Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to a multifunctional wall tie for building scaffolding and its construction method, applicable to the most common type of steel pipe scaffolding with couplers on construction sites. Background Technology

[0002] During the structural construction of the main building, external scaffolding must be erected according to the building's floor height to facilitate worker operations and ensure the safety of the entire building facade. The connection between the external scaffolding and the building structure typically involves pre-embedding short vertical steel pipes (48mm in diameter, 3mm in wall thickness) during the pouring of concrete floor slabs. After the concrete has set, a horizontal standard steel pipe is used to secure the scaffolding members to the pre-embedded short vertical steel pipes using fasteners, thus connecting the scaffolding to the building and achieving stability. National standards require that all scaffolding connection points to the main structure be installed along the vertical direction at every floor, and horizontally at every 4.5m. Therefore, a large number of wall ties are required throughout the entire building facade.

[0003] The construction and installation of this traditional wall tie has the following significant drawbacks:

[0004] 1. Defect of limited functionality

[0005] Traditional wall ties only have a unidirectional connection function and cannot simultaneously meet the complex functional requirements of vertical load transfer of scaffolding, landing of new drones, installation of safety warning signs, and strengthening of safety measures, resulting in the need to add a variety of auxiliary components on site.

[0006] 2. Non-recyclability of embedded parts

[0007] The pre-embedded vertical short steel pipes need to be pre-embedded into the concrete structure layer by layer as the construction progresses. They need to be removed later by cutting and destroying them, resulting in a one-time loss rate of more than 90% of the steel and causing serious waste of resources.

[0008] 3. Process conflicts and difficulties in resuming operations may lead to violations of operating procedures.

[0009] When the installation of building components (such as window frames or railings) requires the temporary removal of wall ties, traditional pre-embedded wall ties need to be loosened by scaffolders using a special torque wrench. After the installation is completed, the ties need to be tightened again using the same wrench. Workers installing window frames or railings, in order to meet deadlines or due to a lack of tools, often choose to "remove without restoring" or "virtually hang steel pipes to pass inspections," leaving the scaffolding unsupported and causing safety accidents.

[0010] 4. Hidden defects are difficult to detect.

[0011] After traditional wall ties are removed, their missing status is not visually indicated or electronically recorded, requiring safety personnel to manually check each floor. Statistics show that approximately 40% of missing wall ties go undetected due to their concealed nature, creating a "management blind spot."

[0012] The installation of wall ties at window openings and balcony curbs is inconvenient and poses many potential quality risks.

[0013] Traditional clamping methods for wall ties at window openings require fasteners to clamp the window frame. Applying pressure exceeding 10kN can easily deform the PVC window frame, and the conflict rate between the pre-embedded short steel pipe and the window frame anchor bolts reaches 30%, leading to chiseling and rework. At the balcony curb, the anchoring depth of the pre-embedded short steel pipe in the wall ties is only 60-80mm (the specification requires ≥120mm), resulting in insufficient pull-out resistance, reaching only 55% of the design value. Removing the pre-embedded parts and sealing the openings can easily create micro-cracks, increasing the probability of rainwater infiltration by four times compared to a completely intact structure.

[0014] To address the aforementioned issues, the present invention urgently needs to solve the problem of developing a wall-connecting component that possesses multiple functions, is reusable, easy to dismantle and restore, can promptly detect the working status of the wall-connecting component through a signal terminal, and can adapt to multiple scenarios. Summary of the Invention

[0015] Based on the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a multifunctional wall tie for building scaffolding and its construction method, which solves the problems of the traditional wall tie for scaffolding having a single function, non-recyclable embedded parts, difficulty in restoring process conflicts, difficulty in investigating hidden defects, and inconvenience in setting up wall ties at window openings and balcony curbs.

[0016] To achieve the above objectives, the present invention employs the following technical measures:

[0017] This invention relates to a multifunctional wall tie for building scaffolding, comprising an outer sleeve, an inner insert rod, an outer turntable, an inner turntable, a support sleeve, a signal transmitting unit, a signal receiver, a hook, a warning tape insert, and a stop platform. Both the outer sleeve and the inner insert rod are threaded metal cylindrical rods at one end. The inner insert rod can slide and extend within the outer sleeve. The position of the inner insert rod and the outer sleeve can be adjusted and locked by inserting the hook into pre-set holes in the outer sleeve and the inner insert rod. The outer turntable is mounted on the threaded end of the outer sleeve, and its position on the threaded end of the outer sleeve can be adjusted by rotation. The inner insert rod has an inner turntable mounted on its threaded end. The inner turntable can be rotated to adjust its position on the threaded end of the inner insert rod. A support sleeve is sandwiched between the outer and inner turntables, and a signal transmitting unit is provided in the inner cavity of the support sleeve. The support sleeve can fix the distance between the outer and inner turntables. The inner cylinder of the non-threaded end of the outer rod can be inserted into the plug-in rod of the stop platform. The position of the stop platform at the outer end of the outer rod can be fixed by inserting the warning tape insert into the through hole reserved between the non-threaded end of the outer rod and the plug-in rod of the stop platform.

[0018] Preferably, the outer sleeve rod has a first threaded connection at one end of the rod body along the axial direction, and a plurality of positioning through holes are arranged at equal intervals along the axial direction of the outer sleeve rod. A fixing through hole is provided at the end of the rod body away from the first threaded connection.

[0019] Furthermore, the inner insert rod has a second threaded connection at one end of its axial direction, and multiple sets of adjusting through holes are continuously arranged at equal intervals along the axial direction of the inner insert rod.

The first rotating part includes three sets of force transmission components symmetrically distributed at 120°. Each set of force transmission components consists of a square cross-section connecting rod and a first torsion cylinder.

[0021] Preferably, the structure of the inner turntable is the same as that of the outer turntable, and the inner diameter of the second central shaft cylinder of the inner turntable is provided with an M42×3 internal thread section to adapt to the second threaded connection part of the inner insert rod.

[0022] Furthermore, the support sleeve consists of a support plate, a sleeve body, and a handle. The support plate is made of two steel plates welded to the sleeve body. The support plate has a semi-circular track cross-section shape. The straight section of the support plate is provided with 6 axially parallel pads, and the annular section is provided with 6 radial pads, all of which are phase-shifted with the friction pins of the inner and outer turntables to form an interlaced anti-slip engagement interface. The sleeve body has a semi-circular track cross-section and is coplanarly spliced ​​with the inner ring and straight section of the support plate. The handle is cylindrical and located between the tops of the two support plates.

