According to the method for assembling the floor deck 20 of the embodiment of the invention, the floor deck 20 is formed by welding the double-truss system 10 and the steel pipe beam 21 and filling concrete into the installation space 11, so that the construction of the floor deck 20 is simpler and faster, and the construction efficiency of the floor deck 20 is improved. And the floor support plate 20 assembled and constructed on site has higher applicability, so that the market competitiveness of the floor support plate 20 is improved.
As shown in fig. 2, in some embodiments, before filling the installation space 11 with concrete, the assembly method further comprises: the detachment-free template 300 is installed on a side of the first fixing portion 110 facing the second fixing portion 120.
It is understood that the detachment-free template 300 is suitable for being disposed between the adjacent first connecting portions 210, and the detachment-free template 300 is disposed on a side of the first fixing portion 110 facing the second fixing portion 120. In this way, in the use process of the double-truss system 10, the detachment-free templates 300 are further clamped on the adjacent first fixing portions 110, and the detachment-free templates 300 can be supported between the first fixing portions 110 to seal the lower ends of the double-truss system 10, so that when the double-truss system 10 constructs the floor support plate 20, the capacity of supporting the concrete 12 and the construction load is achieved, and the economy of the floor support plate 20 is further improved. Furthermore, the non-removable form 300 is further clamped on a side of the first fixing portion 110 facing the second fixing portion 120, so that when the non-removable form 300 and the non-removable form 300 constitute the concrete 12 poured on the floor slab 20, the bearing capacity of the floor slab 20 can be improved by transmitting the bearing capacity to the first fixing portion 110. Meanwhile, the detachment-free form 300 is mounted on the first fixing portion 110 by means of bonding or riveting, and the heat-insulating and sound-insulating panel is laid on the detachment-free form. The thermal insulation and sound insulation performance of the floor bearing plate can be improved, the economic applicability of the double-truss system 10 is improved, and the production cost is reduced.
Furthermore, the non-removable form 300 and the first fixing portion 110 may be fixed by riveting with flat head screws. Compared with bonding, riveting has higher stability, so that the connection between the non-dismantling template 300 and the first fixing portion 110 is more stable and reliable, and the structural strength of the double-truss system 10 is improved. Meanwhile, compared with the bonding connection, the riveting is higher in mechanization degree, so that the labor cost can be reduced, the market competitiveness of the double-truss system 10 is improved, the connection efficiency between the detachment-free template 300 and the first fixing part 110 can be improved, and the production efficiency of the double-truss system 10 is improved. By adopting the assembly process of the non-dismantling template, a large number of construction workers for manufacturing, installing and dismantling the template can be reduced on site, the construction efficiency is further improved, and the construction progress is accelerated.
In some embodiments, a gap 700 is formed between the detachment-free mold plate 300 and the first connecting portion 210, and the gap 700 is filled with concrete. Like this, the concrete 12 can be filled to clearance 700 for the whole thickness of floor deck 20 reduces, and simultaneously, clearance 700 can also constitute the rib after installing concrete 12, and the rib has higher structural strength, thereby lets floor deck 20's structure more reliable and stable.
In some embodiments, the width of the gap 700 is greater than or equal to 30 mm. It will be appreciated that the width of the gap 700 is too small to fill sufficiently when concrete is poured. The gap filled with concrete is formed as a rib beam, which increases the bearing pressure of the first fixing portion 110, so that the structural strength of the first fixing portion 110 is improved, thereby improving the usability of the dual-truss system 10 and enhancing the structural strength of the floor deck 20. In this way, the width of the gap 700 is set to 30mm or more. Not only can let the first fixed part 110 can be better bear the concrete that fills in the clearance 700 for the rib after the concrete solidifies has higher structural strength, support double truss system 10 that can be better, make the building carrier plate structure 20 that double truss system 10 founded more reliable and stable, promote the performance of building carrier plate 20, make the market competition of building carrier plate 20 obtain promoting.
