[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] This utility model provides, for example Figures 1 to 7 The composite building exterior wall shown includes a wall body 6. A protective assembly is provided on the surface of the wall body 6. The protective assembly includes an anti-corrosion layer 1, a first fixing hole 11, an anti-seepage layer 2, a second fixing hole 21, an insulation layer 3, a third fixing hole 33, reinforcing vertical bars 4, first horizontal bars 41, second horizontal bars 42, fourth fixing holes 43, and a fixing component 5. The reinforcing vertical bars 4, first horizontal bars 41, and second horizontal bars 42 are all fixed inside the insulation layer 3. The anti-seepage layer 2 is fixed to the surface of the insulation layer 3, and the anti-corrosion layer 1 is fixed to the surface of the anti-seepage layer 2. Multiple sets of first fixing holes 11 are provided on the surface of the anti-corrosion layer 1, multiple sets of second fixing holes 21 are provided on the surface of the anti-seepage layer 2, and multiple sets of third fixing holes 21 are provided on the surface of the insulation layer 3. The first crossbar 41 has three fixing holes 33. Multiple sets of fourth fixing holes 43 are opened on the surface of the first crossbar 41. The first fixing hole 11, the second fixing hole 21, the third fixing hole 33 and the fourth fixing hole 43 are connected from front to back. The fixing component 5 includes an expansion screw 51, a rubber pad 52, a locking nut 53 and a protective sleeve 54. The rear end of the expansion screw 51 is fixed inside the wall body 6. The front end of the expansion screw 51 passes through the first fixing hole 11, the second fixing hole 21, the third fixing hole 33 and the fourth fixing hole 43. The rubber pad 52 is sleeved on the surface of the expansion screw 51. The locking nut 53 is threadedly connected to the front end of the expansion screw 51. The protective sleeve 54 is sleeved on the front end of the expansion screw 51 and the surface of the locking nut 53.

[0036] Among them, the anti-corrosion layer 1 is made of fluorocarbon coated aluminum plate with a thickness of 1.5mm, the anti-seepage layer 2 is made of polymer waterproof membrane with a thickness of 2mm, the insulation layer 3 is made of graphite modified polystyrene foam board with a density of 30kg / m³, and the reinforcing vertical bar 4, the first horizontal bar 41 and the second horizontal bar 42 are integrally injection molded plastic plates.

[0037] During the production process, a frame consisting of reinforcing vertical bars 4, first horizontal bars 41, and second horizontal bars 42 is placed inside a mold. Then, graphite-modified polystyrene foam is filled into the mold, encasing the reinforcing vertical bars 4, first horizontal bars 41, and second horizontal bars 42 inside to form a whole. Next, adhesive is applied to the surface of the insulation layer 3, and then the waterproof membrane is bonded to the surface of the insulation layer 3. Then, adhesive is applied to the inside of the anti-corrosion layer 1, and the anti-corrosion layer 1 is bonded to the surface of the waterproof membrane. Finally, holes are punched in the surface using a drilling device. The protective components are modularized to facilitate transportation and installation, improving operational convenience.

[0038] During installation, the protective component is first attached tightly to the surface of the wall body 6, and the drilling device is used to drill holes through multiple sets of fixing holes on the surface of the wall body 6. Then, the expansion screw 51 is inserted through multiple sets of fixing holes and its rear end is fixed inside the wall body 6. Next, the rubber pad 52 is placed on the surface of the expansion screw 51, and then the locking nut 53 is threaded to the front end of the expansion screw 51. In this way, the protective component is fixed to the surface of the wall body 6, forming a multi-layer composite wall. The three-layer structure works together to effectively improve the corrosion resistance, waterproofing and thermal insulation performance of the original wall.

[0039] See Figure 5 and Figure 6 The first horizontal bar 41 and the second horizontal bar 42 are alternately fixed between multiple sets of reinforcing vertical bars 4.

The left side surface of the insulation layer 3 is fixedly connected with a plug block 32. The right side surface of the insulation layer 3 is provided with a plug groove 31. The plug block 32 in the right insulation layer 3 is plugged and fixed with the plug groove 31 in the left insulation layer 3. The left end of the right second horizontal bar 42 is plugged and fixed with the plug hole 44 in the left reinforcing vertical bar 4.

[0040] In addition, during the installation of the protective components, the protective components are installed from left to right. When installing the right protective component, the plug-in block 32 at the left end of the right insulation layer 3 is inserted into the plug-in groove 31 at the right end of the left insulation layer 3, and the left end of the right second horizontal bar 42 is inserted into the plug-in hole 44 on the surface of the left reinforcing vertical bar 4. The two sets of protective components are spliced ​​and fixed to improve the stability and structural strength of the connection between the two sets of protective components. The plug-in block 32 and the plug-in groove 31 cooperate to make the two sets of insulation layers 3 interlock with each other, reduce the splicing seam, and further improve the thermal insulation effect.

[0041] See Figure 1 and Figure 2 The left and right edges of the front surface of the anti-corrosion layer 1 are fixedly connected with snap-fit ​​plates 12, and the surfaces of the two sets of snap-fit ​​plates 12 that are close to each other in the two sets of anti-corrosion layers 1 are snapped with sealing strips 13.

[0042] Meanwhile, after the two sets of protective components are spliced ​​together, the snap-fit ​​plates 12 on the adjacent sides of the two sets of anti-corrosion layers 1 will abut together. At this time, the sealing strip 13 is snapped onto the surface of the two sets of snap-fit ​​plates 12 to cover the gap between the two sets of anti-corrosion layers 1, further improving the anti-corrosion effect and reducing rainwater infiltration.

[0043] The working principle of this utility model is as follows: By using the fixing component 5 to fix the anti-corrosion layer 1, the impermeable layer 2, and the thermal insulation layer 3 to the surface of the wall body 6, a composite exterior wall is formed, which effectively improves the anti-corrosion, impermeability, and thermal insulation performance of the building exterior wall, and is easy to install. It can be used for new building surfaces and renovation of old houses, thus improving its applicability. At the same time, by fixing the reinforcing vertical bar 4, the first horizontal bar 41, and the second horizontal bar 42 inside the thermal insulation layer 3, the structural strength of the thermal insulation layer 3 is effectively improved. During the splicing of the left and right sets of protective components, the plug block 32 is inserted into the plug groove 31, and the second horizontal bar 42 is inserted into the plug hole 44, which improves the stability of the connection between the two sets of protective components and the structural strength of the two sets of protective components. The sealing strip 13 is clipped onto the surface of the snap plate 12 to seal the gap between the two sets of anti-corrosion layers 1, further improving the anti-corrosion and impermeability of the protective components.
