Description

Technical Field

[0001] This utility model relates to the field of bridge technology, specifically to a support structure for building construction. Background Technology

[0002] A bearing is a connecting device between a bridge beam and a pier. It is a component that connects the superstructure and the substructure. Its function is to transfer the load from the superstructure, control the displacement of the superstructure, and release the rotational constraints of the superstructure. The substructure is usually made of concrete. It is cast together with the lower bearing plate assembly using gravity grouting. The grouting requirement is to grout from the center of the bearing outwards until it is full. After grouting, the bearing and the substructure should be tightly fitted without any gaps.

[0003] However, in reality, the unevenness of the steel plate itself, the cumulative flatness during processing and assembly, the lack of strict control over the support installation process, insufficient vibration during grouting, and poor air venting are all factors that cause the lower support plate to become detached, thereby affecting the stability and service life of the structure.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] It should be noted that the building construction support structure described in this utility model is used in, but not limited to, the field of bridges. For ease of explanation, this utility model only uses the application of the building construction support structure in the field of bridges as an example. The principle of the building construction support structure applied to other types of equipment is essentially the same as that applied to the field of bridges, and will not be described in detail here.

[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of a building construction support structure according to an embodiment of the present invention. The building construction support structure includes:

[0027] The upper support assembly 1 includes a bottom anchor steel plate 11, an upper support plate 12, and an upper anchor device 13; the lower end of the bottom anchor steel plate 11 is provided with the upper support plate 12, and the upper anchor device 13 passes through the upper support plate 12 and the bottom anchor steel plate 11 in sequence and is connected to the bridge.

[0028] The middle support plate 2 is located at the lower end of the upper support plate 12 and is used to transmit force and provide rotation or bearing function.

[0029] The lower support assembly 3 includes a boss 31, a lower support plate 32, and a lower anchor device 33. The boss 31 is located below the middle support plate 2, and the lower support plate 32 is provided on the boss 31. The lower anchor device 33 passes through the boss 31 and is connected to the pier.

[0030] In this embodiment, compared with the prior art, this device can improve connection reliability and enhance anchoring strength by setting the bottom anchor steel plate 11, the upper support plate 12 and the upper anchor device 13. Furthermore, by setting the middle support plate 2, it can achieve effective force transmission and structural layer management. The boss 31, the lower support plate 32 and the anchor device can enhance its bearing capacity. Moreover, the device is modular in design, which facilitates on-site installation or disassembly. At the same time, the subsequent maintenance cost is low, effectively reducing subsequent maintenance costs.

[0031] In one embodiment, please refer to Figures 1-4 To improve the working efficiency of the spherical crown liner 21, the middle support plate 2 includes the spherical crown liner 21, which is a convex spherical metal table. The spherical crown liner 21 is movably disposed between the upper support plate 12 and the lower support plate 32.

[0032] In this embodiment, the spherical cap liner 21 is a metal spherical table with a convex spherical surface. This shape allows it to rotate slightly when subjected to pressure from the upper and lower support plates 32, thereby accommodating the small displacements or rotations of the superstructure caused by factors such as temperature changes and loads. The spherical cap liner 21 and the upper and lower support plates 32 are ground together using a low-friction coefficient wear-resistant plate, stainless steel plate, or coating. This design ensures low frictional resistance even under vertical forces, allowing the support to freely make small rotational adjustments when necessary without damage or excessive wear due to excessive friction. The spherical cap liner 21 can effectively transfer the vertical load from the bridge to the piers while allowing a certain degree of rotational freedom. This means that without affecting the overall structural stability, the spherical cap liner 21 can alleviate the deformation requirements of the superstructure caused by temperature changes, earthquakes, or other dynamic loads. This reduces stress concentration problems caused by improper constraints. The spherical cap liner 21, as the intermediate support plate 2, allows the support to rotate freely within a certain range. This greatly improves the overall structure's adaptability to environmental changes, such as thermal expansion and contraction caused by temperature changes, dynamic loads such as vehicle vibration, wind effects, and geological activities such as minor earthquakes. Because the spherical cap liner 21 can effectively disperse and regulate the small displacements and rotations caused by various factors, it avoids stress concentration caused by rigid connections, thereby reducing the possibility of material fatigue and helping to extend the service life of the support and even the entire bridge or building. The spherical cap liner 21 can provide the necessary rotational freedom while ensuring vertical bearing capacity. Especially in the face of natural disasters such as earthquakes, this characteristic can help reduce the degree of structural damage and protect the safety of people's lives and property. The application of the spherical cap liner 21 simplifies the installation requirements during construction and is also due to its good self-adaptability.

[0033] In one embodiment, please refer to Figures 1-4 To improve the working efficiency of the rubber bearing block 22, the rubber bearing block 22 is movably positioned between the upper support plate 12 and the lower support plate 32.

