Description
Technical field
The invention belongs to engineering secondary structure field, especially relate to one and exempt from the pre-buried combination anchor of mantle fiber wall lacing wire
Device and construction method.
Background technology
The use of architectural engineering wall lacing wire experienced by the longest developmental stage, was mainly in the portion having secondary structure in the past
Wall lacing wire is welded, owing to a variety of causes is the most superseded after position pre-buried wall lacing wire in advance or pre-embedded steel slab.Present stage architectural engineering masonry
In structure construction, the mounting means of masonry wall lacing wire mainly has two kinds:
One, steel planting method: steel planting technology after i.e. using, owing to being to hole in concrete, is easily generated the most several
Individual problem: 1) hole owing in wall or post, reinforcement location affects easy off normal；2) in boring, lime-ash can not thoroughly be cleaned out；3)
After bar planting, the bending of colloid firm time deficiency wall lacing wire, easily loosens.Qualification rate after bar planting is relatively low, owing to above influence factor builds
Body structure and agent structure binding site are easily generated crack, and construction quality can not be guaranteed.
Two, embedded sleeve barrel method: the sleeve combination part of pre-buried strap internal thread in concrete, after concrete blinding is removed, installs
Wall lacing wire with screw thread.On-the-spot reinforcing bar just can use after needing mantle fiber, by on-the-spot processing conditions affected overlapped wall lacing wire screw thread with
Embedded sleeve barrel screw thread can not good match consistent, installation quality is difficult to ensure, simultaneously as building structure body of wall is numerous, on-the-spot
Wall lacing wire mantle fiber workload is huge, it is impossible to meet construction speed requirement.
The patented technology authorized is learnt by retrieval:
The embedded sleeve barrel assembly post embedding wall lacing wire of Chinese invention patent description Patent No. CN201210570158.3 is executed
Work method, the method is, before the concreting of lacing wire position, by design requirement, sleeve assembly is embedded in xoncrete structure
Wall lacing wire position, and screw on closure plastic plug at each sleeve ends, after concreting completes, with screwdriver by sleeve
The closure plastic plug of end screws out, and is then screwed in mantle fiber by wall lacing wire, then is tightened with sleeve by wall lacing wire with spanner, makes wall draw
Muscle and sleeve are integral by screwed connection.The method is to xoncrete structure not damaged, simple installation, and quality inspection is convenient.Should
Method shortcoming is: 1) on-the-spot wall lacing wire mantle fiber workload is huge；2) embedded sleeve barrel installation accuracy requires height, as installation site is forbidden
Really, cost after concreting and manually pick chisel sleeve portion, destroy xoncrete structure.
The method for mounting anchor tendon penetrated mechanically of Chinese invention patent description Patent No. CN02120816.6, the method
It is to use wall lacing wire one end to be fabricated to enlarged footing mantle fiber, simultaneously overcoat sleeve, during installation, first the boring of lacing wire position need to be set,
Scum silica frost and dust in cleaning eye, fill in lacing wire enlarged footing part and sleeve bosom, cavity, tighten the nut of lacing wire, make expansion
Head struts sleeve, and is integrated with xoncrete structure swelling.The method has reliable in quality, is not affected by field condition, installs
Convenient.The method shortcoming is that wall lacing wire need to be fabricated to enlarged footing mantle fiber, does not possess on-the-spot processing conditions simultaneously, adds labour movement outside the venue
Defeated expensive.
The pull rod expansion screw bolt post embedding wall lacing wire of Chinese invention patent description Patent No. CN200810151890.0 is executed
Work method, the method is to hole on the concrete of lacing wire position, loads special pull rod expansion screw bolt, inserted by wall lacing wire in hole
Enter in the countersunk head hollow bolt bar of pull rod expansion screw bolt, make wall lacing wire expand with pull bar by screwing the nut of pull rod expansion screw bolt
Swelling is integrated between bolt and between wall lacing wire and xoncrete structure hole, and the method is simple to operate, accurate positioning, the suitability
By force.The method shortcoming is: 1) being affected by boring, between expansion bolt and concrete, anchor force is poor；2) boring destroys concrete afterwards
Easy damaged structure reinforcing bar in structure, and boring procedure.
Summary of the invention
In view of this, it is contemplated that propose one to exempt from mantle fiber wall lacing wire pre-buried combination anchor device and construction method, no
Need that boring is installed i.e. anchor with wall lacing wire, it is ensured that quality, it is not necessary to be that wall lacing wire mantle fiber or do expands at the construction field (site)
The work of head, pre-buried anchor is installed reliable, and after form removal, anchor spacing is consistent, and outward appearance is neatly unified, and can improve
The installation rate of wall lacing wire and quality.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
