Abstract
The utility model discloses a glass reinforced plastic reinforcement circular steel tube and concrete combined structure. The structure comprises a circular steel tube and concrete in the circular steel tube. The structure is characterized in that a layer of glass reinforced plastic is coated on the outer wall of the circular steel tube. The glass reinforced plastic has the characteristics of lightness, high strengthen, corrosion resistance, fatigue resistance and the like, and a layer of glass reinforced plastic is coated on the outer wall of the circular steel tube and concrete combined structure, so that the breaking strength of the circular steel tube and concrete can be increased; the circular steel tube can be protected from being corroded by the outside environment, so that the service life of the circular steel tube and concrete combined structure is prolonged; and the glass reinforced plastic on the outer part of the circular steel tube can be adjusted to be in favorite colors, so that the requirement of attractiveness is satisfied.
Description
Technical field
The utility model is a kind of civil engineering structure, particularly a kind of concrete filled steel tube combining structure that strengthens with glass fiber reinforced plastic.
Background technology
Concrete filled steel tube refers to fill concrete in steel pipe and the member that forms, presses section form different, can be divided into concrete filled steel tube, side, concrete-filled rectangular steel tube and polygon steel pipe concrete etc.Concrete compressive strength is high, but bending resistance is very weak, and the bending resistance of steel, particularly shaped steel is strong, has good elastoplasticity, but when pressurized easy unstability and lose the axial compression resistance ability.And concrete filled steel tube structurally can make concrete be in the side loaded state with both advantages together, and its compressive strength can significantly improve.Due to concrete existence, improved the rigidity of steel pipe simultaneously, both play a role jointly, thereby have improved supporting capacity widely.The steel pipe of different cross section form has very big difference to the effect of contraction of core concrete, and round steel pipe is the most even to the restraint stress distribution of core concrete, and round steel pipe and concrete adhesion stress and frictional force are best.The centrosymmetric characteristics of circular steel tube concrete column section and the equicohesive performance of any direction, (such as the hall of public building, station, garage etc.) not only economy but also reasonable when making it in the works that is applied to any direction traffic flow; When the uncertain geological process of opposing direction, very effective; When being used as the buttress of urban interchange, can all obtain the effect in the best visual field in any direction, and help traffic safety, in pylon structure, the day of circular cross-section rod member is exposed the area minimum to the open air in the open, and front face area is also minimum.But because iron atom is comparatively active metallic atom, round steel pipe easily is subject to the corrosion of various corrosive mediums in atmosphere, and makes the round steel pipe strength decreased.
Glass fiber reinforced plastic is a kind of glass fiber reinforced plastics, and it has the characteristics such as lightweight, high-strength corrosion-resistant erosion, endurance, has been widely used at present, but also has not been used in concrete filled steel tube.
Summary of the invention
In use easily be subject to the corrosion of various corrosive mediums in order to overcome concrete filled steel tube, and the technological deficiency that steel strength is reduced, the utility model provides a kind of glass fiber reinforced plastic to strengthen the concrete filled steel tube combining structure.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of glass fiber reinforced plastic strengthens the concrete filled steel tube combining structure, and it comprises the concrete in round steel pipe and round steel pipe, it is characterized in that, is coated with one deck glass fiber reinforced plastic cladding at the round steel pipe outer wall.
Construction technology of the present utility model is: elder generation's fluid concrete in round steel pipe, and make concrete filled steel tube, then coat one deck glass fiber reinforced plastic at the round steel pipe outer wall, glass fiber reinforced plastic can also be modulated into the color of oneself liking, satisfy requirement attractive in appearance.
The beneficial effects of the utility model are: have the characteristics such as lightweight, high-strength, corrosion-resistant, endurance due to glass fiber reinforced plastic, apply one deck glass fiber reinforced plastic at the mixed combining structure outer wall of round steel, can increase the rupture strength of concrete filled steel tube; Can protect round steel pipe to avoid external environment corrosion, extend concrete filled steel tube application life; The glass fiber reinforced plastic in the round steel pipe outside can be modulated into the color of oneself liking, and satisfies requirement attractive in appearance.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment;
In figure, 1-frp layer, 2-round steel pipe, 3-concrete.
The specific embodiment
As shown in Figure 1, the present embodiment comprises the concrete 3 in round steel pipe 2 and round steel pipe, is coated with as shown in Figure 1 frp layer 1 at round steel pipe 2 outer walls.
During enforcement, first at the inner fluid concrete 3 of round steel pipe 2, make concrete filled steel tube, then at round steel pipe 2 coated with glass fibre reinforced plastics layers 1.
Claims (1)
1. a glass fiber reinforced plastic strengthens the concrete filled steel tube combining structure, and it comprises the concrete in round steel pipe and round steel pipe, it is characterized in that, is coated with one deck glass fiber reinforced plastic at the round steel pipe outer wall.
