Description

Technical Field

[0001] This application relates to the technical field of precast components, and particularly to a steel-wood composite floor slab. Background Art

[0002] Currently, the commonly used forms of building floor slabs are mainly reinforced concrete floor slabs and steel-concrete composite floor slabs, which have the disadvantages of large self-weight, long construction period, and great difficulty in installation and transportation.

[0003] Wood (including bamboo) has the advantages of light self-weight and high strength, and is very suitable for use as a structural material; steel has high strength and large stiffness, and is an ideal building structural material. If the two are combined organically, the bearing capacity and stiffness required for a building floor slab can be obtained with less material consumption, the weight of the floor slab system will be greatly reduced, and the danger of the building under earthquake action can be greatly reduced.

[0004] Steel and wood are both relatively ideal building structural materials, and each has different mechanical performance characteristics. Seeking a more reasonable combination method between the two materials and giving full play to the performance advantages of the two materials will be able to promote the healthy development of the construction industry. Utility Model Content

[0005] This application provides a steel-wood composite floor slab, which has good mechanical performance, light self-weight, high industrialization level, and fast construction. By setting the lining strips in this application, the overall strength and stiffness of the profiled steel sheet are enhanced, the deformation resistance ability of the profiled steel sheet is improved, and further the overall strength and stiffness of the steel-wood composite floor slab are improved. The technical solutions adopted in this application are as follows:

[0006] A steel-wood composite floor slab, comprising:

[0007] A profiled steel sheet, lining strips and a wooden board. The lining strips are arranged on both sides of the profiled steel sheet through connecting pieces, and the lining strips are perpendicular to the length direction of the profiled steel sheet; the lining strips on the same side of the profiled steel sheet are arranged at intervals along the length direction of the profiled steel sheet; the side of the lining strip away from the profiled steel sheet is connected with the wooden board.

[0008] By setting the lining strips and connecting the rib parts of the profiled steel sheet with the lining strips, the overall strength and stiffness of the profiled steel sheet are enhanced, the deformation resistance ability of the profiled steel sheet is improved, and further the overall strength and stiffness of the steel-wood composite floor slab are improved.

[0009] In some embodiments, the grain direction of the wooden board on one side of the profiled steel sheet is consistent with the length direction of the profiled steel sheet, and the grain direction of the wooden board on the other side of the profiled steel sheet is perpendicular to the length direction of the profiled steel sheet.

[0010] By arranging the wood boards on both sides of the profiled steel sheet in mutually perpendicular grain directions, the multi-directional load-bearing performance of the steel-wood composite floor slab can be improved. While ensuring the load-bearing performance of the steel-wood composite floor slab along its length direction, the load-bearing performance of the steel-wood composite floor slab along its width direction is improved, thereby enhancing the overall load-bearing performance of the steel-wood composite floor slab.

[0011] In some embodiments, the grooves of the profiled steel sheet are filled with thermal insulation and sound insulation materials.

[0012] By arranging thermal insulation and sound insulation materials in the grooves of the profiled steel sheet, the thermal insulation and heat insulation capacity and sound insulation capacity of the steel-wood composite floor slab are improved, enabling the steel-wood composite floor slab to be applicable to buildings with high requirements for thermal insulation and sound insulation.

[0013] In some embodiments, the wood board is a bamboo board.

[0014] It can be understood that the bamboo board is made of bamboo, and the growth cycle of bamboo is much shorter than that of other woods. Bamboo has high strength, high toughness and good elasticity. In addition, the shrinkage of bamboo is small, which can reduce the risk of cracking of the wood board.

[0015] In some embodiments, tenons and grooves are respectively provided on both sides of the wood board corresponding to the width direction of the steel-wood composite floor slab, so that two adjacent steel-wood composite floor slabs can be connected by tongue-and-groove joints.

[0016] By respectively arranging tenons and grooves on both sides of the wood board in the width direction, the wood boards on two adjacent steel-wood composite floor slabs can be connected by tongue-and-groove joints, ensuring the aesthetics of the assembled steel-wood composite floor slab. In addition, the tongue-and-groove connection between the wood boards reduces the risk of deformation and warping of the wood boards.

[0017] In some embodiments, both sides of the profiled steel sheet corresponding to the width direction of the steel-wood composite floor slab are closed by flanging.

[0018] Both sides of the profiled steel sheet in the width direction are closed by flanging, which can eliminate the process of sealing the two sides of the steel-wood composite floor slab in the width direction with plates, facilitating the simplification of the manufacturing process of the steel-wood composite floor slab and improving the manufacturing efficiency of the steel-wood composite floor slab.

[0019] In some embodiments, a number of blind holes are provided at a position on one side of the wood board close to the lining strip and corresponding to the lining strip. The number of blind holes corresponding to the same lining strip is arranged at intervals along the width direction of the wood board, and fixing pieces are buried in the blind holes; both the profiled steel sheet and the lining strip are provided with mounting holes, and the mounting holes correspond to the positions of the blind holes; the profiled steel sheet, the lining strip and the wood board are connected by bolts that sequentially pass through the profiled steel sheet and the lining strip and are screwed to the fixing pieces.

