Description

Technical Field

[0001] The present invention relates to the technical field of building engineering construction, and in particular to a multifunctional wall connecting member for building external scaffolding and a construction method thereof, which is suitable for the most common fastener steel pipe external scaffolding at a building construction site. Background Art

[0002] During the main building's structural construction, external scaffolding must be erected at the same height as the building's floor level to facilitate worker access and ensure safety throughout the building's facade. The external scaffolding is typically secured to the building structure using pre-embedded vertical short steel pipes (48mm diameter, 3mm wall thickness) during the concrete slab pouring process. After the concrete sets, a horizontal standard steel pipe is used to secure the external scaffolding members to the pre-embedded vertical short steel pipes via fasteners, securing the scaffolding to the building and achieving stability. National regulations require that the entire external scaffolding be secured to the main structure at every other floor along the vertical axis, and horizontally at intervals of 4.5 meters. Therefore, numerous wall ties are required throughout the entire building's facade.

[0003] The construction and installation of the traditional wall connecting parts have the following significant defects:

[0004] 1. Functional singularity defect

[0005] Traditional wall ties only have a one-way tensioning function and cannot simultaneously meet the complex functional requirements of scaffolding vertical load transfer, new drone parking, safety warning sign installation, and enhanced safety measures, resulting in the need to add a variety of auxiliary components on site.

[0006] 2. Embedded parts are not recyclable

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

[0008] 3. Process conflicts and inconvenience in recovery lead to illegal operations

[0009] When temporary wall ties are removed during building component installation (such as window frames or railings), traditional pre-buried ties require scaffolders to loosen the fasteners with a dedicated torque wrench. Once the installation is complete, the ties must be tightened again with the torque wrench. To meet deadlines or because they lack tools, workers installing window frames or railings often choose to remove them without restoring them or simply leave steel pipes hanging for inspection. This leaves the scaffolding untied and can lead to safety accidents.

[0010] 4. Hidden defects are difficult to detect

[0011] After traditional wall ties are removed, there's no visual identification or electronic record of their missing status, requiring safety officers to manually inspect each floor. Statistics show that approximately 40% of missing wall ties go undetected due to their concealed nature, creating a "management blind spot."

[0012] It is inconvenient to install wall connecting parts at window openings and balcony recesses and there are many quality risks.

[0013] The traditional clamping method for wall ties at window openings requires fasteners to clamp the window frame. Applying pressure exceeding 10kN can easily deform the plastic-steel window frame. The pre-buried short steel pipes and window frame anchor bolts also clash 30% of the time, requiring chiseling and rework. The pre-buried short steel pipes at the balcony's undercut are anchored to a depth of only 60-80mm (regulations require ≥120mm), resulting in insufficient pullout resistance, reaching only 55% of the design value. Removing the pre-buried parts to seal the holes can easily cause microcracks, increasing the probability of rainwater infiltration fourfold compared to intact structures.

[0014] In response to the above problems, the present invention urgently needs to develop a wall connection component that has multiple functionalities, can be reused multiple times, is easy to dismantle and restore, can promptly detect the working status of the wall connection component through a signal terminal, and can adapt to multiple scenarios.

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

[0027] S1: Draw the plan of scaffolding wall connection parts according to the building's facade characteristics and plane position, and indicate the points where wall connection parts need to be set up and number them in a certain order;

[0028] S2: When the external scaffolding is erected to the second floor and the wall connecting parts are ready for erection, the workers first rotate the first disk of the outer turntable toward the building so that the outer turntable is installed with the first threaded connection part of the outer rod; then, the inner rod is inserted into the outer rod from the side close to the first threaded connection part of the outer rod, and the second threaded connection part of the inner rod is on the same side as the first threaded connection part of the outer rod; then, according to the thickness of the building wall or balcony anti-step, the positions of the outer rod and the inner rod are adjusted. If the structural thickness is 200mm, the distance between the end of the first threaded connection part of the outer rod and the smooth pipe section clamped by the second threaded connection part of the inner 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 positioning through holes closest to and adjacent to the first threaded connection part of the outer rod to achieve position locking of the outer rod and the inner rod;

