Description

Technical Field

[0001] The present application relates to the technical field of composite beams, and in particular to a novel composite beam based on novel industrialization. Background Art

[0002] With the development of new industrialization, the construction industry is placing higher demands on the strength, durability, and construction efficiency of structural components. Traditional steel and concrete beams, when used alone, suffer from inherent drawbacks such as insufficient strength and complex construction. Composite beam technology, by synergizing the tensile strength of steel with the compressive strength of concrete, has become an effective solution. In related technologies, composite beam construction typically involves hardening and forming fully precast floor slabs, which are then directly placed on the top surface of the upper flange of pre-studded steel beams.

[0003] However, since the precast floor slab is a hardened finished product, it is impossible to effectively anchor the shear connector between its bottom surface and the upper flange of the steel beam (the pre-welded bolts fail due to lack of concrete wrapping after being pressed by the precast slab), and there is also a lack of the cast-in-place concrete overlay layer required to form a continuous compression flange. As a result, the steel-concrete interface only has physical support but no reliable shear force transmission mechanism.

[0004] This structural defect will require the steel beam to have an increased cross-section when performing calculations in order to meet the strength, stiffness, and stability requirements under the same load. However, the increase in cross-section will increase the amount of material used and increase costs.

[0005] Therefore, there is a problem that it is difficult to take into account both the structural requirements and the production costs of the composite beam, and a new composite beam based on new industrialization is urgently needed. Summary of the Invention

[0006] In order to take into account both the structural requirements and production costs of the composite beam, the present application provides a new composite beam based on new industrialization.

[0007] This application provides a new type of composite beam based on new industrialization, which adopts the following technical solutions: A new type of composite beam based on new industrialization, including: The steel beam comprises an upper flange, a web and a lower flange, wherein the upper flange and the lower flange are respectively arranged on both sides of the web along its own height direction; A bearing mechanism, disposed on the web; A prefabricated panel group is arranged on the supporting mechanism; A cast-in-situ layer is cast on the prefabricated panel group and the steel beam, and the cast-in-situ layer wraps the upper flange.

[0008] By adopting this technical solution, the upper and lower flanges of the steel beam are positioned on either side of the web along its height, providing the basic framework and load-bearing foundation for the entire composite beam. A load-bearing mechanism is installed on the web to support the precast panel assembly and ensure its stable placement. The cast-in-place layer is cast atop the precast panel assembly and steel beam, wrapping around the upper flange. This allows the precast panel assembly, steel beam, and cast-in-place layer to form a single load-bearing structure. This synergistically leverages the tensile strength of steel and the compressive strength of concrete, enhancing the strength and durability of the composite beam compared to traditional methods of using steel and concrete beams separately. Furthermore, compared to the related art method of hardening and forming precast floor slabs and directly overlaying them on the top surface of the pre-studded steel beam upper flange, this structure avoids the problem of the steel-concrete interface providing only physical support but no reliable shear force transmission mechanism. This eliminates the need to increase the cross-section of the steel beam to meet the strength, stiffness, and stability requirements under the same load, thereby reducing material usage and production costs, while balancing the structural requirements and production costs of the composite beam.

[0009] Optionally, a plurality of steel beams are provided, and the plurality of steel beams are spaced apart from each other. The supporting mechanism is provided between two adjacent steel beams. The prefabricated panel group includes two prefabricated panels and a hinge assembly. The hinge assembly is respectively connected to the two prefabricated panels, and the sides of the two prefabricated panels that are away from each other are respectively provided on the supporting mechanism.

[0010] By adopting this technical solution, multiple steel beams are spaced apart, with the load-bearing mechanisms corresponding to each beam. This layout effectively distributes the weight of the precast panel group, making the load distribution of the entire new composite beam structure more uniform and improving structural stability. The two precast panels connected by the hinge assembly can be rotated relative to each other using the hinge assembly. During installation, the two precast panels can be rotated to a specific angle to avoid interference with the upper flange of the steel beams, facilitate the insertion of the precast panels between the two steel beams, and cooperate with the load-bearing mechanisms, improving installation convenience.

[0011] Optionally, the bearing mechanism includes a support and a support member, the support is arranged on the web, the two ends of the support member are respectively arranged on two opposite supports, the prefabricated plate is arranged on the support, and the support member is located below the prefabricated plate and respectively contacts the two prefabricated plates.

