Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of deformation joint connection of civil structure plate, in particular to a deformation joint connection device for civil structure plate and a use method thereof. BACKGROUND

[0002] With the acceleration of urbanization, concrete slab structures are widely used in large-span buildings and structures such as basements, parking lots, and bridges. Due to the influence of temperature changes, foundation settlement, external loads, and other factors during the use of concrete slabs, deformation joints are often set between concrete slabs to absorb stress caused by thermal expansion and contraction, displacement deformation, and other reasons, thereby preventing structural cracking and damage. The use of such deformation joints in building structures has become a key factor in ensuring structural stability and extending the service life of buildings.

[0003] Metal plates, rubber belts, and other materials are commonly used to connect at the deformation joint to solve the displacement problem between concrete slabs. For example, some structures use rigid connections to directly connect the two sides of the concrete slab with rigid materials, thereby avoiding displacement deformation. However, such designs often fail to effectively absorb deformation stress caused by temperature or foundation settlement, which can lead to cracking of concrete slabs over time, and even structural instability in severe cases. To solve this problem, some designs introduce elastic materials such as rubber belts at the deformation joint to provide flexible connections, but existing designs often lack effective support and waterproof protection, which can easily fail over time.

[0004] Due to the lack of adequate flexible connection design, the connection device at the deformation joint cannot effectively absorb and relieve the displacement of the concrete slab caused by factors such as temperature changes or foundation settlement, thereby easily causing cracking of the concrete slab or structural instability. At the same time, the existing sealing structure is relatively simple and lacks adequate waterproof performance, especially in underground or humid environments, which can easily allow water to penetrate, thereby corroding the internal structure and further affecting the durability and safety of the device. Therefore, there is an urgent need for a deformation joint connection device that can provide flexible connections, good support, and waterproof performance to solve the above problems in the prior art.
