Description

Technical Field

[0001] The utility model relates to the technical field of building construction tools, in particular to a quick-disassembly and installation construction device for a post-cast strip of an assembled composite slab based on the BIM technology. Background Art

[0002] BIM technology is a building information model. Based on BIM technology, after using the composite slab, the composite slab needs to be easily disassembled and installed to increase the work efficiency of the construction. After searching, the patent with announcement number CN218881607U discloses a reinforcement device for the post-cast part of a composite slab that is easy to install and disassemble, and relates to the technical field of construction tools, including a composite slab body; the lower positioning template is arranged above the transverse support beam; longitudinal pillars, the longitudinal pillars are supported below the transverse support beam; a composite slab body, the lower surface of the composite slab body is fitted and connected to the upper surface of the lower positioning template; it has a convenient installation and fixing structure, which can fix the two end faces and the upper surface of the post-cast strip. The fixing method is simple and convenient for demolding, which greatly improves the efficiency of installing and disassembling the template on the post-cast strip formed by the installation of the composite slab, and ensures that the template has a certain firmness. The fixing structure can be used multiple times, which solves the problem that during the pouring process of the post-cast strip formed by the installation of the traditional composite slab, when installing the casting template, the common method is to directly use steel nails to fix the template, which increases the difficulty of installing and disassembling the template. However, when the composite slab is being installed, the length of the longitudinal pillars is fixed when they support the main body of the composite slab. After the pouring work is completed, the composite slab is squeezed by the poured concrete and the longitudinal pillars, so that the longitudinal pillars can only move horizontally. At the same time, there is friction between the concrete and the composite slab, which makes it difficult to move the longitudinal support rods and the composite slab, thereby reducing the overall utilization efficiency of the device.
