Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to an earthquake-resistant steel structure. Background Technology

[0002] Steel structures are structures formed by assembling and connecting steel materials, and are one of the main types of building structures. In steel structure buildings, the connection methods used to connect the steel materials are crucial, as these methods enable the building structure to perform load-bearing and earthquake resistance functions.

[0003] However, in practical use, the beam-column connections of traditional steel structures are usually fixed by simple bolts. When vibration occurs, lateral and longitudinal vibrations will occur, causing the steel structure to move accordingly. In the event of lateral or longitudinal shear movement, the bolts of the traditional fixed structure can be easily cut off, resulting in the breakage of the connection structure and affecting the seismic performance of the device. At the same time, the traditional connection and support structure is also relatively simple. Once the connection point is detached, the entire device can easily be separated, and its structural safety redundancy is small. Utility Model Content

[0004] The purpose of this invention is to provide an earthquake-resistant steel structure that solves the problems of existing traditional connection methods that easily lead to bolt breakage and detachment, and the lack of redundant fixed support structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an earthquake-resistant steel structure, including a support column, an mounting plate, and a fixing frame. The mounting plate is installed on one side of the support column, and a fixing frame is fixedly connected to the top of the mounting plate on the side away from the support column. A support beam assembly is installed through the inside of the fixing frame. A shock-absorbing rod is installed at the bottom of the fixing frame at an incline, and a tie rod is installed at the top of the fixing frame at an incline. A sliding block is rotatably connected to the end of the shock-absorbing rod and the tie rod near the support beam assembly.

[0006] The top and bottom of the fixed frame are connected by connecting bolts, and a fixing bolt is installed through the center of the side wall of the fixed frame. The fixing bolt and the connecting bolt are threaded with fixing nuts at the end of the fixed bolt and the outer wall of the fixed frame.

[0007] The support beam assembly includes a center plate and a bonding plate. The bonding plate is fixedly connected to the top and bottom of the center plate. Multiple vertical holes are opened at the center of the center plate, and multiple horizontal holes are opened on both sides of the center plate.

[0008] The end of the shock absorber rod near the mounting plate is tilted and rotatably connected to the fixing plate on the side away from the fixing frame. The interior of the fixing plate is connected and fixed to the mounting plate by bolts.

[0009] Preferably, the mounting plate has multiple mounting holes arranged in an array inside its sidewall, and the internal bolts of the fixing plate are threadedly connected to the inside of the mounting holes for fixation. Both sides of the mounting plate are inclined towards one side of the fixing frame in an U-shape.

[0010] Preferably, the end of the pull rod away from the support beam assembly is rotatably connected to a connecting plate, and the interior of the connecting plate is fixedly connected to the side wall of the support column by bolts. The end of the pull rod near the support beam assembly is internally threaded with an extension rod, and the extension rod is rotatably connected to the sliding block.

[0011] Preferably, the fixing bolt passes through a vertical hole inside the center plate, the vertical hole and the outer wall of the fixing bolt are connected to each other, and the two sides of the vertical hole are tightly fitted with the outer wall of the fixing frame. The top and bottom of the vertical hole are spaced apart from the side wall of the fixing bolt and are elliptical in shape.

[0012] Preferably, the support column is prismatic, and bolts are installed through the mounting holes on the top and bottom sidewalls of the mounting plate. The interior of the mounting plate is fixedly threaded to the sidewalls of the support column by the bolts.