[0034] In this embodiment, when the rubber bearing block 22 is used as the middle support plate 2 component, its working principle mainly relies on the unique properties of rubber materials, including elasticity, compressibility, and durability. When the rubber bearing block 22 is subjected to pressure from the bridge and vertical loads transmitted through the upper support plate 12, it will deform. This deformation is elastic deformation, which can effectively absorb and disperse energy. This means that under dynamic loads, such as vibrations caused by vehicle movement, wind, or earthquakes, the rubber bearing block 22 can act as a buffer, reducing the impact on the entire structure. Because rubber has good elasticity and a certain degree of plasticity, the rubber bearing block 22 can automatically adjust its shape within a certain range to adapt to the small displacement or rotation requirements between the upper and lower support plates 32. Therefore, even if there are slight deviations after installation under non-ideal conditions or long-term use, the rubber bearing block 22 can self-adjust to ensure continuous and stable support. The rubber bearing block 22, movably positioned between the upper support plate 12 and the lower support plate 32, is not completely fixed but allows for a certain degree of relative movement. This design not only helps alleviate structural stress concentration caused by factors such as temperature changes and settlement but also improves the overall structural flexibility and seismic resistance. The elastic support provided by the rubber bearing block 22 effectively reduces vibration transmission, improves driving comfort, and is crucial for protecting bridges or other structures from damage caused by frequent vibrations, thereby improving the overall structural safety. The excellent properties of the rubber material itself, combined with the reasonable structural design, enable the rubber bearing block 22 to maintain efficient operation over a long period of time, reducing the frequency of maintenance due to fatigue damage and extending the service life of the support and even the entire structure. Compared to other complex mechanical devices, the rubber bearing block 22 is easy to install and replace.

[0035] In one embodiment, please refer to Figure 5 When the lower surface of the lower support plate 32 is a conical panel 321, the lower surface of the lower support plate 32 is provided with a conical panel 321 composed of multiple inclined surfaces.

[0036] In this embodiment, the conical panel 321, composed of multiple inclined surfaces, increases the contact area between the lower support plate 32 and the pier. This helps to distribute the load from the superstructure more evenly, reducing local stress concentration and thus improving the overall structural safety and stability. During gravity grouting, the conical panel 321 guides the cement grout to better fill all the gaps at the bottom of the support. Especially when grout venting holes are added, air can be effectively expelled, preventing the formation of air bubbles and ensuring dense grouting without voids. This further enhances the bond strength and integrity between the support and the substructure. Since there may be some errors or uneven ground during actual construction, the design of the conical panel 321 allows the support to automatically adjust to the optimal position, ensuring good contact even on slightly inclined ground and improving the tolerance during installation. Its unique geometry disperses horizontal shear forces over a larger area, reducing the risk of excessive stress at a single point and enhancing shear resistance. The conical panel 321 further improves structural stability by increasing the contact area and ensuring grouting quality, reducing structural instability caused by support detachment and enhancing the overall safety of the bridge or structure. Good grout density and uniform load distribution reduce the possibility of material fatigue, helping to extend the service life of the supports and the entire structure. The design of the conical panel 321 takes into account practical problems that may be encountered on construction sites, such as uneven ground and limited operating space, making installation simpler and faster, reducing construction difficulty and technical requirements. The conical panel 321 can, to some extent, mitigate the impact of earthquakes or other dynamic loads, improving the structure's seismic resistance and durability by rationally dispersing horizontal shear forces.

[0037] In one embodiment, please refer to Figure 6 When the lower surface of the lower support plate 32 is a wedge-shaped panel body 322, the lower surface of the lower support plate 32 is provided with a wedge-shaped panel body 322 composed of two inclined surfaces.

[0038] In this embodiment, although the wedge-shaped panel 322 consists of only two inclined surfaces, it can still effectively increase the actual contact area between the support and the pier compared to a flat bottom plate. This design helps to distribute the load from the superstructure more evenly, reduce local stress concentration, and thus improve the safety and stability of the overall structure. The design of the wedge-shaped panel 322 is conducive to guiding the cement grout to fill all the gaps at the bottom of the support better. Especially when gravity grouting is performed, it can effectively expel air and avoid the formation of air bubbles. This ensures the compactness of the grout, reduces the possibility of voids, and enhances the bond strength and integrity between the support and the substructure. In actual construction, the ground may be uneven. The wedge-shaped panel 322 allows the support to automatically adjust to the optimal position according to the actual situation, ensuring good contact even on slightly inclined ground, and improving the fault tolerance during installation. The wedge-shaped panel 322, through its unique geometry, can distribute horizontal shear forces over a larger area, reducing the risk of excessive stress at a single point and enhancing shear resistance. The wedge-shaped panel 322 can, to some extent, mitigate the impact forces caused by earthquakes or other dynamic loads. By reasonably dispersing horizontal shear forces, it improves the seismic resistance and durability of the structure.

[0039] In one embodiment, please refer to Figure 7 Several grouting ports 323 are also provided on the lower support plate 32.