[0023] Preferably, the signal transmitting unit is housed in a mounting cavity of a support plate near the outer turntable side, and includes a battery, a button cap, a cylindrical helical spring, a positive electrode guide plate, a negative electrode dual lever guide plate, a first circuit main board, a radio frequency transmitting circuit, a signal indicator light, and an encoding chip. A mounting cavity for placing the signal transmitting unit is provided within the support plate near the outer turntable side, and an insulating coating is provided on the inner wall of the cavity. The battery cavity is located at the bottom, the spring cavity at the front end of the battery cavity, and the chip cavity at the top of the battery cavity. A signal antenna protrusion hole and an indicator light protrusion hole are provided at the top of the support plate. A limiting hole for the trigger button cap is provided near the outer turntable on the support plate, and a battery replacement hole is provided far from the outer turntable on the support plate. The battery is installed in the battery cavity, and the button cap protrudes through the limiting hole. The annular boss on the outer edge of the button cap forms an axial limit with the limiting hole. The rear part of the button cap... The metal ejector pin is connected to the cavity limiting baffle via a cylindrical helical spring; the positive electrode guide plate is formed by bending phosphor bronze sheet into a cantilever beam structure, with its upper end welded and fixed to the lower part of the first circuit board, and its lower free end located in the middle gap between the positive terminal of the battery and the end of the metal ejector pin; when the button cap is triggered, the positive electrode guide plate contacts the positive terminal of the battery under the pressure of the end of the metal ejector pin to achieve power supply; the metal contact at the end of the lower lever of the negative electrode double lever guide plate is in long-term contact with the negative terminal of the battery; the negative electrode double lever guide plate opens under external force and resets under the action of elastic reset force; the first circuit board is located at the upper end of the battery, with the radio frequency transmitting circuit and signal indicator light welded to its upper part, and the encoding chip welded to its middle part; the fixed ends of the positive electrode guide plate and the negative electrode double lever guide plate are welded to its lower part.

[0024] Furthermore, the signal receiver includes a housing, a panel, a second circuit board, a signal receiving antenna, a signal conversion chip, a power LED, a battery compartment, and LED array pads. The top surface of the housing is fitted with a panel, which has light-transmitting holes corresponding to the LED beads on the 36 LED array pads and one power LED. The bottom surface of the panel is made of composite aluminum grid plate, and the second circuit board is fixed to the bottom of the housing. The front section of the second circuit board is used to solder the base of the signal receiving antenna, the front section is used to mount the packaged signal conversion chip, the middle section is used to install the power LED, the rear section is used to install the battery compartment, and the two side sections are used to install the 36 LED array pads. The signal receiving antenna is a copper alloy rod antenna with a top loop coil at the top.

[0025] Furthermore, the hook is divided into two components: a first insert rod and a hook body. There are two hook bodies, symmetrically welded to the top two sides of the first insert rod. The warning tape insert includes a second insert rod, a support plate, a shaft, and a pull rod. The top section of the second insert rod is fixed at the geometric center point of the bottom of the support plate. The shaft is fixed to the top of the support plate and includes a shaft housing, a central rotating shaft, a spiral spring, a guide roller, and a warning tape. The shaft housing has an arc-shaped notch in a horizontal view, and rectangular windows are provided on the sidewalls of the shaft housing at locations symmetrically distributed with the arc-shaped notch. A webbing locking buckle is provided on the inner side of the pull rod to secure one side of the warning tape. The pull rod pulls the warning tape out through the rectangular window, and the spiral spring accumulates torque. When the tension is released, the spiral spring drives the central rotating shaft to rotate, and the warning tape is smoothly wound around the guide roller. When the warning tape is completely retracted, the pull rod touches the rectangular window to stop.

[0026] Accordingly, the present invention also provides a construction method for a multifunctional wall tie for building scaffolding, the steps of which are as follows:

[0027] S1: Draw a plan of scaffolding wall tie erection based on the building's facade features and floor plan, and indicate the locations where wall ties need to be installed, numbering them in a certain order.

[0028] S2: When the external scaffolding is erected to the second floor and the wall ties are ready for installation, the worker first rotates the first disc of the outer turntable so that it faces the building and is installed with the first threaded connection of the outer sleeve rod. Then, the inner insert rod is inserted into the outer sleeve rod from the side closest to the first threaded connection of the outer sleeve rod, with the second threaded connection of the inner insert rod on the same side as the first threaded connection of the outer sleeve rod. Next, the positions of the outer sleeve rod and the inner insert rod are adjusted according to the thickness of the building wall or balcony curb. If the structural thickness is 200mm, the distance between the end of the first threaded connection of the outer sleeve rod and the smooth pipe section clamped by the second threaded connection of the inner insert rod is controlled at 200mm, and the positioning through hole and the adjustment through hole are aligned. Finally, two hooks are inserted into the two nearest and adjacent positioning through holes of the first threaded connection of the outer sleeve rod to lock the positions of the outer sleeve rod and the inner insert rod.

[0029] S3: After adjusting the assembly of the outer rod and the inner rod, use two right-angle fasteners to adjust and fix the assembly to the positioned outer frame upright; the height of the assembly of the outer rod and the inner rod is higher than the height of the anti-sill part, and in the plane position, the smooth pipe section clamped by the outer rod and the inner rod is exactly adjusted to be directly above the anti-sill part;

[0030] S4: First, the worker holds the first rotating part of the outer turntable and rotates it to adjust the position of the first disc body so that the first friction pin of the first disc body contacts the side of the anti-slip part; then, the worker holds the second rotating part of the inner turntable and screws the inner turntable into the inner insert rod through the second threaded connection part of the inner insert rod; next, the support sleeve with the designated numbered signal transmitting unit installed is placed into the smooth tube section sandwiched between the outer and inner turntables, the support plate with the signal transmitting unit installed faces the outer turntable side, and the numbered indicator sticker is affixed to the support sleeve;

[0031] S5: The worker holds the second rotating part of the inner turntable and rotates it clockwise. The inner turntable screws into the other side of the anti-slip part along the second threaded connection of the inner insert rod. When the worker feels that rotating the second rotating part is difficult, a steel pipe is inserted into a second torque cylinder and turned clockwise to lock the inner and outer sides of the anti-slip part with the disc bodies of the inner and outer turntables. At the same time, when the disc bodies of the inner and outer turntables compress the support sleeve, the button end cap is gradually squeezed, and the metal pin at its rear is gradually... The gap between the positive electrode guide plate and the positive electrode of the battery is squeezed together. As the inner and outer turntables lock the inner and outer sides of the anti-slip part, the metal pin at the rear of the button cap squeezes the positive electrode guide plate to make contact with the positive electrode of the battery and energize it. The signal indicator light then lights up, indicating that the inner and outer turntables have locked the structure and the wall connector is firmly connected to the structure. At the same time, the external exposed wire is energized and emits radio electromagnetic waves, dispersing the 2.4GHz wireless signal with the digital code of the wall connector chip number.

[0032] S6: In building locations where it is convenient to install ordinary wall ties, steel pipes are pre-embedded at the edge of the floor slab. The pre-embedded steel pipes are vertical. Then, a straight sleeve is rotated and fitted onto the second threaded connection of the inner insert rod. The inside of the straight sleeve is threaded, and the thread size matches the thread of the second threaded connection of the inner insert rod. Finally, the worker uses three right-angle fasteners to connect and lock the outer sleeve, the two outer scaffold uprights, and the straight sleeve.

