Description

Technical Field

[0001] This utility model belongs to the field of concrete building mold technology, specifically relating to a partial forming mold for precast wall panels. Background Technology

[0002] Precast wall panels are typically connected to each other or to precast beams using connectors. Threaded sleeves are embedded within the precast wall panels, and the connectors are secured to these sleeves with fastening bolts. The connectors are usually plates of a certain thickness.

[0003] To prevent the connector from protruding or protruding slightly from the wall panel surface, a recessed groove is usually provided on the wall panel surface corresponding to the threaded sleeve, with the end face of the threaded sleeve flush with the bottom surface of the recessed groove.

[0004] Currently, the common practice is to place an extruded polystyrene board on top of the threaded sleeve, and then pour concrete to manufacture precast wall panels. After the concrete has initially set, the extruded polystyrene board is removed, creating a sinkhole in its original position.

[0005] However, extruded polystyrene boards are prone to gaps with threaded sleeves during pouring, causing grout to seep into the threaded sleeves, affecting their use and installation. Utility Model Content
