The utility model is produced and constructure scheme
1, cutting machine is used warming plate to be cut into the size of regulation.During as being designed to on-plane surface warming plate, dovetail groove need be cut out on warming plate;
2, be laid on warming plate on warming plate with the steel fabric sheet of size be cut in advance, send into assembly welding machine, adopt two-way 45 degree oblique cutting steel wires that steel fabric sheet and warming plate are formed a whole, reserve the spacing of 5-15mm between steel fabric sheet and warming plate;
3, put into anchoring piece in above-mentioned half-finished permanent position, enter mortar casting machine, the fiber reinforced cement mortar prepared is cast in spacing reserved between steel fabric sheet and warming plate, makes its thickness exceed steel fabric sheet horizontal plane 3-8mm;
4, fog room is entered by after regulation maintenance, at the reverse side sprayed-on polymer boundary mortar of warming plate, warehouse-in;
5, during construction, first the reinforcing cage that the utility model and cast-in-situ concrete are preset is fixed together, the one side of sprayed-on polymer boundary mortar is close to reinforcing cage, and the fiber reinforced cement mortar layer with steel fabric sheet is outside; The fixed mount of anchoring piece is positioned in the middle part of reinforcing cage, grip connecting bolt with cover connected nut be screwed in together with after, by fixed mount with iron wire colligation on reinforcing cage; With plank and support member, this product is fixing and after firm supporting, pour into concrete; After the number of days that maintenance specifies, remove plank and support, in-situ concrete wall and warming plate complete simultaneously, warming plate and concrete wall one integrated mass.
Compared to the prior art the cast-in-place external mold compound insulation system of a kind of fibre reinforced cement steel wire net rack of the present utility model, has following outstanding beneficial effect:
1, surface layer of the present utility model is designed to fiber reinforced cement mortar layer, has the characteristic of high-strength cracking resistance, effectively can prevent the problems such as metope cracking and relevant seepage.
2, the utility model have employed the mode that steel wire net rack penetrating type steel wire is closely linked warming plate surface layer and concrete wall, uniform force, science, and bond strength is large, and effectively can avoid wall hollow drum and the problem that comes off, safety is good.
3, the utility model employs special anchoring piece, the nylon disk of parts of plastics is embedded in fiber reinforced cement mortar layer, and the fixed mount of metallic member, in concrete wall, reduces heat transfer, and increase the bond strength of the utility model and body of wall further, make safety factor higher.
