Description

一种快装式混凝土模板用扣件结构装置 技术领域
本发明涉及一种混凝土模板用紧固装置，特别是涉及一种快装式混凝土模板用扣件结构装置。
背景技术
在预制混凝土构件的过程中大量使用模板，由于不同形状的建筑物使用的混凝土模板不同，因此大部分的模板不能重复使用造成了极大浪费；为此采用了标准化的模板单元，模板单元可重复使用并能拼接成各种形状的混凝土模板。但是现有的模板单元在施工时一块块地拼接，并用复杂的紧固件进行固定，效率低下且操作不便。
为了解决上述问题，本申请人申请了'一种改进混凝土模板用扣件结构'，包括扣件、锁件和弹簧，扣件的一端设有卡销且此端部内凹形成卡口，卡口与混凝土模板用固定管相适配，还包括套把，套把包括垂直连接在一起的握把和套筒，所述扣件的另一端部设有套管，套管沿所述卡口的进深方向设置，套管与套筒套接在一起并形成一个弹簧腔，所述弹簧设置在此弹簧腔内，且弹簧的两自由端分别抵顶在弹簧腔的内腔壁上；所述锁件的一端设有锁销，所述锁件的另一端穿过弹簧后与套把连接在一起。
另外还申请了一种'压扣式快装卸混凝土模板用板扣件装置'，包括压板和压扣件，压扣件的一端卡合于混凝土模板的外表面上的快接槽内，压板的一侧为贴合面，此贴合面通过下压和旋转上述压扣件弹性接抵在相邻两块卸混凝土模板的外表面上。
但是，上述扣件结构和上述扣件装置中，锁件端部上的锁销在弹簧的弹力作用下直接卡合于快接槽内，压扣件也是通过弹性件直接卡合于混凝土模板的外表面上的快接槽内，这种通过弹性件实现卡合结构，其紧固度有待于提高。
发明内容
有鉴于此，本发明的目的在于提供一种能够提高紧固度的快装式混凝土模板用扣件结构装置。
为了达成上述目的，本发明的解决方案是：
一种快装式混凝土模板用扣件结构装置，包括扣板和锁件，扣板的一端部设有卡销，扣板的另一端部设有套筒，所述锁件包括相适配的螺杆和螺母，螺杆穿设在所述套筒内且两端均穿出所述套筒外，螺杆位于所述套筒外的一端安装螺母，螺杆位于所述套筒外的另一端的端部固定有锁舌。
所述锁舌上分别设有定位台阶，或者一个所述锁舌上设有定位台阶，定位台阶卡合于混凝土模板上的快接槽内。
所述锁舌旋转卡合在混凝土模板上的快接槽内的旋转方向，与所述螺母在所述螺杆上旋转使所述锁舌抵紧在此快接槽内的旋转方向相同。
所述螺杆和 / 或所述螺母上设有用于旋转用的把手。
一种快装式混凝土模板用扣件装置，包括贴在混凝土模板的表面上的角板，以及将角板固定在混凝土模板上的锁件，所述角板具有连接在一起的第一板和第二板，第一板和第二板上分别对应开有第一槽和第二槽；所述锁件包括相适配的螺杆和螺母，第一槽和第二槽内分别分别穿设螺杆，两个螺杆的一端分别安装螺母，两个螺杆的另一端部分别固定有锁舌。
所述第一槽和所述第二槽相互平行。
所述第一槽和所述第二槽相互垂直，所述第一槽或所述第二槽平行于所述角板的角部棱线。
所述第一槽或所述第二槽为十字型槽，且所述第一槽和所述第二槽至少有一条槽边相互平行。
两个所述锁舌上分别设有定位台阶，或者一个所述锁舌上设有定位台阶，定位台阶卡合于混凝土模板上的快接槽内。
所述螺杆和 / 或所述螺母上设有用于旋转用的把手；或者所述锁舌旋转卡合在混凝土模板上的快接槽内的旋转方向，与所述螺母在所述螺杆上旋转使所述锁舌抵紧在此快接槽内的旋转方向相同。
采用上述结构后，本发明的一种快装式混凝土模板用扣件结构装置具有以下有益效果：在搭架起来的固定管上架设混凝土模板时，将扣板卡在固定管上，卡销和锁舌分别卡在混凝土模板上的快接槽内，旋转螺母使锁舌紧紧卡在快接槽内。待混凝土成型后，反向旋转螺母使锁舌从快接槽内脱开，然后将固定管、混凝土模板拆下来即可。本发明通过螺杆和螺母使锁舌紧卡在快接槽内，可提高紧固度。
