[0036] As shown in the appended Figure 1 - appended Figure 4 figures, the present invention provides an assembled joint angle monitoring device for monitoring the relative angle between a monitored member I 10 and a monitored member II 11, which can be applied to the verticality monitoring of the assembly of assembled joints in an assembled building structure, and includes a straight rod 1 and at least two groups of arc-shaped telescopic rods 2;

[0037] The arc-shaped telescopic rod 2 includes an arc rod I 201 and an arc rod II 202. The arc rod I 201 and the arc rod II 202 move on the same circular arc, that is, the arc rod I 201 and the arc rod II 202 are coplanar, have the same radius, and share the same center point. At this time, the arc rod I 201 and the arc rod II 202 move relative to each other on the same circular arc to achieve expansion and contraction, that is, the two arc endpoints of the arc-shaped telescopic rod 2 formed by the arc rod I 201 and the arc rod II 202 can approach and move away from each other. At least two groups of arc-shaped telescopic rods 2 have the same radius and share the same center point, that is, multiple groups of arc-shaped telescopic rods 2 are not coplanar and are located on the same spherical surface;

[0038] The outer ends of at least two of the arc-shaped rods I 201 are fixedly connected to one end of the straight rod 1. At this time, the outer ends of the plurality of arc-shaped rods I 201 and one end of the straight rod 1 are fixed to each other at the same point. The outer end of the arc-shaped rod II 202 is used for rotational connection to the monitored component I 10. It should be noted that the outer end of the arc-shaped rod I 201 is the end of the arc-shaped rod I 201 away from the arc-shaped rod II 202, and the outer end of the arc-shaped rod II 202 is the end of the arc-shaped rod II 202 away from the arc-shaped rod I 201. The other end of the straight rod 1 One end is used to be fixed on the monitored component Ⅱ11, and is fixedly connected to the monitored component Ⅱ11 at the end of the straight rod 1. After the outer ends of multiple arc rods Ⅱ202 are rotatably connected to the monitored component Ⅰ10, the relative positions of at least two groups of arc rods Ⅰ201 and arc rods Ⅱ202 feed back the relative angles of the monitored components Ⅰ10 and Ⅱ11. At this time, the user can obtain the relative angles of the monitored components Ⅰ10 and Ⅱ11 by observing the relative positions of the two groups of arc rods Ⅰ201 and arc rods Ⅱ202.

[0039] The angle fed back by the relative position of each set of arc rods Ⅰ201 and arc rods Ⅱ202 is a relative angle with a virtual axis perpendicularly passing through the circular surface where the arc telescopic rods 2 are located and the center of the circle as the axis. At this time, the two sets of arc telescopic rods 2 can monitor two relative angles at the same time, thereby providing accurate angle information of the monitored components Ⅰ10 and Ⅱ11.

[0040] The assembled node angle monitoring device provided by the present invention realizes at least two relative angle information through at least two sets of arc-shaped telescopic rods 2, can provide accurate angle monitoring, and the assembled node angle monitoring device can be disassembled and used repeatedly, and is suitable for various assembled building node assembly monitoring. In addition, it has a simple structure and strong practicality, and can significantly improve the efficiency and structural safety of assembled building construction.

[0041] In one preferred embodiment, refer to the attached Figure 2 , the arc-shaped telescopic rods 2 are provided in two groups;

[0042] The arc surfaces of the two groups of arc-shaped telescopic rods 2 are perpendicular and coplanar with the straight rod 1. At this time, the axis position of the straight rod 1 is defined as the z-axis, and the z-axis passes vertically through one group of arc-shaped telescopic rods 2 (attached Figure 2 The virtual axis of the circular surface and the center of the circle where the arc-shaped telescopic rod 2 on the right side of the middle is located is defined as the x-axis, which vertically passes through another set of arc-shaped telescopic rods 2 (attached Figure 2The circular surface where the arc-shaped telescopic rod 2) is located on the left side of the middle and the virtual axis of the center of the circle are defined as the y-axis. At this time, the structure of this assembled joint angle monitoring device can form a standard xyz coordinate axis system, and the monitored member II 11 is consistent with the standard xyz coordinate axis system. In this way, the deflection angles of the monitored member I 10 relative to the x-axis and y-axis in the standard xyz coordinate axis can be monitored, and the relative angle between the monitored member I 10 and the monitored member II 11 can be accurately obtained. In this embodiment, by setting two groups of arc-shaped telescopic rods 2, the relative angles of the monitored member I 10 and the monitored member II 11 on the xyz coordinate axis system can be obtained. Compared with the current single-axis measurement, the monitoring is more accurate, the structure is simpler, and the angle acquisition is more convenient and fast.

