鋼箱梁爬梯色彩的應(yīng)用不管是鋼爬梯還是垂直鋼爬梯，尤其是在帶有疏散性質(zhì)的鋼爬梯色彩遠(yuǎn)擇上如均為同色，從使用安全上來(lái)說(shuō)，這種設(shè)計(jì)不符合人的視覺(jué)特性，不便于人區(qū)分每一個(gè)梯級(jí)，易使人在下樓梯時(shí)產(chǎn)生一步踏多級(jí)而出現(xiàn)踏空，這在晚上或者光照度較弱時(shí)，更加凸顯一色設(shè)計(jì)在安全方面的不足。在設(shè)計(jì)斜梯級(jí)間相互區(qū)分開(kāi)，可以采取在踏面邊緣使用與其他部分不同顏色的防滑條來(lái)實(shí)現(xiàn)，但在顏色選取時(shí)應(yīng)注意： </p> <p> （1）選用顏色的對(duì)比感要適中，即在光照較弱的情況下也能較易辨別； </p> <p> （2）不同顏色的過(guò)度要平緩，這樣可以遙免眼睛須繁調(diào)節(jié)造成視覺(jué)疲勞，導(dǎo)致觀察和判斷的失誤。 </p><p style="text-indent:25px">板式橡膠支座的適用范圍：普通板式橡膠支座適用于跨度小于30m、位移量較小的橋梁.不同的平面形狀適用于不同的橋跨結(jié)構(gòu),正交橋梁用矩形支座;曲線橋、斜交橋及圓柱墩橋用圓形支座。支座安裝注意事項(xiàng)：應(yīng)盡量選擇年平均氣溫時(shí)進(jìn)行，同時(shí)必須按照設(shè)計(jì)圖紙標(biāo)明的支座中心位置正確就位，并保證支座與上、下部結(jié)構(gòu)之間緊密接觸，不得出現(xiàn)空隙。支座應(yīng)盡量水平安裝，當(dāng)必須傾斜安裝時(shí)，縱坡不能超過(guò)2%，且在選擇支座時(shí)，要考慮因傾斜安裝所需要增加的剪切變形影響，當(dāng)縱坡大于2%時(shí)，要采取措施使支座平置。箱形梁和箱形柱配合使用，能夠使得建筑物既獲得大空間，又能滿足結(jié)構(gòu)安全要求。</p><div
