Tongzhou (stone hanging Company) Tongzhou District (hanging stone) Tongzhou (stone hanging Company) Tongzhou District (hanging stone) Tongzhou (stone hanging Company) Tongzhou District (hanging stone) Tongzhou (stone hanging Company) Tongzhou Area (hanging stone) Beijing Li Teng hanging stone company: granite wall hanging, has the advantage that no other exterior decoration, is the construction of a curtain wall facades technological innovation, it broke the granite used in construction projects limitations board for senior, high-rise building is granite wall decoration has opened up broad prospects. Comparison with traditional granite hanging Granite wet paste. First, the different mechanical systems: hanging Granite Hook member and each individual is directly fixed to the wall by the force can be used for high-rise building facades; granite wet paste relied reinforcement (wire) then pull the adhesive and grout, not only for the height of the building wall. Second, the wet paste method after damaging granite second quarter scorching summer and winter and cold weather brings, often leads to the plate from the shell, stripped. Third, the process of cement hydration heat and moist air easily produce granite stone wall "efflorescence", "face" and other defects. Comparison of dry hanging granite and glass curtain wall. Glass curtain wall reflection coated glass is easy to cause environmental pollution; glass curtain wall fa?ade as its poor insulation capacity; hanging Granite 石丰富 a high-level, high-rise building exterior decoration. Several issues to be tackled hanging Granite stone: first, dry hanging granite mainly rely on expanding bolt to pass power to the concrete wall, which rely on different prefabricated iron to transmit force to the traditional glass curtain wall. Second, hanging Granite stone connecting piece through a stainless steel weight transfer to the granite and concrete wall expansion bolt, stainless steel connecting plates presence deformation. Third, hanging Granite connection piece is implemented by pins, and granite material itself varies, punching their quality is the key granite stone curtain wall construction. Slab of granite stone curtain control, the first increase in problems related to stress, and secondly related to the quality of gluing. Fourth, weathering plastic sealing quality control and granite bonded with compatibility problems. Granite stone curtain wall construction of preparatory work. Granite and traditional glass curtain wall construction technique and the presence of forces of different characteristics. We should first collect all the information, and then by the Institute of Architectural Design, Construction, Urban and Rural Construction, engineering quality supervision station, supervision companies, construction units jointly organized field trips and granite stone curtain wall hanging feasibility study to reach total. Carry out the necessary work on the basis of relevant tests on: ① rely expansion bolts for hanging Granite force transmission characteristics of the stainless steel expansion Bolts were uplift, uplift capacity must be greater than the design requirements. (Typically 800kg) ② Rebound on-site concrete field testing (Shanghai dry hanging granite concrete construction specifications preliminary rating must be greater than C30). ③ pair of pins connected with the destruction of granite tests must meet when its force is greater than the design strength (500kg / m2), the granite and the pin connected. ④ mechanical testing of granite stone, its resistance to change, shear design values ??must meet the design requirements. ⑤ against distortion performance of cold-formed stainless steel angle stainless steel angle with the profile of different deformation compared. ⑥ for granite weathering plastic bonding and sealing compatibility problems, should be a special weather rubber seal 793 compatibility tests. ⑦ superimposed problems exist for the granite by force, in the construction strictly controlled to slit width, doubling every two levels stainless steel connection points at each of the force to prevent the transfer. Construction Technology 1 dry hanging marble, actinomycetes positioning: according to Level 1 noodle and stone branching diagram, each facade side and eject stone hanging prospective site elevation lines as steel keel and stone installation in vertical elevation control line . According to construction drawings and stone sub-grid map, find out the axis of each column respectively, and then determined according to the axis and window and door openings elevation line, the wall between the window edge line bomb on the wall, as the installation of steel and stone keel lateral distance control line . According stone sub-grid map and lateral control lines put away respectively emit stone ruled lines. 2, the operation of the steel keel: installing rear wall of structural steel keel may be, the concrete structure of beams, columns have embedded parts of the site, can be soldered directly connected Corner. The position may be inaccurate galvanized bolts connecting the iron fixed on the wall, and then the connection Corner welding. Brick wall shall be provided through walls bolt connection iron, as follows: steel keel arrangement according to FIG pop main steel keel vertical control line on the wall, corresponding to the vertical line of the main steel keel marked each connection corresponding positions iron plate, spacing 2 m vertical keel, keel horizontal spacing 1 m, vertical, horizontal keel spacing should be calculated and determined by the structure of the force. According hole connection iron again on the wall drill bits, masonry wall section with two bolts M12320 200 × 100 × 8 (MM) is connected by iron block is fixed on the wall, according to the provisions added set wheel. Concrete part with two M12120 galvanized iron plate bolted connections of 200 × 100 × 8, sizzling specific location see Figure arrangement design drawings. According to the main steel keel control line will connect with the welding position alignment Corner spot-on connection piece 100608-80 iron, then stand a good live steel keel (8 channel) force main part sectional thickness not less than 3.5 MM, rely on the connectors, the corresponding control line vertical alignment welding, thus completing a master of welded steel keel, the same way the vertical main steel keel entire facade is connected, fixed keel ends.
