Problems solved by technology

The sealing material generally uses cement-based mortar, which takes a long time to set, and is prone to leaks due to unreliable sealing. The sleeve grouting material also takes a long time to set, and it takes 24 hours to reach the predetermined strength requirement.
This form of technology leads to the extension of the construction period, which restricts the development of the rapid construction concept of prefabricated buildings
[0004] Therefore, it is of great significance to develop a method for rapid grouting construction of prefabricated concrete buildings and improve the current situation of long grouting construction period, which is of great significance for promoting and accelerating the development of prefabricated buildings

Abstract

The invention discloses a rapid grouting construction method for fabricated concrete construction. The rapid grouting construction method comprises the following steps: step one, carrying out edge sealing on grouting cavities by an assembled edge sealing device; step two, uniformly stirring sleeve grouting material slurry used for connecting early strength reinforcing steel bars; step three, injecting the sleeve grouting material slurry used for connecting early strength reinforcing steel bars in the step two into the grouting cavities in the step one through a grouting machine. A multi-channel converter is used for injecting the uniformly stirred sleeve grouting material slurry used for connecting early strength reinforcing steel bars into a plurality of grouting cavities simultaneously,and the technical requirement that the compressive strength of the grouting material is 35 MPa within 2h can be achieved. The rapid grouting construction method can be widely applied to rapid groutingconstruction of fabricated concrete construction, and has the advantages of wide material acquisition range, simple and efficient construction, edge sealing material cyclic utilization, energy conservation, environmental protection and the like.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a rapid grouting construction method for prefabricated concrete buildings. Background technique [0002] In recent years, prefabricated integral concrete structures have been widely promoted and implemented in the field of construction because of their significant advantages in engineering quality, energy conservation, environmental protection, and social benefits. The advanced prefabricated component connection technology realizes the effective connection of the stressed steel bars of the assembled integral concrete structure. [0003] Usually, the construction process of steel bar sleeve grouting connection is mainly to seal the grouting chamber after the prefabricated components are installed and fixed on the construction site, and then use the sleeve grouting material mixture for sleeve grouting. Cement-based mortar is generally used as the sealin...
