Abstract

The utility model discloses a vibration isolating rubber bearing, which relates to an improvement of the vibration isolating rubber bearing, and is simple in structure and easy to replace and guarantees safety of buildings. The vibration isolating rubber bearing comprises a top plate, a bottom plate and a rubber bearing body, wherein the rubber bearing body is fixedly connected with the top plate, the bottom surface of the rubber bearing body is of a convex cone, the bottom plate is relatively spliced by a pair of semicircular hough plates, and an indented cone which is adopted to the convex cone of the rear surface of the rubber bearing body is arranged on the top surfaces of the semicircular hough plates. The bottom surface of the vibration isolating rubber bearing is of the convex cone, the bottom plate is provided with the indented cone simultaneously, the bottom plate is relatively spliced by a pair of semicircular hough plates, the vibration isolating rubber bearing and the bottom plate are reliably connected, and the vibration isolating rubber bearing is easier to be moved out when being replaced, and falls and is moved out to complete replacement process. The vibration isolating rubber bearing is simple in structure and wide in applicable scope.

Description

A kind of shock insulation rubber bearing

Technical field

The utility model relates to construction engineering technical field, relates in particular to the improvement to shock insulation rubber bearing.

Background technology

Along with society constantly develops, when facing the puzzlement of natural calamity earthquake, traditional seismic measures is the intensity of reinforcement system, and doing had so both increased construction costs, and anti seismic efficiency is also undesirable, and the appearance of shock insulation rubber bearing is the corrective measure of antidetonation.In construction work; Shock insulation rubber bearing normally is fixedly connected on the building bottom girder, is located on the strong point of building, receives the influence of service life; Need regularly change neoprene bearing; Yet in the process of changing, normally be to withstand the building bottom girder, neoprene bearing is shifted out, changes with hydraulic jack.Because the position of neoprene bearing is fixed, so hydraulic jack withstands on when ejecting, causes the distortion of bottom girder easily, jeopardizes the safety of building, and is as shown in Figure 6.

The utility model content

The utility model is to above problem, provide a kind of simple in structure, change and guarantee the shock insulation rubber bearing of building safety easily.

The technical scheme of the utility model is: comprise top board, base plate and be fixedly connected the neoprene bearing body of said top board, the bottom surface of said neoprene bearing body is the evagination conical surface;

To piecing together, said a pair of semicircle Hough plate top surface to assembly is provided with the suitable indent conical surface of the evagination conical surface with said neoprene bearing body bottom surface to said base plate by pair of semicircular shaped Hough plate.

Also comprise down shrouding, said shrouding down is fixedly connected on the bottom surface of said neoprene bearing body, and the said bottom surface of shrouding down is the evagination conical surface two, and the said evagination conical surface two is suitable with the said a pair of indent conical surface to the semicircle Hough plate top surface pieced together.

Be provided with through hole in said a pair of centre position to the semicircle Hough plate pieced together.

The rubber earthquake isolation support of the utility model; The bottom surface of neoprene bearing is set as the evagination conical surface; Simultaneously base plate be provided with the indent conical surface and base plate by pair of semicircular shaped Hough plate to piecing together; Make neoprene bearing be connected with base plate reliably, when changing neoprene bearing, be easy to shift out, neoprene bearing falls and shifts out, and accomplishes the replacing process.The utility model is simple in structure, and is applied widely.

The specific embodiment

The utility model comprises top board 1, base plate 3 and is fixedly connected the neoprene bearing body 2 of said top board 1 that the bottom surface of said neoprene bearing body 2 is the evagination conical surface 21 shown in Fig. 1-5;

Said base plate 3 to piecing together, said a pair ofly is provided with the indent conical surface 31 suitable with the evagination conical surface of said neoprene bearing body 2 bottom surfaces 21 to the semicircle Hough plate top surface of piecing together by pair of semicircular shaped Hough plate.At work, the processing indent conical surface 31 on said base plate 3 is divided into pair of semicircular shaped Hough plate with base plate 3 then earlier.

Also comprise shrouding 20 down; Said shrouding 20 down is fixedly connected on the bottom surface of said neoprene bearing body 2; The bottom surface of said down shrouding 20 is the evagination conical surface 2 22, and the said evagination conical surface 2 22 is suitable with the said a pair of indent conical surface 31 to the semicircle Hough plate top surface pieced together.

Shown in Fig. 2-3, be provided with through hole 32 in said a pair of centre position to the semicircle Hough plate pieced together.

The top board 1 of the utility model is fixedly connected on the building bottom girder 4; Base plate 3 is fixedly connected on the building strong point 5; When changing neoprene bearing body 2, top board 1 and base plate 3 pines are unloaded, with a pair of the semicircle Hough plate of piecing together is shifted out to both sides then; Make neoprene bearing body 2 fall to changing, guaranteed the safety of building.
