[Industrial Application Field 1] The present invention relates to a jointless multi-span deck bridge constructed by continuously connecting simply supported deck slabs, and is ideal for urban viaducts, expressway viaducts, and other road bridges. Regarding the slab bridge. [Prior Art] As a road viaduct, there is a deck slab bridge of pure support type. For such simply supported deck slab bridges, composite deck slabs made by combining steel and concrete are used. A block bridge has been developed and is in use. Figure 3 shows the structure of an example of such a simply supported deck bridge.As a one-span bridge, it is thin, lightweight, strong, easy to construct, and has extremely excellent performance at low cost. . In general, urban viaducts and expressway viaducts are constructed over multiple spans. FIG. 7 shows a deck bridge in which conventional simply supported deck slabs are installed in each span. In such a bridge, a simply supported deck bridge 2 is mounted on each span of the piers 1. The simple support conditions are that, in each span, one end of the simply supported deck bridge 2 is moved ff1J + notice: 3, and the other end is 14 before being fixed. 3 before moving and 14 before fixing to accommodate temperature changes.
An expansion joint 15 is installed 6 between them. In this manner, a single-slope bridge with a simple support floor requires expansion joints 15 at the end of each span in order to cope with temperature changes. Therefore, structural continuity is broken at this expansion joint. Due to this, the next problem becomes i=. (2) There is a step X- on the road, and the impact and vibration caused by this step causes a noise problem. ('l) Problems arise in maintenance management such as maintenance, repair, etc. In order to solve this problem, in JP-A-61-57702, a - girder was added to the space between [p pure steel technique]. There is a method of constructing a concrete deck and continuously constructing a pre-prefabricated deck 1- composite deck slab on that 1-C.
However, the bridge would have to be built twice, which would take a long time, and there would be problems with elasticity. Multi-span continuous girder bridges are used for this purpose. FIG. 8 shows five types of bearing ears for the multi-span continuous girder bridge 20. In the multi-span continuous girder bridge 20, one bearing is
The rest of the bridges are all movable, and the continuous girder bridge 2 is supported by one shoe on each intermediate support. Although the multi-span continuous girder bridge 20 does not require expansion joints,
It is unstable in structural calculations, and a negative bending moment 1- is generated at the fulcrum (above the pier 1), and measures are required to deal with the tensile stress on the upper surface of the deck in order to cope with this negative bending moment 1~. . When ground movement or unevenness occurs in the pier 1 due to an earthquake or other cause, there are problems such as stress that cannot be predicted at the time of design. That is, the multi-span continuous girder bridge 20 requires complicated design calculations and is complicated to construct. In particular, in the case of synthetic girders, synthetic deck bridges, I) C deck bridges, etc., there are problems with creep and drying shrinkage of concrete materials, making it difficult for designers to handle them. On the other hand, the stress problem in such an indefinite multi-span continuous girder bridge is simplified as a continuous bridge. Gelper Bridge is 2. Possessed -
It is a continuous bridge constructed by connecting another girder 22 to the pure support girder 21 with an overhanging C-shaped girder, but this Gelper bridge has 23 spans and is continuous only in the 2nd span, and has 4 diameters. Expansion joints will be required at some point, and there is a risk of the bridge collapsing if the joints are severed during an earthquake. ! tIf Kaisho 46-63516 basically belongs to this type 1[5. E Problems to be Solved by the Invention 1 This Akimei has developed a multi-span deck bridge that solves the problems listed in 1-1. By clarifying the midline of design 3 [p and construction, and aiming for continuity in the multi-span continuous section, expansion joints were not required from the multi-span continuous section, and the problem described in iii was solved. . In other words, in the span h) 7, the deck slab bridge connects the concrete 1-floor 11~ and the paved section with simple support mechanical movement) and over multiple spans. 1 to provide

[In a multi-span bridge, the medium-to-pure support slab bridge constructed in each span is connected with slides on each pier. , one of the piers is a fixed bearing, and the curved piers are movable bearings. In addition to a pin connection as a sliding joint, it is also possible to use a structure with rubber interposed (in this case, the girder height can be lowered. Also, if a structure with rubber interposed as a movable support is used, it is possible to use a structure with rubber interposed as a movable support. It is preferable that the entire horizontal force during an earthquake can be dispersed to each pier compared to the above. [Action 1] The multi-span deck bridge of the present invention has Because it is a simply supported deck slab bridge, it does not generate negative moments, and it is mechanically static and has no uncertainties, and does not require complicated drawing calculations, making the design more reliable. , the reliability is extremely high. (2) Therefore, there is no need for complicated structures or countermeasures to deal with complex stresses, and it is inexpensive. (3) Even if subsidence or fluctuation of the piers occurs, , can follow this, and does not generate complicated stress. (4) Even if a pin breaks during an earthquake, there is no risk of the bridge collapsing. (5) Since no expansion joints are required, the life of the floor slab is longer.
The vehicle has good running performance and extremely comfortable ride. ((1) It is recommended that the sliding joint be constructed with an alternating structure between the two sides of the pure supporting slab bridge, and a pin support should be provided at this alternating portion. By replacing this with a structure in which rubber is interposed, pins, rollers, etc. Rubber bearings can be used, which are cheaper than conventional bearings.
