Anti-cracking and anti-collapse structure for newly built enclosing wall at alpine-cold region

Abstract

The invention discloses an anti-cracking and anti-collapse structure for a newly built enclosing wall at an alpine-cold region, and the structure provided by the invention comprises a wall body, wall piers, a bottom beam, a sand layer, a base and a foundation. The wall body, the wall piers and the base are in built structures. The bottom beam is a reinforced concrete prefabricated part and the bottom beam is a straight rod beam or a circular arc beam. The base is built in the foundation with hewn stone, mortar and asphalt are plastered on the periphery for constituting a waterproof layer, thesand layer is arranged between an asphalt layer and the foundation for separating and constituting a stress absorption structure, the bottom beam is erected at the bottom ends of the two adjacent wall piers on the same horizontal line, a certain distance is reserved between the bottom surface of the middle part of the bottom beam and the upper surface of the foundation, and the wall body and the wall piers are synchronously built on the bottom beam and the base respectively. The wall body is directly built on the bottom beam, even the foundation is iced and external expansion force is generated, the external expansion force can not be acted on the wall body, and the wall body can not generate stress cracks and can not even been pushed over by stress, so that the newly built enclosing wallis firm and has no possibility of repair and reconstruction in the following year.

Description

technical field [0001] The invention relates to a building structure, in particular, the invention relates to an anti-crack and anti-fall structure for newly built walls in alpine regions. Background technique [0002] The fence is a kind of non-load-bearing building, and its basic structure requirements are relatively simple during construction. As long as the ground is solid, a conventional foundation with a depth of several hundred millimeters is sufficient to meet the structural strength requirements. Building construction in alpine regions usually avoids the cold winter. As long as the construction is carried out in accordance with the building codes during other periods, the built walls will fully meet the quality requirements and will not crack or collapse on their own. In reality, after the first winter, the newly built walls in alpine regions will always have some cracks, and in severe cases, the walls may even tilt or collapse. After this type of problem occurs, e...

Problems solved by technology

After such problems occur, even if the damaged walls are torn down, strengthened and rebuilt, the same problem may still occur in the coming year, and this problem has always plagued people in alpine regions

If there are differences in the geological conditions of the foundation where the new fence is located, it will inevitably result in a difference in water content. After the foundation freezes, due to the unequal expansion, the external expansion force will be unequal, and the enclosure will inevitably produce cracks under the unequal external expansion force. In severe cases, it may even cause the wall to tilt or collapse

In order to overcome the above problems, the method of deepening the foundation is usually adopted in the alpine region to avoid the "flouring" of the foundation of the newly built fence. Although the existing technology is effective, it still cannot completely solve the problem of stress cracks in the fence
