Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a profiled steel internal support composite collar beam. Background Technique

[0002] With the continuous increase in the development degree of underground space, there often appear foundation pits with large excavation depths, large areas, and irregular plane shapes, which have higher requirements for the connection method, bearing capacity, and force transmission direction of the connecting components between steel supports. At present, when using profiled steel internal supports for foundation pit retaining, the steel collar beam and cast-in-place piles are basically connected through T-shaped or H-shaped steel force transmission components. The specific method requires breaking the protective layer of the cast-in-place piles at the position of the collar beam, welding the flanges of the force transmission components with the main bars of the steel collar beam and the supporting piles to form a whole. However, the welding amount is large, the welding quality cannot be guaranteed, the overall stiffness is relatively weak, the force transmission is not direct, and the gap between the steel collar beam and the cast-in-place piles is large. In addition, the flatness of the inner side of the foundation pit guardrail is not good, which easily makes the stress surface distribution between the profiled steel collar beam and the foundation pit retaining uneven, resulting in local deformation of the steel collar beam and the foundation pit retaining piles, and it is difficult to effectively bear the earth pressure from the outside of the foundation pit, leading to an increase in the displacement of the foundation pit.

[0003] The "composite collar beam for profiled steel internal support" disclosed in the patent publication number "CN221001038U" sets cast-in-place piles on the outside of the foundation pit, sets steel supports on the inside of the foundation pit, and a composite collar beam is arranged between the ends of the steel supports and the cast-in-place piles. The composite collar beam includes a steel collar beam and a concrete collar beam. The outside of the concrete collar beam is closely arranged with the cast-in-place piles. The concrete collar beam and the cast-in-place piles are provided with horizontally inserted main bars, and the concrete collar beam is also provided with diagonal tension bars; a steel collar beam is arranged inside the concrete collar beam, and the end of the steel support is directly connected to the steel collar beam.
