Description

Technical Field

[0001] This invention relates to the field of wall tie technology, and in particular to a wall tie for scaffolding on the exterior walls of a frame structure and its construction method. Background Technology

[0002] With the rapid development of high-rise and super high-rise buildings, frame structures are widely used due to their flexible spatial layout and good seismic performance. In frame structure construction, external wall scaffolding serves as a crucial high-altitude work platform and safety protection facility; its erection quality directly affects the personal safety of construction workers and the progress of the project. Scaffolding is reliably connected to the main structure through wall ties to resist lateral forces generated by its own weight, construction loads, and wind loads, preventing tilting, swaying, or even collapse. Therefore, the design and construction quality of the wall ties are key to ensuring the stability of the scaffolding system. Existing wall ties still have many shortcomings in practical applications. Traditional wall ties require the installation of pipe clamps for fixing them. Currently, the pipe clamps are installed directly on the outer wall of the wall tie and locked with bolts and nuts. However, since the outer wall of the wall tie is relatively smooth, the pipe clamps alone cause them to slide relative to the wall tie, which makes it impossible to guarantee the axial stability of the pipe clamps relative to the wall tie. To address the aforementioned shortcomings, there is an urgent need to develop a reliable wall tie member and its construction method that can ensure the stability of the connection between the pipe clamp and the wall tie member, so as to improve the overall stability and construction safety of scaffolding. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wall tie member for scaffolding of frame structures and its construction method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A wall tie member for scaffolding on the exterior wall of a frame structure includes a member body fixed to the wall using an installation component and a rotating mechanism. The member body has a three-section structure, including member body one, member body two, and a collar. Member body one and collar are integrally formed, member body two is welded and fixed to a fixing plate, and member body one is connected to member body two by a plug-in method through collar. A pipe clamp is installed on the outer circumference of collar by fitting.

[0005] As a further embodiment of the present invention: the mounting component includes a fixing plate, a bolt, and an embedded part. The embedded part is fixed to the inner wall of the assembly hole opened on the surface of the wall, and the bolt passes through the assembly hole opened on the surface of the fixing plate and is threadedly connected to the embedded part.

[0006] As a further embodiment of the present invention: a fixing plate 1 is welded to the top of the main body 2 of the rod, and a fixing plate 2 is welded to the top of the main body 1 of the rod. The mounting holes opened on the fixing plate 1 and the fixing plate 2 are locked and limited by locking components.

[0007] As a further embodiment of the present invention: the locking component includes a second bolt and a nut threadedly connected to the second bolt. After the second bolt is inserted into the mounting holes on the second fixing plate and the first fixing plate, the threaded connection between the nut and the second bolt is used to fix the first rod body and the second rod body.

[0008] As a further embodiment of the present invention: an adjusting ring is fitted into the outer circumference of the collar, and the adjusting ring is used to adjust the lateral spacing between the pipe clamp and the wall.

[0009] As a further embodiment of the present invention: a mounting shell is fixed to one side of the outer wall of the fixing plate 2 by screws, a monitoring rod is slidably connected to one end of the mounting shell, a mounting plate is fixed to one end of the monitoring rod by screws, a pressure sensor is fixed on the mounting plate, and a spring is fixed between the outer wall of the pressure sensor and the inner wall of the mounting shell.

[0010] As a further aspect of the present invention: the elastic force of the spring keeps the monitoring rod in contact with the wall, and the pressure sensor detects the pressure changes caused by the compression or stretching deformation of the spring in real time to detect the external force on the monitoring rod.

[0011] As a further embodiment of the present invention: the rotating mechanism includes a universal joint one and a universal joint two, which are connected by a straight pipe, and the end of the universal joint one away from the straight pipe is fixedly connected to a fixed plate. One end of the rod body two is welded with an intermediate plate, and the end of the universal joint two away from the straight pipe is fixedly connected to the intermediate plate.

[0012] As a further aspect of the present invention: the pipe clamp is provided with two sets of fasteners, which are used to fix the steel pipes of the scaffold after the main body of the pole is fixed to the wall.

[0013] A construction method for wall ties used in scaffolding for exterior walls of frame structures includes the following steps: S1: On the exterior wall of the frame structure, drill holes according to the design location to form assembly holes, and anchor the embedded parts into the hole wall; S2: Align the mounting holes on the fixing plate with the embedded parts, insert the bolts into the mounting holes of the fixing plate and connect them to the embedded parts by thread, and tighten them gradually to fix the fixing plate to the wall surface. S3: Use the rotating mechanism to adjust the tilt angle of the main body of the rod, put the pipe clamp into the outer circumference of the collar, and then insert the collar into the second main body of the rod in the horizontal direction so that the collar and the second main body of the rod form a plug-in fit. S4: Align the part of the main body of the rod that is integrally formed with the collar with the collar and insert it into place; S5: Align the mounting holes on fixing plate one and fixing plate two, insert bolt two in sequence, and tighten the nut at the end of bolt two to lock and limit the movement between rod body one and rod body two; S6: Based on the required lateral distance between the scaffold steel pipe and the wall, select an adjusting ring of appropriate thickness and fit it onto the outer wall of the collar to adjust the distance between the pipe clamp and the wall; S7: Place the scaffolding steel pipe into the two sets of mutually perpendicular couplers of the pipe clamp to complete the fixing of the steel pipe to the wall tie; S8: Fix the mounting shell to one side of the fixing plate with screws, insert the monitoring rod into the mounting shell, so that the spring is located between the monitoring rod and the mounting shell, and use the spring force to make the monitoring rod stick tightly to the wall; S9: Start the pressure sensor for initial calibration. By monitoring the pressure changes caused by the compression or tension of the spring, the external force on the wall tie rod is detected in real time. When the pressure value is abnormal or exceeds the preset threshold, reinforcement or adjustment measures are taken in time.

