Description

Technical Field

[0001] The present invention relates to the technical field of devices for supporting multi-layer steel structure components, and in particular to a component and an assembly method for supporting a multi-layer steel structure based on an external steel. Background Art

[0002] A component of multi-layer steel structure based on external steel supports, it consists of multiple layers of horizontal steel beams and vertical steel columns connected into a frame through nodes, and then matched with different forms of steel supports such as single inclined rods and cross rods. It is mostly made of steel sections and steel pipes. It has both the bending resistance of steel frames and the shear and compression resistance of steel supports, and can jointly bear vertical and horizontal loads, effectively improving lateral stiffness. It is often used in high-rise buildings, large-span factories, stadiums, etc.

[0003] In the prior art, existing supporting multi-layer steel structures are often connected by welding or bolts. After the connection, since the device is a multi-layer supporting steel structure, the main stress points between the layers are also high-rigidity connections such as welding and bolt connections. When used specifically, this connection method can withstand high-intensity vibration environments, so that the device connection will not be loose. However, when facing different environments such as high-frequency and low-vibration environments, the high-rigidity connection is difficult to absorb the stress generated by smaller vibrations. At this time, the main stress points between the layers are affected by vibrations for a long time, which may cause the device connection to become unstable. In addition, the existing device cannot adjust the rigidity of the main stress points between the layers, making it difficult to adapt to more different environments.

[0014] The assembly method applicable to the above-mentioned component based on the external steel support multi-layer steel structure comprises the following steps:

[0015] S1. Pre-assembling the layer steel beams, fixing the plurality of layer steel beams in sequence from head to tail to form a rectangle, and fixing the head and tail joints by welding;

[0016] S2, main body assembly, welding one side of the plurality of first load-bearing steel beams to one side of the rectangle formed by the plurality of layer steel beams in step S1, and welding one side of the plurality of second load-bearing steel beams to one side of the rectangle formed by the plurality of layer steel beams in step S1;

[0020] Compared with the related art, the component and assembly method of the multi-layer steel structure based on the external steel support provided by the present invention has the following beneficial effects:

[0021] 1. The present invention provides a component and assembly method of a multi-layer steel structure based on an external steel support. In the specific use process, the steel structures between the multiple layers are connected by multiple limit plates and a clamping block. When connecting, it is only necessary to push the clamping block into the multiple limit plates, and fix the clamping block by multiple high-rigidity springs and multiple limit plates, so that the installation is more convenient, the removal is also faster, and the work efficiency is improved. The steel structure is connected with the multi-layer steel support steel structure by multiple oblique connection blocks, so that the steel structure can be more stable and safe after installation;

[0022] 2. The distance between the multiple second mounting plates and the multiple connecting blocks is changed by multiple threaded rods. At this time, the elastic force of the multiple high-rigidity springs between the multiple second mounting plates and the multiple connecting blocks can be changed. When the multiple threaded rods drive the distance between the multiple second mounting plates and the multiple connecting blocks to decrease, the elastic force of the multiple high-rigidity springs on the multiple limit plates increases. At this time, the variable distance of the clamping block in the limit plate is reduced, so that the interlayer connection rigidity of the device is greater, which can adapt to the environment of high-intensity vibration. When the multiple threaded rods increase the distance between the multiple second mounting plates and the multiple connecting blocks, the elastic force of the multiple high-rigidity springs on the multiple limit plates decreases. At this time, the variable distance of the clamping block in the limit plate is increased, so that the layer connection rigidity of the device is reduced. At this time, the device can adapt to the environment of low-intensity vibration. When the device is vibrated, the multiple high-rigidity springs absorb the stress generated by the vibration to avoid instability of the device due to vibration. Through the two adjustment methods, the device can achieve better connection effect when facing different environments, increase the applicability of the device, and change the connection rigidity of the main force points after the device is connected.

