Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to an earthquake-resistant building steel structure. Background Art

[0002] In seismically active areas, earthquake-resistant structural engineering plays a crucial role in disaster reduction. Earthquake damage investigations and studies have shown that earthquake disasters resulting in significant casualties often exhibit a dual mechanism: on the one hand, the enormous energy released by high-magnitude earthquakes, and on the other hand, the systematic failure of numerous non-seismically fortified structures. These structures experience brittle failure under strong earthquakes, typically manifesting as a pancake-like, continuous collapse. The resulting ruins often form dense piles, significantly reducing the living space available to trapped personnel.

[0003] In modern earthquake-resistant buildings, steel structural systems, with their excellent mechanical properties, have become an important technical means to enhance the seismic resistance of buildings. However, in actual engineering applications, the commonly used rigid connection method has significant limitations: First, when subjected to strong earthquakes, steel structures may suffer local damage or even overall instability due to their inability to effectively dissipate external energy. This non-ductile failure characteristic will sharply reduce the reliability of the building. Second, when there are connection defects between the main structure and the maintenance wall, the dynamic coupling effect between different structural systems will significantly amplify the structural response, potentially triggering catastrophic resonance. Insufficient node connection strength will lead to an increase in the structural acceleration response. This dynamic amplification effect not only accelerates structural fatigue damage, but also threatens the safety of people inside the building. Summary of the Invention

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-12 As shown, an earthquake-resistant building steel structure disclosed in this technical solution includes two parallel main frame beams 1 and a plurality of support beams 2. The main frame beams 1 are arranged in a V-shape, and the ends of the plurality of support beams 2 are respectively mounted on different main frame beams 1. The support beams 2 are fixedly connected to the main frame beams 1 by plug-in bolts 3.

[0040] Both ends of the main frame beam 1 are movably connected to the wall mounting plates 4, and the wall mounting plates 4 are connected to the wall through fastening screws 5;

[0041] The lower side of the main frame beam 1 is connected to a buffer member 6, and both ends of the buffer member 6 are hinged to the main frame beam 1 through a rotating frame 7 and a rotating plate 8. The rotating frame 7 is fixedly connected to the main frame beam 1;

[0042] The upper end of the buffer member 6 is fixedly connected to the main frame beam 1 through the support rod 9.

[0043] The top of the main frame beam 1 is fixedly connected by a reinforcing angle steel 10, and the reinforcing angle steel 10 is fixedly connected to the main frame beam 1 by welding. The reinforcing angle steel 10 is made of high-strength steel, so that when the staff installs the device, the staff first connects the two main frame beams 1 through the reinforcing angle steel 10. At this time, laser welding can improve the connection strength between the main frame beam 1 and the reinforcing angle steel 10.

[0044] The main frame beam 1 and the supporting beam frame 2 constructed of high-strength steel improve the earthquake resistance and can increase the connection strength between the main frame beam 1 and the wall. In the event of an earthquake, the main frame beam 1 is tightly connected to the wall, improving the earthquake resistance of the entire house.

[0045] Furthermore, a positioning groove 11 is provided on the main frame beam 1, and a positioning block 12 is threadedly connected to the plug bolt 3, and the positioning block 12 can be embedded in the positioning groove 11. Here, the positioning block 12 is integrally provided with the support beam 2, that is, the plug bolt 3 passes through the support beam 2 and the positioning block 12 at the same time. The coordinated use of the positioning block 12 and the positioning groove 11 can make the connection strength and connection accuracy of the device higher.

[0046] Furthermore, a shock-absorbing rubber pad 13 is installed on the wall-facing side of the wall mounting plate 4. A fastening screw 5 connection system provides rigid anchoring of the main frame beam 1 to the building's load-bearing wall. The shock-absorbing rubber pad 13 is placed at the contact interface, forming a composite connection interface that combines rigid fixation with flexible cushioning. This dual protection mechanism not only ensures the static stability of the structural connection but also isolates the vibration transmission of seismic loads through the energy dissipation of the damping material, thereby enhancing the overall seismic resistance of the device.

