The two embedded parts 12 are integrally connected to two sides of the body part 11, and the structure is symmetrical about the body part 11, specifically, the embedded parts 12 are connected to two sides of the body part 11 adjacent to the second end 1-B, the opposite sides 31 of the wall panels 3 are provided with splicing grooves 32 extending along the length direction of the opposite sides 31, the two embedded parts 12 are respectively matched with the splicing grooves 32 of two adjacent wall panels 3 in a clamping way, the splicing grooves 32 are provided with a first groove wall 321 close to the front surface of the wall panel 3, a second groove wall 322 close to the back surface of the wall panel 3 and a groove bottom 323, the embedded parts 12 are provided with an embedded part first end surface 121 facing the first groove wall 321, an embedded part second end surface 122 facing the second groove wall 322 and an embedded part third end surface 123 facing the groove bottom, wherein the embedded part first end surface 121 is flush with the second end 1-B of the body part 11, even if the body part 11 and the two embedded parts 12 form a T-shaped structure, the structural strength of the installation part 1 along the width direction of the gap is enhanced, a gap is formed between the third end face 123 of the clamping and embedding part and the groove bottom 323 of the splicing groove 32, therefore, the clamping and embedding part 12 has a certain assembling gap when being in clamping and matching with the splicing groove 32, so that the situation that the aging and the even fracture are aggravated by the extrusion of the groove bottom 323 when the installation part 1 is used for a long time and has the problems of aging and deformation and the like is avoided, and the second end face 122 of the clamping and embedding part is a bending face after being bent for multiple times.

The clamping part 12 is wrapped with a layer of flexible member matched with the shape of the clamping part, and preferably made of rubber. Based on the structure of the engaging portion 12, the flexible member 4 has a first flexible member portion 41, a second flexible member portion 42, and a third flexible member portion 43 that are integrally connected to each other, and the three portions respectively cover the first engaging portion end 121, the second engaging portion end 122, and the third engaging portion end 123 of the engaging portion 12, and since the first engaging portion end 121 is a flat surface, the first flexible member portion 41 is in frictional contact with the first groove wall 321 as a whole, and the second engaging portion end 122 is a bent surface, the second flexible member portion 42 is in frictional contact with the second groove wall 322, and the rest portions have a gap with the second groove wall 322. Generally, the first end surface 121 of the clamping portion and the first portion 41 of the flexible member play a role in mainly preventing the clamping portion 12 from relatively moving with the splicing groove 32 along the length direction thereof, and then the first end surface 121 of the clamping portion and the structural feature of the second end 1-B of the body portion 11 are flush with each other, so that the clamping portion has a good clamping matching performance, the second end surface 122 of the clamping portion and the second portion 42 of the flexible member play a role in partially preventing the clamping portion 12 from relatively moving with the splicing groove 32, and more play a role in supporting the clamping portion 12, so that the force of the first portion 41 of the flexible member attaching to the first groove wall 321 is improved, and in addition, since the second flexible member is only partially in frictional contact with the second groove wall 322, damping can be reduced when the clamping portion 12 is clamped into the clamping groove, and the assembly difficulty is simplified.

The second end of the main body 11 is provided with an insertion groove 113 extending along the length direction of the mounting piece 1, the insertion groove 113 extends from the notch to the groove bottom 1132 along the length direction of the section of the main body 11, the caulking strip 2 is provided with an insertion part 21 and a sealing part 22, the section of the insertion part 21 is in a slender structure, one end of the insertion part facing the back surface of the wall panel 3 is defined as a first end 2-A, one end of the insertion part facing the front surface of the wall panel 3 is defined as a second end 2-B, the sealing part 22 is in a flat structure, the middle part of the sealing part is integrally connected with the second end 2-B of the insertion part 21, the two caulking strips 2 in a T-shaped structure are formed, and the sealing part 22 is used for sealing the gap between the opposite edges 31 of the two wall panels 3.

