Description

Technical Field

[0001] This utility model relates to the field of disc-lock scaffolding, specifically a ring screw wall-connecting device for disc-lock scaffolding in construction. Background Technology

[0002] Disc-lock scaffolding is a new type of building support system. Its core feature is the welding of perforated connecting discs to the uprights, which quickly fix horizontal and diagonal bars through pin connections. This design gives it structural stability and high load-bearing capacity. The load-bearing capacity of a single upright is much higher than that of traditional scaffolding. At the same time, its modular design significantly improves the efficiency of assembly and disassembly, saving time.

[0003] Currently, most scaffolding and wall connection structures involve installing pre-embedded steel pipes on the wall and using fasteners to connect and fix the steel pipes to the scaffolding. However, this installation structure has a problem: the pre-embedded steel pipes are not easy to dismantle, and there are problems with loading and unloading. In view of this, the inventor urgently needs to design a scaffolding wall connection structure to improve the ease of scaffolding assembly. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a ring screw wall tie device for building disc-lock scaffolding, so as to solve the technical problem of poor assembly convenience of traditional scaffolding wall ties.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ring screw wall-connecting device for disc-lock scaffolding in construction, comprising a scaffolding upright, wherein a connecting pipe is assembled and connected to the scaffolding upright via a connecting fastener, and a connecting sleeve is welded to the side of the connecting pipe near the wall. A wall edge component is installed on the outer side of the wall, and a wall embedding component is pre-embedded on the inner side of the wall edge component. A screw is threaded into the wall embedding component, and a connecting ring is fixedly provided at the end of the screw. A connecting sleeve passes through the inner side of the connecting ring.

[0006] By adopting the above technical solution, screws are screwed into the embedded parts, and then the connecting sleeve is fitted into the connecting ring. This operation is very intuitive and quick, requiring no special tools or welding work, which significantly reduces labor intensity and time costs. At the same time, it effectively solves the problems of component reuse and wall protection. During disassembly, the screw and connecting rod system can be removed without damage simply by reversing the operation. These standard components can be reused in the superstructure or other projects, making them highly economical.

[0007] Furthermore, the connecting sleeve has an overall "L" shape structure, which is suitable for lateral connecting pipes and screw assembly connections.

[0008] By adopting the above technical solution, the "L"-shaped bend forms a natural lever arm, which allows the horizontal load from the scaffolding to be transferred more smoothly to the connecting ring and the wall through the connecting pipe, reducing stress concentration at the connection point, thereby improving the durability and reliability of the entire wall connection device under repeated stress.

[0009] Furthermore, the embedded wall component is fixed to the inner side of the wall edge component with an inclined structure, and its outer end is inclined upward.

[0010] By adopting the above technical solution, the inclined embedded wall component makes the axis of the screw screwed into it form an angle with the horizontal plane. When the scaffolding is subjected to outward pushing force, this inclined angle can effectively decompose part of the tension into pressure that is more favorable to the concrete, improve the stress state of the embedded component in the concrete, enhance its pull-out resistance, and thus improve the safety reserve of the wall connection point.

[0011] Furthermore, the connecting pipe is set perpendicular to the scaffold uprights.

[0012] By adopting the above technical solution, the connecting pipe becomes a purely tension or compression member. When the scaffolding undergoes horizontal displacement, the force will be transmitted to the uprights and walls along the axis of the connecting pipe in the shortest and most direct path, minimizing the additional bending moment caused by the angle of inclination. This ensures that the wall tie can fully exert its rigid support function and effectively restrain the lateral displacement of the scaffolding, which is crucial for maintaining the overall stability of the high-rise structure.

[0013] Furthermore, the connecting sleeve is inserted into one end of the connecting pipe and welded in place.

[0014] By adopting the above technical solution, the welding connection creates a continuous metal fusion interface, making the connecting sleeve and the connecting pipe an integral whole. The force flow is smoothly transmitted, avoiding the gaps and loosening risks that may exist when using threaded connections or pin connections. This ensures that the wall tie system has extremely high rigidity and durability under dynamic loads, which is indispensable for the precise control of scaffold displacement.

[0015] Furthermore, both the connecting pipe and the connecting sleeve are made of Q235B carbon structural steel.

[0016] By adopting the above technical solutions, Q235B steel has a clear yield strength, and its good plasticity and toughness can effectively withstand the impact and vibration loads during the use of scaffolding, preventing brittle failure and providing basic material protection for construction safety.

[0017] In summary, the present invention has the following main advantages: This utility model uses a connecting pipe, connecting sleeve, and screws. During installation, simply screw the screw with the connecting ring into the embedded wall component, and then put the connecting sleeve welded to the end of the connecting pipe into the connecting ring. This process simplifies the traditional welding or complex fastening procedures, making the operation quick and saving time. At the same time, it effectively reduces damage to the wall and the overall cost. During disassembly, the screw and connecting pipe system can be retrieved in reverse without damage for subsequent reuse. It is highly economical, and the pre-embedded wall component is small in size, leaving a small and neat repair surface after removal, reducing the risk of wall damage and leakage.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In this embodiment: A type of ring screw wall-connecting device for disc-lock scaffolding in construction, such as Figure 1 As shown, it includes scaffolding uprights 5, and connecting pipes are assembled and connected to the scaffolding uprights 5 via connecting fasteners 6. A connecting sleeve 3 is welded to the side of the connecting pipe 2 closest to the wall. A wall edge component 4 is installed on the outside of the wall, and a wall embedding component 7 is pre-embedded on the inside of the wall edge component 4. A screw 1 is threadedly connected in the wall embedding component 7, and a connecting ring 8 is fixedly installed at the end of the screw 1. A connecting sleeve 3 passes through the inside of the connecting ring 8.

