Problems solved by technology

For the first method, the sleeve grout exposed outside the prefabricated component is easy to harden due to hydration and dehydration, but the sleeve grout inside the prefabricated component is prone to settlement, grout leakage, The water absorption of the concrete in the wall causes holes to appear, resulting in the hidden danger of internal incompactness; for the second method, when the grouting is detected to be incompact, it is difficult to carry out later grouting due to the lack of grouting channels

Embodiment

[0031] Such as figure 1 As shown, the method for real-time monitoring of the density of steel sleeve grouting construction includes the following steps:

[0032] S1. Fix the density monitoring sensor on the top of the grouting sleeve: after adjusting the position of the sleeve rib 21 and the anchoring length to meet the design requirements, the prefabricated component 1 with the grouting sleeve 11 is hoisted to the upper surface of the underlying structure 2 Stop statically after 50cm of the working surface, fix several compactness monitoring sensors 31 on the inner top of the grouting sleeve 11, connect the sensor 31 to the data line 33 of the monitor 32 from the grout outlet, and then continue the prefabricated component 1 Hoist to the designated position and fix it effectively;

[0033] S2, sealing the grouting communication chamber 4;

[0034] S3. After the plugging structure of the connecting cavity 4 meets the grouting requirements, carry out the grouting construction ...

Abstract

The invention relates to the technical field of fabricated building construction, and discloses a real-time monitoring method for grouting construction compactness of a steel bar sleeve. The method comprises the following steps that 1, a compactness monitoring sensor is fixed at the top end in a grouting sleeve; 2, a grouting communicating cavity is sealed; and 3, in the construction process or after construction is finished, a compactness monitor is used for monitoring a sensor signal so as to monitor the grouting construction compactness. According to the monitoring method, real-time monitoring of the grouting construction compactness of the steel bar sleeve can be achieved, operation is convenient and easy, the existing fabricated building grouting construction technology can be effectively improved, the grouting compactness can be ensured, and the structural safety can be improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a method for real-time monitoring of the density of reinforcement sleeve grouting construction. Background technique [0002] With the steady advancement of new urbanization, the requirements of the whole society for building quality are gradually increasing. Prefabricated concrete buildings are of great significance to promote the development of construction industrialization, improve people's livelihood, and reduce energy consumption. Therefore, more and more new buildings adopt this construction method. [0003] The treatment technology of joints and joints directly affects the integrity and safety of concrete structures. The steel sleeve grouting connection technology is one of the effective ways to deal with joint connections. However, as a concealed project, the density of grouting is difficult to obtain intuitively. show. [0004] At present, ...
