1.&产品简介Introduction
&&&&锻制圆头吊钉，符合各国制定的用于预制混凝土组件的吊钉系统及有关的吊运安全条例，是保证混凝土预制件在生产和运输过程安全的重要保障。圆形吊钉具有生产使用方便，工人操作时间最短的优势。&
&&&Spherical head anchors, meet the requirements of the European machine guideline (MD) 2006/42/EC. The required steel load capacity for transport systems is defined in these guidelines.&Which is to ensure that the concrete precast in the production and transportation process an important guarantee of security. Easy&to use&and the shortest operating time.
1.1 工作原理&Working principle&
&&&&圆头吊钉通过圆脚把载荷转移到混凝土，从而用相对较短的吊钉也能获得较高的允许载荷。即使用在薄墙中，载荷也能有效传递到混凝土与钢筋上。由于吊钉的圆脚轴对称形状，不象其它类型的预埋吊钉/螺栓，因此放置吊钉时不需要有特殊的定位。
理论上说，愈长的吊钉因为可以建立较大的混凝土载荷圆锥体，因此也能承受较大载荷。吊钉应用中的失效分析就是根据此载荷圆锥体的强度作出的。
&&&&Spherical head anchor&transfers the load to the concrete through the rounded foot, thus can obtain the higher allowable load with the relatively short suspender. Even in the thin wall, the load can be effectively transmitted to the concrete and steel. Because of the symmetrical shape of the spikes, unlike other types of prefabricated hanging nails / bolts, no special positioning is required when placing the spherical head anchor.
&&&In theory, the longer the anchor&can build a larger concrete load cone, and therefore can withstand the greater load. The failure analysis of hanging nails is based on the strength of the load cone.
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&the fracture surface&when&the load is too large
1.2&安全系数&Safety factor
&&&&圆头吊钉的材料安全系数为3，混凝土失效安全系数为2.5。万向接头（专用吊具）的材料安全系数为5.0。
&&&&The safety factor of the anchor material is 3.0,&and the failure safety factor of concrete is 2.5.
&&&&Universal joint (lifting shackle) material safety factor is 4.0.
1.3&应用安全 Application security&&&
&&&为了达到满足1.2对安全的要求、设计，施工与吊运要注意以下方面：
a. 禁止对圆头吊钉进行改变和焊接，禁止将吊钉拆出重复使用。
b. 请严格按照&砼的&圆头吊钉的安装和使用说明（本手册）使用，严禁与其它厂家的系统部件混合应用。
c. 混凝土预制件设计时请参照本说明或样本进行计算与设计，如需要本说明以外的数据，请联系我们。
d. 同时要确认能满足现行的的建筑规范、规程与标准。
e. 因吊运时，受力点会使预制件内应力分布改变，应根据设计的吊运状态进行受力计算，并考虑是否需要加固预制件，以免产品受损。(此方面请参考预制构件的相关规范）
&&&In order to meet the safety requirements of 1.2, design, construction and lifting&as the following:
a. Prohibit the round head anchor&to change and welding, prohibit the head anchors or re-
b. Please strictly follow the &TonDe& head anchor&installation and introduction&(this manual) to use, prohibited to mixed use&with other manufacturers
c. Please refer to this instruction or samples&for calculation and design of concrete precast&parts. Please contact us if you need more&&
d. While ensuring&to meet&the existing building codes, proc
e. The stress distribution in the precast&part will be changed by the force point when lifting. The force calculation should be carried out according to the designed lifting state, and the need to reinforce the precast&parts&to avoid damage to the product. (Refer to the relevant specifications of precast&components).
&2.&吊钉系统的选用要点&Key Points of Head anchor&System
&&&&下列是对圆头吊钉的选型与其中要考虑的应用条件的说明，请仔细阅读。
&&&&The following is a description of the selection of the round head anchor&and the application conditions to be considered, kindly&read.&
2.1&圆头吊钉载荷的影响因素 &Influencing Factors of Load of Head Anchor
&&&&&吊钉的正确选择应根据作用于吊钉的载荷，依据以下因素而定（在计算时必须考虑到这些因素）：
n 预制件的重量 ■ 吊钉的数量与位置
n 用吊链时产生的展开角度 ■ 吊链/吊钉的对角提拉特性
n 动态力 ■ 对模板的粘附力
&&&&The&choice of head anchor should be based on the load, according to the following factors.&
n The weight of the precast concrete product&■ The quantity and position of the head anchors&
n &Expansion&angle&&&■ Diagonal pull characteristics&of chains / head anchors
n Dynamic force ■ Adhesion to the template
2.2&&混凝土预制件的重量 The weight of the precast concrete product
a. 正常情况下，可按24kN/m3的比重计算新制钢筋混凝土预制件的重量。
b. 如果是高密度钢筋混凝土预制件，按25kN/m3的比重算出的重量再加钢筋重量的70%即为预制件的重量。
a.Normally, to calculate the weight of reinforced concrete according to the specific gravity of 24KN/m3.
b. If high-density precast concrete products,&the weight calculated by the specific gravity&of 25 KN/m3 plus 70% of the weight of the reinforcing bar is the weight of the precast concrete products.
