Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Example 1: referring to fig. 1, a profile for internal corner connection of wall panels comprises a first connecting structure and a second connecting structure. The first connection structure includes a fixing unit 100 and a fitting unit 200. The fixing unit 100 is made of a metal material (e.g., aluminum alloy) by extrusion molding, and includes a fixing plate 110 and an insertion groove 120 having a notch perpendicular to the fixing plate 110. The matching unit 200 is made of a metal material (e.g., an aluminum alloy) by extrusion molding, and includes a matching plate 210 and an inserting portion 220 vertically disposed on one plate surface of the matching plate 210, where the inserting portion 220 may be an integral inserting block or a pair of inserting pieces as in this embodiment. During assembly, the insertion part 220 is inserted into the insertion groove 120 and is in clearance fit with the insertion groove 120, that is, the groove width of the insertion groove 120 is larger than the thickness of the insertion part 220, specifically, the fit clearance between the insertion groove 120 and the insertion part 220 is 0.2-0.5 mm, for example, 0.3 mm.

After assembly, the fixing unit 100 and the fitting unit 200 form a first installation space, that is, a first installation space for inserting and installing the first wall panel 500 is formed among the fixing plate 110, the assembled inserting groove 120, the inserting portion 220 and the fitting plate 210. Fig. 1 shows an installation situation when the thickness of the first wall panel 500 is too large. As can be seen from the figure, when the thickness of the first wall panel 500 is larger, the insertion part 210 can deflect in the insertion groove 110 due to the clearance fit between the insertion groove 120 and the insertion part 220, and the matching plate 210 deflects at the same time, and after the deflection, the installation opening of the first installation space between the fixing plate 110 and the matching plate 210 is enlarged, so that the installation of the first wall panel 500 with larger thickness can be adapted.

The depth of the insertion part 220 inserted into the insertion groove 110 is (0.6-0.8): 1, for example, 0.7:1, with respect to the distance between the fixed plate 110 and the mating plate 210 after parallel assembly. Through the control of the above proportion, not only can the effective deflection adjustment amount between the matching unit 200 and the fixing unit 100 be ensured, but also the plugging portion 220 is ensured not to be easily separated from the plugging slot 110, which is beneficial to the firmness of assembly. In this embodiment, one side of the fixing plate 110 is vertically bent to form a transition section, and the inserting groove 120 is integrally formed on the transition section, so that the above ratio can be controlled by controlling the length of the transition section. In other embodiments, the insertion groove 120 may be directly integrally formed on one side edge of the fixing plate 110, so as to control the above ratio by controlling the insertion depth of the insertion part 220 (the length of the insertion part 220).

The second connecting structure is fixedly disposed on the other plate surface of the mating plate 210 opposite to the inserting portion 220, and includes a positioning plug-in 300 disposed perpendicular to the mating plate 210, and a first female corner piece 410 engaged with the positioning plug-in 300 to form a second mounting space. The positioning insert 300 and the first female corner piece 410 may be formed by integral molding. In this embodiment, the positioning insert 300 is an insertion strip having two side surfaces with anti-reverse teeth, and is assembled with the second wall panel 600 by inserting the insertion strip into the female tenon structure of the second wall panel 600 and inserting the half-female tenon piece of the second wall panel 600 into the second installation space formed by the positioning insert 400 and the first female angle piece 410. At the same time, the fitting plate 210 extends from the first female tab 410 to form a second female tab 420.

Example 2: embodiment 2 differs from embodiment 1 in that, referring to fig. 2, the insertion groove 120 includes an outer vertical plate 121, an inner vertical plate 122, and a groove bottom 123, the outer vertical plate 121 is disposed perpendicular to the fixing plate 120, and the inner vertical plate 122 is disposed obliquely with respect to the outer vertical plate 121 to form the insertion groove 120 in a flared shape.

Preferably, the wall of the insertion groove 120 and the surface of the insertion part 220 have a non-return structure. The non-return structure may be any one of the prior art, such as a non-return tooth.

The fixing unit 100 further includes a thickness adjusting piece 130 perpendicular to the fixing plate 110, and the thickness adjusting piece 130 is provided with a cutting notch 131. Accordingly, a constructor can break the thickness-adjusting piece 130 of a partial width at a construction site with a simple tool to adapt to the installation of the first wall panel 500 of at least two thickness specifications.

When the two transitional walls are not perpendicular to each other, the inserting part 210 can deflect in the inserting groove 110 due to the clearance fit between the inserting groove 120 and the inserting part 220, and the matching board 210 deflects at the same time, after deflection, the size of the installation opening of the first installation space between the fixing board 110 and the matching board 210 is kept unchanged, but the matching board 210 is inclined relative to the fixing board 110, so that the perpendicular relationship between the first installation space and the second installation space formed by the positioning plug-in unit 300 and the first female angle piece 410 is changed.

Fig. 3 shows the installation situation when the angle between two transition walls is less than 90 deg.. As can be seen from the figure, the inserting portion 210 is deflected toward the fixing plate 110 in the inserting groove 110, so that the angle between the first installation space and the second installation space formed by the positioning insert 300 and the first female angle piece 410 is smaller than 90 °, and the included angle between the first wall board 500 and the second wall board 600 after installation is also smaller than 90 °. In particular, since the inner vertical plate 122 is disposed obliquely relative to the outer vertical plate 121, in this case, the inserting portion 220 is always in overlapped contact with the inner sidewall of the inner vertical plate 122, and the inserting portion 220 is effectively prevented from being disengaged from the inserting groove 120 by the anti-reverse structure. This case also applies to the case when the thickness of the first wall panel 500 is thin.

The installation process of the sectional materials for connecting the internal corners of the wall boards in the embodiment 1 and the embodiment 2 comprises the following steps:

(1) completing the fixed installation of the first wall panel 500;

(2) fixing the fixing unit 100 to the first wall surface by a screw member or an adhesive;

(3) inserting the inserting part 220 into the inserting groove 120, and adjusting the setting angle of the fitting unit 200 according to the thickness of the first wall panel 500 or the actual angle between the first wall surface and the second wall surface;

(4) the female tenon structure of the second wall panel 600 is inserted into the positioning insert 300, and the fixed installation of the second wall panel 600 is completed.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
