Specific embodiments

[0037] Please refer to Figure 1 , is a schematic cross-sectional structure diagram of a metal curtain wall sandwich panel conversion profile provided by an embodiment of the present invention, wherein the conversion profile 1 includes a first profile 10, a second profile 20 and a thermal insulation strip 30.

[0038] In which, the first profile 10 and the second profile 20 are respectively connected to the two ends of the thermal insulation strip 30; the thermal insulation strip 30, the first profile 10 and the second profile 20 have a flush bearing surface 40, the first profile 10 is provided with a first protrusion 101 on the side facing away from the bearing surface 40, and the second profile 20 is provided with a second protrusion 201 on the side facing away from the bearing surface 40, and a receiving groove 50 is formed between the first protrusion 101 and the second protrusion 201.

[0039] Specifically, the thermal insulation strip 30 is arranged between the first profile 10 and the second profile 20, and the bottom surfaces of the three are flush and constitute the bearing surface 40. The bearing surface 40 here is generally used to bear the lower plate of the metal curtain wall sandwich panel. The first profile 10 and the second profile 20 respectively have the first protrusion 101 and the second protrusion 201, and the first protrusion 101 and the second protrusion 201 are both arranged on the side of their respective profiles away from the bearing surface 40. The accommodating groove 50 is formed between the two protrusions. The accommodating groove 50 here is used to accommodate the upper plate of the metal curtain wall sandwich panel.

[0040] In addition, the embodiment of the present invention also provides a connection node structure of the metal curtain wall sandwich panel conversion profile, such as Figure 2As shown in the figure, it is a three-dimensional structure schematic diagram of a connection node structure of a metal curtain wall sandwich panel conversion profile provided by an embodiment of the present invention. In order to make the description clearer and more detailed, the conversion profile 1 will be described here in combination with its connection node structure.

[0041] The connection node structure of the metal curtain wall sandwich panel conversion profile includes the conversion profile 1, the keel 2, the first plate 3 and the second plate 4.

[0042] Among them, the conversion profile 1 is connected to the keel 2. For the specific structure of the conversion profile 1, please refer to the description of the above embodiments.

[0043] The first plate 3 is arranged below the bearing surface 40 and is connected to the keel 2;

[0044] The second plate 4 is arranged above the conversion profile 1, and a third protrusion 401 is provided at the end facing the first plate 3, and the third protrusion 401 is received in the receiving groove 50.

[0045] Specifically, the first plate 3 is generally a detachable metal curtain wall sandwich panel, and the second plate 4 is generally a non-detachable rock wool sandwich panel. The keel 2 is generally a vertical keel of the metal curtain wall. During construction, the first plate 3 is first fixed to the keel 2 using connectors, and then the conversion profile 1 is placed on the top of the first plate 3 and fixed to the keel 2 using connectors. So that the bearing surface 40 bears on the top end face of the first plate 3. Finally, the second plate 4 is connected above the conversion profile 1. Since the end of the second profile 2 facing the first plate 3 is provided with the third protrusion 41, and the opening of the receiving groove 50 formed by the first protrusion 101 and the second protrusion 201 faces away from the first plate 3, the third protrusion 401 is just received in the receiving groove 50, thereby fixing the second plate 4, thus connecting the first plate 3 and the second plate 4 together and connecting them to the keel 2. When it is necessary to remove and replace the first plate 3 below, it is not necessary to remove the second plate 4 above, and the second plate 4 below can be directly removed, so that the construction of the plates can be reversed, improving the construction progress and ensuring the building quality.

[0046] The heat insulation strip 30 here has good characteristics of breaking the "thermal bridge", avoiding the occurrence of thermal bridge phenomenon at the joint of the curtain wall structure, and improving the heat insulation performance of the metal curtain wall.

[0047] Furthermore, please refer to Figures 3-4 , two heat insulation strips 30 are connected between the first profile 10 and the second profile 20, and a first distance D1 is separated between the two heat insulation strips 30.

[0048] Specifically, in the connection node structure of the conversion profile 1, a connector 11 is provided within the first spacing D1 to connect the first profile 10 and the second profile 20 to the keel 2. Specifically, the connector 11 sequentially passes through the second profile 20, the first spacing D1, and the first profile 10 to connect to the keel 2. Here, the first spacing D1 provides clearance for the connector 11 of the conversion profile 1, preventing damage to the insulation strip 30 during installation, thereby ensuring the insulation strip 30's "cold-hot bridge" characteristics. The connector 11 herein includes, but is not limited to, self-tapping screws and other connectors.

[0049] In addition, in other preferred embodiments of the present invention, the thermal insulation strip 30 is made of PA66 engineering plastic.

[0050] Specifically, the thermal insulation strip 30 is made of the PA66 engineering plastic. The PA66 engineering plastic here has the advantages of reducing heat conduction, preventing condensation, heat preservation and energy saving, being beneficial to health, reducing noise, and enhancing water tightness, air tightness, and wind pressure resistance, thereby improving the quality of the metal curtain wall.

[0051] Furthermore, in order to improve the tightness and reliability of the connection between the conversion profile 1 and the second plate 4 and the keel 2 , the first protrusion 101 is flush with the side of the first profile 10 facing away from the insulation strip 30 .

