Description

Technical Field

[0001] The present invention relates to the technical field of building earthquake resistance, and in particular to an earthquake resistance method for steel structures used in assembled buildings. Background Art

[0002] Earthquake resistance of building steel structures refers to the ability of buildings to remain stable and safe during earthquakes through design and construction technology.

[0003] The mechanical and electrical engineering facilities such as water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, and communications of buildings reinforced with earthquake-resistant supports can reduce earthquake damage, reduce and prevent the occurrence of secondary disasters as much as possible when an earthquake with the seismic fortification intensity of the region occurs, thereby achieving the goal of reducing casualties and property losses.

[0004] For example, a Chinese patent with publication number CN112267578B discloses an anti-seismic device for steel structures used in prefabricated buildings, which relates to the field of anti-seismic technology for steel structures. It includes a first fixing mechanism, one end of which is welded to a second fixing mechanism. Through the coordination of various accessories, the changes in the internal stress of the steel structure can be monitored while reinforcing the steel structure nodes. When the internal stress of the steel structure nodes changes greatly due to fracture, the device will transmit a warning signal to the inside of the corresponding monitoring room on the ground, alarm the monitoring personnel, improve the safety performance of the device, and emit warning light and warning sound at the same time to warn the maintenance personnel, so as to facilitate the maintenance personnel to carry out maintenance, improve the maintenance efficiency, and reduce the maintenance work intensity. By setting the first fixing mechanism and the second fixing mechanism, the device can be relatively simple to apply to steel structures of different sizes, thereby greatly improving the scope of application of the device.

[0005] However, the above-mentioned seismic resistant device for steel structure of prefabricated building still has some shortcomings in actual use: 1. In the above-mentioned prior art, the screws connect the positioning ring and the steel structure, and the positioning ring can move. Therefore, after the positioning ring moves, it is necessary to punch holes in the steel structure so that the screws can be inserted and installed between the positioning ring and the steel structure. Therefore, punching holes in the steel structure body will reduce the strength of the entire steel structure and affect the quality of the steel structure itself.

[0006] 2. Secondly, in the prior art, the first fixing mechanism is a direct structure, which cannot be adjusted in angle. Therefore, it has a certain degree of uniformity for different prefabricated building steel structures, resulting in poor applicability.

[0007] 3. Then, in the prior art, the alarm in the prior art mainly senses stress through a pressure sensor, so the pressure sensor needs to work and needs to be powered by an external power source at all times, thereby consuming a large amount of electricity.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing seismic-resistant devices for steel structures used in prefabricated buildings. Summary of the invention

[0019] Preferably, upper and lower ends of the two anti-seismic alarms on the two reinforcement members are both hingedly mounted with support frames, and the support frames on the two anti-seismic alarms are staggered and cross-distributed.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-Figure 8 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0036] The embodiment of the present application discloses a method for seismic resistance of steel structures for prefabricated buildings; the method is mainly used to solve the problem in the prior art that, when the prior art is connected to the building steel structure 1, holes need to be punched in the main body of the building steel structure 1, which will cause the strength of the entire building steel structure 1 to be reduced and affect the quality of the building steel structure 1 itself; secondly, the prior art cannot adjust the angle, so it has a certain degree of uniformity for different building steel structures 1, resulting in poor applicability.

[0037] Then, in the prior art, the alarm is mainly performed by sensing stress through a pressure sensor, sensing the change of pressure difference to realize the alarm. Therefore, the pressure sensor needs to work in real time and needs to be powered by an external power supply at all times, thereby consuming a large amount of electricity. The trigger component 4 in the present invention can ensure that the power supply 46 in the earthquake alarm 3 is in a standby state for a long time to avoid power consumption. When the trigger component 4 senses that the building steel structure 1 is deformed or the device in the present invention is loose, the trigger component 4 can be triggered. At this time, the power supply 46 energizes the alarm indicator light 47 to start the alarm. Example

[0038] See also Figure 1 and Figure 2As shown, an anti-seismic device for a prefabricated steel structure for a building includes a building steel structure 1, which is arranged on the ground. The building steel structure 1 is mainly in a frame shape, and reinforcing ribs of different shapes are arranged on the frame shape.

[0039] The seismic reinforcement component 2 is installed at the node of the building steel structure 1 and is used to reinforce the seismic effect of the building steel structure 1. The seismic reinforcement component 2 includes two symmetrically distributed and mutually hinged reinforcement members 20 and a fixed bracket 21 for fixing the reinforcement member 20 to the building steel structure 1. The fixed bracket 21 is slidably arranged on the reinforcement member 20.

