A, on the whole type of loose tool surface, smear glass fiber reinforced plastic external mold wax, formation wax layer;
B, paving glass wool cloth layer and unsaturated polyester resin are forming the external mold surface layer on the wax layer, and each layer interlocks and carries out paving during paving;
Behind c, the external mold surface layer resin surface drying, press external mold sub-module scheme and lay shaped steel skeleton and support in the die face layer back side outside, use glass fiber layer of cloth and unsaturated polyester resin paving again on shaped steel skeleton, support and all the other external mold surface layers, and fill unsaturated polyester resin in the space between glass fiber layer of cloth and shaped steel skeleton, support, all glass fiber layer of cloths and unsaturated polyester resin solidify and close the back with fixed attention and form the glass fiber reinforced plastic external mold;
D, whole glass fiber reinforced plastic external mold is cut into different modules, different modules is taken off from the whole type of loose tool, and numbering is deposited by external mold sub-module scheme.
The cement in the described cement mortar and the proportioning of sand are 1:2; Described brick is 120 bricks.
Described external mold sub-module scheme is to carry out according to different absolute altitudes, forms vertical sub-module.Vertical sub-module in the same absolute altitude is divided into different horizontal sub-modules again.
The invention has the beneficial effects as follows:
1, the present invention makes the whole type of loose tool earlier according to design drawing, makes the glass fiber reinforced plastic external mold then on the whole type of loose tool, has reduced the cost of manufacture of glass fiber reinforced plastic external mold, has simplified its production process simultaneously, reduces its difficulty of construction, has also guaranteed the precision of external mold simultaneously.
2, the present invention is provided with the external mold surface layer of glass fiber layer of cloth and unsaturated polyester resin paving moulding at the nexine of glass fiber reinforced plastic external mold, can make the surface of special-shaped concrete shell slick and sly smooth like this, reaches the clear-water concrete effect.
3, the present invention adopts glass fiber layer of cloth and unsaturated polyester resin and shaped steel skeleton to close with fixed attention, therefore the glass fiber reinforced plastic external mold intensity height of making can guarantee the safe construction of large-sized special-shaped concrete shell and long service life, can reuse, reduce use cost.
4, the present invention cuts shell according to different level, form different vertical sub-modules, and vertical sub-module of same absolute altitude can also cut into a plurality of horizontal sub-modules, each sub-module is label respectively, be convenient to installation and removal like this, also be convenient to simultaneously store and transportation, reduce use cost.
5, the present invention adopts the sub-module assembling glass fiber reinforced plastic exterior sheathing of socket form moulding, can finish the concrete formation of large-sized special-shaped concrete structure three-dimension curved surface housing, a difficult problem that has solved steel, wooden form difficult forming and involved great expense.
6, the present invention is applied widely, is applicable to the making of different large-sized special-shaped concrete shell external molds, particularly is applicable to the making of various ball concrete shell external molds, has good society and economic benefit after the popularization.
