Description
Technical field
The present invention relates to the construction method of steel form fire wall, belong to construction method technical field.
Background technology
It is high that normal wood template fire wall makes finished product, and the wasting of resources is big, and precision and presentation quality are poor, template spelling
Seam is many, piece imprecision, is susceptible to running pulp, spillage phenomenon.And plank sheathing strength of parts is relatively low, composite rigidity phase
To less, reinforcing difficulty greatly, template is easily deformed, and causes concrete topping uneven.The panel that additionally plank sheathing is combined into is put down
Face integral rigidity is told somebody what one's real intentions are, and panel combination becomes formwork load-bearing strength own little, and needs support is reinforced, and is not easy to entirety and hangs
Dress.Complicated construction technique, technique progress is relatively slow, and mechanized construction degree is relatively low, and labour intensity is big, and construction efficiency is low.Wood
The number of times that template uses is the fewest, has certain loss during processing, and strength of parts is low, poor durability, the number of turnover
Few.A set of plank sheathing and reinforced liner can only apply a transformer station, and construction cost increases.
Summary of the invention
It is an object of the invention to solve the weak point that above-mentioned prior art exists, it is provided that a kind of utilization rate is high, cost
Low, save that resource, body of wall precision is high, the construction method of the steel form fire wall of appearance looks elegant.
The present invention is achieved by the following technical solutions:
The construction method of steel form fire wall, it is characterized in that and comprises the following steps:
(1) fire wall basis pours
Carrying out fire wall steel bar meter, reinforcing bar anchors in fire wall basis, after adhesion of tendon and muscle after injury lattice are tested in management, pours the fire prevention wall base
Plinth concrete, uses photoelectric measuring level, strict control base concrete surface smoothness during concrete leveling, error is less than 2mm,
Meet levelness and perpendicularity requirement that steel form is installed；
(2) steel form installs
After steel form is polished with electric polishing machine, twice template of brush is cured, prevents concrete from pasting steel form, causes the demoulding
Rear clear-water concrete affects outward appearance, seals with plastic sealing strip, mortar leakage prevention at template interface；
Carry out concrete strength inspection with reisilometer, reach to carry out lower road work during load bearing stength until base concrete intensity
Sequence is constructed, and carries out unwrapping wire by design drawing, and when steel form is installed, the line of ink marker of template end opening alignment basis bullet above positions,
Behind location, assembly parts each to template are connected firmly, the levelness of laser leveler Control architecture, theodolite Control architecture vertical
Degree, two-sided reinforces simultaneously, and steel form is installed at twice, installs 3.1m for the first time, for the second time setting height(from bottom) 3.6m and bearing down on one, coagulation
Soil pours the most at twice；
Not in use by conventional steel fastener console mode scaffold, the Special support of steel form field processing and fabricating is directly used to add
Solid model plate, and erection construction operating platform, door-type scaffold coordinative construction.
(3) concreting and maintenance
After owner's representative in building site and supervisor's acceptance(check), prepare concreting, strictly control concrete matched
Ratio, in work progress, surface layer to be ensured is smooth, is strictly on guard against that leakage is shaken, owed to shake or cross to shake, prevents bubble and voids and pits phenomenon,
Fire wall pours at twice, and the height 3.1m of concreting for the first time, second time pours height 3.6m and fire wall bears down on one.Use
The mode of water seasoning, if special messenger waters, it is ensured that concrete keeps moistening.
(4) second segment model sheetinstallat concreting.
The construction method of the steel form fire wall of the present invention, has the advantage that
(1) steel form makes precision height, and template plate width is big, decreases the seam of template spelling, and piece is tight, will not occur
Running pulp, spillage phenomenon；
(2) steel form rigidity is big, is unlikely to deform, and it is convenient to reinforce, and the xoncrete structure size of template shaping is accurate, closely knit light
Clean；
(3) the panel plane integral rigidity that steel form is combined into is strong, and panel combination becomes formwork inherently supporting member, more can
Raising integral rigidity is easy to integral hoisting also can make supporting structure simplify.Construction technology is simple, and technique progress is fast, and mechanization is executed
Engineering degree is high, and labour intensity is low, accelerates construction speed, improves work efficiency 2 ~ 3 times；
(4) steel form absorption affinity is little, and the demoulding is easy, and concrete negative and positive rounding of angle angle is effective, surface smoothness, perpendicularity
Good, concrete uniform color, reach clear water concrete effect；
(5) processing of steel form factory prefabricating, material less investment, be lost less, and service life is long, and strength of parts is high, resistance to
Property is good for a long time, and the number of turnover is many.
Accompanying drawing explanation
The construction method block diagram of the steel form fire wall of Fig. 1: the present invention.
Detailed description of the invention
The detailed description of the invention of the present invention given below, is used for being described in further detail the composition of the present invention.
The construction method of steel form fire wall, comprises the following steps:
