Description

模板拼装用连接卡具 技术领域
本发明属于建筑模板连接器件领域，涉及一种模板拼装用连接卡具。
背景技术
现有技术中，建筑模板，钢质模板或木质模板在拼装连接使用时，大多采用普通的螺栓、螺母穿孔式拼装连接的方式，这种传统的连接器件有着明显的不足：施工速度慢，模板拼装质量不易保证，在施工现场易被损伤，而且受震后易于自行松动，有时会严重影响砼浇注质量：也有不少企业采用如：中国专利ZL99205850·3中公开的拼装套卡，其结构为：主体件上具有双钩脚，并有与双钩脚相对而置的带鞍型板的顶紧螺栓，使用时，模板边框上需具有配套的双孔，双钩脚钩入双孔中，鞍型板骑在两模板边框的顶部，然后锁紧顶紧螺栓即可，此种连接器件的最大优点是掩工速度快，但仍有明显的不足之处：模板边框必须有规范的双孔，在施工现场也容易被损伤，受震动后易于自行松动，同时对双钩脚内尺寸要求严格，而多次使用后，无论是模板边框的配套双孔还是双钩脚本身都会因磨损而发生尺寸偏差，因而会给模板拼装质量带来难以避免的影响，从而影响砼浇注质量；再如：中国专利ZL01271107.1所公开的夹具方案，由三部分组成：带楔齿的楔俸、带齿条的左半卡件和右半卡件，使用时，左、右两半卡件对位卡在模板的边框上，此时，左半卡件上的齿条穿过右半卡件的槽道，然后将楔体从槽道的纵向孔中插入并与横向齿条啮合在一起，施加楔紧力时，由于斜齿功能，楔齿与齿条啮合状态下产生横向位移， 从而带动两半卡件互相紧紧结合在一起；此种夹具的最大优点是旌工速度快、模板拼装紧固可靠，模板的边框上也无需打孔，但存在成本高以及其他不尽人意之处：再如中国专利ZL03137432·8所公开的新式连接器，主要由异型板栓和配套的丁字弹簧楔板组成，使用时，异型板栓穿过拼装模板边框上的连接孔，丁字弹簧楔板的条形孔套在栓肩上并卡在栓头的里边面上，楔紧后，楔身产生一定的弹性弯曲，其最大优点是结构简单、施工方便，耐磨损和耐碰撞，使用寿命长，其不足之处在于，楔身的弹性弯曲易出现疲劳，并且人工楔紧力度不易把握，使用时，逐个穿孔紧固仍影响施工速度，同时也易发生丢失等。
发明内容
本发明针对上述存在的问题和不足，提供一种模板拼装用连接卡具，采用活动夹扣与锁紧件紧固相结合，而且夹扣与锁紧件合为一体的结构作为模板拼装连接器，能克服现有技术中存在的不足，模板边框上无需打拼装孔，结构简单，使用方便、锁紧及拆卸速度快，不易损伤和丢失，成本低，使用寿命长，夹扣紧固过程中，模板能自动定位、找平，模板拼装使用中受力状态好，紧固可靠、拼装质量高。
为了达到上述目地，本发明的技术方案是这样实现的：
本发明所述的模板拼装用连接卡具，其特点是包括左夹扣和右夹扣，所述左夹扣和右夹扣通过转轴可转动的连接在一起，所述左夹扣和右夹扣的前端夹头部位具有与模板的边框配套对应的卡紧面和定位兼校平面，所述左夹扣和右夹扣后部设有可使左夹扣和右夹扣的前端夹头部位形成夹紧两相邻模板的边框的锁紧装置。
