Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to an assembled light steel structure. Background Art

[0002] Prefabricated building steel structure is an innovative and environmentally friendly form of building structure. It prefabricates steel structure components in the factory and then transports these components to the construction site for splicing and installation. This construction method has significant advantages such as saving materials, convenient construction and reducing construction costs. During the construction of the building steel structure, on-site assembly is adopted to make construction more convenient.

[0003] When assembling steel structures, many of them are directly connected by bolts between the beams and columns. Therefore, it is necessary to pre-open holes in the beams and columns before assembling the steel structure. During installation, the holes opened in the beams need to be aligned and overlapped with the holes opened in the columns, and bolts are passed through the two holes to implement the installation between the beams and columns. However, when aligning and overlapping the two holes, a crane is required to lift the beam column first, and then slowly align and overlap the holes opened in the beam with the holes opened in the columns. Due to the small diameter of the holes, it takes a long time to align and overlap the two holes, which wastes a lot of time and reduces the installation efficiency of the assembled steel structure beams.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 5The present invention provides a technical solution: an assembled light steel structure, including a column 1, a mounting bracket 2 is provided on the right side of the column 1, a crossbeam 3 is provided on the right part of the mounting bracket 2, and an auxiliary alignment component 4 is provided on the left part of the crossbeam 3, and the auxiliary alignment component 4 includes a sliding groove 41 opened on the left side of the interior of the crossbeam 3, a fixed plate 42 is fixedly connected to the interior of the sliding groove 41, a lifting rod 43 is slidably connected to the interior of the fixed plate 42, the outer wall of the lifting rod 43 is located below the fixed plate 42 and is fixedly connected to a movable plate 44, a first spring 45 is fixedly connected between the movable plate 44 and the fixed plate 42, and a thread is opened on the top of the lifting rod 43, and a bearing 46 is provided inside the sliding groove 41 above the fixed plate 42, the outer ring of the bearing 46 is fixedly connected to the sliding groove 41, and the inner ring of the bearing 46 is fixedly connected to a sleeve rod 47, and the thread opened on the top of the lifting rod 43 is fixed to the sleeve The rod 47 is threadedly connected, and the top of the sleeve rod 47 is fixedly connected to a gear 48. The auxiliary alignment assembly 4 also includes a rack 410 slidably connected to the top of the beam 3. The outer side of the gear 48 meshes with the rack 410. An insertion portion 49 is provided on the left side of the rack 410. A clamping assembly 5 is provided at the corresponding position of the insertion portion 49 on the right side of the mounting bracket 2. The clamping assembly 5 includes a fixing seat 51 fixedly connected to the right side of the mounting bracket 2. A card slot 52 is provided on the right part of the fixing seat 51. The mounting bracket 2 includes a connecting plate 21 that is detachably connected to the right side of the column 1. The right side of the connecting plate 21 is fixedly connected to a cross plate 22. The top of the cross plate 22 and the connecting plate 21 are jointly fixedly connected to a limiting plate 23. The front and rear ends of the left part of the beam 3 are detachably connected to a blocking plate 10. The top rear end of the beam 3 is fixedly connected to a bent frame 11, and the top of the limiting plate 23 is tilted.

[0021] When the cam 22 is in the upright position, the cam 22 is in the upright position, and ... The first spring 45 is compressed, and the lifting rod 43 moves upward. Under the action of the threaded connection, the sleeve rod 47 rotates with the gear 48. Under the action of the gear 48 meshing with the rack 410, the gear 48 rotates, and the rack 410 can be moved to the left, so that the left part of the insertion part 49 is inserted into the slot 52 opened in the fixing seat 51. This can limit the position of the insertion part 49 and the crossbeam 3 and avoid the crossbeam 3 from being limited. Under the cooperation of the auxiliary alignment component 4, the clamping component 5, the limiting plate 23 and the blocking plate 10, it is convenient to limit the crossbeam 3 before installing the screw to fix the crossbeam 3, so that the hole opened on the crossbeam 3 is aligned with the hole opened on the cross plate 22. At this time, the crossbeam 3 and the cross plate 22 can be fixed by bolts, thereby improving the efficiency of installing the crossbeam 3.

[0022] The top of the limit plate 23 is tilted. Under the effect of the top tilt design, it is convenient for the two blocking plates 10 to be located on both sides of the limit plate 23 when they descend. The bearing 46 is a mature existing technology, and the outer ring of the bearing 46 is fixedly connected to the inside of the sliding groove 41.

[0023] It should be noted that the pitch of the thread opened at the top of the lifting rod 43 is set to be larger. Such a design is conducive to reducing the friction between the thread of the lifting rod 43 and the sleeve rod 47, making it easier for the sleeve rod 47 to rotate when the lifting rod 43 is lifted. The threaded connection method is similar to the connection method between the screw part and the flying saucer part of a hand-pushed flying saucer.

[0024] The bottom of the bent frame 11 fits against the top surface of the rack 410 , which helps to enhance the structural stability of the rack 410 and the insertion portion 49 .

