[0026] Please refer to Figures 1-4 The utility model discloses an alloy handrail for glass railing with curved arc embodiment, alloy handrail for glass railing with curved arc includes spliced connection multiple alloy section bars 100 and multiple connection columns 200 and multiple connection steel sheets 300. In which alloy section bar 100 is aluminum alloy section bar 100. With the side of toughened glass 500 as the outside, the outside of alloy section bar 100 has the clamping groove 140 for clamping glass railing with opening downward, and the inside is provided with cavity 130, at the connecting end position of two adjacent alloy section bars 100, connection column 200 is quadrilateral column, and the two sides of the long side of connection column 200 are respectively abutted with the opposite surface of two alloy section bars 100, and the top surface of connection column 200 is provided with connection steel sheet 300 above and below the bottom surface respectively, and screw 400 fixes connection steel sheet 300 to two adjacent alloy section bars 100, so that two adjacent alloy section bars 100 are connected into an integral whole, and stainless steel self-tapping screw 400 is selected for screw 400. Alloy section bar 100 includes straight line or curved arc. The top end and the bottom end of connection column 200 are limited and fixed using connection steel sheet 300, which can effectively prevent connection column 200 from falling off between the gaps of alloy section bar 100, ensure the integrity of the whole handrail, and help to prolong the service life of the handrail.

[0027] The clamping of the clamping groove 140 enables the alloy profile 100 to be fixed to the edge of the tempered glass 500, and the alloy profile 100 is generally fixed to the top edge of the tempered glass 500. The closed cavity alloy profile 100 enables the processability of the railing handrail. The handrail is divided into multiple sections, including linear alloy profiles 100 and curved alloy profiles 100. The closed cavity curved alloy profile 100 is directly drawn to the required curvature, which converts the traditional handrail profile structure into a conventional drawable profile structure, thereby reducing the cost waste caused by processing. At the connecting end of the alloy profile 100, the connecting column 200 fills the gap between the two alloy profiles 100, and the connecting steel plate 300 connects the alloy profiles 100 so that the handrail can be spliced into a whole, facilitating on-site installation.

[0028] Referring to Figure 2 and Figure 4 , the tempered glass 500 is clamped into the clamping groove 140, and a sealing strip 600 is arranged between the tempered glass 500 and the side wall of the clamping groove 140 to prevent direct contact between the surface of the tempered glass 500 and the alloy profile 100.

[0029] Referring to Figure 5 and Figure 6 , in an embodiment, the alloy profile 100 includes a profile body 110 and a movable cover plate 120, the profile body 110 is provided with a top cavity 1301 at the top layer of the cavity 130 and a bottom cavity 1302 at the bottom layer of the cavity 130, and at one end of the profile body 110 connected to the connecting column 200, an opening is provided on the bottom surface of the bottom cavity 1302, and the movable cover plate 120 covers the opening and is detachably connected to the profile body 110; the connecting steel plate 300 at the bottom end of the connecting column 200 is fixed in the bottom cavity 1302 and above the movable cover plate 120. On the bottom surface of the alloy profile 100, the alloy profile 100 is snap-connected with the movable cover plate 120, and the snap-connection enables the movable cover plate 120 to be easily and conveniently closed, facilitating the construction of workers and helping to shorten the construction period. The bottom surface of the movable cover plate 120 is flush with the bottom surface of the alloy profile 100, ensuring the smoothness of the surface of the handrail, facilitating the cleaning in the later stage, and enhancing the aesthetic appearance of the surface of the handrail.

[0030] Referring to Figure 3 , in an embodiment, weather-resistant sealant 700 is filled in the gap position between the connecting column 200 periphery and the two alloy profiles 100 at the splicing position of the two adjacent alloy profiles 100. The weather-resistant sealant 700 is a silicone weather-resistant sealant 700, which has good sealing effect and weather resistance. When installing, the gap between the linear alloy profile 100 and the curved alloy profile 100 is filled with the connecting column 200 and the weather-resistant sealant 700, thereby enhancing the firmness of the connection between the two alloy profiles 100.

[0031] Referring toFigure 3 In an embodiment, the connecting column 200 comprises an aluminum column 210 and a galvanized steel column 220 sleeved in the aluminum column 210. The galvanized steel column 220 fills the hollow cavity of the aluminum column 210, so that the connecting steel plate 300 can be prevented from deforming and the integrity of the handrail connection can be ensured when the connecting steel plate 300 is subjected to a heavy blow at a position above the center of the aluminum column 210.

[0032] Reference Figure 5 In an embodiment, the top cavity 1301 and the bottom cavity 1302 are connected, and a reinforcing rib is arranged in the top cavity 1301 in the length direction of the alloy profile 100. The reinforcing rib divides the top cavity 1301 into a first chamber and a second chamber. The tips of the screws 400 for fixing the connecting steel plate 300 are accommodated in the first chamber or the second chamber. In the embodiment, the two ends of the connecting steel plate 300 are fixed by using at least two screws 400, and the tips of the two screws 400 are accommodated in the first chamber and the second chamber, respectively. The reasonable arrangement of the positions of the screws 400 increases the stability of the fixing of the connecting steel plate 300 and the connection of the alloy profile 100. The simple double-cavity structure of the cavity 130 facilitates the processing of the alloy profile 100. The reinforcing rib can disperse the force acting on the top of the cavity 130 of the body of the alloy profile 100, enhance the load-bearing capacity above the handrail, and reduce the risk of deformation of the cavity 130 of the alloy profile 100.

[0033] In an embodiment, the connecting steel plate 300 is a galvanized steel plate. The surface of the steel plate is subjected to a galvanizing treatment, which can effectively reduce the generation of oxidation rust and help prolong the service life of the connecting steel plate 300.
