The invention reduces construction cost, and improves installation quality.
Description
Technical field
The present invention relates to the concrete road construction, relate in particular to the construction method of installation of concrete road type steel expansion joint.
Background technology
In municipal administration, highway and Bridge Construction, the type steel expansion joint construction is more and more general, and job practices also is varied, and construction quality is uneven.Some method inefficiency not only wherein, and the installation quality precision is not guaranteed yet.Therefore, in the execution control process, fail to embody efficient, convenient, characteristics accurately.Such as common are following two kinds of methods:
Method one is to adopt the method for the control planeness of shaped steel+guiding ruler that the shrinkage joint is installed:
1, shifts to an earlier date pre-buried shrinkage joint distribution reinforcement for the globality that guarantees concrete structure and shrinkage joint.
2, completely spread Polypropylence Sheet and yellow ground is filled to the asphalt surface course elevation of bottom at the bottom of preformed groove, the pitch that paves rolls.
3, according to the designing requirement unwrapping wire, cut out reserving good position, shrinkage joint flexible pavement, and clean out;
4, begin to install shaped steel.In road design horizontal wall inscription side slope point, type steel expansion joint overlapped points etc. shaped steel is set, and assurance shaped steel bottom contacts closely with flexible pavement, firm, utilize guiding ruler and clearance gauge to check whether the steel shrinkage joint flushes with road structure, and after meeting the requirements, adopt reinforcing bar that type steel expansion joint and shaped steel are welded, fixedly the shrinkage joint absolute altitude.
6, build steel fibrous concrete;
7, rubber fastening band is installed in form removal.
There is following point in this method:
1, after type steel expansion joint is fixed, can't again adjust its planeness.
2, can't again adjust after the local absolute altitude variation of type steel expansion joint that in work progress, causes having fixed.
The shaped steel magnitude setting is more when 3, constructing at long shrinkage joint, needs a large amount of manpower when shaped steel is set, and causes the waste of manpower.And the method carry out large batch of shrinkage joint when constructing simultaneously input manpower and materials larger.
4, type steel expansion joint difficulty when absolute altitude carries out trickle adjustment is large, and loaded down with trivial details.
Method two, the method that adopts the supporting fixing steel plate of type steel expansion joint to carry out planeness control is installed the shrinkage joint,
The main distinction of the method and method one is in the adjustment mode of absolute altitude:
Adopt the 3m guiding ruler to adjust deformed steel end face absolute altitude, utilize mortar, rubble etc. deformed steel to be fixed temporarily.
Fixing steel plate is fixedly welded on the pre-buried spacer bars of concrete structure.
The deficiency that wherein exists is: after deformed steel is temporary fixed, the absolute altitude of unavoidable deformed steel changes to some extent in this process, after finishing, the fixing steel plate welding can't again carry out the planeness adjustment to deformed steel, therefore cause the type steel expansion joint planeness to meet design requirement, cause during driving and jump the car sense, simultaneously, difficulty was large when type steel expansion joint carried out trickle adjustment at absolute altitude, and loaded down with trivial details.Further cause sexy shrinkage joint localized hyperthermia during a large amount of fixing steel plate welding, cause the shaped steel distortion, affect its application life.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides a kind of concrete road type steel expansion joint accurate mounting method.The present invention reduces construction machinery and constructor, greatly reduces construction cost, and has improved installation quality, has shortened the construction period.
For addressing the above problem, the accurate mounting method of a kind of concrete road type steel expansion joint, it comprises the following steps:
Step 3 according to the designing requirement unwrapping wire, cuts out reserving good position, shrinkage joint, and cleans out;
Step 4 adopts common nut and bolt, is welded into a shaped steel adjusting device, and described shaped steel adjusting device comprises bolt;
Step 5 is buried expansion bolt underground in steel concrete, fixedly the shaped steel adjusting device;
Step 6 is installed shaped steel, and tentatively fixedly the steel shrinkage joint checks with guiding ruler and clearance gauge whether the steel shrinkage joint flushes with road structure, after meeting the requirements, and the interval set bolt;
Step 7, assembling reinforcement installs template;
Step 8 is carried out planeness with guiding ruler and clearance gauge and is accurately checked, utilizes the shaped steel adjusting device to carry out the accurate leveling of planeness;
Step 9 is built steel fibrous concrete;
Step 10, rubber fastening band is installed in form removal.
The accurate mounting method of described concrete road type steel expansion joint, described shaped steel adjusting device comprises a framework, be screwed with a bolt from the top of this framework, also be screwed with a bolt from this framework below, this bolt is provided with two and lays respectively at the inside and outside nut of described framework.
The accurate mounting method of described concrete road type steel expansion joint, the bottom and upper segment of the framework of described shaped steel key regulating device are the nut that two two ends and framework dual-side weld together.
The present invention utilizes plain bolt and the simple and easy apparatus for regulating that shapes of nut, and by the height of bolt adjusting shaped steel, manufacture craft is simple, and is easy to make, and economic benefit is high, and construction quality easily guarantees.It is particularly convenient, easy to operate to use this method installation type steel expansion joint, and installation accuracy is controlled easily, in the similar engineering construction very high using value is arranged, and has larger popularization and application space.
