Device for monitoring grouting compactness of prefabricated building, automatically compensating and verifying strength of grouting material

Abstract

The invention discloses a device for monitoring the grouting compactness of a prefabricated building, automatically compensating and verifying the strength of a grouting material. The device comprises a communicating pipe, a standard sample reserving device, a communicating pipe, a compensating and observing device and an anti-backflow device. The standard sample reserving device is connected with a slurry discharging port of the conventional sleeve through a communicating pipe, a compensation and observation device is arranged above the standard sample reserving device, and a backflow prevention device is arranged above the compensation and observation device. When the device is used, whether the grouting quality meets the requirement or not can be judged according to the position of the grout level of the grouting material in the compensation and observation device, and when the quality is not met, grouting material compensation can be automatically conducted on the sleeve. The problems that the grouting compactness of the fabricated building is difficult to guarantee and detect, and the strength of the grouting material cannot be verified can be effectively solved, and the building quality of the fabricated building can be effectively improved.

Description

technical field

[0001] The invention relates to the field of prefabricated concrete structures, and relates to a device for monitoring fullness of prefabricated building grouting, automatic compensation and verification of grouting material strength. Background technique

[0002] In recent years, prefabricated concrete buildings have developed rapidly in my country, and steel sleeve grouting connection is a commonly used connection node form in prefabricated building structures. In actual construction, the grouting construction is concealed due to the narrow and closed interior of the steel sleeve, and it is difficult to directly detect and control it.

[0003] my country's prefabricated concrete buildings started late, and the relevant testing methods and standards are not yet perfect. Whether the grouting fullness reaches the standard and whether the strength of the grouting material meets the requirements has always plagued the development of prefabricated buildings in m...

Embodiment Construction

[0039] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the materials and methods involved in the following specific devices are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0040] see Figure 1 to Figure 7 , this embodiment provides a device for monitoring the fullness of grouting in prefabricated buildings, automatic compensation and verification of grouting material strength, including a standard sample holder 9, a compensation and observer 11, an anti-backflow device 12, a first communication Pipe 8, second connecting pipe 10, third connecting pipe 13. The internal size of the standard sample retainer 9 is 160mm×40mm×40mm, it is pre-embedded in the vertical member 1, flush with the outer surface of the vertical member 1, and the standard grouting material can be directly observed fro...
