Vertically spliced the following is to Wavelike steel webplate built H beam of the present invention, applied mixing this construction of prestressing force
The concrete principle explanation that the feasibility of method, reasonability are made：
Stress of the precast concrete base plate under two states is analyzed first.
1. the 1st state：
Precast concrete base plate as shown in Figure 8, the prestressing force that the stretch-draw prestressing force steel beam set in it is applied is N, then in advance
Section upper stress on concrete floor processed is：
2. the 2nd state：
When above-mentioned precast concrete floor combination turns into I-shaped Wavelike steel webplate combination beam, its I-shape cross section structure is as schemed
Shown in 9.
Apply prestressing force N on precast concrete base plate, the moment of flexure to compound section neutral axis is：
Obtained by the area moment of upper lower section is equal：
The area of combination beam total cross-section is：
The moment of inertia of whole cross section is：
Wavelike steel webplate combination beam can not consider the work of web when anti-bending bearing capacity is calculated due to the non resistance axle power of web
With equivalent to without web plate section, therefore setting：
Then：
The stress of top board：
Make ratio of height to thickness
The then stress of top board：
The stress of base plate：
Have for general combination beam section, can obtain
By taking the Wavelike steel webplate combination beam of 30m across footpaths as an example.If, now, bring formula into（9）With（10）：
When the across footpath of bridge further increases,WithFurther increase, formula（10）Meet
As can be seen here, under the 1st state and the 2nd state, the stress approximately equal of precast concrete base plate.That is, existing in advance
The prestressing force that the prefabricated panel stage applies, is still held essentially constant after Wavelike steel webplate combination beam is overlapped into.Therefore waveform is claimed
Steel web combination beam take it is vertical layered it is assembled before and after this mechanical characteristics that can be held essentially constant of stress for co-bearing not
Denaturation.This characteristic provides the foundation for the vertical layered splicing of Wavelike steel webplate combination beam.
On the basis of above-mentioned analysis, ordinary steel-mixed built H beam and Wavelike steel webplate built H beam is back to discuss
Vertical fractionation with assembly during stress change.Wherein, using prestressing force as only consideration external force：
1. vertical split process：
Figure 10 is the schematic diagram that ordinary steel-mixed built H beam carries out vertical fractionation.
Figure 11 is the schematic diagram that Wavelike steel webplate built H beam carries out vertical fractionation.
2. prestressing force+vertical splicing is mixed：
Schematic diagram when Figure 12 is ordinary steel-mixed built H beam applying mixing prestressing force and vertical splicing.
Figure 13 is schematic diagram when Wavelike steel webplate built H beam applies mixing prestressing force and vertically splices.
Contrast above-mentioned legend to can be seen that for Wavelike steel webplate built H beam, prestressing force is applied just in base plate
It seem an independent process；But the situation of ordinary steel-mixed combination is entirely different.Therefore, can be prefabricated in construction
Apply all or part of prestressing force during concrete floor, then by precast concrete base plate, Wavelike steel webplate and precast concrete
The vertical layered assembly of top board, can so greatly reduce the steel Shu Zhangla workloads at scene, improve factory prefabricating degree.
