An HDPE tube steel-reinforced concrete hybrid structure is formed by mixing HDPE tubes with concrete and longitudinally stressed steel bars and stirrups arranged around the inner steel frame. The beneficial effects of the utility model are: good anti-seismic performance and high bearing capacity. Under the combined constraints of the outer HDPE pipe and the inner steel frame, the bearing capacity of the concrete column is improved, and the ductility and earthquake resistance are improved, so that the cross-sectional size of the column is reduced and the usable area is increased. Construction is convenient. The HDPE pipe is a formwork resistant to lateral pressure. When pouring concrete, the construction of the formwork can be omitted, and it can adapt to the advanced pumping concrete technology. Therefore, the construction and installation process can be simplified and the construction period can be shortened. The HDPE pipes and steel frames in the structure act as constraints on the concrete respectively, improving the structure's seismic performance and bearing capacity. At the same time, the structure has good durability and fire resistance, which can save steel and speed up construction. It is suitable for large-span , Overload structure.
Description
Technical field
The utility model relates to a kind of steel reinforced concrete combination construction, particularly a kind of HDPE pipe steel reinforced concrete combination construction of HDPE pipe.
Background technology
At present, in highrise building, large-span structure,, adopt high-strength concrete widely, but because there is the shortcoming of ductility difference in high-strength concrete, therefore normal employing steel reinforced concrete structure and encased structures improve in order to reduce the size of column section.Also there are some shortcomings in concrete filled steel tube, and distinct issues are steel pipe easy-to-rusts, and the steel using amount of large diameter steel pipe is bigger than normal, and the processing charges of steel pipe are higher.And steel reinforced concrete structure in long-term use owing to receive the influence of natural environment, and when receiving and the destruction of disasters such as the earthquake that takes place, fire, floods, its safety, durability and applicability can constantly reduce, can shorten its application life.
The utility model content
The purpose of the utility model provides a kind of HDPE pipe steel reinforced concrete combination construction that can be used for strengthening and rebuilding engineering and particular surroundings.
The technical scheme of the utility model is: longitudinal stress reinforcing bar in a kind of HDPE pipe steel reinforced concrete combination construction, this structure are managed HDPE and be configured in by concrete around the reinforcing bar and stirrup mixing are built and are formed.
Reinforcing bar is cross reinforcing bar or I-shaped reinforcing bar or T-steel bone or pipe reinforcing bar or square tube reinforcing bar or lattice reinforcing bar in said.
The invention has the beneficial effects as follows: 1, anti-seismic performance is good, bearing capacity is high.HDPE pipe and the common constraint of interior reinforcing bar outside down, the supporting capacity of concrete column is improved, ductility and shock resistance are improved, thus the sectional dimension of post is reduced, usable floor area obtains increase.
2, easy construction.The HDPE pipe is the template of anti-side pressure, when placing of concrete, can save the construction of template, and can adapt to advanced pump concrete placing technology, therefore, can simplify installation technology, reduction of erection time.
3, pipe of the HDPE in this structure and reinforcing bar play effect of contraction to concrete respectively; Improve structural seismic performance and supporting capacity, this structure has favorable durability and fireproof performance simultaneously, can practice thrift steel; Accelerate advantages such as speed of application, be applicable to greatly stride, heavy structure.

The specific embodiment
Embodiment 1 is as shown in Figure 1: a kind of HDPE pipe steel reinforced concrete combination construction, this structure by concrete with HDPE pipe 1 be configured in longitudinal stress reinforcing bar 3 around the reinforcing bar 4 mix to build with stirrup 2 and form.
Earlier with behind interior reinforcing bar, longitudinal reinforcement and stirrup colligation, the installation in position, and then outer HDPE pipe is installed, is guaranteed that outer HDPE manages and the geometric centroid coincidence in interior reinforcing bar cross section, at last outside HDPE manage and interior reinforcing bar between placing of concrete.
Reinforcing bar 4 is the square tube reinforcing bar in said.
Embodiment 4 is as shown in Figure 4: a kind of HDPE pipe steel reinforced concrete combination construction, and embodiment is with embodiment 1, and reinforcing bar 4 is the I-shaped reinforcing bar in it.
Embodiment 6 is as shown in Figure 6: a kind of HDPE pipe steel reinforced concrete combination construction, and embodiment is with embodiment 1, and reinforcing bar 4 is the lattice reinforcing bar in it.
