Abstract
The present invention relates to a high-level arc-line slide-moving installation method of steel structure truss. In the concrete, on the concentric curved steel beams respectivley positioned on two ends of the truss to be installed the sipways are respectively set, each of two ends of the truss is equipped with slipper respectively. A hydraulic traction equipment can be used for pulling the slipper and making it be moved along the slipway from far end place of two slipways. After the first main truss is hoisted to high level and assembled into one whole body, the slipper can be forwards slide-moved by one truss width, then the second main truss can be assembled and connected with member between trusses, and can be slide-moved by one truss width, so that the above-mentioned steps can be circulated until several truss units are assembled into a whole body unit, then the whole body unit can be slide-moved into the designed plane position.
Description
Technical field
The invention belongs to the steel building technical field of construction, be specifically related to a kind of steel structure truss high-altitude camber line slide installation method.
Background technology
Flourish along with China's economic construction, large-scale public building such as airport, conference and exhibition center, sports palace, assembly hall theater etc. have obtained using widely.These buildings are generally the long-span space steel work, and form of structure has rack, space truss etc.Composite factors such as stressed and construction features according to truss, field condition, on-the-spot construction technology condition and device resource are installed at the scene of steel work, generally can be divided into high altitude bulk method, itemize or piecemeal installation method, high-altitude sliding method, whole hanging method, whole lift method and integral jacking method.The quality of on-the-spot mounting method has very big influence to construction period, comprehensive cost.Every kind of mounting method is all by oneself pluses and minuses.The high altitude bulk method can be installed with general lifting appliance and fastener type steel pipe scaffold, but the scaffold consumption is big, work high above the ground is many, long in time limit, to account in the building field land used many, and technical acquiring a certain degree of difficulty.Itemize or piecemeal are installed method and generally can not be used separately, be used with other mounting methods such as high altitude bulk method, high-altitude sliding method etc.Whole hanging method is higher to the crane performance requirement, and construction condition requires relatively stricter, for example, assembly unit in place place, crane travel etc. be arranged.Whole lift method one is that the requirement truss must be by high-altitude mounting position assembly unit in place on ground, and promptly high-altitude mounting position and installation on ground position must be on same plane of projection, the 2nd, and the rod member that requirement periphery and pillar are collided must be reserved, so limitation is bigger.Integral jacking method construction embodiment at home is less, and difficulty of construction is big, cost is high and the jack-up construction technology is relevant with structure itself, uses less.The high-altitude sliding method by being arranged on rack end or middle part local assembly unit frame (or utilizing the built construction thing) as the installation at high altitude platform and be located at both sides or middle same long slideway, be combined into strip or block unit on ground, winch to and be assembled into sliding element on the platform for lining, design attitude is arrived in the truss slippage with pulling equipment.But it is linear slippage that the sliding construction technology only limits to the slippage route at truss two ends.
Along with expanding economy, novel form of structure is more and more, and for example the girder steel at truss two ends is a camber line shape etc., and span is increasing, and this just needs more reasonable, more economical mount scheme.
Summary of the invention
The objective of the invention is to propose a kind of slippage route the steel structure truss high-altitude slide installation method that is arc.
The steel structure truss high-altitude slide installation method that the present invention proposes is provided with slideway A-A ' and GG ' respectively on the concentric circular arc girder steel in the both sides of truss to be installed, the axis of slideway A-A ' and GG ' also is two concentric circular arc lines; The two ends of main couple to be installed are arranged on the custom-designed piston shoes 15, and piston shoes 15 move at slideway upper edge slideway; The outside at the end of two slideways A ', G ' is provided with two hydraulic traction devices 10 respectively by reaction frame platform 9, two draw-gears 10 are connected with piston shoes 15 by steel strand 7 respectively, two draw-gears, 10 synchronous workings, thus by steel strand 7 pulling two piston shoes 15 with main couple along the slideway synchronization-sliding; If the spacing of adjacent two main couples is the B degree; Concrete installation steps are as follows:
The one Pin main couple is after the assembling of ground, winch to the installation at high altitude support with loop wheel machine, in end regions, be assembled into integral body, two hydraulic traction devices 10 by two slideway far-ends spur synchronously, along both sides slideway pulling B degree, carry out the assembling of the 2nd Pin main couple then, and connect the member 14 between truss, slippage B degree again; Carry out the installation of member between the assembling of the 3rd Pin main couple and truss thereafter; So circulation becomes integral unit until many truss structures unit splicing, and the whole unit slippage is to the design plane position then.Whole slippage installation process comprises accumulation slippage and two stages of integral slipping:
The accumulation slippage stage: Pin main couple lifting, temporary fixed → single truss structure along the circumferential direction between slippage B degree → the 2nd Pin main couple lifting → the first truss structure lifting component → two truss structures together along the circumferential direction lifting component between slippage B degree → the 3rd Pin main couple lifting → the second truss structure → ... → the first to the 5th truss structure is lifting component between → the five truss structure of slippage B degree → the 6th Pin main couple lifting along the circumferential direction together.When the truss accumulation slippage finishes, form after the integral slipping unit beginning integral slipping.The same accumulation slippage of integral slipping hydraulic haulage mode.Draw the integral slipping unit continuously by the hydraulic haulage device, until design attitude.
Both sides slideway length difference, but they lay respectively on two sections isocentric circular arc, the synchronism of the angular velocity by control both sides slide plate slides converts the synchronism of control slide plate linear velocity to, and linear velocity can be regulated by oil pump flow.Whole Hydraulic Synchronizing draw-gear can be by computer control.
When towing point quit work, sliding element produced brake force by the frictional force between slide plate and the slideway.According to momentum identity: F * t=m * v.Wherein, F=N * μ brings identity → N * μ * t=m * v into.Slide plate equals superstructure deadweight m to track normal pressure N, and coefficientoffriction, hauling speed v all equate, so the braking time of each slide plate equates.Be sliding element in braking procedure, each fulcrum keeps synchronously, no additional internal force.Can guarantee stability of structure.
The present invention can solve crane machinery can't lift the difficulty that puts in place, and during truss construction, civil engineering can cross-operation; The assembling support expense is saved than high altitude bulk method, and it is few to take building periphery place, and having on one side, the construction plant gets final product.By the computer Synchronization Control, make steady, safe, the quick slippage of member to assigned address.The construction of employing the method can obtain obvious economic benefit,
