The size limit value for breaking through prefabrication eliminates the multiple lifting and transport of wallboard, and construction method sequencing, speed of application are fast,
The beautiful multiplicity of wallboard outer surface effect；Lifting is using automatically-unhooked so that construction safety, temporary support and ground are proposed with hammer
It hits expansion bolt and is connected to precoat terrace or anchoring pile, so that temporary support is more firm.
Wherein, in above-mentioned steps S01, the terrace region for making prefabricated panel is determined, comprising:
The place of construction site meet all prefabricated panels simultaneously it is prefabricated, first pour indoor cushion as the terrace area
Domain；Or
The place of construction site is limited, first pours a region as the terrace region, the small prefabricated panel of size is borrowed
The prefabricated panel for helping size big carries out prefabricated.
Specifically, the terrace region of prefabricated panel is determined according to construction place and wallboard layout drawing and specification, and
Bed die (corresponding wallboard outer surface) for prefabricated panel；
A can be used and first be poured if building yard meets all wallboards simultaneously prefabricated (for example, for warehouse, workshop etc.)
Build indoor cushion；
B can pour a region for prefabricated panel if building yard is limited, meanwhile, the small wallboard of size can be with
It is carried out by the big wallboard of size prefabricated；
C, if the temporary support of prefabricated panel is anchored in the terrace in installation region, concrete used by the terrace etc.
Grade and thickness need to reach design requirement；
D needs prefabricated panel terrace to meet certain flatness (2 meter Nei Gao to guarantee the appearance of prefabricated panel
Difference is no more than 3mm) and smoothness (before concrete reaches initial set, repeatedly smearing pressure)；
E, ponding in order to prevent, can appropriate slope, drained.
In above-mentioned steps S02, after installing the template of prefabricated panel in the terrace region, further includes: prefabricated
It is fixed for connecting the connection embedded part of adjacent prefabricated panel in the template of wallboard, fixes appearance effect in the template of prefabricated panel

In above-mentioned steps S05, the temporary support is connect with the terrace in the installation region, comprising:
A, fixed temporary support, preferably by the terrace of the temporary support and the installation region using hammering expansion bolt
It is anchored, if without the fixation of terrace and temporary support anchoring pile can be used, present invention simultaneously provides the selections of common anchoring pile
Table see the table below 1；
B using level, while adjusting temporary support, guarantees the verticality of wallboard and the levelness at top；
C can remove temporary support after prefabricated panel and fixed other structures.
Table 1
Below in conjunction with specific embodiment, the prefabricated construction method of large scale wallboard of the present invention is described in detail.
By taking the library Prologis Logistic Park A3 of Liuyang as an example, building is 240 meters long, and width is 95 meters, and column is away from being 12 meters, span 24
Rice, cornice absolute altitude are 10m, which introduces North America Tilt-up building system, are mixed using steel construction and concrete wall
Structure, outer curtain wall penel participate in whole stress, and wall-plate level is up to 14.6 meters.The prefabricated construction of large scale wallboard of the present invention
The construction procedure of method, prefabricated panel is as follows:
(1) this project first pours indoor cushion, strength grade of concrete C30, with a thickness of 150mm, the flatness of bed course
Requirement is substantially met with smoothness；
(2) unwrapping wire, including template, wallboard appearance mold connect embedded part, fixed temporary support with other structures component
Sleeve embedded part and facial suspension centre embedded part, setting connection embedded part between the wallboard of interlayer Office Area；
(3) fixed side form template, this project use channel steel steel form；
(4) moulding and chamfering item use solid wood, and wherein chamfering item is bonded using double-sided adhesive and channel steel, and moulding is adopted
It is fixed with nailing and indoor cushion；
(5) Liuyang City is rainy, therefore uses clear water release agent；
(6) reinforced mesh makes:
A makes reinforced mesh using electric welding；
B arranges the stirrup of lower layer's reinforced mesh, and spacing is no more than 1 meter between stirrup, then by lower layer's hoisting steel mesh piece
In place,
C cuts the place of door-window opening according to openings position；
D arranges top bars mesh sheet stirrup, places top bars mesh sheet；
E, hole and panel edges are bound using steel wire；
F replaces silent stirrup using two-way opening stirrup for constructing edge member；
(7) fixation of embedded part, for facial suspension centre embedded part, additional bar needs (must not be by reinforcing bar according to design requirement
Welded with suspension centre embedded part), temporary support embedded part sleeve and suspension centre embedded part rubber sleeve (surface spraying release agent) are fixed；
(8) concreting, this project use strength grade of concrete for C45, slump 18cm；
(9) concrete surface flattens, polishing and maintenance；
(10) when R.C. wall board strength grade reaches 70%, the rubber sleeve in step (7) is taken out first, it is fixed simultaneously
Then hanging buckle connector is connected by the connection of temporary support and wallboard with suspension centre embedded part；
(11) wallboard lifts by crane, and when just demoulding is lifted by crane, needs slowly to operate crane, lifts by crane repeatedly, after wallboard demoulding, utilizes height
Pressure hydraulic giant is rinsed surfaces of wall；
(12) temporary support is fixed with indoor cushion using hammering expansion bolt, using level, is adjusted simultaneously
Temporary support guarantees the verticality of wallboard and the levelness at top.
On the one hand the prefabricated construction method of large scale wallboard of the present invention makes full use of place, separately using in-situ precast
On the one hand the size limit value for breaking through prefabrication saves wallboard in multiple lifting and transport；Lifting using automatically-unhooked so that
Construction safety, temporary support and ground are proposed with hammering expansion bolt and are connected to precoat terrace or anchoring pile, so that temporary support
It is more firm.The sequencing of this construction method, speed of application are fast, shorten construction period, wallboard outer surface effect beauty multiplicity etc..
The prefabricated construction method of large scale wallboard of the present invention, large-size reinforcement bar concrete panel use in-situ precast,
Width is unrestricted, determines its economic width by building requirements or structure design, if wallboard participates in whole stress, highly may be used
To reach 18 meters.Wallboard installation using face overturning lifting, while realize it is automatically-unhooked, can be to avoid high altitude operation, using can
Adjusting supports temporary support effect.Therefore, large-size reinforcement bar concrete panel construction requirement is high, and difficulty of construction is big, further relates to
The selection of auxiliary products.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, in the range of not departing from technical solution of the present invention, when the technology contents using the disclosure above are modified or are repaired
Decorations are the equivalent embodiment of equivalent variations, but anything that does not depart from the technical scheme of the invention content, technology according to the present invention are real
Matter any simple modification, equivalent change and modification to the above embodiments, still fall within the range of technical solution of the present invention
It is interior.