[0043] In one embodiment, a hinge seat 3 is hingedly arranged at the outer end of the arc-shaped rod II 202, and the hinge axis of the hinge seat 3 is collinear with the radius of the arc-shaped rod II 202;

[0044] The seat body of the hinge seat 3 is used to be fixed on the monitored member I 10. Preferably, a bolt fastener is arranged on the seat body of the hinge seat 3 for detachably fixing the seat body of the hinge seat 3 on the monitored member I 10;

[0045] The hinge axes of the two groups of hinge seats 3 are vertically intersecting. At this time, the hinge axis of the hinge seat 3 connected to the arc-shaped telescopic rod 2 with the virtual axis as the x-axis is on the y-axis, and the hinge axis of the hinge seat 3 connected to the arc-shaped telescopic rod 2 with the virtual axis as the y-axis is on the x-axis. In this embodiment, the hinge seat 3 restricts the rotation direction of the arc-shaped rod II 202, ensuring that it only expands, contracts and rotates in its defined direction, and improving the measurement accuracy.

[0046] In other embodiments, the outer end of the arc-shaped rod II 202 can be fixed on the monitored member I 10 through a spherical hinge.

[0047] In one embodiment, the arc-shaped rod I 201 is a rod body or a sleeve, the arc-shaped rod II 202 is a sleeve or a rod body, and the rod body is slidably arranged in the sleeve, that is, one of the arc-shaped rod I 201 and the arc-shaped rod II 202 is a sleeve and the other is a rod body, so as to conveniently form the arc-shaped telescopic rod 2 by combination. Preferably, the arc-shaped rod I 201 is a sleeve and the arc-shaped rod II 202 is a rod body, so as to conveniently fix the arc-shaped rod II 202 and the straight rod 1;

[0048] It further includes an angle scale display device provided on the sleeve or the rod body. The angle scale display device is used to feedback the relative positions of the arc rod I 201 and the arc rod II 202 more easily distinguishable. Among them, the angle scale display device can be a measuring scale provided on the sleeve. At this time, the sleeve is made of a transparent material, and the position of the rod body on the measuring scale can be directly observed, so as to quickly and accurately obtain the relative positions of the arc rod I 201 and the arc rod II 202. During use, the angle scale display device can be pre-calibrated to accurately feedback the relative angle of the monitored member I 10 and the monitored member II 11.

[0049] In one preferred embodiment, referring to the attached Figure 3 , the angle scale display device includes a hydraulic cavity 4 formed by enclosing the end of the rod body and the inner periphery of the sleeve. The hydraulic cavity 4 is filled with liquid, and also includes a capillary 5 and a hydraulic rotation scale 6 communicating with the hydraulic cavity 4. When the arc rod I 201 and the arc rod II 202 relatively expand and contract, the capillary 5 transfers the liquid to the hydraulic rotation scale 6 according to the pressure. The hydraulic rotation scale 6 displays the hydraulic pressure as a rotation angle scale reading through the relationship between hydraulic pressure and rotation angle (which can be pre-calibrated). With the change of the relative positions of the arc rod I 201 and the arc rod II 202, the hydraulic pressure in the hydraulic cavity 4 changes, and the liquid enters and exits the hydraulic rotation scale 6 through the capillary 5 to change the value of the hydraulic rotation scale 6.

[0050] In this embodiment, using the hydraulic pressure change to reflect the rotation angle change avoids the use of built-in batteries or external power supplies, making the monitoring device have the characteristics of green low-carbon and high adaptability. The detachable and reusable design of the device enables it to be reused and is suitable for the assembly monitoring of various prefabricated building joints.

[0051] In one embodiment, the straight rod 1 includes a straight rod I 101 and a straight rod II 102 that are telescopically connected to each other, that is, the straight rod 1 can be telescoped, so as to adapt to the change of the relative distance between the monitored member I 10 and the monitored member II 11, and improve the adaptability of this angle monitoring method;

[0052] At this time, the outer end of the arc rod I 201 is fixedly connected to the outer end of the straight rod I 101;

[0053] The outer end of the straight rod II 102 is used to be fixed on the monitored member II 11. Preferably, a fastening plate 1021 is provided at the outer end of the straight rod II 102, and the fastening plate 1021 is used for detachable connection with the monitored member II 11. It should be noted that the outer end of the straight rod I 101 is the end of the straight rod I 101 away from the straight rod II 102, and the outer end of the straight rod II 102 is the end of the straight rod II 102 away from the straight rod I 101.

[0054] In one embodiment, referring to the attached Figure 4A return spring 7 is provided between the straight rod Ⅰ101 and the straight rod Ⅱ102, that is, the straight rod 1 is an elastic telescopic rod, which can ensure the structural stability and compactness of the straight rod 1.

[0055] In one embodiment, the straight rod Ⅰ101 and the straight rod Ⅱ102 are provided with a distance scale display device. In this case, the straight rod 1 can be used to monitor the relative distance between the monitored component Ⅰ10 and the monitored component Ⅱ11, thereby improving the monitoring capability of the assembled node angle monitoring device. Preferably, one of the straight rod Ⅰ101 and the straight rod Ⅱ102 is a straight rod, and the other is a straight tube. The straight rod is slidably sleeved in the straight tube. In this case, the distance scale display device can be a scale set on the wall of the straight tube, and the straight tube is made of transparent material. By observing the position of the straight rod on the scale, the relative distance between the monitored component Ⅰ10 and the monitored component Ⅱ11 can be fed back.

[0066] In a specific embodiment, the assembled joint angle monitoring device of the present invention is used to monitor the splicing of precast components above and below the joint (the monitored member I10 and the monitored member II11 are coplanar).
