Specialized Seismic-Resistant Block Molding Equipment: Coordinated Design of Reinforcement Channels and Lightweight Structures

The core task of specialized molding equipment for producing seismic-resistant blocks is to manufacture special blocks that effectively reduce building weight while facilitating the insertion of reinforcing bars to form an integral framework. This requires that the equipment design integrate the precise pre-installation of reinforcement channels with the stable molding of lightweight structures as a whole, ensuring both the mechanical properties of the blocks and ease of construction.

Precise molding of reinforcement channels is crucial for ensuring structural strength. The equipment precisely sets mandrels or core-pulling devices within the mold, creating regular vertical or horizontal holes inside the block while pressing it. During construction, vertical reinforcing bars can be inserted and concrete poured into these holes to form "structural columns," or horizontal reinforcing bars can be inserted, significantly improving the integrity of the wall and its tensile and shear strength. The equipment must ensure the positional and dimensional accuracy of these channels, as well as the smoothness of their inner walls, to ensure smooth insertion of reinforcing bars and tight bonding with the subsequently poured concrete.

The molding of lightweight structures must balance weight reduction and strength. Lightweighting of masonry blocks is typically achieved by adding lightweight aggregates (such as expanded clay or foamed granules) or by creating micropores within the material. Equipment must employ a well-designed material distribution and pressurization system to ensure that these lightweight mixtures are evenly and densely pressed into every corner of the mold, forming a stable internal support structure. Simultaneously, the pressurization process must expel excess air and achieve sufficient density to guarantee strength, while avoiding excessive pressure that could damage the lightweight aggregates or the porous structure. Vibration systems are often used in conjunction with this process to promote material flow and compaction.

By coordinating the formation of the ducts and the lightweight structure within the same station and cycle, specialized equipment can efficiently and stably produce earthquake-resistant masonry blocks that combine lightweight construction, high strength, and ease of reinforcement connection. This integrated and collaborative design is a crucial equipment foundation for improving the seismic performance of building walls and realizing the industrialization and prefabrication of construction.
