Problems solved by technology
[0002] There are usually three ways to set the tie bars of building filling walls: one is to use pre-embedding, which will destroy the formwork, and is time-consuming and material-consuming, so it is not commonly used at present; The iron parts are easy to shift and the cost is high; the third way is to plant bars, which has been banned by many local construction authorities because of its tensile performance and durability.

The invention mainly solves the technical problem that a building infilled wall tie bar structure which not only can ensure tie bar position to be accurate but also has reliable connection, simple structure and convenient operation. The invention adopts the following technical scheme: the tie bar comprises a steel bar body, one end of the steel bar body is provided with an outer thread, the other end is bent into 90 degrees, the steel bar body is connected with an expanding unit arranged in a concrete construction member by a thread, the expanding unit comprises a conical body, a sleeve, a spacer, a spring washer and a pipe fitting which are sequentially connected from inside to outside; wherein the conical body and the pipe fitting are internally provided with an inner thread matched with the outer thread of the steel bar body, and the sleeve is provided with a groove body along radial direction. The invention is used for masonry of building wall.
Description
technical field [0001] The invention discloses a tie bar structure for building filling walls, which is used for masonry of building walls and belongs to the technical field of building construction tools. Background technique [0002] There are usually three ways to set the tie bars of building filling walls: one is to use pre-embedding, which will destroy the formwork, and is time-consuming and material-consuming, so it is not commonly used at present; Rebars, iron parts are easy to shift and the cost is high; the third method is to plant rebars, which has been banned by many local construction authorities because of its tensile properties and durability to be proved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tie bar structure for building filling walls, which can not only ensure the accurate position of tie bars, but also have reliable connection, simple structure and convenient operation. [0004] In...
