Description

From lifting false work

The utility model relates to the building operations scaffold, and particularly a kind of high-rise building building operations is used from the lifting exterior wall scaffold.

The construction of high-rise building agent structure and decoration of exterior wall generally must be set up scaffold.Traditional way is to set up full hall scaffold from ground, though this way can satisfy construction requirement, need expend a large amount of labours and scaffolding, the operating expenses costliness.

In order to reduce construction cost, a kind of way commonly used is to adopt climbing scaffold, and promptly scaffold is with the rising gradually of the architecture construction rising of climbing.China Patent No. 86203954 disclosed a kind of attached walls self Liftable type scaffold is commonly used one type, and it utilizes two pairs of attached wall supports to replace lifting mutually so that the lifting of a separate single Pin scaffold.Though this way can be carried out structure or decoration construction, be only applicable to the high-rise building of shear wall system, for a large amount of structures be frame system highrise building then in the use comparatively the difficulty.

Also have a kind of China Patent No. 93219468.0 disclosed mutual lifting exterior wall scaffolds, it is by coming independently single Pin scaffold in the middle of the lifting hanging Chain block on two adjacent fixing scaffolds, but like this repeatable operation with regard to the whole scaffolds of ascending, descending.Though this way is suitable for the highrise building of frame system, can only carry out the lifting of separate single Pin scaffold, can not accomplish integral body or burst lifting, and this point to be institute of present numerous construction enterprises generally expect.

The purpose of this utility model provides a kind of from lifting false work, and it can be applicable to the building of shear wall system or frame system effectively, accomplishes that integral body or sheet or single Pin rise and fall independently.

Described in the utility modelly a kind ofly comprise bearing post from lifting false work, level is installed in the little transverse tube of bearing post two sides, be installed in the big transverse tube that intersects with little transverse tube below the little transverse tube, and be installed in the scaffold tubes that intersects with little transverse tube above the little transverse tube, it also comprises and being connected with bearing post, wherein interior bar is a stock, outer bar is the I-shaped coupling bar of quarter butt, the hanger otic placode of installing in interior bar two sides of I-shaped coupling bar, and install on the bearing post upper strata, be shelved on sky crossbeam on the hanger otic placode connector of upper strata and install in bearing post lower floor, hang the ground crossbeam on lower floor's hanger otic placode connector; Described bearing post comprise wherein one group be vertically set on four steel standpipes of inboard four jiaos of two little transverse tube one ends and wherein another group be vertically set on two steel standpipes at diagonal angles, two little transverse tube other end inboards, and be oppositely arranged four steel standpipe inboards vertical and be higher than two channel-section steels of steel standpipe, two steel standpipes of each channel-section steel two side are connected and fixed by fastener with the linking steel tubes of the channel-section steel base plate back side by setting at a certain distance; Outer bar two ends of described I-shaped coupling bar respectively are equipped with can be at the roller of the channel-section steel inboard of bearing post roll-sliding, and the interior bar of I-shaped coupling bar and outer bar all have scaffold tubes; Described hanger otic placode comprises the base plate that can be connected with building by through-wall bolt and be provided with bolt hole, at the short girder steel of the shaped as frame of base plate top center fixed installation, that install and that be provided with circular hole relatively two stiffeners in short girder steel bottom surface, and install in the middle of below two stiffeners, wherein an end is fixed on the short steel pipes at place in the middle of the base plate bottom, each is connected interior bar two sides of I-shaped coupling bar by fastener with the short steel pipes of two hanger otic placodes.

Because each component and the bearing post of scaffold are connected as a single entity, scaffold aloft just is fixed, and I-shaped coupling bar then can make bearing post remain on the fixing vertical plane, and scaffold inwardly or is outwards toppled in lifting or use.The utility model can be applicable to the building of shear wall system or frame system effectively, builds easily, and is easy to operate.
