Adopt the thermal rolling steel plate owing to constitute the major structure of this support, its machinability, material percentage elongation after fracture and shock absorption function power is far above the steel -casting, and it is inside can not to appear the gas pocket again, press from both sides mass defects such as sediment, shrinkage cavity, crackle, has improved product quality and life, has reduced the cost of manufacture and trade and have the installation and maintain and change convenient characteristics.
Description
Technical field
The utility model belongs to the technical field of bridge pad, has and relates to the high-strength spherical support seat that a kind of main body adopts hot rolled steel plate materials processing.
Background technology
Spherical bearing is a kind of novel bridge bearing grown up on the basis of pot rubber bearing, be widely used in bridge or space truss structure engineering, spherical bearing has the advantages such as vertical power transmission is even, rotating torque is little, rotational angle is large, low temperature resistant, ageing-resistant.The complicated structure of the upper and lower support plate of current spherical bearing, particularly lower support plate structure, position, its underpart is square, top is cylindrical or other labyrinth, so all adopt cast steel structure; And steel-casting is when casting, unavoidablely there will be the mass defects such as pore, slag inclusion, shrinkage cavity, crackle, even if adopt the means such as ultrasonic testing/ ultrasonic examination to detect, its inner quality problems existed also have certain Unpredictability, and the intensity of cast steel is difficult to meet the demands sometimes.And at present the bridge pad of cast structure is as the important coupling components of bridge and pier, particularly especially big tonnage bearing, once use, changes very difficult, and the traffic safety of top vehicle can be affected again in Renewal process, the therefore bearing difficulty that there is installation, maintenance and remove stage makeup and costume.
Utility model content
The purpose of this utility model proposes a kind of rational in infrastructure exactly, the high-strength spherical support seat of installation, convenient maintenance.
The technical scheme realizing above-mentioned the utility model object is:
A kind of high-strength spherical support seat, comprises upper bracket board component, arc hat body liner plate and lower support plate assembly; It is characterized in that: the base plate that described lower support plate assembly is made up respectively of hot rolled steel plate and arcs of recesses hat body seat board are formed, and both centers are provided with pin-and-hole, and in this pin-and-hole, are provided with the straight pin of location connection.
The additional technical feature forming above-mentioned a kind of high-strength spherical support seat also comprises:
---described upper bracket board component is made up of top board and the positive stop being arranged at both sides, downside, is provided with plane slide plate, is provided with some reinforcing ribs between outside and described top board inside described positive stop;
---the two sides of described arc hat body seat board are provided with side draw runner;
---described arc hat body is ball-crown body or cylindrical construction;
---described pin-and-hole and corresponding straight pin are at least one.
High-strength spherical support seat provided by the utility model compared with prior art, have the following advantages: one, because the lower support plate assembly forming this bearing is assembled together by straight pin by arcs of recesses hat body seat board and base plate, and the main element of whole bearing all adopts hot rolled steel plate to process, not only make the installation, maintenance of bearing and change convenient, and the mass defect such as pore, slag inclusion, shrinkage cavity, crackle can not be there is again due to its inside, effectively ensure that the quality of product, improve its application life, greatly reduce material cost simultaneously; Its two, because the two sides forming arc hat body seat board are provided with side draw runner and are arranged at plane slide plate set inside positive stop and form horizontal slip friction pair, reduce the frictional resistance in bearing slipping.
Accompanying drawing explanation
Fig. 1: for forming the structural representation of the spherical bearing of high strength;
Fig. 2: be the structural representation of the inner and outer sleeves of pie graph 1.
Detailed description of the invention
Be described in further details below in conjunction with the structure of accompanying drawing to the spherical bearing of high strength provided by the utility model.
As shown in Figure 1, 2, for forming the structural representation of high-strength spherical support seat.Form this high-strength spherical support seat structure to be made up of upper bracket board component 1, plane slide plate 2, spherical crown liner plate 3, sphere slide plate 4 and lower support plate assembly 5.Wherein the bottom surface of upper bracket plate 1 and the side of positive stop 13 are welded by corrosion resistant plate 8 and stainless steel strip 7 respectively, plane slide plate 2 is embedded in the groove of spherical crown liner plate 3, plane slide plate 2 adopts low friction high abrasion resisting material to make, form sliding friction pair with the stainless steel slide plate 8 being fixed on top board 11 downside forming upper bracket board component 1, the horizontal movement of bearing can be realized.Sphere slide plate 4 is embedded in the spherical groove of lower support plate assembly 5, and the spheric pivoting friction pair in a pair with spherical crown liner plate 3, can realize the vertical rotating of bearing.Positive stop 13 and lower support plate assembly 5 define trip and construct, limit the displacement in a direction of bearing, bearing is made to produce the function of unidirectional slippage, the two sides, top of lower support plate assembly 5 are provided with side direction draw runner 6, side direction draw runner 6 and the stainless steel draw runner 7 be fixed on inside positive stop form horizontal slip friction pair, reduce the frictional resistance in bearing slipping.
Can be formed by hot rolled steel plate manufacture completely to realize support body material, complete the constraint breaking away from traditional casting material, the upper bracket board component 1 of this high-strength spherical support seat divide into top board 11, positive stop 13 and is arranged at some reinforcing ribs 12 3 part outside this block and between top board, three is overall by being welded into one, reinforcing rib 12 plays a part to strengthen, meet the requirement of bearing horizontal force, both structural strength was enhanced, in turn save the use of material, the cost of goods manufactured that can well control.
The lower support plate of this high-strength spherical support seat is designed to split type, namely lower support plate assembly 5 is by recessed spherical crown seat board 51, base plate 52 and the pin-and-hole 54 in centre being arranged at both, and in this pin-and-hole, be provided with straight pin 53 form, this straight pin 53 plays the effect that location connects, can well horizontal applied force be delivered in substructure, the labyrinth of traditional lower support plate simplifies by such split-type design, has been convenient to processing and manufacturing, without the need to adopting casting material again.
In addition, in the structure of above-mentioned high-strength spherical support seat, form above-mentioned hat body seat board 51 arc hat body and the hat dignity of arc hat body liner plate of correspondence be spherical (namely bearing is square structure) or rectangle structure as shown in Figure 1; When for rectangle structure, above-mentioned corresponding surface is cylindrical construction; When bearing is one for square structure is the pin-and-hole that its correspondence is arranged at the center of the base plate be made up respectively of hot rolled steel plate and arcs of recesses hat body seat board, and when for rectangle structure, its pin-and-hole is then two, three or more structure.
The utility model is compared with traditional spherical bearing, agent structure all adopts hot rolled steel plate, its workability, material elongation after fracture and impact absorbing energy ability are far above steel-casting, the mass defect such as pore, slag inclusion, shrinkage cavity, crackle can not be there is again in its inside, and price is less than the half of steel-casting, the direct manufacturing cost of product also only has about 2/3 of traditional product.
