The invention discloses a steel template
system used for a subway foundation pit supporting beam. The steel template
system comprises a main beam template and
diagonal bracing beam templates, wherein the main beam template is located in the middle, the
diagonal bracing beam templates are located at the two ends, the main beam template and the
diagonal bracing beam templates are formed by steel templates in a parallel and opposite mode, the bottoms of the steel templates are provided with foot braces which can be locked with the ground, the oppositely-arranged steel templates are connected and supported through jack screws at the tops of the steel templates, the outer side of each steel template is provided with an outer supporting framework which can support and abut against the steel templates, each outer supporting framework comprises a
portal frame and supporting rod assemblies, each
portal frame is provided with a
portal frame cross beam and stand columns, the supporting rod assemblies are installed on the stand columns and used for supporting the steel templates, each supporting rod
assembly comprises a supporting board used for abutting against the steel templates, and a supporting rod used for adjusting the supporting board to move back and forth, each supporting board is connected to the end portion of one supporting rod, and the supporting rods are screws and penetrate through the stand columns and are in threaded connection with the stand columns. By the adoption of the technical scheme, the steel template
system is good in integrality, the templates do not deform easily, fixation is firm, the supporting beam is prevented from producing
structural deformation when concreted is poured, and
assembly and disassembly are rapid and convenient.
