Technical Field
[0001] This utility model relates to the field of building construction technology, and more specifically, to a modular building structure frame. Background Technology
[0002] With the continued growth in demand for outdoor vacations, non-permanent vacation homes are gradually becoming the mainstream choice in the market because they comply with regulations prohibiting permanent buildings. Traditional vacation homes mostly adopt an integrated structural design, which has many problems such as poor transportation adaptability, high hoisting difficulty, and low on-site installation efficiency, which seriously restricts their promotion and application.
[0003] In the transportation process, the large size of the integrated holiday home generally exceeds the size and weight limits of conventional road freight, requiring special transportation permits and facing traffic restrictions on some road sections. This not only increases transportation costs but also extends the project turnaround time. During long-distance transportation, the overall structure lacks effective protection, making it prone to component damage and further increasing the loss rate.
[0004] During the hoisting and installation phase, prefabricated holiday homes rely on large hoisting equipment, which is expensive to rent. Furthermore, the equipment has stringent requirements regarding the site's load-bearing capacity and working space, making it difficult to operate in complex terrain. On-site installation involves multiple steps and is significantly affected by weather and human skill levels; errors in the connection between these steps can easily lead to rework. In terms of structural performance, traditional holiday home frames struggle to balance lightweighting and structural strength. Some modular frames have simple roof structure designs, resulting in insufficient resistance to wind loads and rain and snow. The connection between the bottom frame and the upper structure is not tight enough, which can lead to loosening over time and affect overall safety. Therefore, there is an urgent need for a modular housing structure frame that is structurally sound, highly detachable, easy to transport, and highly stable. Utility Model Content

The components of each frame unit are manufactured in a factory using lightweight steel materials, modeled and refined using BIM technology, and then processed on an assembly line. Lightweight steel materials combine lightweight and high strength, reducing overall weight while ensuring structural stability, facilitating transportation and hoisting. After the components are processed, they undergo rust prevention treatment and surface coating. Simultaneously, some basic accessories, such as bolt connections and reserved pipe interfaces, are pre-installed to ensure compatibility with on-site assembly. During assembly, a precast concrete foundation is first laid according to the terrain conditions of the construction site.

The second main frame is tightly connected; wall frames 7 are installed on both sides of the second main frame and at the end furthest from the first main frame, and a load-bearing frame 33 is installed on the inner side of the second main frame to enhance the load-bearing capacity of the second bottom frame unit 3 and provide support for the subsequent installation of the second-floor frame unit 4; a partition frame 8 is set inside the second main frame to divide its inner side into a space area for installing stairs, which facilitates the subsequent assembly of stairs; after the second main frame is installed, the fixing frame 41 is detachably connected to the second top wall frame 32 by bolts to ensure that the fixing frame 41 and the second top wall frame 32 fit tightly.Four third columns 42 are taken, and their lower ends are detachably connected to the four corners of the fixed frame 41, and their upper ends are detachably connected to the four corners of the third top wall frame 43, forming the third main frame.

The first irregularly shaped frame 51, with a wave-like structure, is then installed on the two first connecting frames 52. This wave-like design enhances the roof's drainage performance and wind resistance. For the second roof frame unit 6, the two second connecting frames 62 are detachably bolted to the top of the third roof wall frame 43. Then, the second irregularly shaped frame 61, with its wave-like structure, is installed on the two second connecting frames 62, completing the roof structure assembly. After each frame unit is assembled, all connection nodes are inspected and reinforced to ensure the bolts are securely tightened. Subsequently, pipeline splicing and gap sealing are performed. Pipelines are quickly connected through the interfaces reserved in each frame unit, and gaps are filled with waterproof sealant to ensure the building's waterproof and thermal insulation performance.

Each frame unit adopts a standardized design, strictly adheres to road transport limits, and can be prefabricated in the factory. During transportation, it can be disassembled into independent modules and transported conveniently via flatbed trailers, effectively reducing transportation costs and losses.
