Description

一种完全装配式混凝土板马凳筋 技术领域
本发明属于马凳筋领域，尤其是涉及一种完全装配式混凝土板马凳筋。
背景技术
随着我国建筑行业突飞猛进的发展，钢筋混凝土结构已经广泛运用于工程实际当中，钢筋在施工过程中起着非常重要的作用，被称为结构的“骨架”，直接影响结构的承载力、稳定性。在现浇钢筋混凝土板过程中需要将上部钢筋网片架空来实现混凝土均匀布满楼板，而且要承担浇筑时带来的冲击荷载和人群活荷载，这就要求钢筋网片的下部支撑要有足够强度且有较好的稳定性以保证施工过程中的安全问题。在施工过程中采取的措施通常是在上部结构钢筋网片下设置马凳筋(俗称“铁马”)，来承担上部荷载并保证结构的稳定性。马凳筋的形式有很多种，有“几”字形，板凳形，预制砼马凳等。但在施工过程中通常需要大量人力来安装马凳筋，且需要将其与下部钢筋网片通过绑扎，焊接等方式一起固定，这样会使用钢量增加，增加楼板自重，浪费资源严重且耗时耗力，更严重者会拖慢工程的整体施工进度，并不能很好的保证整体结构的稳定性且工作量较大。此外，安装质量并不能得到很好的保证，需要多层检验确保安全。近年来，树状结构受到工程设计人员的青睐，树状结构是一种复杂的空间刚架体系，具有力流明确,传力合理,造型优美,是一种集造型仿生和结构仿生为一体的仿生结构,可应用于大型游乐场所、文化场馆、机场建筑和候车站台等结构工程中。
发明内容
有鉴于此，本发明旨在提出一种完全装配式混凝土板马凳筋，以解决上述的不足之处。
为达到上述目的，本发明的技术方案是这样实现的：
一种完全装配式混凝土板马凳筋，包括主支撑腿、主连接头、分支撑腿和底座；
主支撑腿与分支撑腿之间通过主连接头连接，分支撑腿设有多个，分支撑腿底部与底座可拆卸连接，分支撑腿顶部与主连接头可拆卸连接，主支撑腿可拆卸设置于主连接头上端，多个分支撑腿的顶部连接同一个主连接头。
进一步的，分支撑腿包括第一分支撑腿、分连接头和第二分支撑腿；
主连接头底部设有用于安装第一分支撑腿的第一插槽；
第一分支撑腿与第二分支撑腿通过分连接头连接，分连接头上端设有用于插接第一分支撑腿的第一分支撑插槽，分连接头下端设有用于插接第二分支撑腿的第二分支撑插槽，第二分支撑腿设有多根。
进一步的，主连接头与分连接头结构一致。
进一步的，底座包括多个底板，底板的数量与分支撑腿数量对应，底板呈V形，每个底板上均设有用于插接第二分支撑腿的底座插槽。
进一步的，底座还包括连接块，两个相邻底板之间通过连接块可拆卸连接。
进一步的，连接块的两端向上翻折形成第一C形勾，连接块的中间位置设有限位连接块，底板的两端向下翻折形成与第一C形勾对应的第二C形勾，第一C形勾与第二C形勾配合连接。
进一步的，底板下表面还设有支撑脚。
相对于现有技术，本发明所述的一种完全装配式混凝土板马凳筋具有以下有益效果：
(1)本发明所述的一种完全装配式混凝土板马凳筋，卡头可以保证马 凳筋与上部钢筋网片连接牢固，使得钢筋不发生移动，保证了上部钢筋网片在施工期间的稳定性。
(2)本发明所述的一种完全装配式混凝土板马凳筋，所有部件均可在工厂通过制作模具预制完成，各部件尺寸确定以后可使用流水线生产来加快制作的进度，预制完成后可以进行简单的组装，将对应的连接杆与节点相连，运往现场后再与上部钢筋相连。
(3)本发明所述的一种完全装配式混凝土板马凳筋，受力合理，制作简单，易上手安装，完全实现了马凳筋的装配化施工，加快了施工进度且连接质量得到很好的保证；且对比采用焊接的方式连接的马凳筋，本申请即省时省力，而且更加经济，节省工程预算。本申请中的马凳筋整体采用PVC材料，制作模具后并加入流水线生产效率会大大提升。

下面将参考附图并结合实施例来详细说明本发明。
如图1至图3所示，一种完全装配式混凝土板马凳筋，此结构是经过通用有限元软件ANSYS找形优化后的状态，各杆件长度以及各节点的角度均可以精确得到；
一种完全装配式混凝土板马凳筋为树状结构马凳筋，这一结构提供了更好的稳定性，放置在混凝土板下部钢筋间距之间。
本申请中的马凳筋整体结构采用PVC材料，具有一定的弹性，可使得钢筋卡入所述凹槽的内部并不易滑出，但不仅限于PVC材料，材料若具有轻质、经济、环保、满足强度、便于生产等特点均可作为源材料。
