A grouting construction method for a prefabricated wall

Abstract

The invention discloses a grouting construction method of an assembly-type wall body, and relates to the technical field of assembly-type building construction. The method comprises the steps that a grouting material is constantly filled into a semi-grouting sleeve tube from a grouting port; when the grouting material is about to overflow from a grout discharging port, stuffing substances are usedfor rapidly stuffing, and the grout discharging port is sealed; after hole sealing is completed, a ventilating pipe penetrates through the stuffing substances, so that the ventilating pipe is allowedto extend to one end of the grout discharging port to reach the gap between both upper and lower reinforcing bars in the semi-grouting sleeve tube; when grout overflows from the ventilating pipe, theend, away from the semi-grouting sleeve tube, of the ventilating pipe is sealed until the grouting material is solidified. The grouting construction method has the advantages that the construction isconvenient, the construction cost is lower, the safety of the assembly-type building is helped to be improved, and the further development of the assembly-type building is promoted.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a grouting construction method for prefabricated walls. Background technique [0002] With the promotion of prefabricated buildings in the country, local government departments have made clear regulations on the assembly rate of construction projects in their regions, especially for the assembly rate of various components of prefabricated houses (such as walls, laminated boards, stairs, balcony lights). detailed regulations. [0003] like figure 1 As shown, the figure provides a schematic diagram of the construction of the semi-grouting sleeve in the prefabricated wall. In actual operation, the lower end of the steel bar 1 on the upper prefabricated wall is threadedly connected to the upper end of the semi-grouting sleeve 2, while the steel bar 1 on the lower prefabricated wall is threaded in the semi-grouting sleeve 2 from bottom to top; at the same...

Problems solved by technology

[0004] However, because the content of micro-swelling agent in grouting materials is not easy to control, the micro-swelling effect of grouting materials on the market is worrying.

The engineering quality supervision departments in Nanjing, Shanghai and other places in my country have repeatedly found construction quality problems of prefabricated wall components due to dissatisfaction with semi-grouting sleeve grouting, which has caused many experts to worry about the engineering quality of prefabricated structures; For this reason, the quality supervision departments in Shanghai, Nanjing and other places even expressly stipulate that prefabricated structures shall not participate in the quality excellence of local construction projects.