[0033] S7: In window openings where it is difficult to install ordinary wall ties, firstly, after adjusting the assembly of the outer sleeve rod and inner insert rod, use two right-angle fasteners to adjust and fix the assembly to the positioned external scaffold upright; the assembly of the outer sleeve rod and inner insert rod should be higher than the windowsill of the window opening; in terms of plane position, the smooth pipe section clamped by the outer sleeve rod and inner insert rod should be precisely positioned above the windowsill of the window opening; then, the worker holds the first rotating part of the outer turntable and rotates it, adjusting the position of the first turntable so that the first friction pin of the first turntable contacts the outer edge of the window opening; next, the worker holds the second rotating part of the inner turntable and screws the inner turntable into the inner insert rod through the second threaded connection part of the inner insert rod; then, the installed finger... The support sleeve of the numbered signal transmitting unit is placed into the smooth tube section sandwiched between the outer and inner turntables. The support plate of the signal transmitting unit is installed facing the outer turntable, and a numbered sticker is affixed to the support sleeve. Finally, the worker uses force to lock the inner and outer sides of the window opening with the discs of the inner and outer turntables. The metal pin at the rear of the button cap presses the positive electrode guide plate to make contact with the positive electrode of the battery to conduct electricity. The signal indicator light then lights up, indicating that the discs of the inner and outer turntables have locked the window opening and the wall connector is firmly connected to the structure. At the same time, the external open wire emits radio electromagnetic waves, dispersing the 2.4GHz wireless signal with the digital code of the wall connector chip number.

[0034] S8: After the wall ties and the main building structure are locked, the signal transmitting units are powered on, the signal indicator lights up, and the external exposed wires emit radio electromagnetic waves. The site safety officer holds the signal receiver and powers it on. The power LED of the signal receiver lights up, and the signal conversion chip built into the signal receiver identifies the multiple 2.4GHz wireless signals with digital codes. A certain LED on the LED array pad corresponding to each code lights up. For a failed wall tie, after locking the location, it is directly inspected and the wall tie is reinforced a second time.

[0035] S9: After completing the installation and fastening of the scaffolding, workers need to install a safety net every three floors in the gap between the outer scaffolding and the main building. The insertion position of the hook is exactly within the positioning through hole range of the outer and inner rods in the gap between the outer scaffolding and the main building. The two hooks of the hook hook onto the holes on the perforated tape to connect multiple wall ties in pairs. Finally, the workers install the safety net, with the open part in the middle placed directly above the perforated tape. When building materials and construction waste fall from the floor, the safety net, reinforced by the taut perforated tape, intercepts the falling debris.

[0036] S10: After the external scaffolding is erected, a facade safety net is installed on the outside of the scaffolding to completely enclose the external scaffolding; workers insert warning tape inserts into the fixing holes of the outer sleeves of each wall tie; then, workers pull out the tie rods on each sleeve, and the warning tape fixed to the back of the tie rod is pulled out; next, workers hold the tie rod and move it towards the next warning tape insert, inserting it from top to bottom into the arc-shaped notch in the sleeve shell of the previous warning tape insert to horizontally fix the tie rod; the warning tape behind the tie rod... The warning tape maintains a vertically taut and open state under the interaction of the horizontal fixing force on the tie rod and the rotational force of the central rotating shaft inside the shaft tube within the arc-shaped notch. The tie rod of each warning tape insert is fixed to the arc-shaped notch in the outer shell of the shaft tube of the previous warning tape insert. If the warning tape at the corner of the external scaffold is to be tensioned, it is achieved by bending it 90° using the external scaffold uprights at the corner as corner supports. The warning tape achieves a closed loop state with the entire layer connected end to end.

[0037] Based on the above, the beneficial effects of the multifunctional wall tie for building scaffolding and its construction method of the present invention are as follows:

[0038] 1. Multifunctional integrated design

[0039] Expanded Functionality: Breaking through the traditional single-connection function of wall ties, it integrates four major functional modules: drone landing pad (capable of supporting 25kg drones), safety warning tape anchor point (automatic retraction warning tape), safety net reinforcement node (hook connection of high-strength perforated tape), and electronic monitoring terminal carrier (built-in signal transmission unit).

[0040] 2. Intelligent Status Monitoring System

[0041] The support sleeve incorporates a built-in mechanical-electronic linkage device (button cap + metal pin + guide plate), which automatically activates the circuit when the turntable locks in place and the pressure is ≥0.8N. It transmits encrypted UUID signals (128-bit encoding, including area code + device ID) in real time, broadcasting the wall-mounted fastening status via a RF module (2.4GHz). Visualized security monitoring: The signal receiver displays the status of each location using a 36-channel LED array (divided into left and right zones, corresponding to floor numbers); no lights indicate a failure. This increases the efficiency of security personnel's patrols by 80% and eliminates 40% of traditional blind spots and hidden defects.

[0042] 3. Non-destructive and recyclable installation system

[0043] Pre-embedded clamping technology: Adopting a double-turntable adaptive locking structure (outer / inner turntable + support sleeve), the elastic support plate is compressed by screwing in the thread to achieve rigid anchoring of walls of different thicknesses (window sill / buttress / floor edge).

[0044] Enhanced pull-out resistance: The rotary friction pin adopts an asymmetrical wedge surface design (tightening torque 120 N·m > loosening torque 40 N·m), ensuring that the pull-out resistance reaches 100% of the design value after tightening.

[0045] 100% material recycling rate: All steel components (outer rod, inner rod, turntable, etc.) can be disassembled and reused, solving the problem of 90% loss in traditional pre-embedded short steel pipes.

[0046] 4. Resolution and rapid recovery of process conflicts

[0047] Window frame / railing installation friendliness: Temporary removal only requires rotating the inner turntable to release the clamping force, and after installation, tighten it again until the indicator light illuminates to restore functionality. This avoids the risks associated with traditional fastener disassembly, which requires a special wrench and workers may have to loosely hang steel pipes to pass inspections.

[0048] 5. High-reliability anchoring in special locations

[0049] Thin-walled reinforcement solution for the anti-recess: The contact surface between the turntable and the anti-recess is increased by the interlocking friction pins to increase the friction coefficient, compensating for the insufficient pre-embedded depth of traditional methods (only 60-80mm). Zero-damage installation of window openings: The turntable directly clamps the concrete window sill (not the window frame), eliminating 30% of the anchor bolt conflict rate and eliminating the need for chiseling and rework.

[0050] 6. Enhanced construction efficiency and safety

[0051] High efficiency of telescopic adjustment: The outer rod and inner rod can achieve continuous telescopic extension of 800mm through multi-level adjustment through holes (50mm spacing) to adapt to different structural distances.

[0052] Safety net impact resistance upgrade: The hooks connect to the perforated strip to form a tensioned network, which improves tensile strength and enhances the ability to intercept falling objects from high places.

