Description

Technical Field

[0001] This utility model relates to the field of modern agricultural housing construction technology, and in particular to a single-specification light steel keel plug-in fixing structure and a housing steel structure using this fixing structure. Background Technology

[0002] Light steel keel is a new type of building material. With the development of my country's modernization, it is widely used in hotels, airport terminals, bus stations, train stations, amusement parks, shopping malls, factories, office buildings, renovation of old buildings, interior decoration, ceilings, and other places. Light steel keel ceilings are lightweight, high-strength, and adaptable to waterproofing, shock absorption, dustproofing, sound insulation, sound absorption, and temperature control. They also have advantages such as short construction time and simple construction. Therefore, light steel houses are gradually replacing traditional brick-concrete buildings in the low-rise construction field, becoming a new generation of building forms. Due to their short construction time and convenient construction, they are also widely used in modern agriculture.

[0003] Traditional light steel frame house keel structure design involves various methods for connecting the keel joints. Some methods use welding for fastening, but welding is time-consuming and labor-intensive, resulting in high labor costs for welders. Other keel structures use external angle irons or support frames for fastening, which are aesthetically unappealing. Furthermore, to facilitate connections, multiple different specifications of keels are used within the same steel structure, making keel processing difficult. Summary of the Invention

[0004] This utility model provides a single-specification light steel keel plug-in fixing structure and a house steel structure using this fixing structure. It realizes a new connection method with convenient connection, high stability, convenient processing and beautiful structure by using light steel keels of the same specification.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a single-specification light steel keel plug-in fixing structure, including a first beam frame and a second beam frame, wherein the first beam frame and the second beam frame are C-shaped light steel keels of the same specification, including a bottom plate, a side plate and an inner flange;

[0006] The first beam frame has a beam frame channel on its bottom plate, and the second beam frame has a constricted part. The constricted part of the second beam frame is inserted through into the beam frame channel of the first beam frame. The beam frame channel is also provided with a positioning structure that cooperates with the bottom plate of the constricted part.

[0007] The height between the bottom plate and the side plate of the constricted section is less than the length of the beam frame channel. An installation gap is reserved between the constricted section and the beam frame channel. The width between the two side plates of the constricted section corresponds to the width of the beam frame channel. The side plate of the constricted section is fitted and fixedly connected to the side plate of the first beam frame.

[0008] As a preferred technical solution, the beam frame channel includes a channel body, and the front and rear sides of the channel body are provided with outwardly protruding arc-shaped avoidance areas, and the positioning structure is provided on the left and right sides of the arc-shaped avoidance areas.

[0009] As a preferred technical solution, the positioning structure is a positioning plane, and the bottom surface of the constricted portion abuts against the positioning plane.

[0010] As a preferred technical solution, the constricted portion includes a groove recessed on the base plate toward the opening and an inner folded surface on the side plate connected to the base plate.

[0011] As a preferred technical solution, the inner flap is provided with an avoidance cut at the position corresponding to the beam frame passage.

[0012] As a preferred technical solution, the side plates of the first beam frame and the second beam frame are fixedly connected by screws or rivets.

[0013] Another preferred technical solution is a steel structure for a house, including a first beam frame and a second beam frame, wherein the first beam frame and the second beam frame are connected and fixed by a single-specification light steel keel plug-in structure as described above.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] By utilizing the beam frame channel and the constriction section between the beam frames, one beam frame can pass through another beam frame for a fixed connection. This connection method does not require welding or external support structures such as angle steel or support frames. It is not only aesthetically pleasing but also convenient to connect. It can be quickly positioned to achieve a fixed connection. Furthermore, the tight fit between the two beam frames ensures high connection stability.

