[0041] As Figures 1-4 shown, the utility model discloses a kind of outer wall external thermal insulation system, including concrete outer wall body 100, insulation board 200 and anchor 300. Insulation board 200 uses thermal decoration integrated board 600, and is fixed on outer wall body 100, and there is plaster layer 400 and bonding mortar layer 500 between insulation board 200 and outer wall body 100, and the side of insulation board 200 deviating from outer wall body 100 is provided with first waterproof and anti-cracking reinforcing layer 600, carbon fiber mesh cloth (not shown) and second waterproof and anti-cracking reinforcing layer 700. Outer wall body 100, plaster layer 400, bonding mortar layer 500, insulation board 200, first waterproof and anti-cracking reinforcing layer 600 and second waterproof and anti-cracking reinforcing layer 700 are sequentially arranged from inside to outside. Carbon fiber mesh cloth is arranged in first waterproof and anti-cracking reinforcing layer 600, to enhance the anti-cracking performance. Anchor 300 is in-situ reinforcing combined anchor 300, for assisting fixed insulation board 200. It mainly includes expansion pipe 310, anchor disc 320, reinforcing pipe 330, expansion core 340 and reinforcing connecting piece 350 several partial structures.

[0042] Specifically, the expansion pipe 310 penetrates into the outer wall 100, the expansion pipe 310 is internally provided with an expansion pipe cavity 311, and the expansion pipe 310 is externally provided with expansion cracks 312 and structures such as barbs and inverted cones for improving the pullout resistance. The expansion cracks 312 penetrate the expansion pipe cavity 311 and are in a curve shape along the length direction of the expansion pipe 310.

[0043] The anchor disc 320 includes two parts of a main disc 321 and a reinforcing disc 322, and the main disc 321 and the reinforcing disc 322 are located on the side of the thermal insulation board 200 away from the outer wall 100. The main disc 321 is located in the first waterproof and anti-cracking reinforcing layer 600, the reinforcing disc 322 is located in the second waterproof and anti-cracking reinforcing layer 700, the diameter of the main disc 321 is larger than that of the reinforcing disc 322, and the stress dispersion capacity and the pullout resistance are better.

[0044] The main disc 321 and the reinforcing disc 322 are preferably arranged in parallel with each other, and a plurality of through holes are arranged through the main disc 321 and / or the reinforcing disc 322. The through holes are uniformly arranged along the circumferential direction of the main disc 321 and the reinforcing disc 322, can automatically form an effective fixing mechanism with the first waterproof and anti-cracking reinforcing layer 600 and the second waterproof and anti-cracking reinforcing layer 700, and enhance the fixing effect. Similarly, a plurality of strip-shaped grooves 321b are arranged on the side of the main disc 321 away from the expansion pipe 310, the length direction of the strip-shaped grooves 321b is consistent with the radial direction of the main disc 321, and the pullout resistance of the anchor 300 can be improved. Figure 5 、 6 As shown in the drawings, in the embodiment, the through holes, i.e., the first through holes 321a and the second through holes 322a, are arranged on the main disc 321 and the reinforcing disc 322. The first through holes 321a are spaced apart by the strip-shaped grooves 321b on the main disc 321.

[0045] The reinforcing pipe 330 is internally provided with a reinforcing pipe cavity 331, and the reinforcing pipe cavity 331 penetrates through both ends. One end of the reinforcing pipe 330 is fixedly connected to the main disc 321, the main disc 321 is provided with a through hole matched with the reinforcing pipe cavity 331, and the other end of the reinforcing pipe 330 is fixedly connected to the expansion pipe 310, so as to connect the coaxially arranged reinforcing pipe cavity 331 and expansion pipe cavity 311.

[0046] The expansion core 340 penetrates through the main disc 321 and penetrates into the expansion pipe cavity 311, and then expands the expansion cracks 312, so that the expansion pipe 310 is deformed and generates an expansion force, and the expansion pipe 310 is tightly fixed on the outer wall 100. In order to increase the durability and stability of the connection and ensure the connection strength, the expansion core 340 is made of a metal material.

