Description
Technical field
The invention belongs to building field, specifically the construction method of skyscraper pipeline enclosure.
Background technology
Pipeline enclosure is a requisite function room in building, is mainly used to arrange plumbing, fire-fighting, heating and ventilating pipeline and the cable pipeline etc. that in building, need. Pipeline enclosure is owing to need to laying more pipe laying, and designing unit is generally designed to the floor of pipeline enclosure reinforcing bar and as usual installs, and after pipeline installation, builds with high one-level slightly expanded concrete again. This kind of way, pipeline can bring secondary to set up support for shuttering after installing, install that template difficulty is large, expense is high, and tube circumference easily causes the hidden danger of quality such as seepage, top board out-of-flatness.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, a kind of construction method of skyscraper pipeline enclosure is provided, this method makes full use of steel bar truss floor support plate or prestressed concrete overlapped slab self rigidity, directly be routed on beam, carry out after simple reinforced bar engineering just directly casting concrete, substituted template completely, template erection and demolition works are saved, greatly improve floor slab construction efficiency, accelerated progress, ensured construction quality.
For solving the problems of the technologies described above, the invention provides a kind of construction method of skyscraper pipeline enclosure, comprise following concrete steps:
(1) main structure construction: main building when construction, floor is not constructed and made cavity, and pipeline enclosure is made to piping shaft, treats that agent structure form removable, floor cleared up, and carries out next process;
(2) angle steel is installed: on former xoncrete structure, the position from structure floor face toward next thickness of slab, installs equal leg angle, adopts setscrew to fix, and angle steel adopts spirit level to carry out horizontal plane control while installation, and guarantee angle steel is installed level;
(3) steel bar truss floor support plate blanking: according to piping shaft size, carry out the blanking of steel bar truss floor support plate by every limit size reduction 10～20mm, steel bar truss floor support plate lap width on angle steel is 50～75mm;
(4) pipeline installation site perforate: taking the center of pipe laying in construction drawing as the center of circle, increase 5mm again draw circle as radius taking the radius of pipe laying, carry out cut hole on steel bar truss floor support plate, cut hole adopts special circular cutter cutting regular;
(5) old concrete dabbing: because piping shaft periphery concrete is first casting concrete, in order to be combined with pipeline enclosure floorslab concrete, avoid cracking, above angle steel scope concrete must be carried out to dabbing, before secondary casting concrete, also need water moistening, brush by interfacial agents or cement mortar;
(6) pipeline is installed with steel bar truss floor support plate and is installed: pipeline carries out the installation of steel bar truss floor support plate when installation, adopt two laser plummets steel bar truss floor support plate to be positioned simultaneously, guarantee that pipeline center is consistent with steel bar truss floor support plate perforate center, when pipeline can not be installed simultaneously, can stay a floor support plate not install every 3～5 layers, so that pipe laying can be conveniently through floor support plate;
(7) bar planting, assembling reinforcement: after pipeline installation, at the enterprising andante reinforcing steel implant of piping shaft circumferential concrete, reinforcing bar size, bar planting spacing are identical with former designing requirement, are then connected with floor support plate reinforcing bar binding;
(8) concreting: after the hidden acceptance(check) of reinforcing bar, carry out concreting, concrete adopts from mixed concrete, carry out vertical transport by construction elevator, adopting trolley to carry out horizontal transport puts in place, while building, between tube circumference, floor support plate and former concrete, gap vibrating head vibration compacting, prevents percolating water.
For the purpose of describing the problem, below to the construction method of skyscraper pipeline enclosure of the present invention all referred to as this method.
Described in this method, steel bar truss floor support plate is that the reinforcing bar in floor is become to steel bar girder in factory process, and by steel bar girder and the integrally welded gang form of zinc-plated profiled sheet. This method takes full advantage of steel bar truss floor support plate self rigidity, is directly routed on beam, carries out after simple reinforced bar engineering just directly casting concrete, has substituted template completely, has saved template erection and demolition works, has greatly improved floor slab construction efficiency; On steel bar truss floor support plate, unify perforate, carry out centralized positioning with laser plummet, well ensured the quality that pipeline is installed; Do not need to cut off the reinforcing bar on floor, accelerated progress, ensured construction quality.
Steel bar truss floor support plate described in this method can replace with prestressed concrete overlapped slab, prestressed concrete overlapped slab is the prefabricated a kind of version combining with cast-in-place concrete, that cast-in-place concrete layer is made on prestressed thin slab, the cast-in-place concrete layer in prestressed thin slab (thick 5～8cm) and top is combined into as a whole, jointly works. The main muscle of prestressing force of prestressed thin slab is the main muscle of laminated floor slab, and cast-in-place concrete layer in top only configures negative reinforcement and distributing bar. Prestressed thin slab, as the bed die of cast-in-place concrete layer, needn't be cast-in-place concrete layer support shuttering, and prestressed thin slab bottom surface be smooth, and plate stitches after treatment, and ceiling can no longer be plastered.
