[0002] As a new type of building material, autoclaved aerated concrete blocks have excellent performance compared to traditional clay bricks. However, in the existing wall construction using ordinary autoclaved aerated concrete blocks, for example, patent No. CN200920200669.X discloses an autoclaved aerated concrete block masonry infill wall, which includes a first infill wall composed of multiple layers of autoclaved aerated concrete blocks stacked horizontally and with staggered vertical joints, and a second infill wall composed of solid bricks that are sequentially mortared obliquely on the right inclined surface of the prefabricated parts, wherein the top corners of the solid bricks are against the top beam, and the bottom corners of the solid bricks are against the top of the first infill wall, and the gaps are filled with mortar. The beam-column structure made of concrete materials needs to be cast on site, and a large amount of cement mortar needs to be filled between the autoclaved aerated concrete blocks to fix them, which makes the construction work cumbersome and inefficient. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to propose an autoclaved aerated concrete block, a masonry wall and a construction method thereof, so as to solve the problem that the beam-column structure of the wall concrete material needs to be cast on site, and a large amount of cement mortar needs to be filled between the autoclaved aerated concrete blocks for fixation, which makes the construction operation cumbersome and inefficient.

[0004] Based on the above purpose, the present invention provides an autoclaved aerated concrete block, comprising a block body;

[0005] The top of the block body is provided with a block inner hole in the vertical direction;

[0006] It also includes a prefabricated connecting piece, the top end of which is assembled and connected to the concrete structure of the wall, and the bottom end of the prefabricated connecting piece is used to penetrate into the inner hole of the block for connection.

[0007] Preferably, the prefabricated connecting member is made of steel structure.

[0008] Preferably, the prefabricated connecting member includes a bolt head and a bolt shank fixed to the bottom end of the bolt head, and the inner ring of the inner hole of the block is provided with an internal thread matching the bolt shank.

[0009] The present invention also provides a masonry wall, which is constructed by combining the above-mentioned autoclaved aerated concrete blocks and ordinary autoclaved aerated concrete blocks;

[0010] The foundation wall is formed by laying ordinary autoclaved aerated concrete blocks, and a precast concrete crossbeam is provided at the top of the door and window openings of the foundation wall. Precast concrete side columns are provided at the side ends of the door and window openings of the foundation wall. A first assembly hole is provided at the top of the precast concrete crossbeam, and a column inner hole is provided at the top of the precast concrete side column, so that precast connecting parts can be inserted into the first assembly hole and the column inner hole in sequence for connection.

[0011] Concrete steps are arranged vertically at intervals on the side of the precast concrete side column facing the foundation wall. A second assembly hole is opened at the top of the concrete steps. The block bodies are inserted between the concrete steps so that the precast connecting parts can be inserted into the second assembly holes and connected in the inner holes of the blocks in sequence. The block bodies are built with ordinary autoclaved aerated concrete blocks on the outside of the concrete steps.

[0012] Preferably, the concrete steps and the precast concrete side columns are integrally cast and prefabricated.

[0013] Preferably, the diameter of the bolt head is larger than the diameter of the bolt shank.

[0014] Preferably, an outer end of the bolt head is provided with an external thread, and the inner circles of the first assembly hole and the second assembly hole are both provided with an internal thread matching the bolt head.

[0015] The present invention also provides a construction method for building a wall, comprising the following steps:

[0016] a: Prefabricate precast concrete beams and precast concrete side columns;

[0017] b: Transport the prefabricated precast concrete beams and precast concrete side columns to the site, and lay the precast concrete beams horizontally to the top of the precast concrete side columns on both sides, with the concrete step side facing outwards;

[0018] c: Insert the prefabricated connecting parts along the first assembly hole and the inner hole of the column in sequence;

[0019] d: Starting from the bottom concrete step, insert the block body into the gap at the bottom of the concrete step, and insert the prefabricated connecting parts along the second assembly hole and the inner hole of the block in sequence, filling the gap between the concrete steps from bottom to top;

[0020] e: On the outside of the concrete steps, use ordinary autoclaved aerated concrete blocks and the block bodies to build a wall.

[0021] Preferably, both ends of the precast concrete beam extend beyond the precast concrete side column by a certain distance, and a third assembly hole is provided on both ends of the precast concrete beam extending beyond the precast concrete side column. In step d, the precast connecting piece is finally inserted into the inner hole of the block of the topmost block body along the third assembly hole.

[0022] The beneficial effects of the present invention are as follows: by using the above-mentioned autoclaved aerated concrete blocks and ordinary autoclaved aerated concrete blocks to build a wall together, wherein ordinary autoclaved aerated concrete blocks are used to build a foundation wall, and the original lintels and side columns at the door and window openings of the foundation wall are prefabricated with precast concrete cross beams and precast concrete side columns respectively. In particular, concrete steps are arranged at intervals along the vertical direction on the side of the precast concrete side columns facing the foundation wall, and the block bodies are inserted into the intervals between the concrete steps, and the block bodies are built with the ordinary autoclaved aerated concrete blocks on the outside of the concrete steps, thereby improving the wall structure compared to the traditional wall structure. The lintels and side columns are directly built with ordinary autoclaved aerated concrete blocks in the form of step insertion. The prefabricated connectors at the steps are sequentially inserted into the second assembly holes and the inner holes of the blocks for connection and fixation. The structure is more stable and does not require excessive cement mortar for bonding and fixation. At the same time, the prefabricated connectors are used to be inserted into the first assembly holes and the inner holes of the columns to fix the precast concrete beams and precast concrete side columns. There is no need for on-site casting and production. The construction operation is simple and efficient, and the problem of shrinkage cracks easily occurring at the junction of traditional autoclaved aerated concrete blocks and wall concrete structures that are directly bonded with a large amount of mortar is avoided.