Required height of the bearing part in case of pin bearing: 300 to 600
mm can be as low as about 30-60 mm. With pin bearings, the height of the bearing part is high, and in bridges with a low overall structural height, such as synthetic deck bridges and PC deck bridges, it may be difficult to ensure the height of the pin bearing, but with rubber bearings. This will be significantly changed. (7) In movable bearings with rubber interposed instead of roller bearings, the rubber bearings act as semi-fixed during an earthquake, and the force of the entire tree is distributed to each pier. Multi-span floor l1fli using roller bearings! In bridges, the entire tree that grows due to earthquakes ^) - Since the sword is carried only by the fixed metal piers, the fixed metal piers have a large cross section, and the structure of the fixed metal becomes large, or rubber bearings are not used. The best thing to do is to avoid this. [Example] Example 1 Fig. 1 is a cross-sectional side view showing a structural example of a simply supported deck bridge 2 (a pier of a multi-diameter deck bridge according to an embodiment of the present invention in which 2a and 2bJ are combined). A deck slab bridge 2a consisting of a composite slab bridge or an I) C deck slab bridge is supported on a roller support 3 on reinforced concrete or steel piers 1''. The deck slab bridge 2a and the adjacent deck slab bridge 2b have a different structure, and the deck bridges 2a and 2b are connected by providing a bottle support 4 in the different part. The upper surface of the gap between the deck bridges 2a and 2b is covered with a gap material 5 such as foamed cotton roll. A concrete slab 6 and an asphalt pavement 7 are applied to the upper surfaces of the slab bridges 2a and 2b. Since the deck bridges 2a and 2b are connected via the pin support 4, there is no need to provide an expansion joint between the deck bridges 2a and 2b. Additionally, this bridge does not generate negative bending moments at the piers unlike rigid multi-span continuous girder bridges. FIG. 4 shows a jointless multi-span deck bridge constructed with simple supports according to the present invention. The entire fixed bearing 14 is fixed on one pier la. In the multi-span deck bridge of the present invention, in each span, one end is a movable front 3, the other end is a fixed metal (the bin support 4 is free to rotate, and is similar to a fixed metal that restrains movement in the horizontal direction). ) satisfies the conditions. That is, although it is a simply supported deck slab bridge, it is a continuous bridge and does not require expansion joints, and the deck has a structure similar to that of a multi-span continuous girder bridge. Example 2 The support structure of the example using the rubber bearing shown in FIG. 2 was made smaller. In the structural model of the joint stress multi-span deck bridge using pin bearings and roller bearings shown in FIG. 1, the horizontal reaction force generated by an earthquake is borne only by the fixed bearings 14 on the piers la shown in FIG. 4. In other words, the horizontal seismic intensity Kh is multiplied by the upper dead load between the abutments at both ends (W 1+W2 +W3+...-)X
Since Kh=Ht acts as an earthquake load in the bridge axis direction on the fixed support pier 1a and the fixed support 14 installed in the center, the structure of the fixed support 14 becomes large and the cross section of the fixed support pier 1a also becomes large. A form is required. As shown in FIG. 5, when the rubber bearings 8 are used, the same operation is achieved as when elastic springs 16 are interposed between each simply supported deck bridge 2 and each pier (2). 1-The rope can also disperse the earthquake horizontal load Hi acting on each pier l to the abutment north at both ends and to each pier. The relationship between the horizontal load during an earthquake and the shear resistance of the rubber bearing is as follows. FIG. 6 shows how the elastic rubber support 30 is subjected to shearing force. It is assumed that the dead load reaction force W] acting on each span is multiplied by the water seismic intensity K h (W i Assuming that the shear resistance force F acts as a reaction force, (1, l~ Gono\bearing pressure area (crn”) of the bearing body)△
water) 1-dimensional displacement (cm) G, shear modulus of elasticity (kg / cm'') ΣTe: total thickness (cm) of elastic rubber of the support) 'fchi, ■1
From the formula, we can install a rubber support that satisfies the horizontal displacement △ by combining the total thickness of the elastic rubber, bearing pressure area, and shear coefficient of 11J for the horizontal load Hi that occurs in each span during an earthquake. It's good to keep it that way. [Effects of the Invention] Since the joint tress multi-span deck bridge constructed with simple support of the present invention has the above configuration, (1) by adopting a structural form that satisfies the simple support condition in each horn span, , design calculations are easy, construction on site is simple, and even if there is ground movement, stress that is not anticipated at the time of design is unlikely to occur, and reliability is extremely high. (2) In multi-span deck bridges, by eliminating the stretchable knitted hair, the running performance of vehicles is improved. ■ Can prevent impact between expansion joints and tires. ■ Prevent water leakage from expansion joints and prevent corrosion of steel plates. (3) The support on the pier is a single roller bearing, which is installed in the center of the pier, so the structure is difficult to prevent the bridge from collapsing in the event of an earthquake, and the earthquake resistance is improved. By using rubber bearings in place of pin bearings and roller bearings in bridge bridges, it is possible to achieve greater economic efficiency, significantly lowering the height of the bin bearings and keeping the overall height of the deck slabs on the pier bearings low. (5) The movable shoes of the rubber bearing become semi-fixed during an earthquake, and the entire horizontal force is distributed to each pier, making the structure of the fixed bearing more compact.Also, the width of the pier in the axial direction of the bridge can be reduced. be able to.
