Proper removal of the formwork or "break - not to build ," will not go !

Starting Date

Removing formwork assembly is done in reverse order.In order during this process not to break the parts of the construction already during mounting must consider how you will remove it.Gvozdeva connections are disconnected, the board or plywood separated from the concrete.Sometimes boards are inserted between the individual thin narrow pieces of plywood to form a place to catch and remove the formwork.

shoot it is possible only after the concrete has become sufficiently strong.Only in this case, the concrete will not be damage the load that it receives during removal.Drying time the mixture, depending on the brand, can reach 28 days.However, if the air temperature is below 5 degrees Celsius, the drying time will be doubled.If during removal of the sub-zero temperatures, then this process should wait until the frost has passed.

Important!The final decision on removal of the structure, making sure that the concrete is well grasped.

formwork Removing

formwork Dismantling must be carried out by separate elements, smoothly, without jolting and gently to avoid breaking the concrete and construction.In this connection, to work with an ax or sledgehammer is strictly prohibited.Construction of large span dismantled raskruzhalivaniem gradual, that is the first thing a little upsetting all the wedges, and only after that the full withdrawal begins.

The formwork first drop load-bearing structures. This process can be simplified by using the rack to lower the head. sharp fighting off the design elements is prohibited.To release the large-area panels are used mechanical devices, such as threaded bolts, which are mounted on the design boards.You rotate the bolts, and the board away from the base, make it easier than dismantling.

Important!Dismantling of the formwork must be carried out in compliance with all safety standards.

If there is a column, wall or console, then they must first remove the formwork.And only after that you can disassemble the structure with beams, lintels and ceilings.To avoid cracks and depressions in the liberated slabs, placed auxiliary rack (if the width between the spans of more than eight meters).If spans of up to eight meters, is enough for them to put one supporting beam in the middle.

Cleaning and storing design

After dismantling the whole formwork is cleaned of residual concrete, wood and other dirt.This should be done carefully, for example, the water pressure as manual cleaning can seriously damage components.Use concrete plane only for non-planed boards and panels.Hand tools, such as a grinder or rotating brush, and can only be used for items with improved surface.

all boards must be carefully stored in one place when dismantling the formwork foundation.It is necessary to check that there were no protruding nails or other protruding elements.This is especially important for lacquered plywood, since the damaged layer of varnish its protective properties greatly reduced, and the material quickly deteriorates.After cleaning all the elements if you plan their further use, they must be dry and lubricate with engine oil.Storing all the elements needed to dry the excess moisture place.

Note!If formwork elements will be kept on the street, then they should be put vertically to minimize their contact with the ground.
