Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to a curtain wall column welding and fire connection system and its usage method. Background Technology

[0002] In the construction industry, welding slag is generated during the welding of steel structure columns and curtain wall mullions. Slag ignition is a serious safety accident that can lead to severe consequences. Slag ignition refers to a fire that occurs during the welding process of steel structure columns and curtain wall mullions when, due to improper handling of the slag, it comes into contact with flammable materials or spontaneously combusts under gravity or at high temperatures. Such accidents not only cause significant losses to the construction site but also threaten the lives of workers.

[0003] Traditional welding slag collection systems, due to gravity and the lack of a suitable suspension point, can only be installed at the bottom of the welding area. When the welding area is high, the radius of the falling slag is large, rendering traditional systems ineffective in collecting the slag splashed from above. The sparks and high temperatures generated during welding can lead to burns, fires, and other safety risks. Traditional welding slag collection systems are also limited by the working environment, with only one fixed form. They are difficult to implement in confined spaces, and their ability to collect slag splashes needs further improvement. Traditional welding slag collection buckets have limited adjustability, many only suitable for a specific column size, resulting in poor versatility. Furthermore, traditional welding slag collection buckets are bulky and cannot be folded for convenient storage. Summary of the Invention

[0038] Furthermore, such as Figures 1-3 As shown, the fireproof cloth 3 can be a single piece applied to the outer surface of the adjustable fire-receiving unit 4, or it can be segmented and placed between two adjacent adjustable fire-receiving units 4. This design provides flexible arrangement options to adapt to different welding operation requirements. When the fireproof cloth 3 is a single piece, its area matches the area of ​​the adjustable fire-receiving unit 4 when it unfolds along the circumference of the circular rail 2, ensuring the fireproof performance of the entire fire-receiving system. When the retractable frame 46 of the adjustable fire-receiving unit 4 unfolds around the circumference of the circular rail 2, the fireproof cloth 3 wraps around the outer periphery of all the second connecting rods 45 and the retractable frame 46, forming a V-shaped arrangement, which helps to concentrate and guide the welding process. The generated sparks and heat; one end of the fireproof cloth 3 is arranged along the outer surface of the second connecting rod 45 towards the direction of the lower circular rail 2, and the other end is arranged along the extension direction of the telescopic frame 46 towards the telescopic joint 461, which helps the fireproof cloth to fit tightly into the fire-receiving system when not in use, reducing the space occupied; the V-shaped bottom end of the fireproof cloth 3 is fixed at the junction of the telescopic frame 46 and the second connecting rod 45, which can ensure that the fireproof cloth remains stable during the deployment and use of the fire-receiving system; the fireproof cloth 3 has multiple pleats parallel to each other from bottom to top along the extension direction of the telescopic joint 461, which not only facilitates storage and folding, but also helps to improve the durability and adaptability of the fireproof cloth.

[0040] Furthermore, such as Figures 1-3 As shown, a series of progressively smaller telescopic joints 461 are nested together to form the telescopic frame 46; the telescopic frame 46 is a rectangular or circular tubular structure; the telescopic joints 461 are also rectangular or circular tubular structures; this design not only provides the necessary strength and stability, but also facilitates manufacturing and assembly; at the connection between two adjacent telescopic joints 461, the outer telescopic joint 461 is provided with a locking hole 462, and the inner telescopic joint 461 is provided with a telescopic bead 463 that matches the locking hole 462; the telescopic bead 463 extends perpendicularly to the surface of the telescopic joint 461; when adjusting the extension of the telescopic joint 461, the telescopic bead 463 is pressed down, and the telescopic joint 461 is pulled outward to adjust. Afterwards, release the telescopic bead 463, allowing it to pop out from the corresponding locking hole 462 to fix the telescopic joint 461. This design allows users to quickly adjust the length of the telescopic joint 461 and fix it quickly after adjusting it to the appropriate position, improving the convenience and efficiency of operation. Through the cooperation of the telescopic bead 463 and the locking hole 462, the length of the telescopic joint 461 can be repeatedly adjusted to adapt to different welding operation requirements. The adjustable design of the telescopic joint allows the entire welding system to be compactly stored when not in use, making it easy to carry and store. The adjustment mechanism of the telescopic joint 461 not only improves the adaptability and practicality of the welding system, but also reduces the labor intensity of users during the adjustment process through its simple operation.

[0041] Furthermore, such as Figures 1-3As shown, one end of the second connecting rod 45 is arc-shaped, which helps to reduce stress concentration and improve the stability of the structure; the other end of the second connecting rod 45 is provided with a hinge hole 451 for connecting with the telescopic frame 46, so as to realize multi-angle rotation of the telescopic frame 46; the arc-shaped end of the second connecting rod 45 is provided with a circular rail hole 452 that matches the lower circular rail 2, allowing the second connecting rod 45 to slide or be positioned on the lower circular rail 2; the end of the second connecting rod 45 away from the circular rail hole 452 is provided with parallel and spaced fixing ears 453 for fixing the second connecting rod 45. The position of the second link 45 is designed to prevent it from deviating when sliding on the circular rail 2; the hinge holes 451 are symmetrically arranged on the two fixed ears 453, which helps to maintain the balance of the second link 45 and ensure its stable movement on the circular rail; the end of the telescopic frame 46 away from the telescopic joint 461 is mounted on the hinge hole 451 by a pin, so that the telescopic frame 46 and the second link 45 can rotate at multiple angles, increasing the adjustment flexibility of the fire-fighting system; the effective fire-fighting area of ​​the fire-fighting system can be further changed by adjusting the telescopic joint 461.

