Abstract
The utility model discloses a PCM light foaming material internal mold with a hard reinforcing layer, which is composed of a body, the reinforcing layer and a sealed layer. Filler body materials in the inner mold are light foaming materials (such as polyphenylacetylene aerated plastics, polychloroethylene aerated plastics and polyurethane aerated plastics), the hard reinforcing layer is coated or pasted on a main stressed surface of the filler in construction, and finally a layer of sealed layer is twisted or painted around the body. The light expanded material internal mold has light weight, low manufacture cost, and certain strength, rigidity and tenacity, the light foaming material internal mold is not easily deformed and cracked in construction, the water absorption ratio is low, and the surface is smooth and is easy for concrete to flow. The light foaming material internal mold has good economy and adaptability.
Description
Affiliated technical field
The utility model belongs to buildings in general constructing technology field.
Background technology
In at present building and hydraulic engineering field, large span, large volume concrete structural are more and more, in order to reduce dead load or to strengthen concrete insulation, heat insulation, sound insulation, damping effect, need place some lightweight fillers in the concrete the inside sometimes.Come the instead of part concrete can not influence the stress performance of structure substantially with lightweight filler, but the deadweight that can alleviate structure greatly.
At present domesticly developed several and be used for the filling pipe of concrete floor and applied for relevant patent, its material therefor is several big classes such as metal material, cement products, rubber or plastic products roughly, and pluses and minuses are respectively arranged during use.The metal bellows cost is higher, and foot-operated the rubbing in when construction cause bellows seaming cracking easily, and electricity, gas welding carry out operation and may burn hole if be close to bellows simultaneously.The hollow section of being made by fragile material (high-strength cement etc.) is white heavy bigger, and water absorption rate is higher, and is cracked easily when withstanding shocks load and stacking weight.Rubber or plastic hollow pipe cost are also higher, contact to cut to pieces easily with hard metal and bump cracking.If directly fill with lightweight foam material, at first the surface of material own is softer, the excessive easy deformation of external force; Secondly hard metal scratches and is easy to generate the debris contamination construction environment, even has influence on concrete pouring quality; The water absorption rate on expanded material surface is generally bigger in addition.
Summary of the invention
Have some shortcomings at prior art, the utility model mainly construction contact surface in the packing material border proposes to improve, and purpose provides a kind of lightweight foam material internal mold of PCM band hard enhancement Layer, forms a kind of new packing material.
The technical scheme that its technical problem that solves the utility model adopts is: the lightweight foam material internal mold that forms PCM band hard enhancement Layer.It by lightweight foam material body, hard enhancement Layer, wrap up in sealant outward and constitute.The bulk material of filling member is lightweight foam material (as polystyrene foam plastics, Vestolit, a polyurethane foam plastics) in the utility model, and the main stress surface (upper and lower surface) of filling member is smeared or pasted the hard enhancement Layer in construction; Filling the winding of pipe border or brushing one deck sealant at last.
The utility model light weight, cost are low, have certain intensity, rigidity and toughness, and not yielding, cracked during construction, water absorption rate is low, smooth surface is easy to concrete flowing.And transverse shape is more flexible, can determine according to designing requirement.The utlity model has excellent economy and applicability.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model cross-sectional configuration figure.Among the figure: 1. body, 2. sealant, 3. enhancement Layer.
Fig. 2 is a body cross sectional shape schematic diagram in the utility model, and its cross sectional shape has 4. polygons, the 5. composite figure of straight line and camber line.
The specific embodiment
The utility model is to realize in such a way:
1, the utility model comprises a body (1), has a sealant (2) around the body, has enhancement Layer (3) between sealant and the body.
2, be mother metal at first, produce the body of filling member with lightweight foam material (as polystyrene foam plastics, Vestolit, polyurethane foam plastics).
3, the section of body and longitudinal size are according to designing requirement, and its cross sectional shape can be polygon (4), also can be the composite figures (5) of straight line and camber line.
4, determine the filling member main stress surface (being generally upper and lower surface) in when construction, smear at the stress surface place of lightweight foam material body or paste the hard enhancement Layer.Hard enhancement Layer intensity is higher, can bear the trample of personnel in the construction and the common collision of hard objects.The generation type of hard enhancement Layer has directly smears and paste two kinds: the first is directly smeared after hardening material (as the sticky cement screed with built-in grid) and is formed; It two forms for pasting flaky material (as cement board, hard plastic sheet, high-density plate, pottery or sheet metal).
5, twine or brushing one deck sealant in filling member body border.The sealant material should have certain intensity and toughness, its water absorption rate low (can not reduce concrete strength), smooth surface (being easy to concrete flowing); Sealant is in order to guarantee that lightweight foam material does not directly contact with concrete, and further protection lightweight foam material body is not cracked in construction simultaneously.The formation of sealant can be to form by brushing paint (as polyurethane coating, emulsion paint or elastic composite coating), also can directly be entwined with plastic adhesive tape.
Claims (4)
1, the lightweight foam material internal mold of PCM band hard enhancement Layer comprises a body (1), it is characterized in that having a sealant (2) around the body, has enhancement Layer (3) between sealant and the body.
2, the lightweight foam material internal mold of PCM band hard enhancement Layer according to claim 1, the cross sectional shape that it is characterized in that body is the composite figure of polygon and straight line and camber line.
3, the lightweight foam material internal mold of PCM band hard enhancement Layer according to claim 1 is characterized in that enhancement Layer is positioned on the main plane of constraint of body.
4, the lightweight foam material internal mold of PCM band hard enhancement Layer according to claim 1 is characterized in that sealant is a rubberised layer.
