Description

用于连接两个物体的连接件及用该连接件连接的预制构件 技术领域
本发明属于建筑构件技术领域，涉及一种用于连接两个物体的连接件及用该连接件连接的预制构件。
背景技术
因沉管灌注桩的质量稳定性相对较差，近年来，预制预应力混凝土桩得到迅猛的发展，预应力混凝土方桩就是其中一种桩型，现有的混凝土预应力方桩一般具有正方形的横截面。在打桩过程中，要根据不同的需要选择不同长度的桩，这就需要桩与桩之间通过相互连接来形成较长长度的桩体。
另外，在桥梁、水管连接、涵洞建筑等领域，也需要将预制件进行连接，通常有插接、水泥浆糊接、钢筋连接等方法，但上述的这些方法连接不方便，影响施工进度。
现有的预制件的两端设有钢板，方桩通过钢板之间的相互焊接来进行连接。连接后的桩体在压桩时压入地下后，由于在土壤中含有盐分尤其是氯盐，对暴露在土壤中的钢板会形成腐蚀，导致桩与桩之间的连接处断裂，从而使连接桩断开。另外，通过钢板的焊接进行连接的方式相对复杂，连接不便。因此，人们提供了一种用插接件进行连接的方法，插接件的使用大大提高了预制件之间的连接速度和强度，同时也能防止被腐蚀。
如本申请人在之前申请的专利中公开了一种预应力混凝土八角方桩[申请号：201410541960.9]，提供了一种可以使两个桩体端部相互连接的插头组件和插槽组件，插头组件包括固定在方桩本体内的插头底座及延伸出方桩本体外部的插头，所述的插槽组件包括固定在方桩本体内的插槽及与插槽的口部固定连接的密封环，当插头插入到插槽中时，插头与密封环密封连接。插头和插头底座为可拆卸结构，插头与插头底座相邻的一端设有具有内螺纹的螺纹孔，插头底座上设有具有外螺纹的螺柱，所述的螺柱与螺纹孔相互配合，当螺柱与螺纹孔螺接时，所述的插头与插头底座螺接。插头包括插接头和插接部，插接头和螺纹孔位于插接部的两端，所述的插接部呈上口大下口小的倒圆锥台形，所述的密封环的内腔呈上口大下口小的倒圆锥台形，所述的插接头呈两头小中间大的鼓形。插槽内且位于密封环下方设有一个卡环，当插接部插入到插槽中时，所述的卡环卡设在插接部上。插槽内还设有一个弹性件，所述的弹性件一端抵靠在插槽底部，另一端与抵靠在卡环上。卡环的形状与插接头和插接部的连接处的形状相配适，所述的密封环与插槽螺接。
上述方案的插头组件和插槽组件能够使两个桩体快速连接，且连接牢固。但是该方案也有美中不足之处是：插头底座只有一个用于支撑钢筋膨大部的支撑面，由于膨大部的表面为非规则的形状，因此卡台在与膨大部接触时接触面积较小，如张拉力过大，膨大部容易脱离卡台，造成连接失败。

具体实施方式
下面结合附图和具体实施方式对本发明做进一步详细的说明。
实施例1
本发明提供了一种用于连接两个物体的连接件，如图9所示，包括两个连接螺母10，其中一个连接螺母10内螺接有插接件20，插接件20的一端为插接主体端21，具有外螺纹，用来与连接螺母10螺接固定，另一端具有插接头22，该插接头22与插接主体端21之间具有环形的卡槽23，另一个连接螺母10内螺接有中间螺母30，中间螺母30中间具有呈圆台锥形的中间通道301，该连接螺母10的卡台13上依次设置有弹性组件31和定位卡环 32，当插接件20穿过中间螺母30并插入到定位卡环32中时，所述的定位卡环32能卡住插接件20从而使两个连接螺母10相互连接。
