Abstract

The utility model discloses a prestressed concrete pretensioned box girder prefab tension transfer column, and a tension transfer column (1) meets the demand of the tension of broken line bars of a box girder, wherein, the end (c) of the tension transfer column (1) in a step shape (a), the tension transfer column (1) adopts a reinforced concrete structure, a steel plate (3) with 30 mm, spring rods (6) and four layers of reinforcing steel bar net slices (4) are arranged on the end of the tension transfer column (1). The end of the tension transfer column (1) expands the width of 2.5m so that a jack and a spiral support (5) can be arranged on the lower end of the tension transfer column (1). The utility model can meet the demands of the tension of the straight line bars and the broken line bars of the box girder and the interaction space of tension equipment, and can bear the tensioning force of 52000kN of the box girder.

Description

The beam prefabricated force-transmitting pole of prestressed concrete pre-tensioned case
Technical field
It is prefabricated that the utility model relates to beam bridge, particularly relates to the beam prefabricated force-transmitting pole of the prestressed concrete pre-tensioned case of a kind of 32m/900t.
Background technology
China began one's study from 1958 and manufactures experimently first Zhang Liang, but because form of reinforcement adopts the straight line arrangement of reinforcement, the beam maximum span of opening earlier commonly used is confined to below the 20m.Calendar year 2001 seeks advice from (Railway Special Design Inst) by middle iron and presides over, the design and the manufacturing process research of broken-line reinforcement pretensioning prestressed concrete T beam have been finished, obtained certain data and experience, a broken-line reinforcement elder generation beam technology has been widely used in Qinghai-Tibet Railway span T beam commonly used at present.The first Zhang Liang that adopt in Taiwan successively mixes to open structure, and span is 27.5m, and its broken-line reinforcement adopts post stretching to apply the prestressing force form.(1) prior art fails to solve the case beam that adopts broken-line reinforcement.(2) prior art fails to solve the pre-tensioning system prefabricated case beam that tension tonnage reaches 52000kN.
The utility model content
The purpose of this utility model provides the strong beam prefabricated force-transmitting pole of prestressed concrete pre-tensioned case of a kind of holding capacity.
In order to achieve the above object, the utility model adopts following technical scheme: the beam prefabricated force-transmitting pole of a kind of prestressed concrete pre-tensioned case, and force-transmitting pole can carry out stretch-draw to case beam broken line muscle, and the end of force-transmitting pole is step-like.
Described force-transmitting pole adopts reinforced concrete structure, and steel plate, spring muscle and reinforced mesh are installed on the force-transmitting pole end sides.
The upper end is wider than in lower end, described force-transmitting pole end, and lower end, force-transmitting pole end is installed by jack and spiral supports.
The both sides, upper end at described force-transmitting pole middle part are the inclined-plane.
Steel plate thickness on the described force-transmitting pole end sides is 30mm, and reinforced mesh is four layers.
Described force-transmitting pole end spreads to 2.5m.
The utility model has the advantages that:
(1) the force-transmitting pole end is designed to step-likely, so that the stretch-draw top rail is installed on step, satisfies the stretch-draw of case beam broken line muscle.
(2) force-transmitting pole adopts the C50 reinforced concrete structure, can satisfy case beam 52000kN stretching force and non-unstability; End jack active position adopts 30mm steel plate, spring muscle and 4 layers of reinforced mesh to strengthen, and guarantees the intensity in the concrete partial pressing in 52000kN stretching force bottom.
(3) the force-transmitting pole end spreads to 2.5m so that jack is installed and the spiral support.
(4) force-transmitting pole can satisfy straight, the broken line muscle stretch-draw of case beam simultaneously.
(5) force-transmitting pole can bear case beam 52000kN stretching force.
(6) force-transmitting pole can satisfy the action space of tensioning equipment.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 passes post end internal construction schematic diagram in the utility model;
Fig. 3 passes the post end structural representation in the utility model;
Fig. 4 passes column central structure schematic diagram in the utility model.
The specific embodiment
The structure of the beam prefabricated force-transmitting pole of a kind of prestressed concrete pre-tensioned case of the utility model such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: force-transmitting pole 1 can satisfy the stretch-draw of case beam broken line muscle, the both sides, upper end of described force-transmitting pole middle part b are the inclined-plane, the end c of force-transmitting pole is that step-like (there is step the end that is force-transmitting pole a), so that the stretch-draw top rail is installed on step a, is satisfied the stretch-draw of case beam broken line muscle.Force-transmitting pole 1 adopts reinforced concrete structure, can satisfy case beam 52000kN stretching force and non-unstability; Steel plate 3, spring muscle 6 and 4 layers of reinforced mesh 4 of 30mm thickness are installed on the force-transmitting pole end sides, guarantee intensity in the concrete partial pressing in 52000kN stretching force bottom.The force-transmitting pole end spreads to 2.5m, so that jack and spiral support are installed, jack and spiral support 5 is installed in the lower end, force-transmitting pole end.
