Description

Technical Field

[0001] The present application belongs to the field of building technology, and in particular relates to a steel structure for assembled buildings. Background Art

[0002] Prefabricated buildings refer to buildings that are assembled on site using prefabricated components. The advantages of this type of building are fast construction, less restrictions on climatic conditions, labor savings and improved building quality. Everyone will be able to DIY design and build their own house, and because the house can be disassembled repeatedly, the steel and plates that make up the house can be reused, which can reduce the generation of construction waste.

[0003] The current prefabricated steel structure is generally directly welded or fixed by bolts during use. The publication number is CN219863203U, which discloses a prefabricated steel structure for high-rise buildings, including columns, longitudinal beams and cross beams. Both sides of the two side surfaces of the outer wall of the column are fixedly connected with a first docking seat, and both sides of the two side surfaces of the inner wall of the column are fixedly connected with a second docking seat. Long connecting bolts are inserted on both sides of the column.

[0004] In the above patent, the fixing is performed by the cooperation between the first connecting bolt, the long connecting bolt, the first connecting strip hole and the second connecting strip hole. However, various problems may occur during the long-term fixing process of the bolts. For example, the connection parts thereof are easily infiltrated by rainwater, and the bolts may rust. As a result, when the bolts are manually turned for installation and fixing, extra time and effort will be consumed during installation and disassembly, and the work efficiency is low, which needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a prefabricated steel structure for buildings that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a prefabricated steel structure for buildings, comprising:

[0007] Column;

[0008] A first mounting beam, comprising a first beam body and a first mounting hole arranged on the first beam body;

[0009] A second mounting beam, comprising a second beam body and a second mounting hole arranged on the second beam body;

[0010] A mounting assembly, the mounting assembly being used to connect the column, the first mounting beam and the second mounting beam;

[0011] Among them, the column, the first mounting beam and the second mounting beam are all I-shaped steels, the first mounting hole and the second mounting hole are both strip holes, and the mounting assembly cooperates with the first mounting hole and the second mounting hole.

[0012] By adopting the above-mentioned prefabricated steel structure for buildings, the columns, the first mounting beam and the second mounting beam are all I-shaped steels, and the widths of the columns, the first mounting beam and the second mounting beam are adapted, and the first mounting beam and the second mounting beam are both provided with strip holes for matching mounting components, so that during the installation process, accurate docking and fixation between components can be achieved, thereby improving construction efficiency, and the expansion and contraction of the first mounting beam and the second mounting beam can be met, preventing the expansion and contraction forces of the two from being applied to the columns, thereby improving safety.

[0013] At the same time, by setting up the installation components, the components can be firmly connected, and the entire steel structure system can form a stable and strong structure that effectively resists external loads and deformation. In actual construction, the size or position of the components may deviate due to various reasons, and the strip holes can allow a certain degree of adjustment to ensure the installation accuracy and the stability of the overall structure. And because this steel structure adopts a modular design, it can be combined and expanded according to actual needs. Whether it is a small residential or a large commercial building, it can achieve building structures of different sizes and shapes by adjusting the number and position of columns and mounting beams.

[0014] Furthermore, the installation component includes:

[0015] The first mounting structure includes first mounting seats spaced apart on the left and right sides, and a first slot adapted to the first mounting beam is formed between the two first mounting seats;

[0016] The second mounting mechanism comprises second mounting seats spaced apart from each other, with a second slot adapted to the second mounting beam being formed between the two second mounting seats;

[0017] The first mounting seat and the second mounting seat have the same structure.

[0018] The first slot formed between the two first mounting seats in the first mounting structure is adapted to the first mounting beam, ensuring the precise docking of the first mounting beam during installation. The second slot formed between the two second mounting seats in the second mounting structure is adapted to the second mounting beam, also achieving precise docking of the second mounting beam.

[0019] During installation, you only need to insert the mounting beam into the corresponding slot, and then you only need to install the assembly and fix it to achieve quick installation, without complicated operations, which greatly reduces the difficulty of construction and makes the entire connection structure stable and reliable, and can withstand large external forces. Among them, the first mounting seat has the same structure as the second mounting seat, and the same type of mounting seat can be used for different installation requirements, which improves the versatility and flexibility of the mounting assembly, and can also be reused and mass-produced, and can maintain its performance and function during multiple disassembly and reinstallation, realizing the reusability of materials.

