FIG. 4A is a schematic view of a reentrant angular structure according to a fourth embodiment of the present disclosure; as shown in fig. 4A, the reentrant structure includes: the reentrant corner structure includes: the wing structure comprises a ridge structure body 111 and a wing structure body 121, wherein the ridge structure body 111 is bent outwards to form at least two bending parts 1111, and each bending part 111' protrudes out of the wing structure body 121 so as to level the internal corner surface according to the preset leveling angle. The keels described above in connection with fig. 1-3 may be secured to the spine structure 111.

Referring to fig. 4A again, in the present embodiment, the structure of the reentrant structure is described by taking one ridge structure 111 and two wing structures 121 as an example.

Specifically, in this embodiment, the preset leveling angle is 0 to 90 degrees. For example, if the base wall surface is a blank wall, the base wall surface has different degrees of concavity and convexity at different positions of the internal corner surface, so that the wall surfaces near two sides of the corner of the wall (the wall surfaces on each side can be called internal corner surfaces) are respectively in one plane as a whole by selecting different leveling angles. Or, for example, for some recreational products, to form a shaped assembly, i.e., a partially reentrant corner in one plane and another partially reentrant corner in another plane, with an angle between the planes.

Specifically, referring to fig. 5A and 5B, in the present embodiment, the ridge structure 111 has two bending portions 1111, each bending portion 1111 has a leveling reference point, and the two leveling reference points are distributed on two sides of a corner of the wall surface, so as to form one first gap a1 on each of the left and right sides of the ridge structure 111, so that during the leveling process, the internal corner structure 101 is transversely placed as a whole, thereby forming two leveling points on the left and right sides, and facilitating the rapid leveling process.

Of course, in other embodiments, as mentioned above, since the number of leveling reference points is related to the wing structure 121, and the number of wing structures is not particularly limited, the structures of fig. 5A and 5B are merely examples and are not limited.

Specifically, the ridge structure 111 is a first sheet structure having the bending portion 1111, so as to reduce the structural complexity of the internal corner structure 101, improve the construction speed of leveling on site, and facilitate quick fixing of the keel to the ridge structure 111.

It is to be understood that the structure of the first sheet-like structure is not limited to the three structures described above, and those skilled in the art may adopt other structures as long as the leveling process of the present application can be achieved.

Specifically, the wing structure 121 includes a second sheet-like structure and a gap adjusting structure, the wing structure 121 forms a first gap a1 by having a set height difference between the gap adjusting structure and the geometric center of the bent portion 1111, and forms the second gap a2 between the wing structure 121 and the female angle surface by the gap adjusting structure during the leveling process. The wing structure 121 includes a second sheet structure, thereby reducing the structural complexity of the reentrant corner structure 101 and increasing the construction speed of leveling on site.

Specifically, the length of each second sheet structure may be the same or different according to the requirement.

Specifically, in order to reduce the difficulty of production and the number of processes, in this embodiment, the second sheet structure and the first sheet structure are integrally formed.

Specifically, referring to fig. 5A described above, the gap adjusting structure includes an adjusting hole 1211 disposed on the second sheet-shaped structure, and an adjusting rod structure passing through the adjusting hole 1211 such that the wing structure 121 passes through the adjusting rod structure with a set height difference from the geometric center of the bent portion 1111 to form a first gap a1, and the second gap a2 is formed between the wing structure 121 and the negative angle surface by the adjusting rod structure during the leveling process.

In this embodiment, the adjustment holes 1211 and the adjustment rod structure are used to facilitate quick leveling. Meanwhile, the first gap A1 and the second gap A2 can be formed in the mode, and the leveling can be realized by changing the size of the second gap A2, so that the leveling precision is ensured, and the leveling difficulty is reduced.

Further, in this embodiment, the adjusting holes 1211 are through holes, the adjusting rod structure includes a nut 1212 and a screw 1213, the screw 1213 passes through the through holes, and one of the nuts 1212 and the screws 1213 on the screws 1213 at two ends of the through holes are screwed to the head of the through holes, so that the wing structure 121 passes through the adjusting rod structure and the geometric center of the bending portion 1111 with a set height difference to form a first gap a1, and in the leveling process, the adjusting rod structure is used to form the second gap a2 between the wing structure 121 and the negative angle surface.

Specifically, the screw 1213 may be a double-headed screw 1213, two heads penetrating through the through hole are screwed with a nut 1212, and the other head is screwed into the wall surface 100, so as to quickly and stably fix the internal corner structural member 101 to the wall surface 100. In addition, through the height position of the nut 1212 on the screw 1213 or the insertion depth of the screw 1213 into the wall surface 100, the size adjustment of the second gap a2 can be conveniently realized according to the flatness of the wall surface 100, and the leveling process is effectively realized.

Here, referring to fig. 5A and 5B, the number of the adjustment holes 1211 and the number of the adjustment rod structures correspond to the number of the wing structures 121.

Specifically, both of the adjusting holes 1211 may be through holes having openings. The wing structure 121 is movable left and right (including left and right movements caused by raising or lowering a leveling reference point where it is located) through the opening to adjust a leveling position. The direction of the opening is the radial direction of the through hole.
