Description

Technical Field

[0002] Steel structure is a type of building structure mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, etc. It is one of the main building structure types of existing buildings and is widely used. In the main part of the steel structure, the support part and the top beam are generally connected by bolts or welding. This connection method has high strength, but lacks a buffering effect. When subjected to crosswind or lateral vibration, the overall steel structure has a tendency to lean sideways. At this time, the connection nodes of the steel structure will instantaneously bear excessive force. When the bolts are subjected to excessive instantaneous force, wear is likely to occur, causing the connection to become loose; and when the welded joints are subjected to excessive instantaneous force, cracking is likely to occur.

[0003] In summary, the existing connection method is likely to cause too high rigidity at the connection, so that the connection is easily damaged when suddenly subjected to excessive bearing capacity, affecting the firmness of the connection. Summary of the Invention

[0031] To make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention in conjunction with the drawings of the specification.

[0032] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] Secondly, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0034] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0035] Referring to Figure 1-9 , one embodiment of the present invention provides an assembled flexible connection device. The device at least includes a fixing frame 1 (the first connection part) and two connection blocks 2 (the second connection part) located on the fixing frame 1. Specifically:

[0036] The fixing frame 1 has a longitudinally extended structure. The connection blocks 2 are distributed on the upper and lower parts of the fixing frame 1. The connection blocks 2 are slidably arranged transversely on the fixing frame 1, and the sliding direction is parallel to the Figure 3 arrow direction in Figure 3 . As shown in the Figure 1 viewpoint, shock-absorbing blocks 3 (flexible connection parts) made of rubber material are abutted between the front and rear sides of each connection block 2 and the fixing frame 1. Expansion capsules 4 are also abutted between the front and rear sides of each connection block 2 and the fixing frame 1. Oil pipes are connected between the expansion capsules 4. To keep the structure shown in the figure simplified, the oil pipes are not shown in the Figure 9 viewpoint. For details, reference can be made to the

[0037] When this device completes the connection between the support part and the top beam of a building, the fixing frame 1 is welded to the support part, and the upper and lower vertices at the end of the top beam are respectively welded and connected to the two connection blocks 2. At this time, the connection between the top beam and the support part is completed. Specifically, as shown in Figure 7-8 , when the building is horizontally stressed, horizontal mutual forces are formed between the upper and lower vertices at the end of the top beam and the support part of the building respectively, that is, the connection blocks 2 are horizontally stressed on the fixing frame 1, so that the connection blocks 2 squeeze the shock-absorbing blocks 3 on the fixing frame 1. Due to the flexible characteristics of the shock-absorbing blocks 3, they can undergo a small amount of contraction when being oppressed, enabling the connection blocks 2 to move slightly horizontally on the fixing frame 1. Thus, the effect of buffering the mutual forces between the connection blocks 2 and the fixing frame 1 through the shock-absorbing blocks 3 is achieved, avoiding the phenomenon that the force is directly and instantaneously applied to the connection between the support part and the top beam, and reducing the phenomenon of stress damage at the connection between the two.

[0038] Further, Figure 9 As shown, Figure 1 is a schematic diagram of the relative positions and movement principles between multiple structures in the direction indicated by the arrow in. During the above movement process, for the role played by the expansion bladder 4, refer to Figure 9 the schematic diagram of the principle shown. Here, Figure 9 in the perspective view, the expansion bladders 4 on the left and right sides of the connecting block 2 near the upper part are respectively defined as the first expansion bladder and the second expansion bladder, and the expansion bladders 4 on the left and right sides of the connecting block 2 near the lower part in the perspective view are defined as the third expansion bladder and the fourth expansion bladder. Both of them are filled with hydraulic oil. The two connecting blocks 2 distributed up and down are defined as the upper connecting block and the lower connecting block here. Specifically, the first expansion bladder and the fourth expansion bladder are connected by a oil pipe, which is shown as the dark blue line in the figure. The second expansion bladder and the third expansion bladder are also connected by a oil pipe, which is shown as the green line in the figure. As Figure 9 shown, after the two vertices at the end of the top beam are fixedly connected to the two connecting blocks 2, when the top beam and the support part are stressed against each other, for example, during the process of the top beam forming a deviation trend due to the load, when the vertex at the upper part of the top beam is excessively squeezed to the left, the top beam forms a slight swing to the upper left in the perspective view, and at this time, the upper connecting block squeezes the first expansion bladder to the left on the fixing frame 1. At this time, after the first expansion bladder is excessively compressed, the hydraulic oil in it will be squeezed into the fourth expansion bladder, causing the fourth expansion bladder to expand, thereby squeezing the lower connecting block to the left, so that the lower connecting block will also shift slightly to the left on the fixing frame 1, so as to keep the upper and lower two vertices at the end of the top beam shift to the left at the same time, so as to achieve the effect of "forcing the top beam to be pulled straight", preventing the top beam from tilting excessively relative to the original installation position, so as to maintain the stability of the top beam on the support part;

