Brick concrete smearing device for building construction

The utility model discloses a brick concrete smearing device for building construction, belongs to the technical field of building construction, and is used for solving the problems that time and labor are wasted and efficiency is low when concrete is smeared on the surfaces of bricks manually. Comprising a storage box, a lifting mechanism is arranged on the right side of the storage box, the lifting mechanism comprises a mounting plate, a limiting mechanism is arranged in the mounting plate, and the limiting mechanism comprises a second threaded rod and a third threaded rod; by arranging the limiting mechanism, a relatively closed space can be formed on the upper surfaces of the bricks, so that concrete can be smeared in the space, concrete smearing work on the surfaces of the bricks is completed, and the same amount of concrete can be stably smeared on the surfaces of a whole row of bricks due to the fixed arrangement of the space; and the situation that the use effect is affected due to non-uniform concret
