Description

Technical Field

[0002] Light steel structure houses are widely used in temporary buildings, modular housing and other fields due to their advantages such as convenient construction, high strength, environmental protection and energy saving. Traditional light steel house frames are mainly composed of columns, transverse beams and connectors, which are fixed together by bolts or welding. For example, patent (CN111042340B) discloses a steel structure house frame, which realizes the rapid assembly and disassembly of the entire house frame by setting modular support beams and easy-to-disassemble top beams, perfectly replacing traditional bolt connections and welding connections, making the installation and disassembly process of the entire house frame easier and more convenient; When using the above technology, we found the following technical problems in the existing technology: although the support angle of the beam can be adjusted, the adjustment will cause the distance between the two bases to change. Its modular beam body relies on the rigidity of the material itself to resist the load. During long-term use, the middle part of the beam is prone to bending and deformation due to stress concentration, affecting the structural stability. For this reason, we designed a light steel structure house frame to provide another technical solution to the above technical problems. Summary of the Invention

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example 1:

[0024] See also Figure 1-10 , a light steel structure house frame, comprising a plurality of house steel structure components, wherein an adjustment mechanism for adjusting the distance between two adjacent house steel structure components is provided between each two adjacent house steel structure components; The house steel structure assembly consists of two vertical I-steel columns 1 and a top crossbeam assembly, and the top crossbeam assembly is erected on the top of the two vertical I-steel columns 1; The top crossbeam assembly includes two transverse rotating members 5, which are rotatably connected by a pin. A transverse connecting pipe 4 is provided at one end of the transverse rotating member 5. A transverse steel beam 2 is fixed to the internal bolts of the transverse connecting pipe 4. One end of the transverse steel beam 2 is rotatably connected to a vertical mounting block 3 via a pin. The bottom of the vertical mounting block 3 is fixed to the vertical I-beam column 1 by bolts. A rotation mechanism for driving the transverse steel beam 2 to rotate is provided on the inner side of the vertical I-beam column 1; A support mechanism for supporting the horizontal rotating member 5 is also provided between the two vertical I-steel columns 1; The rotating mechanism includes a first vertical mounting plate 7, the first vertical mounting plate 7 is close to one side of the vertical I-steel column 1 and is bolted to the vertical I-steel column 1, the top of the first vertical mounting plate 7 away from the vertical I-steel column 1 and the top are fixed with a first rectangular mounting block 8, the interior of one of the first rectangular mounting blocks 8 is rotatably connected to a first hand wheel 9, the top of the first hand wheel 9 is fixed to a first vertical threaded rod 10, the outer side of the first vertical threaded rod 10 is threadedly connected to a first vertical slider 12, the top of the first vertical threaded rod 10 is rotatably connected to another first rectangular mounting block 8, the side of the first vertical slider 12 away from the vertical I-steel column 1 is rotatably connected to an oblique support column 13 through a pin shaft, and the top of the oblique support column 13 is rotatably connected to the transverse steel beam 2 through a pin shaft; A vertical polished rod 11 is fixed at both ends between the two first rectangular mounting blocks 8. The vertical polished rod 11 passes through the interior of the first vertical slider 12 and is slidably connected to the first vertical slider 12. Through the arrangement of the vertical polished rod 11, the first vertical slider 12 can slide vertically on the outside of the vertical polished rod 11, thereby enabling the vertical polished rod 11 to guide the vertical lifting trajectory of the first vertical slider 12; The rotation mechanism further includes a transverse sliding plate 15, which is slidably connected to the interior of the transverse rotating member 5. A transverse sliding post 14 is fixed to one end of the transverse sliding plate 15 close to the transverse connecting tube 4. The transverse sliding post 14 passes through the interior of the transverse rotating member 5 and is slidably connected to the transverse rotating member 5. The transverse sliding post 14 is fixedly connected to the transverse connecting tube 4. A rectangular slot is provided inside the transverse rotating member 5. The transverse sliding plate 15 is located inside the rectangular slot and is slidably connected to the transverse rotating member 5 via the rectangular slot. The rectangular slot allows the transverse sliding plate 15 to slide transversely inside the transverse rotating member 5, thereby allowing the transverse sliding post 14 to slide inside the transverse rotating member 5. Here, when the support angle of the transverse steel beam 2 needs to be adjusted, the operation of the first hand wheel 9 enables the first vertical threaded rod 10 to rotate, and the rotation of the first vertical threaded rod 10 enables the first vertical slider 12 to slide vertically on the outside of the vertical light rod 11. The vertical sliding of the first vertical slider 12 enables the transverse steel beam 2 to rotate inside the vertical mounting block 3 through the oblique support column 13, thereby adjusting the support angle of the transverse steel beam 2, and when the transverse steel beam 2 rotates, the transverse sliding plate 15 can slide inside the transverse rotating member 5, thereby enabling the transverse sliding column 14 to slide inside the transverse rotating member 5, thereby adjusting the support angle of the transverse steel beam 2 while the distance between the two vertical I-beam columns 1 remains unchanged.

