地下室外墙无对拉螺栓超高模板体系设计与施工

Design and Construction of No-tension Bolt Super-high Template System for Exterior Wall of Basement

地下室外墙质量的好坏主要取决于施工队伍的经验和素质。如何做到地下室外墙质量的稳定和可控,减少因施工队伍的不同而导致的质量变化,一直是一个有待探讨的课题。现以虹源盛世国际文化城项目地下室外墙为例,介绍其利用型钢与叠合双钢管作为模板的龙骨,很好地解决了地下室外墙无对拉螺栓超高模板单侧支模的难题,同时保证了地下室外墙的防水质量。采用该法施工的地下室外墙各项质量指标均达到设计要求,为类似地下室外墙施工开辟了新的思路。

The quality of basement exterior wall mainly depends on the experience and the quality of construction team. How to stabilize and control the quality of basement exterior wall, and to decrease the different construction teams leading to the quality change is always a subject to further study. Taking the basement exterior wall of Hongyuan Shengshi International Cultural City Project as an example, the article introduces the use of section steel and composite double steel pipe as the keel of template, which solves the difficulty of unilateral formwork of no-tension bolt super-high template for exterior wall of basement well, and also guarantees the waterproof quality of basement exterior wall. Various quality indexes of basement exterior wall constructed by this method can reach the design requirements, which can provide the new idea for the construction of the similar exterior walls of basements.
