In each assembly module, as shown in fig. 2, the steel joist assembly frame 1 is provided with a group of first C-shaped keels 5 arranged in parallel and a group of second C-shaped keels 6 arranged in parallel, web plates of the first C-shaped keels 5 and the second C-shaped keels 6 are vertically arranged, the first C-shaped keels 5 and the second C-shaped keels 6 are vertically connected in a plane through self-tapping screws, the steel joist assembly frame 1 encloses an outer frame into a rectangular shape, the outer contour of the assembly module is also rectangular, and the inner part of the assembly module is partitioned into rectangular spaces by the first C-shaped keels 5 and the second C-shaped keels 6. Thus, the first C-shaped keel 5 and the second C-shaped keel 6 are each parallel to the one-sided rectangular frame. The C-shaped keels are fastened and connected through screws at the mutually overlapped positions.
The connection embodiment of the steel keel assembly is that a through hole is arranged at the junction of a first C-shaped keel 5 in the middle of the steel keel assembly 1 and a second C-shaped keel 6 and is used for vertically penetrating through the second C-shaped keel 6, and the overlapping flanges at the junction of the first C-shaped keel 5 and the second C-shaped keel 6 are fastened and connected through tapping screws, see fig. 3 and 4. The two ends of the first C-shaped keel 5 are overlapped with the flanges of the second C-shaped keel 6, and the overlapped parts are fastened and connected through tapping screws. Thus, the first C-runner 5 and the second C-runner 6 are slightly different in height by twice the flange thickness. The width of the through hole is equivalent to the width of the flange of the second C-shaped keel 6, and the height of the through hole is equivalent to the height of the second C-shaped keel 6. The overlapping parts of the flanges of the first C-shaped keels 5 and the second C-shaped keels 6 are fastened and connected through self-tapping screws.

The European style board is also known as oriented strand board, also known as OSB board. It is a synthetic wood. The European pine board is a directional structural board which is manufactured by using small-diameter materials, m-cut materials and wood cores as raw materials, processing long flaking (generally 40-100mm long, 5-20 mm wide and 0.3-0.7 mm thick) by special equipment, and carrying out deoiling, drying, sizing, directional paving, hot press forming and other processes. The surface layer flaking is longitudinally arranged, and the core layer flaking is transversely arranged. The criss-cross arrangement reorganizes the wood texture structure, thoroughly eliminates the influence of the internal stress of the wood on the processing, and ensures that the wood has remarkable workability and moisture resistance. Because the OSB is internally of a directional structure, has no joint, no gap and no crack, has good overall uniformity and extremely high internal bonding strength, the OSB has super strong nail holding capacity which is incomparable with that of common plates, regardless of the center or the edge.
The plywood is made up by cutting wood segment into single boards or cutting wood Fang Bao into Cheng Baomu, and then using adhesive to glue them to form three-layer or multi-layer plate material, usually using odd-layer single boards, and making the fibre directions of adjacent layers of single boards mutually perpendicular and glue them together.
Cement fiberboard, also known as fiber cement board and fiber cement pressure board. The building material is prepared with siliceous and calcareous material as main material, plant fiber as material and through pulping, papermaking, pressurizing and maintaining.
The profiled steel sheet is hot galvanized steel sheet or color galvanized steel sheet, and is rolled and cold bent into various wave forms, and has the characteristics of light weight, high strength, beautiful appearance, durability, simple and convenient construction, earthquake resistance, fire resistance and the like. The thickness is usually 0.25 to 2.3mm.

The heat-insulating sound-insulating module 3 adopts rock wool boards or glass heat-insulating cotton. The steel joist assembly frame is cut in a factory or on site according to the joist spacing dimension framework, and the lower part of the soundproof cotton can be supported by a steel drawstring 4.

First, a C-shaped keel is manufactured for the steel keel assembly 1: a steel plate with the thickness of 0.6-3.0mm is rolled into section C-shaped steel by cold bending, and a surface is plated with zinc layers in an aluminum manner, so that the steel keel assembly frame of the standardized floor slab module is cut off according to a set length to serve as a standby C-shaped keel section. When the C-shaped keel is manufactured, the edge of the C-shaped keel is bent inwards after the C-shaped keel is formed, so that an inwards flanging is formed, and the compression strength is enhanced.
The thickness of the C-shaped keel is very thin, so that the C-shaped keel is light in weight, easy to carry and assemble and low in steel consumption.
Thereafter, a first C-shaped keel 5 is made: a through hole 8 is formed in a preset junction with the second C-shaped keel 6, the height of the through hole is the full height of the web plate, and the width of the through hole is 4-10mm larger than that of the C-shaped keel section; screw preformed holes are formed in the screw fastening positions of the second C-shaped keels 6.

And (3) manufacturing a second C-shaped keel 6: a transverse rib is pressed at least one end part, and a transverse rib is pressed at a preset junction with the first C-shaped keel 5, so that the height of a second C-shaped keel pressed at the rib is shortened by 2-6mm; a screw preformed hole is formed in the screw fastening position of the first C-shaped keel 5;
the scheme of the invention utilizes the characteristics of toughness and easy deformation of the thin steel plate to manufacture the steel keel frame: the second C-shaped keel 6 removes the flanging at the preset junction with the first C-shaped keel 5, and the width of the removed flanging is the same as the width of the through hole 8. The through hole 8 of the first C-shaped keel 5 is penetrated by one end of the second C-shaped keel 6 provided with a rib, the end part of the second C-shaped keel 6 is slightly smaller than the normal height and is easy to pass through the through hole due to the rib pressing treatment, the thin second C-shaped keel 6 is easy to deform, is temporarily stressed, deformed and compressed and temporarily expanded transversely in the process of passing through the through hole, and can recover the height and width after passing through the through hole, the second C-shaped keel 6 is pulled out to the junction with the first C-shaped keel 5 by external force to be at a preset junction position, and the junction second C-shaped keel 6 is compressed by 2-6mm due to the rib pressing treatment, so that the junction second C-shaped keel 6 is not kept in a nested state with the first C-shaped keel 5 by external force, and the first C-shaped keel 5 and the second C-shaped keel 6 in the nested state cannot deform. And the overlapping positions of the flanges of the first C-shaped keels 5 and the second C-shaped keels 6 are fastened and connected by self-tapping screws to form the steel keel assembly frame 1.
The cushion plate layer 2 and the heat-insulation sound-insulation module 3 are cut in the set size of the standardized floor slab module, so that the cushion plate layer 2 covers the whole floor slab module, a screw reserved hole is formed in the screw fastening position of the cushion plate layer and the steel keel assembly frame 1, and the heat-insulation sound-insulation module 3 is arranged in a rectangular space just filled in the steel keel assembly frame 1.
The top surface of the steel keel assembly frame 1 is fixedly connected with the cushion board layer 2 through self-tapping screws, the rectangular space of the steel keel assembly frame 1 is filled with the heat-insulation and sound-insulation module 3, and the steel pull belt 4 is fixed below the steel keel assembly frame 1 through the self-tapping screws, so that the steel pull belt 4 supports the heat-insulation and sound-insulation module 3.
The invention is a complete product after factory manufacture, only needs to be assembled on site, does not need to be processed and manufactured, avoids dynamic welding operation, solves the problem of large field workload, reduces construction procedures, does not generate a large amount of construction waste, and has higher material recycling rate and lighter environmental pollution.
