[0072] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0073] According to the structural characteristics of the assembled box-plate steel structure building and the length of the shear wall panel, the number and layout of the positioning blocks on the floor are set, and the positioning blocks with touch alarms are spot welded at the appropriate positions of the floor. The shear wall panel is hoisted by the lifting equipment to the vicinity of the installation position. When the shear wall panel reaches the specified position, it touches the touch alarm system of the floor positioning block and sends out an alarm signal. The alarm signal is divided into a single alarm and multiple alarms that meet the requirements at the same time. The operator can determine the positioning and alignment work of the point according to the alarm signal; after completing the alignment of the shear wall panel and the floor, the bottom of the shear wall panel is spot welded. The shear wall panels are connected to the floor slabs through a new adjustable supporting device, and the verticality of the shear wall panels is adjusted to within the allowable deviation of accuracy by rotating the tensioning head; during the adjustment process, the operator can observe the vertical state of the shear wall panels through a new vertical detection device; when the verticality of the shear wall panels is adjusted, the shear wall panels and the surrounding structures are fixed by spot welding, and the upper shear wall panels are clamped and fixed to adjacent shear wall panels or columns and other components through the shear wall panel clamping device to prevent the upper shear wall panels from deforming in a free state, and then the subsequent shear wall panel welding work is completed according to the conventional construction sequence.

[0074] The positioning alarm device consists of a positioning block and a touch alarm. Due to the structural characteristics of the prefabricated box-plate steel structure building, the alignment and verticality of the shear wall panels are the difficulties and key points of manufacturing. The number and layout of the positioning blocks on the floor are set according to the length of the shear wall panels, and the positioning blocks with touch alarms are spot welded to the floor; the touch alarm is installed on the positioning block and the touch point is on the positioning working surface of the positioning block. The touch alarm signal is divided into a single alarm and an alarm that meets the requirements at the same time. At the same time, the duration of the alarm signal design should try to meet the spot welding work of the floor and the shear wall panels to detect the alignment quality of the spot welding.

[0075] The adjustable support device consists of a tensioning rod and two movable arms, the tensioning rod is connected to the two movable arms through a hinge point, and the two movable arms are also connected through a hinge point. By adjusting the tensioning rod, the angle of the two movable arms can be changed to achieve the adjustment effect; the tensioning head on the tensioning rod device is provided with a protective cover to prevent dust or iron filings splashed by welding from damaging the screw thread; a dial is provided at the connection hinge of the movable arm, and the dial is welded to one of the movable arms. When the distance between the two support points and the length of the two movable arms are known, the two movable arms can be roughly adjusted with the help of the data on the dial before use, which can save the time of cyclic detection during blind adjustment. The upper arm can be pushed and pulled during load adjustment. This operation plays an auxiliary role in the adjustment and can save the rotational adjustment force at the tensioning head. It is suitable for the support adjustment of the large-area but light-weight single-piece reinforced steel plate shear wall panel in the assembled box plate steel structure building.

[0076] The vertical detection device consists of a laser projection device and a prism reflection device.

