Description

Technical Field

[0001] The invention relates to the technical field of steel structure buildings, and more particularly to a quick connection assembly for steel structure buildings. Background Art

[0002] As a traditional form of residence for the Mongolian people, the yurt plays an important role in nomadic life with its unique structural design and flexibility. However, with the development of modern construction technology and the improvement of people's requirements for living quality, the traditional yurt has gradually revealed its limitations in materials, structure, and installation and disassembly methods. In recent years, especially, light steel structure has been widely used in yurt construction due to its advantages of high strength, light weight, corrosion resistance, and easy processing. However, the diversity of the skeleton design of the light steel structure yurt and the complexity of installation and disassembly have become key factors restricting its further promotion and application.

[0003] Existing light steel structure yurts are mainly composed of main steel structure, enclosure panels (such as color steel plates), canopies (such as galvanized iron sheets), doors and windows, etc. The main steel structure usually uses grooved steel pipes welded into a mesh truss frame. Although this structure has high bearing capacity and stability, it has many skeleton components and complex connection nodes, making the installation and disassembly process cumbersome and time-consuming.

[0004] During the installation process, the steel frame needs to be fixed to the ground first, and then accurately assembled and welded according to the design drawings, and the various components are connected and adjusted to ensure the stability and safety of the yurt. However, due to the large number of components and complex connections, errors are prone to occur during the installation process, affecting the stability and aesthetics of the overall structure. At the same time, it is also necessary to disassemble each component one by one during disassembly, which is not only time-consuming and labor-intensive, but also easy to cause damage to the components. Due to the complexity of installation and disassembly and the long construction period, it is difficult to meet the needs of rapid construction and dismantling, especially in tourist attractions, temporary residences and other occasions. The complex installation and disassembly process also increases the manpower and time costs, making the overall cost of the light steel structure yurt high.

[0005] In summary, it is particularly important to effectively solve the complexity and inefficiency of the installation and disassembly of existing yurts and promote the widespread application and development of yurt buildings in modern society. In view of this, we propose a steel structure building quick connection component. Summary of the invention

[0019] 1. The present invention improves the connection components of existing steel structure buildings. A quick connection structure is provided on the Hana structure arranged in a ring-shaped and equidistant pattern at the top of the base. The Uni structure is quickly plugged in through the quick connection structure, thereby solving the problem that the traditional Uni structure requires multiple bolts to fix, which is relatively cumbersome. The other end of the Uni structure is connected to the Nao structure through the rafter structure, and the Nao structure is used to lock multiple Hana structures at equal intervals in a ring-shaped pattern through the Nao structure, making the connection simple and quick, without the need for complicated welding or bolt fixing, and greatly shortening the installation time.

It is particularly suitable for temporary residences or tourist attractions that need to be built quickly, and also makes the disassembly process simple, which can be easily disassembled and moved, meeting the flexibility requirements of nomadic life or temporary residences.

[0020] 2. The first quick connector and the second quick connector in the present invention have the same structure components and are compatible with each other. When plugging in, the plug block is inserted into the slot, and the rotary lock plate on the rotating groove of the plug block rotates. During the insertion process, the two rotary lock plates squeeze each other, causing the rotating ends of the two rotary lock plates to rotate in the rotating groove in a cylindrical shape. After rotation, the two modules are locked. When it is necessary to disassemble, the other end of the rotary lock plate is turned so that the rotating end of the rotary lock plate rotates in the rotating groove in a cylindrical shape in the opposite direction until the straight end of the semi-cylinder rotates to a vertical state, so that the two plug blocks can be pulled out of the slot. The quick connection assembly also makes the disassembly process simple. The steel structure skeleton can be easily disassembled and moved without cutting or welding, so that the steel structure material can be recycled, reducing resource waste and environmental pollution.

