Description

Technical Field

[0001] The present invention belongs to the technical field of concrete blocks, and in particular relates to a masonry-free lightweight self-insulating assembled concrete single-piece wall and a multi-piece wall. Background Art

[0002] Masonry structures are widely used in civil buildings, commercial buildings, public buildings, public facilities and other construction projects due to their low cost and the advantages of using local materials. However, traditional masonry structures still have many disadvantages: construction quality depends on labor, wastes materials and pollutes the environment, construction efficiency is low, construction is easily affected by climate, construction quality is difficult to guarantee, and seismic performance is poor.

[0003] Prefabricated masonry refers to the construction process of masonry structures that are prefabricated in factories and assembled on site. Compared with traditional on-site masonry, this method has the advantages of fast construction speed, good quality control, labor saving, and reduced on-site construction risks.

[0004] However, prefabricated masonry structures are prefabricated as a whole wall in the factory and have a large self-weight. They are extremely inconvenient to transport to remote mountainous areas, islands and other areas. Formwork is required during the assembly process at the construction site, which increases the construction time. At the same time, prefabricated masonry structures are heavy and can only be lifted with large equipment. Small lifting equipment cannot meet the lifting and transportation requirements. Summary of the invention

[0005] In order to solve the above problems existing in the prior art, the present invention provides a masonry-free lightweight self-insulating assembled concrete single-piece wall and multi-piece wall. The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0006] A first aspect of the present invention provides a masonry-free lightweight self-insulating assembled concrete monolithic wall, comprising:

[0007] The block structure layer is formed by stacking a plurality of first block layers and a plurality of second block layers alternately and staggered in a vertical direction; the adjacent first block layers and the second block layers are matched with mortise and tenon joints;

[0008] The steel bar system comprises: transverse limiting steel bars, vertical distribution steel bars, vertical steel bar cages, and transverse steel bar cages, wherein the transverse limiting steel bars are arranged at the connection between each first block layer and the second block layer in the horizontal direction; the vertical distribution steel bars are arranged in the vertical direction through the interior of the block structure layer; the vertical steel bar cages are arranged in the vertical direction through the two ends of the block structure layer in the horizontal direction; and the transverse steel bar cages are arranged in the horizontal direction through the top of the block structure layer.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present invention provides a masonry-free lightweight self-insulating assembled concrete monolithic wall, i.e., a multi-piece wall. The first block layer and the second block layer are connected by mortise and tenon joints, and the integrity of the wall is improved by a steel bar system, so that assembly is first performed and then grouting is performed to form a complete formwork-free reinforced masonry structure. The smallest unit of the wall provided by the present invention is a block, which has a small volume, a light weight, and is convenient to transport. It can solve the problem of transporting self-built houses in remote mountainous areas, islands, and other areas with inconvenient transportation, making the blocks more convenient and economical during transportation, and the connection method between the blocks is more optimized. Formwork-free construction is possible at the construction site, and the advantages of fast construction speed and convenience are achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The embodiment provides a masonry-free lightweight self-insulating assembled concrete monolithic wall and multi-piece wall, which are connected by a mortise and tenon connection structure, and the convex-convex matching of the convex part and the concave-convex part can form a mortise and tenon connection between vertically adjacent blocks, and can also make the horizontally adjacent blocks bite each other to provide friction, thereby realizing a mortar-free block connection, increasing the firmness of the block wall while simplifying the construction steps, and thus improving the seismic bearing capacity of the wall. In addition, the transverse limiting steel bars 410, the vertical distribution steel bars 420, the vertical steel cage 430, and the transverse steel cage 440 can improve the integrity of the wall, and can realize assembly first and then grouting to form a complete formwork-free reinforced masonry structure. The smallest unit of the wall provided in the embodiment is a block, which has a small volume, a light weight, and is convenient to transport. It can solve the problem of transporting self-built houses in remote mountainous areas, islands and other inconvenient areas, making the blocks more convenient and economical during transportation, and the connection method between the blocks is more optimized. Formwork can be avoided at the construction site, which has the advantages of fast construction speed and convenience.
