GVZ圓形板式橡膠支座廠家

橡膠墊塊是由多層橡膠片硫化粘合而成一種普通橡膠支座產品,這種產品具有足夠的豎向剛度,能夠將支座上部構造的反力可靠的傳遞給墩臺,支座具有良好的彈性,以應對橋梁的梁端的轉動;又有較大的剪切變形能力，以滿足上部構造的水平位移。
The rubber pad is composed of multilayer rubber vulcanization bonding a common rubber bearing products, this product has enough vertical stiffness, can force reliable transfer to the pier upper bearing structure, bearing has good flexibility, rotating beam end in response to the bridge; and a larger shear deformation capacity in order to meet, the horizontal displacement of superstructure.
橡膠墊塊的布置
The arrangement of rubber padding blocks
橡膠墊塊的布置主要和橋梁的結構形式有關。通常在布置支座時需要考慮以下的基本原則:
The layout of the rubber pad is mainly related to the structural form of the bridge. The following basic principles should usually be taken into consideration in the arrangement of support:
(1)上部結構是空間結構時，橡膠墊塊應能同時適應橋梁順橋向(X方向)和橫橋向(Y方向)的變形;
(1) when the superstructure is a spatial structure, the rubber pad should be able to adapt to the deformation of the bridge direction (X direction) and the transverse bridge (Y direction).

(2)橡膠墊塊必須能可靠的傳遞垂直和水平反力;
(2) the rubber pad must be able to reliably transfer the vertical and horizontal forces.
(3)橡膠墊塊應使由于梁體變形所產生的縱向位移、橫向位移和縱、恒向轉角應盡可能不受約束;
(3) the rubber block should make the longitudinal displacement, the lateral displacement and the longitudinal and constant angle due to the deformation of the beam body as far as possible.
(4)當橋梁位于平坡上，固定橡膠墊塊宜設在主要行車方向的前端橋臺上;
(4) when the bridge is located on the flat slope, the fixed rubber pad should be located on the front end abutment of the main driving direction.
(5)橡膠墊塊宜設置在具有較大墊塊反力的地方;
(5) the rubber pad should be set in a place with large counterforce.
(6)在同一橋墩上的幾個橡膠墊塊應具有相近的轉動剛度;
(6) several rubber padding blocks on the same pier should have similar rotational stiffness.
總之，橋梁橡膠墊塊的布置原則是既要便于傳遞支座反力，又要使橡膠墊塊能充分適應梁體的自由變形。
In a word, the arrangement principle of bridge rubber pad is not only to transfer the support back force, but also to make the rubber pad fully adapt to the free deformation of the beam.

橡膠墊塊的安裝
The installation of rubber pad
(1)在墊塊安裝之前應對支座的安裝位置進行測量檢驗，支座安裝平面應和支座的滑動平面或滾動平面平行，其平行度的偏差不宜超過2‰。
(1) the installation location of the bearing should be measured and checked before installing the cushion block. The bearing installation plane should be parallel to the sliding plane or rolling plane of the bearing, and the deviation of parallelism should not exceed 2 per thousand.
(2)墊塊安裝前應對活動支座頂、底板的相對位置進行檢查。
(2) before the pad is installed, the relative position of the top and floor of the movable support should be checked.
(3)墊塊安裝后，滾動和滑動平面應水平，其與理論平面的斜度不大于2‰。支座上、下板中心應對中，其偏差不大于2‰。
(3) after the block is installed, the rolling and sliding plane should be horizontal, and the slope of the plane is not more than 2 per thousand with the theoretical plane. The deviation of the upper and lower plate centers is not more than 2 per thousand.
(4)為保證墊塊安裝平整，一般應在支座底面與職稱墊石頂面之間，搗筑20~50mm厚的干硬性無收縮砂漿墊層。
(4) in order to ensure the smooth installation of the pad, the dry and hard shrinkage mortar cushion of 20~50mm thick should be rammed between the bottom of the support and the top of the title stone.
