Lighthouse slats are made of thick planks of 4-6 cm and a width equal to the height of concreted prepare and attach to the base of wooden pegs, were killed on the minimum depth of 30 cm distance between the pegs should be no more than 1.5 m. The Lighthouse strips can be applied to inventory mnogooborachivaemye metal structures, such as channel bars. Learn more about this with Microsoft CMO. The required project grade concrete training plan provides a base or by the underlying layer, in which case the upper or lower bound of the lighthouse board cut the ramp. During the concreting of training the individual sections should produce ready-made wood or metal inventory of Lighthouse formwork. Combining the elements of shuttering must be reliable and provide a quick and easy assembly and disassembly of the formwork at the site of its installation. After concreting the surface of a clean concrete floor will be overwritten by trowel.
For small volumes of concreting preparations recommended carry out this process in the simplest scheme. Concrete Delivery Truck Dump Truck or in this case can call in to upload a mixture of outside concreted lane or drive up the side and unloaded a lighthouse mix board. Mixer can drive up to Beacon board and unload the mixture on the concreted strip across the tray. The scheme of concreting preparations under floors with concrete pumps, equipped with articulated boom, is not fundamentally different from scheme of concreting with a self-propelled conveyor paver. If you use concrete pumps for the device monolithic concrete preparations preferably provide: – a continuous concreting – rhythmic pump providing a concrete mixture that eliminates time wasted on cleaning and preparation of Delivery line of the pump to work – lack of long breaks in the supply of concrete – the preparation of the front work, allowing used concrete pump is most effective – control the consistency of concrete mix and concrete quality. When designing concrete preparations using concrete pumps must take into account that the pumps are designed for pumping concrete mixes with slump 6-8 cm, while preparations for the under floor mobility lay concrete mixture should be 0-1 cm in pumped concrete mix should be elevated in the sand dust and small particles. All this leads to increased consumption of cement and water content. The decrease in water content and cement consumption while maintaining the required mobility of the mixture can be achieved through the use of plasticizers.
