Description

Technical Field

[0001] The present application relates to the field of floor slab technology, and in particular to a cast-in-place reinforced concrete floor slab. Background Art

[0002] Floor slabs are typically constructed using steel as a framework, then poured with concrete to form a slab. Cast-in-place reinforced concrete floor slabs are often used in buildings to connect adjacent load-bearing walls and bear some of the horizontal load, thereby helping to ensure the stability of the building structure.

[0003] Most existing cast-in-place reinforced concrete floors consist of a skeleton and a casting section. The skeleton is often a rectangular frame formed by bending steel bars, with multiple rectangular frames connected by welding. The casting section is a block formed by applying concrete slurry to the skeleton and then allowing the concrete slurry to solidify. The skeleton is entirely located within the casting section, and together, the skeleton and casting sections form the concrete floor.

[0004] However, the bearing strength provided by steel bars to the floor slab is limited, so the maximum load strength that the floor slab can withstand is often not high, which in turn affects the stability of the floor slab in natural disasters such as earthquakes. Summary of the Invention

[0005] In order to improve the problem of low maximum load strength of ordinary floor slabs, the present application provides a cast-in-place reinforced concrete floor slab.

[0006] The cast-in-place reinforced concrete floor provided in this application adopts the following technical solution:

[0007] A cast-in-place reinforced concrete floor slab comprises an internal connection portion and a concrete construction portion; the internal connection portion comprises a main bearing assembly and multiple groups of pressure-resistant assemblies, the main bearing assembly comprises a bottom connecting support plate, multiple groups of pre-installed units and multiple interconnecting plates; all the pre-installed units are spaced apart on the bottom connecting support plate, and one interconnecting plate is correspondingly arranged on a group of pre-installed units; one group of pressure-resistant assemblies is correspondingly arranged on one interconnecting plate, and the pressure-resistant assemblies are respectively connected to the bottom connecting support plate and the pre-installed units; the concrete construction portion comprises concrete blocks, and the internal connection portion is located inside the concrete blocks to jointly form a floor slab.

[0008] By adopting the above technical solution, the network panel is set on the bottom supporting plate through the pre-installed unit. The structural reinforcement of the bottom supporting plate and the pre-installed unit ensures the structural strength of the floor after forming, which helps to improve the compressive strength of the floor; the pressure-resistant components and the bottom supporting plate bear part of the impact force of the floor inside the concrete block to ensure the structural stability of the floor; the pressure-resistant components can also generate a tensile force relative to the bottom supporting plate inside the concrete block, so that the floor is not easy to crack or fault directly after being locally stressed, thereby ensuring the structural strength of the floor and improving the load strength of the floor.

[0009] In a specific possible implementation scheme, each group of the preinstalled units includes preinstalled square columns, which are arranged on the bottom supporting plate; the preinstalled square columns are provided with assembly grooves for the network boards to be inserted into, and the side walls of the preinstalled square columns are provided with multiple slurry guide channels for concrete slurry to pass through at the assembly grooves.

[0010] By adopting the above technical solution, the pre-installed square columns can quickly receive the interconnecting plates through the assembly grooves, and the slurry guide channels facilitate the rapid circulation of the concrete slurry used to form the concrete blocks inside and outside the pre-installed square columns, thereby greatly improving the connection tightness and strength between the interconnecting plates and the pre-installed square columns, thereby helping to improve the connection strength of the floor slab and its application stability after long-term use.

[0011] In a specific possible implementation manner, the height dimensions of all pre-installed square columns located on the bottom supporting plate increase or decrease from both ends to the middle of the bottom supporting plate.

[0012] By adopting the above technical solution, after all the pre-installed square columns with increasing or decreasing height sizes are distributed on the bottom connecting support plate, the impact force exerted on the floor slab will have different degrees of resistance when it is transmitted inside the floor slab, which will help to improve the overall seismic and compressive resistance of the floor slab.

