For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1 and 2 The figure shows an injection mortar enhanced exterior wall insulation system, comprising a wall 1, an insulation board 3 and anchor bolts 5, wherein bonding mortar 2 is provided between the wall 1 and the insulation board 3. A plastering mortar 4 is provided on the side of the insulation board 3 away from the wall 1. A mesh cloth 7 is provided inside the plastering mortar 4.

[0024] A first mounting hole 9 is formed through the insulation board 3, and a second mounting hole 10 is formed on the wall 1 near the insulation board 3. The second mounting hole 10 is coaxially arranged with the first mounting hole 9. The head of the anchor bolt 5 passes through the first mounting hole 9 and extends into the second mounting hole 10, and the tail of the anchor bolt 5 is left outside the plastering mortar 4.

[0025] Reinforced mortar 8 is filled between the anchor bolt 5 and the second mounting hole 10, and between the anchor bolt 5 and the first mounting hole 9. By filling the gap between the anchor bolt 5 and the second mounting hole 10, and between the anchor bolt 5 and the first mounting hole 9 with reinforced mortar 8, the bonding force and firmness can be improved, and the generation of cold and hot bridges can be prevented, thereby improving the insulation effect of the entire external wall insulation system. In addition, the reinforced mortar can also enhance the compressive performance of the entire external wall insulation system.

[0026] In a preferred embodiment, the anchor bolt 5 is an expansion anchor bolt, including an expansion sleeve and a bolt, and the surface of the bolt is provided with a plurality of longitudinal protrusions for increasing the contact area between the anchor bolt 5 and the reinforcing mortar 8 and increasing the friction. In order to further improve the firmness, the reinforcing mortar 8 is filled in the expansion sleeve of the anchor bolt 5. The reinforcing mortar 8 is preferably filled in the head of the expansion sleeve. When the bolt is screwed into the expansion sleeve, the force bearing area of ​​the anchor bolt can be expanded to the head of the expansion sleeve, thereby increasing the friction between the anchor bolt and the wall 1, and forming a more compact connection between the anchor bolt and the wall 1. The reinforcing mortar 8 can also be filled in the middle of the expansion sleeve.

[0027] In a preferred embodiment, a gap is left between the head of the anchor bolt 5 and the bottom of the second mounting hole 10, and the gap is filled with reinforcing mortar 8. This practice can increase the bonding area of ​​the reinforcing mortar 8 and improve the bonding force and shear strength between the anchor bolt 5 and the wall 1.

[0028] The first mounting hole 9 and the second mounting hole 10 are provided with a sleeve 6, and the sleeve 6 is arranged to fit the side wall of the first mounting hole 9 and the side wall of the second mounting hole 10, and the anchor 5 and the sleeve 6 are filled with reinforcing mortar 8. By providing the sleeve 6, a heat insulation layer can be formed between the wall 1 and the anchor 5, and between the insulation board 3 and the anchor 5, so as to reduce the occurrence of the thermal bridge effect, and help to improve the overall insulation effect of the external wall insulation system. Secondly, the provision of the sleeve 6 can increase the bonding area between the anchor 5 and the wall 1, thereby improving the firmness of the anchoring, and enhancing the stability and reliability of the external wall insulation system. In addition, the sleeve 6 can effectively avoid the leakage of the reinforcing mortar 8 around the anchor 5, ensure the uniformity and integrity of the reinforcing mortar 8 filling, and improve the bonding quality between the wall 1 and the anchor 5. In a preferred embodiment, the sleeve 6 is a stainless steel sleeve, and more preferably a 316 stainless steel sleeve.

[0029] The construction method of the above-mentioned injection mortar enhanced exterior wall insulation system is:

[0030] 1. First, a first mounting hole 9 is opened through the insulation board 3, and a second mounting hole 10 is opened on the side of the wall 1 close to the insulation board 3, and the first mounting hole 9 and the second mounting hole 10 are cleaned;

[0031] 2. Push the sleeve 6 into the first mounting hole 9 and the second mounting hole 10. Figure 3 As shown, the reinforcing mortar 8 is injected into the first mounting hole 9 and the second mounting hole 10 by using a syringe; the reinforcing mortar 8 is injected into the expansion sleeve of the anchor bolt 5 by using a syringe;

[0032] 3. Insert the expansion sleeve of the anchor bolt 5 into the first mounting hole 9 and the second mounting hole 10, and squeeze out the excess reinforcing mortar 8;

[0033] 4. Screw the bolt of the anchor bolt 5 into the expansion sleeve to squeeze out the reinforcing mortar 8 in the expansion sleeve, and form a dense mortar protective layer after solidification.

[0034] The above embodiments are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention.
