Abstract
The invention discloses a pull rod with a cross short column. The pull rod is characterized in that the pull rod is a cylindrical or elliptic cylindrical pull rod, a plurality of short columns connected with the pull rod are arranged on the pull rod, the short columns are arranged at intervals with an angle, and the short columns are one of cylindrical, elliptic cylindrical, square cylindrical and elongated columns. The pull rod with the cross short column is used for solving a problem of stress concentration caused by connection of a flexible or thin-wall material pull rod type self-bearing earth-retaining wall on lateral flexible or thin-wall materials.
Description
Technical field
With intersecting the pull bar of short column, for flexibility or thin-walled material, add the pull bar of rod-pulling type self-supporting retaining wall.
Background technology
At flexibility or thin-walled material, add in the construction of rod-pulling type self-supporting retaining wall and use general pull bar, can produce stress and concentrate during connection, cause flexibility or thin-walled material to destroy, the safety that flexibility or thin-walled material is added to rod-pulling type self-supporting retaining wall causes harmful effect.
Summary of the invention
A pull bar with intersection short column, is characterized in that: a cylindrical or elliptical cylinder-shape pull bar, on pull bar, there are some short columns that are connected (being to intersect originally) with pull bar, and between each short column, there is angle intervals, short column is cylindrical or elliptical cylinder-shape; Described pull bar is a kind of in cylindrical, elliptical cylinder-shape; Described short column is a kind of in cylindrical, elliptical cylinder-shape, disk.Angle intervals between described short column, its scope is 0 ° ~ 90 °; When described short column is disk, disk radially and pull bar axially between angulation be spaced apart 0 ° ~ 90 °; Described short column is at least 2.
Use connects flexibility or the thin-walled material of offside with intersecting the pull bar of short column, the problem of stress concentration of generation when having eliminated general pull bar and being connected with flexible material, and the safety that makes flexibility or thin-walled material add rod-pulling type self-supporting retaining wall improves greatly.And owing to having certain intervals between each short column, when the flexibility of different-thickness or thin-walled material self-supporting retaining wall connect offside flexibility or thin-walled material, can cut and not destroy the use function of this pull bar, the part cutting by welding, freely the mode such as bundle and can form a new pull bar with intersection short column and use; On pull bar with intersection short column when connecting offside flexibility or thin-walled material, imbed the part of backfilling material due to the effect of short column, increased frictional force, its tensile strength can be better utilized, so, pull bar with intersection short column also can be used as anchor pole use, better than the effect of general friction anchor pole.

The specific embodiment
Take with intersecting the pull bar of short cylindrical is below example, introduces the specific embodiment of the present invention.
When flexibility or thin-walled material add the construction of rod-pulling type self-supporting retaining wall and socket offside flexible material, first measure the distance between offside flexibility or thin-walled material, then the pull bar with intersection short column is cut according to the distance recording, owing to 2. intersecting the existence of short cylindrical, when before and after making, 4. flexibility or thin-walled material socket in both sides, can be enclosed within 1. on pull bar and unlikely coming off, and then use backfilling material that this pull bar is covered to compacting, as shown in Figure 5.2. the short cylindrical of these intersections makes pull bar not only realize drawing-resistant function with frictional force in backfilling material, so while socketing the 4. flexibility of offside or thin-walled material, given full play to the tensile strength of pull bar itself.
In addition, for stablizing massif when construction, the scope of operation one side is not laid 4. flexibility or thin-walled material, now, can 2. intersect the effect of short column and makes anchoring more firm directly anchoring into the scope of operation with intersecting the pull bar of short column, utilizing.
