After the concrete pouring of the construction layer is completed and the required strength is achieved, the prefabricated staircase 13 can be hoisted, after the prefabricated staircase 13 is installed, stair steps, skirting surfaces and side surfaces are protected in time by using waste templates, damage is avoided, and the construction of the assembly type building is completed layer by layer according to the method.
In this example, because the location of prefabricated component such as prefabricated wallboard 1, prefabricated superimposed sheet 7, prefabricated staircase 13 is the major difficulty of construction management, if there is the deviation in the installation to construction quality and the whole stability of structure cause adverse effect. In order to ensure that the prefabricated component is accurately positioned, the part is installed in an auxiliary manner by using a mixed reality technology, namely, an MR technology, a 3D MAX software tool is firstly adopted for building a construction model, a development environment is arranged in a Visual Studio software tool, a Unity software tool is used for building a 3D template after the environment is arranged, for example, the 3D template can be changed into a Universal Windows Platform, an MRTK development tool is introduced into the 3D template, the construction model is introduced into the 3D template, a Unity engineering package is led out to the Visual Studio development software after the construction model is functionally programmed, a MR device, for example, a mixed reality head mounted display, is used for setting a corresponding anchor point in the real world (the anchor point tracks a specific posture in a physical environment, an object is fixed at the selected point after the anchor point is added, so that the object cannot be moved, the tracking precision of a surrounding area is optimized, the construction model is kept in place relative to the real world, the MR device is used for reading, the construction worker can determine that the installation position of the prefabricated component is accurately positioned after the installation of the HoloLens, and the prefabricated component is accurately installed after the construction glasses are hung and the installation of the prefabricated component is accurately coincided.
In conclusion, the construction scheme of the prefabricated components related to the fabricated building is standardized and normalized, so that the quality of the construction engineering is improved, the construction period is shortened, and the construction cost is reduced.
Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
