In the present invention, the electric power protection groove of knob rapid construction is mainly made up of base plate, minor face plate, long side plate, dividing plate, column and cover plate.Wherein, base plate is the core component of the electric power protection groove of this knob rapid construction; its Main Function does not still provide for miscellaneous part and supports it is often more important that serving guiding or orientation to the laying direction on the electric power protection line of rabbet joint road of whole knob rapid construction.In the electric power protection groove of this knob rapid construction, the guiding on the electric power protection line of rabbet joint road to the rapid construction of whole piece knob for the base plate or orientation, are not to rely on workman's Site Design to complete, but rely on the architectural feature of base plate itself to realize.In the electric power protection groove of this knob rapid construction, base plate is isosceles trapezoidal structure, its four while be respectively minor face, long while and two waist edge, wherein minor face is shorter than long side and both be arranged in parallel, and two waist edge are symmetrical arranged along the midpoint line on minor face and long side.

For convenience of describing, when base plate is layered in groove, minor face is referred to as forward direction on left long side in right pose pattern or forward direction is placed, and long side is referred to as reverse or oppositely positioned in right pose pattern in left minor face.When needing the route of the electric power protection groove of knob rapid construction along straight-line extension; need the waist edge alignment of two base plates, and two adjacent base plates are inversely placed, that is, a forward direction placement one is oppositely positioned; or an oppositely positioned one positive placement, the like.During reverse placement, the adjacent waist edge of two adjacent bottom plates is alignd, and the minor face of a base plate is docked with the long side of another base plate, and the long side of a base plate is docked with the minor face of another base plate.For convenience of describing, this kind of disposing way is become straight line and puts or linear state.Its theoretical foundation is, in linear state, it is that minor face connects long side on the left of two adjacent bottom plates, it is then that long side connects minor face on right side, again because the minor face of each base plate is isometric, long side is also isometric, therefore linear state when the minor face of each base plate and long side be all in the same direction it is ensured that each base plate paving tailing edge straight-line extension.It is also possible that saying, in the isosceles trapezoidal structure of base plate, the angle of long side and waist edge is acute angle, and the angle of minor face and waist edge is obtuse angle, this acute angle and obtuse angle and exactly 180 degree.And in linear state, the adjacent waist edge of two base plates is aligned together, and the long side of two base plates and minor face are docking together, that is an obtuse angle of two base plates and an acute angle are docking together, obviously both sums are also 180 degree, that is the angle between the minor face of two base plate docking and long side is 180, that is, a straight straight line.

When needing to turn round, that is, when needing to turn to, need the adjacent waist edge alignment of adjacent bottom plates, and two adjacent bottom plates placed in the same direction, or that is, two adjacent bottom plates be all positive place, or two adjacent bottom plates are all oppositely positioned, the like.The meaning placed in the same direction it is simply that the adjacent waist edge alignment of adjacent bottom plates, and a base plate long dock in long with another base plate, the minor face of a base plate is docked with the minor face of another base plate.For convenience of describing, this kind of disposing way is referred to as turned round and puts or turn round state.Its theoretical foundation is, when turning round state, the either side of two adjacent bottom plates is all the base plate side of same type, i.e., when turning left, left side connects minor face for minor face, and right side is long when connecting long, when turning right, for long in spreading, right side connects minor face for minor face, so in left side, no matter turning left or turning right, two adjacent bottom plates are exactly to be symmetrical arranged with waist edge of aliging for line of symmetry；Again because the waist edge of base plate and long while between angle be acute angle that is to say, that two adjacent bottom plates long while between angle be two acute angle sums,, certainly less than 180 degree, the long side of therefore two base plates is not in the same direction, that is to say turning round or steering for it.The angle of two base plate steerings is exactly two angles to spreading side, and the numerical value of this angle is equal to the twice of the acute angle between waist edge and long side and the difference at right angle, for convenience of describing, by this angle referred to as two body steering angles.When follow-up place the 3rd base plate in the same direction when, long angle while long with first base plate of the 3rd base plate is exactly two body steering angles of twice that is to say, that the electric power protection line of rabbet joint road of whole piece knob rapid construction has shifted towards the angle of two body steering angles of twice；When the 4th base plate of follow-up placement in the same direction; long angle while long with first base plate of 4th base plate is exactly two body steering angles of three times; that is the electric power protection line of rabbet joint road of whole piece knob rapid construction has shifted towards the angle of two body steering angles of three times; by that analogy, until it reaches till the steering angle of requirement.In actual applications; because the angle between waist edge and long side is typically provided to the larger acute angle of numerical value; so make two body steering angles numerical value less; that is the steering angle of each follow-up base plate is very little; thus can reach, by way of how placing follow-up base plate in the same direction, the purpose that wide-angle (as 90 degree) turns to; therefore, the steering of the electric power protection groove of this knob rapid construction is very round and smooth, is particularly suitable for single-core cable, the provided underground engineering of optical cable uses.