[0020] Further: the first mounting structure includes:

[0021] A first fastener, wherein the first mounting seat is mounted on the column via the first fastener;

[0022] A first through hole is provided on each first mounting seat, and the two first through holes are connected to the first mounting hole;

[0023] A second fastener includes a bolt and a nut, wherein the bolt passes through the first mounting hole, the first through hole, and the first mounting hole in sequence and is connected to the nut;

[0024] Wherein, the first fastener penetrates to the other side of the column.

[0025] The first fastener firmly mounts the first mounting seat on the column, ensuring a stable connection between the mounting seat and the column, so that when the mounting beam is subjected to external force, the force can be effectively transmitted to the column through the mounting seat, thereby ensuring the stability of the entire structure. The first through hole on the first mounting seat is connected to the first mounting hole on the first mounting beam, so that the bolt can pass through these holes and be fixed on the nut, ensuring the precise docking between the mounting beam and the mounting seat, and improving the accuracy of the installation process. At the same time, since the first mounting hole is a strip hole, the second fastener composed of bolts and nuts can be fine-tuned along the length direction of the strip hole to meet the expansion and contraction of the first mounting beam and the second mounting beam, preventing the expansion and contraction force of both from being applied to the column, thereby improving safety. The second fastener composed of bolts and nuts makes the installation and disassembly process simple and quick. By tightening or loosening the nut, the mounting beam can be easily fixed or released, thereby improving construction efficiency.

[0026] In addition, the first fastener passes through the other side of the column, which can be used to fix the first mounting seat and can also be used to limit the second mounting seat, increasing the stability and safety of the mounting structure. It can effectively prevent the mounting seat from loosening or falling off when subjected to external force, thereby ensuring the safety of the entire structure.

[0027] Furthermore, the first mounting structure further includes:

[0028] A contact ring, provided on the bolt;

[0029] A limiting ring groove is arranged on the first through hole;

[0030] A spring is arranged between the contact ring and the limiting ring groove;

[0031] The hole diameter of the first mounting hole is larger than the diameter of the bolt, and a limiting hole for the screw to pass through is arranged in the limiting ring groove.

[0032] Through the arrangement of the contact ring, the limiting ring groove and the spring, when the first mounting beam is installed, as the bolt is gradually tightened, the contact ring gradually approaches the limiting ring groove and squeezes the spring, and the spring abuts against and applies pressure to the contact ring and the limiting ring groove after being squeezed, thereby having a tightening effect on the fixation of the first mounting beam. When the first mounting beam is disassembled, the bolt is loosened, and at this time the spring is reset and provides elastic force to the contact ring and the limiting ring groove, so that it is convenient for the user to loosen the bolt, thereby improving the disassembly efficiency and facilitating the overall installation work.

[0033] Furthermore, the first fastener is a long bolt, two second mounting holes are provided, the first fastener passes through the second mounting hole, and the second mounting hole is slidably connected to the first fastener.

[0034] The first fastener is designed with a long bolt and passes through the second mounting hole. This method strengthens the connection stability between the column and the second mounting beam. There are two second mounting holes, which are slidably connected to the first fastener. This design allows fine-tuning during the installation process to adapt to different installation positions and angle requirements. The sliding connection method can meet the expansion and contraction of the first mounting beam and the second mounting beam, prevent the expansion and contraction force of both from being applied to the column, and improve safety. At the same time, the design of the long bolt passing through the two second mounting holes increases the redundancy of the connection and improves the safety of the structure. Even if one of the connection points becomes loose or damaged, the other connection point can still maintain the stability of the structure and reduce the occurrence of accidents.

[0035] Furthermore, gaskets are provided on both the first fastener and the second fastener.

[0036] The gasket increases the contact area between the fastener and the connecting part, thereby increasing the friction force, preventing the fastener from loosening when subjected to vibration or external force, improving the stability of the connection, and preventing the bolt from directly contacting the first mounting seat and the second mounting seat, reducing wear and corrosion and extending the service life. If the gasket is worn or damaged, it can be easily replaced without replacing the entire fastener. This reduces maintenance costs and improves the maintainability of the structure.

