Large wall template support system

The utility model relates to a large wall template support system. The large wall template support system comprises two oppositely arranged wall surface support plates, wherein a plurality of vertical pressure rods are arranged on the outer side faces of the two wall surface support plates respectively; a plurality of groups of corresponding first transverse pressure rods are arranged on the outside of the two wall surface support plates respectively, and are parallel to the wall surface support plates; the vertical pressure rods are positioned between the first transverse pressure rods and the wall surface support plates; the first transverse pressure rods are in contact with the vertical pressure rods; the first transverse pressure rods corresponding to the outside of the two wall surface support plates are connected through a plurality of fasteners. Through the adoption of the scheme, a wall template support structure can be quickly built by making full use of existing materials, wall surface support plates can be disassembled and assembled without re-customized production, large-area support can be realized, and the large wall template support system is also convenient to store and transport, so that the wall surface support plates are stably and firmly fixed.
