Description

Technical Field

[0001] This application belongs to the field of building assembly technology, and more specifically, it relates to a modular steel structure box house assembly fixing device and box house. Background Technology

[0002] Steel structure box houses are widely used in temporary buildings, emergency housing, modular buildings and other fields, and need to be stacked and combined to improve space utilization.

[0003] Existing modular steel structure container house stacking and fixing technologies mostly suffer from drawbacks such as cumbersome operation, low efficiency, poor safety, and limited applicability. Especially under external forces such as wind loads and earthquakes, they are prone to displacement or overturning. Traditional fixing methods (such as welding and bolt connections) suffer from low disassembly and assembly efficiency and non-reusability. High-strength bolt connections require tightening each bolt individually, a cumbersome process with strict requirements on bolt tightening torque, necessitating individual testing, which undoubtedly increases construction time and labor costs. Welding connections require pre-welding preparation, such as cleaning the welding area and adjusting welding equipment. During welding, strict control of welding parameters is also necessary to ensure weld quality, making the entire welding process time-consuming and similarly detrimental to improving construction efficiency.

[0004] In the process of stacking and assembling modular steel structure container houses, there is a lack of a self-locking device that can quickly and automatically achieve reliable locking, is easy to disassemble, and is applicable to various usage scenarios. Therefore, developing a new type of self-locking device for stacking and assembling modular steel structure container houses has significant practical importance and market demand. Utility Model Content

[0005] To address one of the shortcomings of the existing technology, the purpose of this application is to provide a modular steel structure box house assembly and fixing device, which has the advantages of rapid assembly, automatic locking, convenient disassembly and applicability to various usage scenarios.

[0011] In one embodiment, after the rotating connector is installed on the upper surface of the upper crossbeam, the opening angle range of the rotating connector is 0-45°.

[0012] In one embodiment, the rotating connector is a hinge.

[0013] In one embodiment, the barb plate includes a pressure plate and an adjusting plate, the connection between the pressure plate and the adjusting plate is rotatably mounted on the mounting frame via a rotating shaft, and the angle adjusting member is disposed on the adjusting plate.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0028] like Figures 1-3 As shown, a modular steel structure box house assembly fixing device provided in this application embodiment will now be described. This modular steel structure box house assembly fixing device is installed between an upper box house and a lower box house. Multiple fixing devices securely stack the upper and lower box houses together. Both the upper and lower box houses are modular steel structure box houses, with steel crossbeams at their top and bottom. The fixing device includes a load-bearing component 1, a rotating connector 2, a mounting frame 3, a hook plate 4, and an angle adjusting component 5. In this embodiment, the rotating connector 2 is a hinge with two blades. One blade connects to the load-bearing component 1, and the other blade connects to the upper crossbeam of the lower box house, specifically fixed to the upper surface of the upper crossbeam. The rotating connector 2 can be fixedly connected to the upper surface of the upper crossbeam by welding or screws. The rotating connector 2 is connected to the load-bearing component 1 by screws or welding; under the premise of ensuring structural strength, screws are preferred. If the fixing device does not need to be disassembled later, the rotating connector 2 can be connected to the upper crossbeam and the load-bearing component 1 by first screwing and then welding.

[0029] The support member 1 can be rotatably mounted on the upper surface of the upper crossbeam of the lower housing via the rotating connector 2, thus enabling the mounting frame 3 to be rotated. The mounting frame 3 is mounted on the support member 1 and located on the side of the upper housing. The hook plate 4 is rotatably mounted on the mounting frame 3. When the upper housing is placed on the lower housing, the hook plate 4 can press against the upper surface of the lower crossbeam of the upper housing. To ensure that the hook plate 4 is locked to the lower crossbeam, an angle adjustment member 5 is mounted on the hook plate 4 and used to adjust the rotation angle of the hook plate 4 so that the hook plate 4 presses against the upper surface of the lower crossbeam of the upper housing.

[0030] The installation process is as follows: Figure 2As shown, first, the fixing device is fixed to the upper surface of the upper crossbeam of the lower box-shaped room by rotating connector 2. Then, rotating connector 2 is opened so that the bearing member 1 is at a certain angle to the horizontal plane, ensuring that the hook plate 4 is located on the outside of the lower box-shaped room in the vertical plane, without affecting the vertical lowering and stacking of the upper box-shaped room on the lower box-shaped room. The upper box-shaped room is vertically lowered using the hoisting device. After contacting the bearing plate, its gravity presses the bearing plate down, rotating connector 2 gradually closes, and the hook plate 4 gradually rotates to above the upper surface of the lower crossbeam. After the upper box-shaped room is placed in place, the angle adjustment member 5 is used to rotate the hook plate 4 and make it press against the upper surface of the lower crossbeam for locking. For example, Figure 3 As shown, the upper and lower box-shaped rooms can be stacked face-to-face or staggered by a certain length.

