Apparatus for reinforcing resistance load force installed to the steel member of bridge to introduce prestressing to the steel member step by step for increasing resistance load force of steel bridge and method for reinforcing resistance load force using the apparatus

摘要

The present invention step by step relates to a load carrying capacity reinforcement method using an installation for introduction peuriseuteuresing the steel load carrying capacity reinforcement device and this end, the lower both sides of the simple beam of the bridge steel with I-beam or H-beam steel portion to the load carrying capacity increase of the steel bridge the primary installation the tension bracket and the load carrying capacity of the reinforcing device after inserting a strand in the main tensile tension fixing bracket by using the anchorage, and install the supplemental tension bracket on both sides of the steel center, and fixing the tension strand and; Tension fixes the fixing strand to the main bracket tensile load carrying capacity of these reinforcing device, and the next step is a load carrying capacity reinforcement method for fixing the seal to the auxiliary fixing strand tension bracket.; In another embodiment, installation tension bracket state to the lower both sides of the continuous bridge bridges steel with I-beam or H-beam steel, and to install the DB initiator in the upper central portion of the steel material, the birds on either side of the steel material lower center the insert through the strand tension in the main bracket of one side after installing and mounting the saddle and after passing through the radiator and DB I load carrying capacity reinforcement device for fixing the tension strand and the other side of the main tension bracket; To tension fixes the strand fixed on the main bracket of the tensile load carrying capacity of these reinforcing device.; The load carrying capacity reinforcement method is a method of separating a multi-level tensile strength loss than to introduce a tensile force at a time hameuroseo introducing tension to the steel also be reduced so that while the load is distributed to each of the anchorage.
