Description
Technical Field
[0001] This utility model belongs to the field of construction technology of T-beam formwork cleaning equipment, and relates to a T-beam bottom formwork grinding and cleaning mechanism. Background Technology
[0002] The formwork system in the T-beam production line consists of three parts: side formwork, bottom formwork, and end formwork. The side formwork is fixed, while the bottom formwork is a longitudinally moving bottom formwork platform. Due to the change in beam length, the relationship between the side formwork and the end formwork is that the side formwork is wrapped around the end.
[0003] Main materials for side formwork: Stainless steel panels for the front panels and T12 steel strips for the connecting plates. Side formwork demolding method: Automated mold closing and demolding via a hydraulic system. Side formwork connection method: Beams are connected as a whole along their length using bolts, and connected as a whole along their cross-section using upper and lower tie rods. Shared side formwork method: Considering beam length variations of ±500mm for spans of 25m / 40m, the side formwork length is designed to be 26m / 40m, and the beam height is designed to be 1.75m / 2.5m. To save on formwork, prefabrication of 80-type and 160-type expansion joints is achieved by replacing movable blocks at the beam ends. Side formwork types: Side formwork is divided into center beam side formwork and edge beam side formwork. Both center beam and edge beam side formwork consist of five main parts: formwork section, bottom support, sliding block, comb plate, and platform system.
[0004] The movable bottom formwork platform consists of three main parts: the bottom formwork template, the main beam, and the longitudinal trolley. The bottom formwork template is placed directly on the main beam, and the traveling system is assembled with the main beam as a whole via connecting plates. The bottom formwork template is made of T6 steel plate, with channel steel used for longitudinal reinforcement at the bottom of the panel. The bottom formwork width is designed to be 600mm, and movable templates are designed at the bottom lifting points of the beams for easy lifting. The main beam adopts a double-section H-beam steel structure, divided into three sections, with the longest single section being 12m. The longitudinal trolley consists of four main parts: wheel boxes, wheel sets, drive unit, and motor protective cover.
[0005] End formwork: The end formwork is connected to the side formwork using a side formwork clamping method. The end formwork panel is made of T6 steel plate, and the connecting plates and reinforcing ribs are all made of T8 steel strip. The end formwork is placed directly above the bottom formwork (concrete surface), and the top surface of the end formwork has a 2% slope; sealing strips are installed at the connection points between the end formwork and the bottom and side formwork to ensure strong sealing and prevent grout leakage during prefabrication.
[0006] After the movable bottom formwork platform is demolded after construction is completed, it usually needs to be manually polished, which is time-consuming and labor-intensive. Utility Model Content