为了使本发明的结构多种多样，既可以是上述锁紧装置包括设置于左夹 扣后部的穿孔、可上下移动地穿置于该穿孔内的斜楔块，其中所述斜楔块的一侧面对应右夹扣的后部，随斜楔块的向下移动可推动左夹扣和右夹扣绕转轴转动，使左夹扣和右夹扣的前端夹头部形成夹紧两相邻模板边框的动作，此时，所述左夹扣的穿孔开口一体向上延伸形成有可定位斜楔块向下移动的挡板，所述斜楔块的底部设有销孔，该销孔内装有可防止斜楔块脱离上述穿孔的止挡销柱体，也可以是上述锁紧装置包括设置于左夹扣后部的穿孔、可转动地装置于该穿孔内的凸轮体，随凸轮体在该穿孔内的转动可推动右夹扣的后部绕转轴转动而使其前端夹头部形成夹紧两相邻模板边框的动作，此时，所述左夹扣上位于其穿孔的一侧装置有一用于定位凸轮体转动范围的定位件。
为了使本发明的使用方便，上述左夹扣和右夹扣之间设有一用于使其前端夹头部在设有锁紧装置作用时处于开口状态的复位装置。为了使复位装置的结构多种多样，既可以是所述复位装置为套装于上述转轴上的复位弹簧，其中该复位弹簧的一端固定于左夹扣后部，其另一端固定于右夹扣后部，也可以是所述复位装置为装置于左夹扣和右夹扣后部之间的拉簧，该拉簧的一端固定于左夹扣后部，其另一端固定于右夹扣后部。
本发明由于采用了相邻铝模板之间的连接是通过一高强度的旋转扣实现的结构，此种连接结构的主要优点：
1、连接稳固。铝模板侧筋的凹槽和凸台结构，与旋转扣的夹头相互配合，当旋转扣的斜楔受力沿着插孔下移，其斜面与旋转扣的右夹扣接触，并驱动右夹扣围绕转轴进行逆时针旋转，迫使旋转扣的夹头与铝模板的凹槽紧密结合在一起，斜楔向下位移越大，模板与模板之间的连接越稳固。至于铁 销钉连接，由于销孔易磨损，使用多次后模板连接的紧密度会越来越低，模板之间的间隙会越来越大，相比之下，旋转扣连接比铁销钉连接更紧密、稳固、安全；
2、易拆装，搭建快速。只需一把铁锤就可以轻易进行模板的拆装工作。连接模板时只需把旋转扣的斜楔抽起并脱离右夹扣的插孔，并用力握住旋转扣尾部使得左右夹扣的夹头分开，同时把夹头放置在模板的凹槽处，然后用铁锤敲紧斜楔，即可使两模板紧密连接一起；拆卸过程与安装过程刚好相反。用铁销钉连接的铝模板，其安装时把铁销钉插入模板侧筋的销孔，然后把斜楔插入铁销钉的插槽并敲紧，同时亦要把斜楔敲弯，以保证铁销钉不会松脱；拆卸时要先把斜楔敲直才能松开铁销钉。对比之下，用旋转扣连接更简易，更快捷；
3、使用寿命长。铁销钉连接的方式需要在模板侧筋钻销孔，铁销钉与模板接触面积小，模板受力时销孔边缘易损坏；而用旋转扣连模板则不需对模板进行如钻孔等材料结构破坏，模板侧筋受力面积，不易损坏。对比后，旋转扣连接的模板比铁销钉连接的模板的使用寿命更长；
4、经济实惠。旋转扣采用高强度铸钢铸造成型，不易损坏，可以循环使用；其次使用旋转扣连接，模板的使用寿命长，使用的次数多，大大降低工程的施工成本。铁销钉连接的模板由于销孔易磨损，使用的次数比用旋转扣连接的模板少，其次用于紧固铁销钉的斜楔使用多次后就需更换，循环使用的次数少。综合对比，使用旋转扣连接比铁销钉连接更经济实惠。另外，铝模板相比其它的木模板或铁木模板的回收利用率高，工程的施工成本更低。
下面结合附图对本发明作进一步的说明。

具体实施方式