采用上述结构后，本发明的一种快装式混凝土模板用扣件结构装置具有以下有益效果：拼接混凝土模板时，在两块相互垂直搭接的混凝土模板的搭接处放置角板，角板的第一板和第二板分别贴合在两块混凝土模板的外表面上，然后将两个锁舌分别卡入混凝土模板上的快接槽内，旋转螺母使锁舌紧紧卡在快接槽内；这样，在混凝土模板的内表面所围成的型腔内浇筑混凝土，待混凝土成型后，反向旋转螺母使锁舌从快接槽内脱开，然后将混凝土模板一块一块拆下来即可，本发明通过螺杆和螺母使锁舌紧卡在快接槽内，可提高紧固度。由于角板上开有第一槽和第二槽，这样可根据两块相互垂直搭接的混凝土模板的搭接处的角部安装位置，通过第一槽和第二槽相应地调整角板的位置，例如：两块相互垂直搭接的混凝土模板上的快接槽对齐在一起、相互错开或者相互垂直时，都能通过扣件装置将两块混凝土模板固定在一起，本发明具有较高的通用性，适用于多种规格的混凝土模板10a来拼接成多种形成的型腔，可提高装卸效率。

具体实施方式
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。
实施例一
如图 1 至 2 所示，本发明的一种快装式混凝土模板用扣件结构装置，包括扣板 10 和锁件 20 。
扣板 10 的一端部设有卡销 11 ，扣板 10 的另一端部设有套筒 12 。作为本发明的一个较佳实施例，扣板 10 外表面上凸设有加强筋 13 ，也可仅在扣板 10 连接卡销 11 的一端的外表面上凸设加强筋 13 。
锁件 20 包括相适配的螺杆 21 和螺母 22 ，螺杆 21 穿设在套筒 12 内且两端均穿出套筒 12 外，螺杆 21 位于套筒 12 外的一端安装螺母 22 ，螺杆 21 位于套筒 12 外的另一端的端部固定有锁舌 23 。螺杆 21 和螺母 22 上分别设有用于旋转用的把手 24 。当然，也可仅在螺杆 21 或螺母 22 上设置把手 24 ；或者螺杆 21 和螺母 22 上也可不设置把手 24 ，螺杆 21 的端部和螺母 22 的截面设成方形或者六角形，通过扳手来拧动螺母 22 。
作为本发明的另一较佳实施例，锁舌 23 的两端部分别设有定位台阶 231 ，两个定位台阶 231 的台阶面相互平行，有利于两个定位台阶 231 卡合于混凝土模板 10a 上的快接槽 11a 内（如图 5 、图 6 所示）。锁舌 23 伸入快接槽 11a 内，旋转螺杆 21 一定角度后锁舌 23 即卡在快接槽 11a 内。反向旋转螺杆 21 ，锁舌 23 即从快接槽 11a 内脱出来。通过定位台阶 231 既能防止锁舌 23 转过头卡不上，又能确保锁舌 23 与快接槽 11a 的卡合面积，避免出现因卡合面积较小或者卡合不到位而导致卡合力不够稳定的现象，从而提高扣件结构装置的安全性。
当然也可在锁舌 23 的一端部设置定位台阶 231 。另外，锁舌 23 的宽度与 T 型的快接槽 11a 的开口尺寸相当，这样恰好能够伸入快接槽 11a 内。锁舌 23 的长度大于快接槽 11a 的 T 型头在此方向上的尺寸，这样锁舌 23 上不必设置定位台阶 231 ，也可限制定位台阶 231 在快接槽 11a 内的旋转角度，避免出现卡不到位或转过头卡不上的现象，既能快速卡合，确保卡合力，进而提高安全性。
在搭架起来的固定管上架设混凝土模板 10a 时，将扣板 10 卡在固定管上，卡销 11 和锁舌 23 分别卡在混凝土模板 10a 上的快接槽 11a 内，快速旋转螺母 22 使锁舌 23 恰好卡合到位，再旋转螺母 22 使锁舌 23 紧紧卡在快接槽 11a 内。待混凝土成型后，反向旋转螺母 22 使锁舌 23 从快接槽 11a 内脱开，然后将固定管、混凝土模板 10a 拆下来即可。本发明通过螺杆 21 和螺母 22 使锁舌 23 紧卡在快接槽 11a 内，可提高紧固度。
