Technical field
It the utility model is related to railway engineering Bridge pier shaft reinforcement construction field, more particularly to a kind of Thin-wall Hollow Pier pier
The positioning auxiliary device of body reinforcing bar.
Background technology
With the rapid development of economy, China achieves great achievement in railway infrastructure construction field, and railway leads to
Car kilometer reaches 120,000 kilometers, and wherein high-speed railway mileage open to traffic is up to more than 20,000 kilometers.
Bridge is the important component of railway, modern in railway is built, and the proportion of bridge is increasing, is also obtained fast
The development of speed.Built up at present and had many in the bridge built, for example, built up System for Wuhan Tianxingzhou Yangtze River Bridge, Nanjing
Foundations of Dashengguan Changjiang River Bridge, the long bridge Beijing-Shanghai express railway pellet Qazz bridge of the first in the world up to 164.851km.The success of these bridges
Build and not only indicate that China obtains great achievement in terms of Bridge Design, while also demonstrate China in bridge construction field
Achieve great achievement.
At present, the railway engineering duration is generally 4 to 5 years, high to construction period, and pier shaft height is big in more than 30m bridge pier
Part is designed for thin-walled hollow, long construction period, is priority control engineering, need to improve constantly efficiency of construction to ensure the duration.
Railway engineering is poured using template when carrying out Thin-wall Hollow Pier pier construction, manually adjusts Thin-wall Hollow Pier pier shaft reinforcing bar
Method, because Thin-wall Hollow Pier pier shaft reinforcing bar is closeer more, with over-form construction, pier shaft highly increases, and pier shaft section constantly becomes
To change, bar spacing adjusts therewith, and this process not only requires a great deal of time, human and material resources, and construction cost height,
Speed is slow, therefore huge in quantities and in the case that the duration is nervous, and this method can not meet the requirement of construction speed.
More rapid and better to ensure Thin-wall Hollow Pier pier shaft reinforcement construction quality, ensure Thin-wall Hollow Pier pier shaft reinforcement installation
The necessary quick, completion of high quality, needs a kind of positioning auxiliary device of pier shaft reinforcing bar badly to ensure construction period and quality.
Utility model content
In order to solve the above technical problems, the purpose of this utility model be to provide it is a kind of simple in construction, swift to operate and can
Accelerate the positioning auxiliary device of the Thin-wall Hollow Pier pier shaft reinforcing bar of Thin-wall Hollow Pier pier shaft reinforcement installation speed.
The positioning auxiliary device of Thin-wall Hollow Pier pier shaft reinforcing bar of the present utility model, including positioning plate body, the location-plate
The length of body is provided with several screens semicircular openings to side, and the bore of the screens semicircular opening is 20-35mm, adjacent screens semicircle
The center spacing of mouth is 10-20cm, and for the positioning plate body along plate body length to several fixing devices are fixed with, several fix dress
Put on the same line.
Further, the fixing device is made up of bolt with the nut for being screwed in the bolt end.
Further, the quantity of the fixing device is 3.
Further, the positioning plate body is rectangle steel plate.
By such scheme, the utility model at least has advantages below：The positioning auxiliary of Thin-wall Hollow Pier pier shaft reinforcing bar
The positioning plate body of device, with mutually being fixed with template to limit thickness of concrete cover, ensures positioning plate body not by fixing device
Change shape, do not produce displacement, in concreting process, screens semicircular opening carries out spacing and further limit to pier shaft main reinforcement
The spacing of main reinforcement is made, that is to say, that on the premise of the installation of pier shaft main reinforcement, welding quality is ensured, realize main reinforcement
Fast Installation, the purpose not being subjected to displacement, accelerate speed of application, and whole constructing operation process simple and flexible, security
It is higher, the quantity and labor intensity of workmen during reinforcement installation are reduced, and then reduce cost.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
