Description

Technical Field

[0001] This invention relates to the field of building structure technology, specifically to a stable prefabricated steel structure building and its installation method. Background Technology

[0002] Steel structure buildings are structures whose load-bearing structures are made of structural steel. They typically consist of beams, columns, trusses, and other components made of shaped steel and steel plates. Together with the roof, floors, and walls, they form a complete building. Structural steel usually refers to hot-rolled angle steel, channel steel, I-beams, H-beams, and steel pipes. Buildings whose load-bearing structures are composed of these components are called steel structure buildings. Additionally, load-bearing structures made of thin-walled steel sections (L-shaped, U-shaped, Z-shaped, and tubular, with or without rolled edges) formed from cold-rolled thin steel plates, as well as components made from these sections and smaller steel materials such as angle steel and reinforcing bars, are generally called light steel structure buildings. Cable-stayed structures using steel cables also belong to the category of steel structure buildings. Steel has high strength and modulus of elasticity, uniform material composition, and produces steel structures with good plasticity and toughness, high precision, convenient installation, high industrialization, and fast construction.

[0003] Steel structures are also commonly used in some factory buildings. A typical example is in high-speed rail construction, where the entire line uses bridges as its foundation. Therefore, during construction along the entire line, precast box girders need to be continuously produced and then erected on the bridge piers. The fabrication of the box girders requires the construction of temporary steel structure workshops. Since the entire line is constructed in sections, the workshops need to be moved whenever a section of bridge is completed. Therefore, during the construction of the entire line, temporary workshops need to be continuously built along the line, requiring constant dismantling and reconstruction. Existing steel workshops... When constructing a steel factory, the various structural components are usually connected by bolts. In areas where strength needs to be ensured, welding is used. This assembly method is suitable for factories that do not need to be moved frequently, but it is more troublesome for steel factories that need to be dismantled and reassembled frequently. This is especially true during the construction of the railway line mentioned above, where the entire temporary factory needs to be moved constantly according to the construction progress. Therefore, steel factories used in such places must have the characteristic of rapid assembly, which is difficult for existing steel structure factories to meet. Summary of the Invention

[0004] The purpose of this invention is to provide a stable prefabricated steel structure building and its installation method in order to solve the problems mentioned above in the background art.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A stable prefabricated steel structure building, wherein the components of the steel structure building include at least supporting columns, a first connecting beam and a second connecting beam fixedly disposed on both sides of the supporting columns, an arched beam, and supporting beams; wherein, Both ends of the arched beam are provided with a first T-shaped block, with no less than two of them, and they are parallel to each other in length. One side of the end of the first connecting beam and one side of the end of the second connecting beam are provided with a first T-shaped groove for accommodating the first T-shaped block, and they are parallel to the support column in length. Both ends of the arched beam are provided with extension blocks, and there are no fewer than two of them. When several first T-shaped blocks at the same end of the arched beam are completely contained in several first T-shaped grooves, the several extension blocks overlap with the first connecting beam and the second connecting beam respectively. The arched beam has an installation groove on its arched side, the width of which corresponds to the thickness of the supporting beam.

[0006] Furthermore, the end of the first connecting beam is provided with a second T-shaped block, and the end of the second connecting beam is provided with a second T-shaped groove for accommodating the second T-shaped block. The length of the second T-shaped block and the second T-shaped groove are parallel to the length of the support column. When several extension blocks at the same end of the arch beam overlap with the first connecting beam and the second connecting beam respectively, the second T-shaped block is completely accommodated in the second T-shaped groove.

[0007] Furthermore, the extension block includes an integrally connected overlapping portion and a locking portion. The overlapping portion is connected to the arched beam, and a gap is formed between the locking portion and the end of the arched beam. The widths of the first connecting beam and the second connecting beam are the same as the width of the gap. When several first T-shaped blocks at the same end of the arched beam are completely accommodated in several first T-shaped slots, and when the second T-shaped block is completely accommodated in the second T-shaped slot, the first connecting beam or the second connecting beam is completely accommodated in the gap, and the overlapping portion is in contact with the first connecting beam or the second connecting beam.

[0008] Furthermore, the length of the first T-shaped block, the first T-shaped groove, the second T-shaped block, and the second T-shaped groove is greater than twice the width of the first connecting beam and the second connecting beam.

[0009] Furthermore, the upper structure of the support beam has a snap-fit ​​groove, the width of which corresponds to the mounting groove.

[0010] Furthermore, the two ends of the support beam are respectively constructed with a third T-shaped block and a third T-shaped groove for accommodating the third T-shaped block.

