Background
In the reconstruction of storage buildings, non-bearing masonry infill walls are added to the bottom layer of the building without a basement and a space layer because of building function adjustment, and the newly added infill walls are required to be vertically clung to the original building structure. The newly added non-bearing filling wall has no other bearing requirements except the dead weight, and the foundation generally adopts an inverted trapezoid foundation (commonly called a shoe-shaped ingot foundation) under the wall for reasons of cost and construction convenience, backfilling soil and tamping are carried out under the foundation, and a transition constructional column is not arranged at the junction of the new wall and the old wall. According to the prior engineering practice, the following quality defects are caused by the method: 1. quality defects such as uneven backfill soil treatment and the like are liable to have great influence on the overall quality of the newly-added masonry; 2. because the newly added masonry is different from the original structure (comprising a wall body) in basic form or supporting mode, even if tamping and filling treatment is adopted for backfilling soil at the lower part of the newly added masonry, differential settlement is unavoidable, and masonry cracks are easy to generate; 3. the newly added filling wall is inconsistent with the original structure (comprising the wall body) material, and an upper through seam and a lower through seam are formed between the newly added filling wall and the original wall body, so that the joint part is easier to crack.
Disclosure of Invention

The technical scheme provided by the utility model is as follows: the connection structure of the newly added bottom post-built filling wall and the original building structure without the bottom plate comprises the newly added bottom post-built filling wall and the original building structure, and the newly added bottom post-built filling wall is vertically clung to the original building structure; reinforcing steel bars and shearing resistant reinforcing ribs are respectively implanted into the original building structure, the reinforcing steel bars extend and are anchored in the newly added bottom post-built filling wall, and the shearing resistant reinforcing ribs extend and are anchored in the newly added bottom post-built filling wall foundation; the bottom of the foundation of the newly added bottom layer built filling wall is provided with through long steel bars.
The foundation of the newly added bottom layer built filling wall is an inverted trapezoid foundation under the wall.
The reinforcing steel bars are not less than two, the diameter of the reinforcing steel bars is not less than 6mm, the vertical distance between the reinforcing steel bars is not more than 500mm, the depth of the reinforcing steel bars implanted into the original building structure is not less than 200mm, and the reinforcing steel bars extend and are anchored in the newly-added bottom layer rear masonry filling wall to be not less than 700mm.
The shearing resistant reinforcing ribs are not less than three, the diameter of the shearing resistant reinforcing ribs is not less than 12mm, the depth of the shearing resistant reinforcing ribs implanted into the original building structure is not less than 200mm, and the shearing resistant reinforcing ribs extend and are anchored at the middle part of the foundation of the newly added bottom layer back-built filling wall to be not less than 700mm.
The through-length steel bars refer to the whole steel bars penetrating through the newly added bottom layer and then building the filling wall foundation. The total length of the steel bars is not less than three, the diameter of the total length of the steel bars is not less than 12mm, the total length of the steel bars is implanted into the original building structure, and the implantation depth is not less than 200mm.
The diameter of the through long steel bars is not less than 8mm, and the distance of the through long steel bars is not less than 200mm.
The utility model implants reinforcing steel bars in the original building structure and extends and anchors the reinforcing steel bars in the newly added bottom layer to strengthen the connection between new and old walls in the back-built filling wall, implants shearing resistant reinforcing steel bars in the original building structure and anchors the reinforcing steel bars in the base of the newly added bottom layer to strengthen the connection between new and old structures in the back-built filling wall, and adds through long reinforcing steel bars at the bottom of the base of the newly added bottom layer to strengthen the bending rigidity of the base. The newly added bottom post-built filling wall generally adopts a shoe-shaped gold ingot foundation on the treated backfill so as to reduce the foundation excavation quantity, and the backfill treatment quality has a larger influence on the overall quality of the later-stage masonry. Meanwhile, the vertical through seam is inevitably formed between the newly added bottom layer post-built filling wall and the original building structure due to different construction time, and the settlement difference possibly occurs between the newly added bottom layer post-built filling wall and the original structure due to different supporting modes, so that the quality of the masonry is affected.
The structure provided by the utility model can strengthen the rigidity of the newly added bottom layer post-built filling wall foundation and the connection between the newly added bottom layer post-built filling wall foundation and the original building structure, effectively improve the quality problems of masonry cracks and the like caused by the unfavorable conditions of backfill soil treatment defects, differential settlement, masonry through-joints and the like, has simple structure and convenient construction, makes up the defects of related atlas, and can be used as a reference method of similar engineering through engineering practice inspection.
