Description

Technical Field

[0001] This application relates to the field of bridge technology, specifically to bridge suspension point structures. Background Technology

[0002] Standardization and industrialization in China's bridge construction are new trends in the bridge industry. Promoting prefabricated construction technology helps reduce pollution, conserve resources, improve labor productivity, and promote the deep integration of the construction industry with informatization and industrialization. Under the industrialized model, outdated construction methods are transformed into highly efficient prefabrication and on-site hoisting methods, achieving a fast and low-cost construction process. This reduces quality defects caused by on-site manual operations, reduces on-site labor, lowers pollution such as dust, mud, and noise, saves land, reduces investment costs, conserves manpower and resources, and improves construction progress, making project progress significantly faster and safer. Prefabricated bridges represent a new trend in bridge development; however, prefabricated structures have relatively poor seismic performance, which requires special consideration during design and construction.

[0003] Traditional bridge lifting point structures typically use simple hooks or rings to directly connect to the bridge deck. However, due to stress concentration, cracks and deformations are prone to occur at the lifting points, accelerating fatigue damage and making the lifting process unstable and less safe. This increases the risk of catastrophic accidents such as beam falls. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a bridge lifting point structure, which has the advantages of stable lifting and high safety, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a bridge suspension point structure, including a bridge body and two sets of reserved holes at both ends of the bridge body, wherein each of the reserved holes is provided with a connecting component inside;

[0006] Each of the connecting components includes a lifting rod, a lifting ring is fixedly connected to the top of each lifting rod, a steel pad is fixedly connected to the bottom of each lifting ring, two rubber pads are in contact with the upper surface of each steel pad, a fixing plate is fixedly connected to the upper surface and bottom of each pair of adjacent rubber pads, and a reset plate is fixedly connected between each pair of adjacent fixing plates.

[0007] The above-mentioned scheme, through the combination of connecting components set in the reserved holes, lifting rods, lifting rings, steel pads, and rubber pads, greatly enhances the connection stability between the upper and lower structures of the bridge. The design can effectively disperse and bear pressure during the hoisting process, reducing relative displacement caused by weak connections, thereby avoiding damage such as beam falling. The introduction of the reset plate, especially its multi-segment bent design, not only improves the reset performance of the rubber pad, but also provides additional seismic support for the bridge under extreme load conditions such as earthquakes. The rubber pad plays a good protective role for the bridge body during the hoisting process. It can absorb and disperse the impact force generated during the hoisting process, reduce direct damage to the bridge structure, and thus extend the service life of the bridge.

[0008] Furthermore, each of the aforementioned lifting rings is integrally formed with the lifting rod adjacent to it.

[0009] The above solution and design not only enhance the connection strength between the lifting ring and the lifting rod, but also simplify the manufacturing process and improve the reliability and durability of the overall structure.

[0010] Furthermore, each of the rubber pads has a connecting block fixedly connected to both sides, and each connecting block has a connecting hole on one side.

[0011] The above solution, through the connection hole and its design, facilitates the connection of two adjacent rubber pads.

[0012] Furthermore, each of the reset pieces is made of elastic steel sheet, and each of the reset pieces is made of multiple bent segments.

[0013] The above scheme and settings can improve the reset performance of the rubber pad and prevent plastic deformation caused by prolonged compression.

[0014] Furthermore, each of the rubber pads has two limiting rods fixedly connected to its bottom, and each limiting rod is inserted into the adjacent steel pad.

[0015] The above solution and settings can effectively prevent the rubber pad from rotating.

[0016] Furthermore, each of the lifting rods has a threaded top end, and each of the lifting rods has a threaded mounting nut connected to its top end.

[0017] The above solution, with its nut installation, makes it easy for users to install the lifting rod.

[0018] Furthermore, the diameter of each of the lifting rings is smaller than the diameter of the lifting rod, and the center of each of the lifting rings is on the same reference plane as the center of the lifting rod that is next to it.

[0019] The above scheme and settings facilitate the insertion of the lifting rod and lifting ring into the reserved hole.

[0020] Furthermore, the thickness of the steel pad is not less than 40mm.

[0021] The above solution ensures that the steel pad has sufficient strength and rigidity to withstand the pressure generated during hoisting.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The bridge's lifting point structure, through the combination of connecting components installed in pre-drilled holes, including lifting rods, lifting rings, steel pads, and rubber pads, greatly enhances the connection stability between the upper and lower structures of the bridge. The design effectively disperses and withstands pressure during lifting, reducing relative displacement caused by weak connections and thus preventing damage such as beam falls. The introduction of the reset plate, especially its multi-segment bent design, not only improves the reset performance of the rubber pad but also provides additional seismic support for the bridge under extreme load conditions such as earthquakes. The rubber pads provide excellent protection for the bridge structure during lifting, absorbing and dispersing the impact forces generated, reducing direct damage to the bridge structure, and thus extending the bridge's service life.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 3 and Figure 4 The bridge suspension point structure in this embodiment includes a bridge body 1 and two sets of reserved holes 101 at both ends of the bridge body 1. Each reserved hole 101 is provided with a connecting component 2 inside.

