Abstract
The utility model discloses a steel skeleton construction used for concrete dam which is formed by connecting a plurality of unit structure in same along length direction of the dam. The unit structure includes a water face frame constituted by sectional steel mainly comprising steel I-beam, angle iron and channel beam, and an air face frame which is connected with the water face frame by a steel truss. Under covered bulk concrete, bending force and shear resistant force of the utility model will exceed 2-3 times from reinforced concrete structure, shockresistant intensity can increase 1-2 earthquake magnitude, consumption of steel can reduce more than 1/3 to developing new aspect for constructing the dam.
Description
Technical field
The utility model relates to the steel skeleton construction that a kind of concrete dam is used.
Background technology
At present concrete dam what construct employing all is reinforced concrete structure, this structure is formed by connecting by reinforcing bar owing to inner skeleton, its shearing resistance bending resistance is limited, steel consumption is big, must wait concrete to reach certain intensity during construction and could continue construction, so the duration is longer, and scattered site operation amount is big, faces and builds the expense height.
The utility model content
The steel skeleton construction that provides a kind of concrete dam to use is provided the purpose of this utility model, makes up expense height, long in time limit, shearing resistance bending resistance more weak problem relatively to solve present steel concrete dam.
The steel skeleton construction that the utility model concrete dam is used is formed by connecting along the dam length direction by a plurality of identical block constructions, described block construction comprises upstream face framework and the back side framework of forming based on the shaped steel of i iron, angle steel, channel-section steel, forms so that steel truss is continuous between two frameworks.
Because what the upstream face framework of the utility model steel skeleton construction and back side framework adopted is i iron, angle steel, channel-section steel is main shaped steel, consider from the angle of the mechanics of materials, shaped steel particularly i iron in resistance to bending, the shearing resistance aspect is all more superior than reinforcing bar, especially under the concrete in mass parcel, be subjected to curved power and shearing resistance to surpass reinforced concrete structure 2-3 doubly, based on this principle, we are mainly being bent, cut direction and arranged i iron, other arranges channel-section steel on less important positions such as component, steel plate and angle steel, reinforcing bar in the prior art is cemented out, can reduce by 1/3 above steel.The dam that uses the utility model to build up also has good anti-seismic performance, compares its shock strength with the dam of steel-concrete structure and can improve 1-2 earthquake magnitude, and this is because steel reinforced concrete structure is better than the ductility of steel concrete.The utility model adopts batch production to make, on-the-spot then the installation, can reduce to face to build and execute, and because the shaped steel itself in the utility model has very big supporting capacity, above large-scale punching block can directly be welded on, and construction the time needn't wait concrete to reach certain intensity to continue construction again, therefore can reduce technology off time, shortens the construction time limit greatly.The utility model is actually the mature technology of the formed steel construction in steel and the concrete combined structure in the worker China Democratic National Construction Association field is applied in the building a dam of hydraulic architecture field, so its reliability is not have to hold to query.

The specific embodiment
Embodiment one: this is a kind of steel skeleton construction that the utility model is used for gravity dam.As can be seen from the figure to be used for the steel skeleton construction of gravity dam be to be formed by connecting along the dam length direction by a plurality of identical block constructions to present embodiment, Fig. 1 and Fig. 2 have reflected its structure, each block construction comprises between upstream face framework 1 and back side framework 2, two frameworks and linking to each other with steel truss 3; Upstream face framework 1 comprises big i iron column 11, and its positive and negative two vertical surfaces (111,112) are connected with the big i iron column of adjacent cells with steel plate or channel-section steel 12; Back side framework 2 is formed by connecting by the multistage girder construction that reduces step by step along back side, this girder construction comprises i iron crossbeam 21, i iron column 22, there is the distribution channel-section steel 23 of vertical layout on one side of i iron crossbeam 21, the another side one end i iron column 22 of ining succession, the in succession i iron column of adjacent cells of the other end, fixedly connected with high-strength bolt earlier during connection, again with two-sided groove welding, especially big i iron column, must weld by two-sided groove between some main parts such as i iron crossbeam, to big i iron column according to the stressing conditions feature can model be from large to small from top to bottom with uniform variable force, the kind of the selected shaped steel of size of steel truss and model are fixed through accurately calculating by actual conditions, to the i iron column in the multistage girder construction of back side framework 2, the model of I-shaped crossbeam and distribution channel-section steel is then unanimous between the higher and lower levels.
Embodiment two: be a kind of steel skeleton construction that the utility model is used for arch dam.Its structure and embodiment one are basic identical.Plan view shape of the present utility model as can be seen from Figure 3 is fan-shaped, and the big i iron column 11 of upstream face framework 1 and the i iron column 22 of back side framework 2 are arranged on the same radial alignment in every unit.
