Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly to a prefabricated light steel structure. Background Art

[0002] The prefabricated building steel structure is an innovative and environmentally friendly building structure form. It prefabricates steel structure components in a factory and then transports these components to the construction site for splicing and installation. This building method has significant advantages such as material saving, convenient construction, and reduced construction costs. During the construction of building steel structures, the on-site assembly method makes the construction more convenient.

[0003] When assembling the steel structure, in many cases, the cross beam and the column structure are directly fixed and connected with bolts. Therefore, it is necessary to pre-drill holes in the cross beam and the column before assembling the steel structure. During installation, the holes drilled in the cross beam need to be aligned and overlapped with the holes drilled in the column, and bolts are passed through the two holes to install the cross beam and the column. However, when aligning and overlapping the two holes, a crane is required to first lift the beam and column, and then slowly align the holes drilled in the cross beam with the holes drilled in the column. Since the diameter of the holes is small, it takes a long time to align and overlap the two holes, thus wasting a lot of time and reducing the installation efficiency of the cross beam of the prefabricated steel structure.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 5, the present invention provides a technical solution: a prefabricated light steel structure, including a column 1. A mounting bracket 2 is arranged on the right side of the column 1. A cross beam 3 is arranged on the right part of the mounting bracket 2. An auxiliary alignment component 4 is arranged on the left part of the cross beam 3. The auxiliary alignment component 4 includes a sliding groove 41 opened on the left side inside the cross beam 3. A fixed disk 42 is fixedly connected inside the sliding groove 41. A lifting rod 43 is slidably connected inside the fixed disk 42. A moving disk 44 is fixedly connected to the outer wall of the lifting rod 43 below the fixed disk 42. A first spring 45 is fixedly connected between the moving disk 44 and the fixed disk 42. Threads are provided at the top of the lifting rod 43. A bearing 46 is arranged above the fixed disk 42 inside the sliding groove 41. The outer ring of the bearing 46 is fixedly connected to the sliding groove 41. The inner ring of the bearing 46 is fixedly connected to a sleeve rod 47. The threads provided at the top of the lifting rod 43 are threadedly connected to the sleeve rod 47. A gear 48 is fixedly connected to the top of the sleeve rod 47. The auxiliary alignment component 4 further includes a rack 410 slidably connected to the top of the cross beam 3. The outside of the gear 48 is engaged with the rack 410. An insertion part 49 is arranged on the left side of the rack 410. A clamping component 5 is arranged at the corresponding position of the insertion part 49 on the right side of the mounting bracket 2. The clamping component 5 includes a fixed seat 51 fixedly connected to the right side of the mounting bracket 2. A clamping groove 52 is opened on the right part of the fixed seat 51. The mounting bracket 2 includes a connecting plate 21 detachably connected to the right side of the column 1. A cross plate 22 is fixedly connected to the right side of the connecting plate 21. A limiting plate 23 is fixedly connected together between the top of the cross plate 22 and the connecting plate 21. The front and rear ends of the left part of the cross beam 3 are detachably connected with a blocking plate 10. A bent frame 11 is fixedly connected to the rear end of the top of the cross beam 3. The top of the limiting plate 23 is inclined.

[0032] By adopting the above technical solution, the detachable connection methods used in this device can all adopt bolt connection. During use, a part of the mounting bracket 2 is installed on the right side of the column 1, and the cross beam 3 to be installed is bolted to the blocking plates 10 at both front and rear ends. The cross beam 3 is lifted by an external hoisting device and placed above the cross plate 22, and then slowly lowered until the bottom of the cross beam 3 fits against the top of the cross plate 22. During this process, workers need to hold the cross beam 3 by hand so that when the cross beam 3 and the blocking plates 10 are lowered, the limiting plate 23 passes through between the two blocking plates 10. The blocking plates 10 and the limiting plate 23 play a role in limiting the descent of the cross beam 3. Under the elastic force of the first spring 45, in the initial state, the bottom position of the lifting rod 43 extends from the bottom of the cross beam 3 before the bottom of the cross beam 3 fits against the top of the cross plate 22. As the cross beam 3 drives the lifting rod 43 to descend and the cross beam 3 approaches the cross plate 22, under the limiting action of the cross plate 22, the lifting rod 43 slides inside the fixed disk 42, so that the moving disk 44 moves upward along with the fixed disk 42. At this time, the first spring 45 is compressed. Since the lifting rod 43 moves upward, under the action of threaded connection, the sleeve rod 47 drives the gear 48 to rotate. Under the meshing action of the gear 48 and the rack 410, when the gear 48 rotates, the rack 410 can be made to move in the left direction, so as to facilitate the left part of the insertion part 49 to be inserted into the card slot 52 opened inside the fixed seat 51. This can limit the position of the insertion part 49 and the cross beam 3 and prevent the cross beam 3 from being displaced. Under the combined action of the auxiliary alignment assembly 4, the clamping assembly 5, the limiting plate 23 and the blocking plates 10, it is beneficial to limit and position the cross beam 3 before installing screws to fix the cross beam 3, so as to facilitate the alignment of the holes opened on the cross beam 3 and the holes opened on the cross plate 22. At this time, the cross beam 3 and the cross plate 22 can be fixed by bolts, improving the installation efficiency of the cross beam 3.