如图1-图11所示，本发明所述的模板拼装用连接卡具，包括左夹扣1和右夹扣2，所述左夹扣1和右夹扣2通过转轴3可转动的连接在一起，所述左夹扣1和右夹扣2的前端夹头部位具有与模板10的边框101配套对应的卡紧面13和定位兼校平面14，所述左夹扣1和右夹扣2后部设有可使左夹扣1和右夹扣2的前端夹头部位形成夹紧两相邻模板10的边框101的锁紧装置。为了使本发明的结构多种多样，既可以是所述锁紧装置包括设置于左夹扣1后部的穿孔11、可上下移动地穿置于该穿孔11内的斜楔块4，其中所述斜楔块4的一侧面对应右夹扣2的后部，随斜楔块4的向下移动可推 动左夹扣1和右夹扣2绕转轴3转动，使左夹扣1和右夹扣2的前端夹头部形成夹紧两相邻模板边框的动作，此时，所述左夹扣1的穿孔11开口一体向上延伸形成有可定位斜楔块4向下移动的挡板12，所述斜楔块4的底部设有销孔41，该销孔41内装有可防止斜楔块4脱离上述穿孔11的止挡销柱体5，也可以是所述锁紧装置包括设置于左夹扣1后部的穿孔11、可转动地装置于该穿孔内的凸轮体6，随凸轮体6在该穿孔11内的转动可推动右夹扣2的后部绕转轴3转动而使其前端夹头部形成夹紧两相邻模板边框的动作，此时，所述左夹扣1上位于其穿孔11的一侧装置有一用于定位凸轮体6转动范围的定位件7。为了使本发明的使用方便，所述左夹扣1和右夹扣2之间设有一用于使其前端夹头部在设有锁紧装置作用时处于开口状态的复位装置。为了使复位装置的结构多种多样，既可以是所述复位装置为套装于上述转轴3上的复位弹簧8，其中该复位弹簧8的一端固定于左夹扣1后部，其另一端固定于右夹扣2后部，也可以是所述复位装置为装置于左夹扣1和右夹扣2后部之间的拉簧9，该拉簧9的一端固定于左夹扣1后部，其另一端固定于右夹扣2后部。
本发明由于采用了相邻铝模板之间的连接是通过一高强度的旋转扣实现的结构，此种连接结构的主要优点：
1、连接稳固。铝模板侧筋的凹槽和凸台结构，与旋转扣的夹头相互配合，当旋转扣的斜楔受力沿着插孔下移，其斜面与旋转扣的右夹扣接触，并驱动右夹扣围绕转轴进行逆时针旋转，迫使旋转扣的夹头与铝模板的凹槽紧密结合在一起，斜楔向下位移越大，模板与模板之间的连接越稳固。至于铁销钉连接，由于销孔易磨损，使用多次后模板连接的紧密度会越来越低，模 板之间的间隙会越来越大，相比之下，旋转扣连接比铁销钉连接更紧密、稳固、安全；
2、易拆装，搭建快速。只需一把铁锤就可以轻易进行模板的拆装工作。连接模板时只需把旋转扣的斜楔抽起并脱离右夹扣的插孔，并用力握住旋转扣尾部使得左右夹扣的夹头分开，同时把夹头放置在模板的凹槽处，然后用铁锤敲紧斜楔，即可使两模板紧密连接一起；拆卸过程与安装过程刚好相反。用铁销钉连接的铝模板，其安装时把铁销钉插入模板侧筋的销孔，然后把斜楔插入铁销钉的插槽并敲紧，同时亦要把斜楔敲弯，以保证铁销钉不会松脱；拆卸时要先把斜楔敲直才能松开铁销钉。对比之下，用旋转扣连接更简易，更快捷；
3、使用寿命长。铁销钉连接的方式需要在模板侧筋钻销孔，铁销钉与模板接触面积小，模板受力时销孔边缘易损坏；而用旋转扣连模板则不需对模板进行如钻孔等材料结构破坏，模板侧筋受力面积，不易损坏。对比后，旋转扣连接的模板比铁销钉连接的模板的使用寿命更长；
4、经济实惠。旋转扣采用高强度铸钢铸造成型，不易损坏，可以循环使用；其次使用旋转扣连接，模板的使用寿命长，使用的次数多，大大降低工程的施工成本。铁销钉连接的模板由于销孔易磨损，使用的次数比用旋转扣连接的模板少，其次用于紧固铁销钉的斜楔使用多次后就需更换，循环使用的次数少。综合对比，使用旋转扣连接比铁销钉连接更经济实惠。另外，铝模板相比其它的木模板或铁木模板的回收利用率高，工程的施工成本更低。
