Movable and convenient hogging moment tensioning equipment

Abstract

The invention discloses movable and convenient hogging moment tensioning equipment, and relates to the field of engineering construction. The movable and convenient hogging moment tensioning equipment comprises a supporting mechanism, the top end of the supporting mechanism is movably connected with a moving mechanism, the end, away from the supporting mechanism, of the moving mechanism is fixedly connected with a hanging mechanism, the bottom end of the supporting mechanism is provided with a fixed supporting mechanism, the fixed supporting mechanism is fixedly connected with the side wall of the bottom end of the supporting mechanism, the top end of the fixed supporting mechanism is movably connected with a tensioning mechanism, the supporting mechanism comprises a base table, a moving groove is formed in the top end of the base table, an embedded plate is arranged at the bottom end of the base table, a tensioning rib is fixedly connected with the front end of the embedded plate, and the bottom end of the moving mechanism is fixedly connected with a movable connecting bracket. When the equipment is used, a heavy jack can be hoisted to the position needing to be tensioned in a more labor-saving mode to conduct hogging moment tensioning by arranging a position-adjustable suspension type suspension mechanism, the wasted lifting and calibration time is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a movable and portable negative moment tensioning equipment. Background technique [0002] Negative bending moment refers to negative moment tendons. The steel bars set up to resist negative bending moments in reinforced concrete members of construction projects are called negative moment tendons. They are often referred to as "negative tendons" in engineering, and are generally used in two parts: Beam support reinforcement and slab negative bending reinforcement. Tensile: Refers to prestressed tension, adding tension in the component in advance, so that the prestressed tensioned component bears compressive stress, and then causes it to produce a certain deformation to cope with the load on the structure itself. Before the engineering structural components are subjected to external loads, pre-tensioning stress is applied to the steel strands in the tension module to impro...

Problems solved by technology

[0003] In the prior art, most of the negative bending moment tensioning process of the bridge deck still uses lifting equipment to lower the jack for tensioning, and manually move the jack to the tensioning position. The weight of the jack is very high, and there is inconvenience during the installation process. The installation position of the jack is not accurate, the time is long, etc.
