Before concrete is poured on the combined type four-limb truss, a disassembly-free template is paved on site, wherein the disassembly-free template is a steel plate net mold, a wood wool cement board or a fiber cement board and the like, and when the hybrid beam is manufactured, the steel plate net mold cannot be adopted as the template at the bottom of the hybrid beam; corresponding metal floor bearing plate is paved after the paving formwork, so that after concrete is poured, the mixed beam or the mixed shear wall is fixedly connected with the floor bearing plate, and the strength of the wall structure is guaranteed.
The embodiment mainly comprises the steps of pouring concrete on a construction site, vibrating the concrete simultaneously in the pouring process of the concrete, and effectively discharging air bubbles in the concrete.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
