Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0014] refer to figure 2 , the bridge three-way limiting device of the present invention comprises a base 30 and an inverted L-shaped rigid card falcon made of steel vertical limbs 31 and horizontal limbs 32. The lower end of the vertical limbs 31 is fixedly connected with the base 30 as a whole. The upper end of 31 and the front end of transverse limb 32 have vertical limb ball head 31a and horizontal limb ball head 32a respectively. The device integrates the three-way limit, and can simultaneously limit and buffer the vertical, longitudinal and lateral displacements of the beam body.
[0015] refer to figure 1 and image 3 , The bridge three-way limit shock-absorbing structure of the present invention includes a pier body 20 and a beam body 10 supported on two support pad stones 21 and 22 at the top of the pier body 20 through a support. The base...
