Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a high-strength lightweight composite floor slab suitable for rapid industrialized dry construction and a floor slab layer system thereof. Background Art

[0002] With the improvement of economic level and the acceleration of urbanization, the scale of construction in the whole society is getting larger and larger, which also puts higher requirements on construction cost and construction efficiency. Buildings usually have more than one floor, and a floor needs to be set between two adjacent floors to separate the two floors. The load-bearing part of the floor layer divides the house into several floors in the vertical direction, and transmits the vertical loads such as people and furniture and the weight of the floor through walls, beams or columns to the foundation.

[0003] In the existing housing construction technology, the floor slabs of lightweight housing structures are mainly cast-in-place reinforced concrete slabs, which have the advantages of good stability and high structural strength. Cast-in-place reinforced concrete slabs require multiple construction processes such as formwork, steel bar binding, concrete pouring, maintenance, and formwork removal at the construction site. After the floor slab concrete reaches the designed strength, the superstructure can be installed.

[0004] However, the inventors of this application found that the above technology has at least the following technical problems in the process of implementing the technical solution of the invention in the embodiment of this application:

[0005] 1. Reinforced concrete floor slabs are heavy in weight. In addition to high requirements for vertical load-bearing components, they also require large machinery to participate in construction. They are not suitable for areas with restricted road conditions and have a great impact on the construction site environment. At the same time, the technical requirements for on-site installation are high and ordinary workers cannot operate them.

[0006] 2. Reinforced concrete floor slabs have complex construction procedures and a long construction period. Generally, they require normal maintenance for about 7-10 days before they can be demolded. The maintenance time in winter is even longer, requiring 10-15 days before they can be demolded, and the construction efficiency is low.

[0007] 3. Reinforced concrete floor slabs can only be used once. After installation, they cannot be dismantled and reused. This can easily generate a large amount of construction waste, causing waste of resources, and does not meet the requirements of green environmental protection and civilized construction advocated by modern society. Summary of the invention

[0026] 1. A new type of steel plate pallet with a frame and a bottom is designed.

[0043] The embodiments of the present application provide a high-strength lightweight composite floor slab and a floor slab layer system thereof, thereby solving the technical problems in the prior art of reinforced concrete floor slabs having heavy weight, complex construction process, high technical requirements, long construction period, and single-use only. The weight of the floor slab is greatly reduced, the construction process is simple, the technical requirements for on-site installation are low, the construction period is short, and the floor slab can be dismantled and reused, thereby meeting the requirements of green environmental protection and civilized construction.

[0044] The technical solution in the embodiment of the present application is to solve the above-mentioned crosstalk problem, and the overall idea is as follows:

[0045] Polystyrene particle foam concrete board is a commonly used lightweight wall panel material. It is made by pouring lightweight concrete and polystyrene particles into polystyrene particle foam concrete board, and then covering the two sides of the polystyrene particle foam concrete board with cement wood wool board. This type of lightweight wall panel material has the advantages of heat preservation, heat insulation, sound insulation, light weight, and meeting Class A fire protection standards. Therefore, it is widely used in lightweight wall systems. However, this material has the defects of being soft and fragile, and the strength of the wall panel made is limited, which is not suitable for construction conditions with high strength requirements. At the same time, polystyrene particle foam concrete board can only be used for wet construction, and the labor cost of on-site construction is high and the construction time is long.

[0046] The steel bars of traditional reinforced concrete slabs are laid vertically, but polystyrene foam concrete does not have the strength to hold the bars, so there is no precedent for using polystyrene foam concrete in slabs.

[0047] Therefore, a new quadrilateral steel plate pallet is designed, which includes C-shaped steel plates on both sides. The upper and lower ends of the C-shaped steel plates on both sides are connected by transversely arranged pulling steel plates, and the middle upper sides of the C-shaped steel plates on both sides are also connected by transversely arranged pulling steel plates to form a quadrilateral frame. The wire mesh is fixed to the bottom of the quadrilateral frame by instant full-surface contact electric welding technology to form a "plate" with a frame and a bottom.

[0048] The wire mesh is a diamond mesh structure formed by steel bars crossing at 45 degrees. The wire mesh at the bottom and the C-shaped steel plates on both sides are stressed as a whole. Because instant full-surface contact electric welding technology is used, after the 45-degree diamond mesh is welded with the C-shaped steel plate, the force of the steel bars is cross-transmitted obliquely on the C-shaped steel plate of the quadrilateral frame, forming a high-strength steel plate tray that is stressed as a whole.

[0049] The specially designed quadrilateral steel plate pallet is fixed to the outside of the polystyrene particle foam concrete board, and then the cement wood wool board is fixed on the upper and lower surfaces of the steel plate pallet as a cover. The polystyrene particle foam concrete board and the cement wood wool board cover are connected by the self-adhesiveness of the cement wood wool board. At the same time, the cement wood wool board and the steel plate pallet are fixed by nailing, thereby reinforcing the strength of the entire floor.