[0040] The earthquake-resistant reinforcement component 2 is mainly installed on the surface of the building steel structure 1. In the present invention, there are two reinforcement members 20, and one end of the two reinforcement members 20 is hinged to each other, so that the angle between the two reinforcement members 20 can be adjusted, further improving the applicability of the present invention.

[0041] The fixing base 21 is mainly used for connecting the present invention with the building steel structure 1, and the fixing base 21 can quickly clamp and fix the building steel structures 1 of different thicknesses without drilling holes in the body of the building steel structure 1, thereby greatly ensuring the stability of the building steel structure 1 itself.

[0042] The opposite sides of the two reinforcement members 20 are fixedly connected with the earthquake-resistant alarm device 3 , and the inner side of the earthquake-resistant alarm device 3 is provided with a detection lead pendant 30 for detecting whether the steel structure is deformed and vibrated.

[0043] The earthquake-resistant alarm 3 is arranged on the reinforcement 20. When looseness occurs between the reinforcement 20 and the building steel structure 1, it will cause an alarm to alert the maintenance personnel to perform maintenance; when the building steel structure 1 is deformed, it will also cause an alarm to alert the maintenance personnel to perform maintenance.

[0044] See also Figure 2 and Figure 3 As shown, it is a schematic diagram of the structure of the hinge between the two reinforcement members 20 in this embodiment; the two reinforcement members 20 are hinged to each other at one end away from the seismic alarm 3, and a reinforcement plate clamp 200 is provided at one end of the reinforcement member 20 on one side, and a hinge hole 201 is opened on the reinforcement plate clamp 200, and a hinge hole 201 is also opened on the reinforcement member 20 on the other side. The hinge hole 201 on the reinforcement member 20 coincides with the hinge hole 201 on the reinforcement plate clamp 200 and a reinforcement shaft 202 is passed through them together, and reinforcement nuts 203 are installed on both sides of the reinforcement shaft 202 by threaded connection.

[0045] The two reinforcement members 20 are connected by a reinforcement shaft 202 and a reinforcement nut 203. If the reinforcement member 20 on one side is damaged or deformed, it can be removed for replacement and maintenance by cooperating with the reinforcement shaft 202 and the reinforcement nut 203.

[0046] See also Figure 2 and Figure 4 As shown, it is a structural schematic diagram of the connection between the building steel structure 1 and the reinforcement 20; the fixed base 21 includes a cross block 210, an extension plate 211, a locking connection shaft 212 and a locking nut 213, the cross block 210 is symmetrically slidably arranged on the reinforcement 20, the extension plate 211 is installed on both sides of the height direction of the cross block 210, the locking connection shaft 212 slides through the two extension plates 211 on the cross block 210, and the locking nuts 213 are arranged on both sides of the length direction of the locking connection shaft 212 by threaded connection.

[0047] It should be noted that a cross-shaped groove for the cross-shaped block 210 to slide is provided on the reinforcement 20, so that two symmetrical cross-shaped blocks 210 can slide relative to each other, and the positions of the two cross-shaped blocks 210 can be adjusted to ensure the tightness of the fixation between the reinforcement 20 and the building steel structure 1.

[0048] In the initial state, the locking connecting shaft 212 on the extension plate 211 is not inserted into the bar slide groove 214 on the extension plate 211. After the two reinforcements 20 are pressed against the building steel structure 1, the locking connecting shaft 212 is inserted into the bar slide groove 214 on the extension plate 211, and then the two locking nuts 213 are rotated so that the two locking nuts 213 are pressed against the outer wall of the extension plate 211. At this time, the extension plate 211, the locking connecting shaft 212 and the locking nuts 213 realize the fixation between the reinforcement 20 and the building steel structure 1.

[0049] See also Figure 4 and Figure 5 As shown, it is a schematic diagram of the structure of adjusting the cross block 210 in the reinforcement 20 in this embodiment; an adjusting threaded rod 216 for adjusting the position of the cross block 210 is also provided between the reinforcement 20 and the cross block 210, and the adjusting threaded rod 216 is rotatably provided on the reinforcement 20 through a bearing, and the adjusting threaded rod 216 is distributed in parallel along the length direction of the reinforcement 20, and the cross block 210 is threadedly connected to the adjusting threaded rod 216, and the adjusting threaded rod 216 is a bidirectional thread structure.

