Abstract

An H-section steel reinforced concrete beam has the advantages of good fireproof performance, good stability, strong stiffness, no distortion, small section and non-interference of the floor height of the building. Block plates (2) are welded and connected at the space extending downward from the upper wing edge of the H-section steel (1) and the space extending upward from the lower wing edge of the H-section steel with the space; a vertical steel (3) is positioned in the belly part between the upper wing edge and the lower wing edge of the H-section steel; hoping steels (4) are interwoven on the vertical steel with the space; the belly part between the upper edge and the lower edge of the H-section steel is filled with concrete(5); and a steel wire screen (6) is compounded under the lower wing edge of the H-section steel. The utility model is fit for the floor beam of the high rise steel structure.

Description

H shaped steel belly concrete combination beam

Technical field

The utility model relates to the building floor beam.

Background technology

At present, many high-rise steel structure floor beam extensively adopts girder steel or girder with rolled steel section en cased in concrete, and this steel reinforced concrete beam is meant the beam that disposes shaped steel and reinforcing bar in the concrete.Though girder steel has the advantage that section is little, easy for installation, speed of application is fast, girder with rolled steel section en cased in concrete has that rigidity is big, fireproof performance good, part and the good advantage of resistance to overturning, and respectively there is its weak point in these two kinds of beams, mainly are:

1, girder steel:

1. the shape of H section steel beam influence building is attractive in appearance, and the girder steel of other form is processed numerous Xu, the expense height;

2. fireproof performance is poor, and fire protection expense is with high;

3. part and resistance to overturning are poor;

4. rigidity is little, and distortion is big.

2, girder with rolled steel section en cased in concrete:

1. the numerous Xu of assembling reinforcement, speed of application is slow;

2. with steel connected node complexity, difficulty of construction is big, the expense height;

3. section is big, influence building floor height;

4. owing to be protected the layer thickness influence, the shaped steel height is little, and economic effect is poor.

Summary of the invention

The utility model will solve the problem that there are above-mentioned weak point in girder steel and girder with rolled steel section en cased in concrete in the prior art, H shaped steel belly concrete combination beam of the present utility model is provided for this reason, this compound beam has the plurality of advantages of girder steel and girder with rolled steel section en cased in concrete concurrently, and can eliminate girder steel and there is weak point separately in girder with rolled steel section en cased in concrete.

For addressing the above problem, its special character of the technical solution adopted in the utility model is that weldering is connected with the concrete fixture on H shaped steel, is filled with concrete in the top flange of H shaped steel and the belly between the bottom flange.

Its outer wall of described concrete should be concordant with the outside of described top flange and bottom flange.

Described concrete fixture can be linked to the top flange and extend downwards with bottom flange and upwardly extending baffle plate.Baffle interval is provided with, and concrete is played fixation.

Described concrete fixture also can be the connector that is linked to web.Connector is provided with at interval, and concrete is played fixation.

The utility model can be connected with fixedly muscle between the baffle plate on the upper and lower edge of a wing of H shaped steel.

The utility model can be provided with vertical muscle at the belly between top flange and the bottom flange, and the compartment of terrain links on the vertical muscle stirrup.Vertical muscle is general parallel with H shaped steel.

Can below the bottom flange of described H shaped steel, be compounded with gauze wire cloth.But be compound in below the bottom flange this gauze wire cloth semi-surrounding and both sides and can be above the bottom flange in to extension one distance.The effect of gauze wire cloth is, plasters easily in the outside, bottom flange.If when having parallel with it body of wall below the combination Liangqi of the present utility model, the bottom flange is embedded within the walls, then need not the clad steel silk screen.

The utility model is owing to weldering on H shaped steel is connected with the concrete fixture, be filled with concrete in the top flange of H shaped steel and the belly between the bottom flange, and outer walls of concrete can be concordant with the outside of described top flange and bottom flange, so the utility model can make the web of H shaped steel and upper and lower edge of a wing inner face compound by concrete, also plaster easily in below the bottom flange and side, thereby raising fireproof performance, and with respect to H shaped steel, the utility model face shaping is good, part and resistance to overturning height, rigidity is big, is out of shape little; With respect to girder with rolled steel section en cased in concrete, the utility model can avoid numerous Xu assembling reinforcement, and easy construction and speed are fast, save operating expenses, and section is little, does not influence the building floor height, good economical benefit.Be compounded with the utility model of gauze wire cloth in H shaped steel bottom flange, easily at the bottom flange exterior rendering.