[0052] In addition, in other preferred embodiments of the present invention, a bend 102 is provided on the top of the first protrusion 101 toward the thermal insulation strip 30 .

[0053] Here, the first protrusion 101 has an inner hook structure toward the center of the conversion profile 1, which is specifically manifested as the bend 102 at the top of the first protrusion 101. When in use, the corresponding position of the second plate 4 is provided with a groove (not shown in the figure) for accommodating the bend 102, thereby improving the reliability of the connection between the two.

[0054] Furthermore, a recessed portion 31 is provided on a side of the end of the first plate 3 facing the second plate 4 away from the keel 2 , and a connecting piece 11 is provided in the recessed portion 31 for connecting the first plate 3 to the keel 2 .

[0055] Specifically, a step is provided on the outer side of the top of the first plate 3 , namely the recessed portion 31 . The recessed portion 31 is used to set the connecting member 11 to fix the first plate 3 to the keel 2 .

[0056] In addition, the second projection 201 is spaced apart from the side of the second profile 20 facing away from the heat insulation strip 30 by a second distance D2.

[0057] Specifically, the second projection 201 is not flush with the outer surface of the second profile 20, but is separated from the outer surface of the second profile 20 by the second distance D2.

[0058] Furthermore, a fourth projection 402 is provided at the end of the second plate 4 facing the first plate 3. The fourth projection 402 is provided above the recess 301, and the bottom of the fourth projection 402 is flush with the bearing surface 40.

[0059] Specifically, the fourth projection 402 is located outside the bottom of the second plate 4, and its thickness matches the second distance D2. That is, the fourth projection 402 and the third projection 401 form a groove, and the second projection 201 is just inserted into this groove.

[0060] In addition, the side of the second profile 20 facing away from the bearing surface 40 extends a distance away from the heat insulation strip 30 and then is connected to the top of the second projection 201 to form an inclined surface 202.

[0061] Specifically, the bottom of the inclined surface 202 is connected after the second projection 201 extends a distance outward, and the top of the inclined surface 202 is connected to the top of the second projection 201. Here, the inclined surface 202 has the function of facilitating the quick insertion of the second plate 4 into the receiving groove 50 to form a quick connection.

[0062] Even further, connection projections 310 are provided at both ends of the heat insulation strip 30. The size of the connection projections 310 gradually decreases from the direction away from the center of the heat insulation strip 30 to the direction close to the center of the heat insulation strip 30;

[0063] Connection grooves 12 are provided at one ends of the first profile 10 and the second profile 20 close to each other. The shape of the connection grooves 12 matches the shape of the connection projections 310, and the connection grooves 12 are snap-connected to the connection projections 310.

[0064] Specifically, the connection grooves 12 have a structure with a large internal space and a small opening, while the connection projections 310 have a structure that gradually decreases from the direction away from the center of the heat insulation strip 30 to the direction close to the center of the heat insulation strip 30. The connection projections 310 are introduced into the connection grooves 12 from the side of the connection grooves 12 to form a snap connection between the two. Through this connection relationship, both the reliability of the connection between the two can be ensured, and it is also convenient for disassembly, installation, and replacement, and the heat insulation strip 30 will not be damaged during the operation.

[0065] In addition, in other preferred embodiments of the present invention, a third profile 60 and a fourth profile 70 are connected to each other within the recessed portion 301. The third profile 60 is connected to the first plate 3 on the side facing away from the keel 2, and the fourth profile 70 is connected to the side of the third profile 60 away from the keel 2. The tops of both the third profile 60 and the fourth profile 70 are in contact with the bottom of the fourth protrusion 402.

[0066] Specifically, the third profile 60 and the fourth profile 70 disposed within the recessed portion 301 serve the functions of sealing and decoration. The third profile 60 is connected to the first plate 3 within the recessed portion 301 by means of connectors such as self-tapping screws. The fourth profile 70 is connected to the third profile 60, and both are in contact with the bottom of the fourth protrusion 402 of the second plate 4 above them. The side of the fourth profile 70 facing away from the third profile 60 is flush with the outer side surfaces of the second plate 4 and the first plate 3.

[0067] Furthermore, the third profile 60 is intermittently disposed along the length direction of the first plate 3, and a card slot 601 is provided on the side of the third profile 60 facing away from the keel 20.

[0068] The fourth profile 70 is continuously disposed along the length direction of the first plate 3, and an EPDM sealing strip 701 matching the shape of the card slot 601 is provided on the side of the fourth profile 70 facing the third profile 60.

[0069] Specifically, the cross-section of the third profile 60 is generally a C-shaped structure, and a C-shaped card slot 601 is provided on the side facing away from the keel 20. Here, the intermittent disposition of the third profile 60 along the length direction of the first plate 3 is mainly to avoid the connector 11 at the intermittent positions. The fourth profile 70 is usually continuously disposed along the length direction of the first plate 3, which can shield the recessed portion 301 to ensure its sealing performance and aesthetic appearance. By providing the EPDM sealing strip 701 on the side of the fourth profile 70 facing the third profile 60, and the EPDM sealing strip 701 can be inserted into the card slot 601 to form a connection with the third profile 60, thus further improving its sealing performance and enabling the metal curtain wall to have better heat insulation performance.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