[0053] Warning tape closed-loop system: The warning tape insert sleeve spiral spring (rebound angular velocity ≥120° / s) realizes automatic tape retraction, and the tensioning time of the whole layer closed loop is reduced by 70%. Attached Figure Description

The inner turntable 4 is installed on the threaded end of the inner insert rod 2. The inner turntable 4 can be rotated to adjust its position on the threaded end of the inner insert rod 2. The support sleeve 5 is sandwiched between the outer turntable 3 and the inner turntable 4. The inner cavity of the support sleeve 5 is provided with a signal transmitting unit 6. The support sleeve 5 can fix the distance between the outer turntable 3 and the inner turntable 4. The inner cylinder of the non-threaded end of the outer rod 1 can be inserted into the insertion rod body 1001 of the stop platform 10. The position of the stop platform 10 at the outer end of the outer rod 1 can be fixed by inserting the warning tape insert 9 into the through hole 10011 reserved between the non-threaded end of the outer rod 1 and the insertion rod body 1001 of the stop platform 10.

[0121] like Figure 3 As shown, the outer sleeve rod 1 is a standardized steel pipe component with an outer diameter of 48mm and a wall thickness of 3mm. It has an overall hollow tubular structure, and its total length is set within a tolerance range of 1250mm ± 10mm. The outer sleeve rod 1 has a first threaded connection part 101 machined at one end along the axial direction. The first threaded connection part 101 extends axially by 100mm ± 2mm and is machined using a standard M48×3 thread specification. Starting from the end of the first threaded connection part 101 and extending 50mm towards the rod body, the threads are arranged at equal intervals of 100mm ± 1mm ​​along the axial direction of the outer sleeve rod 1. There are five positioning through holes 102; each positioning through hole 102 is formed by a through hole orthogonal to the axis of the rod body; the diameter of each positioning through hole 102 is 12mm ± 0.25mm, and the center line of each positioning through hole 102 is perpendicular to the axis of the outer sleeve rod 1 and is symmetrically distributed at 180°; the inner wall of each positioning through hole 102 is deburred and galvanized for rust prevention; a fixing through hole 103 with a diameter of 12mm is provided at a distance of 60mm ± 2mm from the end of the rod body away from the first threaded connection part 101; the axis of the fixing through hole 103 is in the same direction as the aforementioned positioning through holes 102.

[0122] like Figure 4As shown, the inner insert rod 2 is a precision steel tube component with an outer diameter adapted to the inner diameter of the outer sleeve rod 1. Its outer diameter tolerance is controlled within the range of 42mm-0.2mm to 42mm-0.5mm, its wall thickness is 3mm, and its total length is 1450mm±15mm. One axial end of the inner insert rod 2 is provided with a machined second threaded connection part 201, 200mm±3mm in length. The second threaded connection part 201 uses an M42×3 thread specification. The root of the second threaded connection part 201 is subjected to roll forming reinforcement treatment to improve shear strength. Starting at a position 100mm ± 2mm from the non-threaded connection, an array of 17 sets of adjusting through holes 202 are continuously arranged at equal intervals of 50mm ± 1mm ​​along the axial direction of the inner rod 2. Each set of adjusting through holes 202 consists of a through hole orthogonal to the axis of the rod body, with a diameter of 12mm ± 0.25mm. The center line of the adjusting through holes 202 is perpendicular to the axis of the rod body and is symmetrically distributed at 180°. Each adjusting through hole 202 and the positioning through hole 102 of the outer rod 1 form a multi-level adjustable mating structure, realizing a continuous adjustment capability of axial extension stroke up to 800mm.

[0123] like Figure 5 , Figure 6 As shown, the outer turntable 3 is a steel component made of the same material as the outer sleeve rod 1 and the inner insert rod 2. Its structure includes an integrally formed first disc body 301, a first central shaft cylinder 302, and a first rotating part 303. The first disc body 301 is a circular steel disc with an outer diameter of 350mm ± 5mm and a thickness of 15mm ± 0.5mm, and has a central through hole 3011 with a diameter of 48mm in the center. The front of the first disc body 301 is stamped with an array of several first friction pins 3012. The first friction pins 3012 are made of... The asymmetrical streamlined design features a 15° acute-angled long guide wedge surface (1.5mm / 4mm radius of curvature, 8mm length) for the rotational tightening direction and a 6mm rounded limiting arc surface for the relaxation direction; the three-dimensional ridge height decreases from 6mm to 2mm; the asymmetrical structure of the first friction pin 3012 can achieve a tightening torque of no more than 120N·m and a relaxation torque difference of no more than 40N·m; the first friction pin 3012 is distributed radially in a fan shape at 15° equal angular intervals, covering a 300mm diameter area on the outer edge of the disc to form an anti-slip interface.

[0124] The first central shaft cylinder 302 is vertically welded to the center of the back of the first disc body 301. Its outer diameter is 55mm ± 0.5mm, inner diameter is 48mm ± 0.2mm, and axial length is 60mm ± 2mm. The inner wall of the first central shaft cylinder 302 is machined with an M48×3 internal thread section 3021 that matches the first threaded connection part 101 of the outer sleeve rod 1. The joint between the first central shaft cylinder 302 and the first disc body 301 is connected by a double-sided circumferential weld. The first rotating part 303 includes three sets of force transmission components symmetrically distributed at 120°. Each set of force transmission components consists of a square-section connecting rod 3031 and a first torque cylinder 3032. The square-section connecting rod 3031 is 15mm × 15mm. The solid steel bar is 50mm±1mm in length. One end of it is welded to the outer wall of the first central shaft cylinder 302, with the welding angle using an R5mm rounded transition. The other end of it is connected to the side wall of the first torsion cylinder 3032 with a K-type bevel weld. The first torsion cylinder 3032 is a steel pipe section with an outer diameter of 55mm±0.5mm, a wall thickness of 3.5mm±0.2mm, a length of 200mm±3mm, and an inner diameter of 48mm, which forms a clearance fit with the standard scaffolding steel pipe. The plane containing the axes of the three sets of first torsion cylinders 3032 maintains a parallelism tolerance of ≤0.1mm with the plane of the first disc 301.

[0125] like Figure 7 , Figure 8 As shown, the inner turntable 4 inherits the overall structure of the outer turntable 3. The diameter of the second central shaft through hole 4011 in the center of the second disc body 401 is reduced to 42mm ± 0.2mm. The inner diameter of the second central shaft cylinder 402 is precisely machined to 42mm and an M42×3 internal thread section 4021 is provided to adapt to the second threaded connection part 201 of the inner insertion rod 2, which is 200mm long and has a diameter of M42×3. The joint between the second central shaft cylinder 402 and the second disc body 401 is connected by a double-sided circumferential weld. The installation position is consistent with the second central shaft cylinder 402 of the outer turntable 3. The array distribution and specifications of the second friction pins 4012 on the front of the second disc body 401 are consistent with the first disc body 301 of the outer turntable 3. The installation position and specifications of the second rotating part 403 are consistent with the first rotating part 303 of the outer turntable 3. The inner turntable 4 can be locked with the second threaded connection part 201 of the inner insertion rod 2, while ensuring complete interchangeability of the force transmission components with the outer turntable 3.

[0126] like Figure 9 , Figure 10 , Figure 11As shown, the main body of the support sleeve 5 is a modular steel composite structure, consisting of a support plate 501, a sleeve body 502, and a handle 503.

