Problems solved by technology

[0008] However, there are certain defects in the construction methods of the above-mentioned several floor slabs.
First of all, certain cast-in-place operations are required, and the assembly rate is low. At the same time, the assembly process is more complicated and the construction is more difficult; second, the overall steel consumption is large and the cost is high
[0009] However, since the production process of autoclaved aerated concrete slabs involves a series of processing steps such as cutting and curing, it is difficult to embed steel trusses with complex structures into the slabs in advance. The performance improvement is relatively limited, and it is difficult to meet the needs of the floor

preparation example Construction

[0052] The core of the preparation method of the present invention lies in step S1 and step S3. First, configure the corresponding steel bar trusses 2 according to the corresponding building type. Then, according to the setting of the cutting equipment used in the cutting link of the subsequent production, the steel bar trusses 2 are stacked and arranged in the concrete mold at intervals. When stacked, the steel bar truss 2 can be fixed and positioned by inserting brazing. Specifically, a drill hole can be provided on the mold, and then the fixing drill is inserted into the mold through the drill hole, and the steel bar truss 2 can be accurately fixed in the mold through the fixing drill. After the mud is poured in, it is only necessary to take out the fixing braze to complete the implantation of the steel bar truss 2 . This production method can effectively realize the accurate implantation of the steel bar truss 2 with a complex structure into the lightweight concrete slab...

Abstract

The invention discloses a manufacturing method of an autoclaved aerated concrete floor slab. The manufacturing method comprises the following steps that S1, steel bar trusses are prepared; S2, the rawmaterials of the autoclaved aerated concrete floor slab are fed according to the raw material ratio to prepare concrete mixed pug; S3, the mixed pug prepared in the step S2 is poured into a concretemold, meanwhile, the steel bar trusses prepared in the step S1 are fixedly arranged in the concrete pug in a spaced stacking mode, compaction and forming are conducted, and an autoclaved aerated concrete rough blank is prepared; S4, the autoclaved aerated concrete rough blank prepared in the step S3 is cut according to the floor slab size requirement, and a floor slab rough blank is prepared; andS5, the floor slab rough blank prepared in the step S4 is subjected to subsequent autoclaved aerated treatment, and the autoclaved aerated concrete floor slab is prepared. According to the manufacturing method, on the premise that the bearing performance is met, complete overall prefabrication of the floor slab is achieved, and the manufactured floor slab is light in weight, high in strength and easy to assemble.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a method for manufacturing an autoclaved aerated concrete floor. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and transported to the construction site. Reliable connections are assembled and installed on site. Compared with traditional buildings, prefabricated buildings have the advantages of less on-site cast-in-place operations, a higher degree of standardization, shorter construction periods, more in line with the requirements of green buildings, and more energy-saving and environmentally friendly. In recent years, my country has attached great importance to the development of the prefabricated co...