[0050] Since a steel plate pallet is installed on the outside of the polystyrene particle foam concrete slab, the polystyrene particle foam concrete material can be used for the floor slab, and the resulting floor slab has the advantages of light weight and high strength.

[0051] Two adjacent floor slabs are connected by C-shaped steel plates on the side of the steel plate tray to form a large floor slab layer. Preferably, male and female tongue-and-groove C-shaped steel plates are designed at both ends of the floor slab, and the two adjacent floor slabs are connected by the male and female tongue-and-groove C-shaped steel plates, and the male and female tongue-and-groove of the two connected C-shaped steel plates are fixed with screws. In this way, not only can the positioning connection of the floor slab be achieved, but also the torsional strength of the floor slab layer system can be enhanced.

[0052] At the same time, when the floor slab is connected to the steel beam or steel column of the building, the steel plate pallet can be directly fixed to the steel beam or steel column with bolts. The connection is convenient and fast, which truly achieves dry operation and rapid industrialized construction without affecting the environment of the construction site. At the same time, the technical requirements for on-site installation are low, and a small number of ordinary workers can complete the operation, so the construction cost is low.

[0053] In addition, after installation and use, the floor slab provided in the embodiment of the present application can be dismantled and reused, and no construction waste will be generated, thus saving resources and complying with the requirements of green environmental protection and civilized construction advocated by modern society.

[0054] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] Figure 1 to Figure 3 They are respectively a schematic diagram of the overall structure, an exploded view and a cross-sectional view of the high-strength lightweight floor provided in this embodiment. The high-strength lightweight composite floor is composed of a polystyrene particle foam concrete board 1, a steel plate pallet 2, a cement wood wool board 3, nails 4 and other components.

[0056] The polystyrene particle foam concrete board 1 is cast by adding polystyrene particles to lightweight concrete. There are many boards of this material on the market, such as the "Koni Board" produced by Shanghai Kangni Building Materials Technology Co., Ltd. and the "Matsumoto Board" produced by Guangdong Songben Green Board Co., Ltd. The bulk density of the polystyrene particle foam concrete board 1 is less than 800kg / m 3 , it has the advantages of thermal insulation, heat insulation, sound insulation, light weight, and meeting Class A fire protection standards.

[0057] The steel plate tray 2 includes C-shaped steel plates 21 arranged on both sides, the upper and lower ends of the C-shaped steel plates 21 on both sides are connected by horizontally arranged pull-connecting steel plates 22, and the upper middle sides of the C-shaped steel plates on both sides are also connected by horizontally arranged pull-connecting steel plates 22 to form a quadrilateral frame. The steel wire mesh 23 is fixed to the bottom of the quadrilateral frame by instant full-surface contact electric welding technology to form a "plate" with a frame and a bottom.

[0058] The steel mesh 23 is a diamond mesh structure formed by steel bars crossing at 45 degrees. The steel mesh 23 on the bottom and the C-shaped steel plates 21 on both sides are subjected to force as a whole. Because instant full-surface contact electric welding technology is used, after the 45-degree diamond mesh is welded with the C-shaped steel plate, the force of the steel bars is cross-transmitted obliquely on the C-shaped steel plate of the quadrilateral frame, forming a high-strength steel plate tray with overall force.

[0059] The specially designed quadrilateral steel plate tray 2 is fixed to the outside of the polystyrene particle foam concrete board 1, and then cement wood wool boards 3 are fixed on the upper and lower surfaces of the steel plate tray 2 as covers.

[0060] Combination Figure 4 The C-shaped steel plate 21 includes a side steel plate 211, one end of which is vertically connected to one end of an upper horizontal steel plate 212, the other end of which is bent downward to form an upper auxiliary side plate 213, the tail of which is bent inward to form an upper hook 214; the lower end of the side steel plate 211 is connected to one end of a lower horizontal steel plate 215, the other end of which is bent upward to form a lower auxiliary side plate 216, the tail of which is bent inward to form a lower hook 217. The C-shaped steel plate 21 is a symmetrical structure.

[0061] Male and female tongue-and-groove grooves are respectively arranged on the side steel plates 211 of the C-shaped steel plates 21 on both sides of the steel plate tray 2. In this embodiment, the male and female tongue-and-groove grooves are respectively matched convex structures and concave structures.

[0062] The side surface of the polystyrene particle foam concrete slab 1 in the thickness direction is in close contact with the side steel plate 211 of the C-shaped steel plate 21. The upper horizontal steel plate 212 and the lower horizontal steel plate 215 of the C-shaped steel plate 21 are respectively in close contact with the upper and lower surfaces of the polystyrene particle foam concrete slab 1, and the upper auxiliary side plate 213 and the upper hook 214, the lower auxiliary side plate 216 and the lower hook 217 are all embedded in the polystyrene particle foam concrete slab 1.

