Construction method of vertical construction joint of bare concrete facing

Abstract

The invention provides a construction method of the vertical construction joint of a bare concrete facing and relates to the technical field of on-site fabrication of building materials or building components. The construction method of the vertical construction joint of the bare concrete facing aims at solving the problem of poor building integral impression due to exposure of joints in walls, serious grout leakage and nonstraightness of the joints in existing processing technologies of the vertical construction joints of bare concrete facings. The method includes, firstly establishing a wall formwork, setting vertical splitting bars on the facing of a bare concrete wall I, removing the formwork after concrete is poured and reserving formwork end joints; secondly, removing the vertical splitting bars and the formwork end joints, digging out a bar-shaped block from the surface layer of the wall between the vertical construction joints and grooves formed in the facing of the bare concrete wall I; thirdly, re-embedding the vertical splitting bars into the grooves, establishing the formwork of a bare concrete wall II, pouring concrete into the formwork and removing the formwork and the vertical splitting bars to obtain the bare concrete wall II connected with the bare concrete wall I.

Description

technical field [0001] The invention relates to the technical field of on-site preparation of building materials or building components, in particular to a construction method for vertical construction joints of fair-faced concrete finishes. Background technique [0002] Clear-water concrete veneer has an unpretentious, natural and steady appearance charm. Its inherent thickness and elegance are unmatched by some modern building materials. Clear-water concrete veneer not only has rich spiritual connotations, but also has environmental protection, Energy-saving features. With the wide application of fair-faced concrete finishes, there are more and more buildings with large volumes and large facades, and the quality requirements for fair-faced concrete finishes are also gradually increasing. [0003] Fair-faced concrete finishes require construction joints to be straight and free of staggered steps. However, in the existing fair-faced concrete facing construction, there is a...
