Cave mouth structure on bearing wall and method for forming cave mouth thereon

Abstract

The invention discloses a cave mouth structure on a bearing wall and a method for forming the cave mouth thereon. The structure comprises a bearing wall body (1) and a cave mouth (2) formed on the bearing wall body (1), wherein a steel member (3) is arranged on the bearing wall body (1) above the cave mouth (2), and both ends of the steel member (3) are respectively positioned in bearing slots (4)on both ends of the upper part of the cave mouth (2). The invention adopts the structure that the steel member is arranged above the cave mouth which needs to be formed, both ends of the steel memberare supported on the bearing wall on both ends of the upper edge of the cave mouth, and therefore a larger cave mouth can be formed on the wall body without demolishing the wall body or unloading load on the wall; and the strength and the stability of the wall can be prevented from being influenced.

Description

Technical field: [0001] The invention relates to an opening structure on a wall and a method for opening the same, in particular to an opening structure on a load-bearing wall and a method for opening an opening on the load-bearing wall. technical background: [0002] Due to the rapid update of equipment technology at this stage, many factories often face energy-saving technical transformation projects, such as electrolytic aluminum plants, alumina plants, and sponge titanium plants. When carrying out energy-saving technical transformation, in order to reduce expenses, the existing factory buildings and workshops are generally used. When performing technical transformation projects on existing factory buildings and workshops, it is often encountered that large holes are opened on the walls of buildings. However, since the walls of factories and workshops are mostly load-bearing walls or self-supporting walls, and there is a large load on them, the usual method is to unload o...

When carrying out energy-saving technical transformation, in order to reduce expenses, the existing factory buildings and workshops are generally used. When performing technical transformation projects on existing factory buildings and workshops, it is often encountered that large holes are opened on the walls of buildings. However, since the walls of factories and workshops are mostly load-bearing walls or self-supporting walls, and there is a large load on them, the usual method is to unload or demolish part of the building, which not only brings great inconvenience to production, but even leads to shutdown ; and it will take a lot of manpower, material and financial resources to unload, install or demolish buildings
