[0001] The utility model relates to the technical field of building structure systems, in particular to an inner wall unit, an inner wall body and a building. Background Art

[0002] Building walls include interior walls and exterior walls. In addition to their supporting function, they also need to have good thermal insulation, fire prevention, sound insulation, etc. For the interior walls of buildings, some decoration is usually required.

[0003] Since the indoor space is a relatively closed space and people live and work indoors for a long time, an important requirement for buildings is insulation. Specifically, when the temperature is low, keep the indoor temperature higher than the outdoor temperature; when the temperature is high, keep the indoor temperature lower than the outdoor temperature. The purpose of insulation is to keep the indoor temperature in a relatively stable state at all times, creating comfortable temperature conditions for people's lives and work. The existing building walls have poor insulation effects. For indoor walls, increasing the thickness of the wall to improve the insulation effect will also lead to the problem of reduced indoor usable area. Existing building walls also generally have the problem of poor sound insulation effects, especially for the interior walls of buildings, where sound insulation effects are particularly important.

[0004] The interior walls of existing buildings are built on-site, which not only has low construction efficiency but also unstable quality.

The adjacent first composite wall panels mentioned here refer to the first composite wall panels on other inner wall units, and the adjacent second composite wall panels refer to the second composite wall panels on other inner wall units.

[0029] The upper keel, the lower keel, the first composite wall panel and the second composite wall panel of the above embodiment can all be prefabricated in the factory, and the various parts can be assembled on site during construction, which not only facilitates transportation, but also improves the construction efficiency of the inner wall. The construction is quick and convenient, and the prefabricated first composite wall panel and the second composite wall panel have good flatness. The middle part of the above inner wall unit has a hollow cavity, which can achieve good sound insulation and noise isolation effects, and also improves the thermal insulation performance of the wall. The hollow cavity can be used to arrange wire pipes or water pipes without affecting the outer structure of the inner wall unit. The pipeline layout is safe and easy to repair.

[0030] The first composite wall panel and the second composite wall panel in the inner wall unit of the above embodiment may be completely identical or different; the first connection structure and the second connection structure may be completely identical or different.

[0031] For example, the first composite wall panel 3 and the second composite wall panel 4 each include a frame 31, an inner lining board 32, an outer lining board 33 and a filler 34. The inner lining board 32 and the outer lining board 33 are both fixed to the frame 31, and the inner lining board 32 and the outer lining board 33 are parallel to each other. The filler 34 fills the gap between the inner lining board 32 and the outer lining board 33; the frame 31 is fixed to the upper keel 1 and the lower keel 2, and the first connection structure and the second connection structure are both arranged on the frame 31. The first composite wall panel 3 and the second composite wall panel 4 are stably connected to the upper keel 1 and the lower keel 2 through the frame 31, and the inner lining board, the outer lining board and the filler therebetween achieve the effects of heat preservation, fire prevention, moisture prevention, sound insulation and noise isolation.

For example, the thickness of the first composite wall panel is in the range of 2-10 cm, the thickness of the second composite wall panel is in the range of 2-10 cm, the width of the hollow cavity is in the range of 1-40 cm, and the overall thickness of the interior wall unit is in the range of 8-50 cm. For example, the thickness of the first composite wall panel and the second composite wall panel are both 5 cm, and the overall thickness of the interior wall unit is in the range of 40 cm.

[0037] In some embodiments, the hollow cavity 5 is filled with glass wool boards and blankets, rock wool boards and blankets, or mineral wool boards and blankets for sound absorption and sound insulation. By filling these fillers, the sound insulation effect can be further improved.
