Problems solved by technology

However, these repair methods seem rough, and the effect achieved will give people the feeling of excessive repair, and the cost of various additives used remains high, and it is impossible to achieve a smooth and beautiful effect without distortion. Therefore, the repair of fair-faced concrete faces many challenges. Economic and Perceptual Issues
[0003] Therefore there is above-mentioned inconvenience and problem in the repair mode of known fair-faced concrete body of wall

Embodiment 1

[0052] see now figure 1 , figure 1 It is a schematic structural diagram of wood-grain fair-faced concrete in an embodiment of the present invention. As shown in the figure, the defect repair principle of the concrete surface is that the fewer the repaired quantity and parts, the better.

[0053] The repairing method of load-bearing structure fair-faced concrete of the present invention may further comprise the steps:

[0054] a, substrate treatment, comprising the following steps:

[0055] (1) General defects do not need to be repaired. For obvious defects such as original wall pollution and grout leakage, appropriate repairs should be made, and there should be no particularly obvious color difference after repairing.

[0056] (2) On the whole, the surface layer is required to be basically flat, the color is natural, the edges and corners of the inner corners are neat and straight, the chamfers at the outer corners are set to be smooth, and the joints of the formwork should...

Abstract

The invention discloses a method for repairing load-bearing structure bare concrete. The method is characterized by comprising the following steps of a, substrate treatment; b, bare concrete defect repairing; c, bolt hole plugging treatment; d, protective agent construction. The method has the advantages that the repairing steps are elaborately designed, scientific and reasonable, operability is high, engineering quality is safe and reliable, the facade effect is good, the bare concrete obtains the scale feeling and the rhythm feeling, the special effect of the bare concrete vision is presented, under the condition that structural safety is not damaged, the bare concrete is repaired in an economical manner, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a method for repairing poured concrete walls, in particular to a method for repairing fair-faced concrete of a load-bearing structure. Background technique [0002] Chinese patent CN110847593A disclosed on February 28, 2020 a construction process for a gradually curved fair-faced concrete wall based on BIM technology, including a method for mixing fair-faced concrete, concrete proportioning, vibrating molding, and repairing methods. Among the repairing methods Record the joint grinding treatment. If there are detailed air bubbles, pockmarks, etc., it needs to be repaired with the mortar graded by the concrete manufacturer. The holes also need to be filled with fine stone concrete graded by the concrete manufacturer. The loose layer of the honeycomb needs to be removed, and the materials of the above manufacturers are also used. After being repaired, maintained, and polished, it is shaped, and the treatment measures need to be s...
