Description
The invention belongs to water and build the large formwork construction scheme of high dam body of engineering dam and high large-scale concrete engineering.Especially relate to a kind of self-contained whole tearing open from the constructure scheme that promotes punching block.
At the high large-scale formwork erection of the high dam body of water conservancy construction dam, in the template construction of form removal work plane, mainly contain two kinds of formwork construction technology schemes.
The first is upright in the large, medium and small type concrete of the high dam body of dam multilayer storehouse number, outside the form removal work plane, progressively set up high-rise peripheral scaffold from the bottom up, takes fritter template splicing method and dismounting method by upright, form removal personnel, successively stands from the bottom up, form removal.Taking this job practices, mainly is that scaffold all must be taken, be torn open to each template construction, upright, form removal four procedures.In upright, form removal, take that to tear scaffold work amount open big, consumable material is many, and work efficiency is low, and is long in time limit, and working security is poor.
It two is in the craneman does the footprint.On number upright with crane under the formwork erection personnel cooperate, the form removal work plane, carry out large form installing/dismounting (Here it is, and usually said point is installed, torn open) one by one layer by layer from the bottom up in the multilayer storehouse.The major defect of this method is: 1. the peace of large form, tear open with concrete building and all need crane, thereby it is very outstanding to strive the contradiction of crane in construction mutually, influences programming widely.2. can only tear open with this crane peace that large form is one by one carried out in number beginning from a certain storehouse on upright, the form removal work plane in a plurality of storehouses in the craneman does the footprint number, and carry out the large form peace on can not be simultaneously upright on a plurality of storehouses of its footprint number, the form removal work plane, tear open (face peace, tear open).So work efficiency is low, long in time limit, programming is slow.3. the large form beyond the craneman does the footprint is pacified, is just torn open and can't carry out, so bad adaptability, is subjected to the restriction of a lot of conditions in the construction.Car is had bad luck, and formwork rigidity requires big, makes manyly with material, is fabricated into complete lifting appliance vehicle from special factory and has bad luck the scene, carries out big punching block with on-the-spot crane again and pacifies, tears open and need expend a large amount of manpowers, material resources and machine power.
In the construction of other existing templates, the sliding shuttering technology of employing in body of wall is built arranged, but all be lifting appliance to be set or to be anchored on respectively to build on the body of wall on little thickness body of wall usually with tower slip cage body.The job practices of these types is just like body of wall rising template (be used in thickness of wall body is below the 1 meter more) job practices of EP108697 report, though institute's template that adopts can be in the equal altitudes that the connects lifting that make progress on whole active length.But must provide supporting by a template, and on this piece template, lifting appliance is set, make it produce ascending motion face die plate.If thickness of wall body strengthens, the lifting appliance structure complicates, and dimensional weight all strengthens, and installation is all difficult, even this construction method will become impossible when certain thickness.And in the dam template construction, most concrete storehouse number all is thickness is very big in the horizontal direction storehouse number, and quite a lot of storehouses are number upright, form removal work plane opposite does not all have template can provide the supporting lifting appliance.Therefore, this class template construction method can't be applied in the high dam concrete template construction of dam.
The disclosed jumping formwork of Deutsches Reichs-Patent (DE2760022) also belongs to the body of wall jumping formwork.This template is by upright, the form removal of finishing each template with the tower winding frame of slip cage body and lifting appliance and lifting work.During climbing shuttering, pylon and slip cage body adopt the separate type anchor device, directly fix with the body of wall of pouring, and when pylon rose, slip cage body was fixed.Pylon was fixed when the cage body rose, and stood, when tearing climbing shuttering open, and template is unclamped the back from crab-bolt up climbs template by the lifting appliance on the pylon.This hoisting frame and lifting appliance complex structure weight with the cage body is big, installs, the dismounting trouble, can not arbitrarily make things convenient for immediately as special tool, constructs on several bodies of wall storehouse number simultaneously.Therefore, tower winding frame and lifting appliance with the cage body all must be installed on each body of wall storehouse number.In construction, this climbing device requires to make many inevitably.And it highly also must be higher than the required hoisting depth of template.Therefore, the size of shelf and weight are all bigger, and this is for large tracts of land, and the hydraulic engineering construction of big height is impossible basically.
Purpose of the present invention, be in order to shorten water conservancy project dam, high dam body or high large-scale concrete engineering template construction duration, speed up the work, simplifying working procedure saves material for the template construction of high large-scale concrete engineering provides a kind of, the man power and material, easy to operate construction formwork and hoisting frame thereof.Large, medium and small delaminated cabins all on working face is number upright, the form removal work plane diminishes piece splicing method and dismounting method is that large form promotes peace, tears method open in the hope of solving; The peace of solution large form in construction, tear the contradiction of striving crane with concreting open; Become the large form point of crane on work plane and be installed as the face installation.
The present invention finishes like this, reserve longitudinal joint between the self-contained good big punching block on, the form removal work plane upright in concrete storehouse number, longitudinal joint simple and easy hoisting frame is set on the right former concreting, the lower cantalever that hoisting frame is provided with back shelves mould cross bar is clipped between the two big punching blocks.When promoting upright, form removal, at first use temporary rod grappling shelf, again the hand cucurbit on the hoisting frame upper cantilever suspension ring is tangled an end of steel cable, the other end of steel cable hitches the suspension hook of big punching block bottom, what does not spur the hand cucurbit on the hoisting frame of both sides the first day of the lunar month synchronously, makes that the big punching block that is provided with scaffold is up sliding to be risen.During template sliding lifting, template is limited between the front and back crosspiece mould cross bar set on the upper and lower cantilever of hoisting frame and slides.
The big punching block in hoisting frame both sides is mentioned required formwork erection height, the upper and lower cantilever of shelf all is clipped between the two big punching blocks, to reduce the height of hoisting frame, reduce rack design size and weight, be convenient to can remove easily at any time, everywhere and move on to other local upright form removal as special tool.
In the present invention, self-contained big punching block lower floor enclose the purlin crack and do not have the steel form face locating, being convenient to big punching block promotes when in place, it (is that lower floor builds the storehouse when number building that its lower floor encloses purlin crack and pouring concrete upper sleeve bolt hole (28), the grappling draw rod positions of template, take off the sleeve bolt on the pull bar during form removal, promptly staying bolt hole on the concreting.) contraposition wears tight sleeve bolt with the formboard fastening effect, and can weld one deck pull bar less.
