Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building engineering technology, specifically a novel steel-wood composite roof structure. Background Technology
[0002] In the current construction field, roof structure design faces numerous challenges. Traditional pure steel roof structures, while strong, are heavy and costly, and have shortcomings in insulation and environmental protection. Pure wood roof structures, limited by the strength of wood, have smaller spans and require improved durability. This innovative design scheme for a new steel-wood composite roof structure aims to combine the advantages of steel and wood, overcoming their respective shortcomings. Through rational structural design, it achieves large-span coverage to meet the needs of different architectural spaces. At the same time, it reduces structural weight and material consumption, thereby lowering costs. Furthermore, it improves the roof's insulation performance, enhances structural durability and environmental friendliness, and creates a safe, economical, comfortable, and sustainable building roof system.
[0003] Meanwhile, a detailed design method for a spatial irregular steel-wood composite structure roof, with announcement number CN119004588A, is disclosed. The method includes the following steps: First, based on the design drawings, determine whether an irregular roof exists. Establish a BIM building appearance model for the irregular roof and export its geometric characteristic parameters from the appearance model. Classify the irregular roof according to its geometric characteristics. Next, arrange the steel frame and wood structure, establish a BIM model of the steel-wood composite system, and import the BIM model into structural design software for stress verification. Adjust the component sections based on the software analysis results to ensure overall structural stress balance. After the component sections are adjusted, detailed design is performed on the steel-wood connection nodes and wood-wood connection nodes, and the installation of the steel-wood composite structure is simulated in the software. This method can reasonably reduce material usage, leverage the mechanical and decorative properties of steel and wood, and simultaneously provide a tall and spacious interior space.
[0004] If the above-mentioned spatial irregular steel-wood composite structure roof detailed design method is used to make the wooden structural components the main load-bearing components of the roof truss system, the wooden components will not perform well under tension due to the anisotropic nature of the wood, low tensile strength, and serious loss of joint strength. Moreover, the material properties of wood result in the structural components generally having large cross-sectional dimensions and large self-weight, making construction and installation difficult. Often, a large number of diagonal braces are required to ensure its spatial stability.
[0005] Therefore, a novel steel-wood composite roof structure is proposed to address the above problems. Utility Model Content

[0011] By adopting the above technical solution, the waterproof layer can effectively prevent rainwater and other moisture from penetrating into the roof structure, protect the insulation board and other components from water erosion, and extend the service life of the roof.
[0012] Preferably, a purlin is fitted to the inner side of the U-shaped hoop, and the purlin is fitted to the wooden sheath.
[0013] By adopting the above technical solution, the purlins can be used to increase the lateral support of the roof structure, thereby improving the roof's load-bearing capacity and resistance to deformation.
[0014] Preferably, a roof truss web member is fixedly provided on the lower end face of the wooden sheath, a roof truss lower chord member is fixedly provided on the lower end face of the roof truss web member, and a roof truss upper chord member is fixedly provided on the lower end face of the wooden sheath, and the roof truss upper chord member is fixedly provided with the roof truss web member.

[0016] Preferably, a fixing frame is fixedly provided on the right end face of the wooden plank, and a guide plate is fixedly provided on the lower end face of the fixing frame.
[0017] By adopting the above technical solution, the guide plate can guide rainwater and other water flow in a specific direction, preventing rainwater from accumulating on the roof and reducing the risk of roof leakage.
[0018] Preferably, the right end of the guide plate is provided with a guide port, and the guide port is inside the fixing frame, and a fixing plate is fixedly provided on the lower end face of the guide plate.
[0019] By adopting the above technical solution, rainwater can be discharged more accurately through the backflow outlet, avoiding water splashing everywhere.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. This utility model uses steel pads to increase the contact area between the galvanized rectangular tube and other components, disperse pressure, and improve the stability of the structure. The U-shaped clamps can effectively prevent relative displacement between components, making the entire structure more robust. The nuts make the installation process relatively simple and easy for construction personnel to assemble. Moreover, if a component has a problem during later maintenance, it can be easily disassembled and replaced.
[0022] 2. This utility model uses a connecting layer to serve as a transition and adhesive, enabling the wooden roofing board and insulation board to be better bonded together, thus ensuring the integrity and stability of the roof structure.

