Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to an external wall panel installation structure. Background Art

[0002] In the existing installation structure of external wall panels, for example, a technical solution with a patent application number of 201920164469.7 and a name of "an external wall panel installation structure" is disclosed in a Chinese patent document. This solution mainly includes a keel, a metal hanging piece, a Jinbang board, screws, and a metal gasket with a strip-shaped groove. Among them, the metal hanging piece is fixed on the keel through screws, the metal gasket is inserted between the metal hanging piece and the keel, and the strip-shaped groove of the metal gasket is sleeved on the screw. The Jinbang board is fixed on the metal hanging piece by hanging. By setting the metal gasket with a strip-shaped groove, this solution can achieve the purpose of padding or removing the gasket between the metal hanging piece and the keel by means of plugging or extraction without removing the screws, so that the distance between the metal hanging piece and the keel can be adjusted very quickly, so that the metal hanging piece is located at the correct installation position, and after each Jinbang board is installed, the outer surfaces of each Jinbang board are flush with each other, which is very convenient and fast. However, in the actual installation process, the metal gasket of this solution still has the following deficiencies: Since the strip-shaped groove is an open groove structure that penetrates the bottom surface and the front and rear surfaces of the metal gasket, and there is no limiting structure on the metal gasket to prevent it from swinging left and right, when inserting the metal gasket and tightening the screws, it is necessary to hold the metal gasket by hand. Otherwise, the metal gasket is likely to rotate and fall by itself with the screw as the rotation axis, resulting in the installer having to pick it up and reinstall and clamp it again, making its installation not yet convenient, fast and reliable enough. Therefore, in view of the foregoing deficiencies of the foregoing external wall panel installation structure, it is very necessary to further improve its structure in order to better meet the application needs of people. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the above problems and deficiencies, and provide an external wall panel installation structure. By respectively arranging limiting arms on the left and right sides of the metal gasket, this external wall panel installation structure can play a role in limiting the installation position of the metal gasket. There is no need to hold the metal gasket by hand, and it will not rotate and fall by itself, achieving the purpose of being installed in place with one plug-in, greatly improving the convenience and reliability of installation. Moreover, the two limiting arms and the metal gasket are of an integral structure, so it has very good connection structural strength and will not become loose, which can further ensure that the metal gasket will not rotate by itself, and the reliability is very high.

[0004] The technical solution of the present utility model is realized as follows: An exterior wall panel installation structure includes a keel, a metal hanging piece fixed on the keel by screws, a metal gasket disposed between the metal hanging piece and the keel, and an exterior wall panel body fixed on the metal hanging piece.

[0019] As Figure 1 shown in Figure 2 a kind of exterior wall panel installation structure described in the present utility model includes a keel 1, a metal hanging piece 3 fixed on the keel 1 by screws 2, a metal gasket 4 arranged between the metal hanging piece 3 and the keel 1, and an exterior wall panel body 5 fixed on the metal hanging piece 3. The metal gasket 4 is provided with a strip-shaped groove 41 penetrating through its bottom surface, front and rear surfaces and sleeved on the screw 2. In order to achieve the purpose proposed by the present utility model, as Figure 4 shown in

[0020] at both left and right sides of the metal gasket 4 are respectively provided with limiting arms 42 integrally bent backward, and the two limiting arms 42 are respectively arranged at both left and right sides of the keel 1. By respectively arranging the limiting arms 42 at both left and right sides of the metal gasket 4, the installation position of the metal gasket 4 can be limited. Without holding the metal gasket 4 by hand, it will not rotate and fall by itself, achieving the purpose of being installed in place with one-time insertion, greatly improving the convenience and reliability of installation. And the two limiting arms 42 and the metal gasket 4 are of an integral structure, so it has very good connection structural strength and will not become loose, further ensuring that the metal gasket 4 will not rotate by itself and the reliability is very high. Figure 1 During the actual application process, as

[0021] shown in Figure 4As shown, at the ends of the two limiting arms 42 away from the metal gasket 4, there are respectively provided first guiding inclined piece parts 421 which are integrally bent outward. In this way, the two first guiding inclined piece parts 421 can jointly form a flared structure, so that the two limiting arms 42 can be more easily placed on the left and right sides of the keel 1, greatly improving the convenience of installing the metal gasket 4.

