Description
Technical field
The invention belongs to Structures Reinforced Technique fields, and in particular to it is a kind of with carbon fibre reinforced composite reinforce
Making circular hole Honeycomb Beam.
Background technique
Honeycomb Beam is a kind of steel member proposed according to girder steel mechanical characteristic, refers to web with series of rules hole
I-shape steel beam.For Honeycomb Beam as a kind of structure novel, unique steel structure girder, itself also has many merits.Firstly, honeycomb
Hole on beam can be effectively increased the space of interlayer, be improved the utilization efficiency in section with crossing pipeline and electric wire.Its
Secondary, Honeycomb Beam saves paint and mounting cost 15%-35%, significantly reduces and be built into than solid web girder saving steel 25%-30%
This, is to solve high one of the important channel of China's steel building cost.Meanwhile Honeycomb Beam also has raising section mechanical property
The advantages that energy, simple beautiful and production.
But since aperture of the Honeycomb Beam on web changes transmitting of the power in steel beam web plate, result in Honeycomb Beam
When loaded, web holes edge is easy stress and concentrates and buckling occurs and leads to local buckling, eventually leads to general loss and holds
Power is carried, how to solve the problems, such as that Honeycomb Beam hole edge is easy local buckling and improves the bearing capacity of Honeycomb Beam, is many at present
Hot spot of the scholar in research.
Summary of the invention
It is an object of the present invention to provide a kind of making circular hole Honeycomb Beams reinforced with carbon fibre reinforced composite, solve
Honeycomb Beam hole edge is easy the problem of local buckling and improves the bearing capacity of Honeycomb Beam, while improving it to a certain extent
Shock resistance, anti-fatigue performance, corrosion resistance.
The technical solution adopted in the present invention: a kind of making circular hole Honeycomb Beam reinforced with carbon fibre reinforced composite,
The making circular hole Honeycomb Beam is the i-shape steel beam with several ribbed stiffeners, and a circle is opened among every two panels ribbed stiffener
Circular ring shape carbon fibre reinforced composite is pasted in the web two sides of all rounded opening edges in hole, and respectively on a round hole left side
Upper, lower-left, upper right, the region of bottom right four, tangent mode pastes bar shaped carbon fibre reinforced composite with the round hole.
Preferably, the bar shaped carbon fibre reinforced composite with Honeycomb Beam angle at 45 °.
The circular ring shape carbon fibre composite will be cut through large stretch of carbon fibre composite, and annulus inner circle is straight
Diameter is circular opening diameter, and annular width is 1/5-1/3 circle bore dia.
The every length of a film 1/2-3/4 circle bore dia of bar shaped carbon fibre composite, wide 1/5-1/3 circle bore dia.
Pasting adhesive used is and the matching used epoxyn of carbon fibre reinforced composite.
The carbon fibre composite is carbon cloth.
The beneficial effects of the present invention are: the carbon cloth intensity used it is high, it is corrosion-resistant, from heavy and light, small in size, stress is clear
It is good with clear and reinforcing effect, while simple and convenient of constructing, the general advantage such as the construction period is short.The present invention is dexterously in Honeycomb Beam
Hole upper left, lower-left, upper right, the angle of bottom right four reinforced by carbon fibre reinforced composite, can be well solved bee
Nest beam hole edge is easy the problem of local buckling and improves the bearing capacity of Honeycomb Beam, while improving its anti-impact to a certain extent
Hit performance, anti-fatigue performance, corrosion resistance.
Compared with traditional steel construction reinforcement such as passes through the methods of bolt or welding, the present invention reinforces method and does not need volume
Outer drilling, avoids end weld fatigue rupture, drilling causes member section to weaken, and generates the possibility etc. that new stress is concentrated.

Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Carbon cloth as shown in Figure 1, should size first as required make.Of the invention is carbon fiber composite material reinforced
Steel Castellated Beams include making circular hole Honeycomb Beam 1-1, bar shaped carbon cloth 1-2 and circular ring shape carbon cloth 1-3.
The making circular hole Honeycomb Beam, is i-shape steel beam, and a circular hole is opened among every two panels ribbed stiffener.Two kinds of carbon
Fiber cloth should cut to obtain in a piece of big carbon cloth through mode described in Fig. 1, can save carbon fiber cloth material in this way.Such as figure
Shown in 1, circular diameter is the diameter of circular opening in annulus, and annular width is 1/5-1/3 circle bore dia.The bar shaped carbon fiber
The every length of a film 1/2-3/4 circle bore dia of composite material, wide 1/5-1/3 circle bore dia.
As in Figure 2-4, circular ring shape carbon cloth 1-3 with carbon fiber glue is first pasted onto Honeycomb Beam 1-1 each is opened
The edge in hole, web both sides are each a piece of.The globality that can increase steel stress around hole in this way, improves stress raisers
Problem；It is each again in the mode tangent with circular hole at the every upper left circular ring shape carbon cloth 1-3, lower-left, upper right, the angle of bottom right four again
It pastes the phenomenon that a piece of bar shaped carbon cloth 1-2 is further reinforced, can pointedly be improved local buckling around hole in this way and fills
Divide the material property using carbon cloth.Girder steel bearing capacity after reinforcing is obviously improved, and anti-fatigue performance, shock resistance
Different degrees of improvement is all obtained, experiment shows that Honeycomb Beam local buckling phenomenon is frequently experienced in hole upper left, lower-left, the right side
The upper, angle of bottom right four (specific location refers to Fig. 2,3,4).
As described above, the present invention can be better realized.
Embodiment of the present invention are not limited by the above embodiments, other are any without departing from Spirit Essence of the invention
With changes, modifications, substitutions, combinations, simplifications made under principle, equivalent substitute mode should be, be included in of the invention
Within protection scope.
