Embodiment 1

[0042] This embodiment is a large public building, the maximum displacement during the earthquake is calculated to be 500mm, so the width of the isolation joint is 1000mm. The seismic isolation joint is set on one side of the stairwell, and the building components on both sides of the seismic isolation joint are the outer wall with insulation layer and its outer decorative surface. The portal curtain wall includes connecting keels 2a and exterior decorative panels, and the decorative panels are imitation wood curtain walls. The thickness of the portal curtain wall is 250, so it is necessary to divide the portal curtain wall into two sections, and the movable section is suitable for deformation. The width of the portal curtain wall is g=1650mm (including a small section), which is wider than the seismic isolation joint, and the portal curtain wall is close to the column, so there will be no reverse deformation, so the interior of the seismic isolation joint 1 is not made on the...

Embodiment 2

[0055] see Figure 8 As shown, this embodiment is a large-scale public building, and its maximum displacement during earthquake is calculated to be 500mm, so the width of the seismic isolation joint is 1000mm. The seismic isolation joint is set in the public activity area, so a small room is set up independently outside the seismic isolation joint to solve the problems of heat preservation and fire prevention.

[0056] The exterior facade is veneered brick veneer, and its thickness is 50mm. The width of the portal curtain wall is f=1250mm. The specific design is different from Embodiment 1 in that, in order to prevent reverse deformation, an independent curtain wall guide plate 6 is provided. The back side of the curtain wall guide plate 6 is provided with a back supporting keel 15 .

[0057] After the use of the present invention, the original h=1000mm wide seismic isolation joint is converted into two e=20mm and d=8mm wide narrow joints, and the material of the seismic is...

Embodiment 3

[0059] see Figure 9-13 As shown, this embodiment is a large-scale public building, and its maximum displacement during earthquake is calculated to be 500mm, so the width of the seismic isolation joint is 1000mm. The seismic isolation joint is set in the public activity area, so a small room is set up independently outside the seismic isolation joint to solve the problems of heat preservation and fire prevention. In order to prevent reverse deformation, an independent curtain wall guide plate 6 is provided. One end of the curtain wall guide plate 6 extends into the seismic sliding joint 9, and a rubber pad 17 is provided between the door curtain wall 2, and the other end of the curtain wall guide plate 6 is connected with the building components in the deformation joint. The back side of 6 is provided with back supporting keel 15.

[0060] Different from Embodiments 1 and 2, a limit spring 10 is provided on the inner side of the door curtain wall 2 and inside the seismic iso...

Abstract

Provided are a facade seismic isolation gap device used for a seismic isolation building and a construction method thereof. The facade seismic isolation gap device used for a seismic isolation building is arranged on the outer side of a seismic isolation gap and is wider than the seismic isolation gap. The seismic isolation gas device comprises a gate-type curtain wall, a connecting end frame, a free end frame, curtain wall elastic reset elements, and curtain wall guide plate s. The end face of the free end frame, close to the free end of the gate-type curtain wall, is a first sliding surface. The free end of the gate-type curtain wall is provided with a second sliding surface. The shape of the second sliding surface is adapted to the shape of the first sliding surface. A seismic sliding joint is reserved between the two sliding surfaces. The connecting end of the gate-type curtain wall is hinged with the connecting end frame through the curtain wall elastic reset elements. The curtain wall guide plate is arranged along an opening and closing travelling line on the free end of the gate-type curtain wall, and is connected with the first sliding surface of the free end frame. The device solves joint processing of the facade of a seismic isolation gap of a seismic isolation building, and the device is beautiful and elegant, and ensures integrity and consistency of the facade, and function usage of the building at ordinary times is not influenced.

Description

technical field [0001] The invention belongs to the field of building protection, in particular to a facade shock-isolating device used at deformation joints of shock-isolated buildings and a construction method thereof. Background technique [0002] In recent years, earthquakes have occurred frequently in my country, and the application of building isolation technology has become more and more extensive. Building seismic isolation is no longer limited to small buildings. A large number of super-long and super-large buildings also need to be designed for seismic isolation. Such buildings often need to be separated by seismic isolation joints. Due to the adoption of seismic isolation technology, the horizontal displacement of the upper structure of the building is relatively large, and the horizontal displacement is two-way displacement. Therefore, a new structural measure is needed to ensure the continuation of the facades on both sides of the seismic isolation joint and the...
