Precast superposed beam and construction method
The invention provides a precast superposed beam and a construction method, and relates to the technical field of construction. The precast superposed beam comprises a precast part and a cast-in-placepart. The precast part comprises a steel truss and a precast concrete beam. A groove is formed in the top of the precast concrete beam. The lower portion of the steel truss is embedded into the precast concrete beam. The cast-in-place part comprises first cast-in-place concrete and a cast-in-place flange slab. The first cast-in-place concrete is filled into the groove, and the cast-in-place flange slab is arranged on the top of the precast concrete beam. The upper portion of the steel truss is embedded into the cast-in-place flange slab. The construction method includes a precast step and a cast-in-place step. The precast step includes the contents that the steel truss is put into a mold, and concrete is poured into the mold so as to form the precast concrete beam with the top being provided with the groove. The cast-in-place step includes the contents that the concrete is filled into the groove of the precast concrete beam and the cast-in-place flange slab is formed on the top of theprecast concrete beam. The beam and floor slabs of the precast superposed beam can use different kinds of concrete for pouring and cost is reduced. The construction cost of the construction method islow.
本申请提供了一种预制叠合梁及施工方法，涉及建筑技术领域。预制叠合梁包括预制部分和现浇部分。预制部分包括钢桁架和预制混凝土梁。预制混凝土梁的顶部形成有凹槽。钢桁架的下部埋设于预制混凝土梁内。现浇部分包括第一现浇混凝土和现浇翼缘板。第一现浇混凝土填充于凹槽内，现浇翼缘板设置于预制混凝土梁的顶部。钢桁架的上部埋设于现浇翼缘板内。施工方法包括预制步骤和现浇步骤，预制步骤包括将钢桁架置于模具中，向模具中浇筑混凝土以形成顶部有凹槽的预制混凝土梁。现浇步骤包括使混凝土填充预制混凝土梁的凹槽并在预制混凝土梁的顶部形成现浇翼缘板。预制叠合梁的梁与楼板可以使用不同的混凝土浇筑，节约了成本。施工方法的施工成本低。
