A kind of external thermal insulated wall frame structure
Technical field
The utility model belongs to section bar technical field for building, particularly relates to a kind of external thermal insulated wall frame structure.
Background technology
China's highrise building is more and more, owing to cold in winter, is the thermal property that strengthens house wall, and common practice is to add polyphenyl plate as insulation layer at body of wall.Though it reaches certain heat insulation effect, this product very easily catches fire.A lot of fire incidents that cause because of polyphenyl plate have taken place in China, and for this reason, the Ministry of Public Security and dwelling house town and country construction portion unite and issue a notice, the above building of 100m must reach A level fire-protection standard, and just work brings difficulty to wall thermal insulating for this, has increased construction cost, and its life-span is short, about 20 years.So the insulated wall that the i.e. insulation of research is prevented fires again and the life-span is long is extremely urgent.
The utility model content
In order to solve the problem of above-mentioned existence, the utility model provides a kind of external thermal insulated wall frame structure.It is high insulating effect not only, and has fireproof performance, long service life.
The purpose of this utility model is achieved through the following technical solutions:
A kind of external thermal insulated wall frame structure; comprise that the cross section is the insulation framework and the warming plate of I shape; during use; warming plate is arranged in the I shape groove of adjacent two insulation frameworks; the insulation framework is by being bolted on the body of wall; guard shield outside insulation is provided with on the frame outer, warming plate and body of wall and warming plate and outside two air grooves that coordinate between guard shield.
Described cross section is to be guard shield on the I shape both sides of insulation framework of I shape, is filled with in rock wool, mineral wool or the glass wool of typing one or more in it and mixes heat insulating materials, which is provided with the through hole that is used for erection bolt.The I-shaped length of side A of described insulation framework is 100-200mm, and recess width B is 30-40mm.Described warming plate is to be filled with in mineral wool, rock wool or the glass wool of typing one or more to mix heat insulating materials between first aluminium foil layer and interior guard shield.Guard shield also is provided with second aluminium foil layer near a side of insulation framework outside described.Described outer guard shield, guard shield and interior guard shield are PLASTIC LAMINATED.The guard shield top layer also is provided with surface decoration layer outside described.
Advantage of the present utility model and good effect are:
The utility model is arranged on warming plate in the I shape insulation frame groove, warming plate and body of wall and warming plate and outside coordinate between guard shield two air grooves, then the thermal resistance R=0.26m of every air groove
2K/w, i.e. the thermal resistance R=0.52m of two air grooves
2K/w is equivalent to the thick heat insulating material of 30mm.Be one or more heat insulating materials in rock wool, mineral wool or the glass wool of typing in insulation framework and the warming plate, heat insulation effect significantly and have a fireproof performance.In insulation framework both sides the flameproof protection plate is set,, and increases the intensity that is incubated framework with the heat insulating material in the middle of protecting.Be provided with flameproof protection plate and aluminium foil layer in the warming plate both sides, protecting the unlikely breakage of heat insulating material in it, and have fireproof performance, the guard shield inboard is provided with aluminium foil layer outside, to strengthen heat-insulating property.The utility model is simple in structure, and is easy for installation, long service life.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1: as shown in Figure 1; the utility model comprises that the cross section is the insulation framework 4 and the warming plate 5 of I shape; during use; warming plate 5 is arranged in the I shape groove of adjacent two insulation frameworks 4; insulation framework 4 is fixed on the body of wall 1 by bolt 2; guard shield 8 outside on the external surface of insulation framework 4, being provided with, warming plate 5 and body of wall 1 and warming plate 5 and outside 8 of guard shields, two air grooves 10 that coordinate.
As Fig. 2, shown in Figure 3, be guard shield 41,44 on the I shape both sides of the insulation framework 4 that this routine middle section is an I shape, the rock wool that is filled with typing in it which is provided with the through hole 43 that is used for erection bolt 3 as heat insulating material 42.The I-shaped length of side A that wherein is incubated framework 4 is 100mm, and recess width B is 30mm.Described warming plate 4 is at first aluminium foil layer 3 and 6 mineral wools that are filled with typing of interior guard shield, and first aluminium foil layer, 3 ends are placed near body of wall 1.Outer guard shield 8 described in this example, interior guard shield 6 and guard shield 41,44 are PLASTIC LAMINATED.
Embodiment 2: its structure is identical with embodiment 1 structure, and different is: the top layer of guard shield 8 also is provided with surface decoration layer 9 outside described.The mineral wool that is filled with typing in insulation framework 4 is filled with the glass wool heat insulating material of typing as heat insulating material 42 in warming plate 4.
Embodiment 3: its structure is identical with embodiment 1 structure, and different is: guard shield 8 also is provided with second aluminium foil layer 7 near a side of insulation framework 4 outside described.The top layer of guard shield 8 also is provided with surface decoration layer 9 outside described.The glass wool that is filled with typing in insulation framework 4 is filled with the rock wool heat-preservation material of typing as heat insulating material 42 in warming plate 4.
Embodiment 4: its structure is identical with embodiment 3 structures, and different is: the top layer of guard shield 8 also is provided with surface decoration layer 9 outside described.In insulation framework 4 and warming plate 4, all be filled with one or more heat insulating materials in rock wool, mineral wool or the glass wool of typing.
