Description

可供塔吊转换的共用基础及其施工方法 技术领域
本申请涉及建筑施工技术的领域，尤其是涉及一种可供塔吊转换的共用基础及其施工方法。
背景技术
大型体育场馆、会展场馆类建筑的结构形式一般为：主体结构采用钢筋混凝土的框架结构形式，局部采用劲性结构；屋盖结构采用钢桁架、网架等钢结构形式。在进行此类大型场馆建筑施工时，起重吊装设备的选择尤为重要，在不同的施工阶段需要选择不同的起重吊装设备。
在实际作业中，主体结构施工阶段多采用QTZ615型塔吊进行，QTZ615型塔吊的吊重较小，为轻型塔吊，以80米臂长为例，QTZ615型塔吊的最大吊装重量约26吨，末端吊装重量约3.5吨，主要适用于钢筋混凝土结构施工和劲性结构的钢杆和钢梁等小H型钢结构构件的吊装。屋盖钢结构施工阶段多采用QTZ1800型塔吊进行，QTZ1800型塔吊的吊重较大，为重型塔吊，以80米臂长为例，QTZ1800型塔吊的最大吊装重量约64吨，末端吊装重量约18吨，适用于较大型的钢结构构件吊装。
而为了实现不同塔吊在不同施工阶段的更换，现场需要制备两个独立的塔吊的预埋节和基础，一方面导致经济成本的增加，这是因为制作两个预埋节和基础需要花费更多数量的钢筋和混凝土等材料，另一方面，为了进行两个不同位置塔吊的安装，施工现场不得不预留更多的洞口，因此会降低施工质量，提高安全风险。
发明内容
为了改善现有技术中需要制备两个独立的塔吊的预埋节和基础来实现不同塔吊在不同施工阶段的更换的问题，本申请提供了一种可供塔吊转换的共用基础及其施工方法。
本申请提供的可供塔吊转换的共用基础及其施工方法采用如下的技术方案。
一种可供塔吊转换的共用基础的施工方法包括以下步骤：
S1：前期准备，根据施工需求确定并分析施工现场所需塔吊的规格；
S2：制备共用基础，将重型塔吊的预埋节作为主受力构件，所述预埋节上设置有用以与重型塔吊连接的第一地脚，在预埋节上加装用以与轻型塔吊连接的第二地脚；
S3：施工准备，开挖基坑，在基坑中安装马凳；
S4：安装共用基础，将预埋节与马凳连接，在此使第一地脚和第二地脚露出地面；
S5：固定共用基础，向基坑中浇筑混凝土。
在上述技术方案中，在制作共用基础前，先对施工需求进行分析，从而明确吊装需求，确定施工现场所需塔吊的规格，再对施工现场所需塔吊进行分析。在此之后，将重型塔吊的预埋节作为主受力构件，预埋节上设置有原有的用以与重型塔吊连接的第一地脚，随后将用以与轻型塔吊连接的第二地脚加装至预埋节上，第二地脚和预埋节共同构成共用基础。此时的共用基础既配设有第一地脚，也配设有第二地脚，即，共用基础既能与重型塔吊连接，也能与轻型塔吊连接。当共用基础制备完成之后，将共用基础运输至施工现场。再在施工现场开挖基坑，并在基坑中安装用以与预埋节连接的马凳。随后将预埋节与马凳连接，由此将预埋节安装于基坑中，此时使第一地脚和第二地脚露出地面。当预埋节的安装完成之后，向基坑中浇筑混凝土，待混凝土凝结之后，共用基础被固定于基坑中，此时第一地脚和第二地脚同样被固定并露出地面用以与塔吊进行连接。
上述过程中各部件配合可完成共用基础的施工，该共用基础适用于不同塔吊的转换，其能同时满足不同规格的塔吊安装。该共用基础利用原有重型塔吊的预埋节作为基础的受力构件，无需额外再制作新的预埋节，由此使得共用基础既能满足施工需求，又能节约制作成本。
可选的，所述马凳底部设置有多个支脚，所述多个支脚远离所述马凳的一端具有水平的弯折段；在步骤S3中，在基坑中安装马凳时，将支脚的弯折段与基坑贴合，校核马凳的水平度，确保马凳处于水平状态后在支脚处浇筑混凝土以形成垫层。

具体实施方式
以下结合附图1-8对本申请作进一步详细说明。
实施例1
本申请实施例1公开了一种可供塔吊转换的共用基础的施工方法，包括以下步骤：
S1：前期准备，根据施工需求确定并分析施工现场所需塔吊的规格；
S2：参照图1和图2，制备共用基础，将重型塔吊的预埋节1作为主受力构件，预埋节1上设置有用以与重型塔吊连接的第一地脚2，在预埋节1上加装用以与轻型塔吊连接的第二地脚3；
S3：施工准备，对共用基础进行放线，开挖基坑。
参照图3和图4，在基坑中安装多个马凳10，马凳10上开设有第一螺纹孔，马凳10底部设置有多个支脚19，支脚19由钢筋构成，多个支脚19远离马凳10的一端具有水平的弯折段20。
