Construction method of opposite-pull-free and adjustable column formwork concrete

Abstract

The invention discloses a construction method of opposite-pull-free and adjustable column formwork concrete. The construction method comprises the following steps that firstly wooden I-shaped beam system formworks are assembled for standby application; then setting out and positioning are conducted on a column, after level finding is conducted, the assembled formworks are hoisted to the preset positions of a column formwork, and the two formworks are fixed together by using an external corner cable-stayed seat; secondly, the perpendicularity of the formworks is adjusted by using steel pipes and inclined struts, and the to-be-poured concrete column formwork is formed; when the column concrete section of the upper layer of a structure is changed, the section of the column formwork can meet the requirements by adjusting the connection positions of back edges and the number of wooden beams; and finally concrete pouring is conducted. The construction method has the beneficial effects that opposite-pull screws are saved, the standardness for pouring the column section is high, the size can be changed according to different column sections, materials are saved, waste is reduced, and meanwhile the construction method has the advantages that assembling is convenient, dismounting and mounting are convenient, and the rigidity is high.

Description

technical field [0001] The invention relates to the technical field of formwork construction methods, in particular to a construction method for formwork concrete with adjustable columns without opposite tension. Background technique [0002] Since the traditional column formwork generally uses wooden squares, steel pipes, connectors and other on-site loose assembly, this assembly is not easy to control, and the on-site materials are not easy to manage, which is easy to cause loss and loss; at the same time, if the on-site assembly is not good, it is easy to cause pouring During the process, mold running, mold expansion, mold explosion and other phenomena, if the phenomenon of mold running is caused, the loss of concrete materials for the project will be more serious. [0003] At the same time, when the cross section is changed, the steel formwork needs to be cut, and the loose materials such as wooden squares also need to be changed, and because the columns are relatively h...

[0002] Since the traditional column formwork generally uses wooden squares, steel pipes, connectors and other on-site loose assembly, this assembly is not easy to control, and the on-site materials are not easy to manage, which is easy to cause loss and loss; at the same time, if the on-site assembly is not good, it is easy to cause pouring During the process of mold running, mold expansion, mold explosion and other phenomena, if mold running is caused, the loss of concrete materials in the project will be more serious

[0003] At the same time, when the cross section is changed, the steel formwork needs to be cut, and the loose materials such as wooden squares also need to be changed, and because the columns are relatively high, the number of pull screws is also relatively large, resulting in a serious waste of tie rod materials, that is, waste of work and scrap