A matching nut 10 is attached to the upper end face of the steel pad 9, and the matching nut 10 and the U-shaped hoop 12 are spirally arranged. Through the steel pad 9, the contact area between the galvanized rectangular tube 8 and other components can be increased, the pressure can be distributed, and the stability of the structure can be improved. Through the U-shaped hoop 12, the relative displacement between components can be effectively prevented, making the entire structure more robust. Through the nut, the operation during installation is relatively simple, making it convenient for construction personnel to assemble. Moreover, if a component has a problem during later maintenance, it can be easily disassembled and replaced.
[0031] In this embodiment, a wooden roof board 1 is fixedly installed on the outer side of the U-shaped hoop 12, a connecting layer 2 is fixedly installed on the upper surface of the wooden roof board 1, and an insulation board 3 is fixedly installed on the upper surface of the connecting layer 2. The wooden roof board 1 has a certain insulation performance. On this basis, the insulation board 3 can further enhance the insulation effect of the roof, reduce the loss of indoor heat, reduce energy consumption, and improve indoor comfort.
[0032] A waterproof layer 4 is fixedly provided on the upper surface of the insulation board 3, and the waterproof layer 4 is attached to the steel pad 9. Through the waterproof layer 4, rainwater and other moisture can be effectively prevented from penetrating into the interior of the roof structure, protecting the insulation board 3 and other components from water erosion and extending the service life of the roof.
[0033] The inner side of the U-shaped hoop 12 is fitted with a purlin 11, and the purlin 11 is fitted with the wooden roof board 1. The purlin 11 can increase the lateral support of the roof structure and improve the load-bearing capacity and deformation resistance of the roof.
[0034] The lower end face of the wooden roof board 1 is fixedly provided with a roof truss web member 5, the lower end face of the roof truss web member 5 is fixedly provided with a roof truss lower chord member 6, and the lower end face of the wooden roof board 1 is fixedly provided with a roof truss upper chord member 7.

The lower end face of the guide plate 14 is fixed with a fixing plate 15. Through the guide port, rainwater can be discharged more accurately, avoiding water splashing everywhere.
[0037] The working principle and process of a new type of steel-wood composite roof structure:
[0038] Before construction, materials must be rigorously screened and inspected to ensure that the galvanized rectangular tube 8, steel pad 9, U-shaped hoop 12, matching nut 10, wooden shingle 1, insulation board 3, waterproof layer 4, purlin 11, roof truss web member 5, roof truss lower chord 6, roof truss upper chord 7, fixing frame 13, guide plate 14, and fixing plate 15 meet the quality standards and specifications of the materials. Simultaneously, all necessary installation and measuring tools must be prepared to ensure smooth construction. First, the galvanized rectangular tube 8 is installed, precisely placed and fixed in the predetermined position. Next, the steel pad 9 is installed on its lower end, ensuring a secure connection. Then, the U-shaped hoop 12 is inserted through the steel pad 9, and the matching nut 10 is placed on the upper end of the steel pad 9 and screwed onto the U-shaped hoop 12 to achieve the specified tightness. Simultaneously, the purlin 11 is fitted inside the U-shaped hoop 12, ensuring it connects with the subsequently installed wooden shingle... With the board 1 well-fitted, the wooden roofing board 1 is fixedly installed on the outside of the U-shaped hoop 12 to ensure its flatness and firmness. The roof truss web members 5, the roof truss lower chord members 6, and the roof truss upper chord members 7 are installed sequentially on the lower end face of the wooden roofing board 1 to form a stable roof truss structure. The connection between each member must be tight, and the angle and spacing must be strictly implemented according to the design requirements. The connecting layer 2, the insulation board 3, and the waterproof layer 4 are laid sequentially on the upper end face of the wooden roofing board 1. The connecting layer 2 must be laid evenly, the insulation board 3 must be spliced tightly, and the waterproof layer 4 must be attached to the steel pad 9 to ensure the insulation and waterproof performance of the roof. The fixing frame 13 is installed on the right end face of the wooden roofing board 1, and the guide plate 14 is installed on its lower end face to ensure a certain tilt angle. The fixing plate 15 is installed on the lower end face of the guide plate 14, and the guide port 16 is opened on its right end, with the guide port 16 located inside the fixing frame 13 to ensure that rainwater is discharged smoothly, which plays the role of a new type of steel-wood composite roofing method.
