[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1:

[0035] See also Figures 1 to 5 A detachable wall of an assembled building includes at least two unit walls 10. The unit walls 10 are prefabricated components, which may be concrete components or components of other materials.

[0036] The unit walls 10 can be connected side by side to form a building wall, and the length of the building wall determines the number of unit walls 10 used.

[0037] like Figure 1 and Figures 3 to 5 As shown, the upper and lower sides of the front side of the unit wall 10 are respectively provided with tie-locking mechanisms 20 with the same structure, and the front side of the unit wall 10 is locked left and right by providing the tie-locking mechanisms 20;

[0038] Specifically, the tie-locking mechanism includes T-slots 21 opened at the left and right ends of the front face of the unit wall 10, and the T-slots 21 at the left and right ends are symmetrically distributed, the short side groove cavity of the T-slot 21 is connected to the side of the unit wall 10, and a hole plate 22 is fixedly arranged in the short side groove cavity of the T-slot 21, and a connecting hole 23 is opened between the left and right ends of the T-slots 21, and a threaded tie rod 24 is movably inserted in the connecting hole 23, and the length of the threaded tie rod 24 is less than the left and right width of the unit wall 10, so as to ensure that when the unit wall 10 is disassembled from the front and rear directions, the threaded tie rod 24 will not be too long to cause interference and obstruction ; A fixing nut 25 is provided at each end of the threaded tie rod 24; in the installed state, the two fixing nuts 25 are respectively abutted against the inner groove wall of the right side T-slot 21 of the current unit wall 10 and the orifice plate 22 of the right side T-slot 21 of the adjacent unit wall 10 to achieve the left-right tie between the two adjacent unit walls 10; or in the installed state, the two fixing nuts 25 are respectively abutted against the inner groove wall of the left side T-slot 21 of the current unit wall 10 and the orifice plate 22 of the left side T-slot 21 of the adjacent unit wall 10 to achieve the left-right tie between the two adjacent unit walls 10.

[0039] like Figure 2 As shown, the upper and lower sides of the back of the unit wall 10 are respectively provided with mortise and tenon positioning mechanisms 30 with the same structure, and the back of the unit wall 10 is positioned up and down by providing the mortise and tenon positioning mechanisms 30;

[0040] Specifically, the mortise and tenon positioning mechanism includes a tenon block 31 embedded in one of the left and right sides of the unit wall 10 and a mortise groove 32 opened on the other side of the unit wall 10. The tenon block 31 and the mortise groove 32 are engaged with each other to realize the limit constraint in the up and down directions between two adjacent unit walls 10; the tenon block 31 is a removable embedded part. When the unit wall 10 is prefabricated, a tenon block 31 installation groove is reserved. The tenon block 31 is temporarily fixed to the unit wall 10 by fixing nails. After the tie-locking mechanism 20 is installed, the tenon block 31 can be removed; on the one hand, the tenon block 31 can be recycled and reused to save the loss of building materials, and on the other hand, the tenon block 31 is prevented from hindering the removal of the unit wall 10 from the front and back directions; and the tenon block 31 is a mechanism protruding from the side of the wall, and if it is not removed, it will hinder the wall end from fitting and connecting with the building surface.

[0041] Furthermore, the tenon block 31 and the mortise groove 32 are L-shaped structures. After the tenon block 31 and the mortise groove 32 are engaged, a gap is left in the left and right directions for fastening and locking. In this way, when installing the unit wall 10, the tenon blocks 31 and the mortise grooves 32 on the rear sides of the two unit walls 10 are first aligned for pre-engagement. After engagement, in addition to up and down positioning, the tenon block 31 and the mortise groove 32 of the L-shaped structure can also be used to achieve pre-fixation in the left and right directions; so as to facilitate the subsequent installation of the front side fastening and locking mechanism 20 for final fastening and fixing.

[0042] Example 2

A bolt through hole is opened on the T-shaped cover plate 40, and an internal threaded hole seat 42 is provided in the T-slot 21 at the position corresponding to the bolt through hole. The cover plate bolt 41 is screwed with the internal threaded hole seat 42 through the bolt through hole to lock the T-shaped cover plate 40 on the T-slot 21; and the T-shaped cover plate 40 is flush with the front side of the unit wall 10; after the installation construction is completed, the T-shaped cover plate 40 is used to cover the T-shaped cover plate 40, which can improve the flatness of the wall surface and facilitate the subsequent wall decoration construction; and when disassembling the unit wall 10, there is no need to carry out large-scale demolition construction, and it can also facilitate re-disassembly and adjustment during the assembly and installation process.

[0044] Example 3

[0045] In order to facilitate the forming of the pre-supporting groove structure on the wall surface and make it firm and durable; the unit wall 10 includes a built-in steel skeleton 11 and a concrete body 12 poured and filled around the steel skeleton 11 during prefabrication; further, the inner wall of the T-slot 21 is provided with a T-slot lining 40, which is a cast engineering plastic lining or hardware material, and the outer wall of the T-slot lining 40 is fixedly welded to the transverse reinforcement and / or longitudinal reinforcement of the steel skeleton 11, and the mortise groove 32 has a mortise groove lining 50, which is a cast engineering plastic lining or hardware material, and the outer wall of the mortise groove lining 50 is fixedly welded to the transverse reinforcement and / or longitudinal reinforcement of the steel skeleton 11; in this way, the T-slot lining 40 and the mortise groove lining 50 are integrally connected to the steel bars inside the wall, and are constructed before the pre-support pouring of the wall, which is convenient for casting and forming, and firm and durable.
