Abstract
The utility model relates to a shockproof drawproof unit for bridge, in particular to a shockproof draw unit with an upper bearing plate and a lower bearing plate, which is arranged on a support base or a shearing force tenon. The external surfaces of the upper bearing plate and the lower bearing plate are formed into an upper clamping surface and a lower clamping surface respectively and a drawproof plate is arranged on the two sides of the support base or the shearing force tenon differently from the shearing force direction borne respectively. The two ends of the top and bottom of the drawproof plate are corresponding pressed in and an upper embedded section and a lower embedded section are arranged on the upper clamping surface and the lower clamping surface respectively, further the upper embedded section is an arc surface corresponding to the upper clamping surface in order to support the upper bearing plate and the lower bearing plate of the support base or the shearing force tenon. The upper bearing plate can slip along the arc surface of the drawproof plate due to relative sliding caused by shearing force, therefore the bullish force caused by the sliding of the support base or the shearing force tenon can be removed.
Description
Technical field
The utility model relates to the shockproof anti-pulling device of a kind of bridge, refers in particular to a kind of can effectively preventing of bridging technical field of civil engineering and produces the shockproof anti-pulling device of the power that raises up that is produced when sliding between supporting seat or shearing tenon owing to shearing.
Background technology
As everyone knows, general elevated road, railway or bridge etc., mostly be to utilize many bridge pier to support, be equipped with bridge plate and pieced together to establish and form to be matched with the bridge pier uplink, and for increasing the safety of bridge, as shown in Figure 4, be that each links with an end of two bridge plates 40 respectively at the two ends of a bridge pier 41, each is installed and is provided with a movable and fixed disc type supporting seat 50 and respectively at the both sides of 40 of this bridge pier 41 and two bridge plates, transverse shearing force and shaking force with prevent bridge pier 41 and 40 bridge long side directions of bridge plate, and be matched with 50 of two disc type supporting seats and respectively be provided with a shearing tenon 60, with the horizontal pendulum power and the shearing of 40 bridge two side directions of bridge pier 41 and bridge plate of preventing.
But still have its disappearance on the above-mentioned known bridge, therefore on use is implemented, have the scarce fraud of being taken off at least as the back:
Though known bridge can utilize this supporting seat and shearing tenon, be provided with a upper and lower bearing plate that can produce sliding phenomenon mutually, evenly to bear the shearing and the shaking force of different directions respectively, still, when utilizing supporting seat and shearing tenon, upper and lower bearing plate produces under the situation of relative sliding action, it is excessive to form upper and lower bearing plate possibility slip angle, forms the power that raises up, and causes slip unstable, even bridge plate and bridge pier excessive the rocking of generation relatively, form the not good problem of safety.
Therefore, spirit of studying intensively utility model of the design people is set about research and development, and with professional experiences and gains in depth of comprehension for many years, concentrated test is weeded out the old and bring forth the new, and then proposes the utility model, in the hope of improving known scarce fraud.
The utility model content
Main purpose of the present utility model is for a kind of power that raises up of can effectively prevent this supporting seat and shearing tenon being provided, increasing the shockproof anti-pulling device of bridge of bridge security.
For achieving the above object, the utility model provides a kind of bridge shockproof anti-pulling device, it comprises: a upper and lower bearing plate, each is equipped with a flange outwardly this upper and lower bearing plate in the opposite end, each is formed with a storage tank with corresponding bridge plate and bridge and make two flanges, and two these storage tanks respectively and be formed with a upper and lower folder face between the flange of upper and lower bearing plate; Two are located at the different anti-pulling plate that is subjected to the shearing direction of this upper and lower bearing plate respectively, this anti-pulling Ban Ding, two ends, the end are placed in the storage tank of this upper and lower bearing plate each relatively, and respectively be provided with a upper and lower fitting portion, and should go up face that fitting portion corresponding clip presses the folder face and establish and be an arc surface, for two anti-pulling plates can clamping between these upper and lower bearing plate both sides.
Wherein lock at least between this time bearing plate and this anti-pulling plate and be provided with a bolt.
The shockproof anti-pulling device of this bridge is when producing sliding phenomenon, and this upper and lower fitting portion is the upper and lower bearing plate of clamping effectively, and utilizes the arc surface of fitting portion on this, can slide for going up bearing plate, and then increase the stability and the safety of bridge.
By above-mentioned structure as can be known, the shockproof anti-pulling device of the utility model bridge, have following advantage: the utility model utilization differs from supporting seat or shearing tenon and is subjected to the shearing direction respectively to be folded with an anti-pulling plate, and the last fitting portion of this anti-pulling plate on this on bearing plate the face of folder face contact surface establish and be arc surface, can can slide along the arc surface of this anti-pulling plate for the last folder face of bearing plate on this, and then reach the anti-power of raising up of bearing plate and bridge plate on this, increase the stability of bridge plate and reduce shaking force.
