Description
Technical field
The present invention relates to the making and the mounting method of door body structure, be specifically related to a kind of heavy opposite opened fan-shaped gate fabrication and installation technology.
Background technology
Existing heavy fan-shaped gate, because volume is big, weight tonnage is big, causes difficulty of construction very big, installation accuracy is low, and the engineering time is long, inefficiency.Wherein the welding assembling process of the interior lining panel of fan-shaped gate adopts butt welding at present, but because area is big, the length of assembly unit weld seam long (the wall scroll weld seam reaches 7m), therefore the thinner thickness (1cm) of interior lining panel, easily produces gross distortion (as shown in Figure 1) during welding simultaneously, and, adopt artificial two-sided butt welding, labour intensity is big, and welding quality is difficult to guarantee.Especially after the monolithic interior lining panel is finished single-sided welding, interior lining panel must be sling, turn-over, weld seam back chipping, polishing, after reaching requirement, carry out the reverse side welding again, technology is numerous and diverse, and poor stability, easily causes previous weld cracking.
Summary of the invention
The present invention is in order to overcome the deficiency that above prior art exists, and a kind of fabrication and installation processing quality, heavy opposite opened fan-shaped gate fabrication and installation technology that installation accuracy is high of improving is provided.
Purpose of the present invention realizes by following technical scheme: this heavy type is characterized in that: may further comprise the steps form fan-shaped gate fabrication and installation technology:
(1), makes working platform;
(2), the alignment material, require to carry out cutting stock according to design size;
(3), assembly unit welding interior lining panel, weld the top angle on bent limit, the top angle of longitudinal edge, following lower edge angle steel at the edge of interior lining panel, at vertical channel-section steel of the interior welds of interior lining panel and reinforcing rib, the jockey pulley of assembly unit truss and truss;
(4), at the lower end of lower edge angle steel welding joist, at the lower end of joist assembling main wheel;
(5), lifting interior lining panel and truss, between interior lining panel and truss, assemble exterior sheathing;
(6), fluid concrete between interior lining panel and exterior sheathing;
(7), after the concrete setting, the dismounting exterior sheathing carries out derusting by sandblasting and sprays paint truss, fan-shaped gate is electrically connected open-close on-off, just finishes fabrication and installation of fanning fan-shaped gate;
(8), according to another fan fan-shaped gate of above-mentioned seven step fabrication and installation.
As a kind of optimization, the material of described joist is cast steel ZG270-500.
As a kind of optimization, the material of described top angle, lower edge angle steel is angle steel Q235.
As a kind of optimization, described interior lining panel adopts automatic submerged arc welding single face welding and double face shaping technology: in advance with the rightabout location of workpiece by distortion, be put on the liner, reversible deformation angle a is 5 °～10 °, and in cushion block, put welding agent, do flame correction after welding is finished, obtain the plane of designing requirement behind the welding deformation.
As a kind of optimization, described open-close on-off is the far infrared rays optoelectronic switch.
The present invention has following advantage with respect to prior art:
One, this heavy opposite opened fan-shaped gate fabrication and installation technology, the quality of raising fabrication and installation technology in each step, the installation accuracy height is increased work efficiency.
Two, interior lining panel adopts automatic submerged arc welding single face welding and double face shaping technology, has proposed " reversible deformation " technology, reduces distortion, and planeness is reduced to 5mm by 50mm, and improves work efficiency 30%." reversible deformation " technology in advance with the rightabout location of workpiece by distortion, promptly navigates to the plane of designing requirement behind the welding deformation.In order to guarantee that the actual effect after default reversible deformation and welding deformation are offset adheres to specification, determine that through test of many times default reversible deformation angle a is generally 5 °～10 °, does flame correction after welding is finished and gets final product.
Three, open-close on-off adopts the far infrared rays optoelectronic switch, has effectively improved the keying quality of fan-shaped gate, for long-term the use provides assurance.
