Description

Technical Field

[0002] In areas of high seismic intensity, earthquakes are extremely destructive to buildings, which often face various types of damage caused by earthquakes, among which roof leakage is a common problem. The design of seismic isolation joints is one of the important means to reduce the extent of earthquake damage. However, the existing seismic isolation joint designs often have shortcomings in waterproofing, especially after the deformation and displacement caused by earthquakes, the waterproof structure is prone to failure. In addition, the existence of seismic isolation joints makes buildings face challenges in terms of thermal insulation, because these gaps can easily become channels for heat loss. Especially in cold areas, the quality of thermal insulation performance is directly related to the energy consumption and user comfort of the building. However, traditional seismic isolation joint waterproofing and insulation designs have limitations in adapting to the displacement and deformation caused by earthquakes, and cannot meet the special needs of buildings in areas of high seismic intensity.

[0003] Therefore, how to provide a composite waterproof and thermal insulation system for roof isolation joints in high seismic intensity areas that can ensure that the roof's waterproof performance remains reliable under extreme conditions such as earthquakes, and can significantly improve the building's thermal insulation performance and reduce energy waste is an urgent problem that technical personnel in this field need to solve. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a roof isolation joint composite waterproof and thermal insulation system for high seismic intensity areas. The opposite sides of the roof structure 1 and the roof structure 2 are both provided with upwardly extending walls, and the isolation joint is located between the two walls. The system comprises:

[0007] A first waterproofing membrane is integrally extended and laid on the upper surfaces of the first roof structure and the second roof structure to form a seamless waterproof barrier covering the seismic isolation joint; the first waterproofing membrane has a loose laying section corresponding to the seismic isolation joint so as to relax and expand with the deformation of the seismic isolation joint;

[0008] An anti-vibration telescopic frame body is installed at the upper ends of the two walls to adaptively expand and contract when the seismic isolation joint is deformed;

[0013] The utility model is a composite waterproof and thermal insulation system for roof isolation joints in high seismic intensity areas. The waterproof cover plate is used as the first waterproof layer to ensure good flatness and directly prevent the impact and penetration of rainwater.

The waterproof membrane 1 integrally extended and laid on the upper surface of the roof structure 1 and the roof structure 2 serves as the third waterproof layer to form a seamless waterproof barrier, further ensuring the waterproof effect of the entire roof. By setting up a three-layer waterproof structure, multiple waterproof barriers are formed, which can effectively prevent water penetration and ensure the waterproof safety of the roof. The isolation joints are filled with flexible thermal insulation materials that can adapt to the deformation of the isolation joints to ensure the connectivity of the thermal insulation between the roofs, reduce heat loss, and improve the thermal insulation performance of the building. The isolation nodes are designed with a seismic telescopic frame to adapt to the displacement changes between the two relative roofs, maintaining the stability and safety of the roof.

[0025] As a further improvement of the above technical solution, a wave-shaped elastic expansion plate is installed between the two walls corresponding to the lower end of the flexible thermal insulation material, which supports the flexible thermal insulation material and can expand and contract with the deformation of the seismic isolation joint.

[0026] The beneficial effects of the above technical solution are: the wavy elastic expansion plate supports the flexible thermal insulation material, thereby improving the stability of the installation of the flexible thermal insulation material, and the wavy elastic expansion plate can be bent and expanded, thereby achieving adaptability to changes in the width of the seismic isolation joint.

[0027] As a further improvement of the above technical solution, the waterproof cover plate is a fluorocarbon sprayed aluminum single plate.
