Embodiment Construction

[0020] A high-efficiency steel-concrete composite girder deck formwork structure of the present invention is provided with reserved holes during processing of the I-shaped steel beam, and the composite formwork structure is fixed on the I-shaped steel beam through high-strength bolts and nuts, wherein the composite formwork structure includes Square steel pipe, square wood and clear water formwork, using plastic sleeves to isolate concrete and high-strength bolts. The formwork structure can be applied to the paving process of the I-beam-concrete composite girder deck.

[0021] figure 1 , figure 2 with image 3 It is a specific implementation example of the construction and usage of a high-efficiency I-beam-concrete composite girder bridge deck formwork, such as figure 1 with figure 2 As shown, the construction method is mainly composed of I-shaped steel beam 1, high-strength bolt 2, nut 3, plastic sleeve 4, square steel pipe 5, square wood 6, and clear water formwork 7. ...

Abstract

The invention discloses an efficient steel-concrete combined bridge panel template structure and an application method, and belongs to the technical field of bridge construction. The efficient steel-concrete combined bridge panel template structure mainly comprises an I-shaped steel beam, a high-strength bolt, a nut, a plastic sleeve head, a square steel pipe, a timber and a clear water template.A reserved hole is formed when the I-shaped steel beam is machined; the high-strength bolt and the nut are used for fixing a combined template structure; the bolt and concrete are separated by adopting the plastic cover head; the concrete can be paved on the combined template structure; after construction, the high-strength bolt and the combined template structure only can be manually dismounted;the nut and the plastic sleeve head are positioned in the concrete to finish the paving work of the bridge panel concrete; the template structure is portable; the stress mechanism is clear; the high-strength bolt is difficultly deformed; the mounting and the dismounting are convenient; and secondary repair is not needed after the concrete pavement.

Description

technical field [0001] The invention relates to a bridge deck formwork structure and usage in the technical field of bridge construction, in particular to a high-efficiency I-beam-concrete composite beam bridge deck formwork structure and usage. Background technique [0002] In the field of bridge construction, the steel-concrete composite structure can effectively reduce its own weight, improve the spanning capacity, and has a wide range of applications and prospects. The most common one is the I-beam-concrete composite structure. At present, there is no relevant bridge deck formwork specification in the field of bridge construction. Bridge deck pouring construction methods are different. I-beam-concrete composite structure poured concrete bridge decks often use combined formwork or integral steel formwork, using scaffolding for support, or setting round Holes and horizontal pins are used to fix the formwork, and the construction steps are often complicated, requiring a lot...
