Description

Technical Field

[0001] This utility model relates to the field of modular building technology, and in particular to a modular building roof component with folding support beams. Background Technology

[0002] Modular buildings are prefabricated buildings assembled on-site from modular units. A modular unit is a three-dimensional spatial unit with building functions, composed of prefabricated steel main structure, enclosure walls, floor slab, roof slab, interior components, equipment pipelines, etc. In order to reduce on-site construction, the installation of the roof should minimize the installation process. Existing modular house roofs are installed using finished roofs or by prefabricating the various parts of the roof and then installing them on-site.

[0003] A search revealed Chinese Patent Publication No. CN211949140U, which discloses a modular building roof. When applied to modular buildings, limiting beams are installed on two opposing and symmetrical wall panels. Suspension bodies are installed at the bottom of the roof panel, and then the two ends of each suspension body are aligned and embedded into the fitting grooves of the two opposing limiting beams until the roof panel abuts against the top walls of the limiting beams, limiting blocks, and mounting plates. This invention allows for quick and convenient installation of the roof panel, enabling rapid installation of a sheltered roof for modular buildings.

[0004] However, in actual use, the shape of the prefabricated roof panel cannot be changed. For some temporary buildings or buildings that need to be frequently disassembled and reassembled, such as exhibition halls, temporary medical facilities, and disaster relief tents, it is difficult to adapt to the changing usage scenarios, which makes it impossible to meet the usage needs at different times and locations, and reduces the freedom of architectural design. The large size of the roof component also makes transportation and storage inconvenient. Therefore, a modular building roof component with folding support beams is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular building roof component with folding support beams, which aims to improve the problem that the shape of the existing modular roof components cannot be changed and cannot adapt to different usage scenarios.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular building roof component with folding support beams, including a left top plate, a right top plate being hinged to the right side of the left top plate via a double-axis heavy-duty hinge, crossbeams being fixedly connected to the bottom surfaces of both the left and right top plates, screw holes being provided on the front sides of the crossbeams, a connecting beam being provided at the bottom of the hinge joint between the left and right top plates, a rain shield being provided above the hinge joint between the left and right top plates, and side plates being provided on both the left and right surfaces of the rain shield.

[0007] As a further description of the above technical solution:

[0008] A gap is left between the crossbeams at the bottom of the left and right top plates.

[0009] As a further description of the above technical solution:

[0010] The left and right ends of the connecting beam are respectively detachably connected to the interior of the bolt holes on the crossbeam located below the left and right top plates by bolts.

[0011] As a further description of the above technical solution:

[0012] The side plates on the left and right sides of the rain shield are detachably connected to the upper surfaces of the left and right top plates respectively by bolts.

[0013] As a further description of the above technical solution:

[0014] The upper surfaces of both the left and right top plates are inclined downwards toward the side away from the hinge.

[0015] As a further description of the above technical solution:

[0016] The bottom surface of the rain shield is in contact with the upper surfaces of the left and right top plates, respectively.

[0017] As a further description of the above technical solution:

[0018] The bottom surface of the rain shield is fixedly connected with wedge-shaped strips on both the left and right sides, and the upper surfaces of the left and right top plates are provided with wedge-shaped grooves.

[0019] As a further description of the above technical solution:

[0020] The two wedge-shaped strips on the left and right sides of the bottom of the rain shield are respectively inserted into the wedge-shaped grooves above the left and right top plates, and the cross-section of the wedge-shaped strips is set in an isosceles trapezoid.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the left and right top plates and the corresponding crossbeams can be folded together by the combination of the screw holes, connecting beams, rain shields and side plates. The angle between the left and right top plates can be flexibly adjusted, which can greatly reduce the volume of the roof components during transportation and storage, reduce transportation and storage costs, and flexibly adjust the angle of the roof to adapt to different architectural styles, topography and spatial layout, providing greater freedom for architectural design.

[0023] 2. In this utility model, the wedge-shaped strip and wedge-shaped groove are used to guide and limit the installation of the rain shield, so that the side plate can be more stably aligned with the pre-set threaded holes of the left and right top plates, reducing the installation difficulty, and further limiting the left and right top plates, thereby improving the stability of the roof components.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a modular building roof component with a folding support beam, including a left roof panel 1. A right roof panel 2 is hinged to the right side of the left roof panel 1 via a double-axis heavy-duty hinge. The left roof panel 1 and the right roof panel 2 can be folded upwards or downwards in both directions via the double-axis heavy-duty hinge. The double-axis heavy-duty hinge includes a main hinge axis and a secondary hinge axis. Each axis is equipped with an independent mechanical lock (such as a pin or hydraulic lock) to ensure stability after unfolding. It is made of high-strength steel / aluminum alloy. The bearing part uses self-lubricating bushings or needle roller bearings to reduce friction. This is a prior art in the field and will not be described in detail here. Since there is no obstruction above the left roof panel 1 and the right roof panel 2 after the rain shield 6 is removed, the left roof panel 1 and the right roof panel 2 can be folded upwards and fitted together, greatly reducing the volume.

