[0035] like Figure 1As shown in the embodiment of this application, the connection node stress detection device is used to detect the connection strength between the beam 200 and the wall 100. The detection device includes: a reaction support 400, which is fixedly connected to the end of the beam 200 used for connection with the wall 100; a mounting support 500, which is fixedly connected to the wall 100 and located at the connection node between the wall 100 and the beam 200; and a hydraulic system, which includes a cylinder 600 and a detection component. The cylinder 600 is connected to the reaction support 400 and the wall 100. The mounting supports 500 are connected to the two ends of the hydraulic cylinder 600 through a detection component to detect the pressure at both ends of the hydraulic cylinder 600. In this way, the reaction support 400, mounting support 500 and hydraulic cylinder 600 simulate the connection between the beam 200 and the wall 100, so that the hydraulic cylinder 600 can detect the stress between the two, thereby realizing the detection of the stress at the connection node between the enclosure wall panel and the frame (such as the beam 200), so as to ensure the connection strength between the enclosure wall panel and the frame in the prefabricated building and reduce the safety hazards of the prefabricated building.

[0036] like Figures 2-3 As shown, the reaction support 400 includes a sleeve 410 and baffles 420 fixedly connected to both sides of the sleeve 410. The sleeve 410 is sleeved on one end of the crossbeam 200 for connection with the wall 100, and is fixedly installed to the first end of the hydraulic cylinder 600 through the baffles 420, so as to support the crossbeam 200 through the reaction support 400.

[0037] like Figures 2-3 As shown, a reinforcing rib 430 is fixedly connected between the side of the baffle 420 away from the oil cylinder 600 and the sleeve 410 to improve the support strength of the reaction support 400.

[0038] In some embodiments, the sleeve 410 is integrally cast with one end of the crossbeam 200 by pre-embedded casting to ensure the connection strength between the sleeve 410 and the crossbeam 200.

[0039] In some other embodiments, the sleeve 410 can be fixedly connected to the crossbeam 200 by the first bolt, so as to facilitate the disassembly and installation of the sleeve 410 and the crossbeam 200, so as to facilitate the reuse of the detection device and reduce the cost of use.

[0040] like Figure 2 As shown, the wall 100 includes a wall body 110 and a waler 120, with the waler 120 protruding from the wall body 110.

[0041] It should be noted that the waler 120 is a beam-like component that is installed on the wall body 110 and horizontally surrounds the building for a period of time or a section. The waler 120 mainly plays the role of "hooping" and "connecting", connecting the scattered vertical components into a whole, and enhancing the integrity and stability of the building.

[0042] like Figure 2 , Figures 4-5 As shown, the mounting bracket 500 includes a horizontal support plate 510 and a vertical connecting plate 520 that are fixedly connected. The horizontal support plate 510 is used to be fixedly connected to the waler 120 and is located at the bottom of the waler 120. One side of the vertical support plate 520 is fixedly installed to the second end of the hydraulic cylinder 600, and the other side of the vertical support plate 520 away from the hydraulic cylinder 600 abuts against the waler 120 to fix the hydraulic cylinder 600 to the reaction support 400 through the mounting bracket 500, so as to simulate the connection between the beam 200 and the wall 100.

[0043] like Figure 2 As shown, at least two reinforcing plates 530 are provided between the horizontal support plate 510 and the waler 120. The reinforcing plates 530 are horizontally arranged and distributed sequentially along the vertical direction. The uppermost reinforcing plate 530 abuts against the bottom surface of the waler 120 to further improve the support strength of the horizontal support plate 510. A vertical connecting plate 520 is fixedly connected to one side of the reinforcing plate 430, so that the waler 120 is fixedly connected to the reinforcing plate 530 and the horizontal support plate 510 by the second bolt 700.

[0044] Specifically, several corresponding through holes are provided on the waler 120, the reinforcing plate 530, and the horizontal support plate 510, so that the second bolts 700 pass through the through holes in sequence for connection, and the second bolts 700 correspond one-to-one with the through holes. Figure 2 Only one second bolt 700 is shown in the diagram to ensure the connection strength between the horizontal support plate 510 and the waler 120, and a pressure plate is provided between the second bolt 700 and the waler 120 to further increase the connection strength between the horizontal support plate 510 and the waler 120.

[0045] like Figure 2 As shown, a backing plate 540 is fixedly connected to both the side of the horizontal support plate 510 away from the vertical connecting plate 520 and the side of the reinforcing plate 530 away from the vertical connecting plate 520. The backing plate 540 abuts against the wall body 110 to evenly bear the abutting force between the backing plate 540 and the wall body 110, thereby further improving the support strength of the mounting bracket 500.

[0046] like Figure 2 , Figure 5 As shown, a bottom rib 550 is provided between the bottom of the horizontal support plate 510 and the backing plate 540 to further improve the support strength of the mounting bracket 500.

[0047] It should be noted that the horizontal support plate 510, the vertical connecting plate 520, the reinforcing plate 530, the backing plate 540, and the bottom rib plate 550 are all fixed together by welding to make the mounting support 500 a whole, so as to ensure the overall strength of the mounting support 500.

[0048] like Figure 1 As shown, an upper horizontal beam 300 is connected to the top of the wall body 110. The mounting bracket 500 also includes a support frame. The bottom end of the support frame is fixedly connected to the horizontal support plate 510, and the top end of the support frame is suspended on the upper horizontal beam 300 to provide vertical support force through the support frame, thereby further improving the load-bearing capacity of the mounting bracket 500.

[0049] like Figure 4 As shown, the support frame includes a first support rod 560, a second support rod 570, and a connecting crossbar 580; wherein, the bottom ends of the first support rod 560 and the second support rod 570 are welded and fixed to the horizontal support plate 510, and the top ends of the first support rod 560 and the second support rod 570 are welded and fixed to the connecting crossbar 580, so that the support frame as a whole has a V-shaped structure, thereby improving the load-bearing capacity of the mounting bracket 500.

[0050] In this application, the testing components include a hydraulic pump, a hydraulic valve, a pressure gauge, and hydraulic pipelines. Two oil ports at both ends of the cylinder 600 are connected to the hydraulic valves via hydraulic pipelines. A pressure gauge is installed on the hydraulic pipelines to detect the working pressure at both ends of the cylinder. The hydraulic pump, as a power source, supplies hydraulic oil to the corresponding chambers of the cylinder 600 through the hydraulic valves, ensuring the cylinder 600 provides support force. The pressure value is read by the pressure gauge, thus determining the axial force of the cylinder 600. The connection strength between the beam 200 and the wall 100 is obtained from the axial force of the cylinder 600, thereby determining the stress condition of the connection node between the beam 200 and the wall 100, ensuring the connection strength between the enclosure wall panel and the frame in prefabricated buildings.

[0051] The connection node stress detection device provided in this application embodiment simulates the connection between the beam 200 and the wall 100 through the reaction support 400, the mounting support 500 and the hydraulic cylinder 600. The hydraulic cylinder 600 detects the stress between the two, thereby realizing the detection of the stress at the connection node between the enclosure wall panel and the frame (e.g., the beam 200), ensuring the connection strength between the enclosure wall panel and the frame in prefabricated buildings, and reducing the safety hazards of prefabricated buildings.

[0052] The above description of the embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
