Description

Technical Field

[0001] This application relates to the field of prefabricated roofing technology, and more particularly to a prefabricated roofing structure. Background Technology

[0002] Prefabricated roof structures, as a type of steel structure building, are widely used in industrial plants. These roof structures typically consist of mounting beams, roof connecting beams, and support components, with the overall roof coverage achieved through the assembly of these components. In existing designs, roof beams are generally installed using fixing blocks and bolts, relying on support rods and connectors to maintain roof stability. This assembly method aims to achieve rapid installation and easy maintenance, reducing construction costs and time. However, traditional prefabricated structures have certain drawbacks in practical applications due to design limitations.

[0003] Existing prefabricated roof structures include a Chinese patent (CN216239262U) that discloses a modular steel structure roof. While this patent mentions the use of grooved mounting blocks and support components for connecting roof beams, its design has shortcomings in roof angle adjustment. When the roof angle is adjusted, the existing structure cannot adjust the width of the roof structure in real time according to the needs. Therefore, this type of structure is difficult to meet the roof angle adjustment requirements in changing environments in practical applications, limiting its adaptability and practicality.

[0004] Therefore, it is necessary to propose a modular roof structure to solve the problem that the width of the roof structure cannot be adjusted in real time according to the needs in the existing technology. Utility Model Content

[0005] The purpose of this application is to overcome the shortcomings of the prior art and propose a modular roof structure to solve the problem that the width of the roof structure cannot be adjusted in real time according to the needs in the prior art.

[0006] This application is achieved through the following technical solution:

[0007] This application proposes a modular roof structure, including a ridge structure, a first connecting beam structure, a second connecting beam structure, a first side beam plate, a second side beam plate, and a crossbeam structure. One end of the first connecting beam structure is rotatably connected to the ridge structure, and the other end is rotatably connected to the first side beam plate. One end of a plurality of second connecting beams is rotatably connected to the ridge structure, and the other end is rotatably connected to the second side beam plate. The second connecting beams are located on the side of the ridge structure opposite to the first connecting beam.

[0008] Viewed along the extension direction of the ridge structure, the ridge structure, the first connecting beam structure, the second connecting beam structure, the first side beam plate, and the second side beam plate form a triangular shape;

[0009] One end of the crossbeam structure is located on the first side beam plate, and the other end is located on the second side beam plate. The crossbeam structure can be extended or shortened along the extension direction to adjust the distance between the first side beam plate and the second side beam plate to a predetermined size, thereby realizing the width adjustment of the prefabricated roof structure.

[0010] In one embodiment of this application, the beam structure includes:

[0012] The second crossbeam has one end fixedly connected to the second side beam plate, and the second crossbeam and the first crossbeam are located on the same axis.

[0013] The width adjustment mechanism has its two ends rotatably connected to the first crossbeam and the second crossbeam in opposite directions, respectively. By rotating, it drives the first crossbeam and the second crossbeam to move synchronously, so as to lengthen or shorten the crossbeam structure.

[0017] The second lead screw has one end fixedly connected to the knob and the other end threadedly connected to the second crossbeam;

[0018] The knob, when rotated in the forward direction, drives the first lead screw and the second lead screw to rotate synchronously, causing the first crossbeam and the second crossbeam to move toward each other, thereby shortening the length of the crossbeam structure.

[0019] The knob, by rotating in the opposite direction, drives the first lead screw and the second lead screw to rotate synchronously, causing the first crossbeam and the second crossbeam to move away from each other, thereby extending the length of the crossbeam structure.

[0020] In one embodiment of this application, the first connecting beam structure includes:

[0021] The first connecting beam is rotatably connected at one end to the ridge structure and at the other end to the first side beam plate.

[0022] The second connecting beam is rotatably connected at one end to the ridge structure and rotatably connected at the other end to the first side beam. The second connecting beam is parallel to the first connecting beam and is located below the first connecting beam.

[0030] The second ridge body has one end rotatably connected to the second connecting beam body and the other end rotatably connected to the fourth connecting beam body. The second ridge body is parallel to and fixedly connected to the first ridge body, and the second ridge body is located below the first ridge body.

[0031] In one embodiment of this application, a parallelogram is formed between the ridge structure, the first connecting beam, the second connecting beam, and the first side beam plate;

[0032] When the knob is rotated in the forward or reverse direction, a parallelogram is always formed between the first spine body, the second spine body, the first connecting beam body, the second connecting beam body, and the first side beam plate.

