火电厂的主厂房各层楼板结构施工中，设计上多采用压型钢板砼梁板结构的形式，此结构形式为了加强钢梁与楼板的整体性，钢梁上均设计锚筋或剪力钉以加强梁板的整体性。为了满足设计要求，传统施工工艺采用了两种形式实现的：一是在钢梁上现场焊接“U”型锚筋；二是在钢梁上采用熔焊技术焊接剪力钉。

Construction of the main building for thermal power plant of every floor structure, design the profiled steel concrete beam slab structure, this structure in order to strengthen the integrity of steel beam and slab, steel anchor bar or shear studs are designed to strengthen the overall beam plate. In order to meet the design requirements, the traditional construction process is implemented in two forms: one is to weld the "U" anchor bar on the steel beam; the other is to use the welding technology to weld the shear studs on the steel beam; two.

第一种施工工艺费工费时，已基本被淘汰；第二种施工工艺属机械自动焊，大大得高了工作效率，施工成本也相对降低，已为部分工程项目施工所采用。

The first construction process is time-consuming, has basically been eliminated; second kinds of construction technology of mechanical automatic welding, high work efficiency greatly, the construction cost is relatively lower, has been part of the construction project.

目前，剪力钉固定出现了非焊接技术，即喜利得剪力钉固定技术，莱城电厂＃3、＃4机主厂房各层楼板结构压型钢板砼中压型钢板固定采用了喜利得剪力钉技术。主厂房各层楼板结构压型钢板砼中压型钢板固定采用了喜利得剪力钉技术，其优点如下：

At present, the emergence of non fixed shear stud welding technology, namely the Hilti shear nails fixed, the main plant in Laicheng Power Plant 3, 4 machine each floor structure of profiled steel concrete profiled plate fixation with Hilti shear stud technology. The main building of every floor structure of profiled steel concrete profiled plate fixation with Hilti shear stud technology, its advantages are as follows:

a操作简单，非特殊工种即可完成，传统施工工艺及机械自动焊，操作均须合格焊工才能胜任。工种为普通壮工一个可独立操作，单位人工费低，12.53元/工日，机械自动焊每台班两个工日，人工费焊工24.22元＊2=48.44元必须/工日。

A operation is simple, non special type of work can be completed, the traditional construction process and mechanical automatic welding, operation must be qualified welder to be competent. As a type of ordinary laborers can operate independently, unit labor costs low, 12.53 yuan / day, mechanical automatic welding for each class is two days, labor costs 24.22 yuan 2=48.44 yuan to the welder * / day.

b力钉采用专用枪，无需另配力能。设备易操作与携带，无须施工准备。自动机械焊每班必须进行机械定位、电源接线等施工准备，必须具有电源力能配置。

The B force nail uses a special gun without additional force. The equipment is easy to operate and carry, without construction preparation. Automatic mechanical welding, each class must be mechanical positioning, power wiring and other construction preparation, must have power, power, configuration.

c 利得剪力钉工作效率高，500个/工日；机械自动焊200个/台班。剪力钉采用冲击力，利用专用锚钉使剪力钉与钢梁连接，不会对压型钢板与钢梁防腐产生灼伤；机械自动焊对压型钢板与钢梁产生灼伤，防腐被破坏，必须进行修补。

C gains the shear studs high work efficiency, 500 / day; 200 / number of automatic welding machine. The impact force of shear studs, using special anchors to shear nails and steel beam connection, not on the pressure plate and steel corrosion produced burns; mechanical automatic welding of profiled steel sheet and steel beam burns, corrosion damage, must be repaired.

d喜利得剪力钉设备一次投入小，一台自动焊机造价可购置8把剪力钉专用枪，同样的工作能力，自动机械焊投入为剪力钉专用枪的20

D Hilti shear pin device into a small, an automatic welding machine cost can purchase 8 shear studs special gun, the same work capacity, automatic welding input to shear nails special gun 20

倍。在喜利得剪力钉技术应用前，对施工人员进行了培训，培训内容为剪力钉专用枪的使用与保养。

Times. In the application of Hilti shear nails before construction of personnel training, the training content for the use and maintenance of the shear nails special gun.