[0012] By adopting the above technical solution, the supports are installed on the web, which can serve as the support foundation for the precast panels. The two ends of the support member are respectively installed on two opposing supports, located below the precast panels and contacting the two precast panels. They can directly provide support for the precast panels, allowing the precast panels to be stably installed on the supports, sharing the load borne by the precast panels, and enhancing the stability of the precast panel installation, thereby improving the stability and load-bearing capacity of the entire new composite beam structure.

[0013] Optionally, a plug-in slot is provided on the support, and the support member is inserted into the plug-in slot.

[0014] By adopting the above technical solution and setting the plug-in slot, it is convenient to place the support member on the support.

[0015] Optionally, a snap-in groove is provided on the support, a snap-in block is provided on the prefabricated panel, the snap-in block is inserted into the snap-in groove, a one-way component is provided between the snap-in block and the inner wall of the snap-in groove, and the one-way component is used to prevent the snap-in block from detaching from the snap-in groove.

[0016] By adopting the above technical solution and the setting of the one-way component, the clamping block can be smoothly inserted into the clamping groove and prevented from being separated from the clamping groove, so that the prefabricated panel can be firmly set on the support, reducing the situation of the prefabricated panel accidentally falling off from the support, improving the stability and reliability of the overall structure of the new composite beam, reducing the safety risks caused by loosening or falling of the prefabricated panel, and in the long-term use process, it can ensure that the prefabricated panel is always in a stable installation state, which is conducive to maintaining the normal working performance of the composite beam, while reducing the maintenance and replacement costs caused by component displacement.

[0017] Optionally, a sliding groove is provided on the inner wall of the snap-fit ​​groove, the size of the sliding groove gradually decreases, and the smaller end of the sliding groove is arranged close to the notch of the snap-fit ​​groove. The one-way component includes an elastic member and a ball, and the elastic member and the ball are respectively arranged in the sliding groove, and the ball is connected to the elastic member. An inclined guide surface is provided on the snap-fit ​​block, and the ball is respectively fitted with the guide surface and the inner wall of the sliding groove.

[0018] By adopting the above technical solution, when the clamping block is inserted into the clamping groove, the inclined guide surface on it pushes the ball bearings toward the bottom of the clamping groove, so that the ball bearings do not interfere with the insertion of the clamping block, facilitating the smooth insertion of the clamping block into the clamping groove. When the clamping block is about to detach from the clamping groove and move outward, as the size of the chute gradually decreases and the small end approaches the slot opening, the ball bearings move from the large end of the chute to the small end, and then gradually press against the inner wall of the chute and the guide surface of the clamping block, using friction to prevent the clamping block from detaching from the chute, thereby achieving reliable positioning of the prefabricated panel on the support. This eliminates the need for additional anchors, simplifies the installation process, reduces costs, and ensures the stability and reliability of the composite beam structure.

[0019] Optionally, the hinge assembly includes a connecting shaft and two connecting parts, the connecting shaft is located between the two prefabricated panels and is rotatably connected to the two connecting parts respectively, the end of the connecting part away from the connecting shaft is movably connected to the prefabricated panel, and an elastic sleeve is coaxially sleeved on the connecting shaft, and the elastic sleeve is respectively in contact with the two prefabricated panels, and the elastic sleeve is used to fill the gap between the two prefabricated panels.

[0020] By adopting the above technical solution, the connecting shaft is rotatably connected to the two connecting parts, and the end of the connecting part away from the connecting shaft is movably connected to the precast panel, so that the two precast panels can rotate relative to each other around the connecting shaft. When the precast panels are connected to the support, the two precast panels can be rotated into a V shape to avoid interference with the upper flange, making it easier for the precast panels to enter the two steel beams and contact the support parts. After that, the precast panels are rotated to a horizontal state to facilitate the placement of the precast panels. At the same time, the elastic sleeves coaxially arranged on the connecting shaft respectively contact the two precast panels and fill the gap between them, so that there is a certain amount of movable margin between the two precast panels. On the one hand, it can compensate for the displacement caused by concrete shrinkage through active displacement or deformation, reducing the possibility of concrete cracking. On the other hand, it can absorb vibration energy and improve the seismic performance of the overall structure.

[0021] Optionally, movable grooves are respectively opened on the end surfaces of the two prefabricated panels that are close to each other, and the elastic sleeves are respectively inserted into the two movable grooves and fit against the inner walls of the movable grooves.

[0022] By adopting the above technical solution, the elastic sleeve is inserted into the movable groove and fits against the inner wall of the movable groove, so that the elastic sleeve can fill the gap between the two prefabricated panels and makes it less likely for the elastic sleeve to interfere with the rotation of the two prefabricated panels, so that the two prefabricated panels can rotate smoothly, and the elastic sleeve can be elastically deformed, so that there is a certain amount of movable margin between the two prefabricated panels. On the one hand, it can compensate for the displacement caused by concrete shrinkage through active displacement or deformation, thereby reducing the possibility of concrete cracking. On the other hand, it can absorb the energy of vibration and improve the seismic performance of the overall structure.