[0021] 3. In the present invention, the unni rod and the splint are inserted between a group of symmetrically arranged inserts, and are sleeved onto the ring sheet of the outer ring of the sleeve, so that the lock hole is aligned with the insert hole, and the rafter structure is inserted into the lock hole and the insert hole through the linkage unit and the sliding unit to achieve locking. When the unni rod and the splint of the present invention are connected to the sleeve structure, positioning and alignment are relatively quick and the installation positioning is accurate, and there is no need to repeatedly calibrate the position, thereby ensuring that the connection between the unni and the sleeve is more stable, improving the stability of the overall structure, and enhancing its ability to resist natural disasters such as wind and snow outdoors.

[0022] 4. In the present invention, the hexagonal wrench is inserted into the locking structure through the bottom plate, the rotating locking structure drives the rotating ring body to rotate, the rotating ring body drives the inner tooth groove to rotate, the inner tooth groove engages with the gear to drive a plurality of gears arranged in a ring with equal spacing to rotate synchronously, the gear engages with the rack to make a plurality of racks slide synchronously in the slide groove, the rack drives the extrusion block A at the outer end to extrude the rafter structure so that the rafter structure is inserted into the lock hole and the plug hole to realize one-time synchronous locking connection of multiple unis and sets, which greatly improves the efficiency of installation and disassembly, making it an ideal choice for emergency rescue and building shelters, and the recycling rate after rescue is extremely high, which is in line with the concept of sustainable development. Reduce the consumption of natural resources and environmental pollution, and achieve the goal of green building.

[0023] 5. In the present invention, a ring sleeve is arranged at the bottom end of the outer ring of the sleeve, a convex groove is opened in the ring sleeve, and a convex groove is opened on the rotating block, so that the rotating block is rotatably arranged in the ring sleeve, and five gradient grooves are opened in a ring shape with equal intervals on the rotating block, and a pulley is movably arranged on the gradient groove. The gaps between the two ends of the gradient groove and the convex groove of the ring sleeve are different. When the hexagonal wrench is inserted into the rotating block to drive it to rotate, the pulley squeezes the end with a smaller gap of the gradient groove, so that the rotating block can only rotate in one clockwise direction, and the other clockwise direction will be locked due to the gradient groove squeezing the pulley. The locking function can ensure a more stable connection and prevent loosening or falling off due to wind, vibration or other external factors. This stability not only improves the overall structural strength, but also extends its service life. BRIEF DESCRIPTION OF THE DRAWINGS

The moving ring body 5031 drives the inner tooth groove 5032 to rotate, and the inner tooth groove 5032 engages with the gear 5041 to drive a number of gears 5041 arranged in a ring shape with equal intervals to rotate synchronously. The gear 5041 engages with the rack 5042 so that the several racks 5042 slide synchronously in the slide groove 5021, and the rack 5042 drives the extrusion block A5043 at the outer end to squeeze the extrusion block B602 so that the plug column 601 squeezes the spring 603 into the socket 5012 and the lock hole 403, thereby realizing synchronous locking.

[0065] When the hexagonal wrench is inserted into the rotating block 703 to drive it to rotate, the pulley 706 squeezes the end of the gradient groove 705 with a smaller gap, so that the rotating block 703 can only rotate in one clockwise direction. The other clockwise direction will be locked because the gradient groove 705 squeezes the pulley 706 to achieve a locking effect.

[0066] Then, the first quick connector 301 provided at the top of the Hana structure 2 is plugged into the second quick connector 302 provided on the Uni structure 4. During the plugging, the plug block 3012 is inserted into the slot 3013, and the rotary lock plate 3017 on the rotating groove 3014 of the plug block 3012 rotates. During the insertion process, the two rotary lock plates 3017 squeeze each other, causing the rotating ends of the two rotary lock plates 3017 to rotate in the rotating groove 3014 in a cylindrical shape. After the rotation, the two modules are locked. When it is necessary to split, the other end of the rotary lock plate 3017 is turned so that the rotating end of the rotary lock plate 3017 rotates in the rotating groove 3014 in a cylindrical shape in the opposite direction until the straight end of the semi-cylinder rotates to a vertical state, so that the two plug blocks 3012 can be pulled out of the slot 3013.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
