Description
Technical Field
The utility model relates to a deep basal pit struts specifically is an assembled anti side force bracket that is used for deep basal pit shaped steel to support.
Background
In recent years, the steel support for the deep foundation pit is rapidly expanded and applied to deep foundation pit support. Usually, the deep foundation pit steel section supports are supported by brackets which are arranged at equal intervals in the vertical direction. The bracket is composed of a vertical column and a joist, and the vertical column is inserted into the vertical column pile. The bracket commonly used at present can only restrict the vertical displacement of deep basal pit shaped steel support in bracket department, can't restrict the horizontal displacement of deep basal pit shaped steel support in bracket department. The bearing capacity of the deep foundation pit steel support is determined by the calculated lengths of the deep foundation pit steel support in the vertical plane and the horizontal plane, and the bearing capacity is lower when the calculated length is larger. When the vertical displacement of the deep foundation pit profile steel support at the bracket is limited by the bracket, the calculated length of the deep foundation pit profile steel support in the vertical plane is the distance between the brackets. When the bracket can not limit the displacement of the deep foundation pit profile steel support in the horizontal plane, the calculated length of the deep foundation pit profile steel support in the horizontal plane is the full length of the deep foundation pit profile steel support. When the length is calculated in the horizontal plane to obtain the full length of the deep foundation pit steel support, the bearing capacity of the deep foundation pit steel support is greatly reduced, and waste is caused. The current commonly used brackets have the following main disadvantages: 1. the assembly is not available, the field welding is needed, and the construction is difficult; 2. the material is not recycled, so that the material waste is caused, and the manufacturing cost is high; 3. the horizontal displacement of deep foundation pit shaped steel support in bracket department can not be restricted, is unfavorable for the performance of deep foundation pit shaped steel support bearing capacity, causes the waste.
