Abstract
The shoring includes a pair of fixed frames opposed to each other and a pair of collapsible reinforcing frames disposed between both ends of the fixed frames, the reinforcing frames each having collapsible baluster struts whose base ends are pivotally connected between end portions of the fixed frames, a support rod whose base end is pivotally connected to an intermediate position of the baluster struts, and plural braces whose base ends are pivotally connected to end portions of the fixed frames and whose front ends are mounted vertically slidably to the support rod.
Claims15
A shoring comprising a pair of fixed frames opposed to each other and a pair of collapsible reinforcing frames disposed between both ends of said fixed frames, said reinforcing frames each comprising:
- collapsible baluster struts whose base ends are pivotally connected between upper end portions of said fixed frames;
- a support rod whose base end is pivotally connected to an intermediate position of said baluster struts and which is suspended downward;
- first and second guides slidable on said support rod in opposite directions;
- a pair of first braces, each of said first braces having one end pivotally connected to one of said upper end portions of said fixed frames and another end pivotally connected to said first guide;
- a pair of second braces, each of said second braces having one end pivotally connected to one of said lower end portions of said fixed frames and another end pivotally connected to said second guide.
A shoring comprising a pair of fixed frames opposed to each other and a pair of collapsible reinforcing frames disposed between both ends of said fixed frames, said reinforcing frames each comprising:
- collapsible baluster struts whose base ends are pivotally connected between upper end portions of said fixed frames;
- a support rod whose base end is pivotally connected to an intermediate position of said baluster struts and which is suspended downward;
- and
- four braces whose base ends are pivotally secured to upper and lower ends of said fixed frames and whose front ends are connected to said support rod vertically movably;
- the support rod being formed by a channel steel having a vertical guide channel, a first guide being fitted vertically movably on a back of said channel steel, a second guide being fitted vertically movably in said guide channel, and either front ends oftwo upper said braces or front ends of two lower said braces are pivotally connected to one of said first and second guides.
A shoring comprising a pair of fixed frames opposed to each other and a pair of collapsible reinforcing frames disposed between both ends of said fixed frames, said reinforcing frames each comprising:
- collapsible baluster struts whose base ends are pivotally connected between upper end portions of said fixed frames;
- collapsible horizontal support frames whose base ends are pivotally connected between lower end portions of said fixed frames and which are in parallel with said baluster struts;
- a support rod hinged between an intermediate position of said baluster struts and an intermediate position of said horizontal support frames;
- a guide fitted vertically slidably on the outer periphery of the upper portion of said support rod;
- and
- two braces hinged between both sides of said guide and the lower ends of said fixed frames.
A shoring comprising:
- a pair of fixed frames spaced from each other, each of said frames including a first and second end;
- a pair of baluster struts, each of said baluster struts having a first end pivotally connected to one of said first ends of said fixed frames;
- a support rod having one end pivotally connected to said second ends of said baluster struts;
- a first guide slidable on said support rod;
- a second guide slidable on said support rod independently of said first slide and in opposite directions from said first guide;
- a pair of first braces, each of said first braces having one end pivotally connected to one of said first ends of said fixed frames and another end pivotally connected to said first guide;
- a pair of second braces, each of said second braces having one end pivotally connected to one of said second ends of said fixed frames and another end pivotally connected to said second guide.