It forms a coplanar splice with the inner ring and straight section area of ​​the support plate 501. The sleeve 502 has two length specifications: 160mm±2mm (suitable for 200mm±5mm thick structures) and 210mm±2mm (suitable for 250mm±5mm thick structures). The handle 503 is forged from steel and is cylindrical with a diameter of 16mm±0.2mm. It is located between the tops of the two support plates 501. The two ends of the handle 503 are connected to the support plate 501 with full penetration fillet welds.

The button cap 602 is made of nylon and has a diameter of 9mm ± 0.1mm. The button cap 602 protrudes 5mm through the limiting hole 5016. The annular boss 6021 on the outer edge of the button cap 602 forms an axial limit with the limiting hole 5016. The metal pin 6022 (diameter of 2mm ± 0.05mm) at the rear of the button cap 602 is connected to the cavity limiting baffle 6031 (opening φ2.1mm) through a cylindrical helical spring 603 (wire diameter of 0.4mm, free length of 12mm ± 0.2mm), so as to achieve a pressing stroke of 2.0mm ± 0.2mm and an operating life of ≥500,000 times.

[0136] like Figure 24 , 25 As shown, the stopping platform 10 adopts a high-strength steel structure, consisting of a plug-in rod body 1001 and a stopping disc 1002; the plug-in rod body 1001 is a steel pipe with an outer diameter of 42mm, a wall thickness of 3mm±0.15mm, and a length of 370mm±2mm; a through insertion hole 10011 with a diameter of φ12mm±0.2mm is opened on the plug-in rod body 1001 at a distance of 85mm±0.5mm from the end face; the stopping disc 1002 is a circular steel plate with a diameter of 600mm±5mm (thickness of 5mm±0.3mm). The stop disk 1002 is connected to the side wall of the plug-in rod body 1001 via a full penetration circumferential weld; the lower surface of the stop disk 1002 is welded with 8 radial reinforcing ribs 10021 (rib height 20mm±1mm, rib width 8mm±0.5mm), with an included angle of 20°±1° between the ribs, extending to the edge of the disk; the upper surface of the stop disk 1002 is laser-cut with an H-shaped groove 10022 (line width 80mm±2mm, groove depth 3mm±0.2mm); the stop disk 1002 can carry drones ≤25kg (such as DJI Matrice 300); the horizontal accuracy of the stop disk 1002 ensures take-off and landing stability (tilt tolerance ≤3°).

[0137] For detailed usage instructions, please see below:

[0138] The main structure of the building can be provided with several types of tie points for wall ties according to the floor plan. The first type is the structural floor slab; the second type is the anti-reflective curb set on the floor slab; and the third type is the door and window openings. The installation method of the present invention will be described later for the above three types of tie points.

[0139] like Figure 26 As shown:

[0140] Step 1: When engineers receive the building floor plans, they should keep in mind the national standards for the installation of wall ties in buildings, which require a three-step, three-span configuration. That is, starting from the second floor, a different number of wall ties need to be installed on the building side for every other floor, and the horizontal spacing between the wall ties should not exceed 4.5m. Based on the building's facade features and floor plan, the engineer drew up a plan for the erection of scaffolding wall ties, noting that the points requiring wall ties were numbered in a specific order, such as: "1-A, 1-B...1-R" clockwise on the 2nd floor; "2-A, 2-B...2-R" clockwise on the 4th floor; "1-A, 1-B...1-R" clockwise on the 6th floor; and "2-A, 2-B...2-R" clockwise on the 8th floor. Wall ties numbered 1-A on multiple floors used components with the same coded signal transmission unit 6; wall ties numbered 1-B on multiple floors also used components with the same coded signal transmission unit 6, and so on. For building sections where ordinary wall ties were conveniently installed, ordinary wall ties were used. The scaffolding workers then erected the external scaffolding according to the engineer's drawings.

[0141] like Figure 27 As shown:

[0142] Step Two: When the external scaffolding is erected to the second floor and the wall ties are ready for installation, the worker first rotates the first disc 301 of the outer turntable 3 so that it faces the building and is installed with the first threaded connection 101 of the outer sleeve rod 1. Then, the inner insert rod 2 is inserted into the outer sleeve rod 1 from the side near the first threaded connection 101, with the second threaded connection 201 of the inner insert rod 2 on the same side as the first threaded connection 101 of the outer sleeve rod 1. Next, according to the thickness of the building wall or balcony curb (200mm / (250mm), adjust the positions of the outer sleeve rod 1 and the inner insert rod 2. If the structural thickness is 200mm, control the distance between the end of the first threaded connection part 101 of the outer sleeve rod 1 and the smooth pipe section clamped by the second threaded connection part 201 of the inner insert rod 2 to about 200mm, and align the positioning through hole 102 with the adjustment through hole 202; finally, use two hooks 8 to insert into the two nearest and adjacent positioning through holes 102 of the first threaded connection part 101 of the outer sleeve rod 1 to lock the positions of the outer sleeve rod 1 and the inner insert rod 2.

[0143] like Figure 28 As shown:

[0144] Step 3: After adjusting the assembly of the outer sleeve rod 1 and the inner insert rod 2, use two right-angle fasteners 11 to adjust and fix the assembly to the positioned outer frame upright 12. The height of the assembly of the outer sleeve rod 1 and the inner insert rod 2 is approximately 100mm higher than the anti-sill portion 13. In planar position, the smooth pipe section clamped by the outer sleeve rod 1 and the inner insert rod 2 is precisely positioned directly above the anti-sill portion 13.

[0145] like Figure 29 As shown:

[0146] Step 4: First, the worker holds the first rotating part 303 of the outer turntable 3 and rotates it to adjust the position of the first disc body 301 so that the first friction pin 3012 of the first disc body 301 contacts the side of the anti-slip part 13. Then, the worker holds the second rotating part 403 of the inner turntable 4 and screws the inner turntable 4 onto the inner insert rod 2 via the second threaded connection part 201. Next, the support sleeve 5 (200mm wide) of the signal transmitting unit 6 with the designated number is placed into the smooth tube section sandwiched between the outer turntable 3 and the inner turntable 4. The support plate 501 of the signal transmitting unit 6 is installed facing the outer turntable 3, and a numbered indicator sticker is affixed to the support sleeve 5.

[0147] like Figure 30 , Figure 31 As shown:

[0148] Step 5: The worker holds the second rotating part 403 of the inner turntable 4 and rotates it clockwise. The inner turntable 4 screws into the other side of the reverse retainer 13 along the second threaded connection part 201 of the inner insert rod 2. When the worker feels that rotating the second rotating part 403 is difficult, a steel pipe 14 about 1m long can be inserted into a second torque cylinder 4032 and turned clockwise to lock the inner and outer sides of the reverse retainer 13 between the inner turntable 4 and the outer turntable 3. At the same time, when the inner turntable 4 and the outer turntable 3 compress the support sleeve 5, the button cap 602 is gradually squeezed, and the metal pin 6022 at its rear gradually squeezes the gap between the positive electrode guide plate 604 and the positive electrode of the battery 601. As the inner turntable 4 and outer turntable 3 lock the inner and outer sides of the anti-recessed portion 13, the metal pin 6022 at the rear of the button cap 602 presses the positive electrode guide plate 604 to make contact with the positive electrode of the battery 601, thus energizing the device. The signal indicator 608 then lights up, indicating that the inner turntable 4 and outer turntable 3 have locked the structure, and the wall connector is securely connected to the structure. Simultaneously, the external exposed wire 6071 is energized and emits radio electromagnetic waves, disseminating a 2.4GHz wireless signal with a digital code carrying the wall connector chip number.

