玻璃钢桥架的主要制作成分是不饱和聚酯树脂、环氧树脂、玻离纤维无捻粗纱、玻璃纤维毡、连续玻璃纤维纱。下面山东桥架厂家来讲讲玻璃钢电缆桥架的成型工艺与厚度规范事项:
The main manufacturing components of GRP bridge are unsaturated polyester resin, epoxy resin, glass fiber untwisted roving, glass fiber felt, and continuous glass fiber yarn. Next, Shandong bridge manufacturer will talk about the molding process and thickness specification of GRP cable bridge:
玻璃钢桥架成型工艺有:
The forming process of FRP bridge includes:
拉挤成型玻璃钢桥架、模压成型玻璃钢桥架、复合成型玻璃钢桥架、手糊成型玻璃钢桥架。
Pultrusion glass fiber reinforced plastic bridge, molding glass fiber reinforced plastic bridge, composite glass fiber reinforced plastic bridge, hand lay-up glass fiber reinforced plastic bridge.
它具有强度高、绝缘性能好、重量轻、结构合理、寿命长、施工简单、配线灵活等特点,同时具有优良的耐化学腐蚀,耐火、阻燃性强和足够的机械强度。广泛适用于石油、化工、冶金、电工等部门电缆铺设场所。
It has high strength, good insulation performance, light weight, reasonable structure, long service life, simple construction, flexible wiring and other characteristics, and has excellent chemical corrosion resistance, fire resistance, flame resistance and sufficient mechanical strength. It is widely used in cable laying places in petroleum, chemical, metallurgical, electrical and other departments.
玻璃钢电缆桥架的厚度规范如下:
The thickness specification of GRP cable tray is as follows:
当玻璃钢电缆桥架宽度小于150mm时的玻璃钢制桥架的板材小厚度应达到3.0mm
When the width of fiberglass cable tray is less than 150mm, the small thickness of fiberglass cable tray plate shall reach 3.0mm
150mm宽~300mm宽的玻璃钢桥架的板材小厚度应达到3.5mm
The small thickness of the plate of 150 mm wide~300 mm wide GRP cable tray shall reach 3.5 mm
300mm宽~500mm宽的玻璃钢桥架的板材小厚度应达到4.0mm
The small thickness of the plate of the glass fiber reinforced plastic bridge with the width of 300mm~500mm shall reach 4.0mm
500mm宽~800mm宽的玻璃钢桥架的板材小厚度应达到4.5mm
The small thickness of the plate of the glass fiber reinforced plastic bridge with the width of 500mm~800mm should reach 4.5mm
当玻璃钢桥架宽度大于时800mm宽时的玻璃钢桥架的小板材厚度应达到5.0mm
When the width of the fiberglass cable tray is greater than 800mm, the thickness of the small plate of the fiberglass cable tray shall reach 5.0mm
山东桥架
注:它的连接板的厚度少按托盘、梯架的侧板厚度等厚度选用,也可以选厚一个等级。盖板的厚度可以按托盘﹑梯架的厚度选低一个等级。宽度W≥400的玻璃钢电缆桥架,底部厚度允许低于托盘、梯架侧板厚度,但必须加横挡,横档中心距不应大于400mm。采用特别结构形式桥架,各部位厚度允许低于本表,但是载荷〈SWL)需要满足《玻璃钢电缆桥架NB/T10287—2019》4.3.1处的标准。
Note: The thickness of its connecting plate shall be selected at least according to the thickness of the side plate of the tray and ladder, or one grade of thickness can be selected. The thickness of the cover plate can be selected as a lower level according to the thickness of the tray and ladder. For GRP cable tray with width W ≥ 400, the bottom thickness is allowed to be lower than the thickness of tray and ladder side plate, but the cross bar must be added, and the center distance of the cross bar should not be greater than 400mm. The special structure type bridge is adopted, and the thickness of each part is allowed to be lower than that in this table, but the safety load (SWL) needs to meet the standard in 4.3.1 of Fiberglass Reinforced Plastic Cable Bridge NB/T10287-2019.
