Summary of the invention
The technical problems to be solved in the utility model provides a kind of rational in infrastructure for above-mentioned deficiency, linearly can extend laying, can need to do arc whenever and wherever possible according to turning again to lay, be connected tight, gapless, without the need to joint filling, transition is round and smooth, construction is simple and quick, demolition and maintenance convenience and high-efficiency, the alternate fail safe of cable is high, and deposit take up room little, the multipurpose electric power groove of convenient transportation, not cracky.
For solving the problems of the technologies described above, the design feature of this multipurpose electric power groove is: comprise base plate, base plate four limit is comprise parallel minor face and long limit, and the isosceles trapezoid on two isometric waist limits, short leg near minor face on base plate is provided with two minor face holes, on base plate near the long leg on long limit be provided with two long lateral opening, minor face hole and to be longly lateral openingly symmetrical arranged relative to the mid line between minor face and long limit, when two base plates dock with the long limit mode of another base plate according to the minor face of a base plate, corresponding adjacent minor face hole, both sides, docking section and long lateral opening between spacing equal with the spacing in two minor face holes on same base plate, column is fitted with in minor face hole is lateral opening with length, short leg is provided with minor face plate, long leg is provided with long side plate, the leghole that plug-in mounting corresponding to column coordinates is provided with bottom minor face plate and long side plate, base plate is provided with two location notchs be arranged in parallel with minor face, two location notchs are symmetrical arranged relative to the mid line between minor face and long limit, upwards extended dividing plate is fitted with in location notch, minor face plate fastens with long side plate top the cover plate consistent with base plate configuration, cover plate length direction both ends are provided with stomidium, stomidium plug is fitted with in stomidium, linked into an integrated entity by elastic webbing between the abutting end stopple of adjacent cover plate, elastic webbing is installed with colour band.
In the utility model, multipurpose electric power groove is formed primarily of base plate, minor face plate, long side plate, dividing plate, column and cover plate.Wherein, base plate is the core component of this multipurpose electric power groove, and its Main Function, not still for miscellaneous part provides support, be the more important thing is and served guiding or orientation to the laying direction on whole multipurpose electric power line of rabbet joint road.In this multipurpose electric power groove, base plate, to the guiding on whole piece multipurpose electric power line of rabbet joint road or orientation, is not rely on workman's Site Design to complete, but relies on the architectural feature of base plate self to realize.In this multipurpose electric power groove, base plate is isosceles trapezoidal structure, and its four limits are respectively minor face, long limit and two waist limits, wherein minor face shorter than long limit and both be arranged in parallel, the mid point line on two waist edge minor faces and long limit is symmetrical arranged.
For convenience of describing, when being layered in groove by base plate, at the pose pattern on the right side, minor face is called that forward or forward are placed on left long limit, to be called on long limit oppositely or oppositely to place at left minor face at the pose pattern on the right side.When needing the route of multipurpose electric power groove linearly to extend, need the waist limit of two base plates align, and by two adjacent reverse placements of base plate or reverse laying, namely a forward places an oppositely placement, or one is oppositely placed a forward placement, the like.During reverse placement, the adjacent waist limit alignment of two adjacent bottom plates, and the minor face of a base plate docks with the long limit of another base plate, the long limit of a base plate is docked with the minor face of another base plate.For convenience of describing, this kind of disposing way being become straight line and puts or linear state.Its theoretical foundation is, when linear state, that minor face connects long limit on the left of two adjacent bottom plates, then that long limit connects minor face on right side, again because the minor face of each base plate is isometric, long limit is also isometric, and therefore during linear state, the minor face of each base plate and long limit are all in the same way, linearly extend after ensure that each base plate paving.Also can say so, in the isosceles trapezoidal structure of base plate, the angle on long limit and waist limit is acute angle, and the angle on minor face and waist limit is obtuse angle, this acute angle and obtuse angle and be just in time 180 degree.And when linear state, the adjacent waist limit of two base plates is aligned together, and the long limit 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 plates docking and long limit is 180, namely a straight straight line.
