Description

Technical Field

[0001] This invention relates to the field of structural design technology for steel structure industrial buildings, and in particular to an integrated connection node mechanism and assembly method for beam-column-roof trusses in light steel factory buildings. Background Technology

[0002] Currently, the connections between steel columns and beams, and roof trusses in steel structure industrial buildings mostly employ traditional welding and external bolted connection plates. This existing technology has several drawbacks: (1) Low assembly efficiency: A large number of alignment, welding and drilling operations are required on site, which requires high technical skills from construction personnel and has poor controllability of the construction period.

[0003] (2) Poor connection accuracy: Traditional external connection plate connection is prone to misalignment, and the flatness and verticality of the overall frame are difficult to guarantee.

[0004] (3) Weak structural integrity: The beam-column and column-roof truss connection nodes are split connections, and the nodes have limited shear resistance, bending resistance and overturning resistance performance, resulting in insufficient overall seismic and load stability of the factory building.

[0005] (4) Inconvenient maintenance: Welded nodes cannot be disassembled, bolted nodes have no positioning and limiting structure, and long-term loads can easily lead to problems such as loose bolts and node deformation, resulting in high maintenance and replacement costs.

[0006] Therefore, there is an urgent need for a steel structure factory beam-column-roof truss connection structure that can be quickly aligned, embedded in assembly, with integrated locking of multiple components, and with strong structural stability. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated connection node mechanism and assembly method for beams, columns and roof trusses in light steel factory buildings, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides an integrated connection node mechanism for beams, columns, and roof trusses of a light steel factory building, including a steel column, a crossbeam provided on the upper part of the steel column, a roof truss beam provided on one side of the crossbeam and the steel column, and the roof truss beam, the crossbeam, and the steel column are connected by a connecting component. The steel column, the roof truss beam, and the connecting assembly are fixed together by a first fastening assembly; The crossbeam and the connecting assembly are secured together by a second fastening assembly.

[0009] Preferably, the steel column is provided with reinforcing ribs on both sides.

[0010] Preferably, the bottom of the crossbeam is provided with a horizontal slide rail.

[0011] Preferably, the connecting assembly includes a transition member, an assembly cavity is provided above the transition member, and the crossbeam is disposed within the assembly cavity; The bottom of the assembly cavity is provided with a horizontal sliding groove, which is adapted to the horizontal slide rail.

[0012] Preferably, a connection opening is provided below the adapter component, and one end of the steel column is disposed in the connection opening.

[0013] Preferably, the front side of the adapter component is provided with a horizontal support groove.

[0014] Preferably, one end of the roof truss beam is provided with a connecting part, which is disposed within the horizontal bracket.

[0015] Preferably, the first fastening assembly includes two angular supports, one end of which is passed through by a fastener, which secures the angular supports, the transition member, and the roof truss beam. The other end of the two angular supports is passed through by a second fastener, which secures the angular support to the steel column.

[0016] Preferably, the second fastening assembly includes two angle steels symmetrically arranged on both sides of the adapter component. One end of the angle steel is connected to the horizontal slide rail via fastener three, and the other end of the angle steel is connected to the adapter component via fastener four.

[0017] An assembly method for an integrated connection node mechanism for beams, columns, and roof trusses in a light steel factory building includes the following steps: S1. Steel column and connecting component assembly: Align the connecting opening of the transition component with the top of the steel column, and fit and wrap the top of the steel column from top to bottom. Rely on the shape of the steel column to achieve precise positioning and initial fixation of the connecting component, so that the stiffening rib fits the inner wall of the connecting opening, improving the fitting degree and stress performance. S2. Embedded assembly of crossbeam and connecting component: Align the horizontal slide rail at the bottom of the crossbeam with the horizontal slide groove of the assembly, and push the crossbeam horizontally into the assembly cavity. Through the cooperation of the horizontal slide groove and the horizontal slide rail, the crossbeam is aligned and embedded. After the crossbeam is fully inserted into the assembly cavity, the crossbeam and the outer side of the transition component are connected by two angle steels. Fasteners three and four are used for through locking to achieve rigid fixation of the crossbeam and the connecting component. S3. Roof truss beam assembly and overall reinforcement: Align the connecting part at the end of the roof truss beam with the horizontal bracket and insert it to complete the positioning and support of the roof truss beam. Then, install two angled supports diagonally between the outside of the steel column, the bottom of the connecting component and the lower side of the roof truss beam to form a triangular support system. Finally, lock the upper and lower connecting ends of the angled supports with fastener one and fastener two respectively to connect the steel column, connecting component and roof truss beam into a stable whole structure.

