CN110593484A 一种H型钢及其加强板 无效 - 驳回

一种H型钢及其加强板
摘要：
本发明涉及一种H型钢及其加强板，H型钢加强板包括两条水平焊接边和一条竖直焊接边，两条水平焊接边分别用于与H型钢的上翼缘板、下翼缘板焊接，竖直焊接边用于与H型钢的腹板焊接；所述H型钢加强板的两水平焊接边与竖直焊接边之间均设有避让缺口，所述避让缺口为向H型钢加强板内凹的弧形缺口，弧形缺口用于避免H型钢加强板与腹板之间、H型钢加强板与相应翼缘板之间的焊缝交汇，弧形缺口能更好的通过变形消化H型钢焊接后的残余热应力，使H型钢加强板与翼缘板及腹板的焊接应力分散更均匀；设置弧形缺口的H型钢加强板能为焊枪提供更大的焊接空间，方便H型钢加强板与翼缘板及腹板的焊接。
摘要（英）：

The invention relates to H-shaped steel and a reinforcing plate of the H-shaped steel. The reinforcing plate of the H-shaped steel comprises two horizontal welding edges and a vertical welding edge. The two horizontal welding edges are correspondingly used for being welded to an upper flange plate and a lower flange plate of the H-shaped steel, and the vertical welding edge is used for being welded to a web of the H-shaped steel. Avoidance notches are formed between the two horizontal welding edges and the vertical welding edge of the reinforcing plate of the H-shaped steel. Each avoidance notch is an arc-shaped notch recessed towards the interior of the reinforcing plate of the H-shaped steel, and the arc-shaped notches are used for avoiding weld joint between the reinforcing plate of theH-shaped steel and the web and between the reinforcing plate of the H-shaped steel and the corresponding flange plates. The arc-shaped notches can better disperse residual thermal stress after H-shaped steel welding through deformation, so that the welding stress of the reinforcing plate of the H-shaped steel and the flange plates and the web are dispersed more uniformly; and the reinforcing plate of the H-shaped steel with the arc-shaped notches can provide a larger welding space for a welding gun, and welding of the reinforcing plate of the H-shaped steel and the flange plates and the web is facilitated.
