Abstract

The invention provides a foundation beam construction method, which comprises the following steps of: foundation trench excavation: increasing the excavation area of a foundation trench so as to facilitate operations of supporting a formwork by short vertical rods, removing the formwork and conveniently leveling the elevation; foundation treatment: compacting the dug foundation trench, digging outa soft soil layer with a preset thickness at a position with non-uniform soil texture in the foundation trench, then using a material with stable performance and no erosiveness as a cushion layer, and filling the dug soft soil layer; support construction: selecting a short rod with the length of 1.2-1.5 m as a vertical rod of a support; and formwork manufacturing: specifically, conducting blanking segmentation on the formwork according to a formwork splicing design drawing, and conducting splicing according to the formwork splicing drawing. According to the construction method, the frame bodyand the formwork are used for well isolating the groove bottom soil layer from poured concrete, the influence of site elevation on construction can be overcome, good effect on construction in rainy seasons is achieved, meanwhile, the cushion layer concrete curing period and the foundation beam groove bottom leveling procedure are omitted, the construction progress is greatly accelerated, and theconstruction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for foundation beam construction. Background technique [0002] At present, the cushion layer is the middle layer between the reinforced concrete foundation and the foundation soil. Its function is to make the surface flat to facilitate the binding of steel bars on it, and also to protect the foundation. It is all plain concrete and does not need to add steel bars. Construction generally requires its thickness to be more than 70mm and the strength grade to be above C10. [0003] The purpose of adding cushion to the foundation link beam is as follows: [0004] 1. Make up for the error of earthwork excavation through the leveling of the cushion layer, so that the force on the bottom plate is on the same plane, and the high-grade concrete of the foundation is not wasted. [0005] 2. The designed cushion generally protrudes 100mm from the bottom edge of the f...
