Problems solved by technology

However, due to the steel material used for the sleeve and the narrow space inside the sleeve, the existing inspection and acceptance methods cannot be inspected. This is an important problem in the promotion of prefabricated structures, which directly affects the construction industrialization. Therefore, it is urgent to develop a detection device and method for sleeve grouting compactness

Embodiment 1

[0040] This embodiment discloses a system for detecting the density of grouting materials in steel bar sleeves, such as figure 1 As shown, it includes a sleeve 2 for connecting the steel bar 1, and the inside of the sleeve 2 is provided with a grouting material 3 through the grout inlet 21 and the grout outlet 22 provided on the sleeve 2, and is characterized in that:

[0041] A signal conduction rod 4 is also arranged inside the sleeve 2, and a data acquisition device is arranged outside the sleeve 2;

[0042] The data acquisition device comprises a signal transmitter 7, a signal receiver 8 and a data processor 10 for statistical analysis of signals, and the signal transmitter 7 and the signal receiver 8 are all electrically connected to the data processor 10;

[0043] One end of the signal conducting rod 4 is connected to the signal transmitter 7 through the pulp inlet 21, and the other end of the signal conducting rod 4 is connected to the signal receiver 8 through the pulp...

Embodiment 2

[0065] This embodiment discloses a system for detecting the density of grouting materials in steel bar sleeves. The structural difference between it and Embodiment 1 lies in:

[0066] In this embodiment, the signal transmitter 7 is an oscillator for transmitting vibration waves.

[0067] The detection method of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0069] This embodiment discloses a detection method of a detection system for the density of grouting materials in steel bar sleeves, and its difference from Embodiment 1 in steps lies in:

[0070] S3. When the grouting material 3 in the sleeve 2 reaches half, set the seals on both ends of the signal transmission rod 4 and seal the grout inlet 21 and the grout outlet 22 to form a sleeve connector;

[0071] All the other steps are the same as in Example 1.

[0072] The detection result of this embodiment is as follows Figure 5 As shown, in the figure, the abscissa x is the receiving time, and the ordinate y is the amplitude of the sound wave; compare the reference example of the present embodiment Image 6 As shown, it can be seen that the filling of the grouting material 3 in the sleeve 2 detected in this embodiment is not dense.

Abstract

The invention discloses a reinforcement sleeve grouting material compactness detection system which comprises a sleeve, wherein the sleeve is connected with a reinforcement part; the sleeve is filledwith a grouting material through a slurry inlet and a slurry outlet in the sleeve; the sleeve is also internally provided with a signal conduction rod; a signal transmitter, a signal receiver and a data processor for signal counting and analysis are arranged outside the sleeve; both the signal transmitter and the signal receiver are electrically connected with the data processor; one end of the signal conduction rod is connected with the signal transmitter through the slurry inlet; the other end of the signal conduction rod is connected with the signal receiver through the slurry outlet; sealing parts are arranged at both the slurry inlet and the slurry outlet. The invention further discloses a detection method of the reinforcement sleeve grouting material compactness detection system. Byadopting the reinforcement sleeve grouting material compactness detection system, not only is compactness of the grouting material in the sleeve conveniently and rapidly detected, but also accurate detection results can be achieved, and the connection reliability of the sleeve and the reinforcement part can be improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering detection, and in particular relates to a detection system and a detection method for the density of grouting materials in steel bar sleeves. Background technique [0002] Prefabricated concrete structure is one of the key structural forms in the evolution of my country's housing industry, and it has the characteristics of high efficiency, low energy consumption and environmental protection.
