The present invention provides a super long span total glass steel deodorizing cover plate, which is made of high strength glass steel supported by no metal skeleton. Its characteristic is that the cross section of the cover plate is a large span arch, and the longitudinal section is a continuous small span arch. The cover plate is connected by a number of cover plates. Each cover plate unit is located in two. The 2.5 arch side wing of the side, the depression part between the 2.5 arched flanks form a pedestrian passage, and the lateral end of the 2.5 arch flanks is respectively set up the connecting flange, the connecting flange is located on the top of the semi arch flanks, and the two adjacent flanges are connected by the connecting flange, and the flange after the connection is formed to form a position. Longitudinal stiffeners on the outside of the cover plate. The cover plate unit connection of the cover plate of the invention is located at the top of each small span arch. After the flange is connected to the flange, a longitudinal reinforcement is formed at the flange side of the cover plate. At the same time, the longitudinal strength of the cover plate is strengthened, and the span of the cover plate is promoted.

一种超大跨度全玻璃钢除臭盖板及臭气收集装置
本专利技术涉及臭气收集
,具体涉及一种无骨架大跨度低净空除臭盖板及臭气收集装置。
技术介绍
目前,传统的臭气收集装置一般采用反吊纤维膜、加钢管骨架的玻璃钢单拱板、内衬不锈钢架的卡普隆板等,存在诸多弊端;例如:反吊纤维膜需做支撑钢架,其重量较大,部分已建污水池无法承受其重量,净空高,除臭风量大,人在内部工作,环境恶劣,且容易形成收集死角;内部包裹钢管的玻璃钢盖板容易在日夜温差下发生开裂,寿命短;内衬不锈钢架长期在除臭罩内,暴露在臭气浓度高的环境中,其不锈钢构件会发生腐蚀。现有技术1中国专利技术专利申请CN201510902487.7公开了一种臭气收集装置的玻璃钢盖板,如图5-6所示,其横截面(B-B截面)为一个大跨度的拱形形状,其纵截面(A-A截面)为若干连续的拱形,,以形成一个双向拱形结构,所述玻璃钢盖板是由两块大跨度拱形玻璃钢盖板除臭罩6连接而成,且两块玻璃钢盖板的连接面7为平面,盖板内壁具有加强筋8。该现有技术存在如下缺陷:1、虽然盖板强度高,上部可上人操作检修,但是为了保持强度,盖板是由两个较大的,纵截面为若干个一体的连续拱形组件连接而成,要加工并运输如此巨大的组件是很不易的。2、两块盖板连接处为平面,破坏了双拱形整体承力结构,限制了跨度的进一步扩大。现有技术2中国技术专利CN200720106288.6公开了一种用于污水处理厂的玻璃钢盖板,如图7-10所示,其主体9的纵向呈大圆弧形,横向呈小圆弧形,主体的内壁设有若干垂直交错的纵向加强筋11和横向加强筋10。所述主体的纵向两侧面向上翻起各形成一侧面立 ...
