Bending Type Wire Fixing Block and the Reinforcing Method of RC Girders using thereof

摘要

The invention existing RC Beams in the most widely used construction methods of reinforced concrete (RC) Division in Korea will reinforce the lack of strength or of the bending-type steel fixing block for elastic strength of RC beams strengthened. RC reinforcement is required in most cases the beam is a conventional steel or carbon geotinde due to the lack of Bending The reinforcement method using a fiber reinforcement, etc. are to be attached to a separate case on the side of the beam, when you try to compensate for Bending and shear strength at the same time. In addition, it is impossible to undoing the deflection of the beam has already occurred due to a lack Bending. Steel reinforcement and strength at the same time presented in Figs. 2 and 3 with a reinforced how to restore the deflection of the beam has already occurred to undo tension wire method (wire tensioning) has. bowed wire fixing block of the invention is an improvement over the threshold of Figure 3. The Figure 2 method. Because symmetrically reinforcement in the beam depends upon the size of the reinforcing strength to 2, 4, and 6 may settle the steel wire (Fig. 4). Typically the reinforcing effect corresponding to the 6-HD-25 using 6-wire reinforced with steel 12.7 standard that is widely used in the reinforcement of the steel tension ways, and if you need more reinforcement steel 15.2 (1 seondang tensile strength 15tf) 6 may be used to achieve the effect corresponding to the maximum 9-HD-25 reinforced. bowed long steel wire fixing block decoration RC Beam Deflection of reinforcing the existing advantages of this method of the present invention as described above, to restore the original state was to improve the ability to reduce or eliminate the crack width than the previous invention by the applicant. In addition, as well as to increase the shear reinforcement effect completely against the position of the block settled by bending downward in the direction of the steel beam ends to be superior in aesthetic and anti-worker up under the narrow beam makes it possible to perform the wire tension work There is also the effect of improving the workability of the space. ;
