| English to Chinese: Telescoping Shoring Post
Detailed field: Mechanics / Mech Engineering | Source text - English
TELESCOPING SHORING POST
FIELD OF THE INVENTION
[0001] The present application relates to a shoring post, in particular to a telescoping shoring post used in systems used for construction.
BACKGROUND TO THE INVENTION
[0002] In typical construction systems, a shoring post is used to help support objects, usually a ceiling or roof. With varying heights of ceilings, it is obviously beneficial to have a shoring post that capable of being quickly adjusted from one height to another, while at the same time ensuring a safe work environment for all workers.
[0003] Truss systems, such as those outlined in US Patent No. 6,116,567 exist, and involve screw jacks that rotate around the post to adjust the height of the post. While this is fine for small adjustments, if one wishes to extend or retract the post several feet, this could be very time consuming.
[0004] Another type of shoring post, described in Canadian Patent No. 2,249,921, is adjustable and can be used in a system or on their own. These types of shoring posts use a screw, while others of a similar type use a pin-type assembly. While both of these allow for the post to be extended quicker than a screw-jack type, they require the use of small screws and pins, which may not only be difficult to use, but are also easily lost.
[0005] A further prior art post is disclosed in US Patent No. 5,653,415 to Peri GmBH. The ‘415 post can be adjusted using pins for quick adjustment to the approximate height, and then a fine adjustment means. The problem with pins is that they can easily be lost and are an extra component that is required when erecting/disassembling the post.
[0006] There remains a need for a telescopic shoring post that can be quickly adjusted from one position to another.
[0007] There also remains a need for a shoring post of simpler design, with significantly fewer pieces involved.
SUMMARY OF THE INVENTION
[0008] The present invention overcomes the deficiencies of the prior art by providing a shoring post, comprising a hollow outer leg, a plurality of slots along the length of the outer leg, an inner leg dimensioned to fit within the outer leg, a tongue plate welded to one end of the inner leg, the tongue plate including a plurality of tongue members, wherein the inner leg may be rotated within the outer leg from a first position where the tongue members are fully within the outer leg, and a second position where the tongue members extend through the slot, locking the inner leg in position relative to the outer leg.
[0009] Additionally, the preferred embodiment of the shoring post includes an adjusting screw assembly, an adjusting handle, and a plurality of support pins, where the screw assembly is used for fine adjustments to the length of the post. There is also a lower outer leg at the opposite end of the screw assembly. Another addition to the preferred embodiment includes a plurality of grooves along the length of the inner leg and the outer leg.
[0010] The present application therefore provides a telescoping post shore comprising: an outer tube; a plurality of slots disposed longitudinally along said outer tube; an inner tube; at least one tongue member affixed to said inner tube and projecting from said inner tube, said at least one tongue member configured to be received by said plurality of slots; wherein said inner tube and at least one tongue member are dimensioned to slide within said outer tube and said inner tube and at least one tongue member can be rotated within said outer tube to engage said at least one tongue member with at least one of said plurality of slots.
[0011] Other aspects and advantages of the device will become apparent from the following Detailed Description and the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS

伸缩式支撑柱
技术领域
本申请涉及一种支撑柱，特别是，本申请涉及一种在用于建筑施工的系统中使用的伸缩式支撑柱。
背景技术
在典型的建筑施工系统中，支撑柱用于帮助支撑物体，通常是天花板或屋顶。在天花板高度是变动的情况下，具有一种能够快速地从一个高度调整到另外一个高度、同时能够为所有工人确保安全的工作环境的支撑柱显然是十分有利的。
桁架系统，如在美国专利US 6116567所列出的，出现并涉及了螺旋千斤顶，所述螺旋千斤顶能够围绕柱旋转以调整柱的高度。尽管该结构对于小的调整是可以的，但是如果希望将柱伸长或收缩几英尺的话，该结构将会非常耗时间。
在加拿大专利CA 2249921中描述的另一类型的支撑柱是可调整的，并且能够被用在系统中或者独立使用。这些类型的支撑柱使用螺钉，而其它近似类型的支撑柱使用销式组件。尽管这两种类型的支撑柱都能够比螺旋千斤顶更快地使柱伸长，但是它们需要使用小的螺钉或销，这些小螺钉或销不但使用起来困难，而且容易丢失。
另一种现有技术的柱被公开在授予皮瑞股份有限公司（Peri GmBH）的美国专利US 5653415中。’415中的柱可以使用销来调整以快速调整到一个近似的高度，并随后利用精细调整手段。该使用销的问题是：销容易丢失，并且这些销是在立起/拆卸柱时需要的一个额外构件。
由此，需求一种能够快速从一个位置调整到另外一个位置的伸缩式支撑柱。
而且，还需求一种具有简单设计、涉及非常少的零件的支撑柱。
发明内容
本发明通过提供如下所述的一种支撑柱来克服现有技术中的缺点，所述支撑柱包括：中空的外腿；沿着所述外腿长度设置的多个槽缝；内腿，尺寸制作成适配在所述外腿中；舌板，焊接到所述内腿的一端，所述舌板包括多个舌件，其中所述内腿可以在所述外腿中从第一位置旋转到第二位置，在第一位置所述舌件完全处于外腿内，在第二位置所述舌件延伸穿过槽缝、将所述内腿相对于所述外腿锁定到位。
另外，支撑柱的优选实施例包括调整螺钉组件，调整手柄，和多个支持销，其中螺钉组件用于对柱的长度进行精细的调整。在螺钉组件的相反端还设有下外腿。优选实施例的另一个附加的特征是，包括沿内腿和外腿的长度的多个槽。
因此，本发明提供一种伸缩式支撑柱，包括：外管；沿着所述外管纵向设置的多个槽缝；内管；至少一个舌件，固附到所述内管并且从所述内管突出，所述至少一个舌件构造成被所述多个槽缝接纳；其中，所述内管和所述至少一个舌件的尺寸被构造成可以在所述外管内滑动，并且所述内管和所述至少一个舌件可在所述外管中旋转，以便使所述至少一个舌件与所述多个槽缝中的至少一个接合。
该装置的其它方面和优点将从下面详细描述和附图中变得显而易见。