[0011] Furthermore, the arched beam includes two parallel and symmetrical arched plates and a plurality of connecting blocks connecting the two arched plates. The first T-shaped block is evenly distributed at both ends of the two arched plates, and the snap-fit ​​groove is constructed on the arched side of the arched plate.

[0012] This invention also proposes an installation method for a stable prefabricated steel structure building, comprising the following steps: Multiple support columns are divided into several groups and vertically fixed on the ground. The multiple support columns in each group are linearly distributed, and the multiple first connecting beams and second connecting beams are collinear, so that the second T-shaped blocks on each adjacent first connecting beam and the second T-shaped grooves on the second connecting beam engage with each other. An arched beam is placed between every two opposing support columns, such that all the first T-shaped blocks at the ends of the arched beam engage with several first T-shaped slots. Place the support beam on the arched beam and make the mounting groove and the snap-fit ​​groove interlock.

[0013] Furthermore, when engaging the mounting slot with the snap-fit ​​slot, the following steps are also included: Fill the mounting groove with rigid adhesive material and then engage the snap-fit ​​groove with the mounting groove. The adhesive material is heated using heating equipment to heat it.

[0014] Furthermore, when fixing the support column, at least the following steps are included: Dig installation holes in the ground and fix the bottom of the support column into the installation holes; The mounting holes are filled with concrete.

[0015] The beneficial effects of this invention are as follows: In the steel structure building provided by this invention, the mutual cooperation between the first T-shaped block and the first T-shaped groove allows an arched beam to simultaneously connect with multiple supporting columns. Therefore, during the installation of the entire steel structure factory building, only the installation of the arched beam and supporting columns is required to complete the main structure installation of the entire frame. The final top installation is then completed through the interlocking and fixing of the installation groove and the snap-fit ​​groove. In the entire steel structure frame installation, the multiple interlocking designs eliminate the need for bolts and welding. Compared with existing steel structure factory buildings, this design provides a convenient and quick way to disassemble and install, making it very suitable for the design requirements of temporary factory buildings that require frequent disassembly and assembly. Furthermore, this structure reduces bolt consumption and the use of a large amount of equipment during assembly, thus minimizing assembly costs.

[0016] In the steel structure building provided by the present invention, by setting a second T-shaped block and a second T-shaped groove at the ends of the first connecting beam and the second connecting beam respectively, the stability of the two support columns can be further improved through the snap-fit ​​relationship between the two, thereby ensuring the overall strength requirements after installation and reducing swaying.

