Description
Technical Field
The utility model relates to a prefabricated construction equipment technical field, a prefabricated concrete side fascia concatenation seam heat preservation waterproof construction specifically says so.
Background
At present, the country attaches importance to urban innovation and green development and popularizes the assembly type building, and the assembly type building has the advantages of high industrialization degree, high construction speed, short period, excellent comprehensive economic benefit, good earthquake resistance, environmental protection, beautiful appearance and the like. The method has gradually deepened into various fields such as factory buildings, warehouses, supermarkets, markets, stadiums, office buildings and the like. However, the water leakage phenomenon of the splicing seams of the prefabricated concrete external wall panels in China is serious at present, the heat insulation performance can be reduced once water leakage occurs, and the normal use of the house is seriously influenced. Thereby becoming a difficult problem restricting the development of the fabricated building.
SUMMERY OF THE UTILITY MODEL
For seam leak, the poor problem of heat preservation among the solution background art, the utility model discloses a waterproof, effectual prefabricated concrete side fascia concatenation seam heat preservation waterproof construction keeps warm.
The utility model adopts the technical proposal that:
a prefabricated concrete external wall panel splicing seam heat-preservation waterproof structure comprises a first external leaf plate, a second external leaf plate, a first internal leaf plate, a second internal leaf plate, a first heat-preservation layer and a second heat-preservation layer; a first heat preservation layer is arranged between the first outer blade plate and the first inner blade plate; a second heat-insulating layer is arranged between the second outer blade plate and the second inner blade plate; polyurethane foam is filled between the first heat-insulating layer and the second heat-insulating layer; polyurethane foam, a foam rod and weather-resistant structural adhesive are sequentially filled between the first outer blade plate and the second outer blade plate from inside to outside; and polyurethane foaming, rubber strips and weather-resistant structural adhesive are sequentially filled between the first inner blade plate and the second inner blade plate from inside to outside.
The utility model has the advantages that: the utility model provides the high efficiency of construction of prefabricated concrete side fascia of mill, the expanded material high-usage splices the seam more closely knit, and it is better to glue shutoff heat preservation water-proof effects through resistant structure.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The present invention will be described in further detail with reference to fig. 1 and reference numerals.
A prefabricated concrete external wall panel splicing seam heat-insulating waterproof structure comprises a first external blade plate 1, a second external blade plate 2, a first internal blade plate 3, a second internal blade plate 4, a first heat-insulating layer 5 and a second heat-insulating layer 6;
a first heat preservation layer 5 is arranged between the first outer blade plate 1 and the first inner blade plate 3; a second heat-insulating layer 6 is arranged between the second outer blade plate 2 and the second inner blade plate 4;
a polyurethane foam 7, a foam rod 8 and a weather-resistant structural adhesive 9 are sequentially filled between the first outer blade plate 1 and the second outer blade plate 2 from inside to outside;
and a polyurethane foam 7, a rubber strip 10 and a weather-resistant structural adhesive 9 are sequentially filled between the first inner blade plate 3 and the second inner blade plate 4 from inside to outside.
The weather-resistant structural adhesive is silicone weather-resistant structural adhesive, and the gluing thickness is at least 10mm.
The diameter of the foam rod 8 is phi 25mm.
The rubber strip is an ethylene propylene diene monomer sealing strip.
The polyurethane foaming adopts spraying to fill the splicing seam.
The first outer blade plate, the first inner blade plate, the second outer blade plate and the second inner blade plate are made of light concrete wallboards.
A first heat preservation layer is arranged between the first outer blade plate and the first inner blade plate; a second heat-insulating layer is arranged between the second outer blade plate and the second inner blade plate; the structure is prefabricated and finished in a processing workshop.
The foaming filling process is as follows: (1) before the wallboard is hoisted, adhering the ethylene propylene diene monomer sealing strip to the first inner blade plate; (2) plugging a foam rod at the splicing seam, extruding tightly, and reserving 10mm holes for spraying polyurethane foaming glue every 600mm of foam rod; (3) and (4) spraying the foaming glue into the reserved hole from bottom to top through a compressor and a spray gun on the ground (the amount is controlled during spraying, and the foaming glue is filled into the cavity after foaming and expansion).
