Description
Technical field
This utility model relates to the constructing device of a kind of municipal works, particularly relates to a kind of pipe gallery sidewall built-in fitting solid
Determine device.
Background technology
Pipe gallery, is to build at Urban Underground, for concentrating the public tunnel laying municipal pipeline.Pipe gallery can have
Effect stops " slide fastener road " phenomenon, allows technical staff without excavated pavement repeatedly, just can rob all kinds of pipelines in piping lane
Repair, safeguard, extending capacity reformation etc., the Ye Shi present stage Party Central Committee and State Council support energetically and pay much attention to civilian infrastructure work
Journey.
The construction of present stage pipe gallery mostly is cast-in-situ reinforced concrete, and pre-embedded steel slab during civil engineering props up for follow-up each pipeline
Frame is installed, and owing to pipe gallery accommodates multiple municipal pipeline, comprises electric power, communication, radio and television, feedwater etc., and each pipeline needs
Hanging on piping lane medial wall, therefore support installs quantity greatly, also leads to the pre-embedded steel slab scale of construction big, and quantity is many.Pipe gallery is
Project of vital and lasting importance engineering, therefore, must accomplish accurately to control to installation of embedded parts, and takes reliable fixation to prevent skew,
To ensure to control within the scope of the tolerance that specification specifies its displacement, smooth deviation.
Municipal works cast-in-situ reinforced concrete construct in, for being embedded in the steel plate built-in fitting on reinforced concrete surface, its location with
Fixing usual processing method is: be embedded in template in order to built-in fitting location along built-in fitting surrounding nail by built-in fitting temporarily,
The dowel of built-in fitting is welded on the main muscle of reinforced concrete structure, fixing in order to built-in fitting.This built-in fitting fixed form exists
Problems with: 1, in concreting process, often occurs loosening even coming off in order to position the nail of built-in fitting, thus
Cause built-in fitting displacement, crooked and concrete surface not in quality problems such as same plane even submerge in concrete；2, filling
Slurry is with under the percussion vibrated, and reinforced concrete structure framework of steel reinforcement also can occur relative shift, thus will cause being welded in reinforcing bar
There is off normal the most therewith in the built-in fitting on skeleton；3, must etc. structure reinforcing bars skeleton colligation complete after could weld built-in fitting, and
Welding capacity is big, and speed of application is relatively slow, is unfavorable for parallel operations；4, built-in fitting and template surface laminating be not tight, insecure, by right
The structural safety of whole engineering leaves hidden danger, the use function of relevant device is caused significant impact, and it is repaired difficulty by the later stage
Spend big, long in time limit, costly；The 5 pipe gallery support settings built-in fitting scale of construction of being correlated with is big, and quantity is many, as the work of project of vital and lasting importance
Journey, prior art obviously can not solve problem.