[0017] The installation method provided by this invention first fixes the support columns to facilitate the installation of subsequent components. Then, by utilizing the snap-fit ​​connection of the arched beams during installation, multiple support columns can be fixed simultaneously, thereby quickly securing the entire main frame. The snap-fit ​​connection between the installation slot and the snap-fit ​​slot allows for the rapid installation of the support beams, thus completing the installation of the entire structure. This method, combined with the steel structure provided by this invention, compared with some conventional installation methods for assembling steel structures, allows for faster installation of the overall structure while reducing material waste during installation, such as bolts, screws, and welding wire.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figures 1-6As shown in the figure, an embodiment of the present invention proposes a stable prefabricated steel structure building. This structure is only a frame structure. During use, the top still needs to be fully enclosed with sheet metal structures such as steel sheets. In existing structures, the main body of the factory building is also composed of steel structures. For some local and scattered parts, sheet metal structures are still needed to complete them. To ensure a certain sealing requirement for the entire structure, the main focus is on the top. The time consumed during the installation of the existing structure is mainly in the installation of the entire main frame. Therefore, the steel structure building provided by this design is mainly used to replace the existing main frame structure to improve the assembly and disassembly speed of the entire factory building. The steel structure building provided by this design is an arched factory building structure composed of multiple components. The specific components include at least a support column 1, a first connecting beam 2 and a second connecting beam 3 fixedly set on both sides of the support column 1, an arched beam 4, and a support beam 5. For some local areas, other components can be used to complete the structure. The first connecting beam 2, the second connecting beam 3, and the support column 1 can be integrated as a whole, so it can be regarded as an integral structure. And within this: Both ends of the arched beam 4 are provided with first T-shaped blocks 6, and there are no fewer than two of them. For installation purposes, four are specifically designed here, but the specific number is not limited. All the first T-shaped blocks 6 on the same arched beam 4 are parallel in length. One side of the end of the first connecting beam 2 and one side of the end of the second connecting beam 3 are provided with first T-shaped grooves 7 for accommodating the first T-shaped blocks 6, and their length is parallel to the support column 1, i.e., vertical. Therefore, one arched beam 4 can be connected to four support columns 1 at the same time. Due to the directional relationship, when the support column 1 is placed vertically, the arched beam 4 can be placed from top to bottom to complete the fixation between the four support columns 1. One arched beam 4 and four support columns 1 together form a combination. When multiple combinations are connected together, they form the frame structure of a factory building. The connection between each combination is still made by the arched beam 4. This design makes the wall structure and the top structure of the entire frame adopt the form of interlocking, so that the top structure and the support structure can be easily and quickly disassembled and assembled. Both ends of the arch beam 4 are provided with extension blocks 8, and the number of each extension block 8 is no less than two, but here it is four, but not limited. Each extension block 8 is assigned to a first connecting beam 2 or a second connecting beam 3 on a support column 1 during assembly. When several first T-shaped blocks 6 at the same end of the arch beam 4 are completely accommodated in several first T-shaped grooves 7, that is, when two first T-shaped blocks 6 at the same end are completely accommodated in two adjacent first T-shaped grooves 7, several extension blocks 8 overlap with the first connecting beam 2 and the second connecting beam 3 respectively. That is, at this time, two extension blocks 8 at the same end of the arch beam 4 overlap with the adjacent first connecting beam 2 and the second connecting beam 3 at the same time. Specifically, the extension blocks 8 overlap on the first connecting beam 2 or the second connecting beam 3, thereby cooperating with the above-mentioned interlocking relationship to prevent the arch beam 4 from falling off, thus fixing one arch beam 4 to the four support columns 1 structure, thereby realizing the fixation between multiple combinations. The arched beam 4 has mounting grooves 9 on its arched side, i.e., at the top. The supporting beam 5 is in the shape of a strip. The width of the mounting groove 9 corresponds to the thickness of the supporting beam 5, so the supporting beam 5 can be placed in the mounting groove 9. There are multiple mounting grooves 9, which are evenly distributed sequentially along the arched direction of the arched beam 4. The supporting beam 5 is distributed across the top of the overall structure through the mounting grooves 9, as shown in the figure. Figure 1 As shown; The entire steel structure also requires a sheet metal structure to seal the roof. Similar to existing methods, corrugated steel sheets are laid on top of the support beam 5, thus completing the overall structural installation. Throughout the structure, the installation between the support column 1 and the arch beam 4, as well as between the support beam 5 and the arch beam 4, is achieved through interlocking mechanisms, without the use of bolts or welding. This structure makes the entire building frame very convenient to install and dismantle. During dismantling, simply remove the top sheet metal, then move the support beam 5 and the arch beam 4 upwards and remove them, thus completing the dismantling of the entire structure. This structure is very suitable for factories that require frequent disassembly, reassembly, and relocation, such as the railway construction site mentioned above.

[0021] like Figure 3 and Figure 4As shown, in some embodiments, the end of the first connecting beam 2 is provided with a second T-shaped block 10, and the end of the second connecting beam 3 is provided with a second T-shaped groove 11 for accommodating the second T-shaped block 10. The dimensions of the two are matched. The length of the second T-shaped block 10 and the second T-shaped groove 11 are parallel to the length of the support column 1, that is, they are also in a vertical direction during installation. When several extension blocks 8 at the same end of the arch beam 4 overlap with the first connecting beam 2 and the second connecting beam 3 respectively, that is, when the installation is completed, the second T-shaped block 10 is completely accommodated in the second T-shaped groove 11. Thus, after the whole is installed, there is a locking relationship between each support column 1, which makes the connection between the support columns 1 more stable, thereby further increasing the installation strength of the overall building structure.

[0022] like Figure 3 and Figure 4 As shown, in some embodiments, the extension block 8 includes an integrally connected overlapping portion 12 and a locking portion 13, specifically an integral structure. The overlapping portion 12 is connected to the arched beam 4, and the locking portion 13 forms a gap between itself and the end of the arched beam 4. The overlapping portion 12 is a vertical block shape, parallel to the end face of the arched beam 4, thus creating a gap. The widths of the first connecting beam 2 and the second connecting beam 3 are the same as the width of the gap. The shapes and structures of the first connecting beam 2 and the second connecting beam 3 are completely identical except for the additional second T-shaped block 10 and second T-shaped groove 11. When the arched beam 4 is connected to the arched beam 4... Several first T-shaped blocks 6 at one end are completely accommodated in several first T-shaped grooves 7, and when the second T-shaped block 10 is completely accommodated in the second T-shaped groove 11, the first connecting beam 2 or the second connecting beam 3 is completely accommodated in the interval area, and the overlapping part 12 is in contact with the first connecting beam 2 or the second connecting beam 3. Therefore, the interval area allows the arch beam 4 to have a hugging effect on the first connecting beam 2 and the second connecting beam 3, thereby making the first connecting beam 2 and the second connecting beam 3 less prone to shaking, thereby further increasing the stability of the installation between the support column 1 structure and the arch beam 4.

