Description

Corrugated steel web suitable for various construction methods
Technical Field
The invention relates to the field of building construction, in particular to a corrugated steel web suitable for various construction methods.
Background
Compared with the traditional bridge, the corrugated steel web composite bridge has the advantages of light dead weight, web cracking prevention, good mechanical property and the like, is widely applied to bridge construction, mostly adopts a cantilever hanging basket cast-in-place construction method for large-span corrugated steel webs, and mainly comprises a synchronous hanging basket construction method and an asynchronous hanging basket construction method in the conventional construction method. However, the construction method adopted by the existing corrugated steel web is single, and different project progress requirements and different project construction requirements are difficult to deal with.
Disclosure of Invention
The invention aims to provide a corrugated steel web suitable for various construction methods to solve the technical problems.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a wave form steel web suitable for multiple construction method, includes the trompil steel sheet, runs through reinforcing bar, upper limb flange board, wave form steel web, perforation reinforcing bar, lower limb flange board, upper limb flange board and lower limb flange board weld respectively in wave form steel web upper and lower end, wave form steel web bottom is equipped with a plurality of buryying formula shear force holes, the perforation reinforcing bar runs through the wave form steel web through buryying formula shear force hole, the trompil steel sheet welds on the upper limb flange board, is equipped with a plurality of mounting holes on the trompil steel sheet, the perforation reinforcing bar passes the mounting hole.
Preferably, 1-3 rows of concrete grout holes are reserved on the lower flange plate to facilitate concrete pouring.
Preferably, the perforated steel plates are arranged in pairs and welded on two sides of the upper flange plate in parallel, and the inner diameter of each mounting hole is slightly larger than the radius of the through steel bar.
Preferably, the inner diameter of the embedded shear hole is slightly larger than the radius of the perforated steel bar.
Compared with the prior art, the invention has the following advantages: the invention is provided with the lower flange plate, can be simultaneously suitable for synchronous and asynchronous construction methods, and flexibly selects a proper construction method according to different characteristics and requirements of projects.
Drawings
FIG. 1 is a schematic view of a corrugated steel web suitable for various construction methods according to the present invention.
In the figure: 1. the concrete flange plate comprises a perforated steel plate, 2 parts of penetrating steel bars, 3 parts of upper flange plates, 4 parts of corrugated steel webs, 5 parts of perforated steel bars, 6 parts of lower flange plates, 7 parts of mounting holes, 8 parts of embedded shear holes, 9 parts of concrete grout turning holes.
Detailed Description
The invention is explained in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, a corrugated steel web suitable for various construction methods includes an open-pore steel plate 1, a through reinforcement 2, an upper flange plate 3, a corrugated steel web 4, a perforated reinforcement 5, and a lower flange plate 6, where the upper flange plate 3 and the lower flange plate 6 are respectively welded to the upper end and the lower end of the corrugated steel web 4, a plurality of embedded shear holes 8 are formed in the bottom of the corrugated steel web 4, the perforated reinforcement 5 penetrates through the corrugated steel web 4 through the embedded shear holes 8, the open-pore steel plate 1 is welded to the upper flange plate 3, a plurality of mounting holes 7 are formed in the open-pore steel plate 1, and the through reinforcement 2 penetrates through the mounting holes 7.
1-3 rows of concrete grout-turning holes 9 are reserved on the lower flange plate 6 to facilitate concrete pouring. Trompil steel sheet 1 sets up in pairs, parallel weld in the both sides of upper flange board 3, 7 internal diameters of mounting hole slightly are greater than the radius of penetrating through 2 reinforcing bars. The inner diameter of the embedded shear hole 8 is slightly larger than the radius of the perforated steel bar 5.
The working principle of the invention is as follows: a corrugated steel web plate suitable for various construction methods is provided, and due to the fact that the corrugated steel web plate comprises a lower flange plate, a special hanging basket can be manufactured by utilizing the self-bearing characteristic of the corrugated steel web plate, and asynchronous construction can be conducted. The invention can be used for the synchronous construction and asynchronous construction method of the corrugated steel web, and can flexibly select the construction method according to the project site condition in the concrete engineering construction so as to improve the construction efficiency and save the construction cost.
The foregoing is a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that variations, modifications, substitutions and alterations can be made in the embodiment without departing from the principles and spirit of the invention.
