Problems solved by technology

[0003] At present, the temporary fixing measures adopted in the construction all need to rely on the side form to form the overall structure fixation or rely on the bottom form to fix the steel web through other structures. The steel web can only be adjusted after the bottom form is set out, and the side form or bottom form is under construction If there is any deflection in the center, the steel web will also deflect accord

Embodiment 1

[0026] Such as Figure 1~4 The schematic diagram of the temporary fixing structure of the corrugated steel web independent of the formwork shown in the present invention respectively includes a longitudinal steel brace 1, a first bent steel plate 2, a first reserved hole 3, a second reserved hole 4, a third reserved Retained holes 5, welded steel bars 6, fourth reserved holes 7, transverse steel braces 8, second bent steel plates 9 and corrugated steel web segments 10.

[0027] Taking a group of adjacent corrugated steel web segments 10 as an example, the specific structure of the present invention is described as follows:

[0028] Two corrugated steel web segments 10 are arranged adjacently, and two adjacent corrugated steel web segments 10 are arranged opposite to the two adjacent corrugated steel web segments 10 . Two adjacent corrugated steel web segments 10 are fixedly connected by longitudinal steel braces 1, and two opposite corrugated steel web segments 10 are fixedly...

Abstract

The invention discloses a corrugated steel web temporary fixation structure independent of a template. The corrugated steel web temporary fixation structure comprises a plurality of corrugated steel web sections, longitudinal steel supports and transverse steel supports; the multiple corrugated steel web sections are combined to form a square structure, every two adjacently-arranged corrugated steel web sections are fixedly connected through the corresponding longitudinal steel supports, and every two oppositely-arranged corrugated steel web sections are fixedly connected through the corresponding transverse steel supports; and the number of the longitudinal steel supports for connecting two adjacent corrugated steel web sections is two, and the two longitudinal steel supports are arranged in parallel. By means of the temporary fixation measures, the problem that during construction at present, steel webs are fixed through bottom dies or side dies, consequently, sampling wastes time, and plane deviations are caused on the steel webs before and after pouring is carried out is solved, and influences of the deviations of the steel webs on box girder stress are reduced.

Description

technical field [0001] The invention relates to a construction technology for temporarily fixing corrugated steel webs by cantilever pouring, in particular to a temporary fixing structure for corrugated steel webs independent of formwork. Background technique [0002] Comparing with the traditional prestressed concrete box girder bridge, corrugated steel web prestressed composite box girder bridge has developed rapidly in my country in recent years due to its advantages of lower dead weight, better seismic performance, high prestressing efficiency, and clear force. According to the needs of construction, the span gradually increases, and the weight of a single corrugated steel web can reach about 10t. The temporary fixing structure of the corrugated steel web has a great influence on the alignment and force of the steel web after pouring. [0003] At present, the temporary fixing measures adopted in the construction all need to rely on the side form to form the overall struct...
