The arrangement of the formwork on uneven surfaces the idea is not easy and entails certain difficulties. First, it is imperative to carry out a geodesic survey of the construction site for the correct calculation and design of the base of the object. With its help you will be able to identify the degree of slant of the site and geological engineering, determining the composition of the soil which you have to work. We strongly recommend not to miss this point of view, even though it will entail certain financial costs.
Engineering Foundation of the future building, you should pay special attention to the fact that the higher the level of the surface elevation, the harder it will be a set of existing work in assembling the formwork and the more reliable it will need to be strengthened. When placing formwork on uneven areas, it is necessary to strictly follow the building codes and technology. When the construction of such foundations, special attention is paid to the preparatory activities and extra.
I want to draw your attention to some important points that will help you to reduce the risks of unpredictable situations in the future.
First of all, you need a competent project of the Foundation for the construction of the object on uneven ground. It must be included: the size of the base, the intended weight load of the building on the Foundation provided by the specific pressure on the soil at different points, temporary loads.
Great importance will have a hydrogeological assessment of the site allotted for the construction and analysis of soils. It is often do the work of drilling exploration wells.
You will need to create an effective drainage system, as it accumulated moisture can eventually lead to slip-and even the collapse of the soil in the mountainous part.
Formwork erecting under the current elevation changes on the site, should be at the lowest point higher than the top. This is due to the fact that she has to withstand the horizontal level of the poured Foundation. Also, special attention should be paid to the choice of fasteners and tightening the casing elements. Since erected on uneven terrain formwork to yield greater stress than shuttering mounted on a flat surface, the elements of its attachment must be durable and reliable to fix it. We suggest in this case to use spring clips or Ciresi, as they are able to withstand loads up to 4 tons, and also completely eliminate the bias of rebar that will save you from the risk of distortion of the casing and as a consequence pour the Foundation. They are absolutely easy to install, just hook them on the valve with the outer sides of the formwork and clamp with the aid of special clamping key.
Ciros reinforced spring clip on the valve, takes the load of 3 tons.
The key to the spring clip with reinforced mechanism for greater durability, designed for tension reinforcement in the fastening of shuttering boards by means of a spring clip.
The pressure switch is intended for tensioning of reinforcement when attaching the shuttering boards by means of a spring clip Chiros.