[0039] Based on this, similarly, for example, when the vertex at the lower part of the top beam is stressed and squeezed to the left, according to the above principle, the upper and lower vertices of the top beam will also shift to the left; when any vertex at the upper and lower parts shifts to the right, the two vertices will shift to the right at the same time; this setting method of intercommunication between multiple expansion bladders 4 effectively ensures the stable effect of the top beam when resisting lateral forces, thereby ensuring the stability of the entire building when resisting cross winds or lateral forces.

[0040] Further, a flow guide tube 7 (blocking part) is also connected in series in the above oil pipe. When the hydraulic oil flows, it passes through the flow guide tube 7. Refer to Figure 4-6 . A through port 8 for the hydraulic oil to pass through is constructed on the inner diameter of the flow guide tube 7. A blocking member 9 which is of a sealing plate structure slides axially along the flow guide tube 7. A return spring 10 is connected between the blocking member 9 and the inner wall of the flow guide tube 7 to keep the blocking member 9 covering the through port 8 in the normal state. A flow limiting port 11 is constructed on the blocking member 9 for the hydraulic oil to pass through. The diameter of the flow limiting port 11 is smaller than the inner diameter of the oil pipe;

[0041] Based on this, as Figure 9 shown, for example, when the upper connecting block slowly squeezes the first expansion bladder and until the extrusion is excessive, when the oil flows into the fourth expansion bladder during this process, due to the restrictive effect of the flow-limiting orifice 11, the oil flows slowly, resulting in a slower expansion speed of the fourth expansion bladder. This effect enables the device not to immediately "straighten" the roof beam when the entire roof beam is subjected to a small lateral force. At this time, the shock-absorbing block 3 is allowed to fully exert its buffering effect;

[0042] According to the above, for example, when the entire steel building is subjected to a strong crosswind, at this time, the roof beam will quickly receive a large lateral force in a short time. At this time, if the upper connecting block instantaneously forms a rapid and excessive extrusion on the first expansion bladder, the flow pressure of the oil in the pipe is large. When the oil passes through the blocking member 9, it will forcefully push the blocking member 9 away from the through port 8, directly opening the through port 8. At this time, the oil directly flows rapidly in the pipeline through the through port 8. At this time, it is manifested as the rapid expansion of the fourth expansion bladder to complete the "forced straightening" effect of the roof beam;

[0043] This design effect of the blocking member in this device enables the entire building to, while buffering between structures when subjected to a large lateral tilt, also quickly correct the offset between structures, controlling the movement amplitude during the buffering between structures within a certain range, thereby ensuring the stability of the structure. When the building is subjected to a small lateral tilt, it can fully exert the buffering effect of this device, thus taking into account the actual use effect.

[0044] Furthermore, as Figure 1-3 shown, for the actual shape design of the fixing frame 1, one side of the fixing frame 1 is provided with a concave region, which is defined as the receiving area 5 here. Clamping cavities 6 are formed on both sides of the receiving area 5, and the expansion bladder 4 is arranged in the clamping cavities 6. This shape layout can ensure the compact effect of the entire device, thereby facilitating the installation of the device between steel structures;

[0045] In addition, a part of the connecting block 2 here is located within the receiving area 5. When the roof beam is connected to the connecting block 2, it is specifically connected to this part, enabling the top end of the roof beam to extend into the receiving area 5. As Figure 7 and Figure 8 shown, this setting effect enables the inner walls on both sides of the receiving area 5 to provide a lateral auxiliary support effect for the roof beam, preventing the roof beam from forming a lateral swaying trend, thereby further enhancing the stability of the roof beam.

[0046] It should be understood that, in the development of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without undue experimentation, the development efforts will be a routine task of design, manufacturing, and production.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