[0077] The laser projection device consists of a magnetic base Ⅰ, a circular dial, a locking nut Ⅰ, a wear-resistant sleeve, a locking nut Ⅱ, a connecting column, a mounting plate Ⅰ, a universal wheel, a universal level bubble Ⅰ, a connecting hinge shaft and fastening standard parts, a mounting plate Ⅱ, and a high-precision laser transmitter; the center of the circular dial is provided with an inner hole matching the magnetic base Ⅰ, which is fixed to the magnetic base Ⅰ through a connecting column and a locking nut Ⅰ, and the scale lines are arranged around the center; the mounting plate Ⅰ is provided with a wear-resistant sleeve mounting hole Ⅰ, a universal wheel mounting hole Ⅱ and a center hinge point hole Ⅲ, and the pointer and the circular dial are vertically welded, and the scale values ​​on the circular dial are arranged around the center hinge point hole Ⅲ; when the high-precision laser transmitter is installed, the laser emission point It must pass vertically through the center of the center hinge hole III so that the pointer on the dial can accurately reflect the rotation angle of the laser transmitter. It is installed on the mounting plate II with a pointer and fixed to the mounting plate I by connecting the hinge shaft and fastening standard parts; the universal level bubble I is fixed on the mounting plate I to ensure that one of the cross lines of the universal level bubble I must pass vertically through the center hinge hole III; the mounting plate I is installed to the connecting column with a wear-resistant sleeve and a universal wheel, and the universal wheel is adjusted to the dial on the magnetic seat I through the universal level bubble I to ensure that the supporting connecting plate I remains parallel to the magnetic seat and is fixed by the locking nut II thereon. At this time, the assembly of the vertical detection device is completed. The connecting plate Ⅰ with a pointer can rotate around the connecting column, and the universal wheel can support the connecting plate Ⅰ to maintain balance. In conjunction with the circular dial indication on the magnetic base Ⅰ, it can achieve 360° rotation and reading centered on the engagement hole of the magnetic base Ⅰ; the mounting plate Ⅱ with a pointer can rotate around the central hinge hole Ⅲ of the connecting plate Ⅰ. In conjunction with the dial on the mounting plate Ⅰ, it can achieve 360° rotation and reading centered on the central hinge hole. This device is a universal laser transmitting device.

[0078] The prism reflection device consists of a laser target Ⅰ, a prism seat Ⅰ, a universal level bubble Ⅱ, a laser target Ⅱ, a right-angle prism Ⅰ, a cylinder cover, a handle standard part Ⅰ, a cylinder body, a right-angle prism Ⅱ, a prism seat Ⅱ, a handle standard part Ⅱ, a support adjustment device, a locking nut, a universal foot bolt, and a magnetic seat Ⅱ. The cylinder is the main connecting component of the whole device. The design of this component must meet the observation requirements. The cylinder and the emission line of the internal laser can be designed according to the on-site conditions. Positioning grooves are provided at both ends of the cylinder on the same vertical line. The positioning grooves match the positioning blocks on the cylinder cover and the prism seat II. The positioning line is the reference positioning benchmark for the laser entrance hole, laser target I, prism seat I, laser emission port, laser target II and other parts involved in prism reflection on the cylinder cover. After completing the positioning assembly, a calibration is performed to ensure that when the laser enters the device vertically from the center of laser target I, it can be reflected according to the designed path and pass through the center of laser target II as required by theory. After the calibration is qualified, the cylinder cover is fixed with the standard part I, the prism seat II is fixed with the standard part II, and the universal level bubble is installed on the cylinder cover to complete the assembly of the main structure of the prism reflection device. One end of the universal foot bolt connects the support adjustment device with a locking nut to the magnetic seat II and fixes it through the locking nut, and the other end is connected to the prism seat II and fixed, thereby completing the assembly of the prism reflection device. The device has the function of self-adjusting the level. When the flatness of the installation surface is poor, the locking nut at the support adjustment device can be adjusted by observing the universal level bubble on the upper part of the cylinder to make the device reach a horizontal state.

[0079] After the bottom of the shear wall panel is positioned and aligned with the floor, the laser projection device is fixed to the shear wall panel through the magnetic seat I, and the universal level bubble I and II are checked for offset. The laser line is adjusted to be perpendicular to the floor and parallel to the shear wall panel by adjusting the universal wheel. The laser point on the floor and the parallel distance of the laser line to the shear wall panel are passed. The prism reflection device is placed and fixed to the floor through the magnetic seat II. If the universal level bubble II of the prism reflection device is offset at this time, it means that there is a local deviation in the floor where the magnetic seat is placed. The horizontal and vertical laser detection experiments are achieved by adjusting the support adjustment device. After passing the test, the alignment of the laser projection device and the prism reflection device is completed; during the vertical adjustment of the shear wall panel, the shear wall panel makes axial swinging motion around the intersection line with the floor slab. According to the arrangement of the prism reflection lines and observation holes in various places in the prism reflection device during the design process, during the adjustment process, as long as the light passes through the center of the laser target II at the exit of the tube cover, the shear wall panel and the floor slab are in a vertical state. This method can avoid the problem of the outdoor light being too strong or too weak to see the laser line in actual work, and accurately complete the vertical detection work during the adjustment of the shear wall panel and the floor slab.

