Abstract
The utility model relates to a bridge cast steel pressure-bearing seat which can meet the requirements of a cast steel part on strength and toughness and ensure the welding property when the thickness is 200mm. A seat body of the cast steel pressure-bearing seat is a cube, and two cast steel support lugs are symmetrically arranged on the upper end surface of the cube. The bridge cast steel pressure-bearing seat has the advantages that not only the structural requirements of a sea-spanning bridge on the cast steel pressure-bearing seat is met, but also small drag coefficient and good pressure-bearing effect are realized.
Description
Technical field
When the utility model relates to a kind of bridge cast steel Pressure Block thickness and is 200mm, can satisfy intensity and the toughness reguirements of steel-casting, can guarantee again the high creep resistant bridge cast steel Pressure Block of its weldability, belong to bridge cast steel Pressure Block and make the field.
Background technology
CN102535330A, title " a kind of bridge pad ", comprise: lower seat board, the upper surface of described lower seat board is provided with groove, and the bottom surface of described groove is provided with multistage annular groove, described annular groove comprises sipes section and the less narrow slot part of cell wall distance that the cell wall distance is larger successively along the groove depth direction, and the sidewall of described lower seat board offers a plurality of passages of inculcating, and a plurality of described narrow slot part one by one corresponding connection of bottom of inculcating passage and multistage described annular groove; Joint ring, the sipes section of secondary annular groove is provided with two described joint rings, and the number that is provided with described joint ring greater than the sipes section of the annular groove of secondary increases progressively step by step; Sealing mat, but described sealing mat upper and lower displacement be arranged in the described groove, and the sidewall of the outer peripheral face of described sealing mat and described groove keeps sealing; Lower support plate assembly and the upper bracket board component that is supported by described lower support plate assembly, described lower support plate assembly is supported by described sealing mat.Its weak point: the pressure-bearing that is not suitable for the bridge spanning the sea bridge.
The utility model content
Purpose of design: avoid the weak point in the background technology, designing a kind of the utility model, to relate to a kind of thickness be 200mm, can guarantee that the intensity of material and toughness meet design requirement simultaneously, can guarantee again the high creep resistant bridge cast steel Pressure Block of material weldability.
Design scheme: high creep resistant low-temperature high-toughness bridge is that the applicant is the cast steel Pressure Block of this Project design specially in participating in the U.S.'s new Transbay Bridge project construction process with the steel-casting material, this cast steel Pressure Block is according to the designing requirement of bridge to Pressure Block, adopting the cast steel cube is the pressure-bearing pedestal, adopts the symmetric support ear that is integrated with the pressure-bearing pedestal as the supporting bridge point; Air channel between two support ears is to reduce air resistance coefficient; The pedestal side opening is used to perforation, has realized adopting between a plurality of cast steel Pressure Blocks the interconnective purpose of bolt column.
Technical scheme: a kind of high creep resistant bridge cast steel Pressure Block, cast steel Pressure Block pedestal is cube, cubical upper surface symmetry has two cast steel support ears.
The utility model is compared with background technology, not only satisfied the structural requirement of bridge spanning the sea bridge to the cast steel Pressure Block, and air resistance coefficient is little, and pressure-bearing is effective.
Description of drawings
Fig. 1 is the structural representation of cast steel Pressure Block.
Fig. 2 is Fig. 1 side-looking structural representation.
The specific embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.A kind of high creep resistant bridge cast steel Pressure Block, cast steel Pressure Block pedestal is cube 1, the upper surface symmetry of cube 1 has two cast steel support ears 2.Cube 1 side has is used to bore a hole 3, and its manufacture craft is the cast steel moulding process.
What need to understand is: although above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (2)
1. one kind high creep resistant bridge cast steel Pressure Block, it is characterized in that: cast steel Pressure Block pedestal is cube (1), and the upper surface symmetry of cube (1) has two cast steel support ears (2).
