The connecting pipe 53 is preferably made of nylon material, which can effectively achieve a heat insulation effect.

[0026] The assembled building wall structure includes two or more plug-in frame units connected in sequence. The outer connecting members 51 of two adjacent connecting devices are connected by a transversely arranged outer connecting beam 131, and the inner connecting members 52 of two adjacent connecting devices are connected by a transversely arranged inner connecting beam 132. The outer connecting beam 131 is preferably an outer connecting beam made of nylon, and the inner connecting beam 132 is preferably an inner connecting beam made of nylon, which can achieve an effective heat insulation effect.

[0027] The outer connecting member 51 includes an outer connecting seat 511, which is in the shape of a regular hexahedron. The six faces of the regular hexahedron are outer connecting surfaces. At least three of the outer connecting surfaces are provided with outer plug-in portions 512 for plugging with the outer cross beam 41, the outer column 31, or the connecting tube 53. The outer plug-in portion 512 is provided with an outer locking hole for locking the outer plug-in portion 512 and the outer cross beam 41, the outer column 31, or the connecting tube 53.

[0028] The inner connecting member 52 includes an inner connecting seat 521, which is in the shape of a regular hexahedron. The six faces of the regular hexahedron are inner connecting surfaces. At least three of the inner connecting surfaces are provided with inner plug-in portions 522 for plugging with the inner cross beam 42, the inner column 32, or the connecting tube 53. The inner plug-in portions 522 are provided with inner locking holes for locking the inner plug-in portions 522 and the inner cross beam 42, the inner column 32, or the connecting tube 53.

[0029] The structure of the inner connecting member 52 is the same as that of the outer connecting member 51. The specific structure of the inner connecting member 52 and the outer connecting member 51 is described in detail in the Chinese utility model patent document named "frame connecting member" and the authorization announcement number is "CN210917766U", which will not be repeated here.

[0030] According to the specific connection structure, a plug-in portion is provided on the corresponding connection surface of the connection seat of the connection member, or no plug-in portion is provided.

[0031] Several plug-in parts are set on the connecting surface of the connecting seat of the outer connecting member 51 and the inner connecting member 52. Depending on the specific situation, two, three, four, five, or six plug-in parts can be set on the connecting surface of the connecting seat. However, in the drawings of this embodiment, only six plug-in parts are set on the connecting seat.

[0032] In the same plug-in frame unit, an insulating spacer is provided between the inner column 32 and the outer column 31 plugged into the same connecting device, and the insulating spacer connects the inner column 32 with the outer column 31. In two adjacent plug-in frame units, insulating spacers are provided between adjacent outer columns 31 and between two adjacent inner columns 32, and the insulating spacers connect the adjacent outer columns 31 and the insulating spacers connect the two adjacent inner columns 32. The outer column 31 and the inner column 32 are both composed of profiles, and the profiles have plug-in grooves, and the insulating spacer is plugged into the plug-in grooves of the profiles. A limit strip for limiting the position of the insulating spacer is also provided in the plug-in groove. The profile is a material commonly used in the construction industry, and its specific structure will not be repeated here.

[0033] The outer columns 31, the inner columns 32, and the insulating spacer strips of two adjacent plug-in frame units form an inner cavity to form a hollow insulating structure; two adjacent connecting devices form a square annular hole, and an insulating sealing plate for sealing the inner cavity is arranged in the square annular hole, which not only blocks the air flow but also improves the stability of the wall structure, thereby achieving the effects of thermal insulation and sound insulation, and is environmentally friendly, energy-saving, and emission-reducing.

[0034] Combination Figure 1 , Figure 2 , Figure 3 ,as well as Figure 4 As shown together, the foundation includes a cover plate, a support plate 10, and a bottom plate 9 from top to bottom. The outer column 31 and the inner column 32 are all slid through the cover plate and fixedly connected to the support plate 10. The cover plate includes a cover plate body 6, and the four sides of the cover plate body are all folded down to form a triangular folding portion 61, and a triangular weight-reducing hole 611 is provided on the folding portion 61. The lower end tip of the folding portion 61 is inserted into the insertion hole 91 opened on the bottom plate 9. The insertion hole 91 is preferably a strip hole. When the width of the folding portion 61 inserted into the insertion hole 91 is greater than the width of the strip hole, the cover plate body 6 cannot continue to move downward.

[0035] The support plate 10 is provided with a plurality of adjustment mechanisms for adjusting the height of the outer column 31 and the inner column 32. The adjustment mechanism includes an adjustment stud 11 fixedly connected to the support plate 10, and the adjustment stud 11 can freely pass through the cover plate body 6. The cover plate body 6 is provided with a light hole for the adjustment stud 11 to pass through, and the diameter of the light hole is larger than the diameter of the adjustment stud 11, so as to ensure that the adjustment stud 11 can pass through the light hole and can move freely up and down. The adjustment stud 11 is provided with a locking nut 12 for limiting the downward movement of the support plate 10, and the locking nut 12 is arranged above the cover plate body 6. The diameter of the locking nut 12 is larger than the diameter of the light hole, which can effectively limit the downward movement of the support plate 10.

[0036] The outer circumferences of the outer column 31 and the inner column 32 are both provided with buckles 7 , and the adjacent buckles 7 on the same side are locked by lock buckles 8 . The buckles 7 and the lock buckles 8 are provided on the upper surface of the cover body 6 .

[0037] The foundation further includes an arc-shaped ground anchor 1, the lower end of which is used to be inserted into the ground, and the upper end of which passes through the cover body 6 and is pressed against the corresponding buckle 7. The upper end of the ground anchor 1 is pressed against the buckle 7, and the upper end of the ground anchor 1 squeezes the buckle 7, so that the buckle 7 is always attached to the upper surface of the cover body 6, and then the buckle 7 is pressed against the corresponding column.

[0038] The adjacent outer columns 31 and inner columns 32 in two adjacent plug-in frame units share a foundation.

[0039] The following describes in detail the assembly process of the prefabricated building wall structure of the present invention:

[0040] The outer column 31 and the outer cross beam 41 are inserted into the outer plug-in part 512 of the outer connecting member 51 of the connecting device, and at the same time, the inner column 32 and the inner cross beam 42 are inserted into the inner plug-in part 522 of the inner connecting member 52 of the connecting device to assemble into a plug-in frame unit.

[0041] The bottoms of the outer column 31 and the inner column 32 are all passed through the through holes on the cover body 6 and fixedly connected to the support plate 10. If the foundation is driven on the sandy ground, the anchor 1 is caught in the sand, and the bottom plate 9 is placed on the sandy ground. The outer column 31 and the inner column 32 are adjusted in height as needed, and the outer column 31, the inner column 32, and the support plate 10 are moved up or down at the same time. After adjusting the height of the inner column 32 and the outer column 31, the locking nut 12 is screwed on the adjusting stud 11, and the locking nut 12 is made to abut against the upper surface of the cover body 6, effectively preventing the support plate 10 from moving down with the inner column 32 and the outer column 31, and ensuring the height of the inner column 32 and the outer column 31.

[0042] An outer composite heat-insulating board 21 is installed on the outer frame of the plug-in frame unit, and an inner composite heat-insulating board 22 is installed on the inner frame of the plug-in frame unit.
