Description

Technical Field

[0001] This utility model relates to the field of cylindrical support structure technology, and in particular to a reinforced concrete rest platform. Background Technology

[0002] In reinforced concrete cylindrical support structures, steel ladder rest platforms are usually provided. The construction of the cylindrical body is generally carried out by slipform construction. Due to the constraints of this construction process, the rest platform can only be built after the construction of the cylindrical body is completed.

[0003] Currently, there are generally two approaches to this rest platform:

[0004] 1. Steel Structure Solution: This involves pre-embedding components in the reinforced concrete cylinder. After the cylinder slipforming is completed, steel beams are welded to the embedded components, and steel plates are laid to form a steel platform. The disadvantages of this solution are that the steel structure is prone to corrosion, has poor durability, and requires high maintenance.

[0005] 2. Cast-in-place reinforced concrete scheme with pre-reserved reinforcing bars: During the construction of the cylinder body, reinforcing bars (reinforcing ribs) are pre-reserved for the concrete rest platform. After the cylinder body is slip-formed, the formwork is erected, the rest platform reinforcing bars are tied, and concrete is poured. The rest platform reinforcing bars are connected to the cylinder body via reinforcing ribs. The disadvantage of this scheme is that a construction joint is left between the rest platform and the cylinder body concrete. If the construction joint is not properly treated, the reinforcing bars are prone to corrosion, thus reducing the load-bearing capacity of the concrete platform.

[0006] Therefore, it is necessary to propose a reinforced concrete rest platform to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0008] To achieve the above objectives, this utility model provides a reinforced concrete rest platform, including a rest platform, a reinforcing component, and a concrete cylinder, wherein the reinforcing component is built into the rest platform; wherein,

[0009] The inner wall of the concrete cylinder has recesses forming multiple beam recesses spaced apart along its circumference; the rest platform includes platform slab segments and multiple concealed beam segments; the reinforcement components include platform slab reinforcement components and concealed beam reinforcement components; wherein,

[0010] The platform slab segment is recessed to form a ladder opening. Both ends of the concealed beam segment extend out of the platform slab segment and are located in the beam recess.

The concealed beam reinforcements extend along the extension direction of the concealed beam segment.

[0013] Preferably, the platform slab reinforcement assembly comprises multiple layers of platform slab reinforcement units arranged vertically at intervals, each layer of the platform slab reinforcement unit comprising multiple transverse reinforcement units arranged longitudinally at intervals and multiple longitudinal reinforcement units arranged transversely at intervals; wherein,

[0014] Each of the transverse reinforcement units includes two transverse reinforcements arranged opposite each other along the longitudinal direction, and each of the longitudinal reinforcement units includes two longitudinal reinforcements arranged opposite each other along the transverse direction. The longitudinal reinforcements overlap the transverse reinforcements, and the transverse reinforcements overlap the hidden beam reinforcements.

[0015] Preferably, the platform slab reinforcement assembly further includes multiple layers of slab edge sealing reinforcement units arranged vertically at intervals. Each layer of the slab edge sealing reinforcement unit includes multiple slab edge sealing reinforcements connected end-to-end along the circumferential direction of the platform slab segment. Among them, the two slab edge sealing reinforcements near the ladder opening are disconnected to form a C-shaped distribution of slab edge sealing reinforcement units. The slab edge sealing reinforcements overlap the hidden beam reinforcement.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This utility model provides a reinforced concrete rest platform, including a rest platform, a reinforcing component, and a concrete cylinder. The reinforcing component is built into the rest platform. The inner sidewall of the concrete cylinder has a recess forming multiple beam sockets spaced apart along its circumference.

[0034] Please see the appendix Figure 1-3 This utility model provides an embodiment of a reinforced concrete rest platform 10, comprising a rest platform 10, a reinforcing component 20, and a concrete cylinder 30, wherein the reinforcing component 20 is embedded within the rest platform 10. First, it should be noted that the horizontal and vertical directions in this application are indicated in the views for ease of explanation, as detailed below:

[0035] The inner wall of the concrete cylinder 30 is recessed to form multiple beam recesses 310 spaced apart along its circumference. The rest platform 10 includes a platform slab segment 110 and multiple hidden beam segments 120. The reinforcement component 20 includes a platform slab reinforcement component 210 and a hidden beam reinforcement component 220. The platform slab segment 110 is recessed to form a ladder opening 111. The two ends of the hidden beam segments 120 extend out of the platform slab segment 110 and are located in the beam recesses 310. A pouring layer 311 is provided between the two ends of the hidden beam segments 120 and the top and bottom of the beam recesses 310, respectively. The platform slab reinforcement component 210 is built into the platform slab segment 110. Each hidden beam segment 120 has a corresponding hidden beam reinforcement component 220 built into it. The platform slab reinforcement component 210 overlaps the hidden beam reinforcement component 220.

