Description

说明书 组合式塔基 技术领域
本发明涉及一种建设施工用具， 尤其是一种塔吊基础， 具体地说是一种可在现场快速 拼接且可重复利用的组合式塔基。
背景技术
众所击知， 塔吊是建筑施工中必不可少的设备， 为了防止塔吊承载后的倾覆， 必须对 塔基进行加固， 因此传统的施工现场必须用钢筋混凝土浇筑坚固的基础， 然后再将塔吊的 底架固定在地基上， 施工结束后， 这种地基将被拆除或覆盖， 因此， 这种地基成本大， 制 造周期长， 如果拆除还需要浪费大量的人力物力， 因此， 设计一种可在现场快速装拆且可 反复使用的稳定性好的组合式塔基是降低建筑成本， 缩短塔吊安装时间的关键。
目前， 现有的组合式塔基通常为一方形或十字形中心件与在四个方向上伸出端件构成 十字臂， 部分组合式塔基还在中心件与端件之间加上若干过渡件以扩展十字臂长度， 这些 组合式塔基不但部件数量多， 加工及安装麻烦， 并且十字臂上存在多个拼接缝， 降低了十 字臂的刚性， 安全上存在隐患。
发明内容
本发明的目的是针对现有的塔吊基础建设周期长， 浪费建筑材料， 现有的组合式塔基 构件多， 刚度差等问题， 设计一种可在平整场地上直接安装使用、 且可反复利用、 运输方 便的组合式塔基。
本发明的技术方案是：
一种组合式塔基， 其特征是它由四个可拆拼的基础块 1组成， 每个基础块 1 由底板 2 和凸起在底板 2的承重块 3组成， 其中一个方向上的两个相对的基础块 1上的承重块 3沿 拼接端向另一端后缩， 且两个所述承重块 3 后缩的长度之和与另一个拼接方向的基础块 1 上的承重块 3的宽度 L1相配，相应地另一个方向的两个基础块 1上的承重块 3向拼接端方 向悬臂伸出， 且所述的两个承重块 3的悬臂伸出的长度之和与对应的基础块 1底板 2的宽 度 L2相配；在所述的基础块 1上均设有用于穿装连接件从而将相拼接的一个方向上的两个 基础块 1相连的纵向通孔 4，且两个方向上的基础块 1上的纵向通孔 4离底板 2底面的高度 不同， 同时还至少在两个底板端部相接触拼接的两个基础块 1 上设有供另两个端部非接触 拼接的基础块上的连接件通过的横向通孔 5。
所述的承重块 3 由上下两部分组成， 下部与底板 3整体相连， 上部通过连接螺栓与下 部相连。
所述的承重块 3的上下接合面之间设有相互配合的防滑用凹凸结构。
所述的相互拼接的一个方向上的两个基础块 1 的底板 2的端面呈错位拼接的台阶结构
6。
所述的纵向通孔 4和横向通孔 5均位于底板 2上。
所述的相邻的基础块 1之间设有可拆卸的连接筋 7。
所述的连接筋 7与基础块通过螺栓结构相连或通过卡扣结构相连。
所述的基础块 1 的底板 2的非拼接端呈翼状结构； 所述的基础块两两拼接后形成的两 个方向在同一水平面上相互垂直。
所述的连接件为钢索或钢棒。
所述的一个方向上的两个基础块为整体相连的结构并可省略纵向通孔， 另一方向上的 两个基础块为分体式或整体相连的结构， 当另一个方向上的两个基础块为整体相连的结构 时， 其上的纵向通孔也可省略。
本发明的有益效果：
本发明结构简单， 装拆、 运输方便， 尤其是采用钢索将同一个方向上的两个基础块相 连， 十分便于现场施工。 通过将一个塔基分成四段进行运输， 可减少运输尺寸， 同时保证 塔基有足够的支承面。
本发明连接可靠， 稳定性好。
