Description

Technical Field

[0001] This invention relates to the field of building technology, and more particularly to a ribbed floor slab. Background Technology

[0002] Cold-formed thin-walled steel structures, as a new type of prefabricated light steel structure, have been widely used in the construction industry in recent years due to their advantages such as lightweight, high strength, high degree of industrialization and prefabrication, and environmental friendliness. Given the current resource utilization situation in my country, developing cold-formed thin-walled steel structure housing from low-rise to multi-story buildings is more in line with the country's development conditions. Existing cold-formed thin-walled steel structure housing is limited by the weak load-bearing capacity and low bending stiffness of the horizontal structural steel frame, and lacks structural measures to meet the relevant connection requirements. Therefore, by adopting modular prefabrication assembly technology to industrially produce ribbed floor slabs into component modules, the ribbed floor slab structure of cold-formed thin-walled steel structure housing can achieve a standardized and large-scale manufacturing and construction method similar to "assembling cars or home appliances." This addresses the shortcomings of the poor applicability of horizontal structural components in existing technologies, thus providing an effective way to promote the development of cold-formed thin-walled steel structure housing in my country.

[0003] Currently, in multi-story and high-rise steel structure building systems, the commonly used ribbed floor slab applications both domestically and internationally include steel-lined ribbed floor slabs composed of alternating corrugated steel sheets as steel linings and cast-in-place concrete, as well as steel truss floor decks. Due to the large amount of concrete used in steel-lined ribbed floor slabs and steel truss floor decks, the amount of on-site wet work is significant, leading to high construction difficulty and the large self-weight of the ribbed floor slabs, thus failing to achieve true prefabricated construction. Although prefabricated cold-formed thin-walled ribbed floor slabs have gradually developed and been applied in practice, problems such as poor continuity, low degree of prefabrication, weak load-bearing capacity, and low bending stiffness remain unresolved. Summary of the Invention

[0004] This invention provides a ribbed floor slab to address the shortcomings of existing prefabricated cold-formed thin-walled ribbed floor slabs, such as poor continuity, low degree of assembly, weak load-bearing capacity, and low bending stiffness. It achieves a detachable ribbed floor slab with strong overall performance, high degree of assembly, good stress performance and bending stiffness, and meets the requirements for flexible space division, large span size, and multi-story light steel residential buildings. It is suitable for industrial production and modular construction.

[0038] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0039] This invention employs a modular splicing method for ribbed floor slabs. Individual modules can be prefabricated in a factory and then assembled into a whole. This industrialized production method offers high efficiency and simple, quick connections, significantly improving construction efficiency. In actual production, the modules are digitally and automatically processed, assembled, and connected via a factory assembly line, ensuring production quality and precision, reducing assembly difficulty, increasing production efficiency, and saving substantial labor costs. When maintenance is required, only the damaged ribbed floor slab module needs to be replaced, greatly enhancing the maintainability and practicality of ribbed floor slabs.

[0040] Furthermore, the ribbed floor slab of the present invention has the advantages of good bending resistance and bending stiffness, and clear and reasonable force transmission. The first and second slabs are vertically connected, with the upper second slab bearing the main load of the floor and then transferring the load to the ribbed floor beams. In actual construction, the slab components in the first and second slabs can be directly used as permanent formwork for casting. Simultaneously, due to the vertical arrangement of the first and second slabs, certain hollow strips are formed inside, which not only solves the problems of heavy self-weight, long concrete curing time, and large formwork usage in existing ribbed floor slabs, but also saves construction time and materials, resulting in good economic benefits.

[0041] Furthermore, this invention incorporates a first slab within the carrier and lowers it by a certain height, increasing the interior ceiling height to some extent. The smooth bottom of the ribbed floor slab also facilitates construction. Simultaneously, the first and second slabs are connected vertically and horizontally to form a unified whole with the adjacent carrier. Therefore, the ribbed floor slab of this invention effectively ensures the continuity and integrity of the ribbed floor slab and is suitable for large-span and multi-story light steel frame residential buildings.

[0063] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0064] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "first" and "second" are used to clearly indicate the product components and do not represent any substantial difference. The directions of "upper" and "lower" are based on the directions shown in the accompanying drawings. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances. Furthermore, "multiple" means two or more. In the specification, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0065] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0066] Reference Figures 1-12 The present invention provides a densely ribbed floor slab.