[0029] S3: After the outer rod and inner rod assembly are adjusted, the assembly is adjusted and fixed to the positioned outer frame upright using two right-angle fasteners; the outer rod and inner rod assembly is higher than the height of the anti-ridge portion, and in a planar position, the smooth pipe section clamped by the outer rod and inner rod is adjusted exactly above the anti-ridge portion;

[0030] S4: First, the worker holds the first rotating part of the outer turntable and rotates it, adjusting the position of the first disk body so that the first friction pin of the first disk body contacts the side of the anti-ridge part; then, the worker holds the second rotating part of the inner turntable and screws the inner turntable onto the inner insert rod through the second threaded connection part of the inner insert rod; then, the support sleeve with the signal transmitting unit installed with the designated number is placed on the smooth pipe section sandwiched between the outer turntable and the inner turntable, the support plate of the signal transmitting unit is installed toward the outer turntable side, and a 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, and the inner turntable is screwed into the other side of the anti-ridge part along the second threaded connection part of the inner rod; when the worker feels that it is difficult to rotate the second rotating part, he uses a steel pipe to insert a second torque cylinder and twist it clockwise, so that the inner and outer turntables lock the inner and outer sides of the anti-ridge part; at the same time, when the inner and outer turntables compress the support sleeve, the button end cap is gradually squeezed, and the metal pin at the rear is gradually The gap between the positive electrode guide sheet and the positive electrode of the battery is squeezed step by step; as the inner and outer turntables lock the inner and outer sides of the anti-ridge part, the metal ejector at the rear of the button end cap squeezes the positive electrode guide sheet and the positive electrode of the battery to achieve contact and power supply, and the signal indicator light immediately lights up, indicating that the inner and outer turntables have locked the structure and the wall connecting piece is firmly connected to the structure; at the same time, the outdoor open wire is energized to emit radio electromagnetic waves outward, dispersing the 2.4GHz wireless signal with the digital code of the chip number of the wall connecting piece;

[0032] S6: In building locations where it is convenient to erect ordinary wall ties, pre-buried steel pipe fittings are used at the edge of the floor slab. The pre-buried steel pipe fittings are arranged vertically. Then, a straight sleeve is rotated and inserted into the second threaded connection portion of the inner rod. The interior of the straight sleeve is threaded, and the thread size matches the thread of the second threaded connection portion of the inner rod. Finally, workers use three right-angle fasteners to connect and lock the outer rod, two outer frame poles, and the straight sleeve.

[0033] S7: In the window opening area where it is difficult to set up ordinary wall connecting parts, first, 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 assembly of the outer rod and the inner rod is higher than the windowsill of the window opening; in the plane position, the smooth pipe section clamped by the outer rod and the inner rod is adjusted just 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 disk body so that the first friction pin of the first disk body contacts the outer edge of the window opening; then, the worker holds the second rotating part of the inner turntable and screws the inner turntable into the inner rod through the second threaded connection part of the inner rod; then, the installed specified The support sleeve of the numbered signal transmitting unit is placed on the smooth pipe section sandwiched between the outer turntable and the inner turntable, the support plate of the signal transmitting unit is installed toward the outer turntable, and a numbered indicator sticker is affixed to the support sleeve; finally, the worker uses force to lock the inner and outer turntable bodies of the window hole together, and the metal pin at the rear of the button end cap squeezes the positive electrode guide plate and the positive electrode of the battery to achieve contact and power supply, and the signal indicator light immediately lights up, indicating that the inner and outer turntable bodies have locked the window hole, and the wall connection is firmly connected to the structure; at the same time, the outdoor wired window hole emits radio electromagnetic waves to the outside, dispersing the 2.4GHz wireless signal with the digital code of the wall connection chip number;

[0034] S8: After the wall connection and the main structure of the building are locked, the signal transmission unit windows are powered on, the signal indicator window lights up, and the outdoor wire window transmits radio electromagnetic waves. The construction site safety officer holds the signal receiver and powers it on. The power LED light on the signal receiver lights up. The signal conversion chip built into the signal receiver identifies the multiple digitally coded 2.4GHz wireless signals received, and a lamp bead on the LED array pad corresponding to each code lights up. For a failed wall connection, after locking the location, it is directly inspected and the wall connection is reinforced again.