[0036] Specifically, the reinforced concrete rest platform 10 in this application includes a rest platform 10, a reinforcing component 20, and a concrete cylinder 30. The concrete cylinder 30 has multiple recesses 310 formed at the elevation where the rest platform 10 is to be installed. These recesses 310 can be formed by chiseling out after the slipforming construction of the cylinder at the elevation of the rest platform 10 and before the initial setting of the concrete. After the recesses 310 are formed, they can be used to place the rest platform 10. Preferably, the width of the recesses 310 can be set to 100mm to 120mm to facilitate the erection and connection. The rest platform 10 includes a platform slab segment 110 and multiple concealed beam segments 120. The platform slab segment 110 is the main body of the rest platform 10, while the concealed beam segments 120 are used to be erected in the beam sockets 310. Therefore, both ends of the concealed beam segments 120 need to extend beyond the platform slab segment 110 to be installed in the beam sockets 310. This ensures that the platform slab segment 110 does not directly contact the concrete cylinder 30, thus not affecting the stress on the cylinder. The reinforcing component 20 is used to reinforce the entire rest platform 10. The structural strength includes platform slab reinforcement assembly 210 and concealed beam reinforcement assembly 220. Platform slab reinforcement assembly 210 strengthens the structural strength of platform slab segment 110, while concealed beam reinforcement assembly 220 strengthens the structural strength of concealed beam segment 120. Conversely, concealed beam reinforcement assembly 220 also serves as a support for platform slab reinforcement assembly 210. This overlapping structure forms a reinforcement mesh. The reinforcement bars are not connected to the cylinder reinforcement during overlapping, thus avoiding construction joints and preventing corrosion of the reinforcement bars due to improper handling. After the reinforcing bars of the concealed beam segment 120 are tied and before pouring, a space is reserved between its two ends and the top and bottom of the beam socket 310 to set the pouring layer 311. This pouring layer 311 is used to be poured together with the concrete, thereby effectively ensuring the density of the concrete in the beam socket 310 and the slab thickness. The thickness of the pouring layer 311 can be set to 25mm to 27mm. In a preferred embodiment of this application, 25mm can be reserved at the top and bottom, and the slab thickness can be specifically calculated and set according to the actual diameter of the platform slab segment 110.

[0037] In a preferred embodiment of the present invention, there are four hidden beam segments 120 and eight beam recesses 310. The four hidden beam segments 120 are arranged in a grid pattern, and each hidden beam segment 120 has a beam recess 310 at both ends.

[0038] It should be noted that four hidden beam segments 120 are arranged in a grid pattern, forming two transverse hidden beam segments 120 and one longitudinal hidden beam segment 120. The grid pattern allows the beam segments in each direction to work together, sharing and distributing the load, resulting in more uniform stress on each beam, improving structural stability and load-bearing capacity, and ensuring more uniform deflection, which is beneficial for maintaining the structural performance. Therefore, the four hidden beam segments 120 form eight end pieces, corresponding to eight beam recesses 310, so that each end of the hidden beam segment 120 has one beam recess 310. Please refer to the appendix for details. Figure 1 .

[0039] In a preferred embodiment of the present invention, each of the concealed beam segments 120 includes a concealed beam reinforcement assembly 220 comprising multiple layers of concealed beam reinforcement units arranged vertically at intervals and multiple reinforcing bars 222 arranged at intervals along the extension direction of the concealed beam segment 120. Each layer of the concealed beam reinforcement unit includes two concealed beam reinforcements 221 respectively connected to both sides of the reinforcing bars 222. The concealed beam reinforcements 221 extend along the extension direction of the concealed beam segment 120.