2.3&吊钉的数量与定位 &The quantity and position of the head anchor&
&&&&吊链数量由所用的吊钉数量决定，如果多于3个吊点有可能产生静力不确定，因此需要适当的方法(例如：用分配梁、滑轮等) 确保所有支链的承重都相等。
&&&&在任何可能的情况下，应用多于1颗吊钉，吊钉应定位在使它们之间的连线与预制件重心相交的位置上。如果因为特殊原因不能遵循这个原则，那么根据吊钉与重心的距离，侧拉力会增加而且会作用于各个吊钉上。
我们必须确定这些力的大小以便选择正确的吊钉，必要时请提供图纸，并咨询我公司技术工程师。
&&&&The number of hanging chains is determined by the number of lifting anchor&used. If more than 3 lifting points are likely to generate static uncertainty, appropriate methods (e.g, distribution beams, pulleys, etc.) are required to ensure that all branches are equal in weight.&
Wherever possible, more than one lifting anchor&shall be applied and the lifting anchor&shall be positioned in such a way that the line between them is intersected with the center of gravity of the preform. If this principle can not be followed for special reasons, depending on the distance between the stud and the center of gravity, the side tension will increase and will act on each anchor.
We must determine the size of these forces in order to choose&the right head anchors, if necessary, please provide drawings and consult&with our technical engineers.
&2.4&拉力（载荷）方向&Tension (load) direction
&&&&&拉力方向主要有3种：
&&&&轴向拉力（axial tension）：即沿着吊钉的轴线受拉力
&&&&斜向拉力（diagonal tension）：即轴向拉力产生倾斜，在吊钉圆头部产生此种应力。一般在设计时需要考虑加固，以抵消产生的侧力。
侧向拉力（lateral tension）：可能因为需要满足预制件的吊运需求，吊钉设计时安排要承受侧向拉力。此种情况，加固与吊运安全是需要很小心处理的。
&&&&Three main directions of tension&as below：&
&&&&axial tension：tension along the ax&
&&&&diagonal tension：axial tension produced tilt, such stress in the head anchor&round&part. Generally need to be considered in the design of reinforcement,&to offset the side force generated.
lateral tension&: &for&the lifting needs of precast concrete&parts, head anchor&designed to withstand the lateral tension. In this case, reinforcement and lifting safety&need to be very careful handling.
&2.5&静力系统 &Static system
&A)静力不确定系统
&&&&若采用静力不确定的吊链，必须以2个吊钉来计算所能承受所有的载荷。
A)Static Uncertainty System
&&&&If use the static uncertain chains, must calculate&whether&two&head anchors&can bear all the load.
B)静力确定系统
&&&&若采用活动分配梁和对称的吊链，则4个吊钉承受的相等载荷。补偿吊环可在任何时候保证载荷分配相等。
B) Static force determination system
&&&&If the activities of the distribution beam and symmetrical hanging chain, the four head anchors bear the same load. The compensation&rings could&ensure that the load distribution is equal at all times.
&&&&&&&&&&&&&&&&&&&&&&Activity distribution beam &&&&&&&&&&&&Compensation rings
滑轮的使用也能确保吊链支链和吊钉的载荷相等。(如: 吊立系统Tilt-up System)
The use of pulleys also ensure that the loads of the chain link and suspension&of head anchor&are&equal.&(e.g Tilt-up System)
&&&&&&&&&&&&&&&&&&&&&&&&&&
2.6&展开角度&Expansion&Angle
如果吊链在使用时形成一个力三角，那么对比较简单的垂直提拉来说，作用于吊钉(吊链载荷)的力就增加了，展开角增大，作用于吊钉的力就增加，在选择吊装吊钉时，这一因素根据展开角度&由系数&修正。我们建议扩张角为60o，应避免90o以上的张角，严禁120o以上的张角。
If the chain is in use to form a force triangle, then for the relatively simple vertical pulling, the force acting on the head anchor&(sling load) increases, the expansion angle increases, the force acting on the head anchor increases , this factor is corrected by the coefficient&&&in&accordance with the development angle&&.&When the head anchor &is selected. We recommend that the expansion angle of 60o, should avoid more than 90o&angle, is strictly prohibited more than 120o&angle.
