[0026] The earthquake-resistant, blast-resistant and crack-resistant composite wall is used for partition walls in buildings, and is particularly suitable for the construction of walls with a height of more than 3 meters. It includes two parallel walls 6, a steel frame 1, steel string reinforcements 2 installed in the steel frame 1, and a keel 3 bonded to the steel string reinforcements 2 and located between the two walls 6. The wall 6 is bonded to the keel 3, and concrete cement or foamed concrete or concrete with perlite added is poured between the wall 6. The keel 3 is perpendicular to the wall 6 and is vertically arranged. The steel frame and steel string reinforcement enhance the overall earthquake-resistant, crack-resistant and blast-resistant effects of the composite wall. The keel mainly plays a reinforcing role and further enhances the earthquake-resistant, crack-resistant and blast-resistant effects.

[0027] The steel structure replaces the traditional structural columns and ring beams, and the installation position is wider. Reasonable construction of the steel structure frame is helpful to improve the earthquake resistance, crack resistance and explosion resistance of the composite wall. The steel structure frame includes a vertical steel structure frame 11 and a horizontal steel structure frame 12 fixedly connected together. The vertical steel structure frame 11 is fixedly installed between the upper top surface 5 and the lower bottom surface 7 in the building space and / or between the horizontal steel structure frame 12 and the lower bottom surface 7 in the building space. The number of vertical steel structure frames 11 between the horizontal steel structure frame 12 and the lower bottom surface 7 in the building space is greater than the number of vertical steel structure frames 11 between the upper top surface 5 and the lower bottom surface 7 in the building space. Steel chord reinforcement 2 is also separately fixed between the horizontal steel structure frame 12 and the upper top surface 5 in the building space.

[0028] The keel is bonded to the steel string stud 2 by a flame retardant adhesive, and the wall surface 6 is bonded to the keel 3 by a flame retardant adhesive. Since the materials used in the combined wall are all flame retardant and anti-permeability, the combined wall as a whole has flame retardancy and anti-permeability, meeting the fire prevention and anti-permeability requirements.

[0029] Preferably, the steel chord reinforcement 2 is a vertical steel chord reinforcement, which passes through the horizontal steel frame 12 and is fixedly connected to the upper top surface 5 and the lower bottom surface 7 in the building space by expansion hooks and basket bolts. Furthermore, the steel chord reinforcement 2 also includes horizontal steel chord reinforcements perpendicular to the vertical steel chord reinforcements. The spacing between two adjacent steel chord reinforcements is 30-40 cm.

[0030] Preferably, each keel 3 is bonded to the steel string reinforcement 2 by at least two bonding blocks 4, preferably three. The material of the keel 3 is consistent with the material of the wall surface 6.

[0031] A layer of steel wire mesh is built into the wall 6, and a layer of alkali-resistant glass fiber mesh is arranged on both sides of the steel wire mesh, and the steel wire mesh and the alkali-resistant glass fiber mesh are parallel to the wall 6. The earthquake-resistant, crack-resistant and explosion-resistant effects are further enhanced.

[0032] Preferably, the joints of the spliced ​​panels of the wall surface 6 are provided with caulking mesh cloth, which improves the crack resistance of the wall surface joints.

[0033] Preferably, the outer surface of the wall 6 is entirely covered with a steel mesh fixed thereon to prevent the wall from bulging due to the lateral pressure of the filling material when the filling material is poured.

[0034] During construction, first fix the steel frame 1 in the building space, fix the steel string reinforcement on the steel frame 1 or in the building space, glue the keel 3 to the steel string reinforcement 2, glue the wall to the keel 3, and install the keel and the wall by climbing each other, and the installation of the combined wall is completed.

[0035] Embodiment 2: The earthquake-resistant, blast-resistant, and crack-resistant composite wall is used for the exterior wall of a building. On the basis of Embodiment 1, a wall surface with decorative or thermal insulation functions can be selected. Its earthquake-resistant, crack-resistant, blast-resistant, thermal insulation, and decorative properties meet the requirements of exterior wall construction.
