Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, and in particular to modular building steel structures. Background Technology

[0002] Steel structure construction is a new type of building system. Compared to traditional concrete buildings, steel structure buildings use steel plates or profiles instead of reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be factory-made and installed on-site, construction time is significantly reduced. The reusability of steel also greatly reduces construction waste, making it more environmentally friendly.

[0003] Temporary prefabricated houses are temporary buildings constructed using steel structures. As a type of temporary building, they are of high quality, inexpensive, movable, reusable, and stackable. However, when assembling traditional temporary prefabricated houses, the wall panels, supporting columns, roof panels, and floor panels are usually fixed by welding and bolts, which involves a large amount of work during installation. After use in the corresponding area, when the prefabricated house needs to be moved, it often needs to be moved as a whole, which is inconvenient. Disassembling and moving the prefabricated house is also very inconvenient, and the components of the prefabricated house may be damaged during the disassembly process, affecting its secondary use.

[0004] Therefore, this application provides a modular steel structure for building construction to solve the problems mentioned in the background art. Utility Model Content

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The modular steel structure provided by this utility model involves setting a base on the ground, with support columns adapted to be installed inside the base. The support columns have sliding grooves on their side walls, and wall panels slide from top to bottom into two adjacent support columns through the sliding grooves. After installation, the top plate is installed on the top of the support column and sleeved with the installation column, using a mortise and tenon structure for installation connection.

[0034] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] The present invention will be further explained below with reference to specific embodiments.

[0038] like Figures 1-12 As shown, the modular steel structure provided in this embodiment includes a base 1. The inner cavity of the base 1 is adapted to the bottom of the support column 2. A groove 3 is opened on the side wall of the support column 2. A wall panel 4 is adapted to be installed in the groove 3. The two end faces of the wall panel 4 are adapted to the two support columns 2. The groove 3 on the support column 2 is located at 1 / 3 of its outer side. The top face of the support column 2 and the wall panel 4 is adapted to the top plate 5. The top plate 5 is fitted onto the mounting column 6 at the top of the support column 2. This steel structure adopts a mortise and tenon structure. The support column 2 is placed directly in the base 1. The support column 2 achieves stability through its own weight. The bottom surface of the base 1 is larger than the bottom surface of the support column 2, increasing the contact area between the support column 2 and the ground and enhancing the stability of the support column 2. The wall panel 4 is slidably installed on the mounting column 6 from top to bottom through the groove 3. The mortise and tenon structure is used for connection, eliminating the need for welding or bolts for fixing, which greatly simplifies the installation process. The installation is efficient and the disassembly is convenient. At the same time, the disassembly will not cause damage to the corresponding components, thus facilitating disassembly and reuse.

[0039] like Figures 9-10 As shown, in this embodiment, the sliding groove 3 includes a first sliding groove 7 and a second sliding groove 8. The first sliding groove 7 and the second sliding groove 8 are respectively opened on two adjacent side walls of the support column 2 body. An installation column 6 is provided at the top of the support column 2 body, and the height of the installation column 6 is 8-10cm. The sliding groove 3 extends from the bottom end face of the support column 2 to the top end face of the installation column 6. With two sliding grooves 3 on the support column 2, the wall panel 4 can be slidably and fixedly installed with the support column 2 through the sliding grooves 3, which greatly simplifies the installation process. During installation, since the base 1 needs to be installed first, and then the support column 2 is placed in the base 1, the wall panel 4 is installed from top to bottom. The sliding groove 3 extends from the bottom end face of the support column 2 to the top end face of the installation column 6.

[0040] like Figures 2-12As shown, the supporting columns 2 are the first column 9, the second column 10, the third column 11, and the fourth column 12. The wall panel 4 includes the first panel 13, the second panel 14, the third panel 15, and the fourth panel 16. The height of the wall panel 4 is equal to the height of the supporting columns 2. The first panel 13 is fitted into the first groove 7 of the fourth column 12 and the second groove 8 of the first column 9. The second panel 14 is fitted into the first groove 7 of the first column 9 and the second groove 8 of the second column 10. The third panel 15 is fitted into the first groove 7 of the second column 10 and the second groove 8 of the third column 11. The fourth panel 16 is fitted into the first groove 7 of the third column 11 and the second groove 8 of the fourth column 12. A window 17 is provided on the first panel 13, and a door 18 is provided on one side of the window 17. Windows 17 are also provided on the second panel 14 and the fourth panel 16. The opening directions of the grooves 3 on opposite sides of two adjacent supporting columns 2 are opposite, while the other opening direction is the same. Figure 2 For example, on the opposite surfaces of the first column 9 and the second column 10 are the first sliding groove 7 and the second sliding groove 8, respectively. The opening directions of the first sliding groove 7 of the first column 9 and the second sliding groove 8 of the second column 10 are opposite, while the opening directions of the second sliding groove 8 of the first column 9 and the first sliding groove 7 of the second column 10 are both towards the direction of the third plate 15. Four bases 1 and four supporting columns 2 are set at the four corners. Each base 1 is not connected to the others, allowing the customer to choose the length and width of the self-built house according to their needs. Only the distance between the bases 1 needs to be adjusted, and the corresponding wall panel 4 and roof panel 5 can be selected based on the adjusted distance.

