Abstract
The utility model relates to a concrete form lining of easily regulating permeability belonging to the technical field of construction material. The utility model is used for providing the form lining which can well discharge air bubbles and excess water content and well maintain a pouring body. The utility model has the technical proposal that the utility model is formed by bonding a form frame supporting layer and a filtering layer, the form frame supporting layer is in a high molecular network structure, and the filtering layer is a synthetic fiber nonwoven. With the form lining, the air bubbles and the excess water content at the lower part of the pouring body in a form can be smoothly discharged along the filtering layer and the frame, and the separation of cement grains is prevented. When the utility model is maintained, water is added from one point so that water is homogeneously distributed on the surface of the entire pouring body, and thereby, the maintaining effect is improved, the condensation strength of concrete is increased, and the surface of the pouring body has good fineness and smoothness.
Description
Technical field
The utility model relates to a kind of concrete pouring form lining, belongs to the construction material technical field.
Background technology
In pouring concrete construction, generally adopt the method that adds release agent in the template inboard to improve stripping result at present, after the demoulding, smear plain slurry or trimming more again on the pour mass surface.There is following shortcoming in this method:
1. be unfavorable for discharging bubble.Adopt behind the cement casting vibrator with cement and reinforcing bar and and template between bubble discharge, still the bubble of its underpart can't be discharged when the pour mass height is higher, thereby brings disaster to quality, so once-cast is concrete height-limited.
2. because the existence of bubble causes the concrete pore many, and moisture content enters into inside concrete easily, make inner corrosion of steel bar, corrosion reinforcing bar volume increases, and cement is produced expansion force, reduces cement strength.
3. during the conventional template fluid concrete, excessive moisture can constantly be accumulated between template and the pour mass, and cement granules is constantly separated out, and causes pour mass wash cement too high levels, increases permeability, reduces concrete durability.
4. the conventional template fluid concrete makes the maintenance difficulty, and moisture content is difficult to evenly distribute and be retained on the integral surface of pour mass.
5. the fastness of smearing plain slurry after the demoulding again is not enough, forms two skin phenomenons easily, the fineness and the planeness on influence surface.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of form lining that can be good at discharging bubble and excessive moisture and can carry out good maintenance to pour mass.
The technical scheme that addresses the above problem is:
A kind ofly be easy to infiltrative concrete blinding liner, it is made of form cage supporting layer and filtration beds bonding, and the form cage supporting layer is the macromolecule net structure, and mesh size is 2 * 2-5 * 5m, net bone thickness is 1-3mm, and filtration beds is the synthetic fibers non-weaving cloth.
Above-mentioned concrete blinding liner, described form cage supporting layer Unit Weight is 350-550g/m
2, the Unit Weight of filtration beds is 100-300g/m
2, the flow that passes through of filtration beds is 20-80L/m
2/ S.
Above-mentioned concrete blinding liner, the mesh shape of described form cage supporting layer can be square, rhombus, circle or hexagon.
Structure of the present utility model can make the concrete blinding liner both have required permeability, has rigidity required when being attached to the template inwall again.When it is attached to inwall, the bubble and the excess water of pour mass bottom in the template is discharged smoothly along filtration beds and supporting layer, and prevent separating out of cement granules.Can make moisture content be evenly distributed to whole pour mass surface by add water at a place during maintenance, thereby improve maintenance effect, increase concrete setting strength and keep its surface good fineness and planeness.Can be easy to realize by the mesh size of adjustment supporting layer and the weight of singly answering of filtration beds to the infiltrative regulation and control of liner.In addition, the utility model in use, it is all convenient especially to attach and remove, and has also improved speed of application greatly.
Description of drawings
Fig. 1 is a structural profile schematic diagram of the present utility model;
Fig. 2 is the elevation of form cage supporting layer.
The specific embodiment
As we can see from the figure, the concrete blinding liner is made of form cage supporting layer 1 and filtration beds 2 bondings.Form cage supporting layer 1 is the macromolecule net structure, can adopt macromolecular materials such as polyvinyl chloride, polypropylene, polyethylene to make.Mesh 3 is of a size of 2 * 2 to 5 * 5mm, and net bone thickness (and the rib of mesh is wide) is 1-3m, and the shape of mesh 3 can be multiple shapes such as square, rhombus, circle, hexagon, is diamond-shaped meshes shown in the figure.Form cage supporting layer 1 Unit Weight is 350-550g/m
2Filtration beds 2 is synthetic fibers non-weaving cloth (as a nonwoven), and the Unit Weight of filtration beds 2 is 100-300g/m
2, the flow that passes through of filtration beds 2 is 20-80L/m
2/ S, these parameters have determined the density degree between non-woven fabrics fiber.
This form lining has good permeability for air and moisture content.In work progress, liner is laid on template surface, then fluid concrete.After the cast, vibration by bobbing machine, bubble in the concrete is upwards discharged, and generally is difficult for the concrete lower part of discharging and the bubble of bottom can upwards be discharged along form lining, has solved that concrete casting injection body bottom bubble is difficult for discharging and can not the too much problem of once-cast.Simultaneously form lining can also make the excessive moisture in the fluid concrete discharge along liner, can avoid the unnecessary moisture content of accumulation between template and the pour mass like this, thereby prevents that cement granules from separating out, forming excessive cement layer on the pour mass surface.The another kind effect of form lining is a curing concrete better.To pass through certain curing time after the concrete pouring, will be in curing time constantly to pour mass surface sprinkling moisture content.In traditional template construction, moisture content can not reach the whole surface of pour mass, has influenced maintenance effect.After using form lining, moisture content can arrive the whole surface of pour mass equably along liner, therefore can just can finish maintenance work in a regional water filling on pour mass surface, and is not only effective, also saves time, laborsaving.
