D80 type bridge expansion joint

行業(yè)D80伸縮縫是單組式模數伸縮縫：GQF-C型、GQF-Z型、GQF-L型、GQF-F型、GQF-E

Industry D80 expansion joint is a single group of modulus expansion joints GQF-C， GQF-Z， GQF-L， GQF-F， GQF-E

型的統稱。全都是采用熱軋整體成型的異型鋼材設計的橋梁伸縮縫產品，適用于伸縮量

The general name of the type. All of the bridge expansion joints designed by hot rolled monolithic steel， suitable for expansion

80mm以下的的橋梁接縫。

The bridge joints below 80mm.

D80型橋梁伸縮縫代號

D80 type bridge expansion joint code

橋梁伸縮縫代號表示方法與中華人民共和國交通行業(yè)標準表示方法相一致.以

The representation method of bridge expansion joint is in accordance with the standard representation method of Peoples Republic of China transportation industry. GQF-C60，

GQF-F80、GQF-C60（NR）、GQF-F80（CR）型橋梁伸縮縫為例，其中GQF為交通行業(yè)標準

GQF-F80， GQF-C60 （NR）， GQF-F80 （CR） bridge expansion joint is an example， of which GQF is the standard of transportation industry

規(guī)定的橋梁伸縮縫裝置代號，型式代號直梁連桿鏈條型表示異型鋼材

The specified code of bridge expansion joint device， type code name straight beam connecting rod chain type （C， Z， F， E， L） to express the special-shaped steel

的形狀，數字表示伸縮裝置位移量0-80mm。

The shape and number represent the displacement of the telescopic device 0-80mm.

NR和CR表示橡膠種類NR表示天然橡膠、CR表示氯丁橡膠

NR and CR represent the types of rubber NR indicates that natural rubber and CR represent chloroprene rubber

橋梁伸縮縫所用膠料適用范圍

The scope of application of rubber for bridge expansion joint

1、采用氯丁橡膠（CR）的伸縮縫裝置適用于溫度為-25+60地區(qū)

1. The expansion joint device with chloroprene rubber （CR） is suitable for the temperature of -25 +60 area

2、采用天然橡膠（NR）的伸縮縫裝置適用于溫度為-40+60地區(qū)

2， the use of natural rubber （NR） device is suitable for temperature -40+60 area expansion joint

橋梁設計單位在選擇了D80型橋梁伸縮縫產品后，應提供以下資料

The bridge design unit should provide the following information after selecting the D80 type bridge expansion joint product

1、 橋梁的橫斷面圖（包括橫坡、人行道、安全帶、欄桿的位置及尺寸）.

1. The cross section diagram of the bridge （including the position and size of the cross slope， the sidewalk， the seat belt， the railing）.

2、橋梁伸縮縫的施工實施時間及安裝時溫度的變化幅度。

2. The construction time of bridge expansion joint and the change range of temperature during installation.

3、用戶有特殊要求應明確注明。

3， the special requirements of the user should be clearly stated.

（注：如用戶不提供定位值，則生產公司一律按產品的額定大伸縮量一半定位出廠）

（Note if the user does not provide the positioning value， the production company is located at half of the rated maximum scale of the product.）

1、橋梁伸縮縫按設計要求全部組裝好后，由生產廠家或用戶運往施工現場。如其長度超過

1. When the bridge expansion joints are all assembled according to the design requirements， the manufacturers or users are transported to the construction site. As long as its length exceeds

運輸允許限度或由于其他原因不能整體運輸時，可以采用拆分的方法運輸。

Transportation may be carried out by means of separation when transportation is permitted or cannot be transported as a whole for other reasons.

2、橋梁伸縮縫運抵施工現場后，其存放地點應盡量接近安裝位置，并放置在少高于地面

2. After the bridge expansion joint is shipped to the construction site， the location of the storage site should be as close as possible to the installation position， and should be placed at least above the ground.

30cm的支撐物上。

On the support of 30cm.

3、同樣優(yōu)良的橋梁伸縮縫，不同的安裝質量，使用效果和耐久性會有明顯差別。

3， the same excellent bridge expansion joint， different installation quality， the use effect and durability will have obvious difference.