[0031] Preferably, the rotating connector 2 is a high-strength rotating connector 2, and the bearing 1 is an L-shaped corner piece made of high-strength steel. The horizontal plate of the L-shaped corner piece is connected to the rotating connector 2, and the vertical plate of the L-shaped corner piece is connected to the mounting frame 3. The vertical plate is welded to the mounting frame 3; or, the bearing 1 and the mounting frame 3 are integrally formed.

[0032] Preferably, the mounting bracket 3 includes two parallel side plates, the tops of which are used for rotatably mounting the barbed plate 4. The side plates are triangular. The thickness of the side plates is ≥8mm, and they can withstand lateral stresses exceeding 20KN.

[0033] In this embodiment, in order to ensure the stability of the bearing 1 after it is installed on the upper crossbeam and rotated open to a certain angle, the lower end of the mounting bracket 3 is located on the outside of the lower box chamber, that is, the lower end of the side plate is lower than the height of the upper crossbeam. When the rotating connector 2 is opened, the lower end of the mounting bracket 3 abuts against the outer wall of the lower box chamber to limit the opening angle of the rotating connector 2.

[0034] Specifically, after the rotating connector 2 is installed on the upper surface of the upper crossbeam, the mounting bracket 3 allows the opening angle of the rotating connector 2 to be within the range of 0-45°. Preferably, the opening angle of the rotating connector 2 is within the range of 0-30°, that is, when the opening angle of the rotating connector 2 is 30°, the lower end of the mounting bracket 3 abuts against the outer wall of the lower housing, and the horizontal plate of the bearing member 1 forms a 30° angle with the upper surface of the upper crossbeam. At this time, the hook plate 4 is located outside the vertical plane formed by the outer side of the lower housing, so that the upper housing can be lowered. When the opening angle of the rotating connector 2 is 0°, the upper housing has been stacked on the lower housing. Each time, the hook plate 4 rotates and presses against the upper surface of the lower crossbeam to complete self-locking.

[0035] In this embodiment, the barbed plate 4 includes a pressure plate and an adjusting plate, which are integrally formed. The connection between the pressure plate and the adjusting plate is rotatably mounted on the mounting frame 3 via a rotating shaft. The angle adjusting component 5 is mounted on the adjusting plate. Specifically, the barbed plate 4 is an L-shaped plate. The angle adjusting component 5 is a high-strength screw, which is threadedly connected to the adjusting plate and used to abut against the outer side of the upper housing. Tightening the high-strength screw causes the adjusting plate to rotate upward, thereby causing the pressure plate to rotate downward to press and lock the lower crossbeam. The high-strength screw is an M12 high-strength screw.

[0036] In this embodiment, the fixing device is driven to rotate by the gravity of the upper box, and mechanical locking is achieved by the hook plate 4. Finally, the angle adjustment component 5 is used for elastic compensation to ensure a firm fixation.

[0037] In this embodiment, the fixing device is installed between the upper and lower box-shaped rooms. There is no need to pre-embed parts in the structure of the box-shaped rooms. Assembly can be achieved using its own upper and lower crossbeams. At the same time, during assembly, only a hoisting device is needed to stack the box-shaped rooms vertically and horizontally, and staggered installation in the length direction can also be achieved to meet various combination installation requirements, while also reducing costs.

[0038] The fixing device provided in this embodiment only requires on-site screw fixing and flipping operations, making installation convenient; when the container rooms are stacked, the hook plate 4 provides self-locking. The angle adjustment component 5 can be used to elastically compensate for tolerances, reducing production accuracy and installation requirements, while ensuring the alignment accuracy and firmness of the stacked container rooms.

[0039] This embodiment also provides a container house, on which an assembly surface for assembly with another container house is provided with a fixing device as described above. The top of the container house is the assembly surface for installing the other container house. The fixing device is first installed on a crossbeam of this assembly surface, and then, when the other container house is lowered from top to bottom, the two container houses are fixedly connected together by the fixing device.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
