Abstract
Description
Technical Field
[0001] This utility model specifically relates to a shear-resistant elastic support for building heated corridors, belonging to the field of building heated corridors. Background Technology
[0002] Flexible bearings are commonly used in the construction of heated corridors in buildings, offering several advantages. Firstly, they possess excellent seismic isolation and damping performance, effectively absorbing and dissipating seismic energy, significantly reducing the impact of earthquakes on the corridor and adjacent buildings, and protecting structural safety. Secondly, their good elasticity allows them to adapt to horizontal displacement and rotation caused by temperature changes, wind loads, and other factors, ensuring structural stability. Furthermore, flexible bearings have a simple structure, are easy to construct, and are relatively easy to install and replace, reducing construction difficulty and maintenance costs. Simultaneously, the raw materials for flexible bearings are readily available, resulting in a relatively low overall cost and high cost-effectiveness. These advantages make flexible bearings a promising candidate for widespread application in heated corridors.
[0003] The forces applied to rubber bearings in building heated corridors are mainly in the vertical and horizontal directions:
[0004] The vertical force primarily originates from the self-weight of the building's heated corridor, with the elastic material of the elastic support mainly bearing compressive forces. Due to the excellent elasticity of rubber, it can undergo compressive deformation under vertical pressure while maintaining sufficient stiffness to support the weight of the superstructure. Its vertical load-bearing capacity depends mainly on the thickness and number of layers of the elastic material, as well as its combination with the steel plate. Generally, the elastic material exhibits high stiffness under vertical compression, enabling it to withstand larger vertical loads.
[0005] The horizontal forces primarily originate from lateral wind loads acting on the building's heated corridor, which in turn act on the rubber bearings. The elastic material of the elastic bearings mainly bears shear forces. Elasticity is relatively flexible in the horizontal direction, possessing a large shear deformation capacity, capable of accommodating horizontal displacement of the structure. Its horizontal load-bearing capacity is much smaller than its vertical load-bearing capacity; it mainly transmits and dissipates horizontal forces through elastic shear deformation. This design allows the elastic bearings to permit a certain degree of structural displacement under horizontal forces, thus playing a role in vibration reduction and buffering.
[0006] Because elastic materials exhibit different mechanical properties under vertical compression and horizontal shear, the magnitude of the force they can withstand in the vertical and horizontal directions also differs. Vertical load-bearing capacity is primarily reflected in the elastic compressive stiffness, while horizontal load-bearing capacity is reflected in the elastic shear stiffness. Generally, the compressive stiffness of an elastic material is much greater than its shear stiffness; therefore, elastic supports can withstand greater forces in the vertical direction, while in the horizontal direction they primarily adapt to the force through deformation rather than directly bearing a larger force.
[0007] This can lead to fatigue damage, performance degradation, and localized damage in elastic materials. Long-term, repeated deformation can cause microcracks within the elastic material, reducing its elastic modulus and durability, and may also induce stress concentration, resulting in localized tearing or cracking. These changes weaken the support's horizontal displacement capacity, vertical load-bearing capacity, and seismic performance, increasing the need for maintenance and replacement.

Detailed Implementation
[0032] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0033] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 This embodiment describes a shear-resistant elastic support for a building's heated corridor, comprising a top plate 1, a bottom plate 2, and an elastic assembly 3. The lower end of the top plate 1 is positioned at the upper end of the elastic assembly 3, and the lower end of the elastic assembly 3 is positioned at the upper end of the bottom plate 2. The elastic assembly 3 includes a first elastic body 3-1, a track component 3-2, a second elastic body 3-3, a sliding component 3-4, and a strip component 3-5. The lower end of the first elastic body 3-1 is positioned at the upper end of the bottom plate 2, and the upper end of the first elastic body 3-1... The first strip groove 3-1-1 is machined at the end, and a track component 3-2 is provided in the first strip groove 3-1-1. A T-shaped slide groove 3-2-1 is machined at the upper end of the track component 3-2. A slide component 3-4 is slidably arranged in the T-shaped slide groove 3-2-1. The slide component 3-4 is located at the lower end of the strip component 3-5. The upper end of the second elastic body 3-3 is located at the lower end of the top plate 1. A second strip groove 3-3-1 is machined at the lower end of the second elastic body 3-3. A strip component 3-5 is provided in the second strip groove 3-3-1.
[0034] When the present invention is subjected to a horizontal shear force, the slider 3-4 is displaced within the T-shaped groove 3-2-1, thereby enabling the first elastic body 3-1 and the second elastic body 3-3 to be misaligned when dealing with the horizontal shear force, thus mitigating the problems of fatigue damage, performance degradation, and local damage caused by the horizontal shear force to the elastic assembly 3.
[0035] The strip 3-5 is set in the second strip groove 3-3-1, and the track 3-2 is set in the first strip groove 3-1-1, so that the first elastic body 3-1 and the second elastic body 3-3 can effectively contact each other, thus not affecting the compressive force borne in the vertical direction.
