Description

Technical Field

[0001] The invention belongs to the technical field of building earthquake resistance, and in particular relates to a slide rail type earthquake resistance structure. Background Art

[0002] In the construction industry, rooftops in scenarios such as wooden pitched roofs, large metal-roofed venues, and traditional building reinforcements have traditionally been constructed and connected using rigid structures. This rigid connection method can ensure the stability and integrity of the building structure under normal circumstances, meeting the basic requirements of building use.

[0003] However, when an earthquake occurs or strong winds hit, rigid structures expose many serious problems. The propagation of seismic waves will cause complex dynamic responses in the building structure. Due to the lack of effective buffering and deformation capabilities, stress concentration is very likely to occur at the rigid connection nodes. When the stress exceeds the bearing limit of the material, the node will break and be damaged. This damage will not only cause local failure of the roof structure, but may also trigger a chain reaction, seriously threatening the stability of the entire building structure, and even causing serious consequences such as building collapse. What is even more difficult is that post-earthquake repair work faces huge challenges. After the rigid structure nodes are damaged, the damaged parts often need to be demolished and rebuilt on a large scale, which not only requires a lot of manpower, material resources and time, but also has the disadvantage of high repair costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a slide rail type earthquake-resistant structure for existing devices to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a slide rail type seismic resistant structure, comprising a slide platform, wherein a rafter is slidably connected to the slide platform, and when the rafter is arranged on the slide platform in an inclined manner, the lower side of the inclined surface serves as the outer side of the structure, and the inner side of the rafter is fixedly connected to a connecting rack, the upper side of the connecting rack is meshed with a fourth gear, the oblique upper side of the fourth gear is meshed with a third gear, the oblique upper side of the third gear is meshed with a second gear, the oblique upper side of the second gear is meshed with a first gear, and the inner side of the first gear is meshed with a transmission rack;

[0006] The slide is located on the inner side of the transmission rack and is fixedly installed with a fixed support block. The fixed support block is L-shaped, and a movable support block is slidably provided on the L-shaped stepped surface of the fixed support block. The movable support block is also an L-shaped structure, and the fixed support block and the movable support block are slidably matched through corresponding L-shaped stepped surfaces. A number of connecting springs are provided between the relative stepped surfaces of the fixed support block and the movable support block. The outer side of the movable support block is fixedly connected to the inner side of the transmission rack, and a purlin is installed above the movable support block, and the top of the purlin is in contact with the rafter.

[0007] The present invention further describes that a fixed beam is provided below the slide, the slide is fixedly mounted on the fixed beam, and a plurality of fixed connection blocks are embedded and installed between the slide and the fixed beam.

[0008] The present invention further describes that a shock-absorbing slide is provided on the slide platform, and a slide stop is fixedly provided on the slide platform on the outside of the shock-absorbing slide. A first slider is provided under the rafter, and the cross-section of the first slider is a square with double-sided flanges, and the first slider is adapted to the shock-absorbing slide, that is, the rafter is driven to slide in the shock-absorbing slide by the first slider, thereby realizing the sliding of the rafter relative to the slide platform.

[0009] The present invention further describes that a sliding track is provided on the fixed support block, and a second slider is fixedly provided on the movable support block. The cross-section of the second slider is T-shaped, and the second slider is adapted to the sliding track, that is, the movable support block is driven to slide in the sliding track by the second slider, thereby realizing the sliding of the movable support block relative to the fixed support block.

[0010] The present invention further describes that a first central axis is passed through the center of the first gear, a second central axis is passed through the center of the second gear, a third central axis is passed through the center of the third gear, and a fourth central axis is passed through the center of the fourth gear.

[0011] The present invention further describes that two fixed plates are fixedly provided on the slide, and the two fixed plates are respectively located on both sides of the connecting rack in a mirror-image distribution, and the two groups of terminals of the first center axis, the second center axis, the third center axis and the fourth center axis are respectively fixed on the two fixed plates.

[0012] The present invention further describes that buffer damping is fixedly installed at both ends of the shock-absorbing slideway.

[0013] The present invention further describes a seismic resistance method for a slide-rail seismic resistance structure. When an earthquake or strong wind occurs, the fixed beam, the slide platform, and the rafters are subjected to vibration or other forces. The rafters slide within the shock-absorbing slideway via the first slider, causing the rafters to slide relative to the slide platform, thereby converting the external impact force into linear displacement motion, effectively avoiding rigid collision, achieving flexible vibration absorption and energy dispersion, and effectively avoiding stress concentration and node fracture problems of traditional rigid connection structures.

