The Three Main Points Of Bailey Panel Reinforcement Preparation And Construction: Price, Manufacturer, And Quality

      Bailey panel price The goal of Bailey Bridge reinforcement is to repair, reinforce, improve the bearing capacity, and strengthen the utilization function through reinforcement construction. Therefore, the selection of the reinforcement plan should take the improvement of the quality of the reinforcement project as the basic goal. There are also different construction preparation and quality assessment scales for different reinforcement schemes. According to several typical reinforcement arrangements in the "Specifications for Concrete Layout and Reinforcement Techniques" and following the construction experience, the inconsistent reinforcement arrangements should be implemented during construction:

　　1. External bonding steel reinforcement method for concrete members

The construction of this method is relatively simple, but at first it is necessary to focus on the general treatment of concrete and steel plate. The bonding surface of the old and dirty concrete components should be cleaned to dust, and then acetone can be used to wipe the general situation; the general treatment of steel plate should be According to its embroidering environment, it can be polished with sandblasting, emery cloth, and grinder to make the steel plate appear metallic, and the polished texture is as perpendicular as possible to the target of the force target, and then wiped clean with acetone. Secondly, we must look forward to the choice of adhesives. At present, the domestic market construction layout adhesives are thick and cloudy, and the choice of adhesives must be cautious. Thirdly, we must look forward to the details of the glue dispensing and pasting process. The adhesive must be prepared in strict accordance with the proportion required by the declaration. In particular, the amount of curing agent must be controlled, the mixing must be even, and the fullness of the pasting surface must be guaranteed when pasting. , Dense. It is hoped that no disturbance to the steel plate can be made during the curing stage.

　　2. prestressed reinforcement method

When pre-stressed tie rods are used for reinforcement, the tie rods need to be straightened before installation. The dimensions and installation position of the tie rods must be accurate. The quality of welded joints, screws and nuts should be inspected before tensioning. It is hoped that the quality inspection of the embedded depth force transmission weld between the angle steel (and its backing plate) and the concrete member at the end of the brace. After the inspection is passed, the two ends of the brace are temporarily fixed with bolts, and then epoxy mortar Or high-strength cement mortar for filling and grouting, and the reinforced strut limbs, connecting plates, affixed plates and tension bolts, etc. should be coated with anti-rust paint for anti-corrosion.

　　 3. External steel reinforcement method

For the Bailey Bridge, the general treatment, including the condensed connection surface and the steel plate bonding surface, should be taken as the key to the reinforcement construction process. For dry reinforcement construction, in order to make the angle steel close to the member profile, the concrete profile needs to be polished and smoothed. , No debris and dust; when adopting wet reinforcement construction, the prepared angle steel and concrete should be smeared with latex grout or epoxy resin chemical grouting, and the steel plate should be derusted, and the concrete should be dust-removed with acetone or Xylene cleans the steel plate and concrete profile, glues and pours.