[0013] Preferably, the sliding block has a groove on the side near the support beam assembly that slides against the bonding plate, and a pressing bolt is threaded into the end of the sliding block away from the fixed frame. One end of the pressing bolt passes through the interior of the sliding block and is in contact with the bonding plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The external fixing frame further restricts the support beam assembly. Since the horizontal holes and connecting bolts are interconnected, when vibration occurs, the horizontal sliding of the bonding plate can cause the horizontal holes to move accordingly, resulting in relative movement between the horizontal holes and the connecting bolts. This prevents direct impact on the connecting bolts and thus avoids breakage. Similarly, when the center plate shakes vertically, it can also cause the vertical holes to move, resulting in relative movement between the vertical holes and the fixing bolts. This also prevents direct impact on the fixing bolts and thus avoids breakage. Furthermore, since one end of both the center plate and the bonding plate is inside the fixing frame, even if the fixing bolts and connecting bolts break, the support beam assembly can be effectively prevented from falling directly, effectively resisting vibration.

[0016] 2. The support beam assembly is connected to the fixed frame by the through-hole connection of the fixing bolts and connecting bolts. During use, one end of the shock absorber rod can rotate and connect with the sliding block, which in turn allows the sliding block to slide with the bonding plate. This allows the connection position of the sliding block to be adjusted. When the bonding plate vibrates, the vibration is transmitted to the shock absorber rod at the bottom through the sliding block, and then absorbed by the shock absorber rod. During use, the connection position between the fixed plate and the mounting plate can be easily adjusted to adjust the connection position of the shock absorber rod. The bonding plate can also be pulled by the tie rod at the top of the fixed frame to prevent the bonding plate from falling to the bottom during vibration, thus assisting in the support and fixation.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The earthquake-resistant steel structure shown includes a support column 1, a mounting plate 2, and a fixing frame 3. The mounting plate 2 is installed on one side of the support column 1. A fixing frame 3 is fixedly connected to the top of the mounting plate 2 on the side away from the support column 1. A support beam assembly 4 is installed through the interior of the fixing frame 3. A shock-absorbing rod 5 is installed at an angle at the bottom of the fixing frame 3, and a tie rod 6 is installed at an angle at the top of the fixing frame 3. Sliding blocks 7 are rotatably connected to the ends of both the shock-absorbing rod 5 and the tie rod 6 near the support beam assembly 4. Connecting bolts 302 are installed through the top and bottom of the interior of the fixing frame 3. A fixing rod is installed through the center of the side wall of the fixing frame 3. The fixing bolt 301 and the connecting bolt 302 are threaded with fixing nuts 303 at one end of the bolts passing through the outer wall of the fixing frame 3; the support beam assembly 4 includes a center plate 401 and a bonding plate 402. The top and bottom of the center plate 401 are fixedly connected to the bonding plate 402. The center of the center plate 401 has multiple vertical holes 403 and multiple horizontal holes 404 on both sides of the center plate 401; the end of the shock absorber 5 near the mounting plate 2 is tilted and rotatably connected to the fixing plate 501 away from the fixing frame 3. The interior of the fixing plate 501 is connected and fixed to the mounting plate 2 by bolts.

[0027] like Figure 3 , Figure 4 As shown, the mounting plate 2 has multiple mounting holes 201 arranged in an array inside the side wall. The bolts inside the fixing plate 501 are threadedly connected to the inside of the mounting holes 201. Both sides of the mounting plate 2 are inclined to one side of the fixing frame 3 in a U-shape. The support column 1 is prismatic. Bolts are installed through the mounting holes 201 on the top and bottom side walls of the mounting plate 2. The inside of the mounting plate 2 is threadedly connected to the side wall of the support column 1 by bolts.

[0028] like Figure 2 , Figure 5 As shown, the end of the tie rod 6 away from the support beam assembly 4 is rotatably connected to a connecting plate 601. The interior of the connecting plate 601 is fixedly connected to the side wall of the support column 1 by bolts. The end of the tie rod 6 near the support beam assembly 4 is internally threaded with an extension rod. The extension rod is rotatably connected to the sliding block 7. The tie rod 6 at the top of the fixed frame 3 can also pull the bonding plate 402, thereby preventing the bonding plate 402 from falling to the bottom during vibration, thus assisting in the support and fixation, achieving seismic resistance and preventing structural detachment.

