Abstract
A pier structure with a case-type combined section has the characteristics of high strength, economical and simple section and easiness in construction. Four post limbs and a reinforced concrete web (20) which is connected between the four post limbs form a case-type section, wherein the post limbs consist of reinforced concrete post limbs (10) and reinforced concrete layers (11) coating the reinforced concrete post limbs (10).
Description
Technical field
The utility model relates to bridge, particularly a kind of bridge pier cross section structure structure of steel pipe and concrete combination.
Background technology
The bridge pressurized, be subjected to bar bending concrete box type structural element, its web thickness and length must satisfy a kind of structure requirement, and its chamfer dimesion must satisfy the local stress requirement.Therefore, the steel concrete box member of design, when the girder span is big, or bridge pier pier height is when very high, the design section size is very big, when concrete shrinkage and creep takes place, causes bridge reinforcement concrete component cracking, simultaneously, the construction costs height, this has been more bridge engineering practice lesson proof.The box compound section structure of exploitation utility model is the inevitable requirement of mountain area bridge technology development.
The utility model content
Technical problem to be solved in the utility model provides a kind of box compound section bridge pier structure, and it is simple and be easy to construction characteristic to have an intensity height, cross section economy.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Box of the present utility model compound section bridge pier structure is characterized in that: it constitutes box-type section by the steel concrete web that is connected between 4 post limbs and post limb, and described post limb is made of the reinforced concrete floor of steel core concrete column limb and outsourcing.
The beneficial effects of the utility model are, cross-sectional strength height, size are little, in light weight, with adopting saving, for high Dun Dakuaqiaoliang provides technology path, have reduced engineering cost
Description of drawings
This manual comprises as next width of cloth accompanying drawing:
Fig. 1 is the cross sectional representation of the utility model box compound section bridge pier structure;
Component shown in the figure, toponym and pairing mark: steel core concrete column limb 10, reinforced concrete floor 11, steel concrete web 20.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, box of the present utility model compound section bridge pier structure, it constitutes box-type section by the steel concrete web 20 that is connected between 4 post limbs and post limb, and described post limb is made of the reinforced concrete floor 11 of steel core concrete column limb 10 and outsourcing.Promptly adopt the cross section group body of concrete filled steel tube, give full play to that concrete filled steel tube intensity height, ductility are good, the characteristics of easy construction as pressurized.Adopt the topping of outsourcing reinforced concrete floor 11 at steel core concrete column limb 10,, formed the novel box compound section structure of concrete filled steel tube and steel concrete simultaneously as the connection web of joint pin limb as steel pipe.Because steel core concrete column limb 10 intensity height are carrying main bodys, steel concrete web 20 sizes that connect between the post limb can be designed to thin cross section, have reduced sectional dimension, can alleviate dead load effectively and save the bridge cost.
The utility model provides new technology path for building high pier and long span bridge beam.
Some principles of the above the utility model box compound section bridge pier structure that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