2.7&动态力 &Dynamic force&&&
&&&&动态力大小主要取决于起重机与载荷传递机构之间的联结。
&&&&钢丝绳或合成纤维缆绳具有减振效应，这种减振效应随缆绳长度的增加而增加。相反，缆绳长度较短则不利于减振。
&&&&在不利于减振的条件下，作用于吊钉的力必须根据下表(考虑到冲击系数&P)核算出来。
&&&&The magnitude of the dynamic force depends primarily on the connection between the crane and the load transfer mechanism.&
&&&&The wire rope or synthetic fiber cable has a vibration-damping effect, which increases as the length of the cable increases. On the contrary, short cable length is not conducive to vibration.
&&&The force acting on the head anchor&must be calculated according to the following table ( the impact coefficient &) under conditions that are not conducive to vibration damping.&
2.8&模板的吸附阻力&Adsorption resistance of the template
&&&&当预制件第一次从模板里提拉出来时，所需要的拉力是实质混凝土重量的数倍。 这是由于模板的吸力和粘附力或模板的摩擦力所产生的。在模板上使用合适的脱模剂可减少这些影响。(现代营造的研究结论：真空压力可能才是主要因素)
所有这些因素中，模板的粘附力由模板表面的类型决定（或参考相关规范规定）：
When the preform is pulled out of the template at&the first time, the required tension is several times the actual concrete weight. This is due to the suction and adhesion of the template or the friction of the template. These effects can be reduced by the use of a suitable release agent on the template. (Modern construction of the study concluded: vacuum pressure may be the main factor).
All these factors, the adhesion of the template is determined by the type of template surface (or reference to the relevant specification):&
对&板（双T板）和槽型板吸附力必须考虑下表所列系数，除非用特殊方法脱模。
For the & plate (double T plate) and the slot plate adsorption force as below, unless special methods are used for stripping.
2.9&吊钉的拉力 Pulling force of head anchor
&&&&作用于吊钉的拉力Z通常是由以下方程序决定的。
&&&&从模板提拉： Z = G x & x &/n
&&&&或为 Z =（G + ha x A）& /n
&&&&吊运时拉力则为 Z = G x & x &P /n &&其中的代号定义如下：
&&&&Z = 作用于吊钉的拉力(t) &&G = 预制物件重量(t)&&&ha = 粘附力 (kN/m2)
&&&&A = 基面面积 (m2) &&&&&&&n = 承重吊钉的数量 &&& = 张角系数
&&&&&P = 冲击系数 &&&&&&&&&&&& = 粘附系数
&&&&The force Z applied to the head anchors&is usually determined by the following procedure.&
&&&&Pull from the template： Z = G x & x &/n
&&&&or&Z =（G + ha x A）& /n
&&&&The force when lifting:&Z = G x & x &P /n &&
&&&&Z = The role of the head anchor&tension(t) &&G = the weight of precast concrete part(t)&&&ha =&Adhesion&(KN/m2)
&&&&A = base surface area&(m2) &&&&&&&n = The number of load - bearing head anchors&&&&&=&Angle factor
&&&&&P = Impact coefficient&&&&&&&&&&&&& =&Adhesion coefficient
2.10&斜向提拉 Diagonal&pulling&
&圆头吊钉和半球形凹座一起被放置在混凝土中，这样在对角提拉的过程中可通过万向连接头将水平方向的力直接传入混凝土中。
The round head anchor&is placed in the concrete together with the&recess&former&so that the horizontal force can be directly transferred into the concrete through the universal joint during diagonal pulling.
3.&圆头吊钉&Spherical head anchor
&&圆头吊钉是由承重等级为1.3 - 32 t的各种高强度棒材(如碳钢、不锈钢等)精锻而成。根据不同的用途，可以制作出不同长度的吊钉，较长的吊钉可用于边际间距小或强度低的混凝土的吊运上。
Spherical head anchors&are made of precision forging of various high strength bars (such as carbon steel, stainless steel, etc.) With load - bearing grade of 1.3 - 32 t.&According to different purposes, can produce different lengths of head anchors, longer head anchors&can be used for marginal spacing of small or low strength concrete lifting.
3.1标识符号 &Identification symbol
&&圆头吊钉和吊装设计都有明确的标识。通过标识可以对产品型号很快做出了解，避免错用产品，例如：
Spherical&head anchor and lifting design has a clear logo. Through the logo can quickly understand the product model to avoid misuse of the product.
&&表示最大起吊重量为2.5吨，标识在钉头部位
&Means the maximum lifting capacity of 2.5 tons, identified in the round&head position.
