Description

Technical Field

[0001] The utility model belongs to the technical field of horizontal component support, and particularly relates to a support structure for dismantling horizontal components. Background Art

[0002] During the construction of deep foundation pits, in order to ensure the overall stability of the deep foundation pits, it is often necessary to set up internal support beams. The internal support beams are cast with reinforced concrete and need to be removed during the construction of the main structure of the basement. The internal support beams are generally removed by static blasting or rope saw cutting. The static blasting takes a long time, and there is a lot of concrete garbage after the blasting, which is not environmentally friendly. Therefore, the rope saw cutting method is used for the removal of internal supports in most projects. The internal support beams after cutting need to be temporarily shelved. When temporarily shelved, a strong support structure is required. Ordinary support methods are difficult to meet the strength requirements. At present, steel stirrups are usually used for support on construction sites. Since the steel stirrup legs are subjected to oblique force, the welding quality requirements are high, and the finished height of the steel stirrup is fixed, which cannot meet the requirements of multiple dismantling heights and is difficult to be used between horizontal components of different shapes.
