鋼筋桁架樓承板是屬于無支撐壓型組合樓承板的一種；鋼筋桁架在后臺加工場定型加工，現場施工需要先將壓型板使用栓釘固定在鋼梁上，再放置鋼筋桁架進行綁扎，驗收后澆筑混凝土。那么鋼筋桁架樓承板施工方法如何？濟南彩鋼板廠為您解說：

Steel truss floor support plate is a type of unsupported compression type composite floor support plate; The steel bar truss is shaped and processed in the backend processing plant. On site construction requires the compression plate to be fixed to the steel beam using bolts, and then the steel bar truss is placed for binding. After acceptance, concrete is poured. So what is the construction method for the steel bar truss floor support plate? Jinan Color Steel Plate Factory explains to you:

1.鋼筋桁架樓承板平面及立面施工順序：每層鋼筋桁架模板的鋪設宜從起始位置向一個方向鋪設，隨主體結構安裝施工順序鋪設相應各層的鋼筋桁架模板。

1. Construction sequence of steel bar truss floor support plate plane and facade: The laying of steel bar truss templates for each layer should be from the starting position to one direction, and the corresponding steel bar truss templates for each layer should be laid along with the installation and construction sequence of the main structure.

2.樓承板鋪設前，應按圖紙所示的起始位置放設鋪設時的基準線。對準基準線，安裝塊板，將其支座豎筋與鋼梁點焊固定。再依次安裝其它板，在鋪設過程中每鋪設一跨板要進行按圖標注尺寸校對，若有偏差要隨即調整。

Before laying the floor support plate, the reference line for laying should be set according to the starting position shown on the drawing. Align the reference line, install the first plate, and fix its support vertical reinforcement with the steel beam by spot welding. Then install other boards in sequence. During the laying process, each span board should be calibrated according to the dimensions indicated in the diagram. If there is any deviation, it should be adjusted immediately.

3.樓承板連接采用扣合方式，板與板之間的拉鉤連接應緊密，保證澆筑混凝土時不漏漿，同時注意排板方向要一致，桁架節點間距為200㎜，注意不同模板的橫向節點要對齊。

3. The connection of the floor support plate adopts a buckle method, and the hook connection between the plates should be tight to ensure no leakage during concrete pouring. At the same time, it is important to ensure that the direction of the plate arrangement is consistent, and the spacing between the truss nodes is 200 mm. It is important to align the horizontal nodes of different templates.

4.平面形狀變化處（鋼柱角部、核心筒轉角處、梁面襯墊連接板等），可將鋼筋桁架模板兩端切割，切割前應對要切割的尺寸進行放線并檢查復核?？刹捎脵C械或氧氣切割，切割時盡量選擇桁架接點的部位，但必須滿足設計搭接的要求，切割后的鋼筋桁架模板端部仍需按照原來的要求焊接水平支座鋼筋和豎向支座鋼筋，若在節點中部切斷，腹桿鋼筋也需焊接在豎向鋼筋上，就位后方可進行安裝。

4. At the changes in plane shape (such as steel column corners, core tube corners, beam surface gasket connecting plates, etc.), both ends of the steel truss template can be cut. Before cutting, the dimensions to be cut should be set out and checked and rechecked. Mechanical or oxygen cutting can be used. When cutting, it is recommended to choose the joint of the truss as much as possible, but it must meet the design overlap requirements. The end of the cut steel bar truss template still needs to be welded with horizontal and vertical support steel bars according to the original requirements. If it is cut in the middle of the node, the web bar steel bars should also be welded to the vertical steel bars, and installation can only be carried out after being in place.

5.跨間收尾處若板寬不足576mm，可將鋼筋桁架樓承板沿鋼筋桁架長度方向切割，切割后板上應有一榀或二榀鋼筋桁架，不得將鋼筋桁架切斷。

If the width of the slab at the end of the span is less than 576mm, the steel bar truss floor support plate can be cut along the length direction of the steel bar truss. After cutting, there should be one or two steel bar trusses on the slab, and the steel bar truss should not be cut.

