Problems solved by technology

However, this method has shortcomings in terms of construction difficulty, replaceability, and observation of the tension state of transverse prestressed tendons.
In addition, it is difficult to solve the problem that the prestressed short beam prestressed loss (especially the anchorage deformation loss) is too large in the conventional method.

Embodiment Construction

[0035] The present invention utilizes the left and right lateral positioning blocks to pull the lateral prestressed tendons close together, so as to achieve the purpose of stretching, strengthen the lateral connection and force of the beam body, effectively simplify the construction difficulty, reduce the construction cost, and improve the Construction efficiency, when the component is deformed or damaged and can be replaced at any time, it has good practical value and application prospects.

[0036] Below in conjunction with accompanying drawing, structure of the present invention, construction process are described in detail:

[0037] A transverse prestressing system such as figure 1 As shown, it includes a left transverse positioning block 1.1 and a right transverse positioning block 1.2, and two or more adjacent bundles of prestressed steel beams 4 are respectively nested on the left transverse positioning block 1.1 and the right transverse positioning block. The position...

Abstract

The invention discloses a transverse prestressed system and a construction method thereof. The transverse prestressed system comprises a left transverse positioning block (1.1) and a right transversepositioning block (1.2), and adjacent prestressed steel beams (4) are embedded into the left transverse positioning block (1.1) and the right transverse positioning block (1.2) in a sleeved mode correspondingly; and the left transverse positioning block (1.1) and the right transverse positioning block (1.2) are fixed together through a transverse connecting plate (2.1), and thus tensioning of theprestressed steel beams (4) is achieved. The construction method comprises the following steps that (1) the adjacent prestressed steel beams (4) are embedded into the left transverse positioning block(1.1) and the right transverse positioning block (1.2) in the sleeved mode correspondingly; (2) then the left transverse positioning block (1.1) and the right transverse positioning block (1.2) are closed together to be tensioned through a tensioning device; and (3) then the transverse connecting plate (2.1) is embedded into the position between the left transverse positioning block (1.1) and theright transverse positioning block (1.2) and fixed. The transverse prestressed system is simple in structure, high in practicability, simple in construction method and easy to replace.

Description

[0001] Field [0002] The invention relates to a transverse prestressing system and a construction method thereof, belonging to the technical field of bridge engineering. Background technique [0003] The prestressing technology has a history of more than 50 years, and it is a technology that appeared after the development of reinforced concrete, especially reinforced concrete technology. Mainly use the high tensile strength of steel bars to make up for the lack of concrete tensile capacity, improve the overall tensile, bending, shearing and compressive capacity of concrete structures, and make the beams, slabs, etc. of concrete structures have larger spans, columns, piles, etc. The carrying capacity is greater. Compared with the longitudinal prestress, the transverse prestress can effectively improve the lateral connection and stress of the beam body. Generally, the stretching of transverse prestressing is consistent with the traditional longitudinal prestressing method, wh...
