Crown doors and windows assembly system technical requirements
【Selection and design of doors and windows】
1、After a careful review of engineering drawings, in accordance with the requirements of the drawing of the sample, determine the type and number of required windows, combined with the local wind pressure, hole size, floor level and other factors that determine the choice of reinforcing steel liner thickness.
2、Based on the measurements to calculate the hole cutting optimization, including profiles of glass, hardware, steel-lined reinforced, tops and other auxiliary accessories selected requisition made under the Comprehensive Optimization.
【Profile cutting, milling drainage hole, keyhole】
1、Master double angle sawing profile material cutting, material left at each end 2.5mm - 3mm melting capacity to do welding, cutting error should be controlled within 1mm, deviation angle controlled within 0.5 degrees.
2、To frame profile milling of drainage holes, fan profiles generally milled drainage holes and pressure balance hole, requiring drainage hole diameter 4-5mm, length 30mm, steel-lined drainage holes can not be set in the cavity, it can not penetrate the steel-lined chamber.
3、If you are installing power transmission and lock the door, according to the appropriate position size milling keyhole.
【Reinforcing steel liner assembly】
1、When the door member size equal to or greater than a predetermined length, the cavity must be added to enhance the steel liner.
2、Hardware-assembly of the doors and windows and splice combinations must be added to enhance steel liner.
3、Reinforcing steel liner assembly should not affect the welding site, first inserted and fixed, fixed steel liner fasteners each not less than 3, the distance is not more than 300mm, from the steel liner end is not greater than 100mm.
4、Cross-shaped and T-joints of steel liner, the profile molten weld plate just mention, just at the beginning of the docking insert, to be fixed after welding.
【Welding clearance angle】
1、Welding welding temperature control is intended to depression in 240 ℃ - 250 ℃, feed pressure 0.3 - 0.35Mpa, clamping pressure 0.4-0.6Mpa, melting time 20--30 seconds, cooling time of 25 - 30 Sec.
2、Qing Qing angle corner points manual and mechanical clearance angle, welding is completed 10 minutes after the start of clearance angle, try to complete the clearance angle within 30 minutes after welding.
Fan, fan tops yarn assembly according to different specifications, can not exceed the length of the bar tops, profiles should be shorter than 3-6mm, so as not to affect the quality of welding.
Plastic doors and windows box finished by assembling the fan is made of metal pieces. Hardware assembly principle is: have sufficient strength, the right place, meet the functional and easy to replace. Hardware should be fixed on the inserted steel liner, hardware fixed can not use ordinary wood screws should be used & Phi; 4mm self tapping screws, hardware location but also in strict accordance with standards.
To install the glass into the glass part of the first pad, will cut a good glass on the pad, and then through the glass fixed glass bead clamp.
Section Rao En doors and windows assembly system technical requirements
1、Doors and windows should be reserved for the hole installation method, construction method can not be installed after the side edge of the puzzle port or install build ports, size window and door openings should be consistent with national standards, "Building Regulations size window and door openings."( GB5824)。
|Hole size(mm)||Less than2400||2400-4800||2400-4800|
Note: The powder has good hole
2、The main tools: hammer, hand drill, & ldquo; ten & rdquo; word screwdriver, & ldquo; a & rdquo; word screwdriver, hammer, bakelite hammer, drill, wedges, etc. to dial. The main measuring stick: horizontal and vertical meter, hanging wire hammer, tape measure, angle, ruler, etc. Other: helmets, safety belts, the word ladder, rope and so on.
3、Doors and windows placed in a clean, flat place, avoid the sun and rain, not in contact with corrosive substances, doors and windows can not be in direct contact with the ground, the lower should be placed chocks or other soft material, put side by side, stand up angle greater than 70 degrees, and should be anti-dumping measures to be taken. Door Storage ambient temperature should be less than 50 degrees, the heat source is not less than 1 m, the doors and windows should not be placed over two months at the installation site.
4、When handling and transport of windows and doors, should be handled with care, non-skid, throw, throw, drag. When lifting the doors and windows, non-metallic surface application of soft liner materials.
5、Check the hole, drawing, finished doors and windows of the three dimensions are equal, check varieties, specifications, and assembly opening direction, attachments, and their shape and flatness correction, check whether the doors and windows whipped bad, the hardware is complete and intact, was found should make up the protective film off, and then start the installation.
【Doors and windows and installation process】
1、The windows and doors of different sizes corresponding to the hole transport upright and looking up and down the center line on the doors and windows box, make a mark, multi-storey building should be placed perpendicular
2、When installing, pay attention to the orientation of the window, up and down, fixed frame and sash pulleys, etc. is not installed, if fixed on the window glass has been installed, you should remove the glass, and mark.
3、The window frame is loaded hole, line it up and down the box with the hole centerline alignment, determined according to the design window frame and the wall thickness in the hole position to install and adjust the vertical, horizontal and vertical angle of the window frame, in line with its tolerance Claim.
4、Installation of doors should be carried out before the ground construction, according to the opening direction and the doors and windows of the drawing to determine the door installed, and measures should be taken to prevent the deformation of the door frame, lower frame swing should be no two lower corners of the border line below ground level to about 30mm , taken off the box flat open sliding door and the frame, so that the next frame should be below ground level line of about 10mm, and adjust the level of the door frame, vertical and angle.
5、Expansion bolt, position fixing plate mounted to the corners from 150 - 200mm place, the distance should be no more than 600mm, rear window and the window mosaic, with self-tapping screws from both sides to tighten the screw pitch of 600mm, from both sides of the 200mm. Adjust the horizontal and vertical, the window frame or door frame and the wall, fixed connection.
6、Completion inspection fixed horizontal, vertical position after passing the seam and the upper door frame and the wall around joints filled with mineral wool, expanded polystyrene and other flexible materials, and the wedge plate removed after filling its voids also filled, fan windows and doors to be adjusted, the frame and the wall below the gap to fill, fill in when the sealant should be uniform uninterrupted, smooth and no cracks.
