Description

Technical Field

[0001] The invention relates to the technical field of building steel structures, in particular to a building steel structure that is easy to assemble. Background Art

[0002] During the construction of some factory buildings, steel structures need to be assembled and welded. The current mainstream steel structure assembly method is usually to align the ends of the two steel structures, and then use the connecting ear plates welded in advance on the upper and lower steel structures to align them. After aligning the ear plates, use bolts and nuts to screw the ear plates on the two steel structures together, and then weld the joints of the upper and lower steel structures. After welding, cut off the ear plate position, and then grind the cutting marks to complete the steel structure docking.

[0003] The existing methods of connecting steel structures on the market are usually to connect two steel structures up and down by crane, because steel structures are usually large in size and heavy, and difficult to lift manually. The crane controls the rough position movement of the steel structure, and then the hoisted steel structure is manually supported to connect it to the end of the steel structure to be connected. Manual connection requires repeated adjustments, and the connection accuracy is poor, which is time-consuming and labor-intensive, and does not meet actual assembly requirements. Summary of the invention

[0006] As an optional solution for an easy-to-assemble building steel structure described in the present invention, a first ball is provided on the outer wall of the first rotating disk, and a threaded groove for guiding the moving direction of the first ball is opened on the inner wall of the rotating frame, and the first ball slides in the threaded groove.

[0007] As an optional solution of the building steel structure that is easy to assemble according to the present invention, wherein: a second guide rod is fixed to the outer wall of the first sleeve, a second return spring is fixed between the outer wall of the rotating frame and the outer wall of the first sleeve, the second return spring is sleeved on the outer wall of the second guide rod, a through groove is opened on the outer wall of the first sleeve, and the rotating frame slides in the through groove; A silicon rubber friction convex block for fixing the position of the first sleeve is fixed on the end of the rotating frame.

[0008] As an optional solution for an easy-to-assemble building steel structure described in the present invention, a second inclined block is fixed to the outer wall of the sliding plate, a first guide rod is fixed to the outer wall of the second sleeve, a second ball is installed at the end of the first guide rod, and the second ball is in contact with the inclined surface of the second inclined block.

[0009] As an optional solution for an easy-to-assemble building steel structure described in the present invention, the outer walls of the first movable frame and the second movable frame are both fixed with a second guide rod, the end of the second guide rod is installed with a third ball, and the third ball is in conflict with the inclined surface of the first inclined surface block.

[0010] As an optional solution for an easy-to-assemble building steel structure described in the present invention, there are two fixed columns, and the outer walls of the two fixed columns are rotatably provided with a rotating shaft, the outer wall of the rotating shaft is fixed to the outer wall of the contact plate, and the outer wall of the rotating shaft is sleeved with a torsion spring, one end of the torsion spring is fixed to the outer wall of the fixed column, and the other end of the torsion spring is fixed to the outer wall of the contact plate.

[0011] As an optional solution for an easily assembled building steel structure described in the present invention, two third guide rods are fixed to the outer wall of the first sleeve, and the first movable frame and the second movable frame are respectively slidably matched with the two third guide rods.

[0012] As an optional solution of the building steel structure that is easy to assemble described in the present invention, a blocking piece for limiting the position of the sliding plate is fixed to the outer wall of the bolt.

[0013] As an optional solution of the building steel structure that is easy to assemble described in the present invention, a roller is rotatably provided on the outer wall of the resistance plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by initially rotating the bolts, the rotating frames on both sides can be pressed tightly against the outer wall of the first steel frame with the corresponding silicone rubber friction protrusions, which can cause the first sleeve to stop at any height outside the first steel frame. This arrangement can accurately position the rotating frame and the surrounding mechanisms at any position on the outer wall of the first steel frame according to different situations, making it adaptable and usable in a wider range. The position fixation of the first sleeve can be released by reversely screwing the bolts, and it can be quickly dismantled. This arrangement can be used in more steel structure docking and reused repeatedly.

[0015] In the present invention, by continuing to rotate the bolt, not only can the silicone rubber friction protrusion be pressed on the surface of the first steel frame with a greater pressing force, thereby improving the fixing stability of the position of the first sleeve, but also the upward movement of the second sleeve will cause the first movable frame and the second movable frame to approach each other. The approach of the first movable frame and the second movable frame will bring the multiple contact plates of their outer walls closer to the four sides of the second steel frame, further limiting the range of movement and shaking of the second steel frame during hoisting, and the approach of the first movable frame and the second movable frame will contact the second steel frame, so that the second steel frame is further aligned with the first steel frame up and down, thereby making it easier to accurately dock, so that it can more accurately dock with the end of the first steel frame. It can be seen that by continuing to rotate the bolt, on the one hand, the position of the first sleeve can be further restricted and tightened, and on the other hand, the second steel frame and the first steel frame can be further placed in the same straight line, making their docking easier and more accurate.

