Abstract:
1. A variable fastener for fixing a curtain wall, enabling a vertical member of a curtain wall unit to be coupled to an end portion of a building slab, the variable fastener comprising: a first bracket fixed to the end portion of the slab; and a second bracket, one side of which is coupled to the vertical member of the curtain wall unit, and the other side of which is coupled to the first bracket, so as to transfer the load of the curtain wall unit to the slab, wherein, the first bracket includes a base portion fixed to the end portion of the slab, and a support portion formed on a front end of the base portion so as to be higher than an upper surface of the base portion, and the second bracket includes a fixing portion fixed to the vertical member of the curtain wall unit, a height-adjusting bolt coupled perpendicularly along one side end of the fixing portion, the one side end being in the direction of the first bracket, and horizontally rotatable, a catching portion, one side of which is coupled to the height-adjusting bolt by a scheme of secreting a screw, and the other side of which is mounted on an upper part of the support portion, and a height-adjusting nut fastened to the height-adjusting bolt and integrally rotated with the height-adjusting bolt to adjust the height of the catching portion, wherein the support portion of the first bracket has a circular cross-section and a stick shape, and is separated from the upper surface of the base portion by a placing member, wherein in the second bracket, bolt-support portions, through which the height-adjusting bolt passes, are respectively formed in an upper portion and a lower portion of one side end portion of the fixing portion, the height-adjusting nut is fixed to an upper portion of the height-adjusting bolt passing through the bolt-support portion and is placed in an upper portion of the bolt-support portion to prevent the height-adjusting bolt from being separated, and a support-portion accommodation groove having a shape corresponding to the shape of the cross section of the support portion is formed in a lower portion of the other side of the catching portion so as to accommodate the support portion.
