Abstract
A buffer chain for preventing the girder falling aims to reduce the impact force of the earthquake on a girder body in strong earthquake and prevents the girder body of a bridge from falling in strong earthquake in the high seismic zone. One end of the buffer chain is connected with one end of a strong chain through a first connecting piece, the buffer chain is formed by connecting a plurality of buffer chain links (6), both ends of the buffer chain are exposed and a main body is covered in a high-strength rubber body (7), the other end of the buffer chain is connected with the girder body or a pier through a first embedded part and a second connecting piece, a chain is formed by connecting a plurality of strong chain links (9), and one end of the chain is connected with the pier or the girder body through a second embedded part and a third connecting piece. In the utility model, the length of the strong chain link of the buffer chain for preventing the girder falling can be adjusted according to the actual requirements in construction, the strength is higher than that of the buffer chain link, and the normal work of the chain links is effectively ensured. The buffer chain links are connected with the strong chain links through strong hook clasps (shackles), and the installation and replacement of the chain are convenient. The buffer chain for preventing the girder falling is connected with embedded components which are embedded in the girder body or the pier (pier top or pier side) through adjusting the hook clasps.
Description
Technical field:
The utility model relates to a kind of bridge and cushion the impact of seismic forces and the device of anti-falling stop beam when earthquake.
Background technology:
In recent years, along with the increasing of country to the infrastructure construction dynamics, bridge and construction work have obtained development at a high speed, all kinds of new structure patterns and functional bridge and construction work continue to bring out, after 512 Wenchuan earthquakes, special mission has been proposed again bridge engineering---to keep basic current requirement at the violent earthquake axle casing.Along with a large amount of construction of bridge, the bridge construction of especially high earthquake zone has proposed more urgent need to the reliability of bridge when shaking doughtily.
The utility model content:
The purpose of this utility model provides a kind of simple in structure, and assembling is changed convenient, the anti-fall beam buffer chain that shockproof properties is good.
The utility model is achieved in that
The anti-fall beam buffer chain of the utility model, one end of buffering chain is connected with an end of Strong chain by first connector, the buffering chain is connected and composed by some buffering chain links 6, expose at its two ends, main body is coated among the high-strength rubber body 7, the other end of buffering chain is connected with beam body or pier with second connector by first built-in fitting, Strong chain is connected and composed by some powerful chain links 9, and its other end is connected with pier or beam body with the 3rd connector by second built-in fitting.
Gapped between the latch closure that buffering chain link 6 is connected, be full of high-strength rubber in the gap.
Described first, second and third connector is made up of powerful shackle and connecting bolt.
Described first and second built-in fitting is made up of the embedded board 2 that is connected, cast-in fixing bolt 1 and attaching nut 3, and embedded board and tension seat 4 are connected, and the hole of tension seat 4 is connected with the connecting bolt of connector.
The utility model makes the suffered seismic forces of beam body can play buffering when violent earthquake, guarantees simultaneously not skid off bridge pier or abutment at violent earthquake back rest body.By taking to fill special high-strength rubber, can guarantee when earthquake, to reduce the percussion of seismic forces to the beam body.
Description of drawings
Fig. 1 is the utility model structural representation
Fig. 2 is I place among Fig. 1, promptly cushions chain link coupling part structure enlarged drawing
Fig. 3 is user mode figure of the present utility model.
The specific embodiment:
Anti-fall beam buffer chain comprises cast-in fixing bolt 1, embedded board 2, attaching nut 3, tension seat 4, buffering chain end adjustment shackle 5, buffering chain link 6, special high-strength rubber 7, powerful shackle 8, powerful chain link 9, Strong chain end adjustment shackle 10.Adopt buffering chain link, powerful chain link as this device main body structure.The buffering chain link is coated with high-strength rubber body 7, and rubber and buffering chain link sulfuration bonding can play cushioning effect when earthquake.
Needs according to buffering capacity between the buffering chain link latch closure keep certain interval, be full of special high-strength rubber in the gap. when earthquake, special high-strength rubber between the latch closure increases whole chain force by compression gradually, has avoided the impact of seismic forces to make the chain strength reduction.
Buffering chain link and powerful chain link design strength are divided into two grades, make the weak link of whole chain be arranged on the buffer chain loop section all the time, guarantee that chain design intensity is within the regional extent of design.The buffering chain link adopts powerful shackle to be connected with powerful chain link, makes things convenient for chain assembling and replacing.Cast-in fixing bolt, embedded board are embedded in beam body or pier, and the tension seat is connected with cast-in fixing bolt by the attaching nut, can accurately guarantee the required precision of installing, and make things convenient for the installation after the construction of bridge and pier and construction are finished again.Buffering chain link, powerful chain link, powerful shackle adopt buffering chain end to adjust shackle or Strong chain end adjustment shackle is connected with the tension seat.
