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, the top edge-closing profile for a wall panel includes a fixing seat 100 and an edge-closing member 200 that are inserted into each other, and particularly, the fixing seat 100 and the edge-closing member 200 are both metal alloy profiles (e.g., aluminum alloy).

The fixing base 100 includes a mounting plate 110, a clamping groove 120 with an opening facing to a plane perpendicular to the mounting plate 110 is formed on an upper portion of the mounting plate 110, and a fixing end clamping plate 130 is vertically extended from a lower portion of the mounting plate 110. The clamping groove 120 and the fixed end clamping plate 130 are positioned on the same side of the mounting plate 110. The edge fastener 200 includes an edge-receiving plate 210, and a latch 220 perpendicular to the plane of the edge-receiving plate 210 is disposed on the upper portion of the edge-receiving plate 210. During assembly, the clamping tenon 220 is inserted into the clamping groove 120, and the clamping tenon 220 is in clearance fit with the clamping groove 120.

Fig. 2 shows a state of the top edge-closing profile of the wall panel of the present embodiment completing the edge closing of the wall panel 300 with a larger thickness. Referring to fig. 2, first, the mounting plate 110 is screwed to the wall or the keel fixed to the wall by using self-tapping screws or wall nails through the mounting holes formed in the mounting plate 110, and the top surface of the catching groove 120 abuts against the ceiling surface; then, inserting the clamping tenon 220 into the clamping groove 120 to complete the pre-assembly of the fixing base 100 and the edge-fastening member 200, at this time, a clamping space for inserting and fixing the wall panel 300 is formed among the mounting plate 110, the clamping groove 120 and the edge-closing plate 210, an entrance of the clamping space is formed between the edge of the fixing end clamping plate 130 and the edge-closing plate 210, and the vertical distance between the two is the width of the entrance (i.e. the standard thickness of the mountable wall panel 300); finally, one end of the wall plate 300 is extended into the entrance of the clamping space from the entrance of the clamping space. At this time, since the thickness of the wall panel 300 is greater than the width of the entrance of the clamping space, as the wall panel 300 goes deeper into the clamping space, the clamping tenon 220 deflects in the clamping groove 120, and deflects the edge-receiving plate 210 relative to the mounting plate 110 (the two are no longer in parallel state), thereby expanding the opening and closing width of the entrance of the clamping space (i.e. the thickness of the mountable wall panel 300). When wallboard 300 deepens in the centre gripping space and blocks to joint tenon 220 and dies in joint groove 120 (promptly joint tenon 220 can't continue to take place to deflect in joint groove 120), wallboard 300 top edge supports with receiving the linearity of sideboard 210 and leans on, joint tenon 220 blocks in joint groove 120 and dies the cooperation and can be fixed in wallboard 300 in the centre gripping space to accomplish the receipts limit of wallboard 300 that thickness is bigger relatively and handle.

Preferably, the gap between the latch 220 and the latch groove 120 is 0.2-0.5 mm, for example, the gap between the latch 220 and the latch groove 120 may be 0.3mm or 0.4 mm.

Further preferably, referring to fig. 1, the engaging groove 120 is connected to the mounting plate 110 by the extension plate 140, a ratio of a vertical distance L between an edge of the fixed end holding plate 130 and a plane where the notch of the engaging groove 120 is located to a dimension of a groove depth D of the engaging groove 120 is (3-3.5): 2, and a length of the engaging tenon 220 is the same as a groove depth of the engaging groove 120. For example, in this embodiment, the clearance volume between joint tenon 220 and the joint groove 120 is 0.4mm, and the perpendicular distance L between the edge of stiff end grip block 130 to the plane at the notch place in joint groove 120 is 12mm, and the groove depth D in joint groove 120 is 8mm, and at this moment, the wallboard top of this embodiment is received the limit section bar and can be received the limit to the wallboard that thickness is 12 ~ 12.5mm and be handled.

By the arrangement of the extension plate 140 and the limitation of the dimension ratio of the vertical distance between the edge of the fixed end clamping plate 130 and the plane where the notch of the clamping groove 120 is located to the groove depth of the clamping groove 120, the dimension ratio of the tenon length of the clamping tenon 220 (or the tenon depth of the clamping groove 120) to the thickness of the wall plate 300 is substantially limited, so that the thickness ratio of the wall plate 300 can be as follows: the phenomenon that the deflectable amplitude of the clamping tenon 220 in the clamping groove 120 is too small due to too long tenon length of the clamping tenon 220 is avoided, so that the thickness deviation of the wallboard 300, which can be adapted by the wallboard top edge-folding sectional material, is too small, and the adaptability of the wallboard is relatively poor; and, avoid the tenon length of the joint tenon 220 to be too short, cause the deflectable range of the joint tenon 220 in the joint groove 120 to be too large, thus the joint tenon 220 is easy to deviate from the joint groove 120, and the stability of the joint assembly is reduced.

