Description

TECHNICAL FIELD

[0001] The utility model relates to concrete precast member technical field, concretely is a kind of concrete precast member splicing joint self-closing sealing structure. BACKGROUND

[0002] With the acceleration of urbanization, the scale and quantity of construction projects are increasing, and the requirement for construction efficiency is also increasing. The traditional site pouring construction method needs a large number of formwork erection, concrete pouring and maintenance time, and the construction period is long and the efficiency is low. The concrete precast member is prefabricated in the factory, then transported to the construction site for installation, which can greatly reduce the site construction time and improve the overall construction efficiency.

[0003] When assembling the concrete precast member, since there is a gap at the splicing part of the concrete precast member, the splicing part is usually filled with sealant. When the sealant solidifies, the splicing part can be filled up, which can ensure that the precast members can be connected more tightly, reduce the probability of gap occurrence, effectively prevent the intrusion of external substances, and thus improve the durability and waterproof performance of the concrete precast member.

[0004] However, due to the influence of external vibration after long-term use of the concrete precast member, relative displacement may occur between the concrete precast members, which may cause the sealant to fall off from the precast member, resulting in a gap at the splicing part. This phenomenon not only causes water and impurities to invade the interior of the concrete precast member, causing water seepage in the concrete, but also may affect the service life of the concrete precast member.
