Detailed description of the invention
Below in conjunction with accompanying drawing and concrete enforcement, structure of the present utility model is described in further detail:
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the utility model provide firstly a kind of linkage for being connected with externally threaded GFRP muscle, and this linkage being used for being connected with externally threaded GFRP muscle comprises connector 6 and adapter sleeve 3; Connector 6 is fixedly connected with by spigot-and-socket with adapter sleeve 3; The cross section of connector 6 is wedge shape; The inwall of adapter sleeve 3 and the profile of connector 6 match.The internal diameter of adapter sleeve 3 is more than or equal to the external diameter of connector 6; When the internal diameter of adapter sleeve 3 is greater than the external diameter of connector 6, the linkage for being connected with externally threaded GFRP muscle also comprises the adhesive layer 4 be filled between adapter sleeve 3 and connector 6; The cementing agent that adhesive layer 4 adopts is fast gravity die cementing agent; The length of connector 6 is not less than 20cm.
Secondly, the utility model additionally provides a kind of externally threaded GFRP muscle of the linkage for being connected with externally threaded GFRP muscle with as above recording, the two ends of connector 6 and adapter sleeve 3, the GFRP muscle body of rod that this externally threaded GFRP muscle comprises the GFRP muscle body of rod and is separately positioned on GFRP muscle body of rod both ends are the GFRP muscle 1 with adapter sleeve and the GFRP muscle 5 with connector respectively.
Wherein, the one end being provided with the GFRP muscle body of rod of adapter sleeve 3 is also provided with transit joint 2; The GFRP muscle body of rod is connected with adapter sleeve 3 by transit joint 2; The external surface of transit joint 2 is circular arc type.
The externally threaded GFRP muscle of the linkage for being connected with externally threaded GFRP muscle with as above recording provided by the utility model can time processing shaping.
Conveniently engineering and transport demand, single GFRP muscle length is advisable with 4 ~ 8 meters, and on-the-spot spreading can adopt many GFRP muscle docking to reach actual needs length; Component for non-integer root muscle body length then can connect corresponding length difference GFRP muscle in termination completes.The docking termination length of GFRP muscle should be greater than 20cm, and concrete size should be determined with GFRP muscle body diameter, and diameter is larger, and the pulling capacity guaranteed needed for docking is larger, then termination length is also longer.Between docking termination and muscle body, interim form is arc surface transition, avoids sectional dimension to suddenly change and causes stress to concentrate.
The inwall of adapter sleeve 3 is designed to guarantee that cementing agent and the GFRP muscle of spreading have and better contacts and have employed wedge inwall, and the inwall ecto-entad of adapter sleeve 3 reduces gradually.Simultaneously in order to ensure spreading GFRP muscle and the preceding paragraph GFRP muscle on the same axis, be designed to cylindrical shape to adapter sleeve outside 5cm, internal diameter is close with the GFRP muscle external diameter docked.
Concrete mode of occupation of the present utility model is: only appropriate cementing agent first need be poured in adapter sleeve, then the GFRP muscular atonia of next section containing connector 6 is rotatably inserted into slowly the top of adapter sleeve 3, and to be bonded dose of condensation docking completes, namely force-applied.
The utility model GFRP muscle replaces reinforcing bar to be applied in the support engineerings such as base pit engineering soldier pile, soil nail wall or tunnel tunnel face, and the points for attention that can refer to straight screw sleeve connection are implemented.Effectively can solve the problem that GFRP muscle is difficult to because of spreading problem promote, spreading mode is simple, easy construction, applicability are strong, environmental protection and energy saving, and cost is lower, has good economic results in society.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to most preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