[0040] It should be noted that in each of the concealed beam segments 120, the concealed beam reinforcement assembly 220 adopts a multi-layer concealed beam reinforcement unit and stirrup 222 combined structure. The multi-layer arrangement can better bear the bending moment and shear force in the slab, improve the overall load-bearing capacity of the slab, make the stress on the slab more uniform, reduce local stress concentration, and reduce the deflection of the slab. The stirrup 222 can serve as a reinforcement skeleton, so that the two concealed beam reinforcements 221 in each layer of concealed beam reinforcement unit are respectively lapped on both sides of the stirrup 222. It is worth mentioning that, considering that the multiple concealed beam segments 120 in this application adopt a grid-like distribution, the concealed beam reinforcements 221 in each of the concealed beam segments 120 extend along the extension direction of the concealed beam segment 120. That is, the concealed beam reinforcements 221 in the transverse concealed beam segment extend transversely, and the concealed beam reinforcements 221 in the longitudinal concealed beam segment extend longitudinally.

[0041] In a preferred embodiment of this utility model, the platform slab reinforcement assembly 210 includes multiple layers of platform slab reinforcement units arranged vertically at intervals. Each layer of the platform slab reinforcement unit includes multiple transverse reinforcement units arranged longitudinally at intervals and multiple longitudinal reinforcement units arranged transversely at intervals; wherein,

[0042] Each of the transverse reinforcement units includes two transverse reinforcements 211 arranged opposite each other in the longitudinal direction, and each of the longitudinal reinforcement units includes two longitudinal reinforcements 212 arranged opposite each other in the transverse direction. The longitudinal reinforcements 212 overlap the transverse reinforcements 211, and the transverse reinforcements 211 overlap the hidden beam reinforcements 221.

[0043] It is worth noting that, similar to the concealed beam reinforcement unit, the platform slab reinforcement unit also adopts a multi-layer arrangement. Thus, during lap splicing, each layer of the concealed beam reinforcement unit is also lapped with a corresponding layer of the platform slab reinforcement unit. Each layer of the platform slab reinforcement unit includes multiple transverse reinforcement units spaced longitudinally and multiple longitudinal reinforcement units spaced transversely, forming a two-way arrangement. This bidirectional arrangement allows for the shared and even distribution of loads, resulting in better structural stability. When tying the reinforcement, the transverse reinforcement 211 is lapped onto the concealed beam reinforcement 221, and the longitudinal reinforcement 212 is lapped onto the transverse reinforcement 211. Please refer to the appendix for details. Figure 2 In other embodiments, the longitudinal reinforcing bars 212 can be lapped on the hidden beam reinforcing bars 221, and the transverse reinforcing bars 211 can be lapped on the longitudinal rib reinforcing bars to form a reinforcing mesh.

[0044] As a preferred embodiment of the present invention, the platform slab reinforcement assembly 210 further includes multiple layers of slab edge sealing reinforcement units arranged vertically at intervals. Each layer of the slab edge sealing reinforcement unit includes multiple slab edge sealing reinforcements 213 connected end-to-end along the circumferential direction of the platform slab segment 110. Among them, the two slab edge sealing reinforcements 213 near the ladder opening 111 are disconnected to form a slab edge sealing reinforcement unit distributed in a C-shape. The slab edge sealing reinforcements 213 overlap the hidden beam reinforcement 221.

[0045] It is worth noting that the edge sealing bar unit also adopts a multi-layer form to correspond to each layer of hidden beam reinforcement unit and platform slab reinforcement unit. The edge sealing bar 213 can effectively prevent cracks caused by negative bending moment due to boundary constraints, and is used to strengthen the edge structure of the slab and improve the end stress performance. Therefore, it is connected end to end along the circumferential direction of the platform slab segment 110 when it is tied. Considering that the platform slab segment 110 has a ladder opening 111, the two edge sealing bars 213 near the ladder opening 111 are not connected to each other and are in a disconnected form, thus forming a C-shaped distribution structure. The opening position of the C-shape is the location of the ladder opening 111. Preferably, the number is set to seven. The seven edge sealing bars 213 are spliced ​​to form a C-shaped structure. The edge sealing bars 213 are lapped on the hidden beam reinforcement 221. The ends of some transverse reinforcement 211 and longitudinal reinforcement 212 can also be lapped on the edge sealing bars 213.

[0046] Furthermore, the hidden beam reinforcement unit, the platform slab reinforcement unit, and the slab edge sealing reinforcement unit are all arranged in two layers at intervals along the top and bottom.

[0047] It should be noted that in this application, the multi-layered steel reinforcement units are all arranged in two layers, which are placed near the top and bottom of the beam and slab segments respectively. This is sufficient to ensure adequate structural strength while also saving on processing costs.

[0048] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