[0033] When the knob is rotated in either the forward or reverse direction, a parallelogram is always formed between the first spine body, the second spine body, the third connecting beam body, the fourth connecting beam body, and the second side beam plate.

[0034] In one embodiment of this application, the first side beam plate and the second side beam plate are always parallel to each other and always perpendicular to the ground.

[0035] In one embodiment of this application, there are multiple first connecting beam structures and multiple second connecting beam structures, and the quantities correspond one-to-one and are distributed at equal intervals.

[0036] In one embodiment of this application, there are multiple beam structures, and the multiple beam structures are distributed at equal intervals.

[0037] Compared with the prior art, the beneficial effects of this application are:

[0038] One end of the first connecting beam structure is rotatably connected to the ridge structure, and the other end is rotatably connected to the first side beam. Multiple second connecting beams have one end rotatably connected to the ridge structure and the other end rotatably connected to the second side beam, with the second connecting beams located on the side of the ridge structure opposite to the first connecting beam. Viewed along the extension direction of the ridge structure, the ridge structure, the first connecting beam structure, the second connecting beam structure, the first side beam, and the second side beam form a triangular shape. One end of the crossbeam structure is located on the first side beam and the other end on the second side beam. The crossbeam structure can be extended or shortened along the extension direction to adjust the distance between the first and second side beams to a predetermined size, thus achieving width adjustment of the prefabricated roof structure. In this way, by setting the telescopic function of the crossbeam structure, the width adjustment of the prefabricated roof structure under different usage scenarios can be achieved. It adapts to various complex architectural needs, whether it's a pitched roof with different angles or various factory layouts, achieving optimal adaptability through adjustment.

[0051] Please refer to Figures 1 to 2 This application proposes a modular roof structure 10, including a ridge structure 100, a first connecting beam structure 200, a second connecting beam structure 300, a first side beam plate 400, a second side beam plate 500, and a crossbeam structure 600. One end of the first connecting beam structure 200 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the first side beam plate 400. One end of a plurality of second connecting beams is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the second side beam plate 500. The second connecting beams are located on the side of the ridge structure 100 away from the first connecting beam.

[0052] Viewed along the extension direction of the ridge structure 100, the ridge structure 100, the first connecting beam structure 200, the second connecting beam structure 300, the first side beam plate 400, and the second side beam plate 500 form a triangular shape; one end of the crossbeam structure 600 is located on the first side beam plate 400, and the other end is located on the second side beam plate 500. The crossbeam structure 600 can be extended or shortened along the extension direction to adjust the distance between the first side beam plate 400 and the second side beam plate 500 to a predetermined size, thereby realizing the width adjustment of the prefabricated roof structure 10.

[0053] Specifically, one end of the first connecting beam structure 200 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the first side beam 400; one end of the second connecting beam structure 300 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the second side beam 500. The second connecting beam is located on the side of the ridge structure 100 away from the first connecting beam, so that the first connecting beam structure 200 and the second connecting beam structure 300 form a symmetrical structure in the extension direction of the ridge structure 100, thereby better maintaining the overall balance and stability during structural adjustments.

[0054] Viewed along the extension direction of the ridge structure 100, the ridge structure 100, the first connecting beam structure 200, the second connecting beam structure 300, the first side beam plate 400, and the second side beam plate 500 form a triangular shape. One end of the crossbeam structure 600 is located on the first side beam plate 400, and the other end is located on the second side beam plate 500. It can extend or shorten along the extension direction, allowing the first connecting beam structure 200 and the second connecting beam structure 300 to move simultaneously, adjusting the distance between the first side beam plate 400 and the second side beam plate 500, thus achieving flexible adjustment of the roof width. By setting the telescopic function of the crossbeam structure 600, the width adjustment of the prefabricated roof structure 10 is realized in different usage scenarios. Compared with existing technologies, the prefabricated roof structure 10 can quickly change the roof width without affecting other components to meet the needs of different factory building structures.