[0050] During the specific implementation process, the threaded rod 216 is rotated to adjust the two symmetrically distributed cross blocks 210 on the threaded rod 216 to move relative to each other, thereby ensuring that the cross block 210 and the extension plate 211 on the cross block 210 can be adjusted in position. Because the surface of the building steel structure 1 is not entirely smooth, and there will be protrusions in some places, the threaded rod 216 can be adjusted to ensure that the cross block 210 and the extension plate 211 are adjusted to a smooth and protrusion-free position on the building steel structure 1, thereby ensuring the connection stability between the reinforcement 20 and the building steel structure 1.

[0051] See also Figure 6 and Figure 7 4 is a schematic diagram of the structure used to trigger the alarm indicator light 47 in the present invention; the anti-seismic alarm 3 is also provided with a trigger component 4 to avoid excessive power consumption caused by long-term detection of the alarm device, and the trigger component 4 includes a No. 1 rope 40, a fixed ball 41, a No. 2 rope 42, a No. 3 rope 43, a metal sensor sheet 44, a sensor metal strip 45 and a power supply 46; the fixed ball 41 is connected to the inner wall of the anti-seismic alarm 3 through the No. 1 rope 40, and is vertically distributed downward, and the bottom of the fixed ball 41 is connected to the No. 2 rope 42, and the bottom of the fixed ball 41 is connected to the No. 1 rope 40. The No. 1 rope 42 is connected to the detection plumb bob 30, one end of the No. 3 rope 43 is connected to the fixed ball 41, and the other end is equipped with a metal sensor sheet 44, and the end of the metal sensor sheet 44 away from the No. 3 rope 43 is equipped with a reset insulating spring 48, and the reset insulating spring 48 is installed on the inner wall of the anti-seismic alarm 3, and the sensing metal strips 45 are symmetrically arranged on the periphery of the metal sensor sheet 44, and an alarm indicator light 47 is connected to the sensing metal strip 45 on one side, and the other end of the sensing metal strip 45 is connected to a power supply 46.

[0052] In the prior art, for the earthquake-resistant device of the building steel structure 1, the device generally used for sensing vibration and earthquake resistance needs to be powered on for a long time. For example, the existing pressure sensor needs to sense the state of the building steel structure 1 in real time. Therefore, long-term power supply consumes a lot of electricity. If a battery is used for power supply, the battery needs to be replaced regularly in a short period of time, so the operation is complicated.

[0053] The present invention can save power for power supply devices such as batteries under normal conditions. When the trigger component 4 is triggered, power supply devices such as batteries start to supply power, so that the alarm indicator light 47 lights up, and an alarm sound is sounded at the same time, reminding maintenance personnel to check and maintain in time.

[0054] During the specific implementation process, when a node of the building steel structure 1 breaks and causes the building steel structure 1 to deform, the detection plumb bob 30 in the seismic alarm 3 will be in a tilted state. At this time, the detection plumb bob 30 will pull the metal sensing sheet 44 to one side through the fixed ball 41. At this time, the metal sensing sheet 44 will contact the surrounding sensing metal strip 45 after the displacement. At this time, the sensing metal strip 45, the metal sensing sheet 44 and the alarm indicator light 47 will change from a disconnected state to a connected state. At this time, the electricity in the power supply 46 will pass through the metal sensing sheet 44 and the sensing metal strip 45 and finally act on the alarm indicator light 47, causing the alarm indicator light 47 to light up, and an alarm sound will sound to remind the maintenance personnel.

[0055] See also Figure 5 As shown, the upper and lower ends of the two anti-seismic alarms 3 on the two reinforcement members 20 are both hingedly mounted with support frames 60 , and the support frames 60 on the two anti-seismic alarms 3 are staggered and cross-distributed.

[0056] After the two reinforcements 20 are installed on the building steel structure 1, since the two reinforcements 20 are hinged structures, they cannot play a supporting and reinforcing role. At this time, a support frame 60 is needed to support the two reinforcements 20. By forming a diamond structure between the support frame 60 and the reinforcements 20, the building steel structure 1 is supported and reinforced to prevent the entire building steel structure 1 from breaking.

[0057] Look again Figure 6 and Figure 7 As shown, a plurality of holes 61 are provided at equal intervals on the support frame 60 , and a support threaded rod 62 is inserted and installed in the overlapping holes 61 of the support frames 60 on the two anti-seismic alarms 3 , and a plurality of support nuts 63 are provided on the support threaded rod 62 .

[0058] It should be noted that the support frames 60 are symmetrically arranged on the two reinforcement members 20 , and the main purpose is to ensure the support stability of the reinforcement members 20 after the support frames 60 cross.

