Self-propelled hydraulic T-shaped beam prefabricating template device and demolding method thereof

Abstract

The invention discloses a self-propelled hydraulic T-shaped beam prefabricating template device and a demolding method thereof. The self-propelled hydraulic T-shaped beam prefabricating template device comprises a template device body composed of side mold devices (1), an end mold device (2) and a bottom mold device (3). Longitudinal moving devices (6) are arranged between the template device body and guide rails (5) on concrete foundation faces (4). Hydraulic transverse moving devices (7) are arranged between the longitudinal moving devices (6) and the side mold devices (1). Hydraulic jacking rod type vertically-moving devices (21) are arranged between the hydraulic transverse moving devices (7) and the side mold devices (1). According to the self-propelled hydraulic T-shaped beam prefabricating template device and the demolding method, the mold combination and demolding processes are controlled in a hydraulic manner, the automation degree is high, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of prefabricated T-beams in railway and highway construction, in particular to a self-propelled hydraulic T-beam prefabricated formwork device and a demoulding method thereof. background [0002] China Invention Patent Application No. 201310325089.4, titled: T-beam formwork overall removal and longitudinal sliding construction method, from the disclosure content of the patent, the present invention realizes the complete disassembly and assembly of T-beam formwork on one side, compared with traditional formwork construction technology A large number of joints in the section formwork are reduced, which is beneficial to ensure the uniform size of the beam body and improve the appearance quality of the beam body; Construction cost: the invention can improve the operation efficiency of formwork engineering construction, effectively shorten the turnover period of formwork engineering, realize the reduction of the number of...

Problems solved by technology

When the formwork has reached the design demolition strength, when this method is used to remove the side formwork, each half of the side formwork is pulled synchronously by manpower using four ratchet wheels and the side formwork is tilted and separated from the concrete surface. This process requires The action of the ratchet wheels is coordinated. If the adjustment of each ratchet wheel is inconsistent or out of sync, it will increase the demoulding resistance and increase the deformation of the template, reducing the service life of the template

The separation process of the side formwork and the T-beam requires manual and synchronous adjustment of the ratchet wheel, and requires the ratchet wheel to move in unison, so the process of removing the formwork is time-consuming and laborious and has a low degree of automation; at the same time, when moving longitudinally, an external winch is used for traction. The overall integration of the device is low