[0018] Therefore, the present invention, employing the above-mentioned integrated connection node mechanism and assembly method for beam-column roof trusses in light steel factory buildings, has the following beneficial effects: (1) Extremely high assembly efficiency: This mechanism adopts a modular assembly design with socket and groove embedded, which eliminates the need for precise on-site alignment and large-area welding. Assembly can be completed by simply tightening high-strength bolts, which greatly shortens the construction period of the factory and meets the construction needs of prefabricated buildings.

[0019] (2) High installation accuracy and good sealing: This mechanism relies on the structural cooperation of horizontal slides, horizontal slide rails, wrap-around connection openings and horizontal brackets to achieve full structural mechanical limit, completely avoid the problem of component installation offset and misalignment, and ensure the overall flatness of the factory frame.

[0020] (3) Strong structural integrity and load-bearing capacity: This structure achieves the three-in-one connection of steel columns, beams and roof trusses through integrated connection components. With the addition of stiffening ribs, angle steel reinforcement and triangular support structure, the shear resistance, bending resistance and overturning resistance of the nodes are greatly improved, and the overall seismic resistance and load resistance of the factory building are significantly improved.

[0021] (4) Easy disassembly and maintenance: The entire structure of this device is connected by high-strength bolts, eliminating the need for permanent welding. This makes it extremely convenient to inspect, replace, and modify components later, reducing the cost of plant operation and maintenance.

[0022] (5) Lightweight structure and reasonable stress: The cross section of the beam and the variable cross section (box type and I type) of the roof truss beam of this structure reduce the overall self-weight while ensuring the structural strength, making it suitable for use in large-span industrial plants.

[0027] Example Please see Figures 1-6 This invention provides an integrated connection node mechanism for beams, columns, and roof trusses in a light steel factory building. It includes a steel column 1, a crossbeam 2 mounted on the upper part of the steel column 1, and a roof truss beam 3 mounted on one side of the crossbeam 2 and the steel column 1. The roof truss beam 3, the crossbeam 2, and the steel column 1 are connected by a connecting component. The steel column 1, the roof truss beam 3, and the connecting component are fixed together by a first fastening component 5. The crossbeam 2 and the connecting component are fixed together by a second fastening component 6.

[0028] In this example, steel column 1 adopts an I-beam cross-section structure and serves as the main vertical load-bearing component. Stiffening ribs 11 are welded to both sides of the top end face of steel column 1. These stiffening ribs 11 are vertically fixed to the web and flanges of steel column 1, effectively strengthening the local compressive and shear resistance of the top of steel column 1, preventing end deformation under pressure, and increasing the upper limit of the joint's load-bearing capacity.

[0029] In this embodiment, the crossbeam 2 adopts an upward-opening channel steel section as a transverse load-bearing connecting beam for the factory building. The bottom of the crossbeam 2 is integrally formed or welded to a horizontal slide rail 21. The size and spacing of the horizontal slide rail 21 are precisely matched with the horizontal slide groove 43, which can realize sliding embedded assembly.

[0030] In this embodiment, the roof truss beam 3 is the load-bearing structure of the factory roof. Both ends of the roof truss beam 3 are special variable cross-section composite structures: the connecting part 31 of the roof truss beam 3 has a box-section structure to ensure end-bearing rigidity; the sloping upward section of the roof truss beam 3 extending from the connecting part 31 to the main body has an I-section structure, balancing overall lightweight and bending resistance. The box-section of the connecting part 31 can be precisely inserted into the horizontal bracket 45 on the front side of the connecting component, achieving limiting and fixing.

