Abstract

The utility model relates to a novel automatically climbing external scaffold for a high building. The novel automatically climbing external scaffold is divided into four to eight sheets on the cross section where the building is fenced, two to four ascending scaffolds are arranged in the longitudinal position of each sheet, the height of each ascending scaffold is the height of 2.5 storeys, and a threaded rod type lifter is adopted. The utility model has the advantages of high construction efficiency, labor saving, material saving, safety, reliability, stability, no swinging, high lifting speed and wide popularization and application prospect and can be descended in advance without waiting. The utility model can be used for construction and decoration, and the lifting for each storey only needs one hour.

Description

The multistage automatic climbing external scaffolding of burst

The utility model relates to a kind of novel highrise building automatic climbing external scaffolding.

At present the hoisting scaffold of using has polytype, the attached wall hoisting scaffold, about 6 meters of every girths carry out burst with Chain block and promote, or with tower crane scaffold are carried out burst and promote, such outrigger, fracture face mostly, troublesome poeration, work efficiency is low; Integral hoisting scaffold, the many investments of the equipment that expends are big, during lifting the support body distortion bigger, guide tracked hoisting scaffold, aspect guiding, though be enhanced, operation is trouble quite, the scaffold unbalance stress.A common ground of above-mentioned various types of scaffolds: all be that one two layers are promoted with burst or whole mode to the high scaffold of four floors, but also there is an outstanding problem, scaffold has promoted up, scaffold can only satisfy the requirement of main body construction, following each floor of main body construction does not just have support body to construct, want the building is carried out finishing work, after just must waiting until that hoisting scaffold is raised to the top layer in building, down lower again, finishing work just can be carried out, because the main body construction time is longer, and the engineering that some duration is tighter, just feel awkward with the hoisting scaffold construction, in order to protect the duration, some units in charge of construction have to spend wide variety of materials and cost, set up the overall height scaffold, expend 300-500 ton steel pipe and tens thousand of fasteners, also have a large amount of safety nets, labour cost, scaffold floor.

The purpose of this utility model is the defective at above-mentioned existence, proposes the multistage automatic climbing external scaffolding of a kind of novel burst.

Technical solution of the present utility model: it encloses on the building cross section all around and is divided into four-eight, is provided with two-level Four hoisting scaffold on every lengthwise position, and the height of every grade of hoisting scaffold is the height of 2.5 floors.

Advantage of the present utility model:

(1), when construction be to fast can the falling of work efficiency in advance, needn't wait for, can save manpower.

(2), effectively overcome prior art main body with decorate the Gu that occurs when constructing simultaneously main body does not turn round and look at the contradiction of decoration.

(3), economical with materials, safe and reliable.When adopting the one-level hoisting scaffold, outrigger has only 2.5 story heights, and circulation material is about 50% of a prior art integral lifting rack, the effect that can be enhanced about more than once when adopting the two-stage hoisting frame.

(4), adopt the screw rod hoisting way, guiding, anti-drop system are arranged, steady during operation, the structure of scaffold is more stable.

(5), hoisting velocity is accelerated 1 layer/hour.

Accompanying

drawing

1,2, be example structure schematic diagram of the present utility model.

Accompanying drawing 3 is the utility model unit's facade structures schematic diagrames.Among the figure 14 is diagonal braces, and A, B are respectively the I and II hoisting scaffold.

Further describe technical solution of the present utility model below in conjunction with accompanying drawing: scaffold has force-bearing base (1), it is used to connect scaffold and body of wall, bracing piece (2) is used to reinforce scaffold, establish connecting rod (3) between the scaffold both sides, set up defences between the built-in fitting (12) of force-bearing base (1) and last layer and weigh down line (5), some cross bars (6) are set on the horizontal plane of scaffold, at scaffold outer periphery safety net (7), on the vertical direction of scaffold, set up bar (8), the both sides of connecting rod (3) upper berth scaffold floor (10) scaffold respectively are provided with directive wheel (11), feature of the present utility model is to be provided with screw elevator (4) on the corresponding position at the last layer of force-bearing base (1) on the basis of above-mentioned prior art, elevator (4) is provided with screw rod (13), and connecting built-in fitting and scaffold is that a guiding anti-fall ring (9) is arranged.Elevator (4) generally all is only to be applied in the hydraulic engineering.Use elevator (4) can significantly reduce rocking of scaffold and deviation.

The one-level hoisting scaffold, two layers of half hitch structure that set up by steel tube fastener, the bottom is fixed on the building built-in fitting by force-bearing base and obtains to support, and have other system to link to each other to make with building whole scaffold firmly, stablize, the construction worker can relievedly use (as shown in Figure 3).Hoisting way adopts the screw elevator, divides electronic and manual two kinds.Each lifting can promote one, about 1 hour consuming time.The totally-enclosed form in totally-enclosed or outside semiclosed bottom is adopted in the outside of scaffold and bottom, satisfies safety condition attractive in appearance.Secondary or multistage hoisting scaffold are the climbing scaffolds of one two floor height, and form is with the one-level hoisting scaffold.Select secondary or multistage hoisting scaffold for use according to the number of plies of building and the requirement of decoration of exterior wall engineering, also can select secondary or the multistage lifting scaffold that gets for use in the part, burst is meant that hoisting scaffold can by the face number of building separately also can be divided into 2 by every face, and several also can be joined together during last main body.As shown in Figure 1: the one-level hoisting scaffold is fixed on the N layer by force-bearing base, and elevator is fixed on N+1 layer and force-bearing base and is linked to be integral body and adds other anti-fall measures, and hoisting scaffold firmly is fixed on the building and can uses safely.After the N+2 layer main body has been built scaffold not enough the anti-fall ring of guiding on the dress N+2 layer good and sound, let fixed end and anti-drop system on the force-bearing base go, allow the weight of whole scaffold bear by elevator.Start the screw elevator, elevator is promoted to position shown in Figure 2 with outrigger, fixedly force-bearing base and anti-drop system thereof, untie the anti-fall line of elevator, let the elevator fixed end go, fix the form shown in Figure 1 of promptly reappearing again after being suspended to the N+2 layer, repeat said process, exterior wall scaffold in layer climbs up.Repeat said process in the other direction, then outrigger descends from level to level, and the principle of secondary or multistage hoisting scaffold is identical.
