Description
Technical field
The present invention relates to combination beams, especially double steel plate Combination beam of steel and concrete, it can be widely applied to various buildings
In structure.
Background technology
At present in combined structure system, beam mainly has clean steel beam, girder with rolled steel section en cased in concrete, girder steel top flange and Combined concrete
The forms such as combination beam.
Clean steel beam is predominantly I-shaped, H-type and box form, does not include any concrete, it is big that there are steel using amounts, and girder steel is rigid
Spend weak disadvantage.In the surrounding of clean steel beam, it is more that there are concrete amounts for steel reinforced concrete Liangqi concrete outsourcing, need increase compared with
More amount of reinforcement, the disadvantage of bar connecting and concreting difficulty.The combination beam of girder steel top flange and Combined concrete is
Peg is arranged in I-shaped or Investigation of Reinforcing Rectangular Steel Beam top flange, and together with floor concrete casting, it is weaker that there are rigidity for top flange, steel
The shortcomings of plate web is easily recessed, and building processing is difficult.
Invention content
The invention solves existing technology Shaped Steel beams of concrete concrete and amount of reinforcement are big, the big problem of manufacture difficulty,
And the problem of combination beam rigidity of girder steel top flange and Combined concrete is weaker, and web is easily recessed, provide the present invention's thus
A kind of double steel plate Combination beam of steel and concrete, this combination beam are saved with material, and pressure-bearing is high with shearing strength, are made easy for construction.
To solve the above problems, its special character of the technical solution adopted by the present invention is provided with upper steel plate and lower steel plate, institute
It states and is welded with cuff-like shearing resistance muscle between upper steel plate and lower steel plate, vertical portion and the upper steel plate and the lower steel of the cuff-like shearing resistance muscle
Plate is vertical, and a distance H is moved in the relatively upper and lower intermarginal line of steel plate side of vertical portion outer rim of the cuff-like shearing resistance muscle, described
Cuff-like shearing resistance muscle is arranged along upper and lower steel plate length direction uniform intervals, and concrete is disposed between the upper steel plate and lower steel plate,
So that the cuff-like shearing resistance muscle is at the state being embedded in concrete.
The cuff-like shearing resistance muscle can be stirrup, can also be pairs of symmetrically arranged arch muscle.
It further illustrates the present invention with reference to the accompanying drawings and detailed description.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is a kind of A-A sectional views of Fig. 1, has stirrup；
Fig. 3 is another A-A sectional view of Fig. 1, has pairs of symmetrically arranged arch muscle.
Specific implementation mode
Example one
A kind of double steel plate Combination beam of steel and concrete is equipped with upper steel plate 1 and lower steel plate 4, upper steel plate 1 is under referring to Fig. 1,2
Stirrup 301 is welded between steel plate 4, the vertical portion of stirrup 301 is vertical with upper steel plate 1 and lower steel plate 4, stirrup 301 it is vertical
For part outer rim with respect to a distance H is moved in line between upper steel plate 1,4 lateral margin of lower steel plate, stirrup 301 is equal along upper and lower steel plate length direction
Even arranged for interval is disposed with concrete 2 between upper steel plate 1 and lower steel plate 4, so that stirrup 301 is at the shape being embedded in concrete 2
State.
Concrete 2 can pour together in building-site and upper and lower steel plate, can also be poured in factory and upper and lower steel plate
It builds together, forms entirety, transport to building site.
The present invention is advantageous in that：
1. upper and lower steel plate bears the Moment of beam, stirrup and concrete bear to shear, while playing steel ductility and mixing
The advantage of solidifying soil durability.
2. eliminating the web among traditional girder steel, concrete prevents the generation of the local stability of steel beam flange, substantially
Degree reduces the dosage of steel.
3. increasing than the rigidity of clean steel beam more.
4. because eliminating the web among traditional girder steel, therefore reducing the antifouling paint at steel beam flange and fireproof coating
Dosage eliminates antifouling paint and fireproof coating dosage at steel beam web plate.
5. reducing the plank sheathing dosage in beam bottom portion, construction cost is reduced.
6. combination beam is during factory manufacturing, situ wet operation can be reduced, speed of application is fast.
Example two
This example double steel plate Combination beam of steel and concrete is different from being with symmetrically arranged in pairs for example referring to Fig. 1,3
Arch muscle 302 substitutes stirrup 301, other constructions are identical as upper example.
Claims (2)
1. a kind of double steel plate Combination beam of steel and concrete, it is characterized in that being equipped with upper steel plate (1) and lower steel plate (4), the upper steel plate
Cuff-like shearing resistance muscle is welded between lower steel plate, the vertical portion of the cuff-like shearing resistance muscle is vertical with the upper steel plate and lower steel plate,
And a distance H, the cuff-like shearing resistance are moved in the relatively upper and lower intermarginal line of steel plate side of vertical portion outer rim of the cuff-like shearing resistance muscle
Muscle is arranged along upper and lower steel plate length direction uniform intervals, and concrete (2) is disposed between the upper steel plate and lower steel plate, so that
The cuff-like shearing resistance muscle is at the state being embedded in concrete.
2. combination beam as described in claim 1, it is characterized in that the cuff-like shearing resistance muscle is stirrup (301) or is symmetrical arranged in pairs
Arch muscle (302).
