Abstract
The invention discloses a hit-preventing wall template which comprises an outer mould and an inner mould matched with the outer mould. The inner mould and the outer mould are fixed through a split screw, a bent plate and an upper top plate are connected with the bottom of the outer mould in sequence, and the bent plate and the upper top plate are in a hook shape. When the split screw transmits tensioning force to the outer mould, the outer mould forms a rotating shaft. The center of the rotating shaft is a contact point of the upper top plate and the bottom of a bridge, and pulling force of the split screw enables the outer mould to form rotation torque with the contact point as the center. Therefore, the position of the outer mould can be fixed, acting force between the bottom of the outer mould and the bridge is enhanced, and the problem that mould explosion caused by vibration of concrete in the concrete pouring process and other problems are avoided. Compared with a traditional mode that a scaffold fixes an inner mould and the outer mould, through a change of the structure of the outer mould, the scaffold is eliminated, erecting time and erecting cost of the scaffold are reduced, and building cost is greatly lowered.