[0023] like Figure 3 As shown, in some embodiments, the length of the first T-block 6, the first T-groove 7, the second T-block 10, and the second T-groove 11 is greater than twice the width of the first connecting beam 2 and the second connecting beam 3, thereby increasing the effective length and lengthening the effective area during snapping, making it less likely for the whole to experience horizontal swerving force.

[0024] like Figure 5As shown, in some embodiments, the upper structure of the support beam 5 has a snap-fit ​​groove 14. During installation, the position of the snap-fit ​​groove 14 corresponds to that of the mounting groove 9, and the groove width also corresponds to that of the mounting groove 9. This allows the support beam 5 to have a snap-fit ​​relationship with the mounting groove 9 when it is placed in the mounting groove 9, making it less likely to move and thus improving the overall strength.

[0025] like Figure 5 As shown, in some embodiments, the two ends of the support beam 5 are respectively constructed with a third T-shaped block 15 and a third T-shaped groove 16 for accommodating the third T-shaped block 15, so that when multiple collinear support beams 5 are installed, there is also a connection relationship between them, that is, a locking relationship, so that the whole structure is not easy to be displaced under the cooperation of gravity, thereby further increasing the overall structural strength.

[0026] like Figure 6 As shown, in some embodiments, the arched beam includes two parallel and symmetrical arched plates 17 and a plurality of connecting blocks 18 connecting the two arched plates 17, all integrally forged. The first T-shaped block 6 is evenly distributed at the two ends of the two arched plates 17, and the snap-fit ​​groove 14 is constructed on the arched side of the arched plate 17, thereby further improving the strength of the entire arched beam 4 without adding too much constituent material.

[0027] To better facilitate the installation of the steel structure buildings mentioned in the above embodiments, another embodiment of the present invention provides an installation method for a stable prefabricated steel structure building, specifically for the installation between the above structures. This method includes at least the following steps: Divide the multiple support columns 1 into several groups, such as Figure 1 As shown in the figure, the shape of an arched factory building is shown. Several support columns 1 are vertically fixed on the ground. The multiple support columns 1 in each group are linearly distributed, and the multiple first connecting beams 2 and second connecting beams 3 are collinear, thus forming a connecting wall structure. The second T-shaped blocks 10 on each adjacent first connecting beam 2 and the second T-shaped grooves 11 on the second connecting beam 3 interlock with each other, so that the multiple support columns 1 are interlocked and connected to each other to form the two rows shown in the figure. An arched beam 4 is placed between every two opposing support columns 1, specifically vertically downwards, so that all the first T-shaped blocks 6 at the ends of the arched beam 4 engage with several first T-shaped slots 7, thereby fixing the arched beam 4 between all the support columns 1, thus completing the main installation of the entire structure. The whole process is simple and quick. As for the placement of the arched beam, it can be done in conjunction with a crane. The support beam 5 is placed on the arched beam, and the mounting groove 9 and the snap-fit ​​groove 14 are engaged with each other, thus completing the installation of the entire frame. Then, the subsequent installation of the top sheet metal is carried out. The installation of the sheet metal is the same as the existing installation method, which is to lay it down. This completes the installation of the entire steel factory structure. This method, combined with the above building structure, allows the installation of the entire factory to be completed quickly.

[0028] To ensure the stability of the iron sheet structure when fixed on the support beam 5, in some embodiments, when the mounting groove 9 is engaged with the snap-fit ​​groove 14, the following steps are also included: A rigid adhesive material, specifically hot melt rubber, is poured into the mounting groove 9 to engage the snap-fit ​​groove 14 with the mounting groove 9. Heating equipment is used to heat the adhesive material, causing it to heat up and adhere between the mounting groove 9 and the snap-fit ​​groove 14, thereby ensuring the firmness of the connection between the sheet metal structure and the whole, and increasing the wind resistance of the sheet metal.

[0029] To ensure the stability of the support column 1 when fixed on the ground, in some embodiments, fixing the support column 1 includes at least the following steps: Dig an installation hole in the ground and fix the bottom of the support column 1 into the installation hole, that is, drive it into the installation hole; Concrete is poured into the mounting holes, and once the concrete hardens, the support column 1 is firmly fixed to the ground, thus ensuring a strong connection between the whole structure and the ground, and ensuring the solid foundation of the whole structure.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. 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 the invention. Therefore, the invention 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.
