After asking the arrangement for carrying out pipeline and embedded part and connection, formed with cementing material filling build-in；Preferential recommendation uses 1:2.5 or 1:3
Filling build-in of the cement mortar as installation extra play, the thickness for installing extra play is identical as the maximum gauge of embedded part.
The structure sheaf is the main stress layer of prefabricated hollow wall panel, is concrete hollow made of batch production is prefabricated
Wallboard, preferential recommendation are made of the hollow steel bar concrete slab of 120-200 millimeters thicks, there is a plurality of perforative circle from top to bottom
Hole, 80-140 millimeters of Circularhole diameter, centre-to-centre spacing 160-200 millimeters of hole, lateral opening hole back gauge edges of boards are not less than 100 millimeters；Knot
Bury two hanging rings at the top of structure layer, the position of structure sheaf plate width direction at edges of boards about 1/4, in thickness direction
Centre, and at the center of holes distance；Structure sheaf both sides are each to bury two pendants, as prefabricated hollow wall board and building frame
Connector setting between trestle or shear wall；The embedded height of pendant is located at the height about 1/4 of prefabricated hollow wall panel
The intermediate position of thickness direction, interior outside are consolidated with installation extra play, insulating layer respectively.
The insulating layer is attached to the level of structure sheaf outer surface, and thickness is 20-25 millimeters；Preferential recommendation uses
Extruded sheet makes, and is not limited to extruded sheet, other heat preserving and insulating materials are also in the row of the design of the present invention；Insulating layer is completely layered on structure
Layer outer surface.
The enhancement layer is the stress level on structure sheaf across insulating layer nail joint；Preferential recommendation uses steel wire system
Make, the load of exterior decoration layer is mainly directly passed to the device of insulating layer, otherwise hollowing cracking will occur for exterior decoration layer；
Nail for nail joint enhancement layer uses cement steel nail, and the length of nail is 25-30 millimeters.
The component that prefabricated hollow wall board is connect with column when the pendant is installation, including anchor rod and hook two parts,
Anchor rod is perpendicular to the straight-bar of structure sheaf side, and rod end has a ring of 40-50 millimeters of diameter, anchor rod and hook latch closure in succession at
Whole, preferential recommendation uses the reinforcement fabrication of 25-30 millimeters of diameter, and anchor rod one end is embedded in the inside 150-200 of structure sheaf
Millimeter, anchoring ring is 30-40 millimeters exposed, and the hook other end is connect with the column of building when mounted.
The hanging ring includes latch closure and bail two parts, and latch closure is linked to be entirety with bail, and preferential recommendation uses diameter 25-
The depth of 30 millimeters of reinforcement fabrication, 150-200 millimeters of latch closure central diameter, the inside of bail bending embedment structure sheaf is not less than
200 millimeters, bending length is not less than 150 millimeters；Latch closure is exposed at the top of structure sheaf.
The embedded part is made of water heating air built-in pipe and electric wire built-in pipe, and preferential recommendation uses rigid plastics control
Make；The internal diameter of water heating air built-in pipe is not less than 30 millimeters, and the internal diameter of electric wire built-in pipe is not less than 29 millimeters, wall thickness 1.5-2.0 millis
Rice；Embedded part is horizontally embedded in structure sheaf, and one end is exposed at the both sides of structure sheaf, and the other end is connected to installation preformed hole；Installation
When, corresponding pipeline is passed into preformed hole in embedded part.
The installation preformed hole is by installation switch preformed hole, installation wiring board preformed hole and installation pipe fitting preformed hole group
At；Preferential recommendation uses 50 millimeters of length and width, the square hole that 30-50 millimeters of depth；By corresponding switch enclosure, plug wire hole when boxing out
Box, faucet base box etc. are embedded in installation preformed hole；Preformed hole is installed and passes through interior decoration layer and installation extra play and embedded part
Connection, the positions and dimensions size for installing preformed hole are corresponding with the positions and dimensions size of device to be installed.
The preparation method of the prefabricated hollow wall board is first to make structure sheaf, respectively in structure sheaf after acceptance(check)
Interior outside setting installation extra play 1, insulating layer and enhancement layer, are arranged the coat of plaster and exterior decoration layer of interior decoration layer after acceptance(check)
Coat of plaster, in the face layer of architectural surface and the exterior decoration layer of construction interior decoration layer after agent structure is installed and is checked and accepted.
The making of the structure sheaf is, with cementitious matter, aggregate, enhancing material, filler material, additive, admixture, plasticizers
32.5 grades of ordinary cements of 275kg or 42.5 grades of the ordinary cement of 223kg are used with materials, preferential recommendation cementitious matters such as water,
Aggregate is enhanced material and is adopted using the silicon ash of 1-2kg, filler material using the Machine-made Sand of the slag rubble and 346-421kg of 764-832kg
With 5-10 millimeters of building waste 326kg of grain size, additive uses high efficiency water reducing agent 0.25-0.73kg, admixture to use than table
Area is 550-590m2/ kg, volume are the ground slag of 225kg, and plasticizers use volume for the air entraining agent of 0.54kg, through mixing
It makes, pour, vibrating, is steam-cured, made of cutting；Its production process is, install in a mold reinforcing bar and pendant, hanging ring, embedded part with
Preformed hole is installed, concrete is inserted into mold, after pouring molding, send steam-cured room steam-cured together with mold, after the intensity for reaching requirement
Form removal, then installation extra play, insulating layer and enhancement layer are set.
The construction of the installation extra play is carried out under natural heat dissipation to atmospheric temperature under steam curing temperature in structure sheaf,
Specific practice is that first bullet puts embedded part and installs the position line of preformed hole in the inner wall surface of structure sheaf, and embedded part is reserved with installation
The embedded part in hole is fixed on scheduled position, then fills cementing material, is conserved after floating, then interior decoration layer of constructing coat of plaster, apply
Working hour pays attention to that in embedded part and installation preformed hole mortar must not be entered.
The insulating layer and enhancement layer construction are carried out after structure sheaf form removal；Specific practice is to have cleared up structure sheaf
Wall face side after, adhesive insulating layer, and in the outside nail joint enhancement layer of insulating layer, insulating layer and enhancement layer is made to be fixedly arranged at knot
The outer surface of structure layer.
The outer surface for being fixedly arranged at structure sheaf when the coat of plaster construction of the exterior decoration layer in insulating layer and enhancement layer is laggard
The plastering layer thickness of row, preferential recommendation exterior decoration layer is 7-14 millimeters, and the coat of plaster of exterior decoration layer is made to be completely covered on enhancement layer
Outer surface.
