Steel bridge expansion joint installation and construction method
The invention relates to a steel bridge expansion joint installation construction method. The method comprises the following steps that firstly, welding treatment is conducted, wherein steel bars on an expansion joint and steel bars on the end face of a bridge are welded together through strip-shaped steel bars; 2, concrete filling, wherein the connecting positions of the steel bars on the expansion joint and the steel bars on the end face of the bridge are filled with concrete; 3, surface trowelling is conducted, specifically, the surface of the concrete is trowelled before the concrete is solidified, so that the surface of the concrete is in a horizontal state; and 4, mounting a cover plate: after the concrete is solidified, mounting the cover plate for protecting the concrete on the end face of the bridge. When the concrete surface is trowelled, the steel bridge expansion joint installation construction device horizontally moves at a constant speed on the upper surface of the expansion joint and the upper surface of the bridge in the length direction of the expansion joint, the concrete surface is trowelled through the troweling mechanism in the moving process, efficiency is improved, and it is guaranteed that all positions of the concrete surface are flush.
本发明涉及一种钢质桥梁伸缩缝安装施工方法，包括以下步骤：步骤一、焊接处理：通过条形钢筋将伸缩缝上的钢筋和桥梁端面上的钢筋焊接在一起；步骤二、填混凝土：用混凝土对伸缩缝上的钢筋和桥梁端面上的钢筋连接位置进行填实；步骤三、表面抹平：在混凝土凝固前将混凝土表面抹平，使得混凝土表面呈水平状态；步骤四、安装盖板：待混凝土凝固后，在桥梁端面上安装用以保护混凝土的盖板。本发明对混凝土表面进行抹平处理时，钢质桥梁伸缩缝安装施工装置在伸缩缝上表面和桥梁上表面沿着伸缩缝长度方向水平匀速移动，移动过程中通过抹平机构对混凝土表面进行抹平，提高了效率且保证了混凝土表面各处平齐。