本实用新件的构件数量少， 加工安装方便， 接缝少， 组成形成的正交十字形塔基的整 体刚性好， 安全可靠。 附图说明
图 1是本发明的立体分解结构示意图。
图 2是本发明的俯视结构示意图。
图 3是图 2的 A-A剖视图。
图 4是图 2的 B-B剖视图。 具体实施方式
下面结合附图和实施例对本发明作进一步的说明。
如图 1-4所示。
一种组合式塔基， 它由四个可拆拼的基础块 1组成， 如图 1所示， 基础块 1 由钢筋混 凝土浇铸而成， 其中用于与塔架底座相连的连接螺栓或螺母均在浇铸时提前预埋。 每二个 基础块组成一个方向， 两个方向上的基础块连接成一个整体后应在同一水平面内呈正交垂 直状态。 每个基础块 1 由底板 2和凸起在底板 2的承重块 3组成， 承重块 3可采用整体式 结构， 也可采用分体式结构， 采用分体式结构时必须通过预埋螺母、 螺管或螺栓， 再通过 螺纹相连组成一个具有一定高度的承重块 3， 采用分体式承重块时，承重块 3的上下接合面 之间设有相互配合的防滑用凹凸结构， 如图 3、 4。 其中一个方向上的两个相对的基础块 1 上的承重块 3沿拼接端向另一端后缩， 且两个所述承重块 3后缩的长度之和与另一个拼接 方向的基础块 1上的承重块 3的宽度 L1相配（即后缩的长度之和应不小于承重块的宽度）， 相应地另一个方向的两个基础块 1上的承重块 3 向拼接端方向悬臂伸出， 且所述的两个承 重块 3的悬臂伸出的长度之和与对应的基础块 1底板的宽度 L2相配（即伸出端的长度之和 应不小于对应底板的宽度）， 如图 2所示； 在所述的基础块 1上均设有用于穿装连接件 （可 为钢索或钢棒） 从而将相拼接的一个方向上的两个基础块 1相连的纵向通孔 4， 如图 3、 4 所示， 且两个方向上的基础块 1上的纵向通孔 4离底板 2底面的高度不同， 以防止穿装连 接件时产生干涉， 同时还至少在两个端部相接触拼接的两个基础块 1 上设有供另两个端部 非接触拼接的基础块上的连接件通过的横向通孔 5， 如图 4所示。
具体实施时相互接触拼接的一个方向上的两个基础块 1 的底板 2的端面呈错位拼接的 台阶结构 6， 以提高抗倾覆能力， 如图 4所示。
具体实施时， 所述的纵向通孔 4和横向通孔 5既可位于全部位于底板 2上， 也可全部 位于承重块 3上， 也可部分位于底板 2， 部分位于承重块 3上。
为了进一步提高塔基的稳定性， 具体实施时还可在相邻的基础击块 1 之间搭设可拆卸 的连接筋 7，连接筋 7与基础块通过螺栓结构相连或通过卡扣结构相连， 同时还可将基础块 1的底板 2的非拼接端设计成翼状结构。
此外， 具体实施时， 任一个方向的两个基础块 1 还可做成一个整体结构， 此时可省去 纵向通孔 4， 至少横向通孔 5是否可以省去， 应由该方向与另一方向卡接时卡接部位是在上 部还是下部决定， 当在下部时应保留横向通孔 5， 而另一个方向的两个基础块 1既可做成分 体式结构， 也同样可以做成一个整体式结构， 做成整体式结构时， 其上的纵向通孔 4也可 省去， 横向通孔 5可根据实际情况决定去留。 从运输方便出发考虑， 一个方向采用整体式 结构时其塔基的尺寸受到运输车辆长度的影响， 可能不如分体式结构的基础块的塔基的尺 寸大， 因此， 是否采用整体式结构应根据塔吊的吨位加以确定。
本发明未涉及部分均与现有技术相同或可采用现有技术加以实现。
