If the wall material is hard during the installation process, will it affect the expansion effect and fixing strength of the Carbon Steel Hit Anchor With Flange Nut?

When installing Carbon Steel Hit Anchor With Flange Nuts, encountering a hard wall material may indeed affect its expansion effect and fixing strength. Hard wall material means that the expansion tube encounters greater resistance when expanding in the drill hole. This may cause the expansion tube to fail to fully expand to the preset diameter, thereby reducing the friction grip between the wall. In a hard wall, the expansion tube may expand unevenly due to uneven force, forming local high-pressure or low-pressure areas. This uneven expansion will affect the overall fixing effect of the anchor bolt and reduce its stability and safety.
When the expansion effect is not ideal, the problem of preload transmission between the anchor bolt and the wall becomes prominent. Preload is the core of the anchor bolt fixing effect. It ensures that a strong friction grip is formed between the anchor bolt and the wall to resist external loads. However, if the expansion process is blocked, resulting in the anchor bolt failing to fully expand to the designed state, the preload will not be fully transmitted to the wall to form an effective connection. When subjected to external forces, such as wind, earthquake forces, or the gravity of the structure itself, anchor bolts are prone to loosening due to lack of sufficient holding force. Over time, this loosening may gradually increase, eventually causing the anchor bolt to fall off completely, rendering the connection ineffective. Secondly, even if the anchor bolt does not fall off completely, insufficient preload will reduce its overall fixing strength, making the structure more vulnerable to external loads and increasing the risk of structural damage or collapse. Anchor bolts with stronger expansion force and higher load-bearing capacity can maintain effective expansion effect in the face of high resistance, ensuring sufficient transmission of preload force. These anchor bolts are usually made of more advanced expansion mechanisms or stronger materials to cope with the special requirements of hard walls.
For hard walls, anchor bolt models with stronger expansion force and higher load-bearing capacity should be selected. This ensures that the anchor bolt can overcome greater resistance during expansion, achieve full expansion and stable fixation. Before installing the anchor bolt, you can use tools such as electric drills to pre-drill holes in the wall. The diameter and depth of the pre-drilled holes should be reasonably selected according to the specifications of the anchor bolts and the wall material to ensure that the anchor bolts can be installed smoothly and give full play to their expansion effect.
During the installation process, the inspection of the quality of anchor bolt installation should be strengthened. By checking the expansion of the anchor bolts, the transmission of preload force, and the structural stability, ensure that the fixing strength and safety of the anchor bolts meet the design requirements. Formulate and follow standardized installation steps and operating procedures to ensure that each installation link meets the specified quality requirements. During the installation process, appropriate detection tools should be used to monitor and record the expansion, preload force, and structural stability of the anchor bolts in real time. These data are essential for evaluating the installation quality and subsequent maintenance. Provide professional training for installers to improve their technical level and safety awareness. At the same time, strengthen supervision and management of the installation process to ensure that all operations meet specifications and safety requirements.