[0023] Optionally, a dovetail groove is provided on the support, and a dovetail block is provided on the prefabricated plate. The dovetail block is inserted into the dovetail groove, and the dovetail block is spaced apart from the inner wall of the dovetail groove.

[0024] By adopting the above technical solution, the dovetail block is inserted into the dovetail groove and spaced apart from the inner wall of the dovetail groove. On the one hand, the dovetail block is not easy to interfere with the slight displacement of the precast panel, so that the precast panel can compensate for the displacement caused by concrete shrinkage through active displacement or deformation. On the other hand, concrete can be poured in the gap between the dovetail block and the inner wall of the dovetail groove to further enhance the connection stability between the precast panel and the support, thereby improving the structural stability and reliability of the entire new composite beam, and better taking into account the construction requirements and production costs of the composite beam.

[0025] Optionally, reinforcing ribs are provided between the support, the lower flange and the web.

[0026] By adopting the above technical solution, reinforcing ribs are arranged between the support, the lower flange and the web. The reinforcing ribs can play a supporting and reinforcing role, enhance the connection stability between the support and the lower flange and the web, and make the entire bearing mechanism more stable, thereby improving the overall structural stability and reliability of the new composite beam, better bearing load, reducing the possibility of structural damage due to uneven force or external force impact, reducing the risk of structural deformation and damage, and ensuring the safety and durability of the new composite beam in practical applications.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By placing the precast panel group on the load-bearing mechanism, which is then placed on the web, and then pouring a cast-in-place layer on the precast panel group and steel beam to wrap the upper flange, the precast panel group, steel beam, and cast-in-place layer can form an integrated load-bearing structure, solving the problem of the lack of a reliable shear force transmission mechanism at the steel-concrete interface. This eliminates the need to increase the beam cross-section, reduces production costs, and takes into account both the structural requirements and production costs of the composite beam. 2. The precast panels are connected by hinged components with a movable margin, which can compensate for concrete shrinkage and displacement, reduce the possibility of concrete cracking, and absorb vibration energy, thereby improving the seismic performance of the overall structure; 3. The clamping blocks of the prefabricated panels use one-way components and clamping grooves to achieve positioning, without the need for additional anchors, and the dovetail blocks and the inner walls of the dovetail grooves can be poured with concrete, which improves the stability of the overall structural connection.

[0035] The following is combined with Figures 1-6 This application is described in further detail.

[0036] The embodiments of the present application disclose a new type of composite beam based on new industrialization.

[0037] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] Example 1: Reference Figure 1 A new type of composite beam based on new industrialization includes a steel beam 1, a load-bearing mechanism 2, a precast panel group 3, and a cast-in-place layer 4. The load-bearing mechanism 2 is arranged on the steel beam 1, the precast panel group 3 is arranged on the load-bearing mechanism 2, and the cast-in-place layer 4 is cast on the precast panel group 3 and the steel beam 1, thereby achieving the beneficial effects of making the composite beam structure stable and reducing costs.

[0039] There are multiple steel beams 1, and the multiple steel beams 1 are arranged at intervals with each other. The steel beam 1 includes an upper flange 11, a web 12 and a lower flange 13. The upper flange 11, the web 12 and the lower flange 13 are integrally formed, and the upper flange 11 and the lower flange 13 are respectively arranged on both sides of the web 12 along its own height direction.

[0040] The upper flange 11 is typically a plate-like structure, located above the web 12 and made of high-strength steel. The lower flange 13 is also a plate-like structure, located below the web 12 and made of similar materials and construction as the upper flange 11. The web 12 is a rectangular flat plate with a certain thickness to ensure it can withstand significant compressive and tensile forces.

[0041] The support mechanism 2 includes supports 21. The number of supports 21 is equal to the number of webs 12, and one support 21 is fixedly connected to each web 12. In this embodiment, the supports 21 are fixedly connected to the webs 12 by welding and are made of high-strength steel. In other embodiments, the supports 21 can also be fixedly connected to the webs 12 by bolts.

[0042] The precast panel group 3 is placed on the support 21, and the cast-in-place layer 4 is cast on the precast panel group 3 and the steel beam 1 and wrapped around the upper flange 11, thereby solving the shear force transmission problem at the steel-concrete interface. There is no need to increase the cross-section of the steel beam 1, reducing the amount of material used, and thus achieving the beneficial effect of making the composite beam structure stable and reducing costs.

