Description
Technical field
The present invention relates to the device that a kind of cast-in-situ concrete is built, be specially comprehensive gymnasium tapered pole outer decorative layer template and construction method thereof.
Background technology
In the face of the special-shaped component of large space, often select to design and produce typified form by professional template producer, as set shaped steel formwork, specialized factory's design advantage is that template system is more accurate, Stability Analysis of Structures, construct also more convenient, but construction costs is higher, typified form also has its limitation simultaneously, run into irregular structure component, on a production line also just cannot mechanization production, just there is very large difficulty in specialty template processing and fabricating, cannot deal with problems, the fabrication cycle of typified form is longer in addition, generally can take certain duration, typified form can not again repeatability, also data can be caused to waste.Therefore, how to find applicable tapered pole outer decorative layer template and construction method thereof, become in building engineering construction the technical problem being badly in need of solving.
Summary of the invention
The present invention is directed to problem above, devise a kind of template for the construction of tapered pole outer decorative layer and corresponding construction method thereof.
Concrete solution is: comprehensive gymnasium tapered pole outer decorative layer template, outer decorative layer template is positioned at outside outer decorative layer, described outer decorative layer template comprises cylinder template and cone template, and the circular end face of cylinder template is the bottom surface of cone template; Outer decorative layer template comprises: double-layer back plate, main joist channel-section steel back cord, secondary joist channel-section steel, a few word beam back cord, square steel pipe and Screw arbor with nut at both-ends, double-layer back plate is lined with three-ply board towards the one side of decorative layer, one end of Screw arbor with nut at both-ends is anchored on taper concrete column, main joist channel-section steel back cord, secondary joist channel-section steel, a few word beam back cord, square steel pipe and double-layer back plate is fixed on taper concrete column respectively.
Further, the double-layer back plate of described outer decorative layer template is the thick wooden form of double-deck 15mm, and double-layer back plate is lined with the thick three-ply board of 3mm towards decorative layer one side, forms the lines with wood grain effect; The wooden form of double-layer back plate is thin-walled Ascast finish concrete template with wood grain, vertical 40 × 60 × more than the 2 word beam back cords of double-layer back plate backing, and horizontal direction arranges 8# channel-section steel 500 as horizontal secondary joist, and back cord adopts two 14# channel-section steel as main joist; Screw arbor with nut at both-ends is three-stage screw.
The invention also discloses the construction method of comprehensive gymnasium tapered pole outer decorative layer template, comprise the steps:
1) check the physical dimension of having built tapered pole: must be simulated by entity, and field measurement actual quantities errorless after, in-depth and the processing of template can be carried out;
2) in conjunction with drawing and check size determination template shop detail drawing: according to the field data measured, in conjunction with drawing, carry out datumization setting-out, determine final template shop detail drawing;
3) template construct and assembled: template construct should be constructed in strict accordance with the material required by scheme, to ensure enough intensity.
4) template bolt perforating: bolt hole spacing due to tapered pole complex-shaped, accurately cannot draw expanded view, so must the arrangement of field lofting bolt hole, setting-out layout viewing, after each side confirms, can carry out punching work.Punching diameter control is at 25mm, so that the angle of adjustment segmented screw carries out reinforcement by connection.
5) template first time is in place: on-the-spot put sample well according to reinforcement location, template highest and lowest portion line is aimed to carry out template temporary fixed, and on pillar, arrange temporary support bar, ensures that template does not move.And protect temporary fixed point, in place to ensure second time;
6) along template prepared screw-bolt hole to structural column perforating: along template bolt hole to pillar perforating, perforating degree of depth 300mm, arranges mark during perforating on drill bit, ensures that the perforating degree of depth is accurate;
7) template is given up the throne: utilize the movable pulley of template itself and crane to withdraw from template, must utilize the suspension hook position in template, and command lifting by special messenger, forbid template to collide outrigger and building when noting handling;
8) implant segmented screw rod: can bar planting after noting bolt hole to clean out before implanting segmented screw rod, bar planting should meet the requirement of concrete structure post-anchoring technology;
9) template second time in place: template second time in place, ensure that primary template contral point does not change, guarantee twice in place identical.
10) form removable: two days strippings after concreting completes, removes from top to bottom, and crane hangs up properly suspension hook → carry out temporary support → dismounting primary and secondary skeletal frame → dismounting temporary support → lifting demoulding.
Further, in described step 3), form surfacing assembled complete after, subsides three-ply board before, quadrat sampling must be measured on template entity, setting-out result must be obtained, management, school side, design and construction over contract side can carry out the splicing of three-ply board after confirming, after three-ply board has spliced, jointly confirmed by management, school side, design and overall budget, after getting the nod, can subsequent construction be carried out in the scene of dropping into.
Further, in described step 4), template perforating adopts target drill from the outside perforating in three-ply board side, avoids three-ply board damaged.
Further, in described step 9), all templates should be checked in advance before concreting, to all have the position foamed glue in space close avoid running pulp.
Further, in described step 10), during form removal, operating personnel should stand in safe place, to avoid security incident; Should trying not during form removal, it is too urgent to overexert, and forbids firmly to pound with sledgehammer and crowbar firmly to strike, in order to avoid concrete surface or template are damaged.
Further, in described step 10), the template pulled down and accessory thereof, forbid disorderly to throw to throw out without care, special messenger should be had to scoop out transmission, stack by appointed place, and cleaning in time, maintenance and brush interleaving agent, use in order to turnover.
Further, in described step 10), in form removal process, during as found that concrete has quality problems affect structural safety, should stop removing, after treatment, just can continue dismounting.
Beneficial effect: wooden form panel and shaped steel keel cooperatively interact, be easy to assembled, be applicable to the structural element that moulding is changeable, in reinforcing with under supporting reasonable effective condition, stiffness by itself can meet fixing needs, the molding effect of component meets design requirement, and plate body system is relatively low relative to typified form cost.
