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 large, precision and presentation quality poor, the seam of template spelling is many, piece imprecision, and running pulp, spillage phenomenon easily occur.And wooden form strength of parts is relatively low, composite rigidity is relatively little, and reinforce difficulty greatly, template is easily out of shape, and causes concrete pavement uneven.The panel plane integral rigidity that wooden form is combined in addition 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 integral hoisting.Complicated construction technique, technique progress is comparatively slow, and mechanized construction degree is relatively low, and labour intensity is large, and construction efficiency is low.The number of times that wooden form uses is relatively few, and in the process of processing, have certain loss, strength of parts is low, poor durability, and the number of turnover is few.A set of wooden form and reinforced liner can only apply a transformer station, and construction cost increases.
Summary of the invention
The object of the invention is to solve the weak point that above-mentioned prior art exists, provide that a kind of utilization rate is high, cost is low, saving resource, body of wall precision are 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, its special character is to comprise the following steps:
(1) fire wall basis is built
Carry out fire wall steel bar meter, reinforcing bar anchors in fire wall basis, test after adhesion of tendon and muscle after injury lattice through management, build fire wall base concrete, photoelectric measuring level is adopted during concrete leveling, strict control base concrete surface finish, error is less than 2mm, meets levelness and the verticality requirement of steel form installation;
(2) steel form installs
Steel form is with after electric polishing machine polishing, and brush twice template is cured, and prevent concrete from pasting steel form, after causing the demoulding, clear-water concrete affects outward appearance, and at template interface place, plastic sealing strip seals, mortar leakage prevention;
Concrete strength inspection is carried out with Schmidt hammer, reach can carry out next procedure construction during load bearing stength until base concrete intensity, unwrapping wire is carried out by design drawing, when steel form is installed, the line of ink marker that template end opening aims at bullet above basis positions, behind location, each built-up member of template are connected firmly, the levelness of laser level Control architecture, the verticality of transit Control architecture, two-sidedly reinforce, steel form is installed at twice simultaneously, and first time installs 3.1m, second time setting height(from bottom) 3.6m and bearing down on one, concrete is built equally at twice;
Do not re-use conventional steel fastener console mode scaffold, directly use the Special support reinforcing template of steel form field processing and fabricating, 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, strict control concrete proportioning, to ensure in work progress that surface layer is smooth, be strictly on guard against that leakage is shaken, owe to shake or cross to shake, prevent bubble and voids and pits phenomenon, fire wall is built at twice, first time concreting height 3.1m, second time builds height 3.6m and fire wall bears down on one.Adopt the mode of water seasoning, if special messenger waters, guarantee that concrete keeps moistening.
(4) second segment model sheetinstallat concreting.
The construction method of steel form fire wall of the present invention, has the following advantages:
(1) steel form making precision is high, and template plate width is large, decreases the seam of template spelling, and piece is tight, and running pulp, spillage phenomenon can not occur;
(2) steel form rigidity is large, not yielding, and it is convenient to reinforce, and the shaping concrete structure size of template is accurate, closely knit bright and clean;
(3) the panel plane integral rigidity that is combined into of steel form is strong, and panel combination becomes formwork inherently supporting member, more can improve integral rigidity and be convenient to integral hoisting supporting structure also can be made to simplify.Construction technology is simple, and technique progress is fast, and mechanized construction 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, and surface finish, verticality are good, concrete uniform color, reaches clear water concrete effect;
(5) steel form factory prefabricating processing, material less investment, loss is less, long service life, and strength of parts is high, good endurance, and the number of turnover is many.

Detailed description of the invention
Below provide the specific embodiment of the present invention, be used for being described in further detail formation of the present invention.
The construction method of steel form fire wall, comprises the following steps:
(1) fire wall basis is built
Carry out fire wall steel bar meter, reinforcing bar anchors in fire wall basis, test after adhesion of tendon and muscle after injury lattice through management, build fire wall base concrete, photoelectric measuring level is adopted during concrete leveling, strict control base concrete surface finish, error is less than 2mm, meets levelness and the verticality requirement of steel form installation;
(2) steel form installs
Steel form is with after electric polishing machine polishing, and brush twice template is cured, and prevent concrete from pasting steel form, after causing the demoulding, clear-water concrete affects outward appearance, and at template interface place, plastic sealing strip seals, mortar leakage prevention;
Concrete strength inspection is carried out with Schmidt hammer, reach can carry out next procedure construction during load bearing stength until base concrete intensity, unwrapping wire is carried out by design drawing, when steel form is installed, the line of ink marker that template end opening aims at bullet above basis positions, behind location, each built-up member of template are connected firmly, the levelness of laser level Control architecture, the verticality of transit Control architecture, two-sidedly reinforce, steel form is installed at twice simultaneously, and first time installs 3.1m, second time setting height(from bottom) 3.6m and bearing down on one, concrete is built equally at twice;