When needs turn round, namely when needs turn to, need the adjacent waist limit alignment of adjacent bottom plates, and two adjacent bottom plates are placed in the same way or laid in the same way, namely or two adjacent bottom plates are all that forward is placed, or two adjacent bottom plates are all reverse placements, the like.The meaning of placing in the same way be exactly the adjacent waist limit alignment of adjacent bottom plates, and the long limit of a base plate is docked with the long limit of another base plate, the minor face of a base plate docks with the minor face of another base plate.For convenience of describing, being called by this kind of disposing way turns round puts or turns 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 identical type, namely, when turning left, left side is that minor face connects minor face, and right side is that long limit connects long limit, when turning right, left side is spreading limit, long limit, and right side is that minor face connects minor face, like this, no matter turn left or turn right, two adjacent bottom plates are exactly be symmetrical arranged for line of symmetry with waist limit of aliging; Again because the angle between the waist limit of base plate and long limit is acute angle, the angle between the long limit of that is two adjacent bottom plates is two acute angle sums, and it must be less than 180 degree, therefore the long limit of two base plates is not in the same way, that is to say turn round or turn to.The angle that two base plates turn to or angle of inclination are exactly the difference of two angles to spreading limit and 180 degree, its numerical value also equals the twice of the difference at acute angle between waist limit and long limit and right angle, for convenience of describing, acute angle between waist limit and long limit is called haunch, 180 and the difference of the twice value of this haunch are called two body steering angle or steering angles.When follow-up placement in the same way the 3rd base plate, the angle on the 3rd the long limit of base plate and first long limit of base plate is exactly two body steering angles of twice, and that is, whole piece multipurpose electric power line of rabbet joint road has turned to the angle of two body steering angles of twice; When follow-up placement in the same way the 4th base plate, the angle on the 4th the long limit of base plate and first long limit of base plate is exactly the two body steering angles of three times, that is whole piece multipurpose electric power line of rabbet joint road has turned to the angle of the two body steering angles of three times, by that analogy, till meeting the requirements of steering angle.In actual applications, because the angle between waist limit and long limit is typically provided to the larger acute angle of numerical value, so make the numerical value of two body steering angles less, that is the steering angle of each follow-up base plate is very little, the object that wide-angle (as 90 degree) turns to so just can be reached by the mode of how placing follow-up base plate in the same way, therefore, turning to of this multipurpose electric power groove is very round and smooth, is particularly suitable for the provided underground engineering use of single-core cable, optical cable.
Short leg near minor face on base plate is provided with two minor face holes, and be fitted with the column vertically arranged in minor face hole, the Lower Half of column is inserted in minor face hole, and the first half of column exposes minor face hole.Short leg is also placed with minor face plate, and minor face plate is upwards extended.Be provided with leghole bottom minor face plate, leghole coordinates with two corresponding plug-in mountings in column top of short leg.Like this, minor face plate, by column and the minor face hole coordinated with column upper and lower plug-in mounting, leghole, not only achieves the connection of minor face plate and base plate short leg, and achieves both location, both position relationships is fixed and uniquely.
Same, base plate is provided with on the long leg on long limit two long lateral opening, long lateral opening in be also fitted with the column vertically arranged, the Lower Half of column be inserted to long lateral opening in, the first half of column exposes long lateral opening.Base plate long leg is also placed with long side plate, and long side plate is upwards extended.Be provided with leghole bottom long side plate, leghole coordinates with two corresponding plug-in mountings in column top of long leg.Like this, long side plate is by column and the length that coordinates with column upper and lower plug-in mounting is lateral opening, leghole, not only achieves the connection of long side plate and base plate short leg, and achieves both location, both position relationships is fixed and uniquely.

The other end of minor face plate i.e. concave end Outboard Sections are provided with the inner fovea part of indent, and inner fovea part has two sidewalls, and one is the sidewall extended to minor face intralamellar part from minor face plate concave end end wall, are called interior straight wall for convenience of describing; Another sidewall is the sidewall that side direction minor face intralamellar part extends outside minor face plate, is called inner end wall for convenience of describing.Namely remainder after such minor face plate concave end removing inner fovea part forms the interior protuberance of relative evagination, and also namely interior protuberance is the part surrounded by interior straight wall, concave end end wall and minor face plate madial wall.In the utility model, interior protuberance and the adjacent or total sidewall of inner fovea part are interior straight wall, and interior straight wall and minor face plate sidewall be arranged in parallel.
Same, at long side plate two ends, also namely epitaxial end and concave end are also respectively arranged with epitaxy part, outer recess and interior protuberance, inner fovea part, and between epitaxy part and inner fovea part, between outer recess and interior protuberance, also there is the plug-in mounting relation cooperatively interacted.Its difference is, the epitaxy part on long side plate and inner fovea part are arranged on long side plate end wall inboard portion, and outer recess and interior protuberance are arranged on long side plate end wall Outboard Sections, and its effect is identical, no longer carefully states at this.
