Description

Technical Field

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

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion; generally, steel structures require rust removal, galvanizing, or painting, and regular maintenance.

[0003] Existing steel structures typically use welding or direct threaded connection between beams and steel columns, resulting in a relatively simple structure. However, during an earthquake, the connection points are prone to bending or breaking, leading to weak earthquake resistance. Utility Model Content

[0004] The purpose of this utility model is to provide an earthquake-resistant steel structure for buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seismic-resistant steel structure, comprising steel columns, beams, connecting components, and reinforcing bridges. Connecting components are provided on the outer side of the steel columns. The beams are vertically connected to the outer side of the steel columns via the connecting components. One end of the reinforcing bridge is connected to the steel column, and the other end is connected to the beam. The connecting components include a column sleeve, a beam sleeve, a positioning screw, a threaded seat, and a reinforcing ring. The column sleeve is connected to the outer side of the steel column. The beam sleeve is vertically connected to the middle of the outer side of the column sleeve, and the beam is connected to the inside of the beam sleeve. The outer end of the positioning screw is inserted through the side of the beam sleeve. The threaded seat is located inside the beam sleeve, and the inner end of the positioning screw is threadedly connected to the threaded seat. The reinforcing ring is located at the junction of the beam sleeve and the column sleeve.

[0006] Preferably, the reinforced bridge includes a connecting plate, a bridge frame, and a connecting piece, with the bridge frame and the connecting piece connected to the steel column and the crossbeam at both ends respectively via a connecting plate.

[0007] Preferably, the connecting piece is vertically fixed to the bottom end of the cable tray.

[0008] Preferably, the inner end of the positioning screw is provided with a fixing plate, and the fixing plate is in contact with the web of the crossbeam.

[0009] Preferably, the reinforcing ring is a triangular structure with an arc-shaped bevel.

[0010] Preferably, the positioning screw and the center of the web of the crossbeam are located on the same horizontal line.

[0011] Preferably, the intersection angle between the reinforced bridge and the column sleeve and beam sleeve forms a triangular structure.

[0012] Preferably, two sets of positioning screws and threaded seats are provided, and they are arranged symmetrically in the middle of the beam sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are: A connecting assembly is installed. The crossbeam is made of H-shaped steel, and two sets of positioning bolts are installed inside the beam sleeve. The crossbeam is inserted into the beam sleeve, and its top and bottom flanges are fixed to the beam sleeve with bolts. The positioning bolts are then used to fix it at the front and back. This double fixation makes the crossbeam connection more stable. A curved reinforcing ring is installed at the junction of the beam sleeve and the column sleeve. The curved reinforcing ring can disperse stress and prevent stress generated during an earthquake from concentrating at the junction of the beam sleeve and the column sleeve, which could lead to bending or tearing of the joint. A reinforcing bridge is also installed. The two ends of the reinforcing bridge are connected to the steel column and the crossbeam respectively, and the angle between the reinforcing bridge and the junction of the column sleeve and the beam sleeve forms a triangular structure, which makes the connection between the steel column and the crossbeam more stable, stronger, reduces the possibility of breakage, and provides better earthquake resistance.

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figures 1-2 This utility model provides an earthquake-resistant steel structure for buildings, including a steel column 1, a crossbeam 2, a connecting component 3, and a reinforcing bridge 4. The connecting component 3 is provided on the outside of the steel column 1, and the crossbeam 2 is vertically connected to the outside of the steel column 1 through the connecting component 3. One end of the reinforcing bridge 4 is connected to the steel column 1, and the other end is connected to the crossbeam 2.

[0020] Please see Figures 2-3This utility model provides an earthquake-resistant steel structure for buildings. The connecting component 3 includes a column sleeve 31, a beam sleeve 32, a positioning screw 33, a threaded seat 34, and a reinforcing ring 35. The column sleeve 31 is bolted to the outside of the steel column 1. The beam sleeve 32 is integrally formed and perpendicular to the middle of the outside of the column sleeve 31. The crossbeam 2 is bolted to the inside of the beam sleeve 32 to connect the crossbeam 2 to the steel column 1. The outer end of the positioning screw 33 is inserted through the side of the beam sleeve 32, and the threaded seat 34 is welded to the inner side of the beam sleeve 32. The inner end of the positioning screw 33 is threadedly connected to the threaded seat 34. There are two sets of positioning screws 33 and threaded seats 34, which are symmetrically arranged in the middle of the beam sleeve 32. They are used to fix the crossbeam 2 laterally, making the connection between the crossbeam 2 and the beam sleeve 32 more stable. The reinforcing ring 35 is integrally formed at the junction of the beam sleeve 32 and the column sleeve 31. The reinforcing ring 35 is a triangular structure with an arc-shaped inclined surface. The arc-shaped structure can disperse stress and prevent the stress generated by the earthquake from acting on the junction of the beam sleeve 32 and the column sleeve 31, reducing the possibility of deformation or breakage at the connection between the steel column 1 and the crossbeam 2, and enhancing the seismic resistance of the steel structure.

[0021] The positioning screw 33 and the center of the web of the crossbeam 2 are located on the same horizontal line, which can make the crossbeam 2 more evenly stressed. The inner end of the positioning screw 33 is welded with a fixing plate 331, and the fixing plate 331 is in contact with the web of the crossbeam 2, which can increase the contact area between the positioning screw 33 and the crossbeam 2, making the lateral fixation more stable.

[0022] Please see Figures 2-3 This utility model provides an earthquake-resistant steel structure for buildings. The reinforced bridge 4 includes a connecting plate 41, a bridge frame 42, and a connecting piece 43. The two ends of the bridge frame 42 and the connecting piece 43 are respectively connected to the steel column 1 and the beam 2 through a connecting plate 41. The connecting piece 43 is vertically fixed to the bottom end of the bridge frame 42, making the connection between the bridge frame 42 and the connecting plate 41 more stable and preventing the middle of the bridge frame 42 from bending during an earthquake. The intersection angle of the reinforced bridge 4 with the column sleeve 31 and the beam sleeve 32 forms a triangular structure. The triangular stable structure can make the connection between the steel column 1 and the beam 2 more stable and can also enhance the strength of the steel structure, making the steel structure more earthquake-resistant as a whole.

[0023] Specifically, first, the column sleeve 31 is fixed to the outside of the steel column 1. Then, the crossbar 2 is inserted into the beam sleeve 32 so that the crossbar 2 contacts the steel column 1. Next, the top and bottom flanges of the crossbeam 2 are fixed to the inside of the beam sleeve 32 with bolts. Then, the positioning screws 33 are rotated on both sides so that the connecting piece 43 at the inner end of the positioning screw 33 is tightly attached to the web of the crossbeam to fix the front and back of the crossbeam. Then, the cable tray 42 with connecting plates 43 welded on both sides is fixed to the steel column 1 and the crossbeam respectively, so that the intersection angle of the cable tray with the beam sleeve 32 and the column sleeve 31 forms a triangular stable structure. The other end of the crossbeam 2 adopts the same connection method.