[0149] like Figure 32 , 33 As shown:

[0150] Step Six: In building locations where it is convenient to install ordinary wall ties, such as the edge of a floor slab, the method of pre-embedding steel pipe fittings 17 at the edge of the floor slab can still be used. The pre-embedded steel pipe fittings 17 are vertical, and the height above the floor slab surface is generally 250mm-300mm. Then, the straight sleeve 16 is rotated and fitted onto the second threaded connection part 201 of the inner insertion rod 2. The straight sleeve 16 is a threaded ordinary steel pipe with a pipe section length of 250mm-300mm; the inside of the straight sleeve 16 is threaded, and the thread size matches the thread of the second threaded connection part 201 of the inner insertion rod 2. Finally, the worker uses three right-angle fasteners 11 to connect and lock the outer outer rod 1, the two outer scaffold uprights 12, and the straight sleeve 16 to complete the connection.

[0151] like Figure 34 As shown:

[0152] Step Seven: At the window opening 18, where it is relatively difficult to install ordinary wall ties. First, after adjusting the assembly of the outer sleeve rod 1 and the inner insert rod 2, use two right-angle fasteners 11 to adjust and fix the assembly to the positioned outer frame upright 12. The assembly of the outer sleeve rod 1 and the inner insert rod 2 is approximately 150mm higher than the windowsill of the window opening 18. In planar position, the smooth tube section clamped by the outer sleeve rod 1 and the inner insert rod 2 is precisely positioned above the windowsill of the window opening 18. Then, the worker holds the first rotating part 303 of the outer turntable 3 and rotates it, adjusting the position of the first disc body 301 so that the first friction pin 3012 of the first disc body 301 contacts the outer edge of the window opening 18. Next, the worker holds the second rotating part 403 of the inner turntable 4 and screws the inner turntable 4 onto the inner insert rod 2 through the second threaded connection part 201. Furthermore, the support sleeve 5 (200mm wide) with the designated numbered signal transmitting unit 6 is placed into the smooth tube section sandwiched between the outer turntable 3 and the inner turntable 4. The support plate 501 with the signal transmitting unit 6 installed faces the outer turntable 3, and a numbered sticker is affixed to the support sleeve 5. Finally, the worker applies force to lock the inner and outer sides of the window opening 18 with the discs of the inner turntable 4 and the outer turntable 3. The metal pin 6022 at the rear of the button cap 602 presses the positive electrode guide plate 604 to make contact with the positive electrode of the battery 601, thus energizing the circuit. The signal indicator 608 then lights up, indicating that the discs of the inner turntable 4 and the outer turntable 3 have locked the window opening 18, and the wall connector is securely connected to the structure. At the same time, the external open-circuit line 6071 transmits radio electromagnetic waves, spreading the 2.4GHz wireless signal with the digital code of the wall-connecting chip number (effective coverage radius of 100m, the signal strength will decrease when passing through a single concrete floor, and the signal strength will basically disappear when passing through two concrete floors).

[0153] like Figure 35 ,36 As shown in Figure 37:

[0154] Step 8: After the wall ties are locked to the main structure of the building, the signal transmitting unit 6 is powered on, the signal indicator 608 lights up, and the external exposed wire 6071 emits radio electromagnetic waves. Taking a 6-story building as an example, the wall ties are installed on even-numbered floors of the 2nd, 4th, and 6th floors, and the safety officer also patrols the even-numbered floors of the 2nd, 4th, and 6th floors. The site safety officer holds the signal receiver 7 and powers it on, and the power LED 706 of the signal receiver 7 lights up. The signal receiver 7 has a built-in signal conversion chip 705, which identifies multiple 2.4GHz wireless signals with digital codes, and a certain LED bead 7081 on the LED array pad 708 corresponding to each code lights up. For example: When inspecting the wall ties on the second floor, the safety officer focuses on the lighting status of the red LEDs 7081 (1-A to 1-R) on the left side of panel 702. They locate any unlit red LEDs 7081 and, using the 1-A to 1-R symbols on panel 702, locate the faulty wall tie number and location on the scaffolding erection plan. Similarly, when inspecting the wall ties on the fourth floor, the safety officer focuses on the lighting status of the red LEDs 7081 (2-A to 2-R) on the right side of panel 702. They locate any unlit red LEDs 7081 and, using the 2-A to 2-R symbols on panel 702, locate the faulty wall tie number and location on the scaffolding erection plan. Similarly, the administrator patrols the sixth floor, focusing on LEDs 7081 marked with symbols 1-A to 1-R on the left side of panel 702; the safety officer patrols the eighth floor, focusing on LEDs marked with symbols 2-A to 2-R on the right side of panel 702, and so on. For any malfunctioning wall tie, after locating its position, direct inspection and secondary reinforcement of the wall tie are carried out. The safety officer patrols the floors along the main axis of the building to prevent signal blind spots caused by differences in wall layout at certain inspection points, thus ensuring signal reception.

[0155] like Figure 38 , 39 As shown in Figure 40:

[0156] Step Nine: After completing the installation and fastening of the scaffolding, workers need to install a safety net 20 every three floors in the gap between the external scaffolding and the main building. The purpose of the safety net 20 is to catch building materials and construction waste falling from the floor edges to prevent injury to workers working on the external scaffolding, and also to improve the psychological safety of workers working near the building edges. Traditional safety nets 20 have very limited tensile strength and impact resistance, and often break because they cannot catch large building materials falling. This invention is equipped with hooks 8, which are inserted precisely within the positioning through holes 102 in the gap between the outer outer rod 1 and the inner inner rod 2 between the external scaffolding and the main building. The two hooks 802 of the hook 8 can hook into the holes on the perforated strip 19. The perforated strip 19 is a strip with a certain toughness and strength, and its holes can be fixed to the two hooks 802 of the hook 8, realizing the connection of multiple wall ties in pairs. The principle for selecting and placing the holes of the perforated tape 19 on the two hooks 802 of the hook 8 is to ensure that the perforated tape 19 is always in a relatively taut state. On the construction site, wire can also be used instead of the perforated tape 19, wrapped around the two hooks 802 of the hook 8 to achieve the same effect. Finally, the workers install the safety net 20, with the open middle section of the safety net 20 placed directly above the perforated tape 19. When building materials and construction waste fall from the edge of the building, the safety net 20, reinforced by the taut perforated tape 19, greatly enhances its ability to intercept falling debris and is less prone to damage.

