Description

Quick net-hanging device for planting bar on concrete base surface Technical Field The utility model relates to the technical field of net hanging devices, in particular to a rapid net hanging device for planting ribs on a concrete base surface. Background In the field of constructional engineering, a concrete structure is used as a widely applied building form, the stability and the durability of the concrete structure are directly related to the safety and the service life of a building, and a concrete base surface can be influenced by various factors such as environmental erosion, load action and the like in the long-term use process, so that the structural performance of the concrete base surface is reduced, the reinforcement treatment of the concrete base surface is necessary, and a reinforcement method of bar planting and net hanging is a relatively common reinforcement mode, and the bearing capacity and the crack resistance of the concrete base surface are enhanced by implanting steel bars on the concrete base surface and hanging steel wire nets. After the existing hanging net is fixed, as the material characteristics of the steel wire net and the concrete base surface are different when the environmental temperature changes, the degree of thermal expansion and cold contraction is different, and thus local stress concentration occurs between the steel wire net and the concrete base surface. The stress concentration can lead to the bulge phenomenon of the wall surface at first, and the bulge situation can become more serious with the continuous lapse of time, and finally the wall surface is dropped. The method not only seriously threatens the safety of the building structure, but also greatly increases the cost of later maintenance and rectification, and brings great trouble to the maintenance and management of the building. Therefore, the utility model provides a rapid net hanging device for planting bars on a concrete base surface. Disclosure of utility model The utility model aims at solving the problems that in the background technology, when the environmental temperature changes, the material characteristics of a steel wire mesh and a concrete base surface are different, and the degree of thermal expansion and cold contraction is different, so that local stress concentration occurs between the steel wire mesh and the concrete base surface. The stress concentration can lead to the bulge phenomenon of the wall surface at first, and the bulge situation can become more serious with the continuous lapse of time, and finally the wall surface is dropped. The safety of the building structure is seriously threatened, the cost of later maintenance and rectification is greatly increased, the problem of great trouble is brought to maintenance and management of the building, and the rapid net hanging device for the bar planting on the concrete base surface is provided. The quick net hanging device for the embedded steel bars on the concrete base surface comprises a plurality of embedded steel bars embedded in the concrete base surface, a galvanized steel wire net used for reinforcing the concrete base surface is hung on the embedded steel bars, a limiting component used for limiting and fixing the galvanized steel wire net is arranged on the embedded steel bars, the limiting component comprises a first limiting plate and a second limiting plate, the first limiting plate and the second limiting plate are arranged in a crossed mode, limiting bolts penetrate through threads at the crossed positions of the first limiting plate and the second limiting plate, guide grooves are formed in two ends of the first limiting plate and the second limiting plate respectively, a sliding block is arranged in the guide grooves in a sliding mode, one end of each sliding block is fixedly connected with a connecting sleeve block, the other end of each sliding block is fixedly connected with a spring, one end of each spring is fixedly connected with the inner wall of each guide groove, a high-strength wear-resisting layer is paved on the outer wall of each embedded steel bar, and concrete layers are paved on the outer sides of the high-strength wear-resisting layers.
