Precise positioning template device for concrete pull rod or dowel bar and using method

Abstract

A concrete pull rod or dowel bar accurate positioning formwork device comprises a formwork and a positioning perforated plate, the formwork comprises a first formwork body and a second formwork body, the second formwork body is fixedly connected to one side of the first formwork body, and the positioning perforated plate is fixedly connected to the other side of the first formwork body; the positioning perforated plate is provided with a long-strip-shaped through hole used for containing a pull rod or a dowel bar. Penetrating holes corresponding to the long-strip-shaped penetrating holes in the positioning perforated plate are formed in the first template and the second template; and the pull rod or the dowel bar sequentially penetrates through the positioning perforated plate, the first template and the second template. The accurate positioning template device for the concrete pull rod or the dowel bar disclosed by the invention is wider in application range, and can be suitable for the condition that the pull rod or the dowel bar has different distances; positioning can be rapidly and accurately carried out, installation is faster and more convenient, and the working efficiency is greatly improved; the device can be manufactured at a time and recycled, and the construction cost is effectively saved.

Description

technical field [0001] The invention belongs to the technical field of road engineering construction, and particularly relates to a concrete tie rod or dowel rod precise positioning formwork device and a use method. Background technique [0002] During the construction of concrete pavement, expansion joints shall be set up as required, and tie rods or dowel rods shall be evenly arranged in the expansion joints to transmit the traffic load between two adjacent pavement slabs, prevent misalignment, and transmit stress to make adjacent concrete blocks common force. [0003] At present, tie rods or dowel rods are mainly bound and fixed by steel support brackets. This kind of fixing method has complicated construction process, low work efficiency, large positioning error of tie rods or dowel rods, and small contact surface between the bottom of the steel support bracket and the lower bearing layer. , In the process of concrete pouring, due to the vibration of the vibrating rod, ...

Problems solved by technology

[0003] At present, steel bar brackets are mainly used to bind and fix tie rods or dowel bars. This fixing method has cumbersome construction technology, low work efficiency, large positioning errors of tie bars or dowel bars, and small contact surface between the bottom of steel bar brackets and the underlying layer. , in the process of concrete pouring, due to the vibration of the vibrating rod, it is very easy to cause the position deviation of the steel support and the tie rod or dowel bar, so that the tie rod or dowel bar cannot play its due effect
