The following provisions shall be in the installation and disposal of the basic level:
The embedded design elevation, position and quantity shall be in accordance with design and installation requirements, and the anticorrosion treatment. When the buried parts do not comply with the requirements, the timely and effective measures shall be taken to supplement the buried parts.
The installation of stairs railings vertical rod part, concrete base not Susong phenomenon, and the installation elevation shall comply with the design requirements, the rugged department must be eliminated or repair of flat, serious recesses and grassroots cellular pits, shall not be repaired with cement mortar, application of high strength concrete repair, and to be a certain strength, railings installation.
2, according to the design and installation requirements of the bar to install the correct pop-up spacing position and center line.
3, stainless steel staircase railing, arm installation operation key points:
The railing pole should be installed according to the requirements and construction of line from the start up sequence. The starting platform of the stairs should be first installed, the installation of the welding and bolt fixed two methods.
Welding construction, the welding rod should be the same with the parent material, when the vertical rod and the embedded parts spot welding temporary fixed, after elevation, vertical correction, welding and firm.
The bolt connection, the vertical bar at the bottom of the metal plate hole should be processed into waist round hole, to prepare for expansion bolt position does not match, the installation can make small adjustments. Construction, installation pole base site in, use electric drill for drilling into the expansion bolt, connected with the vertical rod and a fixed, installation elevation error with a metal shim adjustment, the vertical, standard college after locking nut.
Both ends of the pole after the installation of the same method, the other pole mounted with a pull line. The installation of the vertical rod must be firm, and the. Vertical rod welding and bolt connection parts, except for stainless steel, after the installation, should be anti-corrosion and rust treatment, and can not expose, should be installed in the root of the decorative cover or cover.
The impregnated with organic glass, glass board, the board should be installed on the pole after the completion. The installation must be firm, and the vertical, horizontal and gradient shall be in accordance with the design requirements. When installed, the tailgate is inlaid in both sides of vertical rod groove in, the groove and the tailgate on both sides of the gap hard rubber strip embedded firmly, until after the handrails installed, with sealant block. Rail welding installation, the tailgate used asbestos cloth covering protection, so as to avoid welding spark splash damage tailgate.
The stair handrail installation, general welding installation (except for special size). The material of the welding rod shall be the same as the base material.. The installation sequence of the arm should start with the starting elbow, then connect the arm to the rail.. Handrail interface to a desired angle sets of cutter is correct, and metal file file, in order to avoid a cut is not accurate, causing handrail bending and difficult installation. When the installation, the starting point of the elbow and rail rod spot welding and fixed, pending inspection no false welding firm. After the installation of the elbow, straight rail ends with the two ends of the vertical rod temporary fixed spot, also will straight arm end the head butt and a fixed spot, an interface should 2-3mm of welding seam, and then pull line the armrest and each root pole as a fixed spot, to be inspected in accordance with the requirements, according to welding requirements, the interface and a handrail and rod by welding firm. Welding (especially during winter construction), should master welding current, voltage and welding temperature, in order to prevent excessive current or excessive or excessive voltage instability, welding quality and beauty. The welding quality should accord with the relevant regulations, the width and depth of the weld should be consistent, the surface should be the fish scale, the welded seam of the arm joint should be tight, and the welding seam should be no obvious deviation..
The longer the metal handrails, especially outdoor handrail after installation, the joint should be considered installation can adapt to temperature changes telescopic movable interface, quantity of expansion and contraction of the movable joints, such as the design requirements generally consider 20mm. The outdoor arm should be considered in the retractable place to set the leakage hole. The connections between the root of the arm and the concrete and the brick wall should be generally used as a flexible fixation method so as not to deform the rails due to stretching.. The handrail and wall connecting root should install decorative coverCatalog printing