图如2所示，连接螺母10包括相互连接的连接端11和张拉端12，在连接端11内壁设有内螺纹，张拉端12和连接端11内部具有相互连通的通孔，且张拉端12的内壁孔径小于连接端11的内壁孔径，从而使张拉端12内壁和连接端11内壁的连接处形成能卡住连接棒19上的膨大部191的卡台13，所述的卡台13的外表面由至少两个不在同一平面上的支撑面14相互连接而成。膨大部191与卡台13上的多个支撑面14形成多级支撑，加大接触面积(接触面积可达80％以上)，从而提高了连接螺母10的卡台13的抗张拉力，防止连接棒19被拉脱。连接棒19通常用钢材制成，如钢棒或钢筋等。
图16所示为现有技术的连接螺母10，其卡台13只有一个支撑面14，由于膨大部191的表面为非规则的形状，因此卡台13在与膨大部191接触时接触面积较小，如张拉力过大，膨大部191容易脱离卡台13。另外连接端11和张拉端12的外壁均为弧形。
其中，支撑面14可以是平面形，也可以是弧线。图2所示的连接螺母10有两个支撑面14，均为平面形；图3所示的连接螺母10也是两个支撑面14，其中一个支撑面14为平面结构，另一个支撑面14为弧形结构，弧形结构的支撑面14连接张拉端12的内壁；图4所示的连接螺母10的两个支撑面14均为弧形结构；图6所示的连接螺母10有3个支撑面14，均为平面形。
如图1所示，如果要使两个连接螺母10之间实现张紧连接，可将两个连接螺母10套入到连接棒19中，连接棒19的两端墩粗后形成膨大部191，膨大部191卡在卡台13上，再将两个连接螺母10向相反方向张拉，即可使两个连接螺母10实现张紧连接。
图50所示为连接螺母10张拉过程的原理图。连接棒19两端的连接螺母10分别连接在固定板91和张拉板92上，固定板91处的连接螺母10用固定螺栓93拧紧从而使连接螺母10与固定板91固定连接，张拉板92处的连接螺母10用张紧螺栓94螺接，张紧螺栓94固定在张拉板92上，定位套95的两端连接张拉板92和张拉连接板96，张拉螺母98固定在张拉连接板96上，丝杆97与张拉螺母98固接，转动丝杆97，张拉螺母98带动张拉连接板96移动，从而带动张拉板92移动，连接棒19两端的连接螺母10分别卡住膨大部191，从而被张紧。在张紧过程中，卡台13与膨大部191的接触面呈挤压状态，因此，接触面面积越大，则能承受的张拉力越大。在张拉过程中，如要保持轴向呈直线，张拉板92、定位套95和张拉连接板96均套入到管模99中。
张拉端12的外壁呈边数不小于4的多边形，如图7所示，张拉端12外壁呈正六边形，如图8所示，张拉端12外壁呈正方形。优选的，该多边形的边数为2的整数倍，也可以是8边形，10边形等等。在张拉端12的外壁和连接端11的外壁之间具有止挡台阶15，当卡具卡住张拉端12时，所述的止挡台阶15能阻止卡具滑向连接端11，从而使卡具固定张拉端，在连接端11中可以螺入连接螺丝，便于张拉。
下表为本申请与现有技术的强度对比。
Figure PCTCN2016000300-appb-000001
从上表可以看出，较之现有技术，本申请的强度要求更高，也就是本申请能够达到更高的张拉力，连接更可靠。通过分析比对，本申请比现有技术的强度普遍要提高10-20％。
连接螺母10还具有另一种方案，可以将已经墩粗的连接棒19插入到连接螺母中，如图5所示，具体的结构是在连接螺母10侧壁上开设能让连接棒上的膨大部191进入的膨大部通道16，连接螺母10侧壁上设有能让连接棒19进入的钢棒通道17且所述的钢棒通道17延伸到张拉端12的底部，膨大部通道16连接钢棒通道17，膨大部191和连接棒19先分别进入到膨大部通道16和钢棒通道17中并进一步进入到连接螺母10内部，连接螺母10的卡台13往膨大部191方向移动后即可卡住膨大部191。这种设计的优点是可以将连接棒19两端预先墩粗形成膨大部191，再与连接螺母10连接，从而用于不同的连接工艺。
