Description

Tool type formwork for cement concrete bridge floor

Technical Field

The utility model relates to a cement concrete bridge floor formwork, in particular to cement concrete bridge floor instrument formula formwork.

Background

The concrete bridge deck pavement layer mainly plays a role in protecting a bridge deck, dispersing wheel concentrated load and preventing main beam concrete and steel bars from being corroded, and construction quality control is very important. The traditional method is that after the reinforcing mesh is installed or bound and accepted, a half width is generally divided into 2-3 strips for pouring by utilizing a prefabricated elevation control band, vibration compaction is carried out through a vibrating rod, a flat vibrator, a vibrating beam and the like, surface cement slurry is extracted through a slurry extracting roller, and finally finishing, forming and napping are carried out. The traditional construction method is labor-consuming and time-consuming, the phenomena of poor flatness of a pavement layer, dislocation of a secondary construction surface, large-area cracking and the like often occur, and the construction quality is not easy to control. The thickness of the bridge deck pavement is increased, the overall rigidity of the bridge structure cannot be enhanced generally, but the dead load of the bridge is increased, and particularly for the large-span bridge, the weight of the bridge deck pavement can have great influence on the economy of the bridge. Therefore, it is desirable to have the deck pavement as thin as possible to reduce weight. The bridge can produce the flexure under the vehicle load effect for the deck pavement also produces the flexural deformation, therefore, under the repeated load effect, the deck pavement easily produces fatigue fracture. The good flexibility of the paving material can reduce or avoid the flexural cracking of the paving layer. The elastic modulus of the bridge deck pavement material is generally far smaller than that of a bridge deck slab, a pavement layer is thinner (generally 5-8 cm), and under the action of vehicle load, bridge deck pavement is in a more unfavorable stress state than a common road surface. Particularly in high-temperature seasons, the pavement of asphalt bridge decks is easy to generate plastic deformation and slippage, and waves and ruts are formed. Therefore, the paving material is required to have better deformation resistance stability, and be well adhered to the bridge surface, so as to avoid plastic deformation and slippage. The water seepage of the pavement of the bridge deck can cause the corrosion of steel bars in the steel bridge deck or concrete. Therefore, compared with the common pavement, the water seepage prevention requirement for bridge deck pavement is higher. The smooth bridge deck pavement can meet the requirements of stable and comfortable running of vehicles, reduce the impact effect of vehicle load on a bridge structure, improve the load condition of the bridge and also be beneficial to the drainage of the pavement surface.