[0029] like Figure 3 , Figure 4As shown, the fixing bolt 301 passes through the vertical hole 403 inside the center plate 401. The vertical hole 403 and the outer wall of the fixing bolt 301 are connected and interlocked. The two sides of the vertical hole 403 are tightly fitted to the outer wall of the fixing frame 3. The top and bottom of the vertical hole 403 are spaced apart from the side wall of the fixing bolt 301 and are elliptical. This allows the horizontal hole 404 and the connecting bolt 302 to move relative to each other, thereby avoiding direct impact on the connecting bolt 302 and causing it to break. At the same time, when the center plate 401 is vertically shaken, it can also drive the vertical hole 403 to move, thereby allowing the vertical hole 403 and the fixing bolt 301 to move relative to each other, avoiding direct impact on the fixing bolt 301 and causing it to break.

[0030] like Figure 1 , Figure 2 As shown, the sliding block 7 has a groove inside on the side near the support beam assembly 4 that slides against the bonding plate 402. The end of the sliding block 7 away from the fixed frame 3 is internally connected with a pressing bolt 701. One end of the pressing bolt 701 passes through the interior of the sliding block 7 and is in contact with the bonding plate 402, which allows one end of the shock absorber 5 to be rotatably connected to the sliding block 7, thereby allowing the sliding block 7 and the bonding plate 402 to slide against each other, thus allowing the connection position of the sliding block 7 to be adjusted. The position of the sliding block 7 can be fixed by rotating the pressing bolt 701. At the same time, when the bonding plate 402 vibrates, the vibration can be transmitted to the bottom shock absorber 5 through the sliding block 7, and then the shock absorber 5 absorbs the vibration.

[0031] During use, the support beam assembly 4 can be easily inserted into the fixed frame 3, allowing the connecting bolt 302 to pass through the horizontal hole 404 and the fixing bolt 301 to pass through the vertical hole 403. The mutually perpendicular fixing bolt 301 and connecting bolt 302 thus limit the center plate 401 and the bonding plate 402, preventing movement of the support beam assembly 4. The external fixed frame 3 further restricts the support beam assembly 4. Furthermore, since the horizontal hole 404 and the connecting bolt 302 are interpenetrating, the horizontal sliding of the bonding plate 402 during vibration can move the horizontal hole 404. The movement of the horizontal hole 404 and the connecting bolt 302 causes relative movement, thus preventing direct impact on the connecting bolt 302 and potential breakage. Simultaneously, the vertical movement of the center plate 401 also causes the vertical hole 403 to move relative to the fixing bolt 301, preventing direct impact on the fixing bolt 301 and potential breakage. Furthermore, since one end of both the center plate 401 and the bonding plate 402 is inside the fixing frame 3, even if the fixing bolt 301 and the connecting bolt 302 break, the support beam assembly 4 can be effectively prevented from falling directly, effectively resisting vibration.

[0032] During use, the support beam assembly 4 and the fixed frame 3 are connected and fixed by the through-hole connection of the fixing bolts 301 and the connecting bolts 302. At the same time, one end of the shock absorber 5 can be rotated and connected to the sliding block 7, and then the sliding block 7 can slide against the bonding plate 402, so that the connection position of the sliding block 7 can be adjusted. Then, the position of the sliding block 7 can be fixed by rotating the clamping bolt 701. When the bonding plate 402 vibrates, the vibration can be transmitted to the shock absorber 5 at the bottom through the sliding block 7, and then the shock absorber 5 can absorb the vibration. At the same time, the connection position of the fixed plate 501 and the mounting plate 2 can be easily adjusted to adjust the connection position of the shock absorber 5. The bonding plate 402 can also be pulled by the tie rod 6 at the top of the fixed frame 3, so as to prevent the bonding plate 402 from falling to the bottom during vibration, thus assisting in the support and fixation, achieving seismic resistance and preventing structural detachment.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