[0059] After the reinforcement 20 is fixed on the building steel structure 1, the support frames 60 on the two reinforcements 20 are crossed with each other. At this time, the clamping holes 61 on the crossed support frames 60 are ensured to overlap with each other. At this time, the support threaded rod 62 is inserted and installed into the overlapping clamping holes 61 on the two support frames 60, and the support nut 63 is installed on the support threaded rod 62; at this time, a quadrilateral structure is formed between the support frame 60 and the reinforcement 20.

[0060] Embodiment 2: On the basis of Embodiment 1, in order to further improve the adaptability of the present invention, the present invention further proposes to adjust the position of the locking connecting shaft 212 on the extension plate 211, and adjust the position of the cross block 210. By adjusting the position of the cross block 210, it is ensured that the two ends of the reinforcement 20 and the middle body can fit on the surface of the building steel structure 1. The locking connecting shaft 212 is adjusted in position to ensure clamping and reinforcement of building steel structures 1 of different thicknesses.

[0061] Replay Figure 4 and Figure 5 As shown, in order to further ensure that two strip-shaped slide grooves 214 for adjusting the position of the locking connection shaft 212 are provided on the extension plate 211, a resisting threaded rod 215 is installed on the side wall of the extension plate 211 by means of a threaded connection, and the resisting threaded rod 215 can movably rest against the locking connection shaft 212.

[0062] It should be noted that when the reinforcement 20 is against the surface of the building steel structure 1, the extension plate 211 on the reinforcement 20 is inserted into the two ends of the building steel structure 1. At this time, the locking connection shaft 212 is installed in the bar slide groove 214 on the extension plate 211, and then the interference threaded rod 215 is rotated. It can ensure that the interference threaded rod 215 always contacts the locking connection shaft 212 with the surface of the building steel structure 1, avoiding shaking between the building steel structure 1 and the extension plate 211, which affects the reinforcement effect of the entire reinforcement 20.

[0063] Therefore, the connection between the reinforcement member 20 and the extension plate 211 is mainly achieved by squeezing the extension plate 211 through the locking connecting shaft 212 and the locking nut 213 , so that the building steel structure 1 is clamped by the extension plate 211 .

[0064] See also Figure 8 As shown, in addition, the present invention also provides a method for seismic resistance of a steel structure for an assembled building, and a method for seismic resistance of a building steel structure 1, as shown below: S1. Product adjustment: first, place the two reinforcements 20 against the nodes of the building steel structure 1, then rotate the adjusting threaded rod, and the adjusting threaded rod 216 drives the two cross-shaped blocks 210 at its upper end to move relative to each other, so as to adjust the position of the extension plate 211 connected to the cross-shaped block 210, ensure that the extension plate 211 can be located in a smooth and flat place of the building steel structure 1, and finally ensure that the two fixed brackets 21 are evenly distributed on the building steel structure 1.

[0065] S2. Reinforced connection: Then, the building steel structure 1 is clamped and fixed by the locking connection shaft 212 and the extension plate 211, and at the same time, the locking connection shaft 212 is limited and squeezed by the contact threaded rod 215 to prevent the reinforcement 20 from falling off or shaking, so that it is connected to the building steel structure 1, and ensure that the two fixed sockets 21 make the reinforcement 20 completely fit the surface of the building steel structure 1.

[0066] S3. Alarm activation: The earthquake-resistant alarm device 3 is arranged on the reinforcement member 20. When the reinforcement member 20 is connected to the building steel structure 1, the detection lead pendant 30 will droop naturally. When the node of the building steel structure 1 breaks and causes the building steel structure 1 to deform, the detection lead pendant 30 in the earthquake-resistant alarm device 3 will be in a tilted state. At this time, the detection lead pendant 30 will pull the metal sensing sheet 44 to move to one side through the fixed ball 41. At this time, the metal sensing sheet 44 will contact the surrounding sensing metal strip 45 after the displacement. At this time, the sensing metal strip 45, the metal sensing sheet 44 and the alarm indicator light 47 change from a disconnected state to a connected state. At this time, the electricity in the power supply 46 will finally act on the alarm indicator light 47 through the metal sensing sheet 44 and the sensing metal strip 45, so that the alarm indicator light 47 lights up, and an alarm sound will sound to remind the maintenance personnel.

[0067] S4, reinforcement treatment: when the earthquake warning device 3 sounds an alarm, check it, solve the problems in time, and cancel the alarm.

[0068] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
