The invention discloses a deep foundation pit supporting steel support mounting device and a mounting method thereof. The device comprises a front supporting frame, a rear supporting frame, a supporting bracket, a positioning block and an embedded bolt embedded in a crown beam; the front supporting frame comprises a front vertical plate and a front transverse plate, the rear supporting frame comprises a rear vertical plate and a rear transverse plate, and the supporting bracket comprises a vertical plate and a supporting groove; during installation, the lower portion of the front vertical plate and the front transverse plate as well as the rear vertical plate and the rear transverse plate are tightly attached and clamped to the front edge and the rear edge of the crown beam respectively, the embedded bolt penetrates out of an embedded bolt hole in the rear vertical plate and presses the rear vertical plate through a nut, the front transverse plate and the rear transverse plate are detachably connected through a connecting piece, the front transverse plate and the rear transverse plate are in butt joint, a complete positioning groove is formed in the butt joint position, the vertical plate is attached to the front vertical plate, bolt holes are aligned and connected through bolts, one side of the positioning block is simultaneously clamped to the upper portions of the front vertical plate and the vertical plate through clamping grooves, the lower portion of the other side of the positioning block is clamped in the positioning groove, and the supporting groove is used for supporting and limiting steel supporting ends. The device can be repeatedly used and is convenient to install and stable.
Description
technical field [0001] The invention relates to foundation pit support, in particular to a deep foundation pit support steel support installation device and an installation method thereof. Background technique [0002] At present, the deep foundation pit support method is to pre-embed the support steel plate before the concrete pouring of the crown beam, and then weld the bracket steel plate to the pre-embedded support steel plate, and then install the steel support. The above method has low work efficiency, wastes materials and low stability of the steel support. Contents of the invention [0003] The object of the present invention is to provide a deep foundation pit support steel support installation device and installation method thereof, which can be used repeatedly, and are easy to install and stable. [0004] The technical scheme adopted in the present invention is: [0005] A steel support installation device for deep foundation pit support, located at both ends ...
