Description

Technical Field

[0001] The invention relates to the technical field of earthquake-resistant buildings, and in particular to an earthquake-resistant building steel structure using a viscous damper. Background Art

[0002] Viscous dampers are a type of structural control device widely used in earthquake-resistant design. They are usually used in building steel structures to increase the energy dissipation capacity of the structure and reduce the vibration amplitude of the structure during earthquakes. Working principle: Viscous dampers use the internal friction generated by viscous materials when the structure vibrates to consume and disperse seismic energy. When the structure is subjected to an earthquake, the viscous damper absorbs and disperses the vibration energy through the relative movement of the oil, thereby reducing the vibration amplitude and acceleration response of the structure. Generally, the viscous damper is welded to the surface of the steel frame through metal plates and steel bars, and the viscous damper is fixedly connected to the steel frame by pouring concrete.

[0003] The earthquake-resistant building steel structure of the viscous damper of the prior art is generally welded between the ear plate and the metal plate. In order to enhance the stability of the steel structure, a number of steel bars are welded on the bottom surface of the metal plate, and one end of the multiple steel bars is inserted into the interior of the steel frame. The steel bars and the steel frame are welded to each other to enhance the firmness. Finally, the viscous damper steel structure and the steel frame are integrated by concrete pouring to achieve the installation of the viscous damper. However, since the viscous damper building steel structure of the prior art requires the fixed steel bars to be inserted into the woven steel frame, and the steel bars and the steel frame are welded to each other by welding, it is necessary to adjust the welding angle during the welding process in order to weld and fix all the steel bars, which makes the installation process more troublesome. Summary of the invention

After the correspondence is completed, the base plate 10 is moved downward so that the connecting steel bar 8 installed on the top surface of the positioning plate 6 is inserted into the inner wall of the sleeve plate 12. At this time, the connecting steel bar 8 inserted into the sleeve plate 12 will be inserted into the docking hole 11 opened on the surface of the base plate 10 along the sleeve plate 12, and because the connecting steel bar 8 has a certain length, the connecting steel bar 8 inserted into the docking hole 11 will pass through the top of the docking hole 11, thereby realizing the rapid assembly of the building steel structure. Embodiment 2

[0023] Based on the above Example 1, please refer to Figure 1-Figure 4 The docking assembly includes a base plate 10, a docking hole 11 is provided on the top surface of the base plate 10, a sleeve plate 12 is installed on the bottom surface of the base plate 10, a limiting groove 13 is provided on the top surface of the sleeve plate 12, an ear plate 14 is installed on the top surface of the limiting groove 13, and the base plate 10 is installed on the inner wall of the limiting groove 5.

[0024] There are a plurality of docking holes 11, which correspond one-to-one to the connecting steel bars 8; there are a plurality of sleeve plates 12, which correspond one-to-one to the connecting holes; the inner wall of the docking hole 11 is movably plugged into the outer surface of the connecting steel bars 8, and the inner wall of the sleeve plate 12 is movably contacted with the outer surface of the connecting steel bars 8.

[0025] There are two limiting grooves 13 equidistantly distributed on the top surface of the bottom plate 10 , and an ear plate 14 is correspondingly distributed on the inner wall of each limiting groove 13 , and the ear plate 14 and the bottom plate 10 are welded to each other.

[0026] The rotating shaft 15 is installed on the inner wall of the ear plate 14 , the outer surface of the rotating shaft 15 is movably rotatably connected to the inner walls of the two ear plates 14 , the outer surface of the rotating shaft 15 is movably rotatably connected to the inner wall of the rotating plate 16 , and the rotating plate 16 is fixedly connected to the viscous damper 17 .

[0027] When the cement is completely air-dried, the connecting steel bar 8 is trimmed so that the top of the connecting steel bar 8 is at the same height as the top surface of the bottom plate 10. After trimming, the connecting steel bar 8 and the bottom plate 10 are welded to each other so that the two are fixedly connected. After welding, the two ear plates 14 are placed in the limiting grooves 13, and the ear plates 14 and the bottom plate 10 are also fixedly connected by welding. After welding, the rotating plate 16 installed on the surface of one side of the viscous damper 17 is inserted between the two ear plates 14. After the insertion is completed, the rotating shaft 15 is inserted into the inner wall of the ear plate 14, and the rotating shaft 15 is inserted into the inner wall of the rotating plate 16 to achieve the installation of the viscous damper 17.

