Abstract
The utility model relates to a kind of bridge expanssion joint protection of welded joints structures.The protection of welded joints (1) is in rectangular parallelepiped structure form, with the axial notch (2) that placement cable is arranged, protection of welded joints (1) outer bottom forms following structure type: including the spaced several link blocks (3) being connected on outer bottom, pulley (4) are provided between adjacent link block (3).The utility model by placing safeguard structure in expansion joint, avoid cable in dragging process directly with ground face contact and caused by abrasion, improve the service life of cable；Further pulley is arranged in safeguard structure bottom in the utility model simultaneously, so that pulley and ground form the friction type rolled, also reduce abrasion of the safeguard structure in use between ground, the service life for improving the safeguard structure ensure that the long-term firm operating of whole device.
Description
Technical field
The utility model relates to a kind of bridge expanssion joint protection of welded joints structure, the structure mainly for prevent herein cable exist
The abrasion generated in use process.
Background technique
It refers to meet the requirement of bridge floor deformation, usually between two beam-ends, between beam-ends and abutment or the hinge of bridge
It connects and expansion joint is set on position.It is required that expansion joint it is parallel, perpendicular to the both direction of bridge axes, can free extension, jail
Gu reliable, vehicle driving is out-of-date to be answered smoothly, without kick and noise；It wants to prevent rainwater and rubbish soil from penetrating into obstruction；Installation, inspection
Look into, conserve, eliminate dirt will simple and convenient.
In expansion joint joint, relevant apparatus is generally set, such as cable, existing structure type is often directly electricity
Cable is directly placed within the empty slot of expansion joint connector formation, so that cable directly and notch ground face contact, is using dragging cable
It is easy that cable is made to generate abrasion in the process, influences the safe operation of bridge, need further to be improved.
Utility model content
The utility model can carry out the devices such as cable good in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structurally reasonable
The bridge expanssion joint protection of welded joints structure protected well.
The technical solution adopted in the utility model is thus: bridge expanssion joint protection of welded joints structure, the protection of welded joints (1)
In rectangular parallelepiped structure form, there is axial setting to place the notch (2) of cable, protection of welded joints (1) outer bottom forms following
Structure type: including the spaced several link blocks (3) being connected on outer bottom, it is arranged between adjacent link block (3)
There are pulley (4).
The protection of welded joints (1) includes groove body (7) and the slot cover (5) being connected on groove body (7), the groove body (7) and
Slot cover (5) formation is detachably connected form and forms the notch (2).
Groove body (7) upper side is epitaxially formed boss (11), and slot cover (5) lower surface is supported and is located at the boss
(11) on；
Fracture is formed on the boss (11), the fracture is penetrated for the reinforcement block (12) being installed on groove body (7),
Slot cover (5) corresponding position, which is provided with, reinforces convex block (51), the reinforcement block (12) and reinforces that convex block (51) are interior to be provided with pair
The internal screw thread answered, is provided with that fastener (6) is corresponding with the internal screw thread, forms the connection of groove body (7) and slot cover (5).
The reinforcement block (12) extends to the bottom surface of the groove body (7), and in the middle part of the groove body (7) bottom surface, institute
It states link block (3) and pulley (4) is symmetricly set on the groove body (7) bottom surface both side.
The utility model has the advantages that: the utility model avoids cable by placing safeguard structure in expansion joint
In dragging process directly with ground face contact and caused by wear, improve the service life of cable；Simultaneously the utility model into
Pulley is arranged in safeguard structure bottom in one step, so that pulley and ground form the friction type rolled, also reduces protection knot
The structure abrasion between ground in use, improves the service life of the safeguard structure, ensure that whole device
Long-term firm operating.

Specific embodiment
Bridge expanssion joint protection of welded joints structure, the protection of welded joints 1 are in rectangular parallelepiped structure form, and there is axial setting to place
The notch 2 of cable, 1 outer bottom of protection of welded joints form following structure type: including the interval setting being connected on outer bottom
Several link blocks 3, be provided with pulley 4 between adjacent link block 3.
The protection of welded joints 1 includes groove body 7 and the slot cover 5 being connected on groove body 7, and the groove body 7 and the formation of slot cover 5 can
Dismantling connection form simultaneously forms the notch 2.
7 upper side of groove body is epitaxially formed boss 11, and 5 lower surface of slot cover is supported and is located on the boss 11；
Fracture is formed on the boss 11, the fracture is penetrated for the reinforcement block 12 being installed on groove body 7, in the slot
5 corresponding position of lid, which is provided with, reinforces convex block 51, is provided with corresponding internal screw thread in the reinforcement block 12 and reinforcement convex block 51, is arranged
There are fastener 6 and the internal screw thread corresponding, forms the connection of groove body 7 and slot cover 5.
The reinforcement block 12 extends to the bottom surface of the groove body 7, and in the middle part of 7 bottom surface of groove body, the connection
Block 3 and pulley 4 are symmetricly set on 7 bottom surface both side of groove body.
Indent and convex structure type is arranged in bottom face in the protection of welded joints of the utility model, and the purpose is to be placed on it
Interior cable provides certain restraining force, reduces the relative displacement of cable in use；The further slot of the utility model
The connection structure form of lid 5 and groove body 7 while guaranteeing the two connection reliability, while being also played to 7 intensity of groove body
