Description

Lifting scaffold with auxiliary beam for high building

The utility model relates to the suspended scaffold by the house supporting that the building operations personnel use, and specifically is meant a kind of highrise building attaching beam formula lifting false work.

At present, the general external scaffolding of using in the high-building construction, mainly contain console mode fastener steel tube frame, segmentation steel pipe frame, door frame, hanger---the hanging basket system etc. of encorbelmenting, although it is various informative, the material consumption amount is big, holding time long, consume the worker, scaffolder's high-altitude application environment is abominable but all exist to some extent, problems such as contingency accident easily take place, and make the outrigger engineering become headachy one difficulty in the high-building construction.A kind of wall-attached (shear wall) liftable out-mould scaffold pin of lifting had appearred carrying out according to the principle of climbing of creeping formwork in recent years in China's some areas high-building construction, it is compared with traditional console mode scaffold, save the frame material more than 90%, save work day more than 50%, neither take tower crane, reduced scaffolder's labour intensity again, improved operating environment, safe and reliable, solved the shelf pass difficult problem that the highrise building shear wall is partly constructed breakthroughly.But, in highrise building, account for the frame part and the balcony part of significant proportion, promptly be vertically to be discontinuous plate and girder construction part, in construction, still adopt traditional external scaffolding, spacious sick a lot of.

The purpose of this utility model is on the basis of existing wall-attached (shear wall) liftable external scaffolding, provides a kind of for vertically being the highrise building attaching beam formula lifting false work that discontinuous girder construction is partly constructed.

Solution of the present utility model is, still as existing wall-attached (shear wall) liftable external scaffolding, have two upright side direction saddles, the saddle transverse brace that between two side direction saddles, has several groups of differing heights that two ends are connected mutually with two side direction saddles respectively, go up most one group of saddle transverse brace below, have two upright side direction stocks, the upright loop bar of these two side direction stocks sliding sleeve respectively is combined in outside the upright guide rod of two side direction saddles, have between two side direction stocks two ends respectively with two side direction stocks be connected mutually on, following two groups of stock transverse braces, on two side direction saddles and two side direction stocks, be fixed with respectively and be used for the shelf lifting, following two saddle suspension ring and last, following two stock suspension ring have the front rail handrail that is connected mutually with it respectively in the outside of lateral guide top of the trellis and bottom.Feature part of the present utility model is, both sides also have respectively the upright auxiliary rod that is connected mutually with the side direction saddle, has the transverse brace that two ends are connected mutually with auxiliary rod respectively between the auxiliary rod; On two side direction saddles below two side direction stocks, all have node and saddle lower node on the saddle successively, have node on stock lower node and the stock respectively, on above-mentioned node, all have and the latch connecting hole in two side direction stock bottoms and top; Attaching beam duplex node with eight same structures, the structure of each attaching beam duplex node is, has a π type duplex node accessory, the mainboard central authorities of duplex node accessory have the strip through hole, long bolt and nut component is housed in the hole, all have upper and lower two pin holes on two side plates of duplex node accessory, a latch respectively is housed in the hole, an end of latch is fixed with cottor pin; Have two firmwares that are connected mutually and form by standard scaffold tubes and firmware node, have on the firmware node and the latch connecting hole.

The utility model with said structure is when concrete the use, should hang in the high-rise building side that the side bar structure is arranged by its attaching beam duplex node, its specifically the method for hanging be, both sides all have preformed hole on the side bar in four adjacent from the bottom up floor rooms, pass preformed hole with the bolt and nut component on the attaching beam duplex node, respectively eight attaching beam duplex nodes are close to and are fixed on the side bar side (if the side bar of the 4th floor is not constructed from the bottom up, then treat construction good after fixing attaching beam duplex node again), again node on the saddle lower node of two side direction saddles and the saddle is locked with the latch of first floor and second layer building attaching beam duplex node from the bottom up respectively with the latch connecting hole mutually by it and connected, node on the stock lower node of two side direction stocks and the stock is locked company with the latch of the attaching beam duplex node of the second layer and three-storey building from the bottom up by it respectively mutually with the latch connecting hole.By above-mentioned connection, just can make whole scaffold be fixed on side of buildings firmly.The constructor stands on saddle transverse brace and the stock transverse brace, just can carry out constructing operation.When need promote the first floor height with side direction stock and stock transverse brace, respectively increase for two lateral guide top of the trellis and connect a firmware, to prevent the unstability of long vertical rod in the saddle.Available fastener is connected between the standard scaffold tubes of firmware and the saddle, and locking mutually with the latch connecting hole and the latch of the duplex node in the 4th floor room from the bottom up on the firmware node connects.Then jack is tensioned between uppermost saddle suspension ring and the stock suspension ring, again with node on two stock lower nodes and two stocks respectively with the latch of attached beam duplex node be separated, the pulling jack, just side direction stock and stock transverse brace upwards can be promoted, after promoting the first floor height, its node is retightened on the attaching beam duplex node of floor of living in, remove jack, just finish lifting, thereby can carry out the constructing operation of desired area.When needs promote the first floor height with side direction saddle and saddle transverse brace etc., jack is tensioned between nethermost saddle suspension ring and the stock suspension ring, and all the other operating procedures are identical with the operating procedure that above-mentioned side direction stock and stock transverse brace rise basically.This scaffold is by above-mentioned twice lifting, returns to the state before promoting again, and the climbed height of first floor of whole scaffold carries out so repeatedly, and scaffold just can constantly raise.Letdown procedure is just in time opposite with climb procedure.

The utility model is except that possessing all advantages that aforementioned wall-attached (shear wall) liftable external scaffolding had, also has following advantage: 1. the crane scope of application is partly constructed from single highrise building shear wall and develop into the construction of the highrise building that vertically is discontinuous girder construction part (as side bar), widened the scope that crane is used widely; 2. attaching beam duplex joint structure is light and handy, reasonable in design, connects and simple and direct, the rapid convenience of dismantling operation, and is safe and reliable, still can adapt under building preformed hole situation devious and normal the use; 3. the employing of firmware makes the scaffold rising and descends safer reliable; 4. all members can be gathered materials on the spot, and process easily and promote the use.