[0033] The top of the limiting plate 23 is inclined. Under the action of the top inclined design, it is convenient for the two blocking plates 10 to be located on both sides of the limiting plate 23 when descending. 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.

[0034] It should be noted that the pitch of the thread opened at the top of the lifting rod 43 is set relatively large. Such a design is beneficial to reducing the friction between the thread of the lifting rod 43 and the sleeve rod 47 and facilitating the rotation of the sleeve rod 47 when the lifting rod 43 moves. And its threaded connection method is similar to the connection method between the screw part and the flying saucer part of the hand-pushed flying saucer.

[0035] The bottom of the bent frame 11 fits against the top surface of the rack 410, which is beneficial to enhancing the structural stability at the rack 410 and the insertion part 49.

[0036] Specifically, such as Figures 2 to 7As shown, a moving groove 53 is provided at the top of the right side of the fixed seat 51 within the card slot 52. The insertion portion 49 includes a sleeve plate 491 fixedly connected to the left side of the rack 410. A through plate 492 is slidably connected to the left portion of the sleeve plate 491. A second spring 493 is fixedly connected between the right side of the through plate 492 and the sleeve plate 491.

[0037] By adopting the above technical solution, before the bottom of the cross beam 3 fits against the cross plate 22, the left side of the through plate 492 contacts the fixed seat 51. As the cross beam 3 continues to move downward, the rack 410 drives the through plate 492 and the sleeve plate 491 to move 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 as the cross beam 3 moves downward, the left portion of the through plate 492 slides up and down inside the moving groove 53.

[0038] When the through plate 492 reaches the part of the card slot 52, under the elastic force of the second spring 493, it is convenient for the through plate 492 to move to the left. At this time, the through plate 492 is inserted into the inside of the card slot 52, which is conducive to limiting the cross beam 3.

[0039] And such a design enables the through plate 492 to be inserted deeper into the card slot 52, improving the limiting effect on the cross beam 3.

[0040] Specifically, as Figures 2 to 5 shown, a blocking assembly 6 is provided at the bottom of the lifting rod 43. The blocking assembly 6 includes a round rod 61 fixedly connected to the bottom of the lifting rod 43. A swing plate 62 is rotatably connected between the front and rear ends of the outer wall of the round rod 61. A torsion spring 63 is fixedly connected between the round rod 61 and the swing plate 62. A placing groove 16 is provided at the top of the cross plate 22 below the swing plate 62.

[0041] 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 hoisting and placing the cross beam 3 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, then 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 conducive to horizontally applying an elastic force to the cross beam 3, so that the cross beam 3 is in a relatively horizontal state when descending, thereby ensuring that the insertion portion 49 is aligned with the card slot 52, thus improving the efficiency of the insertion portion 49 inserting into the card slot 52. Such a design further improves the installation efficiency of the cross beam 3. After installation, the swing plate 62 is hidden in the placing groove 16.

[0042] Specifically, as Figures 2 to 7As shown, a limiting component 7 is arranged inside the fixing base 51. The limiting component 7 includes a small plate 71 slidably connected inside the clamping groove 52. A medium bag 72 is fixedly connected to the left side of the small plate 71. The limiting component 7 further includes a sleeve 73 fixedly connected inside the fixing base 51. 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. A third spring 76 is fixedly connected between the top of the piston plate 74 and the sleeve 73. A conduit 77 is fixedly inserted between the medium bag 72 and the sleeve 73. The elastic force of the second spring 493 is greater than that of the third spring 76.

[0043] Above the part of the fixing base 51 close to the clamping groove 52, it is spliced with other parts of the fixing base 51 during the production of the device to jointly form a complete fixing base 51, so as to facilitate the installation of components such as the sleeve 73, the piston plate 74, and the blocking rod 75 inside the fixing base 51 during the production of the device.

[0044] By adopting the above technical solution, the size of the clamping groove 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 inside of the clamping groove 52. When the through plate 492 is inserted into the clamping groove 52, under the elastic force of the second spring 493, the through plate 492 is inserted into the inside of the clamping groove 52. At this time, since the elastic force of the second spring 493 is greater than that 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 drive the blocking rod 75 to move downward. This design facilitates the blocking rod 75 to squeeze the top of the through plate 492, improves the limiting effect on the through plate 492, and further improves the limiting effect on the cross beam 3, thus further facilitating the alignment of the holes opened on the cross beam 3 and the holes opened on the cross plate 22 and improving the installation efficiency.

[0045] Specifically, as Figure 6 and Figure 7 shown, both the sleeve 73 and the blocking rod 75 are inclined.

[0046] By adopting the above technical solution, the inclined setting of the blocking rod 75 makes it such that even when the cross beam 3 is inclined and its left side presses upward on the blocking rod 75, under the action of the inclined design of the blocking rod 75, the applied force is not parallel to the blocking rod 75, thereby reducing the effect of the blocking rod 75 being pushed open. This design is conducive to improving the limiting effect of the blocking rod 75 on the through plate 492 and further improving the limiting effect on the cross beam 3.