[0035] S9: After completing the installation and fastening of the scaffolding, workers need to set up 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 range of the positioning holes of the outer rod and the inner rod between the outer scaffolding and the main building. The two hooks of the hook hook the holes on the perforated belt to connect the multiple wall connecting parts in pairs. Finally, the workers install the safety net, and the middle open part of the safety net is placed just above the perforated belt. When the construction materials and construction waste fall from the side of the floor, the safety net intercepts the falling debris with the support of the taut perforated belt.

[0036] S10: After the external frame is erected, a vertical safety net is erected on the outside of the external frame to completely enclose the external scaffolding; workers insert warning tape inserts into the fixed through-holes of the outer rod of each wall connection piece; then, workers pull out the pull rods on the side of each shaft tube, and the warning tape fixed at the rear of the pull rods is pulled out immediately; then, workers hold the pull rods close to the upper warning tape insert, and insert the pull rods from top to bottom into the arc-shaped notch in the shaft tube shell of the previous warning tape insert to achieve horizontal fixation of the pull rods; the warning tape behind the pull rods is pulled out. Under the interaction of the horizontal fixing force of the pull rod in the arc-shaped notch and the rotational force of the central shaft in the shaft tube, the warning tape maintains a vertical, taut and open state; the pull rod of each warning tape insert is fixed to the arc-shaped notch in the shaft tube shell of the previous warning tape insert; if the warning tape at the corner of the external scaffolding wants to be in a tensioned state, it can be achieved by making a 90° bend with the help of the external frame uprights at the corner of the external scaffolding as corner supports; the warning tape realizes a closed loop state with the entire layer connected end to end.

[0037] From the above, the beneficial effects of the multifunctional wall connecting member for building external scaffolding and the construction method thereof of the present invention are as follows:

[0038] 1. Multifunctional integrated design

[0039] Expansion of composite functions: breaking through the single tie function of traditional wall ties, integrating four functional modules: drone landing pad (capable of carrying 25kg-class drones), safety warning tape anchor point (automatically retractable warning tape), safety flat net reinforcement node (hook connected to high-strength perforated tape), and electronic monitoring terminal carrier (with built-in signal transmission unit).

[0040] 2. Intelligent condition monitoring system

[0041] A mechanical-electronic linkage (button end cap, metal ejector pin, and guide plate) built into the support sleeve automatically activates the circuit when the turntable locks the mechanism with a trigger pressure of ≥0.8N. An encrypted UUID signal (128-bit encoding, including the area code and device ID) is transmitted in real time via a 2.4GHz radio frequency module to broadcast the tightening status of the wall connection. Visual safety monitoring: The signal receiver displays the status of each point using a 36-channel LED array (divided into left and right zones, corresponding to the floor numbers). Failure to illuminate indicates a failure. This improves inspection efficiency by security personnel using the terminal by 80%, eliminating 40% of blind spots that traditionally conceal defects.

[0042] 3. Non-destructive recyclable installation system

[0043] Embedded-free clamping technology: adopts a double-turntable adaptive locking structure (outer / inner turntable + support sleeve), and compresses the elastic support plate by screwing it into the thread to achieve rigid anchoring of walls of different thicknesses (window sills / anti-sills / floor edges).

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

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

[0046] 4. Process conflict resolution and rapid recovery

[0047] Construction-friendly window frames and railings: Temporary removal requires only rotating the inner dial to release the clamping force. After installation, retighten until the signal light illuminates to restore functionality. This eliminates the risk of traditional fastener removal requiring specialized wrenches or workers having to dangle steel pipes for inspection.

[0048] 5. High reliability anchoring in special parts

[0049] Thin-wall reinforcement solution: The turntable and counter-sill interface utilizes staggered friction pins to increase the friction coefficient, compensating for the limited depth of traditional pre-embedded components (only 60-80mm). Zero-damage installation of window openings: The turntable directly clamps the concrete window sill (not the window frame), eliminating 30% of anchor bolt conflicts and eliminating chiseling and rework.