[0036] In the specific implementation process, Figure 1-Figure 10 As shown, the present invention provides a component and assembly method of a multi-layer steel structure based on an external steel support, including: a multi-layer support steel structure main body and a plurality of interlayer connection structures, wherein the upper and lower sides of the plurality of interlayer connection structures are fixedly connected to the inner two sides of the multi-layer support steel structure main body;

[0037] The interlayer connection structure includes: a mounting shell 1, a limit block 2, a first mounting plate 3 and a second mounting plate 4, the outer wall of the limit block 2 is fitted with the inner wall of the mounting shell 1, a limit hole 5 is provided on the limit block 2, and the cross-section of the limit hole 5 is rectangular, and a plurality of limit rods 6 are evenly arranged on the opposite sides of the first mounting plate 3 and the second mounting plate 4, the outer wall of the first mounting plate 3 is fitted with the inner wall of the mounting shell 1, a mounting column 7 is fixedly arranged on the first mounting plate 3, and a plurality of limit plates 8 are evenly and movably arranged on the side of the mounting column 7, and the plurality of limit plates 8 are arc-shaped, and a stiffness adjustment component is arranged on the outer side of the plurality of limit plates 8, one side of the interior of the multi-layer supporting steel structure body is fixedly connected to the side of the first mounting plate 3 away from the mounting column 7, and a clamping block 9 is arranged on the other side of the interior of the multi-layer supporting steel structure body, and the clamping block 9 extends into the plurality of limit plates 8, and the outer wall of the clamping block 9 is fitted with the inner wall of the plurality of limit plates 8.

[0038] It should be noted that the above-mentioned mounting shell 1 is made of high-strength steel, which can protect the internal structure when in use, and the limiting hole 5 opened on the above-mentioned limiting block 2 has a rectangular cross-section, which can limit the multi-layer supporting steel structure body when in use, so that the device can be more tightly connected, and the multi-layer steel structure body is limited so that the movement range of the multi-layer steel structure body is reduced, and the connection position is more accurate. The outer walls of the above-mentioned first mounting plate 3 and the second mounting plate 4 are in contact with the inner wall of the mounting shell 1, and the first mounting plate 3 is fixedly connected to the inner side of the mounting shell 1, so that the device is installed more tightly when in use. The multiple limiting rods 6 evenly arranged on the opposite sides of the first mounting plate 3 and the second mounting plate 4 can limit the movement of the second mounting rod 4 to a linear motion, making the device more stable. The above-mentioned multiple limiting plates 8 are arc-shaped, such as Figure 5 As shown, a plurality of limit plates 8 can form a semi-ellipsoid, and the above-mentioned locking block 9 is ellipsoidal, so that the plurality of limit plates 8 can fix the locking block 9 after closing, and a part of the lower end of the locking block 9 is cut off, so that the lower end of the locking block 9 is in contact with the mounting column 7, making the device connection and installation more stable and firm.

[0039] The stiffness adjustment component includes: multiple high-rigidity springs 10, multiple connecting blocks 11 and multiple threaded rods 12, one side of the multiple connecting blocks 11 is fixedly connected to the outer sides of the multiple limit plates 8, one side of the multiple high-rigidity springs 10 is fixedly connected to the side of the multiple connecting blocks 11 close to the second mounting plate 4, one side of the multiple high-rigidity springs 10 away from the multiple connecting blocks 11 is fixedly connected to the side of the second mounting plate 4 away from the first mounting plate 3, one side of the multiple threaded rods 12 is rotatably connected to the side of the second mounting plate 4 away from the multiple high-rigidity springs 10, one side of the multiple threaded rods 12 away from the second mounting plate 4 is threadedly connected to the first mounting plate 3, and a rotating block 13 is provided on the side of the multiple threaded rods 12 away from the second mounting plate 4, and an anti-slip coating 14 is provided on the outer sides of the multiple rotating blocks 13.

