Description

Technical Field

[0002] With the continuous progress of society, people have different standards and requirements for the convenience, quality, and uniformity of buildings. Among them, prefabricated infill walls can be successfully manufactured in the factory and then transported to the construction site for assembly. Prefabricated infill walls have the characteristics of uniform specifications, convenient installation, and easy quality control, and are chosen by more and more people. However, in order to ensure the safety of prefabricated infill walls after they are manufactured, it is necessary to sample the prefabricated infill walls and conduct strength testing.

[0003] Existing prefabricated infill walls are usually composed of wall panels and internal steel support brackets. During inspection, the prefabricated infill wall to be inspected needs to be pulled to the inspection area, and then the prefabricated infill wall is erected and fixed. After the fixation is completed, the prefabricated infill wall is subjected to strength testing. However, during the inspection process of the prefabricated infill wall, since the prefabricated infill wall is usually large in size, it is inconvenient to place it vertically and fix it, which not only affects the inspection efficiency of the prefabricated infill wall, but also easily injures the fixing staff during the fixing process.

[0035] Embodiment two

[0036] As Figures 1-8As shown, based on the above embodiment, this embodiment further provides the following content:

[0037] When the infill wall 7 is in use, concrete needs to be poured into the infill wall 7. However, during the cooling and forming process, the concrete will expand and deform. Therefore, in order to ensure that the strength of the infill wall 7 is not affected by the concrete, this embodiment provides the following design:

[0038] The first detection assembly 5 includes a first detection hydraulic rod 51, a connecting frame 52 and a filling nozzle 53. The first detection hydraulic rod 51 is arranged in the middle of the installation top plate 32. The bottom end of the first detection hydraulic rod 51 is connected to the connecting frame 52. The connecting frame 52 has an N-shaped structure. One end of the connecting frame 52 is connected to the bottom end of the first detection hydraulic rod 51. The other end of the connecting frame 52 is provided with a filling nozzle 53. The filling nozzle 53 is located above the vertical filling wall 7. The connecting frame 52 is engaged and slidably engaged with the installation top plate 32. The filling nozzle 53 is provided for pouring the concrete to be filled into the interior of the filling wall 7.

[0039] When inspecting the filling wall 7, the connecting frame 52 and the mounting top plate 32 are engaged and slid, so that the filling nozzle 53 can be inserted into the filling wall 7 to fill the concrete. The raised and lowered filling nozzle 53 can evenly and fully pour the concrete into the filling wall 7, thereby ensuring that after the concrete inside the filling wall 7 cools and expands, the filling wall 7 can be evenly stressed and feedback can be obtained. In conjunction with the ranging module 63 in the second detection component 6, it is convenient to more accurately detect the compressive and anti-expansion performance of the filling wall 7 after the concrete is poured.

[0040] Example 3

[0041] like Figures 1-8 As shown, based on the above embodiment, this embodiment further provides the following content:

[0042] In order to enable the assembled infill wall strength detection device to detect the entire structural wall of the infill wall 7, this embodiment provides the following technical solutions:

[0043] An electric slide rail 311 is provided on the inner side of the mounting vertical plate 31. The second detection assembly 6 includes a second detection hydraulic rod 61, a connecting block 62, a distance measuring module 63, a pressure plate 64 and a force measuring module 65. The outer side of the second detection hydraulic rod 61 is provided with a connecting block 62, and the connecting block 62 is connected to the electric slide rail 311. The top surface of the second detection hydraulic rod 61 is provided with a distance measuring module 63 for detecting the infill wall 7. One end of the second detection hydraulic rod 61 is provided with a pressure plate 64 for detection, and the inner side of the pressure plate 64 is provided with a force measuring module 65. The second detection hydraulic rod 61 cooperates with the pressure plate 64 to squeeze the vertically fixed infill wall 7 for strength detection. The force measuring module 65 is used to feedback the force condition of the infill wall 7.

[0044] The mounting vertical plate 31 is engaged and slidably engaged with the second detection hydraulic rod 61. An adjusting rod 221 is provided on the inner side of the supporting plate 22. There are multiple adjusting rods 221. The adjusting rods 221 are rotatably connected to the supporting plate 22.

[0045] By rotating the adjusting rod 221 on the support plate 22, the filling wall body 7 can be moved longitudinally on the support plate 22, and the second detection hydraulic rod 61 slides and rises in the middle of the installation vertical rod, so that when the second detection component 6 performs pressure strength detection on the filling wall body 7, the detection part of the filling wall body 7 can be adjusted more conveniently, thereby facilitating the strength detection device to accurately detect the strength data of various parts of the filling wall body 7.

[0046] The working principle and use process of the present invention:

[0047] When using:

[0048] First, place the placement plate 21 in a flat state, then place the infill wall 7 that needs to be strength tested on the placement plate 21. At this time, the infill wall 7 will contact the auxiliary placement rod 211. The auxiliary placement rod 211 rotatably connected to the placement plate 21 can make it easier to push the infill wall 7 toward the support plate 22. When the infill wall 7 is pushed to contact the support plate 22, the motor 23 installed on the top plate 32 is started. The motor 23 drives the reel 24 to rotate the winding rope 25. The rope 25 connected to the outer end of the placement plate 21 can pull the placement plate 21. At this time, the placement plate 21 drives the infill wall 7 to rotate upward with the inner end as the point. In this way, the vertical fixation test of the infill wall 7 can be made more labor-saving and convenient.

[0049] Then lift up the fixed plug plate 212 inside the placement plate 21, and the fixed plug plate 212 will be embedded in the fixed slot on the bottom surface of the installation top plate 32. The fixed plug plate 212 engaged with the installation top plate 32 can limit the placement plate 21 and the filling wall 7 after rotation. At the same time, the fixed hydraulic rod 41 in the fixing assembly 4 can push the fixed push plate 42 to squeeze the filling wall 7, thereby further fixing and supporting the vertical filling wall 7.

[0050] When testing:

[0051] The filling nozzle 53 can pour concrete into the filling wall 7, simulating the use of the filling wall 7. Then, the first detection hydraulic rod 51 controls the connecting frame 52 to drive the filling nozzle 53 to rise and fall. The rising and falling filling nozzle 53 can evenly and fully pour concrete into the filling wall 7. In this way, after the concrete is poured into the filling wall 7, the cooling expansion of the concrete can fully transmit the tension back to the filling wall 7.

[0052] After the concrete inside the filling wall 7 cools down, the ranging module 63 in the second detection component 6 can detect the wall thickness and other data of the filling wall 7 to detect the compressive and expansion resistance of the filling wall 7 during actual use, so as to make the use of the assembled filling wall after detection safer and of better quality.

[0053] During the testing process;

[0054] The second detection hydraulic rod 61 controls the pressure plate 64 to squeeze the filling wall body 7 before or after filling. Through the continuous pressure of the second detection hydraulic rod 61, the compressive strength of the wall panels of the filling wall body 7 itself and the internal steel frame is detected. Then, before the pressure plate 64 squeezes the filling wall body 7, the electric slide rail 311 installed on the inner side of the vertical plate 31 can be used to control the lifting and lowering of the second detection hydraulic rod 61 and the pressure plate 64. The rotating adjustment rod 221 on the support plate 22 can also make it easier for the inspector to change the position of the filling wall body 7 on the support plate 22. In this way, it is convenient for the strength detection device to perform strength detection on multiple positions of the filling wall body 7, thereby ensuring the accuracy of the data detected by the strength detection device on the filling wall body 7.
