The glass curtain wall installation specification details |
Wan Yee feed Qingdao glass curtain wall experts in the many years of professional production of glass, steel doors and windows vocational career, my technical department signed a detailed glass curtain wall installation specifications, statement of this specification applies to the general civil cabinet glass curtain wall installation works (of which the main load-bearing skeleton of the form of longitudinal and transverse keel intermediate structures embedded in the glass curtain wall keel), and other buildings just do recommend to use, does not mean that the installation of standard procedures:
The requirements of the glass curtain wall materials
(1) fasting aluminum keel and level keel: You must have factory certification and inspection records, under the direct supervision of the machining accuracy and surface finish, no warping, no scratches, in order to meet the design requirements.
(2) Glass: general color (for example: brown, black, blue) light, hollow glass and single non-lighting glass, inspection and acceptance method. The glass must have factory certification and test records, surface coatings (single or dual side of the glass coated with a metal film) is not allowed to scratch on and off, stored in metal boxes or special scaffolding.
(3) rubber products, rubber mats with: basic certificate, and must have the correct size of the aging test certificate, meet the design requirements, free from cracks and breakage.
(4) aluminum trim layered color is consistent, no deformation, damage,
(5) Main keel connection fastening pieces of iron and the main keel and keel fittings: inside and outside the casing (or connection), galvanized to meet the design requirements of materials and specifications for size. When the secret storage area.
(6) bolts, nuts, nails, stainless steel, the certificate of origin approach, unpacking, and sampling.
(7) sealing materials: factory certification, bonding and water, and must meet the design requirements.
(8) the thermal conductivity and thickness of fire insulation materials to meet design requirements.
All of the above materials, all need to be properly stored sub-standard, not rain exposure and other harsh environmental conditions.
2 curtain wall installation of major equipment
The large group: tower crane, topical elevator, electric basket, electric vacuum suction cups (glass suction device).
Small groups: the jaw manually sucker (carrying a glass tool), welding nail gun, electric screwdriver, pistol drill, wrench, adjustable wrench, theodolite (or laser theodolite), the level of steel tape, iron horizontal ruler, steel ruler Steel Square welding machine.
Installation of curtain wall and operating conditions
(1) the main structure of concrete has been completed, and complete quality inspection and acceptance procedure.
(2) completed before the measurement.
1) Select any level has the release of the theodolite (or laser theodolite), vertical and horizontal lines, to set the axis layer. Pop-up the vertical centerline of the main keel at the same time check whether the centerline of the embedded parts of the main keel centerline to match the floor edge. The same size and curtain wall between the main keel between the size of the measurement.
2) According to the horizontal axis, to determine the iron buried layer outside the main keel and tighten the cable fastening iron, convenient installation.
3) to verify the structure and design of the actual total elevation elevation and marked on the side of the ground floor elevation layer to check the installation.
(3) connected to the main keel embedded tick the hammer before the iron, such as altitude exceeds the allowable deviation of the elastic line position, the exposed concrete surface must be designed to negotiations.
(4) installation of electric (or shelf) layered safety glass and safety for the operators decorative basket, the basket after the installation of safety devices running test.
(5), suction equipment, hand drill, stud welding, motor to do the insulation test. Electric suction machine and hand-held glass suction cup, check the weight of the adsorbed glass and adsorption time and the instructions provided.
(6) the main keel, keel, decorative layering, bolts, tape, pre-inventory classification code designated locations, set the desired link supervision store.
The operation of the process to install the glass curtain wall
The following procedure to install the glass curtain wall
Each floor installation fastening iron → anyway keel assembly → → → install vertical main keel to install galvanized steel → install insulation, fireproof mineral wool → security → security cover, double glazing and decorative layered → install floor closed, the installation lateral keel of galvanized steel plate → Cleaning the glass
5 quality standards
(1) to ensure that the following items:
1) aluminum alloy keel, specifications, sectional dimension of the material must meet the design requirements and related standards, accompanied by a certificate of origin.
2) the production quality of primary and secondary keel and accessories to meet the requirements of the design drawings and related standards, the factory certification and product acceptance certificate.
3) All aluminum parts are installed in fixed, its location and connection method must meet the design requirements.
4) single and double glass cutting dimensions are correct installation and smooth, solid, no loose.
(2) basic items:
1) the surface of aluminum alloy components clean, no scratches, bumps, no rust.
2) All exposed metal parts, from any point of view, should be a smooth surface, smooth vertical and horizontal, it should be no deformation. Screws and components are closely linked, the surface may not have the bump.
3) glass color, pattern meet the design requirements, the surface is clean, no stains, install the right direction.
4) sealed tight mosaic glass formation of the sealant to seal uniform, smooth surface, no glue marks.
(3) Tolerance project are shown in Table 4-27.
Table 4-27
Project to allow deviation (mm) test method
A vertical deviation of the vertical keel 3.5 m length, hanging line check
Two keel horizontal level deviation of 3.5 m length of the scope, level or ruler to check
The total length of measuring tape
3 keel surface roughness of 33 m straightedge and feeler gauge the amount of any party
4 raise the water level or tape measure to check
6. Product protection
(1) Aluminum alloy frame materials and various accessories, into sub-specifications, a dedicated studio-rain classification code shall not place heavy objects on the pressure on the transport of materials, gently, to prevent damage to scratch. Sub-specifications of glass standing on the wooden poles, set up the distribution and transport of the supervision to prevent break something and scratch the surface coating.
(2) outside the cable car to the designated person in charge of temporary fixed floor to stay on the floor to prevent the basket collision keel keel. Safety glass, steel basket pad foam pad end, called the day before the basket pull, rather than on the floor, to prevent crashing into the glass, safety glass.
(3) The glass curtain wall installation is complete, a certain distance in order to prevent away from the glass curtain wall on the floor, hanging safety nets, and sent a patrol to a nearby
(4) process in the glass curtain wall in front of the construction work on the glass near the temporary protection fiber plate.
Should be noted that quality problems
(A) glass is not installed: Install the vertical centerline of the vertical transverse keel is not double-check does not check the glass size, must strictly control the vertical centerline of the vertical installation, the level of the keel.
(2) decorative vertical to horizontal: the installation of decorative pressure bar suspension wire, pull the level of control, security, and the horizontal level, vertical stratification.
(3) Glass serious "image distortion" phenomenon causes: the glass itself, warpage, uneven rubber install the glass coating of contaminated clay. The practice of the glass out of the box to check warpage should be no pre-installed resection. Wipe clean after the installation process, the process is strictly operating mosaic plane sealant surface.
(4) surface contamination of the aluminum alloy components: mainly in the transportation and installation process, the early spread of the surface protection film, or the surface of the plastic pollution.
(5) seepage of the glass curtain wall: the rubber glass around the impaction lax or interface stormwater infiltration into the gap caused by the winter the water may freeze expansion caused by a single glass squeeze crush, so the security tape to match the specifications of size not is too large or too small to form a dense wedge-shaped, the interface must be sealant filled solid to achieve watertight shall prevail. Running test of the line safety equipment.
(5), suction equipment, hand drill, stud welding, motor to do the insulation test. Electric suction machine and hand-held glass suction cup, check the weight of the adsorbed glass and adsorption time and the instructions provided.
(6) the main keel, keel, decorative layering, bolts, tape, pre-inventory classification code designated locations, set the desired link supervision store.
Specifications to install glass walls, everyone must strictly abide by, without the slightest careless neglect, contempt for a small part, may lead to the cause of the entire project, glass curtain wall perfectly - a qualified installation technology, and strict materials to complete the program, Qingdao glass manufacturer Wanzhi, I think you are a beautiful life.