如图12所示，中间螺母30具有外螺纹，中间螺母30靠近弹性组件31的一端内壁具有卡环定位腔33及与卡环定位腔33相连接的卡环止位腔34，所述的定位卡环32通过弹性组件31的弹力作用贴紧在卡环定位腔33的内壁上，当定位卡环32沿着卡环定位腔33的内壁向卡环止位腔34方向移动并触碰到卡环止位腔34时，所述的卡环止位腔34时能阻止定位卡环32移动从而防止定位卡环32滑出卡环定位腔33。中间螺母30的端部内壁还设有一个与卡环止位腔34相连的弹性件定位腔35，弹性件定位腔35与卡环止位腔34光滑过渡。
如图13所示提供了中间螺母30的另一种结构，卡环止位腔34的内壁与中间螺母30的轴心线平行，弹性件定位腔35呈圆环形。
卡环定位腔33的内壁和卡环止位腔34的内壁的倾斜度不同，及两个内壁之间具有夹角a，该夹角a处起到止挡作用。优选方案，卡环定位腔33的内壁和卡环止位腔34的内壁之间具有夹角a且夹角a为130-160°之间的钝角。如图15所示，所述的定位卡环32包括若干块形状、大小相同的定位卡片321，若干定位卡片321沿中间螺母30的轴心线周向均匀分布并合围形成定位卡环32。图15中，定位卡环32由4片定位卡片321组成，在实际应用中，凡是不小于2片的定位卡片321均可组成定位卡环32。定位卡片321的外壁与卡环定位腔33的内壁相配适，定位卡片321内壁与插接头22的外表面相配适，定位卡片321内壁还可以设置锯齿，用来提高与插接头22的摩擦力。
图14提供了现有技术的中间螺母30的示意图，具有卡环定位腔33，没有卡环止位腔34。由于卡环止位腔34对定位卡环32没有止挡作用，因此当插接件20插入速度过快时，定位卡环32会一直沿着卡环定位腔33滑动，脱离中间螺母30的端部，造成连接失败。
图19是现有技术的连接件的结构示意图，中间螺母30具有外螺纹，内壁具有能让插接件20插入的中间通道301，插接件20的端部具有插接头22，在插接头22插入到中间螺母30的过程中，定位卡环32内壁紧贴插接头22外壁，中间螺母30的端部膨大呈一个具有斜面的卡环定位腔33，卡环定位腔33用于放置定位卡环32，当插接头22完全插入到定位卡环32中后，插接头22的卡槽23卡住定位卡环32，定位卡环32对插接头22形成卡接固定。在插接头22插入的过程中，如速度过快，定位卡环32会顺着卡环定位腔33的斜面一直滑动，直至滑出中间螺母30，导致定位卡环32无法卡入到卡槽23中，这就是现有技术的缺陷。由于连接用于预制件中，如定位卡环32掉落，则无法起到连接作用，给施工带来极大的麻烦。
在本实施例中，插接件20与定位卡环32连接时的受力分析如图17和图18所示。当插接头22沿图17中的箭头方向插入到定位卡环32中时，定位卡片321的P1、P2和P3三点受力，其中P3的受力点在卡环定位腔33和卡环止位腔34的夹角处，由于卡环止位腔34形成阻挡而受力，众所周知，三点支撑是最稳固的支撑方式，从而使定位卡环32不会滑出卡环定位腔33和；如图18所示，当插接头22沿图中的箭头方向拉紧卡环100时，定位卡片321的P1、P2和P3三点也同样受力，同样也形成三角支撑，从而使定位卡环321卡紧在卡槽23处；综上所述，在插接头22插入定位卡环32的过程中，由卡环定位腔33和卡环止位腔34形成的夹角能提供一个支撑支点，从而使定位卡片321和/或定位卡环32在中间螺母30和插接头222的联合作用下得到稳定的三角支撑，定位卡片321和/或定位卡环32不会掉出中间螺母30，而当插接头22完成插入后，定位卡环32也得到三角支撑，对插接头22形成稳固的卡接固定。