[0067] Figure 1 A structural schematic diagram of a ribbed floor slab provided in an embodiment of the present invention is illustrated. (Refer to...) Figure 1The present invention provides a ribbed floor slab comprising a structural plate 7000, a carrier 8000, and a plate assembly 9000.

[0068] The carrier 8000 includes multiple floor beams 8400, which are interconnected by connecting beams to form a rectangular frame. The connecting beams include four first connecting beams 8100, which are located at the four corners of the rectangular frame in a one-to-one correspondence. The floor beams 8400 are located between two adjacent first connecting beams 8100.

[0069] The plate assembly 9000 is disposed on a rectangular frame, including a first plate 9100 and a second plate 9200, with the first plate 9100 and the second plate 9200 disposed vertically at intervals on the rectangular frame;

[0070] Structural plate 7000 is disposed on top of the floor slab assembly 9000.

[0071] Specifically, the four first connecting beams 8100 are positioned one-to-one at the four corners of the rectangular frame. This can be understood as the openings of the four first connecting beams 8100 all facing the center of the rectangular frame, and the sides of the four first connecting beams 8100 are interconnected to form the four sides of the rectangular frame. That is, the sides of two adjacent first connecting beams 8100 are located on the same straight line, and the floor beams 8400 are also located on this straight line, connected to the first connecting beams 8100 by splicing. The number of floor beams 8400 on the same side can be selected according to the actual situation and is not limited thereto.

[0072] Structural plate 7000 is disposed on top of floor slab assembly 9000. When the first plate 9100 is located above the second plate 9200, structural plate 7000 is disposed on top of the first plate 9100, specifically by being connected via fastener 400. When the second plate 9200 is located above the first plate 9100, structural plate 7000 is disposed on top of the second plate 9200, specifically by being connected via fastener 400.

[0073] In the above structure, because this invention uses a modular splicing method for the ribbed floor slab, each module can be prefabricated in the factory and then assembled into a whole. This results in high industrial production efficiency, simple and quick connection, and significantly improved construction efficiency. In actual production, the modules are digitally and automatically processed, assembled, and connected via a factory assembly line, ensuring production quality and precision, reducing assembly difficulty, increasing production efficiency, and saving significant labor costs. When maintenance is required, only the damaged ribbed floor slab module needs to be replaced, greatly enhancing the maintainability and practicality of the ribbed floor slab.

[0074] Secondly, since the first slab 9100 contains the first slab body 9120 and the second slab 9200 also contains the second slab body 9220, both the first slab body 9120 and the second slab body 9220 can be used as ready-made formwork for concrete pouring. During the pouring process, construction can proceed directly without waiting excessively for concrete curing. Furthermore, the first slab 9100 and the second slab 9200 are vertically connected, forming a hollow section. This not only solves the problems of heavy self-weight, long concrete curing time, and large formwork usage in existing ribbed floor slabs, but also saves construction time and materials, resulting in significant economic benefits.

[0075] Reference Figure 1 In some embodiments of the present invention, at least two floor beams 8400 are provided between two adjacent first connecting beams 8100. The connecting beams also include a third connecting beam 8300 and four second connecting beams 8200. The four second connecting beams 8200 are provided in a one-to-one correspondence with the four end faces of the third connecting beam 8300. The third connecting beam 8300 is located inside the rectangular frame. The two ends of the second connecting beams 8200 located on the same straight line are respectively connected to two floor beams 8400 provided between two adjacent first connecting beams 8100. The other end of the second connecting beam 8200 is provided with a floor beam 8400 between it and the third connecting beam 8300.

[0076] Specifically, the dimensions of the floor beam 8400 between two adjacent first connecting beams 8100 can be adjusted according to the actual situation. The floor beam 8400 is set in the middle of the rectangular frame. At this time, the first connecting beam 8100, the second connecting beam 8200, the third connecting beam 8300, and the floor beam 8400 can be constructed into a beam skeleton structure. The structural form of the carrier 8000 can effectively increase the overall stability of the floor. This allows the floor structure to form a more stable force system in space, increasing the load-bearing capacity and seismic performance of the floor. Secondly, the sunken structure of the closely ribbed floor can maximize the use of space and reduce the total height of the floor. The floor structure forms more modular components in the plane, which not only solves the problems of uneven force transmission and poor stress performance at the connection nodes of floor beams in traditional cold-formed floor slabs, but also reduces the number of floor beams in traditional cold-formed thin-walled steel buildings to a certain extent, thus reducing the total amount of steel used in the floor. Furthermore, the structure of the floor slab is relatively simple to construct, and the construction period is relatively short, which greatly simplifies the traditional construction process, improves construction efficiency, and reduces construction costs.