The insertion part 21 includes two parts, one part is inserted and matched with the insertion groove 113 to be recorded as an insertion part second part 212, the other part is exposed outside the insertion groove 113 to be recorded as an insertion part first part 211, two sides of the insertion part second part 212 are provided with a plurality of first protruding structures S extending along the length direction of the mounting part 1 and arranged side by side, two groove walls 1131 of the insertion groove 113 are provided with one or a plurality of second protruding structures P extending along the length direction of the mounting part 1 and arranged next to the groove opening, and two second protruding structures P are arranged side by side along the position next to the groove opening on the groove wall of the insertion groove 113 in the present embodiment.

When the inserting part 21 and the inserting groove 113 are relatively displaced along the inserting direction, the second protrusion structures P may be pressed by the first protrusion structures S passing through in sequence, where the relative displacement is a process of inserting the inserting part 21 into the inserting groove 113 along the inserting direction. When inserting grafting portion 21, two first protruding structures S of the adjacent grafting portion 21 first end in grafting portion second portion 212 both sides contact with two second protruding structures P of adjacent notch at first, first protruding structure S extrudees second protruding structure P along the side direction, because notch position is far away from the tank bottom position and is compared other positions more easily and appear warping under the extrusion, thereby be located the interval grow between two second protruding structures P, the groove width of notch position is increased promptly, then improved the smooth degree that grafting portion second portion 212 inserted inserting grafting groove 113. It is worth noting that certain deformation can also occur to the first protruding structure S and the second protruding structure P in the extrusion process, and the thickness of the second part 212 of the insertion part is relatively narrow, so that the rigidity of the first protruding structure S integrated with the first protruding structure S is stronger, and the deformation degree of the first protruding structure S is smaller than that of the second protruding structure P, which is beneficial to the insertion of the insertion part 21, so that the caulking strip 2 can be made of a material with stronger rigidity than that of the installation part 1, so as to increase the deformation difference between the first protruding structure S and the second protruding structure P, and further improve the smoothness of insertion.

With the depth of the second part 212 inserted into the insertion groove 113 increasing, the first protrusion structures S on both sides of the second part 212 sequentially pass through the second protrusion structures P and exert a squeezing action on the second protrusion structures P, so that the groove width of the insertion groove 113 is intermittently increased and restored. Of course, when the second end of the insertion portion 21 abuts against the bottom of the insertion groove 113, that is, when the insertion portion 21 is completely inserted into the insertion groove 113, the second protrusion structure P and the first protrusion structure S are staggered and not extruded, and the insertion groove 113 is in a normal state and maintains a tight insertion fit with the second portion 212 of the insertion portion.

Further, the groove width of the insertion groove 113 is gradually reduced along the direction from the groove opening to the groove bottom, i.e. the insertion part second part 212 is more and more tightly matched with the insertion of the insertion groove 113 along with the insertion process, so as to improve the connection strength between the installation part 1 and the caulking strip 2, if there is no first protruding structure S and second protruding structure P, the damping during insertion is very large, not only the operation difficulty of the insertion fit is improved, even the second end of the insertion part 21 can not be abutted to the groove bottom of the insertion groove 113, but also the phenomenon that the insertion part 21 is broken off can be easily caused in the insertion process. Therefore, on the premise of providing the first protrusion structure S and the second protrusion structure P, the solution of gradually reducing the groove width of the insertion groove 113 can be implemented.

The first protrusion structure S has three continuous surfaces, i.e., a first slope surface S1 near the first end of the insertion portion 21, a second slope surface S2 near the second end of the insertion portion 21, and a first curved surface S3 connecting the two, wherein the first slope surface S1 and the second slope surface S2 may have a certain curvature. Correspondingly, the second protrusion structure P has three continuous surfaces, namely a third slope surface P1 close to the bottom of the insertion groove 113, a fourth slope surface P2 close to the notch of the insertion groove 113, and a second curved surface P3 connecting the third slope surface P1 and the fourth slope surface P2, wherein the third slope surface P1 and the fourth slope surface P2 may also have a certain curvature. In fact, the first and second convex structures S, P are structurally both centrosymmetric, so the first and fourth slope surfaces S1, P2 have substantially the same inclination, and the second and third slope surfaces S2, P1 have substantially the same inclination.

