地下连续墙H型钢接头整体焊接模具
本技术涉及建筑机械设备领域,具体是一种地下连续墙H型钢接头整体焊接模具。
技术介绍
地下连续墙是基础工程,在地面上采用一种挖槽机械,沿着深开挖工程的周边轴线,在泥浆护壁条件下,开挖出一条狭长的深槽,清槽刷壁后,在槽内吊放钢筋笼,然后用导管法灌筑水下混凝土筑成一个单元槽段,如此逐段进行,在地下筑成一道连续的钢筋混凝土墙壁,作为截水、防渗、承重、挡水结构。地下连续墙常采用钢筋混凝土结构,接缝处搭接接头采用H型钢接头,作用是防止基坑外侧水和流砂从接缝处流进基坑内。然而横向的H型钢需要整体焊接,体积和重量都非常大,焊接起来很不方便,普通的焊接夹具设计复杂,操作不便,且无法固定好H型钢,从而导致焊接效率低下。
技术实现思路
本技术为了解决现有地下连续墙H型钢接头在整体焊接时不方便、现有焊接夹具结构复杂、操作不便等问题,提供一种地下连续墙H型钢接头整体焊接模具。本技术是采用如下技术方案实现的:地下连续墙H型钢接头整体焊接模具,包括两个尺寸相同且截面呈“凹”字形的托架和压板,托架和压板的凹面相互对应,以形成H型钢的容置腔,托架和压板的相对面通过若干 ...
