Description

Technical Field

[0001] This utility model relates to the field of horizontal force support technology, specifically to a large horizontal force support with a special tension-shear type anchor. Background Technology

[0002] Large bridges, offshore platforms, and high-rise buildings often require bearings during long-term service to transfer and distribute vertical and horizontal loads from the superstructure, as well as displacements and rotations caused by temperature changes. As a common structural form, large horizontal force bearings can withstand enormous vertical pressure while allowing a certain range of horizontal slippage to mitigate the impact of earthquakes, wind loads, or vehicle loads, thereby ensuring the overall safety and stability of the structure. However, existing horizontal force bearings still have shortcomings in terms of anchoring methods and force coordination.

[0003] Currently, most commonly used bearing anchoring methods rely on bolt connections, which involve pre-drilling bolt holes in the upper and lower anchor plates and then inserting bolts for fixation. While this method is technologically mature, it often presents challenges in space-constrained environments, especially in large bearings where a large number of high-strength bolts are required, leading to increased overall volume and construction complexity. Furthermore, bolt connections are prone to localized stress concentrations, which can cause loosening, fatigue, or bolt breakage under long-term load conditions, thus affecting the service life and safety of the bearing.

[0004] On the other hand, the anchors in existing supports are usually solid integral components, which lack reasonable stress dispersion paths when subjected to tensile and shear forces. Since tensile and shear forces act in different directions, when they act on the anchors simultaneously, excessive stress concentration often occurs at certain local locations, which can easily lead to crack initiation or fatigue failure. In addition, conventional material selection is mostly based on ordinary carbon steel, which has limited fatigue resistance and corrosion resistance, and performs poorly in humid, salt spray, or high-stress environments, making it difficult to meet the long-term use requirements of complex engineering environments.

[0005] In view of the above, this application proposes a large horizontal force support with special tension-shear type anchors to solve the problem. By optimizing the anchoring method, improving the geometry, and selecting high-performance alloy materials, it achieves the technical effects of high anchoring space utilization, reasonable tension-shear synergy, and stable and durable overall structure, thereby improving the overall performance and service life of the support.

[0028] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0030] This application proposes a large horizontal force support with a special tension-shear type anchor, as detailed below:

[0031] For reference Figure 1-3 This application mainly consists of a lower anchor plate 1, an upper anchor plate 2, an anchor 3, a steel basin 5, a piston plate 6, a sliding plate 7, and a central sliding guide rod 8. The anchor 3 is welded in the upper and lower anchor plates, which saves space and reduces costs compared to conventional bolt connections. At the same time, the geometric optimization (grooving) of the anchor 3 enables the mutual conversion of tensile and shear forces, reducing local stress.

[0032] For reference Figure 1 and Figure 3The lower anchor plate 1 has a first square groove on its downward side, and the upper anchor plate 2 has a second square groove on its upward side. By creating square grooves on the upper and lower anchor plates, a stable welding space is provided for the anchors. Compared with the traditional bolt hole arrangement, square groove welding can save installation space and reduce local stress concentration. Both the upper and lower anchor plates 1 are square in shape, and each of their surfaces has four square grooves, which are symmetrically distributed. An anchor 3 is welded into each square groove. The groove opening 4 can convert part of the tensile force into shear force during the stress process, thereby reducing local stress concentration in a single direction.

[0033] For reference Figure 1 There are multiple anchors 3, welded into the first and second square grooves. Each anchor 3 is cuboid in shape, with three layers of grooves 4 on its surface. Each layer has one groove on each of its four faces. The grooves 4 are concave square grooves, which are used to convert tensile and shear forces, reducing local stress. The square groove structure provides a good interlocking effect, improving tensile and shear resistance. This achieves a synergistic tensile-shear design, simplifying the process, reducing local stress, and decreasing structural size.

[0034] Furthermore, anchor 3 is made of AISI 4140 alloy steel, which boasts excellent strength and toughness, fatigue resistance, and corrosion resistance. Its use in anchors ensures high reliability, high strength, and durability, making it suitable for high-stress environments.

