Abstract

The utility model discloses a kind of FRP bow member, comprise some the main muscle of the arch FRP be parallel to each other, be equipped with the secondary muscle of folding shape FRP between arbitrary neighborhood two main muscle of arch FRP, the two ends of the main muscle of every bar arch FRP are equipped with end junction plate.The utility model bow member body adopts FRP material, and what take full advantage of FRP material can cutting, and bow member body, without the need to dismounting, facilitates shield machine construction, decreases duration and potential safety hazard.

Description

A kind of FRP bow member

Technical field

The utility model relates to a kind of constructing tunnel device, especially a kind of FRP (Fiber Reinforced Plastics: fibre-reinforced plastics) bow member.

Background technology

In modern industry, people need steel bow member when carrying out constructing tunnel, play stable working face effect, some special occasions, for not affecting follow-up shield machine construction, need remove metal bow member, but metal bow member is not easily removed, and remove operation poor stability, efficiency is low, easily causes construction delay, construction safety hidden danger.

Summary of the invention

Goal of the invention: the purpose of this utility model is for prior art problem, provides a kind of without the need to dismounting, the FRP bow member facilitating shield machine construction.

To achieve these goals, the utility model have employed following technical scheme: a kind of FRP bow member, comprise some the main muscle of the arch FRP be parallel to each other, be equipped with the secondary muscle of folding shape FRP between arbitrary neighborhood two main muscle of arch FRP, the two ends of the main muscle of arch FRP are provided with end junction plate.

In the utility model, preferably, fixed by silvalin colligation between the secondary muscle of described folding shape FRP and the main muscle of arch FRP.

In the utility model, preferably, fixed by silvalin colligation between described end junction plate and the main muscle of arch FRP.

Beneficial effect: the utility model bow member body adopts FRP material, what take full advantage of FRP material can cutting, and bow member body, without the need to dismounting, facilitates shield machine construction, decreases duration and potential safety hazard.

Detailed description of the invention:

Below in conjunction with accompanying drawing the utility model done and further explain.

Embodiment one

As illustrated in fig. 1 and 2, FRP bow member of the present utility model comprises two main muscle 1 of the arch FRP be parallel to each other, article two, between the main muscle 1 of arch FRP, be provided with the secondary muscle 2 of folding shape FRP, the two ends of the main muscle 1 of arch FRP are provided with end junction plate 3, between the secondary muscle 2 of folding shape FRP and the main muscle 1 of arch FRP, and all fixed by silvalin 4 colligation between end junction plate 3 and the main muscle 1 of arch FRP.

During production, first silvalin 4 colligation by saturated ring epoxy resins in advance of main for arch FRP muscle 1 and the secondary muscle 2 of folding shape FRP is fixed, then arch FRP main muscle 1 two ends and end junction plate 3 are also fixed by silvalin 4 colligation of saturated ring epoxy resins in advance, and namely silvalin 4 forms full FRP structure bow member after solidifying.

Embodiment two

As shown in Figures 3 and 4, embodiment two is with the difference of embodiment one, and the main muscle 1 of arch FRP is three, and the spacing homogeneous phase etc. of any two main muscle of arch FRP.

The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
