Description

Technical Field

[0001] The present application relates to the technical field of assembled components, and in particular to a novel supporting connecting rib and a combined rib and assembled plate using the connecting rib. Background Art

[0002] In modern building construction, precast concrete components are used more and more widely. Among them, prefabricated floor slabs have become a common choice for high-rise buildings and residential buildings due to their advantages such as fast construction speed and stable quality. The precast components in prefabricated floor slabs are combined with steel trusses and precast base plate structures or steel base plate structures.

[0003] A commonly used steel truss in the construction market includes two connecting bars and web bars. The web bars are formed into a wavy shape by continuously bending a whole steel bar back and forth, and the bending part is a bent part. The bent part on one side of the web bar is fixedly connected to one of the connecting bars, and the bent part on the other side is fixedly connected to another connecting bar. When casting the assembled prefabricated panel, the steel truss is erected sideways, one of the connecting bars and part of the web bars are buried in the prefabricated bottom plate, and the other connecting bar and the remaining part of the web bars are exposed, so as to cast and form a prefabricated component.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: the steel truss transmits force through continuous web reinforcement. Although it has high tensile performance, its compressive performance is weak. In addition, when casting prefabricated components, the steel truss needs to be erected laterally, which makes it difficult to ensure stability. Summary of the invention

[0005] In order to improve the compressive performance of prefabricated components and increase the stability of the steel structure when casting prefabricated components, the present application provides a new type of supporting connecting reinforcement.

[0006] The present application provides a novel supporting connecting rib and a combined rib and assembled plate using the connecting rib, which adopt the following technical solutions:

[0007] A novel supporting connecting rib and a combined rib and assembled plate using the connecting rib, comprising a top rib, a bottom rib and a supporting rib, wherein the top rib and the bottom rib are parallel to each other, a plurality of supporting ribs are arranged between the top rib and the bottom rib, all the supporting ribs are arranged at equal intervals along the length direction of the bottom rib, the supporting ribs are formed by symmetrically bending the entire rib, the top rib is fixedly connected to the top of the supporting rib, the top rib is symmetrically arranged on the supporting rib, the bottom rib is fixedly connected to the bottom of the supporting rib, and the bottom rib is symmetrically arranged on the supporting rib.

[0008] By adopting the above technical scheme, the support bars not only have the function of supporting the entire new support connecting bar frame, so that the top bars and the bottom bars are connected into a whole, maintaining their stability, and making the top bars or the bottom bars not easy to become unstable when subjected to force; the support bars also have the function of transmitting force, transmitting the force of the top bars to the bottom bars or transmitting the force of the bottom bars to the top steel bars, so that the new support connecting bars become an integral force-bearing component. In addition, the top bars and the bottom bars are symmetrically arranged on the support bars, and the support bars are formed by symmetrically bending the entire bar. The new support connecting bars have high symmetry in cross section and strong stability; and in the process of force transmission, the support bars evenly disperse the top pressure to both sides, which can provide a larger bearing capacity; the entire new support connecting bar has high compressive performance and can exert excellent mechanical properties.

[0009] Preferably, the top ribs and bottom ribs are connected to the supporting ribs by welding or riveting.

[0010] By adopting the above technical solution, the support ribs are reliably connected to the top ribs and the bottom ribs by welding or riveting, so that the entire new type of support connecting ribs forms a stable whole, further ensuring that the support ribs effectively transmit force between the top ribs and the bottom ribs.

[0011] Preferably, the supporting ribs are vertically arranged between the top ribs and the bottom ribs.

[0012] By adopting the above technical solution, the support bar is vertically arranged between the top bar and the bottom bar, so that the load on the top of the support bar is directly transmitted to the bottom of the support bar in the vertical direction, which helps to improve the vertical bearing capacity of the entire new support connecting bar.

[0013] Preferably, the supporting bars, top bars and bottom bars are made of plain round steel bars, threaded ribbed steel bars or plain round embossed steel bars.

[0014] By adopting the above technical solution, by selecting plain round steel bars, threaded ribbed steel bars or plain round embossed steel bars, different supporting environments can be adapted.

