Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to the external wall chain shaft. Background Technology

[0002] When using exterior wall chain anchors, it is often necessary to understand that exterior wall chain anchors are connecting components used in building curtain walls or wall systems. They are usually made of high-strength materials and are used to fix and support exterior wall panels, ensuring their stability and safety, enhancing the overall structure, improving wind pressure resistance, and preventing panel displacement or detachment. This ensures the durability and safety of the building under extreme weather conditions. The main reason for using exterior wall chain anchors is that they can balance the force on various parts, adapt to minor deformations of the building, simplify the installation process, and improve the overall performance of the exterior wall. They are especially suitable for high-rise buildings or projects with high requirements for earthquake and wind resistance.

[0003] For exterior wall chain lock shafts, the first step is to determine the installation location and take measurements to ensure the chain lock shaft is aligned with the building structure. Then, fix the support or bracket and install the chain lock shaft in the predetermined position. Next, connect the chain and adjust its tension and position to ensure safety and functional requirements. Finally, conduct tests to verify the stability and reliability of the chain lock shaft, and make adjustments as necessary. The entire process requires precise measurements, secure installation, and meticulous debugging to ensure the normal operation and safety of the chain lock shaft on the exterior wall.

[0004] Some existing devices, such as the existing external wall chain shaft devices, have obvious defects. When connecting the chain shaft to the steel mesh, they mostly use simple welding or binding methods. This connection method is greatly affected by factors such as the construction environment and material properties, and is prone to loosening and falling off, resulting in insufficient connection strength. Especially under the long-term exposure to wind, sun, building vibration and other external forces, the stability of the connection part is difficult to guarantee, which in turn affects the safety and durability of the external wall structure and cannot meet the high standards of external wall stability required by modern buildings. Therefore, a dye detection device is proposed to solve the above problems. Utility Model Content

[0005] The external wall chain shaft proposed in this utility model aims to improve the problem of unstable connection between the chain shaft and the steel mesh in some existing devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An external wall chain shaft includes a chain shaft body. Fixed limiting plates are fixedly connected to the upper and lower outer sides of the chain shaft body. A slot is fixedly connected to the upper and lower inner sides of the chain shaft body. The chain body is fixedly connected inside the slot. Limiting mechanisms are provided on the upper and lower inner sides of the slot. Reinforcing mesh is fixedly connected to the left and right adjacent outer sides of the chain shaft body. Fixing mechanisms are provided on the left and right outer sides of the chain shaft body. The limiting mechanism includes a knob. An adjusting component is provided on the top of the knob. A ring block is slidably connected to the outside of the adjusting component. A vertical groove is formed in the internal space of the ring block.

[0028] The external sliding column is slidably connected to the inside of the sliding groove, the external sliding block is slidably connected to the inside of the slot hole, and the external sliding block is slidably connected to the inside of the second slot.

[0029] The above scheme allows the sliding column to slide within the groove, and the sliding block to slide in the slot and the second slot, achieving flexible adjustment and precise positioning. This design makes the fixing mechanism easy to install, stable and reliable, and can adapt to different installation requirements. It effectively ensures the stable operation of the chain shaft and improves the safety and practicality of the overall device.

The sliding design of the fixing block in the vertical groove not only allows for flexible clamping and loosening of the chain body, but also makes the operation simple and easy to control. The cooperation between ring block one and ring block two, as well as the setting of the limiting transverse groove inside ring block two, further enhances the lateral limiting effect of the chain body, effectively preventing the chain from shifting or shaking during operation.

[0032] 2. In this utility model, the cooperation of the sliding column and the sliding groove, the slider and the slot and the second slot allows for flexible position adjustment during installation, ensuring that the connection is adapted to different working conditions. The locking function achieved by the slider sliding into the second slot, and the tight cooperation between the concave cavity and the protrusion in the reinforcement component, ensure the stability and firmness of the connection from two dimensions.

[0048] The fixing mechanism 7 includes a top seat 71, which is the upper structure of the fixing mechanism 7. It is mainly used to connect the steel mesh 6 and provide support for the sliding column 72 and the reinforcing component 74. Multiple sliding columns 72 are fixedly connected to the outer side of the top seat 71. They cooperate with the sliding groove 77 of the base 75 to realize the sliding connection between the top seat 71 and the base 75, which facilitates the position adjustment during installation. Sliding blocks 73 are fixedly connected to the left and right sides of the outer side of the sliding column 72.

The slider 73 slides in the slot 76 and the second slot 78, playing a limiting and locking role, ensuring that the connection between the top seat 71 and the base 75 is stable. The connection method of these components enables the components of the limiting mechanism 5 and the fixing mechanism 7 to work together, ensuring the stability of the chain body 4, enhancing the connection strength between the chain shaft body 1 and the steel mesh 6, and thus improving the overall structural performance of the exterior wall.

[0056] Working principle: When the external wall chain shaft is working, the chain body 4 is installed in the slots 3 on the upper and lower sides inside the chain shaft body 1. Through the knob 51 in the limiting mechanism 5, the knob 51 drives the connecting rod 521 in the adjusting component 52 to move. The fixing block 522 at the top of the connecting rod 521 slides in the vertical groove 54 inside the ring block 53, thereby realizing the limiting adjustment of the chain body 4. At the same time, the sliding of the fixing block 522 in the vertical groove 54 can clamp and loosen the chain body 4. The connecting ring 55 outside the ring block 53 connects to the second ring block 55. The limiting transverse groove 57 inside the second ring block 56 limits the chain body 4 laterally. The fixed limiting plates 2 on the upper and lower sides outside the chain shaft body 1 ensure its stability inside the wall, thereby moving the first ring block 53 and the second ring block 56. The limiting transverse groove 57 inside the second ring block 56 limits the chain body 4 laterally.

[0057] The chain shaft body 1 and the steel mesh 6 are connected by a fixing mechanism 7.

During installation, the sliding column 72 slides in the sliding groove 77 of the base 75, and the slider 73 on the sliding column 72 slides in the slot 76 to adjust its position. After the adjustment is in place, the slider 73 slides into the second slot 78 to lock the top seat 71 and the base 75. At the same time, the concave cavity 741 and the protrusion 742 in the reinforcing component 74 cooperate to enhance the connection strength between the top seat 71 and the base 75. Through the cooperation of the sliding column 72 and the sliding groove 77, the slider 73 and the slot 76 and the second slot 78, a stable connection between the chain shaft body 1 and the steel mesh 6 is achieved.