[0037] The beneficial effects of this application are:

[0038] 1. By setting up the installation components, the various components can be firmly connected, and the entire steel structure system can form a stable and strong structure, which can effectively resist external loads and deformation. The second fastener composed of bolts and nuts makes the installation and disassembly process simple and quick. By tightening or loosening the nuts, the installation beam can be easily fixed or released, thereby improving the construction efficiency;

[0039] 2. The steel structure adopts a modular design and can be combined and expanded according to actual needs. Whether it is a small residential building or a large commercial building, the number and position of columns and installation beams can be adjusted to achieve building structures of different scales and shapes;

[0040] 3. Through the arrangement of the contact ring, the limit ring groove and the spring, when the first mounting beam is installed, as the bolts are gradually tightened, the contact ring gradually approaches the limit ring groove and squeezes the spring. After being squeezed, the spring abuts against and applies pressure to the contact ring and the limit ring groove, thereby tightening the first mounting beam. When disassembling the first mounting beam, the bolts are loosened. At this time, the spring is reset and provides elastic force to the contact ring and the limit ring groove, making it easier for the user to loosen the bolts, thereby improving the disassembly efficiency and facilitating the overall installation work.

[0056] At the same time, by setting the installation components, the components can be firmly connected, and the entire steel structure system can form a stable and firm structure, effectively resisting external loads and deformation. In actual construction, the size or position of the components may deviate due to various reasons, and the strip holes can allow a certain degree of adjustment, thereby ensuring the installation accuracy and the stability of the overall structure. And because this steel structure adopts a modular design, it can be combined and expanded according to actual needs. Whether it is a small residential building or a large commercial building, it can achieve building structures of different sizes and shapes by adjusting the number and position of the columns 100 and the installation beams.

[0057] Embodiment 2:

[0058] An embodiment of the present application provides a prefabricated steel structure for buildings. In addition to the above-mentioned technical features, the prefabricated steel structure for buildings in the embodiment of the present application also includes the following technical features.

[0059] like Figures 1 to 3 As shown, the installation components include:

[0060] The first mounting structure 400 includes first mounting seats 410 spaced apart from each other, and a first slot adapted to the first mounting beam 200 is formed between the two first mounting seats 410;

[0061] The second mounting mechanism 500 includes second mounting seats 510 spaced apart from each other, and a second slot adapted to the second mounting beam 300 is formed between the two second mounting seats 510;

[0062] The first mounting seat 410 and the second mounting seat 510 have the same structure.

[0063] In the embodiment of the present application, the first slot formed between the two first mounting seats 410 in the first mounting structure 400 is adapted to the first mounting beam 200, ensuring the precise docking of the first mounting beam 200 during installation. The second slot formed between the two second mounting seats 510 in the second mounting mechanism 500 is adapted to the second mounting beam 300, also achieving the precise docking of the second mounting beam 300.

[0064] During installation, it is only necessary to insert the mounting beam into the corresponding slot, and then only the mounting assembly needs to be fixed to achieve quick installation, without complicated operations, which greatly reduces the difficulty of construction, and can also make the entire connection structure stable and reliable, and can withstand large external forces. Among them, the first mounting seat 410 and the second mounting seat 510 have the same structure, and the same type of mounting seat can be used for different installation requirements, which improves the versatility and flexibility of the mounting assembly, and can also be reused and mass-produced, and can maintain its performance and function during multiple disassembly and reinstallation, realizing the reusability of materials.

[0065] Embodiment 3:

[0066] An embodiment of the present application provides a prefabricated steel structure for buildings. In addition to the above-mentioned technical features, the prefabricated steel structure for buildings in the embodiment of the present application also includes the following technical features.

[0067] like Figures 1 to 3 As shown, the first mounting structure 400 includes:

[0068] A first fastener 420 , wherein the first mounting seat 410 is mounted on the column 100 via the first fastener 420 ;

[0069] A first through hole 430 is provided on each first mounting seat 410 , and two first through holes 430 are connected to the first mounting hole 220 ;

[0070] The second fastener 440 includes a bolt and a nut, wherein the bolt passes through the first mounting hole 220, the first through hole 430, and the first mounting hole 220 in sequence and is connected to the nut;

[0071] The first fastener 420 penetrates to the other side of the column 100 .