[0050] 6. Improved construction efficiency and safety

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

[0052] The safety flat net has been upgraded in impact resistance: hooks are used to connect the perforated belts to form a tensioning network, which increases the tensile strength and the ability to intercept falling objects.

[0053] Warning tape closed-loop system: The warning tape inserts a scroll spring (rebound angular velocity ≥ 120° / s) to achieve automatic belt recovery, reducing the time required for closed-loop tensioning of the entire layer by 70%. BRIEF DESCRIPTION OF THE DRAWINGS

[0140] Step 1: When receiving the building floor plan, the engineer should keep in mind that the national standard requires the setting of building wall ties to be three steps and three spans. That is, starting from the second floor, different numbers of wall ties need to be set on the side of the building every other floor, and the horizontal spacing between the wall ties shall not exceed 4.5m. The engineer draws a plan for the erection of scaffolding wall ties according to the facade features and plane position of the building, and indicates the points where wall ties need to be set and number them in a certain order, such as: "1-A, 1-B....1-R" is set clockwise on the 2nd floor, "2-A, 2-B....2-R" is set clockwise on the 4th floor, "1-A, 1-B....1-R" is set clockwise on the 6th floor, and "2-A, 2-B....2-R" is set clockwise on the 8th floor; wall ties numbered 1-A on multiple floors use components of signal transmitting unit 6 with the same coding; wall ties numbered 1-B on multiple floors also use components of signal transmitting unit 6 with the same coding, and so on; building parts that are convenient for erecting ordinary wall ties are still erected with ordinary wall ties, and the scaffolding erection workers then erect the external scaffolding according to the engineer's drawings.

[0141] like Figure 27 As shown:

[0142] Step 2: When the external scaffolding is erected to the second floor and the wall connection parts are ready for erection, the worker first rotates the first disk 301 of the outer turntable 3 toward the building to install the outer turntable 3 and the first threaded connection part 101 of the outer rod 1; then, insert the inner rod 2 into the outer rod 1 from the side close to the first threaded connection part 101 of the outer rod 1, and the second threaded connection part 201 of the inner rod 2 is on the same side as the first threaded connection part 101 of the outer rod 1; then, according to the thickness of the building wall or balcony anti-slope (200mm / 250mm), 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 to be about 200mm, and the positioning through hole 102 and the adjustment through hole 202 are aligned; finally, two hooks 8 are used 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 realize the position locking of the outer rod 1 and the inner rod 2.

[0143] like Figure 28 As shown:

[0144] Step 3: After adjusting the outer rod 1 and inner rod 2 assembly, secure it to the positioned outer frame uprights 12 using two right-angle fasteners 11. The outer rod 1 and inner rod 2 assembly is approximately 100 mm higher than the counter-ridge 13. In plan view, the smooth pipe section held between the outer rod 1 and inner rod 2 is adjusted directly above the counter-ridge 13.

[0145] like Figure 29 As shown:

[0146] Step 4: First, the worker grasps the first rotating portion 303 of the outer turntable 3 and rotates it, adjusting the position of the first disk body 301 so that the first friction pin 3012 of the first disk body 301 contacts the side of the anti-ridge portion 13. Then, the worker grasps the second rotating portion 403 of the inner turntable 4 and screws the inner turntable 4 onto the inner insert rod 2 via the second threaded connection portion 201. Next, the support sleeve 5 (200mm wide) with the designated numbered signal transmitter unit 6 installed is placed onto the smooth pipe section sandwiched between the outer turntable 3 and the inner turntable 4. The support plate 501 of the signal transmitter unit 6 is installed toward 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 grasps the second rotating portion 403 of the inner turntable 4 and rotates it clockwise. The inner turntable 4 is screwed into the other side of the anti-slope portion 13 along the second threaded connection portion 201 of the inner rod 2. If the worker finds it difficult to rotate the second rotating portion 403, he or she can insert a section of steel pipe 14 about 1 meter long into a second torque cylinder 4032 and twist it clockwise, so that the inner turntable 4 and the outer turntable 3 lock the inner and outer sides of the anti-slope portion 13. At the same time, when 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 ejector pin 6022 at the rear gradually squeezes the gap between the positive electrode guide plate 604 and the positive electrode of the battery 601. As the inner and outer turntables 4 and 3 lock the inner and outer sides of the anti-slope portion 13, the metal pin 6022 on the rear of the button cap 602 squeezes the positive electrode guide plate 604, establishing contact and energizing the positive electrode of the battery 601. The signal indicator 608 then illuminates, indicating that the inner and outer turntables 4 and 3 have locked the structure, and the wall connector is firmly connected to the structure. Simultaneously, the external open wire 6071 is energized to emit radio electromagnetic waves, distributing a 2.4 GHz wireless signal containing the digital code of the wall connector chip number.

