Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a steel-concrete composite construction anti-seepage casting mold. Background Technology
[0002] With the development of the construction industry, the level of construction is getting higher and higher, and the construction methods are becoming more and more diverse. Compared with traditional brick-concrete and frame structures, the new precast monolithic hybrid beam-column frame structure combines the advantages of steel structure and concrete structure, and has the characteristics of good seismic performance, fast construction speed and low cost. It mainly uses a structural form composed of precast concrete frame columns, precast concrete frame beams and steel end caps, and achieves rapid construction through factory prefabrication and on-site assembly.
[0003] Precast concrete frame columns and beams are connected on-site via steel ends. To enhance the fire resistance and overall appearance of the steel ends, on-site concrete pouring is required at the joints between the precast columns / beams and the steel ends. Existing casting molds for steel-concrete composite end beams typically use wooden molds with supports and foam sealant applied to the joints. However, these molds are not reusable, and improper application of foam sealant at the joints can lead to grout leakage, resulting in poor concrete pouring quality at the joints and affecting the appearance. This necessitates inconvenient post-construction repairs. Therefore, there is a lack of suitable reusable and leak-proof mold structures for this purpose, requiring improvement and optimization.