结合图10和图11能够更清楚的了解插接件20到插入定位卡环32过程中及插入后的状态。如图10所示，插接件20在插入定位卡环32的过程中，尚未完成连接。此时定位卡环32位于弹性组件31、中间螺母30和插接头22之间，形成定位支撑，定位卡环32始终位于卡环定位腔33内；如图11所示，当插接头22完全插入到定位卡环32中时，两个连接螺母10实现对接，定位卡环32卡在卡槽23中，此时定位卡环32位于弹性组件31、中间螺母30和卡槽23之间，形成定位支撑。
弹性件定位腔35与弹性组件31相配适且当中间螺母30螺入到连接螺母10中时，弹性组件31的端部恰好卡入到弹性件定位腔35中。在本实施例中，弹性组件31包括弹簧311和压设在弹簧311上的弹簧压片312，所述的定位卡环32压设在弹簧压片312上。弹簧压片312与弹性件定位腔35的形状相配适，从而在连接时弹簧压片312和中间螺母30对定位卡环32起到压制定位作用，防止定位卡环32上下移动。
优选方案，如图53和图54所示，插接件20一端为插接主体端21，另一端具有插接头22，在插接主体端21和插接头22的连接处形成向内凹陷的卡槽23，所述的卡槽23外壁设有至少一个与定位卡环32内壁相配适的张拉卡圈24，当插接件20插入到定位卡环32中时，张拉卡圈24与定位卡环32内壁形成卡接配合。
张拉卡圈24可以与定位卡环32/定位卡片321形成卡接固定的抗拉结构，从而减少预制件1用连接件连接时产生的空隙，也就是说插接件20与定位卡环32之间的抗拔力能提高，从而减少插接件20活动距离，减少两个预制件1之间的空隙，使连接更牢固，更稳定。
图55是插接件为插入到中间螺母中时的结构示意图，这时插接件20与定位卡环32/定位卡片321未形成卡接配合，图56是插接件部分插入到中间螺母中时的结构示意图，此时插接件20与定位卡环32/定位卡片321，图56中的L1是指试验时填设的垫片的厚度，目的了为了精确控制插接件20插入到定位卡环32/定位卡片321中距离，图插接件完全插入到中间螺母中时的结构示意图，L2是指试验时填设的垫片的厚度。经过对具有张拉卡圈24和没有张拉卡圈24的插接件20的试验数据的比对，可以得出结论，具有张拉卡圈24的插接件20的抗拔性能更优异。下表为数据比对。其中本申请是指具有张拉卡圈24的插接件20，现有技术是指没有张拉卡圈24的插接件20，垫片厚度是指图56中的L1或图57中的L2的数值，拉力是对指对插接主体端21施加的拉力值，在进行拉力试验时，中间螺母30处于固定状态。
Figure PCTCN2016000300-appb-000002
从上述的表格中看出，在同等拉力条件下，具有张拉卡圈24的插接件20比没有张拉卡圈24的插接件20的拉伸间距普遍要少1mm以上，也就是说张拉卡圈24提高了抗拔性能。
实施例2
如图35所示，本发明还提供了一种用上述的连接件连接的预制构件，该预制构件包括若干个各自独立且相互连接的预制件1，且至少有两个预制件1之间通过连接件连接。本实施例所述的预制件1为预制桩，如方桩、圆柱、空心桩、实心桩、变截面桩、不变截面桩等。
用连接件连接的具体方式是：如图34和图9所示，在两个预制件1的端部分别设置至少一个一一对应的连接螺母10，其中一个预制件1中的连接螺母10中螺接有插接件 20，另一个预制件1中的连接螺母10中螺接有中间螺母30，中间螺母30中间具有呈圆台锥形的中间通道301，该连接螺母10的卡台13上依次设置有弹性组件31和定位卡环32，当插接件20穿过中间螺母30并插入到定位卡环32中时，所述的定位卡环32能卡住插接件20从而使两个连接螺母10相互连接，并使两个预制件1实现连接。
