The invention relates to a new large section square column supporting system and method, which is mainly composed of a column template, a prefabricated wooden box, a sealing edge square wood, a column back edge and a reinforced bar hook. The upper and lower ends of the column template are each supplementation with a side block; the prefabricated wooden box is spliced by three sides of the ordinary formwork, and the internal interval is about 450mm to set up a template separation support, and is assembled by a self tapping screw and a gasket and a column template. The steel hook is across the precast wooden box, away from the top 200mm of the column template and bent up in the middle part of the reinforcing bar. The invention is different from the common square column formwork system and provides the construction method, that is to draw the detailed drawing of the square column according to the design scheme, the column template, the prefabricated wooden box and the back of the column in the prefabricated large cross section template system of the site processing site. After the bar binding is completed and the acceptance of the large section square column is completed, the large section of the prefabricated section will be prefabricated. The square pillar template is suspended to the square column position and accurate positioning, and the square column outside the square column is set up according to the requirement, and the concrete pouring with large cross section is strictly divided according to the standard to guarantee the quality of concrete pouring. The setting of the square column in the large section should be determined by calculation to determine the safety and stability of the reinforcement of the square column; when the concrete maintenance of the large section column has reached the design After strength, the template is dismantled and the large section square column formwork system is hoisted to the designated area. The surface floating of the square column template is cleaned according to the requirement, and the template isolating agent is painted in time to ensure the normal turnover of the template.

一种新型大截面方柱支模体系及方法
本专利技术涉及建筑结构中的模板工程施工领域,具体地说涉及一种新型大截面方柱支模体系及方法。
技术介绍
随着建设工程规模的扩大,墙柱等竖向构件的规格及施工难度均不断的提高,尤其是大型公建及多层地下室项目中,往往大面积或局部存在截面较大的方形框架柱,必须改进传统的木模施工工艺以保证方柱的成型效果。传统的方柱支模方法通常采用单层模板外侧设置竖向内愣方木(或方管等)辅以水平外楞的加固方式,常规的施工方法存在以下问题:柱模拼缝质量参差不齐、拼缝痕迹明显,容易导致漏浆;当方柱截面较大、层高较高时,砼浇筑过程中对侧模侧边压力大,容易涨模;方柱支模时,固定内楞方木的钉帽不可避免在方柱模板内侧,拆模后柱表面残留帽印,影响观感;方柱模板的安装与拆除耗费工时多;周转材料重复利用率低,模板损耗量较大。往往建设项目参建各方与行业部门对方形框架柱的观感质量要求很高,因此,改进传统的大截面方柱支模工艺并规范其施工方法尤为重要,有效提升方柱的施工质量。
技术实现思路
针对传统施工方法存在的不足,本专利技术提供了一种新型大截面方柱支模体系及方法,有效解决了大截面方柱容易涨模、模板拼缝痕迹明显、观感质量较差、周转材料损耗量较大等问题,不仅保证了大截面方柱的外观质量,同时,可集中化加工制作大截面支模面板,大大减少了人工配模成本,加大了周转材料的重复利用率。为实现上述目的,本专利技术采用的技术方案是:一种新型大截面方柱支模体系,主要由柱模板、预制木盒、封边方木、柱背楞和钢筋吊钩组成;所述的柱模板上下端各补设一封边道方木,增加其端部抗压能力,防止混凝土漏浆;所述的预制 ...