[0028] It should be noted that the number of structures can be adjusted according to actual needs.

[0029] During operation, when it is necessary to install the earthquake-resistant structure of the building, the first steel bar 1 is arranged on the ground. When arranging, the positioning plate 6 is sleeved on the outer surface of the first steel bar 1 through the sleeve hole 9, and the positioning plate 6 and the outer surfaces of the two first steel bars 1 are sleeved with each other. After the sleeve connection is completed, several second steel bars 2 are installed on the ground, and the inner wall of the second steel bar 2 is in contact with the top surface of the first steel bar 1. When the first steel bar 1 and the second steel bar 2 are both installed, the stirrup 3 is sleeved on the outer surface of the first steel bar 1 and the second steel bar 2. After the sleeve connection is completed, the positioning plate 6 is pushed to move upward along the first steel bar 1. When the positioning plate 6 moves to the high point of the first steel bar 1, the bottom end surface of the positioning plate 6 and the top surface of the stirrup 3 are in contact with each other, thereby realizing the adjustment of the height of the positioning plate 6. When the adjustment is completed At this time, the first steel bar 1, the second steel bar 2 and the stirrup 3 are fixedly connected by welding, and the three are made into a whole by welding. After welding is completed, the positioning plate 6 and the stirrup 3 are fixedly welded. After welding is completed, the base plate 10 is picked up, and the sleeve plate 12 installed on its bottom surface is made to correspond one by one with the connecting steel bar 8 installed on the top surface of the positioning plate 6. After the correspondence is completed, the base plate 10 is moved downward so that the connecting steel bar 8 installed on the top surface of the positioning plate 6 is inserted into the inner wall of the sleeve plate 12. At this time, the connecting steel bar 8 inserted into the sleeve plate 12 will be inserted into the docking hole 11 opened on the surface of the base plate 10 along the sleeve plate 12, and because the connecting steel bar 8 has a certain length, the connecting steel bar 8 inserted into the docking hole 11 will pass through the top of the docking hole 11, thereby realizing the rapid assembly of the building steel structure.

[0030] When the assembly is completed, the steel frame is surrounded by a baffle. When the surrounding is completed, concrete is poured into the baffle so that the height of the concrete is consistent with the top surface height of the bottom plate 10. After the pouring is completed, the height and horizontal state of the bottom plate 10 are adjusted before the concrete dries. When the concrete is air-dried, a cement wall 4 will be formed on the outer surface of the steel frame. Because the height of the bottom plate 10 is consistent with that of the cement, the concrete will form a limiting groove 13 and surround the bottom plate 10 after the concrete is air-dried. When the cement is air-dried, the connecting steel bar 8 is trimmed so that the top of the connecting steel bar 8 is consistent with the bottom plate. The top surface height of 10 is consistent. After trimming, the connecting steel bar 8 and the base plate 10 are welded to each other by welding to fix the two. After welding, the two ear plates 14 are placed in the limiting groove 13, and the ear plates 14 and the base plate 10 are also fixedly connected by welding. After welding, the rotating plate 16 installed on the surface of one side of the viscous damper 17 is inserted between the two ear plates 14. After the insertion is completed, the rotating shaft 15 is inserted into the inner wall of the ear plate 14, and the rotating shaft 15 is inserted into the inner wall of the rotating plate 16 to realize the installation of the viscous damper 17.

[0031] When the building is subjected to vibration during use, the viscous damper 17 will absorb the vibration or shaking force, and reduce the shaking degree of the building through the structure of the viscous damper 17 itself. The viscous damper 17 is fixedly connected to the ear plate 14 and the bottom plate 10 through the rotating plate 16. After the viscous damper 17 buffers the force, a part of the force will still be transmitted to the bottom plate 10 through the ear plate 14. Because the bottom plate 10 is on the inner wall of the limiting groove 5 and is fixedly connected to the connecting steel bar 8 by welding, the bottom plate 10 will not loosen or shake under pressure at this time. The bottom plate 10 is rooted in the inner wall of the cement wall 4 through the connecting steel bar 8 and the sleeve plate 12, so the excess force will be absorbed by the cement wall 4 at this time. In addition, because a number of cross plates 7 are installed on the top surface of the positioning plate 6, the cross plate 7 will increase the contact area with the cement. At this time, the force transmitted to the positioning plate 6 will also be absorbed by the cement wall 4, thereby improving the installation firmness of the viscous damper 17.
