Logging Guidelines
1. In the table of the journal, the designation of efforts is adopted:
N nk - controlled tension in the beam
N lane - the greatest (increased) tension force
N zapr - force in the bundle at which the anchor body is pressed
N p - design tensile force in the beam
The "F" index indicates the actual tension in the bundle
2. With the same values \u200b\u200bfor the value of N nk and N p in the table, efforts are put down with their indices.
3. In the table, each bundle is marked with an individual number; the position of the beam should be reflected on the executive diagram attached to the magazine.
4. Entries in the journal are made in the sequence corresponding to the procedure for the production of works on tension and installation of beams.
5. Records of the tension of the rejected beams are saved with the mark "rejected", the record of the tension of the beams installed instead of the rejected ones is made on a free row of the table in the sequence of work with the addition of the sign "instead".
6. The number of broken wires is put down with the index "about", for example, 2 about; the number of wires with slippage is entered without an index.

Formwork installation certificate - a document confirming that the form and specifications the structures comply with the requirements of the design documentation. The consequence of insufficient strength, rigidity and tightness of the formwork system is poor-quality concreting and related problems. Therefore, when conducting installation works it is necessary to strictly observe the instructions of the designers and the SNiP III-15-76 standards.
Assembly features
According to SNiP, formwork can be assembled from the following materials:
- tree;
- metal;
- reinforced concrete;
- plastic;
- inflatable rubberized fabric.
The composition of many designs involves the use of several materials. The main elements of formwork systems are shields, with the help of which they set the desired shape of the object to be concreted. Most often, installation is carried out directly at the construction site. It is also common to use solid blocks, which, after pouring concrete, are transferred to another place using lifting equipment.
Regardless of how the SNiP formwork device is carried out, the correctness of the assembly is checked at all stages. Deviations from the design values \u200b\u200bare permissible, but they should not exceed the dimensions specified in technical documentation and standards III-15-76. For control are used measuring instruments and geodetic instruments. The reliability of the fasteners, the tightness of the joints, and the general stability of the structure are checked without fail. If at some stage of the SNiP installation of the formwork displacement or deformation is noticed, all work is stopped until the malfunction is completely eliminated. In addition to the main structure, responsible persons must control the installation of auxiliary equipment - scaffolding, scaffolding, etc.
Stripping
After the formwork acceptance certificate monolithic structures signed, start concreting the object. We will talk about how to fill in the mixture correctly next time. Let's go straight to the moment when it is necessary to start dismantling the system (if it is not a disposable equipment remaining in the concrete). First of all, the side elements are removed, which do not carry a serious load. This can be done when the strength is reached, at which deformation of surfaces and corners is excluded.
The main bearing shields are removed later. The concrete mix must harden at least 70% of the design value. This is sufficient when it comes to slabs, beams and girders with a span of less than 6 m. In the case of larger objects, the SNiP formwork provides for a strength of 80%. In areas of increased seismic activity, the parameters are determined on an individual basis. The timing of stripping is determined by a special laboratory, based on the results of the analysis of concrete samples.
Delivery of the object
The SNiP formwork act will not be of particular importance if the object to be concreted does not pass the control check of the state commission. During this procedure, the surfaces are examined and the main geometric indicators are measured. If the representatives of the commission have doubts, additional laboratory tests are assigned.
During the acceptance process, check:
- the strength of concrete, as well as its water resistance and frost resistance, if required;
- the quality of the materials used according to the certificates, passports and test results attached to them;
- the presence of the required amount of reinforcement and the correctness of its placement (this information may be contained in the act for the formwork);
- compliance with the configuration of the object specified in the project (holes, openings and other elements are recalculated and measured);
- surface quality and correct seams.
A well-assembled formwork that meets all the instructions of the designers is an almost one hundred percent guarantee that there will be no problems with the object. Poor quality of the mixture and ignoring the requirements of technology can interfere with high-quality concreting, but that's another matter. At least the geometry will be respected. Our company in Moscow offers its services for the rental and installation of formwork systems for various purposes.