作为本发明的再一较佳实施例，如图 2 中的箭头方向所示，卡合时先握住把手 24 顺时针旋转螺杆 21 ，使锁舌 23 卡合在快接槽 11a 内。然后握住把手 24 顺时针旋转螺母 22 ，螺杆 21 上升使锁舌 23 紧紧抵顶在快接槽 11a 的槽壁上。逆时针旋转，即可将锁舌 23 从快接槽 11a 中快速脱出。
也就是说，锁舌 23 旋转卡合在快接槽 11a 内的旋转方向，与螺母 22 在螺杆 21 上旋转使锁舌 23 抵紧在快接槽 11a 内的旋转方向相同，而且两者的旋转方向均为顺时针旋转，符合人体顺时针旋转旋紧、逆时针旋转旋松的动作习惯。当然也可反过来设置旋紧、旋松的方向。
实施例二
如图 3 至 6 所示，本发明的一种快装式混凝土模板用扣件结构装置，包括角板 10 ' 和锁件 20 ' 。
本实施例中除了角板 10 ' 与实施例一中的扣板 10 不同以外，锁件 20 ' 为两个，各锁件 20 ' 的结构分别与实施例一中的锁件 20 结构相同。
角板 10 ' 具有连接在一起的第一板 11 ' 和第二板 12 ' ，第一板 11 ' 和第二板 12 ' 上分别对应开有第一槽 111 ' 和第二槽 121 ' ；第一槽 111 ' 和第二槽 121 ' 内分别对应安装锁件 20 ' 。
锁件 20 ' 包括相适配的螺杆 21 ' 和螺母 22 ' ，两个螺杆 21 ' 分别穿设在第一槽 111 ' 或第二槽 121 ' 内。螺杆 21 ' 的一端安装螺母 22 ' ，螺杆 21 ' 的另一端部固定有锁舌 23 ' 。另外，锁舌 23 ' 上设有定位台阶 231 ' ，定位台阶 231 ' 卡合于混凝土模板 10a 上的快接槽 11a 内。螺杆 21 ' 和 / 或螺母 22 ' 上分别设有用于旋转用的把手 24 ' 。
其中，穿设在第一槽 111 ' 和第二槽 121 ' 中的两个锁件 20 ' 的结构可以相同也可不同。例如，两个锁舌上分别设有定位台阶，或者一个锁舌上设有定位台阶。两个螺杆 21 ' 和两个螺母 22 ' 上分别设有把手 24 ' ，或者一个螺杆 21 ' 和一个螺母 22 ' 上分别设有把手 24 ' 。
作为本发明的一个较佳实施例，第一槽 111 ' 和第二槽 121 ' 相互平行；或者第一槽 111 ' 、第二槽 121 ' 相互平行和角板 10 ' 的角部棱线相互平行；或者第一槽 111 ' 和第二槽 121 ' 相互垂直，第一槽 111 ' 或第二槽 121 ' 平行于角板 10 ' 的角部棱线；或者第一槽 111 ' 或第二槽 121 ' 为十字型槽，且第一槽 111 ' 和第二槽 121 ' 至少有一条槽边相互平行。
拼接混凝土模板时，在两块相互垂直搭接的混凝土模板 10a 的搭接处放置角板 10 ' ，角板 10 ' 的第一板 11 ' 和第二板 12 ' 分别贴合在两块混凝土模板 10 ' 的外表面上，然后将两个锁舌 23 ' 分别卡入混凝土模板 10a 上的快接槽 11a 内，旋转螺母 22 ' 使锁舌 23 ' 紧紧卡在快接槽 11a 内。这样，在混凝土模板 10 ' 的内表面所围成的型腔内浇筑混凝土，待混凝土成型后，反向旋转螺母 22 ' 使锁舌 23 ' 从快接槽 11a 内脱开，然后将混凝土模板一块一块拆下来即可。
本发明通过螺杆 21 ' 和螺母 22 ' 使锁舌 23 ' 紧卡在快接槽 11a 内，可提高紧固度。由于角板 10 ' 上开有第一槽 11 ' 和第二槽 12 ' ，这样可根据两块相互垂直搭接的混凝土模板的搭接处的角部安装位置，通过第一槽 11 ' 和第二槽 12 ' 相应地调整角板的位置，例如：两块相互垂直搭接的混凝土模板 10a 上的快接槽 11a 对齐在一起、相互错开或者相互垂直时，都能通过扣件装置将两块混凝土模板 10a 固定在一起，本发明具有较高的通用性，适用于多种规格的混凝土模板 10a 来拼接成多种形成的型腔，可提高装卸效率。
