Description

Technical Field

[0001] The utility model relates to the technical field of metal eaves rafters, and more particularly to assembled metal eaves rafters. Background Art

[0002] Metal eaves rafters refer to rafters made of metal materials located at the eaves of the building structure. The eaves rafters are the outermost part of the roof base, which supports the roof tiles and transfers the roof load to the roof trusses. In traditional buildings, rafters are usually made of wood, while metal eaves rafters are made of metal materials and have some unique advantages, such as: high strength: able to withstand large loads and have good structural stability, good durability: not easy to decay or be eaten by insects, and have stronger adaptability to the environment, good fire resistance: less likely to burn than wood in the event of a fire, flexible modeling: various complex shapes and styles can be produced through modern processing technology to meet the diverse needs of architectural design. Metal eaves rafters are often used in some modern buildings, industrial buildings or places with special requirements for building performance.

[0003] Chinese patent publication number: CN220285197U, provides a wooden antique eaves structure. This solution overcomes the original technical path of expressing the Ming and Qing styles through the wooden antique eaves structure. The concrete structure in this solution only plays a structural bearing role, and concrete is not used to imitate the traditional casting style. This part of the traditional style is still left to traditional wood work. By designing specific connectors, the traditional style wooden part is tightly and secretly connected to the reinforced concrete structure, achieving an authentic Ming and Qing style eaves in appearance, providing a real and reliable expression of the Ming and Qing architectural style. Concrete construction is still the conventional practice in construction, and the civil engineering cost has not increased too much. The construction of the eaves is completed by a traditional wood construction team. The style is mature, the materials are conventional, and the cost is controllable. However, compared with the wooden antique eaves structure, the metal structure still has considerable advantages. High strength: it can withstand large loads and has good structural stability. Good durability: it is not easy to decay or be eaten by insects, and has stronger adaptability to the environment. Good fire resistance: compared with wood, it is less likely to burn in the event of a fire. Flexible shape: various complex shapes and styles can be produced through modern processing technology to meet the diverse needs of architectural design. Metal eaves rafters are often used in some modern buildings, industrial buildings or places with special requirements for building performance.

[0004] Therefore, in order to solve the above problems, an assembled metal eaves rafter is proposed. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an assembled metal eaves rafter, aiming to solve the problems in the prior art such as inconvenient disassembly, increased transportation costs, and inconvenient splicing during installation on the roof.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0011] In this solution, the rafters are connected to the first metal square tube by bolts to bear and transfer the load. The second metal square tube is fixed in the middle of the rafter to enhance the structural strength and stability of the rafter. It is also inclined and consistent with the inclination angle of the overall structure to ensure uniform force. The top beam is connected to the second metal square tube by bolts to further enhance the stability and bearing capacity of the overall structure.

[0012] Reference Figure 1 - Figure 3 As shown, the plurality of first metal square tubes are all arranged at an angle.

[0013] Reference Figure 1 - Figure 3 As shown, the rafters and the plurality of second metal square tubes are all arranged at an inclination, and the inclination angles of the rafters and the plurality of second metal square tubes are consistent with the inclination angle of the first metal square tubes.

[0015] Reference Figure 1 - Figure 3 As shown, a threaded hole for mounting the top beam is provided at the upper end of the second metal square tube.

[0016] In summary, the present invention has the following beneficial effects:

[0017] This solution has detachable parts such as the crossbeam, the first metal square tube, and the bolts, which can be disassembled during transportation to reduce transportation costs. At the same time, when installed on the roof, they can be directly spliced on the roof for easy installation. At the same time, combined with the connection method with the top beam bolts, the overall stability can be enhanced and the overall structure is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The top mounting assembly 1 includes a crossbeam 101 , a plurality of first metal square tubes 102 are provided in the middle of the crossbeam 101 , and the plurality of first metal square tubes 102 are fixedly connected by bolts 103 ;

[0026] This solution uses the crossbeam 101 to provide an installation base for the first metal square tube 102 to support the entire top structure. The first metal square tube 102 is set at an angle to enhance the stability and bearing capacity of the structure. It is fixed to the crossbeam 101 by bolts 103 to facilitate installation and disassembly while ensuring the stability of the connection.

[0033] Specific implementation process: First, transport the top mounting assembly 1 and the connecting mounting assembly 2 to the installation site. Since the crossbeam 101, first metal square tube 102, rafter 201, second metal square tube 202, and top beam 203 components are removable before transportation, transportation difficulty and cost are greatly reduced. Upon arrival at the site, installation begins. Multiple inclined first metal square tubes 102 are secured to the center of the crossbeam 101 using bolts 103. Then, the rafter 201 is secured to the upper end of the first metal square tube 102 using bolts 103. Next, a plurality of second metal square tubes 202 of the same inclined arrangement are fixed in the middle of the rafter 201, and finally the top beam 203 is fixed to the upper end of the second metal square tube 202 by means of bolts 103. This assembled structural design enables the various components to be quickly spliced and installed on site, facilitating construction. At the same time, the stability of the structure is ensured by means of bolt connection, which can effectively support the roof tiles and transfer the roof load to the roof truss. It is convenient to transport: the various components are detachable, which can save space during transportation, reduce transportation costs and difficulty, and is easy to install: they can be directly spliced and installed on site on the roof, reducing the complexity and time cost of construction, and the structure is stable: the various components are connected by bolts to ensure the stability of the overall structure when bearing loads, and cost savings: the detachable design reduces transportation costs, and rapid on-site installation can also save labor costs, and high flexibility: the various components can be flexibly combined and adjusted according to actual needs.