[0041] Furthermore, the four corner support columns 2 have identical structures, differing only in their placement angle and position. For ease of description, the support columns 2 are referred to as the first column 9, the second column 10, the third column 11, and the fourth column 12. To better describe the relative positional relationship, the wall panel 4 is divided into the first panel 13, the second panel 14, the third panel 15, and the fourth panel 16. The thickness of the wall panel 4 is the same as the width of the groove 3 provided on the support column 2 body. The groove 3 is usually located at the center, but in this embodiment, to enhance the structural strength of the support column 2, the groove 3 is located at 1 / 3 of its outer side, increasing the distance between the two grooves 3, that is, thickening the remaining structure between the two grooves 3 to enhance the structural strength of the support column 2.

[0042] like Figures 5-10As shown, mounting grooves 19 adapted to mounting posts 6 are provided at the four corners below the top plate 5. Two stabilizing protrusions 20 are provided in the mounting grooves 19, corresponding to the positions of the first sliding groove 7 and the second sliding groove 8 respectively. The depth of the mounting grooves 19, the height of the stabilizing protrusions 20 and the height of the four sides of the top plate 5 are equal. The mounting grooves 19 and the mounting posts 6 are interference-fitted by the stabilizing protrusions 20. The side wall of the base 1 is provided with notches 21 adapted to sliding grooves 3. The depth of the notches 21 is 20-30cm. An extension plate 22 is provided extending outward from the edge of the notches 21. The length of the extension plate 22 is 20-30cm. Preferably, the length of the extension plate 22 is 20cm. The height of the base 1 is 30-40cm. Preferably, the height of the base 1 is 30cm. The mounting groove 19 and the mounting column 6 cooperate to fix the top plate 5 above the support column 2. To increase stability, a stabilizing protrusion 20 is also provided in the mounting groove 19. Since the support column 2 is provided with a sliding groove 3, the side wall needs to slide into the support column 2 from above through the sliding groove 3. Therefore, the mounting column 6 on the support column 2 will also have a notch corresponding to the position and size of the sliding groove 3. The stabilizing protrusion 20 can cooperate with the mounting column 6 with the notch to realize the cooperation between the support column 2 and the top plate 5. The mounting groove 19 and the mounting column 6 are interference-fitted through the stabilizing protrusion 20. The interference of the steel structure is selected in the range of 0.075-0.125mm, preferably 0.1mm.

[0043] The wall panel 4 is slidably installed into the groove 3 of the support column 2. The base 1 is located below the support column 2, and the inner cavity of the base 1 is adapted to the bottom of the support column 2. The base 1 is provided with a notch 21 that is adapted to the groove 3. The depth of the notch 21 is 20-30cm, preferably 20cm. During the process of sliding the wall panel 4 into the groove 3, the lower part of the wall panel 4 will slide into the notch 21 and fit against the extension plate 22 extending outward along the edge of the notch 21. When the wall panel 4 is installed into the groove 3 and the notch 21, There is a 10cm height difference between the bottom surface of the wall panel 4 and the bottom surface of the base 1. The distance between the wall panel 4 and the ground can be adjusted by adjusting the embedment depth of the base 1 according to the thickness of the precast floor slab in the room. The sliding groove 3, the notch groove 21, and the extension plate 22 have contact areas with the wall panel 4. The combination of the sliding groove 3 and the notch groove 21 facilitates the installation of the wall panel 4. At the same time, the combination of the sliding groove 3, the notch groove 21, and the extension plate 22 increases the horizontal contact area of ​​the wall panel 4 and increases the stability of the wall panel 4 after installation.

[0044] The working principle of the modular steel structure of this utility model:

[0045] Choose a suitable ground surface at the location where the prefabricated house needs to be built, and construct four corresponding pits that fit the base 1 to place the base 1. Select corresponding wall panels 4 and top panels 5 according to the distance between the base 1s, and select corresponding floor panels to be placed inside the prefabricated house. Alternatively, tiles or other floor decorations can be laid directly on the selected ground. After selection, place the base 1 into the pit and fix it. Then, place the four support columns 2 into the base 1 according to the above position and angle relationship. After placement, slide the four wall panels 4 from top to bottom along the grooves 3 of the support columns 2 so that the upper surface of the wall panels 4 is flush with the upper surface of the support columns 2. Then, install the top panel 5 on the top of the support columns 2, ensuring that the mounting grooves 19 at the four corners of the top panel 5 are interference-fitted with the mounting columns 6 at the top of the support columns 2 to complete the assembly of the prefabricated house. Disassembly is simply a matter of reversing the above steps, which will not be elaborated here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
