Prefabricated flower decoration installation process

Prefabricated floral installation


1 Scope
    The process standards for general civil engineering and high-level public buildings indoor and outdoor prefabricated floral installation works.
2 construction preparation
    2.1 Materials and products:
    2.1.1 prefabricated ornamental products: a wooden flower erosion, cement mortar floral, concrete floral, terrazzo floral, metal floral, plastic floral, gypsum floral, soil burning products floral, stone relief decoration. Its variety, specifications, design selection by design.
    2.1.2 according to the design of the floral varieties, to determine the installation of fixed way, the choice of appropriate installation materials, such as adhesives, bolts and screws of the species, specifications, welding materials, affixed paste materials and fixed methods.
    2.2 The main equipment:
    2.2.1 electric tools: electric welding machine, hand motor
    2.2.2 Equipment and tools: pre-fight platform, special fixtures, spreader, scaffolding, the size of barrels, scraper, scraper, paint brush, water brush, board, rubber hammer, cloth and so on.
    2.3 Operating conditions:
    2.3.1 installation of floral decoration of the room and parts of its road project, must be completed, should have the strength of the substrate, the grass-roots level must meet the requirements of the installation of floral.
    2.3.2 installation of floral fixation, generally paste method, wood screw fixation, bolt fixation, welding fixation; heavy floral position should be embedded in the construction of the anchor structure.
    2.3.3 floral products approach or self-processing should be checked by inspection, material, plans should meet the design requirements. Cement, gypsum products should meet the strength of the design requirements, and meet the hardness, stiffness requirements of the standard.
3 operating process
    3.1 Process flow:
Grass-roots processing → determine the installation location line → block flower decoration pre-spell number → installation methods and processes

    3.2 Primary treatment: floral decoration should be installed before the substrate or grass-roots clean, scrub clean, deal with the formation, and check whether the base to meet the requirements of installation floral.
    3.3 to determine the location of floral installation line: according to the design position of a good floral position center line and block the control line. Heavy-duty flanges should check whether the embedded parts and the solid bricks are in conformity with the design requirements.
    3.4 block flower decoration pre-spell number: block flower decoration in the formal installation, deal with specifications. Color testing and selection, according to design patterns on the platform group fight, the number of pre-qualified for the formal installation of the conditions for the plan.
    3.5 Installation method and process:
    3.5.1 Floral paste method Installation: General light floral use paste method to install. Adhesive material according to the variety of floral materials selection.
    3.5.1.1 Cement mortar floral and cement water brush stone decoration, the use of cement mortar or polymer cement mortar paste.
    3.5.1.2 gypsum flower decoration is appropriate plaster or cement paste paste.
    3.5.1.3 wooden floral and plastic floral adhesive can be used to paste, can also be used nail solid method.
    3.5.1.4 metal flower decoration should use screws, according to the structure of optional welding installation.
    3.5.1.5 prefabricated concrete flower or floating surface decoration products, the application of 1: 2 cement mortar masonry, blocks of steel pin with each other between solid and solid structure with the connection.
    3.5.2 Screw-mounting method: Heavy-duty large-size ornaments are fixed with screws. When the installation will floral alignment holes embedded in the structure of embedded fixed, with copper or galvanized screw appropriate tighten, floral pattern should be an exact match, fixed with 1: 1 cement mortar after the installation hole blocking Yan, the surface with the same floral color Of the material modification, leaving no trace.
    3.5.3 Bolt fixed installation; weight, large-scale floral installation using bolt method. When the installation will floral alignment hole at the installation location of the embedded bolts, according to the design requirements of grass and floral surface of the gap size, with nuts or pad plate fixed, and temporary support. Floral pattern should be accurate, the stitch anastomosis. Floral and wall gap on both sides and the bottom of the temporary block with gypsum, to be gypsum after solidification, with 1: 2 cement mortar layered into the gap between the floral and wall, from bottom to top each irrigation about 100mm height , The lower end of the final condensate after a layer of Hong Kong. Grouting mortar to reach the strength to remove the support after the removal of temporary sealing around the plaster, modified by integrity.
    3.5.4 Welding and fixing method Installation: Heavy-duty metal flower decoration is fixed by welding. According to the design and construction, using the method of temporary solid hanging, according to the design requirements to find the first position, the welding point should be uniform, welding quality should meet the design and the relevant specification requirements.
4 quality standards
    4.1 Warranty items:
    4.1.1 Variety, specification, pattern and installation method of floral ornaments must meet the design requirements.
    4.1.2 floral installation must be strong, no loosening, cracks, warping and missing flutter angle and other defects.
    4.2 Basic Items:
    4.2.1 the installation of floral grass and floral surface should be clean.
    4.2.2 installation joints closely match, consistent tone, in line with design requirements.
    4.3 Permissible deviation items, see Table 9-54.
5 protection of finished products
    5.1 floral installation of the lower plate closed after the application to prevent bumps.
    5.2 Floral application After installation, the cover is closed for cleanliness and color tone.

                              Permissible deviations for floral installation Table 9-54
Frequency
Allowable deviation (mm) Inspection method
Indoor and outdoor
1 level of the degree of floral and vertical meters per meter and the amount of wire drawing board check
Total length of 3 6 and the amount of wire drawing board check
2 separate floral centerline position offset 10 15 vertical and horizontal pull line and the amount of inspection

    5.3 dismantling the child or moving materials, equipment and construction tools, may not touch the damaged floral, pay attention to the integrity of protection.
6 should pay attention to quality problems
    6.1 Floral fall off: Floral installation must choose the appropriate fixation method and paste material. Attention to the variety of adhesives, performance, to prevent the stick is not strong, resulting in open sticky off.
    6.2 Floral installation of the straight over-bias: Note the precise line and block the degree of splicing.
    6.3 Floral distortion, cracking: screws and bolts fixed floral not hard twist, so that the average point of each force, to prevent distortion and distortion of floral.
    6.4 Floral dirty: floral installation to strengthen the protection measures to maintain a good floral intact clean.
7 Quality records
    This process standard shall have the following quality records:
    7.1 Floral products certification and product acceptance information.
    7.2 adhesive selection of test data.
    7.3 installation of quality assessment information.
