The specific embodiment
Below in conjunction with specific embodiment the present invention is described in further details.
General face brick specification is less when adopting ceramic tile as finish coat in the common building exterior wall heat-preserving system, and in the decoration for vertical face of outer wall of some top-grade buildings, usually adopt large size ceramic tile or stone material as finish coat, as shown in Figure 1, this large-size face brick that uses outside body of wall 14 need add steel frame 3 as bearing system when constructing outside heat-insulation system 2, the interspersed again connector 5 in centre, heat-insulation system is often finished by different operation teams and groups even subpackage unit with Ceramic Tiles facing system, efficiency of construction is low, high material consumption, the integrated cost height, connector 5 can cause certain destruction to insulation layer between 3 of reinforcing bars and the agent structure when passing through heat-insulation system, reduces heat insulation effect.
Concrete construction sequence of the present invention is as follows: in-depth design → unwrapping wire and base treatment → installing and locating part (dividing pre-buried and rear-mounted two kinds) → installation steel frame → bonding applique surface brick → fill out filling polyurethane → surfacing.
1, in-depth design: by consulting architectural design drawing and reconnaissance trip, deepen design, determine the specification, spacing of face brick 4, steel frame 3, keeper 6 etc.
2, unwrapping wire and base treatment: according to designing requirement, on agent structure, eject the steel frame 3 and keeper 6 positions line, and body of wall 1 basic unit is repaired, satisfy the requirement of surface finish allowable variation ± 5mm.If what keeper 6 adopted pre-buried mode only need check keeper 6 dimensional errorss.
3, installing and locating part: as shown in Figure 3, keeper 6 by the unit of plastic 7 that is used for bridge cut-off, be used to install the steel sheet 13 of steel frame 3 and be used for being fixedly coupled three of parts 50 (being generally bolt) part and form with body of wall, connect by prepared screw-bolt hole 8, connecting bolt is embedded in when main structure construction in the body of wall 1, guarantees that by regulating unit of plastic 7 thickness steel sheet 13 is on same vertical plane when keeper 6 is installed.
Conditions permit, keeper 6 should be embedded in the main body when main structure construction, should control the installation site of keeper 6 when pre-buried well, particularly vertical and upright position, keeper 6 should be preset U type hole with steel sheet 13 connecting holes.
4, steel frame 3 is installed: as shown in Figure 4, steel frame 3 is fixed on the agent structure by keeper 6, its two ends must be provided with keeper 6, vertical skeleton 9 spacing L should determine according to face brick 4 specifications when design, make face brick 4 seams all in vertical skeleton 9 surperficial centre positions, and satisfy the requirement that face brick 4 is resisted horizontal impact loads and wind load, generally about 400mm.The present invention selects for use square steel as vertical skeleton 9, and square steel utilizes bolt to pass through keeper 6 to link to each other with agent structure.Cross binding 10 welds at vertical skeleton 9, and the one side surface keeps concordant with vertical skeleton 9, keeps a determining deviation between opposite side and the body of wall 1.The reply welding position carried out preservative treatment after steel frame 3 installed.
5, the bonding applique surface brick 4: as shown in Figure 5, face brick 4 can adopt special-purpose adhesive, and structure glue is adopted in suggestion, directly sticks on the steel frame 3, and 12 in Ceramic Tiles centre position is sticking, the not little 6cm of bonding area
2, both sides seam crossing 11 is full sticking, prevent to overflow the pollution metope when irritating polyurethane filling out, during stickup from down and on successively carry out.
6, fill out filling polyurethane: polyurethane is formed by two kinds of raw material scenes of AB system of mixing, and the combination material that the A component is formed for additives such as combination polyalcohol and blowing agents is commonly called as white material; B component main component is the raw material of isocyanates, is commonly called as black material; When system was mixed at the scene, ratio stirred A, B material in bucket according to the rules, and proportional error is controlled within 4%.After treating face brick 4 bonding adhesive setting and hardenings, 4 transverse joint places completely tape at face brick, prevent that polyurethane from overflowing, then with nozzle specially used insertion face brick 4 in the polyurethane coating construction and the space between the body of wall 1, carry out polyurethane and fill out filling, once fill out filling and be no more than 3 blocks of face bricks, 4 height, and be no more than 1.5m.
7, surfacing: face brick 4 surfaces are found to pollute and will be cleaned immediately, treat to carry out after other operations are finished jointing and handle, and with rag face brick 4 surfaces are wiped clean at last.
Above-mentioned construction technology obtain as shown in Figure 2 heat-insulation system 2 and the structural representation of the exterior wall heat-preserving system that unites two into one of face brick 4 systems.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