[0035] For reference Figure 1 The steel basin 5 is positioned on the upward side of the lower anchor plate 1, and its edge is fixed by bolts. The piston plate 6 is positioned in the middle of the steel basin 5, and its upward side has an inner groove. The sliding plate 7 is positioned on the downward side of the upper anchor plate 2, and its edge is fixed by bolts. The central sliding guide rod 8 is positioned in the middle of the sliding plate 7, with one side facing the piston plate 6 and inserted into the inner groove. The sliding plate 7 and the central sliding guide rod 8 together constrain the horizontal displacement of the support. The insertion of the central sliding guide rod 8 into the inner groove of the piston plate 6 ensures that no offset occurs during sliding, enabling the support to have horizontal mobility and reliable guidance, and preventing jamming. Furthermore, a second lubricating material 12 is provided in the inner cavity of the inner groove; adding lubricating material to the inner groove wall further reduces friction when the guide rod is inserted, enhances the sliding reliability of the central guide rod, and prevents dry friction.

[0036] The steel basin 5 and piston plate 6 constitute the typical load-bearing core of a basin bearing. The steel basin 5 bears vertical pressure, while the piston plate 6, through its inner groove and central sliding guide rod 8, constrains rotation and displacement. This ensures the bearing's high load-bearing capacity and stable sliding performance, while also providing an installation basis for subsequent lubrication design.

[0037] For reference Figure 1A PTFE plate 9 is provided between the steel basin 5 and the piston plate 6. PTFE has an extremely low coefficient of friction and good wear resistance. When placed between the steel basin and the piston plate, it can significantly reduce frictional resistance, thereby improving the flexibility and durability of sliding, and reducing energy consumption and wear.

[0038] For reference Figure 2-3 A stop 10 is provided on the top of the piston plate 6, and a first lubricating material 11 is provided on the side of the stop 10 via rivets. The stop 10 is located on the top side of the piston plate 6, and the first lubricating material 11 is provided to reduce friction when the support rotates or undergoes relative displacement. It should be noted that the first lubricating material 11 and the second lubricating material 12 are both of type DU-B, which is an existing self-lubricating composite material with good wear resistance.

[0039] For reference Figure 1 A stainless steel plate 13 is provided on the downward side of the sliding plate 7 and the central sliding guide rod 8. The stainless steel plate is used as the sliding pair material, in conjunction with the first lubricating material 11 and the second lubricating material 12, to ensure corrosion resistance and wear resistance; effectively improving the overall corrosion resistance and long-term stability of the support.

[0040] In this invention, the working steps of the device are as follows:

[0041] First, prepare the lower anchor plate 1 and the upper anchor plate 2, and open the first square groove and the second square groove on their surfaces respectively; then, embed multiple cuboid anchors 3 into the first square groove and the second square groove in sequence, and fix them by welding to firmly connect them to the upper and lower anchor plates; since the surface of the anchor 3 is provided with three layers of grooves 4, a stable tensile-shear cooperative structure can be formed after welding, thereby improving the tensile and shear resistance.

[0042] Then, a steel basin 5 is installed on the upper side of the lower anchor plate 1 and its edge is fixed with bolts to ensure that the steel basin 5 is in a stable stress state. Next, the piston plate 6 is placed in the middle of the steel basin 5 and the second lubricating material 12 is injected into the inner groove reserved on its upper side to reduce friction when the guide rod slides later. At the same time, a sliding plate 7 is fixedly installed on the lower side of the upper anchor plate 2, and the middle opening of the sliding plate 7 is aligned with the central sliding guide rod 8.

[0043] Next, the central sliding guide rod 8 is inserted downward from the middle of the sliding plate 7 into the inner groove of the piston plate 6, so that the central sliding guide rod 8 achieves sliding engagement in the inner groove; at this time, the second lubricating material 12 in the inner groove can significantly reduce the friction between the guide rod and the groove wall, ensuring the flexibility and reliability of the guide rod during horizontal displacement.

[0044] Subsequently, a PTFE plate 9 is laid between the steel basin 5 and the piston plate 6. Utilizing its extremely low coefficient of friction and good wear resistance, the friction between the piston plate 6 and the steel basin 5 is further reduced, thereby improving the overall sliding performance and service life of the support.

[0045] Then, a stop block 10 is installed on the top of the piston plate 6, and the first lubricating material 11 is fixed on the side of the stop block 10 by rivets; in this way, when the support is running or relative displacement occurs, the first lubricating material 11 can continuously provide lubrication and further reduce friction; it should be noted that the first lubricating material 11 and the second lubricating material 12 are both DU-B type composite self-lubricating materials, which can ensure wear resistance for a long time.

[0046] Finally, a stainless steel plate 13 is installed at the connection between the sliding plate 7 and the central sliding guide rod 8, so that the stainless steel plate can be used in conjunction with the first lubricating material 11 and the second lubricating material 12. While ensuring low friction operation, it further improves the corrosion resistance and wear resistance, thereby ensuring the stability and reliability of the support in the long-term working environment.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
