Scope

Scope: The scope of application is determined based on national and industry standards, and verified through actual working conditions. This collection of drawings is applicable to the cast-in-place construction of cantilever beams for continuous beam bridges and continuous rigid frame bridges. The drawings do not elaborate on formwork systems, which include external formwork, internal formwork, bottom formwork, and material specifications. Main Technical Content: This collection of drawings includes: preparation notes, total assembly drawings of the launching basket, drawings of various systems of the launching basket, and reserved 40Cr steel. Designers should refer to the preparation notes of the collection of drawings with the number T/SDCEAS30003—2022 to meet the construction requirements under specific working conditions. The triangular launching basket can meet the structural requirements of single-box single-chamber, single-box multi-chamber, and end-chamber structures in railway, highway, and municipal engineering projects. It is necessary to design and fabricate according to the launching basket components as a standard, to avoid current requirements. It should comply with the current national standards "High-Quality Carbon Structural Steel" GB/T 699 and "Carbon Structural Steel: Holes Arrangement on Uncoated Steel Surfaces and Steel Surfaces After Complete Removal of Existing Coatings, Component Selection Rules, Detailed Drawings of Main Components, Construction Key Points, and Appendixes". The drawings cover the cast-in-place construction of continuous beams in rooms. The triangular launching basket involved in this collection of drawings belongs to temporary structures. Structural collisions may occur during actual installation and construction on the construction site, affecting the construction. The steel used in the launching basket structure is of triangular structure, which is simple, robust, and stable. When using other grades of steel, it should