[0020] By embedding the fixing parts in the blind holes and using bolts to connect the profiled steel sheet, the lining strip and the wooden board simultaneously, the connecting parts composed of the fixing parts and the bolts are hidden under the outer surface of the wooden board, ensuring the aesthetics and integrity of the steel-wood composite floor slab. In addition, by using the connecting parts to connect the profiled steel sheet, the lining strip and the wooden board, the connection stability between the wooden board and the lining strip can be ensured.

[0021] In some embodiments, the wooden board is treated against corrosion and pests.

[0022] By using the wooden board treated against corrosion and pests, the service life of the wooden board is extended, and the cost of replacing the wooden board or the steel-wood composite floor slab is saved.

[0038] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings and other embodiments can be obtained.

[0039] To simplify the drawings, only the parts relevant to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. Additionally, to simplify the drawings for easier understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one of them is labeled. In this document, "one" not only means "only this one" but also can mean "more than one" situation.

[0040] It should be further understood that the term "and / or" used in the description of the present application and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0041] In this document, it should be noted that unless otherwise clearly specified and defined, the terms "install", "connect", and "join" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0042] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0043] Reference Figures 1 - 3 , the present application provides a steel-wood composite floor slab, including: profiled steel sheet 1, liner strip 2, and wood board 3. Liner strips 2 are arranged on both sides of the profiled steel sheet 1 through connectors 4, and the liner strips 2 are perpendicular to the length direction of the profiled steel sheet 1; the liner strips 2 on the same side of the profiled steel sheet 1 are arranged at intervals along the length direction of the profiled steel sheet 1; a wood board 3 is connected to the side of the liner strip 2 away from the profiled steel sheet 1.

[0044] Specifically, the wood board 3 can be bonded to the liner strip 2 by an adhesive method, or the wood board 3 can be connected to the liner strip 2 by using the connector 4, or even both of the above connection methods can be adopted simultaneously. When the wood board 3 and the liner strip 2 are connected by the connector 4, the connector 4 connecting the wood board 3 and the liner strip 2 can be the same connector 4 as the connector 4 connecting the profiled steel sheet 1 and the liner strip 2, or they can be independent connectors 4. The connector 4 can specifically be a rivet assembly, such as a blind rivet, especially a countersunk head blind rivet and a closed-end blind rivet, or it can be a bolt assembly or an anchor bolt assembly.

[0045] In this embodiment, the lining plate can specifically be a steel plate, an aluminum alloy plate, or a composite plate. It can be understood that by providing the lining strip 2 and using the lining strip 2 to connect the ribs of the profiled steel sheet 1, the overall strength and stiffness of the profiled steel sheet 1 are enhanced, the deformation resistance of the profiled steel sheet 1 is improved, and thus the overall strength and stiffness of the steel-wood composite floor are improved.

[0046] In one embodiment, the grain direction of the wooden board 3 on one side of the profiled steel sheet 1 is consistent with the length direction of the profiled steel sheet 1, and the grain direction of the wooden board 3 on the other side of the profiled steel sheet 1 is perpendicular to the length direction of the profiled steel sheet 1.

[0047] It should be noted that by arranging the grain directions of the wooden boards 3 on both sides of the profiled steel sheet 1 to be perpendicular to each other, the multi-directional load-bearing performance of the steel-wood composite floor is improved. While ensuring the load-bearing performance of the steel-wood composite floor along its length direction, the load-bearing performance of the steel-wood composite floor along its width direction is improved, and thus the overall load-bearing performance of the steel-wood composite floor is enhanced.

[0048] Reference Figures 1 - 3 , in one embodiment, the groove of the profiled steel sheet 1 is filled with a thermal insulation and sound insulation material 5. Specifically, the thermal insulation and sound insulation material 5 can be mineral (rock) wool, centrifugal resin glass wool, glass fiber needle felt, etc., or it can also be a foaming material, such as polystyrene foam or polyurethane foam, etc. It is easy to understand that by providing the thermal insulation and sound insulation material 5 in the groove of the profiled steel sheet 1, the thermal insulation and heat insulation ability and sound insulation ability of the steel-wood composite floor are improved, enabling the steel-wood composite floor to be applicable to buildings with high requirements for thermal insulation and sound insulation.

[0049] In one embodiment, the wooden board 3 is a bamboo board. It can be understood that the bamboo board is made of bamboo, and the growth cycle of bamboo is much shorter than that of other woods. Bamboo has high strength, high toughness, and good elasticity. In addition, the shrinkage of bamboo is small, which can reduce the risk of cracking of the wooden board 3. In other embodiments, the material of the wooden board 3 can specifically be beech, pine, oak, elm, or birch, etc.

