Description

Technical Field

[0001] This utility model relates to the field of factory building technology, specifically to a roof structure with adjustable installation height. Background Technology

[0002] Steel structure roofs are widely used in factories due to their advantages such as high strength and lightweight, fast construction speed, good economy, flexible design, and high space utilization. However, inconsistencies can arise during the installation of steel structure roofs. These inconsistencies stem from multiple stages, including steel structure design, materials, fabrication, transportation, foundation pre-embedding, and installation. Errors can be introduced at each stage, and these errors accumulate and amplify. Excessive height differences in the steel structure roof installation (exceeding the design height error range) can lead to a series of problems, primarily: uneven roof load distribution; water accumulation in low-lying areas, which is prone to corrosion and increases the load on these areas; and noticeable unevenness and undulation of the roof panels, which severely affects the overall appearance of the building.

[0003] In existing technologies, to prevent excessive height differences in steel structure roofs during construction, the main measures typically taken are: strict measurement, correction, and process monitoring during on-site installation. While this approach can prevent excessive height differences in the installation height of steel structure roofs, it requires multiple measurement and correction procedures, resulting in slow construction speed and significant manpower and material costs, thus increasing installation costs. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a roof structure with adjustable installation height, so as to solve the problems of slow construction speed and high construction cost caused by the need for multiple measurement and correction procedures during the construction of existing steel structure roofs to ensure the consistency of roof installation height.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a roof structure with adjustable installation height, including multiple transversely spaced horizontal beams, longitudinal beams, and multiple connecting columns. The longitudinal beams are arranged longitudinally above the multiple horizontal beams. The multiple horizontal beams are respectively fixedly installed at the bottom end of the longitudinal beams through the multiple connecting columns. The opposite ends of the horizontal beams are respectively fixedly connected to the longitudinal beams through trusses. Several sets of height adjustment components are provided between the horizontal beams and the trusses. The several sets of height adjustment components are arranged at intervals along the length direction of the horizontal beams. The height adjustment components are used to adjust the inclination of the trusses relative to the transverse direction.

[0007] Furthermore, the height adjustment assembly includes a connecting frame, a mounting base, bolts, and nuts arranged in a horizontal "U" shape. The bottom end of the mounting base is fixedly installed on the upper surface of the connecting frame. A first opening is provided on one side of the connecting frame. The bolts are vertically installed on the connecting frame on one side of the first opening. The connecting frame is fixedly installed on the upper surface of the crossbeam by the bolts and nuts. A second opening in the shape of a "U" is provided at the upper end of the mounting base. The mounting base has several spaced mounting holes arranged vertically. The mounting holes horizontally penetrate the second opening. One end of the truss has a connecting hole that mates with the mounting holes. One end of the truss is fixedly installed on the mounting base by locking bolts and locking nuts installed on the mounting holes and connecting holes.

[0008] Furthermore, the upper edge of the second opening of the mounting base has an flared shape that expands outwards to both sides.

[0009] Furthermore, the height adjustment assembly also includes an adjustment bracket in the shape of an "L" that rotates 90° clockwise. The bottom end of the adjustment bracket is mounted on the upper end face of the connecting frame, and the bottom end of the mounting base is fixedly mounted on the upper end face of the adjustment bracket. The adjustment bracket and the connecting frame are fixedly mounted on the upper end face of the crossbeam by bolts and nuts.

[0010] Furthermore, an installation groove is provided on the upper end face of the connecting frame at the position opposite to the first opening, and the bottom end of the adjusting bracket is installed in the installation groove.

[0011] Furthermore, the crossbeam is an I-beam.

