螺栓本體數(shù)據(jù)主要包括高強鋼絲、高強鋼絞線、高強精密軋制鋼絲等高強鋼。
Bolt body data mainly include high-strength steel wire, high-strength steel strand, high-strength precision rolled steel wire and other high-strength steel.
可在拉伸載荷下自由拉伸。當這種局部伸長被固定或“凍結”時，會在巖體或各種結構上產(chǎn)生一定的預壓應力。
It can be stretched freely under tension load. When this local elongation is permanently fixed or "frozen", a certain pre-compressive stress will occur in rock mass or various structures.
因此，錨桿體是完成對介質的張拉錨固的關鍵。
Therefore, the bolt body is the key to complete the tension anchorage of the medium.
目前我國預應力錨桿使用的主要數(shù)據(jù)為高強鋼絲和高強鋼絞線，少數(shù)工程采用細軋螺紋鋼筋。
At present, the main data used for prestressing bolts in China are high strength steel wire and high strength steel strand, and a few projects adopt fine-rolled threaded steel bar.
為了使接觸面具有足夠的摩擦力，必須提高夾緊力，提高接觸面摩擦系數(shù)。
In order to make the contact surface have enough friction, it is necessary to increase the clamping force and friction coefficient of the contact surface.
部件之間的夾緊力是通過對螺栓施加預緊力來實現(xiàn)的，因此連接部件(精軋鋼筋、螺栓等)必須采用高強鋼。
The clamping force between components is achieved by applying pre-tightening force to bolts. Therefore, high strength steel must be used to connect components (finishing steel bar, bolts, etc.).
它是由40Si2MnV或45SiMnV高強鋼制成，具有的外螺紋軋制在整個鋼筋上。
It is made of 40Si2MnV or 45SiMnV high strength steel with perfect external threads rolled on the entire steel bar.
帶有內(nèi)部精密鋼錨的連接器或錨可用于連接或錨定任意截面。采用這種錨桿體，施工方便，錨固可靠。
Connectors or anchors with internal precision steel anchors can be used to connect or anchor arbitrary sections. With this kind of bolt body, the construction is convenient and the anchorage is safe and reliable.