[0025] Specifically, such as Figures 2 to 7As shown, a movable slot 53 is provided on the top of the card slot 52 on the right side of the fixed seat 51, and the insertion portion 49 includes a sleeve plate 491 fixedly connected to the left side of the rack 410, and the left part of the sleeve plate 491 is slidably connected to a through plate 492, and a second spring 493 is fixedly connected between the right side of the through plate 492 and the sleeve plate 491.

[0026] By adopting the above technical solution, before the bottom of the beam 3 fits the horizontal plate 22, the left side of the through plate 492 contacts the fixed seat 51. As the beam 3 continues to move downward, the rack 410 moves the through plate 492 and the sleeve plate 491 to the left. At this time, under the limiting action of the fixed seat 51, relative sliding occurs between the through plate 492 and the sleeve plate 491. At this time, the second spring 493 is compressed and moves downward with the beam 3, causing the left part of the through plate 492 to slide up and down inside the movable groove 53.

[0027] When the through plate 492 reaches the slot 52 , the through plate 492 moves to the left under the elastic force of the second spring 493 . At this time, the through plate 492 is inserted into the slot 52 , thereby facilitating the positioning of the crossbeam 3 .

[0028] Furthermore, such a design enables the through plate 492 to be inserted deeper into the slot 52 , thereby improving the limiting effect on the crossbeam 3 .

[0029] Specifically, such as Figures 2 to 5 As shown, an obstruction assembly 6 is provided at the bottom of the lifting rod 43, and the obstruction assembly 6 includes a round rod 61 fixedly connected to the bottom of the lifting rod 43, and a swing plate 62 is rotatably connected between the front and rear ends of the outer wall of the round rod 61, and a torsion spring 63 is fixedly connected between the round rod 61 and the swing plate 62. The top of the horizontal plate 22 is located below the swing plate 62 and is provided with an insertion slot 16.

[0030] By adopting the above technical solution, under the elastic force of the torsion spring 63 itself, the lifting rod 43 and the swing plate 62 are in a vertical state. When the cross beam 3 is hoisted and placed downward, the swing plate 62 at the bottom of the lifting rod 43 first contacts the top of the cross plate 22. If the cross beam 3 is in an inclined state when placed downward, the swing plate 62 is also in an inclined state when contacting the cross plate 22. The inclined swing plate 62 moves downward with the cross beam 3, so that the angle between the swing plate 62 and the lifting rod 43 changes. Under the elastic force of the torsion spring 63, it is beneficial to apply elastic force to the cross beam 3 horizontally, so that the cross beam 3 is in a relatively horizontal state when it descends, thereby ensuring that the insertion portion 49 is aligned with the card slot 52, thereby improving the efficiency of the insertion portion 49 inserting the card slot 52. This design further improves the efficiency of the installation of the cross beam 3. After installation, the swing plate 62 is hidden in the slot 16.

[0031] Specifically, such as Figures 2 to 7As shown, a limiting component 7 is provided inside the fixing seat 51, and the limiting component 7 includes a small plate 71 slidably connected to the inside of the card slot 52, and a medium bag 72 is fixedly connected to the left side of the small plate 71. The limiting component 7 also includes a sleeve 73 fixedly connected to the inside of the fixing seat 51, and a piston plate 74 is movably connected inside the sleeve 73. A blocking rod 75 is fixedly connected to the bottom of the piston plate 74, and a third spring 76 is fixedly connected between the top of the piston plate 74 and the sleeve 73. A catheter 77 is fixedly inserted between the medium bag 72 and the sleeve 73, and the elastic force of the second spring 493 is greater than the elastic force of the third spring 76.

[0032] The upper part of the fixing seat 51 near the slot 52 is spliced ​​with other parts of the fixing seat 51 during the production of the device to form a complete fixing seat 51, so that the sleeve 73, piston plate 74, blocking rod 75 and other components can be installed inside the fixing seat 51 when the device is produced.

[0033] By adopting the above technical solution, the size of the slot 52 is larger than that of the through plate 492. In the initial state, under the elastic force of the third spring 76, the blocking rod 75 does not extend into the interior of the slot 52. When the through plate 492 is inserted into the slot 52, under the elastic force of the second spring 493, the through plate 492 is inserted into the interior of the slot 52. At this time, since the elastic force of the second spring 493 is greater than the elastic force of the third spring 76, the through plate 492 squeezes the small plate 71, causing the small plate 71 to move to the left, thereby squeezing the medium bag 72, so that the medium inside the medium bag 72 enters the interior of the conduit 77 and then enters the interior of the sleeve 73. In this way, the medium squeezes the piston plate 74, causing the piston plate 74 to move downward with the blocking rod 75. This design makes it easier for the blocking rod 75 to squeeze the top of the through plate 492, thereby improving the effect of limiting the through plate 492, thereby improving the effect of limiting the cross beam 3, and further facilitating the alignment of the holes opened on the cross beam 3 with the holes opened on the cross plate 22, thereby improving installation efficiency.

[0034] Specifically, such as Figure 6 and Figure 7 As shown, the sleeve 73 and the blocking rod 75 are both arranged at an angle.