[0012] The beneficial effects of this utility model are as follows:

[0013] By adopting the aforementioned height-adjustable roof structure, and by installing several sets of height adjustment components between the trusses and beams, arranged along the length of the beams, the trusses can be installed on the beams. After installation, the height adjustment components below each truss are uniformly adjusted to keep the truss's inclination within the designed error range. This ensures the required installation height error range for the steel structure roof. Since the height adjustment is done uniformly after the steel structure roof construction is complete, multiple measurement and correction processes are avoided during construction, ensuring construction progress. Furthermore, by saving on measurement equipment, correction equipment, and labor, construction costs are reduced compared to existing steel structure roof construction methods.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] See appendix Figure 1 To be continued Figure 3As shown, this embodiment provides a roof structure 100 with adjustable installation height, including multiple horizontally spaced crossbeams 10, longitudinal beams 30, and multiple connecting columns 20. The longitudinal beams 30 are arranged directly above the multiple crossbeams 10. Each crossbeam 10 is equipped with a corresponding connecting column 20. The connecting columns 20 are arranged vertically. The bottom end of the connecting column 20 is fixedly installed on the upper end face of the crossbeam 10, and the upper end of the connecting column 20 is fixedly installed on the bottom end of the longitudinal beam 30. That is, the crossbeams 10 are fixedly installed on the longitudinal beams 30 through the connecting columns 20.

[0031] Continue to refer to the appendix Figure 1 To be continued Figure 3 As shown, in this embodiment, the two ends of the crossbeam 10 are respectively connected to the sides of the longitudinal beam 30 by the installed trusses 50. The crossbeam 10 and the pair of trusses 50 form a triangular connection structure, which is beneficial to providing stability for the steel structure roof.

[0032] See attached document Figure 2 and attached Figure 3 As shown, the truss 50 is mounted on the height adjustment component 40 provided on the crossbeam 10. The height adjustment component 40 is used to adjust the installation height of the truss 50 on the crossbeam 10, that is, to adjust the installation tilt of the truss 50 relative to the crossbeam 10.

[0033] For details, please refer to the appendix. Figure 3 To be continued Figure 5 As shown, in this embodiment, the height adjustment assembly 40 includes a connecting frame 41, a mounting base 42, a bolt 47, and a nut 48 arranged in a horizontal "U" shape.

[0034] See attached document Figure 4 and attached Figure 5 As shown, the connecting frame 41 is constructed of steel plate. A first opening 411 is provided on the right side of the connecting frame 41, extending horizontally to the left. The first opening 411 helps reduce the weight of the connecting frame 41, thereby reducing the load acting on the crossbeam 10. It is understandable that creating the first opening 411 on the connecting frame 41 will not affect its load-bearing capacity on the truss 50 and the roof, because steel structure roofs are generally made of corrugated steel sheets, which are relatively thin, and the truss 50 is generally hollow square steel with limited weight. Therefore, creating the first opening 411 on the connecting frame 41 will not affect its normal load-bearing function.

[0035] Continue to refer to the appendix Figure 4 and attached Figure 5As shown, in this embodiment, the bottom end face of the mounting base 42 is fixedly mounted on the upper end face of the connecting frame 41, for example by welding or locking with bolts 47, which is not limited to this method. The upper end of the mounting base 42 has a second opening 43 in the shape of a "U". The mounting base 42 has a plurality of spaced mounting holes 45 arranged vertically. The mounting holes 45 pass horizontally through the second opening 43. One end of the truss 50 has a connecting hole that mates with the mounting hole 45. One end of the truss 50 is fixedly mounted on the mounting base 42 by locking bolts 46 and locking nuts 49 installed on the mounting hole 45 and the connecting hole. The truss 50 is fixed to the mounting base 42 using locking bolts 46 and locking nuts 49. This facilitates the adjustment of the truss 50's installation position on the mounting base 42 by construction personnel. Specifically, by removing the locking nuts 49 and locking bolts 46, replacing the locking bolt 46 with one that is positioned in the corresponding mounting hole 45 on the mounting base 42, the locking bolt 46 is re-passed through the mounting hole 45 on the truss 50, and then tightened with the locking nut 49. This allows for adjustment of the truss 50's installation height within the mounting base 42, making the adjustment simple, convenient, and quick. It is understandable that the vertical spacing between the multiple mounting holes 45 can be flexibly set according to the required adjustment precision. For example, when higher adjustment precision is required, the distance between adjacent mounting holes 45 is smaller.

