Abstract
The present invention relates to a corrugated plane component made from a punched steel plate. A corrugated shape is composed of upper loading surfaces (3) and grooves (4) in order. A certain interval apart at an upper part, horizontal thickness decreasing regions (14) traversing the whole component and having the smallest thickness are produced by flattening a lower part upward and are the regions where a plane contacts cross beams when the plane is overlapped on a supporting structure (16). The plane component is used on a lorry as the base plate of a packing box.
Description
What the present invention relates to is as the base plate of lorry (compartment) or the flat-bed planar plate members of flat truck.One of application of the present invention is the vehicle (to call automobile car in the following text) of transporting cars, and member can make very big, and can cut into the size of needs according to the size of car chassis.
The structure of present automobile car is such: people are layered on the reinforcement steelframe on chassis with the plain plate of boring, this chassis has the crossbeam that is connected on the longeron, the boring steel plate is layered on above them, consider the mechanical load in the transportation, the support framework of automobile car and covering steel plate must firmly couple together.Therefore, underwork and boring steel plate need at the many places weld together, these requirements mechanically make many weld seams be in and are difficult to approaching place, because vehicle often is exposed in the open, requirement seals the junction with waterproof material, these requirements cause the difficulty of making and raise the cost, in addition, crossbeam generally is to make with the stocking of the closed cross-section of special cross-section or even atresia, makes the mode of promptly using air spraying also be difficult to make the place that anti fouling composition, paint and purging medium reach to be needed.
Owing to lack maintenance and maintenance, make this class formation owing to the erosion of wind and rain destroys in advance with carrying out the actv. protection.In addition, the inside face of the stocking of closed cross-section can't be checked.
Because the wheelbase of vehicle of transportation differs greatly, make the width of the flat board made of the boring steel plate be difficult to adapt with it, the width of Yao Qiuing reaches the twice of steel plate specification sometimes.
In order to overcome these inconvenience, the planar plate members of making according to the present invention can make things convenient for, promptly make very long flat board, and can be by making dull and stereotyped end wise self-locking on the crossbeam that directly is stuck in support frame.Therefore, the characteristics of this planar plate members are:
It is to be supported on two adjacent crossbeams itself;
By means of the detachable self-locking mechanism on the length direction, it can be fixed with a very light joint;
It is economical, and adapts to large-scale industrial production;
Its shape is beneficial to paints and is coated with protective material;
Because structure is open, it is very convenient to make that cross-check sum cleans;
Groove can be used to put the bar of some small bores;
Before being installed on the support frame, we can carry out the processing of any needs to the surface of flat board;
Because not welding, making dull and stereotyped can be different metals with underwork, as steel and aluminium;
Below by an example that is without loss of generality, technical characterstic of the present invention and preceence are described; The accompanying drawing that illustrates is:
Fig. 1 is an axle sectional side view with flat board of the planar plate members that two the present invention describe;
Fig. 2 is the shaft side figure that is positioned at a small plate member of horizontal reduction place;
Fig. 3 is the shaft side figure of the head of the planar plate members before the moulding as required;
Fig. 4 is the section-drawing along the length direction of upper hem;
Fig. 5,6, the 7th, transverse cross-sectional view, the position should be the front portion that compresses-flatten the position, middle part and the rear portion in horizontal reduction district mutually.
The present invention has a Promethean thought: steel plate is converted into the last carrying surface and the groove that can punch, with one gradually bending form contact level with the crossbeam of supporting skeleton until the horizontal reduction district of flattening, and do not influence the carrying surface of punching.Planar plate members 1 of the present invention is converted into the transverse wave shape plate 2 that carrying surface 3 (generally being flat), groove 4 and bottom land 5 (for example flat) alternately occur with steel plate.Then the steel plate after the moulding is beaten a series of holes 6 with the method for punching press or cutting along its length in the centre of last carrying surface 3.The limit 7 in hole 6 can upwards be lifted, and for example when being used for car transporter, can prevent to break away; Perhaps (inwardly) forms smooth carrying surface downwards, for example is used for the base plate of transport truck.This bellows-shaped of being made up of last carrying surface 3, flat bottomed groove 4 has guaranteed to satisfy the rigidity of structure of application target, has formed the basic plane of travelling by the groove 4 separated porose carrying surfaces 3 of going up.As shown in Figure 1, when being used for vehicular transport, planar plate members is become by several planar shaped of travelling substantially arranged side by side, and band travels on a formation left side 9 and right 8.The profile of tooth section that the basic configuration of planar plate members of the present invention is made up of many thin-walleds, thin-wall intersection form strengthens crease.We as can be seen, on to strengthen flanging 10 and 11 are the limits of going up carrying surface 3, strengthen flat 5 the limit that flanging 12 and 13 is grooves 4 down.