[0050] Reference Figure 2 , Figure 3 , in one embodiment, tenons 6 and grooves 7 are respectively provided on both sides of the wooden board 3 corresponding to the width direction of the steel-wood composite floor, so that two adjacent steel-wood composite floors can be connected by tongue-and-groove joints. By respectively providing tenons 6 and grooves 7 on both sides of the wooden board 3 in the width direction, the wooden boards 3 on two adjacent steel-wood composite floors can be connected by tongue-and-groove joints, ensuring the aesthetics of the assembled steel-wood composite floor. In addition, the tongue-and-groove connection between the wooden boards 3 reduces the risk of deformation and warping of the wooden boards 3. It can be understood that the wooden board 3 can be a whole board or a spliced board according to the product size and application scenario. When using a spliced board, the plates are connected to each other by tongue-and-groove joints.

[0051] Reference Figure 2 、 Figure 3 In one embodiment, both sides of the profiled steel sheet 1 corresponding to the width direction of the steel-wood composite floor are closed by hemming. It should be noted that both sides of the profiled steel sheet 1 in the width direction are closed by hemming, which can eliminate the process of using plates to seal the two sides of the steel-wood composite floor in the width direction, facilitating the simplification of the manufacturing process of the steel-wood composite floor and improving the manufacturing efficiency of the steel-wood composite floor. In other embodiments, the steel-wood composite floor can also be sealed and edged with wooden square timbers.

[0052] Reference Figures 1 - 3 In one embodiment, a number of blind holes are provided on one side of the wooden board 3 close to and corresponding to the lining strip 2. The several blind holes corresponding to the same lining strip 2 are arranged at intervals along the width direction of the wooden board 3, and fixing members are buried in the blind holes; both the profiled steel sheet 1 and the lining strip 2 are provided with mounting holes, and the mounting holes correspond to the positions of the blind holes; the profiled steel sheet 1, the lining strip 2 and the wooden board 3 are connected by bolts that sequentially pass through the profiled steel sheet 1 and the lining strip 2 and are screwed to the fixing members.

[0053] Specifically, the fixing member can be a nut or an anchor bolt, etc. It can be understood that by burying the fixing member in the blind hole and using bolts to connect the profiled steel sheet 1, the lining strip 2 and the wooden board 3 simultaneously, the connecting member 4 composed of the fixing member and the bolt is hidden under the outer surface of the wooden board 3, ensuring the aesthetics and integrity of the steel-wood composite floor. In addition, using the connecting member 4 to connect the profiled steel sheet 1, the lining strip 2 and the wooden board 3 can ensure the connection stability between the wooden board 3 and the lining strip 2. It can be understood that the connection method of the fixing member and the bolt in this embodiment belongs to a type of back-bolt connection. In other embodiments, the installation of the wooden board 3 can also be completed by other back-bolt connection methods.

[0054] It should be noted that in other embodiments, the connection between the wooden board 3 and the lining board and the profiled steel sheet 1 can also be in the form of counterbored holes or through holes, which can provide better connection strength and is also more convenient for construction. However, even after beautification treatment, when the wooden board 3 on the top surface of the steel-wood composite floor is directly used as the ground, the holes on the wooden board 3 will inevitably have a certain impact on the aesthetics and integrity of the ground.

[0055] In one embodiment, the wooden board 3 is treated against corrosion and pests. By using the wooden board 3 treated against corrosion and pests, the service life of the wooden board 3 is extended, and the cost of replacing the wooden board 3 or the steel-wood composite floor is saved.

[0056] It is easily understood that this application uses green building materials as the main building materials, reducing carbon emissions during the construction process. In this application, by combining two main materials, namely wood (including bamboo) and profiled steel sheet 1, and making them work together, the material characteristics are fully utilized, the building material consumption is reduced, and resources are saved. Compared with the usual practice, the industrialization degree of this floor slab can be greatly improved. Most processes can be completed in a prefabrication factory with higher processing precision. Fast assembly construction can be realized at the building construction site. At the same time, in this application, the structural members and the building surface layer are integrated into one, eliminating the decoration construction of the floor and the ceiling. All of these can greatly shorten the project cycle and improve the construction precision. In addition, this application does not require wet construction and has a lighter self-weight, so it can be constructed in places with more stringent construction conditions, further reducing the project cost and the restrictions of the construction conditions on the project site selection. It is very suitable for application scenarios such as small and medium-sized buildings, complex terrain land use, temporary buildings, or the division or renovation of the internal space of a building with requirements for rapid construction and lightweight construction.

[0057] The adoption of wood and a highly industrialized construction process greatly reduces carbon emissions throughout the construction cycle. At the same time, the characteristics of the materials and the structure can also enable the building using this floor slab to have good low-energy consumption performance, reducing carbon emissions during the building's service life. This floor slab provides an excellent low-carbon building solution.

[0058] It should be noted that the above-mentioned embodiments can be freely combined according to needs. The above are only the preferred implementation manners of this application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of this application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this application.
