[0015] The embodiments described herein are specific embodiments of the present invention and are used to illustrate the concept of the present invention.

In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the claims and the disclosure of the specification, including technical solutions that adopt any obvious substitutions and modifications to the embodiments described herein.

[0016] A bidirectional sliding isolation expansion joint installation system, such as Figures 1-3As shown, it includes a vertical sliding cover system 1 for buffering the impact of vertical seismic waves and a horizontal sliding cover system 2 for buffering the impact of horizontal seismic waves. The vertical sliding cover system 1 is extended along the length direction of the deformation joint; the vertical sliding cover system 1 and the horizontal sliding cover system 2 are hingedly connected to each other, and the overall area is adapted to the area of ​​the deformation joint.

The first transverse portion of the Z-type overlap joint 6 overlaps the base surface of the building structure on the side of the expansion joint.

[0017] The vertical sliding cover system 1 is a rectangular structure, the left side is hingedly connected to the horizontal sliding cover system 2, the right side and the upper side are sliding ends 8, and the lower side is hingedly connected to the base surface of the building structure on the side of the deformation joint. The horizontal sliding cover system 2 is a rectangular structure, the left side, the upper side and the lower side are sliding ends 8, and the right side is hingedly connected to the vertical sliding cover system 1. The length of the vertical sliding cover system 1 is much larger than the width of the horizontal sliding cover system 2. The length and width directions of the two are in the same direction, and the adjacent side panels that are hinged to each other are welded with 20mm thick stiffening plates.

[0018] The panel reinforcement structure 4 of the horizontal sliding cover system 2 is a stiffening rib arranged at intervals in the direction parallel to the extension direction of the deformation joint. The panel reinforcement structure 4 of the vertical sliding cover system 1 is a stiffening rib arranged at intervals in the direction perpendicular to the extension direction of the deformation joint. The stiffening ribs are connected between the side panels 5 on both sides and are steel bars made of galvanized steel plates. Anti-slip ribs 9 are provided between adjacent stiffening ribs. The anti-slip ribs 9 are made of steel bars with a diameter of 8 mm and are arranged vertically on the upper and lower sides or the left and right sides. The anti-slip ribs 9 should be set at a certain distance from the stiffening ribs.

[0019] The expansion joint is a horizontal expansion joint between building structures, and can also be a vertical expansion joint between upper and lower spacing structures. The vertical sliding cover system 1 is formed by welding a number of sliding cover units, that is, it is arranged along the length direction of the expansion joint.

[0020] A method for installing a bidirectional sliding seismic isolation deformation joint installation system includes the following steps: Step 1: The operator measures the actual size of the seismic joint on site and completes the order processing based on the overlap size according to the requirements of the design drawings.

[0021] Step 2: Using galvanized steel sheets of sufficient thickness as required by the design, the galvanized steel base plates of the vertical sliding cover plate system 1 and the horizontal sliding cover plate system 2 of the bidirectional sliding seismic isolation expansion joint installation system are processed and integrated with the stiffening ribs, Z-shaped overlaps 6 and anti-slip ribs 9 on the galvanized steel base plates; Step 3: On-site measurement and release of installation control lines and plate grid lines. First, install the vertical sliding cover plate 1 in the designated position and connect it to the building structure through the rotating shaft to achieve rotation. Similarly, install the vertical sliding cover plate 2, vertical sliding cover plate 3, and vertical sliding cover plate N in place in sequence. Adjacent vertical sliding cover plates are welded and reinforced to form a whole. Step 4: After all vertical sliding cover plates are installed, connect the horizontal sliding cover plate system 2 and the vertical sliding cover plate system 1 through the steering shaft to form a bidirectional sliding seismic isolation deformation joint system; Step 5: After the installation is completed, rotate and debug each cover system to ensure that its opening angle and sliding range meet the design requirements of sliding anti-deformation performance, and then use silicone weather-resistant sealant to seal the edge parts tightly with the building structure.

[0022] Step 6: Clean the galvanized steel plate base plate and complete the construction of the decorative surface layer at the deformation joint of the building structure. Use anti-slip ribs 9 to improve the integrity and firmness of the decorative surface layer and the galvanized steel plate base plate. Then use special flexible sealing caulking materials to fill the intersection of the deformation joint and the system.

[0023] In this application: the vertical sliding cover plate system and the horizontal sliding cover plate system, the two systems work together. When the structural part of the deformation joint of the building structure is impacted by a vertical earthquake wave, the vertical sliding cover plate system can be used to slide and cushion the impact to reduce the degree of damage to the building structure caused by the earthquake. When the structural part of the deformation joint of the building structure is impacted by a horizontal earthquake wave, the horizontal sliding cover plate system can be used to slide and cushion the impact to reduce the degree of damage to the building structure caused by the earthquake. At the same time, the vertical sliding cover plate system and the horizontal sliding cover plate system form a two-way sliding isolation deformation joint installation system, and the internal structure works together to achieve the anti-deformation function of the building deformation joint under complex earthquake conditions.

[0024] The vertical sliding cover system primarily utilizes galvanized steel sheets machined to the designed dimensions as the base plate for the expansion joint system. Vertical stiffening ribs are welded to the galvanized steel sheets at the designed spacing along the short sides. One side of the long side of the galvanized steel sheet is folded to form a vertical sliding end, and the other side of the galvanized steel sheet is connected to the vertical rotation axis. Horizontal anti-skid bars are welded to the galvanized steel sheet within each stiffening rib grid. The horizontal sliding cover system primarily utilizes galvanized steel sheets machined to the designed dimensions as the base plate for the expansion joint system. Horizontal stiffening ribs are welded to the galvanized steel sheets at the designed spacing along the short sides. The side of the long side of the galvanized steel sheet adjacent to the vertical sliding cover system is connected to the horizontal rotation axis, and the other side of the long side of the galvanized steel sheet is folded to form a horizontal sliding end. Vertical anti-skid bars are welded to the galvanized steel sheet within each stiffening rib grid.

[0025] When a building's expansion joint is impacted by vertical seismic waves, the vertical sliding cover system provides a sliding buffer, minimizing damage to the structure. When a building's expansion joint is impacted by horizontal seismic waves, the horizontal sliding cover system provides a sliding buffer, minimizing damage to the structure. The vertical and horizontal sliding cover systems together form a bidirectional sliding isolation expansion joint installation system. The internal structure works together to ensure the expansion joint resists deformation under complex seismic conditions. Galvanized steel laminates serve as the base plate for the expansion joint and also provide a flexible connection between adjacent building structures. Vertical and horizontal stiffeners reinforce the expansion joint system. The sliding end utilizes its own inclined surface to enable sliding under seismic loads, minimizing damage. The pivot axis articulates the vertical and horizontal sliding cover systems and the building structure, forming a unified whole and preventing rigid failure at weak points in the expansion joint. The anti-slip ribs mainly enhance the bonding and anti-slip properties between the expansion joint system and the upper decorative layer.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
