Description
Technical field
The invention belongs to concrete construction mounting technology fields, and in particular to arrive formwork keel, more particularly a kind of use
In the formwork keel and its construction method of big section composite steel concrete column.
Background technique
With the increase of the high building structure number of plies, extended height, structural column internal force increases sharply, in Aseismic Design,
To guarantee that there is pillar certain ductility must control the axial compression ratio of pillar, the section of column is correspondingly required to increase, therefore big section
More and more to solve, building arrangements are difficult, actually make in large-span structure and earthquake territory application in tall buildings for Structural Steel Reinforced Concrete
The problems such as being reduced with area；
But in the actual construction process, since fashioned iron core causes conventional formwork difficulty to increase, conventional " Screw arbor with nut at both-ends adds
Solid model plate " need to will be fixed using mountain type due to outside the wooden a tree, used in making timber for boats, steel pipe after Screw arbor with nut at both-ends and fashioned iron core firm welding, but Screw arbor with nut at both-ends welds
Welding residual stress is generated in termination process, so that fashioned iron core is generated different degrees of horizontal and vertical contraction distortion, is directly affected type
The stress performance of steel core；Composite steel concrete column reinforcing bar is intensive, and screw rod and reinforcing bar welding difficulty are big, and welding quality requires high, inconvenience
In operation；As the super 2m × 2m of strengthening concrete column dimension, the wooden a tree, used in making timber for boats and steel tube framework bending resistance, shearing resistance, amount of deflection do not meet actual condition
It easily causes that quick-fried mould in concreting process, rise mould, at this moment needs to design Novel keel and formwork way solves big section stiffness
The problem of column formwork construction.
Summary of the invention
In order to overcome above-mentioned technical problem, the purpose of the present invention is to provide one kind to be used for big section composite steel concrete column
Formwork keel, the present invention is made of square steel and U galvanized steel snap-gauges, is suitable for the big section strength of the super 2m × 2m of different specification size
Property concrete column template, can be a set of multi-purpose in the cylinder of different big sectional dimensions is built, installation is simple, convenient disassembly, only needs
Two people can easily just carry out tightening operation, and when needing to dismantle, wedge-shaped iron is removed, four pieces of U galvanized steel snap-gauge natural separations,
Formwork system stability is high, and good forming effect, verticality, flatness are easy to control, and inner template is not necessarily to drilling, non-bolt after molding
Hole, perception are preferable.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of formwork keel for big section composite steel concrete column, including two piece of the first U galvanized steel snap-gauge and two pieces
