Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an assembled high-strength earthquake-resistant steel structure for steel structure buildings. Background Art

[0002] Earthquake-resistant steel structure is a special steel structure construction technology designed to improve the earthquake resistance of buildings. This technology uses high-strength steel and advanced assembly technology to make steel structure buildings have better earthquake resistance and higher bearing capacity. Specifically, this earthquake-resistant steel structure uses high-strength steel, and after precise calculation and analysis, a reasonable component section and connection method are designed to make the entire structure have sufficient bearing capacity and stability.

[0003] Existing earthquake-resistant steel structures usually have a top plate on the top of the support column in contact with the cross beam to increase the contact area between the support column and the cross beam. When the top plate is subjected to pressure from the cross beam, the top plate will transfer the pressure to the support column, which will then resist the pressure from the cross beam. The top plate is usually composed of a whole plate. When the top plate is pressed by the cross beam, the contact area between the top plate and the cross beam is limited. At the same time, because the contact between the top plate and the cross beam is relatively uneven, the pressure of the cross beam on the top plate will increase, which may cause deformation of the top plate and other problems. Therefore, the utility model aims to provide an earthquake-resistant steel structure that can adapt to beams of different areas. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figures 1 to 4 According to an embodiment of the utility model, a technical solution is provided: an assembled high-strength earthquake-resistant steel structure for a steel structure building, comprising a cross beam 1, a bottom plate 2 and a support column 3 arranged on the bottom plate 2, and also comprising a first top plate 4, which is arranged on the top of the support column 3; and a second top plate 5, which is rotatably connected to the support column 3 through a connecting rod 15, and a fixing mechanism 6 is provided between the second top plate 5 and the support column 3, and the fixing mechanism 6 is used to fix the second top plate 5 relative to the support column 3 to limit or allow the second top plate 5 to move relative to the support column 3. When the second top plate 5 is restricted from moving by the fixing mechanism 6, it is in a horizontal state with the first top plate 4.

[0025] The assembled high-strength earthquake-resistant steel structure for steel structure buildings adopts the above-mentioned structure. When the user installs the device, the support column 3 is first placed under the beam 1, and then the second top plate 5 is rotated until the second top plate 5 is horizontal with the first top plate 4, and then the second top plate 5 and the support column 3 are relatively fixed using the fixing mechanism 6. The combination of the second top plate 5 and the first top plate 4 increases the bearing area of ​​the support column 3 on the beam 1, averages the pressure of the beam 1 on the first top plate 4 and the second top plate 5, prevents the pressure of the beam 1 on the first top plate 4 and the second top plate 5 from being too great, thereby deforming the first top plate 4 and the second top plate 5 and increasing the service life of the first top plate 4 and the second top plate 5.

[0026] In this embodiment, the fixing mechanism 6 includes a fixing block 17 and a screw 16, the fixing block 17 is fixed to the bottom of the second top plate 5, and the screw 16 is threadedly connected to the fixing block 17 and the support column 3; when the user needs to place the second top plate 5 at the same level as the first top plate 4 and limit the movement of the second top plate 5, the second top plate 5 is rotated until the second top plate 5 is horizontal with the first top plate 4, and then, the screw 16 is threadedly connected to the fixing block 17, and then, the screw 16 is threadedly connected to the support column 3. At this time, the support column 3, the connecting rod 15 and the screw 16 are in a triangular shape, which has good stability.

[0027] Alternatively, the fixing mechanism 6 can also be set to other suitable structures or forms, for example, using a polygonal plate body to movably insert and fix the plate and the support column 3, and the friction between the plate body and the support column 3 to fix the second top plate 5 relative to the support column 3.

