火電廠的主廠房各層樓板結構施工中,設計上多采用壓型鋼板砼梁板結構的形式,此結構形式為了加強鋼梁與樓板的整體性,鋼梁上均設計錨筋或剪力釘以加強梁板的整體性。為了滿足設計要求,傳統施工工藝采用了兩種形式實現的:一是在鋼梁上現場焊接“U”型錨筋;二是在鋼梁上采用熔焊技術焊接剪力釘。

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.

第一種施工工藝費工費時,已基本被淘汰;第二種施工工藝屬機械自動焊,大大得高了工作效率,施工成本也相對降低,已為部分工程項目施工所采用。

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,剪力釘固定出現了非焊接技術,即喜利得剪力釘固定技術,萊城電廠#3、#4機主廠房各層樓板結構壓型鋼板砼中壓型鋼板固定采用了喜利得剪力釘技術。主廠房各層樓板結構壓型鋼板砼中壓型鋼板固定采用了喜利得剪力釘技術,其優點如下:

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操作簡單,非特殊工種即可完成,傳統施工工藝及機械自動焊,操作均須合格焊工才能勝任。工種為普通壯工一個可獨立操作,單位人工費低,12.53元/工日,機械自動焊每臺班兩個工日,人工費焊工24.22元*2=48.44元必須/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力釘采用專用槍,無需另配力能。設備易操作與攜帶,無須施工準備。自動機械焊每班必須進行機械定位、電源接線等施工準備,必須具有電源力能配置。

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 利得剪力釘工作效率高,500個/工日;機械自動焊200個/臺班。剪力釘采用沖擊力,利用專用錨釘使剪力釘與鋼梁連接,不會對壓型鋼板與鋼梁防腐產生灼傷;機械自動焊對壓型鋼板與鋼梁產生灼傷,防腐被破壞,必須進行修補。

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喜利得剪力釘設備一次投入小,一臺自動焊機造價可購置8把剪力釘專用槍,同樣的工作能力,自動機械焊投入為剪力釘專用槍的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。在喜利得剪力釘技術應用前,對施工人員進行了培訓,培訓內容為剪力釘專用槍的使用與保養。

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.