[0016] This application, through structural design of the beam frame surface, enables the smooth insertion and fixing of light steel keels of the same specification. This allows for the use of only light steel keels of the same specification to meet the needs of steel structure construction. A single production line can process all the light steel keels required for the steel structure, making processing convenient and cost-effective. This method of constructing steel structures using light steel keels of the same specification provides a new method for building steel structure construction, effectively reducing costs and contributing to the development and promotion of the steel structure industry.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0031] Figure 1This is a type of steel structure for housing, assembled from multiple beams. All beams are C-shaped light steel keels of the same specification. In order to achieve the connection between two intersecting beams, this application provides a single-specification light steel keel plug-in fixing structure, which can ensure a quick and stable connection between two beams.

[0032] To distinguish the two beam frames, they are named Beam Frame 10 and Beam Frame 20, respectively. Beam Frame 10 and Beam Frame 20 are both C-shaped light steel keels of the same specification, including a base plate, side plates, and inner flanges. See the structural diagram for details. Figure 2 and Figure 3 This is a commonly used structure in the industry, which is formed by cold bending using a cold bending forming machine.

[0033] A single-specification light steel keel plug-in fixing structure includes a first beam frame 10 and a second beam frame 20. The first beam frame 10 and the second beam frame 20 are assembled and fixed by plugging in. In order to achieve smooth plugging, the surface of the first beam frame 10 and the second beam frame 20 needs to be structurally designed.

[0034] See Figure 4 and Figure 5 The diagram shows the structure of the first beam frame 10. The bottom plate of the first beam frame 10 is provided with a beam frame channel 11. The two ends of the beam frame channel 11 are located on the inner surfaces of the two side plates. The beam frame channel 11 is used for the passage and positioning of the second beam frame 20. The inner flap of the first beam frame 10 is provided with an avoidance cut 12 at a position corresponding to the beam frame channel 11. The avoidance cut 12 is used to avoid the passage of the second beam frame 20 and avoid interference.

[0035] The first beam frame 10 is processed as follows: before the plate is cold-bent, the beam frame channel 11 and avoidance cut 12 are processed on the production line according to the preset position using punching equipment or laser cutting technology. Then, it is cold-bent and formed using cold bending technology, and finally cut to a fixed length. The entire processing process can be completed in one production line.

[0036] See Figure 6The beam frame channel 11 includes a channel body. The channel body has outwardly protruding arc-shaped clearance areas 11a on its front and rear sides. Positioning structures, specifically positioning planes 11b, are provided at both ends of the arc-shaped clearance areas 11a. These positioning structures are used to abut and position the bottom plate of the second beam frame 20, thereby improving strength. In this embodiment, the arc-shaped clearance areas 11a have several functions: first, they reduce the contact area with the bottom plate of the second beam frame 20, ensuring minimal friction between the second beam frame 20 and its bottom plate during installation through the channel body; second, the arc-shaped clearance areas 11a are machined, and the positioning planes 11b naturally form at both ends, facilitating abutment and positioning between the positioning planes 11b and the second beam frame 20; and third, they reduce weight.

[0037] See Figure 7 The second beam frame 20 is provided with a constricted portion 21, which is inserted through into the beam frame channel 11 of the first beam frame 10. The constricted portion 21 is used to connect with the first beam frame 10, and the bottom surface of the constricted portion 21 abuts against the positioning plane 11b to ensure positioning. The height between the bottom plate of the constricted portion 21 and the inner flange is less than the length of the beam frame channel 11. An installation gap is reserved between the constricted portion 21 and the beam frame channel 11 to facilitate the penetration of the non-constricted portion (see...). Figure 11 In the S), the width between the two side plates of the constricted portion 21 corresponds to the width of the beam frame channel 11, and the side plates of the constricted portion 21 are fitted and fixedly connected to the side plates of the first beam frame 10.

[0038] The constricted opening design on the second beam frame 20 is to ensure that the constricted portion 21 can be fully inserted into the beam frame channel 11 of the first beam frame 10, thus ensuring that the first beam frame 10 and the second beam frame 20 can be inserted together. The constricted portion 21 includes a groove 21a recessed towards the opening on the base plate and an inner folded surface 21b on the side plate connected to the base plate.