[0047] Furthermore, the buffer member 6 includes a buffer frame 61, which is fixedly connected to the support rod 9. A high-strength fixed connection is required here. A fixed plate 62 is provided inside the buffer frame 61. The fixed plate 62 is vertically arranged. A plurality of spring telescopic rods 63 are fixedly connected to the left and right sides of the fixed plate 62. The ends of the spring telescopic rods 63 on both sides away from the fixed plate 62 are connected to a buffer frame 64. The buffer frame 64 passes through the buffer frame 61 and is hinged to the rotating piece 8. The setting of the fixed plate 62 is to facilitate the connection of the spring telescopic rods 63.

[0048] A lap plate 65 is provided on both sides of the fixed plate 62, a plurality of spring telescopic rods 63 are connected to the lap plate 65, a buffer frame 64 is connected to the lap plate 65, a T-slot 66 is provided on the side surface inside the buffer frame 64, and the lap plate 65 is provided with a T-block 67, which is used in conjunction with the T-slot 66. The T-block 67 can slide in the T-slot 66, and the width of the T-slot 66 gradually decreases from one end close to the T-block 67 to the end away from the T-block 67.

[0049] When the main frame beam 1 is subjected to an impact force, the main frame beam 1 may be deformed. At this time, the buffer frame 64 connected to the main frame beam 1 begins to move into the buffer frame 61. The buffer frame 61 is fixedly connected to the top of the main frame beam 1 through the support rod 9, so the buffer frame 61 is in a stationary state. When the buffer frame 64 moves in the buffer frame 61, the buffer frame 64 is subjected to two forces:

[0050] The first is the spring force brought to the buffer frame 64 by the spring telescopic rod 63, which can buffer the impact force received by the main frame beam 1. The second is the sliding friction force received by the T-block 67 in the T-slot 66. Here, the T-block 67 is made of high-resistance rubber material, and the wedge-shaped design of the T-slot 66 can make the T-block 67 gradually compressed when sliding in the T-slot 66, and resistance and sliding friction will be generated at this time, which can perform secondary buffering of the impact force received by the main frame beam 1, thereby improving the seismic resistance of the main frame beam 1.

[0051] Furthermore, several reinforcing ribs 14 are installed between the support beams 2. The reinforcing ribs 14 and the support beams 2 are arranged crosswise, and several reinforcing ribs 14 are arranged in parallel. The reinforcing ribs 14 are inserted through the support beams 2. The ends of the reinforcing ribs 14 are fixed by fixing assemblies 15. The fixing assemblies 15 include positioning plates 151 and positioning screws 152. The positioning screws 152 are threadedly connected to the support beams 2. The ends of the reinforcing ribs 14 are provided with slots 154. The positioning plates 151 are provided with blocks 153. The slots 155 cooperate with the blocks 153.

[0052] Insert the positioning block 12 on the support beam 2 into the positioning groove 11 of the main frame beam 1, and then quickly install the support beam 2 by plugging in the bolts 3. At this time, the installation of the support beam 2 is completed. After the reinforcement rib 14 is inserted into the plug-in hole of the support beam 2, one end of the reinforcement rib 14 is fixedly connected with the plug-in bolt 3, and the other end of the reinforcement rib 14 needs to first insert the block 153 on the positioning plate 151 into the slot 154 in the reinforcement rib 14. At the same time, the positioning plate 151 can be fixedly connected to the reinforcement rib 14 through the positioning screw 152. At this time, the installation of the reinforcement rib 14 is completed.

[0053] Furthermore, the fastening screw 5 includes a fastening screw 51, which has a compression groove 52 formed along its axial direction, and a plurality of locking cavities 53 formed on the fastening screw 51. The locking cavities 53 are linearly arranged along the axial direction of the fastening screw 51;

[0054] A locking rod 54 is inserted into the compression groove 52, and the locking rod 54 passes through a plurality of locking cavities 53. A wedge rod 55 is inserted into the compression groove 52, and a locking spring 56 is sleeved on the wedge rod 55. The flat end of the wedge rod 55 and one end of the locking spring 56 are both in contact with the locking rod 54. A baffle 57 is provided on the end of the locking spring 56 away from the locking rod 54, and the baffle 57 is sleeved on the wedge rod 55.

[0055] The outer diameter of the wedge rod 55 is smaller than the inner diameter of the locking cavity 53 , and the outer diameters of the locking spring 56 and the baffle 57 are equal to the inner diameter of the locking cavity 53 .

