Embodiment Construction

[0020] Exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the application, but are not intended to exhaust all possible ways of the application, nor are they used to limit the scope of the application.

[0021] Such as figure 1 As shown, the application provides a shear key installation structure, the installation structure of the shear key includes a column 1, a column base plate 2, a column base bolt 3, a nut 4, a shear key reserved hole 5, a foundation Short columns 6, shear keys 7, supports 8.

[0022] The column 1 can be columnar, for example, can be made of a square column. The column base plate 2 is connected to the lower end of the column 1. The column 1 and the column base plate 2 can be fixedly connected by, for example, welding. The column base plate 2 is provided with an installat...

Abstract

The invention provides an installation structure and an installation method of a shear key. The installation structure of the shear key comprises a column, a column base bottom plate, a column base bolt, a shear key preformed hole, a foundation short column and the shear key, wherein the column base bottom plate is fixedly connected to the column, the column base bolt is pre-buried in the foundation short column, the column base bottom plate is connected to the column base bolt, the shear key preformed hole is formed in the foundation short column, the shear key is contained in the shear key preformed hole and protrudes out of an opening of the shear key preformed hole, a mounting hole is formed in the column base bottom plate, and the shear key penetrates through the mounting hole and extends into the column. The shear key is inserted into the column base bottom plate, the shear key does not need to be welded to the lower portion of the column base bottom plate in advance, the effective use height of the modular building can be high, when the modular building is assembled in a factory, the modular building is supported by the column base bottom plate, and the problem that a pre-welded shear key is difficult to keep stable when being used for supporting the modular building is avoided.

Description

technical field [0001] The application relates to a building component, in particular to an installation structure and an installation method of a shear key. Background technique [0002] The "Steel Structure Design Standard" clearly stipulates that exposed column foot bolts should not be used to bear the horizontal reaction force at the bottom of the column foot. This horizontal reaction force is borne by the friction between the bottom plate and the concrete foundation or by setting a shear key. In addition, the shear failure of column bolts occurs in the concrete foundation, which is not easy to find and usually difficult to take reinforcement measures. Therefore, the design of steel structure shear key is very important in the whole steel structure design. The shear key is usually welded vertically to the horizontal steel plate on the bottom of the column with thicker channel steel or I-beam, and buried in the reserved shear groove in the foundation, and is generally po...