[0043] A reinforcing rib 5 is fixedly connected between the bottom of the support 21 and the lower flange 13 and the web 12. The material of the reinforcing rib 5 is the same as that of the support 21, so that the stability of the support 21 can be improved through the reinforcing rib 5, so that it can better support the weight of the prefabricated panel group 3.

[0044] The cast-in-place layer 4 is poured after the precast panel group 3 and the steel beam 1 are installed. It uses concrete material and wraps the upper flange 11 during the pouring process, so that the steel beam 1 and the precast panel group 3 form an integral force-bearing structure, thereby enhancing the stability and integrity of the composite beam.

[0045] The implementation principle of a new composite beam based on a new type of industrialization in this embodiment is as follows: first, a steel beam 1 is installed in a designated position, then a precast panel group 3 is placed on a support 21, and finally, a cast-in-place layer 4 is poured, tightly combining the steel beam 1 and the precast panel group 3 to jointly bear the load. This combination method enables the various structural components to cooperate with each other, effectively leveraging the characteristics of steel and concrete, improving the performance of the composite beam, and simultaneously reducing unnecessary material waste and costs.

[0046] Example 2: Reference Figure 2 The difference between this embodiment and embodiment 1 is that the supporting mechanism 2 further includes a support member 22 , and the prefabricated panel set 3 includes two prefabricated panels 31 and a hinge assembly 32 .

[0047] In this embodiment, the precast panels 31 are concrete precast panels with regular shapes and good strength. Hinge assemblies 32 are connected to the two precast panels 31, allowing them to rotate relative to each other. This facilitates rotating the two precast panels 31 to a specific angle during installation to avoid interference with the upper flange 11. This further facilitates the insertion of the precast panels 31 between the two steel beams 1 and their placement on the supports 21, improving installation convenience.

[0048] A certain gap is reserved between the precast panel 31 and the support 21 to ensure that the precast panel 31 can be normally placed on the support 21 and that concrete can be filled into the gap, thereby ensuring the stability of the overall structure after construction is completed.

[0049] It should be noted that how to design the size of the gap reserved between the prefabricated plate 31 and the support 21 is a conventional technical means for those skilled in the art, so it will not be described in detail in the embodiments of this application.

[0050] Reference Figure 3 and Figure 4 The support 21 is provided with a plug-in slot 211, which is adapted to the shape design of the support member 22. In this embodiment, the support member 22 is a rod-shaped structure such as a steel bar. One end of the support member 22 can be inserted into the plug-in slot 211 on one support 21, and the other end of the support member 22 can be inserted into the plug-in slot 211 on the other support 21, so that the two relative supports 21 can jointly support the support member 22, so as to improve the stability of the support member 22.

[0051] The support member 22 is located at the bottom of the prefabricated panel 31 and can support the two prefabricated panels 31 so that the two prefabricated panels 31 are not easily rotated, thereby improving the stability of the overall structure.

[0052] Reference Figure 2 The hinge assembly 32 includes a connecting shaft 321 and two connecting members 322. The connecting shaft 321 is a cylindrical metal shaft with a smooth surface, which facilitates the rotation of the connecting members 322. The connecting members 322 are plate-like structures, one end of which is rotatably connected to the connecting shaft 321 and the other end is movably connected to the prefabricated panel 31, thereby enabling the prefabricated panel 31 to rotate about the connecting shaft 321.

[0053] In this embodiment, a protrusion is provided on the prefabricated panel 31, and a clearance groove is provided on the connecting member 322. The protrusion is inserted into the clearance groove and can rotate and slide within the clearance groove, thereby allowing a certain distance of displacement between the prefabricated panel 31 and the connecting member 322. In other embodiments, the prefabricated panel 31 and the connecting member 322 may also adopt other movable connection methods, based on ensuring that the prefabricated panel 31 can rotate with the rotation of the connecting member 322 and that the prefabricated panel 31 can be relatively displaced with the connecting member 322.

[0054] Reference Figure 5The two precast panels 31 are each provided with a movable groove 311 on their adjacent end surfaces. An elastic sleeve 323 is coaxially sleeved on the connecting shaft 321. The elastic sleeves 323 are respectively inserted into the two movable grooves 311 and fit closely against the inner walls of the movable grooves 311. In this embodiment, the elastic sleeves 323 are made of rubber, which has good elasticity and flexibility. This allows the elastic sleeves 323 to fill the gap between the two precast panels 31 and, to a certain extent, to cushion the relative movement between the two precast panels 31, reducing the possibility of concrete cracking while also absorbing vibration energy and improving seismic performance.

