Technical field
The present invention relates to the base arrangement of a kind of beam slab, especially one steel reinforced concrete multicell beam slab base plate and processing technique thereof。
Background technology
Steel bridge base plate mostly is steel plate or reinforced concrete floor, also has the mixed base arrangement of employing Effect in Single Cell Box Girder shaped steel。But all steel single monolayer thick steel plate bending strength is little, the base plate volume of reinforced concrete structure is big, and weight is big, construct, transport extremely inconvenient；And the list relative resisting deflection poor performance of chamber steel reinforced concrete base plate, complicated construction technique。
Summary of the invention
The technical problem to be solved in the present invention is to provide the steel reinforced concrete multicell beam slab base plate and processing technique thereof that a kind of processing technique is simple, anti-bending strength good, reliability is high, and multiple rectangular tubes are assembled the structure forming multicell by it。
For solving above-mentioned technical problem, the technical solution used in the present invention 1 is:
A kind of steel reinforced concrete multicell beam slab base plate, described base plate is welded by the rectangular tube of more than 2 laid out in parallel by the joint face between the connector fastening extended transversely through, adjacent rectangle pipe, forms integrative-structure, Pumping concrete in the cavity of each rectangular tube。
The rectangular tube of laid out in parallel along its longitudinally the screwed hole of uniform correspondence or through hole, by the screw rod fastening ganged up, arrange outside the nut at screw rod two ends and be additionally provided with protection decoration cap。
Longitudinal direction at rectangular tube is threaded hole or through hole, then fastens by bolt and nut pair, is finally welded by the connecting sewing between adjacent rectangle pipe, its Stability Analysis of Structures, and processing technique is simple, quick。
Present invention also offers the processing technique of a kind of steel reinforced concrete multicell beam slab base plate, comprise the following steps:
1. by steel plate punching, then by spiral welded pipe or straight line welded tube technological forming pipe, then it is cold-pressed into rectangular tube, or is processed into rectangular tube by cold-drawing technology, finally carry out heat treatment；
2. rectangular tube is arranged side by side, with screw rod traverse by hole corresponding on each rectangular tube, and screw rod two ends is fastened；
3. fillet that rectangular tube clod wash formed is utilized, by the integrally welded structure of connection facade of adjacent two rectangular tubes, finally casting cement concrete in rectangular tube。
In technique scheme, adopt the base plate of multicell, casting cement xoncrete structure, overcome the defect that monolayer all steel steel plate bending strength is little on the one hand, overcome the defect of single chamber steel reinforced concrete base plate immunity to interference poor performance on the other hand, and construction technology is simple。
Adopt having the beneficial effects that of technique scheme generation: the base plate of (1) present invention is many cell structures, the sidewall of rectangular tube is equivalent to the effect of reinforcement, improve the bending strength of base plate, enhance bearing capacity, when the same height of beam slab, the amount of deflection after beam slab load can be reduced, be conducive to the amount of deflection of beam slab to control；(2) concrete is arranged in rectangular steel pipe, form steel hub cement concrete and (namely retrain concrete with outer steel plate, fix concrete, and can not deform, this structure can improve concrete strength 1 times, if interior note C40 concrete, is equivalent to the concrete intensity of C80), concrete intensity can be significantly improved, save making consumption, alleviating deadweight and improve the rigidity of base plate of cement concrete with this；(3) periphery of base plate is steel, eliminates the diseases such as the concrete aging in use procedure, fatigue cracking, significantly extends the service life of base plate, and then extends the service life of bridge；(4) base plate adopting the present invention is easy to process fast, is suitable to industrialized production；(5) present invention Product Green environmental protection, be beneficial to Ecological Construction。

Detailed description of the invention
Referring to Fig. 1 and Fig. 2, base plate described in the base plate in the present embodiment is welded by the rectangular tube 1 of more than 2 laid out in parallel by joint face between the connector fastening extended transversely through, adjacent rectangle pipe, forms integrative-structure, Pumping concrete in the cavity of each rectangular tube。Concrete, the rectangular tube 1 of laid out in parallel along its longitudinally uniform correspondence screwed hole or through hole, fasten by the screw rod 2 ganged up, arrange outside the nut at screw rod two ends and be additionally provided with protection decoration cap 3。Described through hole can be arranged to slotted hole, with reduce rectangular tube connect required precision, improve base plate working (machining) efficiency。
The same side of rectangular tube 1 arranges upper and lower two row's screwed hole or through holes, forms the structure of two row's screw rod fastenings, to strengthen the bonding strength of base plate。
As an alternative embodiment of the invention。The lateral surface of the rectangular tube at base plate two ends is arc-shaped。Namely described base plate is connected fastening by the tube bank that the upper and lower end face of more than 2 laid out in parallel is plane by the screw rod that extends transversely through, and the side of adjacent tube bank is plane, and the lateral surface being positioned at the tube bank at two ends is arc, and this arc and upper and lower end face rounding off。This structure eliminates the defect that stress is concentrated。
Described rectangular tube 1 can be contour, wide, it is also possible to is contour not wide, as when adopting 3 rectangular tubes arranged side by side, the rectangular tube width on both sides is equal, all little compared with middle rectangular tube width。
The processing technique of the present invention is:
1. by steel plate punching, then by spiral welded pipe or straight line welded tube technological forming pipe, then it is cold-pressed into rectangular tube, or is processed into rectangular tube by cold-drawing technology, finally carry out heat treatment；Heat treatment step eliminates stress in pipe forming process。Can also punching again after pipe molding。
2. rectangular tube is arranged side by side, with screw rod traverse by hole corresponding on each rectangular tube, and screw rod two ends is fastened；
3. fillet that rectangular tube clod wash formed is utilized, by the integrally welded structure of connection facade of adjacent two rectangular tubes, finally casting cement concrete in rectangular tube。The present embodiment forms this special shape of fillet after taking full advantage of COLD ROLLING RECTANGULAR pipe molding, it is not necessary to individually bevel for welding is beaten in processing again。
If what need is arch floor, after integrally welded, the camber that base plate clod wash is become required by Large Scale Cold bender can be passed through。The base plate of arch can be greatly improved the opposing load amount of deflection of bridge type, compared with slab bridge, prestressing force can be saved equally when footpath, the base arrangement of the present invention, its arch is adopted to be easily worked, further increase the anti-interference intensity of base plate after pressure injection cement concrete, and the sidewall of rectangular tube is equivalent to the effect of reinforcement。
