A kind of U-shaped flitch beam of monoblock type clod wash steel plate
Technical field
The present invention relates to a kind of U-shaped flitch beam of monoblock type clod wash steel plate, in particular to U-shaped rib and concrete slab Connection type belongs to the technical field of civil engineering.
Background technique
The Mid and minor spans plate girder of reinforced concrete bridge of military service many years is under action of long-term load it is possible that beam bottom tension Cracking, furthermore web easily occurs diagonal crack when being acted on by curved scissors, the harm influence bridge of these concrete slab beam bridges it is durable Property and safety.For the beam bottom and cracking in webs disease for reducing rc beam bridge, steel-concrete combined structure bridge can be used, increase The tensile property of strong bottom beam body and the curved scissors performance of web.
Composite structure can be high, light-weight using the intensity of steel, the compressive property height of concrete, cheap feature, It is widely used in bridge structure.By taking i shaped steel and concrete composite beam bridge as an example, i shaped steel top flange setting shearing Connector, shear connector Transducers Embedded in Concrete floorings realize that steel is closely connect with concrete.However, i shaped steel is usually by steel Plate welding fabrication, and the arrangement of shear connector is generally welded to connect, and solder joint is more, complex process.Welding There may be defects for process, weld near zone and are also easy to produce welding residual stress, also easily occur stress concentration at welding point, It is unfavorable for the anti-fatigue performance of composite beam bridge.
More for previous Mid and minor spans plate girder of reinforced concrete bridge cracking disease, shaped steel combination beam bridge solder joint is more, work The deficiencies of skill is complicated, the present invention proposes a kind of monoblock type clod wash steel plate U-shaped board compoboard beam bridge without welding, medium and small to enhance Performance is cut in the bending resistance of across footpath plate girder bridge, improves durability and the safety of beam body;Simultaneously compared to welding fashioned iron combination bridge Beam can optimize steel and concrete interface connection type and Joining Technology.
Summary of the invention
The technical problem to be solved in the invention is in view of the above shortcomings of the prior art, and to propose a kind of without welding Monoblock type clod wash steel plate U-shaped board beam bridge, cuts performance to enhance the bending resistance of Mid and minor spans plate girder bridge, improves the durability and peace of beam body Quan Xing;Optimize steel and concrete connection type, improves welding residual stress, connector stress collection that combined bridge is likely to occur and neutralize Fatigue problem.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
A kind of U-shaped flitch beam of monoblock type clod wash steel plate is the clod wash U-shaped steel plate of U-shaped, several clod washes including several sections U-shaped steel plate is arranged side by side, and has connecting plate between the U-shaped edges of plate of adjacent two clod washes, if offering on the connecting plate Dry reinforced hole offers web hole on the side wall of the clod wash U-shaped steel plate, the abdomen on several clod wash U-shaped steel plate side walls Lath hole, which is provided with, extends transversely through reinforcing bar, and the top of clod wash U-shaped steel plate is equipped with lateral connection reinforcing bar, it is described extend transversely through reinforcing bar with It is provided with several vertically through reinforcing bar between lateral connection reinforcing bar, part vertically passes through reinforced hole through reinforcing bar.
Scheme as a further preference is additionally provided on the connecting plate and pours a hole, and part is vertically worn through reinforcing bar It crosses and pours a hole.
Scheme as a further preference, in the clod wash U-shaped steel plate, between two neighboring clod wash U-shaped steel plate and even Fishplate bar top is filled with concrete, and the concrete covers lateral connection reinforcing bar.
A kind of technique of the U-shaped flitch beam of monoblock type clod wash steel plate, which comprises the following steps:
Step 1: making steel plate in factory first, and in predeterminated position aperture, formation pours a hole, web hole, reinforced hole;
Step 2: the steel plate after aperture is fabricated to by clod wash U-shaped steel plate by cold bending process;
Step 3: the clod wash U-shaped steel plate of monoblock type is transported to construction site, erection is welded side by side in place, the cloth on U-shaped steel plate Set the template for casting concrete;
Step 4: reinforcing bar vertically through reinforcing bar and is extended transversely through through installation by preset hole, then arranges lateral connection steel Muscle;
Step 5: finally from pouring a hole casting concrete, and molding is conserved.
Compared with prior art, a kind of U-shaped flitch beam of monoblock type clod wash steel plate of the invention is realized U-shaped steel plate and is mixed Solidifying soil floorings are combined closely, and such bridge structure entirety welding seam, the complicated technology and welding for avoiding welding can Energy bring fatigue disease, optimizes the connection type of compoboard beam bridge;Monoblock type clod wash U-shaped steel plate simple process is made, it can Prefabrication;Suitable for integral cast-in-situ, bridge structure good integrity, it is convenient to construct.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention;
Wherein, 1- clod wash U-shaped steel plate, 2- pour a hole, 3- web hole, 4- reinforced hole, and 5- vertically runs through reinforcing bar, and 6- is laterally passed through Wear reinforcing bar, 7- lateral connection reinforcing bar, 8- concrete.