将支脚19的弯折段20与基坑贴合，校核马凳10的水平度，确保多个马凳10均处于水平状态后，在支脚19处浇筑混凝土以形成垫层21。
垫层21与马凳10之间存有空间，混凝土达到一定强度后(48小时为宜)，在垫层21与马凳10之间绑扎用于连接支脚19的底层钢筋22，底层钢筋22从马凳10与垫层21之间穿过，底层钢筋22通过马凳10下方时不允许将底层钢筋22切断。
S4：参照图1和图4，安装共用基础，预埋节1上螺纹连接有连接螺栓9，连接螺栓9与马凳10上的第一螺纹孔对接，将连接螺栓9拧进第一螺纹孔中以将预埋节1连 接于马凳10上，调整连接螺栓9来进行预埋节1的找正，确保预埋节1的垂直度误差小于1/1000。
第一地脚2和第二地脚3露出地面：
参照图5，在预埋节1上绑扎斜拉筋24，斜拉筋24上端焊接在预埋节1上，下端绑扎在底层钢筋22上，在预埋节1周侧绑扎面层钢筋25和拉结筋26；
校核预埋节1的水平度，测量第一地脚2和第二地脚3露出地面的高度。
S5：固定共用基础，向基坑中浇筑混凝土：
复核第一地脚2和第二地脚3露出地面的高度，确保其与浇筑前的测量值相同；
进行混凝土的养护。
在本申请实施例中，为了进一步提高第二地脚3位于预埋节1上时的稳定性，在第二地脚3上焊接固定杆23，并将固定杆23焊接至预埋节1上。
在本申请实施例中，当基坑开挖完成之后，需根据土质条件确定基坑四周的边坡做法。基坑底部土层需达到一定地基承载力，必要时可采取砂石换填、土体加固、桩基等加强技术措施。
本申请实施例1中可供塔吊转换的共用基础的施工方法的实施原理为：在制作共用基础前，先对施工需求进行分析，从而明确吊装需求，由此确定施工现场所需塔吊的规格，再对施工现场所需塔吊进行分析；在此之后，将重型塔吊的预埋节1作为主受力构件，预埋节1上设置有原有的用以与重型塔吊连接的第一地脚2，随后将用以与轻型塔吊连接的第二地脚3加装至预埋节1上，第二地脚3和预埋节1共同构成共用基础，此时的共用基础既配设有第一地脚2，也配设有第二地脚3，即，共用基础既能与重型塔吊连接，也能与轻型塔吊连接。当共用基础制备完成之后，将共用基础运输至施工现场，再在施工现场开挖基坑，并在基坑中安装用以与预埋节1连接的马凳10；随后将预埋节1与马凳10连接，由此将预埋节1安装于基坑中，此时第一地脚2和第二地脚3露出地面。当预埋节1的安装完成之后，向基坑中浇筑混凝土，待混凝土凝结之后，共用基础被固定于基坑中，此时第一地脚2和第二地脚3同样被固定并露出地面用以与塔吊连接。
上述过程中各部件配合可完成共用基础的施工，共用基础可供不同的塔吊进行转换，其能同时满足不同规格的塔吊安装，共用基础将原有的重型塔吊的预埋节1作为基础的受力构件，无需额外再制作新的预埋节1，由此使得共用基础既能满足施工需求，又能 节约制作成本。
实施例2
本申请实施例2公开的可供塔吊转换的共用基础应用于实施例1中的可供塔吊转换的共用基础的施工方法中。参照图1和图2，可供塔吊转换的共用基础包括用以埋设于基坑中的预埋节1，预埋节1顶部设置有多个第一地脚2和多个第二地脚3，第一地脚2用以与重型塔吊连接，第二地脚3用以与轻型塔吊连接，多个第一地脚2环绕设置，多个第二地脚3环绕设置于多个第一地脚2的内侧，预埋节1底部设置有用以与基坑连接的连接件。
参照图1和图6，预埋节1包括多个支撑杆4，每一支撑杆4上均设置有一个第一地脚2，多个支撑杆4环绕设置，相邻两支撑杆4之间设置有加强杆6，相邻两支撑杆4之间还设置有连接杆5。连接杆5端部与支撑杆4顶部固定，每一连接杆5上均设置有一个第二地脚3，每一第二地脚3上固定有一固定杆23。
参照图1和图6，连接杆5上交错设置有多个加固杆18，部分加固杆18同时与连接杆5和固定杆23固定连接，另一部分加固杆18同时与支撑杆4和固定杆23固定连接，由此通过加固杆18提高第二地脚3与连接杆5和支撑杆4的连接紧密性，进而提高第二地脚3在预埋节1上的稳定性。
参照图1和图6，支撑杆4、连接杆5、加强杆6、固定杆23以及加固杆18均选用为H型钢结构，制作简单且成本低。