3.2&防锈保护 &Rust protection&
&&&&一般吊钉使用前后都会暴露在环境中，因此需处理好防锈问题。吊钉使用后会永远留在预制件里，假如吊钉会暴露在外，需要及时用砂浆覆盖好表面，覆盖规格要视乎建造规范。
也可以使用不同材料与工艺的吊钉来应对防锈问题，详见下表。&
&&&&Generally head anchors&will be exposed before and after use in the environment, so need to rust. Head anchors will always remain in the precast concrete parts&after use, if the head anchors&will be exposed, need to cover the surface with mortar&in time,&depends on the construction specifications.
&&&&&Also use different materials and surface treatment to deal with rust problems, as below.&
3.3&安装与使用 Installation and usage&
&&&&&圆头吊钉通过半圆凹型套头（俗称&胶波&或&半球胶套&）放置在模具中，凹型套头起固定吊钉作用并于预制件成型后形成一个用于连接万向接头（俗称&起重接驳器&、&起重离合器&）的凹面。因此不同载荷级别的部件因为设计尺寸不一样，不可能相互替换。
&&&&另一优点为万向接头在斜吊时以混凝土为支撑把水平方向的载荷直接传入混凝土中。因此，作用于大而薄的对象时不必象使用管套吊装钉那样对承载能力进行换算，不需要另外加固。
&&&&如斜吊窄长预制件，附加钢筋必须放置在薄墙对象中以调整可能出现的横向提拉力。有关细节在章节3.5.2 中给出。
&&&&The head anchor through the recess former&placed in the mold, the role of the hanging set of&anchors&and after the preform forming a universal joint for the connection (commonly known as & Lifting adapter &,&& lifting clutch &). Therefore, components of different load levels because the design size is not the same, it is impossible to replace each other.&
&&&&Another advantage is that the&universal ring&is supported by the concrete in the direction of the horizontal load directly into the concrete. Therefore, when acting on large and thin objects, it is not necessary to convert the load carrying capacity as in the use of a pipe stringer, no additional reinforcement is required.
If slanting a long preform, additional reinforcement must be placed in the thin wall object to adjust the possible lateral pulling force.&Details as 3.5.2&
&&&&墙板类预制件进行平放浇注成型后，需要进行吊立成直立状态，以方便放置。此种吊立，需要组件辅助以防止构件翻身时发生损坏和坠落事故，我们建议最好使用预制构件翻身机将墙板垂直放置，降低损坏风险。
&&&&Precast concrete panel is required to be erected in a horizontal position, in order to avoid damage and fall accidents when the components are overturned, it is recommended to use a precast turn-over machine&to place the panels vertically to&reduce the risk of damage .&
&&&&&&&&&&&&&&
&&&&&&&&&&&&&&&&&&&&&&&
3.4&圆头吊钉尺寸与边距 &Spherical head anchor&size and margin
&&&&请严格按照&表1&给出的最小边距放置吊钉，也可通过其它有效的建筑方法去减少边距(如额外加固钢筋)，详情请向我公司技术人员查询。
&砼的&圆头吊钉离预制混凝土件一边的最小距离（ar） 是吊钉长度（L）再加上钉到水泥面值&s&的3倍，即ar=3*(L+s)。
&&&&Please strictly follow the minimum margins given in Table 1, or use other effective building methods to reduce the margin (such as additional reinforcing steel bars). For details, please contact our technical staff.
&&&&The minimum distance from the side of precast&concrete&product（ar）is&3 times&of&the head anchor&length&( L )&plus anchor&to the cement face value &s&.&ar=3*(L+s)
&&&&&&&&&&&&&&&&&&&&&&
&&&&&&&&&&&&&&&
3.5&圆头吊钉的载荷与钢筋加固表 &Load and reinforcement of spherical head&anchor
&&&&&圆头吊钉的应用根据混凝土预制件的形状，可分为窄长应用和扁平的应用，按受力方向分为垂直上拉和斜向提拉 (以45度为定为定依据，方便说明情况）。
&&&&窄长扁平应用一般为墙板，承重梁等等。扁平应用一般则有楼板，管筒等等。窄长轴向应用应参照表2和表3标示的允许载荷。窄长斜拉应用应参照表4、表5标示的允许载荷。扁平应用参照表6标示的允许载荷。
&&&&Application of spherical&head anchor&according to the shape of precast&concrete parts can be divided into narrow and long flat applications,&&the force direction is divided into vertical pull and diagonal pull (&45 degrees as the basis&).
&&&&Narrow long flat applications are generally use on wall panels, bearing beams and so on. Flat applications are generally use on floor, tube and so on. For narrow and long axial applications, the allowable loads shown in Tables 2 and 3.&For long and narrow diagonal pulling&applications, the allowable loads shown in Table 4 and Table 5. For flat applications refer to the allowable loads shown in Table 6.
