Prefabricated Composite Slab Reserved Hole And Magnetic Box Process Principle Based On BIM

Introduction
Prefabricated assembled stacked panels on the reserved holes face problems such as poor combination of various specialties, low efficiency of embedding, large size and position deviation, etc. Our company analyzes the construction of the project from the aspects of design, construction, etc., and adopts BIM-based prefabricated stacked panels on the reserved holes of the magnetic box positioning and installation construction technology, which solves many problems of the reserved holes of the stacked panels, and it has a very good reference significance for the construction of similar projects.

Preface

With the improvement of construction technology level and the development of modernization of the housing industry, prefabricated assembly building construction technology is an inevitable trend in the development of China's construction industry, but there are more problems in the production and construction of various components of assembly buildings, such as the problem of pre-fabricated stacked panels with pre-drilled holes, how to achieve effective combination of pre-drilled holes in various disciplines with the stacked panels; so that the use of the pre-drilled holes in the stacked panels is increased and the difficulty of pre-drilling holes is decreased in the stacked panels. It has become an important link in the development of construction industry engineering to increase the utilization rate of reserved holes in stacked panels, reduce the difficulty of reserving holes in stacked panels and improve the quality of holes reserved; minimize the deviation of reserved holes in the stacked panels above and below the floors; and shorten the time for burying the reserved holes in the stacked panels and shorten the time of the overall manufacturing of the stacked panels. Our company has adopted Shutter magnet positioning and installation technology based on BIM prefabricated laminated panel pre-drilled holes in a number of frame structure assembly construction projects, which solves many problems of pre-drilled holes in laminated panels, and has the advantages of safety, reliability, convenient operation, environmental protection and energy saving, and low comprehensive cost.

Technological principle

Firstly, the construction models of various specialties are integrated, and the positions of the reserved holes are reflected in the structural slab and checked.

Then, the professional software PKPM-BIM is used to carry out the split design of the standard floor slab, generate the prefabricated laminated plate model and steel reinforcement model, and correspondingly embody the positions of the reserved holes of all the specialties in the prefabricated laminated plate, and then carry out the force calculation of the laminated plate.

Then, the information of the split stacked plate model is imported into the infrared locator, and the infrared locator is used to locate the reserved holes on the base plate of the steel mold of the stacked plate, and then manual measurement and verification are carried out, so that the location of the reserved holes of the stacked plate has no deviation from the design drawings.

Finally, according to the size of the reserved hole for stainless steel reserved hole precast concrete magnet selection, and according to the positioning in the steel mold table for the reserved hole precast magnet fixed, so that the stainless steel reserved hole shuttering magnets one-time installation in place.
