Although the application of planting bar technology in China has been only about ten years, it has the characteristics of large anchoring force, simple process, convenient operation, high efficiency, short construction period and low relative cost compared with traditional reinforcement technology. It is widely used in the renovation and reinforcement of buildings, and it has become a commonly used construction engineering technology in the strengthening and reinforcement industry. The theoretical basis of the planting bar technology is very simple, but the construction process must also strictly follow the construction process. This article will explain the process of the planting bar adhesive in detail, hoping to provide you some help:
1. Positioning: According to the position and quantity of the reinforcement of the design drawing, the position of the original structural steel bar is staggered, and the position of the planting bar is marked. Please check the relevant departments and drill holes after passing the test.
2. Drilling: Drill holes according to the dimensions required by the design drawings.
3, Clear the hole: we should clean the hole immediately after the hole is formed. Use the brush to remove the gray powder of the hole wall. It should not be less than 3 times. Use a high-pressure air gun to blow out the dust, the hole should be completely dry, use cotton yarn to take the acetone to wipe the hole wall again. If the ribs cannot be planted in time after clearing the holes, the holes must be temporarily blocked to prevent dust, gravel, etc. from entering the holes.
4, Steel decontamination: Mechanical method or wire brush to remove surface rust and oxide layer from the part of the steel bar, and then use acetone to remove residual oil on the steel. The treated steel bars should be implanted into the holes as soon as possible to avoid re-rusting or oiling.
5. Matching glue: Take A and B materials according to the amount of glue (according to the instructions for use), and mix them quickly (the injection type does not need this step).
6. Injection: The glue should be injected into the hole as soon as possible to discharge air bubbles to ensure the glue layer is full.
7. Planting reinforcement: After filling the glue, slowly rotate the screw or ribbed steel bar clockwise into the bottom of the hole. It’s better that little glue overflows, and wipe off the excess glue.
8. Curing and maintenance: After the steel bar is implanted, it is positioned on the beam bottom template, and the steel bar cannot be vibrated before the strong planting bar adhesive is completely cured.
The above is the detailed process of the construction process of the planting bar adhesive. Everyone can refer to the actual situation in the construction, but in order to ensure the quality of the planting bar, we must consider the aspects of work, materials, machine, process, environment and method.
