Description
Technical field
The utility model relates to temporarily driving is belonged in bridge construction process by device at a kind of bridge expanssion joint notch
Expansion joint notch protective device technical field.
Background technique
With the continuous development of society, bridge construction is also rapidly developed.During bridge construction, temperature
Variation easily cause expanding with heat and contract with cold for pavement structure, will cause when pavement structure expands with heat and contract with cold excessive deformation, destroy, seriously affect
The service life of bridge increases maintenance, construction cost, therefore, usually between two beam-ends, between beam-ends and abutment or bridge
Expansion joint is set in articulated position, is used for pavement structure displacement buffering.
After erection of precast beams before the construction of expansion joint, the large-scale construction equipments such as beam car and other works in bridge construction process
Journey vehicle must cause at notch embedded bar to bend even severely deformed deviation, later period expansion joint by notch position
It needs to readjust reinforcing bar when installation, wastes a large amount of manpower and time, increase construction cost, and influence later period expansion joint
Installation quality.It directly drives a vehicle currently, several lumps of wood or sand is mostly used to fill at expansion joint or even do not process, by
It is unstable in sand or the lumps of wood, it is easily deformed and moves, implementation result is undesirable, and is easy to cause construction site chaotic, civilization
Construction level is low, and the later period is needed to be handled, and handles time-consuming.
Summary of the invention
The technical problem to be solved by the present invention is to provide temporarily drivings at a kind of this bridge expanssion joint notch to pass through dress
It sets, it can be with overcome the deficiencies in the prior art.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions: a kind of bridge expanssion joint
Temporarily driving is by device at notch, it is arranged on the expansion joint notch of bridge, including shape steel support, supporting steel plate and arc
Shape cover board offers elongated groove on the curved cover plate lower surface, and the contour structures of the supporting steel plate and elongated groove are equal
Match with shape steel support, the supporting steel plate is connected on shape steel support upper surface, and the two is placed in curved cover plate
In elongated groove.
Aforementioned curved cover plate is arc rubber structure, and upper surface is middle section radian, two sides are symmetrically arranged straight
Line gradient structure；Lower surface is planar structure.
The I-steel girder and junction steel plate that aforementioned shape steel support is arranged by two pieces form, and the both ends of the two are connected one by one
Get up, constitutes rectangular frame structure, the upper surface of the I-steel girder is middle section plane, two sides are symmetrically arranged
Bevel structure；Lower surface is planar structure.
It is equipped with ribs in the side of aforementioned I-steel girder, the flat of I-steel girder upper surface is arranged in the ribs
Below face, inclined-plane intersection point.
Compared with the prior art, the utility model discloses temporarily driving at a kind of bridge expanssion joint notch and passes through device, packet
Shape steel support, supporting steel plate and curved cover plate are included, elongated groove, the supporting steel are offered on the curved cover plate lower surface
Plate is connected on shape steel support upper surface, and the two is placed in the elongated groove of curved cover plate, the shape steel support two sides
I-steel girder including two variable cross-sections, the installation of I-steel girder both ends are fixed by junction steel plate, the supporting steel plate installation
In type steel support top of the trellis, the two forms main body stress frame, and main body stress frame is nested in curved cover plate, so that this
Device intensity is high, can carry various large-sized trucks and pass through, long service life；The curved cover plate is arc rubber structure, price
Low, light-weight, convenient in carrying, the upper surface of the curved cover plate is middle section radian, two sides are symmetrically arranged staight slope
Structure is spent, the stationarity and comfort that vehicle passes through are improved.
The utility model structure is simple, install convenient, and strength and stiffness are high, and stress is clear, applied widely, by the present apparatus
It is placed on the notch of expansion joint, before expansion joint can be protected to install, bridge expanssion joint notch and embedded bar be not by Construction traffic pressure
It is bad, it needs to readjust reinforcing bar when avoiding the installation of later period expansion joint, manpower and time is greatly saved, improves expansion joint and applies
Working medium amount；Pass through the present apparatus, it is ensured that construction site is neat, clean, is conducive to live civilized construction；By the present apparatus, after convenient
Vehicle pass-through during phase notch concrete curing has good promotion prospect.
