Description

Technical Field

[0001] This application relates to the technical field of bridge construction, and more specifically, to a formwork without tie rods. Background Art

[0002] A precast T-beam refers to a beam with a T-shaped cross-section, which is an important structural member in road and bridge construction. The two protruding parts on both sides are called flanges, and the middle part is called the beam rib (or web). Since it is formed by removing the tensile zone concrete that has no effect on the bending strength in a rectangular beam, in addition to having the same bending strength as the original rectangular beam, it can save concrete and reduce the self-weight of the component at the same time.

[0003] Currently, most of the existing precast steel formworks for T-beams do not have an adjustment function. When pouring a T-beam, it is necessary to use a suitable precast steel formwork for the T-beam according to its size in order to pour a T-beam with a suitable size. This will reduce the construction efficiency and extend the delivery period, bringing inconvenience to bridge construction. Summary of the Invention

First driving mechanisms 4 are respectively connected to the mutually - remote ends of the two first side formworks 3. The first driving mechanisms 4 are arranged on the first bottom plate 1. A second driving mechanism 5 and a second side formwork 6 are arranged on the second bottom plate 2. The second driving mechanism 5 drives the second side formwork 6 to approach or move away from the first bottom plate 1.

[0031] When pouring the T - beam, the second driving mechanism 5 drives the second side formwork 6 to approach the first bottom plate 1 and stops at a set position. The first driving mechanism 4 drives the first side formworks 3 to move towards the side close to the second side formwork 6, so that a mold cavity 7 is formed by enclosing between the first bottom plate 1, the two first side formworks 3 and the two second side formworks 6, which is convenient for pouring concrete into the mold cavity 7. When demolding, the first driving mechanism 4 drives the first side formworks 3 to move away from the second side formwork 6, and then the second driving mechanism 5 drives the second side formwork 6 to move away from the first bottom plate 1.

When the motor 16 drives the threaded rod 17 to rotate forward, the second slider 18, the second vertical plate 19, the support rods 20 and the second side template 6 move synchronously towards the side close to the first bottom plate 1. When the motor 16 drives the threaded rod 17 to rotate reversely, the second slider 18, the second vertical plate 19, the support rods 20 and the second side template 6 move synchronously towards the side away from the first bottom plate 1.

[0036] In this embodiment, the support rod 20 is threadedly connected to the second side template 6, which is convenient for replacing the second side template 6 according to the use requirements. One end of the support rod 20 away from the second side template 6 passes through the second vertical plate 19, and a second limit sleeve 21 is arranged at the end of the support rod 20. The limit sleeve is used to prevent the support rod 20 from detaching from the second vertical plate 19.
