3.1 Job Instruction for Installation of Sandwich Panels

3.1.1 Scope of application

The Job Instruction has been developed for the complex of works on installation of wall enclosures from light metal panels of "sandwich" type.

External wall panels perform not only enclosing, but also aesthetic functions for the erected building.

Works performed in series during panel installation include:

- marking of panels installation places;

- installation of panels on support surfaces;

- alignment and fixation of panels in design position.

The works should be performed in accordance with the requirements of the following regulatory documents:

SP 48.13330.2019 Construction organization. [4]

SP 70.13330.2012 Bearing and enclosing structures [5]

SP 49.13330.2012. Labor safety in construction. Part 1. General requirements [6]

SNiP 12042002. Labor safety in construction. Part 2. Construction production [7].

3.1.2. Organization and procedure of works execution

In accordance with SNiP SP 48.13330.2019 "Organization of Construction Production" before the start of construction and installation (including preparatory) work at the facility, the General Contractor is obliged to obtain permission from the Customer to perform installation work in accordance with the established procedure. The basis for the start of work may be the Certificate of technical readiness of the structures of the building framework for the installation of panels. As-built geodetic diagrams are attached to the acceptance certificate with application of columns position in plan and height [4].

Acceptance of the object for installation shall be carried out by employees of the installation organization.

Installation of panels is carried out in accordance with the requirements of SNiP, Working Design, Work Design and instructions of wall panel manufacturers. Replacement of panels and materials provided for by the project is allowed only in agreement with the design organization and the customer.

External wall panels are installed in a separate mounting flow after installation of the frame and coating of the entire building or part of it on the wall section within the limits of the temperature seam. Panels of external walls are accepted with length of 6 and 7.2 m at height of 1.0 m.

The following works shall be completed by the general contractor prior to installation of the panels:

- quality of panels, their dimensions and location of embedded parts were checked;

- exact breakdown of panel installation places in longitudinal and transverse directions, as well as by height;

- hairlines are applied, position of vertical seams and panel planes is determined. Hairlines are applied with a pencil or marker;

- installation horizon is fixed on each floor of the building;

- temporary access roads for vehicles are arranged and platforms for storage of panels and crane operation are prepared;

- panels are transported and stored in cassettes within the crane mounting area;

- metal fasteners, as well as necessary mounting facilities, accessories and tools are delivered to the installation area.

Panels are unloaded and stored vertically in cassettes. The cassettes shall contain the number of panels required to be mounted between the two columns over the entire height of the building. The cassettes are placed so that the crane from the installation parking can set them in the design position without changing the boom departure (see Figure 3.2) [8].

3.1.3 Quality control and acceptance of works

3.1. Monitoring and evaluation of the quality of work during panel installation is carried out in accordance with the requirements of regulatory documents:

SP 48.13330.2019 Construction organization [4].

SP 70.13330.2012 Bearing and enclosing structures [5].

GOST 26433.294. Rules for measurement of parameters of buildings and structures [8].

3.2. In order to ensure the necessary quality of panels installation, assembly works shall be subject to inspection at all stages of their execution. Production control is divided into input, operation (process), inspection and acceptance. Quality control of the performed works shall be carried out by specialists or special services equipped with technical means ensuring the necessary reliability and completeness of control, and shall be assigned to the head of the production unit (foreman, foreman) performing installation works [8].

3.3. The panels coming to the site shall meet the requirements of the relevant standards, their fabrication specifications and working drawings.

Prior to installation works, panels, connectors, fittings and fasteners delivered to the object shall be subject to input inspection. The quantity of products and materials to be inspected shall comply with the specifications and standards.

Incoming control is carried out to identify deviations from these requirements. Incoming control of the incoming panels is carried out by external inspection and by checking their main geometric dimensions, presence of embedded parts, absence of damage to the front surface of the panels. It is also necessary to ensure that non-concrete steel embedded parts have a protective anti-corrosion coating. Embedded parts, mounting loops and slinging holes shall be cleaned of concrete. Each article shall be marked with indelible paint [8].

Panels, connectors, as well as fasteners delivered to the object must have an accompanying document (passport), which indicates the name of the structure, its brand, mass, date of manufacture. Passport is a document confirming compliance of structures with working drawings, valid GOST or TS [8].

The results of incoming control shall be drawn up by the Act and entered in the Log of incoming control of materials and structures.

3.4. During installation, operational quality control shall be carried out. This will make it possible to identify defects in a timely manner and take measures to eliminate and prevent them. Control is carried out under the supervision of the foreman, foreman in accordance with the Operational Quality Control Scheme. It is not allowed to use non-design linings to align the mounted elements by elevations without coordination with the design organization.

During operational (process) control, it is necessary to check compliance of the main production operations for installation with the requirements established by construction codes and regulations, working design and regulatory documents.

Pre-assembly of walls from light panels into cards must be performed on stands in the area of the main installation crane. Limit deviations of "maps" dimensions during pre-assembly are indicated in the WP. In the absence of special instructions, the limit deviations of the dimensions of the "cards" should not exceed ± 6 mm in length and width, the difference in size of the diagonals - 15 mm.

Results of operational control shall be recorded in the Log of Works on Installation of Building Structures [8].

3.5. Upon completion of panels installation, acceptance control of works performed is performed, at which the following documentation is presented to the inspectors [8]:

log of works on installation of building structures;

acts of examination of hidden works;

certificates of intermediate acceptance of mounted panels;

actuating diagrams of instrumentation check of mounted panels;

documents on quality control of welded joints;

passports on the panel.

3.6. During inspection, the quality of installation work shall be checked selectively at the discretion of the customer or the general contractor in order to verify the effectiveness of the previous production control. This type of inspection can be carried out at any stage of installation works [8].

3.7. The results of quality control carried out by the customer's technical supervision, author's supervision, inspection control and comments of persons supervising the production and quality of work shall be entered in the Log of works on installation of building structures (the Recommended form is given in Appendix 1 *, SNiP 3.03.0187) and recorded also in the General work log (the Recommended form is given in Appendix 1 *, SNiP 3.01.0185 *). All acceptance documentation shall comply with the requirements of SNiP 3.01.0185 * [8].

3.8. The quality of works execution is ensured by fulfillment of the requirements for compliance with the necessary technological sequence when performing interconnected works and technical control over the progress of works set out in the Construction Organization Project and the Work Execution Project, as well as in the Work Operational Quality Control Scheme.

Installation quality control is carried out from the moment the structures arrive at the construction site and is completed at commissioning of the facility [8].

Conclusion

At the end of my report, I want to say that during the practice for 4 weeks, at the Engineering and Technology Institute of Abakan, Republic of Khakassia. According to the individual assignment of the GSiH department, I developed a process plan for the installation of sandwich panels. This is justified by the fact that in the course project on the discipline "Architecture of Civil and Industrial Buildings," I designed a "closed-type ground mechanized parking lot" on this topic, I plan to fulfill the VKR. In this regard, the teacher S.A. Ivanyuk asked me and decided to develop those maps for the installation of sandwich panels in my building. I would also like to see Ivanyuk as the head of the VKR. S.A.

There were no particular difficulties in the course of production technological practice. During the practice, he studied technical documentation, worked in the programs AutoCAD, Word, and also compiled a report on practice.

Not enough of this practice is that it went remotely and could not see the entire technological process in the living.

The advantages of this practice are that the student independently had to find solutions to fulfill his tasks. That it is not doubtful to be useful in life and professional activity.