[0047] The reinforcing connecting piece 350 is in the same straight line with the central axis of the expansion core 340, and is fixedly connected to the reinforcing disc 322 at one end away from the expansion tube 310, and can be penetrated into the reinforcing tube cavity 331 at the other end. After being penetrated into the reinforcing tube cavity 331, the reinforcing connecting piece 350 can be fixedly connected in the reinforcing tube cavity 331 and fixedly connected with the reinforcing tube 330, so as to realize in-situ reinforcement, enhance the fixing effect of the anchoring piece 300, and improve the stability of anchoring. In the embodiment, the inner wall of the reinforcing tube cavity 331 and the outer wall of the reinforcing connecting piece 350 are provided with matching threads, and the two can be fixedly connected together through the threads.

[0048] Since the expansion core 340 and the reinforcing connecting piece 350 are separately arranged, the thermal bridge phenomenon affected by the anchoring piece 300 is relatively light. As preferred, the length of the reinforcing connecting piece 350 is shorter than the length of the reinforcing tube cavity 331, so that there is a gap between the expansion core 340 and the reinforcing connecting piece 350 while the expansion core 340 props open the expansion crack 312 and the reinforcing connecting piece 350 performs in-situ reinforcement, and the interval L between the two is about 8 mm. By means of the gap between the expansion core 340 and the reinforcing connecting piece 350, the thermal bridge can be blocked to avoid the thermal bridge phenomenon. Of course, the reinforcing connecting piece 350 made of non-metallic material can also be used for reinforcement to further weaken the thermal bridge effect.

[0049] Similarly, the expansion tube 310 and the reinforcing tube 330 can be integrally formed or separately arranged to reduce the thermal bridge effect. As shown in FIG. 4, when the expansion tube 310 and the reinforcing tube 330 are separately arranged, they can be connected together through the expansion core 340. Figures 7-13 As shown in FIG. 4, the expansion tube 310 and the reinforcing tube 330 are separately arranged and can be connected together through the expansion core 340. To facilitate the connection of the expansion tube 310 and the reinforcing tube 330, the expansion core 340 includes a thin rod part 341 and a thick head part 342, and the head part 342 is connected to one end of the rod part 341. Corresponding to the expansion core 340, the diameter of the expansion tube cavity 311 is matched with the thickness of the rod part 341, and the diameter of the reinforcing tube cavity 331 is matched with the size of the head part 342 and is slightly larger than that of the expansion tube cavity 311. The end of the reinforcing tube 330 is provided with a limiting hole 332, the limiting hole 332 is located between the expansion tube cavity 311 and the reinforcing tube cavity 331, and the expansion tube cavity 311 and the reinforcing tube cavity 331 can be connected to each other through the limiting hole 332. The limiting hole 332 is used for penetrating the rod part 341 of the expansion core 340 and intercepting the head part 342 of the expansion core 340, and can be used for connecting the expansion tube 310 and the reinforcing connecting piece 350 together with the expansion core 340.

[0050] In the embodiment, the expansion core 340 is a drill tail nail, has strong drilling capacity, and is more firmly connected to the expansion tube 310 after being locked into the expansion tube 310. The expansion tube 310 is a nylon tube, has good chemical corrosion resistance and insulation, and is beneficial to weakening and blocking the thermal bridge phenomenon.

[0051] In addition, when the expansion pipe 310 and the reinforcing pipe 330 are arranged separately and connected by the expansion core 340, the outer wall of the reinforcing pipe 330 is further provided with a clamping portion 333, the clamping portion 333 is formed along the axial direction of the expansion pipe 310 and surrounds the outer periphery of the expansion pipe 310, the clamping portion 333 can abut against the outer wall of the expansion pipe 310, which can assist in quickly docking the expansion pipe 310 and the reinforcing connector 350 during installation, and can strengthen the connection strength of the expansion pipe 310 and the reinforcing connector 350 after installation. As a preferred, the clamping portion 333 is arranged in a circular ring shape, which has a better effect.

[0052] As can be seen from the above, the insulation board 200 in the system has high anchoring strength and good stability, and the system thermal bridge phenomenon is lighter or even can be blocked.

[0053] Although the utility model is specifically shown and introduced in combination with the preferred embodiments, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all these changes are within the protection scope of the utility model.