[0072] In the embodiment of the present application, the first fastener 420 firmly mounts the first mounting seat 410 on the column 100, ensuring a stable connection between the mounting seat and the column 100, so that when the mounting beam is subjected to external force, the force can be effectively transmitted to the column 100 through the mounting seat, thereby ensuring the stability of the entire structure. The first through hole 430 on the first mounting seat 410 is connected to the first mounting hole 220 on the first mounting beam 200, so that the bolt can pass through these holes and be fixed on the nut, ensuring the precise docking between the mounting beam and the mounting seat, and also improving the accuracy of the installation process. At the same time, since the first mounting hole 220 is a strip hole, the second fastener 440 composed of a bolt and a nut can be fine-tuned along the length direction of the strip hole to meet the expansion and contraction of the first mounting beam 200 and the second mounting beam 300, preventing the expansion and contraction force of both from being applied to the column 100, thereby improving safety. The second fastener 440 composed of a bolt and a nut makes the installation and disassembly process simple and quick, and the installation beam can be conveniently fixed or released by tightening or loosening the nut, thereby improving construction efficiency.

[0073] In addition, the first fastener 420 passes through the other side of the column 100, which can be used to fix the first mounting seat 410 and can also be used to limit the second mounting seat 510, thereby increasing the stability and safety of the mounting structure and effectively preventing the mounting seat from loosening or falling off when subjected to external force, thereby ensuring the safety of the entire structure.

[0074] The first mounting structure 400 further includes:

[0075] A contact ring 450 is provided on the bolt;

[0076] The limiting ring groove 460 is provided on the first through hole 430;

[0077] The spring 470 is disposed between the contact ring 450 and the limiting ring groove 460;

[0078] The hole diameter of the first mounting hole 220 is larger than the diameter of the bolt, and a limiting hole for the screw to pass through is arranged in the limiting ring groove 460 .

[0079] Through the arrangement of the contact ring 450, the limiting ring groove 460 and the spring 470, when the first mounting beam 200 is installed, as the bolts are gradually tightened, the contact ring 450 gradually approaches the limiting ring groove 460 and squeezes the spring 470. After being squeezed, the spring 470 abuts against and applies pressure to the contact ring 450 and the limiting ring groove 460, thereby having a tightening effect on the fixation of the first mounting beam 200. When the first mounting beam 200 is disassembled, the bolts are loosened, and at this time, the spring 470 is reset and provides elastic force to the contact ring 450 and the limiting ring groove 460, so that it is convenient for the user to loosen the bolts, thereby improving the disassembly efficiency and facilitating the overall installation work.

[0080] Embodiment 4:

[0081] An embodiment of the present application provides a prefabricated steel structure for buildings. In addition to the above-mentioned technical features, the prefabricated steel structure for buildings in the embodiment of the present application also includes the following technical features.

[0082] like Figures 1 to 3 As shown, the first fastener 420 is a long bolt, two second mounting holes 320 are provided, the first fastener 420 passes through the second mounting hole 320 , and the second mounting hole 320 is slidably connected to the first fastener 420 .

[0083] In the embodiment of the present application, the first fastener 420 is designed with a long bolt and passes through the second mounting hole 320. This method strengthens the connection stability between the column 100 and the second mounting beam 300. There are two second mounting holes 320, which are slidably connected to the first fastener 420. This design allows fine-tuning during the installation process to adapt to different installation positions and angle requirements. The sliding connection method can meet the expansion and contraction of the first mounting beam 200 and the second mounting beam 300, prevent the expansion and contraction force of both from being applied to the column 100, and improve safety. At the same time, the design of the long bolt passing through the two second mounting holes 320 increases the redundancy of the connection and improves the safety of the structure. Even if one of the connection points becomes loose or damaged, the other connection point can still maintain the stability of the structure and reduce the occurrence of accidents.

[0084] Furthermore, a gasket 600 is disposed on both the first fastener 420 and the second fastener 440 .

[0085] In some embodiments of the present application, the gasket 600 increases the contact area between the fastener and the connecting component, thereby increasing the friction force, preventing the fastener from loosening when subjected to vibration or external force, improving the stability of the connection, and preventing the bolt from directly contacting the first mounting seat 410 and the second mounting seat 510, thereby reducing wear and corrosion and extending the service life. If the gasket 600 is worn or damaged, it can be easily replaced without replacing the entire fastener. This reduces maintenance costs and improves the maintainability of the structure.

[0086] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
