Description

Large space concrete structure scaffold
Technical field
The utility model relates to E04G scaffold, formwork; Template construction apparatus or other building servicing unit technical field relate to scaffold building construction technology, built-in fitting installation Technology, reinforcing bar, concrete construction technology, especially large space concrete structure scaffold.
Background technology
At building field, important construction equipment during scaffold, bearing capacity is big, mounting or dismounting are convenient, set up advantages such as flexible, economic and practical and fastener type steel pipe scaffold has, its double-pole scaffold system by wide popularization and application in building engineering construction.Common buildings is in work progress; The external scaffolding wall-connecting piece is connected with agent structure and is easier to; Connect the wall point and in large span, ultra floor height structure, lack between external scaffolding and the agent structure; Conventional construction technology is difficult to solve this type of problem, and this just needs a kind of new wall-connecting piece technical application, guarantees that external scaffolding can satisfy safety and construction demand.
In the known technology, along with the development of economic construction and Building technology, large bay, large span, big scale of construction building increase year by year.Because the vertical spacing of the colum network size of this type building, building floor height, horizontal member is bigger; The layout of building operations scaffold connecting spare is restricted; Can not satisfy " building operations fastener type steel pipe scaffold technical specification of security " (JGJ130) requirement of technical standards such as (hereinafter to be referred as " standards "), bring new problem for scaffold safety.
The definition of large space: when the vertical spacing of colum network size, building floor height and horizontal member was striden greater than 3 steps or 3 of scaffold upright rod, when the layout of wall-connecting piece can not satisfy " standard " regulation, promptly think colum network size, building floor height and horizontal member; It is bigger to be called for short colum network size, building floor height, vertical spacing, and the design of scaffold and construction should be taked corresponding technical measures, and scaffold is dull and stereotyped as the structure form of vertical placement; Its thickness is much smaller than longitudinal length and vertical height, and lateral rigidity is very little, can only rely on wall-connecting piece and reliable connection of building keep monolithic stability; The support body width is more little, and the lateral rigidity of scaffold is more little, and the lateral deformation under the wind action is just big more; When scaffold is in cantilever position; The support body width is more obvious to the stable influence of scaffold, and depth-width ratio is big more, and stability is poor more; Template at concrete post supports, reinforcing bar group pricks, the concrete construction stage; Because can not being installed, wall-connecting piece or building structure can't bear the horizontal thrust that scaffold produces because of wind load; Scaffold is as cantilever member, jib-length more greatly, high highly more, stability is poor more.When the pillar constuction joint carries out template, reinforcing bar and concrete construction with the upper part, the wall-connecting piece on scaffold top, bottom will bear the wind load that comprises that the scaffold bracketed part transmits, and the bearing capacity of wall-connecting piece is had higher requirement.The bracket scaffold that the support body height is bigger even depth-width ratio is reasonable, under wind action, when bearing capacity of foundation soil is not enough, will have a negative impact to the monolithic stability of support body.Under above-mentioned three kinds of working conditions,, be totally unfavorable to the stable of scaffold if large tracts of land is hanged up the dense mesh type safety net.Wall-connecting piece is provided with spacing and position effects in the lateral plane of scaffold; Wall-connecting piece is as intermediate support; Can stop the whole lateral displacement of scaffold, prevent that scaffold from inwardly or outwards toppling, play a role to scaffold is stable in the spacing of wall-connecting piece setting and position.Under wind action, scaffold will produce the integrally bending distortion, make vertical rod become bending component.The vertical spacing of wall-connecting piece is big more, and this distortion is also just bigger, and the condition of work of vertical rod is poor more, and bearing capacity is low more.The distance of wall-connecting piece and scaffold host node also is the key factor that influences vertical rod stability.Because acting on the wind load of scaffold is through wall-connecting piece; Pass to engineering structures with the form of concentrated force; This concentrated force obviously is disadvantageous to the stable of scaffold upright rod, and horizontal concentrated force is bigger, big more apart from the distance of scaffold host node, and influence is just serious more.The technical measures that improve scaffold monolithic stability and vertical rod bearing capacity comprise: the scaffold upright rod of frame structure engineering, should arrange according to post net layout.Promptly arrange row's vertical rod at each pillar position, middle principle according to≤effective span on average is provided with vertical rod, and wall-connecting piece is arranged on the pillar, creates conditions for satisfying " standard " regulation that relevant wall-connecting piece is provided with position, spacing.On the pillar of frame construction and horizontal member, wall-connecting piece is set.Wall-connecting piece is provided with spacing: vertical direction was not more than for 2 steps, and horizontal direction is not more than 3 and strides.Should adopt the rigidity wall-connecting piece, and carry out bearing capacity calculation by the actual horizontal loading of bearing of wall-connecting piece under the most unfavorable processing condition condition.Wall-connecting piece on floor structure or the horizontal member should be arranged on the outside of beam column; So that regulate the wall-connecting piece position; Make it to satisfy the requirement of " standard ", can suitably regulate the scaffold step pitch in case of necessity, make that the position that is provided with of wall-connecting piece overlaps or as close as possible host node with the scaffold host node on the horizontal member with the distance of host node; To reduce horizontal force, improve the stress performance of vertical rod to the stressed adverse effect of vertical rod.In template, reinforcing bar and the concrete construction stage of frame construction pillar, scaffold should fuse with the floor structure form bracing system, to guarantee the stable of support body.Before removing the scaffold wall-connecting piece should be installed in time, horizontal and horizontal diagonal brace is set at floor structure concreting completion, form bracing system, with reliable binding that guarantees scaffold and building and the lateral deformation that reduces support body.Laterally diagonal brace be provided with the position should with the wall-connecting piece position consistency, the spacing of vertical transverse diagonal brace is suitable ≯ 3 stride, the spacing of horizontal diagonal brace is suitable ≯ 2 step framves.Can take suitably to strengthen the method for scaffold transverse width in case of necessity simultaneously, improve the lateral stiffness of support body.The horizontal diagonal brace vertical transverse of the horizontal diagonal brace vertical transverse of vertical transverse diagonal brace vertical rod wall-connecting piece horizontal cross diagonal brace floor beam slab-type apartment building face beam slab flooring beam slab wall-connecting piece post diagonal brace vertical transverse diagonal brace wall-connecting piece flooring beam slab wall-connecting piece horizontal cross-brace post wall-connecting piece horizontal diagonal brace vertical transverse diagonal brace cross-brace net spacing >=4 are striden floor height ≯ 3 step post net spacing >=4 and are striden floor height >=4 steps.
