Abstract

The invention discloses a safety reinforcing device for road and bridge cracks, which is characterized in that the top end of a mounting support plate is connected with a fixing bolt, the top end of the mounting support plate is connected with a limiting support block, the side end of a connecting cable is sleeved with a U-shaped limiting box, the top end of the U-shaped limiting box is connected with a clamping screw rod, and the side end of the clamping screw rod is connected with a clamping plate; the top end of the rotating supporting frame is connected with an I-shaped limiting block, a connecting cable penetrates through a limiting fixing hole and is finally clamped to the inner side of the I-shaped limiting block and the side end of a limiting linkage plate, the I-shaped limiting block drives the connecting cable to be stretched and tightened, and rapid adjustment and limiting are facilitated; according to the gap limiting and fixing device, the two ends of the gap can be clamped and fixed when the gap needs to be limited and fixed, the clamping and clamping plate and the U-shaped limiting box are driven by the clamping and clamping screw to be matched to clamp and limit the connecting cable, the tightness of the connecting cable can be continuously adjusted in the using process, and continuous maintenance by workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of road bridge reinforcement, in particular to a safety reinforcement device for cracks in road bridges. Background technique [0002] Bridge reinforcement generally refers to restoring or improving the bearing capacity of existing bridges by reinforcing components and improving structural performance, so as to prolong their service life and meet the requirements of modern transportation. The general procedure of bridge reinforcement is: investigate and determine the technical The purpose, requirements and technical standards of the renovation, check the status quo and damage of the bridge, investigate the historical technical data of the bridge and the existing traffic conditions, draw up maintenance and reinforcement or reconstruction plans and analyze and compare them, determine the plans and put them into practice and complete the project after the reinforcement is completed acceptance. [0003] However...
