Problems solved by technology
With this kind of restraint structure, the self-deformation and structural settlement relieved by the rubber mat are limited, and when the rubber mat loses its activity, the partition wall is prone to deformation and cracking, which in turn causes cracking and deformation of the surface layers such as wallpaper and tiles with the partition wall as the base layer, affecting Aesthetic requirements and functional use

Embodiment Construction
[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Such as Figure 1-11 As shown, the present invention provides a light steel keel system for preventing partition walls from cracking, including:
[0029] The vertically expandable sky keel directly fixed on the roof wall 1 of the building;
[0030] The ground keel 3 directly fixed on the building ground 2; specifically, such as image 3 As shown, the ground keel and the building ground are connected by bolts 4, without rubber pads in between, the fixed distance between the bolts 4 is 600mm, and the first fixed point is about 100-150mm away from the adjacent side wall;
[0031] The vertical keel 5 connected with the sky keel and the ground keel 3 respectively; specifically, as Figure 4 and 5 As shown, the upper end of t...

The invention provides a lightgage steel joist system capable of preventing a partition wall from cracking. For solving the problem that in a conventional joist system, in case of serious influence of self deformation and structural settlement, a whole partition wall cracks, so that the appearance requirement and the using function are influenced, by use of a new constraint structure and change of the connection ways of joists and a structure, the whole joist has a certain activity space in the vertical direction, skin plates and a new joist system are convenient for being fixed, the skin plates are allowed to displace in the vertical direction, and the skin plates have a certain activity space in the vertical direction in the plane of the skin plates; when the building structure displaces or deforms, the skin plates can do limited unconstrained simple activity through vertically telescopic ceiling joists, longitudinal stress is relieved, and the cracking risk of a gypsum board wall, which is caused by building settlement and horizontal air pressure, is reduced; the cracking-preventing partition wall is simple, innovative and efficient; and rubber gaskets reserved for deformation cushioning do not need to be additionally arranged between the ceiling joists and the top wall of a building and between ground joists and the ground of the building.
Description
technical field [0001] The invention relates to a light steel keel system for preventing partition walls from cracking. Background technique [0002] The traditional partition wall keel system uses nails and bolts to fix the partition wall on the upper and lower structures as a whole, and rubber pads are used between the keel and the partition wall to alleviate the impact of deformation and settlement. With this kind of restraint structure, the self-deformation and structural settlement relieved by the rubber mat are limited, and when the rubber mat loses its activity, the partition wall is prone to deformation and cracking, which in turn causes cracking and deformation of the surface layers such as wallpaper and tiles with the partition wall as the base layer, affecting Aesthetic requirements and functional use. Contents of the invention [0003] The purpose of the present invention is to provide a crack-preventing partition wall, which can prevent the partition wall fro...
