The specific embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Fig. 1-6:
Built-in steel strand composite material waveform anticollision barrier of the present invention, it comprises composite material corrugated guardrail 1, composite material corrugated guardrail 1 adopts glass fiber and vinylite by the preparation of vacuum introducing technology, the interior employing pre-tensioning system of composite material corrugated guardrail 1 arranges two bundle steel strand 2, steel strand 2 places set up composite material thickening part 3, steel strand 2 ends arrange stainless steel termination clip 5, be connected by bolt 6 between composite material corrugated guardrail 1 and composite material corrugated guardrail 1, be connected by connecting hoop 7 between steel strand 2 and steel strand 2.
Built-in steel strand composite material waveform anticollision barrier of the present invention, it comprises composite material corrugated guardrail 1, composite material corrugated guardrail 1 adopts glass fiber and vinylite by the preparation of vacuum introducing technology, the pre-buried 4 plastics preserved pipelines 4 of the interior employing post stretching of composite material corrugated guardrail 1 arrange four bundle steel strand 2, steel strand 2 places set up composite material thickening part 3, steel strand 2 ends arrange stainless steel termination clip 5, be connected by bolt 6 between composite material corrugated guardrail 1 and composite material corrugated guardrail 1, be connected by connecting hoop 7 between steel strand 2 and steel strand 2.
In above-mentioned two embodiment, the preparation method of built-in steel strand composite material waveform anticollision barrier mainly adopts the vacuum introducing technology, and the below settles steel strand as example take post stretching:
A, first make the mould of built-in steel strand composite material waveform anticollision barrier of steel or wood;
B, with multi-layer fiber cloth (comprising: single shaft to, twin shaft to or multiaxis to carbon fiber, glass fiber, aramid fiber and hybridization cloth etc.) be layed on mould, pre-buried preserved pipeline 4 on the position that requires re-lays vacuum bag;
C, by vacuum guiding and forming technique, resin (comprising: unsaturated polyester (UP), vinylite, epoxy resin, phenolic resins etc.) is circulated in vacuum bag; With resin solidification, after the resin solidification moulding, take out member at normal temperatures and pressures, namely form composite material corrugated guardrail 1;
D, penetrate steel strand 2 in composite material corrugated guardrail 1 preserved pipeline 4, the termination, two ends adopts termination clip 5 to form closed circle, and composite material corrugated guardrail 1 and steel strand 2 are combined as a whole;