No matter be the epitaxy part on minor face plate, outer recess, interior protuberance, inner fovea part, or epitaxy part, outer recess, interior protuberance, inner fovea part on long side plate, when adjacent two base plates according to the alignment of adjacent waist limit and minor face is laid spreading limit, long limit docking minor face mode time, also namely reverse placement or reverse laying time, on base plate, minor face plate and outer recess corresponding to long side plate coordinate with interior protuberance plug-in mounting, epitaxy part coordinates with inner fovea part plug-in mounting.And when adjacent two base plates according to the alignment of adjacent waist limit and minor face docking minor face, long limit are laid spreading limit mode time, also namely place in the same way or when laying in the same way, just there are two kinds of matching relationships.When the outer wall of first minor face plate epitaxy part is assembled on base plate as the outer wall of minor face plate, with it plug-in mounting coordinate second minor face plate interior straight wall by with skew wall snug fit in this epitaxy part, now between the two fit clearance mainly in the fit clearance in face and face between Zhi Bi and interior skew wall, gap is very little, effectively can avoid the inflow of " cable tube " outside earth, silt, ensure the cleaning of " cable tube " inner chamber.When the outer wall of first minor face plate epitaxy part is assembled on base plate as the inwall of minor face plate, angles by two base plates placed in the same way affects, there is an acute angle by the first minor face plate epitaxy part between skew wall in the interior straight wall of second minor face plate of plug-in mounting cooperation with it, and this acute angle is larger than inner bevel, now fit clearance is the line face fit clearance of interior Zhi Bi end and interior skew wall or the line line fit clearance between interior Zhi Bi end and minor face plate end wall between the two, gap is also very little, also " cable tube " outside earth can effectively be avoided, the inflow of silt, ensure the cleaning of " cable tube " inner chamber.The end wall at minor face plate two ends is arranged to round and smooth cambered surface, can effectively avoid like this, intersecting conflict phenomenon when coordinating, ensure that the smoothness of cooperation.As a same reason, between two long side plates, also there is above-mentioned matching relationship, act on similar, no longer carefully state at this.
As improvement, the acute angle of interior skew wall and minor face plate sidewall is the twice of the difference at acute angle between waist limit and minor face and right angle.
Acute angle between the waist limit of base plate and minor face is exactly the haunch described above.When placing in the same way, also namely align in the waist limit of two adjacent bottom plates, and long limit is to spreading limit, and during minor face docking minor face, the angle between the minor face of two base plates is two haunch sums.And a minor face is two haunch sums relative to the angle of inclination of another minor face, or 180 degree of differences deducting two haunch, and this difference just in time equals the twice of the difference at haunch and right angle.Again because minor face plate and minor face be arranged in parallel, therefore can say, a minor face plate is exactly the twice of the difference at haunch and right angle relative to the angle of inclination of another minor face plate.In the utility model, the acute angle of interior skew wall and minor face plate sidewall is the twice of the difference at acute angle between waist limit and minor face and right angle, also the twice of i.e. haunch and the difference at right angle, and therefore interior skew wall and minor face plate sidewall be arranged in parallel.Such setting, clapboard can be made to coordinate with interior protuberance fit together perfectly, just right, the earth that not only can effectively prevent " cable tube " outside, silt flow into, also more simple when assembling, and need not revise, contribute to improving construction quality and efficiency.
As improvement, minor face plate and long side plate top are also provided with the upper pillar stand hole that plug-in mounting corresponding to base plate upper pillar stand coordinates, and before and after minor face plate is inverted, minor face plate corresponding end is equal with waist limit spacing, and before and after long side plate is inverted, long side plate corresponding end is equal with waist limit spacing.