[0055] In one embodiment, the crossbeam structure 600 includes a first crossbeam 610, a second crossbeam 620, and a width adjustment mechanism 630. One end of the first crossbeam 610 is fixedly connected to the first side beam plate 400; one end of the second crossbeam 620 is fixedly connected to the second side beam plate 500, and the second crossbeam 620 and the first crossbeam 610 are located on the same axial direction; the two ends of the width adjustment mechanism 630 are respectively rotatably connected to the first crossbeam 610 and the second crossbeam 620 in opposite directions, and the first crossbeam 610 and the second crossbeam 620 are driven to move synchronously by rotation, so as to lengthen or shorten the crossbeam structure 600.

[0056] Specifically, one end of the first crossbeam 610 is fixedly connected to the first side beam plate 400, and one end of the second crossbeam 620 is fixedly connected to the second side beam plate 500. The first crossbeam 610 and the second crossbeam 620 are located on the same axial direction and are connected to each other by a width adjustment mechanism 630. The two ends of the width adjustment mechanism 630 are rotatably connected to the first crossbeam 610 and the second crossbeam 620 in opposite directions, respectively. This connection method allows the first crossbeam 610 and the second crossbeam 620 to move synchronously by rotating the width adjustment mechanism 630, thereby allowing the crossbeam structure 600 as a whole to extend or shorten, so as to adjust the distance between the first side beam plate 400 and the second side beam plate 500.

[0057] In one embodiment, the width adjustment mechanism 630 includes a knob 631, a first lead screw 632, and a second lead screw 633. One end of the first lead screw 632 is fixedly connected to the knob 631, and the other end is threadedly connected to the first crossbeam 610. One end of the second lead screw 633 is fixedly connected to the knob 631, and the other end is threadedly connected to the second crossbeam 620. By rotating the knob 631 in the forward direction, the first lead screw 632 and the second lead screw 633 are driven to rotate synchronously, causing the first crossbeam 610 and the second crossbeam 620 to move toward each other, thereby shortening the length of the crossbeam structure 600. By rotating the knob 631 in the reverse direction, the first lead screw 632 and the second lead screw 633 are driven to rotate synchronously, causing the first crossbeam 610 and the second crossbeam 620 to move away from each other, thereby lengthening the length of the crossbeam structure 600.

[0058] Specifically, the knob 631 is located at the center of the crossbeam structure 600. One end of the first lead screw 632 is fixedly connected to the knob 631, and the other end is threaded to the first crossbeam 610. Similarly, one end of the second lead screw 633 is fixedly connected to the knob 631, and the other end is threaded to the second crossbeam 620. This connection method ensures that the first lead screw 632 and the second lead screw 633 can move synchronously when the knob 631 is rotated.

[0059] Operation of rotating knob 631 in the forward direction:

[0060] When knob 631 is rotated clockwise, the first lead screw 632 and the second lead screw 633 rotate synchronously. Since the first lead screw 632 and the second lead screw 633 are threadedly connected to the first crossbeam 610 and the second crossbeam 620 respectively, the direction of rotation causes the first crossbeam 610 and the second crossbeam 620 to move towards the center, thereby shortening the overall length of the crossbeam structure 600. This operation reduces the distance between the first side beam plate 400 and the second side beam plate 500, thus achieving a narrowing of the roof structure. This design ensures the symmetry and stability of the roof during reduction, avoiding structural displacement or deformation caused by uneven adjustment.

[0061] Reverse rotation operation of knob 631:

[0062] When knob 631 is rotated in the reverse direction, the first lead screw 632 and the second lead screw 633 rotate synchronously, but in opposite directions. At this time, the first crossbeam 610 and the second crossbeam 620 move in opposite directions, thereby extending the length of the crossbeam structure 600. This operation increases the distance between the first side beam 400 and the second side beam 500, allowing the roof structure to expand. This expansion adjustment also maintains the parallelism of the first side beam 400 and the second side beam 500, ensuring the integrity and stability of the structure during adjustment.

[0063] In one embodiment, the first connecting beam structure 200 includes a first connecting beam body 210 and a second connecting beam body 220. One end of the first connecting beam body 210 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the first side beam plate 400. One end of the second connecting beam body 220 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the first side beam plate 400. The second connecting beam body 220 is parallel to the first connecting beam body 210, and the second connecting beam body 220 is located below the first connecting beam body 210.