[0077] It should be understood that the number of the first connecting beam 8100, the second connecting beam 8200, the third connecting beam 8300 and the fourth connecting beam 8400 included in the carrier 8000 can also be adjusted correspondingly according to actual conditions. For example, in some possible embodiments, the third connecting beam 8300 may be omitted, and the first connecting beam 8100, the second connecting beam 8200 and the floor beam 8400 are only spliced into a Japanese-shaped structure, a grid-shaped structure, etc. It should be noted that splicing of the structure by using some or all of the first connecting beam 8100, the second connecting beam 8200, the third connecting beam 8300 and the floor beam 8400 is all within the protection scope of the present invention, and the number of each of the first connecting beam 8100, the second connecting beam 8200, the third connecting beam 8300 and the floor beam 8400 used in the splicing process is not limited, and they are used according to actual needs.

[0078] Figure 2 It is a schematic structural diagram of the first connecting beam of the floor provided by an embodiment of the present invention; Figure 3 It is an exploded view of the first connecting beam of the floor provided by an embodiment of the present invention.

[0079] Reference Figure 2 and Figure 3 , in some embodiments of the present invention, the first connecting beam 8100 comprises:

[0080] an L-shaped upper cover plate 8110;

[0081] an L-shaped lower cover plate 8140, which is arranged spaced apart from the L-shaped upper cover plate 8110;

[0082] two web assemblies 300, wherein a first connecting cylinder 8130 is arranged between the two web assemblies 300, the two web assemblies are arranged perpendicular to each other and connected perpendicularly to each other, and the two web assemblies 300 and the first connecting cylinder 8130 are both arranged between the L-shaped upper cover plate 8110 and the L-shaped lower cover plate 8140;

[0083] a first cylinder reinforcing component 8120, which is arranged inside the first connecting cylinder 8130;

[0084] both ends of the L-shaped upper cover plate 8110 and the L-shaped lower cover plate 8140 are provided with connecting ports 500, and the first connecting beam 8100 is connected with the floor beam 8400 through the connecting ports 500.

[0085] It is understandable that the structure of the first connecting beam 8100 can be formed by perpendicularly splicing two floor beams 8400. The difference lies in that the splicing joint at the connection point of the two floor beams 8400 is set at a 45-degree angle, and a first connecting cylinder 8130 is formed at the connection point. A first cylinder reinforcement component 8120 is set inside the first connecting cylinder 8130. The first connecting beam 8100 mainly serves to vertically connect the two floor beams 8400, thereby splicing multiple floor beams 8400 into a rectangular structure. The structure and dimensions of the two end faces of the first connecting beam 8100 are the same as the structure and dimensions of the end faces of the floor beams 8400. The method of splicing the first connecting beam 8100 with the floor beams 8400 is the same as the method of splicing two floor beams 8400. The L-shaped top cover plate 8110 also has a first snap-fit ​​edge 8111, which is used to place the floor slab assembly 9000.

[0086] It should be noted that the specific structure of the web assembly 300 and the connection port 500 can be referred to the following embodiment of the floor beam 8400.

[0087] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the first connecting cylinder 8130 includes a first connecting cylinder plate 8131 and a second first connecting cylinder plate 8132 connected to each other. The first connecting cylinder plate 8131 and the second first connecting cylinder plate 8132 cooperate to form a first cavity. The first cylinder reinforcing member 8120 is disposed in the first cavity, and the second first connecting cylinder plate 8132 is provided with a first protrusion.

[0088] The first cylindrical reinforcement component 8120 includes a first cylindrical reinforcement member 8121. Each side of the first cylindrical reinforcement member 8121 near the web assembly 300 is provided with a first cylindrical fixing member 8122. A first cylindrical connector 8123 is provided between two adjacent first cylindrical fixing members 8122. The first cylindrical connector 8123 is used to connect the first protrusion.

[0089] Specifically, the first connecting cylindrical plate 8131 is located on the outer side of the connection point and is perpendicularly spliced ​​to form a right angle surface. This right angle surface is coplanar with the outer surface of the first cylindrical reinforcement component 8120. The second connecting cylindrical plate 8132 is located at the connection corner. The first cylindrical reinforcement component 8121 is a square cylindrical structure and is hollow inside. Two adjacent surfaces of the first cylindrical reinforcement component 8121 are respectively set towards the two web plate assemblies 300. Two first cylindrical fixing components 8122 are fixedly installed on each of the two surfaces, and the two first cylindrical fixing components 8122 are arranged symmetrically from top to bottom. The two first cylindrical fixing components 8122 on the upper surface of the two surfaces are set at the same height, and the upper first cylindrical fixing components 8122 on the two surfaces are arranged adjacent to each other, and the lower first cylindrical fixing components 8122 are also arranged adjacent to each other. The first cylindrical connector 8123 is located at the junction of the two surfaces.

