Further, the decoration panel lateral surface has decorative coveringn.
The beneficial effects of the present invention are:Decoration panel is connected by the present invention with bottom plate by connector, constitutes insulation dress
Adorn filled board, connector can reliable delivery act on the wind load of decoration panel, it is to avoid panel comes off, and in connector and bottom
The junction of plate sets the adhesive mortar with certain bearing load and transmission weight bearing power, and the wind load that connector is transmitted is entered
One step is directly delivered to wall by adhesive mortar, it is ensured that system power transmission is directly, reliably, it is ensured that safety.The present invention can be realized
Heat preservation decoration integrative, it is ensured that construction quality, speeds up the work, and ensure in Energy Conservation Project in Construction it is safe and reliable should
With.

Embodiment
As shown in figure 1, the present invention is a kind of to decorate the sandwich board exterior wall outer thermal insulation of insulation and decoration that panel is mechanically connected with bottom plate
System, the system includes insulation and decoration filled board, adhesive mortar 5, anchoring piece 6 and fluid sealant;The insulation and decoration filled board
Including decoration panel 3, bottom plate 1, connector 4 and insulation material 2 between bottom plate 1, decoration panel 3;Before the connector 4
End decoration panel 3 is connected, and rear end is connected with bottom plate 1, can reliable delivery act on the wind load of decoration panel, it is to avoid panel is de-
Fall.
Connector 4 and the junction of bottom plate 1, the back side of bottom plate 1 are bonded by adhesive mortar 5 and wall, the adhesive mortar 5
The distance between edge and connector 4 and the tie point of bottom plate 1 p is not less thanPreferably, adhesive mortar 5 constitutes diameter
5 is a diameter ofRound pie, as shown in Figure 3.Wherein, F is connected tensile capacity for decoration panel 3 with the single-point of bottom plate 1,
S is the adhesion strength of bottom plate 1 and wall, according to leading professional standard《Architectural engineering cohesive strength of decorative tile test stone》
JGJ110 is tested, and K is the partial safety factor for resistance of adhesive mortar 5, in the prior art, generally takes 2.5.Meet above-mentioned requirements
Adhesive mortar 5, can just be effectively ensured the conducting power of adhesive mortar, and the wind load for effectively transmitting connector 4 further passes through
Adhesive mortar 5 is directly delivered to wall, it is ensured that system power transmission is directly, reliably, it is ensured that safety.Preferably, the connector 4 with
Bottom plate 1 is connected by tapping screw 7, and the tapping screw 7 passes through bottom plate 1, end and the metallic gasket for being arranged on the back side of bottom plate 1
8 are connected, and improve the connection bearing capacity of tapping screw 7 and bottom plate 1, it is to avoid tapping screw 7 is transferred to from bottom plate 1.
Bottom plate 1 and wall also are made further to be connected by the bottom plate 1 of the insulation and decoration filled board by anchoring piece 6, bear
Insulation and decoration filled board is conducted oneself with dignity so that adhesive mortar 5 is subjected only to horizontal force, and wind suction prevention is contributed to completely.Two adjacent
Pass through sealant sealing between insulation and decoration filled board.Cross system above, it is possible to achieve heat preservation decoration integrative, it is ensured that engineering matter
Amount, speeds up the work, and ensure the safe and reliable application in Energy Conservation Project in Construction.
The single-point connection tensile capacity of panel 3 and bottom plate 1 is decorated by 4 kinds of connector between decoration panel 3 and bottom plate 1
The influence of the factors such as class, connector quantity, method of testing should be by existing professional standard《Insulation and decoration plate exterior wall external heat preservation system material
Material》6.3.2 bars tensile bond strength testing method is performed in JG/T 287, and should be met the following requirements:
A.1 prepared by sample
Sample is prepared and should met the following requirements:
A) size and number:Specimen size is not less than 100mm × 100mm, and the connector of decoration panel 3 and bottom plate 1 is located at
Sample center, quantity 3;
B) slot, make completely separable above and below insulation material in the middle part of the thickness of insulation material 2;
C) sample is expired using adhesive mortar and is bonded at reinforced cement-mortar board, 14d is at least conserved under the conditions of standard curing;
D) by with the metal derby of sample corresponding size with high-intensity resin adhesive bond on sample.
A.2 process of the test
Sample is installed on suitable tensile testing machine, carries out panel and tensile capacity measure is connected with bottom plate single-point,
Draw speed is (5 ± 1) mm/min.The force value and collapse state when each sample is destroyed are recorded, 1N is accurate to.As metal derby with
Sample is disengaged, and test value is invalid.
A.3 result of the test
Panel is connected tensile capacity with bottom plate single-point and represented with the arithmetic mean of instantaneous value of 3 specimen test data, is accurate to
1N。
For example, being attached between decoration panel 3 and bottom plate 1 by 6 U-shaped connectors being evenly arranged, by existing row
Industry standard《Heat insulating decorative board material for external thermal insulation system of external wall》6.3.2 bars tensile bond strength testing method is measured in JG/T 287
Its single-point connection tensile capacity F=1100N;Meanwhile, by existing professional standard《Architectural engineering cohesive strength of decorative tile examines mark
It is accurate》JGJ110 is tested, and the adhesion strength S of bottom plate 1 and wall is 0.3 × 106N/m2, according to binding sand generally in the art
The partial safety factor for resistance 2.5 of slurry 5, that is, obtain the distance between the edge and connector 4 of adhesive mortar 5 and the tie point of bottom plate 1
At least 0.054m, considers, adhesive mortar 5 can use a diameter of 0.108m round pie structure from material is saved.
The connector 4 of the present invention can be u shapes fastener, rectangular tube, z shape connectors, but not limited to this.Bottom plate 1 and decoration
Panel 3 can be joined using fiber reinforced cement board, fiber reinforced calcium silicate board etc. by the water absorption rate to bottom plate 1, density etc.
Number is adjusted, and is aided with surface modification, perforate slip casting, the adhesion strength between bottom plate and wall can be caused to reach 0.3MPa.
As common technical means in the art, the outside of decoration panel 3 opens up multiple counterbores 6, is easy to decorate panel 3
With the connection of connector 4, meanwhile, be conducive to decorating the flatness in the outside of panel 3, it is ensured that decorative effect.Outside the decoration panel 3
Side can also have decorative coveringn, to meet elevation of building design effect, lift aesthetics, and decoration panel 3 is protected,
Improve its durability.
