The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment 1
With reference to figure 1, Fig. 3 and Fig. 4, a kind of portable scaffold includes steel pipe 2 and the many ladders basically that cross bar constitutes behind 2 preceding steel pipes 1 and 2, and cross bar comprises left cross bar 3, right cross bar 4 and front rail 5.
The preceding steel pipe 1 that many left cross bars 3 will be positioned at the left side and back steel pipe 2 are welded into the long ladder in a left side with the spacing of 600mm, are spaced apart 500mm between two left cross bars 3; Be positioned at the preceding steel pipe 1 of left cross bar 3 distances and the back steel pipe 2 terminal 250mm of being at the terraced two ends of length, a left side, this section is left terraced connecting portion.
The preceding steel pipe 1 that many right cross bars 4 will be positioned at the right and back steel pipe 2 are welded into right long ladder with the spacing of 600mm, are spaced apart 500mm between two right cross bars 4; Be positioned at the preceding steel pipe 1 of right cross bar 4 distances and the back steel pipe 2 terminal 250mm of being at the terraced two ends of right length, this section is right terraced connecting portion.
Many front rails 5 are with long ladder in a left side and right long terraced preceding steel pipe 1 vertical being welded to connect, and front rail 5 is also perpendicular to left cross bar 3 and right cross bar 4; The long ladder in a left side is 800 mm with spacing between the right long ladder, is spaced apart 500 mm or 1000 mm between two front rails 5, and preceding steel pipe 1 end of front rail 5 distances at steel pipe 1 two ends is 250mm before being positioned at.
Left side cross bar 3 is positioned at same plane with right cross bar 4; Front rail 5 is positioned at same plane with left cross bar 3 with right cross bar 4; Preceding steel pipe 1 is 3000-5000mm with the length of back steel pipe 2.
The removable connection of steel pipe after having at least 1 rear transverse rod 9 to incite somebody to action terraced basically 2.
The left terraced connecting portion and the right terraced connecting portion of basic ladder have cross-perforating 10; Also include cover pipe connections 6; Cover pipe connections 6 has at least 2 spacings and is connected perforation 60 with the cross-perforating 10 corresponding sleeve pipes of basic terraced terminal part; 2 alignment prolong and are connected with the back steel pipe with the preceding steel pipe 1 of 2 or a plurality of basic ladders; Cover pipe connections 6 is set in the left terraced connecting portion and the right terraced connecting portion of 2 basic ladders that connect, and bolt 61 inserts the cross-perforating 10 that the sleeve pipe that overlaps pipe connections 6 connects perforation 60 and passes left terraced connecting portion or right terraced connecting portion, and connecting first basic ladder of the top, back is the top ladder.
The last end of top ladder has L shaped hook (7); One end of L shaped hook (7) can laterally be directly welded on the ladder of top; In the present embodiment; Use for convenient, the last terminal transverse weld of top ladder or the removable hook pipe 8 that is connected with, hook pipe 8 has been horizontally set with hook fixing hole 80; L shaped hook 7 has hook horizontal perforation 70, and L shaped hook 7 one ends penetrate hook pipe 8 hook fixing holes 80 interior and that pass on the hook pipe 8 with bolt 71 fixedly becomes the scalable hook with hook horizontal perforation 70 backs of linking up with on 7 with nut.
Specifically with reference to figure 4; Engineering so that wallboard to be installed on body of wall is an example; Select 2 ladders basically according to the height of body of wall; The height sums that require 2 basic ladders are a little more than the body of wall height, vertically place the 1st ladder basically in that the construction body of wall is other earlier, the sleeve pipe that passes cover pipe connections 6 at the upper end of this basic ladder terraced connecting portion in a left side and right terraced connecting portion slip joint casing connector 6 and with bolt 61 is connected bore a hole 60 with preceding steel pipe 1 with after cross-perforating 10 on the steel pipe 2 make firm the connection; Use lifting gear to rise the 2nd ladder basically; The left terraced connecting portion and the right terraced connecting portion of this basic terraced lower end are inserted into respectively in the cover pipe connections 6 that has been connected on the 1st basic ladder; And with the sleeve pipe that bolt 61 passes cover pipe connections 6 connect steel pipe 1 before perforation 60 and the 2nd the basic ladder with after cross-perforating 10 on the steel pipe 2 make firm be connected fastening; Just prolonging along the body of wall alignment of such 2 basic ladders connects into; Scaffold, the basic ladder that is positioned at the scaffold bottom are the bottom ladder, and the basic ladder that is positioned at scaffold top is the top ladder; Ladder and the fair mutually horizontal removable coupling hook pipe 8 in position in body of wall top at the top; The end that hook 7 is had hook hole 70 penetrates in the hook pipe 8, regulates distance that hook 7 penetrates hook pipe 8 and makes the other end of hook 7 stretch out the top ladder tightly to hang on the top of a wall or the crossbeam, and the hook fixing hole 80 that passes on the hook pipe 8 with bolt 71 at last is also fastening with nut with the hook hole 70 on the hook 7; The upper end of scaffold is fixed on the top of a wall or the crossbeam by hook 7, and the lower end of scaffold is by ground supports.
For making scaffold more firm, the middle part can adopt connector and support bar with basic ladder or top ladder removable fixed connection of connector with the metope of constructing.
For making scaffold be easy to move; Can be before the assembling scaffold two channel-section steels 12 of parallel placement along the ground of body of wall in advance; Bottom face welding 50 * 50mm cushion block 11 of the preceding steel pipe 1 of ladder and back steel pipe 2 in the bottom; End face with the bottom ladder is positioned over together with cushion block 11 in the groove of channel-section steel 12 again, and channel-section steel 12 is supporting scaffold on ground.
During construction, the people climbs construction location by long ladder in a left side or right long ladder, and the part (for example wallboard) of constructing can be by the side direction handling of scaffold to construction location; Can press vertically operation side by side of metope, after one section wall construction is accomplished scaffold a plurality of constructors that stand respectively up and down; Need not to remove scaffold; After the constructor leaves scaffold, promote scaffold along channel-section steel 12 it is moved to other construction locations, carry out the constructing operation of next section metope; After whole wall construction is accomplished, remove hook 7 and top ladder respectively by above-mentioned opposite operation.
Present embodiment has characteristics easy to install and use, can effectively reduce the engineering quantity that scaffolds erecting, and has reduced construction costs, and efficiency of construction is high.
With reference to figure 2; The difference of present embodiment and embodiment 1 is: the last end of top ladder has L shaped hook 7; Have a plurality of hook horizontal perforations 70 on the L shaped hook 7, an end of L shaped hook 7 laterally is posted by on the terminal preceding steel pipe of top ladder 1 and the back steel pipe 2 and with bolt 71 and passes the cross-perforating 10 of hook horizontal perforation 70 and top ladder end and use nut screwing clamping.The method for using of present embodiment is identical with embodiment 1.