[0080] The structural form of the shear wall panel clamping device is determined by the installation node and the form of the panels. The outer fixing frame, the inner fixing frame and the upper cover plate are welded to form an inserted three-sided structure. The inner fixing frame has a threaded hole for the top screw, and the outer fixing frame is provided with a thickness adjustment pad of the same thickness as the weld pad. The top screw is used to clamp the outer fixing frame adjustment pad and the workpiece to achieve the purpose of maintaining the shape.

[0085] Example:

[0086] like Figure 1 , 2 As shown, a method for positioning and installing a stiffened steel plate shear wall panel in a prefabricated box plate steel structure building includes a positioning alarm device, an adjustable support device, a vertical detection device, and a shear wall panel clamping device. The specific steps are as follows:

[0087] Step 1: Select appropriate components according to the on-site conditions, and complete the assembly and positioning of the positioning alarm device 2, and the assembly of the adjustable support device 3, the laser projection device 401 and the prism reflection device 402.

[0088] Step 2: The lifting equipment hoists the shear wall panel to the installation site. When the shear wall panel touches the touch sensor 204 at a single point, a single alarm is issued. The position of the shear wall panel is adjusted to achieve simultaneous alarms at each positioning point. The bottom of the shear wall panel and the floor slab are spot welded, and the adjustable support device 3 is connected to the shear wall panel and the floor slab through the connection standard part Ⅰ305.

[0089] Step three, fix the laser projection device 401 to the appropriate position of the shear wall panel through the magnetic base I 401-1, and check the contact with the shear wall panel through the universal level bubble I 401-9. If the mounting plate I 401-7 has a dimensional deviation after the magnetic base I 402-1 is fixed due to local deviation of the shear wall panel, the universal wheel 401-8 can be adjusted to make the laser line parallel to the shear wall panel surface and perpendicular to the floor surface.

[0090] Step 4, turn on the high-precision laser transmitter 401-12 in the laser line projection device 401, and place the prism reflection device 402 according to the distance from the laser emission point in the laser line projection device 401 to the shear wall and the laser point on the floor, and fix it to the floor through the magnetic seat II 402-15. If the cylinder 402-8 has dimensional deviation after the magnetic seat II 402-15 is closed due to local deviation of the floor, it can be observed and adjusted through the universal level bubble II 402-3, universal foot bolts 402-14 and support adjustment device 402-13. After passing the verification, the alignment work of the laser line projection device 401 and the prism reflection device 402 is completed.

[0091] Step 5: Hold the handle of the tensioning head 302-2 in the adjustable support device 3 and turn it. The operator can check whether it is vertical through the vertical detection device 4. When the laser line is emitted at the center of the laser target II 402-4 of the prism reflection device 402, the shear wall panel reaches a vertical state.

[0092] Step 5: Fix the shear wall panel to the surrounding structure by spot welding, and install the shear wall panel clamping device 1 on the upper part. Place the upper cover plate 101 on the upper end surface of the shear wall panel, and place the adjustment pad 103 welded on the outer fixing frame 102 close to the outer shear wall panel. Install the top screw 105 on the inner fixing frame 104 to clamp the upper part of the shear wall panel.

[0093] Step six, based on the above steps, formally weld the shear wall panels to complete the positioning and installation of the shear wall panels with high precision.