Preferably, the inner wall surfaces of the upper groove edge 121 and the lower groove edge 122 are provided with a non-return structure, and the upper surface and the lower surface of the latch 220 are provided with a non-return structure. In the present embodiment, the non-return structure is a protruding ridge structure. The retaining structures of the engaging groove 120 and the engaging tongue 220 can be engaged with each other to effectively prevent the engaging tongue 220 from slipping out of the engaging groove 120.

Further preferably, the fixed end holding plate 130 is provided with a pre-cut line 150. In this embodiment, the pre-cut lines 150 are a pair of scribe grooves symmetrically formed on the upper and lower surfaces of the fixed end holding plate 130, and the pre-cut lines 150 are formed to penetrate the longitudinal direction of the fixed end holding plate 130. So that a constructor can quickly disconnect the fixed end clamping plate 130 at the pre-shearing line 150 by using a simple apparatus (e.g., a pliers) according to the thickness of the wall panel 300 at a construction site, so that the vertical distance between the new edge formed by the fixed end clamping plate 130 and the edge closing plate 210 is larger than before, and the wall panel top edge closing profile of the present embodiment can be adapted to the installation of the wall panels 300 with two thicknesses.

Example 2: referring to fig. 3, embodiment 2 is different from embodiment 1 in that the catching groove 120 is a flared groove and the catching tenon 220 is a square tenon. Specifically, the catching groove 120 includes an upper groove edge 121, a lower groove edge 122, and a groove bottom 123, which are disposed perpendicular to the mounting plate 110, the lower groove edge 122 being disposed obliquely with respect to the upper groove edge 121. At this time, the gap between the groove bottom of the latch groove 120 and the latch 220 is greater than 0.2mm and less than 0.3mm (e.g., 0.25mm), and the gap between the groove bottom of the latch groove 120 and the latch 220 is greater than 0.4mm and less than 0.5mm (e.g., 0.45 mm). Meanwhile, the catching tenon 220 is formed of an upper tenon 221 and a lower tenon 222 to reduce the structural weight of the edge trim 200 of the present embodiment.

The advantage of such an arrangement is that the lower groove edge 122 is obliquely arranged to satisfy the technical effect of flaring adjustment of the clamping groove 120; the upper groove edge 121, the elongated plate 140 and the fixing plate 110 are always perpendicular to each other due to the horizontal arrangement of the upper groove edge 121, so that the fixing base 100 can be relatively stably installed at an internal corner formed between a wall (or a wall keel) and a ceiling.

As a further improvement, referring to fig. 3, a fastening edge end holding plate 230 vertically extends from the bottom of the edge-closing plate 210, a fastening edge end abutting portion 240 is formed at the top of the edge-closing plate 210, the width of the fastening edge end abutting portion 240 is equal to the width of the fastening edge end holding plate 230, and the thickness of the fastening edge end abutting portion 240 is equal to the thickness of the upper groove edge 121 of the clamping groove 120. After assembly, the buckle end holding plate 230 is disposed opposite to the fixed end holding plate 130, so that a new entrance of the holding space is formed between the edge of the buckle end holding plate 230 and the edge of the fixed end holding plate 130.

When the wall panel 300 with larger thickness is installed, the top edge of the wall panel 300 is linearly matched with the edge closing plate 210, i.e. a gap is formed between the outer facade (decoration surface) of the wall panel 300 and the lower edge of the edge closing plate 210. At this time, through the arrangement of the fastening edge clamping plate 230, the edge of the fastening edge clamping plate 230 can always abut against the outer vertical surface of the wall board, and has a higher clamping effect under the matching of the fastening edge clamping plate 230 and the fixed end clamping plate 130. Moreover, the edge-fastening clamping plate 230 can shield the gap between the lower edges of the wall panel and the edge-closing plate 210, so that the wall panel top edge-closing profile of the embodiment has a relatively good decorative effect.

In fig. 4, the top edge-closing profile of the wall panel of the present embodiment is shown in a state of completing the edge closing of the wall panel 300 with a larger thickness. The principle of its adaptation to the wall panel 300 of greater thickness is the same as in example 1.

One state of the wallboard top trim section of this embodiment in completing the trimming of a wallboard 300 of a lesser thickness is shown in fig. 5. Referring to fig. 5, when the inner wall surfaces of the upper and lower slot edges 121 and 122 and the upper and lower surfaces of the latch 220 are provided with the anti-return structures, the edge-receiving plate 210 deflects toward the fixing plate 110, the anti-return structure on the upper surface of the latch 220 is partially engaged with the anti-return structure on the upper slot edge 121, and the anti-return structure on the lower surface of the latch 220 is almost completely engaged with the anti-return structure on the inner wall surface of the lower slot edge 122, so that, in this technical scheme, the top edge-receiving profile of the wall panel of the present application can also satisfy the fixing and edge-receiving of the wall panel 300 having a thickness thinner than the standard thickness.

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.
