Autoclaved sand aerated concrete block wall construction method based on BIM technique

Abstract

The invention relates to an autoclaved sand aerated concrete block wall construction method based on the BIM technique. The method comprises the steps of acquiring data information required by wall construction according to a two-dimensional wall CAD building structural working drawing; conducting three-dimensional modeling on a wall by means of BIM molding software, inputting the data information into the three-dimensional model of the wall, and making autoclaved sand aerated concrete blocks serve as building blocks in the three-dimensional model of the wall; arranging the building blocks in the three-dimensional model of the wall, and conducting coding on the building blocks in different specifications; acquiring data information including the specifications and number of the building blocks, mortar joint thickness and door and window openings required by wall construction from the three-dimensional model of the wall; extracting and making a plan for various materials and a machining material list; purchasing the building blocks and having the building blocks in place; conducting building block processing; conducting wall construction. According to the method, wall building block arrangement is conducted by means of the BIM technique, building block arrangement precision and speed are high, building block consumption is reduced, and wall construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of an autoclaved sand aerated concrete block wall based on BIM technology. Background technique [0002] BIM technology (Building Information Modeling) is usually translated as Building Information Modeling. As a new concept in the engineering construction industry, BIM technology emphasizes the application of coordinated information in all stages of the project life cycle, and its most intuitive form of expression is the 3D building model with project information. The 3D building information model is no longer an immutable exhibit, but an intelligent information carrier, and with the enrichment and transmission of information, the model will become the core and data basis for specific applications in each stage of the project's life cycle. [0003] With the gradual promotion of BIM technology in construction projects, more and more design uni...

Problems solved by technology

[0004] The present invention mainly solves the problem that in the construction process of the original autoclaved sand aerated concrete block wall, the master mason with rich construction experience mainly arranges the bricks manually and cuts the blocks on site according to the experience. The manual brick arrangement is not only low in work efficiency, but also Increase the cutting loss of blocks, resulting in a large amount of masonry waste, and there may be errors in brick arrangement, resulting in rework, delays in construction period, and technical problems in increasing construction costs; provide an autoclaved sand aerated concrete based on BIM technology The block wall construction method uses BIM technology to carry out three-dimensional modeling of the autoclaved sand aerated concrete block wall, and determines the block design and coding diagram of the wall. The construction workers only need to design and code the blocks according to the three-dimensional model of the wall. Carry out masonry according to the plan, block arrangement with high precision and fast speed, reduce block loss, improve wall masonry efficiency, ensure construction period, and reduce construction cost