[0036] By employing individual height adjustment components 40 between the truss 50 and the crossbeam 10, the height adjustment components 40 at each truss 50 can be adjusted individually after the steel structure roof construction is completed, i.e., after the crossbeam 10, longitudinal beam 30, truss 50, and height adjustment components 40 are installed. This adjustment is achieved by adjusting the installation of each truss 50 within the corresponding height position of the mounting hole 45 on the mounting base 42, ensuring that all trusses 50 on the entire steel structure roof are within the design error range. Since the installation height of each truss 50 is measured and adjusted sequentially after the steel structure roof construction is completed, the multiple measurement and correction procedures required during construction are eliminated, thus accelerating the construction progress. Furthermore, the construction cost is reduced by saving on measuring equipment, correction equipment, and labor during the construction process. In addition, adjustment only requires changing the installation height of one end of the truss 50 within the mounting base 42, making adjustment convenient, simple, and quick.

[0037] See attached document Figure 4 and attached Figure 5 As shown, in some embodiments, in order to facilitate the installation of the truss 50 in the second opening 43 on the mounting base 42, the upper edge of the second opening 43 is an flared shape structure 44 that expands outward to both sides, similar to the shape structure of a trumpet mouth.

[0038] See attached document Figure 4 and attached Figure 5As shown, in this embodiment, the connecting frame 41 is fixedly installed on the upper end face of the crossbeam 10 by bolts 47 and nuts 48. That is, one end of the bolt 47 passes vertically upward through the crossbeam 10 and the connecting frame 41, and the nut 48 is tightened at the end of the bolt 47 that passes through the connecting frame 41 to fix the connecting frame 41 to the crossbeam 10. Of course, welding can also be used to fix the connecting frame 41 to the crossbeam 10, which is not a limitation.

[0039] See attached document Figure 6 To be continued Figure 8 As shown, in some embodiments, in order to accommodate the height adjustment of the truss 50 at locations where the height difference between the truss 50 and the crossbeam 10 is large, such as the inner side of the crossbeam 10, i.e., the end of the crossbeam 10 near the longitudinal beam 30. The height adjustment assembly 40 also includes an adjustment bracket 413 with an "L" shape that rotates 90° clockwise. The bottom end of the adjustment bracket 413 is installed on the upper end face of the connecting frame 41. In order to prevent the adjustment bracket 413 from wobbling left and right on the upper end face of the connecting frame 41, an installation groove 412 is provided on the other side of the upper end face of the connecting frame 41 opposite to the first opening 411. The bottom end of the adjustment bracket 413 is installed in the installation groove 412. The adjustment bracket 413 and the connecting frame 41 are fixedly installed on the upper end face of the crossbeam 10 by bolts 47 and nuts 48. That is, one end of the bolt 47 passes vertically through the connecting frame 41 and the adjustment bracket 413 in sequence, and then the nut 48 is tightened at the end of the bolt 47 that passes through the adjustment bracket 413, so that the adjustment bracket 413 and the connecting frame 41 can be fixedly installed on the mounting base 42.

[0040] By providing an adjusting bracket 413, the installation height of the mounting base 42 can be increased, thereby accommodating the height adjustment of the truss 50 located inside the crossbeam 10. That is, for the height adjustment component 40 located inside the crossbeam 10, since the vertical distance between the truss 50 and the crossbeam 10 at this location is relatively large, by adding an adjusting bracket 413 to the connecting frame 41, the mounting base 42 is mounted on the connecting frame 41 via the adjusting bracket 413, thereby increasing the installation height of the mounting base 42 to accommodate the large height difference between the truss 50 and the crossbeam 10 at this location. Thus, when it is necessary to adjust the installation height of the truss 50 at this location, it is only necessary to select the mounting hole 45 at the corresponding height position of the truss 50 on the mounting base 42.

[0041] See attached document Figures 4 to 6 and attached Figure 8 As shown, in this embodiment, the crossbeam 10 is made of I-beam. The reason for prioritizing the use of I-beam is that the space of the slots on both sides of the I-beam can be utilized to facilitate the operation and installation of the bolts 47 on the crossbeam 10.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
