Description
Technical field
The present invention relates to a kind of lattice body made of fiber-reinforced synthetic resin, this lattice body made of fiber-reinforced synthetic resin reinforce applicable to the concrete repair of bridge, tunnel, waterfront structure etc. or shield structure vertical shaft among the job practices that arrives of the starting of machine.
Background technology
At present, lattice body made of fiber-reinforced synthetic resin can be used as the uses such as strenthening member that are embedded in the concrete.For example, in shield structure engineering, use vertical shaft, make the shield machine starting, when arriving, lattice body made of fiber-reinforced synthetic resin can be embedded in the concrete sidewall as vertical shaft.In the various job practicess of shield structure engineering, NOMST (Novel MaterialShield-cuttable Tunnel-wall System) job practices is as a rule with this lattice body made of fiber-reinforced synthetic resin and reinforcing bar and usefulness.
As above-mentioned lattice body made of fiber-reinforced synthetic resin, for example, open the spy and to disclose a kind of concrete strengthening member that is embedded in the concrete structure part in the clear 62-153449 communique, it is characterized by, the fiber bundle clathrate that forms intersected with each other that will constitute by several fibers of configuration arranged side by side, each bar fiber with the above-mentioned fiber bundle of resin material looping, and the cross part of above-mentioned fiber bundle forms group of fibers of extending to a direction and the section shape of group of fibers lamination more than 3 layers or 3 layers that extends to another direction.Particularly, disclose a kind of strenthening member, at the cross section of clathrate body, vertically and laterally placed 4 fiber bundles that fiber constitutes by configuration arranged side by side respectively, lamination obtains this strenthening member for 8 layers.
Summary of the invention
But there is the high problem of manufacturing cost in existing lattice body made of fiber-reinforced synthetic resin.
In addition, in the NOMST job practices, will have lattice body made of fiber-reinforced synthetic resin and reinforcing bar and time spent now, because along with the thickness of lattice body made of fiber-reinforced synthetic resin increases, moment of flexure diminishes, and therefore also has the problem that can't obtain corresponding to the bending strength of fiber total number.
Therefore, the object of the present invention is to provide a kind of low cost of manufacture and in the NOMST job practices with reinforcing bar and the big lattice body made of fiber-reinforced synthetic resin of time spent moment of flexure.
The inventor to achieve these goals, lattice body made of fiber-reinforced synthetic resin is furtherd investigate, found that the prescribed strength that requires according to each member itself that constitutes the clathrate body, under the situation that the fiber total number that uses in each member remains unchanged, if increase the number of plies of cross section fiber bundle, reduce by every layer ribbon number, manufacturing cost is increased, on the contrary, if reduce the number of plies of cross section fiber bundle, increase every layer ribbon number, then make the weakened of cross section sometimes.In addition, the inventor finds that also the reason that existing lattice body made of fiber-reinforced synthetic resin manufacturing cost increases is that the number of plies of cross section fiber bundle is many, and every layer ribbon number is few.And the inventor finds also to determine according to the fiber total number of each member that the number of plies of cross section fiber bundle reduces the intensity of manufacturing cost, raising cross section.
And the inventor finds can reduce the thickness of clathrate body by reducing the number of plies of cross section fiber bundle, and its result is for can be configured in the clathrate body position that can improve bending strength effectively with reinforcing bar and time spent.
The inventor has finished the present invention based on above discovery.
