Embodiment Construction

[0021] Such as figure 1 and figure 2 Shown, the construction method for derusting steel bars reserved for building in the present invention may further comprise the steps:

[0022] a. Prepare dry sand material. The particle size range of the sand material is 0.25mm~0.35mm. The sand material is made of quartz sand, corundum or mixed sand made of quartz sand and corundum.

[0023] B, prepare air compressor and sandblasting machine, according to sandblasting machine model, be equipped with corresponding specification air compressor, in the present embodiment, the height of sandblasting machine body is 1500mm, diameter 600mm, volume is 0.3 cubic meter, air The displacement of the compressor is 2 cubic meters per minute, and the rated power of the air compressor is 15Kw. There are movable casters at the bottom of the air compressor and the bottom of the sandblasting machine respectively. The air outlet of the air compressor is connected and communicated with the air inlet of the...

Abstract

The invention provides a construction method for derusting steel bars reserved for buildings. The specific steps are: a. preparing dry sand material; A sand delivery pipe is connected to the sand outlet of the sandblasting machine, and a spray gun is connected to the outlet end of the sand delivery pipe; c, close the air compressor and the sandblasting machine, add sand to the sandblasting machine, and add step a Prepared sand material; d, making the operating straight rod and the rod head cooperating with the operating straight rod; e, after adding the sand material, carry out the derusting operation on the front side of each steel bar of the reserved steel cage; f, Carry out derusting operations on the back and both sides of each steel bar of the reserved steel cage; g. After the derusting work is completed, clean the sand particles at the reserved steel cage. The cost of the derusting device used in the present invention is relatively low, and can effectively ensure the quality of the project, and has remarkable effects in saving economic costs and shortening the construction period.

Description

technical field [0001] The invention relates to a processing method for reserved steel bars in the field of building construction, in particular to a rust removal construction method for reserved steel bars for buildings. Background technique [0002] In the process of modern building construction, there are many large-scale projects or high-rise buildings with a long construction period. The post-cast belt and balcony concrete slabs are often equipped with reserved steel bars. These reserved steel bars are also bound to form a reserved steel bar cage. , and these projects are often the last to be constructed, and these reserved steel bars are easily corroded due to long-term exposure to the air, which in turn affects the quality of the project. During construction, some projects will also be shut down due to smog or winter, resulting in a large number of reserved steel bars being corroded due to the long reserved time. Especially in construction projects in coastal areas, t...
