Problems solved by technology

Most of the existing cover beams are erected on the pier columns through anti-seismic bearings. During long-term use, the cover beams tend to slide horizontally or vertically relative to the pier columns, which brings serious safety hazards to the use of bridges.

Embodiment Construction

[0027] Such as Figure 1~2 As shown, a cover beam and pier column integrated formwork structure of the present invention includes a cover beam formwork 1 and a pier column formwork 2, the cover beam formwork 1 and two pier column formworks 2 are combined, and the bottom of the cover beam formwork 1 is opened There are sockets 3 for the pier formwork 2 to pass through; the cover beam formwork 1 is connected with a first reinforcement cage 4, and the cover beam formwork 1 is formed by a steel plate structure, and the cover beam formwork 1 and The first reinforcement cage 4 is fixedly matched and welded with the first reinforcement cage 4 . An annular support reinforcement cage 5 is arranged around the insertion hole 3 around the insertion hole 3 . The annular support reinforcement cage 5 is annular, and its axis is vertical, corresponding to the extension direction of the pier formwork 2 .

[0028] Specifically, the annular support reinforcement cage 5 is fixedly connected to t...

Abstract

The invention discloses a cover beam and pier column integrated formwork structure, and belongs to the technical field of building bridges, the cover beam and pier column integrated formwork structure comprises a cover beam formwork and a pier column formwork, and the bottom of the cover beam formwork is provided with an insertion hole for the pier column formwork to penetrate through; a first steel reinforcement cage is connected into the cover beam formwork, the cover beam formwork is of a steel plate structure and is fixedly matched with the first steel reinforcement cage, an annular supporting steel reinforcement cage is arranged on the periphery of the inserting hole around the inserting hole, and a rotating supporting component is arranged at the upper end of a second steel reinforcement cage. The second reinforcement cage is located in the annular supporting reinforcement cage after penetrating into the insertion hole, and the second reinforcement cage is erected on the annular supporting reinforcement cage through the rotary supporting component. The integrated formwork structure can be used for integrally pouring a cover beam and a pier column, and through prefabrication forming in a factory, the construction efficiency and quality are improved, the construction precision of a bridge is guaranteed, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of building bridges, and in particular relates to a cover-beam-pier-column integrated formwork structure. Background technique [0002] The cover beam refers to the beam set on the top of the bent pile pier for supporting, distributing and transmitting the load of the superstructure. Also known as hat beam. The cover beam refers to a bridge with two piers, and a reinforced concrete or less-reinforced concrete beam is set on the pier (platform) or row of piles. The main function is to support the superstructure of the bridge and transfer all loads to the substructure. Most of the existing cover beams are erected on the pier columns through anti-seismic bearings. During long-term use, the cover beams tend to slip laterally or vertically relative to the pier columns, which brings serious safety hazards to the use of bridges. Contents of the invention [0003] In view of this, the purpose of the present inv...