参照图1和图6，支撑杆4上沿长度和宽度方向均设置有多个栓钉7。当预埋节1安装于基坑中后，需向基坑中浇筑混凝土，由此将预埋节1固定且埋设于基坑中，栓钉7用以增强支撑杆4与混凝土的结合能力，进而提高预埋节1在基坑中的稳定性。
参照图1和图3，支撑杆4底部固定有支板8，连接件包括多个螺纹连接于支板8上的连接螺栓9，基坑中设置有马凳10，马凳10上开设有多个第一螺纹孔，第一螺纹孔与连接螺栓9对应并能与连接螺栓9螺纹连接。
将预埋节1安装于基坑中时，预先在基坑中安装马凳10，然后将预埋节1置于基坑中，在此连接螺栓9与对应的第一螺纹孔对接，转动连接螺栓9以将连接螺栓9拧进第一螺纹孔中，由此将支板8固定于马凳10上，进而将预埋节1安装固定于基坑中。在转动连接螺栓9以进行支撑杆4的连接的过程中，还可进行预埋节1的找正，从而对预埋节1的垂直度进行控制。
参照图1和图3，在本申请实施例中，支板8上开设有透气孔11，通过透气孔11提高填充在支板8下方的混凝土的密实程度。
参照图1和图6，第一地脚2包括安装板12，安装板12固定于支撑杆4顶部，安装板12上垂直固定有连接板13，连接板13上开设有销孔15，连接板13两侧贴合有承托板14。承托板14底部与连接板13固定，顶部用以与塔吊抵接。将第一连接座与对应的塔吊连接时，将塔吊底端与承托板14抵接，此时塔吊上加工好的孔洞与连接板13上的销孔15对齐，将销轴同时穿过孔洞与销孔15，由此完成塔吊的连接。承托板14和连接板13的共同配合可提高塔吊与对应的地脚连接的稳定性。
参照图6和图7，第二地脚3包括第二连接座17，第二连接座17上开设有第二螺纹孔，第二螺纹孔用以与螺栓螺纹连接。通过第二连接座17与对应的塔吊连接时，使塔吊上加工好的螺纹孔与第二螺纹孔对齐，然后将螺栓同时穿过塔吊上的螺纹孔与第二螺纹孔，由此通过螺纹连接的方式完成塔吊与对应的地脚的连接。
在本申请实施例中，为了提高共用基础的整体强度，支撑杆4顶部通过焊接的方式与安装板12连接，底部通过焊接的方式与支板8连接，连接杆5两端通过焊接与两个支撑杆4连接，第二地脚3被焊接固定于连接杆5上，第二地脚3、连接杆5、支撑杆4以及加固杆18之间同样通过焊接的方式固定连接。
在本申请实施例中，根据施工现场所采用的大多数塔吊的结构，将第一地脚2和第二地脚3的数量设置为四个，四个第一地脚2之间的连线围成矩形框。在其他实施例中，第一地脚2和第二地脚3的数量和具体结构可更加实际施工的塔吊进行适用性调整。
在本申请实施例中，第一地脚2和第二地脚3的结构参考施工所需的QTZ1800型塔吊和QTZ615型塔吊进行设计。参照图6，QTZ615型塔吊标准节的尺寸为2300×2300×6000mm(长×宽×高)，其可通过第二地脚3安装于共用基础上。参照图8，QTZ1800型塔吊标准节尺寸为3200×3200×6000mm(长×宽×高)，其可通过第一地脚2安装于共用基础上。在其他实施例中，第一地脚2和第二地脚3的具体结构可根据实际施工中所选用的塔吊进行设计，第一地脚2和第二地脚3的结构可以相同也可不同。在其他实施例中，也可根据第一地脚2和第二地脚3的结构在对应的塔吊上加工所需的销孔15或螺纹孔，以使塔吊能与对应的地脚建立连接。
在本申请实施例中，共用基础安装于基坑中，当共用基础安装完成之后，需向基坑 中浇筑C35混凝土，由此将共用基础埋设于地下，此时第一地脚2和第二地脚3露出地面。而当共用基础安装于基坑中后，需根据塔吊型号、地基条件等因素在共用基础上配设钢筋，以提高共用基础位于基坑内时的稳定性。
本申请实施例2的可供塔吊转换的共用基础的实施原理为：使用共用基础时，通过连接件将预埋节1与基坑连接，由此将预埋节1安装于基坑中，随后向基坑中浇筑混凝土，由此将预埋节1埋设于基坑中，此时，预埋节1底部的第一地脚2和第二地脚3露出地面并用以与塔吊连接。待基坑中浇筑的混凝土凝结成型后，第一地脚2和第二地脚3即被固定，多个第一地脚2环绕设置且位于多个第二地脚3的外侧，第一地脚2可用以与重型塔吊进行连接，而多个第二地脚3则可用以与轻型塔吊进行连接，由此使得共用基础可供不同的塔吊进行转换，其能同时满足不同规格的塔吊安装。
以上均为本申请的较佳实施例，并非依此限制本申请的保护范围，故：凡依本申请的结构、形状、原理所做的等效变化，均应涵盖于本申请的保护范围之内。
