[0002] With the development and progress of science and technology, the use of prefabricated buildings is increasing, and prefabricated floor slabs, prefabricated wall panels, prefabricated bridges, etc. are becoming more and more widely used. When prefabricated buildings are produced, embedded sleeves are set inside the prefabricated components to connect the steel bars at the ends of the connected components. The embedded sleeves and steel bars are connected to achieve convenient installation of prefabricated buildings.

[0003] like Figure 1 When the bridge support column (lower member) shown is installed with the upper member, the steel bars and the embedded sleeves need to be aligned during installation. Due to the large number of steel bars and embedded sleeves, the alignment work is laborious and time-consuming, which affects the installation efficiency of the prefabricated building. Therefore, it is necessary to design a guiding and positioning device to improve the assembly efficiency of the prefabricated building.

[0004] For example, the Chinese patent publication number CN114046054A discloses a guiding and positioning device and construction method for assembled building components, which includes a positioning mechanism disposed below the embedded sleeve, which is detachably connected to the upper component through a connecting structure, and a calibration mechanism for pre-positioning the positioning mechanism disposed below the positioning mechanism, which is detachably connected to the upper component.

[0040] The diameter of the upper positioning hole gradually increases from top to bottom, so that the steel bar 2 can be guided through the upper positioning hole and enter the embedded sleeve.

[0041] like Figure 2 , 6 As shown, the connecting seat 7 is an L-shaped plate, and a first connecting block 8 is provided on the bottom surface of the connecting seat 7. An adjusting shaft 9 is rotatably connected to the lower side of the first connecting block 8. An adjusting hole is opened in the middle of the adjusting shaft 9, and the connecting arm 5 is slidably connected to the adjusting hole.

[0042] When the upper positioning part is installed, the connecting arm 5 is fixedly connected to the adjusting hole, and locking bolts should be connected to the adjusting shaft 9 and the first connecting block 8. The first connecting block 8 and the adjusting shaft 9, and the adjusting shaft 9 and the connecting arm 5 are fastened by tightening the locking bolts.

[0043] The inner side of the connecting seat 7 is in contact with the outer side of the upper member 1. Figure 1 In the case of the square column shown, the connection seat 7 is L-shaped. When the upper member 1 is in other shapes, the inner side surface of the connection seat 7 should fit with the corner of the side wall of the upper member 1.

[0044] like Figure 2 , 6 As shown in FIG. 8 , a plurality of telescopic rods 10 are connected to the circumferential direction of the lower positioning portion, and an arc-shaped push piece 11 is connected to the extended end of the telescopic rod 10;

[0049] A winding assembly 13 is connected to the lower side of the lower positioning part, and the lower end of the positioning rope 3 is connected to the winding assembly 13. The winding assembly 13 includes a winding motor and a winding roller. The output shaft of the winding motor is fixedly connected to one end of the winding roller, and the positioning rope 3 is connected to the winding roller.

[0050] The slider is in smooth contact with the annular adjustment groove 6. The axial direction of the winding roller is perpendicular to the length direction of the positioning rope 3, and the output shaft of the winding motor can be fixedly connected to the winding roller, or the winding roller can be driven to rotate by gear meshing.

[0051] like Figure 2 , 9 As shown, a longitudinal connecting channel 14 is provided inside the lower positioning plate, and the connecting channel 14 is used to accommodate the positioning rope 3. A plurality of pressure sensors are provided on the inner side of the upper end of the connecting channel 14, and the plurality of pressure sensors are arranged along the circumferential direction of the connecting channel 14. The detection end of the pressure sensor is connected to a detection plate 15, and the detection plate 15 is arranged adjacent to the positioning rope 3.

[0052] When the detection plate 15 is pressed, the detection plate 15 tilts toward the pressure sensor, so that the pressure sensor is pressed and transmits the pressure signal to the controller.

[0053] like Figure 5 As shown, an indication module 16 is provided on the upper side of the lower positioning plate, and the interior of the knowledge module is provided with indicator lights of the same number as the detection board 15 , and the arrow directions of several indicator lights correspond one-to-one to the installation direction of the detection board 15 relative to the positioning rope 3 .

[0054] The controller controls the indicator light in the opposite direction to light up according to the signal transmitted by the pressure sensor, reminding the staff that the upper component 1 should be moved in the opposite direction of the pressure sensor, so that the upper component 1 is adjusted to a vertical state, and the positioning rope 3 is vertically connected between the upper positioning part and the lower positioning part.

[0055] like Figure 2 As shown, at least two horizontal connection screw holes are arranged inside the connection seat 7, and a long screw rod 17 is connected between two adjacent connection seats 7.