After minor face plate and long side plate top arrange upper pillar stand hole, just minor face plate and long side plate can be inverted or be put upside down, and be inserted on base plate by the column on base plate.Because minor face plate and long side plate both ends are separately not identical, and the left and right sides of each end is also different, therefore, " inversion " function makes putting of minor face plate and long side plate more flexible, no matter just releasing is put upside down, turning of minor face plate and long side plate can being realized join, because of this reducing assembly difficulty, contributing to raising efficiency of construction.No matter compare before putting upside down with after putting upside down, be minor face plate or long side plate, and the distance on its distance base plate waist limit, two ends is all correspondent equal.That is, before putting upside down, the distance on minor face plate epitaxy part distance waist limit with put upside down after the distance on epitaxy part distance waist limit be equal, meanwhile, the distance on interior protuberance distance waist limit put upside down before with put upside down after be also equal.In like manner, long side plate is also like this, does not repeat them here.The object of such setting base plate, minor face plate and long side plate is laid forward and lays backward to accomplish to be symmetrical arranged, just more flexible when constructing like this, lays and all can not make mistakes, contribute to improving efficiency of construction toward which.
As a kind of implementation, described column cross-section peripheral shape is symmetrical arranged in the vertical and is also symmetrical arranged in the horizontal.

In the utility model, multipurpose electric power groove is formed primarily of base plate, minor face plate, long side plate, dividing plate, column and cover plate.Wherein, base plate is the core component of this multipurpose electric power groove, and its Main Function, not still for miscellaneous part provides support, be the more important thing is and served guiding or orientation to the laying direction on whole multipurpose electric power line of rabbet joint road.In this multipurpose electric power groove, base plate, to the guiding on whole piece multipurpose electric power line of rabbet joint road or orientation, is not rely on workman's Site Design to complete, but relies on the architectural feature of base plate self to realize.In this multipurpose electric power groove, base plate is isosceles trapezoidal structure, and its four limits are respectively minor face, long limit and two waist limits, wherein minor face shorter than long limit and both be arranged in parallel, the mid point line on two waist edge minor faces and long limit is symmetrical arranged.
For convenience of describing, when being layered in groove by base plate, at the pose pattern on the right side, minor face is called that forward or forward are placed on left long limit, to be called on long limit oppositely or oppositely to place at left minor face at the pose pattern on the right side.When needing the route of multipurpose electric power groove linearly to extend, need the waist limit of two base plates to align, and by two adjacent reverse placements of base plate, namely a forward is placed one and is oppositely placed, or one is oppositely placed a forward and places, the like.During reverse placement, the adjacent waist limit alignment of two adjacent bottom plates, and the minor face of a base plate docks with the long limit of another base plate, the long limit of a base plate is docked with the minor face of another base plate.For convenience of describing, this kind of disposing way being become straight line and puts or linear state.Its theoretical foundation is, when linear state, that minor face connects long limit on the left of two adjacent bottom plates, then that long limit connects minor face on right side, again because the minor face of each base plate is isometric, long limit is also isometric, and therefore during linear state, the minor face of each base plate and long limit are all in the same way, linearly extend after ensure that each base plate paving.Also can say so, in the isosceles trapezoidal structure of base plate, the angle on long limit and waist limit is acute angle, and the angle on minor face and waist limit is obtuse angle, this acute angle and obtuse angle and be just in time 180 degree.And when linear state, the adjacent waist limit of two base plates is aligned together, and the long limit 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 plates docking and long limit is 180, namely a straight straight line.
When needs turn round, namely when needs turn to, need the adjacent waist limit alignment of adjacent bottom plates, and two adjacent bottom plates are placed in the same way, namely or two adjacent bottom plates are all that forward is placed, or two adjacent bottom plates are all reverse placements, the like.The meaning of placing in the same way be exactly the adjacent waist limit alignment of adjacent bottom plates, and the long limit of a base plate is docked with the long limit of another base plate, the minor face of a base plate docks with the minor face of another base plate.For convenience of describing, being called by this kind of disposing way turns round puts or turns 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 identical type, namely, when turning left, left side is that minor face connects minor face, and right side is that long limit connects long limit, when turning right, left side is spreading limit, long limit, and right side is that minor face connects minor face, like this, no matter turn left or turn right, two adjacent bottom plates are exactly be symmetrical arranged for line of symmetry with waist limit of aliging; Again because the angle between the waist limit of base plate and long limit is acute angle, the angle between the long limit of that is two adjacent bottom plates is two acute angle sums, and it must be less than 180 degree, therefore the long limit of two base plates is not in the same way, that is to say turn round or turn to.The angle that two base plates turn to is exactly two angles to spreading limit, and the numerical value of this angle equals the twice of the difference at acute angle between waist limit and long limit and right angle, for convenience of describing, this angle is called two body steering angles.When follow-up placement in the same way the 3rd base plate, the angle on the 3rd the long limit of base plate and first long limit of base plate is exactly two body steering angles of twice, and that is, whole piece multipurpose electric power line of rabbet joint road has turned to the angle of two body steering angles of twice; When follow-up placement in the same way the 4th base plate, the angle on the 4th the long limit of base plate and first long limit of base plate is exactly the two body steering angles of three times, that is whole piece multipurpose electric power line of rabbet joint road has turned to the angle of the two body steering angles of three times, by that analogy, till meeting the requirements of steering angle.In actual applications, because the angle between waist limit and long limit is typically provided to the larger acute angle of numerical value, so make the numerical value of two body steering angles less, that is the steering angle of each follow-up base plate is very little, the object that wide-angle (as 90 degree) turns to so just can be reached by the mode of how placing follow-up base plate in the same way, therefore, turning to of this multipurpose electric power groove is very round and smooth, is particularly suitable for the provided underground engineering use of single-core cable, optical cable.