[0036] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. A plurality of first elastic rods 3-6 are inserted between the first elastic body 3-1 and the second elastic body 3-3. A plurality of first slots 3-3-2 are machined along the circumference of the lower end of the second elastic body 3-3. A plurality of second slots 3-1-2 are machined along the circumference of the upper end of the first elastic body 3-1. The first slots 3-3-2 and the second slots 3-1-2 are arranged in a one-to-one correspondence. One end of each first elastic rod 3-6 is inserted into its corresponding first slot 3-3-2, and the other end of each first elastic rod 3-6 is inserted into its corresponding second slot 3-1-2. The first elastic rods 3-6 and the first slots 3-3-2 are arranged in a one-to-one correspondence.
[0037] When the present invention is subjected to horizontal shear force, the first elastic body 3-1 and the second elastic body 3-3 are subjected to vertical force and squeezed together. At the same time, when subjected to horizontal force, the contact surface of the first elastic body 3-1 and the second elastic body 3-3 will be subjected to large friction force, which can easily cause fatigue damage and local damage to the contact surface. The multiple first elastic rods 3-6 can alleviate the problem of contact surface damage of the first elastic body 3-1 and the second elastic body 3-3 caused by the above problems, while increasing the shear resistance.
[0038] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. The upper end of the base plate 2 is provided with a plurality of first insert rods 4, and the lower end of the first elastic body 3-1 is processed with a plurality of third slots 3-1-3. The first insert rods 4 and the third slots 3-1-3 are arranged in a one-to-one correspondence. Each first insert rod 4 passes through its corresponding third slot 3-1-3. The lower end of the top plate 1 is provided with a plurality of second insert rods 5, and the upper end of the second elastic body 3-3 is provided with a plurality of fourth slots 3-3-3. The fourth slots 3-3-3 and the second insert rods 5 are arranged in a one-to-one correspondence. Each second insert rod 5 passes through its corresponding fourth slot 3-3-3.
[0039] When the present invention is subjected to horizontal shearing force, since multiple first inserts 4 and multiple second inserts 5 are respectively inserted into multiple third slots 3-1-3 and multiple fourth slots 3-3-3, when the first elastic body 3-1 and the second elastic body 3-3 are horizontally misaligned, the first inserts 4 can relieve the shearing force at the contact position between the bottom plate 2 and the first elastic body 3-1, and the second inserts 5 can relieve the shearing force at the contact position between the top plate 1 and the second elastic body 3-3.
[0040] Specific Implementation Method Four: This implementation method further defines Specific Implementation Methods One, Two, or Three. The elastic assembly 3 is replaced by an elastic element 6. The elastic element 6 includes a flat cylinder 6-1 and two sliding plates 6-2. Each end of the flat cylinder 6-1 has a mounting groove 6-1-1, and each mounting groove 6-1-1 contains a sliding plate 6-2. One end of each sliding plate 6-2 has a sliding groove 6-2-1. A first slider 1-1 is located at the lower end of the top plate 1 and slides within its corresponding sliding groove 6-2-1. A second slider 2-1 is located at the upper end of the bottom plate 2 and slides within its corresponding sliding groove 6-2-1. The transverse cross-sectional shape of the flat cylinder 6-1 along its thickness direction is elliptical.
[0041] When the present invention is subjected to horizontal shear force, the first slider 1-1 slides in its corresponding sliding groove 6-2-1, and the second slider 2-1 slides in its corresponding sliding groove 6-2-1, thereby adapting to the horizontal displacement of the structure and avoiding fatigue damage, performance degradation and local damage to the elastic element 6. At the same time, the elastic element 6 is an integral part and can withstand a large vertical load.
[0042] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3 or 4, and the elastic assembly 3 is a rubber assembly.
[0043] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four or Five. The shape of the sliding groove 6-2-1 is a long strip. The length of the sliding groove 6-2-1 is less than or equal to half the length of the flat cylinder 6-1. The length direction of the sliding groove 6-2-1 is in the same direction as the length direction of the flat cylinder 6-1.
[0044] Working principle:
[0045] During the construction of the heated corridor 7, this utility model is installed between the heated corridor 7 and the supporting pier 8. Since the sliding member 3-4 is located within the T-shaped sliding groove 3-2-1, when the device is subjected to horizontal shear force, the sliding member 3-4 can slide freely within the T-shaped sliding groove 3-2-1. This allows the structure to effectively adapt to horizontal displacement, thereby significantly reducing the risk of fatigue damage, performance degradation, and localized damage to the first elastic body 3-1 and the second elastic body 3-3 due to long-term stress.
[0046] Furthermore, the first elastic body 3-1 and the second elastic body 3-3 are vertically arranged sequentially between the top plate 1 and the bottom plate 2, forming a stable vertical support structure. This ensures that the device maintains good stability and load-bearing capacity when subjected to large vertical loads.
