Abstract

The utility model belongs to the bridge field, in particular to a bridge connecting part. A composite material bridge span joint, comprises a bridge span body, wherein a bottom plate of the bridge span body is composed of an upper composite material fiber layer and a lower composite material fiber layer; pressure-bearing blocks are arranged on ends of the bridge desk of the bridge span; the bridge span joint also comprises a metal joint inner core and a composite material surface layer covering the metal joint inner core; the metal joint inner core is arranged on the connecting end part of the bottom plate; a connecting hole is arranged; and the composite material surface layer, the upper composite material fiber layer and the lower composite fiber layer of the bottom plate are a seamless and continuous whole body. The composite material bridge span joint solves the connection technology problem of the composite material bridge span, achieves the stress strength requirement of the bridge span and avoids the damage of the bearing performance of the composite material bridge span by mechanical connection.

Description

A kind of composite material spanning joint
Technical field
The utility model relates to a kind of bridge parts, especially a kind of joint of composite material spanning.
Background technology
Height steel or aluminium alloys are as the structural meterials of bridge in traditional can motor-driven bridge is general the employing, and height steel or aluminium alloys were processed during its spanning joint generally also adopted, and were connected the end of bridge through modes such as welding or bolts.Along with the requirement of bridge lightness, the motor-driven bridge of part is brought into use light specific gravity, the better composite material of intensity, like glass fiber and the carbon fiber structural meterials as bridge.Consider metal good ductility and mechanical property, the spanning joint still must be processed by all or part of use metal material, and this joint can't be welded on the end of composite material bridge, can only adopt gluing or mechanical connection.But the glued stressed demand that often can't satisfy bridge then must perforate on compound bridge through mechanical connections such as bolt, rivets, supporting capacity and the application life that must destroy composite material bridge.
Summary of the invention
It is good that the technical problem that the utility model will solve provides a kind of stress performance, do not destroy the spanning joint of composite material bridge supporting capacity.
In order to solve the problems of the technologies described above; This composite material bridge spanning joint comprises the spanning body, and the base plate of spanning body is made up of last composite fiber layer and following composite fiber layer; There is pressure block the bridge deck end of spanning; It is characterized in that this spanning joint also comprises the composite faces of metal joint inner core and coated metal joint inner core, the metal joint inner core is arranged on the connection end of base plate; Be provided with connecting hole, the last composite fiber shop layer of composite faces and base plate is a seamless continuous overall structure with following composite fiber shop layer.
Described composite material bridge spanning joint, its metal joint inner core has a wedge afterbody, the surface of wedge afterbody and last composite fiber shop layer and following composite fiber shop layer bonding.
This spanning joint need not gluing or mechanical connection in the bridge end; Spread the mode of layer coated metal joint inner core through the composite fiber of composite material bridge base plate; Make spanning joint and spanning form an overall structure; Promptly reached the requirement that spanning receives force intensity; Avoided the destruction of mechanical connection to composite material spanning load-carrying properties again, composite fiber was spread the bond area between the layer about the wedge afterbody of its metal joint inner core had increased metal joint inner core and base plate, had increased the stress performance of spanning joint.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the partial enlarged drawing of the utility model metal joint inner core;
Fig. 3 is the connection sketch map of two spannings.
The specific embodiment
As depicted in figs. 1 and 2; This composite material bridge spanning joint; Comprise spanning body 1, the base plate 2 of spanning body 1 is made up of last composite fiber shop layer 3 and following composite fiber shop layer 4, and the bridge deck 8 of spanning body 1 have pressure block 9 by connecting the end; This spanning joint also comprises the composite faces 6 of metal joint inner core 5 and coated metal joint inner core 5; Metal joint inner core 5 is arranged on the connection end of base plate 2, and being provided with 7, two spannings of connecting hole can connect through bearing pin 11 is set in connecting hole.Composite faces 6 is a seamless continuous integral body with the last fiber lay down layer 3 of base plate 2 with following fiber lay down layer 4.During concrete the construction, can earlier metal joint inner core 5 be placed on down above the compound material laying layer 4, descend 4 pairs of metal joint inner core of compound material laying layer to wrap up then, its extension forms compound material laying layer 3.As shown in Figure 3, as required, can cut this spanning joint, cut into ears or three ear shapes, so that two spannings connect.
Learn performance for the pulling force that receives that increases the spanning joint, metal joint inner core 5 can have a wedge afterbody 10, the surface of wedge afterbody 10 and last composite fiber shop layer 3 and following composite fiber shop layer 4 bonding.Because wedge afterbody 10 has increased the surface area of metal joint inner core 5, and also increase greatly of the adhesion stress between the layer of upper and lower composite fiber shop, improve the pulling force that receives of spanning joint and learned performance.
