[0002] Traditional exterior wall insulation integrated walls are divided into combined sandwich insulation exterior walls, non-combined sandwich insulation exterior walls and partially combined sandwich insulation exterior walls. Among them, non-combined exterior wall insulation integrated walls are the most widely used. Non-combined sandwich insulation exterior walls are composed of inner page panels, insulation layers and outer page panels. The inner page panels bear the load, and the outer page panels are protective layers and insulation layers. The insulation work is undertaken by the insulation layer. The protective layers of the inner and outer page panels of traditional exterior wall integrated walls are both concrete, which has the problems of large weight, poor insulation, and cold bridges of stainless steel connectors. However, due to the existence of external metal keels suspended outside the insulation layer, the thermal insulation performance of traditional building aluminum curtain walls is difficult to meet the requirements of ultra-low energy consumption buildings.

[0003] Therefore, there is an urgent need in the art for an integrated exterior wall structure with a decorative thermal insulation structure that is lightweight and can achieve good thermal insulation performance. Summary of the invention

[0021] In order to make the present invention more clearly understood, a preferred embodiment is described in detail with reference to the accompanying drawings as follows:

[0022] like Figure 1 As shown, the utility model provides a composite aluminum plate decorative insulation integrated exterior wall of a non-concrete structure outer page plate, and its production process is as follows:

[0023] The outer page board 2 and the insulation layer 3 are bonded by an adhesive to form an integral outer page wallboard. A hole is opened at a preset position of the integral outer page wallboard, and the diameter matches the diameter of the composite material tie rib 7 and is 1-2mm larger than the diameter of the composite material tie rib 7. A hole with a diameter of about 4mm is opened at the outer end of the composite material tie rib 7, and the anchor plate 6 is connected to the hole at the outer end of the composite material tie rib 7 by a self-tapping screw 5 to form an integral connection anchor, and the inner end is exposed from the surface of the insulation layer 3, and the exposed length is about 50 to 150mm.

[0024] 1. Place the processed outer wall panels with connecting anchors into the mold and pour the inner panel concrete base 1 (on-site pouring: use the outer wall panels as the outer formwork, set the inner formwork reinforcement ribs and through-screws)

[0025] Second, the aluminum plate facing layer 4 is first effectively connected to the L-shaped angle aluminum 10 through the core-pulling rivet. After injecting a proper amount of structural adhesive 9 on the back and upper mouth of the aluminum plate facing layer 4 connected with the connecting angle aluminum 10, it is placed in the pre-reserved notch of the outer wall panel and adjusted in position, and then the L-shaped angle aluminum 10 is effectively connected to the inner panel concrete base 1 through the concrete screw 8.

[0026] 3. After the back and upper structural adhesive of the aluminum plate facing layer 4 is cured, the aluminum plate facing layer 4 and the outer page plate 3 can generate effective bonding strength.

[0027] 4. After the aluminum plate is installed, the structural adhesive 9 is used to seal and finish, so as to increase the overall beauty, waterproofness and sealing performance of the composite aluminum plate decorative insulation integrated exterior wall of the non-concrete structure outer page plate.

[0028] Traditional building aluminum curtain walls are difficult to meet the requirements of ultra-low energy consumption buildings due to the presence of metal keels. In order to increase thermal insulation performance, many measures are usually required, such as adding insulation pads at embedded parts to reduce cold bridges, increasing the thickness of the insulation layer, and increasing the cantilever distance of the metal keels. In order to meet the requirements of ultra-low energy consumption buildings, traditional prefabricated aluminum curtain wall structures not only need to take the above design measures, but also because prefabricated aluminum curtain walls require complex construction processes such as drilling holes to install embedded parts and backfilling insulation, they have obvious defects such as long construction period and low safety. Compared with traditional external keel aluminum curtain walls, the utility model can reduce thickness and weight while improving thermal insulation performance. In addition, this structure has a short construction period, simple construction method, low overall cost, and higher safety.

[0029] The above is only a preferred embodiment of the utility model, and is not any formal or substantial limitation of the utility model. It should be pointed out that ordinary technicians in this technical field can make some improvements and supplements without departing from the utility model, and these improvements and supplements should also be regarded as the protection scope of the utility model. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the spirit and scope of the utility model, which are all equivalent embodiments of the utility model; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the essential technology of the utility model are still within the scope of the technical solution of the utility model.