6.鋼筋桁架平行于鋼梁端部處，底模在鋼梁上的搭接不小于30mm，沿長度方向將鍍鋅鋼板與鋼梁點焊，焊接采用手工電弧焊，間距為300mm。

6. The steel bar truss is parallel to the end of the steel beam. The overlap of the bottom formwork on the steel beam is not less than 30mm. The galvanized steel plate and the steel beam are spot welded along the length direction. Manual arc welding is used for welding with a spacing of 300mm.

7.鋼筋桁架垂直于鋼梁端部處，模板端部的豎向鋼筋在鋼梁上的搭接長度（指鋼梁的上翼緣邊緣與端部豎向支座鋼筋的距離）應≥5d（d為下部受力鋼筋直徑）,且不能小于50mm，并應保證鍍鋅底模能搭接到鋼梁之上。搭接到鋼梁上的豎向鋼筋及底模應與鋼梁點焊牢固。

7. The steel bar truss is perpendicular to the end of the steel beam, and the overlap length of the vertical steel bar at the end of the template on the steel beam (referring to the distance between the upper flange edge of the steel beam and the vertical support steel bar at the end) should be ≥ 5d (d is the diameter of the lower load-bearing steel bar), and should not be less than 50mm, and it should be ensured that the galvanized bottom mold can overlap onto the steel beam. The vertical steel bars and bottom formwork overlapped on the steel beam should be firmly spot welded with the steel beam.

8.待鋪設一定面積后，必須按設計要求設置樓板支座連接筋、加強筋及負筋等。連接筋等應與鋼筋桁架綁扎連接。并及時綁扎分布鋼筋，以防止鋼筋桁架側向失穩。

8. After laying a certain area, the floor support connecting bars, reinforcing bars, and negative bars must be installed according to the design requirements. Connecting bars, etc., should be tied and connected to the steel truss. And timely bind and distribute the steel bars to prevent lateral instability of the steel bar truss.

9.邊模板安裝時應拉線校直，調節適當后利用鋼筋一端與栓釘點焊，一端與邊模板點焊，將邊模固定，邊模板底部與鋼梁的上翼緣點焊間距300mm。

9. When installing the edge template, it should be straightened and adjusted appropriately. After adjustment, one end of the steel bar should be spot welded with a bolt, and the other end should be spot welded with the edge template to fix the edge template. The distance between the bottom of the edge template and the upper flange of the steel beam should be 300mm.

10.若設計在樓板上要開洞口，施工應預留。應按設計要求設洞口邊加強筋，四周設邊模板，待樓板混凝土達到設計強度后，方可切斷鋼筋桁架模板的鋼筋及底模。切割時宜從下往上切割，防止底模邊緣與澆注好的混凝土脫離，切割可采用機械切割或氧割進行。

10. If an opening is designed on the floor slab, it should be reserved for construction. Reinforcement bars should be installed at the edge of the opening according to the design requirements, and edge formwork should be set around it. After the concrete of the floor slab reaches the design strength, the steel bars and bottom formwork of the steel bar truss formwork can be cut off. When cutting, it is advisable to cut from bottom to top to prevent the edge of the bottom mold from separating from the poured concrete. Mechanical cutting or oxygen cutting can be used for cutting.

11.鋼筋桁架樓承板安裝好以后，禁止切斷鋼筋桁架上的任何鋼筋，若確需將鋼筋桁架裁斷，應采用相同型號的鋼筋將鋼筋桁架重新綁扎連接，并滿足設計要求的搭接長度。

11. After the installation of the steel bar truss floor support plate, it is prohibited to cut any steel bars on the steel bar truss. If it is necessary to cut the steel bar truss, the same type of steel bars should be used to tie and connect the steel bar truss again, and the overlapping length should meet the design requirements.

12.鋼筋桁架樓承板鋪設好后，應做好成品保護，避免人為的損壞，禁止堆放雜物。

After laying the steel bar truss floor support plate, finished product protection should be done to avoid human damage, and stacking of debris is prohibited.