A principal feature of the present invention is that planar plate members has equidistant and the not equidistant horizontal reduction district 14 of passing whole width.These laterally reduce, and the district constitutes and the contact surface of the crossbeam 15 of supporting construction 16 (for example, the platform of automobile car as shown in Figure 1).This is contained in platform on the chassis has the longeron 17 and 18 of two parallel ridden in left or right direction bands 8,9 as longitudinal boundary.Laterally the reduction district is meant that a width equates with the width on cooresponding crossbeam top or approaching plane domain 19 and the slope 20 and 21 adjacent with this plane domain left and right sides, and plane 19 and slope 20,21 have laterally covered all grooves and the last carrying surface that is in horizontal reduction district.In order to make figure clear, slope is arranged with the section-drawing that hatching is arranged showed (the diagram effect of muscle).Laterally the reduction district forms the material bending in the zone-flattening.The process of flattening is that the lower surface surface pressure that makes progress is near, but the last carrying surface 3 of punching does not deform.For reaching this purpose, the shape of the left and right sides sidewall 22,23 of groove or groove side (as Fig. 2,5) (warpage or other modes) in some way makes its trend that flexing is arranged reach the purpose of flattening, perhaps use certain external mode to guarantee its flexing, as aerofoil, special instrument, pliers etc.
The process of flattening is gradually groove to be flattened in a definite transverse belt, to guarantee that simultaneously carrying surface should not deform, in this process, by bending and be pressed in below the carrying surface 3, bottom land 5 moves up and still keeps plane and last carrying surface 3 to differ a distance by sidewall 22, the 23 thickness decision of bending steel plate in reduced down in thickness district 14.
Another object of the present invention is to guarantee that the hole is unimpeded always, makes that removing water and foul are more convenient, also can lay stopper tab or other anchor fitting in the hole simultaneously.In order to reach this purpose, the height of groove sidewall 22,23 and the position of bending line must be selected to such an extent that make sidewall after the flattening can not block hole 6 even can not influence its flange 7.For the water that may accumulate at bottom land can be flowed away, we are provided with the similar the sort of opening 24 in the end as we can see from the figure in the darkest place of groove between two laterally reduction is distinguished.
The front end of each planar plate members is a laterally reduction district, it can be ridden on the top crossbeam 25, inclined end portion 26 forms a preceding tongue 27, be foremost an ornamental limit and the leg that lands (as shown in this example, can be a pole 28) because the cross section of front end is circular, can be used as and adjacent platform bonded assembly adapter shaft, or when each flat board is separated by little passageway successively, be used to set up an inclined-plane.Connection can be at the top, slope of leading section, also can be at preceding tongue 27 places, and perhaps any or all the opening 24 that discharges water from length direction connects, and preceding tongue makes very convenient from the aerial pickup vehicle, can not bring very big difficulty because of the loading and unloading vehicle.
As previously mentioned, flat board also can be used for common transport truck, the surface is smooth in this case, so that the thing of mobile in the above parcel, chest and freight container one class, in order to reach this purpose, can be with the space in other material (as wooden, plastics) vertical bar filling slot that adapts with cross sectional shape groove that make, make and last carrying surface 3 concordant.
Below we introduce several methods (being not limited to this several method) that make the sidewall flexing of groove, at first be in the middle of the sidewall that highly satisfies the groove do not block the hole, to determine a bending line 29,30 longitudinally.Side plate curves two planes that are mutually certain angle along this line, makes the cross section of cell wall become broken line shape.According to different needs, the broken line shape in groove cross section is also different, and for example: by two trapezoidal hexagons that are connected to form relatively, best form is the shape with two isosceles trapezoids compositions, equally we can to make sidewall be protruding or recessed cydariform.
The method that also has other various generation effect same and result, for example we can make longitudinal band that mechanical strength is lower of middle formation of sidewall.We also can establish a bearing surface along groove or at the position that will be out of shape equally, this bearing surface can be anything, as support the jaw of the instrument of part, similar pliers or retractor, or a cydariform sidewall that is placed on the bar shaped part in the groove, the bar shaped part can be also can being out of shape between relaxation state and stretching state of rigidity.
The present invention also relates to the manufacturing technique method of planar plate members, basic process is: with steel plate bending continuously longitudinally, produce basic bellows-shaped, bellows-shaped is made up of one by one last carrying surface and groove, simultaneously sidewall is converted into and is convenient to the shape of flexing in the future, press vertical a series of holes of beating at last carrying surface, groove is flattened in a transverse belt by certain interval, flattening is that the bottom land carrying surface that makes progress is pressed, last carrying surface is in fixing position, then flat-panel component length is on demand cut off, owing to considered the trend (for example determining the shape of the sidewall of groove) of the distortion of flattening in advance, the technology of flattening can be simply to pressing down, and we it is contemplated that a kind of instrument, when cutting off planar plate members, extrude transverse belt simultaneously.
Because different variation, it is special that technological process can become, as: as aforementioned: with steel plate bending continuously longitudinally, produce basic last carrying surface and the bellows-shaped formed of groove by one by one, simultaneously sidewall is converted into and is convenient to the shape of bending in the future, press vertical a series of holes of beating at last carrying surface, extending in the punching district of horizontal reduction district and both sides thereof, in the part or along whole groove, with a tool holding or push away two sidewalls of groove, help the cell wall flexing, assist the surface of the instrument of flexing can between relaxation state and stretching state, be out of shape according to instruction, support facility can be a cydariform, for example can be a pipe that is placed in the groove, and the pipe that is out of shape under the effect of the liquid that pressurizes can stick out.
Support that in addition the plane can be the jaw of the instrument of a kind of similar pliers or retractor, it is contemplated that a kind of machine that extrudes laterally reduction district simultaneously and flat board is cut into the length of hope here equally.
From top description, various simple variations can be introduced the present invention.
