Description

Technical Field

[0001] The utility model belongs to the technical field of house construction, and more specifically relates to an assembled floor slab installation structure based on BIM technology. Background Art

[0002] BIM technology is a digital tool used in engineering design, construction, and management. By integrating the digital and information models of buildings, it is shared and transmitted throughout the life cycle of project planning, operation, and maintenance, so that engineering and technical personnel can correctly understand and efficiently respond to various building information, provide a basis for collaborative work for the design team and all parties involved in the construction, including construction and operation units, and play an important role in improving production efficiency, saving costs, and shortening construction periods. Prefabricated buildings are buildings assembled on site from prefabricated parts and components. Prefabricated buildings have outstanding characteristics such as energy saving and environmental protection, fast construction, controllable costs, safety and durability. Therefore, prefabricated buildings based on BIM technology have high production efficiency and corresponding component cost reduction due to the standardization of design and informatization of management, standard components, and corresponding reduction in component costs. With the digital management of the factory, the cost performance of the entire prefabricated building will become higher and higher. Using BIM technology, analyzing the stress during floor slab installation and collecting feedback on technical issues, and designing a floor slab installation structure that is easy to install and adjust and reduces the impact of installation errors on construction is an important and indispensable research direction for prefabricated buildings.

[0003] For example, a prefabricated building floor installation structure with patent application number CN202022052572.8 includes a bottom plate layer, grooves are provided on both sides of the bottom end of the bottom plate layer, and a fixing mechanism is connected in each groove. Each fixing mechanism runs through the bottom plate layer, the sound insulation board and the steel bar layer. The bottom plate layer, the sound insulation board and the steel bar layer constitute the floor plate, and the bottom end of each fixing mechanism is connected to a connecting block, and the bottom end of each connecting block is connected to a fixing plate, and the upper ends of the fixing plates are connected to a slide frame on both sides, and each connecting block is connected to a slider on both sides, and each slider is connected to the slide frame, and the bottom end of each fixing plate is connected to a side plate, and each side plate is connected to a fixing bolt. The utility model adjusts the spacing between the two side plates so that the opposite sides of the two side plates are in contact with the wall, and then fixes the side plates to the wall by fixing bolts, thereby fixing the floor plate, and the floor plate installation is simple.

[0004] Although the above-mentioned prefabricated building floor installation structure is simple to install, there is still a problem of large installation error during installation, which affects the installation efficiency. Utility Model Content

[0024] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0025] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the product or system including the elements.