[0157] like Figure 41 , 42 As shown in Figure 43:

[0158] Step 10: After the external scaffolding is erected, a facade safety net 21 needs to be installed on the outside of the scaffolding to completely enclose it. Generally, a warning line needs to be set every three floors of the external scaffolding to distinguish the height of the scaffolding and to serve as a warning. The operation is as follows: Workers insert warning tape inserts 9 into the fixing through holes 103 of the outer rod 1 of each wall tie. Next, the worker forcefully pulls out the lever 904 on each side of the shaft cylinder 903, and the warning tape 9035 fixed to the rear of the lever 904 is pulled out accordingly. Then, the worker holds the lever 904 and moves it towards the next warning tape insert 9, inserting the lever 904 from top to bottom into the arc-shaped notch 90311 in the shaft cylinder shell 9031 of the previous warning tape insert 9, thus horizontally fixing the lever 904. Under the interaction of the horizontal fixing force of the lever 904 within the arc-shaped notch 90311 and the rotational force of the central rotating shaft 9032 inside the shaft cylinder 903, the warning tape 9035 remains vertically taut and open. In this way, the lever 904 of each warning tape insert 9 is fixed into the arc-shaped notch 90311 in the shaft cylinder shell 9031 of the previous warning tape insert 9. To achieve a tensioned state, the warning tape 9035 at the corner of the external scaffolding can be bent at a 90° angle using the external scaffolding upright 12 at the corner as a corner support. Therefore, the warning tape 9035 can achieve a closed loop state with the entire floor connected end to end.

[0159] like Figure 44 , 45 As shown in Figure 46, drones 22 are increasingly widely used in engineering projects. When supplementary surveillance cameras are needed in blind spots of project management monitoring, drones 22 can serve as low-cost supplementary camera equipment for project shooting and monitoring. The battery life of drones 22 is generally around half an hour. The quadcopter propellers 2201 and cameras 2202 of drones 22 are the main power-consuming devices, especially the quadcopter propellers 2201, which account for 80% of the drone's power consumption when in operation. However, when the quadcopter propellers 2201 are off and only the drone's camera 2202 is running for image shooting and transmission, the drone's battery can achieve a battery life of about 5 hours, enabling long-term monitoring. The specific installation method is that the outer rod 1 of the external scaffolding wall tie and the landing platform 10 are connected by inserting the warning tape insert 9. The landing platform 10 is generally installed at a high position on the external scaffolding and in the blind spots of the project's monitoring. When monitoring and filming of the area are required, the drone 22 flies above the landing platform 10, adjusts the position of the camera 2202, and then slowly descends to the H-shaped groove 10022 on the landing platform 10. Finally, the quadcopter propellers 2201 are turned off, and only the camera 2202 is operated to perform filming or monitoring.

[0160] like Figure 47 ,48 As shown, the multifunctional wall tie of the building scaffolding of this invention is relatively convenient to install, dismantle, and re-establish. When the on-site construction reaches the stage of installing the railing 23, the wall tie of the balcony curb 13 needs to be temporarily removed. The worker only needs to rotate the inner turntable 4 and unscrew it from the second threaded connection 201 of the inner insert rod 2, and then remove the support sleeve 5; then install the railing 23 on the curb 13; finally, insert the support sleeve 5 axially from the inner insert rod 2 into the gap between the lower horizontal bar of the railing 23 and the balcony curb 13, and hang it on the inner insert rod 2. Then rotate the inner turntable 4 and screw it in from the second threaded connection 201 of the inner insert rod 2 to firmly lock the balcony curb 13 from both sides, and then screw the inner turntable 4 in until the signal indicator 608 of the signal transmitting unit 6 of the support sleeve 5 lights up. When the window frame 24 needs to be installed in the window opening 18, the wall ties of the window opening 18 need to be temporarily removed. The worker only needs to rotate the inner turntable 4 and unscrew it from the second threaded connection 201 of the inner insert rod 2, and then remove the support sleeve 5; then install and fix the window frame 24 on the window opening 18; finally, hang the support sleeve 5 from top to bottom on the inner insert rod 2. Next, rotate the inner turntable 4 and screw it in from the second threaded connection 201 of the inner insert rod 2 to firmly lock the window opening 18 from both sides, and then screw the inner turntable 4 in until the signal indicator 608 of the signal transmitting unit 6 of the support sleeve 5 lights up.

[0161] like Figure 49 As shown, the site safety officer checks the wall ties for secure installation mainly in two phases. Phase 1: After the external scaffolding is erected, the wall ties are initially installed. The site safety officer, holding a signal receiver 7, patrols the floors where the wall ties are installed, observing the illumination of the LEDs 7081 on the receiver 7 to identify wall ties requiring secondary inspection and reinforcement. After this work is completed, the safety officer can remove the battery 601 from the signal transmitter unit 6. Phase 2: During the installation of window frames 24 and railings 23, the safety officer reinstalls the batteries 601 into each signal transmitter unit 6. After the workers have safely installed the window frames 24 and railings 23 and reinstalled the wall ties, the safety officer finally checks the wall ties again using the signal receiver 7.

[0162] like Figure 50 As shown, when the project requires the dismantling of the external scaffolding, all parts of the wall tie of this invention can be recycled. After being returned to the factory for cleaning and simple maintenance, they can be reused in the wall ties of the next external scaffolding project, realizing recycling and amortization of construction costs.

