Steel structure manufacturer installs steel reinforcement operation for building

Steel structure installation of steel reinforcement, also known as steel plate reinforcement, is the steel plate with high performance epoxy resin binder bonded on the surface of the concrete member, so that the steel plate and concrete form a unified whole, the use of good tensile strength of steel plate to enhance the bearing capacity and stiffness of the member.

Steel reinforcement construction process:

Adhesive surface treatment, adhesive preparation, glue and paste, pressure curing, inspection, maintenance

The construction method

1, paste surface processing

Concrete surface chisel in addition to the whitewash layer, and then grind out the surface layer with Angle grinder 1~2mm. The larger sag shall be repaired and leveled with leveling adhesive, cleaned with a hair dryer after polishing, and reserved until the adhesive surface is dry.

B steel plate adhesive surface should be polished and derusting by Angle mill, and must be cleaned with cloth before use

2, adhesive preparation

It can be used according to the mixing ratio of the adhesive in the instructions, with a weighing device to achieve mixing, and with a stirrer to stir evenly

3, glue and paste

The adhesive is prepared and coated with greasy knife on the paste surface of the steel plate. The middle thickness is 4mm and the edge is 2mm to achieve paste. With a fixed pressure system to achieve fixed, appropriate pressure, glue just from the edge of the plate.

4, pressure curing

Pressure fixation is achieved with expansion bolts without any disturbance during curing.

5, inspection

If the anchorage area is less than 90%, the steel plate must be stripped and re-pasted.

6, maintain,

Inspection must be achieved on the surface of the steel plate epoxy red lead rust two degrees.

Steel plate reinforcement advantages: steel plate instead of steel bar, selection of high strength structural adhesive with bonding performance, the steel plate firmly bonded on the surface of the concrete member, increase the strength of the reinforced concrete structure, enhance the bearing capacity of the structure, the crack development and deflection of the member has a role. The construction is short, flat and fast, which can be realized without stopping production. It does not affect the appearance size of the structure, and the weight of the structure increases very little.