[0064] The second connecting beam structure 300 includes a third connecting beam 310 and a fourth connecting beam 320. One end of the third connecting beam 310 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the second side beam 500. One end of the fourth connecting beam 320 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the second side beam 500. The fourth connecting beam 320 is parallel to the third connecting beam 310 and is located below the third connecting beam 310. The fourth connecting beam 320 is perpendicular to the second connecting beam 220. The third connecting beam 310 is perpendicular to the first connecting beam 210.

[0065] Specifically, one end of the first connecting beam 210 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the first side beam 400; one end of the second connecting beam 220 is rotatably connected to the ridge structure 100, and the other end is rotatably connected to the first side beam 400. The second connecting beam 220 is arranged parallel to the first connecting beam 210 and is located below the first connecting beam 210. The fourth connecting beam 320 is perpendicular to the second connecting beam 220, and the third connecting beam 310 is perpendicular to the first connecting beam 210, forming a stable support frame, which avoids the possible twisting or deformation of a single beam when under stress.

[0066] In one embodiment, the ridge structure 100 includes a first ridge body 110 and a second ridge body 120. One end of the first ridge body 110 is rotatably connected to a first connecting beam 210, and the other end is rotatably connected to a third connecting beam 310. One end of the second ridge body 120 is rotatably connected to a second connecting beam 220, and the other end is rotatably connected to a fourth connecting beam 320. The second ridge body 120 and the first ridge body 110 are parallel to each other and fixedly connected. The second ridge body 120 is located below the first ridge body 110. The ridge structure 100, the first connecting beam 210, the second connecting beam 220, and the first side beam 400 form a parallelogram.

[0067] When the knob 631 is rotated in the forward or reverse direction, a parallelogram is always formed between the first spine body 110, the second spine body 120, the first connecting beam 210, the second connecting beam 220, and the first side beam plate 400.

[0068] When the knob 631 is rotated in the forward or reverse direction, a parallelogram is always formed between the first spine body 110, the second spine body 120, the third connecting beam body 310, the fourth connecting beam body 320, and the second side beam plate 500.

[0069] Specifically, the first ridge beam 110 is rotatably connected to the first connecting beam 210 on one side and to the third connecting beam 310 on the other side. The second ridge beam 120 is rotatably connected to the second connecting beam 220 at one end and to the fourth connecting beam 320 at the other end. This ridge beam is arranged parallel to the first ridge beam 110 and fixed beneath it. This design ensures that the first ridge beam 110 and the second ridge beam 120 remain parallel during adjustment, while forming a stable double-layer support structure throughout the roof system. This double-layer parallel arrangement better distributes and bears the load of the roof structure, enhancing the overall stability of the system.

[0070] When the ridge structure 100, the first connecting beam 210, the second connecting beam 220, and the first side beam 400 are connected, they form a parallelogram geometry. This geometric design, through the properties of a parallelogram, ensures that the relative positions of the various parts of the roof remain stable during the adjustment of the crossbeams and side beams.

[0071] When the knob 631 is rotated in either the forward or reverse direction, the first ridge beam 110, the second ridge beam 120, the first connecting beam 210, the second connecting beam 220, and the first side beam 400 maintain a parallelogram relationship. Similarly, the first ridge beam 110, the second ridge beam 120, the third connecting beam 310, the fourth connecting beam 320, and the second side beam 500 also form a parallelogram. This geometric design maintains the symmetry and rigidity of the roof system during the adjustment of the beam structure 600, thereby avoiding structural shifts or instabilities that may occur during the adjustment process.

[0072] In one embodiment, the first side beam plate 400 and the second side beam plate 500 are always parallel to each other and always perpendicular to the ground.

[0073] Specifically, the first side beam 400 and the second side beam 500 always remain parallel to each other and perpendicular to the ground, ensuring that the relative position between the side beams remains unchanged regardless of the adjustment of the roof angle or width.

[0074] The parallel design of the first side beam 400 and the second side beam 500 ensures that they remain symmetrical during the adjustment of the crossbeam structure 600, preventing tilting or shifting. Simultaneously, the perpendicularity of the first side beam 400 and the second side beam 500 to the ground ensures the stability and integrity of the entire roof system at any adjustment position.

[0075] There are multiple first connecting beam structures 200 and multiple second connecting beam structures 300, with each corresponding to the previous one and evenly spaced. There are multiple crossbeam structures 600, all evenly spaced.

[0076] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
