[0002] In order to ensure that the indoor temperature does not lose in winter, people often place straw and other items on the outside of the wall, but in dry weather, fires are very likely to occur. With the development of society, the insulation materials installed outside the wall are also constantly evolving. Now the insulation materials are mostly composed of Yintong YT inorganic active wall, mesh cloth, inner wall glass fiber cotton and outer wall phenolic foam material. These insulation materials are installed on the outer wall of the wall through an exterior wall insulation structure.

[0003] A current exterior wall insulation structure usually plans the size of each exterior wall insulation integrated panel on the outer wall of the wall, marks fixing devices on the edges of these size lines, applies bonding mortar on the inner wall of the corresponding exterior wall insulation integrated panel, marks fixing grooves on the side walls around the exterior wall insulation integrated panel, inserts the fixing grooves into the fixing devices, sticks the inner wall of the exterior wall insulation integrated panel to the wall, inserts the fixing grooves above the exterior wall insulation integrated panel into the fixing devices above, the fixing grooves of the exterior wall insulation integrated panel in the middle share a fixing device, and finally uses insulation strips to seal the gaps between the exterior wall insulation integrated panels.

[0004] Although the current exterior wall insulation structure can fix the exterior wall insulation integrated panels to the wall, if some of the exterior wall insulation integrated panels are damaged, because the exterior wall insulation integrated panels inside share a fixing device, when disassembling, it is necessary to dismantle all the nearby integrated panels that share the fixing device and then replace them for secondary assembly. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the external wall insulation integrated plate of the existing external wall insulation structure cannot be freely replaced as a single body.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: an exterior wall insulation structure, including a wall body, a plurality of convex support blocks are arranged on the top of the wall body, and exterior wall insulation integrated panels corresponding to the rectangular frame formed by the convex support blocks are arranged between the convex support blocks, the gaps between the exterior wall insulation integrated panels are sealed by insulation strips, the exterior wall insulation integrated panels are connected to the convex support blocks by a detachable bolt fixing device, and the outer wall of the exterior wall insulation integrated panel is provided with a fixing groove for storing the detachable bolt fixing device.

[0007] As an improvement, the exterior wall thermal insulation integrated panel comprises an outer cladding layer, a thermal insulation layer and an adhesive layer arranged in sequence from the outside to the inside, and the fixing groove is located on the outer wall of the outer cladding layer.

[0008] As an improvement, the removable bolt fixing device includes an expansion sleeve and an expansion sleeve screw for fixing the expansion sleeve, the expansion sleeve is a single open expansion sleeve, the open end of the expansion sleeve is in the same direction as the expansion piece, the top end of the expansion piece of the expansion sleeve is provided with a fixing plate corresponding to the fixing groove, and the expansion sleeve screw passes through the closed end of the expansion sleeve and the top end surface of the protruding block of the convex support block.

[0009] As an improvement, the convex support block is connected to the wall through expansion screws, and the expansion screws pass through the low-position support blocks and the wall on both sides of the convex support block.

[0010] As an improvement, the outer wall of the wall and the inner wall of the adhesive layer are connected by bonding mortar.

[0011] As an improvement, the gaps between the exterior wall thermal insulation integrated panels and the thermal insulation strips are sealed by means of sealant.

[0012] The advantages of the utility model compared with the prior art are: the device fixes the external wall insulation integrated panel by the fixing piece of the detachable bolt fixing device, and the expansion sleeve tightly presses the external wall insulation integrated panel to avoid loosening by continuously screwing in the expansion sleeve screw. Because the fixing piece is located in the outer envelope, when disassembling the external wall insulation integrated panel, it is only necessary to remove the detachable bolt fixing device fixing the panel, and then the panel can be taken out and replaced. The nearby external wall insulation integrated panels are fixed by the limiting position of the convex support block and the position of the detachable bolt fixing devices on the other three sides of the panel, so that these panels will not fall off.
