Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a support structure for reinforced concrete. Background Technology

[0002] Concrete floor slabs, as key horizontal load-bearing and partitioning components of a building, are constructed from concrete and steel reinforcement. Concrete, with its excellent compressive strength, bears various static and dynamic loads from above, such as the weight of people during daily activities, the pressure of furniture and appliances, and potential vibrations from small equipment, providing stable support for the building space. Steel reinforcement, with its superior tensile strength, crisscrosses within the floor slab, tightly bonding with the concrete, effectively enhancing the overall bending and shear resistance of the floor slab and preventing cracks and fractures under complex stress conditions. In actual construction, ensuring the precise thickness of the concrete floor slab and that the thickness of the steel reinforcement cover meets standards is particularly important. The thickness of the slab is directly related to the load-bearing capacity, space utilization, and the realization of functions such as sound insulation and heat preservation. If it is too thin, it cannot bear the expected load, while if it is too thick, it will cause waste of resources and space compression. The thickness of the concrete cover, as a key barrier between concrete and steel bars, not only blocks the invasion of external air, moisture and corrosive chemicals into the steel bars, ensuring the integrity of the steel bar structure and preventing the volume expansion caused by corrosion, which would lead to cracking and spalling of the concrete, but also allows the steel bars to be precisely positioned, so that they can fully exert their strength under the design stress mode, laying a solid foundation for the structural safety and service durability of the concrete slab throughout its entire life cycle.

[0003] Under current technology, formwork is erected before pouring concrete floor slabs. Leveling instruments and total stations are used to precisely mark elevation control lines, which serve as a reference for the pouring thickness. Then, a reinforcing steel structure is built inside the formwork, with spacers placed at the bottom of the steel bars to ensure a gap between the steel bars and the bottom of the formwork, thus determining the concrete cover. However, this construction method has many drawbacks. Regarding the marking of elevation control lines, the measuring instruments are easily affected by the complex environment of the construction site, such as temperature changes, limitations in the instrument's own accuracy, and differences in the skill level of the operators. These factors can all lead to deviations in the elevation control lines, resulting in uneven floor slab thickness and affecting the structural load-bearing capacity. Regarding the determination of the concrete cover, the spacers may shift during concrete pouring due to vibration, causing instability in the concrete cover thickness. This fails to effectively protect the steel bars from corrosion, reducing structural durability. From the perspective of overall construction efficiency, the operation and calibration of measuring instruments, as well as the repeated verification of elevation control lines, coupled with the meticulous arrangement of spacers during the construction of the steel structure, all require a lot of time and manpower. The cumbersome procedures greatly slow down the construction progress, increase construction and time costs, and are not conducive to the efficient advancement of the project. Utility Model Content

[0029] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example

[0030] Please refer to Figure 1 This application provides a support structure for reinforced concrete, including: a bearing 100 for supporting the reinforced concrete; a positioning plate 400 arranged parallel to and at intervals from the bearing 100; and a support 200 for connecting the bearing 100 and the positioning plate 400; wherein the support 200 is located between the bearing 100 and the positioning plate 400.

[0031] This application of a support structure for reinforced concrete offers significant advantages. Regarding the determination of concrete slab thickness, since the lower side of the positioning plate 400 is precisely the surface of the concrete slab, construction workers can directly use the positioning plate 400 as a reference to accurately control the concrete pouring height, ensuring the concrete slab reaches the designed thickness and avoiding uneven thickness that could affect structural strength. From the perspective of determining the thickness of the concrete cover, the distance from the bottom of the reinforcing bar placed on the upper side of the bearing 100 to the bottom of the bearing 100 is the thickness of the concrete cover, making the thickness readily apparent. This crucial dimension can be precisely maintained during construction, effectively preventing corrosion of the reinforcing bar due to insufficient cover thickness and ensuring the durability of the concrete structure. Furthermore, in actual operation, this complete support system, consisting of the bearing 100, the positioning plate 400, and the supporting structure 200 between them, eliminates the need for repeated measurements and calculations. A single operation can simultaneously determine both the concrete slab thickness and the concrete cover thickness, greatly improving construction efficiency and making the entire reinforced concrete support operation more scientific, precise, and efficient.

[0032] As a preferred embodiment, the support 200 is a hollow structure.

[0033] In the above embodiment, when concrete is poured, the concrete can smoothly penetrate into the hollow structure of the support 200. On the one hand, this greatly enhances the bond between the support 200 and the concrete, making the support structure more stable inside the concrete and less prone to displacement or loosening, providing continuous and reliable support and protection for the steel reinforcement in the concrete. On the other hand, the concrete penetrating the hollow structure fills the gaps in the support 200, which is equivalent to forming many additional "micro-supports" on the basis of the original support system, further improving the load-bearing capacity of the entire support structure, better coping with the various stresses applied during concrete solidification, shrinkage, and subsequent use, and ensuring the long-term stability of the concrete-reinforced structure.