[0022] When the thickness of the metal gasket 4 is insufficient, such as Figure 3 As shown, the present utility model further includes at least one inner gasket 6. The inner gasket 6 is also provided with a strip-shaped groove 41 penetrating its bottom surface and front and rear surfaces. An insertion gap 10 is also formed by enclosing the keel 1, the metal gasket 4 and the two limiting arms 42. The inner gasket 6 is inserted into the insertion gap 10, and the strip-shaped groove 41 of the inner gasket 6 is sleeved on the screw 2. By providing a plurality of inner gaskets 6, the number of inner gaskets 6 can be increased or decreased according to requirements to achieve the purpose of adjusting the thickness of the metal gasket 4. It is very flexible in use and adapts to various different distances between the metal hanging piece 3 and the keel 1, so that the metal hanging piece 3 can be quickly adjusted to the correct installation position. When the thickness of the metal gasket 4 is not enough to fill the distance between the metal hanging piece 3 and the keel 1, by pulling the metal gasket 4 forward, an insertion gap 10 can be formed between the metal gasket 4 and the keel 1. And by providing the insertion gap 10, after the inner gasket 6 is inserted into the insertion gap 10, the two limiting arms 42 can also play a role in limiting the installation position of the inner gasket 6, so that the inner gasket 6 will not rotate and fall off by itself, which is very reliable. Moreover, when multiple inner gaskets 6 need to be stacked, there is no need to take out the whole stack. According to requirements, the inner gaskets 6 can be inserted into the insertion gap 10 one by one respectively, and there is no need to additionally increase positioning tools such as positioning pins, and the installation and adjustment are more convenient.

[0023] In order to make the inner gasket 6 more easily inserted into the insertion gap 10, such as Figure 4 As shown, the top end of the metal gasket 4 is further provided with a second guiding inclined piece part 43 which is integrally bent forward. Through the integral structure design, the connection structure strength can be better.

[0024] When reducing the number of inserted inner gaskets 6, in order to make it convenient to take out the inner gasket 6 after insertion, such as Figure 5 As shown, the top end of the inner gasket 6 is further provided with a lifting part 61 which extends upward integrally, and the top surface of the lifting part 61 is higher than the top surface of the metal gasket 4. In this way, the lifting part 61 can protrude from the top surface of the metal gasket 4, which is convenient for taking out the inner gasket 6. Specifically, the top surface of the lifting part 61 is higher than the top surface of the second guiding inclined piece part 43.

[0025] In order to make it more convenient to take out the inner gasket 6, such as Figure 5 As shown, the lifting part 61 is further provided with a buckling groove 611. In this way, the convenience of taking can be improved.

[0026] In order to make the strip groove 41 more easily sleeved on the screw 2, as Figure 4 shown in Figure 5 the figure, the bottom ends of the strip grooves 41 of the metal gasket 4 and the inner gasket 6 are both trumpet-shaped guiding opening structures 411.

[0027] As Figure 1 shown in the figure, the bottom ends of the metal gasket 4 and the inner gasket 6 are respectively provided with conical insertion parts 44. Through the arrangement of the conical insertion parts 44, the metal gasket 4 can be more easily inserted between the metal pendant 3 and the keel 1, and the inner gasket 6 can also be more easily inserted into the insertion gap 10, so as to improve the convenience of installation. Specifically, the bottom ends of the strip grooves 41 of the metal gasket 4 and the inner gasket 6 extend to the bottom surfaces of the conical insertion parts 44.

[0028] In order to make the inner gasket 6 more easily inserted into the insertion gap 10, as Figure 5 shown in the figure, the left and right sides of the bottom end of the inner gasket 6 are respectively provided with guiding inclined surfaces 62. Specifically, the guiding inclined surfaces 62 extend to the conical insertion parts 44 of the inner gasket 6.

[0029] In the actual application process, the thicknesses of the metal gasket 4 and the inner gasket 6 are preferably both 1 mm for convenient adjustment.

[0030] In the actual application process, the inner gasket 6 is made of a metal material, so that it is not easy to age during long-term use. Specifically, the metal gasket 4 and the inner gasket 6 can be made of metal materials such as galvanized steel sheets.
