The invention relates to a pay-off hole protection structure in constructional engineering. The pay-off hole protection structure comprises a jacking and supporting assembly used for being jacked and supported in a pay-off hole. And the cover plate assembly is mounted on the jacking assembly and partially arranged on the floor plate, and the pay-off hole is opened or closed by opening or closing the cover plate assembly. And the abutting plates are installed at the two ends of the jacking assembly and are vertically arranged, and the abutting plates abut against the inner wall of the pay-off hole. The abutting plate comprises a vertical part and a transverse part, wherein the vertical part is vertically arranged and abuts against the inner wall of the pay-off hole, and the transverse part is perpendicularly connected to the top face of the vertical part and arranged on the floor plate. The length of the jacking assembly is adjustable, and the abutting plate tightly abuts against the inner wall of the pay-off hole by adjusting the length of the jacking assembly. According to the invention, it can be ensured that the cover plate assembly is installed at the pay-off hole more firmly and stably, and the problem that the cover plate assembly shifts due to collision is avoided.

本发明涉及一种建筑工程中放线孔防护结构，包括：供顶撑于所述放线孔内的顶撑组件；安装于所述顶撑组件上且部分置于所述楼层板之上的盖板组件，通过打开或关闭所述盖板组件以敞开或封闭所述放线孔。安装于所述顶撑组件两端且呈竖向设置的抵靠板，所述抵靠板抵靠于所述放线孔的内壁。所述抵靠板包括呈竖向设置且抵靠于所述放线孔内壁的竖向部以及垂直连接于所述竖向部顶面的横向部，所述横向部置于所述楼层板之上。所述顶撑组件长度可调，通过调节所述顶撑组件的长度以使所述抵靠板紧抵于所述放线孔的内壁。本发明可确保盖板组件更加牢固和稳定的安装于放线孔处，避免盖板组件因碰撞而产生移位的问题。
