Description

The eccentric lifting of sectional lifting rail scaffold

The utility model relates to a kind of building operations attached lift scaffold.

Known existing attached lift scaffold, support body contain four layers of construction level height, and weight is big.

The purpose of this utility model provides a kind of and contains three layers of construction level height, by plant produced, can assemble or half assembling the eccentric lifting of sectional lifting rail scaffold entirely in the building site assembling.During full the assembling, with main frame, crane span structure, lifting gear, anti-dumping anti-drop device assembling lifting structure part with vertical position welding, steel typing scaffold floor, is assembled the scaffold part.Except that the lifting structure part was identical, its scaffold partly adopted conventional steel tube fastener and bamboo wood scaffold floor when partly assembling.During segmentation, use two to four main frames, scaffold in the middle of one to three group of crane span structure is formed each side uses one group of cantilever crane span structure to form one section scaffold altogether, with adjacent another section scaffold sectional lifting, and also can two sections whole liftings.Become a kind of combined and instant, the attached lift scaffold of construction safety.

The purpose of this utility model is to realize like this.Promote the place, seat in the plane at each the main frame of a welding fabrication is set, and be divided into one two three joints, internode ties with the flange valve snail and connects, its inboard vertical bar, be again guide rail, remaining standpipe, steel scaffold floor, pull bar, lifting appliance, anti-dumping anti-drop device, crane span structure are conventional member, crane span structure is installed in the both sides of main frame bottom one joint, and the cantilever crane span structure is installed in the main frame outside, two ends.Vertical rod is installed in the crane span structure top, scaffold floor is formed one section lifting false work.Attached wall is overhead to be fastened on the structure side bar with through-wall bolt, and it respectively is equipped with a directive wheel bearing up and down, and guide wheel is enclosed within the anti-dumping lifting of can leading of main frame medial shaft in the vertical rod inner chamber.The overhead middle part of attached wall is equipped with anti-tenesmus locking device bearing, has the anti-fall suspension rod that is fixed in the inboard vertical rod of main frame to pass on its center line, forms anti-tenesmus structure.Reaching on the intensity layer side bar, each attached wall frame about being equipped with, the extension motor hoist in the left side, the extension in the right two wire rope tails of rope, forms to walk two eccentric Hoisting System.Formed that attached wall is overhead to be installed on the side bar of double-layer structure up and down that reaches intensity, scaffold with bottom attached wall frame and about two pairs of pull bars be installed on the side bar of double-layer structure up and down that reaches intensity, the anti-dumping anti-drop device is installed in the attached wall self-lifting scaffold frame system of attached wall on overhead.

Owing to adopted such scheme, its main frame, crane span structure, standpipe, scaffold floor, attached wall be overhead all to become stressed clear and definite structural member, can carry out theory by existing Code for design of steel structures calculates, be adapted to plant produced, reach standardization, assemblingization, tool and alleviate the purpose of lifting hand frame deadweight, simple in structure.
