The specific embodiment
Be elaborated below in conjunction with the accompanying drawing specific embodiments of the invention.Should be understood that the specific embodiment described herein only is used for explanation and explains the present invention, is not limited to the present invention.
In the present invention, do not doing under the situation of opposite explanation, the noun of locality of use typically refers to the direction shown in the accompanying drawing like " upper and lower "." vertically " refers to the length direction of bridge, and " laterally " refers to the width of bridge, and " outside " mentioned in the manual refers to along the both sides of bridge lateral direction.
Shown in Fig. 1 to 19; The present invention provides a kind of bridge, and this bridge comprises i beam 1, this i beam 1 comprise top flange 11a, bottom flange 11b and be supported on top flange 11a and bottom flange 11b between web 12; Wherein, I beam 1 is a plurality of, and these a plurality of i beams 1 are arranged side by side, and adjacent two i beams 1 connect mutually.
After a plurality of i beams 1 connect mutually; The load that acts on the 11a of top flange is delivered to bottom flange 11b through web 12; Because a plurality of i beams 1 connect mutually; Therefore the contact area of bottom flange 11b and bridge pier end face increases, thereby has improved the stability of integral bridge, and has improved the stress performance and the fatigue resistance of bridge.
In the embodiment of the present invention, two i beams 1 have connected to form bridge of the present invention mutually.Should be understood that, in the present invention, can be to connect mutually more than two i beam 1.When a plurality of i beams 1 are connected mutually; Can be with behind a plurality of i beam 1 hoisted in position; The top flange 11a of adjacent i beam 1 is connected mutually; Also can the bottom flange 11b of adjacent two i beams 1 be connect mutually, also can the web 12 of adjacent two i beams 1 be connected mutually, connect mutually as long as can guarantee adjacent two i beams 1.Can also be simultaneously with the top flange 11a of two adjacent i beams connect mutually, bottom flange 11b connects mutually, and web 12 connects mutually.
Preferably, the top flange 11a of adjacent two i beams 1 connects mutually, and the bottom flange 11b of adjacent two i beams 1 connects mutually.Thereby can guarantee that the i beam 1 more than two can be stressed jointly under the effect of load, and then improve the vertical rigidity and the lateral stiffness of bridge of the present invention.And compressive stress and the tensile stress amplitude of said bridge top flange 11a and bottom flange 11b all reduce to some extent, have improved the corresponding strength safety factor, thereby improve the supporting capacity of bridge of the present invention.
Should be noted that after when connecting mutually that should guarantee does not influence the slit that vehicle passes through between the top flange 11b of adjacent two i beams 1 of bridge with a plurality of i beam 1 hoisted in position.Preferably, can the top flange 11a of adjacent two i beams 1 be connected mutually, be unlikely to excessive with the seam between two i beams that guarantee bridge, influence is open to traffic.
Preferably, can be through the mode of connector, the top flange 11a of adjacent two i beams 1 is connected mutually.For example, connector can be the connecting reinforcement among Fig. 5 and Figure 17, also can be the concrete shown in Fig. 1, Fig. 6-9 and Figure 13, Figure 14 and Figure 16 etc.After through connecting reinforcement the top flange 11a of adjacent two i beams 1 being connected mutually, preferably, can also be in the top flange of two i beams 1 seam crossing of 11a fill slip (like cement, concrete etc.).
Preferably, when the bottom flange of adjacent two i beams 1 11b connects mutually, also can use the mode of connector to connect mutually.When connecting bottom flange 11b, can adopt and be connected the same or analogous connector of top flange 11a.
Preferably, the mode that can also overlap each other or dock through the top flange 11a with adjacent two i beams 1, the bottom flange 11b of adjacent two i beams 1 is overlapped each other or docks connects two adjacent i beams 1.
In first kind of embodiment according to bridge of the present invention, the top flange 11a of adjacent two i beams 1 docks mutually, and the bottom flange 11b of adjacent two i beams 1 docks mutually, and is as shown in fig. 1.When the mode through butt joint connects adjacent two i beams 1 mutually, can between the bottom flange 11b that connector (like reinforcing bar or concrete), adjacent two i beams 1 are set between the 11a of the top flange of adjacent two i beams 1, connector be set.
Can utilize concrete that the top flange of adjacent i beam 1 is connected mutually.Promptly; With the top flange 11a of adjacent two i beams 1 relative to each other, the bottom flange 11b of adjacent two i beams 1 relative to each other after; At concreting between two adjacent top flange 11a and between the adjacent bottom flange 11b adjacent two i beams 1 are connected, as shown in fig. 1.
