Formwork in construction

For under pouring planking that can be a different form is required. The type of soil and even climatic features of the region influence on her choice. But it is necessary to know what it after good and what exist to his variety.

Determination of planking

Planking is a building form that can be permanent or temporal and determines the type of future building of monolithic type. It is therefore clear, planking is for what required. 

Main destiny of this good is giving of project configuration liquid concrete mixture. Planking can be different kinds, application of any kind straight depends on configuration of the built construction, used materials and features of climate.

Frequently a опалубочная construction is a form of collapsible type, gathering on building site from different materials. The prepared forms, assembling of that comes true in the prepared construction, as elements of designer, are used on occasion already. Main functional of planking:

• giving building from the concrete of project configurations;
• maintenance of the set sizes;
• maintenance of necessary position is in the space of the poured off monolith.

Planking is used sometimes with the purpose of giving of the poured off surface of certain relief. Requirements that is produced to the similar construction, used in building:

• durability - forms must maintain loading that appears concrete mixture;
• firmness to deformations - the collected building must not disperse or bend after the inundation of solution from cement;
• firmness to the aggressive environments - the surface of forms must not be subject to corrosion in case of contact with a moist surface;
• impermeability - forms must not assume the losses of concrete solution;
• availability - the form work systems must be collected from inexpensive and accessible materials.

Types of planking on materials of making

For creation of planking it is necessary to use such materials:

• boards;
• purveyance from a metal;
• reinforced concrete;
• expanded polystyrene.

Most expensive variant metal. Foliar from steel, the thickness of that makes a 1 mm minimum, are used, they without fail are set in case of creation of foundation of band and monolithic type. If you may need, then it is necessary to create the construction of any configuration. In case of requirement in the increase of inflexibility of material from that founding is produced, then it is necessary to weld on an armature to the metallic foliar.

Second, no less expensive variant – production of the reinforce-concrete planking. For her forming use already the prepared folios from a concrete. Due to this method there is creation of reliable construction, diminishing here the expense of solution from a concrete. To take up setting, building special equipment is needed. 

If one flag it will be not enough, then it may need to use additional materials and cross-bars. The cost of works will be megascopic in this case.

Also, the practical enough and quality construction erected from пенополистирола, for creation of that blocks are used. There are no complications at editing, but however at creation of corners and скруглений, it is required preliminary to prepare blocks and adhere to instruction.

In the case when there are facilities strongly not enough, it is necessary to use the wooden planking. For her creation apply standard boards or plywood, standing inexpensively. With the purpose of creation of construction it is enough to apply only one building instrument for realization of joiner works. But because of that a similar construction requires to be additionally strengthened, expenses can as a result far increase.

Types of planking on the method of application and their destiny

There are such varieties of planking :

• removable;
• unremovable;
• sliding.

An Unremovable construction it is better to use, when it is impossible to produce dismantling during a great while. Also, with his help an additional functional can be created. 

A removable type is frequently used in the field of building. This building that consists of aluminum alloy and other metals shields. It is connecting elements between bars. Useful to monolithic building, as at a necessity then it is possible to smuggle out of or leave inwardly. Befit for frequent exploitation. The use of removable type is actual in the cases when building of a few building projects is prearranged, or foundation must be inundated on large territory. The use of the leased planking is popular, allowing to save considerable part of budget to building organizations. Inexpensive material is mainly used: ruberoid, metallic folios. More often all of it is not dragged out from a construction. 

A sliding kind must be examined in the separate order. The use is expedient not only in monolithic foundation but also at erection of walls.

Varieties of planking on the types of the concreted constructions and their destiny

Planking is classified on the functional setting taking into account the type of the concreted constructions. In these cases distinguish planking:

• for the receipt of vertical surfaces (including walls); 
• for horizontal and sloping surfaces; 
• for formation of curvilinear surfaces (for example, pneumatic); 
• for the simultaneous concreting of walls and ceiling, rooms and whole apartments.

Planking for concreting of walls is produced such kinds: small-shield and large-board lifting-resettable, block forms, block, sliding. 

For concreting of ceiling use a demountable-resettable construction with supporting elements, large-board, where form work surfaces and supporting elements are incorporated in the panel wholly moved by a faucet.

For the simultaneous concreting of walls and ceiling or part of building apply the by volume of-resettable planking.

Horizontally moved, in the number of that rolling planking, (use for concreting of vertical, horizontal and sloping surfaces, and also for the simultaneous concreting of walls and ceiling).

Types of planking for constructions and their destiny

Taking into account a construction to distinguish a few variants of equipment. The question is about:

• stationary removable planking - gathers from boards and squared beams. Application of this variant of equipment is conditioned by complication of forms or their non-standardness. Use a similar construction once, after hardening of concrete, forms take apart and send material in wastes or use for other needs;
• demountable or reset table planking consisting of separate shields or baskets of different size. From them collect forms for founding of columns, foundations and other details. After hardening of concrete mixture of form take apart and move into other place for the repeated application. Such type of planking is most widespread and highly sought. This type of equipment is used with the purpose of erection of different constructions from the reinforced concrete, except towers, reservoirs and another structures with the rounded outlines;
• for creation of constructions on height of planking of suspended-type is used. Her difference is in application of bars on that the shields of planking are laid;
• the movable or sliding planking is used with the purpose of building of high objects. This equipment as far as concreting rises wholly, without sorting out. Skidding is guaranteed due to the use of the special jacks.

Movable or the катучие systems as far as piling of concrete move horizontally. For this purpose use the specially laid rails.
