Description

Full assembling through bridge frame lifting rail scaffold

The utility model relates to a kind of lifting rail scaffold.

Known existing lifting false work all adopts the scaffold of routines such as steel pipe, fastener, bowl buckles, the wooden scaffold floor of bamboo to establish material and sets up, and belong to and establish engineering temporarily, and its theory is calculated as approximation method, and the support body dead weight is big.

The purpose of this utility model provides a kind of standard knots member by plant produced, be transported to the building site and be assembled into a kind of full assembling lifting false work with bolt connection mode, become a kind of construction equipment of construction enterprises, and itself weight is with fastener type or bowl fastening type scaffold weight reduction 30%.

The purpose of this utility model is achieved in that lifting false work is a group machine hoisting scaffold, promote the place, seat in the plane at each a vertical applied force main frame is set, four floor height are arranged, main frame is divided into one, two, three, four joints, by conventional scaffolding steel pipe, and the steel plate welding fabrication, internode has flange to connect with bolts assemblies, an angle steel lengthening frame is arranged at one joint bottom, is fastened on the structure side bar with through-wall bolt, and elevator is installed in a joint bottom.Front end with about two pull bar drawknots on the last layer structural beams, left and right sides erection bridge, two, three joint main frames are guide rail joints, it is by the double guide rail pipe of doing of two standpipes of wall one side.Four joints are top spreading joints, and its top outer has security protection to block bar.On the three layer construction side bar, promote the guiding i beam with fastening one of through-wall bolt, its front end with two pull bar drawknots on last layer structure side bar, the front end below has the suspension ring that the elevator fixed pulley is installed that the fixed pulley of elevator is installed, the elevator wire rope is walked two connections through this fixed pulley, form the stressed system that promotes, two directive wheels about the middle part of lifting guiding i beam is equipped with, form an attached wall supporting-point herein, on the four-layer structure side bar, with the fastening anti-fall guiding i beam of through-wall bolt, its front end has two to shore and be bearing on the substructure side bar downwards, and front center is installed controlled anti-dropping safety device down with bolt.Two directive wheels are installed about top, form another attached wall supporting-point herein, anti-dropping safety device down is controlled anti-tenesmus locking device, two lock dogs are arranged in its shell, two medial shafts of lock dog upwards have and are splay triangle teeth and can bite the anti-fall suspension rod of φ 30 round steel, lock dog has gathering sill that lock dog is moved up and down along gathering sill, there are two of stage clips the lock dog upper end, switch member is arranged at the bottom, be pulled on the fixed pulley with φ 6 round steel, controlled process is to break or promote the supporting-point damage and make fixed pulley lose hoist load when boom hoist cable, make φ 6 round steel lose pulling force simultaneously, under the promotion of two stage clips, two lock dogs walk downwards that a stroke is bitten φ 30 round steel and the generation of preventing tenesmus, play the security insurance effect, φ 30 round steel two ends car teeth, be fastened between two joint bottoms and the three joint tops with nut, vertically be installed on the center line of two guide rail pipes, when hoist load, promote fixed pulley and be in the upright position, through φ 6 round steel switch member is upwards backed down two lock dogs stroke that makes progress away and do not bite φ 30 round steel, two stage clips are in compressive state, promote or the decline state for normal, this process is a full-automatic process, the stressed crane span structure in bottom steel pipe steel plate welding fabrication, and be divided into one and two internode sheet crane span structure unit, last lower edge stull unit, last lower edge diagonal brace unit, the coupling bar unit winds up, can be assembled into an internode cantilever crane span structure after being transported to the building site, two, three, four internode freely-supported crane span structures, the lower edge counter-force of crane span structure point articulated main frame one joint bottom side to hinge on, wind up and be connected in a side at main frame one joint top with the coupling bar that winds up, forming crane span structure is hinged on the main frame, the most following two steps sealing scaffold floor of lower edge lay checkered steel plate welding forming on the crane span structure, can prevent that less object from weighing down scaffold, the crane span structure node place of winding up is welded with short stanchion, be used for detaining snapping with taking over the scaffold standpipe on crane span structure top, interior external scaffolding standpipe is welded into standard component with steel pipe, the place is welded with the scaffold floor supporting leg at the installation foot palm, the expanded metal lath scaffold floor of typing uses bolton on the scaffold floor supporting leg of standpipe, the length of scaffold floor replaces conventional big transverse tube to rib, the cross rib of scaffold floor replaces conventional little transverse tube, be welded with two articulated slabs on the frame of expanded metal lath scaffold floor inboard, there is a block plate net scaffold floor turnover panel to be hinged on this hinge plate by wall one side, retaining protection and operation scaffold floor in forming, this turnover panel can turn over and be placed on the scaffold floor, simple to operate, such structure has been cancelled the big transverse tube of conventional scaffold, little transverse tube, alleviated deadweight, with the whole shaping standardizations of the member of scaffold, be convenient to plant produced again.

Owing to adopted such scheme, its main frame, crane span structure, vertical rod, scaffold floor, attached wall frame all 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 support body deadweight, simple in structure.