如图1至图3所示，一种完全装配式混凝土板马凳筋，包括主支撑腿1、主连接头2、分支撑腿和底座3；
所述主支撑腿1的直径应小于混凝土板底部钢筋的间距，其高度等于混凝土板保护层的厚度。
主支撑腿1位于整个装置顶端，与上部钢筋网片某单根钢筋相连。
主支撑腿1与分支撑腿之间通过主连接头2连接，分支撑腿设有多个，分支撑腿底部与底座3可拆卸连接，分支撑腿顶部与主连接头2可拆卸连接，主支撑腿1可拆卸设置于主连接头2上端，多个分支撑腿的顶部连接同一个主连接头2。
分支撑腿包括第一分支撑腿4、分连接头5和第二分支撑腿6；
主连接头2底部设有用于安装第一分支撑腿4的第一插槽401；
第一分支撑腿4与第二分支撑腿6通过分连接头5连接，分连接头5上端设有用于插接第一分支撑腿4的第一分支撑插槽501，分连接头5下端设有用于插接第二分支撑腿6的第二分支撑插槽502，第二分支撑腿6设有多根；
需要明确的是，在实际使用中，受到压力等各种力的作用，会导致第一插槽401和第二分支撑插槽502的倾斜角度不同；
第一分支撑插槽501与第一分支撑腿4的直径一致，保证两者之间无空 隙，不发生相对移动；
第二分支撑插槽502与第二分支撑腿6的直径一致，保证两者之间无空隙，不发生相对移动；
第一分支撑腿4设有三根，第二分支撑腿6设有九根；
主连接头2与分连接头5结构一致，在实际生产与现场安装使用时，只需生产一种支撑头即可，节省了生产工厂的设计与制造成本，并且在安装使用时，主连接头2与分连接头5结构一致，无需挑选实用，加快了安装效率。
主连接头2与分连接头5结构一致。
底座3包括多个底板7，底板7的数量与分支撑腿数量对应，底板7呈V形，每个底板7上均设有用于插接第二分支撑腿6的底座插槽701。
底座插槽701的倾斜角度与第二分支撑腿6的倾斜角度一致。
底座3还包括连接块，两个相邻底板7之间通过连接块可拆卸连接。
连接块的两端向上翻折形成第一C形勾8，连接块的中间位置设有限位连接块801，底板7的两端向下翻折形成与第一C形勾8对应的第二C形勾，第一C形勾8与第二C形勾802配合连接。
底板7下表面还设有支撑脚9。
由于在施工时所遇到的荷载不一，这里提供两种调节马凳筋整体高度的方案：
方案一：当板厚较薄，且受到的侧向荷载较小时，可以通过调节马凳筋最上部主支撑腿1的高度或者是支撑脚9的高度来实现整体高度的调整。
方案二：当板厚较厚时，通过调节马凳筋最上部主支撑腿1的高度或者是支撑脚9的高度无法实现很好地支撑效果，原因是马凳筋受到的侧向荷载 较大时，如果采用方案一所述方法调节高度，整体稳定性会降低，当遇到较大的侧向荷载(如浇筑混凝土时)，会对主支撑腿1与上部钢筋连接处产生较大的弯矩，从而使得受力不合理。因此，当板厚较厚时，可以通过放大马凳筋整体比例的方式，解决板厚问题。这样可以即保证整体的稳定性，又可以承受浇筑混凝土时带来的较大的侧向荷载。
安装流程：
步骤1、根据混凝土板厚以及保护层的厚度确定树状结构马凳筋的高度。整体高度与各结构的尺寸大小等数值经过通用有限元软件ANSYS找形优化确定。
步骤2、各部件尺寸确定以后，在工厂制作模具，各部件均通过模具倒出。
步骤3、将树状结构马凳筋各部件在工厂进行预制。其中，为了制作方便将各连接杆的直径设置为相同值。将各连接杆统一制成一体的长杆，根据不同的长度需要，对长杆进行切割以获取所述第二分支撑腿6和第一分支撑腿4。
步骤4、将模具倒出的分连接头5、主连接头2上中间实体部分挖去，制成空心的套筒用于插接主支撑腿1、第一分支撑腿4和第二分支撑腿6。
步骤5、在制作所述底座3时，可将其通过模具制成一个带实心套筒的长板，此长板包括底板7以及支撑脚9，对实心套筒进行挖空处理制成底座插槽701，再对所述底板12进行切割，制成第二限位块802和连接块。
步骤6、将制成的各部分零部件进行组装。在组装过程中确保各部分连接紧密，不可滑出和脱落。
步骤7、将组装好的完全装配式马凳筋运往施工现场。
步骤8、将马凳筋顶部主支撑腿1与上部钢筋网片某单根钢筋固定。将马凳筋放在下部钢筋网片上。并检查各部件之间连接是否牢固，防止某部件发生脱落。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
