Joint structure for connecting slant supporter and square steel strut for temporary soil sheathing work

摘要

The present invention is for the connection structure of the inclined support material used in the temporary earthquake construction method used in urban excavation construction, in particular, provided with an inclined support material fastened to the coupling end of the support beam and the band made of square steel pipe, By forming fixing plates having fastening holes at both ends of the ash, and forming fastening screw holes at the side ends of the braces corresponding to the fastening holes, they are firmly fixed by separate fastening bolts. The use of the brace made of square steel pipe ensures uniform stiffness in the up, down and left and right directions, eliminating the need for reinforcement or adding work at all, making it easy to secure workability and shortening the construction period. In the construction of the inclined bracing material that is supported and coupled to the connection part, the installation of the inclined bracing material is achieved by simply tightening the bolts, so that it is possible to shorten the construction period with improved workability, and compared to the conventional bracing based on the same raw material cost required for the bracing It is very effective because the section modulus and the cross section secondary moment are superior, and it can serve as a safe passage for the worker through the brace made of square steel pipe, thereby providing better workability.