[0056] Two adjacent connection seats 7 are connected by a connection screw, and the ends of the connection screw are fixed by nuts so that the two connection seats 7 are relatively embraced at the lower part of the upper component 1.

[0057] The present solution also includes a controller, the position of which is set by the staff according to actual conditions during operation. The controller is used to control the electrical devices used in the present solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication equipment, lights, speakers and microphones; the controller is an Intel processor, an AMD processor, a PLC controller, an ARM processor or a single-chip microcomputer, and the supporting motherboard, memory stick, storage medium and power supply are also included therewith, and the power supply is AC or a lithium battery; for the operating principle of the controller, please refer to "Principles of Automatic Control", "Principles of Microcontrollers and Application Simulation Cases" and "Principles and Applications of Sensors", and other books in the field can be used for reference; other automatic controls and electrical devices not mentioned are all knowledge well known to those skilled in the art and will not be repeated here.

[0058] The steps include:

[0059] S1. Installation: Install two connection seats 7 at the lower part of the side elevation of the upper member 1, connect the lower positioning portion to the upper portion of the steel bar 2, and install the upper positioning portion at the bottom of the embedded sleeve of the upper member 1;

[0060] The number of guide and positioning devices used in the present application is at least 2, and the two guide and positioning devices are installed at both ends of the same side elevation of the upper member 1, such as Figure 2 As shown, the embedded sleeves and steel bars 2 at both ends of the same row or the same column are guided and positioned;

[0061] Or two guiding and positioning devices are arranged along the diagonal of the upper component 1, and the upper positioning part and the lower positioning part are installed on the lower side of the two embedded sleeves at both ends of the diagonal. When the two embedded sleeves and the steel bars 2 at both ends of the diagonal are guided and positioned, the guiding and positioning parts need to be connected with the help of an additional connecting seat 7.

[0062] When installing the upper positioning part, first insert the positioning rod with the same diameter as the steel bar 2 into the embedded sleeve. Figure 4 As shown, the two upper positioning seats 4 are connected under the positioning of the positioning rod, and the connecting arm 5 is connected and fastened to the adjustment shaft 9. After the installation is completed, the positioning rod can be removed.

[0063] S2. Adjustment: Adjust the positioning rope 3 so that the length of the positioning rope 3 between the lower positioning portion and the upper positioning portion is equal;

[0064] S3. Installation: The upper member 1 is lowered, and the upper member 1 pushes the upper positioning portion and the lower positioning portion downward along the steel bar 2 until the upper end of the steel bar 2 is inserted into the upper member 1 embedded sleeve;

[0065] S4. Disassembly: Remove the connection seat 7, the upper positioning part and the lower positioning part to completely connect the upper member 1 with the steel bars 2 of the lower member.

[0066] When the steel bar 2 is not completely inserted into the embedded sleeve, the two upper positioning seats 4 and the two lower positioning seats 12 are disassembled, the long screw rod 17 is removed, and the guide positioning device is removed to make the upper component 1 and the lower component tightly connected.

[0067] After the upper positioning part and the lower positioning part are installed, the positioning rope 3 is tightened by the winding motor so that the multiple positioning ropes 3 are arranged in parallel. The specific adjustment principle is as follows:

[0068] After the upper positioning part and the lower positioning part are installed, the slider slides along the inside of the annular adjustment groove 6. When the winding motor is running, the positioning rope 3 is tightened. At the same time, the rotation of the winding roller is detected by the Hall sensor, so that the positioning rope 3 is wound up the same number of turns until the extended lengths of multiple positioning ropes 3 are equal.

[0069] When the positioning rope 3 is tightened, if the positioning rope 3 is in a vertical state, the positioning rope 3 will not cause backlog on the detection plate 15, and the upper member 1 can be moved downward, so that the steel bar 2 is guided through the upper positioning hole and enters the embedded sleeve;

[0070] When the positioning rope 3 is tightened, if the positioning rope 3 is in an inclined state, the positioning rope 3 will cause a backlog on a certain detection plate 15, and the pressure sensors in the connecting channel 14 will be numbered. When the corresponding pressure sensor is pressurized, the controller controls the arrow in the opposite direction of the indicator module 16 to light up according to the direction of the pressure sensor that sends the pressure signal, prompting the staff to adjust the angle of the upper component 1 to tilt the upper component 1 away from the pressurized pressure sensor until all the pressure sensors are not pressurized, indicating that the positioning rope 3 is in a vertical state. The positioning rope 3 and the connecting channel 14 are coaxially arranged, so the upper component can be downward to allow the steel bar 2 to enter the embedded sleeve through the upper positioning hole.

[0071] The application is equally applicable to building guide work for lateral or inclined assembly.