优选方案，至少有两个预制件1的横截面的截面积大小不相等，也就是使桩体形成变截面桩，从而提高抗拔力。更优选地，预制件1按大截面预制件和小截面预制件相互交替连接形成桩体，从而使桩体形成凹凸配合的结构，提高抗拔力。
预制件1的两端分别固定有若干连接螺母10，且位于预制件1两端的连接螺母10一一对应并用连接棒19连接固定，连接棒19两端的膨大部191分别卡住以连接螺母10，该两个连接螺母10分别位于预制件1的两端，每两个预制件1的连接处至少用一个上述的连接件连接固定，优选地，连接螺母10在预制件1的端部均匀排列，呈环形或阵列排列。
实施例3
本实施例与实施例2的结构和工作原理基本相同，不同之处在于，如图36所示，预制件1的一端具有若干连接螺母10，另一端具有连接端板40，两个相邻的预制件1之间用连接件或连接端板40连接固定。
如图41所示，连接端板40上具有与连接螺母10一一对应的张拉孔机构41且所述的张拉孔机构41和连接螺母10之间用连接棒19连接固定。在现有技术中，连接端板40之间通过焊接或用螺栓固定连接，从而实现两个预制件1之间的连接。如图51和图52所示，两块连接端板40在连接的接口处具有环形的凹陷部40a，用电焊焊接凹陷部40a的底部，形成环形的电焊圈40b，从而使两块连接端板40固定连接。
本实施例提供了另一种连接方法，结合图44所示，连接端板40的外壁并沿连接端板40的周向设有锁紧孔机构42，当两个预制件1之间通过连接端板连接时，锁紧孔机构42内设置有两端分别插入到两个锁紧孔机构42中且能使两块连接端板40相互锁紧的锁紧块组件43。
如图46-48所示，张拉孔机构41包括相互连接的膨大部孔411和张拉孔412，其中膨大部孔411的孔径要大于膨大部191从而能让膨大部进入，张拉孔412的孔径小于膨大部191从而使张拉孔412能卡住膨大部191，且膨大部孔411和张拉孔412形成“8”字型结构，在安装连接端板40时，现将膨大部孔411与膨大部191一一对应从而使连接端板40套在连接棒19上，再转动一定的角度，使连接棒19进入到张拉孔412中，此时膨大部191卡住张拉孔412。连接端板40通常应与预制件1的截面形状相配适，如图46-48所示分别为圆形、矩形和六边形。
图如42、图45和图49所示，锁紧孔机构42包括至少一个锁紧孔421，所述的锁紧块组件43包括两个锁紧块431，锁紧块431的形状与锁紧孔421相配适，两个锁紧块431之间用螺栓固定连接。
再结合图49所示，锁紧孔421远离预制件1的一侧设有具有向锁紧孔421内凹陷的锁紧凹槽422，所述的锁紧块431具有与锁紧凹槽422形状相配适的锁紧定位块432。
如图43所示，是本实施例提供的另一种连接端板40的结构示意图，连接端板40靠近预制件1的一侧还可以设置管状的连接套管44，连接套管44套设在预制件1的端部外壁上，从而加强连接。
实施例4
本实施例与实施例3的结构基本相同，不同之处在于，如图21和图22所示，预制件1内部具有至少一个空心通道2，该空心通道2的两端延伸出预制件1的两端或封闭在预制件1内部。
如图21所示，当空心通道2的两端封闭在预制件1内部时，空心通道2的两端分别固定有一块隔离板50，且隔离板50位于预制件1内部。隔离板50的面积应大于等于空心通道2的截面积，从而能将空心通道2两端堵住，为了能使隔离板50固定在预制件1中，隔离板50的周向边缘可设置若干定位条51。