[0015] Preferably, the support rib includes a transverse portion, a vertical portion, and a bent portion, wherein the transverse portion is located at the top of the support rib, the vertical portions are bent at both ends of the transverse portion and are symmetrically arranged as a group, and the bent portion is located at the bottom of the support rib, and the bent portion is bent at one end of the vertical portion away from the transverse portion.

[0016] By adopting the above technical solution, the transverse part is the force-bearing body at the top of the entire new supporting connecting rib, and is transmitted to the bottom through the vertical part; the side wall of the bent part is welded to the bottom rib as a whole, which can help to increase the size of the welding point between the supporting rib and the bottom rib, thereby improving the strength of the welding point between the supporting rib and the bottom rib, and no matter whether the new supporting connecting rib is cast upright or inverted, it can have sufficient contact area with the mold, further improving the stability of the casting process.

[0017] Preferably, the top rib is provided as one or two. If the top rib is provided as one, the top rib is fixed at the inner center of the transverse portion; if the top rib is provided as two, one of the top ribs is fixed at the inner side of the bending part between the transverse portion and one of the vertical portions, and the other top rib is fixed at the inner side of the bending part between the transverse portion and the other vertical portion.

[0018] By adopting the above technical solution, when the top reinforcement is set to one, the steel bar consumption is small and the cost is saved; when the top reinforcement is set to two, the overall stability of the top of the new supporting connecting reinforcement is high.

[0019] Preferably, the bottom ribs are arranged as a group, and the bottom ribs are fixed on the side of the vertical portion or the bent portion.

[0020] By adopting the above technical solution, when welding the new supporting connecting ribs, the bottom ribs are arranged on the side of the vertical part, which is convenient for limiting all the supporting ribs from the side of the vertical part, and is more convenient for neatly arranging and welding the supporting ribs; when the new supporting connecting ribs are supporting, the bottom ribs are arranged on the bending part, and the integrity of the supporting connecting ribs is higher.

[0021] Preferably, the bottom ribs are arranged in multiple groups, and are arranged on the sides and the bending parts of the vertical parts of the bottom ribs.

[0022] By adopting the above technical solution, the bottom of the new supporting connecting rib has higher stability and the arrangement of the supporting ribs is also more orderly.

[0023] Preferably, the transverse portion is a straight steel bar segment or a steel bar segment bent outward in an arc shape.

[0024] Preferably, the support ribs are arranged obliquely between the top ribs and the bottom ribs, and the inclination directions of adjacent support ribs are opposite.

[0025] By adopting the above technical solution, the supporting ribs, top ribs and bottom ribs form a triangular or trapezoidal structure in the length direction of the new supporting connecting ribs, which helps to further improve the stress stability of the entire new supporting connecting ribs.

[0026] Preferably, the bent portions on adjacent supporting ribs directly abut against each other or leave a gap therebetween.

[0027] By adopting the above technical solution, when the bent parts on adjacent supporting bars directly abut each other, the top bar and a group of adjacent supporting bars form a triangular structure in the length direction of the new supporting connecting bar, which helps to further improve the stress stability of the entire new supporting connecting bar; and a gap is left between the bent parts on adjacent supporting bars, which reduces the consumption of steel bars and saves costs while ensuring the stability of the supporting bars, and blocks the mutual interference of the force transmission process between adjacent supporting bars.

[0028] In order to further improve the compressive performance of the prefabricated components, the present application also provides a combined rib using the above-mentioned connecting ribs.

[0029] The combined rib provided in this application adopts the following technical solution:

[0030] A composite rib comprises a first rib plate, on which a novel supporting connecting rib is arranged, the first rib plate is cast on the bottom rib or the top rib, and all the bottom ribs or all the top ribs on the novel supporting connecting rib are located inside the first rib plate.