[0149] like Figure 32 、 33 As shown:

[0150] Step six: In the parts of the building where it is convenient to set up ordinary wall connecting parts, such as the edge of the floor. The method of pre-embedded steel pipe fittings 17 at the edge of the floor can still be used. The pre-embedded steel pipe fittings 17 are vertical, and the height above the floor surface is generally 250mm-300mm. Then, the straight sleeve 16 is rotated and inserted into the second threaded connection 201 of the inner rod 2. The straight sleeve 16 is threaded by ordinary steel pipe, and the length of the pipe section is 250mm-300mm; the inside of the straight sleeve 16 is threaded, and the thread size matches the thread of the second threaded connection 201 of the inner rod 2. Finally, the worker uses three right-angle fasteners 11 to connect and lock the outer rod 1, the two outer frame uprights 12 and the straight sleeve 16.

[0151] like Figure 34 As shown:

[0152] Step 7: Window opening 18, where installing ordinary wall ties is more difficult. First, adjust the outer rod 1 and inner rod 2 assembly, and then use two right-angle fasteners 11 to adjust and secure the assembly to the positioned outer frame upright 12. The outer rod 1 and inner rod 2 assembly is approximately 150 mm higher than the windowsill of the window opening 18. In planar position, the smooth pipe section clamped by the outer rod 1 and inner rod 2 is adjusted just above the windowsill of the window opening 18. Then, the worker grasps the first rotating portion 303 of the outer turntable 3 and rotates it, adjusting the position of the first disk body 301 so that the first friction pin 3012 of the first disk body 301 contacts the outer edge of the window opening 18. Next, the worker grasps the second rotating portion 403 of the inner turntable 4 and screws the inner turntable 4 onto the inner rod 2 through the second threaded connection portion 201 of the inner rod 2. Next, the support sleeve 5 (200mm wide) with the signal transmitting unit 6 installed with the designated number is placed on 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 installed toward the outer turntable 3, and a numbered indicator sticker is affixed to the support sleeve 5. Finally, the worker uses force to lock the inner and outer turntables 4 and 3 together with the inner and outer sides of the window opening 18. The metal pin 6022 at the rear of the button end cap 602 squeezes the positive electrode guide plate 604 and the positive electrode of the battery 601 to achieve contact and power. The signal indicator light 608 then lights up, indicating that the inner and outer turntables 4 and 3 have locked the window opening 18, and the wall connection is firmly connected to the structure. At the same time, the outdoor cable 6071 emits radio electromagnetic waves outward, dispersing the 2.4GHz wireless signal with the digital code of the wall connection chip number (effective coverage radius is 100m, the signal intensity will be attenuated when passing through a single layer of concrete floor, and the signal intensity will basically disappear when passing through two layers of concrete floor).

