Description
Technical field
The present invention relates to a kind of fastening type cylindrical timber formwork concrete casting construction method, belong to technical field of buildings.
Background technology
Along with the development of skyscraper, various special-shaped buildings progressively increase, and cylinder is more and more applied in architectural design,
Cylinder construction uses template mainly to have cylindrical steel template, PVC plastic template, and steel shutterings pretends to be stupid heavily, needs bigger lifting to set
Standby lifting, wastes time and energy, though PVC template quality is light, but due to template threading defects, is easily caused circle arc error, gets
Cylinder qualification rate low, particularly interface position, it is generally required to secondary repair.For solve an above difficult problem, when cylinder is constructed I
Company uses buckle-type cylindrical wooden template, uses this template concrete formation surface to can reach the apparent mass of clear-water concrete, no
Need to carry out secondary again to plaster, and handle simple and easy to control, the most cost-effective but also decrease one working procedure, accelerate
Construction speed.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of convenient construction, can guarantee that construction safety and raising pour after coagulation
Soil property amount, and the fastening type cylindrical timber formwork concrete casting construction method of easily form removal.
Fastening type cylindrical timber formwork concrete casting construction method of the present invention, comprises the following steps:
1) colligation cylinder framework of steel reinforcement；
2) location: surveying column-form outer edge unwrapping wire, a diameter of needs of column-form outer edge pours the straight of cylinder outer edge
Footpath adds the template thickness of twice, is then respectively provided with spacer bar in cylinder framework of steel reinforcement upper, middle and lower, by spacer bar and circle
Post framework of steel reinforcement is with tying up a colligation together, and spacer bar uses two horizontal strokes two to erect reinforcement welding together；
3) template construct: template is wooden template, and template is made up of two semicircular template, one end of each half circle template all processes
Going out groove, the other end all processes the projection that matches with groove；
4) model sheetinstallat: when model sheetinstallat height is within 3m, uses the semicircle template assembly of monoblock, and by two semicircular mould
Together with plate and groove fasten to projection；When model sheetinstallat height is more than 3m, carry out dislocation lap joint installation；
5) template is in the cutting process of beam-column intersection position: in beam-column intersection position, cut template；
6) formwork reinforcement: every piece of template assembly all first passes through iron wire after completing carries out closing up Guan Bi, then reinforces with steel band, steel band
Being provided with an opening, opening part two ends are respectively provided with bolt block, when installing steel band, first follow closely on the circumference of the sustained height of template
Nail, steel band is placed on nail, and template is encased from its opening part, is tightened by the bolt block at opening part two ends with bolt；
7) template system entirety is fixed: add the lumps of wood in template periphery, and the lumps of wood is fixed by steel pipe, and steel pipe is fixed on scaffold,
Steel pipe distance between the upper and lower is 500～1500mm；
8) concreting: before concreting, builds platform with mortar bottom template, and height is 10～20mm, and template pours
Can primary concreting time within concrete seven m；Time highly more than 7m, pour at twice, pour latter 30～60 points for the first time
Clock carries out second time and pours；
9) form removal.
Wherein, in step 2 during location, total powerstation method of polar coordinates can be used to be accurately positioned；The length of spacer bar is can guarantee that steel
Tendon protective layer thickness is advisable, position, the accuracy of cover to reinforcement during to ensure that cylinder pours；
In step 6 install steel band time bolt time, each bolt degree of tightening to keep consistent, such guarantee steel band elasticity
Concordance and construction safety；
The lumps of wood in step 7 can use cross section to be foursquare cuboid wood, a length of 100mm, width and be highly 50mm,
By the lumps of wood, template system entirety is fixed, be possible not only to make template carry out perpendicular positioning, and being forced into of template can be made
One entirety, reaches the effect of second consolidation；
Spacer bar in described step 2 is set to 3 roads；Nail in step 5 uses 3～4, steel band between the upper and lower away from
From 200～300mm, can increase steel band and fix between neighbouring template, steel band level covers reinforces at interface position.
Wooden template in described step 3 is inside and outside uses epoxy resin overlay film.Smooth, waterproof and have certain breathability, beat
The concrete cylindrical gone out is the most smooth but also forming, vision and feel are splendid, and general effect is better than similar plain form.
It addition, template of the present invention can use high-quality birch poplar template.
The invention has the beneficial effects as follows:
1) plank sheathing light weight, using birch poplar is raw material, and intensity is big, general weight 40-45Kg of template of good toughness, highly 3m,
Two people cooperate can complete to install operation, compared with traditional steel form construction, shorten the construction period of 70%；
2) plank sheathing uses sizing column-form, uses unique convex groove design, make piece combine closely at template interface, anti-
Only running pulp, spillage, makes concrete demoulding the fastest but also attractive in appearance；
3) the inside and outside epoxy resin overlay film that uses of this typified form, smooth, waterproof and have certain breathability, the concrete circular got
Post is the most smooth but also forming, vision and feel are splendid, and general effect is better than similar plain form；
4) plank sheathing solves the difficult problem that steel form cannot arbitrarily cut, and arbitrarily can cut according to actual size, drops for construction party
Low difficulty of construction:
5) plank sheathing solve punching block, PVC template etc. because of self-defect cannot a lintel difficult problem.