[0055] Reference Figure 4 A snap-fitting slot 212 is provided on the support 21, which is connected to the plug-in slot 211, and the snap-fitting slot 212 is located above the plug-in slot 211, so that the support member 22 can pass through the snap-fitting slot 212 and be inserted into the plug-in slot 211 to facilitate the installation of the support member 22.

[0056] A sliding groove 213 is defined on the inner wall of the engaging groove 212. The size of the sliding groove 213 gradually decreases, with the smaller end of the sliding groove 213 positioned closer to the notch of the engaging groove 212. A one-way assembly 23 is positioned within the sliding groove 213. The one-way assembly 23 includes an elastic member 231 and a ball 232. The elastic member 231 and the ball 232 are respectively positioned within the sliding groove 213, and the ball 232 is connected to the elastic member 231.

[0057] Reference Figure 3 and Figure 4 The prefabricated panel 31 is integrally formed with a clamping block 312, which is provided with an inclined guide surface 3121. When the prefabricated panel 31 is placed on the support 21, the clamping block 312 is inserted into the clamping groove 212, and the ball bearings 232 are respectively fitted with the guide surface 3121 and the inner wall of the slide groove 213.

[0058] When the clamping block 312 is inserted into the clamping groove 212, the guide surface 3121 pushes the ball 232 toward the larger end of the chute 213. At this time, the elastic member 231 is compressed and does not hinder the insertion of the clamping block 312. When the clamping block 312 attempts to be pulled out of the clamping groove 212, the ball 232 moves from the larger end of the chute 213 to the smaller end as the clamping block 312 moves. As the chute 213 gradually becomes smaller, the ball 232 tightly abuts against the inner wall of the chute 213 and the clamping block 312. The friction force confines the clamping block 312 within the clamping groove 212, effectively fixing the prefabricated panel 31 without the need for additional anchors, simplifying the installation process while ensuring the stability and reliability of the composite beam structure.

[0059] The working principle of this embodiment is as follows: when the prefabricated panels 31 need to be placed on the support 21, the two prefabricated panels 31 are first rotated to a specific angle to avoid interference with the upper flange 11, and then the two prefabricated panels 31 are placed on the support 21 and the support member 22. Next, the two prefabricated panels 31 are rotated to a horizontal position, which drives the clamping blocks 312 to move, so that the clamping blocks 312 are inserted into the clamping grooves 212, so that the clamping blocks 312 can be limited by the balls 232, thereby completing the placement of the prefabricated panels 31.

[0060] In this embodiment, the connecting member 322 is movably connected to the precast panel 31, and the elastic sleeve 323 can undergo elastic deformation, so that there is a certain amount of movable margin between the two precast panels 31. Therefore, on the one hand, the displacement caused by concrete shrinkage can be compensated by active displacement or deformation, thereby reducing the possibility of concrete cracking. On the other hand, it can absorb the energy of vibration and improve the seismic performance of the overall structure, thereby making the composite beam more practical and economical while meeting the structural requirements.

[0061] Example 3: Reference Figure 6 The difference between this embodiment and embodiment 2 is that a dovetail groove 214 is provided on the support 21 , the dovetail groove 214 is located beside the snap-fit ​​groove 212 , and the smaller end of the dovetail groove 214 is connected to the snap-fit ​​groove 212 .

[0062] A dovetail block 313 is integrally formed on the clamping block 312. The size of the dovetail block 313 is smaller than the size of the dovetail groove 214. Therefore, after the dovetail block 313 is inserted into the dovetail groove 214, the dovetail block 313 is spaced from the inner wall of the dovetail groove 214, providing a certain amount of movable margin for the prefabricated panel 31, thereby ensuring that the prefabricated panel 31 can be placed normally.

[0063] Reference Figure 2 and Figure 6 When the precast panel 31 is placed and the cast-in-place layer 4 is poured, the poured concrete can fill the gap between the dovetail block 313 and the dovetail groove 214, making the connection between the precast panel 31 and the support 21 more stable.

[0064] The implementation principle of this embodiment is: the coordination of the dovetail block 313 and the dovetail groove 214 and the subsequent concrete pouring increase the connection area and friction between the precast panel 31 and the support 21, further improving the overall connection stability of the composite beam.

[0065] In another preferred embodiment, the clamping block 312 may not be provided, and the dovetail block 313 may be directly integrally formed on the prefabricated plate 31 .

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