[0034] In a preferred embodiment, the bearing 100 is provided with a groove 300 on the side facing the positioning plate 400 for fitting the concrete reinforcement.

[0035] In the above embodiment, during construction, the concrete reinforcing bars can be precisely embedded in the groove 300, avoiding unstable conditions such as rolling and displacement of the reinforcing bars on the bearing body 100, ensuring that the position of the reinforcing bars is fixed, so that the layout of the reinforcing bars fully meets the design requirements when pouring concrete later, and ensuring that the overall stress of the concrete structure is uniform.

[0036] In a preferred embodiment, the number of the aforementioned carriers 100 is two;

[0037] The two aforementioned carriers 100 are arranged in parallel and spaced apart, and the plane formed by the two aforementioned carriers 100 is parallel to the aforementioned positioning plate 400.

[0038] In the above embodiments, the dual-bearing-body 100 structure can provide more stable and balanced support for the reinforcing bars. Compared with a single bearing body 100, it can effectively distribute the weight of the reinforcing bars, avoid deformation or damage of the bearing body 100 due to excessive local stress, and ensure the stable placement of the reinforcing bars during construction. Example

[0039] Please refer to Figures 2-6 This embodiment is the same as the main body of embodiment 1. The main difference is that the support body 200 includes a first support plate 201, a plurality of support units 202 and a second support plate 203 arranged in sequence and overlapping each other. The first support plate 201 and the second support plate 203 are respectively connected to the carrier 100 and the positioning plate 400.

[0040] The first support plate 201 and the connected support unit 202, adjacent support units 202, and the second support plate 203 and the connected support unit 202 are all connected by a detachable structure 600.

[0041] In the above embodiment, the support body 200 is composed of a first support plate 201, multiple support units 202, and a second support plate 203 stacked sequentially, with each connecting part being a detachable structure 600. During transportation, the support body 200 can be disassembled, which significantly reduces the overall space occupied, making it easier to handle and store, and thus reducing transportation costs. At the construction site, if some support units 202 are damaged, they can be quickly replaced due to their detachable nature, without delaying the overall construction progress and ensuring the project is completed on time. In addition, the number of support units 202 can be flexibly increased or decreased according to the thickness requirements of different concrete slabs, realizing the height adjustment between the positioning plate 400 and the load-bearing body 100. It is applicable to both thick and thin concrete slabs, making it highly practical.

[0042] In a preferred embodiment, the detachable structure 600 includes a first connecting plate 601, a second connecting plate 602, and a bolt 603. The first connecting plate 601 and the second connecting plate 602 are respectively disposed on the first support plate 201 and the support unit 202 that is connected thereto, or on two adjacent support units 202, or on the second support plate 203 and the support unit 202 that is connected thereto.

[0043] The first connecting plate 601 and the second connecting plate 602 are connected by the bolts 603.

[0044] In the above embodiment, the first connecting plate 601 and the second connecting plate 602 are connected by bolts 603. This allows the detachable structure 600 to be quickly disassembled or installed, providing excellent adaptability whether it is for disassembling components during transportation to save space or for rapid adjustment of the support structure when constructing concrete slabs of different thicknesses. Both the first connecting plate 601 and the second connecting plate 602 are provided with threaded holes, and these threaded holes can be precisely aligned to perfectly fit the bolts 603, ensuring the stability and reliability of the connection. This ensures that the connection method can function efficiently and stably in various application scenarios, providing strong support for the entire construction process.

[0045] In a preferred embodiment, plug-in structures are provided between the first support plate 201 and the connected support unit 202, between adjacent support units 202, and between the second support plate 203 and the connected support unit 202.

[0046] In the above embodiments, the plug-in structure enables rapid docking of various components (between the first support plate 201 and the connected support unit 202, between adjacent support units 202, or between the second support plate 203 and the connected support unit 202), and further ensures the stability of the connection of various components.

[0047] In a preferred embodiment, the above-mentioned plug-in structure includes a plug-in mating slot 700 and a plug strip 500. The slot 700 and the plug strip 500 are respectively disposed on the first support plate 201 and the support unit 202 that docks with it, or two adjacent support units 202, or the support unit 202 that docks with the second support plate 203 and the second support plate 203.

[0048] In particular, the slots 700 of the multiple support units 202 are all facing the second support plate 203.

[0049] In the above embodiment, during construction, workers only need to align the insert 500 with the slot 700 and insert it to quickly complete the connection of each component. The operation is simple and convenient, which greatly improves the assembly efficiency of the support 200 and reduces construction time and labor costs.

[0050] Preferably, the cross-sections of the slot 700 and the insert block 500 are both T-shaped to prevent the components from falling off during connection and to improve the stability of the connection.

[0051] In a preferred embodiment, the first support plate 201, the second support plate 203, and the plurality of support units 202 are all hollow structures.

[0052] In the above embodiments, during the construction of reinforced concrete support, the use of a hollow structure allows concrete to pass through each component without obstruction and fully fill the gaps. This results in a tighter and stronger connection between the support structure and the concrete, significantly improving their bonding strength.