[0040] In this embodiment, the grouting port 323 is designed primarily to guide cement grout or other grouting materials into the gap between the bottom of the bearing and the substructure, ensuring that these areas are fully filled. By rationally arranging multiple grouting ports 323, the flow direction and speed of the grouting material can be effectively controlled, avoiding local voids or air bubbles. During the grouting process, air often gets trapped between the bottom of the bearing and the substructure, forming air bubbles. This not only affects the grout density but may also lead to problems such as bearing detachment. The grouting port 323 helps to expel these gases, allowing the grouting material to adhere more tightly to the contact surface, ensuring no detachment. Through the action of multiple grouting ports 323, the grouting material can be more evenly distributed across the entire contact surface, thereby effectively filling the gap between the bottom of the bearing and the pier, ensuring a tight bond between the two, and enhancing the integrity and stability of the structure. Setting multiple grouting ports 323 allows for flexible adjustment of the grouting position according to the actual site conditions, simplifying the construction process and improving work efficiency. It also provides convenient conditions when secondary grouting is required. The grouting port 323 helps to ensure... Ensuring that cement grout or other grouting materials can fully fill all voids at the bottom of the bearing reduces the problem of voids caused by air bubbles or incomplete filling, thereby improving the quality of grouting. By eliminating potential air bubbles and incompletely filled areas, the bond strength between the bearing and the substructure is enhanced, improving the stability and safety of the entire structure. Good grout density reduces damage caused by minor movements or settlements that may occur during long-term use, extending the service life of the bearing and its related structures. The presence of multiple grouting ports 323 provides construction personnel with more choices and flexibility, allowing them to adjust the grouting strategy according to actual needs, reducing construction difficulty and technical requirements. Because the grouting quality is guaranteed, the cost of subsequent maintenance and repair is reduced. In addition, the efficient grouting process also helps save time and labor costs, making it an economical and effective solution in the long run. When facing complex geological conditions or irregular foundation surfaces, multiple grouting ports 323 can better cope with various challenges, ensuring that the bearing can be firmly fixed in the predetermined position, improving the adaptability and reliability of the project.

[0041] To better understand this utility model, the following is combined with... Figures 1 to 7The technical solution of this utility model is described in detail below: A shear-resistant device is provided between the boss 31 and the lower support plate 32. This shear-resistant device includes vertical stiffening ribs or steel plates added between the boss 31 and the lower support plate 32 to enhance shear resistance. These stiffening ribs or steel plates can be welded or bolted to the boss 31 and the lower support plate 32 to form an integral structure. The upper anchorage device 13 in this application includes high-strength bolts, anchor rods, or other types of fasteners, ensuring that the support can withstand and transmit vertical loads and possible horizontal forces from above. The lower anchorage device 33 includes pre-embedded reinforcing bars, chemical anchors, expansion bolts, and other fasteners. The lower anchorage device 33 ensures that the support can reliably attach to the bridge pier. This effectively transfers the load from the bridge. Simultaneously, under earthquakes or other dynamic loads, it possesses a certain shear resistance, preventing slippage or detachment of the support. The upper anchorage device 13 firmly fixes the support to the bridge, preventing displacement or detachment. The design of the bottom anchorage steel plate 11 and the upper support plate 12 enhances the reliability of the connection and improves the overall structural stability. The middle support plate 2 can be a spherical crown liner 21 or a rubber bearing block 22, selected according to the specific application scenario. The spherical crown liner 21 is a metal spherical platform with a convex spherical surface, movably positioned between the upper support plate 12 and the lower support plate 32. The spherical crown liner 21 allows the support to rotate slightly under the pressure of the upper and lower support plates 32, adapting to temperature changes, load effects, etc. The small displacement or rotation caused by the element is rubbed against the upper and lower support plates 32 using wear-resistant plates with a low coefficient of friction (such as stainless steel plates or coatings). This ensures low frictional resistance even under vertical forces, allowing the support to freely make small rotational adjustments when necessary, avoiding damage or excessive wear due to excessive friction. The rubber bearing block 22 is an elastic and compressible material, movably positioned between the upper support plate 12 and the lower support plate 32. When subjected to vertical loads from the bridge, the rubber bearing block 22 undergoes elastic deformation, absorbing and dispersing energy, thus acting as a buffer. Due to the good elasticity and certain plasticity of the rubber material, the rubber bearing block 22 can automatically adjust its shape within a certain range to adapt to the upper and lower supports. The need for minute displacements or rotations between plates 32 ensures continuous and stable support. Shear-resistant devices, such as stiffening ribs or steel plates, between the boss 31 and the lower support plate 32 enhance their shear resistance, ensuring the support does not slip relative to each other under horizontal shear forces. The design of the tapered or wedge-shaped panel 321 increases the contact area between the lower support plate 32 and the pier, helping to distribute loads from the superstructure more evenly, reducing localized stress concentration, and improving the overall structural safety and stability. Multiple grouting ports 323 guide cement grout or other grouting materials into the gaps between the bottom of the support and the substructure, ensuring these areas are fully filled, preventing air bubbles, and ensuring dense, void-free grouting.Enhance the bond strength and overall integrity between the support and the substructure.