[0016] In the present invention, by rotating the bolts again, the first moving frame and the second moving frame are forced to approach each other further. At this time, the first moving frame and the second moving frame will bring the corresponding contact plates close to the four sides of the second steel frame again. As the contact plates continue to move, the lower ends of the contact plates contact the fourth ball and the fourth guide rod, causing the contact plates to rotate under force. The rotation of the contact plates causes the rollers at their ends to tilt, causing the end of the contact plates to clamp the outer wall of the second steel frame. The clamping of the four sides causes the second steel frame to be aligned in a straight line with the end of the first steel frame below. At this time, the crane can move the second steel frame downward to complete precise docking, and during the entire process, only the bolts need to be tightened, without the need for excessive manual adjustment. It can be seen that by rotating the bolts to different degrees, the restriction effect, as well as the clamping and calibration position effects of the second steel frame can be achieved.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0027] Embodiment 1: This embodiment aims to solve the problem that the crane can only control the rough position movement of the steel structure, and then manually support the hoisted steel structure to dock it at the end of the steel structure to be docked. Manual docking requires repeated adjustments, and the docking accuracy is poor, time-consuming and labor-intensive, and does not meet the actual assembly requirements. Please refer to Figure 1-Figure 8 , a building steel structure that is easy to assemble, comprising a first steel frame 2, a first sleeve 3 is slidably sleeved on the outer wall of the first steel frame 2, a second sleeve 18 is slidably sleeved on the outer wall of the first sleeve 3, a first inclined surface block 21 is fixed on the outer wall of the second sleeve 18, and the outer wall of the first inclined surface block 21 is set as an inclined surface; The outer wall of the first sleeve 3 is slidably sleeved with a first moving frame 25 and a second moving frame 26, the inner wall of the first moving frame 25 is slidably sleeved with a third guide rod 27, the inner wall of the second moving frame 26 is fixed to the outer wall of the third guide rod 27, a third return spring 28 is sleeved on the third guide rod 27, the outer wall of the first moving frame 25 is fixed to one end of the third return spring 28, one end of the third return spring 28 is fixed to the outer wall of the second moving frame 26, and the provision of the third return spring 28 facilitates subsequent resetting; The outer walls of the first moving frame 25 and the second moving frame 26 are fixed with fixed columns 29, and the outer walls of the fixed columns 29 are provided with a plurality of abutment plates 32 for limiting the moving track of the second steel frame 1, and the abutment plates 32 are used to limit and clamp the second steel frame 1 so that it gradually aligns with the upper and lower positions of the first steel frame 2; The outer wall of the first sleeve 3 is provided with a first guide rod 4, and a sliding plate 5 is slidingly provided on the first guide rod 4, and a bolt 8 is inserted on the sliding plate 5. A first rotating disk 9 is installed on the side of the bolt 8 close to the first sleeve 3, and a second rotating disk 13 is rotatably provided on the outer wall of the first rotating disk 9. A rotating frame 11 is sleeved on the outer wall of the second rotating disk 13, and a first return spring 14 is fixed between the inner wall of the rotating frame 11 and one side of the second rotating disk 13. When the bolt 8 is turned, the bolt 8 rotates synchronously with the first rotating disk 9 at the end thereof, and while the first rotating disk 9 rotates, it drives the first ball 10 on its outer wall along the thread groove 12 The first rotating disk 9 starts to move in the trajectory, and during the movement, the first rotating disk 9 continuously moves toward the inner wall of the rotating frame 11, and during the movement of the first rotating disk 9, the second rotating disk 13 moves synchronously, and during the movement of the second rotating disk 13, the first return spring 14 is pressed. When the first return spring 14 is pressed, the pressing force is transmitted to the rotating frame 11 along with the first return spring 14. As the pressing force is applied to the rotating frame 11, the rotating frame 11 will first press the second return spring 16 to compress it. As the second return spring 16 is compressed, the rotating frame 11 will move toward the through slot 301 along the guidance of the second guide rod 15; The outer wall of the first rotating disk 9 is provided with a first ball 10, which is rotatably arranged on the outer wall of the first rotating disk 9. The inner wall of the rotating frame 11 is provided with a thread groove 12 for guiding the moving direction of the first ball 10. The first ball 10 slides in the thread groove 12. In this way, when the bolt 8 is rotated, the first ball 10 can slide along the thread groove 12, thereby moving the bolt 8; A second guide rod 15 is fixed to the outer wall of the first sleeve 3, a second return spring 16 is fixed between the outer wall of the rotating frame 11 and the outer wall of the first sleeve 3, the second return spring 16 is sleeved on the outer wall of the second guide rod 15, a through groove 301 is formed on the outer wall of the first sleeve 3, and the rotating frame 11 slides in the through groove 301; A silicone rubber friction bump 17 for fixing the position of the first sleeve 3 is fixed to the end of the rotating frame 11 , and the elastic force of the first return spring 14 is greater than the elastic force of the second return spring 16 .

