Description

A but, angle regulation removes support for detecting closely knit degree of bridge grouting

Technical Field

The utility model relates to a check out test set installation technical field especially relates to an adjustable angle removes support for detecting closely knit degree of bridge grout.

Background

The production process of the box girder plate of the large prestressed concrete bridge mostly adopts a post-tensioning method for processing, namely, a prestressed pipeline (a pore canal which is often said) is usually reserved, then concrete is poured, after the poured concrete reaches the specified strength, reinforcing steel bars in the reserved pipeline in the concrete are stretched and penetrated, anchorage is carried out on two sides of the box girder plate by using an anchorage device, and finally grouting is carried out in the prestressed pipeline (so as to prevent the corrosion of the prestressed reinforcement and increase the crack resistance and the durability of the structure), the grouting compactness has great influence on the strength of the box girder plate, the grouting incompactness not compactness not only can reduce the bearing capacity of the box girder plate, but also can easily cause the corrosion of the prestressed reinforcement at the defect position, and brings potential safety hazards to the bridge;

when the grouting compactness in the prestressed pipeline is detected, the prestressed pipeline has a certain curvature in the box girder plate, the angle of the infrared camera needs to be adjusted in real time (the infrared camera needs to be detected by a detector along the embedded trend of the prestressed pipeline in the box girder plate), and the detector holds the infrared camera for detection for a long time due to the long detection period, so that the detector is burdened (consumes more physical power), and the detection process is not facilitated to be performed durably and accurately;

in view of the above, we provide an adjustable angle mobile bracket for detecting the grouting compactness of a bridge, which is used for solving the above problems.

SUMMERY OF THE UTILITY MODEL

In order to the above situation, the utility model provides a but, but angle regulation removes support for detecting closely knit degree of bridge grout, but this angle regulation support has solved the inconvenience that traditional measurement personnel handheld infrared camera detected and brought, and the device can fold and can realize carrying out quick assembly disassembly to infrared camera, has also improved detection efficiency when making things convenient for measurement personnel to carry this equipment and changeing.

The utility model provides an adjustable angle removes support for detecting closely knit degree of bridge grout, includes the walking base, its characterized in that, it is equipped with the test table to rotate on the walking base and install two sets of landing legs and two sets of landing legs upper end, and is two sets of landing leg upper end all rotates with test table bottom and is equipped with positioner between installation and two sets of landing legs, it installs on the regulating plate and the regulating plate to rotate on the test table and demountable installation has infrared camera, the regulating plate is connected with and locates the adjusting device on the test table.

The beneficial effects of the technical scheme are as follows:

(1) the angle-adjustable support solves the inconvenience brought by the fact that a traditional detector holds an infrared camera for detection, the detector can detect the grouting compactness of the pipeline in the box girder only by moving the support along the pre-buried trend of the prestressed pipeline in the box girder, the two hands of the detector are liberated, and compared with the traditional mode that the detector holds the infrared camera for scanning detection, the detection process with a long period originally becomes easier;
