For the bottommost building block, all hole parts (the hole 6, the end groove 5 and the grouting hole 4) of the building block are filled with C20 concrete, and the filling depth is not less than 10 cm. The middle building blocks of the wall body are piled with 3-4 layers each time and are grouted, the uppermost building block is not filled, and preferably, the middle of the uppermost building block is grouted. A layer of building blocks (the layer below the beam) is arranged on the uppermost part of the wall body, and holes are formed in the corresponding grouting positions for grouting.
In summary, according to the vertical hole grouting type building block and the construction process thereof disclosed by the invention, the end part grooves 5 are arranged at the end parts of the building blocks, the holes 6 are reserved in the middle parts, after the building blocks are stacked, the end part grooves 5 of the adjacent building blocks are filled with bonding mortar or concrete to form mortar or concrete (bonding) core columns, and the building blocks are connected left and right and are stringed up and down through the core columns. Furthermore, a grouting hole 4 is arranged in the middle for pouring bonding mortar or concrete.
The invention is mainly used for the hollow building block, and because the bonding area of the traditional bonding process is small when the hollow building block is built, the integrity, the stability and the shock resistance of the building body are low. The invention designs the building blocks with holes which are penetrated up and down, column cavities formed by end grooves 5 of adjacent building blocks and/or grouting holes 4; the building blocks are stringed by pouring bonding materials such as mortar or concrete into the column cavity and the grouting holes 4, so that the stability and the integrity of the masonry (block) body can be greatly improved, the anti-seismic performance of the masonry (block) body is improved, the structure and the process abandon the bonding mortar joint of the traditional process, and after the stringing process for the building blocks is completed, the wall surface is smooth, painting is not needed, the masonry speed is high, and the traditional masonry is changed into simple stacking. The connection mode of vertical hole grouting saves manpower, brick building materials and painting materials, improves efficiency, saves manufacturing cost, prevents the wall from hollowing and cracking, and greatly improves the stability, integrity and shock resistance of the wall.
