Abstract
The invention relates to a multi-story and high-rise mixed structure building system construction technology, and aims to provide a self-supporting combined steel template construction method. The method comprises the following steps of: integrally and inversely assembling a self-supporting combined steel template on the ground surface or a platform, and lifting the inverse self-supporting combined steel template to a specified position through a tensioning device; connecting the inverse self-supporting combined steel template with a middle supporting seat though a horizontal connecting rod, and integrally overturning the inverse self-supporting combined steel template into place around a middle supporting seat horizontal connecting rod under the action of self-gravity; realizing connection through a side supporting seat horizontal connecting rod; and during construction of a self-supporting combined steel template of a next independent unit, circularly performing the construction steps. Compared with a construction method for erecting full framing scaffolding, the method has the advantages that the template construction cost is lowered greatly, the construction speed is increased greatly, and the site construction environment is improved remarkably.
Description
Technical field
The invention belongs to many Tall Building Hybrid Structure building system construction field, be specifically related to a kind of self-bearing type combined steel board construction method.
Background technology
In recent years, many Tall Building Hybrid Structure buildings are increasing, and the feature of this structural system is: (1) post generally adopts steel column, steel core concrete column or combined steel and concrete column; (2) beam generally adopts H section steel beam; (3) floor adopts cast-in-place concrete floor or composite floor; (4) flooring arranges primary-secondary beam, and floor span is less.
The template of China's cast-in-place concrete floor, generally adopts wooden form or combined steel formwork at present; Wherein wooden form because of material turnover low, the shortcoming such as speed of application is slow, and timber waste is serious, and being subject to certain restrictions in the use.When floor project is constructed, the general prior full hall scaffold of setting up, lays template, steel mesh reinforcement on scaffold, then disturbing concrete, when concrete reaches some strength, removes scaffold and template.This construction method scope of application is more extensive, but need to set up full hall scaffold, can not multilayer construct simultaneously, and construction speed is slow, takies a large amount of circulation materials, and construction cost is high.
Another construction method is exactly self-supported formwork construction, and self-supported formwork construction is that the reinforcing bar in floor is become to three-dimensional steel bar girder in factory process, and the three-dimensional sheet material that three-dimensional steel bar girder and galvanized steel plain sheet are welded into one; During construction, be directly installed on girder steel, re-lay after additional bar, can bear construction stage concrete gravity and construction live load, without setting up scaffold support; But this construction method is when concrete reaches some strength, template will be difficult to remove, and generally galvanized steel plain sheet need be used as permanent shuttering; From economic angle, construction cost is too high; From use angle, galvanized steel plain sheet, as ceiling, is unfavorable for the decoration of floor ceiling, As time goes on dimmed, corrosion gradually of galvanized steel plain sheet ceiling simultaneously, and impact is used.

(2), on the bottom flange of the H of construction floor both sides section steel beam, a middle bearing and two limit bearings are all installed;
(3) the H shaped-steel-beam upper wing-edge in upper floor both sides hangs respectively suspension hook;
(4) between the panel point of inverted self-bearing type combined steel formwork and suspension hook, tensioning equipment is set, by tightening up tensioning equipment, the correspondence position by self-bearing type combined steel formwork Integral lifting to the H section steel beam of construction floor;
(5) regulate horizontal brace rod and the vertical bar of two middle bearings, the quick connection in realization between the horizontal brace rod of bearing and self-bearing type combined steel formwork;
(6) slowly loosen tensioning equipment, make inverted self-bearing type combined steel formwork horizontal brace rod unitary rotation around middle bearing under Gravitative Loads, turn over turnback and complete in place;
(7) regulate respectively horizontal brace rod and the vertical bar of each limit bearing, the quick connection between the horizontal brace rod of realizing limit bearing and self-bearing type combined steel formwork;
(8) remove suspension hook, tensioning equipment and middle bearing;
(9) while carrying out the self-bearing type combined steel formwork construction of next separate unit, the above construction sequence of cycling.
In the present invention, the construction that the template construction of each floor area comprises a plurality of separate unit self-bearing type combined steel formworks, in the region that completes the construction of self-bearing type combined steel formwork, place reinforcing bar, then fluid concrete, after concrete strength reaches predetermined strength, can remove self-bearing type combined steel formwork, carry out recycling of next region self-bearing type combined steel formwork construction.
In the present invention, in step (1) afterwards, can also, by adjusting self-bearing type combined steel formwork physical dimension, realize leveling or arch camber requirement.
In the present invention, the quick connection between the horizontal brace rod of described middle bearing and limit bearing and self-bearing type combined steel formwork is to be all connected on truss.
The invention has the beneficial effects as follows:
(1) economic benefit: the present invention has cancelled the use of steel pipe scaffold, adopt whole inversion assembling self-bearing type combined steel formwork on ground or platform, form inverted self-bearing type combined steel formwork, inverted self-bearing type combined steel formwork Integral lifting and integrated overturn construction in place, construction method cost of the present invention with set up full hall scaffold, traditional self-supported formwork construction method is compared, template construction cost declines to a great extent;
(2) duration effect: the present invention is owing to need not setting up scaffold, adopt whole inversion assembling self-bearing type combined steel formwork on ground or platform, form inverted self-bearing type combined steel formwork, inverted self-bearing type combined steel formwork Integral lifting and integrated overturn construction in place, the impact that is not subject to lower-layer concrete intensity and builds; Operating efficiency is high, and template construction speed significantly improves;
(3) saving and environmental protection: the present invention is in implementation process, and template accessory all adopts standard component, can recycle by subdivision, and form of structure adopts self-bearing type combined steel formwork, without extra temporary supporting; Save material, reduce construction noise, Contraction in Site environment obviously improves;
(4) application value: adopt the present invention to solve and set up the difficult problem that finished product increases, duration increase brings that full hall scaffold causes, and quick construction, safe and reliable, increase work efficiency, reduce engineering cost, have highly application value.
