Abstract
The invention relates to a concrete constructional column, in particular to a concrete constructional column capital, and provides a capital inverted-triangular formwork erecting and pouring method. A formwork is erected according to a conventional constructional column formwork erecting method, one face of the formwork is reserved for erecting an inverted-triangular formwork when the formwork is erected to a lower opening at the bottom of a beam, a groove shape is formed, and the formwork is firmly fixed with nails; during pouring, concrete is firstly poured to the groove-shaped formwork and then is vibrated to be compact; then fine aggregate concrete is poured to a place being flush with the capital, a small steel chisel is inserted for vibrating, and the small steel chisel is deeply inserted by 100 mm into the lower layer of poured concrete, so that compactness of top poured concrete is ensured; and after the concrete is primarily set, inverted-triangular concrete is removed, and then the chiseling-removal portion is flattened with raw stock. By means of the capital inverted-triangular formwork erecting and pouring method, the phenomena of honeycombs and ballast surfaces at the capital of the constructional column can be effectively reduced, and concrete construction quality is guaranteed.
Description
Technical field
The present invention relates to concrete-constituted pile, particularly relate to concrete-constituted pile capital.
Background technology
In building engineering, the multilamellar in antidetonation area, high-rise frame, frame-shear structure building design in, be respectively provided with reinforced concrete structural column, this is a kind of effective measures improving filled wall and xoncrete structure shock resistance.But, work progress but there will be the quality problems such as concrete comb, pitted skin, hole, dew muscle often.These quality problems create condition to building damage in earthquake, leave accident potential.Concrete construction capital has honeycomb, pitted skin can reduce the thickness of protection tier of constructional column, strengthens carbonation depth；Hole, dew influential point of tendons subcontract constructional column cross section geometry, reduce the shear resistance of constructional column during earthquake.To be that concrete dog-house is arranged unreasonable for its main cause by analysis, brings inconvenience in feeding intake, vibrating, affects concrete formation quality.
Summary of the invention
It is contemplated that overcome the defect of prior art, it is provided that a kind of capital inverted triangle formwork and casting method.The present invention can effectively reduce the appearance of constructional column top honeycomb, pitted skin, leakage muscle, it is ensured that concrete construction quality.
In order to solve above-mentioned technical problem, a kind of capital inverted triangle formwork and casting method,
Conventionally constructional column mold method installs template, reserves one side and installs " inverted triangle " template, form groove shape, with nail by template fixation under formwork erection to beam during mouth place；
First by concreting to domatic template place, then vibration compacting when building；
Pea gravel concreten is poured into the place that capital is concordant again, plugs and pounds with little drill rod, plug and pound the degree of depth and to insert lower floor's casting concrete, it is ensured that the density that top concrete is built；
When after concrete initial set, then " inverted triangle " concrete is weeded out, then pick cutter place with oleo stock is floating.
The inverted triangle template of the present invention is smash slurry and is provided space, it is possible to effectively reduce the appearance of constructional column top honeycomb, pitted skin, it is ensured that the density that top concrete is built, it is ensured that concrete construction quality.The installation of the present invention, remove convenient, fast.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
One capital inverted triangle formwork of the present invention and casting method, for certain apartment engineering, install template including conventionally constructional column mold method, reserves one side about 300mm and installs " inverted triangle " template, form groove shape under formwork erection to beam 1 during mouth place.
1) generally, constructional column 1 sectional dimension is 200mm × 200mm, highly same floor height (being generally 3000mm), and template width during formwork is 450mm, and form height side is 2800mm, and opposite side " inverted triangle " groove depth is consistent with at the bottom of beam.
2) 2 in accompanying drawing bear down on one for Cornu Caprae seu Ovis, 3 be scaffold tubes, 4 be template, 5 be the lumps of wood, 6 be " inverted triangle " side template, 7 for " inverted triangle " bottom surface template, " inverted triangle " setting height(from bottom) suitable for reading is concordant with at the bottom of structural beams beam.
3) by the illustrated dimensions bottom surface template 7 iron nail fixation by the side template 6 of " inverted triangle " with " inverted triangle ", side template and flitch 5 being fixed with iron nail, in this master drawing, 5,6,7 will form an entirety.
4) by Fig. 1, the entire combination of left side entirety, right side template 4 and the lumps of wood 5, side template 6,7 formation is fixed complete, constructional column concreting can be carried out, but must assure that during constructional column model sheetinstallat and want firmly, to meet rigidity when casting concrete, strength and stability requirement, it is prevented that run mould, spillage.
Second step: concreting
First by concreting to domatic template place, then vibration compacting when building in this way；Pea gravel concreten is poured into the place that capital is concordant again, plugs and pounds with little drill rod, plug and pound the degree of depth and to insert lower floor casting concrete 100mm, it is ensured that the density that top concrete is built.When after concrete initial set, then " inverted triangle " concrete is weeded out, then pick cutter place with oleo stock is floating.
3rd step: column top gap plugging
30 ~ 50mm gap processing method at the bottom of constructional column top and structural beams in diagram: treat before and after concrete initial set with dry mortar (dry mortar requirement: hands is pinched agglomerating, land and bloom) clog closely knit, available little drill rod beats on surface gently with rubber hammer after plugging and pounding, guarantee density, then floating in surface pea gravel concreten oleo stock.
Such as: in apartment, Feng Ming lake, Wuhu engineering, all concrete-constituted pile all have employed triangle formwork and casting method, serves good effect, the phenomenons such as honeycomb, pitted skin, leakage muscle all do not occur at constructional column top.
Claims (1)
1. a capital inverted triangle formwork and casting method, it is characterised in that