[0014] At the same time, the connecting rack moves synchronously with the sliding displacement of the rafter and engages to drive the fourth gear to rotate. The rotational motion of the fourth gear is transmitted through the transmission system composed of the third gear, the second gear and the first gear.

[0015] Specifically, when the connecting rack moves inward, it drives the rafter to displace its inclined surface inward, driving the fourth gear to rotate counterclockwise, the third gear to rotate clockwise, the second gear to rotate counterclockwise, and the first gear to rotate clockwise, thereby engaging and driving the transmission rack to move downward, forming a coordinated displacement compensation mechanism to cooperate with the inward tilting movement of the rafter. When the connecting rack moves outward, the rotation direction of each gear is reversed accordingly to ensure that the purlin always maintains dynamic and stable support for the rafter. At the same time, the connecting spring plays a dual role of longitudinal vibration buffering and structural support through elastic deformation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) By providing a sliding platform, rafter sliding cooperation and buffer damping, when an earthquake or strong wind occurs, the rafters can slide on the sliding platform, converting the external impact force into linear displacement motion, effectively avoiding rigid collision, achieving flexible vibration absorption and energy dispersion, avoiding the stress concentration and node fracture problems of traditional rigid connection structures, improving the earthquake and wind resistance of the building roof structure, and ensuring the stability of the overall building structure;

[0018] (2) By providing a buffer structure consisting of a connecting rack, multiple gears, a transmission rack, a fixed support block, a movable support block and a connecting spring, when the transmission rack moves under the action of an external force, the movable support block and the fixed support block slide relative to each other through the transmission between a series of gears and gears, and between gears and racks, and the connecting spring deforms, which plays a role in buffering and absorbing energy, reducing the damage to the overall structure caused by sudden external force impact. At the same time, the purlin dynamically supports the rafters as the movable support block moves, ensuring the stability and position accuracy of the rafters, and further enhancing the stability and reliability of the structure.

DETAILED DESCRIPTION

[0027] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0028] The embodiment of the present invention provides a slide rail type earthquake resistant structure, such as Figure 1 、 Figure 2 and Figure 5 As shown, the sliding rail type seismic resistant structure includes a slide 1, and a rafter 2 is slidably connected to the slide 1. When the rafter 2 is arranged obliquely on the slide 1, the lower side of the inclined surface is used as the outer side of the structure. The inner side of the rafter 2 is fixedly connected to a connecting rack 21, and the upper part of the connecting rack 21 is meshed with a fourth gear 8, and the oblique upper part of the fourth gear 8 is meshed with a third gear 71, and the oblique upper part of the third gear 71 is meshed with a second gear 7, and the oblique upper part of the second gear 7 is meshed with a first gear 6, and the inner side of the first gear 6 is meshed with a transmission rack 5.

[0029] When the rafter 2 slides on the slide 1, the connecting rack 21 moves with the rafter 2. While the connecting rack 21 moves, it drives the third gear 71, the second gear 7, the first gear 6 and the transmission rack 5 to engage and transmit, thereby realizing the up and down movement of the transmission rack 5.

[0030] like Figure 2 and Figure 5As shown, a fixed support block 3 is fixedly installed on the slide 1 on the inner side of the transmission rack 5. The fixed support block 3 is L-shaped, and a movable support block 31 is slidably provided on the L-shaped stepped surface of the fixed support block 3. The movable support block 31 is also L-shaped, and the fixed support block 3 and the movable support block 31 are slidably matched through corresponding L-shaped stepped surfaces. A plurality of connecting springs 32 are provided between the opposite stepped surfaces of the fixed support block 3 and the movable support block 31. The outer side of the movable support block 31 is fixedly connected to the inner side of the transmission rack 5. A purlin 4 is installed above the movable support block 31, and the top of the purlin 4 is in contact with the rafter 2.

[0031] When the transmission rack 5 is moved by an external force, the movable support block 31, fixedly connected to the transmission rack 5, moves with it. During this movement, the movable support block 31 slides relative to the fixed support block 3, causing the connecting spring 32 to deform, buffering and absorbing energy, thereby reducing damage to the overall structure caused by sudden external force. The purlin 4 moves with the movement of the movable support block 31, while supporting the rafters 2, ensuring their stability and positional accuracy.