[0031] The connecting component in this embodiment is an integral cast steel or steel plate welded structure, including a transition component 41. An assembly cavity 42 is provided above the transition component 41, and the crossbeam 2 is disposed in the assembly cavity 42. A horizontal slide groove 43 with limiting and guiding function is provided at the bottom of the assembly cavity 42, and the horizontal slide groove 43 is adapted to the horizontal slide rail 21.

[0032] A connecting opening 44 is provided below the adapter component 41, and one end of the steel column 1 is placed inside the connecting opening 44. The size of the connecting opening 44 matches the shape of the top of the I-beam steel column 1, and can completely fit and wrap the top of the steel column 1, realizing the initial positioning and fitting of the connecting component and the steel column 1.

[0033] The front side of the transition component 41 is provided with a concave horizontal bracket 45, and the connecting part 31 of the roof truss beam 3 is set in the horizontal bracket 45. The horizontal bracket 45 is used to support and limit the end of the roof truss beam 3, so as to achieve precise positioning and installation of the roof truss beam 3.

[0034] The first fastening assembly 5 includes two angle supports 51. One end of each angle support 51 is passed through by a fastener 52, which secures the angle support 51, the transition member 41, and the roof truss beam 3. The other end of each angle support 51 is passed through by a fastener 53, which secures the angle support 51 and the steel column 1.

[0035] The second fastening assembly 6 includes two angle steels 61 symmetrically arranged on both sides of the adapter 41. One end of the angle steel 61 is connected to the horizontal slide rail 21 through fastener three 62, and the other end of the angle steel 61 is connected to the adapter 41 through fastener four 63.

[0036] In this embodiment, fastener 1 52, fastener 2 53, fastener 3 62 and fastener 4 63 are all high-strength bolts and high-strength nuts.

[0037] An assembly method for an integrated connection node mechanism for beams, columns, and roof trusses in a light steel factory building includes the following steps: S1. Assembly of steel column 1 and connecting components: Align the connecting opening 44 of the adapter component 41 with the top of the steel column 1, and wrap it around the top of the steel column 1 from top to bottom. The connecting components are precisely positioned and initially fixed by relying on the shape of the steel column 1, so that the reinforcing rib 11 fits the inner wall of the connecting opening 44, thereby improving the fitting degree and stress performance.

[0038] S2. Embedded Assembly of Crossbeam 2 and Connecting Component: Align the horizontal slide rail 21 at the bottom of crossbeam 2 with the horizontal slide groove 43 of the assembly, and push crossbeam 2 horizontally into the assembly cavity 42. Through the cooperation of the horizontal slide groove 43 and the horizontal slide rail 21, the crossbeam 2 is aligned without gaps and embeddedly installed, completely solving the problem of misalignment of the traditional crossbeam 2. After crossbeam 2 is fully inserted into the assembly cavity 42, the outer surfaces of crossbeam 2 and transition component 41 are connected by two angle steels 61, and fasteners three 62 and four 63 are used for through-locking to achieve rigid fixation of crossbeam 2 and connecting component.

[0039] S3. Assembly and overall reinforcement of roof truss beam 3: Align the connecting part 31 at the end of the roof truss beam 3 with the horizontal bracket 45 and insert it to complete the positioning and support of the roof truss beam 3. Then, install two angled supports 51 obliquely on the outside of the steel column 1, between the bottom of the connecting component and the lower side of the roof truss beam 3 to form a triangular support system. Finally, lock the upper and lower connecting ends of the angled supports 51 with fastener 1 52 and fastener 2 53 respectively to connect the steel column 1, the connecting component and the roof truss beam 3 into a stable overall structure.

[0040] Therefore, the present invention adopts the above-mentioned integrated connection node mechanism and assembly method for beam-column roof trusses of light steel factory buildings, which is suitable for the main frame construction of large-span, prefabricated steel structure industrial buildings, and has the characteristics of high assembly efficiency, strong structural integrity, good seismic stability and high installation accuracy.
