Description

Technical Field

[0001] The utility model relates to the technical field of industrial and civil construction engineering, in particular to a reinforced concrete wall waterproof node connection structure. Background Art

[0002] According to the provisions of the standards "Concrete Structure Design Code" and "Building Seismic Design Code", buildings and structures should be set up with expansion joints as required. In order to prevent the settlement difference between different structural units and the problem of wall cracking caused by the retaining wall crossing the expansion joint, the most reasonable approach is to set up expansion joints between the double-column structures of the concrete frame and take simple and effective waterproofing measures to meet the normal use of the building; but in actual projects, due to the presence of a large number of stirrups in the frame columns, the position of the double columns of the frame cannot be directly equipped with embedded waterstops in the columns. The stirrups will affect the continuous setting of the waterstop and fail to achieve the purpose of waterproofing. Utility Model Content

[0003] In view of the above-mentioned shortcomings and deficiencies, the utility model provides a reinforced concrete wall waterproof node connection structure, which meets the waterproof defense requirements without adding complex structural components and construction measures, and can avoid the problem of wall cracking caused by the wall crossing the structural joints.

[0004] In order to achieve the above-mentioned purpose, the main technical scheme adopted by the utility model is: a reinforced concrete wall waterproof node connection structure, including a reinforced concrete wall, a foundation short column and a waterproof buttress column, the reinforced concrete wall and the foundation short column are seamlessly cast as a whole, the thickness of the foundation short column is greater than that of the reinforced concrete wall, and deformation joints are arranged between the foundation short columns, the waterproof buttress column and the foundation short column are seamlessly cast as a whole, and waterstop strips are arranged inside and outside the waterproof buttress column.

[0005] The total length of the waterstop is not less than 300 mm. An embedded waterstop is provided at the central deformation joint inside the waterproof buttress column, and an external waterstop is provided at the deformation joint outside the waterproof buttress column.

[0006] The width of the deformation joint is 20-30 mm, the thickness of the waterproof buttress column is not less than 300 mm, and the deformation joint is filled with caulking material.

[0007] The waterproof buttress column is anchored into the foundation short column and stabilized with the foundation short column by the steel bars arranged inside. The steel bars are divided into two separate parts, which are arranged on both sides of the embedded waterstop respectively, without damaging the waterstop and preventing the waterstop from passing through.

[0008] The utility model has the following beneficial effects and advantages:

[0009] The utility model, through the connection structure, firstly, can meet the waterproofing requirements of underground structures of different levels by arranging waterstops in the waterproof buttress columns; secondly, during construction, because the waterproof buttress columns are added with the help of the foundation short columns and are cast integrally with the foundation short columns, there is no need for complicated construction measures, no need to add complicated structural components, and the waterproofing problem of the expansion joint is solved without construction burden and safety hazards.

[0013] The utility model is further described below in conjunction with the accompanying drawings of the specification. Figure 1 As shown, the utility model is a reinforced concrete wall waterproof node connection structure, including a reinforced concrete wall 1, a foundation short column 2 and a waterproof buttress column 3, the reinforced concrete wall 1 and the foundation short column 2 are seamlessly cast as a whole, the thickness of the foundation short column 2 is greater than that of the reinforced concrete wall 1, a deformation joint 6 is arranged between the foundation short columns 2, the waterproof buttress column 3 and the foundation short column 2 are seamlessly cast as a whole, and a water stop strip 5 is arranged inside and outside the waterproof buttress column 3.

[0014] The total length of the waterstop 5 is not less than 300 mm. An embedded waterstop is provided at the central deformation joint inside the waterproof buttress column 3, and an external waterstop is provided at the deformation joint outside the waterproof buttress column 3.

[0015] The type of waterstop 5 can be selected according to the waterproof level required by the building, and one or two combinations of embedded waterstop and external waterstop, removable waterstop, waterproof sealing material, external waterproof membrane or external waterproof coating can be used.
