As preferred scheme, the size of through-hole with the grout hole is the same, the utility model discloses a building block polylith splices the back, because the existence of through-hole in the arch, can form a grout hole naturally between lug and recess, the size of through-hole is the same with the grout hole size between two holes, changes the control grout volume, improves the stability of structure to after the building block piles up with "article" style of calligraphy mode, the grout hole is straight to the through-hole, also makes things convenient for the operator directly to be in milk, strengthens the building performance, uses conventional method of piling up also very stable.

The technical scheme has the following beneficial technical effects:

the assembled masonry technology can solve the current situations that the precast concrete system is high in price and single in building shape, and is easy to accept by users. The prefabricated building with the prefabricated block materials built into the wall body is suitable for building 3-5 storied buildings by using an assembled masonry technology, and the number of layers can be properly increased if the strength of building blocks is improved or reinforcing steel bars are configured. Can also be used for manufacturing the filler wall. The building block has strong building adaptability, simple production process, simple and convenient construction and lower manufacturing cost, and can also utilize local materials and industrial waste materials. The building blocks are small, medium and large, wherein the small blocks are suitable for manual carrying and building, and have the advantages of low industrialization degree, flexibility, convenience and wide application range.

The utility model discloses use hollow block as the design basis, improve, refer to the design of chain hollow block piece type, design into unsmooth form with two sides of hollow block for it is inseparabler to connect between the building block, and additionally designs the grout hole, uses a small amount of cement mortar to consolidate and connects the preferred embodiment of the utility model discloses an in, the shrinkage pool adopts the form in trapezoidal hole, can make the arch change enter into the shrinkage pool, strengthened the agreeable nature of building block. Of course, concrete can be poured into the vertical holes at the two ends of the block wall body to lay reinforcing steel bars, so that a reinforced concrete core column is formed, the capability of resisting longitudinal displacement is effectively improved, a better effect is obtained, and the integrity of the masonry is improved. The designed building blocks are not only limited to on-site building, but also can be built into a wall body by using the assembly type hollow building blocks in a prefabrication plant, and the built wall body is assembled with a building, so that compared with the existing assembly type building blocks, the on-site building method has the advantages that the construction efficiency is higher, and the on-site construction time is saved.