[0056] After the fastening screw 51 penetrates the wall, the staff hammers the locking rod 54 into the tightening groove 52 in the fastening screw 51. When the flat end of the wedge rod 55 contacts the end of the locking rod 54, the tip of the wedge rod 55 can gradually extend to the outside of the fastening screw 51, thereby increasing the connection strength between the fastening screw 51 and the wall.

[0057] Furthermore, a rotating cylinder 18 is fixedly installed at both ends of the bottom of the main frame beam 1, and a rotating frame 19 is rotatably installed on one side surface of the wall mounting plate 4. A return spring 20 is arranged in the rotating cylinder 18, and one end of the return spring 20 is fixedly connected to the rotating frame 19, and the other end of the return spring 20 is fixedly connected to one end of the rotating frame 19.

[0058] The rotating cylinder 18 cooperates with the rotating frame 19 to achieve a hinged effect. At the same time, the return spring 20 can play a reverse reset role when the rotating cylinder 18 and the rotating frame 19 rotate, which can achieve a shock-absorbing effect to a certain extent.

[0059] Furthermore, wedge-shaped teeth 163 are fixedly installed on the upper and lower surfaces of the movable connecting plate 161 at equal intervals, and latch teeth 164 are fixedly installed symmetrically and at equal intervals inside the shock-absorbing frame 162. The wedge-shaped teeth 163 and the latch teeth 164 are engaged with each other, and the side wall of the movable connecting plate 161 is inlaid with an infrared transmitting end 165, and the side wall of the shock-absorbing frame is provided with an infrared receiving end 166. A shock-absorbing member 16 is provided between the lower part of the main frame beam 1, and the shock-absorbing member 16 consists of a movable connecting plate 161 and a shock-absorbing frame 162. The movable connecting plate 161 is inserted at both ends of the shock-absorbing frame 162, and one end of the movable connecting plate 161 is hinged to the support beam 2. An alarm 17 is symmetrically provided on the shock-absorbing frame 162.

[0060] It should be noted that the movable connecting plate 161 is movably connected to the main frame beam 1. When installing the shock absorber 16, it is necessary to first connect the movable connecting plate 161 to the support beam 2, and then insert one end of the movable connecting plate 161 into the shock absorber frame 162. At this time, the staff will insert another movable connecting plate 161 into the other end of the shock absorber frame 162. It should be noted that the teeth on the movable connecting plate 161 are made of metal elastic material, such as alloy spring steel, which can facilitate the insertion of the movable connecting plate 161 into the shock absorber frame 162. At the same time, since the movable connecting plate 161 is provided with an infrared transmitting end 165, and the shock absorbing frame 162 is provided with an infrared receiving end 166, and the shock absorbing frame 162 is provided with a battery (not shown in the figure) for powering the alarm 17, when an earthquake occurs and causes the movable connecting plate 161 and the shock absorbing frame 162 to slide relative to each other to a certain position, the infrared transmitting end 165 receives a signal from the infrared receiving end 166, and sends a signal to the alarm 17 through the infrared receiving end 166. At this time, the alarm 17 sends an alarm message.

[0061] Working principle: The staff fixes the main frame beam 1 with the reinforcement angle steel 10, and then inserts the positioning block 12 on the support beam 2 into the positioning groove 11 in the main frame beam 1, and then quickly installs the support beam 2 by inserting the bolts 3. The installation of the reinforcement rib 14 is to insert the reinforcement rib 14 into the plug-in hole of the support beam 2, and then the reinforcement rib 14 needs to insert the block 153 on the positioning plate 151 into the slot inside the reinforcement rib 14. At the same time, the positioning screw 152 can be used to fix the positioning plate 151 and the reinforcement rib 14.

[0062] After the device is assembled, the staff will insert the fastening screw 51 into the wall. At this time, the staff will hammer the locking rod 54 into the tightening groove 52 in the fastening screw 51. When the flat end of the wedge rod 55 contacts the end of the locking rod 54, the tip of the wedge rod 55 can gradually extend to the outside of the fastening screw 51, thereby increasing the connection strength between the fastening screw 51 and the wall. The shock-absorbing rubber pad 13 provided can reduce the vibration amplitude of the main frame beam during an earthquake.

[0063] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
