Type reinforcement device.
Description
The present invention relates to a device for preventing buckling and deformation of webs and flanges of H-beams by reinforcing H-beams, and more particularly, to an apparatus for preventing buckling and deformation of webs and flanges of H-beams by including reinforcing bodies and wedges, And 2 flanges, so that the web and the flange of the H-shaped steel are reinforced, thereby effectively preventing the occurrence of buckling and deformation in the web and the flange of the H-shaped steel, The present invention relates to a T-type reinforcement device for preventing buckling and deformation of an H-shaped steel, which can reduce the cost and time required for reinforcement.
(A direction orthogonal to the longitudinal direction in which the H-shaped steel extends, in the same direction as the direction in which the web is disposed and extended) of the H-shaped steel is applied to the H-shaped steel composed of the first and second flanges and the web, When acting, the web is subjected to a large compressive force at the point where the load is concentrated, thereby causing buckling or other deformation of the web. Deformation may occur not only in the web but also in the flange.
Particularly, when the H-shaped steel is used as a wale of the temporary earth retaining structure, a large compressive load is concentrated on the web and the flange of the H-shaped steel at the position where the ends of the strut braids arranged in the lateral direction are engaged with each other, Buckling, and other deformation of the web and flange. In addition to the case where the H-shaped steel is used as a wale, the possibility of deformation due to the action of the concentrated load as described above also increases when the steel wire of the anchor body inserted and fixed in the ground is fixed.
Conventionally, a method of welding a plate-shaped reinforcing rib between the first and second flanges of the H-shaped portion in a portion in which loads are concentrated is used. In this case, since the reinforcing rib must be precisely cut and installed, it is not only troublesome to manufacture but also it is not easy to weld in a narrow space. Further, the flange and the web of the H-shaped steel, There is a disadvantage that it is not easy to remove the reinforcing rib again when the H-shaped steel is recycled.
As another conventional technique for reinforcing the H-shaped steel, a method of installing a stiffener having a construction capable of expansion and contraction by screwing is proposed in Korean Patent Registration No. 10-0259394 and Korean Patent Registration No. 10-0982650. However, in the case of a conventional reinforcing member having an elongated and contracted structure by screwing, in order to move the screw moving member which is screwed and expanded / contracted, it is necessary to rotate by using a separate rotary jig device, so that installation work is very troublesome, It is not easy to extend the reinforcement completely. In addition, it is very difficult to rotate the threaded portion due to corrosion or foreign matter in the threaded portion in a situation where the threaded portion is installed for a long period of time outdoors, so that it is difficult to shake after use, If the screw shape of the threaded joint portion is damaged, it is impossible to reuse the stiffener after demolition. Furthermore, in the case of the prior art, since the reinforcing member is formed by assembling a plurality of members such as a main body having a threaded portion, a screw moving member which is screwed to the screwed member, and the like, the assembly is cumbersome and costly.
The present invention has been developed in order to overcome the disadvantages and problems of the prior art as described above. It is installed between the first and second flanges of the H-shaped steel to effectively prevent buckling of the web and other deformation of the web and the flange, It is an object of the present invention to provide a method and structure for reinforcing an H-shaped steel by using a new reinforcing device which can be easily removed even after being installed outdoors for a long time and can be recycled even after being demolished.
The present invention also aims at providing a method and structure for reinforcing H-beams by using a new reinforcing device which has a simple structure and can be manufactured quickly and easily at a low cost and is easy to handle, install and dismantle.
In order to achieve the above object, according to the present invention, there is provided a stiffener including a reinforcing main body and a wedge; The reinforcing main body is provided between the first and second flanges of the H-shaped steel in a vertical direction in parallel with the web and the other end surface is provided with a support shaft composed of a downward inclined surface so as to fit the wedge, And a pedestal for supporting the support shaft to prevent the position of the support shaft from being changed; The wedge is stuck in the gap between the other end of the support shaft and the first flange and the support shaft is fixed between the first and second flanges in a state in which one end of the support shaft is in tight contact with the second flange of the H- There is provided a T-shaped reinforcement device for preventing buckling and deformation of an H-shaped steel, characterized in that the support shaft supports a compressive force applied to the H-shaped steel.
In the T-shaped reinforcement device of the present invention as described above, the inner end portion of the pedestal is integrally coupled to the middle of the support shaft so that the reinforcing main body may have the letter T shape. Alternatively, the plurality of support axes may be spaced apart in the longitudinal direction And a plurality of support shafts are integrally formed by the connecting rods, and the pedestal is integrally coupled to the connecting rods so as to be orthogonal to each other, so that the reinforcing main body is formed It is possible.
In the T-shaped reinforcement device of the present invention described above, a guide plate for guiding the wedge to be inserted into the gap between the other end of the support shaft and the first flange without moving in the longitudinal direction is provided on the longitudinal side surface at the other end of the support shaft When the wedge is stuck between the other end surface of the support shaft and the first flange, the wedge fixing portion is supported by the support shaft and the wedge fixing portion, Are arranged side by side in the deployed position; The wedge fixing part is disposed in parallel with the supporting shaft so as to be juxtaposed to the supporting shaft so that the coupling member capable of disassembling and removing is fastened between the wedge fixing part and the supporting shaft so that the wedge fixing part and the supporting shaft are temporarily integrated with each other have.
According to the present invention, since the support shaft is disposed between the first and second flanges of the H-shaped steel, a compressive force acts on the first flange and the web due to a flexural load acting on the H-shaped steel or a load acting on the H- It is possible to effectively reduce the buckling of the web and the deformation of the web and the flange, thereby greatly reducing the compressive force acting on the web of the H-shaped steel and the stress acting on the flange, .
In particular, when the T-shaped reinforcement device of the present invention is installed for the reinforcement of the H-shaped steel, no welding is required at all, and there is no fear of deformation of the H-shaped steel due to welding. It is necessary to use only a hammer or a corresponding hammer for striking a wedge, so that there is no need for a particularly complicated or difficult-to-prepare tool, and the installation work can be performed very easily.
Further, since the T-type reinforcement device of the present invention can be easily removed and no damage is caused to deteriorate the function of the T-shaped reinforcement device and the H-shaped steel during the demolition process, the demolished T-type reinforcement device and the H- There is an advantage that it can be reused.
Also, the T-type reinforcement device of the present invention has an advantage that it can be easily removed and reused at any time regardless of the time period even if it is installed outdoors for a long time.
In addition, since the T-shaped reinforcement device of the present invention has a very simple structure, it can be easily and quickly manufactured at low cost, and it is possible to further reinforce the H-shaped steel by installing a large number of the H- .