[0028] In this embodiment, an extension plate 9 is provided at both ends of the second top plate 5, and an extension mechanism 7 is provided between the extension plate 9 and the second top plate 5. The extension mechanism 7 is used to move the two extension plates 9 relative to the second top plate 5 to increase or decrease the distance between the two extension plates 9 and the second top plate 5. The second top plate 5 and the extension plates 9 are in a horizontal state; when the user needs to expand the bearing area of ​​the second top plate 5, the extension mechanism 7 is used to expand the distance between the extension plate 9 and the second top plate 5. When the second top plate 5 is subjected to the pressure of the beam 1, the extension plate 9 can disperse the pressure of the beam 1 on the second top plate 5.

[0029] In this embodiment, the extension mechanism 7 includes a guide rod 10 and a limit rod 11. The guide rod 10 is fixed on one end of the second top plate 5 facing the extension plate 9. The guide rod 10 movably passes through the extension plate 9. The limit rod 11 is arranged at the free end of the guide rod 10. A locking mechanism 8 is provided between the guide rod 10 and the second top plate 5. The locking mechanism 8 is used to fix the second top plate 5 and the guide rod 10 relative to each other to limit or allow the second top plate 5 to move relative to the guide rod 10. When the user needs to extend the second top plate 5, the two extension plates 9 are pulled away from the second top plate 5 to a predetermined distance of the user. At this time, the locking mechanism 8 is used to fix the extension plate 9 and the guide rod 10 relative to each other. When the second top plate 5 is subjected to the pressure of the beam 1, the extension plate 9 can disperse the pressure of the beam 1 on the second top plate 5.

[0030] In this embodiment, the locking mechanism 8 includes locking holes 12 and a locking rod 13 that are spaced apart along the length direction of the guide rod 10. The locking rod 13 movably penetrates the second top plate 5 and extends into the locking hole 12. When the user needs to relatively fix the guide rod 10 and the extension plate 9, the guide rod 10 and the extension plate 9 can be relatively fixed by movably inserting the locking rod 13 into the extension plate 9 and at least partially inserting the locking rod 13 into the locking hole 12.

[0031] Alternatively, the locking mechanism 8 may also be configured as other suitable structures or forms, for example, by using a screw to be threadedly connected to the extension plate 9 , and screwing the screw into the extension plate 9 to abut against the guide rod 10 .

[0032] In this embodiment, a limit plate 14 is provided at a section of the locking rod 13 facing away from the second top plate 5; when the user inserts the locking rod 13 into the extension plate 9, the limit plate 14 prevents the locking rod 13 from being completely immersed in the extension plate 9, making it difficult to take the locking rod 13 out of the extension plate 9.

[0033] Working principle: When the user installs the device, first place the support column 3 under the beam 1, then rotate the second top plate 5 until the second top plate 5 is horizontal with the first top plate 4, and then rotate the second top plate 5 until the second top plate 5 is horizontal with the first top plate 4, and then use the screw rod 16 to thread the fixing block 17, and then thread the screw rod 16 to the support column 3. At this time, the support column 3, the connecting rod 15 and the screw rod 16 are in a triangular shape, which has good stability. The combination of the second top plate 5 and the first top plate 4 increases the bearing area of ​​the support column 3 on the beam 1, averages the pressure of the beam 1 on the first top plate 4 and the second top plate 5, and prevents the beam 1 from exerting excessive pressure on the first top plate 4 and the second top plate 5. The first top plate 4 and the second top plate 5 are pressed to deformation, thereby increasing the service life of the first top plate 4 and the second top plate 5; when the user needs to expand the bearing area of ​​the second top plate 5, the two extension plates 9 are pulled away from the second top plate 5 to a predetermined distance of the user. At this time, the locking rod 13 is movably inserted into the extension plate 9 and at least a portion of the locking rod 13 is inserted into the locking hole 12, so that the guide rod 10 and the extension plate 9 can be relatively fixed. When the user inserts the locking rod 13 into the extension plate 9, the limit plate 14 prevents the locking rod 13 from being completely immersed in the extension plate 9, making it difficult to take the locking rod 13 out of the extension plate 9. When the second top plate 5 is subjected to the pressure of the cross beam 1, the extension plate 9 can disperse the pressure of the cross beam 1 on the second top plate 5.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
