Description

Technical Field

[0001] This invention relates to the field of steel structure technology, and more particularly to a steel structure building. Background Technology

[0002] As an industrialized building system, steel structure meets the requirements of industrialized building standards, including standardized design, factory fabrication, prefabricated construction, and information-based management. Movable steel structure buildings are increasingly widely used in my country's civil construction sector, primarily because steel structures, as a green product in the construction industry, can fully utilize the superior mechanical properties of steel and align with the long-term sustainable development strategy. However, with the widespread development of steel structure buildings, some existing problems with movable steel structure buildings need to be addressed:

[0003] 1. Existing mobile steel structure buildings are usually fixed structures. Due to considerations of mobility, the interior space is usually small, resulting in poor comfort and transportability of the residence.

[0004] 2. Existing mobile steel structure buildings require large cranes to lift them onto vehicles when moving them, which is time-consuming and labor-intensive. Furthermore, multiple people are needed to move them, posing certain safety hazards.

[0005] 3. Existing movable steel structure buildings require additional furniture transportation after relocation. The manual handling of furniture upon arrival is time-consuming, labor-intensive, and increases transportation costs. Summary of the Invention

[0006] The purpose of this invention is to provide a steel structure building that is not only simple in structure but also easy to move.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a steel structure building, comprising a front side plate and a rear side plate, wherein the bottom rear side of the front side plate is provided with a rearwardly extending front sliding sleeve, and the bottom front side of the rear side plate is provided with a forwardly extending rear sliding rod slidably connected within the front sliding sleeve; telescopic plate assemblies are movably connected to the left and right sides of the front side plate and the left and right sides of the rear side plate; side plate assemblies are provided between the telescopic plate assemblies located on the left and right sides of the front side plate and the telescopic plate assemblies located on the left and right sides of the rear side plate; folding plate assemblies are provided between the upper ends and the lower ends of the front side plate and the rear side plate; a power assembly and a transmission assembly connected to the power assembly are provided on the front side of the front side plate and the rear side of the rear side plate, wherein the transmission assembly is used to control the extension or retraction of the telescopic plate assembly, the side plate assembly, and the folding plate assembly.

An upper connecting rod 31 is fixedly mounted on the end face of the upper gear 311. An upper bevel gear 322 is rotatably connected to the first side plate 43. An upper second connecting rod 32 is fixedly mounted on the end face of the upper bevel gear 322. The upper connecting rod 31 and the upper second connecting rod 32 are hinged together. An upper second bevel gear 331, meshing with the upper bevel gear 322, is rotatably connected to the first convex plate 42. The end face of the upper second bevel gear 331 is fixedly mounted with an upper connecting rod 31. There is an upper three-link 33, and an upper four-link 34 is hinged to the door panel 61. The upper three-link 33 and the upper four-link 34 are hinged together. A lower gear 911 that meshes with a lower rack is rotatably connected below the upper gear 311 on the front side plate 1 and the rear side plate 2. A lower gear 911 is fixedly provided on the end face of the lower gear 911. A lower bevel gear 921 is rotatably connected below the upper bevel gear 322 on the first side plate 43. A lower second gear 922 is fixedly provided on the end face of the lower bevel gear 921. A lower second link is fixedly provided on the lower second gear 922. Rod 92, the next connecting rod 91 is hinged to the lower second connecting rod 92; a lower second bevel gear 931 that meshes with the lower bevel gear 921 is rotatably connected to the first convex plate 42 below the upper second bevel gear 331, and a lower third connecting rod 93 is fixedly provided on the end face of the lower second bevel gear 931; a lower third gear 941 is rotatably connected to the door panel 61 below the upper fourth connecting rod 34, and a lower fourth connecting rod 94 is fixedly provided on the end face of the lower third gear 941, and the lower third connecting rod 93 is hinged to the lower fourth connecting rod 94; when the telescopic plate assembly, side plate assembly, and folding plate assembly are extended... The upper link 31 and the upper second link 32 are collinear, and the upper third link 33 and the upper fourth link 34 are collinear; the lower link 91 and the lower second link 92 are collinear, and the lower third link 93 and the lower fourth link 94 are collinear; when the telescopic plate assembly, the side plate assembly, and the folding plate assembly are retracted, the upper link 31 and the upper second link 32 are in an intersecting position, and the upper third link 33 and the upper fourth link 34 are in an intersecting position; the lower link 91 and the lower second link 92 are in an intersecting position, and the lower third link 93 and the lower fourth link 94 are in an intersecting position. On the first side plate 43, a lower fourth gear 923 that meshes with the lower second gear 922 is rotatably connected near the lower gear 911. A first support rod 73 is fixedly provided on the end face of the lower fourth gear 923. On the door plate 61, a lower fifth gear 942 that meshes with the lower third gear 941 is rotatably connected near the lower third gear 941. A second support rod 72 is fixedly provided on the end face of the lower fifth gear 942.

[0042] When it is necessary to move the invention, in such a way... Figure 1 In the folded state shown, the present invention, which is equipped with a rotating wheel 71 on the front slide sleeve 14 and the rear slide rod 24, can be transported and transferred by using a transport vehicle to connect with the hook 111 on the front side plate 1.