[0032] Each connecting component 2 includes a lifting rod 201, with a lifting ring 202 fixedly connected to the top of each lifting rod 201, and a steel pad 203 fixedly connected to the bottom of each lifting ring 202. The upper surface of each steel pad 203 contacts two rubber pads 204. A fixing plate 205 is fixedly connected to the upper and bottom of one end of each pair of adjacent rubber pads 204. A reset piece 206 is fixedly connected between each pair of adjacent fixing plates 205. The rubber pads 204 are designed to protect the bridge body 1 during hoisting.

[0033] Please see Figure 1 , Figure 2 and Figure 4 Each lifting ring 202 is integrally formed with its adjacent lifting rod 201. This design not only enhances the connection strength between the lifting ring 202 and the lifting rod 201, but also simplifies the manufacturing process and improves the reliability and durability of the overall structure. Each rubber pad 204 has a connecting block 3 fixedly connected to both sides. Each connecting block 3 has a connecting hole 4 on one side. The connection hole 4 facilitates the connection of two adjacent rubber pads 204.

[0034] Please see Figure 1 , Figure 3 and Figure 4 The steel pad 203 is at least 40mm thick, ensuring that it has sufficient strength and rigidity to withstand the pressure generated during hoisting. Each reset piece 206 is made of elastic steel and is multi-segmented. This design improves the reset performance of the rubber pad 204 and prevents plastic deformation caused by prolonged compression. Two limiting rods 5 are fixedly connected to the bottom of each rubber pad 204, and each limiting rod 5 is inserted into the adjacent steel pad 203. This design effectively prevents the rubber pad 204 from rotating.

[0035] Please see Figure 1 , Figure 3 and Figure 4 Each lifting rod 201 has a threaded top end, and each lifting rod 201 has a threaded mounting nut 6. The mounting nut 6 makes it easy for the user to install the lifting rod 201. The diameter of each lifting ring 202 is smaller than the diameter of the lifting rod 201, and the center of each lifting ring 202 is on the same reference plane as the center of the adjacent lifting rod 201. The above settings make it easy for the lifting rod 201 and the lifting ring 202 to pass through the reserved hole 101.

[0036] The bridge lifting point structure in this embodiment, through the combined use of the connecting component 2 set in the reserved hole 101, the lifting rod 201, the lifting ring 202, the steel pad 203, and the rubber pad 204, greatly enhances the connection stability between the upper and lower structures of the bridge. The design can effectively disperse and bear pressure during the lifting process, reduce relative displacement caused by weak connection, and thus avoid damage such as beam falling. The introduction of the reset plate 206, especially its multi-segment bent design, not only improves the reset performance of the rubber pad 204, but also provides additional seismic support for the bridge under extreme load conditions such as earthquakes. The setting of the rubber pad 204 plays a good protective role for the bridge body 1 during the lifting process. It can absorb and disperse the impact force generated during the lifting process, reduce direct damage to the structure of the bridge body 1, and thus extend the service life of the bridge.

[0037] It should be noted that after hoisting and positioning, C50 dry-hard shrinkage compensating concrete should be used to seal the hole, and waterproofing and protective layer construction should be carried out. When pouring concrete near the hoisting point, special attention should be paid to vibration to ensure the compactness of the concrete. Honeycombing and pitting should not occur at the hoisting point, and it is strictly forbidden for any pieces to fall off or the concrete to loosen.

[0038] The working principle of the above embodiment is as follows: The bridge lifting point structure includes a bridge body 1 and two sets of reserved holes 101 at both ends of the bridge body 1. Before the lifting begins, the lifting rod 201 needs to be inserted into the reserved hole 101. Since the top of the lifting rod 201 is designed with threads, the lifting rod 201 can be fixed by installing nuts 6 to ensure that it will not fall off during the lifting process. The lifting ring 202 is integrally formed with the lifting rod 201, which enhances the connection strength. When the sling or lifting device is connected to the lifting ring 202, the lifting ring 202 transmits the force to the lifting rod 201, and then distributes it to the bridge body 1 structure through the steel pad 203. During the lifting process, the rubber pad 204 plays an important buffering role. It can absorb and disperse the impact force generated during the lifting process, reducing direct damage to the bridge body 1 structure. The reset plate 206 is designed as an elastic steel sheet and is in a multi-segment bent shape. This design allows the rubber pad 204 to quickly return to its original position after being compressed, preventing plastic deformation caused by prolonged compression. Limiting rods 5 are fixedly connected to the bottom of the rubber pad 204, and these rods 5 interlock with the steel pad 203, effectively preventing the rubber pad 204 from rotating during hoisting. The combined use of the lifting rod 201, lifting ring 202, steel pad 203, and rubber pad 204 greatly enhances the connection stability between the upper and lower structures of the bridge. During hoisting, these components effectively distribute and bear pressure, reducing relative displacement caused by weak connections. The multi-segment bent design of the reset piece 206 not only improves the reset performance of the rubber pad 204 but also provides additional seismic support for the bridge under extreme load conditions such as earthquakes.
