由于钢筋桁架楼承板可以显著减少现场钢筋绑扎工程量,加快施工进度,增加施工安全保证,在厂房及民用住房建筑中有着非常广泛的应用。为保证施工安全,我们需按照以下顺序和方法正确施工,下面
济南楼承板厂家为您进行讲解。
As the steel bar truss floor support plate can significantly reduce the amount of reinforcement binding work on site, speed up the construction progress, and increase the construction safety assurance, it has a very wide application in factory buildings and civil housing buildings. In order to ensure the construction safety, we need to carry out the construction correctly according to the following sequence and methods. Next, Jinan floor bearing plate manufacturer will explain to you.
(1)施工顺序
(1) Construction sequence
A.平面施工顺序:每层钢筋桁架楼承板的铺设宜根据施工图起始位置向一个方向铺设,后处理边角部分;
A. Plane construction sequence: the reinforcement truss floor support plate of each floor should be laid in one direction according to the starting position of the construction drawing, and then the corners should be treated;
B.立面施工顺序:随主体结构安装施工顺序铺设相应各层的钢筋桁架楼承板。
B. Facade construction sequence: along with the main structure installation and construction sequence, the reinforcement truss floor support plates of each floor shall be laid.
(2)钢筋桁架楼承板安装适宜在下一节钢柱及配套钢梁安装完毕后进行。
(2) The installation of the steel truss floor bearing plate is suitable for the installation of the next steel column and supporting steel beam.
(3)楼板铺设前,应按图纸所示的起始位置放设铺板时的基准线。对准基准线,安装块板,并依次安装其它板。楼板连接采用扣合方式,板与板之间的拉钩连接应紧密,保证浇筑混凝土时不漏浆。
(3) Before laying the floor slab, the reference line for laying the slab shall be set according to the starting position shown in the drawing. Align the reference line, install the first plate, and install the other plates in turn. The connection of the floor slab adopts the buckle method, and the hook connection between the slab and the slab shall be tight to ensure that there is no mortar leakage during concrete pouring.
(4)钢筋桁架楼承板就位之后,应将其端部的竖向钢筋及底模与钢梁点焊牢固。沿板宽度方向将底模与钢梁点焊,焊接采用手工电弧焊,间距不大于300mm。
(4) After the reinforcement truss floor bearing plate is in place, the vertical reinforcement at its end and the bottom formwork shall be firmly welded with the steel beam. Spot weld the bottom formwork and the steel beam along the width direction of the plate. Manual arc welding is used for welding, and the spacing is not more than 300mm.
(5)待铺设一定面积之后,必须及时绑扎板底钢筋,以防止钢筋桁架侧向失稳。同时必须及时按照设计要求设临时支撑,并确保支撑稳定、可靠。
(5) After laying a certain area, the reinforcement at the bottom of the slab must be bound in time to prevent the lateral instability of the reinforcement truss. At the same time, temporary support must be set up in time according to the design requirements, and the support must be stable and reliable.
(6)板端及板边与梁重叠处,不得有缝隙。
(6) There shall be no gap at the overlap of plate end and plate edge and beam.
(7)附加钢筋工程及管线敷设。
(7) Additional reinforcement works and pipeline laying.
A.待铺设一定面积后,应按设计要求设置楼板支座连接筋、加强筋及负筋等。
A. After laying a certain area, the floor support connecting bar, reinforcing bar and negative bar shall be set according to the design requirements.
B.楼板开孔处,应按设计要求设洞口边加强筋,四周设边模板,待楼板混凝土达到设计强度后,方可切断钢筋桁架楼承板的钢筋及底模。
B. At the opening of the floor slab, the reinforcing bar at the opening shall be set according to the design requirements, and the side formwork shall be set around. After the floor slab concrete reaches the design strength, the reinforcement and bottom formwork of the reinforced truss floor support plate can be cut off.
C.板中敷设管线,正穿时采用刚性管线,斜穿时宜采用柔韧性较好的材料。
C. When laying pipelines in the board, rigid pipelines shall be used when crossing directly, and materials with good flexibility shall be used when crossing obliquely.
(8)栓钉焊接
(8) Stud welding
钢筋桁架楼承板底模与母材的间隙应控制在1.0mm以内,以保证良好的栓钉焊接质量。
The clearance between the bottom formwork of the steel bar truss floor support plate and the base metal shall be controlled within 1.0mm to ensure good stud welding quality.
(9)边模板安装
(9) Installation of side formwork
安装时,将边摸板紧贴钢梁面,边摸板与钢梁表面每隔300mm间距点焊长25mm、高2mm的焊缝。安装后,要全面检查,确保所有的边模都已经按照施工图要求安装完毕,保证无漏浆部位的存在。
During installation, the edge template shall be closely attached to the steel beam surface, and the weld with length of 25mm and height of 2mm shall be spot welded with the steel beam surface every 300mm. After installation, it is necessary to conduct a comprehensive inspection to ensure that all the side forms have been installed according to the requirements of the construction drawings, and that there is no leakage.