[0031] By adopting the above technical scheme, after the first rib is cast on the new support connecting rib, an integrated component, namely, a composite rib, is formed. The first rib is a concrete slab containing steel bars, and the force transmission effect in the length direction of the composite rib is better. The stiffness composite calculation of the new support composite rib and concrete is performed. The composite rib has a large stiffness. The composite rib can be used for combined casting with assembled prefabricated floor slabs or prefabricated wall panel components again, which can greatly improve the overall stiffness of the prefabricated components, control cracks, and meet the deflection and crack control requirements of demoulding lifting, construction transportation, and hoisting construction. In addition, the prefabricated floor slab using the new support connecting rib composite rib has a large bearing capacity, which can expand the support spacing during the construction stage, reduce the use of scaffolding, and save the cost of construction measures.

[0032] Preferably, the first rib is cast using high performance concrete.

[0033] By adopting the above technical solution, high performance concrete has extremely high compressive strength and durability, and can significantly improve the overall structural performance of the combined first rib plate.

[0034] Preferably, a high-strength C-shaped ribbed expansion mesh is arranged inside the first rib plate.

[0035] By adopting the above technical solution, a high-strength C-shaped ribbed expansion mesh is pre-embedded in the first rib, which can greatly improve the impact resistance and avoid cracking and damage caused by excessive impact concentrated force as much as possible; significantly improve the impact resistance of the first rib, and ensure the overall mechanical properties of the prefabricated components and the cleanliness of the construction site.

[0036] In order to facilitate the pre-reservation and pre-embedding of water and electricity pipelines and post-casting layer steel bars during the construction process, the present application provides an assembled plate using the above-mentioned composite ribs.

[0037] The present application provides a prefabricated panel adopting the following technical solution:

[0038] An assembled plate comprises a prefabricated bottom plate and a second rib plate. The prefabricated bottom plate is provided with a plurality of the new type of supporting connecting ribs. The prefabricated bottom plate is cast together on all the bottom ribs or all the top ribs. Adjacent the new type of supporting connecting ribs are parallel to each other and spaced apart. The second rib plate is cast on all the bottom ribs or all the top ribs on each of the new type of supporting connecting ribs. The second rib plate is connected to the prefabricated bottom plate at intervals through the supporting ribs.

[0039] By adopting the above technical scheme, the introduction of combined ribs significantly increases the equivalent cross-sectional height of the precast plate, so that the stiffness and bearing capacity of the precast plate are greatly improved, and water and electricity pipelines and post-cast layer steel bars can be reserved and embedded in the gap between the second rib plate and the precast bottom plate or the gap between multiple combined ribs, and the water and electricity pipelines can also pass directly through the supporting bars, which is convenient for the layout of various water and electricity pipelines; and because the combined ribs have a large stiffness, the thickness of the precast plate can be reduced, saving the cost of precast components. Different from the traditional steel truss, the second rib plate is used instead of a single steel bar, which is more conducive to the stability of on-site construction workers, ensuring construction safety and efficiency.

[0040] Preferably, the prefabricated base plate is any one of a concrete solid base plate containing steel bars, a concrete solid base plate containing prestressed steel bars, or a concrete thin plate containing fiber mesh cloth, steel wire mesh, or ribbed expanded mesh.

[0041] In summary, the present application includes at least one of the following beneficial technical effects:

[0042] 1. By setting top reinforcement, bottom reinforcement and several supporting reinforcements, a new type of supporting connecting reinforcement is formed.

DETAILED DESCRIPTION

[0057] The following is combined with Figure 1-11 This application is described in further detail.

[0058] Example 1

[0059] This embodiment discloses a new type of supporting connecting rib. Figure 1, which includes top reinforcement 1, bottom reinforcement 2 and support reinforcement 3. The top reinforcement 1 and the bottom reinforcement 2 are parallel to each other. A plurality of support reinforcements 3 are arranged between the top reinforcement 1 and the bottom reinforcement 2. All support reinforcements 3 are arranged at equal intervals along the length direction of the bottom reinforcement 2. The support reinforcement 3, top reinforcement 1 and the bottom reinforcement 2 are made of plain round steel bars, threaded ribbed steel bars or plain round embossed steel bars. The top reinforcement 1 and the support reinforcement 3 are fixed by welding or riveting at the top.