[0090] Figure 4 A schematic diagram of the structure of the second connecting beam of the floor slab provided in an embodiment of the present invention is illustrated. Figure 5 An exploded view of the second connecting beam of the floor slab provided in an embodiment of the present invention is shown.

[0091] Reference Figure 4 and Figure 5 In some embodiments of the present invention, the second connecting beam 8200 includes:

[0092] T-shaped top cover plate 8210;

[0093] The T-shaped lower cover plate 8240 is spaced apart from the T-shaped upper cover plate 8210;

[0094] Three web plate assemblies 300 are provided, and a second connecting cylinder 8230 is provided between the three web plate assemblies 300. The three web plate assemblies 300 are connected to the second connecting cylinder 8230 in a T-shape. The three web plate assemblies 300 and the second connecting cylinder 8230 are both located between the T-shaped upper cover plate 8210 and the T-shaped lower cover plate 8240.

[0095] The second cylindrical reinforcement component 8220 is located inside the second connecting cylindrical body 8230;

[0096] The three ends of the T-shaped upper cover plate 8210 and the T-shaped lower cover plate 8240 are provided with connection ports 500, and the second connecting beam 8200 is connected to the floor beam 8400 through the connection ports 500.

[0097] It is understandable that the structure of the second connecting beam 8200 can be formed by splicing three floor beams 8400 in a T-shape (that is, two floor beams 8400 are located on the same straight line, and the third floor beam 8400 is set perpendicular to the other two floor beams 8400). The difference is that a second connecting cylinder 8230 is formed at the connection of the three floor beams 8400, and a second cylinder reinforcement component 8220 is set inside the second connecting cylinder 8230. The second connecting beam 8200 mainly serves to connect the three floor beams 8400 in a T-shape, and can then be combined with the first connecting beam 8100 and the third connecting beam 8300 to splice multiple floor beams 8400 into other structures such as a grid.

[0103] Cross-shaped top cover plate 8310;

[0104] A cross-shaped lower cover plate 8340 is provided at an interval from a cross-shaped upper cover plate 8310;

[0105] Four web plate assemblies 300 are provided, and a third connecting cylinder 8330 is provided between the four web plate assemblies 300.

The method of splicing the third connecting beam 8300 with the floor beams 8400 is the same as the method of splicing two floor beams 8400. The cross-shaped top cover plate 8310 also has a third locking edge 8311, which is used to place the floor slab assembly 9000. It should be noted that when the floor beam 8400, the second connecting beam 8200, the third connecting beam 8300 and the floor beam 8400 are spliced ​​together, the first locking edge 8111, the second locking edge 8211, the third locking edge 8311 and the retaining edge 110 on the floor beam 8400 will be spliced ​​together at the same time to form a closed edge, which facilitates the limiting of the floor slab assembly 9000.

[0122] The following provides an example of the assembly method for a ribbed floor slab.

[0123] Assembly method: The first connecting beam 8100, the second connecting beam 8200, the third connecting beam 8300, and the floor beam 8400 are spliced ​​together to form a grid structure, that is, there are four small square structures. The first snap-fit ​​edge 8111, the second snap-fit ​​edge 8211, the third snap-fit ​​edge 8311 in the middle of each small square, and the retaining edge 110 on the floor beam 8400 are spliced ​​together to form a closed edge. The edge of each small square is limited by the first plate 9100. The inner side of the first plate side frame 9110 around the first plate 9100 is fixed to each small square by bolts, that is, connected to the various connecting beams spliced ​​together to form a grid structure. The top of the grid structure can be fixedly installed with a second plate 9200, and the first plate and the second plate are vertically connected by fasteners 700. Finally, a structural plate 7000 is laid on top of the second plate 9200, and the second high convex plate 9222 of the second plate 9200 is vertically connected to the structural plate 7000 by fasteners 700.

[0124] Figure 11 The example shown is an exploded view of a floor beam provided in an embodiment of the present invention.

[0125] Reference Figure 11 The floor beam 8400 provided in this embodiment of the invention includes a first cover plate 100, a second cover plate 200, and a web assembly 300.