[0153] like Figure 35 、36 、37 as shown:

[0154] Step 8: After the wall ties are securely fastened to the main structure, the signal transmission units 6 are powered on, the signal indicator lights 608 illuminate, and the outdoor wires 6071 begin emitting radio electromagnetic waves. For a six-story building, for example, the wall ties are set on even-numbered floors 2, 4, and 6, and the safety officer's inspection floors are similarly even-numbered floors 2, 4, and 6. The site safety officer holds the signal receiver 7 and powers it on, causing the power LED 706 on the receiver 7 to illuminate. The receiver 7 has a built-in signal conversion chip 705, which identifies multiple digitally coded 2.4GHz wireless signals received. Each code corresponds to a specific LED 7081 on the LED array pad 708 that illuminates. For example: the safety officer inspects the tightness of the wall ties on the 2nd floor, focusing on the lighting of the red LED lamp beads 7081 from 1-A to 1-R on the left side of the panel 702, and finds the red LED lamp beads 7081 that are not lit. By looking up the symbols 1-A to 1-R on the panel 702, the scaffolding erection plan can be used to locate the number and position of a failed wall tie; the safety officer inspects the tightness of the wall ties on the 4th floor, focusing on the lighting of the red LED lamp beads 7081 from 2-A to 2-R on the right side of the panel 702, and finds the red LED lamp beads 7081 that are not lit. By looking up the symbols 2-A to 2-R on the panel 702, the scaffolding erection plan can be used to locate the number and position of a failed wall tie. Similarly, when an administrator inspects the sixth floor, they focus on the LEDs 7081 labeled 1-A through 1-R on the left side of panel 702. A security officer inspects the eighth floor, focusing on the LEDs 2-A through 2-R on the right side of panel 702. For a failed wall tie, after identifying its location, they can directly inspect and reinforce it. Security officers patrol the floors along the main axis of the building to prevent signal loss at certain inspection points due to differences in wall layout. Therefore, security officers must inspect specific routes along each floor to facilitate signal reception.

[0155] like Figure 38 、 39 、40 as shown:

[0156] Step 9: After completing the installation and fastening of the scaffolding, workers need to install safety nets 20 every three floors between the exterior scaffolding and the main structure. The safety nets 20 are designed to catch falling construction materials and debris from the sides of the floors, preventing them from injuring workers working on the exterior scaffolding. They also provide a sense of psychological security for workers working near the edges of the building. Traditional safety nets 20 have very limited tensile and impact strength, often breaking due to being unable to catch large falling building materials. The present invention incorporates hooks 8, which are positioned within the positioning holes 102 between the outer rod 1 and the inner rod 2, located between the exterior scaffolding and the main structure. The two hooks 802 of the hooks 8 are designed to engage the holes in the perforated strip 19. The perforated strip 19 is a strip with a certain degree of toughness and strength, and its holes can be fixed to the hooks 802 of the hooks 8, thereby connecting multiple wall ties in pairs. The holes in the perforated tape 19 are placed on the two hooks 802 of the hook 8, ensuring that the tape 19 remains relatively straight. On-site, wire can be used instead of the perforated tape 19, wrapped around the two hooks 802 of the hook 8 to achieve the same effect. Finally, workers install the safety net 20, with its central open area positioned directly above the perforated tape 19. When falling construction materials and debris from the floor are blocked by the taut perforated tape 19, the safety net 20 significantly enhances its ability to intercept falling debris and is less susceptible to damage.

[0157] like Figure 41 、 42 , 43 as shown:

[0158] Step 10: After the external scaffolding is erected, a vertical safety net 21 is installed outside the scaffolding to completely enclose the scaffolding. Typically, a warning line is installed every three floors to distinguish the height of the external scaffolding and provide a warning. The procedure is as follows: A worker inserts a warning tape insert 9 into the fixing hole 103 of the outer rod 1 of each wall tie. Afterwards, the worker forcefully pulls out the tie rod 904 on the side of each shaft 903, which in turn pulls out the warning tape 9035 secured to the rear of the tie rod 904. Next, the worker holds the tie rod 904 close to the upper warning tape insert 9 and inserts it downwards into the arcuate notch 90311 in the shaft housing 9031 of the previous warning tape insert 9, securing the tie rod 904 horizontally. The warning tape 9035 behind the tie rod 904 remains vertically taut and stretched due to the interaction of the horizontal securing force of the tie rod 904 and the rotational force of the central axis 9032 within the shaft 903. In this manner, the tie rod 904 of each warning tape insert 9 is secured to the arcuate notch 90311 in the shaft housing 9031 of the previous warning tape insert 9. If the warning tape 9035 at the corner of the external scaffolding is to be tensioned, the external frame uprights 12 at the corner of the external scaffolding can be bent 90 degrees as a corner support. Therefore, the warning tape 9035 can be in a closed loop state with the entire layer connected end to end.

