Example Embodiment

[0036] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0037] The invention provides a stress-free water washing and chiseling method.

[0038] The method includes the following steps:

[0039] 1) Inspect and clean the template: Before construction, conduct a comprehensive inspection of the template and prepare the shaved solvent, clean the surface of the template, and do not apply the release agent on the part to be coated with the shaved solvent;

[0040] (2) Mark the area to be smeared: mark the area to be smeared on the part to be chiseled on the template;

[0041] (3) Applying chiseling solvent: evenly apply the prepared chiseling solvent on the part to be chiseled on the template with a brush;

[0042] (4) Pouring concrete: After evenly spreading, wait for the shaved solvent to air dry, then a...

Abstract

The invention provides a stress-free water-washing chiseling method, and belongs to the technical field of concrete surface chiseling. The method comprises the following steps of, carrying out comprehensive inspection on formwork before construction, preparing chiseling solvent, cleaning the surface stains of the formwork, using a brush to uniformly coat the prepared chiseling solvent on the formwork in a part to be chiseled, smearing the formwork uniformly, and fabricating the formwork for pouring concrete after the air drying of the chiseling solvent; removing the formwork after the concretestrength reaches the specified requirement of the corresponding structure; immediately washing away the laitance with high-pressure water after removing the formwork, and exposing aggregate; and checking whether there is a place where the chiseling solvent is not applied, wherein the chiseling solvent is a mixture containing hydroxyl groups, and the chemical formula of the chiseling solvent is C12H22O11. The method solves the problems of poor effect, low efficiency, high cost, large noise, dust pollution and the like of the traditional concrete chiseling process.

Description

technical field [0001] The invention relates to the technical field of chiseling on concrete surfaces, in particular to a stress-free washing chiseling method. Background technique [0002] More than 90% of expressway bridges are erected with prefabricated T-beams or box girders first simply supported and then continuously. The wet joints and construction joints of concrete structures need to be chiseled for construction, such as road bridges, especially prefabricated T-beams or boxes. The beams are first simply supported and then continuously erected. Before constructing wet joints, the concrete surface of the flange edge of the T-beam, the end of the diaphragm and the end of the beam must be chiseled clean to expose fresh stones. The most common chisel method is manual chisel Chiseling, but because there are many reserved connecting steel bars in these parts, workers need to spend a lot of energy to do it seriously and responsibly, otherwise the quality of wet joint conne...
