Problems solved by technology
[0003] During the installation and use of concrete building panels in winter, due to the large temperature difference between day and night, at night, the connecting device will freeze after being wet, and will not melt until the daytime. This process lasts for a long time, so it will make the connecting device easy to Corrosion, which affects the use of the connection device

The invention discloses a prefabricated concrete building panel installation and connection device, which relates to the technical field of construction sites. The precast concrete building panel installation connection device includes a building panel connection mechanism for building panel connection, a thermal expansion and contraction mechanism for thermal expansion and contraction, an elastic shaking mechanism for shaking based on elasticity, and a fan-shaped drum. A leaf bulging mechanism for crushing the ice surface is provided, and a connecting plate is arranged inside the building board connecting mechanism. The connection device installed on the prefabricated concrete building slab can offset the expansion coefficient of the concrete slab to a certain extent through the thermal expansion of the mercury in the mercury tank when the temperature is high during the day, so that the bulging slab will squeeze the concrete slab. The top of the second airbag bulges after being squeezed by the first airbag, and the bulging angles of the four second airbags are different, so that the first coil spring shakes at different angles, so that the hitting ball hits the connecting plate.
Description
technical field [0001] The invention relates to the technical field of construction sites, in particular to a prefabricated concrete building board installation and connection device. Background technique [0002] Concrete pouring refers to the process of pouring concrete into the mold until it is plasticized. In civil construction engineering, putting concrete and other materials into the mold to make a predetermined shape is the most basic and very important step in civil construction; concrete building panels are A pre-poured building board. [0003] During the installation and use of concrete building panels in winter, due to the large temperature difference between day and night, the connecting device will freeze after being wet at night, and will not melt until the daytime. This process lasts for a long time, so it will make the connecting device easy to Corrosion, which affects the use of the connection device. Contents of the invention [0004] Aiming at the defi...