[0126] The first cover plate 100 is provided with a first opening;

[0127] The second cover plate 200 is provided with a second opening, which is spaced apart from the first cover plate 100, and a receiving space is formed between the first opening and the second opening.

[0128] The web assembly 300 is disposed in the receiving space and includes a first web 310 and a second web 320 connected to each other. A plurality of hollow protrusions are formed between the first web 310 and the second web 320, and the hollow protrusions are used to support the first opening and the second opening.

[0129] The above structure has the following advantages:

[0130] First, each hollow protrusion can withstand significant pressure and shear deformation, effectively dispersing and transferring loads, thus improving the structure's compressive strength and bending stiffness. Furthermore, a series of cavities are formed between the hollow protrusions, which absorb energy and disperse impact forces. Therefore, the hollow protrusions provide good seismic and impact resistance when subjected to impact or vibration. The hollow protrusion structure also exhibits isotropy, meaning it possesses similar mechanical properties in different directions. This allows the hollow protrusion structure to provide uniform mechanical properties during use. Consequently, the floor beams can achieve higher local buckling resistance, out-of-plane stiffness, and greater torsional, shear, and compressive strength, providing effective support and reinforcement.

[0131] Secondly, the hollow protrusion structure has a large cavity, thus achieving lightweight while maintaining strength. Based on the strong supporting performance of the above structure, the first cover plate 100, the second cover plate 200, and the web assembly 300 of this invention can be made from thin-walled cold-formed steel sheets, thereby saving material usage and significantly reducing production costs.

[0132] Specifically, the materials for the first cover plate 100, the second cover plate 200, and the web assembly 300 can be Q235 steel, Q345 steel, Q390 steel, or Q420 steel, etc. The first cover plate 100 and the second cover plate 200 can be U-shaped steels, with two U-shaped steels spaced vertically apart, and the spacing between the two side plates of the two U-shaped steels is the same. During installation, one end of the hollow protrusion of the web assembly 300 is fastened to the interior of one U-shaped steel using a fastener 400, and fits against the two sides of the U-shaped steel to ensure a tight connection between the U-shaped steel and the web assembly 300. The other end of the hollow protrusion of the web assembly 300 is similarly positioned inside another U-shaped steel. Furthermore, the two flanges of the U-shaped steel and the hollow protrusion of the web assembly 300 are tightly fitted together, and the connection between them can be achieved by fasteners 400 penetrating through the flanges of the U-shaped steel and the hollow protrusion of the web assembly 300. The fastener 400 may include one or a combination of self-tapping screws, self-drilling screws, rivets, rivets, one-way bolts and expansion bolts.

[0133] In some possible embodiments, the hollow protrusions can be arranged in one row or multiple rows along the length of the first cover plate 100. When there is one row of hollow protrusions, the outermost edges of all hollow protrusions are located on the same plane; when there are multiple rows of hollow protrusions, the outermost edges of the two outermost rows of hollow protrusions are also located on the same plane, thereby allowing them to better fit with the two sides of the U-shaped steel and increasing the tightness of the connection. Specifically, the hollow protrusions are cylindrical structures, and the shape of their cross-section can be polygonal, such as triangular, quadrilateral, pentagonal, or hexagonal.

[0134] See Figure 11 In some embodiments of the present invention, connection ports 500 are sleeved inside both ends of the first cover plate 100 and the second cover plate 200. The connection port 500 includes a limiting member 510 and a fixing member 520 connected to each other. The fixing member 520 is disposed against the limiting member 510 and is provided with a first connecting wing. The first connecting wing is disposed at the port of the first cover plate 100 or the second cover plate 200. The limiting member 510 is provided with second connecting wings on both sides against the fixing member 520. The second connecting wings are used to limit the connecting member 700.

[0135] Specifically, the fixing member 520 is a first U-shaped channel steel, and the two sides of the first U-shaped channel steel are the first connecting wings; the limiting member 510 is a second U-shaped channel steel, and the two sides of the second U-shaped channel steel are the second connecting wings. That is, the connecting port 500 is composed of the first U-shaped channel steel and the second U-shaped channel steel connected back to back by bolts, wherein the two sides of the limiting member 510 are symmetrically arranged vertically along its height direction, and the two sides of the fixing member 520 are symmetrically arranged along its length direction. In the specific connection, the fixing member 520 is inserted into the port facing the first cover plate 100 or the second cover plate 200, and then fixed by the fastener 400. After it is installed, the first cover plate 100 is located at the port of the first cover plate 100 or the second cover plate 200, which facilitates the subsequent assembly of the two floor beams. The first U-shaped channel steel and the second U-shaped channel steel have a height of 75mm, a thickness of 4mm, and a length of 148mm. Of course, the parameters mentioned above for the first and second U-shaped channel steels are not unique, and their specific dimensions of height, thickness and length can be designed according to actual conditions.

