Abstract

An energy-saving insulating technique by hanging plates from external surface of external wall includes preparing FP screw bolts, designing the polybenzene plates and its hanging method, choosing the gelatin material for external protection layer, and curing it. Its advantages include high firmness, simple technology, high insulating effect and low cost.

Description

Energy-saving insulating technique by hanging plates from external surface of external wall

This invention is meant implements exterior wall, cladding panel, outer heat preservation technology (WWW is first letter of three outer words, hereinafter to be referred as the WWW technology) to residential building.

Energy-saving building technology China and foreign countries heat preservation technology is domestic still rare at present, and several application the seldom only arranged.And this invention and existing technology its be different from: 1, insulation polyphenyl plate and exterior wall associated methods employing FP bolt is fixed, and has changed the existing method that adds metal screw two procedures again that sticks with glue.This invention makes that insulation layer combines with body of wall firmly, cost saving, saving man-hour; 2,4 of polyphenyl plate sides all adopt two opposite sides towards same direction inclination miter angle, lay is fixedly the time on the wall, lastblock and next piece, the first from left piece is overlap joint with one on the right side and (depresses promptly, the pressure right side, a left side) changed the method that the side an angle of 90 degrees docks the vertical masonry joint that forms between the present polyphenyl plate, and metope lays the benzene plate and do not establish lattice seam, improves heat insulation effect.3, topping uses the aluminium sulfate special cement, and the early strength height can reach 28 days intensity in 3 days, simultaneously grid cloth was not corroded, and rainwater and airborne soda acid composition are also had protective action, improved outer decorative quality, increased the service life.

The present invention technology mainly comprises

One, insulation layer and outer body of wall combination technology innovation.Only just can fix firmly, no longer with expensive a large amount of gluing connecing with 3 FP bolts.(Fig. 1)

Two, the design of FP bolt is unique.1, selection science; Employing ABS manufactures screw rod, nut, packing ring, gives full play to the material characteristics of intensity height, good rigidly, and expansion tube is manufactured with polyethylene, has the big advantage of elasticity.Find in practice, existing sticking with glue adds the metallic screw twice and sets up defences and still have some problems to be difficult to overcome, the benzene plate is different with the body of wall linear expansion coeffcient, both separate under natural temperature changes for a long time, screw corrodes undergauge frictional force during this period and shearing resistance descends significantly, once, the large tracts of land insulation layer will occur and come off, also may cause the injury and the loss of people and property at strong wind weather.And the expansion bolt of SBS and polyethylene manufacturing will can not corrode, and is securely fixed on the wall for a long time.(Fig. 2)

Three, the mutual miter angle bridging method of benzene plate science (Fig. 3).Be to have cancelled the lattice seam that between certain distance benzene plate, is provided with first, second also eliminated two boards an angle of 90 degrees butt joint vertical masonry joint, the side miter angle of lastblock is pressed in the side of next piece, and the first from left piece is pressed in right side again, conditioning each other has constituted an integral body, and tightness improves heat insulation effect well.External protection cracking or local shedding appear in Nian Jiuru, the also unlikely appearance infiltration of insulation layer, the phenomenon of breathing freely.

Four, external protection is selected sulphate aluminium cement for use, and intensity can reach 28 days intensity in 3 days, though increase on cost, few, the reduction of erection time of consumption, the fine grid cloth of glass is not corroded.Comprehensive benefit still is better than Portland cement.

Five, construction technology.1, dress watch wall face.Reach concrete or build the clay tile wall standard by laying bricks or stones and get final product, the foreign material of cleaning external surface provide a smooth smooth metope, and are much loose with gluing metope relatively, reduce by the leveling layer of wiping one's face.

2, snap the line location.Specification by polyphenyl plate is from top to bottom arranged block number one by one at metope, and by the boring of every block of plate draw boring position (Fig. 4).

3, the FP bolt is installed.By the hole site, bore 3 holes on the wall and become isosceles triangle, drilling depth 30mm, aperture 12mm also installs the FP bolt.

4, link plate.Link plate from top to bottom, from left to right, is close to upwards push-tight left again with wall from top layer, puts packing ring, tightening nuts.

5, local link plate.Unified at last the processing, the specification of the good used plate of amount, holed in a plate one hole in boring on the plate on the wall.1. all wrap with two blocks of miter angle plates at the negative and positive angle; 2. window is wrapped by external corner, and the plate perpendicular with metope is that an angle of 90 degrees plane and metope are adjacent to, and do not stay the slit.

6, do topping.1. glue, cement and low amounts of water stir on the polyphenyl plate after pulping is sprayed on the cleaning dust, are stained with in the above rapidly above the tension of 5 * 5mm glass fibre web lattice cloth pastes.2. (sulphate aluminium cement+glue+fine sand+water, promptly 3: 1: 4: 2), after 2 days, spray exterior wall waterproofing coating through maintenance, color was by designing requirement to connect the procedure gunite.

The present invention compares with existing External Thermal Insulation Technology for External, has four big advantages: the one, and insulation layer combines firmly with body of wall.The present invention adopts domestic initiation FP bolt installation polyphenyl plate firm.With adopt metal screw and gluing method fixedly the polyphenyl plate technology compare, FP bolt not burn into heat conduction is little to, linear expansion coeffcient, has more durability; The 2nd, high insulating effect.Polyphenyl plate is the miter angle overlap joint each other, no vertical masonry joint, and tightness is good.Body of wall outside time, rainwater can not leak into after topping crack or local shedding for a long time, so good heat insulating; The 3rd, technology is simple.Each procedure connection compactness, the reduction of erection time; The 4th, reduce construction costs.This technology is than existing other outer heat preservation technology reduced investments during construction, and in addition, maintenance cost is low, and overall economic efficiency is good.Thereby this invention is for popularizing the building energy conservation new standard in an all-round way---residential building 100% reaches energy-conservation 50%, breaks new road again.

Above-mentioned purpose is achieved through the following technical solutions:

One, at first builds experimental project, prove its science, advance, economic feasibility and be easy to generalization.

Two, the economic and technical norms of this technology of test from engineering are formulated technological documents such as design, construction, standards of acceptance and standard.

Claims

1, a kind of WWW energy-saving building technology, especially use nonmetal expansion bolt fixedly the technology of warming plate be an invention.Be characterized in: in conjunction with firmly, high insulating effect, technology is simple, the duration is short, cheap, be easy to popularization.It is Building technology innovation again.
