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 characteristics of this structural system are: (1) post generally adopts steel column, steel core concrete column or combined steel and concrete column; (2) beam generally adopts the H section steel beam; (3) floor adopts cast-in-place concrete floor or composite floor; (4) flooring is provided with the primary and 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; Shortcomings such as wherein wooden form is low because of material turnover, and speed of application is slow, and the timber waste is serious, and receive certain restriction in the use.When the floor engineering construction, the general prior full hall scaffold of setting up is laid template, steel mesh reinforcement on the scaffold, and disturbing concrete again when treating that concrete reaches certain intensity, is removed scaffold and template.This job practices scope of application is more extensive, but need 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.
A kind of in addition job practices is exactly self-supported formwork construction, and the self-supported formwork construction is that the reinforcing bar in the floor is become 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; Be directly installed on during construction on the girder steel, re-lay additional bar after, can bear construction stage concrete deadweight and construction live load, need not to set up scaffold and support; But when this job practices treats that concrete reaches certain intensity, template will be difficult to remove, and generally need galvanized steel plain sheet is used as permanent shuttering; See that from economic angle construction cost is too high; See that from use angle galvanized steel plain sheet is unfavorable for the decoration of floor ceiling as ceiling, As time goes on deepening gradually, corrosion of galvanized steel plain sheet ceiling simultaneously, influence is used.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency that prior art exists, and a kind of self-bearing type combined steel board construction method of effective reduction construction cost is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopted is:
A kind of self-bearing type combined steel board construction method is provided, may further comprise the steps:
(1) panel steel form is down placed on ground or the platform, the placed on it and fixed connection with space truss then forms the inverted self-bearing type combined steel formwork of an integral body separate unit;
(2) on the bottom flange of the H section steel beam of construction floor both sides, a middle bearing and two limit bearings are installed all;
(3) hang suspension hook respectively in the H section steel beam bottom flange of last floor both sides;
(4) between the panel point of inverted self-bearing type combined steel formwork and suspension hook, tensioning equipment is set,, self-bearing type combined steel slab integral is risen to the correspondence position of the H section steel beam of construction floor through tightening up tensioning equipment;
(5) regulate the horizontal brace rod and vertical bar of two middle bearings, the quick connection in the realization between the horizontal brace rod of bearing and the 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 the deadweight effect, turn over turnback and accomplish in place;
(7) the quick connection between the horizontal brace rod of regulating each limit bearing respectively and vertical bar, the horizontal brace rod of realizing the limit bearing and self-bearing type combined steel formwork;
(8) remove suspension hook, tensioning equipment and middle bearing;
When (9) carrying out the self-bearing type combined steel formwork construction of next separate unit, the above construction sequence of cycling.
Among the present invention; The template construction of each floor area comprises the construction of a plurality of separate unit self-bearing type combined steel formworks; Place reinforcing bar in the zone of accomplishing self-bearing type combined steel formwork construction, fluid concrete then, treat that concrete strength reaches predetermined strength after; Can remove the self-bearing type combined steel formwork, carry out recycling of next regional self-bearing type combined steel formwork construction.
Among the present invention, in step (1) afterwards, can also realize leveling or arch camber requirement through adjustment self-bearing type combined steel formwork physical dimension.
Among the present invention, said in quick connection between horizontal brace rod and the self-bearing type combined steel formwork of bearing and limit bearing, all be to be connected on the truss.
The invention has the beneficial effects as follows:
(1) economic benefit: the present invention has cancelled the use of steel pipe scaffold; The whole inversion assembled self-bearing type combined steel formwork, the inverted self-bearing type combined steel formwork of formation, lifting of inverted self-bearing type combined steel slab integral and the whole construction in place of overturning on employing ground or the platform; Job practices cost of the present invention is compared with setting up full scaffold, traditional self-supported formwork job practices, and the template construction cost declines to a great extent;
(2) duration effect: the present invention is owing to need not set up scaffold; The whole inversion assembled self-bearing type combined steel formwork, the inverted self-bearing type combined steel formwork of formation, the lifting of inverted self-bearing type combined steel slab integral and the whole construction in place of overturning, the influence that does not receive lower-layer concrete intensity and build on employing ground or the platform; High efficiency, template construction speed significantly improves;
(3) practice thrift and environmental protection: the present invention is in implementation process, and the template accessory all adopts standard component, but subdivision recycle, form of structure adopts the self-bearing type combined steel formwork, need not extra interim support; Economical with materials reduces construction noise, and the site operation operating environment obviously improves.
(4) application value: adopt the present invention to solve and set up the difficult problem that finished product increases, the duration increase brings that full hall scaffold causes, and quick construction, safe and reliable, increase work efficiency, reduce engineering cost, have highly application value.