[0042] Furthermore, such as Figures 1-3 As shown, the angle adjustment mechanism 5 includes a pull rod 51 mounted on the telescopic frame 46 and several stop bars 52 mounted on the second connecting rod 45 and corresponding to the pull rod 51. One end of the pull rod 51 is rotatably connected to the telescopic frame 46, allowing the pull rod 51 to rotate freely on the telescopic frame 46, thereby adjusting the angle between the second connecting rod 45 and the telescopic frame 46. The other end of the pull rod 51 is provided with a hook 53 that bends back towards the rotatable connection end, so that the hook 53 can easily engage with different stop bars 52 on the second connecting rod 45. The upper surface of the second connecting rod 45 is provided with a retaining groove 454. The stop bars 52 are parallel within the retaining groove 454. Multiple angles are spaced out; multiple fixing points are provided, allowing users to select different angles as needed; a semi-circular fixing ring is provided on the telescopic frame 46; a connecting hole for connecting the semi-circular fixing ring is provided at one end of the pull rod 51 near the telescopic frame 46; the pull rod 51 can rotate freely on the telescopic frame 46, increasing the flexibility of adjustment; by engaging the hook 53 with different stop bars 52 on the second connecting rod 45, this adjustment mechanism allows users to adjust the angle between the telescopic frame 46 and the second connecting rod 45 according to the specific needs of the welding operation, thereby adjusting the effective contact area to adapt to welding operations of different sizes and shapes. The angle adjustment mechanism of this invention makes the contact operation simple and intuitive, allowing users to easily adjust the angle and area of ​​the contact system as needed, improving work efficiency.

[0044] Furthermore, such as Figures 1-3 As shown, the two circular rails 2 are arranged parallel to each other vertically, including a first semicircle 21 and a second semicircle 22 that can be spliced ​​into a ring, a hinge point 23 located at one end of the first semicircle 21 and the second semicircle 22, and magnetic baffles 24 located on the first semicircle 21 and the second semicircle 22 respectively away from the hinge point 23; the opening and closing of the hinge point 23 allows the upper and lower circular rails 2 to be respectively fitted into appropriate positions on the column 1; the two magnetic baffles 24 on the first semicircle 21 and the second semicircle 22 are attracted together; so that the upper and lower circular rails 2 form a closed circular rail; the magnetic baffles 32 can ensure that the two layers of circular rails 2 form a closed circular rail on the one hand, and prevent the adjustable fire-fighting unit 4 from sliding out of the upper and lower circular rails 2 on the other hand; by adjusting The length of the lead screw 42 on the adjustable welding unit 4 extending towards the column allows the universal pad 41 to abut against the column 1, thus fixing the position of the adjustable welding unit 4 and the curtain wall column 1. Several adjustable welding units 4 rotate around the upper and lower circular rails 2 one revolution through the slip ring 43 and the circular rail hole 452, so that the adjustable welding units 4 are evenly distributed on the two circular rails 2.

This invention provides a flexible, safe and efficient welding system positioning and adjustment mechanism, ensuring that the welding system can be quickly adjusted according to different working environments and needs.

[0045] like Figure 4 As shown, a second aspect of the present invention provides a method for welding and ignition of curtain wall mullions, implemented using the aforementioned curtain wall mullion welding and ignition system, comprising the following steps:

[0046] S1: Based on the dimensions of the curtain wall columns, fabricate a fire-receiving system comprising two layers of circular rails 2, several adjustable fire-receiving units 4, and fireproof cloth 3, and assemble all components; specifically, fix the fireproof cloth 3 onto the second connecting rod 45 and the telescopic frame 46 of the adjustable fire-receiving unit 4; sleeve the slip rings 43 of several adjustable fire-receiving units 4 onto the upper circular rail 2; and sleeve the second connecting rod 45 onto the lower circular rail 2;

[0047] S2: Place the two layers of circular rails 2 on the column 1 at a preset height, rotate the lead screw 42 on each of the adjustable fire-receiving units 4 so that the universal pad 41 at one end of the lead screw 42 abuts against the column 1. By precisely controlling the rotation of the lead screw 42, fine-tune the distance between the universal pad 41 and the column 1 to ensure the accurate positioning of the fire-receiving system and prevent it from sliding down.

[0048] Specifically, the two magnetic stops 24 on the circular rail 2 are separated, opening the hinge point 23; the two semicircles of the circular rail 2 are placed around the column 1 at a suitable height and attracted together by the magnetic stops 24 on the two semicircles, forming a closed circular rail 2; the lead screw 42 on each of the adjustable fire-receiving units 4 is rotated, causing the universal pad 41 at one end of the lead screw 42 to move closer to the column 1. When the universal pad 41 abuts against the surface of the column 1, stable positioning between the fire-receiving system and the column 1 can be achieved; by precisely controlling the rotation of the lead screw 42, the distance between the universal pad 41 and the column 1 can be finely adjusted to ensure accurate positioning of the fire-receiving system and to ensure that the fire-receiving system will not fall off under gravity.

[0049] S3: Spread out several adjustable fire-receiving units 4 along the circumference of the circular rail 2. Adjust the relative position of the pull rod 51 and the stop bar 52 on the angle adjustment mechanism 5 according to the actual needs of the site.