[0040] It should be noted that the above-mentioned multiple rotating blocks 13 can be used to more conveniently rotate the multiple threaded rods 12. When the multiple threaded rods 12 are rotated, since the threaded rods 12 are threadedly connected to the first mounting plate 3, and the first mounting plate 3 and the multiple limit plates 8 are fixedly connected to the inside of the mounting shell 1, when the multiple threaded rods 12 are rotated, the second mounting plate 4 will be driven to move linearly along the multiple limit rods 6, thereby adjusting the distance between the second mounting plate 4 and the multiple connecting blocks 11. When the distance between the second mounting plate 4 and the multiple connecting blocks 11 is reduced, the multiple high-rigidity springs 10 are squeezed to increase the deformation, and the pressure of the multiple high-rigidity springs 10 on the connecting block 11 is increased, so that the pressure of the multiple limit plates 8 on the locking block 9 is increased, making the device connection more tight, and at this time increasing the connection of the device Rigidity, adapt to the environment that requires high-rigidity connection. When the distance between the second mounting plate 4 and the multiple connecting blocks 11 increases, the deformation of the multiple high-rigidity springs 10 decreases. At this time, the pressure of the multiple limit plates 8 on the locking block 9 is reduced, so that the locking block 9 can be changed slightly within the multiple limit plates 8. At this time, facing the environment of high-frequency and mild vibration, it can absorb the stress generated by the vibration, so that the device can adapt to different environments, and the elastic force of the high-rigidity springs 10 behind the multiple limit plates 8 can be independently adjusted through the multiple threaded rods 12, so that the device can realize different adjustment schemes in more complex environments. For example, when a greater degree of support is needed in a certain direction, the threaded rod 12 in a certain direction can be adjusted to increase the rigidity in that direction, so that better support can be provided in that direction.

[0041] A plurality of mounting holes 15 are arranged on the side of the mounting column 7, and a mounting block 20 is arranged on one side of the plurality of limit plates 8 close to the mounting column 7. The plurality of mounting blocks 20 extend into the plurality of mounting holes 15 respectively, and the side walls of the plurality of mounting blocks 20 are rotatably connected to the side walls of the plurality of mounting holes 15 respectively, and a plurality of oblique connecting blocks 21 are evenly arranged on the outer side of the mounting shell 1, and one side of the multi-layer supporting steel structure body is fixedly connected to the outer sides of the plurality of oblique connecting blocks 21 respectively.

[0042] It should be noted that the above-mentioned rotating connection rotatably connects the mounting block 20 to the multiple mounting holes 15 through bolts, so that the multiple limit plates 8 can rotate around the connection with the multiple mounting holes 15, and the above-mentioned multiple oblique connecting blocks 21 can be connected to the multi-layer supporting steel structure, so that a more stable oblique structure can be formed, so that the stability and safety of the device are further improved.

[0043] The main body of the multi-layer supporting steel structure includes: multiple first load-bearing steel beams 16, multiple second load-bearing steel beams 17, multiple oblique column-connecting steel beams 18, and multiple level steel beams 19. The multiple level steel beams 19 are fixedly connected head to tail, and the multiple level steel beams form a rectangle. One side of the multiple first load-bearing steel beams 16 is fixedly connected to one side of the level steel beam 19, the side of the multiple first load-bearing steel beams away from the level steel beam 19 is fixedly connected to the side of the first mounting plate 3 away from the second mounting plate 4, one side of the multiple second load-bearing steel beams 17 is fixedly connected to one side of the multiple snap-fit ​​blocks 9, the side of the multiple second load-bearing steel beams 17 away from the multiple snap-fit ​​blocks 9 is fixedly connected to one side of the multiple level steel beams 19, the two sides of the multiple oblique column-connecting steel beams 18 are respectively fixedly connected to the outer sides of the multiple oblique connecting blocks 21, the cross-sections of the multiple first load-bearing steel beams 16 and the multiple second load-bearing steel beams 17 are rectangular, and the interiors of the multiple first load-bearing steel beams 16 and the multiple second load-bearing steel beams 17 are all set to be hollow.