[0022] Screws are screwed into the embedded parts, and then the connecting sleeve is fitted onto the connecting ring. This operation is very intuitive and quick, requiring no special tools or welding work, which significantly reduces labor intensity and time costs. At the same time, it effectively solves the problems of component reuse and wall protection. During disassembly, the screw and connecting rod system can be removed without damage simply by reversing the operation. These standard components can be reused in the superstructure or other projects, which is economical. The embedded wall parts 7, which are embedded in the wall edge parts 4, are permanently retained. Their volume is much smaller than that of traditional embedded steel pipes. The interface left after removal is neat and easy to repair with mortar, which greatly reduces the damage to the surface of the main building structure and the risk of subsequent leakage, achieving a unity of construction convenience and building integrity.

[0023] See Figure 1The connecting sleeve 3 has an overall "L" shape structure, which is adapted to the horizontal connecting pipe 2 and the screw 1 for assembly and connection. The "L" shaped bend forms a natural lever arm, which allows the horizontal load from the scaffold to be transferred more smoothly to the connecting ring 8 and the wall through the connecting pipe 2, reducing stress concentration at the connection point, thereby improving the durability and reliability of the entire wall connection device under repeated stress. At the same time, this configuration has significant process adaptability and ease of operation. It allows the opening of the connecting sleeve 3 to be naturally and vertically aligned with the connecting ring 8. Workers can easily complete the insertion without having to forcefully bend or adjust the angle of the horizontal connecting pipe 2, reducing the installation difficulty and the requirements for operational precision.

[0024] See Figure 1 The embedded wall component 7 is fixed to the inner side of the wall edge component 4 with an inclined structure, and the outer end is inclined upward. The inclined embedded wall component 7 makes the axis of the screw 1 screwed into it form an angle with the horizontal plane. When the scaffold is subjected to outward pushing force, this inclined angle can effectively decompose part of the tension into pressure that is more beneficial to the concrete, improve the stress state of the embedded component in the concrete, enhance its pull-out resistance, thereby improving the safety reserve of the wall connection point. At the same time, it optimizes the construction operation space, avoids interference with the wall edge component 4, and makes the construction process smoother.

[0025] See Figure 1 The connecting pipe 2 is perpendicular to the scaffold upright 5, making the connecting pipe 2 a purely tension or compression member. When the scaffold undergoes horizontal displacement, the force will be transmitted to the upright and wall along the axis of the connecting pipe in the shortest and most direct path, minimizing the additional bending moment caused by the angle of inclination. This ensures that the wall tie can fully exert its rigid support function and effectively restrain the lateral displacement of the scaffold, which is crucial for maintaining the overall stability of the high-rise structure. At the same time, this standardized and regular geometric relationship greatly facilitates the installation and quality control on the construction site. Workers have a clear and intuitive reference standard when installing the connecting fastener 6, which can be easily checked by simple visual inspection or a square, effectively reducing the problem of decreased load-bearing performance caused by installation angle deviation.

[0026] See Figure 1The connecting sleeve 3 is inserted into one end of the connecting pipe 2 and welded in place. The welded connection creates a continuous metal fusion interface, making the connecting sleeve 3 and the connecting pipe 2 a single unit. This ensures smooth force transmission and avoids the gaps and loosening risks that may exist with threaded or pin connections. It ensures that the wall tie system has extremely high rigidity and durability under dynamic loads. This rigidity is indispensable for accurately controlling scaffold displacement. At the same time, the process of inserting and then welding combines manufacturing convenience and quality control. The connecting sleeve 3 can be pre-inserted into the end of the connecting pipe 2 at a specific angle for precise positioning and then continuous fillet welds can be performed. This ensures that the components produced in batches have consistent dimensions and high-quality connection strength, which is far superior to the temporary and non-standard welding operations that may occur on site.

[0027] See Figure 1 Both connecting pipe 2 and connecting sleeve 3 are made of Q235B carbon structural steel. Q235B steel has a defined yield strength, and its good plasticity and toughness can effectively withstand the impact and vibration loads during scaffolding use, preventing brittle fracture and providing basic material protection for construction safety. At the same time, the choice of Q235B material brings excellent process adaptability and comprehensive cost advantages. The steel has excellent weldability, making it easy to control the quality of the weld joint between connecting sleeve 3 and connecting pipe 2, and preventing cracks from appearing in the weld area, thus ensuring the strength of key nodes.

[0028] The implementation principle of this embodiment is as follows: First, the wall-embedded component 7 is pre-embedded inside the wall edge component 4; during construction, the screw 1 with the connecting ring 8 fixed at the end is screwed into the wall-embedded component 7. Then, the connecting pipe 2, which has been assembled with the scaffold upright 5 through the connecting fastener 6, is positioned so that the "L"-shaped connecting sleeve 3 welded at one end is directly inserted into the inside of the connecting ring 8 that has been fixed on the wall, thereby completing the rigid connection between the scaffold and the wall. When disassembling, it is only necessary to remove the connecting sleeve 3 from the connecting ring 8 and unscrew the screw 1, thus realizing quick assembly and disassembly.
