Description

Technical Field

[0001] The utility model relates to the technical field of anti-deformation of construction engineering, and more specifically to a curved surface ball sliding structure of a floor deformation joint. Background Art

[0002] For deformation joints on floors or ground, the traditional construction method is to achieve energy dissipation and shock reduction through seismic spring structures to achieve anti-deformation effects, which can meet the needs of covering the deformation joints of buildings and play a decorative role. The seismic spring structure is equipped with a base for seismic springs, the center of which is connected to the expansion joint and the settlement through a central control slide rod and a central screw. The seismic displacement is mainly completed by the diagonally placed 45° central control slide rod and seismic spring.

[0003] The traditional construction method has certain disadvantages:

[0004] 1. Since the traditional structure is not an integral structure, it needs to be installed step by step during installation. Therefore, there are deformation and dislocation of components during the installation of the expansion joint. In addition, improper installation is prone to slippage and dislocation. The installation accuracy of the seismic expansion joint decorative panel has a great impact on its service life.

[0005] 2. Due to the low probability and great hidden danger of earthquake action, the building itself also has the local phenomenon of uneven settlement. Since the spring itself has the self-vibration phenomenon, it is easy to transmit low-frequency vibration and be affected by people, thereby increasing the vibration response of its seismic structure. When the natural vibration frequency of the structure is close to the frequency of the low-frequency vibration of the atmosphere, it is easy to produce resonance inside the structure, thereby increasing the vibration response of the structure and causing the ground at the deformation joint to be uneven;

[0006] 3. At present, the market price of this kind of product is relatively high, and on-site construction usually involves purchasing simple expansion joint decorative panels, which cannot truly achieve the purpose of earthquake resistance and damage prevention.

[0007] In view of the above situation, the utility model proposes a curved ball sliding structure for floor deformation joints, which can achieve overall installation, improve durability, and have controllable energy dissipation and shock absorption capabilities and good self-resetting functions, greatly enriching the floor or ground deformation joint structure, thereby providing a safe and reliable deformation joint device. Utility Model Content

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a floor deformation joint curved surface ball sliding structure, comprising a concrete structure and a deformation joint on the surface of the concrete structure, the surface of the concrete structure is provided with two lower base plates, and an upper sliding panel is jointly installed on the top of the two lower base plates, a plurality of spherical grooves are provided on the lower surface of the upper sliding panel and the upper surface of the lower base plate, and balls are embedded in the interior of the plurality of spherical grooves, and a sliding damping paint is applied on the curved surface on which the balls slide.

[0010] It can be understood that the structure specifically includes a lower base plate, a ball and an upper sliding panel, and a sliding damping paint is applied on the curved surface on which the ball slides, thereby forming a curved surface friction sliding structure.

[0011] Preferably, the upper sliding panel and the lower base plate are both made of stainless steel, and a finishing layer is reserved on the surface of the upper sliding panel. The upper sliding panel and the lower base plate are made of stainless steel and have high load-bearing and deformation resistance capabilities to meet the use requirements of normal aisles, and the finishing layer can be installed with floor tiles, wooden boards and other floor decoration materials according to specific needs.

[0012] Preferably, the bottom of the upper sliding panel is integrally formed with two curved heads, and the surfaces of the two lower base plates are provided with arc grooves that are compatible with the curved head structure. The curved heads are located inside the arc grooves, and the lower surfaces of the curved heads are smooth curved surfaces. The two curved heads at the bottom of the upper sliding panel can be located inside the arc grooves opened by the lower base plate, making it convenient for the subsequent balls to roll inside the spherical grooves.

[0013] Preferably, multiple spherical grooves are equidistantly distributed in a circular shape on the lower surface of the curved head belonging to the upper sliding panel and inside the arc groove opened on the lower base plate. The two ends of the ball are rollingly connected inside the corresponding spherical grooves. The ball can roll inside the spherical groove. The rolling direction is not restricted and it can roll in all directions. Moreover, under the action of an earthquake, the rolling of the ball can achieve seismic isolation and uneven settlement, and can automatically reset.

[0014] Preferably, the concrete structure is provided with a floor thickness layer on one side of the lower base plate, and a rubber decorative strip is filled between the floor thickness layer and the upper sliding panel. The deformation joint curved ball sliding structure can be customized according to the thickness of the floor thickness layer. After the overall construction is completed, a rubber decorative strip is used to fill the space between the floor thickness layer and the upper sliding panel to achieve an aesthetic and grid-dividing effect.

[0015] Preferably, the sliding damping paint is a deformable fluid, the purpose of which is to improve the energy dissipation capacity.

[0016] Technical effects and advantages of the utility model:

[0017] When the utility model is in use, under the influence of earthquake or uneven settlement, due to the existence of the ball, when the building body produces relative displacement during deformation, the rolling friction resistance is first overcome, and the ball rolls in the spherical groove; at the same time, the sliding damping paint adheres to the surface of the ball and the rolling path, and is squeezed by the ball to produce deformation, thereby improving the damping and energy dissipation capabilities; after the earthquake or settlement stabilizes, local pressure can be manually performed, which also overcomes the rolling friction resistance and produces self-reset, and can be installed as a whole, thereby improving durability, and having controllable energy dissipation and shock absorption capabilities and good self-reset functions.
