Abstract
The utility model discloses a corrosion-resisting high-strength composite grouting column which comprises an inner-layer reinforced concrete column, outer-layer reinforced concrete, and a steel tube between the inner-layer reinforced concrete column and the outer-layer reinforced concrete. Steel bars in the inner-layer reinforced concrete column comprise longitudinal steel bars and stirrups. The stirrups are arranged along the radial direction of the steel tube, are sleeved outside the longitudinal steel bars, and enable the longitudinal steel bars to be connected together. A layer of poly vinyl chloride (PVC) tube is wrapped outside the outer-layer reinforced concrete. The corrosion-resisting high-strength composite grouting column has the advantages that loading capacity is strong, and meanwhile corrosion resistance is good.
Description
Technical field
The utility model relates to a kind of grouting post, is specifically related to a kind of anti-corrosion and high strength compound grouting post.
Background technology
The grouting post can be used in a lot of places as supporter, arrives the supporter of bridge greatly, little supporter to small building.The grouting post is in the middle of practical applications, and role is vital, and it plays a part pressure-bearing, is the main support body of engineering construction.Because the environment that building construction is the people lives, and it not only requires it to keep attractive in appearance for a long time, and its bearing strength is also had certain requirement when being used in the building structure.Simple concrete anticorrosion ability is not too strong, if want long-term maintenance, will be regular safeguard that and regular maintenance has just increased the cost of operating period.
The utility model content
The utility model has overcome the deficiency of prior art, and a kind of anti-corrosion and high strength compound grouting post is provided, and this utility model not only bearing capacity is strong, and good resistance to corrosion is arranged.
For solving above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of anti-corrosion and high strength compound grouting post; It comprises the steel pipe between internal layer reinforced concrete post, outer concrete and internal layer reinforced concrete post and the outer concrete, and the reinforcing bar in the described internal layer reinforced concrete post has longitudinal reinforcement and stirrup, and described longitudinal reinforcement has four at least; And axially evenly distributed along steel pipe; Described stirrup has four at least, and along radially the arranging of steel pipe, and it is outer and longitudinal reinforcement connected together to be enclosed within longitudinal reinforcement; Described outer concrete is wrapped with one deck pvc pipe, and described internal layer reinforced concrete post, steel pipe are identical with the pvc pipe height.Than higher, it is attractive in appearance to want the maintenance that it can be permanent to the requirement of U.S.A for the modern, and outermost layer just must have erosion-resisting material.PVC is a kind of polymeric material of vinyl, and its material is a kind of amorphism material.The PVC material often adds stabilizing agent, sliding agent, secondary process agent, colorant, impact modifier and other additive in actual use.Have low flammability, high strength, gasproof marquis variability and good geometrical stability.PVC has very strong resistance to oxidant, reducing agent and strong acid, so the PVC material is installed on outermost layer, can well play this effect.Constructional materials not only requires it corrosion-resistant, but also necessary strong, the anti-pull ability of bearing capacity is strong.Concrete is one of topmost bearing structure, in the internal layer reinforced concrete post longitudinal reinforcement is arranged, and has further strengthened its bearing capacity.
Technical scheme further is:
The thickness of described outer concrete is less than or equal to 1/10 of the compound concrete bridge pier column structure radius of described high strength.The main bearing structure of anti-corrosion and high strength compound grouting post is the internal layer reinforced concrete post, and outer concrete also can play the pressure-bearing effect, but it mainly is the protection steel pipe, so be difficult for too thick.
Described pvc pipe (5) is a hard PVC.PVC can be divided into hard PVC and soft pvc.Wherein soft pvc generally is used for the top layer of floor, ceiling and leather, but owing to contain softening agent (this also is the difference of soft pvc and hard PVC) in the soft pvc, becomes fragile easily, is difficult for preserving.Hard PVC does not contain softening agent, so pliability is good, easy-formation, be difficult for crisp, nontoxic pollution-free, the holding time is long.
Compared with prior art, the beneficial effect of the utility model is:
1, the longitudinal reinforcement of the utility model internal layer reinforced concrete post increased anti-corrosion and high strength compound grouting post bearing strength;
2, the internal layer reinforced concrete post of the utility model has steel pipe outward, has strengthened the anti-pull ability of anti-corrosion and high strength compound grouting post;
3, the coated outside of the utility model one deck pvc pipe, strengthened its resistance to corrosion, can make the original apperance of its permanent maintenance, say the cost that can save periodic maintenance to a certain extent.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Label among the figure is: 1, longitudinal reinforcement; 2, steel pipe; 3, internal layer reinforced concrete post; 4, outer concrete; 5, pvc pipe; 6, stirrup.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.The embodiment of the utility model includes but not limited to the following example.
Embodiment
A kind of anti-corrosion and high strength compound grouting post shown in Fig. 1; It comprises the steel pipe 2 between internal layer reinforced concrete post 3, outer concrete 4 and internal layer reinforced concrete post 3 and the outer concrete 4, and the reinforcing bar in the internal layer reinforced concrete post 3 has longitudinal reinforcement 1 and stirrup 6, and longitudinal reinforcement 1 has four at least; And axially evenly distributed along steel pipe 2; Stirrup 5 has four at least, and along radially the arranging of steel pipe 2, and it is outer and longitudinal reinforcement 1 connected together to be enclosed within longitudinal reinforcement 1; Outer concrete 4 is wrapped with one deck pvc pipe 5, and internal layer reinforced concrete post 3, steel pipe 2 and pvc pipe 5 are highly identical.The thickness of outer concrete 4 is less than or equal to 1/10 of the compound concrete bridge pier column structure radius of described high strength.Pvc pipe 5 is hard PVCs.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