[0013] In a specific feasible implementation scheme, each group of the pre-installed units also includes a limiting module, and the limiting module includes a support plate, an insert screw and a limiting nut; the support plate is arranged on the network plate, and the insert screw is arranged on the pre-installed square column; the insert screw is passed through the support plate, and the limiting nut is threadedly connected to the insert screw, so that the support plate is positioned on the pre-installed square column.

[0014] By adopting the above technical solution, the side support plates increase the contact area between the network plates and the pre-installed square columns. The screw rods are inserted through the network plates to limit the position of the network plates relative to the pre-installed square columns. The limit nuts are threaded on the screw rods to quickly fix the side support plates and the pre-installed square columns into a whole, which helps to improve the position stability of the network plates inside the concrete blocks and ensure the structural stability of the floor slab after formation.

[0015] In a specific possible implementation scheme, each group of the compression-resistant components includes a load support plate, a bottom support unit and a side support unit. The load support plate is arranged on the network plate. The load support plate is connected to the pre-installed square column through the bottom support unit. The load support plate is connected to the bottom connecting support plate through the side support unit.

[0016] By adopting the above technical solution, after the load support plate is connected to the pre-installed square column and the bottom support plate respectively, the stability of the load support plate in bearing external force impact is greatly improved; in addition, the load support plate can form a strong pulling force with the bottom support plate and the pre-installed square column, so that after the floor slab is locally subjected to force, the floor slab can be pulled against each other at various locations to assist in compressive resistance, thereby helping to improve the overall load strength of the floor slab.

[0017] In a specific possible implementation scheme, the bottom supporting unit includes a side supporting plate, a contact plate and an assembly bolt, one end of the side supporting plate is connected to the load support plate, the contact plate is arranged at the other end of the side supporting plate, and the assembly bolt is used to position the contact plate on the pre-installed square column.

[0018] By adopting the above technical solution, after assembling the bolt connection contact plate and the pre-installed square column, a triangular stable structure is formed between the side support plate, the pre-installed square column and the load support plate, which helps to ensure the position stability and pressure bearing strength of the load support plate, and ensures the connection strength between the load support plate and the pre-installed square column.

[0019] In a specific possible implementation scheme, the side support unit includes a force-guiding screw, a force-bearing screw and a transfer screw, and the force-guiding screw and the force-bearing screw are respectively threadedly connected to the opposite ends of the transfer screw, and the end of the force-guiding screw away from the transfer screw is connected to the load support plate, and the end of the force-bearing screw away from the transfer screw is connected to the bottom support plate.

[0020] By adopting the above technical solution, the adapter screw is threadedly connected to the guide screw and the force-bearing screw at the same time, so that the load support plate and the bottom support plate are quickly fixed and connected as a whole, thereby effectively ensuring the connection strength and tensile strength between the load support plate and the bottom support plate, and improving the overall structural stability and connection strength of the floor.

[0021] In a specific feasible implementation scheme, the cast-in-place reinforced concrete floor also includes an assembly part, which includes a plurality of abutting straight bars and a plurality of fixing components; all the abutting straight bars are arranged at intervals on the bottom connecting support plate, and the bottom connecting support plate is also provided with an insertion channel for inserting the abutting straight bars, and the fixing components are used to position the abutting straight bars in the side walls of the insertion channel.

[0022] By adopting the above technical solution, the abutting straight strips are inserted into the inner cavity of the insertion channel, so that the two bottom connecting support plates are quickly fixedly connected as a whole, and then the two groups of internal connection parts are assembled into a whole through a group of assembly parts to be positioned in a concrete part; this process greatly improves the structural strength and compressive strength of the floor slab after forming, so that the load strength of the floor slab can be further improved.

[0023] In a specific possible implementation scheme, each group of the fixing components includes a locking side plate and a fixing bolt. The locking side plate is arranged on the abutting straight bar, and the side wall of the bottom supporting plate is provided with an edge groove for the locking side plate to be inserted into the plug-in channel. The fixing bolt is used to position the locking side plate in the side wall of the edge groove.

