Abstract

The utility model discloses a kind of steel structural embedded parts that can bear larger pulling force, comprise the pre-embedded steel slab and the some pull bars be embedded in concrete and end plate that are exposed to concrete surface, every root pull bar one end is welded with corresponding end plate respectively, and the pull bar other end is welded on pre-embedded steel slab jointly.Pull bar is made up of angle tie and two kinds, steel plate pull bar, and its light plate pull bar is positioned in the middle part of matrix, and angle tie is positioned at matrix both sides.Angle tie is respectively provided with the peg of a row perpendicular to limit, place inside two limits, and the peg on two limits is crisscross arranged.The utility model, under the limited condition in embedded part locus, still can meet the requirement of embedded part by larger tension pull out force, well solve the technical barrier run in construction.This embedded part decreases the space that component takies, and is convenient to the installation of indented bars.

Description

A kind of steel structural embedded parts that can bear larger pulling force
Technical field
The utility model relates to a kind of steel structural embedded parts being applicable to large-scale steel structure bearing, and this built-in fitting can improve tension pull out force greatly, belongs to technical field of buildings.
Background technology
Steel building is generally used for the position that roof system etc. needs large span and moulding complexity, and the position that beam column etc. transmit vertical gravity still adopts concrete structure usually.The contact of concrete structure and steel work and power transmission have come by arranging built-in fitting usually.Built-in fitting needs to bear moment of flexure, shearing, pressure and pulling force.Wherein born shearing is determined by the shear strength of bottom pull bar; Pressure directly passes to concrete by steel plate; Moment of flexure is born by built-in fitting eccentric force (local pressure, local is drawn); Pulling force is then born by the bond stress of concrete to pull bar in built-in fitting, mechanical snap power to end plate.
For large span spatial structure, dead load is large, and bearing place is set to hinged form usually, requires high to the tension of bearing.Tradition steel structural embedded parts generally arranges reinforcing bar as bottom pull bar, by arranging end plate or bending pull bar bottom with the tension pull out force increasing component.But due to the restriction by embedded part installation site and erection space, if adopt traditional embedded board lower end to arrange the method for reinforcing bar crotch connection again, need the reinforcing bar that band crotch intensive is in a large number set in embedded part lower end.Obviously, owing to there being larger pulling force, the whole embedded part that the method is buried underground and concrete friction and the pulling capacity produced can not meet the demands.
Summary of the invention
For prior art above shortcomings, the purpose of this utility model still can improve the steel structural embedded parts of tension pull out force greatly under being to provide a kind of condition limited in embedded part locus.
For achieving the above object, the technical solution of the utility model is achieved like this:
A kind of steel structural embedded parts that can bear larger pulling force, comprise the pre-embedded steel slab and the some pull bars be embedded in concrete and end plate that are exposed to concrete surface, pull bar and end plate one_to_one corresponding, every root pull bar one end is welded and fixed with corresponding end plate respectively, all pull bar other ends are welded on pre-embedded steel slab jointly, all pull bars are matrix arrangements, and pre-embedded steel slab and end plate be arranged in parallel.
Further, described pull bar is made up of angle tie and two kinds, steel plate pull bar, and its light plate pull bar is positioned in the middle part of matrix, and angle tie is positioned at matrix both sides.
Further, described angle tie is respectively provided with the peg of a row perpendicular to limit, place inside two limits, and the peg on two limits is crisscross arranged.Peg structure increases angle tie and concrete snap-in force further.
Compared to existing technology, the utility model has following beneficial effect:
1, this embedded part is applicable to the large-span steel embedded part by position limitation, under the condition that embedded part locus is limited, still can meet the requirement of embedded part by larger tension pull out force, well solve the technical barrier run in construction.
2, this embedded part does not adopt traditional embedded part bottom to have the form of crotch, directly uses angle steel, peg and steel plate etc., decreases the space that component takies, be convenient to the installation of indented bars.
3, this embedded part is suitable for factory process, and the quantity of peg can adjust according to the requirement of stretching resistance, arranges flexibly.If made in enormous quantities, effectively can reduce cost of manufacture, and then reach the object of saving construction cost.
Accompanying drawing explanation
Fig. 1-the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, upper as can be seen from figure, the utility model can bear the steel structural embedded parts of larger pulling force, comprise pre-embedded steel slab 1 and some pull bars and end plate 5, pull bar and end plate 5 one_to_one corresponding, every root pull bar one end is welded and fixed with corresponding end plate 5 respectively, and all pull bar other ends are welded on pre-embedded steel slab 1 jointly, all pull bars are matrix arrangements, and pre-embedded steel slab 1 and end plate 5 be arranged in parallel.
Described pull bar is made up of angle tie 2 and 3 two kinds, steel plate pull bar, and its light plate pull bar 3 is positioned in the middle part of matrix, and angle tie 2 is positioned at matrix both sides, is convenient to like this wear indented bars, ensures that intensive screw-thread steel passes.Wherein respectively be provided with a row inside angle tie 2 two limits to be crisscross arranged perpendicular to the peg 4 on peg 4, two limits on limit, place.Peg 4 structure increases angle tie and concrete snap-in force further.Simultaneously upper as can be seen from figure, all angle ties are oppositely arranged between two.
Pre-embedded steel slab 1 in this steel structural embedded parts is exposed to concrete surface, remaining angle tie 2, steel plate pull bar 3, end plate 5 and peg 4(screw) be all embedded in concrete.Owing to will bear the tension pull out force of increasing, the thickness of pre-embedded steel slab 1 should be thicker, meets the requirement of pull bar weld seam; Arranging angle tie 2 is that have more contact area with concrete, be convenient to weld more peg 4 at angle steel upper inner surface, the effect of peg 4 can strengthen the occlusal contact area with concrete structure because the external surface area of angle steel is comparatively large, increases the tension pull out force of structure.Steel plate pull bar 3 is compared with traditional steel bar rod simultaneously, increases and concrete contact area, also just means and increase the bond stress of concrete to component; Increase cross-sectional area simultaneously, there is better shearing resistance effect.The setting of end plate is compared with the bending of reinforcing bar, and concrete is engaged better effects if to it, and stretching resistance is stronger.
Actual processing request: 1) adopt fillet weld to be connected between pre-embedded steel slab with pull bar, the height of pre-embedded steel slab thickness and weld seam will meet the needs of stretching resistance.2) between peg and angle tie, also employing is welded to connect, and just should weld before angle tie welds with pre-embedded steel slab.3) end plate is also be welded on pull bar, and weld seam should meet resistance to plucking needs.
Above embodiment only illustrates the technical solution of the utility model and unrestricted, although be described in detail utility model scheme with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in right of the present utility model.