[0043] After being transferred to the usage location, the transport vehicle is detached from the invention, and then the two first electric push rods 13 are retracted, causing the sliding frame 12 to move downwards. As the sliding frame 12 moves downwards, it causes the upper gear 311, which is rotatably connected to the front side plate 1 and the rear side plate 2 and meshes with the upper rack 121, to rotate, and the lower gear 911, which meshes with the lower rack 122, to rotate synchronously. When the upper gear 311 rotates, it causes the upper connecting rod 31 to rotate, which in turn causes the upper second connecting rod 32 to rotate. The upper second connecting rod 32 causes the upper bevel gear 322 to rotate, which in turn causes the upper third connecting rod 33 to rotate via the upper second bevel gear 331. The upper third connecting rod 33 then causes the upper fourth connecting rod 34 to rotate. When the lower gear 911 rotates, it causes the upper gear 311 to rotate, which in turn causes the upper gear 311 to rotate, which in turn causes the upper gear 311 to rotate, which in turn causes the upper gear 311 to rotate, which in turn causes the upper gear 9 ... The lower connecting rod 91 rotates, which in turn drives the lower second connecting rod 92 to rotate. The lower second connecting rod 92 drives the lower second gear 922 and the lower bevel gear 921 to rotate. The lower bevel gear 921 drives the lower third connecting rod 93 through the lower second bevel gear 931 to rotate. The lower third connecting rod 93 drives the lower fourth connecting rod 94 and the lower third gear 941 to rotate. When the upper connecting rod 31 and the upper second connecting rod 32 rotate, and when the lower connecting rod 91 and the lower second connecting rod 92 rotate, the intermediate plate 8 slides out of the first sliding groove 110 and the second sliding groove 43a. When the upper connecting rod 31 and the upper second connecting rod 32 are collinear, and when the lower connecting rod 91 and the lower second connecting rod 92 are collinear, the third stop block 81 abuts against the first stop block 172, and the fourth stop block 82 abuts against the second stop block 431. At the same time, the first plate 51 and the third plate 51a unfold, and the second plate 52 and the fourth plate 52a unfold. When the upper three-link 33 and upper four-link 34 rotate, and when the lower three-link 93 and lower four-link 94 rotate, the first convex plate 42 slides out of the third slide groove 613, the second convex plate 51b slides out of the fourth slide groove 52b, and the rear slide rod 24 slides out of the front slide sleeve 14, thereby completing the unfolding.

[0044] Furthermore, when the lower second gear 922 rotates, it drives the first support rod 73 vertically downwards via the lower fourth gear 923; when the lower third gear 941 rotates, it drives the second support rod 72 vertically downwards via the lower fifth gear 942. The folding plate assembly located above the front side panel 1 and the rear side panel 2 unfolds to form the top of the invention, and the folding plate assembly located below the front side panel 1 and the rear side panel 2 unfolds to form the bottom of the invention. Because a portion of the space between the lower folding plate assemblies utilizes the front sliding sleeve 14 and the rear sliding rod 24 as part of the floor, this allows for the storage of furniture (such as…) even when the invention is folded up. Figure 5 (As shown).

[0045] When the present invention needs to be moved, the furniture is first placed on top of the front sliding sleeve 14. After placement, the two first electric push rods 13 are simultaneously activated to extend, driving the sliding frame 12 to move upward. At this time, due to the upward lifting of the sliding frame 12, the upper gear 311, which is rotatably connected to the front side plate 1 and the rear side plate 2 and meshes with the upper rack 121, rotates in the opposite direction, and the lower gear 911, which meshes with the lower rack 122, rotates synchronously in the opposite direction. When the upper gear 311 rotates in the opposite direction, it drives the upper connecting rod 31 to rotate. The upper connecting rod 31 drives the upper second connecting rod 32 to rotate. The upper second connecting rod 32 drives the upper bevel gear 322 to rotate. The upper bevel gear 322, through the upper second bevel gear 33, rotates. 1. The upper three-link 33 rotates, and the upper three-link 33 rotates the upper four-link 34. When the lower gear 911 rotates, it drives the lower link 91 to rotate in the opposite direction. The lower link 91 drives the lower two-link 92 to rotate. The lower two-link 92 drives the lower two gears 922 and the lower bevel gear 921 to rotate. The lower bevel gear 921 drives the lower three-link 93 to rotate through the lower two bevel gear 931. The lower three-link 93 drives the lower four-link 94 and the lower three gears 941 to rotate. When the upper link 31 and the upper two-link 32 rotate, and when the lower link 91 and the lower two-link 92 rotate, the intermediate plate 8 enters the first slide groove 110 and the extension plate 112 enters the second slide groove 43a. At the same time, the first plate 51 and the third plate 51a fold, and the second plate 52 and the fourth plate 52a fold. When the upper three-link 33 and upper four-link 34 rotate, and when the lower three-link 93 and lower four-link 94 rotate, the first convex plate 42 slides into the third slide groove 613, the second convex plate 51b slides into the fourth slide groove 52b, and the rear slide rod 24 slides into the front slide sleeve 14, thereby completing the retraction. Additionally, when the lower second gear 922 rotates, it drives the first support rod 73 to rotate laterally via the lower fourth gear 923; when the lower third gear 941 rotates, it drives the second support rod 72 to rotate laterally via the lower fifth gear 942. Figure 1 When fully retracted as shown, the invention can be transported and transferred again using a trailer.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
