Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structure technology, and in particular to core mold floor deck structure. Background Technology
[0002] In the professional field of architectural engineering, core molds are a crucial internal structural element. Presented in a specific geometric shape, they are embedded within the floor slab system, collaborating with surrounding materials to form a core mold floor deck structure. This innovative structure fully leverages the advantages of core molds, demonstrating unique appeal in modern architectural projects such as high-rise office buildings and large commercial complexes, which have stringent requirements for spatial layout and load-bearing capacity. It has become a cutting-edge exploration direction driving advancements in architectural technology.
[0003] Traditional floor decking structures mainly consist of steel trusses, profiled steel sheets, and concrete. The steel trusses, as the core load-bearing component, bear the vertical loads from above the floor slab and effectively transfer them to the supporting structure, ensuring the overall structural stability. The profiled steel sheets provide a temporary working platform during construction, facilitating personnel movement and material storage. After the concrete is poured, they work in conjunction with the concrete to enhance the floor slab's bending resistance. The concrete fills the top of the profiled steel sheets, and after curing, forms a solid load-bearing surface to withstand the floor's service loads.
[0004] The existing technologies described above have shortcomings and drawbacks. After a building has been in use for a long time, if the floor decking is damaged in a localized area, the problematic panels urgently need to be replaced. Due to the lack of convenient disassembly capabilities, demolition work must be carried out using specialized cutting tools, which is undoubtedly a high-difficulty and high-risk operation. This not only requires highly skilled and experienced operators but also significantly increases the probability of safety accidents. During the operation, the floor decking and surrounding structures are highly susceptible to irreversible physical damage, such as edge damage caused by cutting and structural deformation caused by forced disassembly, resulting in a significant reduction in the overall integrity and stability of the structure. Therefore, a core-mold floor decking structure is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a core mold floor deck structure, which aims to improve the cumbersome construction of existing single core mold hollow floor slabs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a core mold floor deck structure, comprising a bearing plate, a large core mold body, and a small core mold body. The top of the bearing plate is uniformly threaded with multiple connectors. The connectors are internally provided with detachable components that are easy to disassemble. Two connecting steel bars are fixedly connected inside the connectors. A 310mm high truss is fixedly connected to the top of the bearing plate. The 310mm high truss is internally fixedly connected to the outside of the multiple connecting steel bars.
[0007] As a further description of the above technical solution: the detachable component includes a connector, a front end plate is fixedly connected to the front end of the connector, the front end plate has a front pin hole inside, a middle end plate is fixedly connected to the middle part of the connector, the middle end plate has a middle pin hole inside, an end end plate is fixedly connected to the rear end of the connector, the end end plate has an end pin hole inside, and a pin is slidably connected inside the connector.
[0008] As a further description of the above technical solution: two placement slots are provided in the middle of the connector, and two reinforcing protrusions are fixedly connected to the front and rear sides of the middle insertion plate;
[0009] As a further description of the above technical solution: the upper part of the large core mold is fixedly connected to the inside of the large core mold body, the lower part of the large core mold is fixedly connected to the inside of the large core mold body, the upper part of the small core mold is fixedly connected to the inside of the small core mold body, the lower part of the small core mold is fixedly connected to the bottom of the small core mold body, a plastic hook is fixedly connected to the rear side of the upper part of the large core mold, and the rear end of the plastic hook is fixedly connected to the front side of the upper part of the small core mold;
[0010] As a further description of the above technical solution: multiple support tubes are fixedly connected to the bottom of the bearing plate, and multiple threaded rods are fixedly connected to the bottom of the bearing plate;
[0011] As a further description of the above technical solution: multiple connecting steel bars are externally fixedly connected to the upper and lower sides of the large core mold body, and multiple connecting steel bars are externally fixedly connected to the upper and lower sides of the small core mold body. The multiple large core mold bodies and the multiple small core mold bodies are connected by multiple connecting steel bars.
