Description

爬架桁架体系的可调节式斜腹杆 技术领域
本申请涉及爬架桁架技术领域，具体为一种爬架桁架体系的可调节式斜腹杆。
背景技术
因为桁架结构是爬架的组成部分，所以所有爬架公司的技术都会涉及到相关内容；市面上主要有两种形式：
第一种就是自成桁架体系构件，可以解释为本身就是桁架结构，当安装在爬架侧立面时，爬架就会具备一定的水平结构性能；该构件的优点就是生产加工简单、规格少，通用性强，可批量生产；但是缺点就是单体重量大，立面跨度小，所建立的桁架体系稳定性不足；
第二种就是利用不可调节的斜腹杆安装在主龙骨和大横杆相交点的组装构件，从附着点的位置成八字型开始布置，上下连接形成桁架结构；该结构的有点就是生产简单，运输方便，单体重量小，成本低、结构性能优越；缺点就是规格众多，通用性差。
发明内容
针对上述存在的技术不足，本申请的目的是提供一种爬架桁架体系的可调节式斜腹杆，实现斜腹杆长度的可调性，降低多种规格的使用，提高通用性。
为解决上述技术问题，本申请采用如下技术方案：
本申请提供一种爬架桁架体系的可调节式斜腹杆，该斜腹杆呈交叉式设于桁架本体上，该斜腹杆包括方形的母管和嵌套在所述母管内的方形的子管，所述母管内设有用于限制所述子管相对于所述母管轴向位移的限位机构，所述母管与所述子管相远端均开设有与桁架本体相固定的安装孔；
所述限位机构包括固定于所述母管内的第一定位块、螺纹装配在所述第一定位块上的螺杆以及螺纹装配在所述螺杆上的第二定位块；
所述母管的一对侧壁上开设有腰型槽，所述子管的一对侧壁上开设有若干个等距分布的调节螺纹孔；
当所述子管插接在所述母管内时，靠近所述子管插入端的调节螺纹孔内螺纹装配有抵紧在所述第二定位块上的第一螺栓，所述子管通过第一螺栓与所述第二定位块的抵紧实现轴向限位。
优选地，当所述子管插接在所述母管内时，位于所述腰型槽内的所述调节螺纹孔内螺纹装配有螺栓组件；
所述螺栓组件包括贯穿于所述母管和所述子管的第二螺栓和螺纹装配在所述第二螺栓上的螺母，所述第二螺栓的头部与所述螺母分别抵紧在所述母管的一对侧壁上。
优选地，所述母管的一对侧壁上开设有供所述第一定位块固定的定位孔，该定位孔位于所述安装孔与所述腰型槽之间，且靠近所述腰型槽。
优选地，所述第一定位块为长方体，所述第一定位块上设置有与所述定位孔相对应的内螺纹孔，所述第一定位块通过第三螺栓固定在所述母管内，所述第一定位块的四个侧壁分别与母管的四个内壁相贴合；
所述第二定位块为长方体，第二定位块的四个侧壁分别与子管的四个内壁相贴合，所述第二定位块上还开设有供所述第一螺栓抵紧的环形限位槽，所述环形限位槽的两个侧面与所述第一螺栓相切。
优选地，所述定位孔的内径小于所述调节螺纹孔的内径，所述腰型槽的宽度与所述调节螺纹孔的内径相同。
优选地，所述母管为50mm×50mm×4mm壁厚的方形管，所述子管为40mm×40mm×3.75mm壁厚的方形管，所述调节螺纹孔规格为M16。
优选地，所述螺杆的两端均开设有内六角孔。
本申请的有益效果在于：本申请实现了斜腹杆长度的可调性，使得其能够使用更多的安装场景，提高了通用性；同时该斜腹杆利用腰型槽的调节结构，能够实现一定范围内的尺寸的连续调节，而非点式的调节，其更能够使用安装需求，特别是能够应对桁架本体微量变形下的安装；
此外虽然腰型槽的设置具有更广泛的调节范围，但是腰型槽的开设会在一定程度上降低母管的强度，而其内的限位机构则在完成对子管限位的同时，还能启到对母管强度的加强，其相当于在母管内植入了加强筋，利用螺杆与子管和母管的固定，从而补偿因开设腰型槽而产生的强度降低的情况。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例：
如图1所示，为本申请提供的可调节式的斜腹杆002在爬架桁架体系的桁架本体001上的安装情况，其安装按照交叉的方式进行，即折线状的走向；
结合图2，该斜腹杆002包括母管1和嵌套在所述母管1内的子管2，母管1为50mm×50mm×4mm壁厚的方形管，子管2为40mm×40mm×3.75mm壁厚的方形管，其中50mm×50mm和40mm×40mm代表子母管外圈的长和宽；