[0024] By adopting the above technical solution, the locking side plate is pressed into the inner cavity of the edge groove to reduce the phenomenon of the abutting straight bar directly passing through the plug-in channel. The fixing bolts are fixedly connected to the locking side plate and the bottom connecting support plate, which ensures the connection strength of the two bottom connecting support plates and facilitates quick disassembly by the operator.

[0025] In summary, this application has the following beneficial technical effects:

[0026] 1. The bottom support plate ensures the structural strength of the floor after forming through its own material strength, which helps to improve the load strength of the floor;

[0027] 2. The load support plate and the bottom support plate are pulled against each other inside the concrete block, so that when the floor is locally stressed, it can obtain support from other positions, thereby reducing the phenomenon of excessive local stress directly causing cracks or even fractures in the floor, thus ensuring the structural stability and compressive strength of the floor;

[0028] 3. The abutting straight strip is inserted into the inner cavity of the insertion channel, so that the two bottom connecting support plates are connected as a whole, and then the two sets of internal connection parts are installed at the same time inside a concrete block, so that the structural strength and load strength of the floor after forming can be further improved, which helps to ensure the application stability of the floor after long-term use.

DETAILED DESCRIPTION

[0037] The embodiments of the present application disclose a cast-in-place reinforced concrete floor slab.

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] Example 1

[0040] Reference Figure 1 and Figure 2 The cast-in-place reinforced concrete floor comprises an internal connection part 1 and a concrete construction part 2. The internal connection part 1 further comprises a main bearing assembly 11, and each group of main bearing assemblies 11 comprises a bottom joint support plate 3, a plurality of pre-assembled units 4 and a plurality of network boards 5.

[0041] Reference Figure 2 and Figure 3 In this embodiment, the bottom support plate 3 can be a solid steel plate, and the meshing plate 5 is a mesh formed by welding multiple steel bars. All pre-assembled units 4 are spaced apart on the bottom support plate 3 and are evenly spaced along the length of the bottom support plate 3.

[0042] Reference Figure 2 and Figure 3 Each set of preassembled units 4 includes preassembled square columns 41. These solid steel columns are integrally formed on the bottom support plate 3. The height of the preassembled square columns 41 of all preassembled units 4 increases or decreases along the length of the bottom support plate 3 toward the middle. In this embodiment, the height of the preassembled square columns 41 at the ends of the bottom support plate 3 is greater than the height of the preassembled square columns 41 in the middle of the bottom support plate 3.

[0043] Reference Figure 3Each pre-installed square column 41 has an end wall away from the bottom support plate 3, which is provided with an assembly groove 411. The assembly groove 411 is used to receive one end of the network board 5, so that the network board 5 can be quickly installed on the pre-installed square column 41. At this time, the end of the network board 5 away from the pre-installed square column 41 is located above the pre-installed square column 41.

[0044] Reference Figure 1 and Figure 2 Concrete section 2 includes concrete blocks 21. In this embodiment, concrete blocks 21 are formed by solidifying concrete slurry. The operator pours concrete slurry into internal connecting section 1, completely enveloping it. The concrete solidifies to form concrete blocks 21. At this point, internal connecting section 1 is located within concrete section 2, and the two together form the floor slab.

[0045] Reference Figure 2 and Figure 3 In order to improve the positioning stability of the network board 5 on the pre-installed square column 41, a plurality of slurry guide channels 412 are also provided on the pre-installed square column 41. The inner cavity of each slurry guide channel 412 is connected to the inner cavity of the adaptation groove, so that the concrete slurry used to form the concrete block 21 can flow outside the adaptation groove, the slurry guide channel 412 and the pre-installed square column 41. When the concrete slurry is solidified into the concrete block 21, it helps to improve the connection strength between the network board 5 and the pre-installed square column 41.

