Abstract
The utility model discloses an FRP (fiberglass reinforced plastics) road barrier which comprises transverse tubes, inner connecting pieces and isolation piers. The transverse tubes thread through the tube holes on the isolation piers to be actively fixed; and the inner connecting pieces are arranged in the abutting joint of the transverse tubes. The FRP road barrier overcomes the disadvantage that metal transverse tubes consume metal resource and are heavy and easy to be stolen and sold, and the disadvantage that the PVC tubes droop and are easy to age and crack. Meanwhile, the inner connecting pieces are nice-looking and particularly have certain strength and long service life.
Description
Technical field
The utility model belongs to the fence group in International Patent Classification (IPC), i.e. E04M, the particularly spacer bar used of road.
Background technology
The spacer bar of road is used metal tube the earliest, because heaviness is also easily stolen, is replaced by pvc pipe gradually, connects with external piece between the cross bar.Pvc pipe is easily by ultraviolet light and aging and cracked, and in about 1.5 years of life-span, simultaneously softer, vicat softening temperature is 72-82 ℃, and bending strength 105Mpa often produces saggingly, and in 4 meters at interval, flexural deformation reaches more than the 100mm.Since use external piece, therefore not too attractive in appearance.One of artificial domestic glass fiber reinforced plastics product manufacturing enterprise the earliest of application develops the spacer bar that can overcome an above-mentioned difficult problem according to society need, by retrieval, fails to find the new departure that overcomes an above-mentioned difficult problem.Here said " glass fiber reinforced plastic " is known by the domestic public, " glass fiber reinforced plastics " that external address is known for the only a few talent.
The utility model content
The purpose of this utility model provides a kind of glass fiber reinforced plastic road and isolates railing, and it has certain intensity, is difficult for wearing out, is difficult for being stolen and sold.It is as follows to disclose new technical scheme:
A kind of glass fiber reinforced plastic road is isolated railing, comprises transverse tube, interior fitting and hard shoulder, and it is active fixing to it is characterized in that transverse tube passes behind the pore of hard shoulder, and the joint between the said transverse tube is built-in with interior fitting.
Press the road isolation railing that such scheme is made, certain intensity is arranged, bending strength reaches 450Mpa, and is ageing-resistant, and in about 20 years of life-span, not sagging, the flexural deformation at 4 meters intervals is 5-10mm, is difficult for discovering, and is difficult for being stolen and sold.Compare with metal tube, saved metals resources.It is easily installed, and since in connect, therefore more attractive in appearance.

Fig. 2 is the profile of transverse tube joint among Fig. 1.
Fig. 3 is the schematic diagram of prior art.
Fig. 4 is the joint profile of Fig. 3.
Wherein: 1, hard shoulder 2, transverse tube 3, interior fitting 4, external piece
The specific embodiment
A kind of glass fiber reinforced plastic road is isolated railing, comprises transverse tube 2, interior fitting 3 and hard shoulder 1, it is characterized in that transverse tube 2 passes active the fixing of pore of hard shoulder 1, the joint between the said transverse tube 2, fitting 3 in being built-in with.
Fitting 3 is a short tube in said, merges fixing with transverse tube 2 close-fittings.Transverse tube 2 is one or each one up and down, and the pore on the hard shoulder 1 should be 1 or each one up and down mutually.
The preparation of glass fiber reinforced plastic is cured as mature technology.What can innovate is component and the assembly relation between them.Here said hard shoulder 1 is on an empty stomach, and not only carrying and installation is convenient, also reduces cost in order to economize on resources simultaneously.
