Problems solved by technology

[0007] The purpose of the present invention is to overcome the problem that the vertical bars and stirrups of the post-casting section or edge members prevent the horizontal anchor bar exposed on the external hanging panel from entering the post-casting section or edge members during the construction of the external hanging panels in the existing overall prefabricated buildings. The current construction method has the problem that the overall strength of the external cladding is not enough or the construction cost is too high. To provide a construction method for the external cladding of the overall prefabricated building based on BIM technology. The quality of binding and forming, without increasing the cost of extra materials and man-hours, has great advantages

Embodiment 1

[0045] Such as Figure 1 to Figure 7 As shown, in this embodiment, the construction method of the external hanging panels of the overall prefabricated building based on BIM technology is used for the post-casting section construction between the external hanging panels. The specific construction steps are as follows:

[0046] (1) Hoist the external hanging plate 1 in place and temporarily fix it, and adjust the verticality;

[0047] (2) Grouting of the anchor foot of the external hanging plate 1; connect the external hanging plate with the floor slab that has been constructed, and fix the external hanging plate;

[0048] (3) install the stirrup 4 within the scope of the post-casting section, and temporarily fix the stirrup 4 and the external hanging plate 1, and the stirrup 4 is a closed rectangular stirrup;

[0049] (4) Install vertical reinforcement 5 within the scope of stirrup 4, and connect and lengthen the length of vertical reinforcement 5 according to the floor height; ...

Embodiment 2

[0061] Such as figure 1 , 13 As shown in ab3701-ef5d-4755-b1e7-a8b12eb5e519, the construction method of the external cladding of the overall prefabricated building based on BIM technology in this embodiment is used for the construction of the edge components between the cladding panels. The specific construction steps are as follows:

[0062] (1) Hoist the external hanging plate 1 in place and temporarily fix it, and adjust the verticality;

[0063] (2) Grouting of the anchor foot of the external hanging plate 1; connect the external hanging plate with the floor slab that has been constructed, and fix the external hanging plate;

[0064] (3) install stirrups 4 within the scope of the edge member, and temporarily fix the stirrups 4 and the external hanging plate 1, and the stirrups 4 are closed rectangular stirrups;

[0065] (4) Install vertical reinforcement 5 within the scope of stirrup 4, and connect and lengthen the length of vertical reinforcement 5 according to the floo...

Abstract

The invention discloses a building construction technology and provides an externally-hung board construction method for an integrally-assembled type building based on the BIM technology. The method includes the steps that externally-hung boards are hung and temporarily fixed; grouting is conducted on anchor feet of the externally-hung boards; stirrups are installed and temporarily fixed to the externally-hung boards; vertical bars are lengthened and installed; the stirrups are re-located and fixed; the concealing performance of reinforcing steel bars is checked and accepted, and supporting templates are installed; and concrete pouring is conducted. The externally-hung boards installed through the construction method are good in anti-seismic performance, the binding and forming quality of the reinforcing steel bars is guaranteed, redundant material cost and work hours are not increased, and the beneficial effects are relatively large.

Description

technical field [0001] The invention relates to a building construction technology, in particular to a construction method for an external hanging panel of an integrally assembled building based on BIM technology. Background technique [0002] Due to its high degree of industrialization, effective reduction of waste of resources, low labor intensity of workers, substantial reduction of construction labor, wide applicability, and compliance with the requirements of green buildings, integral prefabricated buildings have gradually been popularized and applied everywhere. The external hanging board is an important component in the overall prefabricated building. The connection between the parallel spliced ​​external hanging boards is the post-casting section, and the splicing of the external hanging boards perpendicular to each other is the edge member. The post-casting section and the edge member are both Pouring in situ. [0003] The post-casting section and edge members are ...