[0159] like Figure 44 、 45 As shown in Figure 46, the use of drones 22 in engineering projects is becoming more and more common. When additional surveillance cameras are needed in blind spots of project management and monitoring, drones 22 can be used as low-cost supplementary camera equipment for project filming and monitoring. The battery life of drones 22 is generally about half an hour. The quadcopter 2201 and camera 2202 of drone 22 are the main power-consuming devices of the drone, especially the quadcopter 2201, which accounts for 80% of the power consumption of the drone when in operation. However, when the quadcopter 2201 of drone 22 is in the off state and only the camera 2202 of the drone is running to shoot and transmit images, the battery of the drone can achieve a battery life of about 5 hours, which can achieve long-term monitoring. The specific installation method is that the outer rod 1 of the external frame wall member and the parking platform 10 are connected by inserting the warning tape plug 9. The parking platform 10 is generally installed at a higher position of the external scaffolding and in the monitoring blind spots around the project. When it is necessary to monitor and shoot the area, the drone 22 flies above the parking platform 10, adjusts the position of the camera 2202, and then slowly descends to the position of the H-shaped groove 10022 of the parking platform 10. Finally, the four-axis propeller 2201 is turned off, and only the camera 2202 is operated to achieve shooting or monitoring.

[0160] like Figure 47 、48 As shown, the multifunctional wall connection components of the building exterior scaffolding of the present invention are relatively convenient to install, remove, and restore. When the on-site construction reaches the stage of installing the railing 23, the wall connection components of the balcony anti-slope portion 13 need to be temporarily removed. The worker only needs to rotate the inner turntable 4 and unscrew it from the second threaded connection portion 201 of the inner rod 2, then remove the support sleeve 5; then install the railing 23 on the anti-slope portion 13; finally, axially insert the support sleeve 5 from the inner rod 2 and insert it laterally into the gap between the lower crossbar of the railing 23 and the balcony anti-slope portion 13, and hang it on the inner rod 2. Then, rotate the inner turntable 3 and screw it in from the second threaded connection portion 201 of the inner rod 2, firmly clamping the balcony anti-slope portion 13 from both sides. Then, screw the inner turntable 3 in until the signal indicator 608 of the signal transmitting unit 6 of the support sleeve 5 lights up. When the window opening 18 on site needs to be installed with the window frame 24, the wall connection of the window opening 18 needs to be temporarily removed. The worker only needs to rotate the inner turntable 4 and unscrew it from the second threaded connection portion 201 of the inner rod 2, then remove the support sleeve 5. The window frame 24 is then installed and secured on the window opening 18. Finally, the support sleeve 5 is hung from top to bottom on the inner rod 2. The inner turntable 3 is then rotated and screwed in from the second threaded connection portion 201 of the inner rod 2, firmly locking the window opening 18 from both sides. The inner turntable 3 is then screwed 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, as a construction site safety officer, there are mainly two concentrated stages in checking whether the wall ties are installed firmly. The first stage: the external scaffolding is completed and the wall ties are installed for the first time. The construction site safety officer patrols the floor where the wall ties are installed, holding the signal receiver 7, and observes the lighting status of the lamp beads 7081 of the signal receiver 7 to confirm the location of the wall ties that need secondary inspection and reinforcement. After the work is completed, the safety officer can remove the battery 601 of the signal transmitting unit 6. The second stage: during the installation stage of the window frame 24 and the railing 23, the safety officer reinstalls the battery 601 into each signal transmitting unit 6. After the workers have safely completed the installation of the window frame 24 and the railing 23 and restored the wall ties, they finally hold the signal receiver 7 for inspection.

[0162] like Figure 50 As shown, when the external scaffolding needs to be dismantled due to the progress of the project, all parts of the wall tie of the present invention can be recycled. After returning to the factory for cleaning and simple maintenance, they can be put into use as wall ties in the next external scaffolding project, realizing recycling and amortization of construction cost.

[0163] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
