The use steps of U-shaped channel mold are as follows: 1. Assembling mold. Tighten the bolts between the two steel molds without leaving any gap, and then brush the oil in the mold to make it easier for the concrete to demould after solidification; 2. Grouting and vibration. In order to ensure that there are not too many air bubbles in the precast concrete blocks, so as to affect the quality of U-shaped groove precast blocks; 3. Remove the mold. Wait for 1-2 days until the concrete is completely set, open the bolts on the mold and remove the mold; 4. Clean and maintain. When the mold is not in use, it should be cleaned with detergent in time, and then dried with dishcloth, and coated with oil to protect the mold. This is also a crucial step, because the steel U-channel mold is usually very strong and durable, and can be used repeatedly in production. Therefore, whether the mold can be protected when not in use and prolong the time of mold oxidation in the air is the key factor to determine the service life of the mold.
During the production of U-shaped channel mold, it is necessary to ensure that the mutual position between the steel panels is standard, which is consistent with the design drawings. The design structure of this mold is produced under the supervision of technical personnel, so it has a strong integrity. When the production is carried out, it can also bear a large pressure load and keep its own state unchanged. The overall structure of the U-shaped channel mold is very simple. The U-shaped mold is very convenient for disassembly and installation. When we remove the mold, we do not use special demoulding equipment, but directly remove the steel formwork. Most of these large steel molds will use reinforced bolts, The specification size of the bolt is suitable for the volume of the steel mold, and it will also be marked on the construction drawings. The bolts of the same specification can be prepared in advance for replacement to ensure the safety of construction.