[0046] Reference Figure 3 and Figure 4 In addition, to reduce the displacement of the interconnecting plate 5 relative to the pre-assembled square column 41 during the pouring of the concrete blocks 21, the pre-assembled unit 4 also includes a limiting module 42. The limiting module 42 includes a side support plate 421, a screw rod 422, and a limiting nut 423. The side support plates 421 are welded to both sides of the interconnecting plate 5 in the width direction, and the screw rod 422 is welded to the end wall of the pre-assembled square column 41 away from the bottom support plate 3.

[0047] Reference Figure 4 After the networking board 5 is inserted into the inner cavity of the adapter groove, the fixing screw rod 422 passes through the support plate 421, and the limiting nut 423 is threadedly tightened on the fixing screw rod 422, so that the support plate 421 is fixed on the pre-installed square column 41, thereby making the networking board 5 and the pre-installed square column 41 fixedly connected as a whole, ensuring the position stability and connection strength of the networking board 5 on the pre-installed square column 41.

[0048] Reference Figure 3To improve the compressive strength of the floor, the internal connection portion 1 also includes multiple groups of compression-resistant components 12, with one group of compression-resistant components 12 correspondingly disposed on a network plate 5. Each group of compression-resistant components 12 includes a load support plate 6, a bottom support unit 7, and a side support unit 8. The load support plate 6 is horizontally welded to the side wall of the network plate 5 away from the pre-installed square column 41, and the outer circumference of the load support plate 6 is larger than the outer circumference of the longitudinal end of the network plate 5. When the floor is impacted by external forces, the load support plate 6 can absorb part of the impact force and, through its larger surface area, generate a tensile force relative to the bottom support plate 3 within the concrete block 21, thereby ensuring the structural strength of the floor and improving the load resistance of the floor.

[0049] Reference Figure 3 and Figure 4 The bottom support unit 7 is used to connect the load support plate 6 and the pre-assembled square column 41 to improve the compressive strength of the load support plate 6. The bottom support unit 7 includes a side support plate 71, a contact plate 72, and assembly bolts 73. One end of the side support plate 71 in the longitudinal direction is welded obliquely to the side wall of the load support plate 6 facing the bottom connecting support plate 3. The contact plate 72 is welded vertically to the end of the side support plate 71 away from the load support plate 6 and abuts the outer wall of the pre-assembled square column 41.

[0050] Reference Figure 4 The assembly bolt 73 passes through the contact plate 72 and is screwed into the preset thread groove on the outer wall of the pre-installed square column 41, so that the contact plate 72 is fixedly connected to the pre-installed square column 41, thereby making the pre-installed square column 41, the side support plate 71 and the load support plate 6 form a stable triangular structure together, which helps to improve the compressive strength of the load support plate 6.

[0051] Reference Figure 3 The side support unit 8 is used to connect the load support plate 6 and the bottom support plate 3 to improve the position stability of the load support plate 6. The side support unit 8 includes a force guide screw 81, a force bearing screw 82 and a transfer screw 83. In this embodiment, the transfer screw 83 can be an internal threaded sleeve.

[0052] Reference Figure 3 One end of the guide screw 81 is vertically welded to the side wall of the load support plate 6 facing the bottom support plate 3. The adapter screw 83 is threadedly connected to the guide screw 81, and the adapter screw 83 can be screwed to allow the guide screw 81 to pass through the adapter screw 83. The force-bearing screw 82 is vertically welded to the bottom support plate 3. The force-bearing screw 82 is located below the guide screw 81. The central axis of the force-bearing screw 82 is collinear with the central axis of the force-bearing screw 81, and the force-bearing screw 82 and the guide screw 81 are clearance-fitted.

[0053] Reference Figure 3After the load support plate 6 is installed on the interconnecting plate 5, the operator screws the adapter screw 83 so that the end of the adapter screw 83 away from the guide screw 81 is threaded onto the force-bearing screw 82. At this point, the adapter screw 83 is simultaneously threaded onto the guide screw 81 and the force-bearing screw 82, thereby connecting the load support plate 6 to the bottom support plate 3. This ensures the positional stability of the load support plate 6 and helps to improve the compressive strength of the load support plate 6 and the floor slab.

