Further, on the downside of the front end of described lower truss, pedal is installed.
Preferably, the quantity of described pedal is at least one.
Further, described upper truss, lower truss, left truss and right truss are arranged on described steel case arch by temporary connection.
Further, described temporary connection is made up of steel plate and set square, and described Interal fixation is on described steel case arch, and fixed triangle plate on described steel plate, described upper truss, lower truss, left truss and right truss and described set square are fixed.
Preferably, the quantity of described set square is two pieces.
The present invention has the following advantages:
Structure of the present invention is simple, mounts and dismounts all very convenient; The present invention can recycle, and greatly reduces the input of cost; The invention solves original operation platform and set up difficulty greatly, the problem of poor stability, be directly installed on steel case arch, do not destroy steel case and encircle this body structure; The present invention simultaneously when mounted, can complete on the ground, substantially increase safety during operation like this.
Accompanying drawing explanation
The structural representation of the combined type working platform that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the partial enlarged drawing of Figure 1A part.
Detailed description of the invention
Below in conjunction with drawings and embodiments, the present invention is further detailed explanation.
See figures.1.and.2, embodiments provide a kind of combined type working platform, this working platform is fixedly mounted on steel case arch.This working platform comprises truss 1, lower truss 2, left truss 3 and right truss 4.Upper truss 1 is welded by square steel, and lower truss 2 adopts Type of Welding to form by square steel and round steel, and left truss 3 and right truss 4 are welded by equal leg angle respectively.Upper truss 1 is fixed by the first bolt 5 and left truss 3 and right truss 4, in lower truss 2 and left truss 3 and right truss 4 any one hinge, lower truss 2 and right truss 4 hinge in the present embodiment, and by the fixing lower truss 2 of the second bolt 6 and the connection between left truss 3 and right truss 4.Left truss 3 and side, right truss 4 front end are provided with multiple safety fence 7.Left truss 3 and right truss 4 are provided with multiple cat ladder railing 8.Cat ladder railing 8 convenient construction personnel take action on left truss 3 and right truss 4.Be provided with ten pedals 9 on the downside of the front end of lower truss 2, pedal 9 can convenient construction personnel be taken action on lower truss 2, and the material of pedal 9 is checkered steel plate, and checkered steel plate has anti-skidding function.Upper truss 1, lower truss 2, left truss 3 and right truss 4 are arranged on steel case arch by temporary connection.Temporary connection is made up of steel plate and two pieces of set squares, and Interal fixation, on steel case arch, steel plate is fixed two pieces of set squares, and upper truss 1, lower truss 2, left truss 3 and right truss 4 and set square are fixed.
During installation, steel case arch lifted before, the embodiment of the present invention is arranged on a steel case arch abutment head, and by whole steel case arch abutment head circumference around.Upper truss 1 and left truss 3 and right truss 4 first bolt 5 are fixed, lower truss 2 and right truss 4 hinge, the fixing lower truss 2 of the second bolt 6 and the connection between left truss 3 and right truss 4.Another one steel case arch repeats above-mentioned steps, when two steel casees arch lifting laggard row that puts in place closes up, the two ends of two steel case arches respectively has the combined type working platform of an embodiment of the present invention, naturally be combined into an integral frame like this, form a closed structure, combined type working platform installs, and constructor can the dynamic and work in the enterprising every trade of working platform.
During dismounting, first wire rope one end of dismounting is fixed on the termination on the left of lower truss 2, the other end is fixed on loop wheel machine gib head; Then second bolt 6 of lower truss 2 one end of dismounting, because right truss 4 and lower truss 2 hinge, so can utilize wire rope lower truss 2 to be placed plumbness; Finally wire rope is fixed on upper truss 1 and loop wheel machine, dismantles other bolt, then the combined type working platform of the embodiment of the present invention is hung to ground, prepare the installation of next station.
The structure of the embodiment of the present invention is simple, mounts and dismounts all very convenient; The embodiment of the present invention can be recycled, and greatly reduces the input of cost; The embodiment of the present invention solves original operation platform and sets up difficulty greatly, the problem of poor stability, is directly installed on steel case arch, does not destroy the quality of steel case arch own; The embodiment of the present invention when mounted simultaneously, can complete on the ground, substantially increase safety during operation like this.
It should be noted last that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