[0060] Reference Figure 1 Each support rib 3 is formed by symmetrically bending a whole rib, and the support rib 3 includes a transverse portion 31, a vertical portion 32, and a bending portion 33. The transverse portion 31 is a straight steel bar segment, and the transverse portion 31 is located at the top of the support rib 3 and in the center of the entire support rib 3. The vertical portion 32 is bent at both ends of the transverse portion 31 and is symmetrically arranged as a group. The bending portion 33 is located at the bottom of the support rib 3, and the bending portion 33 is bent at one end of the vertical portion 32 away from the transverse portion 31. The top rib 1 is symmetrically arranged on the support rib 3, and specifically, one top rib 1 is arranged and fixed at the inner center of the transverse portion 31. The bottom rib 2 is symmetrically arranged on the support rib 3, and specifically, the bottom rib 2 is fixed on the bending portion 33.

[0061] Reference Figure 1 The support ribs 3 are inclined between the top ribs 1 and the bottom ribs 2, and the inclination directions of adjacent support ribs 3 are opposite. There is a gap between the bent portions 33 on adjacent support ribs 3. After the support ribs 3, the top ribs 1, and the bottom ribs 2 are combined, a trapezoidal structure is formed in the length direction of the new support connecting rib, which helps to improve the stability of the force of the entire new support connecting rib.

[0062] Principle of this embodiment: The support ribs 3, top ribs 1, and bottom ribs 2 are welded or riveted to form a whole, and the support ribs 3 can effectively transmit force between the top ribs 1 and the bottom ribs 2. The top ribs 1 and the bottom ribs 2 are symmetrically arranged on the support ribs 3, and the support ribs 3 are formed by symmetrical bending of the entire rib. The new support connecting ribs have high symmetry in the cross section, strong stability, and are not easy to become unstable during the force-bearing process. The support ribs 3 also have the function of transmitting force, transmitting the force of the top ribs 1 to the bottom ribs 2, or transmitting the force of the bottom ribs 2 to the top steel bars, so that the new support connecting ribs are called an integral force-bearing component with excellent mechanical properties.

[0063] Example 2

[0064] The difference between Example 2 of the present application and Example 1 is that: Figure 2 The support rib 3 is vertically arranged between the top rib 1 and the bottom rib 2. The load on the top of the support rib 3 is directly transferred to the bottom of the support rib 3 in the vertical direction, which helps to improve the vertical bearing capacity of the entire new support connecting rib.

[0065] Example 3

[0066] The difference between Example 3 of the present application and Example 1 is that: Figure 3 Two top ribs 1 are provided, one of which is fixed inside the bend between the transverse portion 31 and one of the vertical portions 32, and the other top rib 1 is fixed inside the bend between the transverse portion 31 and the other vertical portion 32. The top of the new supporting connecting rib provided in this embodiment has higher overall stability.

[0067] Example 4

[0068] The difference between Example 4 of the present application and Example 1 is: Figure 4 , the bottom rib 2 is fixed to the side of the vertical portion 32. When welding the new supporting connecting ribs, the bottom rib 2 limits all the supporting ribs 3 from both sides, making it easier for the supporting ribs 3 to be neatly arranged and welded.

[0069] Example 5

[0070] The difference between Example 5 of the present application and Example 1 is: Figure 5 The bottom rib 2 is fixed not only on the bending portion 33, but also on the side of the vertical portion 32. The bottom of the new supporting connecting rib provided in this embodiment has high overall stability.

[0071] Example 6

[0072] The difference between Example 6 of the present application and Example 1 is: Figure 6 The bent portions 33 on adjacent support ribs 3 abut against each other, and the top rib 1 and a group of adjacent support ribs 3 form a triangular structure in the length direction of the new support connecting rib, further improving the stress stability of the entire new support connecting rib.

[0073] Example 7

[0074] The difference between Example 7 of the present application and Example 1 is: Figure 7 The transverse portion 31 is a steel bar segment that is curved outward in an arc shape.

