Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The use of the terms "upper", "lower", "left", "right" and the like in the present invention is for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1 is a schematic view of a combination of ribs and carbon fiber cloth provided by the present invention; fig. 2 is a schematic structural view of an externally wrapped fiber cloth composite rib provided by the present invention; fig. 3 is a cross-sectional view of a fiber cloth covered composite rib provided by the present invention. Referring to fig. 1-3, the composite material rib comprises ribs 1 and carbon fiber cloth 2; one end of each rib 1 is provided with a groove 3, and the other end of each rib is provided with a lug 4 matched with the groove 3; the carbon fiber cloth 2 is connected on the outer surface of the rib 1.
It should be noted that the composite material bar in the prior art has poor shear resistance and low elastic modulus, which causes the defects of poor shear resistance of structural members such as beams and columns taking the bar as a main bar, too large deformation and cracks, easy injury to people due to surface burrs, and the like, thereby limiting the wider application in engineering.
Therefore, in the utility model, the carbon fiber cloth 2 is connected on the surface of the rib 1. The two are formed into a new composite rib. The novel composite material rib formed by combination not only can greatly improve the bearing capacity and the elastic modulus of the rib, but also can improve the shearing resistance and the toughness of the rib, reduces burrs on the surface of the rib and is easy to process manually. And can effectively avoid corrosion in a corrosive environment, and greatly block the corrosive action of the corrosive environment such as the ocean on the main bar.
Secondly, in the actual life, the condition that the rib is too short can appear, needs the staff to overlap two ribs partly, then fixes through the steel wire, and is more troublesome, and fixes insecurely. Therefore, the utility model discloses in wherein one end at rib 1 has set up recess 3, the other end set up with recess 3 assorted lug 4, if need connect two ribs 1, can connect in the lug 4 of one of them rib 1 inserts recess 3 of another rib 1. So that it is more convenient to connect the two ribs 1. The ribs 1 may be glass fiber ribs or the like.
Further, the carbon fiber cloth 2 is adhered to the outer surface of the rib 1 through a strong glue layer 3. The carbon fiber cloth 2 is adhered to the outer surface of the rib 1 through the super glue layer 3, so that the carbon fiber cloth 2 can be adhered more firmly.
In addition, the strong glue layer 3 can be a double-component modified epoxy resin adhesive for adhering carbon fiber glue, the adhesive strength is high, the operation is convenient, the adaptability to carbon fibers is good, and the permeability is strong. The aging resistance, the water resistance and the chemical corrosion resistance are excellent. The curing condition is loose, the proportioning range is wide, and the operable time is long. The adhesive has complete varieties and is a curable winter structural adhesive under the condition of low temperature (-5 to-10 ℃), thereby ensuring normal construction in winter.
Further, the projection 4 and the groove 3 are both cylindrical.
Further, the outer surface of the projection 4 and the inner surface of the recess 3 are provided with mutually matching threads 6. It should be noted that, the matching screw threads 6 are provided on the cylindrical protrusion 4 and the groove 3, so that the two ribs 1 can be connected more firmly.
Further, the cross section of the composite material rib is circular. The carbon fiber cloth 2 is regularly connected to the surface of the rib 1, so that the shear resistance and toughness of the rib 1 are enhanced without changing the original shape. In addition, in practical application, the method can be adjusted according to the actual requirements of engineering and the requirements of construction reinforcement.
Further, the thickness of the carbon fiber cloth 2 was 0.167 mm. It should be noted that the carbon fiber cloth can provide two thicknesses: 0.111mm (200g) and 0.167mm (300 g). The strength of the carbon fiber cloth with the thickness of 0.167mm can reach 8 times of that of steel, and exceeds 4000 MPa.
In addition, the carbon fiber cloth 2 may be carbon fiber woven cloth, woven carbon fiber cloth, knitted carbon fiber cloth, woven carbon fiber cloth, carbon fiber prepreg cloth, carbon fiber non-woven cloth, or the like.
Further, the carbon fiber cloth 2 has 1 to 3 layers.
The utility model discloses a complete work flow can be: the inner layer of the carbon fiber cloth 2 is coated with the strong glue layer 5, the surface of the rib 1 is coated with the strong glue layer 5, and then the carbon fiber cloth 2 and the rib 1 are combined into a whole through the adhesion effect of the strong glue layer 5 to form a novel composite material rib. If two ribs 1 need to be connected, the convex block 4 of one rib 1 can be inserted into the groove 3 of the other rib 1 and screwed tightly through the thread 6.
It is worth explaining, in the utility model discloses, combine carbon cloth and rib as an organic whole through the powerful glue film, form a outsourcing fibre cloth combined material muscle to make this combined material muscle have advantages such as high tensile strength, high modulus, high shear capacity, have very strong corrosion resisting capacity simultaneously.