[0035] By adopting the above technical solution, the blocking rod 75 is tilted, so that even if the left side of the beam 3 is tilted to squeeze the blocking rod 75 upward, the applied force does not remain parallel to the blocking rod 75 due to the tilted design of the blocking rod 75, thereby reducing the effect of the blocking rod 75 being squeezed open. Such a design is conducive to improving the limiting effect of the blocking rod 75 on the through plate 492, thereby improving the limiting effect on the beam 3.

[0036] Specifically, such as Figures 1 to 3 and Figure 8As shown, both top and bottom ends of the connecting plate 21 are fixedly connected to the mounting frame 8, the interior of the mounting frame 8 is fixedly connected to a small shaft 9, the outer wall of the small shaft 9 is movably connected to a left rod 12, the right side of the left rod 12 is rotatably connected to a rotating rod 13, the right side of the interior of the rotating rod 13 is threaded, and the right side of the interior of the rotating rod 13 is threadedly connected to a hook rod 14, and both top and bottom ends of the beam 3 are detachably connected to a hook frame 15, and the right side of the hook rod 14 is buckled into the interior of the hook frame 15.

[0037] By adopting the above technical solution, the opening at the connection between the left rod 12 and the small shaft 9 is larger than the diameter of the small shaft 9. Such a design is conducive to the swinging of the left rod 12, the rotating rod 13 and the hook rod 14. After the cross beam 3 is installed by bolts, the hook frame 15 is installed by bolts, and then the left rod 12 is swung and rotated so that the hook of the hook rod 14 is inserted into the interior of the hook frame 15. Then, by manually rotating the rotating rod 13, the hook rod 14 is moved under the action of the threaded connection, so that the hook rod 14 is tightened at the hook frame 15. Such a design is conducive to improving the stability of the mechanism when the hook frame 15 is installed.

[0038] When the cam 22 is lifted up, the cam 23 is lifted up and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position, and the cam 23 is in the upright position The inner sliding of the fixed plate 42 causes the movable plate 44 to move upward with the fixed plate 42. At this time, the first spring 45 is compressed, and due to the upward movement of the lifting rod 43, the sleeve rod 47 rotates with the gear 48 under the action of the threaded connection. Under the action of the gear 48 meshing with the rack 410, when the gear 48 rotates, the rack 410 can be moved in the direction of the left side, thereby facilitating the insertion of the left part of the insertion portion 49 into the slot 52 opened in the fixed seat 51. This can limit the position of the insertion portion 49 and the crossbeam 3 and avoid the crossbeam 3 from being limited. Under the cooperation of the auxiliary alignment component 4, the clamping component 5, the limit plate 23 and the blocking plate 10, it is convenient to limit the crossbeam 3 before installing the screw to fix the crossbeam 3, thereby facilitating the alignment of the holes opened on the crossbeam 3 with the holes opened on the cross plate 22. At this time, the crossbeam 3 and the cross plate 22 can be fixed by bolts, thereby improving the efficiency of installing the crossbeam 3.

[0039] When the through plate 492 reaches the part of the slot 52, under the action of the elastic force of the second spring 493, the through plate 492 moves to the left direction. At this time, the through plate 492 is inserted into the interior of the slot 52, which is conducive to limiting the crossbeam 3. In addition, such a design allows the through plate 492 to be inserted deeper into the slot 52, thereby improving the limiting effect on the crossbeam 3.

[0040] Under the elastic force of the torsion spring 63 itself, the lifting rod 43 and the swing plate 62 are in a vertical state. When the beam 3 is hoisted and placed downward, the swing plate 62 at the bottom of the lifting rod 43 first contacts the top of the cross plate 22. If the cross beam 3 is in an inclined state when placed downward, the swing plate 62 is also in an inclined state when contacting the cross plate 22. The inclined swing plate 62 moves downward with the cross beam 3, so that the angle between the swing plate 62 and the lifting rod 43 changes. Under the elastic force of the torsion spring 63, it is beneficial to apply elastic force to the horizontal beam 3, so that the cross beam 3 is in a relatively horizontal state when it descends, thereby ensuring that the insertion portion 49 is aligned with the slot 52, thereby improving the efficiency of the insertion portion 49 inserting the slot 52. Such a design further improves the efficiency of the installation of the cross beam 3.

[0041] When the through plate 492 is inserted into the slot 52, under the elastic force of the second spring 493, the through plate 492 is inserted into the inside of the slot 52. At this time, since the second spring 493 is greater than the elastic force of the third spring 76, the through plate 492 squeezes the small plate 71, causing the small plate 71 to move to the left, thereby squeezing the medium bag 72, so that the medium inside the medium bag 72 enters the inside of the conduit 77 and then enters the inside of the sleeve 73. In this way, the medium squeezes the piston plate 74, causing the piston plate 74 to move downward with the blocking rod 75. This design makes it easier for the blocking rod 75 to squeeze the top of the through plate 492, thereby improving the effect of limiting the through plate 492, thereby improving the effect of limiting the cross beam 3, and further facilitating the alignment of the holes opened on the cross beam 3 with the holes opened on the cross plate 22, thereby improving the installation efficiency.
