Description
Technical field
The present invention relates to building field, be specifically related to a kind of scaffold construction method for precast facade.
Background technology
Existing building scaffold is divided three classes, console mode scaffold, attaching scaffold and overhanging scaffold.Console mode scaffold is due to height restriction, and flooring base be there are certain requirements, therefore be generally applied to median low structure.The investment of attaching scaffold is large, it is loaded down with trivial details to set up, therefore apply less.Overhanging scaffold is widely used in middle-high building.
In existing overhanging scaffold work progress, ubiquity need to be preset the problem points of fixture in body of wall, as disclosed in patent CN201288415Y " subsection gradual change overhanging type external scaffold for tall building ", its feature is, need to set in advance at the flooring of each floor the fixture of encorbelmenting in advance, and after pin hand is removed, default fixture cannot be recycled, cost of idleness.
Overhanging scaffold is executed man-hour requirement workman and is completed in the air and all set up task at height in addition, not only dangerous, and work efficiency is lower.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of scaffold construction method that construction period for precast facade is little, construction cost is low, safety factor is high.
For reaching above object, the technical scheme that the present invention takes is:
For a scaffold construction method for precast facade, comprise the following steps:
(1) fixed triangle frame: taking precast facade as unit reference block, in the precast facade equal intervals of the 1st layer of building, plural tripod is installed side by side, each tripod is fixed by 2 above extension wall screw and exterior walls;
(2) build gusseted support body: all tripods with together above drag link serial connection with row, drag link is fixedly connected with the right-angle side that each tripod is fixed on body of wall through fastener; The hypotenuse of adjacent two triangle supporting frames is with two above diagonal member reinforcement by connection, two of diagonal member is fixedly connected with two hypotenuses of adjacent two triangle supporting frames through fastener respectively, a diagonal member is arranged at gusseted support body inner side, another root diagonal member is arranged at the external side of triangular support bracket, and two diagonal members are cross-shaped; Now form firm gusseted support body in wall outer side.
(3) build transverse and longitudinal structure: the upper surface at gusseted support body is installed two load-bearing scaffold tubes that parallel, and with fastener, load-bearing scaffold tubes and each tripod is fastenedly connected respectively; Vertical rod outside the horizontal right-angle side of each tripod is installed vertically away from wall one end, fastening with fastener;
(4) installation foot hand springboard: pin hand springboard is laid successively to gusseted support body top, and circular arc recess and supporting foot hand pipe thread that pin hand springboard is four jiaos through bottom connect, and retain 5-10mm gap between adjacent pin hand springboard;
(5) guardrail board is installed: the epimere of same row's many outer vertical rods and hypomere are fixing through cross bar serial connection respectively, between cross bar and outer vertical rod, fixed by fastener, the perpendicular inner side of many outer vertical rod formation is provided with guardrail board, the bottom supporting of described guardrail board is in pin hand springboard, and guardrail board is connected fastening through HOOK BOLTS with cross bar; In guardrail inner side, baseboard is installed; At the two ends of gusseted support body, cross bar and guardrail board are installed with the same manner; So far 1 layer of scaffold built
(6) build second layer scaffold: same scaffold is built in repeating step (1)-(5) on the 2nd layer of precast facade of building.
(7) recycle: after the 1st layer of construction completes, utilize derricking gear by four jiaos of uniform stressed liftings of the 1st layer of scaffold, when steel cable to be lifted is tightened, unclamp after the extension wall screw being connected with exterior wall, the 1st layer of scaffold winched to the 3rd layer after again with hang wall screw retighten; The 2nd layer winches to the 4th layer with the same manner after completing construction, successively circulation.
Take after above technical scheme, beneficial effect of the present invention is:
(1) building of scaffold provided by the invention only need be at building the 1st, the 2 two-layer scaffoldings of building respectively, re-using derricking gear alternately upwards lifts by crane and reuses, the danger of having avoided high-altitude to build, save with respect to console mode and attaching scaffold material and the cost built, simplify build process, saved workload.
(2) scaffold in this programme, without the each floor embedded fixing component at building, only need be preset bolt hole on construction wall, without waste fixture, and little to damage of wall, body of wall is easily repaired.
