Abstract
The utility model discloses a steel reinforced concrete mixing structure for an FRP (Fiber Reinforce Plastic) pipe. The steel reinforced concrete mixing structure is formed by pouring the FRP pipe and an inner steel rib in a mixed manner; and the FRP pipe is superposed with the geometric shape of the cross section of the inner steel rib. The steel reinforced concrete mixing structure has the advantages of good durability, convenience for construction, high carrying capacity and strong anti-seismic capacity, wherein under the restriction of an outer FRP pipe, the durability of the steel reinforced concrete structure is improved owing to the fact that the FRP material has better corrosion resistances to atmosphere, water, various oils and solvents, as well as acids, alkalis and salts with a general concentration; the FRP pipe and the steel rib itself are templates which resist lateral pressure, so that the template construction can be eliminated in the process of pouring concrete, therefore the construction installation technology is simplified, the construction land is reduced and the construction period is shortened; the steel rib is designed in the concrete, and the steel reinforced concrete is restricted by the FRP pipe, so that a large hooping force is provided, therefore the carrying capacity and anti-seismic capacity of the steel reinforced concrete mixing structure are improved; and the steel reinforced concrete mixing structure is especially suitable for anti-seismic capacity design in meizoseismal areas.
Description
Technical field
The utility model relates to a kind of steel reinforced concrete combination construction, particularly a kind of steel reinforced concrete combination construction of FRP pipe.
Background technology
Steel reinforced concrete structure is meant main configuration reinforcing bar in the cross section; And be furnished with certain longitudinal reinforcement and lateral tie; The embedded structure of concreting, because it has advantages such as supporting capacity height, anti-seismic performance is good, refractoriness is good, therefore extensive use in highrise building, heavy structure.But; Also there are some shortcomings in steel reinforced concrete structure, distinct issues be construct more numerous and diverse, and in long-term use owing to receive the influence of environment and incidental load effect; Its safety, durability and applicability constantly reduce, and shorten its application life greatly.
The utility model content
The purpose of the utility model provides a kind of steel reinforced concrete combination construction that can be used for the FRP pipe of strengthening and rebuilding engineering and particular surroundings.
The technical scheme of the utility model is: the steel reinforced concrete combination construction of a kind of FRP pipe, this structure are mixed the FRP pipe to build with interior reinforcing bar by concrete and form, and said FRP manages and the geometric form coincidence in interior reinforcing bar cross section.
Reinforcing bar is cross reinforcing bar or I-shaped reinforcing bar or T-steel bone or pipe reinforcing bar or square tube reinforcing bar in said.
The beneficial effect of the utility model is: 1, good endurance.FRP pipe constraint outside down, the durability of steel reinforced concrete structure is improved, because the FRP material all has resistance to corrosion preferably to acid, alkali, salt and multiple oils and the solvent of atmosphere, water and general concentration.
2, easy construction.FRP pipe and reinforcing bar itself are the templates of anti-side pressure, when placing of concrete, can save the construction of template, simplify installation technology, reduce construction land tenure and reduction of erection time.
3, supporting capacity is high, shock resistance is strong.Reinforcing bar is located in the concrete, and FRP pipe retrains steel reinforced concrete again, and very big clamping force is provided, and has therefore improved bearing capacity, the anti-seismic performance of structure, is particularly useful for the meizoseismal area seismic design.

The specific embodiment
Embodiment 1 is as shown in Figure 1: the steel reinforced concrete combination construction of a kind of FRP pipe, this structure are mixed FRP pipe 1 to build with interior reinforcing bar 3 by concrete 2 and form the geometric form coincidence in said FRP pipe 1 and interior reinforcing bar 3 cross sections.
Reinforcing bar 3 is the cross reinforcing bar in said.
Earlier with behind interior reinforcing bar, longitudinal reinforcement and stirrup colligation, the installation in position, and then outer FRP pipe is installed, is guaranteed that outer FRP manages and the geometric centroid coincidence in interior reinforcing bar cross section, at last outside FRP manage and interior reinforcing bar between placing of concrete.
Embodiment 4 is as shown in Figure 4: a kind of steel reinforced concrete combination construction of FRP pipe, embodiment are with embodiment 1, and reinforcing bar 3 is the I-shaped reinforcing bar in it.
Embodiment 5 is as shown in Figure 5: a kind of steel reinforced concrete combination construction of FRP pipe, embodiment are with embodiment 1, and reinforcing bar 3 is the T-steel bone in it.
