Concrete grid-shaped framework wall

The invention relates to a building wall body taking concrete as a framework, wherein the framework is in a grid shape in a wall. The preparation method comprises the following steps that a specially-made sandwich brick is placed in the middle of two facing bricks so as to form a whole building block, and the whole building block is taken as a pouring mold cavity; grooves are formed in the periphery of the mold cavity, wherein runners are arranged inside the mold cavity. Similar to a conventional wall building method, according to the concrete grid-shaped framework wall, building blocks are arranged one by one and stacked layer by layer, and concrete mortar is poured into the grooves and runners while building block laying is undergoing; after the concrete is coagulated to become the grid-shaped framework, and the grid-shaped framework and the mold cavity form the complete wall body; and in addition, a water-electricity pipeline can be arranged in the middle of the building block grooves. 一种以混凝土为骨架的建筑墙体，骨架在墙内