[0047] Specifically, as Figures 1 to 3 and Figure 8As shown, mounting brackets 8 are fixedly connected to both the top and bottom ends of the connecting plate 21. A small shaft 9 is fixedly connected inside the mounting bracket 8. A left rod 12 is movably connected to the outer wall of the small shaft 9. A rotating rod 13 is rotatably connected to the right side of the left rod 12. A thread is provided on the inner right side of the rotating rod 13. A hook rod 14 is threadedly connected to the inner right side of the rotating rod 13. Hook brackets 15 are detachably connected to both the top and bottom ends of the cross beam 3. The right side of the hook rod 14 is snapped into the inside of the hook bracket 15.

[0048] 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 facilitates the swinging of the left rod 12, the rotating rod 13, and the hook rod 14. After installing the cross beam 3 with bolts and installing the hook bracket 15 with bolts, then swing and rotate the left rod 12 so that the hook of the hook rod 14 is inserted into the inside of the hook bracket 15. Subsequently, manually rotate the rotating rod 13. Under the action of the threaded connection, the hook rod 14 moves, causing the hook rod 14 to tighten at the hook bracket 15. Such a design is conducive to improving the stability of the mechanism during the installation of the hook bracket 15.

[0049] Working principle: Install part of the mounting bracket 2 on the right side of the column 1. Install the cross beam 3 to be installed on the blocking plates 10 at both front and rear ends through bolts. Lift the cross beam 3 by an external hoisting device and place it above the cross plate 22, and slowly lower the cross beam 3 until the bottom of the cross beam 3 fits against the top of the cross plate 22. During this process, workers need to hold the cross beam 3 by hand so that when the cross beam 3 and the blocking plates 10 descend, the limiting plate 23 passes through between the two blocking plates 10. The blocking plates 10 and the limiting plate 23 play a role in limiting the descent of the cross beam 3. Under the elastic force of the first spring 45, in the initial state, the bottom of the lifting rod 43 extends from the bottom of the cross beam 3 before the bottom of the cross beam 3 fits against the top of the cross plate 22. As the cross beam 3 drives the lifting rod 43 to descend and the cross beam 3 approaches the cross plate 22, under the limiting action of the cross plate 22, the lifting rod 43 slides inside the fixed disk 42, so that the moving disk 44 moves upward with the fixed disk 42. At this time, the first spring 45 is compressed. Since the lifting rod 43 moves upward, under the action of threaded connection, the sleeve rod 47 drives the gear 48 to rotate. Under the action of the gear 48 meshing with the rack 410, when the gear 48 rotates, the rack 410 can be moved to the left, so that the left part of the insertion part 49 is inserted into the card slot 52 opened inside the fixed seat 51, which can limit the position of the insertion part 49 and the cross beam 3 and prevent the cross beam 3 from being displaced. Under the combined action of the auxiliary alignment assembly 4, the clamping assembly 5, the limiting plate 23 and the blocking plates 10, it is beneficial to limit and position the cross beam 3 before installing the screws to fix the cross beam 3, so as to facilitate the alignment of the holes opened on the cross beam 3 with the holes opened on the cross plate 22. At this time, the cross beam 3 and the cross plate 22 can be fixed by bolts, improving the installation efficiency of the cross beam 3.

[0050] When the through plate 492 reaches the part of the card slot 52, under the elastic force of the second spring 493, it is convenient for the through plate 492 to move to the left. At this time, the through plate 492 is inserted into the inside of the card slot 52, which is beneficial to limit the cross beam 3. And such a design enables the through plate 492 to be inserted deeper into the inside of the card slot 52, improving the limiting effect on the cross beam 3.

[0051] Under the elastic force of the torsion spring 63 itself, the lifting rod 43 and the swing plate 62 are in a perpendicular state. When the cross beam 3 is placed downward during hoisting, the swing plate 62 at the bottom of the lifting rod 43 first contacts the top of the horizontal plate 22. If the cross beam 3 is in an inclined state when placed downward, then the swing plate 62 is also in an inclined state when it contacts the horizontal 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 horizontally apply an elastic force to the cross beam 3, so that the cross beam 3 is in a relatively horizontal state when descending, thus ensuring that the insertion part 49 is aligned with the card slot 52, thereby improving the efficiency of inserting the insertion part 49 into the card slot 52. Such a design further improves the installation efficiency of the cross beam 3.

[0052] When the through plate 492 is inserted into the card slot 52, under the elastic force of the second spring 493, the through plate 492 is inserted into the inside of the card slot 52. At this time, since the elastic force of the second spring 493 is greater than that of the third spring 76, the through plate 492 squeezes the small plate 71, causing the small plate 71 to move to the left, so that the medium bag 72 is squeezed, 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. Such a design facilitates the blocking rod 75 to squeeze the top of the through plate 492, improves 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 and the holes opened on the horizontal plate 22, improving the installation efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
