Description
Technical Field
The utility model relates to the technical field of building structure earthquake resistance, in particular to a telescopic elevation enclosure device for a building earthquake isolation joint and an enclosure structure.
Background
Earthquake damage indicates that the main cause of casualties and economic losses caused by earthquakes is collapse and destruction of building construction. The adoption of the shock insulation technology is one of the most effective technologies for enhancing the shock resistance of the building structure and relieving the earthquake disasters at present. In the building adopting the earthquake isolation technology, the reserved space of the earthquake isolation joint is used for ensuring the normal function of the earthquake isolation building in the earthquake. However, the earthquake damage results show that building enclosure or protection measures on two sides of the earthquake isolation joint in the earthquake isolation building, especially in the earthquake isolation building in a medium and high intensity area, have the problem of influencing normal exertion of the earthquake resistance of the earthquake isolation structure.
Firstly, the lateral bearing capacity of building envelope or protective measures crossing the side surface of the channel is insufficient due to the large width of the shock insulation seam. The reason is that no special matched drawing set for building maintenance on the side face of the channel crossing the shock insulation joint is available for the designer to choose, and the drawing set can only be used according to the existing building deformation joint drawing set. The maximum seam width applicable to the building deformation joint chart set is only 300mm, and the seam width of the shock insulation joint in the shock insulation building in the medium and high intensity area even reaches 800mm or more, and the shock insulation joint chart set is still used according to the building deformation joint chart set or is self-reformed during design, so that the problem of insufficient lateral bearing capacity of the shock insulation joint side building due to the enlarged span is caused.
And secondly, building maintenance or protective measures on two sides of the shock insulation seam channel cause that the shock insulation seam is blocked and can not be freely shifted due to self damage or damage and damage of other components in an earthquake, and further the shock insulation structure can not be normally deformed, so that damage and damage to an upper structure are caused.
