[0002] In the prior art, the vertical exposed frame thermal insulation aluminum alloy curtain wall includes aluminum alloy column profiles for the exterior wall and the interior wall, which clamp and fix the ends of the glass curtain wall and are connected by an insulation strip to play an insulation role and reduce the amount of heat transferred from the exterior wall to the interior wall.

[0003] The insulation strip is usually made of nylon, which has good insulation effect but relatively poor strength. Considering this, the prior art often adds a small amount of hard connectors between the columns of the exterior wall and the interior wall to increase the connection strength. Figure 3 As shown in the figure, the screws are penetrated from the outside to the inside, and the spacing is generally about 300mm. However, it is obvious that both ends of the screws are in direct contact with the aluminum alloy profile, which is not conducive to heat insulation. Utility Model Content

The first thermally broken bridge 21 and the second thermally broken bridge 31 are respectively provided with a slot structure, and fishtail structures cooperating with the slot structure are respectively provided at both ends of the thermal insulation strip 1.

[0007] Furthermore, the thermal insulation strip 1 is I-shaped, and the supporting frame 11 extends to both ends into the slot structures of the first thermally broken bridge 21 and the second thermally broken bridge 31, and the ends of the supporting frame 11 located in the slot structure extend out the outer eaves 111 to both sides, and the width of the outer eaves 111 on both sides is greater than or equal to the width of the slot structure.

[0008] Furthermore, two sides of the heat insulation layer 12 bulge outwards.

[0009] Furthermore, the support frame 11 is an integral structure along the length direction of the thermal insulation strip 1 .

[0010] Furthermore, the support frame 11 is arranged in multiple sections at intervals along the length direction of the thermal insulation strip 1, each section has a thickness of 5 mm to 20 mm, and the interval distance is 200 mm to 400 mm.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As attached Figure 1-2 As shown, a vertical exposed frame thermal insulation aluminum alloy curtain wall column insulation strip structure includes an aluminum alloy exterior wall profile 2 and an aluminum alloy interior wall profile 3. At least one insulation strip 1 is arranged between the aluminum alloy exterior wall profile 2 and the aluminum alloy interior wall profile 3. The two ends of the insulation strip 1 are respectively connected to the aluminum alloy exterior wall profile 2 and the aluminum alloy interior wall profile 3. The insulation strip 1 includes an internal supporting frame 11, and the supporting frame 11 is covered with an insulation layer 12 on its surrounding side.

[0021] The aluminum alloy exterior wall profile 2 and the aluminum alloy interior wall profile 3 are respectively located on the exterior wall and interior wall of the building. Insulation strips are provided to reduce the heat transfer from the exterior wall to the interior wall. One end of the glass wall panel is clamped and fixed on both sides.

[0022] Compared with the prior art, the utility model has a heat insulation strip 1 internally coated with a support frame 11, which improves the strength of the heat insulation strip 1 itself, increases its bearing capacity, and prolongs its service life, while replacing the heat insulation strip 1 of the prior art. Figure 3 The profiles shown are reinforced by bolt connections.

[0023] Furthermore, the aluminum alloy exterior wall profile 2 is fixedly connected to the first thermally broken bridge 21, and the aluminum alloy interior wall profile 3 is fixedly connected to the second thermally broken bridge 31. The first thermally broken bridge 21 and the second thermally broken bridge 31 are arranged opposite to each other. The first thermally broken bridge 21 and the second thermally broken bridge 31 are respectively provided with a slot structure, and fishtail structures that cooperate with the slot structure are respectively provided at both ends of the thermal insulation strip 1. The end of the thermal insulation strip 1 is fixedly connected with the slot structure. This structure belongs to the prior art.

[0024] Furthermore, the heat insulation strip 1 is I-shaped, and the support frame 11 extends to both ends into the slot structures of the first broken bridge 21 and the second broken bridge 31, and the ends of the support frame 11 located in the slot structure extend outwardly to the outer edges 111 on both sides, and the width of the outer edges 111 on both sides is greater than or equal to the width of the slot structure. The support frame 11 is combined with the outer edge 111 structure, preferably forming Figure 2The I-shaped structure shown in the figure; when the width of the outer eaves 111 is greater than or equal to the width of the slot structure, it can play a better anti-slip effect, so that it can better replace the penetrating bolts and play a pulling effect between the profiles. Preferably, the outer eaves 111 has a trapezoidal structure, and the shorter upper side of the trapezoid is fixed to the end of the supporting frame 11, so that it can better cooperate with the insulation layer 12 to form a fishtail structure. The thickness of the insulation layer 12 on the side of the outer eaves 111 should be as uniform as possible to ensure that the difference between the maximum and minimum thicknesses is less than 5 mm.

[0025] Furthermore, the heat insulation layer 12 may be protruded outward on both sides, which may be wedge-shaped protrusions, preferably arc-shaped bulging protrusions as shown in the figure, to compensate the heat insulation performance as much as possible.

[0026] In terms of material selection, the thermal insulation layer 12 is preferably made of PA66GF25, i.e. polyamide 66+25 glass fiber, which is essentially no less than 65% polyamide 66 and 25%±2.5% glass fiber, and is the most commonly used thermal insulation strip material in the prior art.

[0027] The material of the supporting frame 11 is preferably aluminum alloy; the tensile strength of PA66GF25 is about 80MPa and the elastic modulus is about 4500N / mm; the tensile strength of aluminum alloy is about 160MPa and the elastic modulus is about 70000N / mm.

[0028] Aluminum alloy obviously has better mechanical properties. Of course, it is undeniable that using aluminum alloy as the inner support frame 11 will affect the overall thermal insulation performance of the thermal insulation strip 1 to a certain extent. Therefore, two solutions are proposed below:

[0029] 1. The support frame 11 is an integral structure along the length direction of the insulation strip 1; the length direction refers to the direction perpendicular to the structure in the figure. The advantage of this solution is that it is easier to manufacture, the integrally formed I-shaped aluminum profile, and the external composite insulation material, but the disadvantage is that the insulation performance is relatively poor;

[0030] 2. The support frame 11 is arranged in multiple sections along the length direction of the insulation strip 1, each section is 5mm~20mm thick, and the spacing is 200mm~400mm, corresponding to a substitute for the penetrating screws in the prior art; the advantage of this solution is that it has little effect on the insulation performance of the insulation strip 1, and the disadvantage is that the production cost is relatively high.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
