Description
Technical Field
The utility model relates to a connecting piece in assembly type structure field, concretely relates to grout sleeve and benefit thick liquid device for V type grout outlet steel bar connection.
Background
At present, the extensive application of grout sleeve grout connection technique is in the fabricated construction, the fabricated construction prevalence is also higher and higher, but in the actual engineering because the construction is not normative inadequately, and the fabricated construction material quality is uneven, the phenomenon ubiquitous that the grout is not full, very big potential safety hazard has been brought for the engineering, the grout technique of present universal adoption is UNICOM's chamber grout, in time plug up after grout outlet, arrange the thick liquid mouth and go out the thick liquid, unable real time monitoring grout condition in the grout process, the condition of inspection grout plumpness after the grout construction is accomplished generally adopts drilling observation, the condition that the grout is not full generally adopts the syringe to mend the technology of thick liquid, the operation is very loaded down with trivial details and consuming time, and the theory of green with the fabricated construction is contradicted.
For example, in 2019, a steel bar grouting sleeve with a grout outlet inclined upward and a connection structure thereof are disclosed in the chinese utility model patent (publication No. CN208763307U), wherein a grouting opening and a grout outlet are formed in the sleeve wall of the sleeve, the grouting opening is perpendicular to the wall of the bottom end portion, the grout outlet is inclined upward relative to the wall of the top end portion, and the inner surface of the sleeve wall protrudes inward to form annular inward protrusions arranged at intervals. This grout sleeve can improve the not full condition of grout through the setting of the grout outlet of slope, but still need use the depth measurement chi at the inspection of the grout plumpness at the actual grout in-process, can not the full condition of visual observation grout.
