Description

Modularized steel enclosing purlin assembly convenient to install rapidly Technical Field The utility model relates to the field of building construction, in particular to a modularized steel enclosing purlin assembly convenient to install quickly. Background Steel purlin is generally a supporting member used in building structures, and is mainly used for enhancing stability of soil, preventing soil from slipping or collapsing, and bearing and dispersing forces from soil pressure or other external forces, especially in the process of supporting foundation pits, tunnel engineering or underground structure construction. In the construction process of the traditional steel purlin, the steel sheet pile is usually constructed firstly, then the steel purlin is installed and fixed on the steel sheet pile, and then the transverse support column is hoisted and installed. However, the steel purlin has a relatively large volume and is relatively heavy, so that the installation process of the steel purlin assembly is inconvenient, and the steel purlin assembly needs to be improved. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide a modularized steel enclosing purlin assembly which is convenient to install quickly and has the effect of convenient installation and construction. The technical aim of the utility model is achieved by the following technical scheme that the modularized steel enclosing purlin assembly convenient for quick installation comprises: The steel sheet pile is used for the construction of a steel sheet pile, is vertically inserted into the bottom of the foundation pit in a wave shape; the I-steel purlin is transversely arranged on the inner side of the steel sheet pile; The steel supports are horizontally arranged between the pair of I-steel purlins, each steel support comprises a fixed head, a movable head and a support column, and each support column is arranged between the corresponding fixed head and the corresponding movable head; The bearing plate is in a U-shaped clamping connection and is fixed on the I-steel purlin and used for bearing the steel support; the fixed head with the tip of loose head all is provided with the mounting panel of rectangle, be provided with the slide rail that is the U-shaped setting on the bearing board, slide rail and opening set up, and are used for supplying the mounting panel slides the embedding.