[0028] In this embodiment: In order to more quickly dock and assemble the steel structure, before docking the steel structure, first, the first sleeve 3 is put on the outer wall of the assembled first steel frame 2, and after sliding it to a suitable position, the bolts 8 on both sides are then screwed at the same time to promote the movement of the rotating frame 11, so that the silicone rubber friction protrusion 17 at its end contacts the outer wall of the first steel frame 2 through the through groove 301, and the two silicone rubber friction protrusions 17 on both sides are pressed and contacted at the same time. The silicone rubber material has good friction. Continuing to press causes the silicone rubber to deform and increase the friction, so that the position of the first sleeve 3 is fixed at this height. At this time, the end of the second steel frame 1 is moved to the center position of the contact plates 32 on the four sides by a crane for suspension.

[0029] The effect achieved by this embodiment is that the first sleeve 3 and the peripheral mechanism can be positioned at any height position of the first sleeve 2, so as to facilitate the smooth progress of subsequent alignment, restriction and other tasks.

[0030] Embodiment 2: This embodiment aims to solve the problem of how to further fix the position of the assembly and how to position the first steel frame and the second steel frame after the assembly is fixed in position in Embodiment 1. Figure 1-Figure 8, a building steel structure that is easy to assemble, the outer wall of the sliding plate 5 is fixed with a second inclined surface block 6, the outer wall of the second sleeve 18 is fixed with a first guide rod 19, the end of the first guide rod 19 is installed with a second ball 20, the second ball 20 is in contact with the inclined surface of the second inclined surface block 6, as the first rotating disk 9 and the second rotating disk 13 continue to move, the first return spring 14 is continuously compressed, at this time, the silicone rubber friction protrusion 17 has been in contact with the outer wall of the first steel frame 2 and cannot continue to move, therefore, at this time, as the first return spring 14 continues to be compressed and deformed, its compressed pressing force also increases with the compression length. The pressing force on the rotating frame 11 and the silicone rubber friction protrusion 17 is also increasing, so that the friction between the silicone rubber friction protrusion 17 and the outer wall of the first steel frame 2 is greater, and the position of the first sleeve 3 is fixed more firmly. The movement of the sliding plate 5 brings the second inclined surface block 6 of its outer wall to move synchronously, and the lateral movement of the second inclined surface block 6 causes the inclined surface of its outer wall to contact the second ball 20. The contact causes the second ball 20 to slide along the inclined surface of the outer wall of the second inclined surface block 6, and causes the second inclined surface block 6 to gradually rise with the first guide rod 19. When the first guide rod 19 rises, it brings the second sleeve 18 to rise synchronously; The outer walls of the first moving frame 25 and the second moving frame 26 are both fixed with a second guide rod 24, and the end of the second guide rod 24 is mounted with a third ball 23, and the third ball 23 abuts against the inclined surface of the first inclined surface block 21; The outer wall of the bolt 8 is fixed with a baffle 801 for limiting the position of the sliding plate 5. Two baffles 801 are provided, which are respectively arranged on both sides of the sliding plate 5 to facilitate limiting the sliding of the sliding plate 5 on the bolt 8. The outer wall of the resistance plate 32 is rotatably provided with a roller 33. Since a plurality of resistance plates 32 are provided, the resistance plates 32 in four directions simultaneously press the four sides of the outer wall of the second steel frame 1, so that the position of the second steel frame 1 is now in the same straight line as the position of the first steel frame 2. The roller 33 can further align the first steel frame 2 with the second steel frame 1. When the second steel frame 1 is hung down, the friction between the outer surface of the second steel frame 1 and the outer surface of the resistance plate 32 can be reduced, so that the second steel frame 1 can be smoothly hung down and docked with the first steel frame 2.