[0063] During pouring, the polystyrene particle foam concrete, the steel plate tray 2, and the cement wood wool board 3 are all placed in the mold and cast in one piece. The cement wood wool board 3 itself has self-adhesiveness, the upper cement wood wool board 3 is attached to the upper surface of the polystyrene particle foam concrete board 1, and the lower cement wood wool board 3 is attached to the lower surface of the steel mesh 23. At the same time, the cement wood wool board 3 is connected and fixed to the C-shaped steel plate 21 of the steel plate tray 2 by nails 4, so as to further strengthen the strength of the entire floor slab and ensure that the cement wood wool board 3 will not fall off during the use of the floor.

[0064] The high-strength lightweight composite floor provided in this embodiment can be prefabricated into multiple modules and then transported to the construction site for assembly. During assembly, the male and female tongues and grooves of the side steel plates 211 of the C-shaped steel plates 21 of two adjacent floor plates are matched and tightly attached, and the side steel plates 211 of the C-shaped steel plates 21 of the two adjacent floor plates are fixed by screws 5 to form a large-area floor layer system, such as Figure 5 shown.

[0065] When the high-strength lightweight composite floor provided in this embodiment is connected to the steel column 7 of the building at the construction site, bolts 6 are sequentially passed through the steel column 7, the cement wood wool board 3, and the upper horizontal steel plate 212 or the lower horizontal steel plate 215 of the C-shaped steel plate 21 and fixed. Figure 5 The connection between the exterior wall panels and the steel columns is convenient and fast, which truly achieves dry operation and rapid industrialized construction, breaking through the limitation that the traditional polystyrene particle foam concrete panels are soft and fragile and can only be used for wet operations.

[0066] For places where windows are set, the side steel plate 211 of the outermost C-shaped steel plate 21 of the floor slab does not have a male and female tongue and groove, and can be directly set as a flat surface, such as Figure 6 At this time, in the outermost high-strength lightweight composite floor, the side steel plate 211 of the C-shaped steel plate 21 on the outer side of the steel plate tray 2 is a flat structure, and the side steel plate 211 of the C-shaped steel plate 21 on the inner side of the steel plate tray 2 is provided with a concave female tongue-and-groove or a convex male tongue-and-groove, and the specific structure is determined according to the specific application conditions.

[0067] It is worth noting that, according to different usage conditions, the polystyrene particle foam concrete board 1 in this embodiment can also be replaced by other lightweight wall core boards, and the cement wood wool board 3 in this embodiment can also be replaced by other covers.

[0068] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0069] 1. A new type of steel plate pallet with a frame and a bottom is designed. By adding a steel plate pallet to the outside of the polystyrene particle foam concrete slab, the defect of polystyrene particle foam concrete having no reinforcing bar holding force is overcome, so that the polystyrene particle foam concrete material can be used for floor slabs. The resulting floor slabs have the advantages of light weight and high strength.

[0070] 2. A wire mesh is set at the bottom of the steel plate pallet, and the wire mesh is designed as a diamond mesh structure formed by steel bars crossing at 45 degrees. The wire mesh at the bottom and the C-shaped steel plates on both sides are stressed as a whole. Using instant full-surface contact electric welding technology, after the 45-degree diamond mesh is welded to the C-shaped steel plate, the force of the steel bars is cross-transmitted obliquely on the C-shaped steel plate of the quadrilateral frame, forming a high-strength steel plate pallet with overall stress.

[0071] 3. When the floor slab is connected to the steel beam or steel column of the building, the C-shaped steel plate on the side of the steel plate tray can be directly fixed to the steel beam or steel column with bolts. The connection is convenient and fast, and it truly achieves dry operation and rapid industrialized construction. It does not affect the environment of the construction site. At the same time, the technical requirements for on-site installation are low, and a small number of ordinary workers can complete the operation, and the construction cost is low.

[0072] 4. Male and female tongues and grooves are respectively set on the C-shaped steel plates on both sides of the floor slab. The two adjacent floor slabs are connected through the C-shaped steel plates with male and female tongues and grooves, and the male and female tongues and grooves of the two connected C-shaped steel plates are fixed with screws. In this way, not only the positioning connection of the floor slab can be achieved, but also the torsional strength of the floor slab system can be enhanced.

[0073] 5. The polystyrene particle foam concrete board and the two cement wood wool board covers are not only connected by the self-adhesiveness of the cement wood wool board, but also connected to the C-shaped steel plates on both sides of the steel plate pallet by nailing. This strengthens the connection strength of the entire floor slab, and the cement wood wool board will not fall off during use, ensuring the quality of the floor slab.

[0074] 6. The high-strength lightweight composite floor provided in the embodiment of the present application can be pre-fabricated in a modular manner and can be assembled and connected at the construction site. It is suitable for rapid industrialized dry construction, greatly reduces labor costs, meets the requirements of rapid, precise and efficient construction, promotes the process of building industrialization, and has broad application prospects.
