Abstract

The invention relates to a steel plate fixing device and a fixing method for steel plate bonding construction. A steel plate is provided with a hole through which an anti-degumming bolt of a reinforcing component passes; the upper surface of the steel plate is provided with an anti-degumming washer and an anti-degumming nut; a lower nut, a lower washer, section steel, an upper washer, an elastic washer and an upper nut are arranged on the anti-degumming bolt in turn; and a woody wedge is arranged between the steel plate and the section steel. The fixing method comprises the following steps ofcoating the lower surface of the steel plate with steel bonding structural adhesive, installing the steel plate, the anti-degumming washer, the anti-degumming nut, the lower nut, the lower washer andthe like on the anti-degumming bolt in turn, wedging the steel plate and the section steel, channel steel or angle steel by use of the woody wedge, screwing the upper nut and compressing the elastic washer. The method utilizes the anti-degumming bolt needed for bonding the steel plate, adopts a coating method to bond the steel plate, can construct under the circumstances of continuously opening traffic and having vibration, and has the advantages of short construction period, fast progress and little influence on society. The invention was used in a project of maintaining the second Changjiang River Bridge in Wuhan and got good effects.

Description

technical field [0001] The invention relates to a steel plate fixing device and a fixing method for sticking steel plate construction. Background technique [0002] Steel roads, highways, and municipal bridges need to be repaired and reinforced after being used for a period of time. In the case of continuous traffic and vibration, when using the method of pasting steel plates to repair and reinforce bridges, the relative displacement between the steel plate and the reinforced member must be limited. The structural glue used for pasting can be cured in a stable environment, so as to ensure that the steel plate and the reinforced member form a whole, and jointly bear the force to achieve the purpose of reinforcement. [0003] The paste steel plate reinforcement method is widely used in bridge maintenance and reinforcement projects because of its small footprint, no reduction in bridge clearance, and the flexibility to set the reinforcement location and scope according to desig...