[0031] In this embodiment: at this time, the bolts 8 on both sides continue to rotate simultaneously. As the bolts 8 continue to enter the rotating frame 11 with the first rotating disk 9 and the second rotating disk 13, the sliding plate 5 also moves synchronously. After the second sleeve 18 rises, it also rises with the two first inclined plane blocks 21 on its outer wall. The rise of the first inclined plane block 21 causes the inclined surface of its outer wall to conflict with the third ball 23. The conflict causes the third ball 23 to move with the second guide rod 24 toward the direction of the first inclined plane block 21. Since the two first inclined blocks 21 are axially symmetrically arranged, the second guide rods 24 on both sides are close to each other, and then the second guide rods 24 on both sides are close to each other, and the corresponding first moving frame 25 and the second moving frame 26 are close to each other under the guidance of the third guide rod 27, and are guided by the third guide rod 36 during the movement. At this time, the contact plates 32 on the four sides further limit and clamp the second steel frame 1 at the center position at the same time.

[0032] And they are compressed while approaching. When the first mobile frame 25 and the second mobile frame 26 approach each other, the first mobile frame 25 and the second mobile frame 26 will move synchronously with the corresponding contact plates 32, causing the contact plates 32 on the four sides to simultaneously approach the position of the second steel frame 1. After the outer wall of the contact plate 32 contacts the outer wall of the second steel frame 1, the suspended second steel frame 1 will be pressed from the four sides to gradually approach the center point of the first steel frame 2, and the movable range of the second steel frame 1 during the lifting process is reduced, making the subsequent docking more precise. The effect achieved by this embodiment can, on the one hand, further limit and tighten the position of the first sleeve 3, and on the other hand, further achieve the second steel frame 1 and the first steel frame 2 to be in the same straight line, making their docking easier and more precise.

[0033] Embodiment 3: This embodiment is intended to facilitate solving the problem of how to further assist in docking and aligning the first steel frame and the second steel frame after preliminary positioning in Embodiment 2. Figure 1-Figure 8 , a building steel structure that is easy to assemble, wherein two fixed columns 29 are provided, and a rotating shaft 30 is rotatably provided on the outer wall of the two fixed columns 29, and the outer wall of the rotating shaft 30 is fixed to the outer wall of the contact plate 32, and a torsion spring 31 is sleeved on the outer wall of the rotating shaft 30, and one end of the torsion spring 31 is fixed to the outer wall of the fixed column 29, and the other end of the torsion spring 31 is fixed to the outer wall of the contact plate 32, and the rotation of the contact plate 32 causes the protruding part of the end of the contact plate 32 to be pressed against the outer wall of the second steel frame 1, and the contact causes the contact plate 32 to be forced to rotate along the rotating connection of the fixed column 29 with the rotating shaft 30, and the torsion spring 31 is twisted during the rotation to store force for subsequent reset; A plurality of fourth guide rods 34 are fixed to the outer wall of the first sleeve 3, and fourth balls 35 are rotatably arranged at the ends of the fourth guide rods 34; Two third guide rods 36 are fixed to the outer wall of the first sleeve 3 , and the first moving frame 25 and the second moving frame 26 are slidably matched with the two third guide rods 36 respectively.

[0034] In this embodiment: at this time, as the bolt 8 is continuously turned, the first moving frame 25 and the second moving frame 26 will be closer to each other. As the first moving frame 25 and the second moving frame 26 continue to be closer, the abutment plate 32 moves accordingly and the lower half thereof abuts against the fourth ball 35. Since a plurality of contact plates 32 are provided, the contact plates 32 in four directions simultaneously press the four sides of the outer wall of the second steel frame 1, so that the position of the second steel frame 1 is now in the same straight line as the position of the first steel frame 2, so that the docking is more accurate. At this time, it is only necessary to gradually lower the second steel frame 1 by means of a crane. When the second steel frame 1 is lowered, its outer wall will slide against the roller 33 provided with the outer wall of the contact plate 32 for rotation, thereby reducing the friction resistance when the second steel frame 1 is lowered for docking, and the accurate docking of the second steel frame 1 and the first steel frame 2 is completed. Only welding of the joints is required to complete the assembly. The whole process is simple and can be achieved one by one by screwing the bolts 8. After the docking is completed, the bolt 8 can be screwed in the reverse direction to make it rotate in the reverse direction with the first rotating disk 9, prompting the first ball 10 to move in the reverse direction along the trajectory of the thread groove 12, so that the second rotating disk 13 moves in the reverse direction. At this time, the first return spring 14 begins to rebound, and finally the rotating frame 11 and the silicone rubber friction protrusion 17 release the pressure on the surface of the first steel frame 2, so that the first sleeve 3 can be removed, and the first sleeve 3 and a series of structures can be slid upward to remove, and the remaining steel structures that need to be docked can be repeatedly assembled and docked quickly. The whole process does not require too much manual adjustment. By rotating the bolt 8 to different degrees, the effects of restriction and positioning, as well as the clamping and calibration position of the second steel frame can be achieved.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
