Description

Technical Field

[0001] This utility model belongs to the field of prefabricated housing technology, and in particular relates to a prefabricated housing frame structure. Background Technology

[0002] Prefabricated housing is a type of building that uses industrialized prefabricated components for rapid assembly on the construction site. Its core features are standardized design, factory production, and modular construction, which greatly improves construction efficiency and reduces resource waste. Major structural components (such as wall panels, floor slabs, beams, and columns) are prefabricated in the factory and then assembled on the construction site using processes such as bolting, welding, or grouting sleeves. The main structure can be completed within a few days. This type of building has advantages such as lightweight, energy saving and environmental protection, and disassembly and reuse. At the same time, combined with BIM technology, it can accurately control quality and is suitable for residential, temporary facilities, and post-disaster emergency buildings. Current technology has developed into various types such as steel structure, concrete, wood structure, and hybrid systems, which is in line with the development trend of intelligent and green construction industry.

[0003] Currently, prefabricated houses are widely used due to their short construction cycle and high degree of structural standardization. However, existing prefabricated houses still have some technical problems in actual construction. For example, the connecting parts in the house frame usually use fixed bolts or welding, which lacks flexibility. This makes it inconvenient to operate and maintain during the installation and replacement of reinforcement bars, resulting in low maintenance efficiency and affecting the overall assembly efficiency and later maintainability. In addition, when facing external forces such as earthquakes, the seismic-resistant structure of existing house frames mostly uses rigid connections or simple supports, lacking effective energy dissipation devices, resulting in limited shock absorption and certain safety hazards.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a prefabricated house frame structure, such as... Figure 1-4 As shown, it includes: a base frame 1, a support frame 2 fixedly connected to the base frame 1, a top frame 3 installed on the support frame 2, several fixing devices 4 fixedly connected inside the base frame 1 and the support frame 2, and an anti-seismic device 5 fixedly connected to the base frame 1.

[0024] The fixing device 4 includes a fixing seat 401, which is fixedly connected to the bottom frame 1. A positioning groove 402 is provided in the fixing seat 401, and a positioning rod 403 is locked in the positioning groove 402. A long groove 404 is provided in the positioning rod 403, and a reinforcing rod 405 is provided in the long groove 404. The reinforcing rod 405 is locked on the lower surface of the support frame 2.

[0025] In a further preferred embodiment of this utility model, the fixing device 4 further includes a limiting rod 407, which is engaged in the positioning rod 403. The reinforcing rod 405 has a plurality of limiting holes 406, and the limiting rod 407 is engaged in one of the limiting holes 406. The internal dimension of the long groove 404 is slightly larger than the cross-sectional dimension of the reinforcing rod 405, and a sliding connection is formed between the reinforcing rod 405 and the long groove 404. The limiting rod 407 has an external thread, and the limiting hole 406 has an internal thread, and the two form a threaded connection.

[0026] In this embodiment, the positioning rod 403 is inserted into the positioning groove 402 of the fixed base 401, and the long groove 404 is opened longitudinally along the positioning rod 403, so that the reinforcing rod 405 can be slidably positioned in the long groove 404. The fit is precise, which not only facilitates the insertion of the reinforcing rod 405, but also allows the reinforcing rod 405 to be finely adjusted back and forth during installation, improving the connection flexibility and installation accuracy. The cross-section of the reinforcing rod 405 is slightly smaller than the inner diameter of the long groove 404, forming a sliding connection fit, which effectively avoids the problem of rigid jamming, while ensuring smooth operation and adjustable position during installation or disassembly, enhancing the adaptability of on-site construction.

[0027] In a further preferred embodiment of this utility model, the seismic damping device 5 includes a connecting frame 501, which is fixedly connected to the bottom frame 1. A rotating shaft 502 is disposed through the connecting frame 501, and a seismic damper 503 is disposed on the outer sleeve of the rotating shaft 502. A connecting shaft 504 is disposed through one end of the seismic damper 503, and a mounting plate 505 is disposed on the outer sleeve of the connecting shaft 504. The mounting plate 505 is fixedly connected to the support frame 2. The seismic damper 503 is set at a 30-degree tilt angle.

[0028] In this embodiment, the connecting shaft 504 passes through the seismic damper 503 and forms a rotatable fit with it, so that the damper can change its posture according to the direction of the external force when subjected to force, ensuring a flexible response during the energy dissipation process and improving the vibration reduction efficiency; the seismic damper 503 is sleeved on the rotating shaft 502 and can move synchronously with the swing of the rotating shaft 502, realizing the response displacement of the damper in different angle ranges, and improving the adaptability and sensitivity of the seismic device 5 under multi-directional vibration.

[0029] In summary, by setting up a fixing device 4 consisting of a fixed base 401, a positioning groove 402, a positioning rod 403, a reinforcing rod 405, and a limiting rod 407, an adjustable and sliding connection structure is formed. This allows the reinforcing rod 405 to be quickly inserted and positioned on the lower surface of the support frame 2. Combined with the cooperation between the limiting rod 407 and the limiting hole 406, multiple fixing positions can be achieved, facilitating adjustment and positioning during construction. At the same time, this structure has good disassembly. By setting up an anti-seismic device 5 with a rotating shaft 502, a connecting shaft 504, and an anti-seismic damper 503 between the bottom frame 1 and the support frame 2, the damper is arranged at a certain angle. When subjected to lateral impact forces such as earthquakes, it can dissipate energy through rotational connection and in conjunction with the damping components, effectively buffering the damage caused by external forces to the structure.