On base plate, the short leg near minor face is provided with two minor face holes, and minor face in the hole is fitted with the column being vertically arranged, and the lower half of column is inserted to minor face in the hole, and the first half of column exposes minor face hole.Minor face plate is also placed with short leg, minor face plate upwardly extends setting.Minor face plate bottom is provided with leghole, and leghole is coordinated with the corresponding plug-in mounting in two column tops of short leg.So, minor face plate pass through column and with column the minor face hole of upper and lower plug-in mounting cooperation, leghole, not only achieve minor face plate and the connection of base plate short leg, and achieve both positioning, so that both position relationships is fixed and uniquely.

Likewise, be provided with the long leg on long side on base plate two long lateral opening, length lateral opening interior be also fitted with the column being vertically arranged, the lower half of column is inserted to that length is lateral opening interior, and it is lateral opening that the first half of column exposes length.Long side plate is also placed with base plate long leg, long side plate upwardly extends setting.Long side plate bottom is provided with leghole, and leghole is coordinated with the corresponding plug-in mounting in two column tops of long leg.So, long side plate pass through column and with column the cooperation of upper and lower plug-in mounting length is lateral opening, leghole, not only achieve long side plate and the connection of base plate short leg, and achieve both positioning, so that both position relationships is fixed and uniquely.

Long side plate and minor face plate pass through stud location on base after; minor face plate, long side plate have become, with regard to fast construction, " cable trough " that a cross section is in " u " shape with base plate; and described single-core cable, optical cable etc. are namely laid in this " cable trough ", serve the protective effect to single-core cable, optical cable.

In the electric power protection groove of this knob rapid construction; minor face hole and length lateral opening are symmetrical arranged with respect to the intermediate line between minor face and long side; that is, the minor face hole and long lateral opening size spacing lateral opening with two length that are identical, the spacing in two minor face holes be isometric, two minor face pitch-rows from the spacing of minor face and the spacing on two long lateral opening distance sides be equidistant, minor face hole and long lateral opening be that a left side is right-aligned.

In the electric power protection groove of this knob rapid construction; when two base plates are inversely placed; and during the waist edge alignment of two base plates; namely base plate one base plate of positive placement is oppositely positioned; namely the minor face of a base plate docks the long side of another base plate, when the minor face of another base plate is docked on the long side of a base plate.Docking section (namely docking the waist edge of coincidence) the both sides adjacent minor face hole of correspondence and length lateral opening between spacing equal with the spacing in two minor face holes on same base plate, that is, after two base plate docking, two minor face holes of homonymy and two long lateral opening this four same side openings are (for convenience of narration, by long to two minor face holes of homonymy after the docking of two base plates and two lateral opening referred to as same side openings) line track be located at same straight line, and four are equal with the adjacent homonymy pitch of holes of any two in side opening.So setting purpose be, no matter minor face plate or long side plate can be transferred through on any two adjacent homonymy holes on two base plates after column is inserted into docking, that is, minor face plate and long side plate not only can be inserted on single base plate by column, also can be inserted into two that close on docking section by column with side opening.Obviously, when minor face plate or long side plate are inserted on single base plate by column, this minor face plate or long side plate individually will be carried by this base plate.And when minor face plate or long side plate be inserted into by column two that close on docking section with side opening on when, this minor face plate or long side plate are then carried jointly by two base plates of this docking, now, the relation that is located by connecting due to column, this minor face plate or long side plate also have the effect being fixedly connected this two docking base plate, make each dock base plate to be fixed together successively, enhance the cohesiveness on each floor length direction or attachment force, the structural stability on the electric power protection line of rabbet joint road of whole piece knob rapid construction has been effectively ensured, it is particularly suitable for soft in geology, yielding or unstable region and earthquake region use.
