Description

Technical Field

[0001] The invention relates to the technical field of prefabricated prestressed double T-plates, and in particular to a detection device and method for the structural performance of prefabricated prestressed double T-plates. Background Art

[0002] Prefabricated prestressed double T-plate is a prefabricated reinforced concrete load-bearing component combining plates and beams. It has the characteristics of strong bearing capacity, good integrity and high lifting efficiency. It is widely used in construction projects such as bridges, houses, commercial centers and industrial plants. In order to verify whether the material quality and production process of prefabricated prestressed double T-plate meet the design requirements, sampling inspection is generally carried out before the prefabricated prestressed double T-plate leaves the factory. At this time, a detection device for the structural performance of prefabricated prestressed double T-plate is needed.

[0003] In the prior art, the existing detection device for the structural performance of prefabricated prestressed double T-plates can detect the bearing capacity of the prefabricated prestressed double T-plates when in use, thereby realizing accurate control of the bearing capacity of the double T-plates and providing key technical guarantees for the high-quality development of prefabricated buildings. However, it does not have the function of collecting and processing the concrete debris that falls when the bearing capacity of the prefabricated prestressed double T-plates is detected. That is, when the prefabricated prestressed double T-plates are tested for bearing capacity, as the loading process proceeds, microcracks are easily generated in the double T-plates, and these cracks will gradually expand, causing some concrete debris to fall and scatter on the workbench. In order to ensure that the subsequent detection of the prefabricated prestressed double T-plates is not affected, it is generally necessary for the staff to manually collect and process the concrete debris that falls on the workbench, which not only increases the working time of the staff, but also increases the workload of the staff, which reduces the use effect of the detection device for the structural performance of the prefabricated prestressed double T-plates, and also reduces the use efficiency of the detection device for the structural performance of the prefabricated prestressed double T-plates.

[0004] Therefore, we propose a detection device and method for the structural performance of prefabricated prestressed double T-slabs in order to solve the above-mentioned problems. Summary of the invention

In order to ensure that the subsequent detection of the prefabricated prestressed double T-plate is not affected, it is generally necessary for the staff to manually collect and process the concrete debris dropped on the workbench, which not only increases the working time and the workload of the staff, but also reduces the use effect of the detection device for the structural performance of the prefabricated prestressed double T-plate, and also reduces the use efficiency of the detection device for the structural performance of the prefabricated prestressed double T-plate.

The shell cover 104 is then removed, and the controller 113 is then connected to the battery 106. The shell cover 104 is then reset to its original position, and the pressure sensor 110 is then started using the controller 113. The two driving motors 107 are started at the same time by the cooperation of the housing 103 and the corresponding slide slots 102.

When the bottom end of the loading head 111 contacts the top of the prefabricated prestressed double T-plate and continues to move vertically downward, the pressure sensor 110 will transmit the detected pressure data to the controller 113 in the form of an electrical signal. At this time, the controller 113 will store the received pressure data in its internal storage module.

When the two L-shaped plates 205 rotate 135 degrees, the servo motor 206 is first turned off by the controller 113. At this time, the turned-off servo motor 206 will stop the rotation of the two L-shaped plates 205. At the same time, the concrete debris on the two L-shaped plates 205 will directly fall into the interior of the cabinet 201, and the concrete debris between the two L-shaped plates 205 will directly fall into the interior of the cabinet 201 with the cooperation of the perforated block 204. When the concrete debris on the two L-shaped plates 205 fall into the interior of the cabinet 201, the servo motor 206 is first started by the controller 113. At this time, the started servo motor 206 will stop the two L-shaped plates 205. When both L-shaped plates 205 are reset and rotated, the controller 113 can be used to directly turn off the servo motor 206. When the concrete debris inside the cabinet 201 needs to be removed, the controller 113 is used to turn off the electromagnet 214, and then the auxiliary block 211 and the hinge are used to apply a force to the cabinet door 210, so that the cabinet door 210 rotates. At this time, the rotating cabinet door 210 will drive the iron sheet 212 to rotate. When the cabinet door 210 rotates 180 degrees, the rotation of the cabinet door 210 is stopped first, and the iron sheet 212 is separated from the electromagnet 214. Then, the prepared tools are used to move the concrete debris inside the cabinet 201 to the prepared collection bucket. Then, the auxiliary block 211 and the hinge are used to make the cabinet door 210 reset and move. When the iron sheet 212 contacts the electromagnet 214, the controller 113 is used to directly start the electromagnet 214.
