Description

基于BIM的薄壁槽钢组合房屋
技术领域
本发明涉及薄壁钢结构房屋组件技术领域,特别是涉及一种基于BIM的薄壁槽钢组合房屋。
背景技术
冷弯薄壁型钢结构建筑体系由于其自重轻,抗震性能好,连接形式多样,可适应复杂建筑造型,较少或无湿法作业,适宜工厂化优化设计及模块化生产,施工周期短,房屋格局布置灵活,建筑垃圾少,构件可重复使用,对环境的污染接近于零等的特点越来越受到人们的关注,并被列为底层和中高层建筑中的优选项目。
目前,对新型高强冷弯型钢尤其是薄壁冷弯型钢的开发及应用,成为冷弯型钢领域的新前沿。然而,我国在冷弯薄壁钢结构对产品构件的深加工不够,尚未达到广泛的零件化,模块化生产。习惯于采用外国成型技术,所开发的具有自主知识产权的结构体系少之又少,缺少自主品牌。随着近年来新农村建设的迅速发展,对新型结构的房屋需求不断增长,逐渐也改变了传统的观念,钢结构住房也逐渐在农村发展开来,现有的钢结构住房体系结构比较笨重,施工周期比较长,成本较高,不利于其推广应用,发明人在去年申请了薄壁钢结构单体型材和组合型材及其薄壁钢结构房的实用新型专利中提出了一种新型的钢结构住房体系,本专利申请就是为了配套解决上述专利的快速安装的问题。
专利公布号CN102359191A提供了“薄壁钢结构连接件及其连接结构”的专利技术,在该专利技术中,采用了连接件与薄壁钢型材之间通过箍紧钢带进行快速对接的方案。该方案适合短期快速组件薄壁钢结构房屋,结构设计合理,在无故障条件下强度较高。然而,上述专利技术在投入实施过程中存在型材结构复杂,制造难度大的问题,不能很好地与现有型材成型机相结合,需要专用成型设备,成本高,影响推广应用。在该专利技术中,将管状或槽状型材套装于连接件外侧,再利用连接件上的箍槽作为防脱落固定中心,用箍紧钢带将型材强制压缩在箍槽内。但在实际使用过程中,由于箍槽两侧翼板的边缘存在台阶和棱边,而薄壁钢型材的厚度非常薄,薄壁型钢厚度通常在0.3mm左右,被箍紧钢带压缩变形后的薄壁钢型材很容易破损,破损后导致型材强度明显降低,甚至会造成整个型材断裂,而且破损后形成的空洞无法进行防腐处理,雨水进入破损缝隙后造成连接结构受到腐蚀问题。所以以上专利技术在实际应用中存在安全隐患,有待于改进。
发明内容
本发明的目的是针对现有薄壁钢结构连接件和连接结构存在的问题和不足,提供一种基于BIM的薄壁槽钢组合房屋,可以避免连接结构局部受压力过大而受损问题,而且能够适合不同型钢连接需求以便降低加工难度和降低生产成本。

有益效果:本发明可将内翻边C型钢快速牢固对接,或者将组合方钢快速牢固对接。连接头设置有腹板,强度高,可作为标准连接件。内翻边C型钢为标准型钢,根据尺寸标准有五种型号内翻边C型钢,以适应不同结构强度要求。连接头内侧设置的让位孔与内翻边C型钢的内翻边相互扣合并被压缩在一起,达到内外嵌套效果。连接头外侧设置的定位槽可与内翻边C型钢凸凹相互嵌套在一起,再通过紧固钢带进行压缩固定后,达到固定且防滑脱效果。本发明结构简单合理,不会出现局部受挤压而破损问题,通过箍紧钢带可以达到简便、高效施工的目的,不需要焊接或铆接等工艺步骤,而且连接强度高,不易滑脱。连接件的部分腹板中部还可以设有匹配的减重孔,能够进一步的减轻该连接件的自重,从而能够减轻房屋的自重。