In addition, the inclination of the first slope surface S1 is smaller than that of the second slope surface S2, when the second portion 212 of the inserting part is inserted into the inserting groove 113, the first slope surface S1 and the fourth slope surface P2 are relatively displaced until the first curved surface S3 and the second curved surface P3 are pressed, and the inclination of the first slope surface S1 and the fourth slope surface P2 is smaller, so that the resistance during insertion is smaller. On the contrary, when the second portion 212 of the insertion part is separated from the insertion groove 113, the second slope surface S2 and the third slope surface P1 are relatively displaced, and the inclination of the second slope surface S2 and the third slope surface P1 is relatively large, so that the caulking strip 2 is not easily separated from the mounting piece 1 in the non-manual operation of the insertion part 21.

The intersection of the groove bottom 1132 of the insertion groove 113 and the two groove walls 1131 is provided with a recessed structure Q extending along the length direction of the mounting part 1, the cross section of the recessed structure Q is a circular arc line and has a certain accommodating space, and therefore, the two sides of the insertion part 21 are in clamping fit with the first protruding structures S closest to the first end and the corresponding recessed structures Q. Combining first protruding structure S, second protruding structure P, body portion 11 takes place elastic deformation when grafting portion second portion 212 inserts, and the increase of groove width intermittent type nature, finally the cooperation of pegging graft completely resets after both are connected inseparabler, difficult not hard up drops, recessed structure Q then can alleviate the stress that grafting portion second portion 212 produced when inserting to the mechanical destruction that prevents grafting portion second portion 212 appearance or the inelasticity irreversible deformation that causes easily. A gap is formed between the part of the concave structure Q corresponding to the groove bottom and the first end 2-A of the inserting part 21, and particularly, the first end of the inserting part 21 is of a plane structure, so that the concave structure Q and the second end can be absorbed due to processing errors, deformation caused by expansion with heat and contraction with cold, deformation stress during inserting and the like, and the wall panel 3 is prevented from arching and deforming.

The main body 11 is divided into two parts, the part with the insertion groove 113 is marked as a first main body part 111, the part extending from the first main body part 111 to the first end 1-A of the main body 11 is marked as a second main body part 112, the width of the first main body part 111 is greater than that of the second main body part 112, therefore, when the second insertion part 212 is inserted into the insertion groove 113, the first main body part 111 and the insertion groove 113 are intermittently deformed, and the deformation of the second main body part 112 is very small, therefore, the wall pasting part 13 connected with the second main body part will not be displaced relative to the back surfaces of the two wall panels 3, and the local stability of the structure is improved. In addition, the flexible piece also has a flexible piece fourth part 44 which extends to the gap between the opposite edges 31 of the two wall panels 3, the flexible piece fourth part 44 covers the body part first part 111 and is attached to the corresponding opposite edge 31 of the wall panel 3, and the protection effect on the body part 11 can be achieved, so that the mounting piece 1 has elastic buffering performance between the gaps of the two adjacent wall panels 3.

The X-direction splicing assembly M/Y-direction splicing assembly N is composed of one or more X-direction splicing assemblies M/Y-direction splicing assemblies N, and two end parts of the X-direction splicing assemblies M/Y-direction splicing assemblies N are intersected with the edge of the main wall body or are intersected with the Y-direction splicing assemblies/X-direction splicing assemblies M in a T shape. For the partition of the X-direction splicing assembly M/Y-direction splicing assembly N, the shorter one is partitioned by the longer one when the X-direction splicing assembly M/Y-direction splicing assembly N is intersected, namely, any two X-direction splicing assemblies M and Y-direction splicing assemblies N are intersected, the X-direction splicing assembly M/Y-direction splicing assembly N with the shorter length and the Y-direction splicing assembly N/X-direction splicing assembly M with the longer length are partitioned into two X-direction splicing assemblies M/Y-direction splicing assemblies N at the intersection, and the partitioned end parts of the two X-direction splicing assemblies M/Y-direction splicing assemblies N are respectively intersected with the Y-direction splicing assembly N/X-direction splicing assembly MT in an MT shape.
