Description
Technical field
The present invention relates to a kind of inserted angle steel.
Background technology
Connection between current steel tower and basis divides stone bolt formula and angle steel plug-in type.Basic principal post slope is arranged to consistent with steel tower leading role steel by the slab foundation of angle steel plug-in type batter post, and foundation main capital is only by the effect of the oblique material horizontal component of tower leg, thus the active force substantially reducing foundation level direction reaches 70% ~ 90%; And the axial force on basis only increases by 1% ~ 2%, thus basic principal post, bottom slab stress situation are improved greatly, greatly can reduce the consumption of base concrete and reinforcing bar, simultaneously because the reduction of horizontal force makes toppling of basic side direction and sliding stability be significantly improved.Due to angle steel plug-in type inclined column foundation reasonable stress, reduce Foundation Design cost obvious, be therefore widely used in overhead wire engineering both domestic and external.
Existing inserted angle steel divides three kinds according to anchoring feature: pin nail anchoring type, angle steel anchoring type and pin nail angle steel mixing anchoring type.There is following shortcoming in prior art (i.e. traditional inserted angle steel): the outer profile size of inserted angle steel is comparatively large, increases difficulty, also require that basic principal post width can not design in addition too little, and cause the increase of foundation main column material cost to foundation construction; On the other hand, angle steel anchoring piece concentrates on the side of angle steel two limb, and the anchored force of anchoring piece concentrates on this side, not only makes inserted angle steel discontinuity, and enough could not play the anchorage effect of opposite side structure.
Summary of the invention
The present invention is necessary to provide a kind of inserted angle steel, and it for the deficiencies in the prior art, can reduce inserted angle steel outer profile size, and can make inserted angle steel uniform force, and inside and outside inserted angle steel, both sides all have good anchorage effect.
The object of the present invention is achieved like this:
A kind of inserted angle steel, it includes body, the outside of described body is laterally provided with at least one the first reinforcing ribs, the inner side horizontally set of described body at least one the second reinforcing rib, described first reinforcing rib and described second reinforcing rib similar to the cross sectional shape of described body, and described first reinforcing rib is corresponding with described second reinforcing rib arranges.
Preferably, the matching form outside described first reinforcing rib and described body closes, and the matching form inside described second reinforcing rib and described body closes.
Preferably, described second reinforcing rib can be replaced stiffener, matches with the interior angle of described body in a corner of described stiffener.
Preferably, the material of described stiffener is steel plate, and it is fixedly welded on described body.
Preferably, the material of described first reinforcing rib and described second reinforcing rib is reinforcing bar, and is fixedly welded on described body.
Inserted angle steel of the present invention compared with prior art, has following beneficial effect:
Reinforcing rib is set in the body medial and lateral of inserted angle steel and forms the anchoring piece of inserted angle steel, compared to existing technology in the one-sided anchoring of inserted angle steel, make not only anchorage effect strengthen one times, and make inserted angle steel stressed evenly; Arrange the stiffener with the affixed supporting role in both sides in the inner side of inserted angle steel two limb, anchorage style compared to existing technology has larger rigidity, can resist larger shearing force when anchoring piece plays a role, and strengthens the anchoring effect of inserted angle steel.
