Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0058] Such as Figure 1 to Figure 12 Shown, the bridge high pier self-elevating outer frame turning over construction technology of the present invention comprises the following steps:

[0059] 1) Formwork installation, pouring of upper and lower concrete;

[0060] Install a layer of formwork 40 surrounding the pouring cavity of the high pier of the bridge to form the lower formwork system 41, and pour the first layer of concrete after the installation is completed; however, install another layer of formwork 40 above the lower formwork system 41 to form the pouring cavity of the high pier of the bridge to form The upper formwork system 42; however, the pouring of the second layer of concrete is carried out;

[0061] The outer surfaces of the formwork of the upper formwork system 42 and the lower formwork system 41 are all provided with reinforced hor...

Abstract

The invention discloses a high bridge pier self-lifting outer frame over-form construction technology which is simple in construction, high in construction safety and high in construction efficiency. The over-form construction technology comprises the following steps that firstly, formworks are installed, and upper layer concrete and lower layer concrete are poured; secondly, outer support systems and telescopic devices are installed; thirdly, the lower layer formworks are detached, lifted and installed; fourthly, the outer support systems are lifted; fifthly, the telescopic devices freely side downwards to an upper layer formwork system to be connected with formworks of the upper layer formwork system. The over-form construction technology is easy to operate, quality is controlled more easily, the speed is higher, cost is lower, and safety is higher.

Description

technical field [0001] The invention relates to a form-turning device for a high bridge pier, in particular to a form-turning construction process for a self-elevating outer frame of a high bridge pier. Background technique [0002] Known, the method for formwork construction of bridge high pier at present has: sliding formwork construction, climbing formwork construction, slide-turning combination construction, climbing-turning combination construction, turning-over construction, support turning-over construction. Sliding formwork, climbing formwork, combination of sliding and turning, and combination of climbing and turning are all technically required to install special embedded parts in the pier concrete under construction as load-bearing components when lifting the formwork. These embedded parts have high requirements on quality and forming process, and the installation and positioning are precise and strict. The construction of embedded parts interferes with the constr...