[0136] In the above structure, the first U-shaped channel steel is connected to the first cover plate 100 and the second cover plate 200, which not only provides fixed support for the two sides of the first cover plate 100 and the second cover plate 200, but also strengthens the weak part of the splice joint, thereby strengthening the connection at the splice of the two floor beams.

[0137] Figure 12 A schematic diagram illustrating the connection structure between two floor beams provided in an embodiment of the present invention is shown.

[0138] Reference Figure 12 In some embodiments of the present invention, a connector 700 is further included for connecting the second connecting wings on the two floor beams. Specifically, the connector 700 is a rectangular steel cylinder with two through openings. When connecting the connector 700 to the second connecting wing, a portion of the connector 700 can be inserted into the interior of the second connecting wing, while a portion protrudes from the first cover plate 100 and the second cover plate 200, facilitating its insertion into both ends of another floor beam during later assembly, thereby achieving the connection between the two floor beams. Correspondingly, after the connector 700 is inserted into the interior of the second connecting wing, the two can be fixedly connected by fasteners. It should be noted that the shape of the connector 700 is not limited to rectangular; any structure capable of limiting the position of the first connecting wing is acceptable.

[0139] In some embodiments of the present invention, the first cover plate 100 and the second cover plate 200 are both connected to the web plate assembly 300 by fasteners 400; the first cover plate 100 and the second cover plate 200 are connected to the corresponding connection ports 500 by fasteners 400; the first web plate 310 and the second web plate 320 are connected by fasteners 400; the limiting member 510 and the fixing member 520 are connected by bolts.

[0140] The unique floor beam splicing method described above allows for the disassembly and replacement of individual floor beams as needed, making maintenance and repair work more convenient. No damage to the original structure or use of special tools is required; repairs or replacements can be performed simply by disassembling the connecting parts. This invention features simple construction, convenient manufacturing, easy and reliable construction, and no need for on-site welding, making it more in line with my country's green building construction requirements. It can reduce on-site construction steps, lower construction difficulty, save construction costs, and conserve steel, making its application in prefabricated cold-formed thin-walled steel structure buildings of significant practical engineering value.

[0141] In some embodiments of the present invention, at least one of the first opening and the second opening is provided with a retaining edge 110. Specifically, this embodiment includes at least three schemes: Scheme 1: retaining edges 110 are provided only on both sides of the first opening; Scheme 2: retaining edges 110 are provided only on both sides of the second opening; Scheme 3: retaining edges 110 are provided on both sides of the first opening and the second opening. It should be noted that in Scheme 1, the first cover plate 100 and the second cover plate 200 are arranged vertically spaced apart, and the first cover plate 100 is located on top of the second cover plate 200. In Scheme 2, the first cover plate 100 and the second cover plate 200 are arranged vertically spaced apart, and the second cover plate 200 is located on top of the first cover plate 100. The retaining edge 110 is used to engage with the ribbed floor slab. When the ribbed floor slab needs to be installed, it can be overlapped on the retaining edge 110, and the ribbed floor slab can be fixedly connected to the carrier 8000 by fasteners 400.

[0142] The following provides the assembly method for the 8400 floor slab beam: (It should be noted that the step numbers below are for ease of description only and are not a strict requirement for their order.)

[0143] S1: The first web plate 310 and the second web plate 320 are fitted together and connected by fasteners 400.

[0144] S2: Place the connected first web plate 310 and second web plate 320 together between the first cover plate 100 and the second cover plate 200, and connect them with fasteners 400.

[0146] S10: Connect the connection ports 500 to both ends of the first cover plate 100 and the second cover plate 200; specifically, insert the fastener 520 facing the port of the first cover plate 100 or the second cover plate 200, and then fix it with the fastener 400. After installation, the limiting member 510 is located at the port of the first cover plate 100 or the second cover plate 200;

[0147] S20: Part of the connector 700 is fitted into the limiting member 510 of a floor beam and fixed by the fastener 400; then the other part of the connector 700 is fitted into the limiting member 510 of another floor beam and fixed by the fastener 400.

[0148] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
