Building method for controlling temperature cracks of masonry

Abstract

The invention relates to a building method for controlling temperature cracks of a masonry, which comprises the following steps of: A. pouring water over bricks and fully soaking the bricks before brick laying, ensuring that the water content ratio of fly ash bricks is 8 to 12% and the water absorbing depth around the cross section of each fly ash brick is 15 to 20mm; B. locating, paying-off and laying bricks; C. building a brick masonry, wherein a control joint and a concrete slab strip of a steel bar are arranged on the brick masonry so as to control masonry damage caused by temperature fluctuation and drying shrinkage and deformation of materials: and D. carrying out sedimentation and maintenance after the brick laying of a wall is completed. The invention has the advantages that: in the process of the brick masonry construction of a transformer substation building, the cracks caused by temperature and material shrinkage are greatly reduced; from the application condition of the transformer substation construction, the building method has obvious effects, and the temperature cracks of the masonry are better controlled; from the aspect of economic benefit, the recovery rate of guarantee deposit is increased; meanwhile, the improvement for construction quality ensures the safe operational performance of the building, and favorable social benefit is obtained.

Description

technical field [0001] The invention belongs to the field of construction and relates to a construction method for controlling temperature cracks in masonry. Background technique [0002] In recent years, the substation projects built by our company often have cracks in the building masonry, especially between the door, window opening or between the filled wall and the frame column, cracks often appear and cause water seepage in the wall. The final quality of the substation is greatly reduced. The current construction method can not get better control effect. [0003] Due to the existence of temperature cracks in building masonry during substation construction in recent years, the quality of the wall has been reduced, which has a great impact on the commissioning of the entire project and will also have a negative impact on our company's future participation in market competition. Temperature cracks: Temperature changes will cause thermal expansion and cold contraction of ...