[0025] The support mechanism includes a V-shaped support member 6, a V-shaped support member 6 is fixed to the bottom of the transverse rotating member 5, a first circular support roller 17 is rotatably connected to the bottom of the V-shaped support member 6, a metal support cable 16 is provided at the bottom of the first circular support roller 17, and a second circular support roller 18 is rotatably connected to both ends of the vertical mounting block 3, the metal support cable 16 is located on the top of the second circular support roller 18, a support disc 20 is fixed to the bottom of the metal support cable 16, a plurality of circular counterweights 21 are provided inside the support disc 20, and a third circular support roller 19 is further provided on the inner side of the metal support cable 16, the third circular support roller 19 is close to one side of the vertical I-beam column 1 and is fixedly connected to the vertical I-beam column 1; An active force dispersion system is constructed through "V-shaped support member + metal support cable + circular counterweight block": The V-shaped support member 6 is fixed to the bottom of the transverse rotating member 5 and transmits the load to the metal support cable 16 through the first circular support roller 17; The metal support cable 16 is tensioned by the second and third circular support rollers, and the support plate 20 and the circular counterweight 21 at the bottom provide reverse tension, forming a "top push + bottom pull" balanced force structure, distributing the concentrated load of the beam 2 to the vertical I-beam columns 1 on both sides.

[0026] The third circular support roller 19 is fixed to the inside of the vertical I-beam column 1 (near the bottom of the transverse rotating member 5) and is directly and rigidly connected to the vertical I-beam column 1 (e.g., welded or bolted). Simultaneously, the inside of the metal support cable 16 is in contact with the outer surface of the third circular support roller 19, forming a rigid transmission chain of "metal support cable-roller-column".

[0027] Force transmission path: the dispersion process from the horizontal rotating member 5 to the vertical I-beam column 1; Step 1: The load is transferred from the transverse rotating member 5 to the metal supporting cable 16; the metal supporting cable 16 is a braided cable.

[0028] After the transverse rotating member 5 bears the load of the transverse steel beam 2 (such as the weight of the roof and its own gravity), the force is transmitted to the first circular support roller 17 through the V-shaped support member 6 at the bottom. The first circular support roller 17 generates downward pressure (i.e., "upward" force) on the metal support cable 16, causing the metal support cable 16 to form a downward bending trend here.

[0029] Step 2: The third circular support roller 19 provides "lateral support and force diversion" to the metal support belt 16; The metal support cable 16 is a flexible belt. Under the pressure of the first circular support roller 17, it will extend to both sides. However, because the third circular support roller 19 is located on the inner side of the metal support cable 16 and is fixed to the vertical I-beam column 1, it forms a "lateral blockage" for the metal support cable 16. The extension force of the metal support cable 16 is offset by the third circular support roller 19, and the pressure is converted into tension along the direction of the metal support cable through the roller body; The third circular support roller 19 transmits the tension of the metal support cable 16 to the vertical I-steel column 1 through its rigid connection with the vertical I-steel column, thereby realizing the transformation of "load from the metal support cable to the column".

[0030] Step 3: The vertical I-beam columns on both sides bear the load together; Since the metal support cables 16 are symmetrically distributed (third circular support rollers 19 and vertical I-beam columns 1 are provided on both sides), the concentrated load of the transverse rotating member 5 is divided into two forces through the metal support cables, and is transmitted to the corresponding vertical I-beam columns through the third circular support rollers 19 on both sides respectively, and finally is jointly borne by the vertical I-beam columns on both sides, avoiding the load concentration on a single point.

[0031] Core function: change the direction of force and provide a rigid support point; The key function of the third circular support roller 19 is to convert the vertical force of the metal support cable into a lateral force to the vertical I-beam column 1; Without the third circular support roller 19, the metal support cable 16 will sag directly under the load and will not be able to transmit the force to the vertical I-beam column. It can only be passively tensioned by the gravity of the counterweight block and will not be able to actively distribute the load. The third circular support roller 19, through its own rigidity and position design, becomes the "force turning hub" between the metal support cable 16 and the vertical I-beam column 1, which not only restrains the deformation of the metal support cable, but also stably transfers the dispersed tension to the column, thus completing the whole process of "concentrated load → dispersed transfer → column bearing".

[0032] A rectangular through-slot is provided inside the oblique support column 13. The metal support cable 16 passes through the oblique support column 13 and is located inside the rectangular through-slot. The rectangular through-slot enables the metal support cable 16 to move inside the oblique support column 13, thereby enabling the metal support cable 16 to support the transverse rotating member 5. Here, by setting up the metal support cable 16, the two transverse rotating parts 5 can be supported to prevent the connection between the two transverse steel beams 2 from collapsing due to gravity, thereby improving the supporting performance of the transverse steel beam 2, and by adjusting the number of circular counterweights 21, the supporting efficiency of the metal support cable 16 for the two transverse rotating parts 5 can be adjusted.