[0075] Example 8

[0076] This embodiment discloses a composite rib using any one of the novel supporting connecting ribs in Embodiments 1 to 7. Figures 1 to 9 , which includes a first rib 4, on which a new type of supporting connecting rib is arranged, the first rib 4 is cast on the top rib 1, and all the top ribs 1 are located inside the first rib 4. The first rib 4 is cast with high-performance concrete, the thickness of the first rib 4 is 15-30mm, and a high-strength C-shaped ribbed expansion mesh 41 is arranged inside the first rib 4.

[0077] Principle of this embodiment: Compared with the traditional steel truss, the ordinary steel truss is transformed into a composite rib of supporting connecting bars, and the single steel structure is transformed into a composite structure of steel and concrete. And all the support bars 3 are discontinuous and intermittent, and are cast as a whole with the first rib 4. Specifically, the symmetrical design of the support bars 3 makes the force transmission of the composite rib more uniform and effective, and all the support bars 3 are cast as a whole with the first rib 4 through effective anchoring. High-performance concrete itself has the characteristics of high strength and high durability, and can provide sufficient support when subjected to external forces. The first rib 4 made of high-strength concrete material allows all the support bars 3 to transmit force together, dispersing the local force on the supporting first rib 4 to each support bar 3, thereby improving the bearing capacity of the prefabricated component, and the bearing capacity is increased by more than three times. The composite structure combined with steel bars and concrete has significantly improved overall structural stiffness due to the bite transmission of force between the support bars 3 and the concrete, and can better resist external pressure and tension. The height is calculated by taking advantage of the larger elastic modulus of high-performance concrete and the cross-sectional height of the composite ribs of the supporting connecting bars, thereby increasing the overall stiffness, reducing deformation, improving the stiffness of the structure, and ensuring stability and safety during construction.

[0078] In addition, in the traditional construction process, objects such as steel bars, tools and equipment often impact prefabricated components. Therefore, by pre-embedding the high-strength C-shaped ribbed expansion mesh 41 in the composite rib, the impact resistance can be greatly improved to avoid cracking and damage caused by excessive impact concentrated force.

[0079] The support bar 3 is intermittently supported and integrated with the concrete casting, which improves the stability and deformation resistance of the structure. The stability of the prefabricated components is significantly improved, and they show high reliability in both manufacturing and construction.

[0080] Example 9

[0081] The difference between Example 9 of the present application and Example 8 is that: Figures 1 to 8 , Fig.10 The first rib 4 is cast on the bottom reinforcement 2, and all the bottom reinforcements 2 are located inside the first rib 4.

[0082] Example 10

[0083] This embodiment discloses an assembled plate using a combined rib in Embodiments 1 to 7. Figures 1 to 8 , Fig.11, including a precast bottom plate 5 and a second rib plate 6. The precast bottom plate 5 is provided with a plurality of new supporting connecting ribs. The precast bottom plate 5 is cast together on all the bottom ribs 2 or all the top ribs 1. The new supporting connecting ribs are parallel to each other and arranged at intervals. The second rib plate 6 is arranged on all the bottom ribs 2 or all the top ribs 1 on each new supporting connecting rib. The second rib plate 6 is connected to the precast bottom plate 5 at intervals through the supporting ribs 3. The precast bottom plate 5 is any one of a concrete solid bottom plate containing steel bars, a concrete solid bottom plate containing prestressed steel bars, or a concrete thin plate containing fiber mesh cloth, steel wire mesh, or a ribbed expanded mesh.

[0084] The principle of the embodiment of the present application is: during the on-site construction process, water and electricity pipelines and post-casting layer steel bars can be reserved and embedded in the gap between the second rib plate 6 and the prefabricated bottom plate 5 or the gap between multiple combined ribs, and the water and electricity pipelines can also pass directly through the support ribs 3, which is convenient for the layout of various water and electricity pipelines, and is more conducive to the stability of workers on the construction site, ensuring construction safety and efficiency. The introduction of the second rib plate 6 and the new support connecting ribs significantly increases the equivalent cross-sectional height of the prefabricated plate, which greatly improves the stiffness and bearing capacity of the prefabricated plate.

[0085] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
