite members is ensured. At present, in the manufacturing and installation process of a steel waist beam used in the building engineering, a bracket or a connecting plate is usually adopted for supporting the combined components by a supporting and fixing piece, but due to the fact that the bracket of a complex type is inconvenient to construct and certain deviation occurs in positioning in the pile arranging construction process, the steel waist beam cannot be conveniently installed and removed on site.
