Construction of continuous footing has the features. Filling bases rather simple. At the initial stage necessary calculations for power and depth of laying of the foundation, and only are carried out then start the main preparatory work and direct mounting of timbering, prefabricated reinforcement cage.
It is required to you
- - tes;
- - crushed stone;
- - sand;
- - gravel;
- - armature;
- - wire for knitting;
- - cement.
Instruction
1. The load level on future base is the main secret which is surely considered. All calculations come down to that the base was rather powerful, but at the same time the sum of final construction has not increased to the maximum mark. And the lack of power of the basis will lead to fast destruction of the built building therefore it is necessary to ask specialists in design for the help with carrying out calculations or to use special formulas.
2. Level of freezing of the soil in your region and depth of underground waters – key parameters at direct determination of depth of the base. Your foundation has to be laid so that it was not waterlogged by underground waters and at the same time that concrete has not collapsed when freezing.
3. The main preparation for construction of the base consists in number of works. At first carry out marking, dig hole under ditch, strengthen internal layer of earth, establish timbering, build in prefabricated reinforcement cage. Filling is final stage of all preparatory process.
4. Establish timbering taking into account that it should be removed after filling of the base. Now on sale there are elements of removable timbering. Also they can be taken in short-term rent.
5. You remember, the prefabricated reinforcement cage is important element of the base. It is mounted in the established timbering taking into account the bearing loading. Direct mounting is carried out by welding method, and sheaves by means of special lashing wire.
6. At direct filling of the base consider, the quality of concrete has to conform to certain standards. Cement of brand 400 and quality crushed stone of crushed fines is suitable for heavy construction.
7. Time of full hardening of solution corresponds to 28 days. Through this period it is possible to begin direct construction. But already at once after installation of continuous footing it is worth taking care of socle laying. Then to wait the specified time and to begin wall construction.
