Description

A kind of replaceable prefabricated assembled combined beam structure and manufacturing process
Technical field
The present invention relates to the replaceable prefabricated assembled combined beam structure of one kind and manufacturing process, belong to science of bridge building technology Field.
Background technology
Transportation industry " 13 " planning proposition will actively promote bridge industrialized production, and the development of packaged type bridges is just It is to realize the big approach of bridge industrialized.Country's prefabricated concrete structure is because its construction speed is fast, quality level at present High advantage is used by some engineering projects, but bad because its production cost is higher, difficulty of construction is larger and can not tear down and reconstruct etc. Gesture cannot meet design or construction requirement in many construction styles, greatly limit prefabricated concrete structure Development.
The structural system that steel-concrete composite beam is a kind of girder steel to be combined into armoured concrete slab, relative to not pressing The clean steel bridge of combined structure design, it is considered to which common stress can reduce structure height, improve the rigidity of structure, reduces structure in lotus living Amount of deflection under carrying.And relative to concrete bridge, superstructure height reduction, weight reduction, geological process reduce, structure ductility is carried High, foundation cost reduction.Steel-concrete composite beam has given full play to both advantages, can not only use traditional construction method, And excellent structural behaviour can be obtained by simple construction technology, and obvious technical economic benefit is reached, it is very suitable for The energy-saving and emission-reduction policy that China proposes at present.
The endurance issues for being completed bridge increasingly cause the concern of people, and steel corrosion and concrete cracking are influences The subject matter of durability, it not only affects the service life of structure, also results in substantial amounts of potential safety hazard, or even cause thing Therefore.Wherein, floorings directly bear vehicular load and environmental load, be by overloading, the unfavorable factor such as corrosion and fatigue influenceed most straight The component for connecing, and traditional steel-concrete combination beam cannot quickly carry out the replacing of floorings, it is therefore necessary to floorings Structure is improved, and improves the service life of bridge.
The content of the invention
In order to overcome quick-replaceable deficiency that cannot carry out of existing combined beam structure, the present invention to provide a kind of replaceable Formula, the replaceable prefabricated assembled combined beam structure that construction is simple, efficiency of assembling is higher and manufacturing process.
The technical solution adopted for the present invention to solve the technical problems is:

Further, the precast slab is provided with preformed groove, and the preformed hole is located in the preformed groove.
Further, upper padding plate is placed in the preformed groove, the top flange plate of the precast slab and the girder steel Between lower bolster is set.
Further, the high-strength bolt connector includes shearing bolt, nuts and washers, and the shearing bolt is from upper Under sequentially pass through packing ring on upper padding plate, upper padding plate, preformed hole, lower bolster, the top flange plate of girder steel, positioned at top flange plate It is fastenedly connected with the nut after the packing ring of lower section.
The girder steel top flange plate is set with group's well format, and hole size uses bolt gauge orifice;The lower hole it is big Small, number and arrangement form are consistent with hole set by girder steel top flange.
The shearing bolt uses high intensity friction-type connection, and the nut is Anti-loosening nut or double nut.
The upper padding plate, lower bolster are provided with the preformed hole consistent with precast slab, the upper padding plate, underlay board size In the same size with precast slab preformed groove, the upper padding plate, lower bolster are welded on the steel reinforcement cage in concrete slab, welding Position is identical with reserved groove location.
The precast slab is floorings, and the floorings are a whole plate along bridge cross direction, and multiple is arranged side by side The floorings are set on the top flange plate of the girder steel.
A kind of manufacturing process of replaceable prefabricated assembled combined beam structure, the manufacturing process is comprised the following steps:
Step 1:According to combination beam design conditions, girder steel is arranged;Sandblasting is carried out to girder steel top flange plate upper surface Treatment;
Step 2:Precast slab is lifted to girder steel, it is ensured that all preformed hole alignment and up/down perforation;
Step 3:High-strength bolt connector is passed through into the preformed hole and lower hole, by the precast slab and girder steel Top flange plate is fastened;
Step 4:After all high-strength bolt connectors whole installations after, arrange external prestressing tendon, fasten it is adjacent it Between vertical concrete plate;
Step 5:Treatment of mating formation is carried out to precast slab, combined beam structure is completed and is installed;
If need to be changed to precast slab, by dismantling high-strength bolt connector and external prestressing tendon so that Precast slab is separated with girder steel;Repeat step 2 to step 5, you can complete the assembled again of combined beam structure.
Preferably, the high-strength bolt connector includes shearing bolt, nuts and washers, and the shearing bolt is from top to bottom Sequentially pass through packing ring on upper padding plate, upper padding plate, preformed hole, lower bolster, the top flange plate of girder steel, under top flange plate It is fastenedly connected with the nut after the packing ring of side;In the step 3, packing ring is placed at upper padding plate preformed hole, by shearing bolt 7 Preformed hole is sequentially passed through, fastening is then attached to it using nuts and washers.
Beneficial effects of the present invention are mainly manifested in:
1. the present invention uses high-strength bolt connector, construction is simple, it is to avoid traditional peg shear connector is caused by welding The problems such as fatigue life decline, residual stress, improve the bearing capacity of structure.
2. the present invention uses prefabricated assembled combination beam, all components to be completed in factory process, transport to construction site Afterwards, can assembly connection at the construction field (site), reduce Site Welding work and form work engineering, it is ensured that site operation quality, improve Building industrialization efficiency of assembling.
3. in the present invention floorings using precast block method, girder steel and concrete slab are connected by high intensity friction Type bolt, girder steel top flange is fixed in by tightening nuts.When certain block floorings needs to change, can be by part more The method changed, dismantles the nut on shearing bolt successively so that concrete slab and girder steel are separated, and then realize tearing open for concrete slab Unload separation and change, bridge reaches the effect of side deburring operation simultaneously, greatly reduce because traffic is blocked up caused by bridge maintaining Plug, alleviates traffic pressure.The damaged concrete plate changed is recyclable, reinforce, cycling and reutilization, embody install convenient efficiently, It is easy to tear down and reconstruct the facade lighting and thought with environmental protection and energy saving.
