Abstract
The utility model relates to a steel corrugated plate. The utility model is characterized in that the thickness of a steel plate is between 2.5 mm and 12 mm; the plane surface of the steel plate forms a corrugated shape; the corrugated steel forms a circular arc shape or a flat plate shape vertically to a wave-shaped axial line, and the periphery is provided with connecting holes; the connecting holes of two adjacent plates are connected through convex arc-shaped bolts, concavearc-shaped pads, or common bolts, concave arc-shaped pads, and convex arc-shaped pads, and nuts; accordingly, a corrugated steel pipeline is formed in the mode of split joint, and the cross section can form a circular shape, an arch shape and an elliptic shape. The utility model is used for the projects of a crossing passage, a tunnel, a strategic bunker, a culvert, a drainage pipeline, etc. of a highway, and has the advantages of high construction speed, low investment, normalized and standardized product, etc.
Description
The utility model is the steel corrugated sheet of highway interconnection, blindage, culvert, drainage pipe, belongs to the building unit class.
As everyone knows, present highway interconnection, tunnel, blindage, culvert, drainage pipe mostly adopt steel concrete or prestressed reinforced concrete construction, the construction of these structures, cast-in-place and the precast assembly method of general employing, but it has defectives such as long construction period, construction costs height, therefore, the inventor once designed a kind of steel corrugated sheet, be combined into steel conduit with it, have good compressive strength and corrosion resistant performance, the patent No. is 96222034.5.Facts have proved, it can make the standardization of product-quality indicators, standardization, speed of application is fast, advantages such as construction investment is economized, and structure is light and handy attractive in appearance, find simultaneously: the steel corrugated sheet is striden the interconnection of footpath in 10 meters, culvert, blindage, drainage pipe etc. except being applied to highway, railway, the duct of different spans can utilize the steel corrugated sheet of different-thickness, and can be spliced into difformity as circle, arch, ellipse, straight shape etc., in order to increase bonding strength, need a kind of special interface unit.
The purpose of this utility model is to disclose a kind of steel corrugated sheet, and a kind of special union piece, with this steel corrugated sheet of different size kind is spliced into interconnection, culvert and the drainage pipe etc. of different shape, can increases bonding strength, increase the service life.
In order to achieve the above object, the utility model is achieved like this.Known from institute, the domes of building unit are than much higher times of straight structure part intensity, therefore, can in 2.5～12mm, select for different purposes steel plate thickness, steel plate plane corrugated in wave shape, corrugated steel are that the width of plate is circular-arc or tabular at the vertical moire axis direction, are spliced into steel conduit with it, it is sinusoidal wave that the passage that can form various cross sectional shapes such as circle, arch, ellipse and straight shape, the waveform of corrugated steel are.For the ease of splicing, the periphery of corrugated steel has connecting hole, and in order to increase bonding strength, connector has identical curvature with corrugated steel, and there is anticorrosive coat on the surface of plate and connector, to increase application life.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is a steel corrugated sheet profile schematic diagram,
Accompanying drawing 2 is a steel corrugated sheet syndeton schematic diagram,
Accompanying drawing 3 is the convex bolt,
Accompanying drawing 4 is the steel corrugated sheet syndeton schematic diagram of employing convex-concave arc pad plain bolt,
Accompanying drawing 5 is the convex pad,
Accompanying drawing 6 is the arcs of recesses pad,
(1) with reference to the accompanying drawings, the steel corrugated sheet is to be that the punching of the steel plate of 2.5～12mm becomes the ripple corrugated by thickness, corrugated steel (being the width of plate) on the vertical moire axis direction is circular-arc, the radius of curvature of circular arc can design according to engine request, corrugated steel also can be tabular, the same thickness corrugated sheet, can be spliced into the corrugation steel conduit, can form circle, arch, the steel plate member of different cross section shapes such as oval or straight shape, have connecting hole on the periphery of every corrugated steel, the surface of plate scribbles anticorrosive coat, be connected with nut by connecting bolt between plate and the plate, with reference to the accompanying drawings 2, steel corrugated sheet (1), (2) by convex bolt (3) and arcs of recesses pad (4), then by fastening the forming of nut (5), the radian radius of curvature of convex arc bolt (3) and spill pad (4) is identical with the radius of curvature of steel plate (1) (2), to increase bonding strength, can be as accompanying drawing 4, adopt plain bolt (6) and convex pad (7) and arcs of recesses pad (4), by fastening the forming of nut (5), it is sinusoidal wave that the waveform of corrugated steel is then.
Adopt steel corrugated sheet and connector thereof to replace traditional reinforced concrete technology, can realize factory normalization production, on-site consolidation has advantages such as the standardization of product-quality indicators, standardization, speed of application are fast, construction investment province.
Claims (3)
1. steel corrugated sheet that is applicable to highway interconnection, drainage pipe, war preparedness blindage, tunnel, culvert, it is characterized in that steel plate thickness is between 2.5～12mm, the steel plate plane is the ripple corrugated, corrugated steel is circular-arc or tabular on the vertical waveform axis, periphery has connecting hole, the connecting hole of adjacent two plates is with bolt (3) or (6), pad (4) or (4) and (7), nut (5) fastening connection piece, connects to form that the cross section is rounded, arch, ellipse or straight shape member.
2. steel corrugated sheet according to claim 1, it is characterized in that when selecting for use the convex bolt to connect, then form a harness fastener, also can select for use plain bolt (6), convex pad (7), arcs of recesses pad (4) and nut (5) to form a harness fastener by convex bolt (3), arcs of recesses pad (4), nut (5).
3. steel corrugated sheet according to claim 1 and 2 is characterized in that the arc bolt, and arc pad and steel corrugated sheet have identical radius of curvature.
