Abstract
The utility model discloses a bridge bearer for controlling lateral force by a resist shearing pin and a bolt group, which comprises an upper seat plate, a lower seat plate, a plane polytetrafluoroethylene slide board which locates between the upper seat plate and the lower seat plate, a ball crown lining board and a spherical surface polytetrafluoroethylene slide board. The lower end of the upper seat plate limit direction is provided with a limited baffle, which is connected by the resist shearing pin, the pre-tight bolt group and the upper seat plate. The utility model adopts assembly type fission structure through the upper seat plate and the limit baffle; the pre-tight bolt group supports bending moment effect; the interference fit resist shearing pin supports the level shearing thrust. When the level thrust is less than the lower limit of the horizontal limit design load, the resist shearing pin is on elasticity operating state, and the side direction constraint is effective; when the level thrust is greater than or equal to the lower limit value and is less than or equal to the upper limit value, the resist shearing pin produces shearing deformation till is destroyed; the side direction constraint lose efficacy; the bridge bearer can be slide without being restricted; accordingly, the utility model protects the bridge structure from being destroyed.

Summary of the invention:
The utility model is intended in the bridge construction design; still the present situation of not having at present the bridge pad that satisfies the spacing direct limit load design of bridge pad side direction; provide a kind of by the shear-pin of employing interference fit and the mode of transfer force of pretension bolt faciation combination; control side direction horizontal force ultimate load effectively; with the function of seismic resistance of realization bearing, thereby the protection bridge construction exempts from the bridge pad of the control lateral force of damage.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of bridge pad of controlling lateral force, comprise upper base plate, plane polytetrafluoroethylene (PTFE) slide plate, spherical crown liner plate, sphere polytetrafluoroethylene (PTFE) slide plate, following seat board, it is characterized in that: the lower end in the spacing direction of upper base plate level both sides is connected with postive stop baffle, and inboard being slidingly matched with following seat board of this postive stop baffle contacts.
Be provided with the shear-pin that bears horizontal shear force between described postive stop baffle and the upper base plate.
Described postive stop baffle and upper base plate are connected and fixed by pretension bolt.
Described shear-pin is located at the postive stop baffle outside, and pretension bolt is located at the postive stop baffle inboard.
Described shear-pin and pretension bolt respectively are arranged to a row along the postive stop baffle length direction.
Described postive stop baffle is connected with the plane stainless steel plate with following seat board contact position, is connected with block arc on the corresponding with it following seat board.
Described block arc and plane stainless steel plate contact surface are connected with slide plate.
The slide plate that the utility model is bonded on the block arc forms the constraint of spacing direction and the guiding of non-spacing direction with the plane stainless steel plate coupling that is welded on the postive stop baffle, and the one side that block arc contacts with postive stop baffle is a convex surface.
The sphere of the utility model spherical crown liner plate down, plane polytetrafluoroethylene (PTFE) slide plate is embedded in spherical crown liner plate upper end, and forms the main slide surface of bridge pad with the plane stainless steel plate coupling that is welded on the upper base plate lower end.
The utility model sphere polytetrafluoroethylene (PTFE) slide plate is positioned at spherical crown liner plate lower end, is embedded in down on the seat board, and forms the spherical rotation slide surface with the sphere corrosion resistant plate coupling that is welded on the spherical crown liner plate sphere.
The utility model makes it have following advantage and beneficial effect owing to adopt above structure:
One; owing to adopted upper base plate and postive stop baffle to adopt modular minute body structure; bear the moment of flexure effect with row's pretension bolt group; the shear-pin of another row's interference fit bears horizontal shear thrust; and the one side that block arc contacts with postive stop baffle is designed to convex surface; make between postive stop baffle and the block arc and remain measures such as consistent at the direction and the arm of force H of arbitrary turned position active force; thereby guaranteed the stressed clear and definite and accuracy calculated of lateral force control structure; control side direction horizontal force ultimate load effectively, thereby protected bridge construction to exempt from damage.
Two, bridge pad the necking of power do not occur by the sphere power transmission, and the counter-force that acts on the concrete is more even.
Three, bridge pad is realized the rotation process of bearing by sphere polytetrafluoroethylene (PTFE) slide plate and the trackslipping of spherical rotation pair that the sphere corrosion resistant plate that is coated on the spherical crown liner plate is formed, and rotating torque is little, and is wear-resisting, corrosion resistance is high.
Four, bridge pad is adapted to wide bridge, curved bridge, gradient bridge, cable stayed bridge and Longspan Bridge especially respectively to the rotating property unanimity.
