Abstract

The utility model relates to a novel temperature preserving and sound-proof door. At present, most exterior doors and entrance doors in the market are made of steel and have a structure that an interior plate and an exterior plate of a door leaf are thin steel plates; honeycomb paper is filled between an interior and an exterior plates which are agglutinated with each other with polyfoam; and the joints of the interior and the exterior plates are formed through spot welding. As no welding point is left on the surfaces of the interior and the exterior plates, the surface quality of the doors is better, but due to the arrangement of reinforcing bars or belts, the rigidity of the door structures is not good, and the temperature preservation of the doors is not good as well. The novel temperature preserving and sound-proof door comprises a door frame (1), a door leaf (2) and a lock (3). The door leaf (2) is provided with an interior plate (6), an exterior plate (7) and a polystyrene cystosepiment (9) which is provided with a U-shaped steel frame (5) manufactured through metal band roll milling. The novel temperature preserving and sound-proof door is applicable to the building door field.

Description

The novel heat-preserving and sound-insulating door

Technical field:

The utility model relates to a kind of novel heat-preserving and sound-insulating door.

Background technology:

Building external doors and Hu Men mostly are steel door in the market, and it is steel sheet that its structure mostly is door leaf innner and outer plate, middle filled honeycomb paper, and bonding with foamed glue and innner and outer plate, innner and outer plate junction spot welding forms.The no solder joint in this door about plate surface, therefore the surface quality of door is better, but because door has the reinforcing rib band, the poor structure rigidity of door, heat-insulating property is poor.

Another kind of structure is welded with the reinforcing rib band for the door leaf back veneer; the middle rock cotton sliver of filling; outside plate and muscle band rivet welding are together during hinge; this door rigidity is better, but surface quality is poor, fills up by hand simultaneously; the splicing rock cotton sliver; be difficult to be full of door leaf fully, so heat-insulating property is poor, manual operations simultaneously also is unfavorable for large-scale production.

Summary of the invention:

The purpose of this utility model provides a kind of high insulating effect, door that sound insulation value is good.

Above-mentioned purpose realizes by following technical scheme:

The novel heat-preserving and sound-insulating door, its composition comprises: doorframe, door leaf, door lock, described door leaf has back veneer, outside plate and polystyrene foam plate, has the steel frame of the U shaped steel that the steel band rolling makes in the described polystyrene foam plate.

Described novel heat-preserving and sound-insulating door, described door leaf have the U type pick-proof seal groove of outside plate and back veneer rolling interlock formation.

Described novel heat-preserving and sound-insulating door, in the described seal groove adhesive tape is housed, the described back veneer that hinge is housed has upper and lower lock point, and described hinge, lock point are connected with door lock by bolt, described back veneer and polystyrene foam plate gluing, described polystyrene foam plate and outside plate gluing.

The beneficial effects of the utility model:

1. the utility model polystyrol plastic foam plate density only is 20kg/m ³, coefficient of thermal conductivity＜0.039W/m.k, oxygen index (OI) 〉=30%, the adhesive strength of the two assembly adhesives of PU is 28N/cm ², therefore the utlity model has excellent insulating and sound insulation value, and characteristics in light weight, that structural rigidity is good.

2. have in the middle of the utility model the polystyrene board of strengthening steel frame to adopt compression molding, size, shape are identical with door leaf, so door leaf production need not manually piece together filling, and can guarantee that door leaf all is full of.Simultaneously, adopt the roll-in interlock during plate hinge of innner and outer, need not manually weld, therefore be suitable for mechanization large-scale production.

The specific embodiment:

Embodiment 1:

The novel heat-preserving and sound-insulating door, its composition comprises: doorframe 1, and described doorframe 1 is connected with door leaf 2, and described door leaf 2 is connected with door lock 3, described door leaf 2 has back veneer 6, outside plate 7 and polystyrene foam plate 9, and described polystyrene foam plate 9 has the steel frame 5 of the U shaped steel that the steel band rolling makes.

The described back veneer 6 that hinge 10 is housed has upper and lower lock point 4, described back veneer 6 and polystyrene foam plate 9 usefulness PU double liquid glue gluings, described polystyrene foam plate 9 and outside plate 7 usefulness PU double liquid glue gluings, described door leaf have the U type pick-proof seal groove of outside plate and back veneer rolling interlock formation.

Described novel heat-preserving and sound-insulating door, it is characterized in that: described hinge 10, lock point 4 pass through bolt 12 and are connected with door lock 3, described door leaf 2 has U type pick-proof seal groove, and described seal groove is equipped with sealing joint strip 11 for 13 li, and mouth is equipped with two road sealing joint strips 8 in doorframe.

Described steel frame is rolled into U shaped steel with cold-strip steel, be welded into network-like again, described polystyrene foam plate is a raw material with the anti-flammability expandable polystyrene particle, has the polystyrene foam plate with fine hole-closing structure of steel frame in particular manufacturing craft in the middle of steel frame hot pressing is made through heating prefoam.
