Description
Technical field
The utility model relates to the electric jacking flat bridge that uses in a kind of chimney wall construction.
Background technology
Tradition chimney wall construction sliding formwork, the electric mould-lifting technologies of adopting, vertical transport adopt electric winch to be located at the cage at chimney center or directly to adopt construction elevator by promoting with the gug frame more.Beginning each investor from 1999 all requires chimney construction to adopt electric mould-lifting or over-form construction technology.
Electric mould-lifting process using electric mould-lifting operating platform mainly is made up of hoisting frame, adjustable shelf, transmission mechanism, guide rail and lifting platform.Hoisting frame is constructor's a last lower channel, is the stress point that supports sliding platform; Adjustable shelf slides in handling frame, is the support of hoisting frame motion; Transmission mechanism is made up of motor, helical screw, hold-down nut etc., acts on respectively on hoisting frame and the adjustable shelf, by the Synchronization Control of motor with just changeing counter-rotating and finishing the alternating movement of hoisting frame and adjustable shelf; Guide rail is to make whole electric hoist template system attached to the main member on the barrel.It adopts the template expansion loop on high-strength bolt and opposite to be connected, and clamps the concrete barrel tightly.One group of guide rail three saves up and down totally, and the high 1.5m of every joint guide rail is joggle, then has two adjustable screws to be used for regulating guide rail vertical slope and guide rail broadwise verticality at the back at nearly concrete face place between the last lower guideway.Have three square holes on the side plate of guide rail, can insert rectangular pin, this rectangular pin is used for supporting hoisting frame and adjustable shelf.Lifting platform is constructor's a safety work face, two parts about every layer of platform is divided into, and the end is shelved on the hoisting frame, and the centre is connected with pulley, so that flexible.The first floor platform is used for work such as assembling reinforcement, pouring concrete, mounting guide rail, horizontal construction joint processing, and second layer platform is to install and stripping usefulness, and the 3rd layer of platform is to carry out guide rail to remove, operate work such as climbing of hoisting frame.Template adopts unit large tracts of land assembly unit, props up and tears open conveniently; Real outer light in the barrel concrete structure, presentation quality is better than sliding formwork; Every liter of one-off pattern, the High Altitude Platform center just aligns once, and the template radius is measured timely correction with steel ruler, thereby reduces the chimney centre deviation, and the electric mould-lifting operational security is good, and labor strength is low.But electric mould-lifting operating platform mounting or dismounting difficulty is big; Promoted synchronization constrain; The barrel at guide rail place easily produces groove mark, template and easily produces difference of height; The lifting time is restricted by the barrel concrete strength; Hoist engine traction material loading elevator is attached on the Flexible slideway; Disposable consumable material is many.
Over-form construction process using suspension type tripod turns over modular system, by brace in platform, the tripod, tripod outer brace, tripod waling stripe, hang indigo plant, hoop purlin, support rod and form.Every layer of tripod unifies, and becomes a hoop rigid structures.As operating platform, carry out template and tripod installation, reinforcing bar binding and the concrete pouring construction etc. of its last layer with this tripod system that fixes.Tripod is provided with three layers, after the bottom concrete strength reaches, removes orlop tripod and template and transports on the tripod platform of upper strata.Turnover is successively used, up to finishing whole barrel construction.Its advantage is: construction quality is good, owing to adopt the accent arc template of broad, impression is effective, and speed of application is fast, and one-time investment is little.But tripod and template promote by artificial fully, and labor strength is big.
The utility model content
The purpose of this utility model is that a kind of concrete chimney that is applicable to outlet diameter 〉=6.0m will be provided, and one-time investment is few, and operating cost is low, and constructing operation is simple and convenient, and speed of application is fast; Safety is guaranteed, system easy to control the quality, and impression is effective, the electric jacking flat bridge that can apply in towering reducing engineering structures.
Technical solution of the present utility model is:
This electric jacking flat bridge, comprise guide rail, hoisting frame, hoisting frame is mounted on the guide rail, be provided with support roller in the hoisting frame bottom faces to barrel one side, on hoisting frame, be provided with transmission mechanism and adjustable shelf, can realize alternately promoting of hoisting frame and adjustable shelf by transmission mechanism, its special character is: described guide rail has three, wherein one is interior guide rail, two is outer guide in addition, corresponding hoisting frame is three Pin and is respectively interior hoisting frame and outer hoisting frame, the hoisting frame bottom inside is provided with anti-hook wheel outside, described anti-hook wheel is positioned at guide rail, at interior hoisting frame top lifting platform is installed, is hinged with the center large platform and supports by elastic jackstay towards chimney center one end at lifting platform, the hoisting frame top is provided with vertical rod outside, outer hoisting frame hangs and draws the center large platform by being connected drag-line in the vertical rod, vertical rod and outside be connected with pull bar between the hoisting frame.
Above-mentioned electric jacking flat bridge, described elastic jackstay are to be made of inside and outside sleeve pipe and the butterfly spring that is arranged in the outer tube.
Above-mentioned electric jacking flat bridge, the hoisting frame bottom is provided with counter-balanced carriage outside.
Above-mentioned electric jacking flat bridge, every guide rail is five joints.
The utility model has the advantages that: can solve the horizontal transportation problem in high-altitude to horizontal transport channel with the tripod makeup ring, make the template piece regular, smooth bright and clean slyness, do not have reverse, groove mark, drawing crack phenomenon, system easy to control the quality, impression quality obviously improves, construction safety; Constructing operation is simple and convenient, and speed of application is fast; Concrete strength is not had specific (special) requirements, and disposable less input, saves labour cost and equipment leasing expense, and this method is applicable to the concrete chimney of outlet diameter 〉=6.0m, can be applicable in towering reducing engineering structures.