Short leg near minor face on base plate is provided with two minor face holes, and be fitted with the column vertically arranged in minor face hole, the Lower Half of column is inserted in minor face hole, and the first half of column exposes minor face hole.Short leg is also placed with minor face plate, and minor face plate is upwards extended.Be provided with leghole bottom minor face plate, leghole coordinates with two corresponding plug-in mountings in column top of short leg.Like this, minor face plate, by column and the minor face hole coordinated with column upper and lower plug-in mounting, leghole, not only achieves the connection of minor face plate and base plate short leg, and achieves both location, both position relationships is fixed and uniquely.
Same, base plate is provided with on the long leg on long limit two long lateral opening, long lateral opening in be also fitted with the column vertically arranged, the Lower Half of column be inserted to long lateral opening in, the first half of column exposes long lateral opening.Base plate long leg is also placed with long side plate, and long side plate is upwards extended.Be provided with leghole bottom long side plate, leghole coordinates with two corresponding plug-in mountings in column top of long leg.Like this, long side plate is by column and the length that coordinates with column upper and lower plug-in mounting is lateral opening, leghole, not only achieves the connection of long side plate and base plate short leg, and achieves both location, both position relationships is fixed and uniquely.
Long side plate and minor face plate are by after in stud location to base; minor face plate, long side plate have become " cable trough " of a cross section in " U " shape with base plate with regard to fast construction; 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 this multipurpose electric power groove, minor face hole and long to be lateral openingly symmetrical arranged relative to the mid line between minor face and long limit, that is, minor face hole and long lateral opening size that to be identical, two minor face holes spacing and two long lateral opening spacing be is isometric, two minor face pitch-rows from spacing and the spacing on two long lateral opening distance limits of minor face be equidistant, minor face hole and length lateral opening be that a left side is right-aligned.
In this multipurpose electric power groove, when two reverse placements of base plate, and during the alignment of the waist limit of two base plates, namely a base plate forward is placed a base plate and is oppositely placed, namely the minor face of a base plate docks the long limit of another base plate, when the minor face of another base plate is docked on the long limit of a base plate.Corresponding adjacent minor face hole, docking section (namely docking the waist limit of coincidence) both sides and long lateral opening between spacing equal with the spacing in two minor face holes on same base plate, that is, two minor face holes of two rear homonymies of base plate docking and two long these four same side openings lateral opening are (for convenience of describing, two minor face holes of homonymies after the docking of two base plates and two are longly lateral openingly called same side opening) line track be positioned at same straight line, and four are equal with two adjacent homonymy pitchs of holes any in side opening.The object of such setting is, no matter minor face plate or long side plate can be inserted on any two adjacent homonymy holes on two base plates after docking by column, that is, minor face plate and long side plate not only can be inserted on independent base plate by column, are also inserted into close on docking section two with on side opening by column.Obviously, when minor face plate or long side plate are inserted on independent base plate by column, this minor face plate or long side plate will be carried separately by this base plate.And when minor face plate or long side plate to be inserted into by column two of closing on docking section with on side opening time, this minor face plate or long side plate are then carried jointly by two base plates of this docking, now, due to the relation that is located by connecting of column, this minor face plate or long side plate also have the effect being fixedly connected with this two docking base plate, each docking base plate is fixed together successively, enhance the cohesiveness on each floor length direction or attachment force, effectively ensure that the structural stability on whole piece multipurpose electric power line of rabbet joint road, be particularly suitable in geology soft, yielding or unstable region and earthquake region use.
