Embodiment 1

[0033] see Figure 1-2 , the present invention provides a technical solution: the composite floor is composed of two straw plates 3 sandwiching two cold-formed thin-walled C-shaped steel 2, and the straw plate 3 and the cold-formed thin-walled C-shaped steel 2 are glued with high-strength structure The self-tapping screw 1 is driven into the 4 positions of the solidified cemented surface, and the longitudinal side of the floor is sealed 5 with 3 straw plates, and the upper and lower parts are connected by screws. There is a cavity in the composite plate, and the thermal insulation and sound insulation materials, and can also easily pass through wires and other pipelines. The straw plate 3 is a high-strength material, and the use of a solid cross section is not conducive to fully exerting its material strength. Since the bonding between the cold-formed thin-walled C-shaped steel 2 and the straw plate 3 can produce a good combination effect through the bonding of high-strength st...

Embodiment 2

[0035] An assembly method of a floor slab composed of cold-formed thin-walled C-shaped steel and straw plates:

[0036] S1, two straw plates are processed, and several barbs are respectively processed on the connecting surface of the straw plates and the cold-formed thin-walled C-shaped steel, and the barbs are engaged with the ribs of the cold-formed thin-walled C-shaped steel;

[0037] S2, cold-bending the upper and lower ends of the thin-walled C-shaped steel to cold-bend outward extensions, and processing several ribs on the upper and lower sides of the cold-formed thin-walled C-shaped steel connected with the straw plate;

[0038] S3, apply glue on the connecting working surface of the two straw plates;

[0039] S4, placing a plurality of cold-formed thin-walled C-shaped steels between two straw plates, and fixing and connecting the top straw plate and cold-formed thin-walled C-shaped steel upper and lower end cold-formed outward extensions through the self-tapping screws...

Embodiment 3

[0043] The production steps of the straw board include:

[0044] a, removing impurities from the collected cotton stalks and crushing them to screen out stalk particles with a length of 100 mm and a width of 20 mm, and drying until the moisture content is less than 5%;

[0045] b, mix 52% by weight of straw granules, 14% by weight of sawdust, 11% by weight of gypsum, 30% by weight of magnesium powder, 1.2% by weight of sulfuric acid solution and 0.5% by weight of glycerin, add 60% water, after stirring for 60 minutes, put it into the mold and form it in the press, after it is formed, slowly release the pressure, trim the semi-finished product taken out and dry it at 150°C for 2 days, and finally put it into the pressure maintenance mold , dried and cured for 15 days, the cotton straw board is obtained.

[0046] The connecting surface of the cold-formed thin-walled C-shaped steel 2 is provided with several ribs 8, and the connecting surface of the straw plate 3 is provided wit...

Abstract

The invention discloses a floor formed by combining cold-formed thin-wall C-shaped steel and straw plates and a manufacturing method. The combination floor is made from the two straw plates and the two pieces of cold-formed thin-wall C-shaped steel in a combination mode; the cold-formed thin-wall C-shaped steel is arranged between the straw plates, the straw plates and the cold-formed thin-wall C-shaped steels are bonded through high-strength structural adhesive, the high-strength structural adhesive forms the solidified bonded face, self-tapping screws for fixing the straw plates and the cold-formed thin-wall C-shaped steel are arranged at the solidified bonded face, sealing strips are arranged on the sides of the two straw plates and connected with the straw plates through screws, a plurality of rib strips are arranged on the connecting faces of the cold-formed thin-wall C-shaped steel, and a plurality of barbs are arranged on the connecting faces of the straw plates and engaged with the rib strips; the rigidity and the bearing capacity of a pure steel floor and a pure wood floor are improved, and the actual engineering requirements are met; the floor can be manufactured in a plant, site assembly is carried out, and the site construction time is largely shortened; the floor is compared with a traditional concrete floor ceiling and the like, and the self weight is small, the whole construction cost is low, the bearing capacity is high, and the ductility is good.

Description

technical field [0001] The invention relates to a floor slab combined with cold-formed thin-walled C-shaped steel and straw plates and a manufacturing method thereof. Background technique [0002] At present, the profiled steel plate-concrete composite floor is the most prominent and mature in the composite floor system. As early as the 1930s, people used the profiled steel plate as a permanent formwork, and then gradually began to realize To realize the combination effect of profiled steel plate and concrete, and use steel plate instead of reinforced steel bar, realize its superiority and gradually promote its use. Since the 1960s, the United States, Europe, the Soviet Union and other countries have formulated and issued design and construction standards for composite steel plates, which has greatly promoted the further research and application of composite steel plates. However, our country only started the research and application of composite floor slabs in the 1980s, a...
