Embodiment

[0033] like figure 1 and figure 2 As shown, the prefabricated T-beam of this embodiment includes a T-beam unit, the T-beam unit includes a beam rib 1 and a wing plate 2, and the wing plate 2 includes a wing top plate 21 and two wing lower plates 22, wherein the two wing lower plates 22 is the same as the current T-beam system. It is set on both sides of the top of the beam rib 1 and prefabricated with the beam rib 1 as a whole. The wing top plate 21 is laid and poured on the wing lower plate after the beam rib 1 and the wing lower plate 22 are prefabricated. 22 and the top surface of the beam rib 1, and then the lower wing plate 22 and the beam rib 1 are fixed and stressed together.

[0034] This arrangement method can only hoist the beam rib 1 and the lower wing plate 22 during hoisting, and then lay the wing top plate 21 after erection is in place. The hoisting weight is greatly reduced, and the requirements for the bearing capacity of the transportation road are low, whi...

Abstract

The invention discloses a prefabricated T-beam and a construction method. The T-beam comprises a T-beam unit, wherein the T-beam unit comprises a beam rib and a wing plate; the wing plate comprises atop wing plate and two underwing plates; the two underwing plates are arranged on the two sides of the top end of the beam rib respectively and prefabricated into a whole together with the beam rib; and the top wing plate is laid and poured on the top surfaces of the underwing plate and the beam rib. The prefabricated T-beam has the advantages of quick and convenient construction and hoisting, lowhoisting transportation requirements, good integrity, large span variation range and the like; and the construction method of the prefabricated T-beam has the advantages of simple steps, conveniencein operation, easiness in construction and the like.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a prefabricated assembled T-beam and a construction method. Background technique [0002] The prefabricated bridge adopts the prefabricated construction method. The construction environment is free from the noise and dust that are common in general construction sites. There is no need to erect supports, which can greatly speed up the construction progress and reduce the demand for construction area. This kind of construction method, which not only reduces the impact on the atmospheric environment and road traffic, but also reduces the interference on citizens' lives, is gradually occupying the field of bridge construction. [0003] The prefabricated bridge system mainly includes main girders and piers, and the structure often used for the main girder is T-beam. The existing T-beam prefabrication construction is mainly divided into integral prefabricated hoisting and segmental ...