[0033] The adjusting mechanism includes two second vertical mounting plates 22, which are respectively fixed to the inner side bolts of the two vertical I-beam columns 1. Second rectangular mounting blocks 23 are fixed to the top and bottom of the second vertical mounting plates 22. A second hand wheel 24 is rotatably connected to the interior of one of the second rectangular mounting blocks 23. A second vertical threaded rod 25 is fixed to the top of the second hand wheel 24. A third vertical threaded rod 26 is fixed to the top of the second vertical threaded rod 25. The second vertical threaded rod 25 and the third vertical threaded rod 26 have opposite thread rotation directions. The outer sides of the second vertical threaded rod 25 and the third vertical threaded rod 26 are both threadedly connected to a second vertical slider 27. One end of the second vertical slider 27 is rotatably connected to an oblique rotating rod 28. One end of the oblique rotating rod 28 is rotatably connected to a vertical connection 29 through a pin shaft. A dovetail slider is slidably connected to the interior of the second vertical slider 27, and the dovetail slider is fixedly connected to the second vertical mounting plate 22. The dovetail slider is configured so that the second vertical slider 27 can be slidably connected to the outside of the dovetail slider. The movement of the second vertical slider 27 enables the vertical connection 29 to move via the oblique rotating rod 28. The joint between the second vertical threaded rod 25 and the third vertical threaded rod 26 is rotatably connected to a support plate through a bearing. The support plate is close to one end of the second vertical mounting plate 22 and is fixedly connected to the second vertical mounting plate 22, thereby making the connection between the second vertical threaded rod 25 and the third vertical threaded rod 26 more stable and preventing bending between the second vertical threaded rod 25 and the third vertical threaded rod 26, so as to facilitate the synchronous rotation of the second vertical threaded rod 25 and the third vertical threaded rod 26; Here, when it is necessary to adjust the spacing between the two steel structure components of the house, by rotating the second hand wheel 24, the rotation of the second hand wheel 24 causes the second vertical threaded rod 25 and the third vertical threaded rod 26 to rotate, and the rotation of the second vertical threaded rod 25 and the third vertical threaded rod 26 enables the second vertical slider 27 to slide vertically on the outside of the dovetail slider. The vertical lifting of the second vertical slider 27 is achieved through the oblique rotating rod 28, so that the vertical connection 29 can be moved, thereby enabling the spacing between the two steel structure components of the house to be adjusted to meet the installation requirements of different spacings.

[0034] Working principle: When the support angle of the transverse steel beam 2 needs to be adjusted, the operation of the first hand wheel 9 enables the first vertical threaded rod 10 to rotate, and the rotation of the first vertical threaded rod 10 enables the first vertical slider 12 to slide vertically on the outside of the vertical polished rod 11. The vertical sliding of the first vertical slider 12 enables the transverse steel beam 2 to rotate inside the vertical mounting block 3 through the oblique support column 13, thereby adjusting the support angle of the transverse steel beam 2. When the transverse steel beam 2 rotates, the transverse sliding plate 15 can slide inside the transverse rotating member 5, thereby enabling the transverse sliding column 14 to slide inside the transverse rotating member 5, thereby adjusting the support angle of the transverse steel beam 2 while the distance between the two vertical I-beam columns 1 remains unchanged. The metal support straps 16 are provided to support the two transverse rotating members 5, thereby preventing the connection between the two transverse steel beams 2 from collapsing due to gravity, thereby improving the supporting performance of the transverse steel beams 2. Furthermore, the supporting efficiency of the metal support straps 16 for the two transverse rotating members 5 can be adjusted by adjusting the number of circular counterweights 21. When it is necessary to adjust the spacing between the two steel structure components of the house, the second hand wheel 24 is rotated. The rotation of the second hand wheel 24 causes the second vertical threaded rod 25 and the third vertical threaded rod 26 to rotate. The rotation of the second vertical threaded rod 25 and the third vertical threaded rod 26 enables the second vertical slider 27 to slide vertically on the outside of the dovetail slider. The vertical lifting of the second vertical slider 27 is achieved through the oblique rotating rod 28, so that the vertical connection 29 can be moved, thereby enabling the spacing between the two steel structure components of the house to be adjusted to meet the installation requirements of different spacings.

[0035] Example 2, based on Example 1, this example further discloses the following contents: Figure 11 As shown, when the V-shaped support member 6 rises and makes the middle section of the metal support cable 16 and the two transverse steel beams 2 form an isosceles triangle and the V-shaped support member 6 continues to rise, in order to avoid contact between the oblique support column 13 and the metal support cable 16, an L-shaped support arm 60 is fixedly connected to any one of the V-shaped support members 6, and the free end of the L-shaped support arm 60 extends downward from the side of the metal support cable 16, and a contact roller body 61 is provided at the free end of the L-shaped support arm 60 on the lower surface of the metal support cable 16. When the above-mentioned adjustment action occurs, the contact roller body 61 at this time can wrap the metal support cable 16 and move upward together, thereby preventing the metal support cable 16 from contacting the oblique support column 13.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
