Description
Technical field
The utility model relates to temporarily driving belongs to bridge construction mistake by device at a kind of notch of novel bridge expansion joint
Notch protective device technical field in expansion joint in journey.
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 driving is logical at a kind of this novel bridge expansion joint notch
Device is crossed, 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 novel bridge is stretched
Temporarily driving is by device at contracting slot mouth, it is arranged on the expansion joint notch of girder, including shape steel support, in fashioned iron branch
The top of support is equipped with rectangular steel plates, and both ends are fixed with corner block, and rectangular steel plates and corner block upper surface, shape steel support
It is concordant transition with corner block lower surface, the shape steel support includes two I-steel girders, the two of I-steel girder
End and medium position are equipped with the junction steel plate for being connected and fixed two I-steel girders.
Aforementioned corner block is connected in the both ends of shape steel support by bolt.
Aforementioned corner block is the overall structure that the lumps of wood is processed into.
Anti-skidding horizontal stripe is equipped in the upper surface of aforementioned corner block.
Compared with the prior art, the utility model, which discloses temporarily to drive a vehicle at a kind of notch of novel bridge expansion joint, passes through dress
It sets, including shape steel support, is equipped with rectangular steel plates at the top of shape steel support, both ends are fixed with corner block, shape steel support
For the main bearing carrier of vehicle pass-through, including two I-steel girders, both ends and medium position are equipped with junction steel plate, pass through
Two I-steel girders can be connected by junction steel plate, and rectangular steel plates and two corner blocks constitute interim vehicle pass-through vehicle face, institute
The top that rectangular steel plates are connected in shape steel support is stated, this overall structure is high-strength steel sheet, and strength and stiffness are good, service life
Height, in order to reduce processing cost, at shape steel support both ends, the installation lumps of wood is processed into corner block, and the two is connected using bolt
It connects, dismounts, repairs, replacing, convenient in carrying.
The utility model structure is simple, easy to use, be laid at the notch of expansion joint by elder generation geotextiles prevent clast and
Sundries falls into beam-ends gap, then places the present apparatus on the notch of expansion joint, before expansion joint can be protected to install, bridge expanssion joint notch
And embedded bar is not damaged by pressure by Construction traffic, needs to readjust reinforcing bar when avoiding the installation of later period expansion joint, be greatly saved
Manpower and time improve expansion joint construction quality；Pass through the present apparatus, it is ensured that construction site is neat, clean, is conducive to scene text
Bright construction；By the present apparatus, facilitate vehicle pass-through during later period notch concrete curing, there is good promotion prospect；In addition,
Shape steel support, rectangular steel plates and corner block are easily manufactured, optimize manufacturing process, and corner block is timber manufacture, manufacturing cost
It is low, there is good economic and practical.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Fig. 2 is the positive structure schematic of the utility model.
Fig. 3 is the top surface structure schematic diagram of the utility model.