[0039] The processing method of the second beam 20 is as follows: the plate is cold-bent using cold bending technology to form a shape such as... Figure 3 The traditional C-shaped light steel keel shown is then processed on the production line using a necking technique to create the necked section 21 according to a preset position. Finally, it is cut to a fixed length. The entire processing can be completed in one go on a single production line. See the cross-section before necking. Figure 8 (a) A groove 21a is formed by pressing the bottom plate from bottom to opening using a necking device, while the left and right sides are pressed inward to form an inner folded surface 21b. The cross-section after necking is shown in the figure. Figure 8(b) The height H1 of the bottom plate and the inner flange after the mouth is narrowed is equal to the height H of the bottom plate and the inner flange before the mouth is narrowed, and the width L1 between the two side plates after the mouth is narrowed is less than the width L between the two side plates before the mouth is narrowed.

[0040] The side plates of the first beam frame 10 and the second beam frame 20 are fixedly connected by screws or rivets. They can be directly connected by rivets, or mounting holes can be pre-set at corresponding positions of the first beam frame 10 and the second beam frame 20, and then screws can be used to fix them at the mounting hole positions.

[0041] The installation method of the first beam frame 10 and the second beam frame 20 is as follows:

[0042] Before installation, the second beam frame 20 passes through the beam frame channel 11 of the first beam frame 10, and the position of the second beam frame 20 is moved so that the position of the constricted part 21 of the second beam frame 20 corresponds to the beam frame channel 11 of the first beam frame 10. Then, the side plates of the two beam frames are fixed with rivets.

[0043] When the constricted portion 21 of the second beam frame 20 has not moved to the beam frame channel 11 of the first beam frame 10, since the two beam frames are of the same specification profile, the width of the side plate of the first beam frame 10 is equal to the width of the side plate of the second beam frame 20. Therefore, the two side plates of the second beam frame 20 will press against the two side plates of the first beam frame 10 to both sides. See the description below. Figure 10 At this time, the reserved installation gap comes into play, and the two side plates of the second beam frame 20 will be forced to deform to accommodate the insertion of the first beam frame 10 as a whole. When the second beam frame 20 moves along the beam frame channel 11, the friction of the bottom plate of the second beam frame 20 is reduced due to the setting of the arc-shaped avoidance area 11a.

[0044] When the constricted portion 21 moves to the beam frame channel 11, the side plate of the first beam frame 10 recovers its deformation and comes into close contact with the outer end face of the side plate of the constricted portion 21. At the same time, the two ends of the bottom plate of the constricted portion 21 abut against the positioning plane 11b. An installation gap S will appear between the inner flange of the constricted portion 21 and the other positioning plane 11b. See the attached diagram for details. Figure 11 Then, the side plates of the two beams can be fixed with rivets. Since the side plates are in close contact with each other and the bottom plate of the constricted part 21 is in contact with the positioning plane 11b, the multi-point contact can ensure the connection strength at the joint.

[0045] The first beam frame 10 and the second beam frame 20 can be processed separately on the same production line according to different processing requirements. The processing method is simple and the equipment cost is low.

[0046] See Figure 1A steel structure for a building includes a first beam frame 10 and a second beam frame 20. The first beam frame 10 and the second beam frame 20 are connected and fixed by a single-specification light steel keel insertion and fixing structure as described above. See [link to relevant documentation]. Figure 1 At point A in the middle. Regarding the steel structure of this building, for other details... Figure 1 At point B, where a through connection is not required, there is no need to process the beam frame channel. Only a constriction design is needed at the end of one beam frame, and an avoidance cut design is needed at the position of the other beam frame. When connecting, the constricted part is inserted into the corresponding position and fixed with rivets, making the processing method simpler.

[0047] Before processing, the user inputs the required dimensions, shape, and other specifications of the house into the production line controller. The controller then calculates and builds a model within the system using light steel keel to meet the strength requirements. After the user confirms that everything is correct, the controller disassembles the model into several light steel keels. Each light steel keel is then processed by the production line according to the requirements. Once all the light steel keels are processed, the user can assemble the house according to the markings on the keels. By using the same production line to process different light steel keels, the steel structure of the house can be constructed.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
