Abstract
A kind of template for high standard concrete Quality Control, including steel gang form, geotextiles and geomembrane.Steel gang form is provided with steam vent, and geomembrane is provided with bleed hole, and geotextiles are arranged between steel gang form and geomembrane.The bleed hole of φ 1mm is beaten on geomembrane surface, and geomembrane is booked by the spacing rectangular array of 100mm × 100mm, and geomembrane is cut by single steel gang form size.The bubble that concrete position to be poured produces in concrete placings vibrate just collects in geomembrane surface, geomembrane can will collect in the bubble on surface and cause geotextiles by the bleed hole on geomembrane and excluded through the steam vent on steel gang form in process of vibrating, not result in the situation that bubble is accumulated in steel gang form surface.Concrete surface packing can be improved using this template, stomata, honeycomb and pitted skin phenomenon that formation of concrete outward appearance occurs is solved.
Description
Technical field
The utility model is related to a kind of concrete blinding, specially a kind of mould for high standard concrete Quality Control
Plate.
Background technology
It is higher to Surface Quality of Concrete requirement at present with the development of concreting technology, due to by former material
The restriction of material, match ratio, template and the factor such as vibrate, pours formation of concrete face and substantial amounts of deleterious bubbles often occurs, reduces
Surface Quality of Concrete and durable performance.
Two river mouth Hydropower station pivotal water retaining structures are gravelly soil core wall rockfill dam, crest elevation 2875.00m, riverbed portion
Position core-wall bottom elevation 2581.00m, substrate sets 1m thickness concrete pedestals, maximum height of dam 295.00m, width at dam crest 16.00m, left and right
Bank cover plate concrete is according to the different slope ratios respectively 1 for pouring elevation:09,1:1.1 and 1:1.3.Core-wall cover plate concreting
The quality of quality, directly influences the antiseepage level of whole dam, so the requirement of cover plate concrete construction quality is high.The engineering
Main and designing unit requires that the surface defect such as honeycomb, pitted skin and hole etc. that occur for cover plate concrete need to be according to design requirements
Strict treatment is carried out using epoxy mortar.
Two river mouths power station selection watt Zhigou building stones T3lh1(2)Aggregate material source, lithology is rotten siltstone folder powder
Sandy slate, sandstone aggregate quality is not high, and flat-elongated particles are excessive etc., and factor is one of bubble Producing reason.Simultaneously using normal
The common steel form advantage of rule is difficult deformation, it is easy to which assembled, surface is smooth, but has the disadvantage that unnecessary moisture can not be absorbed, no
The exclusion of bubble during beneficial to concrete vibrating；Left and right banks cover plate concrete topping reinforcing bar comparatively dense, operation difficulty of vibrating is larger, together
When left and right banks cover plate concrete use placement in layers, concrete is constantly closely knit when layering is vibrated, inside concrete excessive gas
Vibrated floating is excluded vertically upward in the form of bubble, increased the distance of removal of bubbles for heeling condition because of template, works as gas
When bubble floats up to template surface, the obstruction of template can be subject to and directly can not be excluded vertically upward, these bubbles will be attached to mould
In plate surface, after just foring substantial amounts of stomata, honeycomb and pitted skin phenomenon in concrete surface after concrete formation.
Utility model content
The utility model provides a kind of template for high standard concrete Quality Control, solves formation of concrete outward appearance
There is stomata, honeycomb and pitted skin phenomenon, concrete surface packing can be improved.
In order to solve the above technical problems, the technical scheme that is used of the utility model for：
A kind of template for high standard concrete Quality Control, including steel gang form and be pasted onto on steel gang form
Geomembrane；The steel gang form is provided with steam vent, and geomembrane is provided with bleed hole.
According to such scheme, geotextiles are provided between described steel gang form and geomembrane.
According to such scheme, the bleed bore dia on the geomembrane is 1mm, by the spacing rectangle battle array of 100mm × 100mm
Row are booked geomembrane.
Compared with prior art, the beneficial effects of the utility model are:
The access issues in bubble ejectment removing template face produced during slope concrete pouring can be effectively solved, is shortened
Bubble floating vibrate until excluding the time outside template, bubble can quickly be excluded by the exhaust passage of template, effectively
Reduction interior formwork generation, the problems such as reduce slope concrete outward appearance honeycomb, pitted skin and hole, improve concrete
Dense surface degree, it is ensured that Surface Quality of Concrete meets design specification requirement.
Brief description of the drawings
The template for high standard concrete Quality Control a kind of to the utility model is made furtherly below in conjunction with the accompanying drawings
It is bright, wherein：
Fig. 1 is the front view of the composition schematic diagram of single template；
Fig. 2 is the top view of the composition schematic diagram of single template；
Fig. 3 is the mounting arrangements schematic diagram of template.
Each label is interpreted as in figure：1- steel gang forms, 2- geotextiles, 3- geomembranes, 4- steam vents, 5- bubbles, 6-
Concrete to be poured.
Specific embodiment
A kind of template for high standard concrete Quality Control, including steel gang form 1, geotextiles 2 and geomembrane 3.
A collection of steel gang form 1 to newly marching into the arena drills, uniform on every piece of steel gang form 1 using the bit bore of φ 2cm
3 φ 2cm steam vents 4 of ground auger.The specification of the steel gang form 1 for using for：1500mm long, 300mm wide, thick 50mm.Drill
Bi Hou, grinding process is carried out to the surface of steel gang form 1, uses clean gauze wiped clean, it is ensured that the cleannes on surface.
The bleed hole of φ 1mm is beaten on the surface of geomembrane 3, and geomembrane 3 is booked by the spacing rectangular array of 100mm × 100mm, and geomembrane 3 is pressed
The single size of steel gang form 1 is cut.XY-401 adhesive is uniformly applied to the table of steel gang form 1 using hairbrush
, then be attached on steel gang form 1 successively for geotextiles 2 and geomembrane 3 by face, is flattened using Steel Ruler, has prevented fold and drum
Bag situation, geomembrane 3 is sturdy with the surface of steel gang form 1, it is ensured that geomembrane 3 is firmly bonded reliability.By the soil of lacing wire bar hole position
Work film 3 cuts open, and facilitates lacing wire bar to install, with tamper-proof geomembrane 3.It is equal to the surface of geomembrane 3 after geomembrane 3 is bonded and finished
Even brushing CJ type releasing agents.During installation form, note protecting geomembrane 3, prevent breakage.In concreting process, note shaking
Tamper can not touch geomembrane 3, damaged geomembrane 3.After the completion of form removal, the template to removing is cleaned, it is ensured that template
Can reuse.
The utility model biggest advantage is that an exhaust passage, gas are formd between steel gang form 1 and concrete
Bubble 5 once touches geomembrane 3, that is, be rejected to outside template.The geotextiles 2 for being used are hydrophilic material, in geomembrane 3
It is upper to beat bleed hole, the effect of ejectment bubble is played, geotextiles 2 can will be accumulated in the bubble warp on the surface of geomembrane 3 in concrete
Bleed hole is drawn, and the steam vent 4 in combined template is excluded, while will not lose substantial amounts of cement grout again.Using geomembrane 3
Smoothness of the surface, in its surface smear CJ type releasing agents, it is ensured that the repetition of the glossiness and template on formation of concrete surface
Usability.