所述母管1内设有用于限制所述子管2相对于所述母管1轴向位移的限位机构(在本实施例中，轴向特指子管2和母管1的长度方向)，所述母管1与所述子管2相远端均开设有与桁架本体001相固定的安装孔8，该安装孔8与现有的斜腹杆上的安装孔一样，其安装方式与现有的相同，即通过安装孔8将斜腹杆002固定在桁架本体001上的竖向和横向构件节点的连接板上；
所述限位机构包括固定于所述母管1内的第一定位块3、螺纹装配在所述第一定位块3上的螺杆5以及螺纹装配在所述螺杆5上的第二定位块4；
所述母管1的一对侧壁上开设有腰型槽11，所述子管2的一对侧壁上开设有若干个等距分布的调节螺纹孔21，腰型槽11的宽度与调节螺纹孔21的内径相同，调节螺纹孔21规格为M16；
当所述子管2插接在所述母管1内时，靠近所述子管2插入端的调节螺纹孔21内螺纹装配有抵紧在所述第二定位块4上的第一螺栓7，所述子管5通过第一螺栓7与所述第二定位块4的抵紧实现轴向限位。
进一步的结合图3，当所述子管2插接在所述母管1内时，位于所述腰型槽11内的所述调节螺纹孔21内螺纹装配有螺栓组件6；
所述螺栓组件6包括贯穿于所述母管1和所述子管2的第二螺栓和螺纹装配在所述第二螺栓上的螺母，所述第二螺栓的头部与所述螺母分别抵紧在所述母管1的一对侧壁上。
结合图3和图4，所述母管1的一对侧壁上开设有供所述第一定位块3固定的定位孔12，该定位孔12位于所述安装孔8与所述腰型槽11之间，且靠近所述腰型槽11，定位孔12的内径小于所述调节螺纹孔21的内径；
所述第一定位块3为长方体，所述第一定位块3上设置有与所述定位孔12相对应的内螺纹孔，所述第一定位块3通过第三螺栓固定在所述母管1内，所述第一定位块3的四个侧壁分别与母管1的四个内壁相贴合；
所述第二定位块4为长方体，第二定位块4的四个侧壁分别与子管2的四个内壁相贴合，所述第二定位块4上还开设有供所述第一螺栓7抵紧的环形限位槽41，所述环形限位槽41的两个侧面与所述第一螺栓7相切，即如图4所示，第一螺栓7贴合在环形限位槽41的两个侧壁上，进而实现对子管2的轴向限位；
综上可以看出，限位机构实际上形成了类似与丝杠滑块的结构，即通过螺杆5的转动进而带动第二限位块4的位置变动，进而适应子管2插入母管1内长度的变化，为了方便转动螺杆5，螺杆5的两端均开设有内六角孔。
结合图5和图6，该两个附图给出两种安装情况，可以看出，螺杆5通过第一定位块3被固定在母管1内，当子管2插入时，利用第二定位块4又使得螺杆5与子管2相固定，最终使得子管2和母管1实现连接，从而限制子管2的轴向位移，同时利用腰型槽11的存在，在位于腰型槽11内的调节螺纹孔21上安装螺栓组件6，使得子管2又进一步的与母管1实现连接，提高了二者的连接性；此外考虑到腰型槽11的开设会在一定程度上降低母管1的强度，结合图5，可以看出在子管2插入端到第一定位块3之间的这一段，由于腰型槽11的存在，该部分存在中空，因此在该段，其强度会受到降低，而限位机构的存在则恰恰补偿了该部分的缺陷；即在图中可以看出，在该段穿插了螺杆5，并利用第一定位块3和第二定位块4实现固定，进而产生了类似于植筋的作用，从而补偿因开设腰型槽11而产生的强度降低的情况。
使用时，使用者可按照以下两种方式进行调节安装：
其一，在桁架本体001搭建完成一部分后，并开始要安装斜腹杆002时，事先测量好斜腹杆002安装的位置，进而确定出斜腹杆002需要的长度，在安装斜腹杆002之前将其长度确定好；即根据测量的尺寸，在母管1内将第二定位块4的位置调整好(利用带有六角扳手的支杆插入螺杆5的内六角孔内进行调节)，然后插入子管2，先利用第一螺栓7将子管2和母管1连接上，此时不需 要将第一螺栓7紧固，然后将整个斜腹杆002安装在桁架本体001上，最后再对第一螺栓7进行紧固，并在位于腰型槽11内的调节螺纹孔21上安装螺栓组件6；
其二，在桁架本体001搭建完成一部分后，并开始要安装斜腹杆002时，可先行将子管2安装在桁架本体001上，然后将母管1插上，使得母管1的安装孔8对准安装位置，利用带有六角扳手的支杆插入螺杆5的内六角孔内，转动螺杆5即可实现第二定位块4位置的变动，使其与靠近子管2插入端的调节螺纹孔21相对应，即可安装第一螺栓7，最后再对母管1的安装孔8进行固定，并在位于腰型槽11内的调节螺纹孔21上安装螺栓组件6即可。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
