Outer wall heat preservation nail balance and adjustment effect in the thermal insulation engineering
thermal insulation on the insulation decorative role to play in balance and regulating function of
bar for outdoor and indoor decoration has become the construction industry is one of the indispensable parts, although its size is not big but it can not dismiss! Today HeJian heat preservation nail factory professional and technical personnel for you detailed introduce heat preservation nail in thermal insulation decoration system of balance and regulating function:
one, the owner often, according to acceptance by the traditional effect of curtain wall system if the installation of flatness slightly worse, will appear the appearance of the obvious quality defects. Especially in heat preservation decoration construction scaffolding, due to the large Angle is limited, at the same time combined with film on the surface of the composite board, it is often difficult to find workers uneven between plate and plate. A lot of engineering is to wait until after engineering scaffold removed, only to find that the appearance defect of metope, then it is too late, the anchoring and stick-on composite insulation board not adjusted. Therefore, some reference to the installation of curtain wall insulation manufacturer method, adjust the fitting is used to adjust ( A similar small keel) Adjust the fittings selection principle and installation technology requirements:
1, the outer wall heat preservation nail galvanized leveling fitting selection principle:
all site leveling fitting to avoid corrosion must make all must be installed using galvanized leveling fitting.
a, when the project batch specification plate area is greater than the total area of 60%, and the single board area is greater than 2. More than 5 square with 20-30 * * 1. 5 square tube as leveling fitting at the grass-roots level.
b, when the project covers an area of more than 60% of its total bulk specifications board, and the single boards is greater than 2 square more than 20-30 * * 1. 2 square tube as leveling fitting at the grass-roots level.
c, as the project covers an area of more than 60% of its total bulk specifications board, and the single boards is less than 2 square below using 20-30 * * 1 square tube as leveling fitting at the grass-roots level.
d, all auxiliary materials must also be corrosion resistant function, the product must be in line with national standards, certification and detect file formal inspection reports, and other products.
two leveling fittings, insulation nails, installed and fixed technical requirements:
a, galvanized fittings fixed cross direction should be installed according to the scene situation, namely the keel need to adopt welding processing.
b, leveling fitting and leveling fitting spacing is not greater than 1200 mm, when leveling fitting distance is greater than 1200 mm must increase the leveling fitting, the back of this increase leveling fitting in the mounting plates must increase bonding material to bond the plate in order to increase the fastness. For a single piece of plate area is less than 0. 5 ㎡, can not use paste mortar increase; For a single piece of plate area is greater than zero. 5 ㎡, must use paste, mortar, and paste area must be greater than 10% of the surface area. Paste way can use article point sticking method and the viscosity method.
c, for a single piece of panel size is less than 300 mm (on all sides can be fixed on both sides of the symmetrical, when two parallel edges on both sides of the size of parallel side panel is more than 300 mm, the other two parallel edges less than 300 mm edge can be fixed more than 300 mm, two parallel edges when the panel size is greater than the fixed around 300 mm must be used.
d, leveling fitting scheme must conform to the drawings design requirements, at the same time must conform to the national standards and related standards.
1, the vertical and horizontal leveling fitting leveling fitting welding processing should be adopted for the connection. Without fixed before using spot welding connection, after adjust full welding strengthen connection must be used.
2, must first be butt welds in leveling fitting it cleaned up and butt anticorrosive processing it. Specific can use red lead antirust paint; Zinc coat; Rusty coat three antirust processing, etc.
3, in leveling fitting welding after the fixed, single block surface area must be greater than zero. More than 5 square panel, the leveling fitting and metope to block the use of lightweight insulation mortar filled, in order to increase wind pressure strength. For single block board face small area 0. 5 -
4, square sheet or unilateral size less than 300 mm steel plate leveling fitting is not filling processing at the local level.
5, leveling fitting with a fixed point spacing of metope is not greater than 600 mm, must add protection when greater than 600 mm. The distance protection to the endpoint is not greater than 300 mm.
6, leveling fittings installed on the concrete wall ( Single heat preservation nail tensile strength 1 kn) : when using heat preservation nail fixed, spacing in a 500 mm - 600毫米; Using metal anchor pieces, spacing can keep mm - in 600 - - - - - - - - - - - - 800MM。 ( See the appended drawings: concrete protection) 。
7, leveling fittings installed on the hollow bricks ( Single heat preservation nail tensile strength 2. 2 kn) : when using heat preservation nail fixed, pitch control in the 600 - mm - - - - - - - - - - - - 800MM。
8, leveling fittings installed on mortar and block ( Single heat preservation nail tensile strength of 0. 5 kn) : when using heat preservation nail fixed, pitch control in the 300 - mm - - - - - - - - - - - - 400MM。