[0054] The implementation principle of the cast-in-place reinforced concrete floor in the embodiment of the present application is as follows: the steel bottom connecting plate 3 and the pre-installed square columns 41 enhance the compressive strength of the floor after forming, and reduce the possibility of direct breakage of the floor after being impacted by external forces; the network plate 5 is used to increase the connection tightness and connection strength between the concrete blocks 21 and the pre-installed square columns 41 and the bottom connecting plate 3, thereby ensuring the structural strength of the floor after forming.

[0055] When the floor is impacted by external forces, the load support plates 6, pre-assembled square columns 41, and bottom joint support plates 3 can sequentially absorb the impact force, ensuring the structural stability of the floor. Furthermore, the load support plates 6 can generate a tensile force against the bottom joint support plates 3 within the concrete blocks 21, thereby enhancing the overall structural strength of the floor, reducing the risk of cracking or fracture in the floor due to localized stress, and significantly improving the overall load bearing capacity of the floor.

[0056] Example 2

[0057] The difference between Example 2 of the present application and Example 1 is that, referring to Figure 5 The cast-in-situ reinforced concrete floor further comprises an assembling portion 9. The assembling portion 9 is used to assemble two groups of internal connecting portions 1 so that the two groups of internal connecting portions 1 are wrapped in a concrete block 21, thereby improving the compressive strength of the entire floor.

[0058] Reference Figure 6 The assembly portion 9 includes a plurality of abutting bars 91 and a plurality of fixing components 92. The abutting bars 91 are long bars with dovetail grooves, and all of the abutting bars 91 are integrally formed on the bottom wall of the bottom joint support plate 3. The abutting bars 91 are spaced and evenly spaced along the length of the bottom joint support plate 3, and each abutting bar 91 extends along the width of the bottom joint support plate 3.

[0059] Reference Figure 6 The bottom support plate 3 is further provided with a plurality of insertion channels 31. The inner diameter of each insertion channel 31 matches the outer circumference of the abutting straight bar 91, and each insertion channel 31 extends along the width of the bottom support plate 3. In this embodiment, each insertion channel 31 is provided every other abutting straight bar 91, and each insertion channel 31 is used to receive the abutting straight bar 91.

[0060] Reference Figure 6Each set of fixing components 92 includes a retaining side plate 921 and a fixing bolt 922. The retaining side plate 921 is integrally formed on the side wall of the abutting straight bar 91 away from the bottom connecting support plate 3, and is located at one end of the abutting straight bar 91 in the longitudinal direction. A side connection groove 32 is also provided on the side wall of the bottom connecting support plate 3, located at each insertion channel 31. The inner cavity of the side connection groove 32 communicates with the inner cavity of the insertion channel 31, and the inner diameter of the side connection groove 32 matches the outer circumference of the retaining side plate 921.

[0061] Reference Figure 5 and Figure 6 When two sets of internal connecting parts 1 are assembled using a set of assembly parts 9, the abutment bars 91 on one bottom joint support plate 3 are inserted into the insertion channel 31 of the other bottom joint support plate 3 until the retaining edge plate 921 is inserted into the inner cavity of the edge connection groove 32. The operator can then pass the retaining bolts 922 through the retaining edge plate 921 and tighten them into the pre-set thread grooves in the edge connection groove 32, securing the retaining edge plate 921 to the side wall of the edge connection groove 32. At this point, the two bottom joint support plates 3 are fixedly connected as a whole, which helps to improve the compressive strength of the finished floor slab.

[0062] The implementation principle of the cast-in-place reinforced concrete floor slab in the embodiment of the present application is as follows: by abutting the straight bar 91 into the inner cavity of the plug-in channel 31, the fixing bolts 922 are used to fix the locking side plate 921 and the bottom connecting support plate 3, so that the two bottom connecting support plates 3 are fixedly connected as a whole, and then the two groups of internal connection parts 1 are assembled as a whole for use, which helps to improve the compressive strength of the floor slab after forming.

[0063] 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.