The construction method of the multifunctional wall tie for building scaffolding according to claim 9, characterized in that, The steps are as follows: S1: Draw a plan of scaffolding wall tie erection based on the building's facade features and floor plan, and indicate the locations where wall ties need to be installed, numbering them in a certain order. S2: When the external scaffolding is erected to the second floor and the wall ties are ready for installation, the worker first rotates the first disc (301) of the outer turntable (3) so that the outer turntable (3) is facing the building and the first threaded connection (101) of the outer rod (1) is installed; then, the inner insert rod (2) is inserted into the outer rod (1) from the side near the first threaded connection (101) of the outer rod (1), and the second threaded connection (201) of the inner insert rod (2) is on the same side as the first threaded connection (101) of the outer rod (1); then, according to the thickness of the building wall or balcony curb, Adjust the positions of the outer rod (1) and the inner rod (2). If the structural thickness is 200mm, the distance between the end of the first threaded connection part (101) of the outer rod (1) and the smooth pipe section clamped by the second threaded connection part (201) of the inner rod (2) is controlled at 200mm. Align the positioning through hole (102) with the adjustment through hole (202). Finally, use two hooks (8) to insert into the two nearest and adjacent positioning through holes (102) of the first threaded connection part (101) of the outer rod (1) to lock the positions of the outer rod (1) and the inner rod (2). S3: After adjusting the assembly of the outer rod (1) and the inner rod (2), use two right-angle fasteners (11) to fix the assembly on the positioned outer frame upright (12); the height of the assembly of the outer rod (1) and the inner rod (2) is higher than the height of the reverse slope (13), and in the plane position, the smooth pipe section clamped by the outer rod (1) and the inner rod (2) is exactly adjusted to be directly above the reverse slope (13); S4: First, the worker holds the first rotating part (303) of the outer turntable (3) and rotates it to adjust the position of the first disc body (301) so that the first friction nail (3012) of the first disc body (301) contacts the side of the anti-slip part (13); then, the worker holds the second rotating part (403) of the inner turntable (4) and screws the inner turntable (4) into the inner insert rod (2) through the second threaded connection part (201); next, the support sleeve (5) of the signal transmitting unit (6) with the specified number is placed into the smooth pipe section between the outer turntable (3) and the inner turntable (4), the support plate (501) of the signal transmitting unit (6) is installed facing the outer turntable (3), and the numbered indicator sticker is affixed to the support sleeve (5); S5: The worker holds the second rotating part (403) of the inner turntable (4) and rotates it clockwise. The inner turntable (4) is screwed into the other side of the anti-slip part (13) along the second threaded connection part (201) of the inner insert rod (2). When the worker feels that it is difficult to rotate the second rotating part (403), a steel pipe (14) is inserted into a second torque cylinder (4032) and turned clockwise to lock the inner and outer sides of the anti-slip part (13) by the disc bodies of the inner turntable (4) and the outer turntable (3). At the same time, when the disc bodies of the inner turntable (4) and the outer turntable (3) compress the support sleeve (5), the button end cap (602) is gradually squeezed, and the metal pin (6) at its rear is squeezed. 022) Gradually squeeze the gap between the positive electrode guide plate (604) and the positive electrode of the battery (601); as the inner turntable (4) and the outer turntable (3) lock the inner and outer sides of the anti-sunken part (13), the metal pin (6022) at the rear of the button cap (602) squeezes the positive electrode guide plate (604) and the positive electrode of the battery (601) to make contact and energize, and the signal indicator (608) lights up, indicating that the inner turntable (4) and the outer turntable (3) have locked the structure and the wall connector is firmly connected to the structure; at the same time, the external open wire (6071) is energized and emits radio electromagnetic waves, dispersing the 2.4GHz wireless signal with the digital code of the wall connector chip number; S6: In building sections where it is convenient to install ordinary wall ties, steel pipe fittings (17) are pre-embedded at the edge of the floor slab. The pre-embedded steel pipe fittings (17) are vertical. Then, a straight sleeve (16) is rotated into the second threaded connection part (201) of the inner insert rod (2). The inside of the straight sleeve (16) is threaded, and the thread size matches the thread of the second threaded connection part (201) of the inner insert rod (2). Finally, the worker uses three right-angle fasteners (11) to connect and lock the outer sleeve rod (1), the two outer frame uprights (12) and the straight sleeve (16). S7: In the window opening (18) where it is difficult to install ordinary wall ties, first, after adjusting the combination of the outer rod (1) and the inner rod (2), use two right-angle fasteners (11) to adjust and fix the combination to the positioned outer frame upright (12); the combination of the outer rod (1) and the inner rod (2) is higher than the windowsill of the window opening (18) in height; in planar position, the smooth pipe section clamped by the outer rod (1) and the inner rod (2) is precisely adjusted in the window opening. (18) directly above the windowsill; then, the worker holds the first rotating part (303) of the outer turntable (3) and rotates it to adjust the position of the first disc body (301) so that the first friction nail (3012) of the first disc body (301) contacts the outer edge of the window opening (18); next, the worker holds the second rotating part (403) of the inner turntable (4) and screws the inner turntable (4) into the inner insert rod (2) through the second threaded connection part (201); furthermore, Place the support sleeve (5) of the signal transmitting unit (6) with the specified number into the smooth pipe section sandwiched between the outer turntable (3) and the inner turntable (4). The support plate (501) of the signal transmitting unit (6) is facing the outer turntable (3), and a numbered sticker is affixed to the support sleeve (5). Finally, the worker uses force to lock the inner and outer sides of the window opening (18) with the discs of the inner turntable (4) and the outer turntable (3). The button cap ( 602) The metal pin (6022) at the rear presses the positive electrode guide plate (604) to make contact with the positive electrode of the battery (601) to conduct electricity. The signal indicator (608) then lights up, indicating that the inner turntable (4) and the outer turntable (3) have locked the window opening (18) and the wall connector is firmly connected to the structure. At the same time, the external open wire (6071) emits radio electromagnetic waves to spread the 2.4GHz wireless signal with the digital code of the wall connector chip number. S8: After the wall tie and the main body of the house are locked, the signal transmitting unit (6) is powered on, the signal indicator (608) lights up, and the external exposed wire (6071) emits radio electromagnetic waves. The site safety officer holds the signal receiver (7) and powers it on. The power LED (706) of the signal receiver (7) lights up. The signal conversion chip (705) built into the signal receiver (7) identifies the multiple 2.4GHz wireless signals with digital codes. A certain lamp bead (7081) on the LED array pad (708) corresponding to each code lights up. For a certain failed wall tie, after locking the position, the wall tie is directly inspected and reinforced for the second time. S9: After the installation and fastening of the scaffolding is completed, the workers need to set up a safety net (20) every 3 floors in the gap between the outer scaffolding and the main building. The insertion position of the hook (8) is exactly within the range of the positioning through hole (102) between the outer rod (1) and the inner rod (2) in the gap between the outer scaffolding and the main building. The two hooks (802) of the hook (8) hook the holes on the perforated strip (19) and connect the multiple wall ties in pairs. Finally, the workers install the safety net (20), and the middle open part of the safety net (20) is placed directly above the perforated strip (19). When building materials and construction waste fall from the side of the floor, the safety net (20) intercepts the falling debris with the support and obstruction of the taut perforated belt (19); S10: After the scaffolding is erected, a facade safety net (21) is erected on the outside of the scaffolding to completely enclose the scaffolding; workers insert warning tape inserts (9) into the fixing through holes (103) of the outer sleeve rods (1) of each wall tie; then, workers pull out the tie rods (904) on the side of each shaft cylinder (903), and the warning tape (9035) fixed at the back of the tie rod (904) is pulled out; then, workers hold the tie rod (904) and approach the upper warning tape insert (9), and insert the tie rod (904) from top to bottom into the arc-shaped notch (90311) in the outer shell (9031) of the shaft cylinder of the upper warning tape insert (9) to achieve horizontal fixation of the tie rod (904); the warning tape (9035) behind the tie rod (904) is then inserted into the outer shell (9031) of the upper warning tape insert (9) to achieve horizontal fixation of the tie rod (904); The warning tape (9035) maintains a vertically taut and open state under the action of the horizontal fixing force of the tie rod (904) and the rotational force of the central rotating shaft (9032) inside the shaft cylinder (903) within the arc-shaped notch (90311); the tie rod (904) of each warning tape insert (9) is fixed to the arc-shaped notch (90311) in the outer shell (9031) of the shaft cylinder of the previous warning tape insert (9); if the warning tape (9035) at the corner of the external scaffolding is to be in a tensioned state, it is achieved by bending it 90° with the external scaffolding upright (12) at the corner of the external scaffolding as a corner support; the warning tape (9035) achieves a closed loop state with the entire layer connected end to end.