[0014] Compared with the prior art, the present invention provides a wall tie member for scaffolding of exterior walls of frame structures and its construction method, which has the following beneficial effects: By using the three-section main body of the member and the collar for insertion and connection, as well as the locking and limiting of the bolts and nuts, the wall tie members are rigidly connected to the wall, which effectively shortens the free length of the scaffold uprights, enhances the lateral stiffness of the scaffold, prevents swaying, tilting or collapse, and ensures construction safety.

[0015] Adjustable rings can be fitted into the outer wall of the collar, allowing the position of the pipe clamps to be adjusted according to the lateral distance requirements between the scaffold steel pipes and the wall, adapting to the spatial conditions of different engineering sites and improving construction efficiency and applicability.

[0016] The installation components consist of a fixing plate, bolts, and embedded parts. They are anchored to the wall via threaded connections to ensure that the wall tie rods are firmly fixed and to reduce the risk of structural instability caused by loose connections.

[0017] The pressure sensor senses changes in the external force on the monitoring rod through a spring, and detects the load borne by the wall tie rod in real time. When the pressure is abnormal or exceeds the threshold, it will issue an early warning in time, so as to realize dynamic safety control of the construction process.

[0027] A wall tie member for scaffolding on the exterior walls of a frame structure, such as Figures 1 to 5 As shown, the main body of the rod is fixed to the wall 1 by means of an installation component and a rotating mechanism. The installation component includes a fixing plate 3, a bolt 4 and an embedded part 6. The embedded part 6 is fixed to the inner wall of the assembly hole opened on the surface of the wall 1. The bolt 4 passes through the inner wall of the assembly hole opened on the surface of the fixing plate 3 and is threadedly connected to the embedded part 6 to fix the fixing plate 3 and the wall 1. The main body of the rod and the fixing plate 3 are connected by a rotating mechanism. The main body of the rod is a three-section structure, including a first rod body 5, a second rod body 8, and a collar 9. The first rod body 5 and the collar 9 are integrally formed, and the first rod body 5 is connected to the second rod body 8 by a plug-in method through the collar 9. A pipe clamp 7 is installed on the outer circumference of the collar 9 by a fitting method. The rotating mechanism includes a universal joint 20 and a universal joint 22. The universal joint 20 and the universal joint 22 are connected by a straight pipe 21. The end of the universal joint 20 away from the straight pipe 21 is fixedly connected to the fixed plate 3. One end of the rod body 28 is welded with an intermediate plate 19. The end of the universal joint 22 away from the straight pipe 21 is fixedly connected to the intermediate plate 19. The first rod body 5 and the second rod body 8 are locked and limited by a locking component. The top of the second rod body 8 is welded with a fixing plate 11, and the top of the first rod body 5 is welded with a fixing plate 18. The locking component includes a bolt 13 and a nut 12 threadedly connected to the bolt 13. After the bolt 13 is inserted into the mounting holes on the fixing plate 18 and the fixing plate 11 in sequence, the nut 12 and the bolt 13 are threadedly connected to fix the first rod body 5 and the second rod body 8. Wall ties are crucial load-bearing components in scaffolding projects. Their function is to rigidly or flexibly connect the scaffolding to the walls or columns of the main structure, and to counteract lateral displacements and inward moments caused by the scaffolding's own weight, construction loads, and wind loads through evenly distributed horizontal constraints. During scaffolding erection, wall ties effectively shorten the longitudinal free length of the uprights, significantly improving the lateral stiffness and overall stability of the scaffolding, preventing swaying, tilting, or even collapse. When assembling the main body of the rod, firstly, drill holes in the wall 1 using a drilling machine. After drilling, anchor the embedded part 6 to the wall 1. After anchoring, align the assembly hole on the fixing plate 3 with the embedded part 6. Then, insert bolt 4 along the assembly hole and thread it with the embedded part 6 until bolt 4 and embedded part 6 fix the fixing plate 3 to the wall 1. Then, using the multi-angle rotation characteristics of universal adapter 20 and universal adapter 22, the main body of the rod can be flexibly adjusted from different directions (up, down, left, right) during construction to adapt to different installation environments. Next, after fitting the pipe clamp 7 onto the outer circumference of the collar 9, insert the collar 9 laterally along the second rod body 8. After insertion, align the mounting holes on the intermediate plate 19 and the mounting holes on the first fixing plate 11 with each other. Then, insert the second bolt 13 laterally into the two mounting holes in sequence. Finally, thread the nut 12 and the second bolt 13 together and tighten them. This will limit the end of the pipe clamp 7 to be located between the first rod body 5 and the second rod body 8, preventing the pipe clamp 7 from displacing axially. When it is necessary to fix the steel pipes of the scaffold, the steel pipes of the scaffold are fixed using pipe clamps 7. The pipe clamps 7 are equipped with two sets of fasteners, and the fixing directions of the two sets of fasteners are perpendicular to each other. This allows the steel pipes of the scaffold to be fixed after the main body of the pole and the wall 1 are fixed.

