Abstract

The utility model relates to a pull bar expansion mechanism, in particular to a pull bar expansion mechanism for a steel structure. The pull bar expansion mechanism comprises a purline, a middle pull bar which extends downwards is arranged in the purline, a steel pipe supporting rod is sleeved outside the middle pull bar, the upper portion of the steel pipe supporting rod abuts against the bottom of the purline, an upper pull bar which extends upwards is arranged on the upper portion of the purline, and an inclined pull bar which inclines outwards is arranged in the purline. The pull bar expansion mechanism for the steel structure is simple in structure and can improve supporting performance.

Description

The tie rod extension mechanism that is used for steel work
Technical field
The utility model is a kind of tie rod extension mechanism, particularly a kind of tie rod extension mechanism for steel work.
Background technology
Steel work of the prior art, complex structure, support strength is low.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of compact conformation is provided, and promotes the tie rod extension mechanism that is used for steel work of support performance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of tie rod extension mechanism for steel work, comprise purlin, be provided with the middle tie rod of downward extension in the described purlin, tie rod is with the steel pipe strut outward in the middle of described, the top of described steel pipe strut and the bottom of purlin connect, the top of described purlin is provided with upwardly extending top brace, is provided with outward-dipping batter brace in the described purlin.
As preferably, described in the middle of the left side of tie rod be provided with batter brace, described in the middle of the right side of tie rod be provided with top brace, described in the middle of tie rod, top brace and batter brace regulate fixing by adjusting nut mutually with purlin respectively.
Therefore, the tie rod extension mechanism that is used for steel work that the utility model provides, simple in structure, promote supportive.
