Description

A kind of SCS bridge deck of built-in multiple connecting structure

Technical field

The utility model relates to a kind of bridge deck, particularly relates to a kind of SCS bridge deck of built-in multiple connecting structure.

Background technology

Sandwich steel sheet concrete (steel-concrete-steel, be called for short SCS)) combining structure, also claim SCS steel plate concrete structure, be by two block plates and build steel that the concrete between two block plates in interlayer formed-mix combining structure.Invar and concrete bi-material make up weakness each other mutually, give full play to strong point each other, and SCS steel plate concrete structure has very high bearing capacity and excellent mechanical property.Therefore, SCS steel plate concrete structure will ocean platform with greatly across structures such as, heavy duty, light bridges in obtain and apply more and more widely.

At present, the bridge deck used are mostly concrete slab.In actual use procedure, there is following defect in concrete slab: the first, from great, limits structure and the size of lower support pier body; The second, be connected with the main load steel structure of bridge (as the steel work such as plate girder or steel box-girder spandrel girder) to needing bottom concrete slab, and switching performance between steel work and concrete is poor, need to use a large amount of shear connectors, steel using amount is larger; Three, owing to standing dynamic loading throughout the year, having the greatest impact suffered by the top of bridge deck and bottom, very easily there is crack in the bottom of concrete slab, finally causes concrete slab to destroy.Due to above reason, the development and apply of concrete slab is restricted.Thus, corresponding improvement need be carried out to the structure of existing bridge deck.

Summary of the invention

For defect of the prior art and deficiency, the purpose of this utility model is to provide a kind of SCS steel plate concrete bridge deck of built-in multiple connecting structure, its structure is simple, reasonable in design, easy construction and result of use is good, good mechanical performance, effectively can solve that existing concrete bridge deck exist from great, cost is high, the problem such as fragile.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of SCS bridge deck of built-in multiple connecting structure, the concrete structure comprising the first bridge deck, the second bridge deck and be cast between the first bridge deck and the second bridge deck, arranges shearing resistance at the first bridge deck and the intersection of concrete structure and/or the intersection of the second bridge deck and concrete structure and constructs;

Described shearing resistance structure comprises WELDING STUDS and bolt.

Concrete, along the direction perpendicular to bridge deck, shearing resistance is set at the first bridge deck and the intersection of concrete structure and/or the intersection of the second bridge deck and concrete structure and constructs.

More specifically, described bolt connects the second bridge deck, concrete structure and the first bridge deck and is fixed, and bolt and WELDING STUDS are arranged alternately.

Concrete again, the distance between adjacent WELDING STUDS and bolt is 30 ~ 50cm, and the spacing of adjacent bolt is 50cm ~ 80cm.

Further, described WELDING STUDS length is 1/5 ~ 1/3 of bridge deck thickness.

Or the thickness of bridge deck is 30 ~ 60cm, the height of bolt is 32cm ~ 62cm, and the height of WELDING STUDS is 10 ~ 20cm.

In addition, WELDING STUDS diameter is 3 ~ 6cm, and the diameter of bolt is 3 ~ 6cm.

Advantage of the present utility model is:

(1) the SCS bridge deck of built-in multiple connecting structure of the present utility model, specifically intert on SCS bridge deck and bolt component and WELDING STUDS are set, high strength exploitation is owing to remaining that between plate contact surface, frictional force is not overcome and Relative sliding does not occur, thus its globality and good rigidity, be out of shape little, reliably stressed, endurance; WELDING STUDS adopts impact force, utilizes special holdfast that WELDING STUDS is connected with steel plate, can not produce burn to profiled sheet; The premium properties of high-strength bolt can be given full play to, its switching performance can not be weakened again;

(2) bridge deck of the present utility model have worn two kinds of connecting structure, the setting of WELDING STUDS decreases the pore quantity of the first bridge deck, decreases the stress raisers phenomenon that hole brings; The setting of high-strength bolt simultaneously compensate for the shortcoming of WELDING STUDS strength deficiency, and both have complementary advantages, and common cooperation realizes bridge deck strength support;

(3) structure simple, reasonable in design and drop into construction cost lower, cheap, can be prefabricated in the factory, process easy and process velocity fast, greatly reduce the time of site operation, improve the efficiency of construction, good mechanical performance and result of use is good, have the advantage of steel and reinforced concrete structure concurrently, in opposing impact load and explosive load, all there is good performance, there is very high bearing capacity;

(4) from heavy and light, effectively be connected with the vertical connecting structure of building in light-concrete structure by light-concrete structure between first bridge deck and the second bridge deck, effectively reduce the overall weight of bridge deck to a great extent, make SCS steel plate concrete structure can obtain fully, effectively playing as the advantage of bridge deck, prefabricatedly add man-hour, effectively can reduce the use of template, cost-saving, reduce manpower and materials, and substantially increase the flexibility of construction.
