The specific embodiment

Below in conjunction with drawings and Examples the utility model is done detailed introduction:

As shown in the figure, this externally-hanging type exterior wall scaffold mainly comprises the crane span structure 1 and the work layer 2 that are fixed in the house outer wall, and reach up and down two work layer 2 outsides install the railing of using as construction protection 3 additional at crane span structure 1 top; Railing 3 one sides at each layer are linked with the safety net of the integral protection of personnel and material etc. being used to facilitate 4, and after crane span structure 1 top outer was installed railing 3, its top got final product construction operation layer 2 of double as; Leaning on building one side-lower setting in crane span structure 1 bottom is the protective fence 5 of skeleton with shaped steel, hangs safety net 4 along protective fence 5 total lengths and mixes constructional materials and the security protections of instrument in construction such as earth is template used, support to guarantee cast; Each construction operation layer 2 between two adjacent crane span structures 1 is provided with the protective door 6 that can open and close and can doublely do railing 3 to the inside, strides the usefulness of the passage of crane span structure 1 when being in same level with convenience adjacent two; This crane span structure 1 has also been installed to adapting to the auxiliary support body 7 perpendicular to the construction of the concavo-convex wall face of building; In the top and the bottom, both sides, bearing place of this crane span structure 1 intensity of promising raising crane span structure 1 and the reinforced steel 8 of safety are set; Be provided with the pull-shaped A-frame 9 of extension of supporting form in this crane span structure 1; Work layer 2 bed board places respectively establish one and can be used for the hole 10 that the levels personnel pass through in each crane span structure 1.

As Fig. 3, shown in Figure 4, for adapting to construction perpendicular to the concavo-convex wall face of building (as balcony etc.), crane span structure 1 is installed in the outside of building projection certain distance, position according to recess is provided with the construction operation platform of auxiliary support body 7 as recess, described auxiliary support body 7 is by flat rod 23, transverse link 24, vertical vertical rod 25, addition rod 26 and bed board 27 are formed, flat rod 23 is chosen needed length from each aspect up and down of main crane span structure, horizontally connect between this transverse link 24 and the flat rod 23, being vertical between this flat rod 23 and transverse link 24 and the vertical vertical rod 25 is connected, use bolt between the three respectively, place the addition rod 26 more than at least one in each work layer 2 bottoms; See that from side direction auxiliary support body 7 bottoms that link to each other with crane span structure 1 of formation lay bed board 27 in the back that links to each other, make it to become with crane span structure 1 can the while lifting and the construction operation platform of equivalent effect.

As shown in Figure 5, for improving the intensity and the safety of crane span structure 1, in the top and the bottom, both sides of crane span structure 1 bearing reinforced steel 8 is set, this reinforced steel 8 is taken with overlapping the tying up of bolt with the main longitudinally girder steel of crane span structure 1, and the length of reinforced steel 8 is decided with the stressing conditions of crane span structure 1; Under crane span structure 1 span or stressed bigger situation, the way that gaily decorated basket pull bar 30 also can be set in crane span structure 1 both sides guarantees the safety of crane span structure 1, specific practice is as follows: excentral certain distance of bearing and two bottom sides at both sides, crane span structure 1 bearing top reinforced steel 8 are provided with the fulcrum 31 that can be connected gaily decorated basket pull bar 30 near span centre respectively with the place, end, adjusting by turnbuckle 32 is to adjust the stressing influence of crane span structure 1 middle part and end, the rigidity and the security performance of raising crane span structure 1.

As shown in Figure 6, the pull-shaped A-frame 9 of described extension is made of base crossbeam 11, vertical rod 12, diagonal member 13, be provided with a rotating movable structure 14 of hanging with vertical rod 12 joints on this diagonal member 13, have to play at an end of base crossbeam 11 slidingly to rise guiding and is connected and the upper and lower opening interior angle has the arcuation steel tank 16 that acts on along sliding with guide rail 15; There is an iron bolt 18 for starting device drag hook 17 usefulness at the middle part of base crossbeam 11, cross bar 20 is offered rectangle first hole 22 that supplies lifting slide fastener 19 to pass above iron bolt 18, offer rectangle second hole 21 that supplies lifting slide fastener 19 to pass in the inside of diagonal member 13, make things convenient for drag hook 17 to stretch into and hook iron bolt 18 from the top.

As shown in Figure 7, for current convenient between convenient construction operating personnel levels, work layer 2 bed board places respectively establish one and can be used for the hole 10 that the levels personnel pass through in each crane span structure 1, and at the hole 10 places establish and can upwards open and close removable cover 28, establish 10 belows, hole can be for constructor's cat ladder 29 up and down.
