Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building structures, and in particular relates to an assembled handrail node. Background Art
[0002] Railings can be seen everywhere in life, especially in public areas such as auditoriums and living rooms of civil buildings. The perfect combination of railings and decorations gives people a magnificent feeling. However, in real life scenes, due to the intersection of the installation of railings and the process sequence of decorative finishes, it will cause defects in the decorative effect, greatly reducing the effect and quality of the finished product.
[0003] At present, the construction of railing handrails is divided into two types. One is to lay tiles first and then make railing handrails. In this case, since the decorative surface has been completed, it is necessary to verify the size on site. Most of the time, the materials are cut and welded on site, which causes secondary damage to the finished product on site, and welding sparks fly, and secondary chiseling damages the finished decorative surface. The second is to install the railings first and then paste the decorative panels, which will cause defects in the finished surface. The decorative panels are cut into small pieces and pasted behind the railings, affecting the decorative surface effect. Utility Model Content