[0012] This utility model has the following beneficial effects:
[0013] In this utility model, the construction of a standalone core mold hollow floor slab is cumbersome and does not meet the requirements of prefabricated construction. The core mold steel truss floor slab combines the core mold and steel truss together, making construction convenient and eliminating the need for on-site formwork. It belongs to prefabricated construction. The use of large and small core molds is suitable for floor slabs with a thickness of 300mm, and can be applied to floor slab thicknesses of 250mm to 600mm. It can be widely used in large-span public buildings such as schools. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Reference Figure 1 , Figure 3This utility model provides an embodiment of a core mold floor deck structure, including a load-bearing plate 1, which supports and bears other components. A large core mold body 4 is connected to a small core mold body 5 via plastic hooks 9, forming a complete core mold system that jointly participates in the stress and operation of the floor deck. The dimensions of the large core mold (length × width × height) are 400 × 340 × 240 mm. The dimensions of the small core mold body 5 are 400 × 140 × 240 mm. Multiple connectors 2 are evenly threaded on the top of the load-bearing plate 1, connecting and fixing reinforcing bars 3. The connectors 2 have easily detachable components inside. Two reinforcing bars 3 are fixedly connected inside each connector 2, connecting and fixing the components. A 310 mm high truss 6 is fixedly connected to the top of the load-bearing plate 1, mainly bearing the vertical load and transferring it to the load-bearing plate 1 and the supporting structure, while also enhancing the overall stability of the floor deck. To prevent localized deformation, the 310mm high truss 6 is internally fixedly connected to the outside of multiple connecting steel bars 3. The detachable components include a connector 2, with a front insert 201 and a fixing pin 209 fixedly connected to its front end. The front insert 201 has a front pin hole 202, through which a middle insert 203 and a fixing pin 209 are fixedly connected to the middle of the connector 2. The middle insert 203 has a middle pin hole 204, through which a middle pin hole 204 is formed. The rear of the connector 2... The end is fixedly connected with an end plate 205 and a fixing pin 209. The end plate 205 has an end pin hole 206 inside. The pin 209 is slidably connected inside the connector 2 to fix the connecting steel bar 3 inside the placement groove 207. The middle part of the connector 2 has two placement grooves 207 for fixing the connecting steel bar 3. The front and rear sides of the middle plate 203 are fixedly connected with two reinforcing ridges 208 to enhance the strength of the middle plate 203 and prevent deformation during the stress process.
[0021] Reference Figure 1 , Figure 2The large core mold body 4 is internally fixedly connected to an upper part 401 and a lower part 402. The small core mold body 5 is internally fixedly connected to an upper part 501 and a lower part 502. A plastic hook 9 is fixedly connected to the rear side of the upper part 401 of the large core mold, which is used to connect with the small core mold body 5, ensuring that the large core mold body 4 and the small core mold body 5 form a whole in the floor decking structure. The rear end of the plastic hook 9 is fixedly connected to the upper part 501 of the small core mold. On the front side, multiple support pipes 7 are fixedly connected to the bottom of the bearing plate 1, which can provide stable vertical support for the bearing plate 1. Multiple threaded rods 8 are fixedly connected to the bottom of the bearing plate 1. The threaded rods 8 have a threaded structure and can be used to adjust the height and level of the bearing plate 1 to adapt to different construction and use requirements. Multiple connecting steel bars 3 are externally fixedly connected to the upper and lower sides of the large core mold body 4. Multiple connecting steel bars 3 are externally fixedly connected to the upper and lower sides of the small core mold body 5. Multiple large core mold bodies 4 and multiple small core mold bodies 5 are connected by multiple connecting steel bars 3.
[0022] Working principle: When the bearing plate 1 needs to be repaired or replaced, the multiple holes of the connector 2 provide space for the pin 209 to move. In the normal connection state, the pin 209 passes through the front pin hole 202 of the front insert plate 201, the middle pin hole 204 of the middle insert plate 203, and the end pin hole 206 of the end insert plate 205, thereby firmly fixing the connecting steel bar 3 in the placement groove 207 and ensuring the stable connection of the entire structure.
[0023] During disassembly, the operator manually pushes the pin 209, causing it to slide along the inside of the connector 2, gradually disengaging from the front pin hole 202, the middle pin hole 204, and the end pin hole 206. As the pin 209 disengages, the front insert plate 201, the middle insert plate 203, and the end insert plate 205 lose the fastening constraint of the pin 209, releasing the previously tightly connected state and loosening the fixed connection with the connecting steel bar 3. At this point, the connector 2 can detach from the connecting steel bar 3, achieving the purpose of disassembly.
[0024] The installation process for connector 2 is the reverse. First, the pin 209 is passed through connector 2, so that the pin 209 wraps around the corresponding position of the connecting steel bar 3. Then, the pin 209 is passed through the front pin hole 202, the middle pin hole 204 and the end pin hole 206 in sequence to lock the connecting steel bar 3. This ensures that connector 2 is securely installed between the bearing plate 1 and other components, reconstructing a reliable connection system to ensure that the core mold floor deck structure functions properly. The two reinforcing convex strips 208 fixedly connected to the front and rear sides of the middle insert plate 203 not only effectively enhance the strength of the middle insert plate 203 when connector 2 is under normal load, preventing it from deforming under stress, but also ensure that the pin 209 plays its fixing role.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
