Description
Technical field
The utility model relates to building field, particularly a kind of assembled lifting protecting screen.
Background technology
At present, in highrise building, attachment type raise scaffold replaces the fixed scaffold of traditional bottom support gradually, lifting false work major advantage compared with traditional pin hand cradle has: 1. economic performance is good: no matter how high building have, use lifting false work only to need the circulation material of four-five layers, save material lease expenses, support body is once put up, tower crane is no longer needed to coordinate, circulation material in use loss is little, loses few, and saves tower crane working day cost use.2. security performance is good: because lifting false work starts to set up at building first typical floor place, avoid support body continuously to take in the air at height and tear open, decrease the dangerous works such as handling circulation material falls, after support body lifting puts in place, support body is in full closeding state, avoid falling of any constructional materials and personnel, thoroughly realize safety work.3. easy to use, efficiency is high: after lifting false work is set up, during the normal lift work of support body, lifting one deck only needs 1 ~ 2 hour, scaffolder can complete lift work when can take advantage of other teams and groups' midday rest, avoid the unsafe factor that each work post cross-operation brings, easily meet the requirement of 3-4 days main body construction one decks, realize convenience and the high efficiency of construction.
But because current lifting false work does not have national standard, the support body of various model has bigger difference, the power more than 98% of the lifting false work now commercially used is electric chain hoist, the weight of an electric block is about 100kg, after being elevated a node layer, need electric block to have enough to meet the need to move or send behind, because electric block is heavier, workman is very painstaking in handling process, some building site is even equipped with 1/3 for electric block of economizing on the use of funds only is equipped with half, virtually add the labour intensity of workman, add and pluck, hang the unsafe factor of electric block, cucurbit is repeatedly being seted out and is easily occurring turning over chain in moving process, button chain, carry the phenomenons such as foreign material secretly, increase the risk of chain rupture, hazards in keeping the safety in production are increased.
Fall to effectively prevent support body, in scaffold, anti-drop system must be installed, existing anti-drop system comprises anti-drop device, anti-fall wire rope and pendant block etc., when elevator chain or suspension hook lost efficacy, anti-drop device can hold anti-fall wire rope tightly automatically, produce braking, thus prevent support body from falling, but existing attaching scaffold is due to its structural problem, skidding effect is undesirable, there is potential safety hazard, and complex structure, install and use trouble, cost is high, and at high level, fire safety problem particularly in Super High construction also annoyings building trade always, therefore, its improvement and bring new ideas is imperative.
