Embodiment
As Figure 1-Figure 4, crane span structure attachment structure, including the first connecting plate 1, the second connecting plate 2 and crane span structure 10.Described
It is convex hole 12 that, which there is upside crane span structure end, and downside is the connecting plate of slot 11, after crane span structure docks two-by-two, the He of convex hole 12
Slot 11 coordinates respectively at the arc hook 4 of the first connecting plate 1 and arc hook 5.
The first described connecting plate 1 is provided with two upper interface arrangments and two lower interface arrangments.In embodiment, in order to
The intensity of attachment means is improved, spill muscle face can be suppressed with mould on the first connecting plate, at spill muscle face upper end interval
Negative drawing goes out two arc hooks that Open Side Down 4, and upper arc hook is provided with circular adjustment hole；In the lower end both sides in spill muscle face
The arc hook 5 of each stretched opening upwards.It is interval with the upper end of the second connecting plate 2 and arc hook on described two
The mounting hole being engaged.In actual use in order to which clamping is firm, it is respectively equipped with two of the first connecting plate 1 on arc hook
Neck, the upper end size in the installation convex hole 6 on the upside of crane span structure end on convex hole 12 and the second connecting plate 2 and described neck
Size is consistent, and the arc fold bending structure being engaged with the arc hook 5 of described opening upwards is provided with the lower end of the second connecting plate 2
7。
In order to improve the intensity of the second connecting plate 2, arc fold bending 8 is provided with along its length in the upper end of the second connecting plate 2,
The convex hull-shaped reinforcement 9 perpendicular to the length direction of the second connecting plate 2, the convex hull-shaped are provided with the both sides of the second connecting plate 2
Reinforcement 9 is vertical with the direction of described V-arrangement bending 8, arc fold bending 7, effectively raises the overall strong of the second connecting plate 2
Degree.
As shown in figure 4, the installation process of the present invention is to be alignd two-by-two in crane span structure 10, the first connecting plate 1 is tilted into insertion
On the inside of crane span structure, arc hook passes through from crane span structure hole 11,12, and the neck of 1 arc hook of the first connecting plate 4 is placed in the convex hole 12 of crane span structure 10
Between both wings, the first connecting plate 1 is set to be adjacent to crane span structure medial surface；In the lateral surface of crane span structure 10, by the second connecting plate 2 tilt 15 °-
45 °, specified location is penetrated from the arc hook of the first connecting plate opening upwards, the projecting apertures position pair on convex hole site and crane span structure
Qi Shi, rotate the second connecting plate 2, until the inner plane of the second connecting plate 2 and crane span structure outside be bonded, 4 convex holes of the second connecting plate
Both wings are sticked into the neck of the upper arc hook of the first connecting plate 1, complete to clamp.
The operation principle of the present invention is as follows：
First, the height of the arc fold bending of the lower end of the second connecting plate 2 is more than the first connecting plate 1 and dehisced with crane span structure assembling rear side
Chamber size in formula arc hook, then the lower end circular arc bending of the second connecting plate 2 can smoothly tilt what the first connecting plate 1 of insertion was dehisced upwards
In arc hook, crane span structure can be progressively clamped in the rotary course of the second connecting plate 2, this process utilizes the rigidity of steel itself, opens upwards
The steel construction of the arc hook of mouth has preferably elasticity and tensile strength.It is more convenient for firm grip crane span structure, because under the second connecting plate 2
The center of side circular arc bending is in outside, and the power for giving the second connecting plate 2 to provide a larger despining.
2nd, the ultimate range of the both wings of the upside projecting apertures of the second connecting plate 2 and downside arc hook is less than circle on the first connecting plate
The upper plane of arc hook and the distance of downside open mouth type arc hook inner plane, so the second connecting plate 2, in rotation process, upside is convex
The track rotation of upside arc hook outer surface of the both wings in hole along the first connecting plate 1, because the upper arc hook of the first connecting plate
Rigidity be far longer than downside open mouth type circular arc hook structure elasticity, then pulled in rotation process whole second connecting plate 2 to
Upper movement, the elastic deformation of the first connecting plate open mouth type arc hook increase to maximum.Projecting apertures both wings on the upside of the second connecting plate turn
When moving to the upper arc hook neck of the first connecting plate 1, the rigidity disappearance of the upside arc hook of the first connecting plate, downside open mouth type circle
Arc uncinate gyrus bullet pulls the second connecting plate integrally to move down, and enters the first connecting plate so as to the upside projecting apertures both wings of the second connecting plate
Upside arc hook neck in, and the complete clamping of overall structure is made by despining power.
The scheme that the present invention uses, it is first, second connecting plate, by structure design, is meeting crane span structure bearing capacity basis
On realize that the non-bolt of crane span structure quickly clamps, improve more than 5 times of installation effectiveness.Avoid the use of bolt, reduce project into
This.
First connecting plate：Mould suppress matrix muscle, for increase connecting plate self-strength (matrix muscle also has an effect,
Concave bar face and arc hook are reverse, so can effectively avoid the transition arc of arc hook and base surface, make the first connection
Plate is preferably adjacent to bridge ladder side.), upper and lower each two arc hooks of concave bar face negative drawing arc hook.Arc hook is upper on wherein
Plane sets two symmetrical necks, and arc hook transition position sets technique circular hole, and lower arc hook is open mouth type, and circular hole rises when mounted
Booster action.
Second connecting plate：Upper end is adopted as arc fold bending, for increasing connecting plate longitudinal strength, naturally it is also possible to using it
The muscle of his shape；Projecting apertures coordinates with upper arc hook to be clamped；Convex closure is used to increase connecting plate transverse strength, the circular arc bending of lower end with
Lower arc hook coordinates, clamping crane span structure, and increases for increasing connecting plate longitudinal strength.
Scheme provided by the invention, the construction of each field crane span structure is widely suitable for, does not use connecting bolt.Have following
Some advantage：1. directly saving bolt cost, 2. connecting plates are consistent with crane span structure body anti-corrosion, and increase crane span structure entirety uses the longevity
Life, 3. installations are quick, save human cost.4. improve project installation progress.
Upper and lower arc hook stretches out face and is adjacent to crane span structure on the inside of crane span structure, so as to upper and lower arc hook being vertically connected with through crane span structure
Hole, arc neck is placed on the upside of crane span structure between the both wings of convex hole on the first connecting plate, prevents the first connecting plate double swerve；Enter one
It is adjacent on first connecting plate of step above arc hook above the convex type hole of crane span structure, circular arc lower plane is adjacent to crane span structure under the first connecting plate
Lower slot is following, prevents the first connecting plate from teetertottering；Realize the spacing of crane span structure and crane span structure.
(3) second connecting plates tilt the downside arc hook that the first connecting plate of insertion stretches out crane span structure on the outside of crane span structure, and arrival refers to
When positioning is put and (alignd with crane span structure convex in the second connecting plate convex hole), by the tight connecting plate of inner side first, the second connection is then rotated
Plate, the second connecting plate convex hole both wings is entered on the upside of the first connecting plate in arc hook neck, complete installation.
