Description

Technical Field

[0001] The utility model relates to the technical field of door opening reinforcement, in particular to an ALC strip board door opening hanging bar fixing and installation structure. Background Art

[0002] Autoclaved aerated concrete wall panels have been introduced from foreign countries in recent years due to their energy-saving and environmental protection, effective use of industrial waste, and factory production, and are widely used in various industrial and civil buildings.

[0003] Although walls constructed with ALC strips have many advantages, there are still some problems in actual use. For example, when ALC strips are installed vertically, only one strip is installed in the upper and lower directions of one layer. ALC is a porous material with low strength, which is not conducive to fixation with general self-tapping screws. This results in low strength at the door opening of the wall, which is difficult to meet the design requirements.

[0004] At present, in actual construction, after the door opening structure of the ALC wall is completed, the ALC strips on the top need to be reinforced with angle steel, which not only makes the construction complicated and prolongs the construction period, but also has an adverse effect on the later wall decoration of the ALC wall; at the same time, because the force transmission path at this place is not ideal, it is easy to cause door frame deformation and wall cracking in the later stage.