如图29所示的隔离板50为矩形，具有4条定位条51；如图30所示的隔离板50为圆形；如图31所示的隔离板50为圆形，具有3条定给条51；如图32所示的隔离板50为圆形，具有5条定位条51。
实施例5
本实施例与实施例2-3的结构基本相同，不同之处在于预制件1的结构不同，如图20所示，预制件1由大截面桩101和小截面桩102依次连接而成。大截面桩101和小截面桩102之间通过变截面桩103连接，变截面桩103为沿轴向分布的横截面不同，且该不同之处应大于预制件领域的制造误差。预制件1的两端分别具有一一对应的连接螺母10，连接棒19两端分别连接一个连接螺母10，在连接棒19的周向还固定有若干缠绕钢筋192，且连接螺母10与预制件1的端部之间具有一定距离的插接口36，如图33所示，插接口36呈喇叭状，便于连接其他部件，同时也防止同一连接件上的两个连接螺母10发生撞击。
实施例6
本实施例在实施例4和实施例5的基础上增加了一个凹凸卡台机构60，如图20、图21和图28所示，预制件1的两端具有凹凸卡台机构60，当两根相邻的预制件1相互靠近时，凹凸卡台机构60能够让两根预制件1卡接配合。
凹凸卡台机构60包括设置在预制件1一端的凹台61及设置在预制件1另一端的凸台62，所述的凸台62和凹台61的形状、大小相配适，当凸台62插入到凹台61中时，凸台62和凹台61形成卡接配合。预制件1的两端分别设有一个抱箍104，抱箍104呈环形结构。
凸台62和凹台61可以是不同的形状，同样大截面桩101和小截面桩102的横截面也可以是不同的形状。
如图23-27示出了5种不同的凸台62和截面的形状。如图23所示的凸台62为圆台锥形，大截面桩101和/或小截面桩102的截面为六边形，连接螺母10按六边形均匀排列；
图24所示的凸台62为圆台锥形，大截面桩101和/或小截面桩102的截面为圆形，连接螺母10按圆形均匀排列在凸台62周围；
图25所示的凸台62为立方台形，大截面桩101和/或小截面桩102的截面为矩形，连接螺母10按矩形均匀排列在凸台62周围；
图26所示的凸台62为圆柱形，大截面桩101和/或小截面桩102的截面为矩形，连接螺母10按矩形均匀排列在凸台62周围；
图27所示的凸台62为六方柱形，大截面桩101和/或小截面桩102的截面为六 边形，连接螺母10按六边形均匀排列在凸台62周围。
如图58所示，凹凸卡台机构60也可以是另外一种结构，包括设置在预制件1一端的至少两个凹台61及设置在预制件1另一端的至少两个凸台62，所述的凸台62和凹台61的形状、大小、数量相配适，所述的凹凸61和凸台62为环形结构，当凸台62插入到凹台61中时，凸台62和凹台61形成卡接配合。这种结构具有较好的密封效果，防止外部的液体进入到预制件1的中心处。
实施例7
本实施例为实施例1所述的连接件用于连接自来水管，具体的连接方法与实施例2的连接方法相同，不同之处在于，在本实施例中，自来水管81即为预制件1。如图37所示，两根自来水管81通过套接配合，在两根自来水管81的套接处分别设置一一对应的连接螺母10，再通过如实施例1所述的连接件进行连接。
实施例8
本实施例为实施例1所述的连接件用于桥墩连接，具体的连接方法与实施例2的连接方法相同，不同之处在于，在本实施例中，桥墩承台82、桥墩立柱83、连接横梁84即为预制件1。如图38所示，桥墩承台82连接桥墩立柱83，桥墩立柱83连接横梁84，桥墩立柱83也可以是多段连接，连接处也分别设置一一对应的连接螺母10，再通过如实施例1所述的连接件进行连接。