[0032] In certain preferred embodiments, Figure 1 As shown, a fixed beam 10 is provided below the slide 1, and the slide 1 is fixedly mounted on the fixed beam 10. A number of fixed connection blocks 13 are embedded and installed between the slide 1 and the fixed beam 10. The fixed beam 10 serves as the basic supporting structure, bearing the weight of the slide 1 and the equipment carried thereon. The fixed connection blocks 13 serve to strengthen the connection, increasing the strength and stability of the connection between the slide 1 and the fixed beam 10.

[0033] In certain preferred embodiments, Figure 1 and Figure 3 As shown, the slide 1 is provided with a shock-absorbing slide 11. A slide block 12 is fixedly mounted on the slide 1 outside the shock-absorbing slide 11. A first slider 22 is provided below the rafter 2. The first slider 22 has a square cross-section with double-sided flanges and is compatible with the shock-absorbing slide 11. The first slider 22 drives the rafter 2 to slide within the shock-absorbing slide 11, thereby enabling the rafter 2 to slide relative to the slide 1. Through the sliding cooperation between the first slider 22 and the shock-absorbing slide 11, the vibration energy generated by the rafter 2 under external impacts such as earthquakes or strong winds can be effectively guided and converted into sliding relative to the slide 1. At the same time, the slide block 12 provides the necessary boundary constraints for the first slider 22, preventing it from accidentally falling out, improving the movement stability of the rafter 2, and thus enhancing the earthquake and wind resistance of the entire structure.

[0034] In certain preferred embodiments, Figures 4 to 6 As shown, a sliding track 301 is provided on the fixed support block 3, and a second slider 311 is fixedly provided on the movable support block 31. The cross-section of the second slider 311 is T-shaped, and the second slider 311 is adapted to the sliding track 301, that is, the movable support block 31 is driven to slide in the sliding track 301 by the second slider 311, thereby realizing the sliding of the movable support block 31 relative to the fixed support block 3.

[0035] In certain preferred embodiments, Figure 5 As shown, a first central axis 61 is passed through the center of the first gear 6 , a second central axis 72 is passed through the center of the second gear 7 , a third central axis 73 is passed through the center of the third gear 71 , and a fourth central axis 81 is passed through the center of the fourth gear 8 .

[0036] In certain preferred embodiments, Figure 1 As shown, two fixed plates 9 are fixedly provided on the slide 1, and the two fixed plates 9 are respectively located on both sides of the connecting rack 21 in a mirror-image distribution, and the two groups of terminals of the first center axis 61, the second center axis 72, the third center axis 73 and the fourth center axis 81 are respectively fixed on the two fixed plates 9.

[0037] In certain preferred embodiments, Figure 2 As shown, buffer dampers 111 are fixedly installed at both ends of the shock-absorbing slideway 11, and the buffer dampers 111 are used to further absorb vibration energy.

[0038] In the above embodiment, when an earthquake or strong wind occurs, the fixed beam 10, the slide 1 and the rafter 2 are subjected to vibration or other forces, and the rafter 2 slides in the shock-absorbing slide 11 through the first slider 22, causing the rafter 2 to produce a sliding displacement relative to the slide 1, converting the external impact force into a linear displacement motion, effectively avoiding rigid collision, achieving flexible vibration absorption and energy dispersion, and effectively avoiding the stress concentration and node fracture problems of traditional rigid connection structures.

[0039] At the same time, the connecting rack 21 moves synchronously with the sliding displacement of the rafter 2, and engages to drive the fourth gear 8 to rotate. The rotational motion of the fourth gear 8 is transmitted through the transmission system composed of the third gear 71, the second gear 7 and the first gear 6.

[0040] Specifically, when the connecting rack 21 moves inward, it drives the rafter 2 to displace its inclined surface inward, drives the fourth gear 8 to rotate counterclockwise, the third gear 71 to rotate clockwise, the second gear 7 to rotate counterclockwise, and the first gear 6 to rotate clockwise, thereby engaging and driving the transmission rack 5 to move downward, forming a coordinated displacement compensation mechanism to cooperate with the inward tilting movement of the rafter 2. When the connecting rack 21 moves outward, the rotation direction of each gear is reversed accordingly to ensure that the purlin 4 always maintains dynamic and stable support for the rafter 2. At the same time, the connecting spring 32 plays the dual role of longitudinal vibration buffering and structural support through elastic deformation.
