Abstract
The utility model discloses an air cooling composite structure binding post head. The air cooling composite structure binding post head is characterized in that the air cooling composite structure binding post head is formed by two sliding steel plates, the free sliding distance between the two sliding steel plates is from 30 mm to 50 mm; the air cooling composite structure binding post head is installed between the upper portion of a reinforcing steel bar concrete tubular column and a space steel truss connection node; or the air cooling composite structure binding post head comprises a lower bearing steel plate and an upper bearing steel plate; a sliding plate or a coating is arranged between the lower bearing steel plate and the upper bearing steel plate; the sliding plate or the coating is welded with one contact surfaceof the lower bearing steel plate or the upper bearing steel plate; and the other contact surface is a sliding friction surface. The air cooling composite structure binding post head solves the contradiction, between temperature deformation and earthquake replacement, of an air cooling composite structure, is suitable for both a high-intensity area and a low-intensity area, and can fully ensure quake-proof safety of air-cooling condenser equipment.
Description
Technical field
The utility model relates to a kind of connection column cap, is used for the vertical combination construction of steam power station air cooling reinforced concrete pipe column-steel truss.The connection column cap of utility model can be coordinated the contradiction that in the air cooling structure, temperature deformation and earthquake displacement produce.
Background technology
Air cooling technique is but technology of a kind of novel weary air cooling adopted of present steam power station, and it is than the clammy technique saving water resource 70～80% of traditional Hyperbolic Cooling Towers.Air cooling technique has a wide range of applications in the three northern areas of China of the rich coal lack of water of China.
The air cooling structure is to be accompanied by air cooling technique to occur and a kind of infant industry building structure of formation, is generally the vertical combination construction of reinforced concrete pipe column-steel truss, as shown in Figure 1.Air cooling tubes condenser equipment namely is fixed on A type frame.The air cooling structure forms complicated, is supporting the air cooling tubes condenser equipment of nearly ten thousand tons, in addition, also bears the dynamic load function of Various Complex.
The vertical combination construction of air cooling reinforced concrete pipe column-steel truss is under the common requirement of technique and structural performance, and the reinforced concrete pipe column height in structure reaches 30～40m; Simultaneously, structure is in order to satisfy the requirement of lateral deformation stiffness, and the diameter of tubing string will reach the 4m left and right, and wall thickness reaches 300～500mm.In order to bear heavy weight air cooling tubes condenser equipment, the height of steel truss will reach 5～8m.
In cooling procedure, air cooling tubes condenser produces the temperature difference larger thermal field.Steel Space Truss is arranged in this thermal field, affected by action of thermal difference, can produce significant thermal stresses and distortion.Because thermal stresses requires to discharge, thereby need steel truss and being connected of reinforced concrete pipe column are made the slippage type of attachment; But because will resist geological process, so its connection should be more strong better.So " putting " of thermal stresses just produced contradiction with " resisting " of geological process.
For this reason, be necessary to design a kind of air cooling combination construction and connect column cap, the contradiction that produces to coordinate temperature deformation and earthquake displacement.
Summary of the invention
The purpose of this utility model is to provide a kind of novel air cooling combination construction jointing, and effectively release temperature stress and distortion do not affect again the anti-seismic performance of air cooling structure simultaneously.
To achieve these goals, the utility model is achieved by the following technical solutions:
A kind of air cooling combination construction connects column cap, and it is characterized in that: this connection column cap is comprised of two blocks of slippage steel plates, and the free skidding distance between two blocks of slippage steel plates is 30-50mm; This connection column cap is installed between reinforced concrete pipe column top and Steel Space Truss connected node;
Hold under perhaps this connection column cap comprises steel plate and on hold steel plate, under hold steel plate and on hold and be provided with slide plate or coating between steel plate, slide plate or coating and under hold steel plate or on hold steel plate one of them contact surface welding, another contact surface is the sliding friction face.
The utility model compared with prior art has following technological merit:
(1) solved the contradiction of temperature deformation and earthquake displacement in the air cooling combination construction.
(2) both be applicable to high earthquake intensity area, be applicable to again low earthquake intensity area, and can fully guarantee the quake-resistant safety of air cooling tubes condenser equipment.
Description of drawings
Figure 1 shows that the vertical combination construction of air cooling steel-concrete.
Figure 2 shows that reinforced concrete pipe column top type of attachment.
Figure 3 shows that reinforced concrete pipe column root slip support abutment form.
In figure, each symbol represents respectively following implication: 1, reinforced concrete pipe column, 2, slippage steel plate, 3, Steel Space Truss connected node, 4, hold steel plate on, 5, hold steel plate under, 6, slide plate or coating, a is free skidding distance, the size of a depends on that equipment allows distortion and the deformation values of structure under temperature action.
Below in conjunction with the drawings and specific embodiments, particular content of the present utility model is described further.
The specific embodiment
As shown in Figure 2, for low earthquake intensity area, reinforced concrete pipe column 1 top and Steel Space Truss connected node 3 are made the slippage type of attachment, namely connect column cap and are comprised of two blocks of slippage steel plates 2, and the free skidding distance between two blocks of slippage steel plates 2 is 30-50mm.A certain comb post and being connected to of Steel Space Truss in the air cooling combination construction are rigidly connected, and all the other tubing string column caps all adopt slippage type of attachment shown in Figure 2.After adopting this slippage type of attachment shown in Figure 2, thermal stresses can access part and discharge, and can not produce excessive thermal stresses and distortion in steel truss.Simultaneously, when structure met with geological process, slip support abutment can play isolating affection, thereby its top air cooling tubes condenser equipment was avoided or alleviated earthquake.
As shown in Figure 3, for high earthquake intensity area, make the slippage type of attachment on reinforced concrete pipe column top and Steel Space Truss junction, with low earthquake intensity area; Simultaneously, the sliding isolated bearing form is made at top, reinforced concrete pipe column basis, hold under namely this connection column cap comprises steel plate 5 and on hold steel plate 4, under hold steel plate 5 and on hold and be provided with slide plate or coating 6 between steel plate 4, slide plate or coating 6 with under hold steel plate 5 or on hold steel plate 4 one of them contact surface welding, another contact surface is the sliding friction face.Between rubbing surface, lower friction factor must be arranged, to guarantee isolating affection.
