Specific embodiment
In the following with reference to the drawings and specific embodiments to the supporting knot of cross steel sheet pile described in the utility model and its composition
Structure is described further.
As shown in figures 1-4, cross steel sheet pile described in the utility model include section in criss-cross sheet pile main body 1 and
Heart-shaped pipe when being fixedly arranged on 1 end of sheet pile main body and grafting respectively in transition fit latches 2 and dumb-bell shape lock 3.Sheet pile main body 1
Two pieces of affixed vertical supporting plates 12 of two sides including horizontal peg board 11 and end and 11 middle part of horizontal peg board, one end of horizontal peg board 11 and one piece
The outer end of vertical supporting plate 12 is equipped with heart-shaped pipe lock 2, and the outer end of the other end of horizontal peg board 11 and another piece of vertical supporting plate 12 is equipped with dumbbell
Shape lock 3.
Criss-cross sheet pile main body self structure intensity is higher and more light, can bear the impact of each side's outward force, because
Without introducing H profile steel as reinforcing pile.In addition in the cambered surface that the both ends of pole shape can be latched with heart-shaped pipe in dumb-bell shape lock
Wall fitting, belongs to transition fit, therefore adjacent two cross steel sheet piles are in the permitted deflection angle model of heart-shaped pipe latch openings
All there is preferable sealing performance after enclosing interior connection, the broken line that the horizontal peg board of muti-piece or vertical supporting plate are constituted can be simulated preferably
Segmental arc in supporting construction, thus it is suitble to steel sheet-pile cofferdam of the building containing segmental arc.Criss-cross sheet pile when actual implementation
Main body can be made by hot rolling or fillet welding technique, and heart-shaped pipe lock and dumb-bell shape lock are connect with sheet pile main body with welding manner.
Every above-mentioned cross steel sheet pile all contains there are four lock, is equivalent to four points of connection, at most can be identical as four
Cross steel sheet pile carry out grafting, therefore using the steel sheet pile building steel cofferdam arrangement form it is more versatile and flexible.Horizontal stake
Various forms of locks are provided on the both ends of plate and two pieces of vertical supporting plates, convenient for company of the cross steel sheet pile in transverse direction and longitudinal direction
It connects.
Dumb-bell shape lock 3 includes connecting band 31 and two poles 32 for being fixedly arranged on 31 two sides of connecting band.Connecting band 31 and cross
Peg board 11 or vertical supporting plate 12 are vertical and middle part and the end of horizontal peg board 11 or vertical supporting plate 12 are affixed.
Heart-shaped pipe lock 2 includes that internal diameter is greater than the semi-circular tube 21 of dumb-bell shape 3 width of lock and is set to 21 both ends of semi-circular tube simultaneously
Curved two arc flaps 22 on the inside of to semi-circular tube 21, and the horizontal peg board 11 being greater than in two arc flaps, 22 formation widths
And the opening portion 23 of vertical 12 thickness of supporting plate.The middle part of semi-circular tube 21 and the end of horizontal peg board 11 or vertical supporting plate 12 are affixed.
In the permitted range of deflection angles in opening portion, dumb-bell shape lock can be latched by the pole and heart-shaped pipe at both ends
Middle semi-circular tube or the cambered surface inner wall of arc flap are locally bonded, and belong to cambered surface cooperation, therefore can preferably guarantee that steel sheet pile exists
The water-stagnating effect of junction, and the structure of the two is also all relatively simple.
The internal diameter of arc flap 22 is greater than the diameter of pole 32 and is less than the half of 21 diameter of semi-circular tube, two pieces adjacent in this way
Two poles 32 and arc flap 22 and half when the horizontal peg board 11 or vertical supporting plate 12 of cross steel sheet pile deflect certain angle grafting
Round tube 21 can be preferably bonded, and guarantee the sealing performance of steel sheet pile junction.
The utility model further includes two kinds of supporting construction being made of aforementioned cross steel sheet pile, the first is by linear
Two groups of cross steel sheet piles of arrangement latch 3 by the heart-shaped pipe at horizontal 11 both ends of peg board lock 2 and dumb-bell shape and connect into two rows, and two
Formation is connect with dumb-bell shape lock 3 by 2 button of heart-shaped pipe lock indulged on supporting plate 12 again between row cross steel sheet pile.
Second described in the utility model is by more cross steel by the supporting construction that aforementioned cross steel sheet pile forms
Sheet pile latches the closed polygon supporting construction of 2 and the 3 connection formation of dumb-bell shape lock by the heart-shaped pipe at horizontal 11 both ends of peg board.
Fig. 4 is an application case of the utility model, the supporting construction containing aforementioned two kinds of cross steel sheet piles composition.
The right side of Fig. 4 is a rectangular double-layer steel sheet-pile cofferdam 4 constructed by aforementioned cross steel sheet pile, and each edge in the cofferdam belongs to
The first aforementioned supporting construction, the supporting construction contain two layers of cross steel sheet pile, between two layers of cross steel sheet pile further through
3 connection of heart-shaped pipe lock 2 and dumb-bell shape lock, therefore structure is more firm, and reinforces without H profile steel is introduced.
The left side of Fig. 4 is that a round edge shape single layer steel sheet-pile cofferdam 5 (strictly still falls within single layer polygon cofferdam, only
It is that a plurality of straight flange of polyline shaped can simulate circular cofferdam profile as far as possible, is taken as here circular), belong to aforementioned
Two kinds of supporting construction, since there are certain deflection angles between heart-shaped pipe lock 2 and the cooperation permission steel sheet pile of dumb-bell shape lock 3
It spends and sealing performance is preferable, the broken line that the horizontal peg board 11 of muti-piece is constituted can preferably simulate arc-shaped cofferdam profile again, because
This this steel sheet pile is suitable for cofferdam structure of the building containing segmental arc.The horizontal peg board 11 of every cross steel sheet pile is all answered when inserting piling
Equal angular is deflected to guarantee the final closure in cofferdam towards ipsilateral according to design value with the horizontal peg board 11 of previous steel sheet pile.
It is additionally provided with two rows of steel sheet piles between above-mentioned two steel sheet-pile cofferdam and carries out lateral connection, rectangular double-layer steel sheet-pile cofferdam 4
Left side has two cross steel sheet piles simultaneously with four adjacent steel sheet pile grafting, and four buckle structures thereon all obtain benefit
With, therefore this steel sheet pile is suitble to construct the cofferdam structure of complicated shape.