[0033] The upper surfaces of the left top plate 1 and the right top plate 2 are both inclined downwards towards the side away from the hinge. When rainwater falls on the left top plate 1 and the right top plate 2, it can slide down along the upward inclined surface, so that the rainwater is away from the hinge. The bottom surfaces of the left top plate 1 and the right top plate 2 are both fixedly connected to the crossbeams 3. There is a gap between the crossbeams 3 at the bottom of the left top plate 1 and the right top plate 2 to avoid obstruction when the left top plate 1 and the right top plate 2 are bent downwards to adjust the angle, thereby avoiding structural interference. The front side of the crossbeams 3 is provided with screw holes 4. The bottom of the hinge of the left top plate 1 and the right top plate 2 is provided with a connecting beam 5. The left and right ends of the connecting beam 5 are respectively detachably connected to the inside of the screw holes 4 on the crossbeams 3 located below the left top plate 1 and the right top plate 2 by bolts.

[0034] The connecting beam 5 is horizontally connected to the crossbeams 3 at the bottom of the left top plate 1 and the right top plate 2 by bolts, forming a rigid frame to prevent the roof from lateral deformation or collapse due to external forces (such as wind load and snow load) when it is in the unfolded state, thus improving the overall stability of the structure. At the same time, the length of the connecting beam 5 can be selected according to the distance between the bolt holes 4 on the two corresponding crossbeams 3. When the left top plate 1 and the right top plate 2 are bent and adjusted, the corresponding length of the connecting beam 5 can be quickly replaced to ensure the stability of the roof component. There are several crossbeams 3, which are fixedly connected to the bottom surface of the left top plate 1 and the right top plate 2 in a straight array. The number of connecting beams 5 and the number of crossbeams 3 are matched to each other, which can provide support and limit at multiple positions at the bottom of the left top plate 1 and the right top plate 2, thereby improving the stability of the component.

[0035] Reference Figure 3 and Figure 5A rain shield 6 is installed above the hinge joint of the left top plate 1 and the right top plate 2. The bottom surface of the rain shield 6 is in contact with the upper surfaces of the left top plate 1 and the right top plate 2, respectively. The rain shield 6 can protect the area above the hinge joint from rainwater, preventing rainwater from contacting the double-axis heavy-duty hinge and affecting its service life. Side plates 7 are provided on both the left and right sides of the rain shield 6. The side plates 7 on the left and right sides of the rain shield 6 are detachably connected to the upper surfaces of the left top plate 1 and the right top plate 2 by bolts. The rain shield 6 is detachably connected above the hinge joint by the side plates 7 and bolts. The shape of the rain shield 6 is pre-produced in various ways and can be selected according to the angle adjustment between the left top plate 1 and the right top plate 2 (e.g., Figure 5 As shown, the bottom left and right sides of the rain shield 6 can be kept in contact with the upper surfaces of the left top plate 1 and the right top plate 2 to maintain the limiting position of the left top plate 1 and the right top plate 2. The rain shield 6 can also further limit the position between the left top plate 1 and the right top plate 2. After adjusting the angle between the left top plate 1 and the right top plate 2, and connecting the crossbeams 3 on the left and right sides through the connecting beam 5, the rain shield 6 can be installed, so that the rain shield 6 further limits the position above the hinge between the left top plate 1 and the right top plate 2, further improving the stability of the roof component.

[0036] Reference Figures 2-3 The bottom left and right sides of the rain shield 6 are fixedly connected with wedge strips 8. The upper surfaces of the left top plate 1 and the right top plate 2 are provided with wedge grooves 9. The two wedge strips 8 on the left and right sides of the bottom of the rain shield 6 are respectively inserted into the wedge grooves 9 above the left top plate 1 and the right top plate 2. The cross-section of the wedge strip 8 is set in an isosceles trapezoid. The wedge strip 8 can be inserted into the wedge groove 9 through the front and rear sides. At the same time, the isosceles trapezoidal structure of the wedge strip 8 can prevent it from falling off from the wedge groove 9. When installing the rain shield 6, the wedge strip 8 can be inserted into the wedge groove 9 first to initially limit the position of the rain shield 6, so that the side plate 7 can be better aligned with the pre-set threaded holes above the left top plate 1 and the right top plate 2, reducing the installation difficulty. At the same time, after the wedge strip 8 enters the wedge groove 9, it can further improve the connection stability between the rain shield 6 and the left top plate 1 and the right top plate 2, thereby improving the limiting effect.

[0037] Working principle: When transporting or storing the roof components, the left top panel 1 and right top panel 2 can be folded upwards using a dual-axis heavy-duty hinge, bringing their upper surfaces closer together. This allows the roof to be folded, facilitating transportation and storage and reducing space occupation. When the roof components need to be used, the left top panel 1 and right top panel 2 can be rotated open to the desired installation angle. Then, a rain shield 6 that matches the current angle is selected, and the two wedge-shaped strips 8 at the bottom of the rain shield 6 are inserted into the wedge-shaped grooves 9 above the left top panel 1 and right top panel 2. At this time, the rain shield 6 and the wedge strips 8 can initially limit the left top panel 1 and right top panel 2, maintaining the current bending angle between them. Then, the rain shield 6 is installed above the hinge point using bolts and side panels 7 for rain protection. Afterward, the corresponding length of the connecting beam 5 can be taken and connected to the corresponding two crossbeams 3 on the left and right sides to form a rigid frame, preventing the roof from collapsing due to external forces when unfolded.

[0038] The angle between the left top plate 1 and the right top plate 2 can be adjusted as needed, and the position of the corresponding crossbeam 3 will change accordingly. Only the rain shield 6 and connecting beam 5 that are adapted to the current angle need to be replaced. Compared with replacing the entire roof component, the cost is lower, it can better adapt to different usage scenarios, facilitate quick assembly and disassembly, meet the usage needs of different times and locations, and flexibly adjust the angle and shape of the roof, providing greater freedom for architectural design.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
