Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0049] Such as Figure 1 to Figure 12 As shown, the high pier self-elevating outer frame turning device of the present invention includes an outer support system 10, a telescopic device 20, an upper formwork system 42 and a lower formwork system 41; the upper formwork system 42 is located in the lower formwork system 41 the top of

[0050] Both the upper formwork system 42 and the lower formwork system 41 include a formwork 40 that surrounds the pouring cavity of the high pier of the bridge; 13. The reinforced horizontal back flutes 13 on two adjacent formworks 40 are all connected by reinforced horizontal back flute connectors 15, so that the reinforced horizontal back flute 13 is tightly hugged on the outer surface of the template 40;

[0051] The upper and lower ends of each template 40 of the upper formwork system 42 are provided with an outer sup...

Abstract

The invention discloses a high bridge pier self-lifting outer frame over-form device which is simple in structure, can enhance over-form safety and improves over-form efficiency. The over-form device comprises outer support systems, telescopic devices, an upper formwork system and a lower formwork system. The upper formwork system is located above the lower formwork system. The upper formwork system and the lower formwork system both comprise a layer of formworks forming a high bridge pier pouring cavity. The outer surface of the formworks of the upper formwork system and the outer surface of the formworks of the lower formwork system are both provided with reinforcing transverse back ridges. The reinforcing transverse back ridges on every two adjacent formworks are connected through reinforcing transverse back ridge connecting pieces, so that the reinforcing transverse back ridges tightly hold the outer surface of the upper layer formwork system. The upper end and the lower end of each formwork in the upper layer formwork system are both provided with one outer support system. Each outer support system comprises a crank arm beam, a straight beam and a vertical guide column. The over-form device 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 mold turning device for a high bridge pier, in particular to a mold turning device for a self-elevating outer frame of a bridge high 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 construction of othe...