[0044] It should be noted that the above-mentioned component materials used to form the main body of the multi-layer supporting steel structure are all high-strength steel. In actual use, the material can withstand greater pressure, making the device more secure and safer. The above-mentioned multiple oblique column connecting steel beams 18 make the device more secure and safer when subjected to lateral stress. The ends of the above-mentioned multiple oblique column connecting steel beams 18 are as follows: Fig. 9 As shown, the ends of the multiple oblique column-connected steel beams 18 can be engaged with the multiple oblique connecting blocks 21. At this time, the oblique column-connected steel beams 18 can be engaged and fixed with the multiple oblique connecting blocks 21 by means of bolts or the like, so that the multiple oblique column-connected steel beams 18 can more effectively fix the device. For the steel structure frame, the connection nodes between the above-mentioned multiple first load-bearing steel beams 16 and the multiple second load-bearing steel beams 17 are the main force-bearing connection points of the multi-layer steel structure. Therefore, installing the device here can better absorb stress and make the device connection effect better.

[0045] The assembly method applicable to the above-mentioned component based on the external steel support multi-layer steel structure comprises the following steps:

[0046] S1, pre-assembly of the layer steel beams, fixing multiple layer steel beams 19 in sequence from head to tail to form a rectangle, and fixing the head and tail joints by welding;

[0047] It should be noted that the size of the layer can be changed by increasing or decreasing the number of layer steel beams 19, so that the device can be used in various operations.

[0048] S2, main body assembly, welding one side of the plurality of first load-bearing steel beams 16 to one side of the rectangle formed by the plurality of layer steel beams 19 in step S1, and welding one side of the plurality of second load-bearing steel beams 17 to one side of the rectangle formed by the plurality of layer steel beams 19 in step S1;

[0049] S3, splicing adjustment, push the multiple snap-fit ​​blocks 9 set on one side of the plurality of second load-bearing steel beams 17 into the inside of the mounting shell 1 set on one side of the plurality of first load-bearing steel beams 16 respectively, when the multiple snap-fit ​​blocks 9 are in contact with the multiple limit plates 8 respectively, at this time, the multiple limit plates 8 will spread out around the side rotatably connected to the mounting column 7, at this time, the multiple high-rigidity springs 10 are in a compressed state, when the multiple snap-fit ​​blocks 9 enter the interior of the multiple limit plates 8 respectively, at this time, the multiple high-rigidity springs 10 provide elastic force, so that the multiple limit plates 8 are all closed, and the snap-fit ​​blocks 9 are fixed, at this time, the connection of the multiple first load-bearing steel beams 16 and the multiple second load-bearing steel beams 17 is completed;

[0050] S4, state adjustment. After the device connection is completed, the required state of the device is obtained through analysis. When the device is in an environment with large vibration, the device needs a high-rigidity connection to place the device apart. At this time, the multiple threaded rods 12 are rotated to reduce the distance between the multiple second mounting plates 4 and the multiple connecting blocks 11. At this time, the rigidity of the device connection is increased to resist large vibrations. When the device is in an environment with small vibrations, the multiple threaded rods 12 are rotated to increase the distance between the multiple second mounting plates 4 and the multiple connecting blocks 11, so that the elastic force generated by the multiple high-rigidity springs 10 is reduced. At this time, the multiple high-rigidity springs 10 absorb the stress generated by the small vibration, making the device connection more stable.

[0051] It should be noted that in the process of rigidity adjustment, it is necessary to ensure that the multiple limit plates 8 fix the locking block 9 and the locking block 9 will not detach from the multiple limit plates 8. At this time, on this basis, the deformation of the multiple high-rigidity springs 10 is adjusted to change the elastic force of the multiple high-rigidity springs 10. At this time, when the locking block 9 is displaced by vibration, the size of the elastic force of the multiple high-rigidity springs 10 that needs to be overcome changes. When a larger elastic force needs to be overcome, the connection rigidity of the device is larger, and when a smaller elastic force needs to be overcome, the connection rigidity of the device is smaller. The larger connection rigidity can withstand higher-intensity vibrations, and the smaller connection rigidity can directly absorb the stress generated by smaller-intensity vibrations, which can extend the service life of the device and increase the scope of use of the device, making the device safer to use.

[0052] S5. Reinforce the connection of the device. After the device is adjusted, one end of the plurality of oblique column connecting steel beams 18 is connected to the outer sides of the plurality of oblique connecting blocks 21, so that the device forms a more solid connection relationship.