[0028] An adjusting ring 10 is fitted onto the outer circumference of the collar 9, and the adjusting ring 10 is used to adjust the lateral distance between the pipe clamp 7 and the wall 1. When the steel pipes of the scaffolding need to be installed and the distance between them and the wall 1 needs to be limited, the thickness of the adjusting ring 10 can be set accordingly according to the distance. When fixing the pipe clamp 7, the adjusting ring 10 is sleeved on the outer wall of the collar 9. The horizontal straight distance between the pipe clamp 7 and the wall 1 is adjusted by adjusting the adjusting ring 10, thereby adjusting the distance between the steel pipes of the scaffolding and the wall 1.

[0029] The mounting plate 18 is fixed to one side of the outer wall by screws with a mounting shell 15. A monitoring rod 2 is slidably connected to one end of the mounting shell 15. The monitoring rod 2 is fixed to one end of the mounting plate 14 by screws. A pressure sensor 17 is fixed on the mounting plate 14. A spring 16 is fixed between one side of the outer wall of the pressure sensor 17 and one side of the inner wall of the mounting shell 15. The spring force of the spring 16 makes the monitoring rod 2 and the wall 1 fit together. The pressure sensor 17 senses the pressure change caused by the compression or tension deformation of the spring 16 on the mounting plate 14, and detects the external force on the monitoring rod 2 in real time. Then, it can determine whether the load borne by the wall connection member is within the normal range. When the pressure value fluctuates abnormally or exceeds the preset threshold, it can reflect that the connection between the scaffold and the wall 1 is unstable, thereby realizing online monitoring of its stability. Example

[0030] A construction method for wall ties used in scaffolding for exterior walls of frame structures includes the following steps: S1: On the wall 1 of the outer wall of the frame structure, drill holes according to the design position to form assembly holes, and anchor the embedded parts 6 in the hole wall to ensure that they are firmly connected with the wall 1. S2: Align the mounting holes on the fixing plate 3 with the embedded parts 6, insert the bolts 4 into the mounting holes of the fixing plate 3 and thread them into the embedded parts 6, and tighten them gradually to make the fixing plate 3 firmly fixed on the surface of the wall 1. S3: Adjust the tilt angle of the main body of the rod by using the rotating mechanism, put the clamp 7 into the outer circumference of the collar 9, and then insert the collar 9 into the main body of the rod 8 in the transverse direction so that the collar 9 and the main body of the rod 8 form a plug-in fit. S4: Align the integrally formed part of the main body 5 and the collar 9 with the collar 9 and insert it into place; S5: Align the mounting holes on the fixing plate 11 and the fixing plate 2 18, insert the bolts 2 13 in sequence, and tighten the nut 12 at the end of the bolts 2 13 to lock and limit the movement between the main body 1 5 and the main body 2 8. At the same time, the pipe clamp 7 is restricted between the two rods to prevent axial displacement. S6: Based on the required lateral distance between the scaffold steel pipe and the wall 1, select an adjustment ring 10 of appropriate thickness and fit it into the outer wall of the collar 9 to adjust the distance between the pipe clamp 7 and the wall 1, and ensure that the fixed position of the steel pipe meets the design requirements. S7: Place the scaffolding steel pipe into the two sets of mutually perpendicular couplers of the pipe clamp 7 to complete the fixing of the steel pipe and the wall tie, so that the scaffolding and the wall 1 form a stable connection. S8: Fix the mounting shell 15 with screws on one side of the fixing plate 2 18, insert the monitoring rod 2 into the mounting shell 15, so that the spring 16 is located between the monitoring rod 2 and the mounting shell 15, and use the elastic force of the spring 16 to make the monitoring rod 2 stick tightly to the wall 1. S9: Start pressure sensor 17 for initial calibration. By monitoring the pressure changes caused by the compression or tension of spring 16, the external force on the wall tie members is detected in real time. When the pressure value is abnormal or exceeds the preset threshold, reinforcement or adjustment measures are taken in time to ensure the structural stability of the scaffolding throughout the construction process.

Various modifications and variations can be made to this application by those skilled in the art.
